INTRODUCTION ' This permit is for the regulation of stormwater runoffrom constt'ttction activities, and specific allowable non- stormwater discharges in accordance with Part 1.D.3 of the permit. The term "constntction activity" includes ground surface disatrbing activities, including, but not limited to, clearing grading dcwation, demolition, installation of new or improved haul and access roads, staging areas, stoc@iling ofJill materisls, and bonow areas. "stormwater" is precipitation-induced surface ntnoff. This rationale will aplain the background of the Stormwater program, activities which are covered under this permit, how to applyfor coverage under this permit, and the requirenents of this permit. The forms discussed in the rdionale and permit are availablc on the Water Qudtty Control Division's website at: www.cdp he.state co-udw q/Pe ftn itsUnit II. CHANGES IN TTIIS GENERAL PER,VIT Several notable changes from the previous General Permitfor Construction Activities have been incorporated into this permit. Significant changes are listed below. Numerous other minor changes were madefor claification purposes only. A. Authoritv to Discharse This section has been restnrctured to list all of the types of activities covered by this permit, and to be consistent with the definition of "constntction activity." The definition of constrztction activity has been expanded to provide claification. See Part I.A.I of the permit. ( PARTII Paodrt-Page24 PermitNo. COR-030000 II. CIANGES IN THIS GENERAL PERMIT (cont.) ';r: B. Authoitv to Discharse - Oil and Gas Construction This section has been added, to take into account a regulatory change. Thefederal Energt Policy Act of 2005 aempts nearly atl oil and gas constrttction activities from federal requirements under the Clean Water Act's NPDES stormwater discharge permit program. In January 2006, the Colorado Water Quality Control Commission held a hearing to determine what effects, dany, the change infederal law would have upon Colorado's stormwater regulations. The Commission determined that oil and gas construction sites in Colorado that disturb one or more acles are still required to be covered under Colorado's stormwater permitting regulations (Colorado Discharge Permit System (CDPS) regulations (1CCR 1002-61))- In practice, oil and gas construction sites have the same requirements under this permit as do other types of constntction. However, this permit contains some references to the federal Clean Water Act; generally these references are not applicable to oil and gas construction sites to the extent that the references are limited by the federal Energt Policy Act of 2A05. See Part IA.I ft) of the permit. C. ApolicationReouirements The pennit application requirements have changed slightly, including the addition of an email address, if available. See Part 1.A.4(b1. The applicant must be either the owner and/or operator ofthe constuction site. An operator at a cowtruction site that is not covered by a certiJication held by an appropriate entity moy be held liable for operating without the necessary permit coverage. D. Temporarv Coverate \.-il E. F. Part 1.A.5(d) of the previous permit ($ective July l, 2002) dealt with temporaily covering afacility under the general permit even if an individual petmit is more appropriate. This permit section essentially duplicated the previous section (see Part 1.A.5(c)), and so it has been deleted. Reassignment of Permit Coveraqe Procedures have been added to clarify the requirementsfor the transfer ofcoverage ofspecilic portions ofa permitted site to a second party. See Section YIil.I.3 of the rationale and Part IA.8 of the permit. Individual P ermit C iteria This section has been modified to include siuations involving a Toal Maximum Daily Load (TMDL). See Part I.A.I1 of the permit. Stormwater Manasement Plan (SYFMP) The Stormwater Management Plan section has bem divided into two parts: Stormwater Management Plan (SWMP) - General Requirements, which provides the basic framework and general requiremettts for the SWMP, and Stormwater Management Plan (SWMP) - Contents, which specifically identifies each itern that must be addressed in the SWMP. See Parts I.B and I.C of the permit. Stormwater Manasement Plan (SWMPI - General Reauirements The SWMP General Requirements section has been modified to require that the SWMP be updated in accordance with Patts 1.D.5(c) and 1.D.5(d) of the permit (SWMP Review/Changes). This additional requirement ensures that the SWMP provisions reflect cutent site conditions. See Part LB.2(c) of the permit. G, H. (, "- \- t_I!.\1IJEra,\\ I PART II Permit - Page 25 Pernrit No. COR-0300O0 I. CIL{NGES IN THIS GENERaL PERWT (cont.) L Stormwater Manasement Plan (SWMP) - Contents The SWMP Contents section has been modified. Some of the chonges are limited to organization of information, which does not require modification of an *isting permittee's cttrrent SWMP. Most of the SWMP changes involve either clarifications, reformatting or taking recommendations from the Division's SWMP guide and making them permit requirements (e.g., vehicle tracking controls, BMP installation specifi.iations). If an uisting permifiee (La, those with permit coverage before fune i0, 2007) followed the recommendations in the SWMP guide (Appendix A of the permit application), then their SWMP will presumably meet the new requirements. However, for any acisting permittees who did noLlfollow the applicable SWMP guide recommendatioru, their SMWP must be amended to include the new required items: -SWMP Administrator -Identification of potential pollutant sources -Best Manogement Practices descriptions and installation specifications, including dedicated concrete or asphalt batch plants; vehicle tracking control; and waste tnanagement and disposal (including concrete washout activities). For existing permittees, any SWMP changes based on the change in permit requirements must be completed by October i, ZOOZ- The plan is not to be submined b the Division unless requested, but rnust be available on site as outlined in Pan 1.D.5(b) of the permit The BW requirement clarifications included in this renewed permit in no way imply that adequate BMPs to address all pollutant sources at a pertnitted site were not required in previous permits. The revised requirements are intended only to better clarify SWMP content requiretnents and provide improved direction to Pennittees. The SWMP changes are listed below. All new applicants (afier June 30, 2007) for permit coverage for their sites mustfully comply with the new SWMP organization, plan requiremenE, and implementation. l. SiU Description: The requirement to provide an estimate of the run-offcoeficient has been removed. The run-offcofficient as carrently utilized in the SWMP may not contribute suficiently to permit compliance ta justify the effon in determining accfrrate values. See Part 1.C.1 of the permit. However, the Division still encourages use of the coeficient as needed to adequate\t evaluate site-specifi-c BMP selection and design criteria (e.g., pond capacities, BMP location, erc.) See Section C.2 of the SWMP guidance (Appendix A of the permit application). 2. Site Map: The requirement to identify boundaries of the Ll}-yearJlood plain has been removed. The boundaries as carrently utitbed in the SWMP mq not contribute sufficiently to permit compliance to justifi the effort in determining their location. See Part 1.C.2 of the permit. 3. Stormwater Management Controls: This section has been rnodified to require identification of a SWMP Administrator and all potential pollutants sources in the SWMP. See Part 1.C.3 of the pennit- a) The SWMP Administrator is a specific individual(s), position or title who b responsiblefor the process of devetoping implementing maintaining, and revising the SWMP. This individual serves as the comprehensive point of contactfor all aspects of thefacility's SWMP. This requirement may necessitate changes to uisting permittees' SYMPs- PART II Permit - Page26 PermitNo- COR-030000 II. CHANGES IN THIS GENERAL PERMIT (COnt) Ihe requirement to identifu Potential Pollutant Sources has been expanded to include more details for the evaluation of such sources. This evaluation allaws for the appropriate selection of BMPs for implementation at a facility or site. Additionally, this section was added n be consisteflt with the SWMP guide. This requirement may necessitate changes to uisting permittees' SWMPs. Best Managernent Practices @MPs) for Stormwater Pollution Prevention: This sectian was modified to require thefollowing items to be addressed in the SWMP. These requiremenb may necessitate changes to *isting permittees' SWMPs. This section also requires thot the SWMP provide installation and implementation specificationsfor each BMP idmrtfied in the SWMP. For strucfital BMPs, ifl most cases, this must include a technical drawing to provide adequate installation sp ectJicatio ns. See Part I. C. 3 (c). , Dedicated concrete or asphalt bateh plants. This section requires that the practices used to reduce the pollutans