WASTE WATER FORCEMAIN KFB KGA KFB R16.115896 46 STORMWATER POLLUTION PREVENTION PLAN (SWPPP) PERMANENT STORMWATER MANAGEMENT SYSTEM: Type of storm water management used if more than 1 acre of new impervious surface is created: DOCUMENT RETENTION The following documentation will be retained for a period of not less than 3-years from the date of submittal of the NOT in compliance with Part III.E of the Permit. 1.The final SWPPP 2.Copies of all stormwater related permits required for the project 3.Records of all inspection and maintenance conducted during construction 4.Copies of all permanent operation and maintenance agreements; including all right‐of‐way, contracts, covenants and other binding requirements regarding perpetual maintenance, and 5.All required calculations for design of the temporary and permanent BMPs. PROJECTLOCATION 1-MILEBOUNDARY RECEIVINGWATERS WASTE WATER FORCEMAIN CITY OF ELK RIVER SHERBURNE COUNTY, MINNESOTA PROJECT LOCATION: RECEIVING WATERS: Receiving waters, including surface water, wetlands, Public Waters, and stormwater ponds, are identified on the USGS 7.5 min quad map within one mile of the project boundary. Receiving waters that are impaired, the impairment, and WLA are listed as follows. All specific BMPs relative to construction activities listed in this permit for special and impaired waters have been incorporated into this plan. All specific BMPs listed in approved TMDLs and those BMPs listed for construction related waste load allocations have also been incorporated. DESCRIPTION OF CONSTRUCTION ACTIVITIES AND STORMWATER MANAGEMENT: Construction activities include: trenchless forcemain, lift station, parking area, temporary erosion and sediment control, and permanent stabilization. The proposed project is to construct a lift station and wastewater forcemain to convey the landfill leachate to the Elk River wastewater treatment system. The existing drainage will not be modified due to construction related activities. The majority of the project will be constructed using trenchless technology. The open trench locations are shown in the above figure.IMPLEMENTATION SCHEDULE AND PHASING: The Contractor is required to provide an updated schedule and site management plan meeting the minimum requirements of Section 1717.2.C and 1717.2.D of the Minnesota 2016 Standard Specifications. 1)Submit SWPPP Updates to Engineer. Submittal shall include any requested changes to the SWPPP, including but not limited to: Trained Personnel, Locations for Stockpiles, Concrete Washout, Sanitation Facilities, Types and Locations of Erosion & Sediment Control. Failure to submit updates shall be considered acceptance of the SWPPP as designed with no changes. 2)Install perimeter sediment control, inlet protection, and construction exit. 3)Install trenchless forcemain, pretect all access pits with erosion control measures 4)Install lift station 5)connect existing pipes to new wastewater system 6)Add additional temporary BMPs as necessary during construction based on inspection reports. 7)Ensure final stabilization measures are complete. 8)Provide digital copy of all Field SWPPP Documentation including Inspection Reports and SWPPP Revisions to the Owner. 9)Submit Notice of Termination (NOT) to MPCA. NOTE: The NOT must be submitted to MPCA before Final Stabilization is considered complete. LEGEND SPECIAL ENVIRONMENTAL CONSIDERATIONS: The SWPPP Designer and Construction SWPPP Manager must have appropriate training. Documentation showing training commensurate with the job duties and responsibilities is required to be included in the SWPPP prior to any work beginning on the site. Training documentation for the SWPPP Designer is included on this sheet. The Contractor shall attach training documentation to this SWPPP for the Construction SWPPP Manager prior to the start of construction. This information shall be kept up to date until the project NOT is filed. GENERAL STORMWATER DISCHARGE REQUIREMENTS All requirements listed in Part III of the Permit for the design of the permanent stormwater management system and discharge have been included in the preparation of this SWPPP. These include but are not limited to:: 1.The expected amount, frequency, intensity, and duration of precipitation. 2.The nature of stormwater runoff and run-on at the site 3.Peak flow rates and stormwater volumes to minimize erosion at outlets and downstream channel and stream bank erosion. 4.The range of soil particle sizes expected to be present on the site. RESPONSIBLE PARTIES: The Contractor and Owner must apply for coverage under the MPCA's General Stormwater Permit for Construction Activity as required by the National Pollutant Discharge Elimination System (NPDES) Phase II program. Coverage under the permit will begin automatically 7 calendar days after the electronic submittal date or after the postmarked date of a complete application. [Longer time frames apply to sites that disturb areas greater than 50 acres.] The Contractor shall provide one or more trained Construction SWPPP Manager(s) knowledgeable and experienced in the application of erosion prevention and sediment control BMPs that will oversee the implementation of the SWPPP, and the installation, inspection and maintenance of the erosion prevention and sediment control BMPs. A Construction SWPPP Manager must be available for an on-site inspection within 72 hours upon request by the MPCA. ADDITIONAL COMPENSATION Payment for all work associated with Erosion and Sediment Control shall be as described in the Project Manual. Unless otherwise authorized by the Owner no additional payment shall be made for any work required to administer and maintain the site erosion and sediment control in compliance with the Minnesota Pollution Control Agency (MPCA) - General Stormwater Permit for Construction Activity (MN R100001) including but not limited to inspection, maintenance, and removal of BMPs or addition of BMPs to accommodate Contractor phasing.
