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.
