ENCANA. July 1, 2008 Garfield County Building & Planning Department 108 8th Street, Suite 201 Glenwood Springs, CO 81601 RE: Lake Fox Water Quality Data. Dear Sir or Madam: 2717 County Road 215 Suite 100 Parachute, CO 81635 P: (970)285-2739 Please find the attached data summary table and laboratory analysis report for water samples collected from the Lake Fox Water Storage Pond on June 6, 2008. The on site Monitoring Well was dry on the date the lake was sampled. The Hubble domestic well, which is located down gradient of Lake Fox was sampled on this date. The data summary table also lists several reference standards for comparison with the analytical results. These standards are provided for relative comparison only, as the water is not intended to comply with any of the referenced regulatory standards. The water will be contained on site or used solely for natural gas exploration and production activities. As such, the water will not come in contact with the general public or with environmental receptors such as soil, ground water, or surface water. Please do not hesitate to contact our Parachute office should you have any questions or comments. Sincerely, EnCana Oil & Gas (USA) 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. TIC - Tentatively Identified Compound: Compounds detected in samples that are not target compounds, internal standards, system monitoring compounds, or surrogates.

The results prompted a few questions: y sent to our 1) Middle Fork Water Storage Pond: Why are the Dissolved Solid readings (550 mg/I) higher than the Regulatory Standards (500 mg/I) found ithe up gradient monitoring well and is there any way to reduce those levels to below Regulatory Standards? 2) Hunter Mesa Water Treatment Plant: Why are the Manganese readings (0.09 mg/l) higher than the Regulatory Standards (0.05 mg/l) found in the fresh water holding pond and is there any way to reduce those level to below Regulatory Standards? s to 3) Lake Fox Water Storage Pond; The sole purpose of the Board of County Commissioner's requirement for Encana to install a down gradient water monitoring well was to monitor any activity that might come from Lake Fox. We appreciate the results from the neighboring well; however. what does Encana propose to do to its monitoring well so that it functions ns as We look forward to hearing your response to these questions. l am discuss over the phone as well. happy to Very truly yours, Fred A.

Dear Sir or Madam: Please find the attached data summary table and laboratory analysis report for water sam collected from the Lake Fox Water Storage Pond on May 2, 2007. The o pees Well was dry on the date the lake was sampled. The Hubble domestic well, which is located down gradient of Lake Fox was sampled on this date. The data summary e also lists several reference standards for comparison with the analytical results. These standards are provided for relative comparison only, as the water is not intended to comply with any of the referenced regulatory standards. The water will be contained on site or used solely for naturalas the exploration and production activities. As such, the water will not come in contact withg general public or with environmental receptors such as soil, ground water, or surface water.Please do not hesitate to contact our Parachute office should you have any questions comments. or Sincerely, EnCana Oil & Gas (USA) 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 'Rt (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.

Comment 1: Attachment 1 provides a Piping and Instrumentation Diagram (P&ID) and an explanation of the engineering basis for this facility. Comment 2: Attachment 2 provides a copy of the general stormwater permit application filed with CDPHE for this project. It is anticipated that a copy of the stormwater permit will have been received from CDPHE prior to the March 17, 2008 hearing for this SUP and, if so, a copy of the permit will be provided at that time. If you have any questions or require additional information, please contact me at 970-263-7800. Sincerely, De mon soci a Geologist Enclosures — As Stated Cc: Amy Stoodt, Marathon Oil Company Project File EG07148 Cordilleran Compliance Services, 'Inc. Grand Junction, CO ■ Denver, CO Environmental Consulting Engineers and Scientists ATTACHMENT 1 Explanation of the Project: Marathon Oil Company (MOC) plans to install three (3) 600 HP pump units in the SE 1/4 Section 36 of Township 5 South Range 95 West for a freshwater pipeline system to deliver water to the top of the adjacent mesa. The system will include a pump station, connect to an existing 8" pipeline owned by Berry Petroleum (4.8 miles), and tie into a Marathon pipeline (2.3 miles) on top to deliver freshwater to two freshwater holding ponds with 125,000 BBLS total working volume. The valley design will be ANSI 900# and the mesa pipe will be ANSI 600#. Total elevation gain is from 2,400' (5,700' to 8,100'). This system will provide freshwater for both Marathon Oil Company and Berry Petroleum. The function of this system is to deliver freshwater (non -potable) to the top of the mesa for drilling, completion, and construction purposes. In the drilling process, water is used to remove cuttings from the wellbore, as well as to provide backpressure on drilled formations to prevent blowouts. In well completion operations, water at high rates and pressures is used to break open hydrocarbon bearing rock (at depth) and transport sand into the fractures to enable wells to produce. These pumps will not be used for completions, simply to supply water to the operation. For construction, water is used for dust