NR 726.11(5)(d)1.1. A geologic cross section, if one was required under ch. NR 716, that includes the vertical extent of residual contamination in soil and groundwater, the location and extent of the source of the contamination, isoconcentrations for all groundwater contamination attaining or exceeding ch. NR 140 preventive action limits that remains when case closure is requested, water table and piezometric elevations, location and elevation of geologic units, bedrock and confining units, if any. NR 726.11(5)(d)2.2. An isoconcentration map of the contaminated properties within the contaminated site boundaries, if such a map was required under ch. NR 716. An isoconcentration map shall show the areal extent of groundwater contamination attaining or exceeding ch. NR 140 preventive action limits and the areal extent of groundwater contamination attaining or exceeding ch. NR 140 enforcement standards, with the groundwater flow direction indicated, using the most recent data, with sample collection dates identified. If an isoconcentration map was not required under ch. NR 716, submit a map showing the horizontal extent of contamination exceeding applicable standards based on the most recent data; or where standards have not been promulgated, the horizontal extent of contamination remaining after the remedial action. NR 726.11(5)(d)3.3. A groundwater flow map, representative of groundwater movement at the site. If groundwater flow direction varies by more than 20 degrees over the history of water level measurements at the site, 2 groundwater flow maps showing the maximum variation in groundwater flow direction shall be submitted. NR 726.11(5)(e)(e) For sites or facilities where samples were collected other than soil or groundwater, include a map showing the sampling locations and results, with type of sample and collection date identified. NR 726.11(6)(6) Data summary tables. For information submitted for sites or facilities where inclusion on a department database is required under s. NR 726.07, shading and cross–hatching may not be used on data summary tables unless prior approval is obtained from the department. All the following information shall be included in a department database attachment to the case closure request: NR 726.11(6)(a)(a) Soil. For sites or facilities where soil contamination exceeds residual contaminant levels as determined under ch. NR 720 at the time that case closure is requested include a table of the analytical results showing results for the most recent samples, for all contaminants found in pre–remedial sampling, with sample collection dates identified. NR 726.11(6)(b)(b) Groundwater. For sites or facilities where groundwater attains or exceeds any ch. NR 140 enforcement standard at the time that case closure is requested, include: NR 726.11(6)(b)1.1. A separate table of only the 8 most recent analytical results from all monitoring wells, and any potable wells for which samples have been collected, with sample collection dates identified. NR 726.11(6)(b)2.2. A table including, at a minimum, the previous 8 water level elevation measurements from all monitoring wells, with the date measurements were made. If free product is present at the site, it shall be noted in the table. NR 726.11(6)(c)(c) Other. For sites or facilities where samples other than soil or groundwater were collected, include a table specifying the sample type, sample number or location, sample results, and collection date. NR 726.11(7)(7) Documentation for monitoring wells. For sites or facilities where a monitoring well has not been abandoned in accordance with the requirements of ch. NR 141 at the time of case closure, the following information shall be included in a department database attachment to the case closure request. NR 726.11(7)(a)(a) A site location map with the surveyed locations identified on the map for those groundwater monitoring wells that have not yet been abandoned; NR 726.11(7)(b)(b) The well construction report for each monitoring well that needs to be abandoned; and NR 726.11(7)(c)(c) The deed with legal description for each property on which a monitoring well is located. NR 726.11 NoteNote: This would include wells that have not been located for abandonment, wells that the property owner has requested to keep and not abandon at this time, and those wells required by the agency under s. NR 726.05 (7) (a) for continued monitoring after closure. Proper abandonment is required once the wells are no longer used. The well construction report, form 4400-113A can be obtained at http://dnr.wi.gov/topic/Groundwater/documents/forms/4400_113_1_2.pdf. NR 726.11 HistoryHistory: CR 12-023: cr. Register October 2013 No. 694, eff. 11-1-13. NR 726.13NR 726.13 Authority and approvals for case closure. NR 726.13(1)(a)(a) The agency may grant case closure under this section, if all the following conditions are met: NR 726.13(1)(a)2.2. It has been documented, in the case closure request that is submitted to the agency in compliance with the requirements of s. NR 726.09, that all applicable public health and environmental laws, including chs. NR 700 to 754, have been complied with, or where ch. NR 140 enforcement standards are the only standards that are attained or exceeded, that the criteria in s. NR 726.05 (6) are satisfied. NR 726.13(1)(b)(b) The agency may not close a case under this chapter if, at any time in the future, the remaining level of contamination is likely to do any of the following: NR 726.13(1)(b)1.1. Pose a threat to public health, safety, or welfare or the environment. NR 726.13(1)(b)2.2. Cause a violation of a ch. NR 140 groundwater quality enforcement standard at any applicable point of standards application, except where the department has granted an exemption under s. NR 140.28 for a specific hazardous substance or the criteria under s. NR 726.05 (6) are met.
