Storm Water Management Plan (SWMP) is written to comply with the Colorado Department of Public Health and Environment’s (CDPHE) General Permit No. COR- 030000 issued on May 31, 2007 and has been administratively continued effective of July 1, 2012, and related U.S. Environmental Protection Agency (USEPA) National Pollutant Discharge Elimination System (NPDES) storm water regulations. This larger common plan of development SWMP addresses construction activities associated with development of natural gas resources in the Battlement Mesa in Garfield County, Colorado. The Battlement Mesa SWMP is intended to be periodically updated as needed to address planned developments, new disturbances, and other changes needed to manage storm water and protect surface water quality. This SWMP will be updated in accordance with Parts I.D.5.c, d of the permit. This SWMP is in two parts: (1) the field-wide SWMP for Ursa activities within the Battlement Mesa project area; and (2) additional, dynamic, information (including inspection forms) for well pads, compressor stations, and roads. The field-wide SWMP includes a general area description, area boundary map, descriptions of Best Management Practices (BMPs), description of materials handling and spill prevention, inspection, maintenance procedures, and definition of final stabilization. Site-specific tables within this field-wide SWMP Appendices address individual ground-disturbing activities. The site-specific information found in Table 3 contains information such as facility location, construction limits, BMP locations and detailed current site conditions. Additional information on Ursa’s specifics of administrative operations is provided in the appendices. This SWMP will need to be updated/revised during the life of the project. Updates will include: 1. Revision of existing BMPs as needed to address erosion and sediment control. 2. Deletion of BMPs and reduction in monitoring frequency for individual facility locations where interim and long-term stabilization have been successfully established. 3. Regulation updates, Table and Appendix revisions. This SWMP will have a separate revision log sheet; this log sheet will have dates that the SWMP was modified as applicable, refer to Table 2. This SWMP is written to contain general storm water management practices, as well as site specific information related to specific construction activities occurring in the Battlement Mesa field area. Site specific information found in Table 1 includes phased BMP implementation, areas of disturbance, schedule of construction activities, final stabilization measures, current BMPs, and potential pollution sources. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the United States from any point source be regulated by NPDES permits. In November 1990, the USEPA published final regulations that established application requirements for storm water associated with construction activity for soil disturbances of 2 May 2013 5 acres or more be regulated as an industrial activity and covered by an NPDES permit. In December 1999, the USEPA 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 1, 2002. Storm water construction permits are required for oil and gas activities that disturb 1 or more acres during the life of the project, or are part of a larger common plan of development. CDPHE considers a common plan of oil and gas development to mean development of several well pads and/or related infrastructure in a contiguous area either during the same time period or under a consistent plan for long-term development. 1.2 Project Description and Background Within the Battlement Mesa project area, Ursa Operating Company, LLC (Ursa) is charged with construction, operation, and maintenance of access roads, well pads, and gas gathering pipelines and facilities. Ursa is responsible for implementing storm water management as it pertains to their respective operations within the Battlement Mesa project area. This SWMP is developed, maintained, and implemented to suit the needs of each construction activity within the Battlement Mesa project area. The Battlement Mesa natural gas wells and associated infrastructure will be located within Township 7 South, Range 95 West, of the 6th P.M. Construction activities will include clearing/maintenance of drilling pads, clearing/maintenance of natural gas facilities (compressor stations), construction/maintenance of access roads, and the eventual construction of natural gas flow and gathering pipelines. The area of disturbance including the natural gas well pads, the access roads and gathering system pipeline will be greater than one acre. Currently there are actively producing wells and natural gas facilities within the Battlement Mesa project area. Refer to Table 1 for information regarding existing facilities, proposed facilities, and facilities under construction. New disturbances will occur as additional access roads and well pads are constructed and/or maintained. 1.3 Project Owner and Operator The Project owner/operator: Ursa Operating Company, LLC 1050 17th Street, Suite 2400 Denver, CO 80265 Contact for the project is: • Robert W. Bleil, Regulatory & Environmental Manager/ SWMP Administrator Main: 970.625.9922 E-mail: rbleil@ursaresources.com Ursa will be in charge of all aspects of this project. Contractor(s) will do the actual construction and grading, but all work will be supervised by Ursa or a representative(s), and all decisions will be made by Ursa, or a representative(s). 