MAINTENANCE AND INSPECTION Maintenance and Inspection Practices Inspections will be conducted at least one time per week and after a storm event of 0.50 inches or greater. All controls will be maintained in good working order. Necessary repairs will be initiated within 24 hours of the site inspection report or as soon as field conditions allow access. Where work has been suspended due to frozen ground conditions, the required inspections and maintenance must take place as soon as runoff occurs at the site or prior to resuming construction, whichever comes first. Where parts of the construction site have undergone final stabilization, but work remains on other parts of the site, inspections of the stabilized areas may be reduced to once per month. Silt fence will be inspected for depth of sediment and for tears in order to ensure the fabric is securely anchored. Sediment buildup will be removed from the silt fence when it reaches of 13 of the height of the silt fence. All silt fences must be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches of 13 of the height of the fence. Sediment basins and traps will be checked. Sediment will be removed when the depth reaches approximately 50 percent of the structure's capacity. Check dams will be inspected for stability. Sediment will be removed when the depth reaches 12 the height of the dam. All seeded areas will be checked for bare spots, washouts, and vigorous growth free of significant weed infestations. Surface waters, including drainage ditches and conveyance systems, must be inspected for evidence of sediment being deposited by erosion. Construction site vehicle exit locations must be inspected for evidence of off-site sediment tracking onto paved surfaces. Tracked sediment must be removed from all off-site paved surfaces within 24 hours of discovery. Disturbed areas will be checked for stabilization. Stabilization measures shall be initiated as soon as construction activity in that portion of the site has temporarily or permanently ceased. The normal wetted perimeter of any temporary or permanent drainage ditch or swale that drains water from any portion of the construction site, or diverts water around the site, must be stabilized within 200 lineal feet from the property edge, or from the point of discharge into any surface water. Stabilization of the last 200 lineal feet must be completed within 24 hours after connection to a surface water. Stabilization of the remaining portions of any temporary or permanent ditches or swales must be completed within 14 days after connecting to a surface water and construction in that portion of the ditch has temporarily or permanently ceased. Temporary or permanent ditches or swales that are being used as a sediment containment system (with properly designed rock ditch checks, bio rolls, silt dikes, etc.) do not need to be stabilized. These areas must be stabilized within 24 hours after no longer being used as a sediment containment system. Pipe outlets must be provided with temporary or permanent energy dissipation within 24 hours after connection to a surface water. Discharge procedures for water control and dewatering operations will be inspected. If the water cannot be discharged to a sedimentation basin prior to entering the surface water, it must be treated with the appropriate BMPs, such that the discharge does not adversely affect the receiving water or downstream landowners. Inspection and maintenance reports will be completed for each site inspection, this form will also be used to document changes to the SWMP. The report shall include the date and amount of precipitation or snowmelt events that cause surface erosion. A copy of the completed inspection form will be filed with the SWMP documents. The Contractor's site superintendent is responsible for inspection. Maintenance and repair activities are the responsibility of the Contractor.

STORM WATER POLLUTION PREVENTION PLAN The Colorado General Permit Authorization to Discharge Stormwater Associated with Construction Activity (Permit # ) ) ) issued on / / shall apply / / shall apply shall apply for this project. ABBREVIATIONS CDPHE: Colorado Department of Public Health and Environment CDNR: Colorado Department of Natural Resources USFWS: United States Fish and Wildlife Service SWMP: Storm Water Management Plan LOCATION/NARRATIVE Location: See Sheet 1 for the location of this project. Project Limits: See Sheet 2 of this plan for the project limits. These sheets cover the earthwork for the two ponds and the water control structure. PROJECT CONTACTS SWMP Administrator: Kevin Warner, P.E. Regional Engineer Ducks Unlimited Cell: 970-590-1545 Email: [email protected] The Contractor is responsible for implementation of the SWMP and installation, inspection and maintenance of the erosion prevention and sediment control BMP's before and during construction. Contractor Name: . . . Company: . . . Telephone Number: . . . Email: . . . SPILL NOTIFICATION In the event of a spill, the contractor's site superintendent will make the appropriate notificiaton(s), consistent with the following procedures: 1. A reportable spill is a quantity of more than 5 A reportable spill is a quantity of more than 5 gallons of petroleum which must be reported immediately to the CDPHE. 2. Any spill of oil or hazardous substance to waters of Any spill of oil or hazardous substance to waters of the state must be reported immediately by telephone to the CDPHE. 3. Colorado Environment Release and Reporting Line: Colorado Environment Release and Reporting Line: 24 Hour (877) 518-5608 POTENTIAL POLLUTION SOURCES Heavy machinery will be operated on the project site requiring the use of fuel trucks. Contamination due to fuel spills and oil leaks is possible due to the large volume of work being performed. Day to day cleaning and maintenance of equipment has the potential to impact stormwater quality. Delivery of site materials also has potential for impacting runoff quality. Another potential pollution source is sediment transport from earthwork. POLLUTION PREVENTION MANAGEMENT MEASURES Solid Wastes (None anticipated): Collected sediment, asphalt, and concrete millings, floating debris, paper, plastic, fabric, construction and and demolition debris and other wastes must be disposed of properly and must comply with the CDPHE disposal requirements. Hazardous Materials (None anticipated): Oil, gasoline, paint and any hazardous substances must be properly stored, including secondary containment, to prevent spills, leaks or other discharge. Restricted access to storage areas must be provided to prevent vandalism. Storage and disposal of hazardous waste must be in compliance with CDPHE regulations. Vehicle Washing: External washing of trucks and other construction vehicles must be limited to a defined area of the site. Runoff must be contained and waste properly disposed of. No engine degreasing is allowed on site. Concrete Washout Onsite (No concrete anticipated): All liquid and solid wastes generated by concrete washout operation must be contained in a leak-proof containment facility or impermeable liner. A compacted clay liner that does not allow washout liquids to enter ground water is considered an impermeable liner. The liquid and solid wastes must not contact the ground, and there must not be runoff from the concrete washout operation or areas. Liquid and solid wastes must be disposed of properly and in compliance with CDPHE regulations. A sign must be installed adjacent to each washout facility to inform concrete equipment operators to utilize the proper facilities.

