DESCRIPTION OF THE PROPOSAL The Building and Planning Department received a Special Use Permit (SUP) application for "Storage, Processing, and Material Handling of Natural Resource" in order to construct a lined water storage pond on a 27,000 -acre property owned by Encana Oil & Gas USA, Inc located at the end of County Road 215 north of Parachute and is also formerly known as the old UNOCAL property where extensive oil shale exploration and processing occurred. The location of the proposed pond is just beyond the private gate at the end of County Road 215 on a 3 -acre portion of the property. More specifically, the proposed storage pond will serve as a temporary holding pond where produced water generated from natural gas drilling operations in the area can be stored and then reused in drilling operations in the area operated by Encana Oil and Gas, USA. "Produced Water" is also classified as Exploration and Production (E&P) Waste by the Colorado Oil and Gas Conservation Commission (COGCC). The proposal specifically includes tanker trucks which will haul produced water from drilling sites to the subject site where the water is unloaded into enclosed large capacity off-load treatment tanks. These treatment tanks will serve as the primary separation point for lighter than water hydrocarbons and heavier than water solids/ paraffin/ wastes /oils ("petroleum constituents"). These tanks are also called separators where natural separation process allows the solids to be skimmed off the produced water then be hauled away for disposal while the produced water is pumped (from a pump located in an enclosed pump house) directly into the storage pond for reuse in drilling operations. The proposed pond will be able to contain approximately 215,000 barrels of produced water at capacity. The Applicant asserts that this pond will reduce the need for water hauling trucks to travel CR 215 to Parachute. The pond will operate 24 hours a day, year- round. An evaporation pit that contains, treats, and evaporates this water is dealt with in Section 908 Centralized E&P Waste Management Facilities of the COGCC rules. These rules also require that operators may be subject to local requirements for zoning which meant a Special Use Permit was required for the facility. II. BACKGROUND As you will recall, Staff brought the application to your attention on April 11, 2005 so that you could determine if a referral to the Planning Commission was necessary. You did not refer the application due to the limited nature of potential impacts to surrounding properties, the remote location of the property such that it is situated at the end of a dead-end county road which is used primarily for industrial traffic serving the existing industrial uses in the area with very limited general population traffic, the fact that the site itself will be situated in an industrial area already characterized by intense industrial activity from the oil shale exploration / processing activities, and the fact that the majority of water tanker trips generated to and from the site will occur on roads located on the privately owned 27,000 -acre property. As a result, you directed Staff to schedule the matter to be heard directly by the Board. Encana Water Storage Pond BOCC — 05116/05 Page 3 III. SITE DESCRIPTION The proposed site where the pond is to be located is physically situated on flat river basin land that is situated at the general confluence of West, East, and Middle Forks of Parachute Creek. The pond will be located on approximately 3 acres of the total 27,000 acre parcel owned by Encana. While the area where the pond is to be located, it is surrounded by steep slopes and canyons containing the three creeks. Much of the area near the pond has been denuded by the former oil shale operations and continues to be a location which contains staging areas for heavy machinery, large water hauling truck, drilling rigs, pipes, and a compressor station currently under construction. Dense mature riparian vegetation exists along the creeks as they pass through the area. As a result of a site visit conducted on Tuesday, May 10th, 2005, Staff discovered that the storage pond, in fact, has already been constructed, although the associated treatment tanks and pump have not been installed. The Applicant supplied all the technical construction / earthwork documentation that went out to bid to have the work done which has a date of January 19, 2005. To be clear, the grading permit requirements went into affect on October 1, 2004. By the fact that the pond has been constructed without a special use permit or a grading permit, it represents two violations of the County's building and land use regulations. This review attempts to address the remaining outstanding issues related to the constructed pond. Staff will also provide a presentation showing what has occurred on the site to date. Also, regarding review timelines, the application was initially submitted on February 10th, 2005. Staff completed a technical review and issued a letter of non-technical compliance by February 17th, 2005 (5 working days later). The Applicant provided additional information on March 10th, 2005. The matter was placed on the BOCC agenda for referral on April 11th, 2005 and scheduled for public hearing for May 16th, 2005. As a practical matter, this application has been fast -tracked for the benefit of the Applicant. IV. ZONING & ADJACENT USES The subject property is zoned Resource Lands (Gentle Slopes and Lower Valley Floor). The type of use requested falls under the definition of "Process, Storage and Material Handling of Natural Resources" which are contemplated as special uses in the Resource Lands (Gentle Slopes and Lower Valley Floor) zone district. The property also now known as the North Parachute Ranch was the area where a majority of the oil shale exploration and development occurred. The proposed pond is located on approximately 3 acres of a 27,000 acre property which is surrounded by properties also owned and utilized by the energy industry such as Chevron, Exxon/Mobile, Williams Production RMT, American Soda, etc. The neighboring uses on those lands appear to be rangeland grazing, farming, and resource extraction Encana Water Storage Pond BOCC — 05/16/05 Page 4 (natural gas drilling). V. AUTHORITY & APPLICABILITY Pursuant to Section 9.03.04 of the Zoning Resolution, an application for a Special Use Permit shall be approved or denied by the Board of County Commissioners after holding a public hearing thereon in conformance with all provisions of the Zoning Resolution. VI. REVIEW AGENCY AND OTHER COMMENTS Comments have been received from the following agencies / community groups and are integrated throughout this memorandum as applicable. 1. Town of Parachute: No Comments Received 2. Garfield County Road and Bridge Department: No Comments Received 3. Garfield County Vegetation Management: Exhibit F 4. Garfield County Oil and Gas Auditor: No Comments Received 5. Colorado Division of Wildlife: No Comments Received 6. Grand Valley Fire Protection District: No Comments Received VII. 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 thereunder 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 The proposed use does not appear to need or require potable water or wastewater services. As a matter of clarification, water produced from wells is defined as "produced water" whose disposal is regulated by COGCC Rule 907 which ultimately says... and operator may dispose of water... in one of the following ways...reuse the water for enhanced recovery, recycling, and drilling. In this regard, it also appears that the COGCC rescinds the authority of the Colorado Division of Water Resources (CDWR) if the produced water is not used for a "beneficial use" and is non -tributary. No sanitation service is required for the operation of the storage pond. Encana Water Storage Pond BOCC — 05/16/05 Page 5 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 The proposed pond is expected to generate an average of 10 water tanker trips and 2 pick-up trips per day into and out of the facility. Most of this truck travel will be coming from and going back to drilling sites on the North Parachute Ranch property on private roads constructed by the industry. The Applicant states that the pond will reduce the need for more trucks hauling water on CR 215 since the pond will be at the property where the drilling activity occurs rather than hauling the produced water to other disposal sites in the County. No improvements to CR 215 are necessary as a result of this pond. 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 The property is located in a secluded portion of the property which is practically screened by adjacent steep topography. It cannot be seen or heard from CR 215. As noted earlier, the proposed use will have relatively limited impacts to surrounding properties. It is situated in a remote private location on the property such that it is situated at the end of a dead-end county road which is used primarily for industrial traffic serving the existing industrial uses in the area with very limited general population traffic. Further, the site itself is situated in an industrial area already characterized by intense industrial activity from the oil shale exploration / processing activities. No screening is necessary. While no lighting is proposed, any future lighting shall be directed inward and downward towards. Section 5.03.07 (industrial Operations] Pursuant to Section 5.03.07 of the Zoning Resolution, a permit for Industrial Operations requires the submittal of an impact statement on the proposed use describing its location, scope, design and construction schedule, including an explanation of its operational characteristics. The impact statement is required to address the following: (A) Existing lawful use of water through depletion or pollution of surface run-off, streamjlow or ground water. Response The application states that the pond is lined and is designed as a "no discharge" facility and 2 feet of free board will be maintained within the pond so no overtopping should occur. The liner is designed Encana Water Storage Pond BOCC — 05/16/05 Page 6 with a double liner of geosynthetic materials and an internal leak detection and recovery system. The liner will be placed over a 12 -inch thick bentonite (low permeability clay) amended and compacted soil liner. This issue is discussed in greater detail at the end of this report. (B) Impacts on adjacent land from the generation of vapor, dust, smoke, noise, glare or vibration, or other emanations. Response The pumps are to be located within a pump house to dampen any noise generated. The power supply is expected to be electric rather than diesel which will reduce the noise generated considerably. Any noise generated will have virtually zero impact on adjacent properties since the pond is located in a canyon -like area that will prevent any sound from traveling as well as being located well within the boundaries of the subject property far from adjacent properties. Again, the planned equipment buildings will house the pumping equipment which should serve to dampen the noise generated by the pumps. In any event, EnCana shall adhere to the noise standards specified by the Colorado Revised Statutes and the Colorado 011 and Gas Conservation Commission rules. An Applicant is required to demonstrate that the noise generated from the pump does not exceed the levels set out in the statutes which are provided in the matrix below. Further, the Board has also understood that the level that needs to be met is that of the receiving use and not the sender use. The Statute states "Sound levels of noise radiating from a property line at a distance of 25 feet or more there from in excess of the dB(A) established for the following time periods and zones shall constitute (prema facia) evidence that such noise is a public nuisance." The table below shows the zones and dB(A) acceptable for each zone and particular time. Zone 7amto7pm 7pmto7am Residential 55 dB(A) 50 dB(A) Commercial 60 dB(A) 55 dB(A) Light Industrial 65 dB(A) 70 dB(A) Industrial 80 dB(A) 75 dB(A) Since the standard requires that the "volume of sound generated shall comply with the standards set forth in the Colorado Revised Statutes at the time any new application is made. Because the applicant did not provide any information as to the volume of sound generated, this standard is not met. (C) Impacts on wildlife and domestic animals through the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. Response Encana Water Storage Pond BOCC — 05/16/05 Page 7 The site is located within winter rangeland for mule deer, elk, and turkey as identified on t Division of Wildlife's wildlife distribution maps. The Applicant proposes to enclose the pond with a six-foot chain link (wildlife -proof) fence that will preclude roaming wildlife from entering the pond. It should not prevent migration from occurring. No waterfowl deterrent system is presently proposed which prevents waterfowl from becoming resident; however, should the pond attract waterfowl, the Applicant stated that a deterrent system will be installed. Staff referred the application to the Department of Wildlife (DOW) which provided no comments on the proposal. In previous applications, the DOW provided comments such as the following: "Impermeable pond liners make it difficult, if not impossible, for any animals that enter the pond to escape. Escape ramps are essential in facilitating the escape of any wildlife species that manage to reach the water. If one does not currently exist; a simple structure could be constructed in the pond that would allow animals to escape should they become trapped." "The pond should be monitored for oil, and if oil reaches the ponds measures should be taken to immediately remove it. Furthermore, the brackish nature of water commonly associated with oil and gas operations can be detrimental and fatal to waterfowl and other migratory birds. Because of the above information we would suggest that pond netting be installed on the facility to help prevent migratory birds from resting and/or foraging on the ponds, particularly during the winter months." "The applicant should be advised that the death of any migratory bird caused by the proposed facility is a violation of state and federal law. Any deaths of migratory birds or other wildlife attributable to this facility must be immediately reported to the Colorado Division of Wildlife and the United States Fish and Wildlife Service." Ultimately, it appears that the impacts on wildlife through the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions can be adequately mitigated if the applicant follows the guidance of the DOW described above. Staff suggests, should the Board approve the request, that these items above be considered as conditions of approval for the pond. (D) Affirmatively show the impacts of truck and automobile traffic to and from such uses and their impacts to areas in the County. Response The proposed pond is expected to generate an average of 10 water tanker trips and 2 pick-up trips per day into and out of the facility. Most of this truck travel will be coming from and going back to drilling sites on the North Parachute Ranch property on private roads constructed by the industry. Encana Water Storage Pond BOCC — 05/16/05 Page 8 The Applicant states that the pond will reduce the need for more truck hauling water on CR 215 since the pond will be at the property where the drilling activity occurs rather than hauling the water to other disposal sites in the County. No improvements to CR 215 are necessary as a result of this pond. (E) That sufficient distances shall separate such use from abutting property which might otherwise be damaged by operations of the proposed use(s). Response The operations at the facility will not involve any abutting property. The proposed facility will not encroach upon existing setbacks or reduce current separation distances to abutting properties. Staff agrees that the existing facility is located well within required setbacks and is sufficiently separated from adjacent properties in all directions. (F) Mitigation measures proposed for all of the foregoing impacts identified and for the standards identified in Section 5.03.08 of this Resolution Special Use Permits may be granted for those uses with provisions that provide adequate mitigation for the following: (A) A plan for site rehabilitation must be approved by the County Commissioners before a permit for conditional or special use will be issued; Response The application includes a reclamation plan that would govern treatment of the site once the useful life of the facility (20 years) has expired which includes: 1) Removal of all surface equipment and liner material; 2) Restoration and re -contouring of grade to approximate original conditions; 3) Replacement of stockpiled topsoil; and 4) Compliance with all prevailing Colorado Oil and Gas Conservation Commission and Garfield County regulations governing final reclamation. The County Vegetation Manager reviewed the proposal and provided the following comments. 1. Weed Management -The Reclamation Plan does not address post -construction weed management activities. It is requested that the Applicant provide a written commitment to inspect, monitor, and be responsible for the management of any of Garfield County's Noxious Weeds that may emerge on private lands that are disturbed by the construction of the pond. Of particular concern is the berm constructed around the pond. Encana Water Storage Pond BOCC -- 05/16/05 Page 9 2. Revegetation Plan - The applicant shall provide a revegetation plan that includes a plant material list (seed mix with common and scientific names) and a Planting schedule. 