(A) Significant non-categorical industrial users. Significant non-categorical industrial users shall, at a frequency determined by the Pretreatment Coordinator but in no case less than twice per year (on dates specified by the village) submit a report with a description of the nature, concentration, and flow of the pollutants required to be reported by the village. These reports shall be based on sampling and analysis performed in the period covered by the report, and performed in accordance with the techniques described in 40 CFR part 136 and amendments thereto. This sampling and analysis may be performed by the village in lieu of significant non-categorical industrial user. Where the village itself collects all the information required for the report, the significant non-categorical industrial user will not be required to submit the report.
(B) Categorical industrial users.
(1) All categorical industrial users shall, at a frequency determined by the Pretreatment Coordinator but in no case less than twice per year (in July and January), submit a report indicating the nature and concentration of pollutants in the discharge which are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. At the discretion of the village and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the village may agree to alter the months during which the above reports are to be submitted. All periodic compliance reports must be signed and certified in accordance with § 54.055 of this chapter.
(2) All wastewater samples must be representative of the user's discharge. 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.
(4) Where the village has imposed mass limitations on users as provided for by 40 CFR 403.6(d), the report required by division (A) of this section shall indicate the mass of pollutants regulated by the pretreatment standards in the discharge from the industrial user.
(5) For users subject to equivalent mass or concentration limits established by the village in accordance with the procedures in 40 CFR 403.6(c), the report required by division (A) of this section shall contain a reasonable measure of the user's long term production rate. For all other 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) of this section shall include the user's actual average production rate for the reporting period.
