The Maryland Department of Environment has proposed onsite regulations to require nitrogen removal technology for new systems located on land that drains to the Chesapeake Bay, Atlantic coastal bays or other impaired waters. The proposed regulations also set minimum operation and maintenance requirements for the life of the equipment. Companies that install or maintain the equipment must complete a state course and be certified by the manufacturer. Existing systems that fail could still be replaced with conventional systems under the proposal.
