The final modifications represent the results of mediation supervised by the U.S. Court of Appeals for the District of Columbia Circuit Mediation Program between EPA and petitioners the National Association of Homebuilders (NAHB), the Home Builders and Remodelers Association of Massachusetts, Inc. (HBRAMA), the New Hampshire Home Builders Association (NHHBA), the Center for Regulatory Reasonableness (CRR), the Massachusetts Coalition for Water Resources Stewardship (MCWRS), the Town of Franklin, Massachusetts, (Franklin), the City of Lowell, Massachusetts (Lowell), the Conservation Law Foundation (CLF), and the Charles River Watershed Association (CRWA). In April 2020, EPA and the petitioners entered into settlement agreements that included commitments for EPA to propose certain modifications to the 2016 Massachusetts Small MS4 General Permit and the 2017 New Hampshire Small MS4 General Permit, and then to take final action on each proposal.","action":"Notice of availability of final permit modifications.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2020/12/16/2020-27637.html","cfr_references":[],"citation":"85 FR 81464","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"These final permit modifications are effective 30 days after signature.
