NPDES Stormwater Discharge Permits -
Erosion and Sediment Control Manual and Inspector Guidance Booklet

In 2003 DEQ was awarded a grant from the U.S. Environmental Protection Agency (EPA) to conduct trainings and produce technical assistance materials on erosion and sediment control at construction sites. In partnership with the Association of Clean Water Agencies (ACWA) and a technical contractor (GeoSyntec Consultants), DEQ conducted training workshops in the Fall of 2004 and completed a statewide Erosion and Sediment Control Manual and related Inspector Guidance Booklet in April of 2005.

The Erosion and Sediment Control Manual is designed to assist construction site developers, engineers, designers and builders in identifying and implementing the most appropriate best management practices to minimize water quality impacts from their construction activities. More specifically, the manual should assist site developers in developing erosion and sediment control plans that that must be submitted for sites required to obtain a DEQ NPDES 1200-C Construction Stormwater permit and/or comply with local jurisdictional regulations.
