Comparison: State vs. Federal

Rules. Connecticut generally follows the federal pretreatment standards. The state has been authorized to administer the National Pollutant Discharge Elimination System (NPDES) pretreatment program. However, Connecticut has established some categorical pretreatment standards that are more stringent than the federal requirements. See the national section PRETREATMENT STANDARDS for a discussion of the federal pretreatment rules.

In addition, the state's prohibited discharge standards include prohibiting discharges which interfere or may have an adverse effect on a publicly owned treatment works' (POTW) sludge handling, use, or disposal. These are specifically related, but not limited to, noncompliance with Section 405 CWA, the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, the Marine Protection Act, or any local or state laws, regulations, or ordinances.

Administration and enforcement. The DEEP's Bureau of Water Protection and Land Use administers and enforces pretreatment standards for wastewater discharges to POTWs in Connecticut.
