{"abstract":"The Environmental Protection Agency (EPA) is approving a temporary modification of the boundaries of the Massachusetts Bay Dredged Material Disposal Site (MBDS) pursuant to the Marine Protection, Research, and Sanctuaries Act (MPRSA), as amended. The purpose of this temporary site modification is to allow for the environmental restoration of a particular area adjacent to the MBDS (Potential Restoration Area) by temporarily expanding the boundaries of the existing MBDS. The temporary expansion is a circular area that contains the Potential Restoration Area, which includes most of the historic Industrial Waste Site (IWS). Decades ago, the IWS was used for the disposal of barrels containing industrial, chemical and low-level radioactive waste, as well as for the disposal of munitions, ordnance, construction equipment, and contaminated dredged material. The modification of the disposal site boundary will enable the U.S. Army Corps of Engineers (USACE) to place suitable dredged material generated from the Boston Harbor Deep Draft Navigation Project at the Potential Restoration Area in order to cover the barrels and other wastes disposed there in the past. This is expected to improve environmental conditions at the site. The Deep Draft Navigation Project includes improvement dredging of the main ship channel, which will generate approximately 11 million cubic yards (cy) of dredged material. The existing MBDS will continue to be used for disposal of other dredging projects, as usual. The expansion area will permanently close upon completion of the Boston Harbor Deep Draft Navigation Project, while the existing MBDS will remain open for the disposal of other suitable dredged material. Like the MBDS, however, the expansion area will be subject to ongoing monitoring and management to monitor the recovery of the area and to ensure continued protection of the marine environment.","action":"Final rule.","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/2018/05/29/2018-11322.html","cfr_references":[{"chapter":null,"citation_url":null,"part":228,"title":40}],"citation":"83 FR 24408","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date of this rule is June 28, 2018.","disposition_notes":null,"docket_ids":["EPA-R01-OW-2017-0528","FRL-9978-51-Region 1"],"dockets":[],"document_number":"2018-11322","effective_on":"2018-06-28","end_page":24414,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2018/05/29/2018-11322.xml","html_url":"https://www.federalregister.gov/documents/2018/05/29/2018-11322/ocean-disposal-temporary-modification-of-an-ocean-dredged-material-disposal-site-in-massachusetts","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2018-11322?publication_date=2018-05-29","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2018-05-29/2018-11322/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":516,"last_updated":"2026-08-26 02:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2018-05-29/pdf/2018-11322.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2018-11322.pdf?1527252320","publication_date":"2018-05-29","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2018/05/29/2018-11322.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Final signed Environmental Assesment","document_id":"EPA-R01-OW-2017-0528-0015"},{"title":"Draft Environmental Assessment on the Expansion of the Massachusetts Bay Ocean Dredged Material Disposal Site (ODMDS)","document_id":"EPA-R01-OW-2017-0528-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R01-OW-2017-0528","supporting_documents_count":2,"docket_id":"EPA-R01-OW-2017-0528","regulation_id_number":null,"title":"Ocean Disposal; Temporary Modification of an Ocean Dredged Material Disposal Site in Massachusetts Bay","checked_regulationsdotgov_at":"2018-06-18T10:00:15Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":24408,"subtype":null,"title":"Ocean Disposal; Temporary Modification of an Ocean Dredged Material Disposal Site in Massachusetts Bay","toc_doc":"Temporary Modification of an Ocean Dredged Material Disposal Site in Massachusetts Bay","toc_subject":"Ocean Disposals:","topics":["Environmental protection","Water pollution control"],"type":"Rule","volume":83}
