INDUSTRIAL WASTE PERMIT. A permit issued by the village to industrial users for the right to discharge wastewater into the POTW system provided conditions in the permit for monitoring, reporting, and waste strength limitations are met. INDUSTRIAL WASTE PERMITS are valid for a period of five years or subject to change whenever significant changes occur in the discharge from the industrial user as determined by the Superintendent or Pretreatment Coordinator.
INDUSTRIAL WASTES. The wastewater from industrial process, trade, or business as distinct from domestic or sanitary wastes.
INTERFERENCE. A discharge which, along or in conjunction with a discharge or discharges from other sources, both:
(1) Inhibits or disrupts the POTW, its treatment processes or operations, or its sludge processes, use or disposal; and
(2) Therefore is a cause of a violation of any requirement of the POTW’s NPDES permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge use or disposal in compliance with the following statutory provisions and regulations or permits issued thereunder (or more stringent state or local regulations); § 405 of the Clean Water Act being 33 U.S.C. §§ 1251 et seq., the Solid Waste Disposal Act (SWDA) being 42 U.S.C. §§ 6901 et seq.

NEW SOURCE. Any building, structure, facility or installation from which there is or may be a discharge of pollutants, the construction of which commenced after the publication of proposed pretreatment standards under § 307(c) of the Act which will be applicable to such source if such standards are thereafter promulgated in accordance with that section, provided that:
(1) (a) The building, structure, facility or installation is constructed at a site at which no other source is located;
(b) The building, structure, facility or installation totally replaces the processor production equipment that causes the discharge of pollutants at an existing source; or
(c) 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.
(2) 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.
(3) Construction of a new source as defined under this subsection has commenced if the owner or operator has begun, or caused to begin as part of a continuous onsite construction program:
