Each industrial user discharging or proposing to discharge other than normal sewage either directly or indirectly to the sewage works shall comply with this chapter and shall complete and file the following reports within the time specified by the Director of Public Works and Services.
(a) Discharge report. The information on the discharge report shall be current, and whenever the user’s process changes, the information shall be revised. The information on the discharge report shall include:
(1) The facility name, address, mailing address, sewer account number and SIC number;
(2) The wastewater constituents, characteristics and concentration of any discharge pollutants or substances prohibited or limited by this chapter, as determined by bona fide chemical and biological analyses acceptable to the Director;
(3) The time and duration of discharges;
(4) The average daily wastewater flow rate, including the method of determination and an explanation of all surges of strength and flow rates;
(5) The facility site plan, showing size, elevation and location of all connections to public sanitary sewers, control manholes or sampling access locations and pretreatment equipment;
(6) A description of the facilities, manufacturing processes or service activities on the premises;
(7) A. A statement detailing whether pretreament or additional operation and maintenance procedures are required to comply with this chapter. If such procedures are required to achieve compliance, a schedule for completion of pretreatment equipment or additional operation and maintenance procedures shall be submitted to the Director. The schedule shall contain milestone dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment facilities required for the person to comply with this chapter, including, but not limited to, dates relating to hiring an engineer, completing preliminary plans, executing contracts for major components, commencing construction, completing construction and other acts necessary to achieve compliance with this chapter. The Director shall not permit a time increment for any single step directed toward compliance to exceed nine months. Any violation of this compliance schedule shall be considered a violation of this chapter;
B. The discharger shall submit a progress report to the Director not later than 14 days after each scheduled milestone date and after the final completion date. Each report shall include, at a minimum, a statement detailing whether the person has complied with the increment of progress represented by the milestone date and, if not, the date on which he or she expects to comply with such increment of progress, the reason for the delay and the steps taken to return to the approved schedule. The Director shall not permit the time increment between progress reports to exceed nine months;
(8) Products manufactured or services rendered by type, amount, process and rate of production; and
(9) A. The type and amount of raw materials used.
B. The completed report shall be signed and sent to the Director. If the Director’s evaluation requires additional information, he or she shall request the necessary information from the user and shall notify the user in writing when the report is acceptable.
(b) Strength analysis report.
(1) The information to be submitted on each strength analysis report shall be as follows:
A. The user’s name, address and sewer account number;
B. The date and time the sample was collected; and
C. The results of laboratory analysis in mg/l of the strength of BOD and suspended solids in the user’s discharge to sanitary sewers. The analysis shall be in accordance with methods approved by the Director.
(2) One sample shall be collected and analyzed at least once every six months. If the strength of the discharge is inconsistent, additional tests shall be required.
(3) The sampling procedures used shall ensure that the sample is a representative sample of the flow.
(4) The average strengths, in mg/l, of BOD and suspended solids for each strength surcharge billing period shall be determined from the information submitted in the strength analysis reports for samples collected during the billing period.
(5) The city shall periodically collect and test samples of the discharge. If the information is substantially different from that on the strength analysis reports, the values obtained from such city collected samples may be used to determine surcharge strengths in place of the values in the strength analysis reports.
(c) Compliance report. Within 90 days following the date for final compliance by dischargers subject to a categorical pretreatment standard or any pretreatment provision of this chapter, or 90 days following commencement of the introduction of wastewater into the sewage works by a new discharger, any user subject to a national categorical pretreatment standard or any pretreatment provision of this chapter shall submit a report to the Director indicating the average discharge flow and the nature and concentration of all prohibited or regulated substances contained in his or her discharge. The report shall state whether or not applicable pretreatment standards are being met on a consistent basis, and if not, what measures are necessary to achieve compliance with these standards. The report shall be signed by the chief executive officer of the facility.
(d) Periodic compliance report. Any user subject to a national categorical pretreatment standard or any pretreatment provision of this chapter shall submit a semiannual report to the Director indicating the nature and concentration of prohibited or regulated substances in his or her discharge. Such report shall include a record of all measured average and maximum flows during the reporting period, the results of discharge sampling and analyses and any other information required by the Director.
(e) Analyses methods. All analyses shall be performed by methods approved by the Director.
(f) Private water supply. Any person who discharges to a public sewer and who obtains his or water supply from sources other than city water mains shall report this fact to the Director by filling out forms to be supplied for him or her for such purpose. No person shall fail to file such report.