3. Revegetation Security - It is the recommendation of this department that the applicant post a revegetation security. The applicant needs to quantify the amount of surface area to be disturbed on private land by the pond construction. Once this is done we will be able to determine an amount for a revegetation security. The security shall be held by Garfield County until vegetation has been successfully reestablished according to the Reclamation Standards in the Garfield County Weed Management Plan. It is the responsibility of the applicant to contact the County, upon successful revegetation establishment, to request an inspection for bond release consideration. (B) The County Commissioners may require security before a permit for special or conditional use is issued, if required. The applicant shall furnish evidence of a bank commitment of credit, bond, certified check or other security deemed acceptable by the County Commissioners in the amount calculated by the County Commissioners to secure the execution of the site rehabilitation plan in workmanlike manner and in accordance with the specifications and construction schedule established or approved by the County Commissioners. Such commitments, bonds or check shall be payable to and held by the County Commissioners; Response In the past, the Board has required, as a condition of approval, that "A sufficient monetary security, determined by the Board of County Commissioners, to ensure rehabilitation of the site once operation has ceased shall be provided by the Applicant." In addition, the Board should be aware that Section 704 of the OGCC rules and regulations regarding proper reclamation of Centralized E&P Waste Management Facilities requires the following: 704. CENTRALIZED E&P WASTE MANAGEMENT FACILITIES An operator which makes application for an off-site, centralized E&P waste management facility shall, upon approval and prior to commencing construction, provide to the Commission financial assurance in the amount of fifty thousand dollars ($50,000) to ensure the proper reclamation, closure and abandonment of such facility. The Application contains such a Performance Bond for $50,000 filed with the COGCC for an E&P Waste Facility. Encana Water Storage Pond BOCC — 05/16/05 Page 10 Section 5.03.08 (Industrial Performance Standards/ Pursuant to section 5.03.08 of the Zoning Resolution, all Industrial Operations in the County shall comply with applicable County, State, and Federal regulations regulating water, air and noise pollution and shall not be conducted in a manner constituting a public nuisance or hazard. Operations shall be conducted in such a manner as to minimize heat, dust, smoke, vibration, glare and odor and all other undesirable environmental effects beyond the boundaries of the property in which such uses are located, in accord with the following standards: (1) Volume of sound generated shall comply with the standards set forth in the Colorado Revised Statutes at the time any new application is made. (2) Vibration generated: every use shall be so operated that the ground vibration inherently and recurrently generated is not perceptible, without instruments, at any point of any boundary line of the property on which the use is located. (3) Emissions of smoke and particulate matter: every use shall be operated so as to comply with all Federal, State and County air quality laws, regulations and standards. (4) Emission of heat, glare, radiation and fumes: every use shall be so operated that it does not emit heat, glare, radiation or fumes which substantially interfere with the existing use of adjoining property or which constitutes a public nuisance or hazard. Flaring of gases, aircraft warning signals, reflective painting of storage tanks, or other such operations which may be required by law as safety or air pollution control measures shall be exempted from this provision. The only permanent noise generated from the facility will emanate from the pumping equipment which will be housed in buildings intended to protect the equipment and dampen the noise generated. EnCana has committed to adhere to the noise standards specified by the Colorado Revised Statutes and the Colorado Oil and Gas Conservation Commission rules. More specifically, the Applicant has committed that the noise will not exceed 75 decibel maximum set out in the statutes. Again, the application did not provide any analysis of noise generated from the facility as it relates to the statutes; however, Staff agrees that the pump building facility will dampen the noise generated so that it will not be detected outside of the property. The proposed equipment buildings will aid in mitigating any minimal vibration, and the vibration, if any, should be localized to a small area immediately surrounding the pumping equipment. If, in the unlikely event, nuisance vibration is detected at any point along the property boundary, additional measures shall be taken to control the vibration. Staff agrees that there will be Iimited vibration that will most likely not be detected at the boundaries of the property. The equipment associated with the pond will add no emissions of smoke and particulate matter. The facility shall be required to comply with Federal, State, and County air quality regulations and standards. There will be some glare by the nature of the water surface; however, it will not be able to impact adjacent properties due to the secluded location of the pond being surrounded by canyon -like steep topography. Encana Water Storage Pond BOCC —05/16/05 Page 11 (5) Storage area, salvage yard, sanitary landfill and mineral waste disposal areas: (A) Storage of flammable or explosive solids or gases shall be in accordance with accepted standards and laws and shall comply with the national, state and local fire codes and written recommendations / comments from the appropriate local protection district regarding compliance with the appropriate codes; (B) At the discretion of the County Commissioners, all outdoor storage facilities may be required to be enclosed by fence, landscaping or wall adequate to conceal such facilities from adjacent property; (C) No materials or wastes shall be deposited upon a property in such form or manner that they may be transferred off the property by any reasonably foreseeable natural causes or forces; (D) Storage of Heavy Equipment will only be allowed subject to (A) and (C) above and the following standards: 1. The minimum lot size is five (5) acres and is not a platted subdivision. 2. The equipment storage area is not placed any closer than 300 ft. from any existing residential dwelling. 3. All equipment storage will be enclosed in an area with screening at least eight (8) feet in height and obscured from view at the same elevation or lower. Screening may include berming, landscaping, sight obscuring fencing or a combination of any of these methods. 4. Any repair and maintenance activity requiring the use of equipment that will generate noise, odors or glare beyond the property boundaries will be conducted within a building or outdoors during the hours of 8 a.m. to 6 pan., Mon. -Fri. 5. Loading and unloading of vehicles shall be conducted on private property and may not be conducted on any public right-of-way. (E) Any storage area for uses not associated with natural resources, shall not exceed ten (10) acres in size. (F) Any lighting of storage area shall be pointed downward and inward to the property center and shaded to prevent direct reflection on adjacent property. Response The size of the entire facility is approximately 3 acres. The Applicant states that there will be no storage of flammable or explosive solids or gases an the property. No increase in the size of the property is associated with the proposed changes. No heavy equipment will be stored on site. Any additional lighting installed at the facility will be installed so that it is pointed downward and inward to the property center and shaded to prevent direct reflection on adjacent property. Encana Water Storage Pond BOCC -- 05/16/05 Page 12 (6) Water pollution: in a case in which potential hazards exist, it shall be necessary to install safeguards designed to comply with the Regulations of the Environmental Protection Agency before operation of the facilities may begin. All percolation tests or ground water resource tests as may be required by local or State Health Officers must be met before operation of the facilities may begin. Response The Applicant states that the facility is designed to protect groundwater and surface water resources and will not generate any adverse impact on water through depletion, pollution of surface runoff, stream flow or surface water. No sewage will be generated, no water supplies will be used and there will be no disposal of water. All water brought to the facility will be contained in above ground storage tanks which shall be contained within adequate secondary containment structures constructed from impermeable materials. Oil and Gas Conservation Commission (OGCC) Rules For background, the following provisions are rules and regulations required by the COGCC which basically point out that 1) produced water is defined as exploration and production waste, and 2) whose disposal is governed by the OGCC and not the Colorado Department of Public Health and Environment (CDPHE). EXPLORATION AND PRODUCTION WASTE (E&P WASTE) shall mean those wastes associated with operations to locate or remove oil or gas from the ground or to remove impurities from such substances, and which are uniquely associated with and intrinsic to oil and gas exploration, development or production operations of which are exempt from regulation under Subtitle C of the Resource Conservation and Recovery Act (RCRA), 42 USC Sections 6921, et. seq. For a waste to be considered an E&P waste, it shall be associated with operations to locate or remove oil or gas from the ground or to remove impurities from such substances and it shall be intrinsic to and uniquely associated with oil and gas exploration, development or production. For natural gas, primary field operations include those production -related activities at or near the wellhead and at the gas plant (regardless of whether or not the gas plant is at or near the wellhead), but prior to transport of the natural gas from the gas plant to market. In addition, uniquely associated wastes derived from the production stream along the gas plant feeder pipelines are considered E&P wastes, even if a change of custody in the natural gas has occurred between the wellhead and the gas plant. In addition, wastes uniquely associated with the operations to recover natural gas from underground storage fields are considered to be E&P waste. SENSITIVE AREA is an area vulnerable to potential significant adverse ground water impacts, due to factors such as the presence of shallow economically usable ground water or pathways for communication with deeper economically usable ground water; proximity to surface water, including lakes, rivers, perennial or intermittent streams, creeks, irrigation canals, and wetlands. Encana Water Storage Pond BOCC — 05/16/05 Page I3 The procedure for identifying Sensitive Areas is set forth in the Sensitive Area Identification Decision Tree and Guidance Document. 704. CENTRALIZED E&P WASTE MANAGEMENT FACILITIES An operator which makes application for an off-site, centralized E&P waste management facility shall, upon approval and prior to commencing construction, provide to the Commission financial assurance in the amount of fifty thousand dollars ($50,000) to ensure the proper reclamation, closure and abandonment of such facility. This section does not apply to underground injection wells and multi -well pits covered under Rules 706 and 707. 901. INTRODUCTION a. General. The rules and regulations of this series establish the permitting, construction, operating and closure requirements for pits, methods of E&P waste management, procedures for spill/release response and reporting, and sampling and analysis for remediation activities. The 900 Series rules are applicable only to E&P waste, as defined in ¢34-60-103(4.5), C.R.S., or other solid waste where the Colorado Department of Public Health And Environment ("CDPHE") has allowed remediation and oversight by the Commission. CRS §34-60-103(4.5) "Explorationand production waste" means those wastes that are generated during the drilling of and productionfrom oil and gas wells or during primary field operations and that are exempt from regulation as hazardous wastes under subtitle c. of the federal "Resource Conservation and Recovery Act of 1976", 42 U.S.C. sec. 6901 to 6934, as amended. 907(c) Produced Water (1) Treatment of produced water. Produced water shall be treated prior to placement in a production pit to prevent crude oil and condensate from entering the pit. (2) Produced water disposal. Produced water may be disposed as follows. A. Injection into a Class II well, permitted in accordance with Rule 325.; B. Evaporation/percolation in a properly permitted lined or unlined pit; C. Disposal at permitted commercial facilities; or D. Disposal by roadspreading on lease roads outside sensitive areas for produced waters with less than 5,000 mg/1 TDS when authorized by the surface owner. Roadspreading shall not result in pooling or runoff of produced waters and the adjacent soils shall meet the allowable concentrations in Table 910-1. Water Quality Monitoring for the Proposal As mentioned earlier, the Applicant states that the liner is designed with a double liner of geosynthetic materials and an internal leak detection and recovery system. No further details were provided as to the design of the system. In previous water storage applications, the Board has required the Applicant to conduct an annual review of the water chemistry contained in the evaporation pit at such time when free standing water is within the pit. This analysis would be submitted to the Building and Planning Department once a year every year the pit is in operation. Encana Water Storage Pond BOCC — 05/16/05 Page 14 The cost of this analysis shall be born entirely by the Applicant. If this water is determined, through this analysis, to be hazardous or toxic based on applicable standards, the Applicant or owner / operator of the facility shall be required to submit an additional SUP to specifically address / mitigate any detected potential hazards. Lastly, it is clear that the COGCC 900 Series Rules are applicable only to E&P waste, as defined in §34-60-103(4.5), C.R.S., or other solid waste where the Colorado Department of Public Health and Environment ("CDPHE") has allowed remediation and oversight by the Commission. As a result, the CDPHE does not regulate water in these ponds. Section 9.03.05 (Periodic Review of SUP/ Pursuant to section 9.03.05 of the Zoning. Resolution: Any Special Use Permits may be made subject to a periodic review not less than every six (6) months if required by the County Commissioners. The purpose of such review shall be to determine compliance or noncompliance with any performance requirements associated with the granting of the Special Use Permit. The County Commissioners shall indicate that such a review is required and shall establish the time periods at the time of issuance of a Special Use Permit. Such review shall be conducted in such manner and by such persons as the County Commissioners deem appropriate to make the review effective and meaningful. Upon the completion of each review, the Commissioners may determine that the permit operations are in compliance and continue the permit, or determine the operations are not in compliance and either suspend the permit or require the permittee to bring the operation into compliance by a certain specified date. Such periodic review shall be limited to those performance requirements and conditions imposed at the time of the original issuance of the Special Use Permit. IV. RECOMMENDED FINDINGS 1. Proper posting and public notice was provided as required for the meeting before the Board of County Commissioners. 2. The meeting before the Board of County Commissioners was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard at that meeting. 3. The above stated and other reasons, the proposed special use permit has been determined to be in the best interest of the health, safety, morals, convenience, order, prosperity and welfare of the citizens of Garfield County. 4. The application has met the requirements of Special Use (Sections 5:03, 5:03:07, 5:03.08 and Encana Water Storage Pond BOCC — 05/16/05 Page 15 9:03) the Garfield County Zoning Resolution of 1978, as amended. V. STAFF RECOMMENDATION Staff recommends that the Board approve the Special Use Permit for "Processing, Storage and Material Handling of Natural Resources" for Encana OiI & Gas, USA with the following conditions: 1. That all representations of the Applicant, either within the application or stated at the hearing before the Board of County Conunissioners, shall be considered conditions of approval unless explicitly altered by the Board. 2. That the operation of the facility be done in accordance with all applicable federal, state, and local regulations governing the operation of this type of facility. 3. That the Applicant shall comply with the fire protection provisions included in the rules and regulations of the Colorado Oil and Gas Conservation Commission (COGCC) and the National Fire Code as the Code pertains to the operation of this facility. 4. The issuance of the SUP shall be subject to an annual review of the water chemistry contained in the evaporation pit at such time when free standing water is within the pit and water samples collected from the ground water monitoring well. These analyses shall be submitted to the Building and Planning Department on the first day of July for every year the pit is in operation. The cost of this analysis shall be born entirely by the Applicant. If this water is determined, through these analyses, to be hazardous or toxic based on applicable standards, the Applicant or owner / operator of the facility shall be required to submit an additional SUP to specifically address / mitigate any detected potential hazards. 5.