in stormwater discharges associated with dedicated concrete or asphalt batch plants be identified in the SWMP. (Coverage under the construction site SWMP and permit is not requiredfor batch plan* if they have alternate CDPS permit coverage.) ii) Vehicle tracking control. This section requires that practices be implemented to contol sedimentfrom vehicle tracking, and that all such practices implemented at the site be clearllt described in the SWMP. Waste management and disposal. This section requires that the pructices implemented at the site to contol stormwater pollution from construction site waste, including concrete washout activities, be clearly described in the SWMP. It also requires that concrete washout activities be conducted in a manner that does not contribute pollutants to surface waters or storrnwater ranoff. Concrete Washout Water. Part 1.D.3(c) of the permit has been revised to conditionally authorize discharges to the ground of concrete wash waterfrom washing of tools and concrete mixer chutes when appropriate BMPs are implemented. The permit prohibits the discharge of concrete washout water to sutface waters and to storm sewer systems. Part 1.C.3(c)(7) of the permit requires that BMPI be in place to prevent surface discharges of concrete washout waterfrom the site. The use of unlined pits to contain concrete washout water is a common practice in Colorado. The Division has further evaluated the need for a permit for discharge of concrete washout water to the ground. The Division has determined that the use of appropriate BMPs for on-site washing of tools and concrete mixer chutes would prevent any significant discharge to groundwater. BMPs to protect groundwater are required by Part 1.C.3(c)(7) of the permit- Because pH is a pollutant of conternfor washout activities, the soil mwt have adequate buffering capacity to result in protection of the groundwater standard, or a liner/contaiilment must be used. The following management practices are recommended to prevent an impactfrom unlined pits to groundwater: (1) the use ofthe washout site should betemporary (ess than I year), and (2) the washout site should be not be located in an area where shallow groundwater may be present, such as near natural drainages, springs, or wetlands. b) c) iii) iv) {,r -t (- il.

Where adequate management prdctices are notfollowed to protect groundwater quality, the Departrnent may require discharges to unlined pits to cease, or require the entity to obtain alternate regulatory approval through noticefrom either the Water Quality Control Division or the Hazardous Materials and Waste Management Division. In addition, Part I.D.

Part 1.D.3(d) of the permit has been revised to conditionally authorize discharges to the ground of waterfrom constraction dewatering activities when appropriate BMPs are implemented. The permit does not authorize the discharge of groundwaterfrom construction dewateing to surface waters or to storm sewer systems. Pan 1.C.3(c)(8) of the permit requires that BMPs be in place to prevent surface discharges. The permittee may apply for coverage under a separate CDPS discharge permit, such as the Construction Dewatering general permit, if there is a potential for discharges to ,turface waters. The Division has determined that potential pollutant sources introduced into groundwater from consaaction dewateing operations do not have a reasonable potential to result in acceedance of groundwater standards when the discharge is to the ground. The primary pollutant of concern in uncontaminated groundwater is sediment. Although technologt- , based standards for sediment do exist in 5 CCR 1002-41, the discharge of sediment to the ground as part ofconstntction dewatering does not have the reasonable potential to result in transport of sediment to the groundwater table so as to result in an *ceedance of those standards. For a discharge of water contaminatedwith other pollutants that are present in concentrations that may cause an exceedance ofgroundwater standards, separate CDPS discharge permit coverage is required- Contaminated groundwater may include that contaminated with pollutants from a landf.ll, mining activit-v, industrial pollutant Plume, underground storage tanh or other source ofhuman-induced groundwater pollution and exceeding the State groundwater standards in Regulatiow 5 CCR I 002-4 I and 42. J. Terms and Conditions. General Limitations and Desisn Standards This section reiterates the requirement thatfacilities select, install, implement, and maintain appropiate BMPs, following good engineering hydrologic and pollution control practices. In addition, requirements for protection of water quality standards (see Part I.D.l.(a) of the permit) and requirements to adequately design BMPs to prevent pollution or degradation of State waters (see Pan 1.D.2 of the permit) have been revised and arefully discussed in Part III.B of the rationale, below- Additional language was also added to Section IILB of the rationale further clarifiing the expectations for compliance with this permit. 1. Management of Site Waste This section has been modiJied to clarify that on-site waste rnust be properly managed to Prevent potential pollution of State waters, and that this permit does not authorbe on-site waste disposal. Solid waste disposal is regtlated by the Hazardous Materials and LVaste Management Division. PARTII Permit - Page 28 Permit No. COR-030000 (e erII. CTIANGES IN THIS GENERAL PERMIT (CONI,) K Terms and Conditiow, SWMP Requirements 1.SWMP Review/Changes: This section now requires that when changes are made to site condttians, the SWMP must be revised immediately, exceptfor some BMP description changes which conditionally may occur within 72 hours. This requirement is included to both ensure that the SWvIP be kept accurate and up-to-date, and to ctarifi that stormwater management at a site typically should be proactive instead of responsive, and be integrated into site rnanagement to eilsure it is calibrated with those changes. The section was also clarified to state that only changes in site conditions that do not require new or modified BMPs do not need to be addressed in the SWMP. See Pan 1.D.5(c) of the permit. SWMP Certilication: The previous permit was unclear on a requirement that the coPy of SWMP that remains at thefacility had to be signed in accordance with permit signatory requirements. This requirement has been deleted. The signatory requirement of Part I.F.I only applies to the SWMP if it is to be submitted to the Division or to EPA. See Pan I.F.I of the permit. Terms and Conditions. Post-Storm Insoections The previous permit required post-storrn inspections, but did not specify the timing of inspections. This section now requires that post-storm event iwpections generalllt be conducted within 24 hours of the event. An altematiye timeline has been allowed, onlvfor sites where there are no consttaction activities ocarring following a storm event. For this conditian, post-storrn event inspections shall instead be conducted prior to commencing construction actiyities, but no later than 72 hours following the storm event, and the delay noted in the inspection report. Any exceptionfrom the minimum inspection schedule is temporary, and does not eliminate the requirement to perform routine maintmance due to the effects of a storm event, including maintaining vehicle traclcing controls and removing sedimentfrom impertious areas. In mony cases, maintenance needs will require a morefrequent inspection schedule than the minimum inspections required in the petmit, to ensure that BMPs continue to operate as needed to comply with the permit. See Part 1.D.6(a) of the permit. Terms and Conditions. Inspections 1. The Winter Conditions Inspection Exclusion section has been modified to include documentation requirements for this exclusion. See Part 1.D.6(a) of the permit. The Inspectian Scope has been modified to include the requirement to inspect waste storage areas during inspections conducted in abcordance with the permit- See Part 1.D.6(b) of the permit- 2 - The requirements for sites to quatify for reduced inspection frequencies for completed sites have been slightty modified (see Part ID.6(a)(2) of the permit,). The requirement now is that only construction activities that disrurb the ground sudace must be completed. Constnrction activities that can be conducted without disturbance of the ground surface; for example, interior building construction, and some oil well activities, would not prohibit a sitefrom otherwbe qualifyingfor the reduced inspection frequenqt. In addition, the requirement for the site to be prepared for final stabilization has been slightly modified to allow for sites that have not yet been seeded to qualify, as long as the site has otherwise been preparedforfnat stabilization, including completion of appropriate soil preparation, amendments and stabilization pracrice. This will allowfor sites with seasonal seeding liminfions or where additional seed application ntay be needed in thefuture to still qualifu- 2. L.

