(A) Any 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 and submit to the city during the months of July and January, 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, users shall sample their discharge at least twice per year. In cases where the pretreatment standard requires compliance with a best management practice (BMP) or pollution prevention alternative, the user must submit documentation required by the Director of Utilities or the pretreatment standard necessary to determine the compliance status of the user.
(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 ordinance 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 a 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 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 § 51.191(B).
(D) If the city calculated limits to factor out dilution flows or nonregulated flows, the 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 user's daily operations and samples shall be taken in accordance with the requirements specified in § 51.210.
(G) The city may require reporting by 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 user or, if requested by the user, may agree to perform any 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 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 a user.
(I) A facility determined to be a non-significant categorical industrial user by the Director of Utilities and Engineering pursuant to must annually submit the signed certification statement below:
“Based on my inquiry of the person or persons directly responsible for managing compliance with the categorical pretreatment standards under 40 CFR , I certify that, to the best of my knowledge and belief that during the period from , to , [months, days, year]:
(1) The facility described as [facility name] met the definition of a non-significant categorical industrial user as described in 40 CFR § 403.3(v)(2);
(2) The facility complied with all applicable pretreatment standards and requirements during this reporting period; and
(3) The facility never discharged more than 100 gallons of total categorical wastewater on any given day during this reporting period. This compliance certification is based upon the following information: .
(J) Industrial users that have been deemed significant industrial users that are non-categorical users are required to submit self-monitoring reports in accordance with this section.
