The terms and conditions of the permit may be subject to modification by the control authority during the term of the permit as limitations or requirements as identified in § 52.35 are amended or other just cause exists. Just cause for a permit modification includes, but shall not be limited to the following.
(A) Material or substantial changes to an industrial user's facility or operation or changes in the characteristics of the industrial user's effluent. It shall be the industrial user's duty to request an application form and apply for a modification of the permit within 30 calendar days of the change, provided the information previously submitted and unchanged need not be resubmitted by the permittee. Failure of the industrial user to so apply shall be considered a violation of this chapter. The control authority may also modify the permit of its own initiative based on its findings or reasonable belief of the above.
(B) Change(s) in Detroit's NPDES permit.
(C) Embodiment of the provisions of a conciliation agreement, court settlement or order.
(D) Any changes necessary to allow Detroit to fulfill its role as control authority.
(E) An industrial user's non-compliance with portions of an existing permit.
(F) A change of conditions within the POTW.
(G) A finding of interference or pass-through attributable to the industrial user.
(H) Amendments to, or promulgation of, national categorical pretreatment standards or requirements. Permittees shall request an application form and apply to the control authority for a modified permit within 90 days after the promulgation of a new or revised national categorical pretreatment standard to which the industrial user shall be subject. Information submitted pursuant to this division shall be confined to that information related to the newly promulgated or amended national categorical pretreatment standard or requirement. However, information previously submitted need not be duplicated, insofar as the previously submitted information continues to be current and applicable. The control authority may also initiate this action. The industrial user shall be informed of any proposed change in its permit at least 60 days prior to the proposed effective date of the change for any change initiated by the control authority, unless the change is the result of any enforcement action taken pursuant to this chapter.