3 May 2013 2.0 CONSTRUCTION SITE LOCATION DESCRIPTION 2.1 Site Location The Battlement Mesa natural gas wells and associated infrastructure will be located within Township 7 South, Range 95 West, of the 6th P.M. Once the natural gas wells are completed and brought into production it will be necessary to construct flow lines, gathering system pipelines and tank batteries to handle liquid storage, and construct access roads to the individual well sites and pipelines access points. The Battlement Mesa natural gas wells will be constructed using conventional cut and fill earthmoving techniques. Typically, the working pad surface will have dimensions of approximately 350’ x 250’. There will be a 50’ buffer area around the pad surface to implement storm water BMPs. Specific pad dimensions may vary depending on the planned drill rig, number of wells to be drilled from each pad, and local conditions. After all well pads have been constructed and all production facilities have been installed, the well pad will be graded to reduce cut and fill slopes and to minimize the overall size of the pad. The well pad will be revegetated after grading activities have been completed. This “interim reclamation” phase will exist until 70% stabilization (including revegetation, compacted road surfaces, etc.) has been reached, after which “final stabilization” will be declared. “Final stabilization” will require the 70% stabilization and the removal of any temporary BMPs. The well pad will remain in the “final stabilization” phase of the long-term production configuration for as much as 30 years or more (typically, until the well’s production declines to sub-economic levels). After a well has been plugged and abandoned and surface facilities removed, the well pad will be graded to restore approximate pre-disturbance contours and will be revegetated. In areas that are disturbed by well pad construction, topsoil will be stripped and stockpiled near the site. Topsoil stockpiles will be seeded as soon as practicable to preserve the topsoil resource. Soil materials will be managed so that erosion and sediment transport are minimized. Site Maps Refer to Appendix A for maps showing locations of well pads, access roads, pipelines and their associated storm water BMPs. Maps will be generated for each applicable well pad showing construction site boundaries, ground disturbance areas, cut and fill areas, all storage areas, all structural and non-structural BMPs, and all potential pollution sources. 2.2 Schedule of Construction Activities Construction schedules will vary. Minor road maintenance will occur on an “as needed” basis. Refer to Table 1 for information regarding site specific construction and maintenance activities for well pads and access roads. Once an approved drilling permit application has been received from the Colorado Oil & Gas Conservation Commission (COGCC), clearing and grading activities will be performed at the well pad sites. The clearing and grading will be performed during 4 May 2013 daylight hours to prepare the site prior to drilling. Temporary storm water BMPs will be implemented prior to well pad construction. Once stabilization is achieved, defined as construction activities being complete and all disturbed areas have been either built on, paved, or a uniform vegetative cover established with a density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed a well pad may be removed from this SWMP. However, if petroleum hydrocarbons or other chemicals impact storm water as a result of industrial activities onsite, the impacted storm water will be addressed by following the Ursa spill prevention control and countermeasures (SPCC) plan. 2.3 Runoff Characteristics Runoff characteristics are based on site topography, soil type, and soil/vegetative cover.

Vegetative cover varies from 40% to 100% depending on site specificity. 7 May 2013 3.0 POTENTIAL POLLUTION SOURCES Potential pollution sources associated with construction sites and natural gas development include: • Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; • Leakage of fuels and lubricants from equipment and spills from fueling; • Trash and debris from clearing activities, construction materials, and workers; • Sanitary sewage associated with portable toilets; • Well completion fluids; • Drill cuttings and drilling fluids; • Produced water; and • Condensate. The most common source of pollution from construction activities is sediment, which can be carried away from the work site with storm water runoff, and ultimately 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 lay-down 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. For site specific potential pollution sources, refer to Table 1. Maps of each well pad will be generated showing the locations of all potential pollution sources. No concrete washout activities are expected. Vehicle tracking pads may be required for well pad development within the Battlement Mesa. All BMPs implemented throughout the project are intended to mitigate for the release of sediment and all other potential pollution sources described above, and listed in Table 1. Ursa Operating Company spill prevention and response policies must be followed and include the following: • Notification procedures to be used in the event of a material release or accident. At a minimum, the production supervisor should be notified. Depending on the nature of the spill and the material involved, Ursa Environmental staff, the CDPHE, downstream water users, or other agencies may also need to be notified. The WQCD toll-free 24-hour environmental emergency spill reporting line is (877)518-5608. • Provisions for absorbents are to be made available for use in fuel areas. 