§ 51.057 REPORTS, MONITORING AND ANALYSIS OF CONTINUED COMPLIANCE.
   (A)   Periodic reports on continued compliance.
      (1)   Any industrial user subject to a categorical pretreatment standard, and all non-categorical industries, when required by the Authority Board, shall submit to the Authority during the months of June and December, unless required more frequently in the pretreatment standard or by the Authority or the Authority Manager, a report indicating the nature and concentration of pollutants in the effluent which are limited by the categorical pretreatment standards, and as further required by the permit. In addition, this report shall include a record of measured or estimated average and maximum daily flows for the reporting period for the discharge reported in §§ 51.050 or 51.051 except that the Authority may require more detailed reporting of flows. At the discretion of the Authority and in consideration of such factors as local high or low flow rates, holidays, budget cycles and the like, the Authority may agree to alter the months during which the above reports are to be submitted.
      (2)   Where the Authority has imposed mass limitations on industrial users as provided for by 40 C.F.R. § 403.6, the report required by division (A)(1) shall indicate the mass of pollutants regulated by pretreatment standards in the discharge from the industrial user.
      (3)   For industrial users subject to equivalent mass or concentration limits established by the authority in accordance with 40 C.F.R. § 403.6, the report required by division (A)(1) shall contain a reasonable measure of the user’s long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed only in terms of allowable pollutant discharge per unit of production (or other measure of operation), the report required by division (A)(1) shall include the user’s actual average production rate for the reporting period.
   (B)   Notice of potential problems, including slug loading. All categorical and non-categorical industrial users shall notify the POTW immediately of all discharges that could cause problems to the POTW, including any slug loadings, as defined in § 51.002, by the industrial user.
   (C)   Monitoring and analysis to demonstrate continued compliance.
      (1)   The reports required in §§ 51.050, 51.053 and 51.057 shall contain the results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass, where requested by the Authority, of pollutants contained therein which are limited by the applicable pretreatment standards. This sampling and analysis may be performed by the Authority in lieu of the industrial user. Where the Authority performs the required sampling and analysis in lieu of the industrial user, the user shall not be required to submit the compliance certification required under 40 C.F.R. § 403.12(b)(6) and 40 C.F.R. § 403.12(d). In addition, where the Authority itself collects all the information required for the report, including flow data, the industrial user will not be required to submit the report.
      (2)   If sampling performed by an industrial user indicates a violation, the user shall notify the Control Authority within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the Control Authority within 30 days after becoming aware of the violation, except the industrial user is not required to resample if:
         (a)   The Authority performs sampling at the industrial user at a frequency of at least once per month; or
         (b)   The Authority performs sampling at the user between the time when the user performs its initial sampling and the time when the user receives the results of this sampling.
      (3)   The reports required in division (A)(1) shall be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data is representative of conditions occurring during the reporting period. The Authority shall require that frequency of monitoring necessary to assess and assure compliance by industrial users with applicable categorical pretreatment standards and requirements.
      (4)   All analyses shall be performed in accordance with procedures established pursuant to § 51.050(D)(5).
      (5)   If an industrial user subject to the reporting requirement in division (A)(1) monitors any pollutant more frequently than required by the Authority, using the procedures prescribed above, the results of this monitoring shall be included in the report.
