Comparison: State vs. Federal

Rules. The state is fully authorized by EPA to administer the National Pollutant Discharge Elimination System (NPDES) pretreatment program. Virginia's pretreatment regulations are identical to the federal regulations with the exception of the program implementation time frame.

Administration and enforcement. DEQ is responsible for administering the Virginia pretreatment program and has authority to enforce its requirements. DEQ serves as the approval authority for publicly owned treatment work (POTWs) and the control authority for the rest of the state.
