A SWPPP is designed to be a stand-alone document that addresses construction stormwater management concerns. This
document is required to be kept by the contractor performing the work at the jobsite for reference and update during
the life of ,hfproject. Construction BM P's must be indicated on the stormwater site plan. REFERENCE BlA includes
diagra s of common BM P's that may be used on the site plan.
My completed SWPPP (WORKSHEET Bl or equivalent) is included in this application packet!
Minimum Requirement# 3 : Source Control of Pollution (not construction related)
The intent of source control is to prevent stormwater from coming in contact with pollutants. Source control BMPs
can be operational or structural in nature. A roof over a material storage area is an example of a structural source
control BMP. Washing your vehicle on the lawn rather than in the street is an operational BMP. This requirement
is generally not applicable to Single Family Residences (SFRs); however, ways to minimize pollution from moving
downstream should be considered during the design phase of every project. Specifications on standard source control
BMPs that are applicable to various commercial and industrial-type facilities can be found in Volume IV of the 2014
Stormwater Management Manual for Western Washington (SWMMWW) (continued on page 2).
