Northeast Regional Mercury TMDL

The Northeast Regional Mercury TMDL is the 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. The Northeast states have a number of statewide, regional, and waterbody-specific fish consumption advisories as a result of mercury pollution and the overall objective of the TMDL is to reduce mercury in regional waterbodies to the point that fish consumption advisories will no longer be necessary. The TMDL was prepared by the New England Interstate Water Pollution Control Commission (NEIWPCC) in cooperation with the state environmental agencies of New York, Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.

The Northeast Regional Mercury TMDL (PDF) (790 KB) was approved by the US Environmental Protection Agency in December 2007.
