R315-265-94. Ground-Water Monitoring -- Recordkeeping and Reporting

  (a) Unless the ground water is monitored to satisfy the requirements of Subsection R315-265-93(d)(4), the owner or operator shall:

  (1) Keep records of the analyses required in Subsections R315-265-92(c) and (d), the associated ground-water surface elevations required in Subsection R315-265-92(e), and the evaluations required in Subsection R315-265-93(b) throughout the active life of the facility, and, for disposal facilities, throughout the post-closure care period as well; and

  (2) Report the following ground-water monitoring information to the Director:

  (i) During the first year when initial background concentrations are being established for the facility: concentrations or values of the parameters listed in Subsection R315-265-92(b)(1) for each ground-water monitoring well within 15 days after completing each quarterly analysis. The owner or operator shall separately identify for each monitoring well any parameters whose concentration or value has been found to exceed the maximum contaminant levels listed in Appendix III to 40 CFR 265, which is adopted and incorporated by reference.

  (ii) Annually: Concentrations or values of the parameters listed in Subsection R315-265-92(b)(3) for each ground-water monitoring well, along with the required evaluations for these parameters under Subsection R315-265-93(b). The owner or operator shall separately identify any significant differences from initial background found in the upgradient wells, in accordance with Subsection R315-265-93(c)(1). During the active life of the facility, this information shall be submitted no later than March 1 following each calendar year.

  (iii) No later than March 1 following each calendar year: Results of the evaluations of ground-water surface elevations under Subsection R315-265-93(f), and a description of the response to that evaluation, where applicable.

  (b) If the ground water is monitored to satisfy the requirements of Subsection R315-265-93(d)(4), the owner or operator shall:

  (1) Keep records of the analyses and evaluations specified in the plan, which satisfies the requirements of Subsection R315-265-93(d)(3), throughout the active life of the facility, and, for disposal facilities, throughout the post-closure care period as well; and

  (2) Annually, until final closure of the facility, submit to the Director a report containing the results of his or her ground-water quality assessment program which includes, but is not limited to, the calculated, or measured, rate of migration of hazardous waste or hazardous waste constituents in the ground water during the reporting period. This information shall be submitted no later than March 1 following each calendar year.
