As used in sections 22a-522 to 22a-525, inclusive:
(1) “Equivalency factor” means a ratio of the unit response of dissolved oxygen to nitrogen in Long Island Sound for each publicly-owned treatment works based on the geographic location of the specific publicly-owned treatment works' discharge point divided by the unit response of the geographic area with the highest impact;
(2) “Equivalent nitrogen credit” means a nitrogen credit multiplied by the equivalency factor;
(3) “Equivalent pounds” means the actual pounds of nitrogen discharged by a publicly-owned treatment works multiplied by the equivalency factor for that publicly-owned treatment works;
(4) “Individual waste load allocation” means that portion of the state-wide waste load allocation apportioned to an individual publicly-owned treatment works;
(5) “Nitrogen” means the total of ammonia nitrogen, organic nitrogen, nitrite nitrogen and nitrate nitrogen;
(6) “Nitrogen Credit Advisory Board” means the board appointed by the Commissioner of Energy and Environmental Protection pursuant to section 22a-523;
(7) “Nitrogen credit exchange program” means the program within the Department of Energy and Environmental Protection established pursuant to section 22a-524;
(8) “Nitrogen credit” means the difference between the annual total nitrogen load specified for a publicly-owned treatment works in the general permit for nitrogen discharges and the annual total nitrogen load discharged by that publicly-owned treatment works expressed as pounds of nitrogen per day;
(9) “Nonpoint source” means any source of nitrogen originating from other than a readily discernible end of pipe source;
(10) “Publicly-owned treatment works” means a system used for the collection, treatment or disposal of sewage from one or more parcels of land and that discharges to the waters of the state and is owned by a municipality or the state;
(11) “State-owned equivalent nitrogen credits” means the difference between the annual state-wide waste load allocation established in the total maximum daily load and the sum of the annual discharges for all publicly-owned treatment works;
(12) “State-wide waste load allocation” means the maximum allowable nitrogen load from publicly-owned treatment works into Long Island Sound that will meet water quality standards as specified in the total maximum daily load;
(13) “Total maximum daily load” means the total maximum daily load analysis to achieve water quality standards for dissolved oxygen in Long Island Sound, as established by the Department of Energy and Environmental Protection and as approved by the United States Environmental Protection Agency; and
(14) “Unit response” means the reaction of dissolved oxygen in Long Island Sound to a change in nitrogen loading of 1.0 pound.
