Sewerage systems; state adoption of federal criteria.

Directs the State Water Control Board (the Board) not to adopt certain U.S. Environmental Protection Agency (EPA) freshwater ammonia water quality criteria (the Criteria) unless the Board includes in such adoption a phased implementation program consistent with the federal Clean Water Act with certain funding and timing considerations. The bill also directs the Department of Environmental Quality to (i) identify any other states that have adopted the Criteria as of July 1, 2018; (ii) identify those procedures for the implementation of the Criteria that will minimize the impact of such implementation on Virginia sewerage systems while complying with the Clean Water Act; and (iii) report its findings to the Chairmen of the Senate Committee on Agriculture, Conservation and Natural Resources, the House Committee on Agriculture, Chesapeake and Natural Resources, the Senate Finance Committee, and the House Appropriations Committee by November 1, 2018.
