compliance with Special Conditions S4(Monitoring)and S9 (SWPPPs)will <br /> constitute compliance with the approved TMDL. <br /> c. Where an applicable TMDL has not specified a waste load allocation for <br /> construction stormwater discharges,but has not excluded these discharges, <br /> compliance with Special Conditions S4(Monitoring)and S9 (SWPPPs)will <br /> constitute compliance with the approved TMDL. <br /> d. Where an applicable TMDL specifically precludes or prohibits discharges from <br /> construction activity, the operator is not eligible for coverage under this permit. <br /> 2. Applicable TMDL means a TMDL for turbidity, fine sediment,high pH, or <br /> phosphorus that is completed and approved by EPA before January 1,2016, or <br /> before the date the operator's complete permit application is received by Ecology, <br /> whichever is later. TMDL,s completed after the operator's complete permit <br /> application is received by Ecology become applicable to the Permittee only if they <br /> are imposed through an administrative order by Ecology,or through a modification <br /> of permit coverage. <br /> S9. STORMWATER POLLUTION PREVENTION PLAN <br /> The Permittee must prepare and properly implement an adequate Stormwater Pollution <br /> Prevention Plan(SWPPP) for construction activity in accordance with the requirements of <br /> this permit beginning with initial soil disturbance and until final stabilization. <br /> A. The Permittee's SWPPP must meet the following objectives: <br /> 1. To implement best management practices(BMPs)to prevent erosion and <br /> sedimentation, and to identify,reduce, eliminate or prevent stormwater <br /> contamination and water pollution from construction activity. <br /> 2. To prevent violations of surface water quality, ground water quality,or sediment <br /> management standards. <br /> 3. To control peak volumetric flow rates and velocities of stormwater discharges. <br /> B. General Requirements <br /> 1. The SWPPP must include a narrative and drawings. All BMPs must be clearly <br /> referenced in the narrative and marked on the drawings. The SWPPP narrative <br /> must include documentation to explain and justify the pollution prevention <br /> decisions made for the project. Documentation must include: <br /> a. Information about existing site conditions(topography,drainage, soils, <br /> vegetation, etc.). <br /> b. Potential erosion problem areas. <br /> c. The 13 elements of a SWPPP in Special Condition S9.D.1-13, including BMPs <br /> used to address each element. <br /> Construction Stormwater General Permit <br /> Page 27 <br />
