NR 726.11(4)(f)(f) Geographic position data for each property in compliance with the requirements of s. NR 716.15 (5) (d), unless the agency has directed that the responsible party or other person requesting closure does not need to provide geographic position data for a specific site.

NR 726.11 NoteNote: Geographic position data for properties can be found by using the department database that is available on the internet at http://dnr.wi.gov/topic/Brownfields/rrsm.html.

NR 726.11(5)(a)(a) A site location map that outlines all properties within the contaminated site boundaries on a United States Geological Survey topographical map or plat map in sufficient detail to permit the parcels to be located easily. This map shall identify the location of all municipal and potable wells within 1200 feet of the site. If there is only one parcel, this map may be combined with the map required in par. (b).

NR 726.11(5)(b)(b) A detailed site map of all contaminated properties within the contaminated site boundaries, showing buildings, roads, property boundaries, contaminant sources, utility lines, monitoring wells, and potable wells. This map shall also show the location of all contaminated public street and highway rights-of-way and railroad rights-of-way in relation to the source property and in relation to the boundaries of contamination exceeding applicable standards.

NR 726.11(5)(c)(c) 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:

NR 726.11(5)(c)1.1. A map that shows the location where all soil samples were collected and identifies, with a single contour, the horizontal extent of each area of contiguous residual soil contamination that exceeds residual contaminant levels, as determined under ch. NR 720, within the contaminated site boundaries.

NR 726.11(5)(c)2.2. A geologic cross section showing the vertical extent of residual soil contamination that exceeds residual contaminant levels as determined under ch. NR 720, if one was required as a part of the site investigation report. If there is groundwater contamination on the site that attains or exceeds any ch. NR 140 enforcement standard in addition to residual soil contamination, one geologic cross section may be submitted to show the vertical extent of both soil and groundwater contamination.

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)(b)3.3. A completed groundwater monitoring well information form.

NR 726.11 NoteNote: The Groundwater Monitoring Well Information Form is required in s. NR 716.15. It can be obtained at http://dnr.wi.gov/topic/Groundwater/documents/forms/4400_89.pdf.

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 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.