abatement as well as for soil compaction. Altogether, MOC and Berry cumulative anticipated water need is up to 20,000 barrels per day (BPD). Operation of this system will be dictated by water need. The pumps are sized to enable MOC to deliver the peak rate with two of the units with the 3rd unit serving as a hot spare. The 3rd unit also allows for make up capacity should pond volumes be depleted during some unforeseen circumstance. Reason for This Project: This system will significantly reduce truck traffic on the Garden Gulch road, which is MOC's main access to the mesa, At predicted peak volume of 20,000 BPD, this system will save approximately 150 round trips (600 man hours) on the road each day. Over the first phase of development this system has the potential to save over 243,000 round trips by water haulers (over 973,000 man hours) to the top of the mesa. Load Profile: The system will typically operate with two units at 60 Hz pumping at 11,700 BPD each for a total of 23,400 BPD. Each unit will draw approximately 390 HP. Changes to one unit or three units will be made as need dictates. Max flow would be 35,000 BPD (three units running) but would be likely < 25% of the time. Typical operation of two units is likely > 50% of the time, with a single unit being similar to 3 units at < 25%, 0 r 133 1 -0 c m v LTI 4. w \/ *1 m A f * Hr mt rat `r -, • �..i—i' - — :I ( 2 G 1� r x ' il 2 41 c 2 e.5 T 3 i biI • tau illc _ > „Ji z ,,(,, 0 500 BBL WATER TAI WITH HEAT ,_ A .z at 0 CD M .4 • CD ' Y cn z 500 BBL WATER TANK WITH HEATER ■ 0 cn ■ g _ IM 0 y ■ • CS 500 BBL WATER TANK WITH HEATER C i 144 O g Z CI CID x 0 0 4, . 500 BBL WATER TANK WITH HEATER v �"•a8 E O ►. 173 a H-r •CD CIDva 500 BBL WATER TANK WITH HEATER );•_ _ �CD.

This SWMP addresses construction activities associated with development of the Fresh Water Pump Station, owned and operated by Marathon Oil Company (Marathon). A copy of the associated storm water permit can be found in Appendix A. This SWMP was prepared to address storm water management practices at areas disturbed by construction activities associated with operation of the Fresh Water Pump Station. This SWMP is intended to be revised as necessary to address planned developments, new disturbances, and other changes needed to manage storm water and protect surface water quality. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the U.S. from any point source be regulated by NPDES permits. In November 1990 the EPA published final regulations that established application requirements for storm water associated with construction activity for soil disturbances of 5 acres or more be regulated as an industrial activity and covered by an NPDES permit. In December 1999 the EPA published final Phase II NPDES regulations that established application requirements for storm water associated with construction activity for soil disturbances to be regulated as an industrial activity and covered by an NPDES permit. These regulations became effective July I, 2002. On June 30, 2005, Colorado storm water regulations went into effect to require Colorado Discharge Permit System (CDPS) permits for storm water discharges from construction activities for small (1 to 5 acre disturbance) oil and gas activities. Federal permit coverage for these discharges was conditionally exempted from the Federal Clean Water Act by the 2005 Federal Energy Bill. On February 1, 2006, the CDPHE issued a letter clarifying that the CDPHE Water Quality Control Commission decided to maintain the existing requirements for storm water permitting for oil and gas construction sites of 1 to 5 acres. 1.2 Project Description The Fresh Water Pump Station will be located within the SE/4 of Section 36, Township 6 South, Range 96 West of the 6th P.M. in Garfield County, Colorado. The town of Parachute, Colorado is the nearest population center. The Fresh Water Pump Station will be located approximately 10 miles north-northwest of Parachute. The current local drilling and development plan includes pad construction, access road improvement/construction, Page 1 Fresh Water Pumping Station SWMP Marathon Oil Company and installation of associated facilities. The proposed Fresh Water Pump Station will provide fresh water to support these activities. 1.3 Project Owner and Operator Marathon Oil Company (Marathon) is the project operator, developer, and is actively conducting exploration and development of the natural gas resources. Their address is: Marathon Oil Company 743 Horizon Court, Suite 220 Grand Junction, Colorado 81506 Ph (970) 245-5233 The Marathon contact person for the project is Robert V. Coleman. Mr. Coleman can be contacted by phone at (970) 245-5233. Marathon will be in charge of all aspects of the property and this project. Contractor(s) will do the actual construction and drilling but all work will be supervised by Marathon and all decisions will be made by Marathon. Page 2 Fresh Water Pumping Station SWMP Marathon Oil Company 2.0 CONSTRUCTION SITE DESCRIPTION The following sections describe the site location and provide a description of the construction arca. Runoff characteristics of this area are also described. 