SUPPLEMENTARY INFORMATION: Back to Top

EPA is proposing to reissue two draft general permits for the discharge of uncontaminated water from construction dewatering intrusion and/or stormwater accumulation from sites that disturb less than one acre of land and short and long term dewatering of foundation sumps. While the draft general permits are two distinct permits, for convenience, EPA has grouped them together in a single document and has provided a single fact sheet for the two draft general permits. This document refers to the draft general “permit” in the singular. The draft general permit, appendices and fact sheet are available at: http://www.epa.gov/region1/npdes/dewatering.html.

The draft General Permit establishes Notice of Intent (NOI) requirements, effluent limitations, standards, prohibitions, and management practices for facilities with construction dewatering of groundwater intrusion and/or storm water accumulation from sites less than one acre and short-term and long-term dewatering of foundation sumps. The draft permit includes effluent limitations based on best professional judgment (BPJ) and water quality considerations. When EPA has not promulgated effluent limitations for a category of discharges, or if an operator discharges a pollutant not covered by an effluent limitation guideline, effluent limitations may be based on the BPJ of the agency or permit writer. The BPJ limits in the general permit are in the form of non-numeric control measures, commonly referred to as best management practices (BMPs). The effluent limits established in the draft permit assures that the surface water quality standards of the receiving water are protected, maintained and/or attained. Discharges that contain pollutants in quantities which represent reasonable potential to cause or contribute to violations of water quality standards will not be granted coverage under this general permit. Those dischargers must either apply for an individual permit or seek coverage under EPA's Remediation General Permit.

The provisions related to the ESA have be updated from the 2008 general permit and new species of concern have been added. EPA has requested concurrence from the appropriate federal services (U.S Fish and Wildlife Service and National Marine Fisheries Service) in connection with this draft permit.
