(2) Control the quantities and rates of discharge of wastewater;
(3) Reduce the pollutants to those concentration and flows as may be contained in the user's wastewater discharge permit; and
(4) 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.
(B) 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 these facilities shall be subject to the requirements of all applicable codes, chapters and laws, including local zoning regulations. The review and approval of the 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 this subchapter. 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.
(C) Users shall continuously maintain all pretreatment facilities required by this subchapter in satisfactory and effective operating condition at the sole expense of the user.
(D) No section 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 the user; provided, however, that the agreement shall have the prior approval of the WRA Board, shall not conflict with the State Department of Natural Resources and United States Environmental Protection Agency requirements, and shall be consistent with §§ 52.011(B), 52.012, 52.013 and division (F) below.
(E) The WRA Director may reject any waste, which, in the opinion of the Director, may cause interference or pass through.
(F) Users shall obtain the specific approval of the WRA Director prior to discharging any waste resulting from a pretreatment facility to the POTW. The WRA Director may develop a documentation system to track the transportation and final disposition of any pretreatment waste. Pretreatment waste regulated by this division (F) shall include waste generated as a result of pretreatment processes used to comply with national pollutant discharge elimination system 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 spill. Pretreatment waste is prohibited from disposal to the water of the state except as specifically permitted by the State Department of Natural Resources.
