Plans B Sample CSWPP Worksheet Forms 2 SECTION 1 - OVERVIEW This Construction Stormwater Pollution Prevention (CSWPP) Plan describes the measures and BMPs to prevent the discharge of sediment-laden water and other pollutants associated with construction of the proposed Soos Creek Trail segment that extends from the current trail end at SE 192nd Street to SE 186th Street. This proposed shared-use trail segment is on King County Parks properties located within the City of Renton (COR) jurisdiction. See Figure 1 for the project vicinity map. This CSWPP Plan is prepared in conformance with requirement 2.1.2 of the City of Renton 2022 Surface Water Design Manual (City Drainage Manual). Figure 1 – Vicinity Map 3 The CSWPP Plan for the project is comprised of two separate plans: • Erosion and Sediment Control (ESC) Plan • Stormwater Pollution Prevention and Spill (SWPPS) Plan The ESC Plan consists of the TESC plan sheets containing City of Renton Erosion and Sediment Control Standard Notes included in the Permit Plan Set submitted under separate cover. The extracted TESC plan sheets are included in Appendix A. The SWPPS Plan includes the following three elements as required in the City Drainage Manual: • SWPPS site plan, including supporting documentation; • A pollution prevention report, and; • A spill prevention and cleanup report. These required elements are addressed in Sections 2, 3 and 4 below, respectively. Note that this SWPPS Plan is preliminary and is intended to identify potential requirements and measures. The contractor selected for this project will need to elaborate and/or propose alternative measures. Some details related to construction operations and methods are deferred to the contractor. For example, it is unknown at this time whether fueling or fluid storage will be conducted on-site. The contractor will be responsible for updating the SWPPS Plan as necessary, and for documenting these updates, to reflect the site conditions and construction operations. If a Washington State Department of Ecology Construction Stormwater General Permit (CSWGP) is required for the project, the contractor will be responsible for obtaining and implementing the permit (including monitoring and reporting). King County Parks may initially obtain the CSWGP, then transfer the permit to the Contractor for implementation. SECTION 2 – SWPPS SITE PLAN The site discharges through native vegetation to a wetland in the east along Big Soos Creek. The wetland runoff eventually discharges to Big Soos Creek, less than ¼ mile away (see Figure 2). There are no surface water quality impairments in the vicinity of the site, based on review of the current Washinton State DOE Clean Water Act Section 303d listing of impaired surface water bodies. There are two potential sources of stormwater pollution from the site: disturbed soil during grading, and fluids associated with construction equipment. The SWPPS Plan contains perimeter control measures (silt fence) and final site stabilization measures (seed and mulch) to address disturbed soils, temporary cover measures including temporary plastic cover over material stock piles, and additional BMPs as described below. Construction equipment pollutants, such as fuel, hydraulic fluids, and coolants must be controlled through appropriate storage, inspection, maintenance and spill control BMPs identified in the CSWPP Plan that will be prepared, implemented and managed by the prime contractor. The CSWPP Plan will also be implemented by any subcontractor(s), under supervision by the prime contractor. 