(a) Compliance Data Report. Within ninety (90) days following the date for final compliance by the Significant Industrial User (SIU) with applicable Pretreatment Standards set forth in the Industrial User's Wastewater Discharge Agreement or ninety (90) days following the commencement of the introduction of wastewater into the sewerage system by a new discharger any discharges subject to this chapter shall submit to the Director of Public Service a report indicating the nature and concentration of all prohibited or regulated substances contained in its discharge and the average and maximum daily flow in gallons. The report shall state whether the applicable Pretreatment Standards or Requirements are being met on a consistent basis and, if not, what additional operations and maintenance and/or pretreatment is necessary to bring the discharge into compliance with the applicable Pretreatment Standards or Requirements. This statement shall be signed by an authorized representative of the discharger.
(b) Periodic Compliance Reports. All SIUs shall submit periodic compliance reports indicating the nature and concentration of pollutants in their discharge. The frequencies of monitoring and reporting and the pollutants to be analyzed shall be prescribed in the Wastewater Discharge Agreement. All analyses shall be performed in accordance with procedures established in 40 CFR 136 and amendments thereto. When 40 CFR 136 does not include sampling or analytical techniques or the techniques are inappropriate, alternative methods may be approved by the Director. In addition, the report shall include a record of all measured or estimated average and maximum daily flows during the reporting period. Flows shall be reported on the basis of actual measurement provided, however, where cost or feasibility considerations justify, the Director may accept reports of average and maximum flows estimated by verifiable techniques. The Director, for good cause, considering those factors such as local high or low flow rates, holidays, budget cycles or other extenuating factors, may require the submission of the reports on months other than those specified above. This report shall be signed by an authorized representative of the discharger.
(c) If sampling performed by any discharger indicates a violation, the discharger shall notify the Director within twenty-four (24) hours of becoming aware of the violation. The discharger shall repeat the sampling and analysis and submit the results within thirty (30) days after becoming aware of the violation. If a discharger monitors any pollutant more frequently than required by the Director using the procedures prescribed in 40 CFR 403.12, the results of this monitoring shall be included in the periodic compliance report.
(d) All discharges shall notify the Director in advance of any substantial change in the volume or character of pollutants in their discharge, including the listed or characteristics hazardous wastes for which the Industrial user has submitted initial notification under 40 CFR 403.12(P).
