Sampling, recordkeeping and reporting requirements

(a) Sampling. Sampling shall be in accordance with DEQ-approved sampling plans required in this Chapter and OAC 252:606, and OAC 252:690. (b) Recordkeeping. The following recordkeeping requirements apply: (1) Operational records. All IPR SWTPs shall meet the following requirements: (A) Keep a daily record of the operations performed in the treatment process; (B) Record observations, costs, and occurrences related to the operation of the plant; (C) Record the process control tests and laboratory checks; (D) For each required measurement or sample, record: (i) The date, exact place and time of sample and indicate whether a grab sample or composite; (ii) The dates the analyses were performed; (iii) The laboratory and name of the operator who performed each analysis; (iv) The results of all analyses; (v) The instantaneous flow at the time of grab sample collection or a record of each flow taken while collecting a composite sample; and (vi) The method of composite sample calculations and other calculations; (E) If applicable, the results of direct integrity testing and indirect integrity monitoring for membrane filtration as required in OAC 252:626-9-9(f); and (F) Record any other applicable data. (2) Maintain records. The facility owner shall keep records of all control and compliance testing, copies of MORs, DMRs, LMRs, laboratory bench sheets, and other applicable records for at least three (3) years. These records shall be available for inspection by DEQ personnel. (c) Reporting requirements. The following reporting requirements apply: (1) Immediate notification to DEQ. Each IPR SWTP shall report to DEQ within 24 hours if there are any losses of treatment reliability, statistically significant process trends, or changes in the IPR SWTP influent water quality that may cause a negative effect to the IPR SWTP discharge water quality. Should effluent monitoring indicate a violation or serious violation as described in Subchapter 3 of this Chapter, the violation(s) shall be reported to the DEQ within 24 hours and reduction or cessation of discharge may be required. A written report describing the reason(s) for the violation(s) and the steps taken to correct the violation(s) shall be submitted to the DEQ within five (5) days. (2) Reports to be submitted to DEQ. The following reports shall be submitted: (A) Discharge monitoring reports. All DMRs shall be completed and submitted in accordance with the requirements in OAC 252:606, OAC 252:690, and the OPDES discharge permit. 3 (B) Monthly operational reports. Keep a daily record of minimum control tests on forms prepared or approved by DEQ. Make entries for the date samples are collected and indicate where and by whom the observations were made. Include the results of all analyses on the monthly report and use them to calculate weekly or monthly averages. The IPR SWTP shall complete and submit the original of required MOR to DEQ no later than the fifteenth (15) day of the following month. (C) Lake and stream monitoring reports. The LMR form required in Subchapter 11 of this Chapter shall be submitted with the OPDES waterbody monitoring sampling plan for DEQ approval. The report shall include results from samples taken to characterize the accumulation and concentration of conservative substances, trend monitoring, and results from statistical significance tests. The reporting frequency shall be determined by DEQ. (d) Additional reporting, records and/or sampling. Additional sampling, reporting, and/or records requirements may be included by DEQ in any permit, authorization, order, consent decree, closure plan, remediation plan, or other official document issued by DEQ pursuant to applicable law and the provisions of this Chapter.
