(A) Compliance date report.
(1) 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 Manager 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 the pretreatment standards or requirements.
(2) 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.
(B) Periodic compliance reports.
(1) All categorical industrial users shall submit to the pretreatment coordinator during the months of June and December, unless required more frequently by a pretreatment standard or the industrial user discharge permit, a report indicating the nature and concentration of pollutants in the effluent which are limited by the pretreatment standards or the industrial user discharge permit. At the discretion of the pretreatment coordinator and in consideration of such factors as local high or low flow rates, holidays, budget cycles and the like, the pretreatment coordinator may agree to alter the months during which the above reports are to be submitted.
(2) 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 pursuant to § 304(g) of the Act and contained in 40 C.F.R. Part 136 and amendments thereto or with any other test procedures approved by the U.S. EPA. Sampling shall be performed in accordance with the techniques approved by the U.S. EPA.
(3) Where 40 C.F.R. 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 U.S. EPA.
(4) All industrial users shall retain all pretreatment records for a minimum of three years, as required by 40 C.F.R. § 403.12(o)(2).
(C) Baseline monitoring.
(1) A baseline monitoring report (BMR) must be submitted to the pretreatment coordinator 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:
(a) Production data including a process description, SIC code number, raw materials used, chemicals used, and final product(s) produced;
(b) Name of facility contact person;
(c) Wastewater characteristics such as total plant flow, types of discharges, average and maximum flows from each process;
(d) Nature and concentration of pollutants discharged by the public sewer system that are regulated by this chapter, state and/or federal pretreatment standards and sample type and location; and
(e) Information concerning any pretreatment equipment used to treat the facility’s discharge.
(2) All new sources of industrial discharge must be in compliance with all provisions of this chapter prior to commencement of discharge.
(D) Permit violations; repeat sampling; reports. All significant industrial users must notify the pretreatment coordinator within 24 hours of first becoming aware of a permit violation. This notification shall include the date of the violation, the parameter violated and the amount in exceedance. Within 30 days of first becoming aware of a permit violation, the significant industrial user must resample for the parameter violated and submit this sample analysis to the pretreatment coordinator, unless the pretreatment coordinator. Resampling by the industrial user is not required if GWSC performs sampling at the user’s facility at least once a month, or if the GWSC performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the GWSC receives the results of this sampling, unless the pretreatment coordinator, on behalf of the city, conducts monitoring of this parameter within that 30-day period.
