EPA Construction General Permit

OVERVIEW

Construction activities (including other land-disturbing activities) that disturb one acre or more are regulated under the NPDES stormwater program. On March 10, 2003, new regulations came into effect that extended coverage to construction sites that disturb one to five acres in size, including smaller sites that are part of a larger common plan of development or sale. Sites disturbing five acres or more were regulated previously.

Operators of regulated construction sites are required to develop and implement stormwater pollution prevention plans and to obtain permit coverage from an authorized state or from EPA, if the state is not authorized by EPA to issue NPDES permits.

Most states are authorized to implement the NPDES permit program, including the stormwater program. Use this list to determine if your state operates the NPDES stormwater program. Please contact your permitting authority to determine the specific requirements that apply to you.

Where EPA is the permitting authority, the Construction General Permit (CGP) outlines a set of provisions construction operators must follow to comply with the requirements of the NPDES stormwater regulations. The CGP covers any site one acre and above, including smaller sites that are part of a larger common plan of development or sale, and replaces and updates previous EPA permits. (Note: Construction activities in EPA Region 4 are covered by a separate construction permit. See this list for details.)

Permittees may contact the NOI Processing Center via on-line form or at (866) 352-7755 for questions about filing by mail.