MEMORANDUM To: Fred Jarman From: Steve Anthony Re: Comments on the Encana Middlefork Water Storage Facility Date: May 11, 2005 Thanks for the opportunity to comment on this permit. My comments are as follows: 1. Noxious Weeds A. Weed Management -The Reclamation Plan does not address post -construction weed management activities. It is requested that the applicant provide a written commitment to inspect, monitor, and be responsible for the management of any of Garfield County's Noxious Weeds that may emerge on private lands that are disturbed by the construction of the pond. Of particular concern is the berm constructed around the pond. 2. Revegetation A. Revegetation Plan -The applicant shall provide a revegetation plan that includes: A plant material list (seed mix with common and scientific names) Planting schedule. B. Revegetation Security -It is the recommendation of this department that the applicant post a revegetation security. The applicant needs to quantify the amount of surface area to be disturbed on private land by the pond construction. Once this is done we will be able to determine an amount for a revegetation security. The security shall be held by Garfield County until vegetation has been successfully reestablished according to the Reclamation Standards in the Garfield County Weed Management Plan. It is the responsibility of the applicant to contact the County, upon successful revegetation establishment, to request an inspection for bond release consideration.

We've been busy here a the Fire District assisting the family of David Beasley, former Fire Chief, plan for his funeral. The funeral was this morning, which allowed me time this afternoon to run up County Road 215 and look at the site for this pond to be constructed. Upon arrival to the gate, I was instructed by the guard that the pond was straight ahead next to the new compressor station being built. After driving into the old UNOCAL property, 1 drove V mile up the Retort road and looked down over the project. This is what t found -- • The ponds been dug • The ponds been lined • The ponds been graded • The ponds been fenced • The pond has water in it I'm not sure what input you want from the Fire District if the project is already completed? The only real concern we may now have is access and after talking with the security guard at the guard post, she advised me that they work 2417 and have not been advised of an end date. For future projects, the fire control outlined in Part V does not meet the minimum requirement of the Grand Valley Fire Protection District. The Fire District requires tire extinguishers, shovels as well as barren ground for 10 feet around each weld site, as specified in the existing Garfield County Fire Ban Policy. If you have any questions regarding this review, l can breached at the above listed phone number. David A.

