Any changes or new conditions in the permit shall include a reasonable time schedule for compliance as set forth in § 257-89A (13)(a). Within nine months of the promulgation of a National Categorical Pretreatment Standard, the wastewater discharge permit of users subject to such standards shall be revised to require compliance with such standard within the time frame prescribed by such standard. Where a user subject to a National Categorical Pretreatment Standard has not previously submitted an application for a wastewater discharge permit as required under § 257-82 , the user shall apply for a wastewater discharge permit within 90 days after the promulgation of the applicable National Categorical Pretreatment Standard.

In addition, the user with an existing wastewater discharge permit shall submit to the Chief Plant Operator and/or Superintendent of Sewers, within 90 days after promulgation of an applicable National Categorical Pretreatment Standard, the information required by § 257-90 herein.