2.1 Site Location and Construction Area Description The location for this proposed fresh water pumping station is on property owned by EnCana Oil and Gas (USA) Inc. and leased and operated by Marathon. The parcel comprises 958 total acres of land. The arca of activity does not come into contact with any adjacent properties. The nearest adjacent property owner from this site is 1/10 of a mile away. The closest municipality is the town of Parachute, 10 miles southeast. The site is about 9.5 miles up County Road 215, and A mile up a private road in an area that is currently used for oil and gas exploration and production activities. The proposed fresh water pump station will be constructed to support Marathon's operations in the area. The total area of disturbance for the site will not exceed 4.0 acres. The disturbed area includes the pump station site pad and a 50 -foot wide strip for a fresh water pipeline from the Solvay Pump House located about 900' to the northeast to the northeast corner of the site pad. Reclamation and final stabilization will be conducted as described in Sections 4 and 7. Regional precipitation amounts vary from 11.59 inches per year in Rifle, Colorado to 14.8 inches in Colbran, Colorado (Western Regional Climate Center). Due to regional climate conditions, lack of surface water or shallow ground water, construction dewatering is not expected for the Fresh Water Pumping Station site. 2.2 Schedule of Construction Activities Material removal operations in the quarry will begin when all necessary permits and plans are in place. For new disturbances, Best Management Practices (BMPs) will be installed prior to, during, and immediately following construction activities as practicable with consideration given to safety, access, and ground conditions (e.g. frozen ground) at the time of construction. When activities in the area have ceased and there is no longer a need for the fresh water pump station, it will be abandoned. Upon abandonment all surface equipment will be removed and the remaining area will be reclaimed utilizing the following measures: contouring disturbed soils to conform to the surrounding terrain, replacing the stockpiled top soil, seeding of disturbed soil areas in order to reestablish cover vegetation, and construction of erosion and sediment control structures as needed. Once stabilization is achieved, defined as uniform vegetative cover established with a density of at Least 70 percent of pre -disturbance levels, the pump station's storm water permit will be inactivated. However, if petroleum hydrocarbons or other chemicals impact storm water as a result of industrial activities onsite, the site will maintain permit coverage and ensure SPCC plan BMPs are maintained. Page 3 Fresh Water Pumping Station SWMP Marathon Oil Company. 2.3 Runoff Characteristics Runoff characteristics are based on site topography, soil type, and soil/vegetative cover. The major soil type in this permitted area is Rock outcrop-Torriorthents complex. The slopes range from 40% to 80%. Native vegetation land cover types include serviceberry, bitterbrush, mountainmahogany, big sagebrush and western wheatgrass. Soils are well drained, surface runoff is rapid and the erosion hazard is moderate. Storm water runoff receiving waters include Garden Gulch and Parachute Creek. The ultimate receiving water is the Colorado River. Page 4 Fresh Water Pumping Station SWMP Marathon OH Company 3.0 POTENTIAL POLLUTION SOURCES Potential pollution sources associated with construction sites include: Sediment resulting from erosion of soil stockpiles and other areas cleared of • vegetation; • Sediment discharges from vehicle tracking; Leakage of fuels and lubricants from equipment and spills from fueling and; • Trash and debris from clearing activities, construction materials, and workers The most common source of pollution from construction is sediment, which can be carried away from the work site with storm water runoff and impact the water quality of a receiving stream. Clearing, grading. and otherwise altering previously undisturbed land can increase the rate of soil erosion over pre -disturbance rates. Petroleum products can also be potential storm water pollutants. These products are used in construction activities to power or lubricate equipment and include: fuel, gear oil, hydraulic oil, brake fluid, and grease. Debris from laydown areas, residue from equipment cleaning and maintenance, and solid waste generated from land clearing operations and human activity (trees, brush, paper, trash, etc.) present other potential pollution sources within the construction site. Magnesium chloride solution or other chemical dust suppressants may be applied during the summer to unpaved roads to order to reduce fugitive dust generation. Magnesium chloride solution is used in the winter for roadway deicing and in the summer for dust suppression by county and state government entities. The solution is typically delivered to the site by contractors in DOT approved tanker trailers and generally is quickly applied to the road surface. Occasionally, depending on work site conditions, the tanker trailers may be staged along the road until ready for application (typically no longer than overnight). Spills or leaks from potential sources will be further described in the field -wide SPCC plan when development of the Piceance field -wide SPCC plan becomes required. The SPCC plan will be available in the field and will be located with the SWMP. Response to certain events may require specialized training due to health and safety concerns. Page 5 Fresh Water Pumping Station SWMP Marathon Oil Company 4.0 DESCRIPTION OF CONTROL MEASURES The following sections provide a description of BMPs, including physical structures employed to prevent soil erosion; work practices and managerial controls used to prevent storm water impacts; and fuels, chemicals, and materials handling practices. The use of a combination of physical BMPs, good work practices, and storing fuels, chemicals, and materials in covered and isolated areas will prevent storm water impacts. 