1. keep records throughout the active life of the facility of the analyses required in LAC 33:V.4371.C and E, the associated groundwater surface elevations required in LAC 33:V.4371.F, and the evaluations required in LAC 33:V.4373.B, and, for disposal facilities, throughout the post-closure care period as well; and

2. report the following groundwater monitoring information to the Office of Environmental Services:

a. during the first year when initial background concentrations are being established for the facility, concentrations or values of the parameters listed in LAC 33:V.4371.B.1 for each groundwater monitoring well within 15 days after completing each quarterly analysis. The owner or operator must separately identify for each monitoring well any parameters whose concentration or value has been found to exceed the maximum contaminant levels listed in LAC 33:V.4371.B.1;

b. concentrations or values of the parameters listed in LAC 33:V.4371.B.3 for each groundwater monitoring well, along with the required evaluations for these parameters under LAC 33:V.4373.B. The owner or operator must separately identify any significant differences from initial background found in the upgradient wells, in accordance with LAC 33:V.4373.C. During the active life of the facility, this information must be submitted no later than March 1 following each calendar year; and

c. no later than March 1 following each calendar year, results of the evaluations of groundwater surface elevations under LAC 33:V.4373.M, and a description of the response to that evaluation, where applicable.

1. keep records of the analyses and evaluations specified in the plan, which satisfies the requirements of LAC 33:V.4373.G, 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 Office of Environmental Services a report containing the results of his or her groundwater 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 groundwater during the reporting period. This information must be submitted no later than March 1 following each calendar year.
