This committee has several sector based workgroups under it including:

• The Cooling Water Steam Electric Workgroup which serves as a forum for state-to-state and state-EPA discussion of the §316(b) cooling water intake and steam electric effluent limit guidelines.
• The Pretreatment Workgroup which focuses on the pretreatment program and issues associated with pretreatment effluent limitation guideline (ELG) development, implementation, and related policy.
• The Rural Workgroup which works on issues associated with animal agriculture management, pesticide permitting, and logging/forest roads.
• The Stormwater Workgroup’s focus areas includes construction and post construction stormwater programs, industrial stormwater, MS4 program updates, CSO/SSO, green infrastructure, blending, integrated planning, and other issues impacting municipal facilities.

Members of this Committee also represent ACWA and their state on a number of EPA workgroups associated with the State Review Framework, NPDES eReporting Rule Implementation, New Enforcement Framework, and several other initiatives under the Office of Compliance and Enforcement.