The Inspection Report/Records section (Port I.D-6(b)(2)) was added to claifi reguirementsfor inspection reports generated during an inspection conducted in accordance with Part ID.6 of the permit- Inspection reports must be signed by the inspectar, or the individual verifuing the corrective action indicated in the inspection report, on behalf of the permittee. Iwpection repor8 are not typically required to be submitted to the Divisian, and therefore, are not required to be signed and certifiedfor accuraq, in accordance with Part 1.F.1 of the permit. Howeven any inspection reports that are submined b the Division mustfollow the signatory requiranents contained in that section. il. Terms and Conditions. Maintenance, Repair. and Reolacement of Control Practices .These sections have been added to clartfi requirementsfor maintaining the BMPs identified in the SWMP andfor addressing ineffective orfailed BMPs. BMP maintenance and site assessment to determine the overall adequacy of stormwater quality mctnagement at the site must occur proactively, in order to ensure adequate control of pollutant sources at the site- In most cases, if BMPs are already not operating efectively, or havefailed, the issue must be addressed immediately, to prevent discharge of polluunts. See Parts 1.D.7 and 1.D.8 of the permit. O. Total Maximum Dailv Load (TMDL) . A section on TMDLs has been added. This section gives a general outline of the additianal requiremen8 that may be imposed by the Division if the facility dbchatges to a waterbody for which a stormwater-related TMDL is in place. See Section WII.C of the rationale and Part I-D.l I of the permit. P Additional Delinitions , Part I.E of the permit has been modified to remove the definition of ntnoffcoeficient, as it is no longer a . permit requirement. The definition for state waters has also been deleted, but can be found in Regulation 61 . O. Chanpes in Discharqe The section on the types of discharge orfacility changes that necessitate Division notifrcation has been clarfied- See Part II.A.1 of the permit. .R. Non-ComplianceNotification The section on notification to the Division regarding instances of non-compliance has been amended to clarifu which types of noncompliance require notiJication- See Pan II.A.3 of the permit. S. Short Term Certifications The previous permit allowed small short-term constntction activities to be authorizedfor a predetermined periodfrom 3 to 12 months, and then automatically expire (an inactivation request did not need to be submined). The issuance of these certifications has led to signiJicant confusion and incidents of noncompliance resulting from permittees unintentionally letting their cenifications apire prior to Jinal stabilization, as well as issues regarding billing. Therefore, the provisionsfor short-term certifications have beeru deleted. T. Bvoass The Division has revised the Bypass conditions in Pan II.A.5 of the permit to be consistent with the requirements of Regulation 61.8(3)(il. The revised language addresses under what rare occurrences BMPs may be bypassed at a site. u. PARTII iH;l:Z",il o3oooo BACKGROUND As required under the Clean Water Act amendments of 1987, the Environmental Protection Agency @PA) has established aframeworkfor regulating municipal and industrial stormwater discharges. Thb framework is under the National Poilutant i*chaile eh^iratton-System Q',IPDES) program (Note: The Colorado program is referred to as the Colorado Dicharge Permit System, or CDPS, instead of NPDES-) The Water Quality Control Division (,,the Division,,) has stormiater regulitions (SCCR 1002-61) in place. These regulations require speclrtc types o1idost Al facitities that discharge stormwater associated with industrial activity (industrial stormwater), to obtain a CDpS permitfor such dischirge- The regulations specificalty include constntction-activities that disturb one acre iJ hna i, *ore as indusiial facilities. Constntction activities that are Part of a larger cornmon plan of developmint which disturb one acre ar rnore over a period of time are also included- A. General Permits The Division has determined that the use of general permits is the appropriate procedurefor handling rnost of the thousands of industrial stormwater applications within the state- B. Permit Requirements This permit does not impose numeic efiluent limits or require submbsion of efiluent monitoing data in the permit application or ii the permtt itsi-y. fhe permt insiead imposes practice-based effluent limitations for stormwater discharges throigh the requiremeit to develop and implement a Stormwater Management Plan (SWM1). The narritive permit requiretnents include prohibitions against discharges of non-stormwater (e.g., process water). See Pan LD.3 of the permit' The permit conditions for the SWMP include the requirementfor dischargers to select, implement and maintain Best Management Practices (BMPI) at a permitted constntction site that adequately minimize pollutants in the discharges to ctssure compliance with the terms and conditions of the permit. Part I'D'2 of the permit includes basi desfgn standari for BMPs implemented at the site. Facilities must select, install, implement, and maintain appropriate BMis, followtng good engineering, hydrologic and pollution control pictices. BMps implemii"alt the site must be adequately designed to control all potential pollutant sources associated with construction activity to prevent pollution or degradation of State waters' Pollution is defined in CDpS regulations (SCCR tOOi-Oi as mai-made or man-induced, or natural alteration of the physical, chemical, biological, and radiologica'l integrity olw2ter. Utilizing industry-accepted standards for BMp selection thar are ipproprtate for thiconditions and polluwnt sources present will typically be adequate ta neet these citeia, since construction BMPs u'e intended to prevent the discharge of all but minimal amounts of sediment or other pollutants that would not result in acrual pollution of State waters, as defi.ned abore.

