A. Any industrial user that is required to have an industrial waste discharge permit and performs self-monitoring shall comply with all applicable requirements under 40 CFR 403.12, or any superseding amendments thereto, and submit to the City during the months specified in the permit, unless required on other dates or more frequently by the City, a report indicating the nature of the effluent over the previous reporting period. The frequency of monitoring shall be as prescribed within the industrial waste discharge permit. At a minimum, industrial users shall sample their discharge at least twice per year.
B. The report shall include a record of the concentrations (and mass if specified in the wastewater discharge permit) of the pollutants listed in the wastewater discharge permit that were measured and a record of all flow measurements (average and maximum) taken at the designated sampling locations and shall also include any additional information required by this Chapter or the wastewater discharge permit. Production data shall be reported if required by the wastewater discharge permit. Both daily maximum and average concentration (or mass, where required) shall be reported. If an industrial user sampled and analyzed more frequently than what was required by the City or by this chapter, using methodologies in 40 CFR Part 136, it must submit all results of sampling and analysis of the discharge during the reporting period.
C. Any industrial user subject to equivalent mass or concentration limits established by the City or by unit production limits specified in the applicable categorical standards shall report production data as outlined in Section 8-4-2-24-B of this Chapter.
D. If the City calculated limits to factor out dilution flows or non-regulated flows, the industrial user will be responsible for providing flows from the regulated process flows, dilution flows and non-regulated flows.

E. Flows shall be reported on the basis of actual measurement, provided, however, that the City may accept reports of average and maximum flows estimated by verifiable techniques if the City determines that an actual measurement is not feasible.
F. Discharges sampled shall be representative of the industrial user's daily operations and samples shall be taken in accordance with the requirements specified in Section 8-4-2-34 of this Chapter.
G. The City may require reporting by industrial users that are not required to have an industrial wastewater discharge permit if information or data is needed to establish a sewer charge, determine the treatability of the effluent, or determine any other factor which is related to the operation and maintenance of the sewer system.
H. The City may require self-monitoring by the industrial user or, if requested by the industrial user, may agree to perform the periodic compliance monitoring needed to prepare the periodic compliance report required under this section. If the City agrees to perform such periodic compliance monitoring, it may charge the industrial user for such monitoring, based upon the costs incurred by the City for the sampling and analyses. Any such charges shall be added to the normal sewer charge and shall be payable as part of the sewer bills. The City is under no obligation to perform periodic compliance monitoring for an industrial user. (Ord. 582, 10-9-2019)
