The Plant Manager may modify an individual Wastewater Discharge Permit for good cause, including, but not limited to, the following reasons:
(a) The Plant Manager reserves the right to amend any Wastewater Discharge Permit issued hereunder in order to assure compliance by the City with applicable laws and regulations. Within nine months of the promulgation of a National Categorical Pretreatment Standard, the Wastewater Discharge Permit of each discharger subject to such standards shall be revised to require compliance with such standards within the time frame prescribed by such standards. All National Categorical Pretreatment Standards adopted after the promulgation of this chapter shall be adopted by the City as a part of this chapter. Where a discharger, subject to a National Categorical Pretreatment Standard, has not previously submitted an application for a Wastewater Discharge Permit as required, the discharger shall apply for a Wastewater Discharge Permit from the Safety-Service Director within 180 days after the promulgation of the applicable National Categorical Pretreatment Standard by the U.S. Environmental Protection Agency. In addition, the discharger with an existing Wastewater Discharge Permit shall submit to the Plant Manager within 180 days after the promulgation of an applicable National Categorical Pretreatment Standard, the disclosure information required. The discharger shall be informed of any proposed changes in his permit at least thirty days prior to the effective date of change. Any changes or new conditions in the permit shall include a reasonable time schedule for compliance.
(b) The Plant Manager may change production based-categorical pretreatment standards to equivalent concentration limits to facilitate compliance evaluation. These equivalent limits shall be deemed Pretreatment Standards. Industrial Users will be required to comply with the equivalent limitations in lieu of the promulgated categorical standards from which the equivalent limits were derived.
(c) Any Industrial User operating under a control mechanism incorporating equivalent mass or concentration limits calculated from a production-based standard shall notify the Plant Manager within two business days after the User has a reasonable basis to know that the production level will significantly change within the next calendar month. Any User not notifying the Plant Manager of such anticipated change will be required to meet the mass or concentration limits in it control mechanism that were based on the original estimated of the long-term average production rate.
(d) Any Industrial User subject to equivalent mass or concentration limits established by the Manager must include a reasonable measure of the User's long-term production rate in its periodic compliance report.
(e) A change in the POTW that requires either a temporary or permanent reduction or elimination of the authorized discharge.
(f) Information indicating that the permitted discharge poses a threat to the City’s POTW, personnel, receiving waters, or affects the beneficial use of the plant’s biosolids.
(g) Violation of any terms or conditions of the individual wastewater discharge permit.
(h) Misrepresentations or failure to fully disclose all relevant facts in the wastewater discharge permit application or in any required reporting.
(i) Revision or a grant of variance from categorical Pretreatment Standards pursuant to 40 CFR 403.13.
(j) To correct typographical or other errors in the individual wastewater discharge permit.
(k) To reflect a transfer of the facility ownership or operation to a new owner or operator where requested in accordance with Section 925.37.