This condition is the basis for all CDPS Discharge permits' and addresses the need to ewure that waters i|th" Snt" maintain adequate water quality, in accordance with water quality sandards, to continue to meet their designated ttses. It is believed that, in most cases, BMps can be adequate to meet appltcable water quality standards. If water quality impacts are noted, or the Division othiwise daermfnii that additionai permit requirements are necessar!, they are typically imposed as follows: I ) at the renewal of this general permit or through a general permit specific to an industrial sector (if the issue is sector-iased); 2l through directionfrotn the Division based on the implementation oja TMDL (if the bsue is watershed-bised); or j) if the issue is site-specific, through a revision to the ce:rtification jom the Divbion ba.sed on an inspection or SWW review, or through an individual permit- .#\ fLr,\- t1 PARTU Iffi;lTJ,i,l-o3oooo BACKGROUND (cont.) Some construction sites may be required to comply with a Qualifying Local Program in place of meeting several of the specific requirements in this permit. Sites covered by a Qualifying Local Program moy not be requirei to suimit- an application for coverage or a notice of inactivation and may not be required to pay the Division's annual fee. See Section WI of the rationale- C. Violations/Penalties Dischargers of stormwater associated with industrial activity, as defined in the CDPS regulations (SCCR I00Z-6i, thai do not obtain coverage under this or other Colorado general permits, or under an individual CDPS permit regulating industrial stormwater, wilt be in violation of the Federal Clean Water Act and the Colorado Water Quality Contol Act, 25-8-101. Forfacilities covered under a CDPS permit, failure to comply with any CO\S perrntt requirement cowtitutes a violation. As of the time of pertnit issuance, civil p"rilitesTo, violationsi|th",l."t o, CDPS permit requirements may be up to $10,000 per da1t, and ciminal pollution of state waters is punishable byfines of up to $25,000 per day. STORMWATER DISC HARGES ASSOCUTED WTH CONSTRUCTION ACTIWTY The stormwater regulations (CDPS regulations (5CCR 1002-61)), require that stormwater discharges associated with certain industrial activities be covered under the permit program. Constntction activity that disturbs one acre or more duing the life of the project is specifically included in the listed industrial activities. This permit is intended to coyer most stormwater discharges from constructionfacilities required by State regulation to obtain a permit. A. ConstructionActivitv Constntction activity includes ground surface disturbing activities inctuding, but not limited to, clearing, grading excavation, demolitian, insallation of new or improved haul and access roads, staging areas, stoclqiling offill materials, and dedicated borrow/fill areas. Constntction does not include routine maintenance to maintain oiginal line and grade, hydraulic capacit-t', or ariginal purpose of thefacility. Qhe maintenance exclusion is intendedfor projects such as road resurfacing, and where there will be less than one acre of additionat ground disrurbed. Improvements or upgrades to aistingfacilities or roads, where at least one acre is disnrbed, would not qualify as "routine maintenance-") DeJinitions of additional terms can befound in Part I-E of the permit. Stormwater discharges from all constraction activity require permit coverage, exceptfor operations that result in the disturbance of less than one acre of total land area and which are not Part of a larger common plan of development or sale. A "larger common plan of development or sale" is a contiguous area where -multiple sepaiate and distinct construction activities may be aking place at dffirent times on dffirent schedules. B. Tvoes of Discharses/Activities Covered 1. Stormwater: This permit is intended to cover most new or existing discharges composed entirely of stormwaterfrom construction activities that are required by State regtlation to obtain a permit. This includes stormwater discharges associated with areas that are dedicated to producing earthen materials, such as soils, sand, and gravel, for use at a single construction site. These areas may be located at the constntction site or at some other location. Thb pertnit does not authorize the discharge of mine water or process waterfrom bortpw areas.

Coveraqe under a Oualifuing Local Prosram - For Small Construction Sites Onlv For small construction sites (disurbing less than 5 acres) covered under a Qualifying Local Program (see Section WI, above), only certain permit requirements apply, as outlined below. The local program must have beenformally designated by the Division to qualify. Most municipalities have some type of local program and may requ*e permits andfees. However, simply having a program in place does not -necessarily mean that it is a quatifiing program end that a State Permit is not required. The local municipality is responsible for notifying operators and/or owners that they are covered by a Qualifying Local Program. As of May 31, 2007, the only approved Qualifying Local Programs within the state arefor Golden, Durango and Lakewood. An updated list of municipalities with Qualifying Local Programs, including contact information, is available on the Division's website at: Itm://v,'vnt.cdolte.state.co.ttsit+'o/PermitsUnit,/stormv,atericonstntction. html.

(t\.r ({f\9.. r\ PART II Permit - Page 35 PermitNo. COR-030000 WIL TERMS AND CONDITIONS OF PERMIT (cont.) Master SWMP Often, a large construction project will involve multiple smaller constnrction sites that are within a common plan of development, or mukiple well pads under construction within an oil and gas well field. Pollutant sources and the types of BMPs used can be relatively consistent in such cases. A permittee could significantly streamline the SWMP development process through the use of a master SWMP. SWMP information must be developed and maintainedfor all construction activities that qceed one acre (or gre part of a cornmon plan of development exceeding one acre) conducted within the permixed area. By developing a single master plan, the permittee can eliminate the need n develop repetitive information in separate plans. Such a plan could include two sections, one containing a reference section with information applicable to all sites (e.g., installation details and maintenance requirements for many standard BWs, such as siltfence and erosion blankets), and the second containing all ofthe infonnation spectfrc to each site (e.g., site BMP map, drainage plans, details for BMPs requiring site spectfrc design, such as retention ponds). As new activities begin, information required in the SWMP is added to the plan, and as areas becomefinally sabilized, the related information b removed. Records of information related to areas that have been Jinally stabilized thqt ore removed from the active plan must be maintained for a period of at least three years from the date that the associated site is finally stabilized. C. Total Manimum Dailv Load tMDL) If the designated use of a stream or water bodlt has been impaired by the presence of a pollutant(s), development of a Total Maxiruum Deily Load QMDL) malt be required. A TMDL is an estimate of allowable looding in the waterbody for the pollutont in question. Types of discharges that are or have the . potential to be a significant source of the pollutant are also identified. If a TMDL has been approvedfor any waterbody into which the permittee discharges, and stormwater discharges associated with construction activity have been assigned a pollumnt-specific Wasteload Allocation (WLtl) under the TMDL, the Division will either: l. Notifu the permittee of the TMDL, and arnend the permittee's certification to add specific BMPs and/or other requirernents, as appropriate; or 2. Ensure that the TMDL is being implemented properly through alternative local requirements, such as by a municipal stormwater permit. (The only carrent example of this is the Cherw Creek Resen oir Control Regulation (72.0), which mandates that municipalities within the basin require specific BMPs for construction sites.) See Pan 1.D.11 of the permitforfurther information. D- Monitorins Sampling and testing of stormwaterfor specific parameters is not required on a routine basis under this permit. However, the Division reserves the nght to require sampling and testing on a case-by-case basis, in the event that there is reason to suspect that compliance with the SWMP is a problem, or to measure the effectiveness of the BMPs in removing pollutants in the efiluent. See Pan I.D.l(e) of the permit. E. Facilitvlnsnections Construction sites typically must inspect their stormwater management controls at least every 14 days and within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion. At sites or portions ofsites where ground-disnrbing construction has been completed but avegetative cover has not been established, these inspections tnust occur at least once per month.