8 May 2013 4.0 DESCRIPTION OF SOIL CONTROL MEASURES The objective of erosion sediment controls is to minimize the release of sediments and any other potential pollutants by storm water runoff. This can be accomplished through the use of structural and/or nonstructural controls. This section describes erosion and sediment controls to be used during the ROW construction to minimize possible pollutant impacts to storm water runoff. Refer to Appendix D for implementation details of soil control measures. Refer to Appendix A for locations of soil control measures. 4.1 Structural Practices for Erosion and Sediment Control Structural practices implemented to provide erosion and sediment control can include temporary and permanent BMPs. Temporary structural BMPs include, but are not limited to, straw bale barriers/check dams, temporary water bars and straw fiber rolls/wattles. When applicable, temporary BMPs will be implemented during construction and interim reclamation phases. All temporary BMPs will be removed and disposed of upon final stabilization. Permanent structural BMPs include, but are not limited to; earthen berms, drainage dips, bar ditches, diversion ditches, sediment basins, culvert inlet/outlet protection, and rock check dams. 4.1.1 Straw Bale and Rock Check Dams Straw bale and rock check dams will be installed in areas of concentrated flow. The purpose of a check dam is to reduce the velocity of water enough to allow sediment to settle, while allowing the clean water to continue migrating. Some sediment will accumulate behind the check dam. Sediment should be removed from behind the check dams when it has accumulated to one-half of the original height of the dam and properly disposed of. Check dams will be inspected for erosion along the edges of the check dams and repaired as required immediately. 4.1.2 Straw Wattles/Straw Rolls Straw rolls/wattles are intended to capture and keep sediment on a disturbed slope. Straw rolls are useful to temporarily stabilize slopes by reducing soil creep and sheet and rill erosion until permanent vegetation can be established. Straw rolls will last an average of one (1) to two (2) years. The slope needs to be prepared before the rolls are placed. Small trenches are created across the slope on the horizontal contour. The trench should be deep enough to accommodate half the thickness of the roll. The trenches need to be 10 to 25 feet apart. The rolls need to be installed perpendicular to water movement, parallel to the slope contour. The rolls need to fit snugly against the soil. No gaps should be between the soil and roll. There should only be one (1) to two (2) inches of stake exposed above the roll. The stakes should be installed every four (4) feet. 4.1.3 Diversion Berm/Channel Diversion ditches can be a temporary or permanent structural BMP installed to direct runoff or run-on storm water away from construction activity. Ditches direct water into 9 May 2013 sediment basin or other BMP structure designed to capture sediment while allow water to move through. 4.1.4 Culvert Inlet/Outlet Protection Inlets and outlets of culverts will be protected to prevent sediment build up within the culvert, thus maintaining culvert functionality. Temporary protection during construction can be implemented by installing straw bales or straw wattles around the inlet/outlet. For permanent protection, inlets/outlets shall be protected via rock armoring. Sediment accumulated at the inlet/outlet shall be removed as needed to ensure that there will be no blockage of the culvert. 4.1.5 Sediment Basins Sediment basins are structural BMPs installed to trap sediment that has been transported from other BMPs including, but not limited to, berms, perimeter diversion ditches, bar ditches, and drainage dips. Size and shape of each sediment basin shall depend on the specific location and surrounding topography of each site. 4.1.6 Armored Rundowns Armored rundowns are structural BMPs installed to minimize the erosion potential of the underlying substrate. Installation of armored rundowns can include, but is not limited to, inlet and outlet protection associated with sediment basins and ditches (i.e., sediment, diversion). 4.1.7 Straw Bale Barriers A straw bale barrier is a series of entrenched straw bales that are used to intercept and direct sheet flows. The barrier reduces runoff velocity and filters sediment from storm water as it moves through the barrier. The barrier may also be used to protect against erosion. 