4.1 Soil Erosion and Sediment Controls The objective of erosion and sediment controls is to minimize the release of sediments to storm water runoff. This can be accomplished through the use of structural and/or nonstructural controls. This section describes physical erosion and sediment controls to be used at active construction sites to minimize possible sediment impacts to storm water runoff. For BMP installation details refer to Appendix C and selection guidelines are listed in Figure 3. Berms A berm is a ridge of compacted soil located at the top or base of a sloping disturbed area to contain or divert surface runoff. Where used, soil berms shall be constructed of soil with sufficient fines to minimize flow through the berm. 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. Check Dams Check dams are small, temporary dams constructed across a diversion or roadside ditch. Check dams can be constructed using gravel, rock, gravel bags, geo-ridges, earth with erosion control blanketing, straw bales, or wattles and are used to slow the velocity of concentrated flow in a channel. As a secondary function, check dams can also be used to catch sediment from the channel itself or from the contributing drainage area as storm water runoff flows through or over the structure. Culverts Culverts are typically used to move ditch water under the road or to direct stream flow under the access road. Culverts are typically constructed out of concrete, steel, aluminum, or plastic pipe. Where used, culverts should have inlet and outlet protection features to minimize erosion such as placing a non -woven textile material under rip rap at each end of the culvert. Diversion Permanent diversion berms and structures control storm water runoff by using a channel and an earthen ridge to prevent sediment laden storm runoff from leaving the construction site or other disturbed arca to prevent flows from eroding slopes and to Page 6 Fresh Water Pumping Station SWMP Marathon Oil Company direct sediment laden flows to a trapping device. Diversions are most often constructed of earthen materials with vegetative cover and are best used with channel linings such as vegetation or matting. Diversions are typically used wherever the direction and velocity of runoff from up slope areas need to be controlled. A good example would be diverting upgradient surface runoff away from a construction site. Channels and berms must be designed to manage peak storm flow and must be stabilized to prevent erosion of the channels. Drainage Dip Drainage dips intercept and remove surface water from access roads, construction pads, and roadside ditches (before the combination of water volume and velocity begin to erode.) Drainage dips are constructed diagonally across the flow of the surface water and will pass slow traffic while dispersing surface water. Erosion Control Blanket Erosion control blankets and turf reinforcement mats (TRM) are porous fabrics that are manufactured by weaving or bonding fibers made from organic or synthetic materials. Erosion control blankets are installed on steep slopes, over berms, or in channels to prevent erosion until final vegetation is established. The erosion control blankets can also be used as separators or to aid in plant growth. Filter Berm A filter berm is temporary ridge made up of natural materials that already occur on the project site. Brush filter berms use small tree branches, root mats, grass, leaves, stone or other debris or material naturally available or left over from the site clearing and grubbing. Rock filter berms use site gravel, stone, or rock. Both types of filter berms are placed along a level contour to slow, filter, and divert flow and act as an efficient form of sediment control. Georidge® GeoRidget is a permeable ditch berm designed for erosion and sediment control. The use of GcoRidge® reduces flow velocities and provides a smoother water flow resulting in less erosional energy. and thus minimizing the problem of downstream sediment. Gravel Surfacing Gravel surfacing may be used to cover soil in areas of high traffic, including roads and facility areas. Gravel surfacing forms a layer that protects and minimizes soil erosion and vehicle soil tracking. Land Grading Grading involves reshaping the ground surface to planned grades as determined by an engineering survey, evaluation, and layout. Grading provides more suitable topography for facilities and access roads and helps to control surface runoff, soil erosion, and Page 7 Fresh Water Pumping Station SWMP Marathon Oil Company sedimentation during and after construction in these areas. Grading also includes road crowning and sloping to properly route runoff off the access roads. Level Spreader A Ievel spreader is a BMP used to prevent erosion and to improve infiltration by spreading concentrated storm water runoff evenly over the ground as shallow sheet flow instead of through channels. It usually involves a depression in the soil surface that disperses flow onto a flatter area across a slight slope and then releases the flow onto level vegetated areas. This reduces flow speed and increases infiltration and promotes evaporation. Mulching Mulching is a temporary erosion control practice in which materials such as grass, straw, hay, wood fibers or wood chips are placed on exposed or recently planted soil surfaces. Mulching stabilizes soils by minimizing rainfall impact and reducing storm water runoff velocity. When mulching is used in combination with seeding, surface soils retain moisture, promote seed germination and help insulate roots from extremes temperatures. Retaining Wall Retaining walls are structures that are used to stabilize