Reduction of pad size is catea interim reclamation, andgenerally includes recontouring ofthe site. spreadirg oftoproil on recontoured areas and reseedingthose areas' and installation of BMPs that will be piesent during the Iife of the wells (see Section7'0 for details on reclamation procedures). Interim reclamation generally isn,t initiated at a wellpad site untii the site has reached the Production well Deveropment phase (see Section 4.2.1.2). Sediment discharge' produced fluids and small amounts of equipment operationar lube or fuel orcorrosion inhibitors or other chemicals are potential pollutants of concern during this stage ofconstruction' As indicated in the Production well Development phase (Section 4.2.1.2), thepresence of tanks for storage of produced fluids will require implementation of an Spcc plan toprevent and control possible leaks from those tanks. In addition, secondary containment will beprovided for any tanks storing chemicals that are utilized during the life of the wells. If the site undergoes interim reclamation, temporary BMps may need to be instalred duringearthwork' as needed' to eliminate sediment, chemical or other non-stormwater related dischargesduring regrading activities' Temporary BMPs utilized may include perimerer contror andtemporary slope stabilization BMPs. The inspection schedule will change from monthly to every14 days' including post-precipitation inspections (see Section g.2), until the reclamation earthworkis completed and a, Iong-term sabirization BMps are in prace. Long-term slope stabilization BMPs that may be utilized during this stage include revegetation,mulching' tacking' blanketing. armoring and terracing.

Used materials will either be discharged to the reserve pit orcaptured in tanks for closed-loop drilling processes. petroleum products are used for theduration of the drilling process to fuel or lubricate equipment and include: fuel, gear oil,hydraulic oil' brake fluid, and grease' Materials to be used to cement casing placed in the wellmay also be stored and prepared on location or may be transported to the site. Structural BMPs specific to the drilling phase may be installed ro control discharges associatedwith specific pieces of equipment or iacilities for storage of materials on the location. suchBMPs may include non-construction related stormwater diversions; secondary containmentstructures around chemical storage areas and equipment, such as berms, collection ditches and.lorwater bars; and water bars at the pad entrance. with the presence of chemicals onsite, someactive BMPs may be temporarily disabled during the driliing phase to prevent unmonitored swdischarges from occurring. Appropriate replacement BMps will be installed, if needed. certain non-structural BMPs may be utilized during this phase to assist in managing stormwatercompliance such as Iimiting traffic, conducting training and inspections. providing equipment andprocedures to prevent spills of sewage or other materials, and ensuring that good materialmanagement practices are being implemented. Procedures wiil also be imf,lemented for promptcontainment and remediation of any spiils that may occur during the driiling phase. As equipment is demobilized at the completion of this phase, the well pad and surrounding areaswill be carefully inspected to identify any spills or reaks that may have occurred so that those areascan be remediated prior to initiation of thawell completion phase. All structural BMps will alsobe inspected and maintained during the demobilization of "quip-"nt to insure that any damage tothese BMPs resulting from demobilization is promptly repaired. Well Completion The Well Completion phase includes hydraulic fracturing (fracing), cementing, and other processes that stimulate the well and prepare it for production. The basic activities that are conducted during this phase include: . Mobilization of equipment required for well completion . Storage of do*nhole chemicals. fuels and lubricants . Installation of potable water tanks and sewage-handling equipment (e'g', portable toilets or sewage vaults) or continued maintenance of such equipment installed during the drilling phase . Fracing and other well-stimulation processes . Drill out of any plugs placed during well completion with a work-over rig . Flowback of the welito remove frac water, sand and other impurities . Demobilization of equipment when this phase has been completed Several temporary facilities/structures will be placed on site during this phase. These will include: frac trucks. storage and office trailers. generators, and frac tanks' During completions, certain chemicals may be used to stimulate the formation for the extraction of natural gas. Unused water and chemicais will be stored on the pad. Used water will be stored in the reserve pit or cleaned up and recycled in other operations. Sediment discharge. unused and used chemicals and frac water are potential pollutants of concern during this phase of construction' Structural BMps specific to the well completion phase may be installed to control discharges associated with specific pieces of equipment or facilities for storage of materials on the location. Such BMPs may include non-construction related stormwater diversions; secondary containment structures around chemical storage areas, tanks and equipment, such as berms. collection ditches and/or water bars; and water bars at the pad entrance. With the presence of chemicals onsite, some active BMPs may be temporarily disabled during the drilling phase to prevent unmonitored SW discharges from occurring. Appropriate replacement BMPs will be installed, if needed' Certain non-structurai BMPs may be utilized during this phase to assist in managing stormwater compliance such as limiting traffic, conducting training and inspections, providing for equipment and procedures to prevent spills of sewage or other materials" and ensuring that good material *urug.-"rt practices are being implemented. Procedures will also be implemented for prompt containment and remediation of any spills that may occur during the completion phase. As equipment is demobilized atthe completion of this phase, the well pad and surrounding areas will be carefully inspected to identify any spills or leaks that may have occurred so that those areas can be remediated prior to initiation of the production phase. All structural BMPs will also be inspected and maintained during the demobilization of equipment to insure rhat any damage to these BMPs resulting from demobilization is promptly repaired' i0 Production The Production phase includes the installation of long-term facilities such as permanent well heads, storage tanks, gas processing equipment, flow measurement equipment, and any associated flow lines needed to produce natural gas from the formation. An actively producing gas well produpes fluid phase along with gas phase products. Storage tanks may be placed on site during this phase to hold any produced water and/or fluid phase hydrocarbons (condensate). Sediment discharge, produced fluids, and small amounts of equipment operational lube or fuel or corrosion inhibitors or other chemicals are potential pollutants of concern during this phase of construction' The installation of tanks for storage of produced water and/or condensate triggers the requirement to include the site under the Spill Prevention Control and Counterrneasure (SPCC) plan. Any stored chemical, including produced fluids. are required to have appropriate secondary containment. Structural BMPs specific to the Production phase may be installed to control discharges associated with specific pieces of equipment or facilities for storage of materials on the location. Such BMPs may include non-construction related stormwater diversions; secondary containment structures around tanks and equipment, such as earthen berms or steel containment. BMps that may have been temporarily disabled during the drilling or well completion phases to prevent unmonitored SW discharges from occurring may be re-enabled during this phase as there is less risk of chemical discharge. Certain non-structural BMPs may be utilized during this phase to assist in managing stormwater compliance such as limiting traffic, conducting training and inspections, providing for equipment and procedures to prevent spills of sewage or other materials, and ensuring that good material management practices are being implemented. Procedures will also be implemented for prompt containment and remediation of any spills that may occur during the production phase. 4.2.2 Access Roads and Pipeline Right-of-Way Construction Access roads and pipeline right-of-ways (ROWs) offer unique challenges for construction and stormwater management due to their linear nature and ability to intersect large drainage areas. For these main reasons, stormwater for these two construction activities'is generally manageddifferently than for well and facility pads. This section offers more detail on how stormwater is managed for access roads and pipeline ROWs. 4.2.2.1 Access Road Construction The development of natural gas wells also requires the construction of access roads. Access road construction is generally accomplished by using traditional cut and fill techniques but may also require blasting and other techniques. Size and maintenance requirements for each road are based on road location, traffic level andlor landowner's stipulations. Extra care and planning is taken to identify and protect sensitive areas, such as stream or drainage crossings, prior to construction. 11 BMps will be impremented before and during construction of roads and will be maintained throughout the lifetime of the road o*ntii ,tuuiriration reach* u point that they are not needed' Stnrctural BMPs used during road construction and maintenance will include, at a minimum, cutandfillslopestabilizationandrevegetation: diversionofnon-projectwaterthrougharmoredculvertsorotherappropriateBMPs; road surface stabilization techniques' including utilizing crushed rock' road base' gravel' paving and/or comPaction; grading, including insloping' outsloping and crowning; and collection and management of onsite storrnwater through ditches, drainage dips' waterbars' dams, traps, and perimeter controls' BMps will be selected and placed with consideration given to the unique aspects of each access :"::,._ methods for re-establishing vegeration on cut and.fi, slopes usually include hydroseeding' drill seeding o, u.*l"ast seeding. s.r""rion of seed mixes is coordinated yith the iandowners and/or serected b;;" soil and climate conditions and desired vegetative properties' Site specific se"d mirel"u, u. found on trre-sJt" maps rocated in the sw* database (see Appendix c for SwM access and navigation instructions).

