Chapter 14 SEWERAGE*



Section 14-118 Federal categorical standards.

 

    The categorical pretreatment standards found at 40 CFR  chapter  I, subchapter N, parts 405--471 are hereby incorporated.

    (a)    Upon the promulgation of the federal  categorical pretreatment standards for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed pursuant to  this chapter for sources in that subcategory, shall immediately supersede the limitations locally  imposed. The state environmental protection division shall notify all affected users of the new  standard and applicable reporting requirements.

    (b)    Where the city's wastewater treatment system achieves consistent removal of pollutants limited by federal pretreatment standards, the city may apply to the state for modification of specific limits in the federal pretreatment standards. "Consistent removal" means reduction  in the  amount of a pollutant or alteration of the nature of the pollutant by the wastewater treatment  system to a less toxic or harmless state in the effluent which is achieved by the system for ninety-five  (95) percent of the samples taken when measured according to the procedures set forth in  section 403.7(c)(2) of title 40 of the Code of Federal Regulations, part 403--"General Pretreatment Regulations for Existing and New Sources of Pollution" promulgated pursuant to the Act. The city may then modify pollutant discharge limits in the federal pretreatment standards if the requirements contained in 40 CFR, part 403, Section 403.7, are fulfilled and prior approval from the approval authority is obtained.

    (c)    Within either one hundred eighty  (180) days after the effective date of a categorical  pretreatment standard, or the final administrative decision on a category determination under 40  CFR 403.6(a)(4), whichever is later, existing categorical users currently discharging to or scheduled to discharge to the POTW shall submit to the superintendent a report which contains the  information listed below. At least ninety (90) days prior to commencement of their discharge, new sources, and sources that become categorical users subsequent to the promulgation of an applicable categorical standard, shall submit to the superintendent a report which contains the information  listed in subsections (d)(1)--(8), below. A new source shall report the method of pretreatment it intends to use to meet applicable categorical standards. A new source also shall give estimates of  its anticipated flow and quantity of pollutants to be discharged.

    (d)    Users described above shall submit  the information set forth below:

    (1)    Identifying information. The name and address of the facility, including the name of the  operator and owner;

    (2)    Environmental permits. A list of any environmental control permits held by or for the facility;

    (3)    Description of operations. A brief description of the nature, average rate of production,  and standard industrial classifications of the operation(s) carried out by such user. This description  should include a schematic process diagram which indicates points of discharge to the POTW from  the regulated processes;

    (4)    Flow measurement. Information showing the measured average daily and maximum daily  flow, in gallons per day, to the POTW from regulated process streams and other streams, as  necessary, to allow use of the combined wastestream formula set out in 40 CFR 403.6(e);

    (5)    Measurement of pollutants.

        a.    The categorical  pretreatment standards applicable to each regulated process,

        b.    The results  of sampling and analysis identifying the nature and concentration, and/or  mass, where required by the standard or by the superintendent, of regulated pollutants in the discharge from each regulated process. Instantaneous, daily maximum, and long-term average  concentrations, or mass, where required, shall be reported. The sample shall be representative of  daily operations and shall be analyzed in accordance with procedures set out in section 14-122(b),

        c.    Sampling must be performed in accordance with procedures set out in Section 14-122(c);

    (6)    Certification. A statement, reviewed by the user's authorized representative and certified by a qualified professional, indicating whether 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 to meet the pretreatment standards and requirements;

    (7)    Compliance schedule. 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 and/or O&M. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. A compliance schedule  pursuant to this section must meet the requirements set out in section 14-118(e);

    (8)    Signature and certification. All baseline monitoring reports must be signed and certified in accordance with section 14-67.

    (e)    Compliance schedule progress reports. The following conditions shall apply to the compliance schedule required by this chapter:

    (1)    The schedule shall contain progress increments 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 (such events include, but are not limited to, hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, and beginning and conducting routine  operation);

    (2)    No increment referred to above  shall exceed nine (9) months;

    (3)    The user shall submit a progress  report to the superintendent no later than fourteen (14) days following each date in the schedule and the final date of compliance including, as a minimum,  whether or not it complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the user to return to the established schedule; and

    (4)    In no event shall more than nine  (9) months elapse between such progress reports to the  superintendent.

    (f)    Reports on compliance with categorical pretreatment standard deadline. Within ninety (90) days following the date for final compliance with applicable categorical pretreatment standards, or in the case of a new source following commencement of the introduction of wastewater into the POTW, any user subject to such pretreatment standards and requirements shall submit to the superintendent a report containing the information described in section 14-118. For users subject to equivalent mass or concentration limits established in accordance with the  procedures in 40 CFR 403.6(c), this report shall contain a reasonable measure of the user's long-term  production rate. For all other users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period. All compliance reports must be signed and certified in accordance with section 14-67.

    (g)    Periodic compliance reports.

    (1)    All significant industrial users  shall, at a frequency determined by the superintendent but in  no case less than twice per year (in June and December), submit a report indicating the nature and concentration of pollutants in the discharge which are limited by pretreatment standards and the  measured or estimated average and maximum daily flows for the reporting period. All periodic compliance reports must be signed and certified in accordance with section 14-67.

    (2)    All wastewater samples must be  representative of the user's discharge. Wastewater  monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good  working order shall not be grounds for the user to claim that sample results are unrepresentative of  its discharge.

    (3)    If a user subject to the reporting  requirement in this section monitors any pollutant more  frequently than required by the superintendent, using the procedures prescribed in section 14-122, the results of this monitoring shall be included in the report.
