National Pollutant Discharge Elimination System (NPDES)

National Menu of Best Management Practices (BMPs) for Stormwater-Construction

Disclaimer: The BMP examples and references included on these fact sheets are not intended to be comprehensive. Additionally, the list of BMPs is not all-inclusive, and it does not preclude MS4s from using other technically sound practices.

Uncontrolled stormwater runoff from construction sites can significantly impact rivers, lakes, and estuaries. Sediment in waterbodies from construction sites can reduce the amount of sunlight reaching aquatic plants, clog fish gills, smother aquatic habitat and spawning areas, and impede navigation.

Phase II municipal separate storm sewer systems (MS4s) are required to develop a program to reduce pollutants in stormwater runoff to the MS4 for construction sites disturbing one or more acres. This primarily includes developing:

  • An ordinance,
  • Requirements to implement erosion and sediment control best managment practices (BMPs),
  • Requirements to control other waste at the construction site,
  • Procedures for reviewing construction site plans,
  • Procedures to receive and consider information submitted by the public, and
  • Procedures for inspections and enforcement of stormwater requirements at construction sites.

In addition to the stormwater requirements that Phase II MS4s place on construction sites, construction operators may also need to apply for NPDES permit coverage, generally if their project disturbs more than 1 acre and discharges to a waterbody.

Key BMPs and Resources

MS4s addressing the construction minimum measure should focus on the following key BMPs to help them in developing a stormwater construction program.

BMP Fact Sheets

EPA is updating the following fact sheets. You can request a copy or recommend any changes by filling out and submitting the form at the bottom of the NPDES Contact Us webpage.

The fact sheets describe the BMPs and generally provide applicability, implementation, and effectiveness information to help municipal stormwater and construction site operators comply with the stormwater Phase II requirements.
