(A) All industrial users discharging or proposing to discharge industrial wastewater to the city's sewer system must maintain records of its raw materials and usage, processes, effluent flows, pollutant concentrations and related factors. These records must be necessary to demonstrate compliance with the requirements of this chapter and any applicable federal or state pretreatment standards.
(B) Any industrial user subject to the reporting requirements of this chapter must be required to retain for a minimum of three years any records of monitoring activities and results. This period of retention must be extended during the course of any unresolved litigation regarding the industrial user or city sewer system or when requested by the director or the approval authority.
(C) All records related to compliance with pretreatment standards must be made available for inspection and copying at the company facility or if located elsewhere, at the other location, to officials of the EPA, approval authority and the director (40 CFR § 403.12(o)(2)).
(D) The owner and/or occupant of any premises or facility discharging industrial wastewater into the city's sewer system must install at its or their own expense suitable monitoring equipment as may be required by this chapter to facilitate the accurate observation, sampling, and measurement of regulated constituents. The equipment must be maintained in proper working order and kept safe and accessible at all times.
(E) If the Director requires or the owner or operator chooses to install a flow meter, the flow meter must be calibrated every six months and a photocopy of the calibration must be sent to the Director. The calibration must be performed by one of the following: the manufacturer or a qualified civil engineer. Flow charts are to be held by the user for a minimum of three years and made available to the director upon request. Totalizer readings must be recorded daily and every month a report must be submitted to the director showing total daily flows and total monthly flow.
(F) All industrial users required to periodically sample and analyze their wastewater must use sampling methods and sampling locations approved by the Director. For each sample collected and analyzed the user must maintain a record of:
(1) The date, exact place, method and time of sampling and the names of the person or persons taking samples;
(2) The dates and analyses where performed;
(3) Who performed the analysis;
(4) The analytical techniques/methods used;
(5) The results of the analyses.
(G) Whether constructed on public or private property, the approved sampling point must be constructed in accordance with the city requirements. An industry may request approval from the city for sampling wells installed before the effective date of the ordinance codified in this chapter, which meet the design and accessibility requirements for sampling purposes.