'Dense mature riparian vegetation exists along the creeks as they pass through the area. ei Moth of We area near the pond has been denuded by the former oil shale operations and continues to be a location which contains staging areas for heavy -machinery, large crater hauling truck, drilling rigs, pipes, and a compressor station currently under construction. AceeS5 to the propeiy is located at the end of Ctt215 at a locked and manned gate. Project Specifics; 1) The proposed storage pond will serve primarily as a temporary holding pond where produced water generated from natural gas drilling operations in the area can be stored and then reused in drilling operations in the area operated by Enrana. 2) Large water tanker trucks cull haul produced water from drilling sites on the same property to the faulty where the produced water is unloaded into enclosed treatment tanks where separation occurs separating the lighter than water hydrocarbons from the heavier than neater solids/ paraffin/ wastes /oils ("petroleum constituents"). This process allows the solids to be skimmed off and hauled away for disposal while the produced water is pumped directly into the storage pond for reuse in drilrrng operations. 3) The proposed pond will be able to contain approximately 215,000 barrels of produced water at full capacity. The Applicant asserts that this pond wall reduce the need for water hauling trucks to travel Cif 215 to Parachute.

As you are aware, concerns revolving around wildlife, especially bird species, and gas development recycle ponds and the possibility of losses to these species are becoming a more prevalent within our localized region. We agree with the standards and mitigating measures you have proposed to help alleviate and address these concerns. These measures are summarized as follows; 1. The pond lies directly between a compressor station on the East and a storage maintenance yard on the west. The human activity and noise levels from these adjacent areas may lessen the chance of many species being lost to the pond. 2. The pond will be filled with water from a settling tank which will skim and remove oil. 3. The pond will be aerated at high levels and through its entirety, which may also serve as a deterrent to many species. 4. The boundary fence will be maintained, and a chicken -wire type fencing material no wider than 1 inch will be installed from a sub soil depth of no less than six inches and a height of no Tess than three feet. This will help prevent smaller mammals and shore type birds from entering the pond area. 5. A monitoring program will be initiated to ensure these measures are adequate to prevent the Toss of species within the area. If species are being lost, measures will be taken to further prevent the loss of wildlife. Further measures may include netting the pond to prevent loss, which will most likely be the only true prevention method, or other techniques developed with the cooperation of the Division of Wildlife. 6. Encana may also look into obtaining a wash station near the site and obtain the training through the U.S. Fish and Wildlife Service to handle birds which have been contaminated. This measure does not need to be in place in order for Encana to begin utilizing the pond. Thank you for allowing us to make recommendations and work to promote prosperous wildlife populations. We look forward to future cooperation to ensure the prosperity of our wildlife populations. Sincerely Ron Vel:rde Northwest ' e: onal Manager cc.