Reveeetation (RV) Revegetation involves planting seed to estabrish a vegetative cover on disturbed areas.Revegetation reduces erosion and sedimentation by stabirizing disturbed areas in a manner that iseconomical and adaptable to site conditions. It urro ..aur* .::otr vorumes by increasing waterpercolation into the soil' binds soil with roots, and protects soir from *iro ".orion. The permanentil11,IJ;JtT;#ff4 r,*ffi:_lrrii:i_ru::::,, wi,, be se,ec,ed by,he Riprap (R) 21 Hydromulch [FIM) Riprap is a layer of large, hard, angular stones used to protect soil from erosion in areas of concentrated runoff. Riprap can also be used on slopes that are unstable because of seepage problems. Roadside Ditches (RSD) Roadside ditches are channels constructed parallel to roads. The ditches convey concentrated runoffof surface water from roads and surrounding areas to a stabilized outlet. Slope Drain (SD) A slope drain is a conduit extending the length of a disturbed slope and serving as a temporary outlet for a diversion. Slope drains convey runoff without causing erosion on or at the bonom of the slope. Stabilized Constructi on Entrance (SCE) A stabilized consffuction entrance is temporary stabilization of on-site roadway by placement of gravel roadbase. Stabi I ized Constructi on Roadwav/Surface ( S CR) Stabilized construction roadways incorporate gravel surfacing and proper grading on access roads, but are also incorporated on pad surfaces. Gravel surfacing may be used to cover soil in areas of high traffic, such as, roads. facility areas, and areas near the well heads. Gravel surfacing forms a layer that protects and minimizes soil erosion and vehicle soil tracking. Grading involves reshaping the ground surface to pianned grades as determined by an engineering survey, evaluation, and layout. Grading provides more suitable topography for well pads, pipelines, facilities and access roads and helps to control surface runoff, soil erosion. and sedimentation during and after construction in these areas. Grading also includes road crowning and sloping to properly route runoff off the access roads. Surface Rou ghening (SR) Soil surface roughening is a temporary erosion control practice often used in conjunction with grading. Soil roughening involves increasing the relief of a bare soil surface with horizontal grooves (corrugating) or tracks (tracking) using construction equipment. Slopes that are not fine graded and that are left in a roughened condition can reduce erosion, trap sediment, and prepare ground surfaces for seeding. Terracine (T) Slope construction with benches or terraces spaced at regular intervals perpendicular to the slope which intercept and collect sheet flow and direct it to a stable outfall point. Turnouts (TO) 22 Turnouts are used to effectively remove run-off water from the roadside ditch into well- stabilized areas before it reaches a waterway. Water Bar (WTi) A water bar is a ridge of compacted soil, loose rock, or gravel constructed across disturbed right- of-ways and similar sloping areas. Wind Erosion Control (WEC) Consists of applying water or other dust palliatives as necessary to prevent or alleviate dust nuisance generated by construction activities. Covering small stockpiles or areas is an alternative to applying water or other dust palliatives. Existing vegetation cover and topsoil are removed only where necessary for the operation of equipment and construction of the pad. Trees and large shrubs that are not cleared from the pad area will be protected from damage during construction by avoiding them with equipment. For example, the biade of a bulldozer will be in a raised position except for designated areas. Trees will be cut or trimmed only to facilitate clearing, grading, and safe installation of a pad. Trees outside the area of disturbance will not be cut, but may have overhanging limbs trimmed, if necessary. 6.2.1.2 Sediment Reduction and Control The control and reduction of sediment contained in stormwater runoff will be accomplished by the use of sediment containment systems. Sediment containment systems are hydraulic controls that allow the detention of suspended particles via gravity, filtering or entrapment. Sediment controls that will be used to mitigate and control sediments generated from the erosive transporl forces of stormwater during and after construction of a pad will include but will not be limited to the following: Berms (B) A berm is a ridge of compacted soil located at the top or base of a sloping disturbed area to contain or divert surface runoff. The purpose of a berm is to control runoff velocity, divert onsite surface runoff to a sediment trapping or filtration device and/or divert clean water away from disturbed areas. Brush Baniers (BB) A temporary sediment barrier constructed at the perimeter of a disturbed area from the residue materials available from clearing and grubbing the site, and generally covered with filter fabric. Culvert Protection (CP) Culvert protection may be required at the inlet to the culvert (upstream side) and /or the outlet to the cuivert (downstream side). lnlet protection will reduce the velocity of stormwater flows and thereby erosion and help protect the inlet structure. Outlet protection will also reduce the 23 velocity of storrnwater flows and thereby prevent scouring at structure, and minimize the potential for erosion downstream' the culvert outlet, protect the outlet Filter berms are efficient form of bales Placed on a level contour to filters sediment laden runoff from structures that are designed to slow' are exPected to reduce' Filter Berm (FB) A nt,"t berm is temPorarY ridge placed along a level contour to sediment control' Sediment traps are intended to detained runoff to slowlY drain' other point of discharge from a and/or constructing an earthen runoff.