4 Proposed erosion and sediment control measures and specifications are shown on the TESC plans (Appendix A) and described in this section. The following BMPs to prevent erosion and sedimentation at the site will be used. Note that BMP measures prefixes are associated with the Drainage Manual references. D.2.1.1 Clearing Limits: prior to clearing and grubbing, maintained for entire project D.2.1.2 Cover Measures: implemented throughout the project D.2.1.2.1 Surface Roughening, following clearing and grubbing D.2.1.2.2 Mulching, applied as temporary or permanent D.2.1.2.4 Plastic covering (alternative to nets and blankets) applied only to stockpiles D.2.1.2.5 Straw Wattles, applied and maintained for the entire project D.2.1.2.6 Temporary and permanent seeding D.2.1.3 Perimeter Protection D.2.1.3.1 Silt Fence, applied and maintained for the entire project D.2.1.4 Traffic Area Stabilization D.2.1.4.1 Stabilized Construction Entrance, applied and maintained for the entire project D.2.1.5 Sediment Retention D.2.1.5.1 Sediment Trap, applied if applicable to the site conditions D.2.1.5.3 Storm Drain Inlet Protection D.2.1.6 Surface Water Collection, applied if applicable to the site conditions D.2.1.6.1 Interceptor Dike and Swale D.2.1.6.4 Ditches D.2.1.7 Dewatering Control If construction dewatering is required, a sedimentation bag will be used to filter the water prior to discharge at a stabilized outlet. Baker tanks may be used to temporarily store water. D.2.1.8 Dust Control (water), throughout the project; emphasized during dry season D.2.1.9 Flow Control, not needed unless as directed by COR. If construction occurs in the wet season (October 1 to April 30), the following requirements apply: 1. Cover measures to be installed if an area is to remain unworked for more than two days. 2. Stockpiles and steep (steeper than 3H:1V) cut and fill slopes to be covered if unworked for more than 12 hours. 3. Exposed soils shall be stabilized at the end of the workday prior to a weekend, holiday or predicted rain event 4. Cover material sufficient to cover all exposed areas must be stockpiled on-site 5 5. Prior to wet season, review all disturbed areas to identify which ones can be seeded in preparation for winter rains; seed such areas within one week of start of wet season 6. 50 linear feet of silt fence per acre (175 feet minimum) must be stockpiled on-site 7. Construction road and parking lot stabilization 8. Sediment retention is required unless no offsite discharge is anticipated for the design flow. It is not anticipated that offsite discharge will occur. Construction runoff will not be concentrated and will disperse toward downstream vegetated flow path. 9. Surface water control is required unless no offsite discharge is anticipated for the design flow. It is not anticipated that concentrated offsite discharge will occur. Construction runoff will disperse toward downstream vegetated flow path. 10. Phasing must be evaluated for construction activity near surface waters. Trail construction phase was evaluated and determined to be unnecessary. 11. Dewatering water may be required to discharge to an approved sanitary sewer system, portable sand filter, or holding tanks. 12. ESC facilities to be inspected a minimum of twice per month and within 24 hours of a storm event. 