POND CONSTRUCTION General The 200,000 -barrel capacity Middle Fork Water Storage Pond was constructed by SEM and serves to store produced water from natural gas wells drilled within the NPR property and fresh water from the Colorado River for drilling and completion operations. A small diversion ditch was constructed to capture upstream runoff from the slope on the northwestern edge of the pond and convey it to the existing drainage. The pond is constructed predominantly in cut with a maximum fill height of approximately 10 feet. The pond crest is situated at elevation 5815 feet while the pond floor slopes from elevation 5803 feet to elevation 5802 feet at the pond low point; this results in a pond depth varying from approximately 12 to 13 feet. The pond interior basin slopes were constructed at a 2.5H:1V (horizontal:vertical) slope. According to SEM's letter to EnCana dated July 18, 2005, due to the presence of excess material and to facilitate the revegetation process, the pond downstream fill slopes were constructed at slopes approximating 3H:1V rather than the 2H:1V slope proposed in the design. The pond construction includes a leachate collection and recovery system (LCRS) sump between the primary and secondary geomembrane liners and located at the pond low point along the western edge of the pond floor. An outlet pipe is located just to the north of the LCRS sump to remove water from the pond for use in the operations. The inlet pipe is located on the eastern side of the north slope. A perimeter fence was also installed around the pond perimeter as a safety precaution. Earthworks SEM conducted the earthworks construction for the Middle Fork Water Storage Pond. During construction, the pond area required demolition and disposal of several hundred yards of concrete, rebar, and other unacceptable fill materials. The pond embankment was constructed with random fill material generated from the pond and upstream curt slope excavations. Fill material was dumped in place using a Model 980F Loader and graded to 6 -inch lift thicknesses using the loader and a Caterpillar Model D4C Dozer. Unacceptable materials usually consisting of rock larger than 4 -inches in size encountered during fill placement were removed and disposed of outside the perimeter of the pond. After placement of each 6 -inch lift, the lift was compacted using a Caterpillar Model 433 Vibratory Sheepsfoot Roller. It should be noted that the original density specification for compaction of fill material, proposed in the design, was G:5102500179.051ACTIVESREPORTs\KP\MFWSP REVIEW LETTER REPORT.DOC Knight Piesold CONSULTING 4 Mr. Michael Rynearson August 15, 2005 EnCana Oil & Gas (USA) Inc. replaced with a method specification. We believe this is an acceptable revision given the low embankment, and the complete pond liner system. Following the completion of the embankment, the pond slopes and floor were graded smooth and any protruding rocks were removed. A Caterpillar Model 563 Smooth Drum Vibratory Roller was then run over the interior slopes and bottom of the pond in preparation for the geosynthetic liner. Additionally, as an add-on during construction, a 1.5 -inch -thick layer of powdered bentonite was then spread over the pond interior to act as a cushion layer for the pond liner system. Simultaneous with the pond interior earthworks, the pond crest was graded smooth to within ±0.1 feet of the design grades using a laser level and a Caterpillar Model 140G Motorgrader. After leveling the pond crest, a Mirafi fabric was placed followed by 4 to 6 inches of 3/4 -inch screened rock to act as a wearing course. SEM stated in their July 18, 2005 letter, listed previously, that "the completed construction was done in accordance with the lines and grades shown on the plans. The only change was the exterior fill slopes were changed to 3H:1V from 2H:1V as shown on the plans." Geosynthetics Colorado Lining Construction (CLC) was contracted while Con -Sy, Inc. (Con -Sy) was also subcontracted to CLC to install the geosynthetics in the Middle Fork Water Storage Pond. The geomembrane and geonet used were supplied by GSE Lining Technology, Inc (GSE) while SKAPS Industries supplied a geocomposite cushioning layer for the geomembrane. It should be noted that CLC's project reference list does not list dates, in all cases, to establish their years of installation experience. However, the reference list does demonstrate the company to have sufficient installation experience for the successful completion of this project and thus believe they have demonstrated that they have the requisite experience to meet the intent of the specification. Following placement of the 1.5 -inch -thick layer of powdered bentonite over the pond interior, a SKAPS TransNet HDPE geocomposite 220 was placed on top of the powdered bentonite. The SKAPS TransNet HDPE geocomposite is essentially a geonet sandwiched between geofabric. In summary, the geomembrane liner system for the Middle Fork Water Storage Pond rests above the powdered bentonite and consists of the following: SKAPS TransNet HDPE geocomposite 220 consisting of SKAPS GeoNet made from HDPE resin with a 6-oz/sy non -woven geotextile head bonded on both sides of the geonet 60 -mil GSE smooth HDPE geomembrane (secondary liner) G:1102100179.05V1CTIVEVREPORTSVKPVMFWSP REVIEW LETTER REPORT.COC Knight Piesold CONSULTING 5 Mr. Michael Rynearson August 15, 2005 EnCana Oil & Gas (USA) Inc. • HyperNet geonet (LCRS) • 60 -mil GSE smooth HDPE geomembrane (primary liner) CLC has asserted, in their April 29, 2005 letter regarding the EnCana Oil & Gas Project, the liner "was installed and tested in accordance with the design specifications. The installation and quality assurance testing also meets or exceeded documented industry guidelines and standards." Additionally, the pond subgrade was inspected and accepted in writing by CLC and Con -Sy on March 13, 2005. The pond geomembrane was also approved in writing by CLC and Con -Sy on March 13, 2005. Furthermore, the GSE material certification sheets were inspected along with the peel and shear destruct test and air lance test documentation for completeness. The documentation is in compliance with industry standards. Site Reconnaissance Summary A site reconnaissance was conducted by the undersigned on June 21, 2005 to allow visual inspection of the completed facility. The visible construction was maintained in a professional, workmanlike manner with no apparent problems. The pond crest and downstream slopes were well groomed, and the anchor trench around the pond crest appeared to be well compacted with no loose soil material to indicate movement of the liner. The pond liner had no visible signs of damage to the primary geomembrane, and the welds appeared to be fully and continuously bonded for the lengths of the seams inspected. At the time of the site reconnaissance, there were several feet of water in the facility. Hydrostatic Loading We understand from Mr. Rynearson, through a personal communication on July 28, 2005 with the undersigned, that since the site reconnaissance the pond has been filled twice to approximately 80 percent capacity and that no fluid has been observed in the LCRS, attesting to the liner's integrity. CONCLUSIONS AND RECOMMENDATIONS In our opinion, based on the June 21, 2005 field inspection and review of the reporting documents and design material, the Middle Fork Water Storage Pond was completed in a manner that meets the intent of the plans and specifications. Minor modifications including: (1) use of a method specification for fill placement and compaction rather than a density specification, (2) flattening of the downstream embankment slopes, and (3) inclusion of a cushioning layer beneath the pond secondary geomembrane that have been incorporated into the pond construction are in keeping with and/or enhance the original design.

The Applicant shall comply with the following Industrial Performance Standards in Section 5.08.08 of the Garfield County Zoning Resolution of 1978, as amended including: a) Volume of sound generated shall comply with the standards set forth in the Colorado Revised Statutes. The only industrial source of noise at the Middle Fork Water Storage Facility is a water pump, which is enclosed inside a pumphouse building on-site. The water pump is electric -driven and noise levels are minimal. Current Colorado Oil and Gas Conservation Commission (COGCC) rules require noise compliance at 350 feet from the source in rural areas, unless oil and gas facilities are located on lands owned or leased by the operator, at which point compliance is measured at 350 feet from the source or at the property line, whichever is greater. EnCana has not conducted a noise survey, but believes noise levels are in compliance with this standard, as the property line is approximately one mile south and noise from the electric -driven motor is practically non- existent. b) Vibration generated: every use shall be so operated that the ground vibration inherently and recurrently generated is not perceptible, without instruments, at any point of any boundary line of the property on which the use is located. Minor vibrations occur when the electric -driven water pump motor is operating; however, vibrations are attenuated within the pump house building. EnCana believes vibration levels are compliant with this standard, as the property line is approximately one mile south and noise from the electric -driven motor is practically non-existent. c) Emissions of smoke and particulate matter: every use shall be operated so as to comply with all Federal, State and County air quality laws, regulations and standards. There is no emission of smoke or particulate matter associated with operation of the Middle Fork Water Storage Facility. d) Emission of heat, glare, radiation, and fumes: every use shall be so operated that it does not emit heat, glare, radiation or fumes which substantially interfere with the existing use of adjoining property or which constitutes a public nuisance or hazard. Flaring of gases, aircraft warning signals, reflective painting of storage tanks, or other such operations which may be required by law as safety or air pollution control measures shall be exempted from this provision. There is no emission of heat, glare, radiation, and fumes associated with operation of the Middle Fork Water Storage Facility. I apologize for the delinquent correspondence documenting compliance with the conditions of approval.

(CordiIleran) was contacted by EnCana Oil & Gas (USA), Inc. (EnCana) to provide environmental services in response to the rejection of the Special Use Permit (SUP) application for material handling, processing, and storage of natural resources in the RL Zone district for the EnCana Drill Fluid Recycling Operation on the North Parachute Ranch (NPR). Specifically, this report summarizes the current and historical groundwater quality in the vicinity of the NPR Middle Fork Produced Water Pond. 1.0 Background The NPR Middle Fork Produced Water Pond is located adjacent to the historical Union Oil Company of California (Unocal) Oil Shale Plant. Environmental cleanup and closure activities were completed on the former Unocal NPR property in the late 90's. Closure and cleanup were conducted in accordance with Colorado Division of Minerals and Geology (CDMG) and Department of Public Health and Environment (CDPHE) requirements. However, it is noted that impacts to ground water did occur near the Middle Fork Pond location, were remediated in accordance with CDPHE requirements, and residual amounts of contaminants remained at the time of CDPHE closure acceptance. EnCana acquired the NPR property in 2004 through acquisition of Tom Brown Inc. In April 2005, two ground water monitoring wells were installed to characterize ground water quality hydraulically up -gradient (MW 10) and down -gradient (MWI 1) of the NPR Middle Fork Produced Water Pond. The NPR Middle Fork Produced Water Pond was online and functioning in late June of 2005. Cordilleras Compliance Services, Inc. Grand Junction, CO • Denver, CO • Casper, WY • Laramie, WY Environmental Consulting Engineers and Scientists 2.0 Water Quality Summary The ground water quality monitoring program began on June 14th and 15th, 2005 with the collection of background samples from MW10 and MW11. Sample collection continued quarterly for the remainder of 2005 and through the first quarter of 2006 for both ground water monitoring wells. During the second quarter sampling for 2006, it was discovered that MW11 had been destroyed by construction activities in the area. As a result, samples were only collected from MW10. Replacement of MW11 has been approved and will be conducted in August 2006. Samples were analyzed for dissolved methane; BTEX and MTBE; major anions; alkalinity; sulfide; total dissolved solids; ammonia; total metals; sulfate reducing, iron related, and slime forming bacteria. Ground water quality Data Summary Reports for the samples collected from MW10 and MW11 are included as Appendix A and Laboratory Analytical Reports are included as Appendix B. Samples were handled in accordance with Environmental Protection Agency (EPA) and Cordilleran protocols and procedures for environmental sample handling. The samples were shipped via FedEx to Environmental Science Corporation in Mt. Juliet, TN following strict chain -of -custody protocols. Samples were received in good condition and were analyzed within method required holding times. 3.0 Summary and Conclusions In summary, the ground water analytical results for samples collected during 2005 and 2006 water quality monitoring program are generally consistent with historical data collected before the NPR Middle Fork Produced Water Pond became operational. Examination of current period data in comparison to historical monitoring data, suggest that there has been no statistically significant impact to ground water from activities conducted at the NPR Middle Fork Produced Water Pond.

