(A) Modifications of permits shall be subject to the same procedural requirements as the issuance of permits except as listed below. Any changes or new conditions in the permit shall include a reasonable time schedule for compliance:
(1) Changes in the ownership of the discharge when no other change in the permit is indicated;
(2) A single modification of any compliance schedule not in excess of four months; and
(3) Modification of compliance schedules (construction schedules) in permits for new sources where the new source will not begin to discharge until control facilities are operational.
(B) Within nine months of the promulgation of a national categorical pretreatment standard, the wastewater discharge permit of users subject to the standards shall be revised to require compliance with the standard within the time frame prescribed by the standard. Where a user, subject to a national categorical pretreatment standard, has not previously submitted an application for a wastewater discharge permit as required by § 52.052, the user shall apply for a wastewater discharge permit within 180 days after the promulgation of the applicable national categorical pretreatment standard.
(C) A request for a modification by the permittee shall constitute a waiver of the 60-day notice required by G.S. § 143-215.1(b) for modifications.
