      (1)    Significant industrial users as defined herein;
      (2)    Any commercial or industrial user discharging wastes subject to the conditions of Section 931.05(e) and (f).
   (b)    Industrial users required to obtain a wastewater discharge permit shall complete and file with the Service Director an application in the form prescribed by the Service Director. Existing industrial users shall apply for a wastewater discharge permit within ninety days after the effective date of this chapter and shall obtain such permit within 180 days after the effective date of this chapter. Proposed new industrial users shall apply at least ninety days prior to connection to or contributing to the City Wastewater Disposal Facilities and shall have obtained such permit before connection or contribution is made. When new categorical standards are promulgated Industrial Users subject to these standards shall submit an updated wastewater discharge permit application within 180 days of the date on which the standard is promulgated. In support of the application, the user shall submit, in units and terms appropriate for evaluation, the following information: New sources, and sources that become industrial users subsequent to the promulgation of an applicable categorical standard, shall be required to submit to the control authority a report which contains the information listed in paragraphs 931.07(b)(1-8) and 931.08(j) below.  New sources shall also be required to include in this report information on the method of pretreatment the source intends to use to meet applicable pretreatment standards.  New sources shall give estimates of the information requested in paragraphs 931.07(b)(3, 5, 8) below:
      (1)    Name, address and location (if different from the address);
      (2)    SIC number according to the Standard Industrial Classification Manual, Bureau of the Budget, 1972, as amended and a list of any environmental control permits held by or for the facility per OAC 3745-3-06(C)(2);
      (3)    Wastewater constituents and characteristics as determined by a reliable analytical laboratory; sampling and analysis shall be performed in accordance with procedures established by the EPA pursuant to Section 304(g) of the Act and contained in 40 CFR, Part 1136, as amended. Grab samples are required for pH, hexavalent chromium, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. Multiple grab samples collected during a twenty-four hour period for hexavalent chromium, cyanide, total phenols, and sulfides may be composited in the laboratory or in the field. Multiple grab samples collected during a  twenty-four hour period for volatile organics and oil and grease may be composited in the laboratory. All other pollutants are to be measured by flow proportioned samples unless justification for an alternate sampling type, representative of the discharge, is documented by the industrial user. Protocols specified in 40 CFR 136 and relevant USEPA Guidance, including appropriate preservation, must be followed;
      (4)    Time and duration of contribution;
      (5)    Measured average daily and peak wastewater flow rates, including daily, monthly and seasonal variations, if any for:
         A.   Regulated process streams; and
         B.   Other streams as necessary to allow use of the combined waste stream formula of 40 CFR 403.6.
   The City may allow for verifiable estimates of these flows where justified by cost or feasibility considerations as submitted by the user.
      (6)    Site plans, floor plans, mechanical and plumbing plans and details to show all sewers, sewer connections and appurtenances by the size, location and elevation;
      (7)    Description of activities, facilities and plant processes on the premises including all material which are or could be discharged;
      (8)    Requirements for maintaining and retaining plant records relating to wastewater discharge as specified by the Service Director, and affording the Service Director access thereto, including the results of sampling and analysis identifying the nature and concentration (or mass, where required by the standard or control authority) of regulated pollutants in the discharge from each regulated process.  Both daily maximum and average concentration (or mass, where required) shall be reported.  The sample shall be representative of daily operations.  In cases where the standard requires compliance with a BMP or a pollution prevention alternative, the industrial user shall submit documentation as required by the City or the applicable standards to determine compliance with the standard.
      (9)    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. 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, etc.).
         B.    No increment referred to in subsection (b)(9)A, shall exceed nine months.
         C.    No later than fourteen days following each date in the schedule and the final date for compliance, the user shall submit a progress report to the Service Director 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 the 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 Service Director,
      (10)    Each product produced by type, amount, process or processes and rate of production;
      (11)    Type and amount of raw materials processed (average and maximum per day);

   (f)    Permits shall be issued for a specified time period, not to exceed five years. A permit may be issued for any time period of one year or more, but less than five years, or may be stated to expire on a specific date. The permit holder shall apply for permit reissuance not less than 180 days prior to the expiration of the existing permit. The Service Director shall not be required to reissue any permit for the same length of time as the original period which the reissued permit replaces.
   (g)    Wastewater discharge permits are issued to a specific user for a specific operation. A wastewater discharge permit shall not be reassigned or transferred or sold to a new owner, new user, different premises, or a new or changed operation without prior written approval of the Service Director. Any succeeding owner or user shall also comply with the terms and conditions of the existing permit.
   (h)    The City may choose to issue a general permit to a group of similar industrial users, rather permits to each individually. The details of the general permitting scheme follow.
         A.   General permit may be issued for groups of users, including both significant and non-significant industrial users, that have the same of substantially similar types of operations, discharge the same types of wastes, require the same effluent limitations, and require the same or similar monitoring.
         B.   General permits are not available to users subject to production-based categorical pretreatment standards, categorical pretreatment standards expressed as mass of pollutant discharged per day, or industrial users whose limits are based on the combined waste stream formula or net/gross calculations.
         C.   To be covered by a general permit, the significant industrial user is required to file a written request to the City for coverage that identifies its contact information, production processes, the types of waste generated, the location of for monitoring all wastes to be covered by that control mechanism, any requests for a monitoring waiver for any pollutant not present, and any other information the City deems appropriate.
         D.   The City will retain a copy of the general permit, documentation to support the City's determination that a specific significant industrial user meets the general permitting criteria, and a copy of the user's request for coverage at least three years after its expiration.
