Nutrient Credit Registry

Trying to find credits?
If your facility is in need of credits to meet permit cap load requirements, what credits are available and who has them are found in the 2017 Verified Nitrogen Credits (PDF) and 2017 Verified Phosphorus Credits (PDF) lists. These lists are updated daily when changes occur.

OVERVIEW

The Department of Environmental Protection (DEP) maintains a registry with information on credit certification, verified credits, and credits that are registered as sold. The program is based on a Compliance Year (CY) that runs from October 1st to September 30th. Detailed information concerning the number of certified, verified, and registered credits is listed below.

Wastewater Treatment Plants that are buying and/or selling credits should use the current Annual Chesapeake Bay Excel spreadsheet (XLSM) (Annual Nutrient Monitoring) to ensure accurate accounting.


Certification

Certification means approval has been given by DEP for a pollutant reduction activity to generate credits. The approved credit generator may or may not generate credits during a compliance year. Generated credits must be verified by DEP before they may be sold and registered to an NPDES permit.

  • Certified Generator Certification IDs (PDF)
    This is a list of the certification ID numbers for all currently certified generators. Point sources are only assigned Certification IDs when they verify credits. If you are a point source verifying credits for the first time, please contact the program at RA-EPPANUTRIENTTRAD@pa.gov to be assigned a certification ID.

POINT SOURCES (PS)

All NPDES-permitted Significant Sewage Point Source discharges within the Chesapeake Bay Watershed with cap loads and listed in the Point Source Credit Generators Table (PDF) that meet credit generation requirements (see Credit Generation Process) have the potential to generate credits under a mass certification. However, not all PS generate credits in a compliance year.

NONPOINT SOURCES (NPS)

  • NPS Nutrient Credit Generators (PDF)
    A list of all currently certified NPS credit generators that have the potential to generate credits. The list will be updated periodically.

Verification

Verification means approval has been given by DEP that a generator has used their approved verification plan to demonstrate that a pollutant reduction activity generated credits during the compliance year. Verified credits may be sold and registered to an NPDES permit.
