Construction Site Control

Uncontrolled urban runoff from construction sites can significantly impact the water quality of local streams and creeks. These water quality impacts, which are usually seen as excessive erosion and sedimentation, must be controlled in accordance with the Program’s NPDES permit.

The MRP Provision C.6 requires member agencies to implement a construction site inspection and control program at all construction sites, with follow-up and enforcement, as needed. The provision identifies specific elements of the program including legal authority through local ordinances/municipal code, six Best Management Practices (BMPs) categories, a plan approval process, minimum inspection frequencies, inspection content, data tracking and reporting and staff training.

Co-permittees continue to implement the MRP requirements by conducting reviews of erosion control plans, requiring General Permit coverage, conducting routine (including pre-wet season) and as-needed construction site inspections, documenting and reporting violations and enforcement response, and training inspectors.  The Program annually co-sponsors and/or conducts a Construction Site Management Workshop to assist Co-permittees with inspector training needs, provides guidance on annual reporting requirements, and assists Co-permittees with construction-related questions and issues as needed. 

Site Controls for Constructed-Related Activities

To assist dischargers in managing potential pollutants from construction-related activities, various regulatory agencies and organizations ((including SCVURPPP) have developed informational manuals, brochures and guidance documents to comply with NPDES stormwater requirements. Information provided on this website includes available resources which detail best management practices (BMPs) for construction sites and information on how to prepare a Storm Water Pollution Prevention Plan.
