DESCRIPTION OF THE PROPOSAL The Building and Planning Department received a Sp e cial Us e Permit (SUP) application for "Temporary Employee Housing " facil ity on property owned by Chevron USA, Inc located on an approximately 54,000 acre property approximately 20 .5 miles North of the DeBeque, CO . More specifically, the Applicant requests approval for one Temporary Employee Housin g facility to house personnel for the purpose of natural gas drill ing operations . A ccording to the Applicant: Proposed Use Chevron USA, Inc. -Temporary Employee Housing-598-36-BV BOCC-Il.17.08 Page2 Chevron is seeking approval of a Special Use Pe1mit for n temporary employee housing site on the Skinner Ridge (SKR) 598-36-BV well pnd, located Jn Scction 36 of Township 5 Soutl1, Range 98 West of tl1e 6°1 Principal Meridian in Garfield County, Colorado (please see the location maps in Exhibit I). The SKR 598-36-BV is located on Chevron- owned property within the Resource Lands zone district; approximately 20 miles north of DeBeque (please see the Affidavit of Surface Ownership in Exhibit 5). Currently, there is not sufficient housing in DeBeque and the Sllltounding area to accommodate oil and gas operations, and the driving time from towns with available housing ranges from one to two or more hours each way, depcndh1g on weather conditions. The drilling crew and all of the support personnel will be working a 12-hour-on, 12-hour-off shift. In the interest of safety and respect for employees and the comnmnity, it is impo11ant thal Chevron be allowed to provide permitted on-site housing for its employees (Please sec section 9, Special Use Permits for Temporary Employee Housing for further infmmation). This site is remote and the housing is intended to be contained on an approved COGCC well pad along with other drilling facilities. The Temporary Employee Housing facility will be in use year around to accommodate those considered to be "essential personnel" to the drilling operations. The housing facility, however, will not be at location for more than a cumulative of one year. The maximum number of people to be housed at a facility will be 24. The Applicant has stated that operations are anticipated to begin on the 598-36-BV well pad in October, 2008, to coincide with the commencement with drilling there. There are 22 wells anticipated for this well pad and drilling operations are to take approximately 330 days from commencement. Housing Structures The installed facility is required to meet all applicable building and fire code requirements. The facility is to accommodate up to 24 people at any one given time. The Applicant has represented that the facility will have a minimum of 6720 gallons of potable water storage. Sewage and wastewater are proposed to be handled by a vault-and-haul system with a minimum of three 2,000 gallon tanks (6,000 gallon total). Based on the State ISDS regulation requirements, Staff recommends that the Applicant provide a minimum of 75 gallons per person per day of storage capacity for wastewater collection. Water: Potable water is to be hauled to the facility using water hauling contractors. The Applicant is required to use CDPHE-certified potable water haulers who are obtaining the water from an approved source. All water must be treated prior to delivery to a facility. The Applicant represents that the facility will be supplied with a 6720 gallon supply of potable water. Staff recommends that the water systems be designed to accommodate the maximum occupancy for the facility. At the recommended calculation of 75 gallons of water per day, the Chevron USA, Inc. -Temporary Employee Housing-598-36-BV BOCC-11.17.08 Page3 stated 6720 gallons will provide a 3.73 day supply of potable water. Staff finds that adequate water is to be provided to the facility. Sewage: A vault-and-haul system (minimum tank capacity of 6,000 gallons) will handle sewage and wastewater. Based on the State ISDS regulation requirements, Staff recommends that the Applicant provide a minimum of 75 gallons per person per day of storage capacity for wastewater collection for the maximum occupancy for each facility. As taken from the Applicants' calculation of the maximum number of beds for each facility, the facility is anticipated to handle up to 24 persons. As a result, the 6,000 gallon tank is anticipated to provide a 3.33 day capacity. As long as the tanks are emptied at least every 3 days, Staff finds that adequate sewage and wastewater storage is available for the facility. In addition, the Applicant has provided a letter from Hyland Enterprises, Inc. indicating that they provide road maintenance and snow removal for the access road to the facility. Refuse: At least one thirty-gallon, bear-proof refuse receptacle that will be emptied by a refuse hauler at least once per week will provide refuse disposal for the site. Refuse is proposed to be disposed of either at the Mesa County landfill or the Garfield County landfill. Density: All portions of this facility are to be located within the Resource Land zone district and within a COGCC approved well pad, therefore the density requirements do not apply to this development. Proximity to Permanent Available Housing: The Applicant has states that "Currently, there is not sufficient housing in DeBeque and the surrounding area to accommodate oil and gas operations, and the driving time from towns with available housing ranges from one to two or more hours each way, depending on weather conditions." Staff concurs that onsite housing will assist in alleviating the current Garfield County housing shortage as well as those in nearby Mesa County. In addition, it is Staff's opinion that onsite housing will promote safety on the drilling rigs as well as reduce the overall amount of traffic on Garfield County and State of Colorado roadways. Renewal: The maximum allowable time length of the Special Use Permit for Temporary Employee Housing is one (1) year; however, no single Temporary Employee Housing facility allowed under this Special Use Permit shall be onsite for more than a cumulative of one year. For good cause shown, the permit may be renewed annually in a public meeting with notice by agenda only. Annual renewal review shall be based on the standards herein as well as all conditions of the permit. A permit may be revoked anytime through a public hearing called up by staff or the Board of County Commissioners. Reclamation and Revegetation: Chevron USA, Inc. -Temporary Employee Housing-598-36-BV BOCC-11.17.08 Page4 All housing structures and associated equipment will be located on the COGCC-approved well pad. As such, reclamation is to be handled by the Colorado Oil and Gas Conservation Commission and secured through the appropriate bond. REVIEW CRITERIA FOR SPECIAL USE PERMITS !SECTION 5:03) Pursuant to Section 5.03, as listed under the Zone District Regulations, special uses shall conform to all requirements listed there under and elsewhere in the Zoning Resolution, as well as the following standards: 1. Utilities adequate to provide water and sanitation service based on accepted engineering standards and approved by the Board of County Commissioners shall either be in place or shall be constructed in conjunction with the proposed use. Response Staff feels that this standard is satisfied; the provisions made for water hauling and sewage disposal cited above combined with the staff-recommended conditions will address these needs. 2. Street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe, convenient access to the use shall either be in place or shall be constructed in conjunction with the proposed use. Response Overall, the approval of this Special Use Permit for Temporary Employee Housing will reduce traffic on the access roads to the site. For this reason, staff feels that additional road improvements are not necessary. The Garfield County Road and Bridge Department had the following comments regarding this application: Garfield County Road & Bridge Department has no objection to this application with the following comments (See Exhibit F): "Garfield County Road & Bridge Department has no objections to this application with the following comments. We recognize the need for temporary housing for employees in the oil and gas industry as housing is almost unavailable in the valley. The traffic impact on Cr. 204 and Cr. 211 will decrease without the daily trips of employees reducing the impact to Cr. 204 and Cr. 211 and increase the safety of all users of these roads. The driveway access use will be exempted as the driveway access will be a permitted as a well pad driveway access. All vehicles hauling equipment and materials for this project will abide by Garfield Counties oversize/overweight permit system. All vehicles requiring an oversize/overweight permit shall have on file with Garfield County Road & Bridge Department a letter from Chevron USA Inc. stating such vehicles can apply for permits under their road bond on file with Garfield County." Che vron USA, In c. -Te mp orary Emp loyee H ous ing -598-36-B V BOCC -11.1 7.08 Page 5 3. Design of the proposed use is organized to minimize impact on and from adjacent uses of land through installation of screen fences or landscape materials on the periphery of the lot and by location of intensively utilized areas, access points, lighting and signs in such a manner as to protect established neighborhood character. Response As this property is already characterized by intense industrial gas development, located entirely on approved COGCC drill pads and will ultimately reduce the amount of traffic to and from the site, it is Staff's opinion that this Temporary Employee Housing facility will not adversely affect any nearby neighbors as proposed . Garfield County Vegetation Management stated that the Applicant had submitted a weed map of the Clea r Creek area and that no major infestations of weeds listed on the GarCo noxious weed lists exist on the site, threatening adjacent properties and uses . (See Exhibit G): II. BACKGROUND This application for Temporary Employee Housing is to be located on Chevron 's Skinner Ridge 598-36 -BV well pad .

Last Revised: 02/2006 SKR 598-36-BV Temporary Housing Chevron U.S.A., Inc. I. APPLICATION SUBMITTAL REQUIREMENTS As a minimum, specifically respond to all the following items below and attach any additional information to be submitted with this application: J. Please submit, in narrative form, the nature and character of the Special Use requested. Submit plans and supporting information (i.e. letters from responsible agencies). Include specifications for the proposed use including, but not limited to, the hours of operation, the number and type of vehicles accessing the site on a daily, weekly and/or monthly basis, and the size and location of any existing and/or proposed structures that will be used in conjunction with the proposed use, and provisions for electric power service and any other proposed utility improvements. Be specific. Proposed Use Chevron is seeking approval of a Special Use Permit for a temporary employee housing site on the Skinner Ridge (SKR) 598-36-BV well pad, located in Section 36 of Township 5 South, Range 98 West of the 6th Principal Meridian in Garfield County, Colorado (please see the location maps in Exhibit 1). The SKR 598-36-BV is located on Chevron- owned property within the Resource Lands zone district; approximately 20 miles north of DeBeque (please see the Affidavit of Surface Ownership in Exhibit 5). Currently, there is not sufficient housing in DeBeque and the surrounding area to accommodate oil and gas operations, and the driving time from towns with available housing ranges from one to two or more hours each way, depending on weather conditions. The drilling crew and all of the support personnel will be working a 12-hour-on, 12-hour-off shift. In the interest of safety and respect for employees and the community, it is important that Chevron be allowed to provide permitted on-site housing for its employees (Please see section 9, Special Use Permits for Temporary Employee Housing for further information). Traffic Estimations Chevron is proposing the SKR 598-36-BV temporary housing facility to reduce traffic on County roads out of concern and respect for the safety of employees and the community. The temporary employee housing facility will be on Chevron's SKR 598-36-BV well pad, located approximately 20 miles northwest of DeBeque. The site is accessible via County Road 204 north from DeBeque to County Road 211. County Road 211 continues north for several miles before terminating at the private road that accesses Chevron's property. The SKR 598-36-BV well pad is located directly off of this private road, approximately three miles north of the termination point of County Road 211. Chevron contracted a traffic count in September, 2006 to analyze current traffic numbers (see Exhibit 7). Three counters were placed: one on County Road 204, just north of the County line at Mesa County Road Xl/2; one on County Road 204, just north of the intersection with County Road 213; and one on County Road 211, just north of the intersection with County Road 211. - l - SKR 598-36-BV Temporary Housing Chevron U.S.A .• Inc. The bulk of the traffic (87%) currently turns right on Logan's Road, or further up on CR 213, which are routes to other operator's sites. The remaining traffic volume shown in the study branches off at the intersection of County Road 204 and County Road 211, with nine percent traveling right on CR 211 in the direction of Chevron's property, and four percent turning left and continuing on CR 204. Overall, the temporary housing facility is intended to significantly reduce traffic on County Roads 204 and 211 by eliminating a substantial amount of worker/commuter travel. The SKR 598-36-BV temporary employee housing is designed to house 20 to 24 Chevron employees at a time. It is anticipated that the personal vehicles on-site at the temporary housing facility may number between 15 and 20 at any time. Although, employees will be allowed to have their personal vehicles on-site, unnecessary personal vehicle use will be discouraged and car-pooling will be encouraged whenever possible. Therefore, it is expected that the SKR 598-36-BV temporary housing facility will eliminate approximately 20 commuter round-trips per day. Accessory traffic associated with the SKR 598-36-BV temporary housing facility is expected to be as follows: Source Tvoe of Vehicle Number of Round-trips Initial delivery of buildings Heavy Hauling Truck 10 round-trips total and facilities Potable water deliverv Water Truck 3 round-trios oer week Drinking water service Deliverv Truck 2 round-trio oer week Sewage service Sewage Truck 3 round-trio oer week Trash Trash Truck 1 round-trip per week Removal of buildings and Heavy Hauling Truck 10 round-trips total facilities All roads used to access the SKR 598-36-BV site (CR 204, CR 211, Chevron's private road) are designed and maintained to provide safe and adequate access for the anticipated types and amounts of traffic associated with oil and gas development, specifically the temporary employee housing facility. Utilities All electrical power to the temporary employee housing site will be provided by the drilling rig generators. There will be a transformer on location that will transform three- phase 480-volt, and has the capacity to supply the trailers. Telephone service will be supplied via employee cellular phones. A land line is available at the Hiner Gate, should a land line become necessary. No additional land lines will be installed for the temporary employee housing site. - 2 - SKR 598-36-BV Temporary Housing Chevron U.S.A.,Inc. 2. .lf you will be using water or will be treating wastewater in conjunction with the proposed use, please detail the amount of water that would be used and the type of wastewater treatment . .lf you will be utilizing well water, please attach a copy of the appropriate well permit and any other legal water supply information, including a water allotment contract or an approved water augmentation plan to demonstrate that you have legal and adequate water for the proposed use.

At least one 30-gallon bear-proof refuse container will be provided for each unit, or the equivalent, in a central trash collection facility. Containers will be constructed of a durable, washable, non-absorbent metal with tight-fitting lids. In addition, Chevron will provide one or more large bear-proof roll-off dumpsters to accommodate trash on-site. Down Valley Septic and Drain will provide trash pick-up at least weekly, and more often, if necessary. (C) Outdoor food storage is prohibited unless facilities that prevent the attraction of animals to the temporary employee housing sites are provided. Outdoor food storage is prohibited on all Chevron temporary employee housing sites. (D) The applicant shall provide a detailed map and GPS coordinates to the Garfield County Sheriff's Office and the relevant Fire Protection District which is sufficient for emergency response purposes, including location of the temporary employee housing site; private and public roadways accessing the site, marked as open, gated and/or locked; and detailed directions to the site from a major public right-of-way. The map is subject to approval by the Garfield County Sheriff's Office and relevant Fire Protection District. The maps prepared for this site include GPS coordinates, as well as the location of the temporary employee housing site, private and public roadways accessing the site, and detailed directions to the site from CR 211. Please see the maps located in Exhibits 1 and2. The only gate that emergency response personnel would encounter en route to the temporary employee housing site is the Hiner Gate, located approximately three miles south of the proposed temporary employee housing location. The Hiner Gate is manned twenty-four hours a day, seven days a week, so the Gate will not present a problem for any emergency response personnel attempting to access the temporary housing unit. (6) If structures, requiring Building Permits under the Garfield County Building Code, are constructed for the commercial, industrial, highway project or mineral extraction related to the Special Use Permit for Temporary Employee Housing, upon expiration or revocation of the permit, Certificates of Occupancy for such structures shall be withheld until the temporary living quarters are removed and the site is restored to the satisfaction of the County Building and Planning Director. -12 - SKR 598-36-BV Temporary Housing Chevron U.S.A., Inc. Upon completion of the associated project and/or upon expiration or revocation of the permit, all structures related to the Special Use Permit for Temporary Employee Housing will be removed and the SKR 598-36-BV pad site will continue to operate as a well pad under the jurisdiction of the COGCC. (7) If a Special Use Permit for Temporary Employee Housing is granted, the applicant shall notify the County when site development begins. The applicant shall verify, in writing, by site plan and through photo documentation that the site water system and sewage disposal system were designed, installed and inspected in accordance with the said Special Use Permit and comply with all applicable regulations, permits and conditions. All written documentation and site plans verifying compliance must be stamped by a certified Colorado Engineer. The County also reserves the right to inspect a site, without notice, to assess compliance with the Special Use Permit for Temporary Employee Housing. A determination of noncompliance with any Special Use Permit for Temporary Employee Housing, or condition approval thereof, is grounds for revocation or suspension of said permit, in accordance with Section 9.01.06. Chevron will notify the County when site development begins. The office trailers and associated sleeping quarters necessary for the essential personnel must, logistically, be set in place before the drill rig is moved onto the well pad. In the interest of efficiency and safety, all of the housing facilities, for both essential and non-essential personnel, will be placed on site at that time. However, the non-essential personnel accommodations will remain uninhabited, if necessary, until the Garfield County Special Use Permit can be secured. Chevron will verify, in writing, by site plan and through photo documentation that the site water system and sewage disposal system were designed and installed and inspected in accordance with the said Special Use Permit and comply with all applicable regulations, permits and conditions. All written documentation and site plans verifying compliance will be stamped be a certified Colorado Engineer. (8) If there is suitable permanent housing inventory available in an area near the commercial, industrial, highway project or mineral extraction operation, as determined at the discretion of the BOCC, the Special Use Permit for Temporary Employee Housing shall not be granted. The SKR 598-36-BV is located on Chevron-owned property within the Resource Lands zone district, approximately 20 miles north of DeBeque. Currently, there is not sufficient -13 - SKR 598-36-BV Temporary Housing Chevron U.S.A., Inc. housing in DeBeque and the surrounding area to accommodate oil and gas operations, and the driving time from towns with available housing ranges from one to two or more hours each way, depending on weather conditions. The drilling crew and all of the support personnel will be working a 12-hour-on, 12-hour-off shift. In the interest of safety and respect for employees and the community, it is important that Chevron be allowed to provide permitted on-site housing for these employees. (9) No animals shall be allowed at temporary employee housing sites. No animals are allowed at any Chevron temporary employee housing site. (JO) Jn evaluating a request for a Special Use Permit for Temporary Employee Housing, the County Commissioners may require compliance with additional conditions of approval as may be needed to ensure the health, safety and welfare of the public. (A.81-263) Chevron will comply with all conditions of approval under this Special Use Permit, and any other additional conditions of approval required by the County Commissioners to ensure health, safety and welfare of the public. (11) The applicant shall submit, as part of the Special Use Permit for Temporary Employee Housing, a reclamation and revegetation plan for each specific site, addressing all points in section eleven (JI) within this Section 5.02.21. a. Debris and waste materials including, but not limited to structures, concrete, footings, sewage disposal systems and related infrastructure, water storage and related distribution Infrastructure, roads, and other sand, plastic, gravel, pipe and cable shall be removed. All pits, cellars, and other holes will be backfilled as soon as possible after all equipment is removed to conform to surrounding terrain. All access roads to the site and associated facilities shall be closed, graded and recontoured. Culverts and any other obstructions that were part of the access road(s) shall be removed. Upon closure of a camp facility, wastewater tanks shall be completely pumped out and either crushed in place, punctured and filled with inert material or removed. Any waste material pumped from a wastewater tank or waste debris from tank removal must be disposed of at an approved facility that is permitted by CDPHE and/or Garfield County to receive said wastes. Materials may not be burned or buried (other than JSDS) on the premises. All disturbed areas affected by temporary employee housing or subsequent operations shall be reclaimed as early and as nearly as practicable to their original condition and shall be maintained to control dust, weeds and minimize erosion. As to crop lands, if subsidence occurs in such areas additional topsoil shall be added to the depression and the land shall be re- leveled as close to its original contour as practicable. Reclamation shall occur no later than three (3) months after the Special Use Permit for Temporary Employee Housing expires or is revoked unless the Director or -14 - SKR 598-36-BV Temporary Housing Chevron U.SA., Inc. designee extends the time period because of conditions outside the control of the applicant. Once drilling operations on the SKR 598-36-BV well pad are completed, the temporary employee housing units, potable water system and sewage system will be removed and relocated to the next drill site by Mountain West Oil Field Service and Supply. The well pad will continue to operate as an operable well site under the jurisdiction of the COGCC. Once the well pad has exhausted its productive lifespan, the well pad will be reclaimed according to COGCC specifications. b. All areas compacted by temporary employee housing and subsequent operations shall be cross-ripped. On crop land, such compaction alleviation operations shall be undertaken when the soil moisture at the time of ripping is below thirty-fie percent (35%) of field capacity. Ripping shall be undertaken to a depth of eighteen (18) inches unless, and to the extent, bedrock is encountered at a shallower depth. All areas impacted by the temporary employee housing and subsequent operations will be located on the COGCC-approved SKR 598-36-BV well pad. Once the pad is drilled, it will remain an operable well site under the jurisdiction of the COGCC. Once the well pad has exhausted its productive lifespan, the well pad will be reclaimed according to COGCC specifications. c. When a temporary employee housing site is removed, all disturbed areas will be restored and revegetated as soon as practicable. For disturbed areas not regulated by the Colorado Oil and Gas Conservation Commission, the following regulations will apply: All areas impacted by the temporary employee housing and subsequent operations will be located on the COGCC-approved SKR 598-36-BV well pad. Once the pad is drilled, it will remain an operable well site under the jurisdiction of the COGCC. Once the well pad has exhausted its productive lifespan, the well pad will be reclaimed according to COGCC specifications. (I) Revegetation of crop lands. All segregated soil horizons removed from crop lands shall be replaced to the original relative positions and contour, and shall be tilled adequately to re-establish a proper seedbed. The area shall be treated if necessary and practicable to prevent invasion of undesirable species and noxious weeds, and to control erosion. Any perennial forage crops that were present before disturbance shall he reestablished. -15 - SKR 598-36-BV Temporary Housing Chevron U.S.A., Inc. The proposed temporary employee housing site is not located on crop land. Weed management will be conducted according to the Integrated Vegetation and Noxious Weed Management Plan for this site. Erosion control measures will be implemented according to the Skinner Ridge Stormwater Management Plan. (2) Revegetation of non-crop lands. All segregated soils horizons removed from non- crop lands shall be replaced to their original relative positions and contour as near as practicable to achieve erosion control and long-term stability, and shall be tilled adequately in order to establish a proper seedbed. The disturbed area then shall be reseeded in the first favorable season. Reseeding with species consistent with the adjacent plant community is encouraged. In the absence of an agreement between the applicant and the affected surface owner as to what seed mix should be used, the applicant shall consult with a representative of the local soil conservation district to determine the proper seed mix to use in revegetating the disturbed area. All areas impacted by the temporary employee housing and subsequent operations will be located on the COGCC-approved SKR 598-36-BV well pad. Once the pad is drilled, it will remain an operable well site under the jurisdiction of the COGCC. Once the well pad has exhausted its productive lifespan, the well pad will be reclaimed according to COGCC specifications. d. During occupation and reclamation operations, all disturbed areas shall be kept free of Garfield County and State of Colorado List A and B noxious weeds. An Integrated Vegetation and Noxious Weed Survey have been prepared by WestWater Engineering. This Survey also includes a well-developed Noxious Weed Management Plan, which Chevron, or a contractor of Chevron, will implement to control Garfield County and State of Colorado listed noxious weeds. A copy of this Survey and Plan is attached as Exhibit 12. e. Successful reclamation of the site and access road will be considered completed when: (1) On crop land, reclamation has been performed as per ll(c)(l) of this section, and observation by the Director or designee over two growing seasons has indicated no significant unrestored subsidence. The proposed temporary employee housing is not located on crop land. (2) On non-crop land, reclamation has been petformed as per ll(c)(2) of this section, and the total cover of live perennial vegetation, excluding noxious weeds, provides sufficient soils erosion control as determined by the Director through a visual appraisal The Director or designee shall consider the total cover of live perennial vegetation of adjacent or -16 - SKR 598-36-BV Temporary Housing Chevron U.S.A., Inc. nearby undisturbed land, not including overstory or tree canopy cover, having similar soils, slope and aspect of the reclaimed area. All areas impacted by the temporary employee housing and subsequent operations will be located on the COGCC-approved SKR 598-36-BV well pad. Once the pad is drilled, it will remain an operable well site under the jurisdiction of the COGCC. Once the well pad has exhausted its productive lifespan, the well pad will be reclaimed according to COGCC specifications. (3) A final reclamation inspection has been completed by the Director or designee, there are no outstanding compliance issues relating to Galfleld County rules, regulations, orders or permit conditions, and the Director or designee has notified the applicant that final reclamation has been approved. All areas impacted by the temporary employee housing and subsequent operations will be located on the COGCC-approved SKR 598-36-BV well pad. Once the pad is drilled, it will remain an operable well site under the jurisdiction of the COGCC. Once the well pad has exhausted its productive lifespan, the well pad will be reclaimed according to COGCC specifications. f. Specifically as to revegetation, the applicant shall provide security for revegetation of disturbed areas in amount and in accordance with a plan approved by the Galfleld County Vegetation Management Department. The security shall be held by Garfield County until vegetation has been successfully reestablished according to the standards in the Garfield County Vegetation Management Plan adopted by Resolution No. 2002-94, as amended. All areas impacted by the temporary employee housing and subsequent operations will be located on the COGCC-approved SKR 598-36-BV well pad. Once the pad is drilled, it will remain an operable well site under the jurisdiction of the COGCC. Revegetation security, therefore, rests with the COGCC. g. Specifically as to reclamation, the applicant shall provide security for reclamation of disturbed areas in amount and in accordance with a plan approved by the Galfleld County Planning Department. The security shall be held by Galfleld County until reclamation has been successfully completed per Section 11 within this Section 5.02.21. -17 - SKR 598-36-BV Temporary Housing Chevron U.S.A., Inc. All areas impacted by the temporary employee housing and subsequent operations will be located on the COGCC-approved SKR 598-36-BV well pad. Once the pad is drilled, it will remain an operable well site under the jurisdiction of the COGCC. Reclamation security, therefore, rests with the COGCC. JO.

Dahlgren Deputy County Attorney Garfield County Attorney's Office 108 8th Street, Suite 219 Glenwood Springs, CO 81601 Re: Cltevron 's Title to tlte 54,000 acre "Y Lot" Dear Ms. Dahlgren, James S. Talbot Senior Counsel Law Department North America Exploration and Production Company 11111 S. Wilcrest #N2006 Houston, Texas 77099-4397 Tel 281-561-3536 Fax 281-561-3515 jtalbot@chevron.com Following up on our frequent discussions on the captioned topic and your letter of February 11, 2008 I will attempt in this letter to explain why I am 99% certain that Chevron has good title to the entire Y Lot, but despite that high degree of certainty can't provide you with a sworn statement to that effect. The basis for my belief in Chevron's having good title to the entire Y Lot starts with the Garfield County Assessors Records, which records are based on the Deed Records on file in Garfield County, which show that Chevron is the owner of the entire Y Lot. While I acknowledge that the Assessors Records may not be quite as reliable as the Deed Records they are nevertheless official records and they show that Chevron, or its predecessors have owned the Y lot for many decades and that Chevron has paid taxes on the entire Y Lot over those decades. Backing up the accuracy of those records is the fact that our on site ranch manager, Mr. Craig Tysse, is unaware of any third party claims to the Y lot acreage that put a cloud on our title to any portion of the entire lot. Finally my certainty about our title is based on my personal review of abstracts and title opinions covering portions of the Y lot all of which demonstrate good title to the sections or pieces reviewed. Over the past year I have had the opportunity to do in depth reviews of portions of the Y Lot to determine if their were problems with our title and each time I have done so I have been able to confirm title to the extent that I was able, or would be able, to provide sworn testimony as to Chevron's ownership of the particular portion of the Y Lot which was the subject of my review. While I would like to be able to provide you with a sworn declaration, either my own or outside counsels, stating that Chevron owns the entire Y Lot I cannot do so, despite my 99% certainty that such is the case, because I do not have abstracts (At least not abstracts which are up to date.) or title opinions for large portions of the Y Lot. I have discussed this with Lee Parker, Chevron's lead land Representative for the area, and he has advised me that he estimates it would take up to two years to obtain abstracts for the all the parcels for which we don't have current abstracts and to have those abstracts examined. While I Ms. Carolyn M. Dahlgren February 11, 2008 Page2 can tell you I am 99% certain of our title based on the information cited herein neither I nor our outside counsel can give a sworn statement that based on a thorough examination we have concluded that Chevron owns title to each and every acre in the entire Y Lot -we can't do so without examining current abstracts, which don't exist for the whole of the Y Lot. Part of the problem in this case stems from the manner by which Chevron acquired title. Chevron, or its predecessors, began acquiring parcels of land in Garfield County at least as early as the 1940's. Over many decades, in over a hundred separate transactions, Chevron and its predecessors, or entities it or they later acquired by merger or acquisition, put together what is shown on the Assessor's records as the Y Lot. We have scores of Deeds granted over many decades going into companies which were acquired by or merged with Chevron or entities which Chevron merged with or acquired. As you are aware I have provided detailed explanations as to how Chevron acquired title to a particular tract which forms part of the whole Y Lot. Each title I have examined records regarding one of these individual tracts I have been able to trace title into Chevron, however these examinations are more in the nature of spot checks on title as I don't have adequate abstracts on many of the individual tracts on which to base a sworn statement. As you are aware I, or outside counsel for Chevron, have been able to explain in great detail and under oath just how Chevron acquired title to each parcel for which we have submitted a permit application. Our applications include Deeds and an explanation of our title to the individual tract on which we are seeking to conduct operations. The tracts typically compose a half section or more on which all the operations for which the permit is sought will be conducted. These sworn statements are made only after conducting a very thorough review of our records including but not limited to abstracts. I do not conduct these reviews lightly and don't assert we have title unless I am very sure that I have looked at the abstracts and understand and can explain just why it is I assert Chevron has good title to the tract. While I can make no such absolute assertion as to the entire Y Lot I can say, based on the Assessor's Records, my discussions with Mr Tysse, the dozen or more title opinions I have examined, the numerous abstracts I have reviewed, and the corporate records I have examined that I am 99% certain that Chevron has good title to the whole of the Y Lot. Chevron's Land Department is working diligently to secure current abstracts and title opinions for the entire Y Lot and when those are in hand, hopefully sometime in 2010, I will be able to provide swore statements as to our good title to the whole of the Y Lot. Until that time I ask that the County rely on the detailed information I am able to provide as to Chevron's title to the tract on which all of the operations covered in the permit will be performed. That detailed information, backed by swore statements as to title on the tract, and the· information cited herein including the Garfield County's Assessors Records is good evidence of our title to the whole of the Y Lot and I request you accept it until such time we have completed our title review of the whole of the Y Lot.

Talbot, Sr. Counsel Chevron North America Exploration and Production 11111 S. Wilcrest #N2206 Houston, TX 77099 Via Regular Mail & E-Mail: jtalbot@chevron.com RE: Skinner Ridge 598-25-CV and On-Going Land Use Applications for Chevron and CUSA's Surface Tenants Dear Mr. Talbot: I have completed my initial legal review of ownership and noticing documentation for Chevron U.S.A.' s ("Chevron" or "CUSA")Skinner Ridge 598-25-CV ("25-CV")temporary housing Special Use Permit application. Chevron, as promised, provided: 1. a map, based on the Garfield County Assessor's Office Tax Parcel Map Series, showing Assessor's Parcel No. 2137-153-00-009 (in which 25-CV is to be located)and all other contiguous land held in the name of "Chevron USA", constituting one "Y" shaped,54,000+ acre"lot"under Garfield County's Zoning Resolution ("Y" or "lot") . The lot is, thus, "the property that is the subject of the hearing" under Colorado's Notification of Surface Development statute, §§24- 65. 5-103 and 103.3 (1) (a), C.R.S. , as amended. 2. identification on the map of surface owners within 200 feet of the boundary of the Y, by owner name and Assessor Parcel Number. 3. identification of severed minerals and royalty interests "in" the lot, shown on the map by notation including owner name, per cent share (when applicable) and separate Assessor's Parcel Numbers, if available. If there is no mineral notation, we are assuming Chevron owns the minerals. (I have not located a reference to any lease rights on the map; but, I understand from the information provided at the BOCC hearing on the earlier 598-25- AV application that Williams owns lease rights in Assessor's Parcel No. 2137-153-00-009.) James S. Talbot, Sr. Counsel Chevron USA February 8, 2008 Page 2 4. an Affidavit of Sur.face Ownership regarding Section 25, T5S, R98 W, 6th PM, a portion of 2137-153-00-009, in which 25 CV is to be located. (Thus, we will need the same waiver from Williams, referred to above, or proof that Williams, as a mineral lessee, has been notified of the hearing on the Special Use Permit for 25-CV.) 5. a 5-page list of surface owners within 200 feet of the boundary of the "Y" and severed mineral and royalty interest owners in the "Y". The 25-CV application does not contain back up deeds and/or US Patents for the entire lot. This is consistent with your letter and e-mail, dated November 13 and December 3, 2007 respectively, regarding: (1) title issues, (2) corporate mergers,. (3) the difficulty of providing proof of ownership for .the lot, and (4) the relative simplicity of providing proof of ownership for the multiple parcels, within the lot, upon which facilities under land use review are located. I understand from your February 4, 2008 "follow-up" e-mail that you are not in a position to provide a sworn Declaration of "good title" to the lot. Can you, instead, formalize that e mail on Chevron letterhead and allow the letter to be a part of the current 25-CV application and future Garfield County permit application packets filed by Chevron and its surface tenants? As we have discussed, proof of ownership is usually based upon a recorded deed (or deeds), or in some instances a current Title Commitment, showing ownership of the "subject lot", no matter the size, in the applicant land owner. However, based upon the BOCC' s factual findings regarding "adequate" proof of ownership and notice in recent hearings; I believe that such a letter from you, as Corporate Counsel, along with: (1) the map; (2) list of noticed surface and mineral owners, including Assessor Parcel Numbers; (3) the back-up documents for land, including US Patents for deeded un- pa tented mining claims, and minerals associated with the "tract" upon which the facility is located; and (3) the associated corporate merger documents, unless specifically referred to in your letter, would in most instances make an adequate ownership and noticing application packet. James s. Talbot, Sr. Counsel Chevron USA February 8, 2008 Page 3 Once completed, and updated in a timely manner by local Chevron representatives to show changes in mineral and surface notations, the packet could be copied for each Chevron application and the applications of Chevron's surface tenants, such as PDC and Marathon. Needless to say, the frequency with which Garfield County's real estate records are checked for changes in ownership and the method by which Chevron disseminates updated information to surface tenants are matters of internal corporate policy. However, as you know, before the hearing is opened the attorney for the BOCC asks the applicant when the County's real estate records were last checked. Title policies more than one year old at the time of hearing have been deemed inadequate to prove up ownership in the applicant land owner. Noticing information, not updated within three (3)months of a hearing, has been deemed inadequate to confer jurisdiction and allow opening of a quasi-judicial hearing before the BOCC. This is a long letter, but I also want to respond to the "conflict of laws" issue discussed in your November 13, 2007 letter. I did not mean to infer that CUSA's mergers in Delaware and Pennsylvania were subject to Colorado law, only that CUSA is subject to the Secretary of State's filing requirements for foreign corporations, detailed in the Colorado Corporations and Associations Act (Title 7, Article 90, Part 800) and to the requirements of Colorado's conveyancing statutes in Title 38. Such . statutes, as you know, deal with evidence of entity existence and authority to affect title to real property. I referred to §38-30-144 in my letter to EnCana, dated June, 2007 and copied to Chevron in August of 07. Since writing that letter, I have been unable to discern the meaning of the §38-30- 144 (3) (h), statutory requirement that foreign corporations record a "Certificate of Authority" in the Clerk and Recorder's records. As it turns out, the Secretary of State does not issue such a certfficate. The document showing authority to do business in Colorado, under current law, is the corporation's "application for authority"stamped by the Secretary of State as "filed" I "accepted" by the SOS. I have spoken with local corporate attorneys and title professionals who also find the statutory requirement unintelligible. The practice, despite the language of the statute, seems to be to record a "Statement of Authority" (§38-30-172) if and when needed, ·and, otherwise, to do what Chevron has done, i.e., file the "foreign" Certificate(s) of Merger to show Chevron as the surviving entity and thus "record" owner of the real estate. James S. Talbot, Sr. Counsel Chevron USA February' 8, 2008 Page 4 Thank you for your continued attention to the ownership and noticing issues involved in CUSA's land use applications in Garfield County. cc Julie Justus, Chevron Sincerely, fr7.~a/L'.

Dear Mr. Jarmin: MldContlnent/ Alaska SBU Chevron North America Exploration and Production Company a division of Chevron U.S.A.

Questions about this authorization should be directed to the Chevron Piceance Operations Managet·, Michael De Berry, (970)257-6005. Thank you, ,,.,, ~ f .:r .<-<! .......,_.. Michael DeBerry Chevron Piceancc Operations Manager cc: Julie Justus Timothy Barrett Sean Norris Traffic Estimates The temporary employee housing facility will be on Chevron's SKR 598-26-AV well pad, located approximately 20 miles northwest of De Beque. The site is accessible via County Road 204 north from De Beque to County Road 211. County Road 211 continues north for several miles before terminating into the private road that accesses Chevron's property. The SKR 598-26-AV is located directly off of this private road, approximately three miles north of the termination point of County Road 211. Currently, there is not sufficient housing in De Beque and the surrounding area to accommodate oil and gas operations in the area, and the driving time from towns with available housing ranges from one to two hours plus, each way, depending on weather conditions. The drilling crew and all of the support personnel will be working a 12-hour-on, 12-hour-off shift. Chevron is proposing the SKR 598-26- AV temporary housing facility to reduce traffic on county roads out of concern and respect for the safety of employees and the community Chevron contracted a traffic count in September, 2006 to analyze current traffic numbers (see attached document). Three counters were placed: one on County Road 204, just north of the County line at Mesa County Road X1/2; one on County Road 204, just north of the intersection with County Road 213; and one on County Road 211, just north of the intersection with County Road 211. The bulk of the traffic (87%) currently turns right on Logan's Road, or further up on CR 213, which are routes to other operator's sites. The remaining traffic volume shown in the study branches at the intersection of County Road 204 and County Road 211, with nine percent traveling right on CR 211 in the direction of Chevron's property, and four percent turning left and continuing on CR 204. Overall, the temporary housing facility is intended to significantly reduce traffic on County Roads 204 and 211 by eliminating a substantial amount of worker/commuter traffic. The SKR 598-26-AV temporary employee housing is designed and expected to house 20 to 24 Chevron employees at a time. It is anticipated that the personal vehicles on-site at the temporary housing facility may number between 15 and 20 at any time. Although, employees will be allowed to have their personal vehicles on-site, unnecessary personal vehicle use will be discouraged and car-pooling will be encouraged whenever possible. Therefore, it is expected that the SKR 598-26-AV temporary housing facility will eliminate approximately 20 commuter round-trips per day. Accessory traffic associated with the SKR 598-26-AV temporary housing facility is expected to be as follows: Source Type of Vehicle Number of Round-trips Initial delivery of buildings Heavy Hauling Truck 10 round-trips total and facilities Potable water deliverv Water Truck 1 round-trio oer week Drinkina water service Deliverv Truck 1 round-trio oer week Sewaae service Sewaae Truck 1 round-trio oer week Trash Trash Truck 1 round-trio oer week Removal of buildings and Heavy Hauling Truck 10 round-trips total facilities All roads used to access the SKR 598-26-AV site (CR 204, CR 211, Chevron's private road) are designed and maintained to provide safe and adequate access to the anticipated types and amounts of traffic associated with oil and gas development, specifically the temporary employee housing facility.

This SWMP addresses constrnction activities associated with development of the natural gas resources for Chevron U.S.A., Inc. in the Ski1mer Ridge area. This SWMP is intended to be updated as necessary to address planned developments, new disturbances, and other changes needed to manage storm water and protect surface water quality. A copy of this permit can be found in Appendix A. This field-wide SWMP was prepared to address storm water management practices at areas disturbed by construction and drilling activities associated with natural gas development within Skinner Ridge Piceance Basin Field Operations. This SWMP is intended to be revised as necessary to address planned developments, 11ew disturbances, and other changes needed to manage st01m water and protect surface water quality. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the U.S. from any point source be regulated by NPDES permits. In November 1990 the EPA published final regulations that established application requirements for storm water associated with constrnction activity for soil disturbances of 5 acres or more be regulated as an industrial activity and covered by an NPDES pe1mit. In December 1999 the EPA published final Phase II NPDES regulations that established application requirements for sto1m water associated with constrnction activity for soil disturbances to be regulated as an industrial activity and covered by an NPDES pe1mit. These regulations became effective July 1, 2002. On June 30, 2005, Colorado storm water regulations went into effect to require Colorado Discharge Permit System (CPDS) permits for storm water discharges from constrnction activities for small (I to 5 acre disturbance) oil and gas activities. Federal permit coverage for these discharges was conditionally exempted from the Federal Clean Water Act by the 2005 Federal Energy Bill. On February I, 2006, the CDPHE issued a letter clarifying that the CDPHE Water Quality Control Commission decided to maintain the existing requirements for storm water permitting for oil and gas construction sites of I to 5 acres. Construction pem1its are required for oil and gas activities that disturb 1 or more acres dming the life of the project or are pait of a larger common plan of development. CDPHE considers a common plan of oil and gas development to mean development of Page 1 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. several well pads and/or related infrastructure in a contiguous area either during the same time period or under a consistent plan for long-term development. 1.2 Project Description The Skinner Ridge Common Plan of Development will be located in Garfield Cow1ty, Colorado within Townships 5, 6, 7, 8 & 9 South, Ranges 97 & 98 West. The town of Debeque, Colorado is the nearest population center. The Skim1er Ridge area is located approximately 14 miles north of DeBeque (Figure 1). The current drilling and development plan includes pad construction, access road improvement/construction, pit construction, installation of associated facilities, well drilling, well completion, well testing and pipeline construction. The area of disturbance including the natmal gas well pads, the access roads and gathering system pipeline will be 3 70+ acres. Disturbance beyond five years will require re-evaluation. 1.3 Project Owner and Ope1·ator The prope11y owner and operator is Chevron U.S.A., Inc.

Mr. Cavazos can be contacted at: Phone: (218) 561-3664 Chevron will be in charge of all aspects of the property and this project. Contractor(s) will perform the actual construction and drilling, but all work will be supervised by Chevron and all decisions will be made by Chevron. Page2 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. 2.0 CONSTRUCTION SITE DESCRIPTION The following sections describe the site locations and provide a description of the construction areas. Runoff characteristics of these areas are also described. 2.1 Site Location and Construction Arca Description The Skilmer Ridge project area will be located in Garfield County, Colorado withit1 Townships 5, 6, 7, 8 & 9 South, Ranges 97 & 98 West The Skinner Ridge project area will be constructed using conventional cut and fill eartl1111oving techniques. Typically, the working pad surface may have dimension of approximately 200 feet by 400 feet. Each pad may have a reserve pit that is approximately 60 feet by 250 feet. Specific pad dimensions vary depending on the plam1ed drill rig, number of wells to be drilled from each pad, and local conditions. Reserve pits will be used during activities to contain drilling fluids and cuttings. Specific pad dimensions vary depending on the planned drill rig, number of wells to be drilled from each pad, and local terrain conditions. The reserve pits will be designed, constructed, and reclaimed according to Colorado Oil and Gas Conservation Commission (COGCC) requirements. In areas that are disturbed by well construction, topsoil will be stripped and stockpiled near the site. Soil materials will be managed so that erosion and sediment transport are minimized. Nearby drainages will be protected by appropriate measures. The well pad will be graded to drain the pad surface to the reserve pit and to direct rnnoff from surrounding areas away from the well pad and reserve pit. If the well is not productive, it will be plugged according to COGCC rules and the pad area reclaimed to approximate pre-construction contours. Reclamation and final stabilization will be conducted as described in Sections 4 and 7. Skinner Ridge well pads and facilities are surrounded by the following Colorado Land Cover Classification Systems: Low Elevation Salt-Desert Scrnb/Basin Big Sagebrush Pinyon-Juniper Woodland, Mountain/Wyoming Big Sagebrush Shrubland A vegetation description for each Skilmer Ridge project area is provided in Table 1. Vegetative cover surrounding Skinner Ridge project area ranges from 60-85%. Due to regional climate conditions, lack of surface water or near surface ground water, and well pad constrnction design, construction dewatering is not expected for Skitmer Ridge development activities. Page3 SKINNERRJDGE SWMP CHEVRON U.S.A., INC. 2.2 Schedule of Construction Activities Natural gas exploration and development activities are planned for several years. Existing and future well pads and other disturbances are included in this SWMP. For well pads that will be constrncted, Best Management Practices (BMPs) will be installed prior to, during, and immediately following constrnction. Development of the natural gas resource and construction of necessary improvements on this prope1ty will likely continue for five years or greater. The development of natural gas wells is generally accomplished in three distinct work phases. The first phase is the Development (Constrnction/Drilling/Completion/Initial Reclamation), the second phase is the Production (Operation/Maintenance), and the third phase is the Abandonment and Final Reclamation. Each work phase is briefly discussed below. Development (Construction/Drilling/Completion/Initial Reclamation) The Development phase includes the following activities; road and well pad construction, well drilling, well completion, gas line installation, and pad area reclamation. The well pad will be constructed and graded with a gentle slope to drain surface water to the reserve pit. Gas pipelines are installed during this phase of work. Initial pad reclamation is accomplished by backfilling the reserve pit, contouring disturbed soils to confonn with the surrounding te1rnin, replacing stockpiled top soil, seeding of disturbed soil areas in order to reestablish a cover vegetation, and construction of erosion and sediment control strnctures. The completion of a well (gas production) generally triggers a one-year time period in which the reclamation phase of work should be completed. A listing of the revegetation seed mixtures are provided in Table 2. Production (Operation/Maintenance) The production phase includes the operation and maintenance activities during natural gas production. Typical well pad equipment includes a wellhead, a separation unit and one to several 300-barrel capacity aboveground storage tanks (ASTs) containing condensate and or produced water. Smaller sized ASTs may contain lube oil, methanol, and triethylene glycol. If the exploratory holes yield economically viable natural gas resources; additional gas well drilling will proceed. Reclamation activities during this phase include maintenance of revegetated areas and maintenance of the erosion and sediment control structures. Natural gas wells in the Skinner Ridge area are projected to produce for approximately 20 to 30 years. Interim and Final Reclamation The pad area will be reclaimed by contouring disturbed soils to conform to the surrounding terrain, by replacing the stockpiled top soil, by seeding of disturbed soil Page4 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. areas in order to reestablish cover vegetation, and by construction of ernsion and sediment contrnl structures as needed. Once the well is completed and brnught into prnduction it will operate as an unmanned facility twenty-four hours per day, seven days per week, and 365 day a year. Chevron personnel or contract personnel will visit the site daily or at a minimum one per week. Once stabilization is achieved, defined as uniform vegetative cover established with a density of at least 70 percent of pre-disturbance levels, a well pad may be removed from this SWMP for sediment controls. However, if petroleum hydrocarbons or other chemicals impact storm water as a result of industrial activities onsite, the impacted stormwater will be addressed by following a spill prevention control and countermeasures (SPCC) plan. 2.3 Runoff Characteristics Runoff characteristics are based on site topography, soil type, and soil/vegetative cover. According to the NCRS, soils for the Skinner Ridge project area consist of the following soil types: l. Biedsaw-Sunup gravelly loams, 10 to 40% slopes -is on side slopes of mountains and ridges. Native vegetation is mainly juniper, sagebrush, shadscale saltbrush, greasewood, ephedra, yucca, and Indian rice grass. Elevation is 5, 100 to 6,600 feet. Biedsaw soil is deep and well drained. Permeability is slow and water capacity is high. Runoff is rapid and water ernsion is severe. Sunup soil is shallow and well drnined. Pe1meability is moderate and water capacity is very low. Runoff is rapid and water erosion is severe. 2. Cunrnlic Haploborolls, 1 to 3% slopes -are on flood plains. Vegetation is narrowleaf, cottonwoods, maples, willows, grasses, and forbs. Elevation is 5,800 to 7,400 feet. The soil is deep and is well drained to poorly drained. Permeability is moderate to moderately slow and water capacity is low to high. Runoff is slow and water erosion is slight. 3. Grobutte very channery loam, 30 to 60% slopes -is on steep hills and mountainsides. Native vegetation is shrubs and grass. Elevation is 6,000 to 8,000 feet. The soil is deep and well drained. Pe1meability is moderately rapid and water capacity is low. Runoff is rapid and water erosion is very severe. 4. Happle very channery sandy loam, 12 to 25% slopes -is on alluvial-colluvial fans and toes lopes. The soil is deep and well drained. Native vegetation is sagebrush, grasses, and forbs. Elevation is 5,400 to 6,200 feet. Penneability is moderate and water capacity is low. Runoff is medium and water erosion is severe. 5. Happle-Rock outcrop association, 25 to 65% slopes-is on side slopes and canyon rims. The soil is deep and well drained. Native vegetation is sagebrush, grass, and forbs. Page 5 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. Elevation is 6,200 to 7,200 feet. Penneability is moderate and water capacity is low. Runoff is rapid and water erosion is severe. 6. Tosca channery loam, 25 to 80% slopes -is on mountah1 side slopes and footslopes. The soil is deep and well drained. Native vegetation is serviceben'Y, Gambel's oak, snowbell'y, and grasses. Elevation is 6,200 to 8,500 feet. Permeability is moderate and water capacity is low. Runoff is rapid and water erosion is very severe. The pre-disturbance percent ground cover ranges from 60 to 85 percent. A vegetation description for each Skinner Ridge project area is provided in Table 1. Possible receiving waters include unnamed tributaries of Tom Creek, Deer Park Gulch, Clear Creek, Conn Creek, Brush Creek, Roan Creek, West Parachute Creek, Parachute Creek and ultimately the Colorado River. Page 6 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. 3.0 POTENTIAL POLLUTION SOURCES Potential pollution· sources associated with construction sites and natural gas development include: Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; Sediment discharges from vehicle tracking; Leakage of fuels and lubricants from equipment and spills from fueling; Trash and debris from clearing activities, construction materials, and workers; Leakage or spills from storage tanks and process equipment associated with the natural gas development. The most common source of pollution from pad and access road construction is sediment, which can be canied away from the work site with storm water runoff and impact the water quality of a receiving stream. Clearing, grading, and othe1wise altering previously undisturbed land can increase the rate of soil erosion over pre-disturbance rates. Refined petroleum products can also be potential storm water pollutants. These products are used in constrnction activities to power or lubricate equipment and include: fuel, gear oil, hydraulic oil, brake fluid, and grease. Debris from laydown areas, residue from equipment cleaning and maintenance, and solid waste generated from land clearing operations and human activity (trees, brush, paper, trash, etc.) present other potential pollution sources within the construction site. Additionally, one or more facilities may contain construction supplies such as various sized pipe, culve1ts, metal sheds, empty tanks, drums and vessels, fencing and stairs. Constrnction of new production facilities may require the use of concrete. Concrete wash out waters will be managed to prevent them from reaching waters of the state. Typically concrete wash out waters will be diverted to the well pad flare pit or other type of earthen impoundment to capture and evaporate wash out water. Loading and unloading of condensate and produced water from above ground storage tanks are common and regular activities within the Skinner Ridge project area. Spills and or tank over flows can contaminate sto1111 water runoff. Magnesium chloride solution or other chemical dust suppressants may be applied during the summer to unpaved roads to order to reduce fugitive dust generation. Magnesium chloride solution is used in the winter for roadway deicing and in the summer for dust suppression by county and state governn1ent entities. The solution is typically delivered to the site by contractors in DOT approved tanker trailers and generally is quickly applied to the road surface. Occasionally, depending on work site conditions, the tanker trailers Page 7 f I SKINNER RIDGE SWMP CHEVRON U.S.A., INC. may be staged along the road until ready for application (typically no longer than overnight). Spills or leaks from potential sources are described in the SPCC plan. Response to certain events may require specialized training due to health and safety concerns. For a list of down-hole chemicals used during development activities please refer to Appendix B. Page 8 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. 4.0 DESCRIPTION OF CONTROL MEASURES The following sections provide a description of BMPs, including physical structures, employed to prevent soil erosion, work practices and managerial controls used to prevent storm water impacts, and fuels, chemicals, and materials handling practices. The use of a combination of physical BMPs, good work practices, and storing fuels, chemicals, and materials in covered and isolated areas will prevent storm water impacts. 4.1 Soil Erosion and Sediment Controls The objective of erosion and sediment controls is to minimize the release of sediments to stonn water runoff. This can be accomplished tiu'Ol1gh the use of strnctural and/or nonstructural controls. This section describes physical erosion and sediment controls to be used at active construction sites to minimize possible sediment impacts to storm water rnnoff. For BMP installation details refer to Appendix C and selection guidelines are listed in Figure 2. Berms A berm is a ridge of compacted soil located at the top or base of a sloping disturbed area to contain or divert surface rnnoff. Where used, soil be1ms shall be constructed of soil with sufficient fines to minimize flow through the benn. The purpose of a berm is to control runoff velocity, divert onsite surface rnnoff to a sediment trapping or filtration device and/or dive1t clean water away from disturbed areas. Check Dams Check dams are small, temporary dams constructed across a diversion or roadside ditch. Check dams can be constrncted using gravel, rock, gravel bags, geo-ridges, eaith with erosion control blanketing, straw bales, or wattles and are used to slow the velocity of concentrated flow in a channel. As a secondary function, check dams can also be used to catch sediment from the channel itself or from the contributing drainage area as storm water runoff flows through or over the structure. Culverts Culve1ts are typically used to move ditch water under the road or to direct stream flow under the access road. Culve1ts are typically constrncted out of concrete, steel, aluminum, or plastic pipe. Where used, culverts should have inlet and outlet protection features to minimize erosion such as placing a non-woven textile material under rip rap at each end of the culvert. Page9 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. Diversion Permanent diversion berms and stmctures control storm water mnoff by using a channel · and an earthen ridge to prevent sediment laden stor111 runoff from leaving the construction site, well pad or other disturbed area, to prevent flows from eroding slopes and to direct sedi111ent laden flows to a trapping device. Diversions are 111ost often constmcted of eaithen materials with vegetative cover and are best used with channel linings such as vegetation or matting. Diversions are typically used wherever the direction and velocity of mnoff from up slope areas need to be controlled. A good example would be diverting upgradient surface mnoff away from a well pad. Channels and be1ms 111ust be designed to manage peak storm flow and must be stabilized to prevent erosion of the channels. Drainage Dip Drainage dips intercept and remove surface water from the access roads, pads, facilities, pipelines, and roadside ditches (before the combination of water volume and velocity begin to erode.) Drainage dips ai·e constructed diagonally across the flow of the surface water and will pass slow traffic while dispersing surface water. Erosion Control Blanket Erosion control blankets, and turf reinforcement mats (TRM), are porous fabrics and are manufactured by weaving or bonding fibers made from organic or synthetic materials. Erosion control blankets are installed on steep slopes, over bem1s, or in cham1els to prevent erosion until final vegetation is established. The erosion control blankets can also be used as separators or to aid in plai1t growth. Filter Berm A filter berm is temporary ridge made up of natural materials that already occur on the project site. Bmsh fllter be1ms use small tree branches, root mats, grass, leaves, stone or other debris or material naturally available or left over from the site clearing and grubbing. Rock filter berms use site gravel, stone, or rock. Both types of filter be1ms are placed along a level contour to slow, filter, and divert flow and act as an efficient form of sediment control. Georidge GeoRidge® is a pe1meable ditch be1m designed for erosion and sediment control. The use of GeoRidge® reduces flow velocities and provides a smoother water flow resulting in less erosional energy, and thus minimizing the problem of downstreain sediment. Gravel Surfacing Gravel surfacing may be used to cover soil in areas of high traffic source as roads, facility areas, and areas near the well heads. Gravel surfacing forms a layer that protects and minimizes soil erosion and vehicle soil tracking. Page 10 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. Land Grading Grading involves reshaping the ground surface to planned grades as determined by an engineeritig survey, evaluation, and layout. Grading provides more suitable topography for well pads, pipelines, facilities and access roads and helps to contro I surface runoff, soil erosion, and sedimentation during and after construction in these areas. Grading also includes road crowning and sloping to properly route mnoff off the access roads. Level Spreader A level spreader is a BMP used to prevent erosion and to improve infiltration by spreading concentrated sto1m water runoff evenly over the ground as shallow sheet flow instead of through channels. It usually involves a depression in the soil surface that disperses flow onto a flatter area across a slight slope and then releases the flow onto level vegetated areas. This reduces flow speed and increases infiltration and promotes evaporation. Mulching Mulching is a temporary erosion control practice in which materials such as grass, straw, hay, wood fibers or wood chips are placed on exposed or recently planted soil surfaces. Mulching stabilizes soils by minimizing rainfall impact and reducing storm water runoff velocity. When mulching is used in combination with seeding, surface soils retain moisture, promote seed ge1mination and help insulate roots from extremes temperatures. Retaining Wall Retaining walls are structures that are used to stabilize and hold soil in place, gain space on roadways or well pads, or to keep soil contained within a site boundary. This BMP can be constructed with rock, boulders, and/or cement blocks. Revegetation Revegetation involves planting seed to establish a vegetative cover on disturbed areas. Revegetation reduces erosion and sedimentation by stabilizing disturbed areas in a manner that is economical and adaptable to site conditions. It also reduces runoff volumes by increasing water percolation into the soil, binds soil with roots, and protects soil from wind erosion. The pemianent seed mix, rate, and application method is provided on Table 2. Riprap Riprap is a permanent, erosion-resistant layer made of stones, rock, or boulders. It is intended to stabilize areas subject to erosion and protect against scour of the soil caused by concentrated, high velocity flows. Page 11 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. Roadside Ditches and Turnouts Roadside ditches are channels constrncted parallel to roads. The ditches convey concentrated runoff of surface water from roads and surrounding areas to ·a stabilized outlet. Turnouts are used to effectively remove run-off water from the roadside ditch into well-stabilized areas before it reaches a wate1way. Sediment Trap Sediment traps are intended to intercept, trap, and retain sediment from runoff while allowing detained runoff to slowly drain, infiltrate, or both. They are usually installed in a drainage way or other point of discharge from a disturbed area. This BMP is formed by excavating below grade and/or constructing an earthen embankment with a protected spillway to slow the release of runoff. Silt Fence Silt fences are used as temporary perimeter control strncture that is designed to slow, temporary impounds, and filters sediment laden water. Installation teclmiques and maintenance is critical to proper performance. Slope Drain Slope drains are used with eruth dikes and drainage ditches to intercept and direct surface flow away from slope areas to protect cut or fill slopes. A slope drain is applicable for any construction site where concentrated surface rnnoff can accumulate and must be conveyed down a slope in order to prevent erosion. The slope drain may be a rigid pipe such as corrugated metal, flexible conduit or a lined terrace drain with the inlet placed at the top of the slope and the outlet at the bottom of the slope. Inlets must be securely ru1chored and outlets must be stabilized with riprap. Stabilized Constrnction Entrance A stabilized construction entrance is a pad of gravel laid over filter cloth where construction traffic will be entering or leaving a constrnction site to or from a public right-of-way, street or highway. This is also referred to as vehicle tracking control. The purpose of a stabilized entrru1ce to a site is to minimize the amount of traced mud and dust that leaves the site and tracked onto county roads or state highways. As a vehicle drives over the gravel, mud and sediment are removed from the vehicle's wheels and offsite transp01t of soil is reduced. This BMP reduces erosion, tire rntting and the filter fabric separates the gravel from the soil below by minimizing the migration gravel into subsurface soil from heavy vehicle loads. A stabilized construction entrance should be used at facility ingress and egress locations. Page 12 I ' SKINNER JUDGE SWMP CHEVRON U.S.A., INC. Straw Bale Ban·ier A straw bale barrier is a sedes of entrenched and staked straw bales placed on a level contour to intercept sheet flows. The barrier reduces mnoff velocity and filters sediment laden runoff from small drainage areas of disturbed soil. This BMP may also be used to protect against erosion in small shallow drainage channels. Straw Wattles Straw wattles or rolls are intended to capture and keep sediment on slopes or in small shallow drainage channels. Straw rolls can be used to temporarily stabilize slopes by reducing soil creep, sheet and rill erosion until permanent vegetation can be established. Straw rolls will last an average of one to two years. Surface Roughening Soil surface roughening is a temporary erosion control practice often used in conjunction with grading. Soil roughening involves increasing the relief of a bare soil surface with horizontal grooves (corrugating) or tracks (tracking) using construction equipment. Slopes that are not fine graded and that are left in a roughened condition can reduce erosion, trap sediment, and prepare ground surfaces for seeding. Tel1'acing Te1Taces are made of either earthen embankments or ridge and channel systems that are properly spaced along a fill slope. Ten·aces are constructed with an adequate grade to promote drainage to a stabilized outlet. They reduce damage from erosion by collecting and redistributing surface runoff to stable outlets at slower speeds and by decreasing the distance of overland tunoff flow. They also surpass smooth slopes in holding moisture and help to minimize sediment loading of surface runoff. Vegetative Buffer Vegetative buffers are areas of either natural or established vegetation that are maintained to protect the water quality of neighboring areas. Vegetative buffers reduce st01111 water runoff velocity, prevent soil erosion, promote infiltration and act as a filter to remove sediment. Water Bar A water bar is an emthen ridge, or ridge and channel, constructed diagonally across a slope road, trail, or disturbed area. Water bars are nonnally used for drainage and erosion protection of closed, blocked, or infrequently used roads to divert st01111 water runoff and minimize erosion. Page 13 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. 4.2 Storm Water Management Controls Structural BMPs will be installed, inspected, .and maintained as needed. This SWMP will be revised as necessary to address new disturbances, construction or operation. Depending on the type and location of new facilities there may be a need for inclusion of new and different BMPs. In general, new development should be planned with consideration for storm water quality (e.g. minimize disturbed area and maximize distance from surface water drainages, as practicable). Other developments on the property, primarily existing and/or improved roads, not cmTently or specifically addressed in the SWMP will be periodically checked for erosion and drainage problems. This is especially important for access roads located within 100 feet of surface drainages or creeks. If problems are noted, they should be reported to the local contact person. Problem areas may be addressed through construction activities, but will likely need to be addressed tluough BMPs which will be added to the plan as needed. 4.3 Other Controls Waste Management and Disposal Well pad construction and drilling will generate various other wastes during the course of construction. Other wastes may include the following: Sagebrush, sluubs and trees from clearing operations; Trash and debris from construction materials and workers; Drill cuttings, drilling fluids, frac sand, completion fluids; and Sanitary sewage. Each of these wastes will be managed so as to not contribute to storm water pollution. Construction trash and debris will be collected in containers and hauled off-site for disposal in suitable landfills. Sanitary waste will be containerized in portable toilets or other storage tanks with waste materials regularly pumped and transpo1ted off-site for disposal at approved facilities. Fuels and Materials Management Petroleum products which may be present at the construction site include: gasoline, diesel fuel, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline, diesel fuel, lubricant, hydraulic, and miscellaneous oils and solvents will be stored in p01table storage tanks with secondary containment. Pollutants from petroleum products used during construction activities adhere easily to soil paiticles and other surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to a proper disposal site. Proposed soil erosion Page 14 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. and sediment control practices will aid in retention of spills or leaks. Use of secondary containment and drip pans will reduce the likelihood of spills or leaks contacting the ground. Proposed maintenance and safe storage practices will reduce the chance of petroleum products contaminating the road site. Oily wastes such as crankcase oil, cans, rags, and paper containing oils will be placed in proper receptacles and disposed of or recycled. An additional source of petroleum contamination is leaks from equipment and vehicles. Routine daily inspections will be conducted to identify leaks and initiate c011·ective actions, if needed. The local SPCC plan and or Emergency Response Plan wiJJ be activated as appropriate to manage any petroleum product spill. The following guidelines for storing and managing petroleum products will be used: All product containers will be clearly labeled. Drnms will be kept off the ground within secondary containment and stored under cover if needed. Fuel tanks will be stored within secondary containment. Lids of drummed materials will be secnrely fastened. Emergency spill response procedures will be available on-site. Spill clean up and containment materials (absorbent, shovels, etc.) wiJJ be easily accessible. Spills will be immediately cleaned up and contaminated materials wiJJ be properly stored on site until they can be disposed of in accordance with applicable regulations. Storage areas and containers will be regularly monitored for leaks and repaired or replaced as necessary. Contractors and subcontractors should be reminded about proper storage, handling and transferring of petroleum products or other hazardous materials during safety meetings. All spills and releases of exploration and production waste or produced fluid exceeding 5 ban·els (210 gallons) including those contained within unlined benns, shall be reported in writing on the COGCC Spill/Release Repott Form 19 within 10 days of discovery of the spill. All spills/releases that exceed 20 batTels (840 gallons) of exploration and production liquids/waste shall be verbally rep01ted to the COGCC at (303) 894-2100 within 24 hours of discovery. Spills or releases of any size that impact or threaten to impact any waters of the state, residence or occupied strncture, livestock or public byway, shall be verbally reported to the COGCC as soon as practical after discovery (COGCC Rule 906). If the spill may reach waters of the state (which includes surface water, ground water and dry gullies or storm sewers leading to surface water), it must also be rep01ted immediately to the Colorado Depa1tment of Public Health and Envirollt1lent (CDPHE) at 1-877-518-5608. Spills or releases of more than 25 gallons of refined petroleum crude oil products such as gasoline, diesel fuel, oil, or derivatives of mineral, animal or vegetable oil shall be Page 15 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. repotted to the state of Colorado Division of Oil and Public Safety at (303) 318-8547 within 24 hours. A hazardous substance release in any amount which enters or threate11s to enter waters of the state shall be reported to Colorado Depa1tment of Public Health & Environment (CDPHE). Other Chemicals Products Management Additional materials will be used and stored on site for use in construction. These materials will be stored appropriately and managed to minimize spills and leaks. Storage areas will be regularly inspected and any minor spills or leaks will be cleaned up inuuediately. Materials Management The construction contractor will maintain a laydown or staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will be inspected on a regular basis for spills, leaks, and potential of materials commingling with stonu water runoff. 4.4 Construction Site Housekeeping Housekeeping will consist of neat and orderly storage of materials and containerized fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at off-site, suitable facilities. If spills occur prompt cleanup is required to minimize any commingling of waste materials with stom1 water runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans will be used during routine fueling and maintenance to contain spills or leaks as needed. Any waste product from maintenance will be containerized and transpo1ted off site for disposal or recycling. All attempts will be made to minimize major equipment overhauls conducted on site. Equipment will be transported off site for major overhauls if requiTed. Cleanup of trash and discarded materials will be conducted at the end of each work day. Cleanup will consist of patrolling the road way, access areas, and other work areas to pickup trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of appropriately. Page 16 SKINNER JUDGE SWMP CHEVRON U.S.A., INC. 5.0 INSPECTION AND MAINTENANCE PROCEDURES To meet requirements of Stonn Water General Pennit inspection and maintenance of erosion and sediment controls must occur dming the construction project. Continued inspection and maintenance is required for specific strnctures after constrnction is completed. A complete list of active inspection locations, site diagrams and site specific storm water BMPs are provided in the inspection repmt book kept with the SWMP. The inspection program will include the following: 1. A trained and qualified person familiar with the SWMP and storm water controls will conduct facility inspections and complete the Storm Water Field Inspection Report fonn or a Site-Specific Storm Water Management Plan in Appendix D. 2. Inspections will cover these areas: Evidence of smface erosion for disturbed areas; Material and chemical storage areas; Best Management Practices (BMPs); Smface water diversions and downgradient areas; New access roads and ditches; and Locations where vehicles enter or exit the site. 3. Routine Inspections will occur at least once every 14 calendar days and within 24 hours after a significant precipitation or snow melt event that causes erosion; if no construction activities occurs following a storm event, post-sto1m event inspections shall be conducted prior to re-commencing constrnction activities but no later than 72 hours following the stonn event.; depending on safety concerns. 4. Permanently stabilized areas will be inspected at least once per month; depending on safety concerns. 5. A log of inspections will be completed and maintained for a minimum of three years. A copy of the SWMP will be kept at the Hiner Gate Field Office. 6. Inspections are not required for disturbed areas when snow cover exists over the entire site for an extended period as long as melting conditions do not exist. 7. Water quality will be visually assessed for all receiving streams and discharge areas during each inspection if present. 8. Disturbed areas and material storage areas that are exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. Page 17 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. 9. Check dams, wattles, and other BMPs will be inspected for evidence of deterioration, under-cutting, and build up of sediment. Sediment will be removed when it has built up one-third to one-half the height of the hay bales or wattles. I 0. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. 11. The SWMP will be modified as necessary whenever there is a change in design, constrnction or operation that changes the potential for pollutant discharge to waters of the state. 12. An inspection repo1t summarizing the scope of the inspection, the name of the person conducting the inspection, date of inspection, and observations relating to the implementation will be prepared. An inspection repo1t and Site-Specific Storm Water Management Plan are provided in Appendix D. 13. Actions taken to modify storm water control measures will be recorded with inspection repo1ts and maps and maintained with the SWMP. 14. If no deficiencies are found during the inspection, the report contains a ce1tification statement that the site is in compliance with the SWMP and the General Permit. Perso1111el performing facility inspections such as access roads, well pads or other operational facilities will record site conditions on the Storm Water Inspection Report foim or a Site-Specific Stmm Water Management Plan in Appendix D. Immediately when deficiencies are discovered, the Chevron local contact will be contacted and will direct designated subcontractors to perform BMP maintenance or replacement. Maintenance will include prompt adjustments and repairs to erosion and sediment control strnctures that are found to be perfo1ming inadequately or deteriorating. Signs of rill or gully surface erosion shall be immediately repaired. The Chevron local contact has the authority and will coordinate subcontractors to install new and or additional storm water control BMPs as needed. Page 18 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. 6.0 NON-STORM WATER DISCHARGES No non-stmm water discharges are anticipated from the project. Possible exceptions include fire prevention/suppression or dust control activities. Page 19 SKINNER RIDGE SWMP CHEVRON U.S.A., INC. 7.0 FINAL STABILIZATION Areas which have been disturbed are considered to be stabilized when a uniform vegetative cover with a density of 70 percent of the pre-disturbance levels has been established or when an equivalent permanent, physical erosion reduction method is in-place. The disturbed areas will be seeded and mulched for final stabilization. Table 2 contains approved seed mixtures and application rates provided by the Natural Resources Conservation Services (NRCS) for the Skhmer Ridge project area. Typical Pure Live Seed (PLS) application rates are recommended to be doubled if seeding is performed by hydroseed or broadcasting. Areas not used for facilities, access roads, materials storage yards, or other work areas will be stabilized with vegetation. Areas that are stabilized with vegetation will be considered to have achieved final stabilization when a uniform stand of vegetation with a density of at least 70 percent of the pre-disturbance has been established. Sprayed on mulches and other slope stabilization materials may be used in combination with seeding techniques in select areas to promote and establish surface vegetation cover. Other areas which may include facilities, access roads, materials storage yards, and other work areas will be stabilized with the use of permanent, physical erosion reduction methods which include, but are not limited to: I. Surface hardening -covering of the soil surface with hardened products such as concrete or asphalt pavement. 2. Surface covering -covering of the surface soil with strncture that inhibits contact of precipitation with the soil surface which is generally considered to be placement of a structure (building or tank) over the soil surface. 3. Gravel surfacing -gravel surfacing will be applied in areas such as access roads, materials storage yards, and other work surfaces. Some gravel may be lost due to erosion from intense precipitation events or due to vehicle traffic. Gravel surfaces will be periodically inspected to determine the need for gravel replacement. Gravel surfaces will be replaced or repaired (through grading) when inspection reveals that the gravel surface is no longer effectively covering the soil surface.

TE&\.!S AND CONDITIONS (cont.) 3) \Vinter Conditions Inspections Exclusion -Inspections are not required at sites where constn1ction activities are ten1porarily halted, sno\v cover exists over the entire site for an extended period, and melting conditions posing a risk of surface erosion do not exist. This exception is applicable m during the period where melting conditions do not exist, and applies to the routine 14-day and monthly inspections, as \vell as the post-stonn- event inspections. The following inforn1Btion must be documented in the inspection record for use of this exclusion: dates when sno\V cover occurred, date when construction activities ceased, and date melting conditions began. Inspections, as described above, are required at all other times. When site conditions make the schedule required in this section impractical, the permittee may petition the Division to grant an alternate inspection schedule. b) lnspectlon Requirements I) Inspection Scope -The construction site perimeter, all disturbed areas, n1aterial and/or waste storage areas that are exposed to precipitation, discharge locations, and locations \Vhere vehicles access the site shall be inspected for evidence of, or the potential for, pollutants leaving the construction site boundaries, entering the stonnwater drainage system, or discharging to state 'vaters. All erosion and sediment control practices identified in the S\VMP shall be evaluated to ensure that they are maintained and operating correctly. 2) Inspection Report/Records -The permittee shall keep a record of inspections. Inspection reports must identify any incidents of non-compliance with the terms and conditions of this perniit. Inspection records must be retained for three years from expiration or inactivation of permit coverage.

Best Management Practices (BMPs): schedules of activities1 prohibitions of practices, maintenance procedures, and other nianagement practices to prevent or reduce the pollution of waters of the State. BlvlPs also include treatment requirements, operating procedures, pollution prevention, and practices to control site runoff, spillage or leaks, \Vaste disposal, or drainage from material storage. 2. Dedicated asphalt plants and concrete plants: portable asphalt plants and concrete plants that are located on or adjacent to a construction site and that provide materials only to that specific construction site. 3. Finni stabilization: when all ground surface disturbing activities at the site have been completed, and uniform vegetative cover has been established \Vith an individual plant density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physica1 erosion reduction methods have been employed. For purposes of this permit, establishment of a vegetative cover capable of providing erosion conttol equivalent to pre-existing conditions at the site 'vill be considered final stabilization. 4.

S. Operator: the entity that has day-to-day supervision and control of activities occurring at the conStn1ction site. This can be the owner, the developer, the general contractor or the agent of one of these parties, in some circumstances. It is anticipated that at different phases of a construction project, different types of parties may satisfy the definition of 'operator' and that the pennit may be transferred as the roles change. 6. Outfall: a point source at the point 'vhere stormwater leaves the construction site and discharges to a receiving water or a stormwater col1ection system. 7. Part of a larger common plnn of development or sale: a contiguous area where nlultiple separate and distinct construction activities may be taking place at different times on different schedules. 8. Point source: any discernible, confined and discrete conveyance from 'vhich pollutants are or may be discharged. Point source discharges of stonnwnter result from strucrures 'vhich increase the imperviousness of the ground which acts to collect runoff, with runoff being conveyed along the resulting drainage or grading pattern. 9. PoUutant: dredged spoil, dirt, slurry, solid waste, incinerator residue, sewage, sewage sludge, garbage, trash, chemical waste, biological nutrient, biological material, radioactive material 1 heat, wrecked or discarded equipment, rock, sand, or any industrial, municipal or agriculh.lral waste. 10.

