The WQT Registry provides a ledger of certified credits and their current trading status. This ledger also shows where trades have occurred and who is involved. If you are a NPDES permittee looking to use credits to meet a permit requirement, please contact your permit issuer to confirm that the credits you are purchasing can be used to meet permit requirements.
Below are the low, middle, and high averages per pound of nitrogen (N), phosphorus (P), and sediment (S). These averages include purchasing credits from wastewater treatment plants (N, P, S) as well as oyster aquaculture (N and P only). The averages also include Clean Water Commerce Act purchasing numbers as well as our Maryland Water Quality Trading market pricing.

The WQT Market Board is a place for those interested in buying and selling WQT credits. Users can list the watershed, the vintage (year), and other information pertaining to the credits they are looking to buy or sell. If you would like to post information to the WQT Market Board, please contact the WQT Program: mde.wqtrading@maryland.gov. Please note that the information on the WQT Market Board is not certified or endorsed by MDE or MDA. The list of credits certfied by MDE is only available on the WQT Register.
