II-3 Construction Stormwater BMPs <br />11-3.1 A Summary of Construction Stormwater <br />BMPs <br />This chapter contains standards and specifications for temporary BMPs, used as appropriate during <br />the construction phase of a project. Often using BMPs in combination is the best method to meet <br />Construction Stormwater Pollution Prevention Plan (Construction SWPPP) requirements. <br />The standards and specifications in this chapter are not intended to limit innovative efforts to effect- <br />ively control erosion and sedimentation. Construction SWPPPs can contain experimental BMPs or <br />make minor modifications to standard BMPs. However, the permitting authority (state, local, or both) <br />must approve such practices before use. Experimental and modified BMPs must achieve the same <br />or better performance than the BMPs listed below. <br />None of the BMPs listed below will work successfully throughout the construction project without <br />inspection and maintenance. Regular inspections to identify problems with the operation of each <br />BMP, and the timely repair of any problems are essential to the continued operation of the BMPs. As <br />site conditions change, BMPs must change to remain in compliance. <br />Construction stormwater BMPs are divided into two categories: Construction Source Control BMPs <br />and Construction Runoff BMPs. <br />Table II-3.1: Construction Stormwater BMPs by SWPPP Element shows the relationship of the Con- <br />struction Stormwater BMPs to the Construction SWPPP Elements described in 1-3.4.2 MR2: Con- <br />struction Stormwater Pollution Prevention Plan (SWPPP). <br />Table II-3.1: Construction Stormwater BMPs by SWPPP Element <br />Construction Storm- <br />water BMP <br />Construction SWPPP Element # <br />#1 <br />#2 <br />#3 <br />#4 <br />#5 <br />#6 <br />#7 <br />#8 <br />#9 <br />#10 <br />#11 <br />#12 <br />#13 <br />Construction Source Control BMPs <br />BMP C101: Preserving <br />Natural Vegetation <br />BMP C102: Buffer <br />Zones <br />BMP C103: High -Vis- <br />V <br />V <br />ibility Fence <br />BMP C105: Stabilized <br />✓ <br />Construction Access <br />C106: Wheel <br />Wash <br />✓ <br />2019 Stormwater Management Manual for Western Washington <br />Volume 11- Chapter 3 - Page 267 <br />