CHANGES IN THIS GENERAL PERMIT Several notable changes fi·o111 the previous General Per1nitfor Construction Activities have been incorporated into this pe1111t't. Si'g11ifica11t changes are lfsted belolv, Nu1nerous otl1er 111i11or changes were 1nade for clarification purposes only. A. A11thoritv to Discharge This section ltas been restructured to list all of the types of activities covered by this permit, and to be consistent 1vith the definition of "constn1ction activity. 11 The definition of construction activity has been expanded to provide clarification. See Part l.A.J of the permit. PARTU Pennit • Page 24 Pennit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (cont.) B. A11thorltv to Discharge -Oil and Gas Construction This section has been added, to take into account a regulatory change. The federal Energy Policy Act of 2005 exempts nearly all oil and gas construction activities from federal requiremellls 1111der the Clean Water Act's NP DES stomnvater discharge permit program. In January 2006, the Colorado Water Quality Control Com111issio11 held a hearing to determine what effects, if a11y, the cha11ge i11federal law would have upon Colorado's stornnvGter regulations. The Co1111nission deternu'ned that oil and gas construction sites in Colorado tlzat disturb one or 1nore acres a,·e still required to be covered under Colorado's stor1n1vater permilling regulations (Colorado Discharge Permit System (CDPS) regulations (5CCR 1002-61)). I11 practice, oil and gas consfnlction sites have the sa111e requiren1ents under this per111it as do other types of cons11·uct/011. Howevei; this permit coll/ains some references to the federal Clea11 Water Act; ge11erally these references are 1101 applicable to oil a11d gas co11structioi1 sites to the exte/11 that the refere11ces are limited by the federal E11ergy Policy Act of 2005. See Part 1.A.l (b) of the pen11it. C. Application Req11iren1ents The pennlt application requirements have changed slightly, i11cl11di11g the additio11 of a11 email address, if available. See Pan 1.A.4(b). The applicant 111ust be either the 01v11er and/or operator of the construction site. An operator at a construction site that is not covered by a certificatio11 held by an appropriate elltity may be held liable/or operating lvilhout the necessary permit coverage. D. Te111oorary Coverage Part lA.5(d) of the previous permit (effective July /, 2002) dealt with temporarily covering a facility under the general pennit even if a11 individual per111it is 111ore appropriate. This pe11nit section essentially duplicated the previous section (.'"e Part lA.5(c)}, and so it has been deleted. E. Reassign111ent of Pennit Coverage Procedures have been added to clari.fY the requirements for the transfer of coverage of specific portions of a pen11illed site to a second party. See Sectio11 VIII.1.3 of the rationale a11d Part J.A.8 of the permit. F. llldividual Permit Criteria This section has been modified to include situatio11s /11volving a Total Maximum Daily Load (TMDL). See Pal'/ 1.A.l I of the permit. G. Stormwater Management Plan (SWMPI The Stor11iwater Manage1nent Plan section has bee11 divided into nvo parts: Stonnlvater Manage111ent Plan (SWMP) -General Requireme/l/s, which provides the basic framework and general requireme/lls for the SWMP, and Stom1water Ma11ageme/I/ Plan (SWMP) -Contents, which specifically identifies each item that must be addressed i11 the SWMP. See Parts I.Band I.C of the pennit. H. Stonmvater Ma11agement Plqn (SWMPI -Ge11eral Requirements The SWMP Ge11eral Requiremellts section has been modified to require that the SWMP be updated in accordance with Parts l.D.5(c) and l.D.5(d) of the permit (SWMP Review!Cha11ges). This additio11al requireme11t e11s11res that the SWMP provisio11s reflect current site co11ditio11s. See Part I.B.2(c) of the pern1it. ~ I PART II Pennit -Page 25 Permit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (cont.) I. Stormwater Management Plan (SWMPJ -Contents The SWMP Contents section has been modified. Some of the clranges are limited to organization of information, which does not require modiflcatlon of an existing permittee 's current SWMP. Most of the SWMP changes involve either clarifications, refor111atti11g, or taking reco1n1nendations fro1n the Division's SWMP guide and making tlrem pennlt requirements (e.g., veMc/e tracking controls, BMP installation specifications). If an existing permittee (i.e., those with permit coverage before June 30, 2007) followed the recommendations in tire SWMP guide (Appendix A oft/ie pennlt application), then their SWMP will presumably meet the new requirements. However, for any existing permittees who did !JQ!follow the applicable SWMP guide recommendations. their SMWP must be amended to incbtde the new required items: -SWMP Administrator -Identification of potential pollutant sources -Best Manage1nenJ Practices descriptions and installation specifications, including dedicated concrete or asphalt batch plants; veilic/e tracking control; and waste management and disposal (including concrete washout activities). For existing permittees, any SWMP changes based on the change in permit requirements mus/ be completed by October I, 2007. The plan is not to be submitted to the Division unless requested, but must be available on site as outlined in Part I.D.5(b) of the pennlt. The BMP requirement clarifications included in this renewed permit In no way Imply that adequate BMPs to address all pollutant sources at a permitted site were not required in previous permits. The revised require111ents are intended only to better clarify SWMP content require1t1ents and provide improved direction to per1nittees. Tire SWMP changes are listed below. All new applicants (after June 30, 2007) for permit coverage for tlrei1· sites 1nustfull)' co1np/y lvith the new SfV1.\-fP organizah·on, plan require111ents1 and b11ple111entation. I. Site Description: The requirement to provide an estimate of the nm-off coefficient lras been removed. The nm-off coefficient as currently utilized in tire SWMP may not contribute s1if/iciently to permit compliance tojustifY the effort in detennining accurate values. See Part J.C./ of the pem1it. However, tire Division still encourages use of the coefficient as needed to adequately evaluate site-specific BMP selection and design criteria (e.g., pond capacities, BMP location, etc.) See Section C.2 of the SWMP guidance (Appendix A of tire permit application). 2. Site Map: Tiie requirement to identifY boundaries of the I 00-year flood plain lras been removed. The boundaries as currently utilized in the SWMP may not contribute sufficiently to permit compliance to justifY the effort In determining their location. See Part J.C.2 of the permit. 3. Stormwater Management Controls: This section has been modified to require identification of a SWMP Administrator and all potential pollutants sources in the'SWMP. See Part l.C.3 of the pennit. a) The SWMP Administrator is a specific ind/vldual(s), position or title who is responsible for the process of tleveloping. implementing, maintaining, and revising the SWMP. This Individual serves as the comprehensive point of contact for all aspects of the facility's SWMP. Tills requirement may necessitate changes to ex/sling permittees' SWMPs. II. CHANGES IN THIS GENERAL PERMIT (cont.) PARTll Permit· Page 26 Pennit No. COR-030000 b) The req11lreme11t to identify Potelllial Po/11110111 So11rces has bee11 expa11ded to inc/11de more details/or the evaluat/011 of such sources. This evaluation allows/or the appropriate selectlon of BMPsfor impleme/llat/011 at a facility or site. Additio11al/y, this sect/011 was added to be consistent with the SJVlvJP guide. This requireJ11e11t 111ay necessitate cltauges to existing permittees' SWMPs. c) Best Ma11agement Practices (BMPs) for Stormwater Poll11tio11 Preventio11: This sect/011 was modified to req11ire the following items to be addressed in the SWMP. These requiremems 111ay necessitate changes to existi11g per111ittees 'SW1'1/Ps. Th ls section also requires that the SWMP provide installation and impleme11tatio11 specificatio11s for each BMP ide11tified in the SWMP. For structural BMPs, i11 most cases, this m11st include a tech11ical draw/Ilg to provide adequate i11stal/ation specifications. See Part l.C.3(c). i) Dedicated concrete or asphalt batch plants. This section requires that the practices 11sed to reduce the pollutants in stor11nvater discharges associated 1vith dedicated concrete or asphalt batch pla11ts be idelllified in the SWMP. (Coverage 11nder the co11struction site SWMP and permit is.!lQ!. required for batch pla/l/s if they have alternate CDPS permit coverage.) ii) Vehicle tracking control. This section req11ires that practices be Implemented to co11h·ol sediment from vehicle tracking, and that all such practices implemellfed at the site be clearly described in the SWMP. iii) Waste 111a11age111ent and disposal. This section requires tltat the practices i111ple111e11ted al the site to control sto11nwater polfutio11/ro1n co11stn1ction site lvaste, including concrete waslzolll activities, be clearly described in the SWMP. It also requires that concrete lvashout activities be conducted in a n1anner that does not contribute pollutants to su1face }Vaters or stor11nvater runoff. iv) Concrete Washout Water. Part I.D.3(c} oftlze pe1111it has been revised to condilionally authorize discharges to the ground of concrete lVash 1valer fron1 1vashing of tools and concrete mixer chutes wizen appropriate BMPs are implemented. The permit prohibits the discharge of concrete lVas/Jout water to sulface 1vaters and to stor111 sewer syste111s. Part l.C.3(c}(7) of the permit requires that BMPs be in place to preve/11 swface discharges of concrete washout \Valer from the site. The use of unlined pits to contain concrete 1vashout \Va/er is a co1n111011 practice in Colorado. The Division has further evaluated the need fora permit for discharge of concrete washout water to the ground. The Division has detennlned that the use of appropriate BMPs for on-site was!Jing of tools and concrete mixer chutes would prevent any significant discharge to groundwater. BMPs to protect groundwater are required by Pal'f l.C.3(c)(7) of the permit, Beca11se pH is a poll11tantof concemfor washout activities, the soil must have adequate buffering capacity to result in protection of the groundwater standard, or a li11er/contab11nent 1nust be used. The following 1nanage111ent practices are recommended to prevent an impact from unlined pits to groundwater: (I) the use oftlze washout site should be temporary (less than I year), and (2) tlze washout site should be not be located in an area where shallow groundwater may be present, such as near 11a1tu·a/ drainages, spr;ngs, or 1vetla11ds. PARTII Pennit -Page 27 Pennit No. COR-030000 II. CHANGES JN THIS GENERAL PERMIT (co11t.) Where adequate n1anagen1e111 practices are not followed to protect g1·oundlvater quality, tlte Depart111ent may require discharges to unlined pits to cease, or require the entity to obtai11 alternate regulato1y approval through 11oticefrom either tire Water Quality Co11trol Division or the Hazardous Materials and Waste Management Dlvisio11. In addition, Part I.D.l(b} of the permit has been revised to clearly state that the permit cloes not authorize on-site pennanent dlsposal of concrete 1vashout lVaste, only temporary containment of concrete lvashout lvater from lvashing of tools and concrete 1nixer ch11tes. Upon termination of use oft/re was/rout site, accumulated solid waste, including concrete waste and any conta1ninated soils, must be ren1ovedfron1 the site to prevent 011-site disposal of solid waste. v) Construction Dewatering. Part I.D.3(d) of the permit has been revised to conditionally authorize discharges to the ground oflvaterfi·o1n co11structio11 de•vatering activities when appropriate BMPs ai-e implemented. The permit does not authorize the discharge of groundwater from construction de\vatering to su1face \Yalers or to stor1n sewer systen1s. Pan I.C.3(c)(8) of the permit req11ires that BMPs be in place to prevent sulface discharges. The permittee may apply for coverage under a separate CDPS discharge permil, such as lhe Co11sb·11ctio11 Dewatering general permit, if there is a potential for discharges to s1uface 'rvaters. The Division has determined that potential pollutant so11rces introd11ced into groundwater frorn constn1ction delvatering operations do not have a reasonable potential to result in exceedance of groundwater standards when the discharge is to the gro1111d. The primary pollutant of concern in uncontaminated ground•vater ls seditnent. Although technology- based standards for sediment do exist in 5 CCR 1002-41, the discharge of sediment to the ground as part of construction de\vatering does not have the reasonable potential to result in transport of sediJnent to the ground~vater table so as to result in an exceedance of those standards. For a discharge of water contaminated with other pollutants I/rat are p1·esent in concentrations that may cause an exceedance of grmmdwater standards, separate CDPS discharge pern1it coverage is required. Conta1ninated groundwater may include that contaminated wilh pollutants from a landfill, mining activity, industrial pol/11tant plume, underground storage tank, or other source of h11man-induced groundwater pollution and exceeding the State groundwater standards in Reg11/ations 5 CCR 1002-41 and 42. J. Tern1s and Conditions. General Lhnitations and Design Standards This section reiterates the requirement thatfac//lties select, install, implement, and maintain appropriate BMPs, fol/owing good engineering, hydrologic and pollution control practices. In addition, requirements for protection of water quality standards (see Part 1.D.J. (a) of the permit) and requirements to adequately design BMPs to prevelll pollut/011 or degradation of State waters (see Part J.D.2 of the permit} have been revised and arefi1/ly discussed in Part 111.B of the rati011ale, below. Additional language was a/so added to Section III.B oft/re rationale further clarifYing the expectations for compliance with this pennit. 1. Management o(Sile Waste This section has been modified to clarifY that on-site waste must be properly managed to prevent potential po//utio11 of State waters, and that t/Jis permit does not authorize on-site waste disposal. Solid waste disposal is regulated by the Hazardous Materials and Waste Management Division. PARTll Pennit -Page 28 Permit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (com.) K.

SWMP Revjew/Clza11ges: This section now req11ires that wizen clza11ges are made to site co11ditio11s, the SWMP must be revised bnmediate(v, except for some BMP description changes which conditio11ally may occur within 72 /tours. This req11ireme111 is included to both ensure that the SWMP be kepi accurate and up-to-date, and to clarijj! that stormwater management al a site typically should be proactive instead of responsive, and be integrated into site n1anage1nent to ensure it is calibrated with those changes. The section ivas also clarified to state that only changes in site conditions that do rwt require new or modified BMPs do not need to be addressed in the SWMP. See Part 1.D.5(c) of the per1nit. 2. S~IP Certi[icatio11: The previous permit was unclear on a requirement that the copy ofSWJ\IIP that ren1ai11s at the facility had to be signed in accordance •vitlz per111it signatory require1nents. This requirement has been deleted. The signatory requirement of Part lF.1 only applies to the SJV,\,f P if ii is to be submitted to the Division or to EPA. See Part I.F.l oftlte permit. L. Tern1s and Conditions. Post~Stor111 Inspections The previo11s permit required post-storm inspections, but did not specifY the timing of inspections. This sectio1111olV requires that post~storn1 event inspections generally be conducted H'il/Ji11 24 hours of the event. An alternative ti111eline has been a/101ved, Q!J];Lfor sites 1vhere there are no construction activities occurring follo1ving a storn1 event. For this condition, post-stor1n event inspections shall instead be conducted prior to comme11ci11g construction activities, but 110 later titan 72 !tours following the storm event, and the delay noted in tlze inspection report. Any exceptioufron1 the 1nini11u11n inspection sched1J/e is te111porary, and does not elinzinate tlze require111e11t to pe1forn1routine1iiainie11a11ce due lo the effects of a stor111 event, including n1ai11taining vehicle tracki1ig controls and re111ovi11g sedi111ent ji·o111 ilnpervious areas. /11111any cases, 1nai11tenance needs lvil/ require a 111orefrequent inspection schedule than the n1i11iln1un inspections required in the pern1it, to ensure that Bi\fPs cominue to operate as needed to comply with the permit.

The Winter Conditions Inspection Exclusion section has been 1nodified to include docu111entatio11 requirements for this exclusion. See Part l.D.6(a) of the permit. The Inspection Scope has been 1nod(fted to include the requirement to inspect 1vaste storage areas during inspections conducted in accordance with the pen11il. See Pait l.D. 6(b) of lite permit. 2. Tite requirements for sites to qualifY for reduced inspection frequencies for completed sites ltave been slightly modified (see Part I.D.6(a)(2) of the permit,). The requireme11t 11ow is that only co11struclio11 activities that disturb the ground swface must be completed. Construction activities that can be conducted without disturbance of lite ground surface; for example, interior building constructio11, and some oil well activities, would 1101 prohibit a site from otherwise· qualifYingfor lite reduced inspection frequency. In addition, the requirement for the site to be prepared for final stabilization has been slightly modified lo allow for sites that have not yet bee11 seeded to qualijj!, as lo11g as the site has otherwise been prepared for final stabilizalio11, i11cludi11g completion of appropriate soil preparatio11, ame11dments and stabilization practice.

