Federal CGP: Appendices & Modifications Program Overview

EPA finalized a modification to the NPDES 2017 Construction General Permit (CGP), which covers eligible stormwater discharges from construction activities in areas where the EPA is the permitting authority. The final modified permit takes effect on June 27, 2019.

After EPA issued the original 2017 CGP in January 2017, both the National Association of Home Builders and the Chesapeake Bay Foundation filed petitions for review in the D.C. Circuit. Based on new information provided to EPA, the Agency proposed a permit modification on December 12, 2018, for a 45-day comment period to clarify the intent of certain permit requirements.

The final modification, which is substantially similar to the proposal, removes examples of the types of parties that could be considered operators in the definition of operator; aligns three requirements that implement the Construction and Development Effluent Limitations Guidelines (ELG) and New Source Performance Standards (NSPS) with the ELG text; and clarifies individual operator responsibilities in multiple operator scenarios.

The final modified 2017 CGP replaces the original 2017 CGP, but does not affect the eligible coverage area; the number or type of entities eligible to be covered by the permit; nor the five-year permit term of the original 2017 CGP, meaning the modified 2017 CGP will still expire on February 16, 2022. This modification does not affect state-issued CGPs.

Intended Audience

  • Non-regulatory 3rd Party Inspectors
  • Civil Consultants/Students
  • Environmental Consultants/Students

A note for current CGP permittees: This final modification does not affect permit coverage, therefore no action is required of existing operators regarding your authorization to discharge under the CGP. If you were covered under the 2017 CGP, you will still be covered under the modified permit.

The EPA website provides additional information on the NPDES Stormwater Program (Construction Activities) webpage:

   • Stormwater runoff is generated from rain and snowmelt events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground.

   • The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters.

   • To protect these resources, communities, construction companies, industries, and others, use stormwater controls, also known as Best Management Practices (BMPs).

   • These BMPs filter out pollutants and/or prevent pollution by controlling it at its source.