and hold soil in place, gain space on roadways, or to keep soil contained within a site boundary. This BMP can be constructed with rock, boulders, and/or cement blocks. Revegetation Revegetation involves planting seed to establish a vegetative cover on disturbed areas. Revegetation reduces erosion and sedimentation by stabilizing disturbed areas in a manner that is economical and adaptable to site conditions. It also reduces runoff volumes by increasing water percolation into the soil, binds soil with roots, and protects soil from wind erosion. The permanent seed mix, rate, application method, and supplemental materials will be selected by the revegetation contractor or the BLM representative for Federal sites. Riprap Riprap is a permanent, erosion -resistant layer made of stones, rock, or boulders. It is intended to stabilize areas subject to erosion and protect against scour of the soil caused by concentrated, high velocity flows. Roadside Ditches and Turnouts Roadside ditches are channels constructed parallel to roads. The ditches convey concentrated runoff of surface water from roads and surrounding areas to a stabilized outlet. Turnouts are used to effectively remove run-off water from the roadside ditch into well -stabilized areas before it reaches a waterway. Page 8 Fresh Water Pumping Station SWMP Marathon Oil Company Sediment Trap Sediment traps are intended to intercept, trap, and retain sediment from runoff while allowing detained runoff to slowly drain, infiltrate, or both. They are usually installed in a drainage way or other point of discharge from a disturbed area. This BMP is formed by excavating below grade and/or constructing an earthen embankment with a protected spillway to slow the release of runoff. Silt Fence Silt fences are used as temporary perimeter control structure that is designed to slow, temporary impound, and filter sediment laden water. Installation techniques and maintenance is critical to proper performance. Slope Drain Slope drains are used with earth dikes and drainage ditches to intercept and direct surface flow away from slope areas to protect cut or fill slopes. A slope drain is applicable for any construction site where concentrated surface runoff can accumulate and must be conveyed down a slope in order to prevent erosion. The slope drain may be a rigid pipe such as corrugated metal, flexible conduit or a lined terrace drain with the inlet placed at the top of the slope and the outlet at the bottom of the slope. Inlets must be securely anchored and outlets must be stabilized with riprap. Stabilized Construction Entrance A stabilized construction entrance is a pad of gravel laid over filter cloth where construction traffic will be entering or leaving a construction site to or from a public right-of-way, street or highway. This is also referred to as vehicle tracking control. The purpose of a stabilized entrance to a site is to minimize the amount of traced mud and dust that leaves the site and tracked onto county roads or state highways. As a vehicle drives over the gravel, mud and sediment are removed from the vehicle's wheels and offsite transport of soil is reduced. This BMP reduces erosion, tire rutting and the filter fabric separates the gravel from the soil below by minimizing the migration gravel into subsurface soil from heavy vehicle loads. A stabilized construction entrance should be used at facility ingress and egress locations. Straw Bale Barrier A straw bale barrier is a series of entrenched and staked straw bales placed on a level contour to intercept sheet flows. The barrier reduces runoff velocity and filters sediment laden runoff from small drainage areas of disturbed soil, This BMP may also be used to protect against erosion in small shallow drainage channels. Straw Wattles Straw wattles or rolls are intended to capture and keep sediment on slopes or in small shallow drainage channels. Straw rolls can be used to temporarily stabilize slopes by Page 9 Fresh Water Pumping Station SWMP Marathon Oil Company reducing soil creep, sheet and rill erosion until permanent vegetation can be established. Straw rolls will last an average of one to two years. Surface Roughening Soil surface roughening is a temporary erosion control practice often used in conjunction with grading. Soil roughening involves increasing the relief of a bare soil surface with horizontal grooves (corrugating) or tracks (tracking) using construction equipment. Slopes that are not fine graded and that are left in a roughened condition can reduce erosion, trap sediment, and prepare ground surfaces for seeding. Terrac ing Terraces are made of either earthen embankments or ridge and channel systems that are properly spaced along a fill slope. Terraces are constructed with an adequate grade to promote drainage to a stabilized outlet. They reduce damage from erosion by collecting and redistributing surface runoff to stable outlets at slower speeds and by decreasing the distance of overland runoff flow. They also surpass smooth slopes in holding moisture and help to minimize sediment loading of surface runoff. Vegetative Buffer Vegetative buffers are areas of either natural or established vegetation that are maintained to protect the water quality of neighboring areas. Vegetative buffers reduce storm water runoff velocity, prevent soil erosion, promote infiltration and act as a filter to remove sediment. Water Bar A water bar is an earthen ridge, or ridge and channel, constructed diagonally across a slope road, trail, or disturbed area. Water bars are normally used for drainage and erosion protection of closed, blocked, or infrequently used roads to divert storm water runoff and minimize erosion. 