Q (ESC) Sample held beyond the accepted holding time. T8 (ESC) - Additional method/sample information: Sample(s) received past/too close to holding time expiration. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

Treatment outside of method protocol was required to determine the analytical result. REX(EPA)- Re -prepared: The indicated analytical results were generated from a re -extraction or preparation of the sample. (ESC) Sample held beyond the accepted holding time. (ESC) - Additional QC Info: The sample concentration is too high to evaluate accurate spike recoveries. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference {%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier. Page 19 of 19 ENVIRONMENTAL SCIENCE CORP .

J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low T8 (ESC) - Additional method/sample information: Sample(s) received past/too close to holding time expiration. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

The detection limit is elevated in order to reflect the necessary dilution. (ESC) - Additional method/sample information: Sample{s} received past/too close to holding time expiration. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromatography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

(ESC) Sample diluted due to matrix interferences that impaired the ability to make an accurate analytical determination. The detection limit is elevated in order to reflect the necessary dilution. (ESC) - Additional method/sample information: Sample(s) received past/too close to holding time expiration. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses. Control Limits (AQ) (SS) 2-Fluorophenol 31-119 Nitrobenzene --d5 43-118 Dibromfluoromethane 68-128 64-125 Phenol -d5 12-134 2-Fluorobiphenyl 45-128 Toluene -d8 76-115 69-118 2,4,6-Tribromophenol 51-141 Terphenyl-d14 43-137 4-Bromofluorobenzene 79-127 61-134 TIC - Tentatively Identified Compound: Compounds detected in samples that are not target compounds, internal standards, system monitoring compounds, or surrogates.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier. Page 20 of 20 Cordilleras• ComplianceServices, Inc.

Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "JG". The relative percent difference {$RPD} between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

CO 81635 Mr. Zwierzchowski, i`',1G - 1 2005 For it%rlrllrfc For People This letter is a follow up response to a meeting on May 25`I' , with JT Romatzke in regards to the recycled water development pond on Parachute Creek. As you are aware, concerns revolving around wildlife, especially bird species, and gas development recycle ponds and the possibility of losses to these species are becoming a more prevalent within our localized region. We agree with the standards and mitigating measures you have proposed to help alleviate and address these concerns. These measures are summarized as follows; 1. The pond lies directly between a compressor station on the East and a storage maintenance yard on the west. The human activity and noise levels from these adjacent areas may lessen the chance of many species being lost to the pond. 2. The pond will be filled with water from a settling tank which will skim and remove oil. 3. The pond will be aerated at high levels and through its entirety, which may also serve as a deterrent to many species. 4. The boundary fence will be maintained, and a chicken -wire type fencing material no wider than I inch will be installed from a sub soil depth of no less than six inches and a height of no less than three feet. This will help prevent smaller mammals and shore type birds from entering the pond area. 5. A monitoring program will be initiated to ensure these measures are adequate to prevent the loss of species within the area. if species are being lost, measures will be taken to further prevent the loss of wildlife. Further measures may include netting the pond to prevent loss, which will most likely be the only true prevention method, or other techniques developed with the cooperation of the Division of' Wildlife. 6. Encana may also look into obtaining a wash station near the site and obtain the training through the U,S. Fish and Wildlife Service to handle birds which have been contaminated. This measure does not need to be. in place in order for Encana to begin utilizing the pond. Thank you for allowing us to make recommendations and work to promote prosperous wildlife populations. We look forward to future cooperation to ensure the prosperity of our wildlife populations. Sincerely Jl Ron Vel rde - Northwest Re onal Manager cc.

As part of their over all land management program, EnCana intends to control noxious weeds on the NPR. NAME OF SPECIAL USE PERMIT FACILITY: EnCana Produced Water Pond (PWP). PHYSICAL ADDRESS OF PROPERTY: North Parachute Ranch, Confluence of East Middle and East Fork of Parachute Creek (see attached map, Figure 1). AMOUNT OF INFESTED LAND TO BE MANAGED: Disturbed area of two acres currently has no infestation (see attached Figure 2. Produced Water Pond Site). TARGETED WEEDS: Although not currently found in the PWP site, Table 1 lists weeds observed nearby and those most likely be the subject of future control efforts within the site. The strategies summarized in Table 2 for annuals and biennials and in Table 3 for perennials are those found to be most effective depending on the growth habits of each species, i.e., annual, biennial, or perennial. Table 1. Noxious Weeds observed near the PWP site. Common Name Scientific Name Type* Control Methods Houndstongue Cynoglossum officinale 13 Re -seed with aggressive grasses, removal at flowering or early seed, herbicides at prebud or rosette stage. Common Burdock Arctis minus B Re -seed with aggressive grasses, cut or dig rosettes, herbicides. Salt Cedar Tamarix ramosissima and T. parviflora P Repeated flooding, hand pull seedlings, herbicides on stems of young plants, cut mature plants and herbicide treat stumps within 30 minutes, shade intolerant, promote growth of native riparian shrubs and trees. Thistle, Canada Cirsium arvense P Re -seed with aggressive grasses, mow every 2-3 weeks over 3 growing seasons, or mowing followed by fall herbicide application, or beetles, or herbicide in late summer or fall. Thistle, Scotch Onopordum acanthium B Mechanical by tillage, hand grubbing; mowing at bolting, herbicides at rosette stage. Table 1. Noxious Weeds observed near the PWP site. Common Name Scientific Nance Type* Control Methods Whitetop, Hoary Cress Cardaria draba P Herbicides during bud stage or early flowering is the most effective control method. * B = biennial, P = perennial Table 2. Treatment strategies for annuals and biennials. ANNUALS & BIENNIALS Target: prevent seed production 1) Hand grubbing (pulling), hoeing, tillage, cultivation in rosette stage and before flowering or seed maturity. 2) Chop roots below soil level. 3) Herbicide treatment in rosette or bolting stage, before flowering. 4) Mow biennials after bolting stage and before seed set; mowing annuals may not prevent the plants from flowering. Table 3. Treatment strategies for perennials. 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 first emerging in spring but allow to grow to bud/bloom stage. 2) Herbicide treatment at bud to bloom stage or in the fall. In the fall plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time. If the weed patch has been there a long time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in the fall will kill the following year's shoots, which are being formed on the roots at this time. 3) Mowing usually is not recommended because the plants will flower anyway; seed production may be reduced, however. Many studies have shown that mowing perennials and spraying the regrowth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its biology. CURRENT AMOUNT OF INFESTED LAND TO BE MANAGED: -0- at this time in PWP permit area. DESCRIBE THE AREA TO BE TREATED: The area to be monitored and treated as necessary is approximately 2.0 acres (Figure 2. Produced Water Pond Site.). METHODS OF TREATMENT: Re -vegetation. Disturbed areas were immediately re -seeded with the following mix: Seed Mix Applied to PWP Site. Scientific Name Common Name Variety Application Rate lbs/acre Pascopyrum smithii western wheatgrass 6 Elytrigia intermedia trichophorum pubescent wheatgrass Luna 3 Bromus inermis smooth brome 3 Medicago sativa alfalfa Ladak 6 Astragalas cicer cicer milkvetch 2 TOTAL 20 Follow up seeding needs may become evident during monitoring and if so identified, these needs will be communicated to management to provide for re- seeding. Monitoring. Monitoring for targeted weeds should commence once weekly at lower elevations between March 1 and April 1 depending on spring weather annually through the growing season. Disturbed areas have been re -seeded and no weeds were detected in the Special Use Permit area during an inspection by WestWater biologists on May 26, 2005. Monitoring by qualified personnel will be conducted using Table 4 as a general guide to best control periods. Mechanical. Observed weeds will be controlled first by mechanical means, primarily hand grubbing or pulling. Internal pond banks are covered by the pond liner which physically prevents weed establishment within the lined area. Control of listed species in nearby disturb areas is recommended to reduce the risk and rate of infestation. Chemical. Spot treating is recommended in areas immediately adjacent to the PWP site for the purpose of reducing risk of infestation. If necessary spot treatment will be conducted in the PWP site as well as the surrounding areas, particularly the nearby pipeline corridor. Chemicals recommended include synthetic auxin growth regulators (e.g., 2,4D; tordon, banvel, and garlon), EPSP synthase inhibitors (e.g., glyphosate) or a mix of these. For whitetop an ALS inhibitor such as metsulfuron methyl has been found to be most effective. In all cases, the certified applicator shall deem which chemical(s) and at what concentration(s) shall be used at the time of application. However, it is anticipated that the aforementioned classes of chemicals will be first choice of most certified herbicide application contractors.

