​WQT Register

The WQT Register provides a ledger of certified credits and their current status. This ledger also shows where trades have occurred and who is involved. To have your credits certified and posted on the Register, please foll​ow the instructions here. 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.

WQT Market Board

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.
