Integrated Lists & Other Reports
Proposed Massachusetts Year 2012 Integrated List of Waters (CWA Sections 303d and 305b) The Proposed Massachusetts Year 2012 Integrated List of Waters is provided here for public review and comment. This document will be submitted to the United States Environmental Protection Agency (EPA) in fulfillment of reporting requirements of both s. 305(b) and s. 303(d) of the Clean Water Act. In addition to the actual proposed listing of the individual categories of waters, the report presents a brief history of water quality management in Massachusetts and presents a brief overview of the methodology that is currently employed for assessing and reporting on the status of Massachusetts waters. The 2012 List is based primarily on new watershed assessments completed for the Blackstone, Boston Harbor (including Mystic, Neponset and Weymouth/Weir), Merrimack and Parker watersheds and the Cape Cod coastal drainage areas. Water quality assessments of these watersheds have been completed and can be found at http://www.mass.gov/dep/water/resources/wqassess.htm. Final Massachusetts Year 2010 Integrated List of Waters (CWA Sections 303d and 305b) The Federal Clean Water Act requires MassDEP to submit to US EPA a listing of waterbodies in the state that are not expected to meet the surface water quality standards set forth in the Act and will require the development of a TMDL. This list was approved by the US EPA on November 16, 2011. Final Massachusetts Year 2008 Integrated List of Waters (CWA Sections 303d and 305b) The Federal Clean Water Act requires MassDEP to submit to US EPA a listing of waterbodies in the state that are not expected to meet the surface water quality standards set forth in the Act and will require the development of a TMDL. This list was approved by the US EPA on May 4, 2009. MassDEP POTW Nitrogen Evaluation This report evaluates 21 publicly-owned wastewater treatment plants (POTWs) located in the Blackstone, Ten Mile, Connecticut, Chicopee, Millers, Westfield, and Deerfield Watersheds for their ability to remove nitrogen to several discharge levels and provides "order of magnitude" costs associated with achieving those levels. Note: Some of these files will take some time to download based on connection speed. This report is also available as a CD-Rom and can be obtained by contacting your regional office to request a copy.

Water, Wastewater & Wetlands: Total Maximum Daily Loads (TMDLs)
Multi-State
Final Northeast Regional Mercury TMDL - October 2007 The Northeast Regional Mercury TMDL is a Federal Clean Water Act mandated document that identifies pollutant load reductions necessary for regional waterbodies to meet and maintain compliance with state and federal water quality standards and was prepared by the New England Interstate Water Pollution Control Commission (NEIWPCC) in cooperation with the states of Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont. The TMDL covers waterbodies that are impaired primarily due to atmospheric deposition of mercury.
