Nitrogen Coordination Work Group

Purpose

The Nitrogen Coordination Work Group is an opportunity for staff from the Connecticut Department of Energy and Environmental Protection and New York State Department of Environmental Conservation with support from LISS partners to coordinate ongoing nitrogen reduction efforts in the Long Island Sound Study area.

EPA Nitrogen Strategy Subtask Memos and Supporting Documents (Updated 12/20/22):

Project Map: a Study Area map of all watersheds evaluated in this memo.

Literature Review Memo: Summary of available information concerning potential assessment endpoints and work conducted
Subtask A: Data summary of individual nitrogen loads for 23 embayments, the Eastern Narrows, the Western Narrows, and Western LIS (Eastern Narrows and Western Narrows combined)
Subtask B: Data summary of regulated point source discharges to LIS
Subtask C: Data summary of tributary loadings to LIS, specifically the Connecticut, Housatonic, and Thames rivers
Subtask D: Summary of existing water quality data collected and analyzed for 23 embayments; the Eastern Narrows; the Western Narrows; the Connecticut, Housatonic, and Thames rivers; and other water quality monitoring stations used for the analysis (includes additional embayments and open water)
Subtask E: Summary of the hydrodynamic analysis conducted to relate tributary loads to areas of influence and relative contributions to embayments. Also, Response to Independent Technical Review of Subtask E
Subtasks F/G: Summary of establishing nitrogen endpoints for three Long Island Sound watershed groupings. Also, Response to Independent Technical Review and Public Comments of Subtasks F/G
Subtask H: Translation of nitrogen target concentrations, as documented in the subtasks F and G memos, into percent reduction target for watershed loads to each embayment waterbody within Long Island Sound
Public Expert and External Technical Review Summary: Summary report of an independent technical review for Subtask E and Subtasks F/G