ADDITIONAL INFORMATION: As mentioned in the introduction, an Integrated Weed Management Plan for the entire North Parachute Ranch is being prepared. This includes weed inventory of all portions of the NPR. Table 4 (attached) is a guide to timing of key biological processes and the best growth stage to control the subject species on an annual basis.

NPR Reclamation Plan 1 May 2006 Upper Zone The Upper Zone receives 16 to 25 inches of annual precipitation. A majority of the annual precipitation is received during non -growing season (late fall/winter). Prirag plant communities. in the Upper Zone are Mountain Big Sagebrush/Wheatgrass and Upland Deciduous ShnibfWheatgrass shniblands with smaller occurrences of Aspen and. Douglas Fir forests and riparian shrub, tree and wetland. habitats. The plant corn unities in the Upper Zone have the' greatest diversity of plant species. Most of these species: have adapted-mechanist/1s for establishment and survival in the: presence of the competition exerted by other species in the community: These;communities are dominated -by` shortrtlivedcool season bunch grasses, which are .an important factor in providing interspaces for establishment and maintenance of for bs and shrubs bs° within the corninun ty.

RECLAMATION .CHALLENGES AND AVOIDANCE RECOMMENDATIONS North Parachute Ranch presents extreme reclamation challenges from a broad array of climate and geomorphological factors inherent to the site. These factors- often act synergistically and increasethe negativo effects exponentially ' -These factors include: • Steep slopes and potential for soil movement. Effective ;soil -moisture issues including timing of seeding to coincide with natural precipitation, o Difficulty in re -contouring to blend with extreme slopes: of natural topography. • Thin soils due to infertility from slope, exposure and soilsource: materials: • Slumps (instability, difficulty in holding slopes). • Difficulty preventing establishment of noxious weeds in disturbed land. • Riparian areas especially -these dominated by mature cottonwoodslbox-elderishrubs (due to wildlife and water quality Jalue and long-term needed to establish large trees). Such areas, ifdisturbed, are very likely to require more time and expense to'effectively reclaim. For.:example, riparian woodland and shrubland disturbances, may installation of live plant materials in the. form of containerizedtrees and shrubs. Installation and three years of careful oversight and watering cif thesewoody species to insure survival is,far more costly titan disturbance on sites, which can be successfulIy re -seeded In addition to susceptibility to erosion;.and-sediment problems, difficult, listednox ous weeds also present a reclamation challenge ofhuge proportions. For these reasons, it is recommended. livestock;grazing be postponed indefinitely. Canada thistle on theWest-Fork and houndstongue onie East Fork seriously threaten riparian plant coirtmunitics Both problettns are exasperated by :ingof livestock.:upstream from,.NP::property .

Replacement of topsoil should occurlustprior te-re-seeding to prevent early germination and establishment of highly competitive annual weeds. In nearly all cases, re -vegetation should occur as gdickly'as possible NPR Reclamaticn Plan 5 May 2006 after topsoiling, in order to maintain soil nutrients and microbe levels, discourage weed invasion, and control erosion. R -seeding should be timed to coincide immediately prior to the; season of greatest precipitation, tate falUwinter; Seed of many native plant species require a period of freezing temperatures prior to germination which ensures the seed will germinatein spring when soil moisture conditions are optirnuin for establishment and survival of the seedling. Also, several native species, such as big sagebrush, -begin their slow germination process under snow cover Ideally, topsoil replacement should occur in late August and September followed by:re.seeding In late September to early December_prior:to fre°ezing.soiI surface. If''re=vegetationoccurs too. early, seeds are subjected to unnecessary exposure to seed.predators and spoilage, if it occurs:too late (spring planting), seeds and plants may encounter insufficient moisture to geminate or to survive after germination, and will be faced with higher competition from annual weeds. Topsoil Handling Proper handling and storage of topsoil is critical to successful re -vegetation, especially in the case of re-establishing important native plant species on disturbed areas. The topsoil contains soil: microbes (bacteria, mrcorrhiza, invertebrates) and seed banks of viable seed for the native plants present, on the site. Many native plant species depend upon the activity of soil -microbes for germination in some instances arid for establishand survival of most seedlings. Topsoil•is_usualy stripped from a site and stored in the smallest place possible in deep, unstable piles. Stockpiling topsoil in deep, unstable piles for long periods (over 30 days) results ill the loss or limitaton of topsoil microbes, and= viable seed. This is especially so where°soils are stockpiled more than several feet in: height and"`biological activity is_diminished:from lack of oxygen. Topsoil should be;protected from erosion and weed invasion Topsoil should be stockpiled in piles no deeper than 2 feet with stable slopes;>and be positioned to minimize exposure to wind and veer erosion. Topsoil piles stored forlonger than 0 days shouLd be m ediately seeded. to provide cover to reduce 0r(0o, provide competition for weed species,,and to::maintain viability ofthe soil fungi and microbe communities Several' fastgerrninating sterile cover crops - 4 . , ("ftegreen" and "Quickguard");arecommercially available that should be'used'for shortperiod storage oftopsoil: Topsoil stored for morelhan one growitig$eaonrshOtild be seeded with one of the recornmendcd seed; mixesbased upon the zone the, site'is in. Using the recommended seed mixes on long term storage piles will help marntain;biolagieal.activity and provide a seed bank of viable, seed., Iflong-term stockpiling or deep stockpiling can not beavoided, application of micorrhizal inoculants (see section below)lmay be beneficial. Use of Fertilizer Use of fertilizer should not be used in the reclamation of acid or semi -arid sites. These areas are typically at high risk ofinvasion by exoticannual weeds, almost all of which are favored -by higi er levels of nitrogen. Nativewestern-species are well adapted 10, the low fertility of soils in these areas. There are many cases of severe weed :infestations, which are directly attributable to NPR Reclamation Plan G May 2006 addition of nitrogen. In addition to the considerable cost incurred, the routine use of fertilizer may well trigger problems with undesirable annual invaders, which can be essentially impossible to correct, Use of Mulch Mulch should be used only where there are specific indications for its.. application., and not as a routine element in reclamation. Itmay be useful in wetter areas or on extremely steep areas where severe erosion potential exists. On drier upland areas tlere:are a number of potential problems. These-inalude, wicking,of soil moisture<leadingto increased evaporation, alteration of carbon: nitrogen ratios, attraction of rodent and irivertebrates;to seed and seedling predators; and plant competition from grain or weed seeds in the mulch. Where mulch is used, it is imperative that it beretained either by mechanical crimping, application of a tackifier, or with netting: These materials and the time required for theirapplication add substantially to reclamation costs. Use of Certified Seed The two types of certified seed are"Blue Tagged Certified Seed" and "Yellow Tagged Source. Identified Seed": Certified Seed (Blue Tag): Seed Certification is the means of maintaining the pedigree (genetically pure seed) of a specific variety .of seed. Each state has a seed certifyirng agency ° or crop improvement association- that certifies seed, Blue Tagged. Certified Seed must meet high purity and. gertninationstandards andhave a low weed content,:usually less than 0.2j percent: Blue tagged ed certified seed cannot contain a` � . ,any proliiibtted noxious,weeds ofthe state of `. certification. Many native species are -now available in certified cultivarsand in most cases the cert fied cultivars are lower cost., Source: Identified Seed,(Yellow Tag)-; There is-astrong maricet.for native plantnnaterals,: but therenay not be certified ecotypes available due -to lack of breeding, low supply; or high cost to produ, oru ireliableciernand tn:most cases,<native plant'materiai should be acquired from harvest areas with thie same or higher latitude. of the; area of intended use State seed laws only require that the actual state of origin be on the label To receive seed from the area you designate,. it advisable to request_"Source Identified, Seed» in order: to ensure that a certification agency has verified the'exact lot' atio t'front which the seed_was harvested Source identified :certification is;in place in Colorado; New Mexieo, Utah, Wyoming and Montana. Yellow tags do not guarantee that the seed is free of noxious weeds: Buyers should refer to the vendor's Iabel°fer analysis:and weed content,, or better -yet, test the.seedthemselves: Ilarvest ng Local Seed Plant species commonly display considerable site,adaptation and: variability. Thus seed collected far from its eventual planting site omen does less well than, seedofthe same species collected closer -to the planting site. Most professional seed suppliersrecord the collection site,and it may be possible to choose seed that is from locally adapted plants. If such seed is not available, the, possibility of contractngwith'collectors to obtain local seed should be investigated. NPRReclaniation Plan 7 May 2006 Seed Testing Testing seed is the only way to insure the quality of the seed (purity and viability) and that no undesirable species are present Purity tests will show the percentages of crop, weed and inert matter (material other than seed such as stems or chaff), and show if the percentage of each species in the mix meets the standards ordered. The terns germination and viability are g ya g germination l sometimes used interchan eabl but,do rrat have the same rneanin�..A test Will determine.how seeds perforin under favorable conditions; However, some seeds are dormant and do Oa germinate even though they are still alive. Dormant seeds: have the potential to germinate if dormaney is broken, usually through time and/or physiological stimulus; A viability -test will. slew the "sum of thepercent germinated and percent dormant seeds' ina seed lot, providing information on the potential germination of the lot. Proper seed sampling is very important. The test results receivedcan be no better than the sample sent in Samples should be sent to a seed lab that tests according to the standards established by the National Association of Official Seed Certification Analysts. Inoculation ofLegumes Most legume seeds should be treated with commercially available Rhizobium inoculants to ensure ,that they are: able to make best advantage of their capabilities for nitrogen-xation. Legumes.;included in seed mixes are; American Vetch, Cicer's Millcvetch, Sainfoin; and Utah. SWeetveteh. Inoculation of Sterile Sails Arbuscular-mycorrhiza (fungi) are components of live topsoil and form symbiotic relationships. with plant :roots. There are two types and they, are;:especiaily critical for_ -plants in, infertile, soils or drought'=prone areas such as those found on NPR, In most eases on NPR, en_dornycorrhiza should be used to.inoculate-the ;: soil. since this is the type o. f fungi that associates with= herbaceous arid broadleafed woody plants xf coniferous species such as pinyon puce, Utah juniper, or Douglas fir are proscribed in rectantation, an ectomycorrhizal fungi would *o. be desirable.: improperly stored topsoil. and areas with little or no topsoil ShouRt be treated with c ommercial mycoxrbiza (Barrow,19°95). Mycorriihtzal inoculau is areavailai le in two forms:as':a ni lar form for application during seeding, and as a powder for coating of seeds prior to seeding:, Granular forms are typically applied at a rate of 20 lbs/acre and powder inoculents are applied to the seed at a rate of 1. lbs/acre. When broadcast seeded, the.;granular fortn must be incorporated into the soil with seed by harrowi:. Determination of Pure Live Seed (PLS) Ratio Before a seed application rate can be determined it is necessary to determine the percentage of pure live seed (pis) in the supplied seed Seed may 'contain-weeu seed, seed:ofother species, chaff, satdrand other inert material, and broken seeds PLS equals the percent purify times the percent:. germination Most species are sold on a PLS basis, with the price adjusted accordingly. When given a choice between buying on a PLS or bulk basis, PLS isalways preferable, Less. NPR Reclamation Plan 8 May 2006 expensive seeds with lower purity and germination may actually cost more on a PLS basis than more expensive seed. SEED MIXTURE RECOMMENDATIONS The following sexed mixtures include native grasses that 1.) provide good soil protection, 2) are not overly competitive to allow native'forbs and shrubs to repopulate disturbed areas, and; are commercially-availablein quantities for small acreage projects Mountain big `sagebrush is not included in the -mixture as it is expected to repopulate disturbance from undisturbed stands (anticipated disturbances -are small/linear)::Sagebrush also requires a different seeding strategy (broadcast, on frozen soil or on early snow cover,); . Activities that result in removal of areas greater than 5 acres ofsagebrush, and are not within 100 feet of sagebrush to provide seed source may need to have sagebrush included in the seed mixture. 2ec©rnmfended Seed Minx for,.

