In support of the application, the user shall submit, in units and terms appropriate for evaluation, the information required in § 51.064, herein. The following information shall also be submitted:
      (1)   Where known, the nature and concentration of any pollutants in the discharge which are limited by any city, state, or federal pretreatment standards, and a statement regarding whether or not the pretreatment standards are being met on a consistent basis and if not, whether additional operation and maintenance (O & M) and/or additional pretreatment is required for the user to meet applicable pretreatment standards;
      (2)   If additional pretreatment and/or O & M will be required to meet the pretreatment standards, the shortest schedule by which the user will provide such additional pretreatment shall be submitted to the Superintendent. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. The following conditions shall apply to this schedule:
         (a)   The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (e.g., hiring an engineer, completing preliminary plans, completing final plans, executing contract for major components commencing construction, completing construction and the like).
         (b)   No increment referred to in (B)(1)(a) above shall exceed nine months.
         (c)   Not later than 14 days following each date in the schedule and the final date for compliance, the user shall submit a progress report to the Superintendent including, as a minimum, whether or not it complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps being taken by the user to return the construction to the schedule established. In no event shall more than nine months elapse between such progress reports to the Superintendent.
      (3)   Any other information as may be deemed by the city to be necessary to evaluate the permit application.
   (C)   Within nine months of the promulgation of a national categorical pretreatment standard, the wastewater contribution permit of users subject to such standards shall be revised to required compliance with such standards 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 contribution permit as required by division (B) above of this section, the user shall apply for a wastewater contribution permit within 180 days after the promulgation of the applicable national categorical pretreatment standard. In addition, the user with an existing wastewater contribution permit shall submit to the Superintendent within 180 days after the promulgation of an applicable federal categorical pretreatment standard the information required by divisions (B)(1) and (2) above.
   (D)   Permits may contain the following:
