Article IV. Reporting Requirements

Section 13.03A.0403 Periodic Compliance Reports [4.3]
  1. Any user that is required to have a discharge permit and performs self-monitoring must comply with 40 CFR §403.12 and submit to the Plant Manager by June fifteenth and December fifteenth of each year, unless required on other dates or more frequently if ordered by the Plant Manager, a report on the nature of its effluent (discharge) over the previous reporting period. The frequency of monitoring is stated in the discharge permit, but no less than two samples per year at least five months apart.
  1. The report must include a record of the nature and concentration (and mass if specified in the discharge permit) of pollutants listed in the discharge permit and a record of all flow measurements (average and maximum) taken at the designated sampling locations as well as any other information required in this chapter or the permit for the reporting period. Production data must be reported if required by the permit. Both daily maximum (maximum daily) and average concentration (or mass, where required) must be reported. If a user sampled and analyzed more frequently than required using methodologies in 40 CFR Part 136 during the reporting period, those results must also be submitted.
  1. If a user subject to the reporting requirement in this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Plant Manager, using the procedures prescribed in Article V of this chapter, the results of the monitoring shall be included in the report. (See 40 CFR §403.12(g)(6)).
  1. In cases where the pretreatment standard requires compliance with a BMP or pollution prevention alternative, the user must submit documentation required by the Plant Manager or the pretreatment standard necessary to determine the compliance status of the user.
  1. Any user subject to equivalent mass or concentration limits established by the Plant Manager or by unit production limits in an applicable categorical pretreatment standard must report production data as stated in SMC 13.03A.0402(B).
  1. If the Plant Manager calculated limits to factor out dilution flows or non-regulated flows, the user is responsible to provide flows from regulated process flows, dilution flows and non-regulated process flows.
  1. Flows must be reported on the basis of actual measurement, provided however, that the Plant Manager may accept reports of average and maximum flows estimated by verifiable techniques if the Plant Manager determines that actual measurement is not feasible.
  1. All wastewater samples must be representative of the user’s daily operations and shall be taken in accordance with the requirements specified in Article 5 of this chapter. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
  1. The Plant Manager may require reporting by users that are not required to have a discharge permit if information or data is needed to establish a sewer rate, determine the treatability of the user’s effluent (discharge), or any other factor related to the operations or maintenance of the POTW.
  1. The Plant Manager may require self-monitoring by the user, or if requested by the user, may but need not agree to perform compliance monitoring needed to prepare compliance reports required under this section. If the Plant Manager performs such service, the user must pay all charges as specified by the Plant Manager as an additional cost of utility service. The City is under no obligation to perform periodic compliance monitoring for a user.
  1. All submittals under this section must be signed as provided in SMC 13.03A.0305(A). Fees will be assessed in accordance with SMC 13.03A.1401.
