Manuals. Environmental Manual Chapter 430: Stormwater and Water Quality (PDF 341KB) - For legal requirements and policies pertaining to stormwater and water quality.. Temporary Erosion and Sediment Control Manual (TESCM) - Find policies for preventing stormwater-related erosion during construction and how to meet the requirements of the CSWGP. Highway Runoff Manual - To plan and design required by the 1200-C permit. BMPs are stormwater controls or measures that reduce pollutants at the source to prevent the pollution of stormwater runoff discharged from the site. These practices can also be used to divert stormwater runoff from areas of exposure to pollutants, or to treat stormwater runoff before discharge to receiving waters. The Highway Runoff Manual (HRM) provides guidance to direct the planning and design of stormwater management facilities for existing and new Washington State highways, rest areas, park-and-ride lots, ferry terminals, and highway maintenance facilities throughout the state. The HRM establishes minimum requirements and provides uniform technical guidance. It outlines WSDOT's policies for meeting the National Pollutant Discharge Elimination System (NPDES) Construction Stormwater General Permit requirements and the requirements in Volume II of the stormwater management manuals published by the Washington State Department of Ecology.
