A. Facility's Requirements: A user discharging or with potential to discharge any waste into the POTW as set forth in section 8-3-10, 8-3-11 or 8-3-12 of this chapter 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:
2. Control the quantities and rates of discharge of such wastewater.
3. Reduce the pollutants to such concentration and flows as may be contained in the user's wastewater discharge permit.
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. Review And Approval Of Plans: 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, chapters 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 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 initiation of the changes.
C. Maintenance Of Facilities: Users shall continuously maintain all pretreatment facilities required by this chapter in satisfactory and effective operating condition at the sole expense of such user.
D. Special Agreements: 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 such user; provided, however, that such agreement shall have the prior approval of the WRA Board, shall not conflict with the Iowa Department of Natural Resources and U.S. Environmental Protection Agency requirements, and shall be consistent with subsection 8-3-11B and sections 8-3-12 and 8-3-13 of this chapter, and subsection F of this section.
E. Rejection Of Waste: The WRA Director may reject any waste which, in the opinion of the Director, may cause interference or pass-through.
F. Waste Discharge Approval Required: 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 subsection 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 such spill. Pretreatment waste is prohibited from disposal to the waters of the State except as specifically permitted by the Iowa Department of Natural Resources. (Ord. 1069, 3-14-2019)