Most disturbed areas not designated as working areas wiil be seeded and mulched during interimor final reclamation to stabilize the soils. Table I contains approved seed mixtures and distributionrates that are generally used in the Piceance Basin; ho*"u"i, Nobre is not bound to using theseseed mixtures and application rates only. Seed mixtures and application rates are based uponseveral factors including facility and well pad surrounding vegetation, desired vegetative H 27 properties, soil types, elevation, surface relief and landowner specifications' Typical Pure Live Seed (PLS) application rates are recommended to be doubled if seeding is performed by hydroseed or broadcasting. well sites and areas which are identified as Bureau of Land Management (BLM) sites require specific seed mix approval as directed by the Glenwood Springs, co' Energy office' BLM reclamation requirements and policy .erisio's are updated periodically and can be reviewed in Appendix D. For areas of disturbance that are on private land' the land owner may specify a specific seed mix. please refer to Table 1 and the site maps in the SWIM database for site-specific seed mixes (see Appendix c for swIM access and navigation instructions)' Disturbed areas reasonably needed for production operations that do not require restoration and revegetation in accordance with coGCC Rule 1003.e will not be immediately revegetated, but will be stabilize d as stabilized unpaved surfaces. The term "stabilized unpaved surfaces" includes dirt road surfaces and the portions of the well pad surfaces that cannot be revegetated due to operational necessity, but does not include slopes, ditches' and other areas where revegetation is necessary. Stabilized unpaved surfaces will be prepared in such a way as to minimize erosion' including constructing surfaces with crushed rtck, road base' gravel' and/or compaction' and utilizing insloping, ouisloping and crowning grading techniques to prevent rilling' 7.2 Post-Construction Structural Measures permanent water bars, culverts and/or other permanent.structural measures may be installed on ,t..p ,top., and at wetland and stream crossing boundaries' After restoration and reclamation work is complete, required repairs to vegetation and erosion and sediment control BMPs will be completed, as required' 7.3 FinallY Stabilized According to stormwater regurations, ,.finaily stabirized means that air ground surface disturbing activities at the site have been completed ani all disturbed areas have been either built on, paved. or a uniform vegetative cover has been established with an individual plant and a density of at least 70 percent of pre-disturbance levels, and the vegetation cover is capable of providing erosion control equivalent to pre-existing conditions' or equivalent permanent' physical erosion reduction methods have been employed'" A special condition exists for oil and gas pad sites- regarding stabilized unpaved surfaces' AccordingtotheCDPHEstormwaterFactSheetdatedJuly200T: Areasdevelopedasstabilizedunpavedsurfacesasneededforoperationofthe.facility after interi* ,rrlo*rtion also furhfi' ": "finallv stabilized"' The term "stabilized unpaved surfaces" includes dirtiiad'surfacis and rhe portions of the well pad surfaces that cannot be revegelated du.e to operLtional necess-ity, but 4o:t 4 include slopes' ditches ond other areas where revegelation is necessary' stabilized unpaved surfaces 28 must be prepared in such a woy as to minimize erosion, such as preventing rill erosion onpad surfaces or roads.

Regular cleaning ofdiversion ditches and other BMPs to keep them free of debris and sediment ,iitt be practiced.Spillways and culvert systems will also be routinely cleaned and inspected. These maintenanceprocedures will help to insure that the stormwater does not leave disturbed areas via unintendedchannels. The following preventive maintenance procedures will be implemented to reduce or eliminatepotential stormwater contamination sources that may exist on a .it", ' Storage containers, fuel tanks. and equipment used during construction activities shouldbe visually inspected routinely for obvious leaks. These inspections should be conductedby site and contractor personnel as they perform their routine duties; ' Drums will be properly labeled so an enclosed substance can be quickly identified.oSHA-approved labeling and sign systems wiil be followed for all secondary containers; ' Erosion damage to the earthen berms, outfalls, silt barriers. collection channel,containment ponds, and any erosion and sediment control will be repaired as soon aspractical; 29 Areas of stained soil will be inspected in order to identify the sources of the staining' contaminated soil will be removed and properly disposed; Energy dissipating material, such as riprap' cobbles or gravel will be placed' or existing materials will be utilized at the stormwater outfalls to prevent erosion damage' Barrow ditches should be free from vegetation and debris which may cause impounding of stormwater; and Stormwater management structures wiil be cleared of debris and repaired when necessary; and surface runoff controls such as curbing, culverts, and ditches will be used to control runoff. 8.1.1 Good HousekeePine In accordance with BMps that provide procedures to eliminate contamination, and direct, divert, and contain stormwater, Noble has implemented a number of housekeeping practices' These practices will help prevent soil sedimerrt, i.urf,, and toxic or hazardous substances from entering navigable waters. Housekeeping practices include regular cleaning, organization and maintenance of pad equipment and erosion and sediment control struc-tures throughout the project' Areas where chemicals are stored and used at the project are stored in weather-proof buildings or containers and/or contain secondary containment io prevent stormwater contact or runoff' These areas include producing pads that typically consist of wellheads, separator units, dehydration units' and 3OO-barrel capacity aboveground stock tanks' The following items will be addressed in order to maintain a clean and orderly pad during the J"r"l op-"nt,-production, and abandonment phases of work : . InsPect Pad areas routinelY; . Correct deficiencies noted during inspectionsl . Clean and maintain stormwater management structures and components; . Routine trash collection and proper disposal; . Familiarize employees and contractors with spill clean-up equipment and storage locations; and . Familiarize employees and contractors with good housekeeping procedures and pad pollution prevention procedures' 8.1.2 Material Storase The following good housekeeping practices will be followed at the material storage areas: 30 ' Storage containers will be stored away from direct traffic to prevent accidents. They willalso have proper labels; rrv'vrlr ever\ ' Dumpsters and trash receptacles will be enclosed in order to prevent the dissemination ofrefuse; . Storage areas will be kept free of refuse; ' chemical substances used at pads will be properly labeled and will have proper spillcontainment; and ' chemical substance containers will be clearly labeled with an MSDS kept on file. 8.1.3 Waste Removal All waste from materials imported to the construction site will be removed for disposal/recyclingto an appropriate licensed disposavrecycling facility, including sanitary sewage facilities(typically portable)' No.wastes of imported materials shall be buried, dumped, or purposelydischarged to waters of the state. There are no other pollutant sources from areas other thanconstruction areas. 8.2 Inspections To meet the requirements of CDPHE Stormwater General permit No. coR-0 3g5zT,inspectionand maintenance of erosion and sediment controls must occur during the construction project.Continued inspection and maintenance is required for specific structures after construction iscompleted' As of August 2008, Noble utilizes the sWIM database to report and record theresults of stormwater inspections, BMP installations, and repairs/maintenance. A complete listof active inspection locations, site maps and site specific stormwater BMps are provided in theSWIM database' Please refer to Appendix C for more information on how to access andnavigate the SWIM database. The inspection program includes the following: 1' A trained and qualified person familiar with the swMP and stormwater controls conductsfacility inspections and enters inspection results into the SryIM darabase. 2. Inspections cover these areas: . Evidence ofsurface erosion for disturbed areas;. Material and chemical storage areas;. Best Management practices (BMps);. Surface water diversions and downgradient areas;. New access roads and ditches; and. Locations where vehicles enter or exit the site. 3l 3. Inspections occur at least once every 14 calendar days and after a precipitation events or snowmelt events that cause surface erosion. 4. Permanently stabilized areas are inspected at least once per month. 5. A physical log of inspections has been completed for all inspections prior to August 2008 and is located in Noble's Rifle, Colorado. office for a minimum of three years. Inspections occurring after August 2008 are recorded and maintained electronically in the SWIM database. Access to the SWIM database and directions for its navigation are reviewed in Appendix C. 6. Inspections are not required for disturbed areas when snow cover exists over the entire site for an extended period as lbng as melting conditions do not exist. 