(E) Specifications for monitoring programs which may include sampling location; frequency of sampling; number, type and standards for tests; and reporting schedule;
(F) Compliance schedules;
(G) Requirements for submission of technical reports or discharge reports;
(H) Requirements for maintaining and retaining, for a minimum of three years, all plant records relating to pretreatment and/or wastewater discharge as specified by the city, and affording city access thereto as required by 40 CFR 403.12(o)(2);
(I) Requirements for notification of the city or 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;
(J) Requirements for notification of slug discharges;
(K) The permit may require the user to reimburse the city for all expenses related to monitoring, sampling and testing performed at the direction of the City Administrator and deemed necessary by the city to verify that the user is in compliance with the said permit;
(L) Other conditions as deemed appropriate by the city to ensure compliance with this chapter.
(Ord. 96-10, passed 10-17-96) Penalty, see § 51.999
(A) Where an effluent from a categorical industrial process(es) is mixed prior to treatment with wastewater other than that generated by the regulated process, fixed alternative discharge limits may be derived for the discharge permit by the City Administrator. These alternative limits shall be applied to the mixed effluent and shall be calculated using the combined wastestream formula and/or flow-weight average formula as defined in § 51.002.
(B) Where the effluent limits in a categorical pretreatment standard are expressed only in terms of mass of pollutants per unit of production (production-based standard), the City Administrator may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or of effluent concentration for purposes of calculating effluent permit limitations applicable to the permittee. The permittee shall be subject to all permit limits calculated in this manner under 40 CFR 403.6(c) and must fully comply with these alternative limits.
(C) All categorical users subject to production-based standards must report production rates annually so that alternative permit limits can be calculated if necessary. The categorical user must notify the City Administrator 30 days in advance of any major change in production levels that will affect the limits for the discharge permit.
(Ord. 96-10, passed 10-17-96)
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 user shall apply for permit reissuance a minimum of 60 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 §§ 51.060 through 51.068 are modified or other just cause exists. The user shall be informed of any proposed changes in their 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.
(Ord. 96-10, passed 10-17-96)
Industrial user permits are issued to a specific user for a specific operation. An industrial user permit shall not be reassigned or transferred or sold to a new owner, new user, different premises, or a new or changed operation without a 30-day prior notification to the City Administrator and provision of a copy of the existing permit to the new owner. The City Administrator may deny the transfer of the permit if it is deemed necessary.
(Ord. 96-10, passed 10-17-96)
Within 90 days following the date for final compliance with applicable categorical pretreatment standards or, in the case of a new user, following commencement of the introduction of wastewater into the POTW any user subject to federal categorical pretreatment standards and requirements shall submit, to the City Administrator, a report indicating the nature and concentration of all pollutants in the discharge from the regulated process which are limited by categorical pretreatment standards and requirements and the average and maximum daily flow for these process units in the user's facility which are limited by such categorical standards and requirements. The report shall state whether the applicable categorical pretreatment standards and requirements are being met on a consistent basis and, if not, what additional pretreatment and time schedule is necessary to bring the user into compliance with the applicable categorical pretreatment standards or requirements. This statement shall be signed by an authorized representative of the user.
(Ord. 96-10, passed 10-17-96) Penalty, see § 51.999
(A) All significant industrial users shall submit, to the City Administrator, every six months (on dates specified in the industrial user permit) unless required more frequently by the permit, a report indicating, at a minimum, the nature and concentration, of pollutants in the effluent which are limited by such pretreatment standards or discharge permit. In addition, this report shall include a record of all daily flows which during the reporting period exceeded the average daily flow. At the discretion of the City Administrator and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the City Administrator may agree to alter the months during which the above reports are to be submitted.
(B) All analyses shall be performed by a laboratory acceptable to the city. Analytical procedures shall be in accordance with procedures established by the U.S. EPA Administrator pursuant to Section 304(g) of the Act and contained in 40 CFR 136 and amendments thereto and 40 CFR 261 or with any other test procedures approved by the U.S. EPA Administrator. Sampling shall be performed in accordance with the techniques approved by the U.S. EPA Administrator.
(C) Where 40 CFR 136 does not include a sampling or analytical technique for the pollutant(s) 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 U.S EPA Administrator.
(D) A baseline monitoring report (BMR) must be submitted to the City Administrator by all categorical industrial users at least 90 days prior to initiation of discharge to the sanitary sewer. The BMR must contain, at a minimum, the following:
(1) Production data: a process description, SIC code number, raw materials used, chemicals used, final product, pretreatment industrial category (if applicable), and a schematic which indicated points of discharge to the sewer system.
(2) Identifying information to include name, address of facility, owner(s), contact person and any other permits held by the facility.
(3) Wastewater characteristics: total plant flow, types of discharges, average and maximum flows from each process.
(4) Nature/concentration of pollutants: analytical results for all pollutants regulated by this chapter and/or any applicable federal pretreatment standard and sample type and location. All analyses must conform with 40 CFR 136 and amendments thereto.
(5) Information concerning any pretreatment equipment used to treat facility's discharge.
(E) New sources shall give estimates of the information requested in divisions (3) and (4) above, but at no time shall a new source commence discharge(s) to the public sewer of substances that do not meet provisions of this chapter. All new sources must be in compliance with all provision of this chapter, state and federal pretreatment regulations prior to commencement of discharge to the public sewer.
(Ord. 96-10, passed 10-17-96) Penalty, see § 51.999
(A) All significant industrial users must notify the City Administrator within 24 hours of first becoming aware of a permit violation. This notification shall include the date of violation, the parameter violated and the amount in exceedance.
(B) The user shall immediately repeat the sampling and analysis of the parameter(s) in question and submit the results to the City Administrator within 30 days after becoming aware of the violation.
Exception to this regulation is only if the city performs the sampling within the same time period for the same parameter(s) in question.
