15.14.052 Periodic compliance report.
A. All wastewater discharge permit holders that perform self-monitoring shall submit to the director a report indicating the nature of the effluent over the previous reporting period. Reports shall be submitted no less than twice annually as specified in the permit.
1. 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.
2. If a user sampled and analyzed more frequently than was required by the director 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.
3. Any user subject to equivalent mass or concentration limits established by the director or by unit production limits specified in the applicable categorical pretreatment standards shall report production data as outlined in BMC 15.14.051(B).
4. In cases where applicable pretreatment standards and requirements include compliance with BMPs, the user shall submit documentation required by the director in the discharge approval to determine the compliance status of the user.
5. Zero discharge users shall submit periodic reports as required by the director stating that no process waste has been discharged to the POTW.
6. If the director 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 nonregulated flows.
7. Flows shall be reported on the basis of actual measurement; provided, however, that the director may accept reports of average and maximum flows estimated by verifiable techniques if the director determines that an actual measurement is not feasible.
8. Sampling shall be representative of the user’s daily operations and shall be taken in accordance with the requirements specified in Article VI of this chapter.
B. The director may require reporting by users if information or data is needed to establish a sewer charge, determine the treatability of the effluent, or determine any other factor that is related to the operation and maintenance of the POTW.
C. The director may require self-monitoring by the user or, if requested by the user, may agree to perform the periodic compliance monitoring needed to prepare the periodic compliance report required under this section. If the director agrees to perform such periodic compliance monitoring, the user will be charged 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 utility bills. The director is under no obligation to perform periodic compliance monitoring for a user.
D. The director reserves the right to require users to submit reports electronically at such time as the city implements the ability to handle electronic reporting per state and federal rules pertaining to electronic reporting. Before this time, users that choose to send electronic (digital) reports to the city to satisfy the requirements of this section must meet all state and federal signature requirements. The director may still require reporting in traditional format.
E. The director may authorize wastewater discharge permit holders to forego periodic sampling and reporting of a pollutant regulated by a categorical pretreatment standard if such user has demonstrated to the director’s reasonable satisfaction through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge or is present only at background levels from intake water without any increase in the pollutant due to the user’s activities. Any waiver granted pursuant hereto must comply with the requirements of 40 CFR 403.12(e). Waivers granted pursuant hereto do not extend to baseline monitoring reports required under BMC 15.14.050 or initial compliance reports required under BMC 15.14.051. In addition, waivers granted pursuant hereto do not supersede or authorize the user to forego certification processes or requirements specifically established in a categorical pretreatment standard.