4.1.8 Water Bars Water bars can be a temporary or permanent structural BMP installed to direct runoff or run-on storm water away from construction activity. Bars slow velocity of water, and direct water into a sediment basin, or other BMP structure designed to capture sediment while allowing water to move through. 4.1.9 Tracking Pads Tracking pads are structural BMPs installed to trap sediment onsite prior to the respective vehicle leaving the location. Size and shape of the respective tracking pad(s) shall depend on the specific locations and surrounding topography of each site. 10 May 2013 4.2 Non-Structural Practices for Erosion and Sediment Control Non-structural practices implemented for erosion and sediment control will consist of permanent BMPs that will be utilized during all project phases from construction to interim reclamation, and ultimately to final stabilization. Non-structural controls typically include, but are not limited to, vegetative buffers, mulching, seeding of disturbed areas, erosion control blankets, and surface roughening. 4.2.1 Vegetative Buffers Vegetative buffers are areas of existing vegetation stands that are utilized as a permanent BMP. Vegetative buffers are located on any or all edges of a project boundary. They provide a filtering effect by minimizing velocity of storm water runoff enough to allow sediment to settle out while allowing clean water to continue with its natural drainage route. 4.2.2 Seeding of Disturbed Areas Seeding of disturbed areas will be implemented as a measure taken to achieve final stabilization. Upon construction completion, all disturbed areas to undergo reclamation shall be seeded. As a disturbed area is seeded, it will remain in the interim reclamation phase until the site has reached a vegetative cover area of 70% of pre-disturbance conditions. At this point, the site will be at the final stabilization phase. The main objective of drill seeding is to place the seed in the soil at the depth most favorable for seed germination. Topography will determine if seed will be applied via a drill seeder or if there is a need for broadcasting. Hand broadcasting is commonly used in areas too small for large equipment or if the terrain is too steep for equipment to work safely. Broadcast seeding throws the seeds randomly on the soil surface. This allows for a more mosaic plant population, but must be applied at twice the drill seed rate for successful germination. Once seed has been broadcast, raking or chaining the area will ensure seed to soil contact. Refer to Appendix E for the Project seed mixes and associated application rates. 4.2.3 Mulching Mulching is a non-structural BMP implemented to aid in seed establishment. After a disturbed area has been seeded, certified weed free straw mulch will be applied. Where accessible, the mulch will be crimped into the ground to provide additional soil stabilization. 4.2.4 Surface Roughening Surface roughening is an erosion control practice often used in conjunction with grading. Surface roughening involves increasing the relief of a bare soil surface with horizontal grooves by either stair-stepping (running parallel to the contour of the land) or using construction equipment to track the surface. Slopes that are not fine graded and left in a roughened condition also reduces erosion. Soil roughening reduces runoff velocity, increases infiltration, reduces erosion, traps sediment, and prepares the soil for seeding and planting; giving the seed an opportunity to germinate and establish. Used as a temporary or permanent BMP, surface roughening may take many different forms including, but not limited to, ripping, pocking and tracking. 11 May 2013 5.0 PHASED BMP IMPLEMENTATION During the Battlement Mesa development, each project will consist of a construction phase, an interim reclamation phase, and a final stabilization phase. There will be some BMPs implemented that can be utilized for each phase, however there will be certain controls implemented specifically for each phase. 5.1 Construction The construction phase of the project will consist of clearing the vegetation on the pad location, cut and fill activities for each pad and access road, and general grading. Appropriate BMPs will be installed for this phase of the construction. The following outlines the necessary steps of the construction phase: Well Pad(s) and Facilities • Vegetation Clearing: Vegetation will be removed and place around edge of disturbed area on down gradient side of fill slope. This will provide a brush barrier BMP for construction; • Topsoil will be utilized for berms or diversions; • Straw bale barriers or other temporary BMPs will be installed prior to construction; and • Concrete and truck washout area will be established, if applicable, once construction begins. Pipeline(s) • Pipelines will be installed along the road Right of Way when possible; • Temporary BMPs will be installed prior to construction; and • Permanent BMPs will be installed as ROW is reclaimed. 