4.2 Storm Water Management Controls Structural BMPs will be installed, inspected, and maintained as needed. This SWMP will be revised as necessary to address new disturbances, construction or operation. Depending on the type and location of new facilities there may be a need for inclusion of new and different BMPs. In general, new development should be planned with consideration for storm water quality (e.g. minimize disturbed area and maximize distance from surface water drainages, as practicable). Other developments on the property, primarily existing andlor improved roads, not currently or specifically addressed in the SWMP will be periodically checked for erosion and drainage problems. This is especially important for access roads located within 100 feet of surface drainages or creeks. If problems are noted, they should be reported to the Production Superintendent andlor SWMP administrator. Problem areas may be addressed Page 10 Fresh Water Pumping Station SWMP Marathon Oil Company through construction activities, but will likely need to be addressed through BMPs which will be added to the plan as needed. 4.3 Other Controls Waste Management and Disposal Construction and operational activities at the quarry will generate various other wastes during the course of construction. Other wastes may include the following: • Sagebrush, shrubs and trees from clearing operations; • Trash and debris from construction materials and workers; and ▪ Sanitary sewage. Each of these wastes will be managed so as to not contribute to storm water pollution. Construction trash and debris will be collected in containers and hauled off-site for disposal in suitable landfills. Sanitary waste will be containerized in portable toilets or other storage tanks with waste materials regularly pumped and transported off-site for disposal at approved facilities. Fuels and Materials Management Petroleum products which may be present at the construction site include: gasoline, diesel fuel, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline and diesel fuel will be stored in portable storage tanks with secondary containment. Lubricant, hydraulic, and miscellaneous oils and solvents will be stored in 55 -gallon or smaller containers. Pollutants from petroleum products used during construction activities adhere easily to soil particles and other surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to a proper disposal site. Proposed soil erosion and sediment control practices will aid in retention of spills or leaks. Use of secondary containment and drip pans will reduce the likelihood of spills or leaks contacting the ground. Proposed maintenance and safe storage practices will reduce the chance of petroleum products contaminating the road site. Oily wastes such as crankcase oil, cans, rags, and paper containing oils will be placed in proper receptacles and disposed of or recycled. An additional source of petroleum contamination is leaks from equipment and vehicles. Routine daily inspections will be conducted to identify leaks and initiate corrective actions, if needed. The following guidelines for storing and managing petroleum products will be used: • All product containers will be clearly labeled. • Drums will be kept off the ground within secondary containment and stored under cover if needed. • Fuel tanks will be stored within secondary containment. • Lids of drummed materials will be securely fastened. • Emergency spill response procedures will be available on-site. Persons trained in handling spills will be on call at all times. Page 11 Fresh Water Pumping Station SWMP Marathon Oil Company • Spill clean up and containment materials (absorbent, shovels, etc.) will be easily accessible. Spills will be immediately cleaned up and contaminated materials will be properly stored on site until they can be disposed of in accordance with applicable regulations. • Storage areas and containers will be regularly monitored for leaks and repaired or replaced as necessary. Contractors and subcontractors should be reminded about proper storage, handling and transferring of petroleum products or other hazardous materials during safety meetings. Spills or releases of any size that impact or threaten to impact any waters of the state, residence or occupied structure, livestock or public byway, shall be verbally reported to the COGCC as soon as practical after discovery (COGCC Rule 906). If the spill may reach waters of the state (which includes surface water, ground water and dry gullies or storm sewers leading to surface water), it must also be reported immediately to the Colorado Department of Public Health and Environment (CDPHE) at 1-877-518-5608. Spills or releases of more than 25 gallons of refined petroleum crude oil products such as gasoline, diesel fuel, oil, or derivatives of mineral, animal or vegetable oil shall be reported to the state of Colorado Division of Oil and Public Safety at (303) 318-8547 within 24 hours. A hazardous substance release in any amount which enters or threatens to enter waters of the state shall be reported to Colorado Department of Public Health & Environment (CDPHE). Other Chemicals Products Management Additional materials will be used and stored on site for use in construction. These materials will be stored appropriately and managed to minimize spills and leaks. Storage areas will be regularly inspected and any minor spills or leaks will be cleaned up immediately. Materials Management The construction contractor will maintain a laydown or staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will be inspected on a regular basis for spills, leaks, and potential of materials commingling with storm water runoff. 