      NEW SOURCE.
         (a)   Any building, structure, facility, or installation from which there is or may be the discharge of pollutants, the construction of which is commenced after the publication of proposed pretreatment standards under § 307(c) of the Act (33 U.S.C. § 1347) which will be applicable to such source if such standards are thereafter promulgated in accordance with that section, provided that:
            1.   The building, structure, facility, or installation is constructed at the site at which no other source is located;
            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 divisions (1)(b) or (1)(c) of this definition but otherwise alters, replaces, or adds to existing process or production equipment.
         (c)   Construction of a NEW SOURCE as defined under this section has commenced if the owner operator has:
            1.   Begun or caused to begin as part of a continuous on-site construction program:

            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.
      OWNER. The Carroll County Department of Public Works.
      PASS-THROUGH. A discharge which exits the POTW into waters of the United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of violation of any requirement of the POTW’s NPDES permit (including an increase in the magnitude or duration of violation).

      SEVERE PROPERTY DAMAGE. Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. SEVERE PROPERTY DAMAGE does not mean economic loss caused by delays in production.
      SIGNIFICANT INDUSTRIAL USER.
         (a)   Any industrial user who:
            1.   Is subject to national categorical standards;
            2.   Has a discharge of 25,000 gallons or more per average work day;

         (b)   Upon the finding that an industrial user meeting the above criteria of this definition has no reasonable potential for adversely affecting the POTW’s operation or for violating any pretreatment standard or requirement, the county may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with 40 C.F.R. § 403.8(f)(6), determine that such industrial user is not a SIGNIFICANT INDUSTRIAL USER. This division (b) does not apply to categorical industries.
