1. A user discharging, or with potential to discharge, any waste into the POTW as set forth in Sections 100.08, 100.09, or 100.10 shall be required by the WRA Director to construct, install and operate, at the user's sole expense, such pretreatment facilities as may be required in order to:
A. Reduce the objectionable characteristics or constituents to within the maximum limits provided for in Sections 100.08, 100.09, 100.10 and 100.11;
B. Control the quantities and rates of discharge of such wastewater;
C. Reduce the pollutants to such concentration and flows as may be contained in the user’s wastewater discharge permit;
D. Prevent the discharge of liquid waste containing FOG, sand in excessive amounts, any flammable waste, or other harmful pollutants. All traps or similar devices shall be of a type and capacity needed to perform effectively and shall be readily and easily accessible for cleaning and inspection. All traps or devices shall be provided and maintained in efficient operating condition at all times. Materials removed from traps shall be considered unacceptable for disposal at the WRF unless specifically approved by the WRA Director.
2. All plans, specifications, technical operating data and other information pertinent to the proposed operation and maintenance of pretreatment facilities shall be reviewed and approved by the WRA Director prior to construction. Design and installation of such facilities shall be subject to the requirements of all applicable codes, ordinances and laws, including local zoning regulations. The review and approval of such plans and operating procedures shall, in no way, relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the WRA Director under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operations shall be reported to and be acceptable to the WRA Director prior to the user's initiations of the changes.
3. Users shall continuously maintain all pretreatment facilities required by this chapter in satisfactory and effective operating condition at the sole expense of such user.
4. No provision contained in this chapter shall be construed to prevent or prohibit a separate or special agreement between the WRA and any user whereby wastewater containing waste of unusual strength, character or composition may be accepted for treatment, subject to additional payment by such user; provided, however, that such agreement shall have the prior approval of the WRA Board, shall not conflict with IDNR and U.S. EPA requirements, and shall be consistent with Sections 100.09(2), 100.10, 100.11 and 100.12(6) of this chapter.
5. The WRA Director may reject any waste which, in the opinion of the Director, may cause interference or pass through.
6. Users shall obtain the specific approval of the WRA Director prior to discharging any waste resulting from a pretreatment facility to the POTW. The Director may develop a documentation system to track the transportation and final disposition of any pretreatment waste. Pretreatment waste regulated by this section shall include waste generated as a result of pretreatment processes used to comply with NPDES permits, air pollution permits, wastewater discharge permits, soil/groundwater reclamation processes, and pollutants resulting from a spill of any liquid or solid material or the cleanup of any such spill. Pretreatment waste is prohibited from disposal to the water of the State except as specifically permitted by IDNR.
