(1) An industrial waste discharge permit or control mechanism may be modified for good and valid cause at the written request of the permittee or at the discretion of the WRD Manager. Examples of when a permit may be modified may be including, but not limited to, the following reasons:

(a) To incorporate any new or revised Federal, State, or local pretreatment standards or requirements;

(b) To address significant alterations or additions to the user’s operation, processes, or wastewater volume or character since the time of the industrial waste discharge permit or control mechanism issuance;

(c) A change in the POTW that requires either a temporary or permanent reduction or elimination of the authorized discharge;

(d) Information indicating that the permitted discharge poses a threat to the City’s POTW, City personnel, or the receiving waters;

(e) Violation of any terms or conditions of the industrial waste discharge permit or control mechanism;

(f) Misrepresentations or failure to fully disclose all relevant facts in the industrial waste discharge permit application or in any required reporting;

(g) Revision of or a grant of variance from categorical pretreatment standards pursuant to 40 CFR Part 403.13;

(h) To correct typographical or other errors in the industrial waste discharge permit or control mechanism; or

(i) To reflect a transfer of the facility ownership or operation to a new owner or operator where requested in accordance with Section 11.410.

(2) Permittee modification requests shall be submitted to the WRD Manager and shall contain a detailed description of all proposed changes in the discharge. The WRD Manager may request any additional information needed to adequately prepare the modification or assess its impact. The WRD Manager may deny a request for modification if the change will result in violations of Federal, State, or local laws or regulations; will overload or cause damage to any portion of the sewer system; or will create an imminent or potential hazard to personnel.

(3) If a permit modification is made at the direction of the WRD Manager, the permittee shall be notified in writing of the proposed modification and may have at least 30 days to make appropriate changes. The WRD Manager may require the industrial user to immediately comply with the revised permit.

(4) The adjustment of any existing local limit in accordance with the requirements of this chapter shall necessitate a permit modification for permits containing a previously established local limit. A change in discharge standards may require local limit adjustment.

(5) A modification to the permittee’s discharge permit must be issued before any significant increase is made in the volume or level of pollutants in an existing permitted discharge to the sanitary sewer system.

(6) Changes in the discharge involving the introduction of wastestream or streams not previously included in the industrial waste discharge permit application or involving the addition of new pollutants shall be considered a new discharge, requiring submission of a new permit application.