As part of their over all land management program, EnCana intends to control noxious weeds on the NPR. NAME OF SPECIAL USE PERMIT FACILITY: EnCana Produced Water Pond (PWP). PHYSICAL ADDRESS OF PROPERTY: North Parachute Ranch, Confluence of East Middle and East Fork of Parachute Creek (see attached map, Figure 1). AMOUNT OF INFESTED LAND TO BE MANAGED;, Disturbed area of two acres currently has no infestation (see attached Figure 2. Produced Water Pond Site). TARGETED WEEDS: Although not currently found in the PWP site, Table 1 lists weeds observed nearby and those most likely be the subject of future control efforts within the site. The strategies summarized in Table 2 for annuals and biennials and in Table 3 for perennials are those found to be most effective depending on the growth habits of each species, i.e., annual, biennial, or perennial. Table 1. Noxious Weeds observed near the PWP site. Common Name Scientific Name Type* Control Methods Houndstongue Cynoglossum ofcinale B Re -seed with aggressive grasses, removal at flowering or early seed, herbicides at prebud or rosette stage. Common Burdock Aretis minus B Re -seed with aggressive grasses, cut or dig rosettes, herbicides. Salt Cedar Tamarix ramosissima and T. parviflora P Repeated flooding, hand pull seedlings, herbicides on stems of young plants, cut mature plants and herbicide treat stumps within 30 minutes, shade intolerant, promote growth of native riparian shrubs and trees. Thistle, Canada Clrsium arvense P Re -seed with aggressive grasses, mow every 2-3 weeks over 3 growing seasons, or mowing followed by fall herbicide application, or beetles, or herbicide in late summer or fall. Thistle, Scotch Onopordum acanthium B Mechanical by tillage, hand grubbing; mowing at bolting, herbicides at rosette stage. Table 1. Noxious Weeds observed near the PWP site. Common Name Scientific Nance Type* Control Methods Whitetop, Hoary Cress Cardaria draba P Herbicides during bud stage or early flowering is the most effective control method. * B = biennial, P = perennial Table 2. Treatment strategies for annuals and biennials. ANNUALS & BIENNIALS Target: prevent seed production 1) Hand grubbing (pulling), hoeing, tillage, cultivation in rosette stage and before flowering or seed maturity. 2) Chop roots below soil level. 3) Herbicide treatment in rosette or bolting stage, before flowering. 4) Mow biennials after bolting stage and before seed set; mowing annuals may not prevent the plants from flowering. Table 3. Treatment strategies for perennials. 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 first emerging in spring but allow to grow to bud/bloom stage. 2) Herbicide treatment at bud to bloom stage or in the fall. In the fall plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time. If the weed patch has been there a long time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in the fall will kill the following year's shoots, which are being formed on the roots at this time. 3) Mowing usually is not recommended because the plants will flower anyway; seed production may be reduced, however. Many studies have shown that mowing perennials and spraying the ,regrowth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its biology. CURRENT AMOUNT OF INFESTED LAND TO BE MANAGED: -0- at this time in PWP permit area. DESCRIBE THE AREA TO BE TREATED: The area to be monitored and treated as necessary is approximately 2.0 acres (Figure 2. Produced Water Pond Site.). METHODS OF TREATMENT: Re -vegetation, Disturbed areas were immediately re -seeded with the following mix: Seed Mix Applied to PWP Site. Scientific Name Common Name Variety Application Rate lbs/acre Pascopyrum smithii western wheatgrass 6 Elytrigia intermedia trichophorum pubescent wheatgrass Luna 3 Bromus inermis smooth brome 3 Medicago sativa alfalfa Ladak 6 Astragalas cicer cicer milkvetch 2 TOTAL 20 Follow up seeding needs may become evident during monitoring and if so identified, these needs will be communicated to management to provide for re- seeding. Monitoring. Monitoring for targeted weeds should commence once weekly at lower elevations between March 1 and April 1 depending on spring weather annually through the growing season. Disturbed areas have been re -seeded and no weeds were detected in the Special Use Permit area during an inspection by WestWater biologists on May 26, 2005. Monitoring by qualified personnel will be conducted using Table 4 as a general guide to best control periods. Mechanical. Observed weeds will be controlled first by mechanical means, primarily hand grubbing or pulling. Internal pond banks are covered by the pond liner which physically prevents weed establishment within the lined area. Control of listed species in nearby disturb areas is recommended to reduce the risk and rate of infestation. Chemical. Spot treating is recommended in areas immediately adjacent to the PWP site for the purpose of reducing risk of infestation. If necessary spot treatment will be conducted in the PWP site as well as the surrounding areas, particularly the nearby pipeline corridor. Chemicals recommended include synthetic auxin growth regulators (e.g., 2,4D; tordon, banvel, and garlon), EPSP synthase inhibitors (e.g., glyphosate) or a mix of these. For whitetop an ALS inhibitor such as metsulfuron methyl has been found to be most effective. In all cases, the certified applicator shall deem which chemical(s) and at what concentration(s) shall be used at the time of application. However, it is anticipated that the aforementioned classes of chemicals will be first choice of most certified herbicide application contractors.

ADDITIONAL INFORMATION: As mentioned in the introduction, an Integrated Weed Management Plan for the entire North Parachute Ranch is being prepared. This includes weed inventory of all portions of the NPR. Table 4 (attached) is a guide to timing of key biological processes and the best growth stage to control the subject species on an annual basis.
