Comparison: State vs. Federal

Rules. Louisiana has developed effluent discharge regulations that generally follow the federal standards. The state standards are industry-specific and are incorporated into National Pollutant Discharge Elimination System (NPDES) permits (LAC 33:IX.2301 to 33:IX.7129). See the national section EFFLUENT LIMITATIONS and the state section THERMAL DISCHARGES for additional guidance on effluent standards.

Administration and enforcement. DEQ's Office of Environmental Services is responsible for the administration and enforcement of the state's effluent limitations regulations for state discharge permits. See the state section NPDES PERMIT for more information on Louisiana's wastewater discharge permit requirements.
