(A) Permits are issued for a period of one year. The terms and conditions of the permit may be subject to modification as limitations or requirements in this chapter are modified or as a result of pretreatment standards and/or requirements promulgated pursuant to §§ 307 et seq. of the Clean Water Act, 33 U.S.C. §§ 1317 et seq.
(B) The user must be informed of the proposed changes in the user's permit 30 days before the effective date of the change. Any new conditions in the permit must include a reasonable compliance schedule to be proposed by the industrial user and approved by the Director. The compliance schedule will allow the user time to modify the industrial process sufficiently to comply with the new permit changes.
(C) Permits issued to each industrial user must be based on the user's typical discharge rate, peak discharge rate and wastewater constituents and characteristics as described in the user's permit application or through the Director's knowledge of the history of the user's discharge.
(D) The user is required to promptly notify the Director of any significant changes in the user's operation that may affect the user's discharge rate, peak flow rate, wastewater constituents or characteristics (40 CFR § 403.12(j)).