5.2 Interim Reclamation Interim reclamation will be the phase of each project between construction and final stabilization. A project will enter into interim reclamation when construction is completed, disturbed areas have been seeded, and permanent BMPs have been installed. Temporary BMPs that were implemented during the construction phase may continue to be maintained during interim reclamation. Projects will remain in interim reclamation until disturbed areas have been reclaimed to 70% of pre-disturbance conditions or otherwise permanently stabilized (i.e. graveled). Refer to Table 1 for BMPs implemented during the interim reclamation phase of each site. Well Pad(s) and Facilities • Topsoil will be used as material for swales or berms around the pad location; • Topsoil stockpile will be seeded and mulched immediately; and • Permanent BMPs will be installed, as temporary BMPs are removed if no longer a viable BMP. 12 May 2013 Pipeline(s) • Topsoil placement: Topsoil will be moved and redistributed across the surface of the disturbed area; • Vegetative material replacement/removal: Based upon BLM or landowner requirements, stripped vegetation may be hauled off-site or redistributed along the disturbed area; • Seeding: When applicable the disturbed ROW will be seeded post construction. The seed mix will vary depending on location and surface ownership and will generally match the surrounding vegetation. Refer to Appendix E for seed mixes and their respective application rate(s); and • Mulching: When applicable, all disturbed areas to be reclaimed will be mulched post seeding. A certified weed free straw will be crimped into the ROW to keep an adequate moisture level in the seedbed. 5.3 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. Areas which are not used for facilities, access roads, material storages 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. Other areas that may include facilities, access roads, material storage yards, and other work areas will be stabilized through the use of permanent, physical erosion reduction methods that include, but are not limited to: • Surface covering – covering of the soil surface with structures that inhibit contact of precipitation with the soil surface, which is generally considered to be placement of a structure (building or tank) over the soil surface. • 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 inspections reveal that the gravel surface is no longer effectively covering the soil surface, or performing its desired function. • Surface contouring/ditching – road surfaces that will not be graveled shall be constructed in a manner to prevent excessive erosion. Roads will be sloped in way to encourage positive drainage into bar ditches, and ultimately into sediment 13 May 2013 control structures. A compact, earthen berm will be constructed at the uphill side of the road slope. 6.0 MATERIALS HANDLING AND SPILL PREVENTION 6.1 Waste Management and Disposal The various construction activities mentioned in this SWMP will generate various other waste materials during the course of construction. These wastes typically include, but are not limited to, the following: • Trees and shrubs 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. Trees and shrubs will be piled along the toe of fill slopes to provide additional sediment control. Construction trash and debris will be collected in appropriate containers and hauled off-site for disposal in suitable landfills. Sanitary waste will be contained in portable toilets or other storage tanks with waste materials regularly pumped and transported off-site for proper disposal at approved facilities. 6.2 Fuels and Materials Management Petroleum Products 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 containers up to 55-gallons in volume, in secondary containment. 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. 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. Proper maintenance and safe storage practices will reduce the chance of petroleum products contaminating the 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 petroleum products will be applied: • All product containers will be clearly and properly labeled; • Drums will be kept off the ground within secondary containment and stored under cover when necessary; 14 May 2013 • Fuel tanks will be stored within areas containing 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); • Spill cleanup and containment materials (absorbent, shovels, etc.) will be readily available. 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. Construction personnel should be informed about proper storage and handling of materials during weekly subcontractor or safety meetings; • Provisions for absorbents are to be made available for use in fuel areas; and • Spill response will be immediate, contaminated soils will be contained and disposed of in accordance with applicable regulations. Notification procedures are to be used in the event of a material release or accident. At a minimum, the field supervisor should be notified. Depending on the nature of the spill and the material involved, Ursa staff, the CDPHE, downstream water users, or other agencies may also need to be notified. Notification Requirements: • Ursa Facility Manager • Project Environmental Coordinator/Regional Coordinator • State Agency in accordance with applicable regulations Hot Line Numbers: • WQCD toll-free 24-hour environmental emergency spill reporting line is (877)518-5608. • Colorado Department of Natural Resources oil and Gas conservation commission- oil spills 303-894-2100 • National Response Center 800-424-8802 A construction site spill report will include the following details of the incident: • The date and time of the incident; • A description of the material spilled; • Quantity spilled; • Circumstances that caused spill; • List of water bodies affected or potentially affected by spill; • Statement verifying whether an oil sheen is present; • Size of the affect area; • An estimate of depth; • Determination of possible migration of spill off Ursa property; • Statement of time of cleanup, methods being used, and personnel involved; and 15 May 2013 • Name of person to first observe spill, witnesses and their affiliations. Other Chemical Product Management Various 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 supervisor will maintain a lay-down 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 contamination. 