§ 13.20.310. Permit modifications.

Within three months of the promulgation of a categorical standard, permits for users subject to the categorical standards shall be revised to require compliance within the time frame prescribed by the new standard. Where an affected user has not previously submitted an application for a permit as required by Section 13.20.305, the user shall apply within 180 days after the promulgation of the applicable categorical standard. In addition, users with existing permits shall submit to the Director, within 180 days after the promulgation of an applicable categorical standard, a time schedule for compliance with the categorical standard.

The terms and conditions of any permit may be subject to modification by the Director during the term of the permit if discharge limits or requirements, as referenced in Sections 13.20.210 and 13.20.240, are modified or other good cause exists. The user shall be informed of any proposed changes in the permit at least 30 days prior to the effective date of change. Any changes or new conditions in a permit shall include a reasonable time schedule for compliance. Good cause for permit modification includes, but is not limited to, the following reasons:

A.

To incorporate new or revised categorical standards or to incorporate other new or revised federal, state or local 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 permit issuance;

C.

A change in the POTW operations 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 POTW, City employees, the public or the receiving waters;

E.

The user's actual discharge is significantly different than the proposed discharge identified in the user's permit application;

F.

Changes in the requirements of regulatory agencies which affect the City; or

G.

A determination by the Director that modification is appropriate to further the objectives of this chapter.

The Director may at any time rescind the requirement that any NSIU obtain and maintain a Class III permit, at the Director's discretion. With respect to any user that was designated as an SIU solely because of the Director's designation under Section 13.20.105(90), the Director may terminate said user's designation as an SIU and Class II permittee on the Director's later determination that the user no longer has a reasonable potential for adversely affecting the POTW's operation or violating any applicable pretreatment standard, requirement, or discharge limit set forth in this chapter.
