      NEW SOURCE.
         (a)   Any building, structure, facility, or installation from which there may be a discharge of pollutants, the construction of which commenced after the publication of proposed categorical pretreatment standards under § 307(c) of the Act which will be applicable to such source if such standards are thereafter promulgated in accordance with § 307(c), provided that:
            1.   The building, structure, facility, or installation is constructed at a site at which no other source is located; or
            2.   The building, structure, facility, or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
            3.   The production or wastewater generating processes of the building, structure, facility, or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source, should be considered.
         (b)   Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation meeting the criteria of division (a)1. or (a)2. above but otherwise alters, replaces, or adds to existing process or production equipment.
         (c)   For purposes of this definition, construction of a new source has commenced if the owner or operator has:
            1.   Begun, or caused to begin as part of a continuous on-site construction program:
               A.   Any placement, assembly, or installation of facilities or equipment; or

            2.   Entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility, engineering, and design studies do not constitute a contractual obligation under this definition.

      PASS-THROUGH. A discharge which exits the Control Authority's (and/or POTW's if different from the Control Authority) into waters of the state in quantities or concentrations which, alone or with discharges from other sources, causes a violation of the POTW's NPDES, non-discharge permit, or collection system permit.
      PERSON.

This definition includes any devices or systems used in the collection, storage, treatment, recycling, and reclamation of municipal sewage or industrial wastes of a liquid nature. It also includes sewers, pipes, and other conveyances only if they convey wastewater to the POTW treatment plant. For the purposes of this chapter, POTW shall also include any sewers that convey wastewaters to the POTW from persons outside the town who are, by contract or agreement with the town, or in any other way, users of the town's POTW.
      POTW TREATMENT PLANT. That portion of the POTW designed to provide treatment to wastewater.
      PRETREATMENT or TREATMENT. The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing such pollutants into a POTW. The reduction or alteration can be obtained by physical, chemical or biological processes, or process changes or other means, except by diluting the concentration of the pollutants, unless allowed by an applicable pretreatment standard.
      PRETREATMENT PROGRAM. The program for the control of pollutants introduced into the POTW from non-domestic sources which was developed by the town in compliance with 40 CFR 403.8 and approved by the approval authority as authorized by G.S. § 143-215.3(a)(14) in accordance with 40 CFR 403.11.
