(A) Purpose; policy.
(1) This chapter sets forth uniform requirements for users of the publicly owned treatment works for the City of Washington (Washington) and enables Washington to comply with all applicable state and federal laws, including the Clean Water Act (33 U.S.C. §§ 1251 et seq.) and the General Pretreatment Regulations (40 Code of Federal Regulations Part 403). The objectives of this chapter are:
(a) To prevent the introduction of pollutants into the publicly owned treatment works that will interfere with its operation;
(b) To prevent the introduction of pollutants into the publicly owned treatment works that will pass through the publicly owned treatment works, inadequately treated, into receiving waters, or otherwise be incompatible with the publicly owned treatment works;
(c) To protect both publicly owned treatment works personnel who may be affected by wastewater and sludge in the course of their job and duties and the general public;
(d) To promote reuse and recycling of industrial wastewater and sludge from the publicly owned treatment works;
(e) To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the publicly owned treatment works;
(f) To enable the City of Washington to comply with its National Pollutant Discharge Elimination System permit conditions, sludge use and disposal requirements, and any other federal or state laws to which the publicly owned treatment works is subject; and
(g) To accept or deny any new or increased discharges from any indirect discharger.
(2) This chapter shall apply to all users of the publicly owned treatment works. This chapter authorizes the issuance of wastewater discharge permits approved by IDEM; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the selling of fees for the equitable distribution of costs resulting from the program established herein.
(B) Administration. Except as otherwise provided herein, the Wastewater Superintendent (the Superintendent) shall administer, implement, and enforce the provisions of this chapter. Any powers granted to or duties imposed upon the Wastewater Superintendent may be delegated by the Wastewater Superintendent to other Wastewater Treatment Facilities personnel.

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 (a)2. or 3. above but otherwise alters, replaces, or adds to existing process or production equipment.

1. Begun, or caused to begin, as part of a continuous on-site construction program (i) any placement, assembly, or installation of facilities or equipment; or (ii) significant site preparation work including clearing, excavation, or removal of existing buildings, structures, or facilities which is necessary for the placement, assembly, or installation of new source facilities or equipment.
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.

PRETREATMENT. 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, introducing such pollutants into the POTW. This reduction or alteration can be obtained by physical, chemical, or biological processes; by process changes; or by other means, except by diluting the concentration of the pollutants unless allowed by an applicable pretreatment standard.
