|Post Construction Stormwater Program (PCSP)
NCDOT is required by its National Pollutant Discharge Elimination System (NPDES) permit to implement a Post-Construction Stormwater Program (PCSP). The primary objective of the PCSP is to manage stormwater runoff from NCDOT projects by requiring structural and non-structural best management practices to protect the water quality of NC's lakes, streams, rivers, and estuaries. The requirements described in the PCSP apply to NCDOT projects which increase built-upon area. As required by the PCSP, NCDOT implements structural best management practices (BMP) described in the BMP Toolbox and/or non-structural pollution minimization measures described both in the PCSP and the BMP Toolbox. For most projects, documentation that the PCSP requirements were followed is provided through the preparation of a Stormwater Management Plan.
