stormwater-drainCT DEEP Releases Revised Draft MS4 Permit

The Connecticut Department of Environmental Protection (CT DEEP) has released a modified draft version of their Municipal Separate Storm Sewer System (MS4) General Permit.

The modified version of the permit language moderates some of the previously proposed requirements while expanding others. While the details of the new permit are being finalized, the current MS4 General Permit has been extended to January 8, 2016 and is still in effect. Permittees must continue to implement their Stormwater Management Plan, conduct annual sampling, and submit annual reports.

Learn more about the proposed changes. Contact Matt Ladewig at 401.330.1204 with questions.

As of February 4, 2015, The New England District of the U.S. Army Corps of Engineers (USACE) announced the issuance of the Massachusetts General Permits (GPs) for activities in Corps jurisdiction under Section 404 of the Clean Water Act; Section 10 of the Rivers and Harbors Act of 1899; and Section 103 of the Marine Protection, Research, and Sanctuaries Act.

CLF & CRWA Take Action Against Non-Enforcement of Stormwater Controls in Massachusetts & Rhode Island

The Conservation Law Foundation (CLF) and Charles River Watershed Association (CRWA) have released a notice of intent to sue the US Environmental Protection Agency for non-enforcement of stormwater controls under the citizen enforcement provision (Section 505) of the Clean Water Act. In one of the affected areas, Charles River Watershed in Massachusetts, CLF and CRWA claim that commercial, industrial, institutional, and high-density residential stormwater dischargers have not been notified by the EPA that they must obtain Clean Water Act Discharge Permits. The notice also claims that there has been a failure by the EPA to make a final determination within 90 days on CLF's previous "Petition for Designation of Certain Stormwater Discharges into the Charles River". CLF also released a notice of intent to sue the EPA for non-enforcement of similar stormwater controls in areas of Rhode Island, including Mashapaug Pond, Spectacle Pond, and Aquidneck Island.
