Maryland Board of On-Site Wastewater Professionals


During the 2022 legislation, the Maryland General Assembly passed legislation establishing the
State Board of On-Site Wastewater Professionals (the Board) within the Department with a
provision that until the new licensing requirements are established by the Board, an individual who
provides on-site wastewater services in the State may only continue to do so if they pay a $150 fee to
the Department on or before December 31, 2022 and every two years thereafter until the Board and
MDE develop full licensing requirements. Please see the links below to the MDE letter which answers some frequently asked questions regarding this and the application to MDE that will need to be turned in. Please note, that as more information is released that MOWPA will pass it along to our members. If you have any questions, we will do our best to answer them or find out who can help.
