Users subject to National Categorical Pretreatment Standards (NCPS) as contained in 40 CFR I, Subchapter N, Part 405-471 shall comply with the standards and applicable reporting requirements under 40 CFR 403.12. New sources of categorical discharge shall meet National Categorical Pretreatment Standards in the shortest feasible time, but in no case longer than 90 days from the commencement of discharge. Failure to comply shall be a violation of this chapter and subject the user to enforcement action. The WRA is required to notify all known affected categorical users of the applicable reporting requirements under 40 CFR 403.12. Failure of the WRA to notify a user shall not relieve the user of the duty, if any, to comply with National Categorical Pretreatment Standards.
The City, acting at the direction of the WRA, reserves the right to establish more stringent limitations or requirements on discharges to the POTW than those contained in this chapter if deemed necessary to comply with the purpose and policy objectives presented in Section 100.05 of this chapter.
1. A user discharging or with potential to discharge any waste into the POTW as set forth in Section 100.11, 100.12 or 100.13 of this division 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:
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, 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 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 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 100.66(2) and Sections 100.13 and 100.14 of this chapter, and Subsection 6 of this section.
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 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 water of the state except as specifically permitted by the Iowa Department of Natural Resources.
