What is the Nitrogen Reduction Strategy?

EPA is implementing a strategy to aggressively continue progress on nitrogen reductions, in parallel with the States’ continued implementation of the 2000 Total Maximum Daily Load (TMDL), and achieve water quality standards throughout Long Island Sound and its embayments and near shore coastal waters. The strategy recognizes that more work must be done to reduce nitrogen levels, further improve dissolved oxygen (DO) conditions, and address other nutrient-related impacts in Long Island Sound. The nitrogen reduction strategy complements the 2000 TMDL in important ways. Foremost, while the 2000 TMDL is premised on achieving water quality standards for DO in the open waters of LIS, the EPA strategy expands the focus to include other nutrient-related adverse impacts to water quality, such as loss of eelgrass, that affect many of LIS’s embayments and near shore coastal waters.

NEW:  The summary report of an independent technical review for two key deliverables of the Long Island Sound Nitrogen Reduction Strategy  is now posted on the Long Island Sound Study website. The two products reviewed are: Subtask F/G: Summary of Establishing Nitrogen Endpoints for Three Long Island Sound Watershed Groupings, and Subtask E: Summary of the Hydrodynamic Analysis Conducted to Relate Tributary Loads to Areas of Influence and Relative Contributions to Embayments.  Read a description of the purpose and scope of the External Review here. Find the External Review document here.  See below for the subtask memos  in the project deliverables list.

The following documents will help you learn more about the strategy.
