(A) Any user subject to a pretreatment standard, after the compliance date of such pretreatment standard, or a new source, after commencement of the discharge into the POTW, or any other significant industrial user, shall submit to the Superintendent during the months of February and November, unless required more frequently in the pretreatment standard or by the Superintendent, a report indicating the nature and concentration, of pollutants in the effluent which are limited by such pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. 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 Superintendent or the pretreatment standard necessary to determine the compliance status of the user. The report shall contain all user self-monitoring results. At the discretion of the Superintendent and in consideration of such factors as local high or low flow rates, holidays, budget cycles, and the like, the Superintendent may agree to alter the months during which the above reports are to be submitted.
(B) The Superintendent may impose mass limitations on users which are using dilution to meet applicable pretreatment standards or requirements, or in other cases where the imposition of mass limitations are appropriate. In such cases, the report required by division (A) of this section shall indicate the mass of pollutants regulated by pretreatment standards in the effluent of the user. These reports 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 Superintendent, of pollutants contained therein which are limited by the applicable pretreatment standards. The frequency of monitoring shall be prescribed in the applicable pretreatment standard. All analysis shall be performed in accordance with procedures established by the Administrator pursuant to Section 304(g) of the Act and contained in 40 CFR, Part 136 and amendments thereto, or with any other test procedures approved by the Administrator. Sampling shall be performed in accordance with the techniques approved by the Administrator.
(C) 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.
(D) Reports of potential problems.
(1) In the case of any discharge, including, but not limited to, accidental discharges, discharges of a nonroutine, episodic nature, a noncustomary batch discharge, a slug discharge or slug load, that might cause potential problems for the POTW, the user shall mmediately telephone and notify the Superintendent of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user.
(2) Within five days following such discharge, the user shall, unless waived by the Superintendent, submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which might be incurred as a result of damage to the POTW, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, penalties, or other liability which may be imposed pursuant to this chapter.
(3) A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees who to call in the event of a discharge described in division (D)(1) above. Employers shall ensure that all employees, who could cause such a discharge to occur, are advised of the emergency notification procedure.
(4) Significant industrial users are required to notify the Superintendent immediately of any changes at its facility affecting the potential for a slug discharge.
(E) Notice of violation/repeat sampling and reporting.
(1) If sampling performed by a user indicates a violation, the user must notify the Superintendent 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 Superintendent within 30 days after becoming aware of the violation.
(2) Resampling by the industrial user is not required if the city performs sampling at the user's facility at least once a month, or if the city performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the city receives the results of this sampling, or if the city has performed the sampling and analysis in lieu of the industrial user.
(3) All monitoring cost shall be the responsibility of the user.
