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 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 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 director,

d. Each product produced by type, amount, process or processes and rate of production,

e. Type and amount of raw materials processed (average and maximum per day),

f. Number and type of employees, and hours of operation of plant and proposed or actual hours of operation of pretreatment system,

g. Any other information as may be deemed by the city to be necessary to evaluate the permit application.

The city will evaluate the data furnished by the user and may require additional information. After evaluation and acceptance of the data furnished, the city may issue a wastewater contribution permit subject to terms and conditions provided herein.

C. Permit Modifications. Within nine months of the promulgation of a National Categorical Pretreatment Standard, the wastewater contribution permit of significant industrial users subject to such standards shall be revised to require compliance with such standard within the time frame prescribed by such standard. Where a significant industrial user, subject to a National Categorical Pretreatment Standard, has not previously submitted an application for a wastewater contribution permit as required by subsection (B) 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 significant industrial user with an existing wastewater contribution permit shall submit to the director within 180 days after the promulgation of an applicable Federal Categorical Pretreatment Standard the information required by subsection (B)(8) and (B)(9) of this section.

D. Permit Conditions. Wastewater contribution permits shall be expressly subject to all provisions of this chapter and all other applicable regulations, significant industrial user charges and fees established by the city. Permits may contain the following:

1. The unit charge or schedule of significant industrial user charges and fees for the wastewater to be discharged to a community sewer;

2. Limits on the average and maximum wastewater constituents and characteristics;

3. Limits on average and maximum rate and time of discharge or requirements for flow regulations and equalization;

4. Requirements for installation and maintenance of inspection and sampling facilities;

5. Specifications for monitoring programs which may include sampling location, frequency of sampling, number, types and standards for tests and reporting schedule;

6. Compliance schedules;

7. Requirements for submission of technical reports or discharge reports (see subsection (G) of this section);

8. Requirements for maintaining and retaining plant records relating to wastewater discharge as specified by the city, and affording city access thereto;

9. Requirements for notification of the city of any new introduction of wastewater constituents or any substantial change in the volume or character of the wastewater constituents being introduced into the wastewater treatment system;

10. Requirements for notification of slug discharges;

11. Other conditions as deemed appropriate by the city to ensure compliance with this chapter.

E. Permit Duration. Permits shall be issued for a specified time period, not to exceed five years. A permit may be issued for a period less than a year or may be stated to expire on a specific date. The significant industrial user shall apply for permit reissuance a minimum of 180 days prior to the expiration of the user’s existing permit. The terms and conditions of the permit may be subject to modification by the city during the term of the permit as limitations or requirements as identified in subsection (B) of this section are modified or other just cause exists. The user shall be informed of any proposed changes in his or her permit at least 30 days prior to the effective date of change. Any changes or new conditions in the permit shall include a reasonable time schedule for compliance.

F. Permit Transfer. Wastewater contribution permits are issued to a specific user for a specific operation. A wastewater contribution permit shall not be reassigned or transferred or sold to a new owner, new user, different premises, or a new or changed operation without the approval of the city. Any succeeding owner or user shall also comply with the terms and conditions of the existing permit.

1. Compliance Date Report. Within 90 days following the date for final compliance with applicable pretreatment standards or, in the case of a new source, following commencement of the introduction of wastewater into the POTW, any user subject to pretreatment standards and requirements shall submit to the director a report indicating the nature and concentration of all pollutants in the discharge from the regulated process which are limited by pretreatment standards and requirements and the average and maximum daily flow for these process units in the user facility which are limited by such pretreatment standards or requirements. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional O&M and/or pretreatment is necessary to bring the user into compliance with the applicable pretreatment standards or requirements. This statement shall be signed by an authorized representative of the industrial user, and certified to by a qualified professional.

a. Any user subject to a pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the POTW, shall submit to the director during the months of June and December, unless required more frequently in the pretreatment standard or by the director, a report indicating the nature and concentration of pollutants in the effluent which are limited by such pretreatment standards. In addition, this report shall include a record of all daily flows which during the reporting period exceeded the average daily flow reported in subsection (B)(5) of this section. At the discretion of the director and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the director may agree to alter the months during which the above reports are to be submitted.

b. The director may impose mass limitations on users which are using dilution to meet applicable pretreatment standards or requirements, or in other cases where the imposition of mass limitations are appropriate. In such cases, the report required by subsection (G)(2)(a) of this section shall indicate the mass of pollutants regulated by pretreatment standards in the effluent of the user. These reports shall contain the results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass where requested by the director, of pollutants contained therein which are limited by the applicable pretreatment standards. All analysis shall be performed in accordance with procedures established by the administrator pursuant to Section 304(g) of the Act and contained in 40 CFR, Part 136 and amendments thereto or with any other test procedures approved by the administrator. Sampling shall be performed in accordance with the techniques approved by the administrator. Where 40 CFR, Part 136 does not include a sampling or analytical technique for the pollutant in question, sampling and analysis shall be performed in accordance with the procedures set forth in the EPA publication, Sampling and Analysis Procedures for Screening of Industrial Effluents for Priority Pollutants, April 1977, and amendments thereto, or with any other sampling and analytical procedures approved by the administrator.
