1. Discharges to a waterbody that is subject to a Total Maximum Daily Load (TMDL)for turbidity,fine sediment, high pH,or phosphorus must be consistent with the TMDL. Refer to http://www.ecy.wa.gov/programs/wq/tmdl/TMDLsbyWria/TMDLbyWria.html for more information on TMDLs. L a. Where an applicable TMDL sets specific waste load allocations or requirements for discharges covered by this permit, discharges must be consistent with any specific waste load allocations or requirements established by the applicable TMDL. i. The Permittee must sample discharges weekly, unless otherwise specified by the TMDL, to evaluate compliance with the specific waste load allocations or requirements. i H. Analytical methods used to meet the monitoring requirements must conform l; s to the latest revision of the Guidelines Establishing Test Procedures for the Analysis of Pollutants contained in 40 CFR Part 136. j r iii. Turbidity and pH methods need not be accredited or registered unless s conducted at a laboratory which must otherwise be accredited or registered. b. Where an applicable TMDL has established a general waste load allocation for construction stormwater discharges, but has not identified specific requirements, I compliance with Special Conditions S4(Monitoring) and S9 (SWPPPs)will constitute compliance with the approved TMDL. E c. Where an applicable TMDL has not specified a waste load allocation for construction is stormwater discharges, but has not excluded these discharges, compliance with Special Conditions S4 (Monitoring) and S9 (SWPPPs)will constitute compliance with f the approved TMDL. j r d. Where an applicable TMDL specifically precludes or prohibits discharges from construction activity,the operator is not eligible for coverage under this permit. i i l I � S9. STORMWATER POLLUTION PREVENTION PLAN f . „ F The Permittee must prepare and properly implement an adequate Stormwater Pollution Prevention Plan (SWPPP)for construction activity in accordance with the requirements of this I permit beginning with initial soil disturbance and until final stabilization. A. The Permittee's SWPPP must meet the following objectives: ii E 1. To identify best management practices(BMPs)which prevent erosion and sedimentation, j and to reduce, eliminate or prevent stormwater contamination and water pollution from i construction activity. 2. To prevent violations of surface water quality, groundwater quality, or sediment management standards. 3. To control peak volumetric flow rates and velocities of stormwater discharges. i Construction 5tormwater General Permit Page 23
