Section 329IAC10-20-11. Diversion of surface water, run-on and run-off control systems, and monitoring
-
(a) The owner, operator, or permittee of MSWLFs shall design, construct, and maintain the following:
(1) A run-on control system to prevent flow onto the active portion of the MSWLF during the peak discharge from a twenty-five (25) year storm.
(2) A run-off control system from the active portion of the MSWLF to collect and control at least the water volume resulting from a twenty-five (25) year, twenty-four (24) hour precipitation event.
(b) The owner, operator, or permittee of MSWLFs shall not deposit solid waste in standing or ponded water.
(c) Storm water run-off leaving an MSWLF must be discharged in a manner that does not cause or contribute to erosion or sedimentation or a violation of rules of the water pollution control board at 327 IAC 2-1-6(a).
(d) Appropriate measures shall be planned and installed as part of an erosion and sediment control system.
(e) All storm water quality measures and erosion and sediment control measures must be implemented in accordance with the approved storm water pollution prevention plan and the requirements of this article.
(f) Monitoring requirements shall be as follows:
(1) Each storm water sedimentation basin or series of basins, composed of storm water run-off and any other permitted discharge, shall be monitored as follows:

(2) Each storm water sedimentation basin or series of basins subject to subdivision (1) shall be monitored for any other pollutant which is reasonably expected to be present in the storm water sedimentation basin or series of basins, as well as for any other pollutant as requested by the commissioner.
(3) During the first twelve (12) months after April 1, 2004, an owner, operator, or permittee shall sample and analyze the storm water sedimentation basin or series of basins identified in the pollution prevention plan. The monitoring data taken from this first year event shall be used by the owner, operator, or permittee as an aid in developing and implementing the SWP3. Subsequent semiannual sampling data shall be used to verify the effectiveness of the SWP3 and will aid the owner, operator, or permittee with revising the SWP3 and with the implementation of additional best management practices, as necessary. For new facilities and lateral expansions, the results of monitoring shall be submitted one (1) year after the issuance of the MSWLF permit.
(4) The pH measurement must be taken at the time the grab sample is collected and by using a portable pH meter that has been properly calibrated to the manufacturer's specifications and that provides results displayed in numeric units. A color comparison analysis for pH is not acceptable.
(5) Samples must be collected according to a semiannual schedule. There shall be a minimum of three (3) months between reported sampling events.
(6) Samples must be taken at a point representative of the outflow from the storm water sedimentation basin or series of basins, but prior to entry into surface waters of the state or a municipal separate storm sewer conveyance.
(g) Reporting requirements shall be as follows:
(1) For each measurement or sample taken under this rule, the owner, operator, or permittee of the facility shall record and submit the following information to the commissioner:
(A) The exact place, date, and time of sampling.
(B) The detection limit for each chemical constituent.
(C) The individual who performed the sampling or measurements.
(D) The dates the analyses were performed.
(E) The individual who performed the analyses.
(F) The analytical techniques or methods used.
(G) The results of all required analyses and measurements.
(H) A complete copy of the laboratory report, including chain-of-custody.
(2) The commissioner will evaluate the storm water monitoring results and compare the results with landfill-specific benchmark monitoring cut-off concentrations and numeric limitations as described in NPDES Storm Water Multi-Sector General Permit for Industrial Activities, Federal Register, Vol. 65, No. 210, October 30, 2000. If the storm water monitoring results indicate that the SWP3 has been ineffective in controlling pollutants in storm water discharges from the facility, then the commissioner may require modifications to the SWP3.
(3) All records and information resulting from the monitoring activities, including all records of analyses performed and calibration and maintenance of instrumentation, must be retained for a minimum of three (3) years.
(4) An owner, operator, or permittee shall submit sampling data results to the commissioner within sixty (60) days of obtaining the storm water samples in a sampling event.
(5) An owner, operator, or permittee of an MSWLF that has a discharge which enters a municipal separate storm sewer shall also submit a copy of the sampling data results to the operator of the municipal system upon request.
(6) If an owner, operator, or permittee monitors a pollutant more frequently than required by this rule, using analytical methods referenced in this rule, the results of such monitoring must be reported as additional information. Such increased frequency must also be indicated.