Storm Water Management: Storm water management will be handled by temporary controls outlined in "EROSION AND SEDIMENT CONTROLS" above, and any permanent controls needed to meet permanent storm water management needs in the post construction period. SITE DESCRIPTION EXISTING CONDITIONS: The portion of the Jackson State Wildlife Area that the work will be performed is considered a wildlife nature preserve. PROJECT DESCRIPTION: The purpose of the project is to restore and enhance shallow-water wetlands. The project will consist of strategic earth-moving to increase area in Pond #1, Pond #2, and combine Pond #7 and Pond #8. DESCRIPTION OF CONSTRUCTION ACTIVITIES The proposed construction activities will provide water level management to the site. Through this management more desirable wetlands will be created. Major Soil Disturbing Activities (check all that apply): X Clearing & Grubbing Clearing & Grubbing X Grading & Shaping Grading & Shaping X Cutting & Filling Cutting & Filling Other (describe): Other (describe): Discharges to Special Or Impaired Waters: The project does not have a discharge point within 1 mile of a special water or a water that is impaired for sediment or a sediment related parameter of the permit. Discharges to Calcareous Fen: The project does not have a discharge to a Calcareous fen. Endangered or Threatened Species: The project area has not been identified for endangered or threatened species. Historic Places or Archeological Sites: Historical places or archeological sites have been addressed by the USFWS.

ORDER OF CONSTRUCTION ACTIVITIES (Stabilization measures shall be initiated as soon as possible, but in no case later than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased.) Install initial erosion and sediment control measures. Proceed with site grading and construction activities. Stabilize areas disturbed by construction activities with temporary erosion and sediment control measures. Complete final grading. Complete permanent erosion and sediment control measures. ESTIMATED PROJECT AREA QUANTITIES Total Project Area: 248 Acres Total Area to Be Disturbed: 15 Acres Existing Impervious Area: 0.0 Acres Proposed Impervious Area: 0.0 Acres EXISTING GROUND COVER Currently the site is a wildlife nature preserve with eight ponds on-site. NON-STORMWATER DISCHARGE None. RECEIVING WATER Runoff from the site is retained by the existing pond system. During a flooding event, water from the project area would ultimately drain into Jackson Reservoir. STREAM CROSSINGS LOCATED WITHIN THE CONSTRUCTION SITE BOUNDARY None.

SITE MAP See Sheet 1 (Cover Sheet) for vicinity and location maps. See Sheet 2 for overall site map. LOCATION OF SWMP REQUIREMENTS IN PROJECT PLAN See the Erosion and Sediment Control notes and details on sheets 9 & 10. FINAL STABILIZATION AND LONGTERM STORMWATER MANAGEMENT Following site construction, the goal is to achieve a stabilized cover condition to provide long-term stormwater protection. Stabilization is quantified by achieving uniform cover equal to 70% of the pre-disturbance condition. The post-construction condition of the site shall be that the majority of the disturbed area will be compacted soil and seeded. Once the seeding takes, this shall virtually eliminate erosion from the site. Permanent seeding with mulching is installed as needed. Drainage ditches, pans, and culverts shall be cleaned of debris and sediment. Repair eroded sloped or drainage paths by backfilling. Remove all silt fences following establishment of permanent stable vegetation. CONSTRUCTION CHANGES When changes are made to the construction project that will require alterations in the temporary erosion controls of the site, the Storm Water Management Plan (SWMP) will be amended to provide appropriate protection to disturbed areas, all storm water structures, and adjacent waters. The SWMP will be retained in a designated place for review over the course of the project.