6.3 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 appropriate off-site facilities. In the event that a spill occurs, prompt cleanup is required to minimize any commingling 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. Any waste product from maintenance will be contained and transported off site for disposal or recycling. There will be no major equipment overhauls conducted on site. Equipment will be transported off site when major overhauls are necessary. Cleanup of trash and discarded materials will be conducted at the end of each work day. Cleanup will consist of patrolling the road way, access areas, and other work areas to pick up trash, scrap debris, other discarded materials, along with any contaminated soil. Upon collection, these waste materials will be disposed of properly. 16 May 2013 7.0 DEDICATED CONCRETE OR ASPHALT BATCH PLANTS Not applicable to anticipated projects within the Battlement Mesa project area. 17 May 2013 8.0 VEHICLE TRACKING CONTROLS Vehicle track pads will be installed at all locations where it is considered necessary. Track pads will be approximately 20 feet wide and 20 feet long. This will eliminate sediment transport onto public roadways. 18 May 2013 9.0 INSPECTION AND MAINTENANCE PROCEDURES To meet the requirements of the Permit, inspection and maintenance of erosion and sediment controls must occur during the project. Continued inspection and maintenance is required for specific structures after construction is completed. The inspection program will include the following: 1. A certified person familiar with the SWMP and control measures will conduct the inspections. 2. Inspections will cover the following items within the construction site: • Disturbed areas without stabilization; • All structural and non-structural BMPs (temporary and permanent); • Material storage areas; • Surface water diversions; • Down gradient areas; and, • New access roads; • Site vehicle entrance/exit locations. 3. Inspections will occur at least once every 14 calendar days (during construction) and after a significant precipitation event, or snow melt event that causes potential for erosion. Once all measures have been taken to reach interim reclamation, inspections shall occur at least once every 30 calendar days. 4. A log of inspections will be maintained. 5. Water quality will be visually assessed for all receiving streams and discharge areas during each inspection. 6. Disturbed areas and material storage areas that are exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. 7. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. 8. Following each inspection, the SWMP will be modified as necessary to include additional controls designed to correct identified problems. Necessary revisions to the SWMP will be made within 7 days of the inspection. 9. An inspection report summarizing the scope of the inspection, the name of the person conducting the inspection, the date of the inspection, and observations relating to proper implementation will be prepared. Inspection reports will be retained for at least 3 years from the date that the site is finally stabilized. 10. Actions taken to modify any storm water control measure will be recorded and maintained with the SWMP. 11. If no deficiencies are found during the inspection, the report will contain certification that the site is in compliance with the SWMP. Maintenance Procedures Maintenance will include prompt repairs and/or adjustments to any erosion and sediment control structures that are deteriorating or found to be performing inadequately. BMP conditions and dates of BMP maintenance will be documented within the storm water inspection checklists. Repairs are to be made as soon as possible and prior to the next anticipated storm event. 19 May 2013 Inspection Forms Inspection forms shall be a part of this SWMP and will include information such as dates of maintenance/modifications of existing BMPs, installation of new BMPs, any site housekeeping requirements, and general comments. Refer to Appendix C for an example of the storm water inspection document. 20 May 2013 10.0 NON-STORMWATER DISCHARGES No allowable sources of non-storm water discharges are anticipated from the project. Some possible exceptions include, but are not limited to, fire prevention/suppression or dust control activities. Produced water will be collected and hauled off site to a proper storage facility and not discharged. 21 May 2013 11.0 CERTIFICATIONS 11.1 Owner/Applicant Certification I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.
