2 Construction Stormwater Best Management Practices (BMPs) <br /> Describe the BMPs identified to control pollutants in stormwater discharges. Depending on the <br /> site, multiple BMPs for each element may be necessary. For each element identified: <br /> • Clearly describe the control measure(s). <br /> • Describe the implementation sequence. <br /> • Describe the inspection and maintenance procedures for that specific BMP. <br /> • Identify the responsible party for maintaining BMPs (if your SWPPP is shared by multiple <br /> operators, indicate the operator responsible for each BMP). <br /> Categorize each BMP under one of the following elements as listed below: <br /> 1. Preserve Vegetation / Mark Clearing Limits <br /> 2. Establish Construction Access <br /> 3. Control Flow Rates <br /> 4. Install Sediment Controls <br /> 5. Stabilize Soils <br /> 6. Protect Slopes <br /> 7. Protect Drain Inlets <br /> 8. Stabilize Channels and Outfalls <br /> 9. Control Pollutants <br /> 10. Control Dewatering <br /> 11. Maintain BMPs <br /> 12. Manage the Project <br /> 13. Protect Low Impact Development <br /> • BMPs must be consistent with the most current edition of the Stormwater Management <br /> Manual for Western Washington (SWMMWW) at sites west of the crest of the Cascade <br /> Mountains; the Stormwater Management Manual for Eastern Washington (SWMMEW) <br /> for sites east of the crest of the Cascade Mountains; or other Ecology-approved manual. <br /> • Note the location of each BMP on your Site Map in Appendix A. <br /> • Include the corresponding Ecology source control BMPs and runoff conveyance and <br /> treatment BMPs in Appendix B. <br /> o SWMMWW Volume II Chapter 4 Sections 4.1 and 4.2 — <br /> https://fortress.wa.gov/ecy/,publications/SummaryPages/1410055.html or <br /> o SWMMEW Chapter 7 Section 7.3.1 and 7.3.2— <br /> http://www.ecy.wa.gov/biblio/0410076.html <br /> If it can be justified that a particular element does not apply to the project site, include a written <br /> justification in lieu of the BMP description in the text for the appropriate element. <br /> The SWPPP is a living document reflecting current conditions and changes throughout the life <br /> of the project. These changes may be informal (i.e., hand-written notes and deletions). Update <br /> the SWPPP when the CESCL has noted a deficiency in BMPs or deviation from original design. <br /> Page 17 <br />
