3.0 CONSTRUCTION STORM WATER BMPS <br />The 12 standard BMPs outlined in the Department of Ecology (DOE) Storm Water Management <br />Manual for Western Washington, Volume II, are used as the primary approach for erosion and <br />sediment control are summarized in the following section. <br />Because the standard BMPs to be used on the site include full capture and infiltration of storm <br />water onsite, with the only potential for discharge being emergency overflow, it has been <br />determined that Alternate BMPs are not applicable to this site. Multiple standard BMPs have <br />been included for each of the BMP elements. Accordingly, Appendix C"Alternate BMPs" per <br />the DOE SWPPP guidance has not been utilized for this project. <br />3.1 12 BMP Elements <br />3.1.1 Element #1 — Mark Clearing Limits <br />Prior to land clearing activities, mark all clearing limits in the field with flagging or high visibility <br />fences, stake and wire, or silt fences, to protect vegetation to remain, adjacent roadways and <br />adjacent properties. Retain existing vegetation to the maximum extent practicable. Protect <br />existing vegetation to remain using high visibility fence. Mark clearing limits, both in the field <br />and on the Plans. The BMPs relevant to marking the clearing limits that will be applied for this <br />project include: <br />• BMP C101: Preserving Natural Vegetation <br />• BMP C102: Buffer Zones <br />• BMP C103: High Visibility Plastic or Metal Fencing <br />• BMP C104: Stake and Wire Fence <br />• BMP C233: Silt Fence <br />TESC Plan and SWPPP 2 June 2015 <br />American Legion Memorial Park Page 7 <br />