4.4 Construction Site Housekeeping Housekeeping will consist of neat and orderly storage of materials and containerized fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at off-site, suitable facilities. If spills occur, prompt cleanup is required to minimize any co -mingling of waste materials with storm water runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans will be used during routine fueling and maintenance to contain spills or leaks as needed. Page 12 Fresh Water Pumping Station SWMP Marathon Oil Company Any waste product from maintenance will be containerized and transported off site for disposal or recycling. There will be no major equipment overhauls conducted on site. Equipment will be transported off site for major overhauls. Cleanup of trash and discarded materials will be conducted on an as -needed basis. Cleanup will consist of patrolling the road way, access areas, and other work areas to pickup trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of appropriately. Page 13 Fresh Water Pumping Station SW MP Marathon Oil Company INSPECTION AND MAINTENANCE PROCEDURES To meet requirements of Storm Water General Permit No. COR-xxxxxx, inspection and maintenance of erosion and sediment controls must occur during the construction project. Continued inspection and maintenance is required for specific structures after construction is completed. A complete list of active inspection locations, site diagrams and site specific storm water BMPs are provided in the inspection report book kept with the SWMP. The inspection program will include the following: 1. A trained and qualified person familiar with the SWMP and storm water controls will conduct facility inspections and complete the Storm Water Field Inspection Report form in Appendix D. A trained and qualified person will have completed Storm Water Pollution Prevention training and includes signing the training session form in Appendix D. 2. Inspections will cover these areas: • Evidence of surface erosion for disturbed areas; • Material and chemical storage areas; • Straw bales, wattles, riprap areas, culverts and sediment traps; ▪ Surface water diversions and downgradient areas; • New access roads and ditches; and • Locations where vehicles enter or exit the site. 3. Inspections will occur at least once every 14 calendar days and after a O.5 -inch precipitation event or snowmelt events that cause surface erosion. 4. Permanently stabilized areas will be inspected at least once per month. 5. A log of inspections will be completed and maintained in Marathon's Grand Junction, Colorado office for a minimum of three years. 6. Inspections are not required for disturbed areas when snow cover exists over the entire site for an extended period as long as melting conditions do not exist. 7. Water quality will be visually assessed for all receiving streams and discharge areas during each inspection if present. 8. Disturbed areas and material storage areas that arc exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. 9. Check dams, wattles, and other BMPs will be inspected for evidence of deterioration, under -cutting, and build up of sediment. Sediment will be removed when it has built up one-third to one-half the height of the hay bales or wattles. Page 14 Fresh Water Pumping Station SWMP Marathon Oil Company 10. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. 11. The SWMP will be modified as necessary whenever there is a change in design, construction or operation that changes the potential for pollutant discharge to waters of the state. 12. An 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 will be prepared. An inspection report is provided in Appendix D. 13. Actions taken to modify storm water control measures will be recorded and maintained with the SWMP. 14. If no deficiencies are found during the inspection, the report contains a certification statement that the site is in compliance with the SWMP and the General Permit. Personnel perfonning facility inspections will record site conditions on the Storm Water Field Inspection Report form in Appendix D. Immediately when deficiencies are discovered, the Marathon Storm Water Administrator will be contacted and will direct designated subcontractors to perform BMP maintenance or replacement. Maintenance will include prompt adjustments and repairs to erosion and sediment control structures that are found to be performing inadequately or deteriorating. Signs of rill or gully surface erosion shall be immediately repaired. The Marathon Storm Water Administrator has the authority and will direct subcontractors to install new and or additional storm water control BMPs as needed. Page 15 Fresh Water Pumping Station SWMP Marathon Oil Company • 6.0 NON -STORM WATER DISCHARGES Non -storm water discharges are not expected from the construction projects. Possible exceptions include fire prevention/suppression or dust control activities. Page 16 Fresh Water Pumping Station SWMF Marathon Gil Company 7.0 FINAL STABILIZATION Areas which have been disturbed are considered to be stabilized when a uniform vegetative cover with a density of 70 percent of the pre -disturbance levels has been established or when an equivalent permanent, physical erosion reduction method is in-place. The disturbed areas will be seeded and mulched for final stabilization. Table 1 contains the seed mixture for the Fresh Water Pumping Station. Typical Pure Live Seed (PLS) application rates are recommended to be doubled if seeding is performed by hydroseed or broadcasting. Areas not used for facilities, access roads, materials storage yards, or other work areas will be stabilized with vegetation. Areas that are stabilized with vegetation will be considered to have achieved final stabilization when a uniform stand of vegetation with a density of at least 70 percent of the pre -disturbance has been established. Sprayed -on mulches and other slope stabilization materials may be used in combination with seeding techniques in select areas to promote and establish surface vegetation cover. Other areas which may include facilities, access roads, materials storage yards, and other work areas will be stabilized with the use of permanent, physical erosion reduction methods which include, but are not limited to: I. Surface hardening — covering of the soil surface with hardened products such as concrete or asphalt pavement. 