CHANGES IN THIS GENERAL PERMIT (cont.) 3. The Inspection Repon/Records section (Part I.D.6(b)(2)) was added to clar!/Y requireme/lfs for inspection reports generated during a11 inspection conducted in accordance with Part I.D.6 of the permit. Inspection reports must be signed by the inspector, or the individual ver!fYing the corrective action indicated In the inspection report, 011 behalf of the permittee. Inspection reports are not typically required to be submitted to the Divisio11, and therefore, are not required to be signed and certified for accuracy in accordance with Part I.F.I of the permit. However, any inspection reports that are subn1ltted to the Division mustfo/la'tv the signatory requiren1ents contained in that section. N. Tenns and Conditions. Mqintenance. Repair. and Renlace1nent a( Control Practlces These sections have been added to clarify 1·equirementsfor maintaining the BMPs identified in the SWMP and for addressing Ineffective or failed BMPs. BMP maintenance and site assessment to determine the overall adequacy of stornnvater quality 1na11agement at the site 1nust occur proactive/y, in order to ensure adequate control of pollutant soul'ces at the site. In most cases, if BMPs are already not operating effectively, OI' have failed, the Issue must be addressed immediately, to pl'event discharge of pollutants. See Pal'ts I.D. 7 and I.D.8 of the permit. 0. Total Maximum Daily Load (TMDLI A section on TMDLs has been added. This section gives a general outline of the additional requil'eme111s that may be imposed by the Division if the facility discharges to a waterbody for which a stom1water-related TMDL is in place. See Section Vlll.C of the rationale and Part l.D.l I of the pennit. P. Additional Definitions Part I.E of the pennit has been modified to remove the definition ofr1moff coefficient, as it is no longer a pel'mit requirement. The definition for state waters has also been deleted, but can befomtd in Regulation 61. Q. Changes in Discharge The section 011 the types of discharge or facility changes that necessitate Division notification has been c/al'ified. See Part II.A.I of the permit. R. Non-Compliance Notlficati011 The section on notification to the Division regarding instance~ ofnon-co1npliance has been amended to clar!fY which types of11oncomp/iance require notification. See Part Il.A.3 of the pemrit. S. Short Tern• Cenifications The previous permit allowed small short-tenn construction activities to be a11thorizedfor a predetermined period from 3 to 12 months, and then a11tomatically expire (an inactivation req11est did not need to be submitted). The Issuance of these certifications has led to significant co11fi1sion and Incidents of noncompliance resulting from pennittees unintentionally letting their certifications expire prior to final stabilization, as well as issues regarding billing. Therefore, the provisions for short-term certifications have been deleted. T. Bypass The Division has revised the Bypass conditions In Part II.A.5 of the permit to be consistent with the requirements of Regulation 61.8(3)(i). The revised language addresses under what rare occurl'ences BMPs may be bypassed at a site. Ill. BACKGROUND PARTll Permit· Page30 Permit No. COR-030000 As req11ired 11nder the Clean Water Act amendmeJl/s of 1987, lite E11viro11me11tal Protectio11 Agency (EPA) ltas established a framework for reg11latlng municipal a11d i11d11slrial stonmvater discharges. This framework is 1111der lite National Poll11ta11t Discharge Eli111i11alio11 System (NPDES) program (Note: The Colorado program is refen·ed to as tlte Colorado Discharge Permit System, or CDPS, i11stead ofNPDES.) Tlte Water Quality Control Divisio11 ("the Division'~ ltas storm water regulalio11s (5CCR 1002-61) i11 place. These reg11latio11s req11ire specific types of industrial facilities that discharge ston11water associated with industrial activity (i11dustrial stormwate11, to obtain a CDPS permit for such discharge. The reg11lations specifically inc/11de constructio11 activities that disturb one acre of land or Jnore as industrial facilities. Construction activities that are part of a larger conunon plan of developn1ent lvhich disturb one acre or inore over a period of thne are also included. A. General Per1nits The Division has determi11ed that tlte use of general permits is the appropriate procedure for /11111dling most of the thousa11ds of industrial storm water applications within the State. B. Pern1it Requiren1ents This per1nit does not itnpose nu111eric effluent /iJ11its or require subtnission of effluent 1no11itori11g data in the permit application or in the permit itself The pennlt instead imposes practice-based effluent limitalio11s for stor1n\vater discharges through the requirement to develop and i111p/en1ent a Stornnvater Managetnent Plan (SW1\1P). Tire narrative pennit require1nents include prohibi1lo11s against discharges of11011-stor11nvater (e.g., process wa1e1]. See Pa/'/ l.D.3 of the permit. The permit conditio11sfor the SWMP include the requiremeJl/for dischargers to select, implement and maintain Best Manage1nent Practices (BJ\1Ps) at a per111lt1ed cons1ruction site that adequately 1nini111ize pollutants in the discharges to assure conzpliance with the ter1ns and conditions oft/ze per111it. Part J.D.2 of the per111it includes baSic desigii standards for BMPs i11iple111ented at the site. Facilities tnust select, install, i111ple1nent, and tnaintain appropriate BiVIPs, fo/lowing good englneerlng, hydro/ogle and pollution control practices. BMPs implemented at the site must be adequately designed to co11troi all potential po/luta/I/ sources associated with construction activity to prevent pollution or degradation of Stale waters. Pollutio11 is defined in CDPS regulations (5CCR 1002-61) as man-made or ma11-i11duced, or natural alteration of the physical, chemical, biological, a11d radiological integrity of water. Utilizing industry-accepted standards for BMP selection that are appropriate for the conditions and pollutant sources present will typically be adequate to meet these criteria, since construction BMPs are illlended to prevent the discharge of all but minimal amoullls of sediment or other pol/uta/l/s that would not result i11 actual pollution of State waters, as defined above. However, site-specific design, including ongoing assessment of BMPs and pollutant sources, Is necessary to ensure that BMPs operate as intended. The pennitfurther requires that storn1water discharges fro111 construction activities shall not cause, have the reasonable potential to ca.use, or 1neasurably contribute lo an excursion above any ivater quality standard, including 11an·ative standards for water quality. This condition is the basis for all CDPS Discharge pe1111/ts, and addresses the need to ensure //rat waters oft/re State mailllain adequate water quality, 111 accordance lvilh water quality standards, to continue to n1eet their designated uses. It Is believed that, in 1110s/ cases, BMPs can be adequate to meet applicable water quality standards. If water quality impacts are noted, or the Division otherwise deter1nines that additional permit require1ne11ts are necessary, they are typically imposed as follows: 1) at the renewal of this general permit or through a general pennit specific to an industrial sector (if /he issue is sector-based); 2) through direction from the Division based 011 the impleme11tatio11 ofa TMDL (if the issue is watershed-based); or 3) if the issue is site-specific, through a revision to the certificatio11frou1 the Division based 011 an inspectio11 or SWMP review, 01· through an individual per111it.

See Section VII of the rationale. C. Violat1011s!Penalties Dischargers of stormwater associated with Industrial activity, as defined in the CDPS regulations (5CCR 1002-61), that do not obtain coverage under this or other Colorado general permits, or under an individual CDPS permit regulating industrial stormwater, will be in vio/alio11 of the Federal Clean Water Act and the Colorado Water Quality Control Act, 25-8-101. Forfacilities covered under a CDPS permit, failure to coniply lvit/J any CDPS permit requiren1ent constitutes a violation. As of the tin1e of pern1it issuance, civil penalties for violations of the Act or CDPS permit requirements may be up to $10,000 per day, and criminal pol/II/ion of state waters is punishable by fines of up to $25, 000 per day. JV. STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY The stormwater regulations (CDPS regulations (5CCR I002-61)), require that stormwater discharges associated with certain industrial activities be covered under the pennit program. Constn1ctlon activity that disturbs one acre or inore during the life of the project is specifically incillded in the listed industrial activities. This permit is Intended to cover most stormwater discharges from construction facilities required by State regulation to obtain a perniit, A. Construction Actlvio• Consh·uction activity includes ground surface disturbing activities including, but not li1nited to, clearing, grading, e.tcavation, denzolition, installation ofnmv or in1proved haul and access roads, staging areas, stockpiling of fill materials, and dedicated borrow/fl/I areas. Construction does not include routine maintenance lo maintain original line and grade, hydraullc capacity, or original p11rpose of the facility. (The n1aintena11ce exclusion is intended for projects such as road resuifacing, and lVhere there will be less than one acre of additional ground disturbed. Improvements or upgrades to existingfaci/ities or roads, where at least one acre is disturbed, would not qualify as "routine maintenance.") Definitions of additional tenns can be found in Part I.E of the permit. Stonn1vater discharges Jron1 all co11st111ction activity require permit coverage, except for operations that result in the disturbance of Jess than one acre of total land area and which are not part of a larger common plan of development or sale. A "larger common plan of development or sale" is a contiguous area where multiple separate and distinct construction activities may be taking place at different times 011 different schedules. B. Tvees o(Discharges/Actlvities Covered I. Stormwater: This permit is intended to cover most new or existing discharges composed entirely of stonnwater from construction activities that are required by State regr1/ation to obtain a permit. This incllldes stormwater discharges associated with areas that are dedicated to producing earthen materials, such as soils, sand, and gravel, for use at a single construction site. These areas may be located at the construction site or at some other location. This permit does not authorize the discharge of mine 1vater or process water fronz borrolV areas. This permit 1nay also cover stormlvater discharges associated with dedicated asphalt plants and concrete plants located at a specific constn1ctio11 site.

MasterSWMP PART II Permit· Page 35 Permit No. COR-030000 Often, a large construction project will involve nzultiple snzaller construction sites that are 1vithi11 a conunon plan of development, or m11ltiple well pads 11nder constmction within an oil and gas well field. Pollutant so11rces and the types of BMPs 11sed can be relatively consistellt In s11ch cases. A permittee co11/d significantly streamline the SWMP development process through the use of a master SWMP. SWMP i1ifonnation must be developed and maintained for all construction activities that exceed one acre (or are part of a common plan of development exceeding one acre) conducted withi11 the permitted area. By developing a single n1aster plan, the pe11nittee can e/inrinate the need to develop repetitive ilifor111ation in separate plans. Such a plan could include hvo sections, one containing a reference section with inforn1ation· applicable to all sites (e.g., installatlo11 details and mal11tena11ce requiremellls for many standard BMPs, such as silt fence and erosion blankets), and the second containing all of the iJiformation specific to each site (e.g., site BMP map, drai11age plans, details for BMPs requiring site specific design, such as retention ponds). As new activities begin, iJiformation required in the SWMP is added to the plan, and as areas become finally stabilized, the related information is removed. Records ofinfom1ation related to areas that have been finally stabilized that are re1novedfro1n the active plan 1nust be n1aintainedfor a period of at least three yearsfi·o1n the date that the associated site is finally stabilized. C. Tota/ Maximum Dailv Load fTMDL/ If the designated use of a stream or water body has been impail'ed by the presence of a po//utant(s), developmellt of a Total Maximum Daily Load (TMDL) may be required. A TMDL Is an estimate of allowable loading in the waterbody for the po//utant In question. Types of discharges that are or have the poteniial to be a significant source of the pollutant are also identified. If a TMDL has been approved for any lvaterbody into 1vhich the pernrittee discharges, and stornnvater discharges associated 1vlth constn1ction activity have been assigned a pollutant-specific Waste/oad Allocation (WLA) under the TMDL, the Division will either: I. Notify tfle pennittee of tile TMDL, and amend the permittee's certification to add specific B,VJPs andlol' other require111e11ts, as appropriate; or 2. Ensure.that the r,~mL is being implemented properly through alternative local requirements, such as by a munlclpal stormwater permit. (The only current example of this is the Cheny Creek Reservoir Control Regulation (72.0), which mandates that municipalities within tile basin require specific Blv!Ps for construction sites.) See Part 1.D. I I of the permit for further ilifonnation. D. Monitoring Sampling and testing ofstonnwater for specific parameters is not required on a routine basis under this pern1it. Ho1veve1; the Division reserves the right to require sa1npling and testing on a case-by-case basis, in the event that the1·e is reason to suspect that compliance with the SWMP Is a problem, or to measure the effectiveness of the BMPs in removing pollutants in the e.ff/uent. See Part I.D.J(e) of the permit. E. Facilltv Inspections Constnfction sites typically must inspect their stonnwater manage1nent controls at least every 14 days and 1vithin 24 hours afler the end of any precipitation or snowmelt event that causes suiface erosion. At sites or portions of sites where ground-disturbing constmctlon has been completed but a vegetative cover has not been established, these inspections must occur at least once per mo1Jth. (At sites where persistent snow cover co11ditions exist, inspect/011s are not required during the period that nielting conditions do not exist. These ' VIII. TERMS AND CONDITIONS OF PERMIT (cont.) PART II Permit· Page 36 Pennit No. COR-030000 (:Ollditions are only expected lo occur al high elevatio11s withi11 the Colorado mountains.) For all of lhese i11spec1/011s, records mus/ be kept on file. Excep1io11s lo the inspection requirements are de/ailed ill Part J.D.6 oflhe permit. F. SWMP Revisions The pern1ittee shall an1end the SW.i\1.P lVhenever there is a change in design, co11structio11, operation. or mai11te11a11ce of the site, which would require the imple111e11/ation of new or revised BMPs. The SWMP shall also be amended if it proves to be i11effeclive ill achieving the ge11eral objectives of co11trol/i11g pollutants in slor11nvater discharges associated with constructio11 aclivity. The tilningfor co1npietlon of SWlv!P changes is detailed in Parts 1.D.5(c) and l.D.5(d) of the permit. SWMP revisions shall be made prior lo change in the field, 01· in accordance with Part l.D.5(d) of the pern1it. G. Reporting The i11spectio11 record shall be made available to the Division upon request. Regular submittal of an a111111a/ report is no/ required i11 this permit. See Part l.D.9 of the pen11it. H. A111111al Fee The pennittee is required to submit payme/11 of an a11mialfee as set forlh i11 the Water Quality Co11trol Act. Permillees will be billed for the i11itial permit fee withi11 a few weeks of permit issuance and then annually, based on a July I through June 30 billing cycle. I.

Signature: ________________ _ Date __ _ Site-Specific Storm-Water Management Plan Paae 1/3 Site Name: Fresh-Water Pond I Date of Plan: October 28 2007 1. Site I Activitv Descrlntion Site Description I Location: A 2.6-million gallon (350,000 cubic foot) Fresh-Water Pond will be constructed on near the confluence of Tom Creek and Clear Creek. The fresh water is required for well completions associated with the development of natural gas wells. Site access information is provided in the master plan. The Fresh Water Pond is located about 2.3 miles northwest of the property access point (end of CR 211). See Figure 1, Site Location Map (Master Plan). Site Area/Disturbed Area: The Fresh-Water Pond site Is located on about 5.6 acres of a 4,311.69 acre parcel, north of the confluence of Tom Creek and Clear Creek (west side of main access road). Construction activities potentially will disturb all of the 5.6 acres. Site Solis I Slopes: About one foot of organic topsoil covers the site. Underlying soils consist primarily of clay (CL) or gravely clay (GC) with minor lenses of poorly sorted and I or silty sand (SP/SM). Properly compacted clays resist erosion but once erosion channels are established clayey soils are easily transported. Original site slopes vary from 100: 1 to 30: 1 in IJ?<i! vicinity of the pond with slopes ranging from 7: 1 to 4(1.· b'~twl;!Bn the northeastern pond berm and the area acces~[~a(it;:,;"'· Receiving Waters: Storm-water runoff from "\jc..

These projects include existing and proposed well pads, a central production facility site, fresh water and produced water ponds, and pipeline alignments. The project area referred to in this report is approximately 400 acres in size (Figure I). 2.0 LANDSCAPE SETTING 2.1 Terrain and Vegetation Communities The terrain ranges from very steep mountain side-slopes to gently sloping valley bottoms (Appendix C. Photos 2 and 3). Elevations in the project area range from 6,850 feet in the Tom Creek drainage to 5,950 feet in the Clear Creek bottom land. The predominant vegetation community in the northern Tom Creek drainage bottom is mountain boxelder (Acer negundo ), scattered Douglas-fir (Pseudotsuga menziesii), redosier dogwood (Cornus sericea), mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana), and oakbrush (Quercus gambelii). The mountain side-slope vegetation includes mountain big sage, Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis), Utah serviceberry (Amelanchier utahensis), oakbrush, and Indian ricegrass (Achnatherum hymenoides). The mountain side-slopes also contain barren areas of steep shale talus, which supports small populations of sun-loving meadowrue (Thalictrum heliophilum). Vegetation in the Potts Creek drainage and the Tom Creek drainage south of the Potts Creek confluence are similar. Mountain boxelder and narrow leaf cottonwood (Populus angustifolia) are common trees. Shrubs are dominated by basin big sagebrush (Artemisia tridentata Nutt. ssp. tridentata) and Wyoming big sagebrush, although some mountain big sagebrush is also found. Vegetation on the steep side-slopes is mountain big sagebrush, oakbrush, Utah serviceberry, and often thick Indian ricegrass. The mountain side-slopes also contain barren areas of steep shale talus, which support small populations of sun-loving meadowrue and Roan Cliffs blazingstar (Mentzelia rhizomata). Along Clear Creek the dominant trees are boxelder, New Mexico locust (Robinia neomexicana) and narrow leaf cottonwood. Basin big sagebrush is the predominant shrub along with various (often weedy) forbs and grasses. The vegetation on the east-facing side-slope of Clear Creek drainage consists of very thick Utah service berry, scattered oakbrush, and abundant creeping barberry (Mahonia repens). Vegetation on the drier west-facing slope includes Utah juniper (Juniperus osteosperma), shadscale saltbush (Atriplex confertifolia), Osterhout's penstemon (Penstemon osterhoutil), rubber rabbitbrush (Ericameria nauseosa), basin big sagebrush and Indian ricegrass. 2.2 Soil Types The Chevron Clear Creek I Tom Creek Weed Survey project area includes just three main types of soil. The northerly portion of the project area includes part of the Tom Creek drainage and the West Water Engineering Page I of 14 4/21/2008 • WeedPatoties Infeste d Areas c:J TARA CJ VETH, CYOF i=J VETH.