13. Sediment removal from construction stormwater filtration or chemical treatment facilities: twice per wet season and at decommissioning SECTION 3 – STORMWATER POLLUTION PREVENTION REPORT The following describes construction activities with potential pollutants and applicable BMPs. Storage and Handling of Liquids Liquids that will potentially be stored on-site include petroleum products, fuels, solvents, and concrete admixtures. Storage locations, types and sizes of containers and secondary containment will be identified by the contractor. Storage and Stockpiling of Construction Materials and Wastes The following construction materials and waste may be generated and/or stored on-site: • Construction Materials: Framing lumber; fill soil; trench backfill • Wastes: Trees, woody vegetation; excavation spoils; demolished asphalt Staging and storage locations for these materials and any others required for the project will be identified by the contractor. Fueling The contractor will determine if and how equipment fueling is to be done on-site, the designated fueling area, and the location of any fuel storage. 6 On-site storage types and size will be determined by the contractor, as will the lighting and signage plan, if required. Containment methods, if needed, will conform to COR BMP D.2.2.4 Maintenance, Repairs, and Storage of Vehicles and Equipment Maintenance and repair areas, if any, will be identified by the contractor. Drip pans or plastic beneath vehicles are required in the maintenance area. Methods for collection, storage and disposal of vehicle/equipment fluids will be identified by the contractor, consistent with COR requirements. Designated vehicle maintenance areas will be posted with signage prohibiting vehicle washing. Concrete Saw Cutting, Slurry and Washwater Disposal Unless updated by the contractor, concrete slurry and truck washout water will not be generated on-site. No slurry or washout sumps are necessary. The site is identified to be in a wellhead protection area according to COR GIS maps. Slurry from saw cutting shall be vacuumed immediately. Contractor’s concrete washout off-site location shall also take into consideration of the wellhead protection area. Rinsing areas for concrete handling hand tools will be designated by the contractor on the SWPPS site plan. The contractor will identify methods of collecting, treating and disposing of wastewater from concrete grinding, and new concrete washing and curing, per the requirements of the project specifications. Handling of pH Elevated Water pH elevated water is not anticipated. The contractor will develop a contingency plan for treatment and disposal of high pH water, if encountered. Application of Chemicals including Pesticides and Fertilizers The contractor will provide a list of chemicals that may be used/applied at the site and will describe application methods and storage locations and methods. Any such locations will be shown on an updated SWPPS plan. APPLICABLE BMPs The following BMPs, at a minimum, from Appendix D of the City Drainage Manual will be applied to control pollutants at the site. Refer to Appendix D of the City Drainage Manual for details related to these BMPs. D.2.2.1 Concrete Handling Used during cast-in-place wall and sidewalk construction. D.2.2.2 Concrete Washout Area – offsite 7 D.2.2.4 Material Delivery, Storage and Containment Hazardous chemicals and liquids will be stored in a lockable structure(s) (e.g. shed). Liquid storage in quantities greater than 30 gallons will be provided with secondary containment capable of containing 110% of the volume of the largest container and 10% of the volume of all containers. Incompatible materials will be stored in separate structures. D.2.2.5 Construction Stormwater Chemical Treatment If selected, approval of the treatment system must be obtained from the Washington Department of Ecology and use approved chemicals and processes, such as chitosan- enhanced sand filtration. D.2.2.6 Construction Stormwater Filtration Construction stormwater filtration will likely not be feasible for the site sub-surface conditions. D.2.2.8 pH Control for High pH Water High pH water is not anticipated. If high pH water is produced, a permit to discharge to the Soos Creek Water and Sewer District sewer system will be sought. Segregation of high-pH runoff from other stormwater runoff will be implemented. D.2.2.10 Maintain Protective BMPs See maintenance standards. D.2.2.11 Manage the Project Inspections, monitoring and reporting will be as required by the Construction Stormwater General Permit (CSWGP) issued by the State Department of Ecology, and as requested by COR. The Contractor will be responsible for maintain, implementing and updating the SWPPS Plan in accordance with the CSWGP and COR. SECTION 4 – SPILL PREVENTION AND CLEANUP REPORT Potential sources of liquid spills at the site will likely be limited to small quantities of petroleum products, if fueling is performed on-site and fuel is stored on-site. Personnel responsible for spill prevention and cleanup have not been identified, and will be provided by the Contractor. Spill prevention BMPs (storage and secondary containment) will be monitored by regular (weekly) inspection. 8 Spill response procedures will be developed by the Contractor for the liquids planned to be used at the site. Spill response materials in quantities appropriate to the size of a potential spill will be stored on-site at a location to be determined by the Contractor and noted on the site plan. Records of inspections and spill response will be kept at the site, using the sample CSWPP Worksheet form (Reference Section 8-E of the City Drainage Manual) provided in Appendix B as a minimum. Contaminated water or soil will be stored on-site in drums until appropriate, lawful, disposal can be arranged REFERENCES City of Renton Surface Water Design Manual 2022 City of Renton GIS Maps King County GIS iMap Washington State Department of Ecology https://ecology.wa.gov/water-shorelines/water-quality/water-improvement/assessment-of- state-waters-303d WLWL WL WL WL W L WL WL WL WL WL WL WL WL WL WL WL WL WL 1 3 3 2 7 3 0 8 4 0 3323059010 3323059057 3323059073 APPROX.

PLAN - 214.00 NOTES: 1.CONDITION OF USE 1.1.CONSTRUCTION ENTRANCE SHALL BE STABILIZED WHEREVER TRAFFIC WILL BE LEAVING A CONSTRUCTION SITE AND TRAVELING ON PAVED ROADS OR OTHER PAVED AREAS WITHIN 1,000 FEET OF THE SITE. 1.2.FOR RESIDENTIAL CONSTRUCTION PROVIDE STABILIZED CONSTRUCTION ENTRANCES FOR EACH RESIDENCE IN ADDITION TO THE MAIN SUBDIVISION ENTRANCE. STABILIZED SURFACES SHALL BE OF SUFFICIENT LENGTH/WIDTH TO PROVIDE VEHICLE ACCESS/PARKING, BASED ON LOT SIZE/CONFIGURATION. 2.DESIGN AND INSTALLATION SPECIFICATIONS 2.1.A SEPARATION GEOTEXTILE SHALL BE PLACED UNDER THE SPALLS TO PREVENT FINE SEDIMENT FROM PUMPING UP INTO THE ROCK PAD. THE GEOTEXTILE SHALL MEET THE FOLLOWING STANDARDS: 2.2.DO NOT USE CRUSHED CONCRETE, CEMENT, OR CALCIUM CHLORIDE FOR CONSTRUCTION ENTRANCE STABILIZATION BECAUSE THESE PRODUCTS RAISE pH LEVELS IN STORMWATER AND CONCRETE DISCHARGE TO SURFACE WATERS OF THE STATE IS PROHIBITED. 2.3.HOG FUEL (WOOD BASED MULCH) MAY BE SUBSTITUTED FOR OR COMBINED WITH QUARRY SPALLS IN AREAS THAT WILL NOT BE USED FOR PERMANENT ROADS. HOG FUEL IS NOT RECOMMENDED FOR ENTRANCE STABILIZATION IN URBAN AREAS. THE INSPECTOR MAY AT ANY TIME REQUIRE THE USE OF QUARRY SPALLS IF THE HOG FUEL IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT OR IF THE HOG FUEL IS BEING CARRIED ONTO PAVEMENT. 2.4.FENCING SHALL BE INSTALLED AS NECESSARY TO RESTRICT TRAFFIC TO THE CONSTRUCTION ENTRANCE. 