Definitions of Terms 44 45 The applicable definitions set forth in 40 CFR 122, 123, 124, 125, 144, 146, 403 and 503 and all 46 amendments and additions thereto are incorporated herein and adopted by reference and shall be 7 1 considered valid in this regulation, unless a term is otherwise defined herein. In addition, the 2 following definitions are applicable. 3 4 (1) "Affected Discharger" is an existing permitted wastewater discharger, or a 5 proposed wastewater discharger, which has either a pending permit application or 6 a permit or is included in a State Revolving Fund ("SRF") Facilities Plan. 7 8 (2) "Allowable Loading" or "available assimilative capacity" is that portion of the 9 loading capacity of a water body that is available for allocating to a point source 10 discharger(s) through regulation by the Department. It is the difference between 11 the loading capacity and the total loading of pollutants from other sources, such as 12 background, nonpoint sources, and exempt sources. 13 14 (3) "Ambient water quality" means the physical, chemical and biological 15 characteristics of waters of the State. 16 17 (4) "Applicant" means a person applying to the Permit Board for an individual State 18 permit, coverage under a State general permit, UIC permit, individual NPDES 19 permit or coverage under an NPDES general permit to discharge wastes or other 20 fluids into the waters of the State, or to operate a treatment works.