7. Water quality is visually assessed for all receiving streams and discharge areas during each inspection, if present. 8. Disturbed areas and material storage areas that are exposed to precipitation are inspected for evidence ofpollutants entering nearby drainages. 9. Check dams, wattles, and other BMPs are inspected for evidence of deterioration. under- cutting, and build up of sediment. Sediment needs to be removed when it has built up one-third to one-half the height of the BMP structure. 10. Roads used for vehicle access are inspected for evidence of off-site sediment transport. I 1. The SWMP is modified, as necessary, whenever there is a change in design, construction or operation that changes the potential for pollutant discharge to waters of the state. 12. An eiectronic inspection report summarizing the scope of the inspection, the name of the person conducting the inspection, date of inspection, and observations relating to the implementation is prepared and stored electronically utilizing the SWIM database. Access to the SWIM database and directions for its navigation are reviewed in Appendix C. 13. Actions taken to correct deficiencies associated rvith an inspection are recorded in the SWIM database, including the date the deficienc,v was corrected, the company responsible for the correction, and correction comments. Access to the SWIM database and directions for its navigation are reviewed in Appendix C. 14. If no deficiencies are found during the inspection. or when all deficiencies relating to an inspection have been corrected, the report contains a certification statement and an eiectronic signature that the site is in compliance ll,ith the SWMP and the General Permit. 3/. Personnel performing facility inspections for access roads, pipeline right-of-ways, well pads or other operational facilities will record site conditions in the SWIM database. When deficiencies are discovered, work orders are generated and reviewgd by Noble to direct designated subcontractors to perform maintenance or replacement of existing BMPs, or installation of additional BMPs. Maintenance will include prompt adjustments and repairs to erosion and sediment control structures that are found to be performing inadequately or deteriorating. Signs of rill or gully surface erosion shall be repaired as quickly as practical. New BMP installations will be in accordance with this SWMP and the BMP manual Best Management Practices for Stormwater Managemerzl, considered part of this SWMP. 8.2.1 14-dav Inspection/Active Construction Stase During the construction stage, the inspection frequency forNoble sites is at least every 14 days and after any precipitation or snowmelt event that causes surface erosion. The pad perimeter, disturbed areas, and any stored materials that are exposed to precipitation will be inspected for evidence of, or the potential for pollutants to enter the drainage system. Erosion and sediment control systems that are identified on the electronic site-specific SWMP Inspection Report (in the SWIM database) will be inspected to ensure that they are in good condition and operating properly (see Appendix C for SWIM access and navigation instructions). 8.2.2 Monthly Inspection/Completed Staee For sites or portions of sites that meet the following criteria, but final stabilization has not been achieved due to a vegetative cover that has not become established, Noble will make a thorough inspection of their stormwater management system at least once every month, and post-storm event inspections are not required. This reduced inspection schedule is only allowed if: i) all construction activities that will result in surface ground disturbance are completed (Note: only construction activities that result in a disturbance of the ground surface must be completed. Construction activities that can be conducted without disturbance of the ground surface, such as certain well completion activities, would not prohibit a site fiom otherwise); ii) all activities required for final stabilization, in accordance with the SWMP, have been completed, with the exception of the application of seed that has not occurred due to seasonal conditions or the necessity for additional seed application to augment previous efforts; and iii) the SWMP has been amended to indicate those areas that will be inspected in accordance with the reduced schedule allowed for in this paragraph. 8.2.3 Monthlv InspectionAnterim Stabilization Staee For sites that meet the conditions of Section 8.2.2 and the slopes of the site have been seeded for revegetation, the site is considered to be in the interim stabilization stage and is also eligible for the same reduced inspection schedule as for sites in the completed stage. 33 8.2.4 Final Stabilization Staee When a pad site has reached final stabilization, it will be removed from the CDPHE stormwater permit by submitting an Amendment Notice Form to the CDPHE. Regulation of NEI's stormwater management at the site will then fall under Colorado Oil and Gas Conservation Commission (COGCC) rules and stormwater at the location will be managed with NEI's S tormw ate r Mana ge ment P I an for P o s t C o ns truc t io n Ac t iv i t i e s (SWMP -PCA). 8.2.5 Winter Conditions Inspections will not be required at pads, access roads and pipeline right-of-ways where snow cover exists over the entire site for an extended period, as long as melting conditions and construction activities do not exist at the site. Sites are generally assumed in compliance if BMPs are not visible due to snow cover, unless previous repairs or maintenance issues are still outstanding. Snow covered sites without open repairs are recorded as ''ln Compliance" on the associated stormwater inspection reports maintained in the SWIM database (see Appendix C for SWIM access and navigation instructions). The beginning snow cover dates, dates of construction activity and dates when melting conditions began are recorded for each site on the inspection reports where the snow cover inspection exclusion is utilized. 8.2.6 Precinitation Event Inspections Active site inspections of sites in the Construction stage u,ill be conducted within 24 hours after a precipitation or snowmelt event that causes surface erosion. If no construction activities will occur at a pad site following a storm event, post-storrn event inspections will be conducted prior to re-commencing construction activities, but no later than 72 hours following the storm event. Surface erosion generally occurs when precipitation or snowmelt results in surface water flow. If the precipitation infiltrates, then no inspection is required. In order to determine if surface erosion or surface water flow resulted lrom a precipitation or snowmelt event, pumpers and other field personnel are consulted immediately following a precipitation event as to the field conditions in each of the areas (Rulison, South Grand Valley and Rulison). If field personnel observe new erosion or BMPs that need maintenance following a precipitation event, post- precipitation stormwater inspections are initiated immediately. 9.0 EMPLOYEE TRAINING Noble will inform and train employees who are involved with SWMP activities, including stormwater inspectors, stormwater administrator(s), BMP contractors, construction foreman and BMP designers. Training will be conducted on an as-needed basis and will cover information and procedures contained in the SWMP as described below. A Training Log can be found in Appendix E recording the training dates and attendees. The following topics are presented and discussed during SWMP training: . Introduction to CDPS Stormwater Permit: . Stormwaterregulations; . Purpose of stormwater permit: . Requirements of stormwater permit: 34 Components of the SWMP; Identification of potential pollutant sources; BMPs and proper construction; Preventative maintenance; Good housekeeping; Inspections and maintenance; and Record keeping (SWIM database purpose and navigation). 1().O RECORD KEEPING The following record keeping procedures are implemented in order to provide accurate and complete documentation of events associated with the stormwater management program' Rouiine inspections will include the l4-day, monthly, and post precipitation event inspections' Stormwater related inspection reports, site maps, and site narratives are maintained electronically in the SWIM database after August 2008 (see Appendix C for SWIM access and navigation instructions). Prior to this date, inspection reports and site maps are maintained in hard copy form. All stormwater reiated records will maintained by Noble for a minimum of three years. Site-specific records will be kept a minimum of three years from final stabilization. 11.0 SWMP REVIEW/CHANGES Noble will amend the SWMP whenever there is a significant change in design, construction, operation, or maintenance which has a significant effect on the potential for the discharge of pollrt rtr to water of the state, or if the SWMP proves to be ineffective in achieving the general tbjectives of controlling pollutants in stormwater discharges associated with pad activities' The SWMP is considered a "living document". 35 - Garfield CounQ BUILDING & PLANNING DEPARTMENT MEMORANDUM FROM: DATE: SUBJECT: Board of County Commissioners Glenn Hartmann, Senior Planner January 14,2013 Noble Energy lnc. - Rulison Compressor Station Extension Request - Olsson & Associates The Building and Planning Department has received an extension request for the Noble Energy lnc., Rulison Compressor Station located on property owned by Joan L.