2. Surface covering — covering of the surface soil with structure that inhibits contact of precipitation with the soil surface which is generally considered to be placement of a structure (building or tank) over the soil surface. 3. Gravel surfacing — gravel surfacing will be applied in areas such as access roads, materials storage yards, and other work surfaces. Some gravel may be lost due to erosion from intense precipitation events or due to vehicle traffic. Gravel surfaces will be periodically inspected to determine the need for gravel replacement. Gravel surfaces will be replaced or repaired (through grading) when inspection reveals that the gravel surface is no longer effectively covering the soil surface. Page 17 Fresh Water Pumping Station SWMP Marathon Oil Company 8.0 CONSISTENCY WITH OTHER PLANS This SWMP has been written and revised without the preparation of a separate SPCC plan specific to construction activities. In addition, the final condition and operational activities associated with the Fresh Water Pumping Station are not anticipated to require an SPCC plan that complies with §112.7 of the Oil Pollution Prevention Regulation (40 CFR §112) issued under section 311 of the Federal Water Pollution Control Act. 9.0 ADDITIONAL REQUIREMENTS FOR FACILITIES SUBJECT TO SARA TITLE III, SECTION 313 REQUIREMENTS The Fresh Water Pumping Station is not subject to SARA Title III, Section 313 requirements because there have been no releases of reportable quantities of hazardous materials to land or water from this facility.

PROXIMITY TO DRAINAGES Less than 100 feet Maximum control of ninon and runoff including ditches, berms, retention ponds, and check dams. No reliance on vegetative filters or other naturall occurring sediment controls. In general, disturbed areas which are closer to drainages will indicate the need for use of more BMPs, more structural BMPs, and less reliance on non-structural BMPs (such as c • ctative filters). 100to200 feet Moderate control of runon and runoff. Greater than 200 feet Less control of runon and runoff and more reliance on vegetative filters and other naturally occurring sediment controls DISTURBANCE OF DRAINAGES A primary goal of facility siting should be avoidance of drainages. If avoidance is not possible then mitigation should be conducted and permitting may be required. lithe drainage is not jurisdictional (regulated by the Army Corps of Engineers, ACE) then mitigation should be conducted but an ACE permit will not be required). If the drainage is jurisdictional then both a permit and mitigation will be required. If the disturbance is due to construction of an access road or pipeline, then a nationwide drainage crossing permit is likely to issued by the ACE within 1 to 2 months. The permit will have requirements on the drainage crossing intended to protect Waters of the U.S. If the disturbance is due to construction of a well pad or other facility site then serious consideration should be given to relocating the planned site. The ACE will require an Individual Permit which will take approximately 12 months to acquire. The Individual Permit will require archeological surveys, Threatened and Endangered (T&E) Species Surveys, and solicitation of comments from the public.

Refer to the diagram for steps 1-4 Step 1: A section of ECB shall be placed across the flowline direction of the channel prior to the Installation of the GeoRldga . The ECB section must span the entire width of the channel, while the width of the blanket must be at least one roll width or no less than 1.22m (4 ft.). Step 2: The upstream edge of the ECB must be secured In a 100mm (4") trench. Secure the blanket In the trench using 150mm orb inch minimum staples placed at 500mm (1.67 ft.) Intervals along the edge. Backfill and re -compact the soil In the upstream edge trench. Step 3: Secure the downstream edge of the blanket with 150mm or 6 inch minimum staples placed at 300mm (1 ft.) Intervals along the edge. with S4: Place the GeoRidge anchor 0Inch spial spikes. depends on soli condition and density. Minimum recommendation Is 3 anchors on the upstream side and 2 anchors on the downstream side. The anchors will prevent water from going around or under the G eoRldg e . (See figure 3.) NOTE: if multiple GeoRldge" panels are required to span a channel, ensure that the anchor holes line-up when you overlap each panel. (See figure 2.) SPACING: When net the gradient plays a key role In the distance between panels as follows GRADIENT SPACING 1% 23.0 m 2% 11.5 m 3"/e = 7.7 m 4% 5.8 m 0 4.6 m 6% 3.8 m 7% 3.3 m 89'0 2.9 m 9°/n 2.6 m 101/4 2 3 m nilex.COm 1-800-667-4811 NILEX Spacing is based on calculating the height of GeoRldgem divided by the gradient. Example: On a 2° gradient... 0.230 m (height of GeoRldge®t 0.02 Gradient = 11.5 m spacing.
