  1. CONNECTICUT DEPARTMENT OF ENVIRONMENTAL PROTECTION Connecticut's Nitrogen Trading Program To achieve the TMDL for Long Island Sound

  2. Initial TMDL Allocations2000 Starting Point The initial loading to Long Island Sound from all municipal facilities combined was established in the draft TMDL at: 48,709 lbs/day

  3. Final TMDL Allocations2014 Ending Point The TMDL requires the loading to Long Island Sound from all municipal facilities combined be reduced to: 17,774 lbs/day

  7. Traditional NPDES Implementation: • Your Pipe • High Compliance Cost • Your Permit • High Non-Compliance Cost • Your Problem • Rewards The Last Difficult to Implement

  8. Alternative Trading Implementation: • Our Pipe • Lower Compliance Cost • Our Permit • Lower Non-Compliance Cost • Our Problem • Rewards The First Incentive to Provide Treatment

  11. Public Act 01-180 An Act Concerning Nitrogen Reduction In Long Island Sound • Authority to Issue a General Permit • Establish a Nitrogen Credit Advisory Board • Provides for an Alternate Compliance Program

  12. General Permit for Nitrogen Discharges • Places all POTWs in Connecticut under one nitrogen bubble • Provides total nitrogen effluent limits over 15 years • Allows for a alternate compliance schedule

  13. Establish a Nitrogen Credit Advisory Boardand a Credit Exchange Program to assist in implementation of the TMDL • Provides for a board of 12 members to establish the value of Nitrogen Credits • Board will assist in setting the compliance schedule (annual effluent limits) • Establishes an equivalency factor for each POTW • Purchases and sells all available credits • Establishes a technical assistance program