2.5.WHENEVER POSSIBLE, THE ENTRANCE SHALL BE CONSTRUCTED ON A FIRM, COMPACTED SUBGRADE. THIS CAN SUBSTANTIALLY INCREASE THE EFFECTIVENESS OF THE PAD AND REDUCE THE NEED FOR MAINTENANCE. 3.MAINTENANCE STANDARDS 3.1.QUARRY SPALLS SHALL BE ADDED IF THE PAD IS NO LONGER IN ACCORDANCE WITH THE SPECIFICATIONS. 3.2.IF THE ENTRANCE IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE STREETS FREE OF SEDIMENT SHALL BE USED. THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE ENTRANCE, OR THE INSTALLATION OF A WHEEL WASH. IF WASHING IS USED, IT SHALL BE DONE ON AN AREA COVERED WITH CRUSHED ROCK, AND WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND. 3.3.ANY SEDIMENT THAT IS TRACKED ONTO PAVEMENT SHALL BE REMOVED IMMEDIATELY BY SWEEPING. THE SEDIMENT COLLECTED BY SWEEPING SHALL BE REMOVED OR STABILIZED ON SITE. THE PAVEMENT SHALL NOT BE CLEANED BY WASHING DOWN THE STREET, EXCEPT WHEN SWEEPING IS INEFFECTIVE AND THERE IS A THREAT TO PUBLIC SAFETY. IF IT IS NECESSARY TO WASH THE STREETS, A SMALL SUMP MUST BE CONSTRUCTED. THE SEDIMENT WOULD THEN BE WASHED INTO THE SUMP WHERE IT CAN BE CONTROLLED AND DISCHARGED APPROPRIATELY. WASH WATER MUST BE PUMPED BACK ONTO THE SITE AND CANNOT DISCHARGE TO SYSTEMS TRIBUTARY TO SURFACE WATERS. 3.4.ANY QUARRY SPALLS THAT ARE LOOSENED FROM THE PAD AND END UP ON THE ROADWAY SHALL BE REMOVED IMMEDIATELY. 3.5.IF VEHICLES ARE ENTERING OR EXITING THE SITES AT POINTS OTHER THAN THE CONSTRUCTION ENTRANCE(S), FENCING SHALL BE INSTALLED TO CONTROL TRAFFIC. NOTES: 1.CONDITIONS OF USE 1.1.SILT FENCE MAY BE USED DOWNSLOPE OF ALL DISTURBED AREAS. 1.2.SILT FENCE IS NOT INTENDED TO TREAT CONCENTRATED FLOWS, NOR IS IT INTENDED TO TREAT SUBSTANTIAL AMOUNTS OF OVERLAND FLOW. ANY CONCENTRATED FLOW MUST BE CONVEYED THROUGH THE DRAINAGE SYSTEM TO A SEDIMENT TRAP OR POND. 2.DESIGN AND INSTALLATION SPECIFICATIONS 2.1.THE GEOTEXTILE USED MUST MEET THE STANDARD LISTED BELLOW. A COPY OF THE MANUFACTURER'S FABRIC SPECIFICATIONS MUST BE AVAILABLE ON SITE. 2.2.STANDARD STRENGTH FABRIC REQUIRES WIRE BACKING TO INCREASE THE STRENGTH OF THE FENCE. WIRE BACKING OR CLOSER POST SPACING MAY BE REQUIRED FOR EXTRA STRENGTH FABRIC IF FIELD PERFORMANCE WARRANTS A STRONGER FENCE. 2.3.WHERE THE FENCE IS INSTALLED, THE SLOPE SHALL NOT BE STEEPER THAN 2H:1V 2.4.IF A TYPICAL SILT FENCE IS USED, THE STANDARD 4"X4" TRENCH MAY BE REDUCED AS LONG AS THE BOTTOM 8 INCHES OF THE SILT FENCE FABRIC IS WELL BURIED AND SECURE IN A TRENCH THAT STABILIZES THE FENCE AND DOES NOT ALLOW WATER TO BYPASS OR UNDERMINE THE SILT FENCE. 2.5.FILTER FABRIC FENCES SHALL BE INSTALLED ALONG CONTOURS WHENEVER POSSIBLE. 3.MAINTENANCE STANDARDS 3.1.ANY DAMAGE SHALL BE REPAIRED IMMEDIATELY. 3.2.IF CONCENTRATED FLOWS ARE EVIDENT UPHILL OF THE FENCE, THEY MUST BE INTERCEPTED AND CONVEYED TO A SEDIMENT TRAP OR POND. 3.3.IT IS IMPORTANT TO CHECK THE UPHILL SIDE OF THE FENCE FOR SIGNS OF THE FENCE CLOGGING AND ACTING AS A BARRIER TO FLOW AND THEN CAUSING CHANNELIZATION OF FLOWS PARALLEL TO THE FENCE. IF THIS OCCURS, REPLACE THE FENCE OR REMOVE THE TRAPPED SEDIMENT. 3.4.SEDIMENT MUST BE REMOVED WHEN SEDIMENT IS 6 INCHES HIGH. 3.5.IF THE FILTER FABRIC (GEOTEXTILE) HAS DETERIORATED DUE TO ULTRAVIOLET BREAKDOWN, IT SHALL BE REPLACED. CONSTRUCTION ENTRANCE NOTES: 1.DRIVEWAYS SHALL BE PAVED TO THE EDGE OF THE RIGHT-OF WAY PRIOR TO INSTALLATION OF THE CONSTRUCTION ENTRANCE TO AVOID DAMAGING OF THE ROADWAY. 2.IT IS RECOMMENDED THAT THE ENTRANCE BE CROWNED SO THAT RUNOFF DRAINS OFF THE PAD. 1 C-007 STABILIZED CONSTRUCTION ENTRANCE NOT TO SCALE REFERENCE: CITY OF RENTON STD.
