Riepilogo

The Regional Administrator of Region I is issuing final National Pollutant Discharge Elimination System (NPDES) general permits for non-contact cooling water discharges to certain waters of the States of Maine, Massachusetts, and New Hampshire. These general NPDES permits establish notice of intent (NOI) requirements, effluent limitations, standards, prohibitions and management practices for facilities with discharges authorized by the permit. Owners and/or operators of facilities discharging non-contact cooling water will be required to submit to EPA, Region I, a notice of intent to be covered by the appropriate general permit within 180 days of the effective date of this permit and will receive a written notification from EPA of permit coverage and authorization to discharge under one of the general permits.
