Nutrient Credit Reports

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 must use the current Annual Chesapeake Bay Excel spreadsheet (Excel) (Annual Nutrient Monitoring) to ensure accurate accounting.


Credit 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.

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.

  • PS Nutrient Credit Generators (PDF)
    A list of PS which verified credits in CY 2017. All PS have the potential to generate credits, but this list is intended to assist buyers with identifying the more likely potential sources of credits and how many credit they verified in the previous 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.

Credit 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.

The following links contain information on which credit generators may have verified credits for sale.
