Stormwater Local Assistance Fund; grants to non-MS4 localities.

Authorizes the Department of Environmental Quality (the Department), with the approval of the Secretary of Natural Resources, to designate a portion of the moneys appropriated to the Stormwater Local Assistance Fund for fiscal year 2020 and any subsequent fiscal year, in an amount no greater than 20 percent of the appropriated amount, to provide matching grants to local governments that are not regulated under municipal separate storm sewer system (MS4) permits for the planning, design, and implementation of stormwater best management practices. The bill directs the Department to prioritize grants for projects that are regional in scope. The bill requires any designated moneys remaining after the Department has completed its annual solicitation of grant applications and made related authorization decisions for projects proposed by non-MS4 localities to be available for authorization by the Department to additional projects of MS4 localities. The bill directs the Department to seek stakeholder input and public comment in developing eligibility criteria and to submit such criteria by January 1, 2020, for consideration by the State Water Control Board.