This portion of the survey area lies entirely on Grobutte very channery loam, 30-60% slopes. The Grobutte soil formed on mountain sides and hills from mixed colluvium parent material. Characteristic native vegetation is Wyoming big sagebrush, bluebunch wheatgrass (Pseudoroegneria spicata), needle and thread grass (Hesperostipa comata), and Indian ricegrass. South of Section 25, the Tom Creek drainage broadens and the terrain becomes less steep along the creek. The soil here consists ofHapple very channery sandy loam, 12-25% slopes. The Happ le soil formed on toeslopes and alluvial fans from Green River formation alluvium or colluvium. Characteristic native vegetation on the Happ le soil is Wyoming big sagebrush, bluebunch wheatgrass, needle and thread grass, and Indian ricegrass. The steeper areas on either side of Tom Creek are on Grobutte soil as described above. The southern portion of the project area includes short stretches of Clear Creek drainage both above and below the confluence with Tom Creek. The very steep areas lie on Grobutte soil. Gentler slopes near Clear Creek consist of the Happ le soil. The almost level flood plain of Clear Creek lies on Cumulic Haploboroll, 1-3% slopes. The Cumulic Haploboroll formed from Wasatch shale or Green River shale alluvium and has a thickened surface horizon from material added during seasonal flooding. Vegetation observed on the Cumulic Haploboroll soil is primarily mountain boxelder and introduced and naturalized New Mexico locust. The New Mexico locust has crowded out most native shrubs one would expect such as skunkbush sumac (Rhus trilobata) and willows (Salix spp.), see Appendix C, Photo 4. 3.0 NOXIOUS WEEDS Noxious weeds are plants!that are not native to an area. Most have come from Europe or Asia, either accidentally or as ornamentals that have escaped. Once established in a new environment they tend to spread quickly since insects, diseases and animals that normally control them are absent. Noxious weeds are spread by man, animals, water, and wind. Prime locations for the establishment of noxious weeds include roadsides, sites cleared for construction, areas that are overused by animals or humans, wetlands, and riparian corridors. Subsequent to soil disturbances, vegetation communities can be susceptible to infestations of invasive or exotic weed species. Vegetation removal and soil disturbance during construction can create optimal conditions for the establishment of invasive, non-native species. Construction equipment traveling from weed-infested areas into weed-free areas could disperse noxious or invasive weed seeds and propagates, resulting in the establishment of these weeds in previously weed-free areas (Photo 1). The Colorado Noxious Weed Act (State of Colorado 2005) requires local governing bodies to develop noxious weed management plans. Both the State of Colorado and Garfield County (Garfield County Vegetation Management and Garfield County Weed Advisory Board 2002)maintain a list of plants that are considered to be noxious weeds. The State of Colorado noxious weed list includes three categories. List A species must be eradicated whenever detected (none were found). List B species include weeds whose spread should be halted ( 4 species found). List C species are widespread, but the State will assist local jurisdictions which choose to manage those weeds (2 species found). West Water Engineering Page 3of14 4/21/2008 ) Photo 1. Potential weed vector -accumulated soil on equipment The Garfield County Weed Advisory Board has compiled a list of 21 plants from the State list considered to be noxious weeds within the county (see Appendix A). Three of those weed species were found in, or near, the project area. The Garfield County Weed Advisory Board has duties to: 1) develop a noxious weed list; 2) develop a weed management plan for designated noxiou s weeds; and 3) recommend to the Board of County Commissioners (BOCC) that identified landowners submit an integrated weed management plan for their properties. 3.1 Survey Methods Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the plant site and surrounding property (NRCS 2008). A field inspection of the project area was conducted by West Water Engineering (WWE) biologists on April 1, 3, 11, and 15 , 2008. WWE biologists surveyed the area to identify vegetation communities and to search for, identify, and map noxious weed species. Vegetation types were determined through field identification of plants, aerial photography, and on-the-ground assessments of plant abundance visible during the survey. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998, Weber 2001). Photographs were taken of the general project location, vegetation, terrain, and other specific biological findings and can be found in Appendix C. Locations of weeds and other features included in this report were recorded with the aid of a handheld global positioning system instrument (GPS) using NAD83 /WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 12S. Westwater Engineering Page 4of14 4/21/2008 3.2 Observations The most prevalent listed weeds were common mullein, musk thistle, houndstongue, and downy brome. A problematic (but not listed) weed found in the project area was purple mustard (Chorispora tenella). It was found primarily in disturbed areas and abandoned fields. See Table 1 for the general location of listed weeds. Specific UTM coordinates of weeds can be found in AppendixB. Table 1.

Superscript -Colorado State B or C list. 3.3 Treatment and Control of Noxious Weed Infestations Invasive and noxious weeds commonly occur along ditches, creek corridors and adjacent drainages, especially along riparian areas, pipeline routes, disturbed areas such as well pads, and roadsides, and abandoned fields. Areas near Clear Creek and Tom Creek were frequently noted to have infestations of common mullein and houndstongue. Three weed species from the Garfield County list were found in the project area and are indicated by bold type in Table 2. Included in Table 2 are weed life cycle type, state listing category, and recommended control methods for each weed species. Those in regular type were also observed during the survey and are listed by the State of Colorado as noted (CWMA 2007). The locations of these weeds were plotted on the project map (Figure 1). Except for a dense infestation on the east side of Clear Creek, south of the confluence of Tom Creek, downy brome was not plotted as it is very widespread throughout the area.

"'"'Type: A-annual, B-Biennial, P-Perennial 3.4 Recommended Treatment Strategies It is important to know whether the target is annual, biennial, or perennial to select strategies that effectively control and eliminate the target. Treatment strategies are different depending on plant type, which are summarized in Tables 3 and 4. Herbicides should not always be the first treatment of choice when other methods can be effectively employed. Table 3. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production I. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. develop, cut and bag seed heads. 2. Cut roots with a spade just below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. If seeds 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. (Srrota 2004) West Water Engineering Page 6of14 4/21/2008 ·' Table 4. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 1. Allow plants to expend as much energy from root system as possible, do not treat when fir st emerging in spring , but allow growth to bud/bloom stage. If see ds deve lop, cut and bag if possible. 2. Herbicide treatment at bud to bloom stage or in the fall (recommended, after August 15 when natural precipitation is present). In the fall, plants draw nutrient s into the root s for winter storage . Herb icides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time, another seaso n of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on the roots at this time. 3. Mowing usua ll y is not recommended becaus e the plants will flower anyway; seed production shou ld be reduce d. Many studies have shown that mowing perennials and sp raying the re-growth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefo re, it is imperative to know the species and its basic biology. Timing of applicat io n mus t be done when biologically appropriate, which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only Yi" -l " long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants . Hand pulling can be effective on sma ll patches but is very labor intensive because it must be done repeatedly. (Sirota 2004) Herbicide treatment with two or more herbicide modes of action in fall (after approximately August 15 when natural precipitation is present) is the best method to control difficult species . Some weeds, particularly annuals and biennials, can deve lop resistance to herbicides. The ability to quickly develop immunity to herbicides, especially they are used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration . Most misuse seems centered around excessive use either in frequency or concentration. This result s in mostly top kill and an immune phenotype. 3.5 Life Cycle and Management Calenda r s Best results in the control of tamarisk, ho undstongue, bull and milk thistles can be achieved by fo ll owing the recommended timetable presented in Table 5.

It is also appropriate to contro l common mullein. One co lumn that should be added is cutting of rosettes, which can be done any time during growing. Figure 2. Life Cycle and Management strategies for biennial thistles (Hartzler 2006) Herbicide Appllcatl on Vear1 3.6 Commercial Applicator Recommendations Htrt>. Appl . Mowtng Vear2 A certified commercial applicator is a good choice for herbicide control efforts. Regulations may require a Colorado licensed applicator. An applicator has the full range of knowled ge, skills, equipment and experience desired when dealing with tough noxious weeds. Reclamation farming services using multiple seed bin range drills and specialized related equipment is availab le and should be used for reclamation seeding projects. Common chemical and trade names may be used in this report. The use of trade names is for clarity by the reader. Inclusion of a trade name does not imply endorsement of that particular brand of herbicide and exclusion does not imply non-approval. Certified commercial applicators will decide which herbicide to use and at what concentration according to label directions. Landowners using unrestricted products must obey all label warnings, cautions, and application concentrations. The author of this report is not responsible for inappropriate herbicide use by readers. 3.7 Best Management Practices -Noxious Weeds The fo ll owing practices should be adopted for any construction project to reduce the costs of noxious weed control. The practices include : Westwater E ngineering Page 8of 14 4/21/2008 • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling; • wetland vegetation, if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub-soil relative to the position from which the wetland sod was removed; • cut-off collars should be placed on all wetland and stream crossings to prevent back washing or draining of important aquatic resources; • in all cases, temporary disturbance should be kept to an absolute minimum; • equipment and materials handling should be done on established sites such as the northern point of origin to reduce area and extent of soil compaction; • disturbances should be immediately re-seeded with the recommended mix in the re- vegetation section; • topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses, if stored longer than one growing season; • prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • if working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially seed-bearing soils and vegetative debris prior to moving to uncontaminated terrain. In areas with slope greater than 3%, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When utilizing hydro-seeding followed by mulching, imprinting should be done prior to seeding unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. Herbicides: Difficult species respond better to an application of a combination of two or more chemical modes of action (biological reason for plant death) rather than one (Boerboom 1999). It has also been found that use of two different groups of chemicals in the same mode of action can increase effectiveness on difficult species, e.g., phenoxys and benzoic acids or carboxylic acids and benzoic acids in a mix. Some come commercially pre-mixed, e.g., Crossbow and Super Weed-be-Gone Max, which are available over the counter. However, some of the most effective herbicides are restricted use and available only for licensed applicators. Professionals or landowners using herbicides must use the concentration specified on the label of the container in hand. Herbicides generally do not work better at higher concentrations. Most herbicide failures observed by WWE are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient translocation process. Most herbicide applications should use a surfactant if directed on the herbicide label or other adjuvants as called for on the herbicide label. WestWater Engineering Page 9of14 4/21/2008 Grazing: Grazing should be deferred, in reclaimed areas, until the desired grass species are established. Mechanical: Bull thistle was found in low density and is an example where control could be accomplished mechanically. Effectiveness can be increased by severing the root just below the crown of noxious weeds instead of at greater depths. Alternative Methods: An alternative method, particularly for downy brome infestations and poor or destroyed topsoil, is the application of vesicular-arbuscular mycorrhizal fungi typically referred to as AMF. These fungi, mostly of the genus Glomus are symbiotic with about 80% of all vegetation. Endo-mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful when reclaiming this project. In symbiosis, the fungi increase water and nutrient transfer capacity of the host root system by as much as several orders of magnitude (Barrow and Mccaslin 1995). Over-the-counter commercial products, which are better adapted to coating seeds when re- seeding and treating roots of live seedling trees and shrubs at time of planting, come in powder form and are available from many different sources. Some also come in granular form to be spread with seed from a broadcast spreader. The best AMF products should contain more than one species. All Colorado State Forest Salida District tree and shrub plantings include the application of AMF. According to District Forester Crystal Tischler, "AMF is worth it" (Tischler 2006). Most, if not all, Colorado Department of Transportation re-vegetation/re-seeding projects now require use of AMF and BioSol, a certified by-product of the penicillin manufacturing process composed primarily of mycelium. Compacted soils respond well to fossilized humic substances and by- products called humates. These humates, including humic and fulvic acids and humin were formed from pre-historic plant and animal deposits and work especially well on compacted soils when applied as directed. Biological control of widespread infestations, in the project area, using natural insect agents are available for tamarisk (see Table 2) and musk thistle. This later weed may be controlled by the musk and plumeless thistle rosette weevil, Trichosirocalus horridus, and the thistle defoliating beetle, Cassida rubiginosa, which feeds on the foliage of Canada, musk, and plumeless thistles (Sullivan 2004 ). 4.0 REVEGETATION -RECLAMATION 4.1 Project Area The project area includes a variety of terrain including steep mountain side-slopes, rolling hillsides, and gently sloping bottomland. Successful reclamation of the project area is dependent upon soil type and texture, aspect, slope, proper weed control and re-vegetation with suitable plant species. Based on the soil types, terrain, and the presence of noxious weeds in the project area, successful reclamation is most likely if a seed mix of grasses is used (Tables 6 and 7). This will allow control of noxious weeds while establishing vegetation in the disturbed areas. Two seed mixes West Wat er Engineering Page 10of14 4/21/2008 Table 6.

"' are presented based on soil type and available moisture; one for the gentler, often drier, lower slopes and one for the higher altitude steeper sites. Note: Re-vegetation on very steep or west facing mountain side-slopes may be difficult due to thin soil and harsh climatic conditions. Surface disturbance should be minimized in those areas. For best results and success, the recommended grass mixture reseeding should be done in late autumn. The reseeding rate should be doubled for broadcast application (CNHP 1998). Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars, where applicable. Alternative seeding methods include, but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re- harrow, preferably at a 90 degree angle to the first harrow; • hydro-seeding (most economical in terms of seed cost); and • hand raking and broadcast followed by re-raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. After desired grasses are established and control of target weed species is successful, then shrubs, forbs and trees can be planted without concern for herbicide damage. Few native forb seeds are available commercially as cultivars. Most are collected from natural populations. Native shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past experience has shown that stabilizing the soil with grasses, accomplishing weed control, and then coming back to plant live, containerized woody species in copses has been the most cost effective method for establishing the woody species component of the plant community. For sites where soil disturbance will be temporary, grasses should be drilled after construction activities cease and the equipment removed from the site. After two years of controlling weeds (with herbicides) and allowing the grasses to become established, forbs and woody species should be inter-seeded or hand-planted to increase the diversity and value of the reclamation plantings. 5.0 REFERENCES Barrow, J.

Personnel will not attempt to continue working on or remain at a location if the facility is in an unsafe condition. All personnel are authorized to stop work if an unsafe condition posing an immediate hazard occurs. No reprimands will be given if the situation later proves less serious than thought. Hazards of a less serious nature should be brought to the attention of the supervisor who will assess the situation and initiate appropriate action. Under emergency response conditions, or drills, employees are expected to act only in accordance with their training. At no time will any employee place themselves, or allow themselves to be placed, into a life-threatening situation. The following priorities will govern our response to any emergency situation: 1. The safety of employees takes precedence over all other considerations. 2. We will minimize impact on the environment once the safety of all personnel has been secured. 3. We will endeavor to minimize damage to or loss of property and equipment, keeping safety and environmental concerns at the top of our priority list. Emergency Action Plan: Scope: This written plan covers the designated actions employees (Chevron & Contractors) associated with the Skinner Ridge Delineation Project (Pieance Creek/Debeque, Colorado) must take to ensure their safety from fire, bomb threats, gas leaks, severe weather, or other emergencies.

The Base Fee is an estimate of the average number of hours of staff time devoted to an application, multiplied by an hourly rate for the personnel involved. The Board recognized that the subdivision and land use application processing time will vary and that an applicant should pay for the total cost of the review which may require additional billing. Hourly rates based on the hourly salary, and fringe benefits costs of the respective positions combined with an hourly overhead cost for the office will be used to establish the actual cost of County staff time devoted to the review of a particular project. Actual staff time spent will be charged against the Base Fee. After the Base Fee has been expended, the applicant will be billed based on actual staff hours accrued. Any billing shall be paid in full prior to final consideration of any land use permit, zoning amendment or subdivision plan. If an applicant has previously failed to pay application fees as required, no new or additional applications will be accepted for processing until the outstanding fees are paid. Checks, including the appropriate Base Fee set forth below, must be submitted with each land use application, and made payable to the Garfield Countv Treasurer. Applications will not be accepted without the required application fee. Base Fees are non-refundable in full, unless a written request for withdraw from the applicant is submitted prior the initial review of the application materials. Applications must include an Agreement for Payment Form ("Agreement") set forth below. The Agreement establishes the applicant as being responsible for payment of all costs associated with processing the application. The Agreement must be signed by the party responsible for payment and submitted with the application in order for it to be accepted. The complete fee schedule for subdivision and land use applications is attached.
