A closure review fee would be required when a complete closure request is then submitted.
NR 726.05(6)(6) Criteria for closure for sites or facilities with groundwater contamination. For sites or facilities with groundwater contamination that attains or exceeds ch. NR 140 enforcement standards at the time that case closure is requested, including sites or facilities contaminated with petroleum products discharged from a petroleum storage tank that are eligible for closure under ch. NR 726, the responsible party or other person requesting closure shall submit a case closure request to the agency for the site that documents that all of the following criteria are satisfied, if applicable: NR 726.05(6)(a)(a) Adequate source control measures have been taken which include all of the following: NR 726.05(6)(a)1.1. Whether regulated or registered under ch. ATCP 93 or not, all existing underground storage tanks have been removed, permanently closed or upgraded to prevent new discharges of hazardous substances to the groundwater that would violate ch. NR 140. The same requirement applies to all new and replacement underground storage tanks not regulated under ch. ATCP 93. NR 726.05 NoteNote: The intent of this requirement is to ensure that source control measures are taken which prevent new or continuing releases, regardless of whether or not the tank is regulated under ch. ATCP 93. NR 726.05(6)(a)2.2. All new and replacement underground storage tanks regulated under ch. ATCP 93 have been constructed and are being monitored in accordance with ch. ATCP 93. NR 726.05(6)(a)3.3. All other existing tanks, pipes, barrels or other containers which may discharge a hazardous substance have been removed, contained or controlled to prevent, to the maximum extent practicable, new discharges of hazardous substances to the groundwater that would violate ch. NR 140. NR 726.05(6)(a)4.4. Where applicable, immediate and interim actions have been taken in accordance with ch. NR 708 to protect public health, safety, or welfare or the environment. NR 726.05(6)(a)6.6. The concentration and mass of a substance and its breakdown products in groundwater have been reduced due to naturally occurring physical, chemical and biological processes as necessary to adequately protect public health and the environment, and prevent groundwater contamination from migrating beyond the boundaries of the property or properties which are required to be entered onto the department database. NR 726.05(6)(b)(b) Natural attenuation will bring the groundwater into compliance with ch. NR 140 groundwater quality standards within a reasonable period of time, considering the criteria in s. NR 722.07. NR 726.05(6)(c)(c) The groundwater plume margin is stable or receding, and after case closure, groundwater contamination attaining or exceeding ch. NR 140 preventive action limits will not migrate beyond the boundaries of any property that falls into either one of the following categories: NR 726.05(6)(c)1.1. Properties for which a preventive action limit exemption has been granted. NR 726.05(6)(c)2.2. Properties that have been identified as having existing groundwater contamination that attains or exceeds ch. NR 140 enforcement standards and that will be included on the department database. NR 726.05(6)(d)(d) There is no existing or anticipated threat to public health, safety, or welfare or the environment. NR 726.05(7)(7) General closure criteria. The following shall be required for case closure at all sites or facilities: NR 726.05(7)(a)(a) All monitoring wells and boreholes installed during any response action taken for the site or facility shall be abandoned and documented as abandoned in accordance with s. NR 141.25, except for specific wells that the agency approves of retaining until sampling is no longer required. NR 726.05(7)(b)(b) For sites or facilities where waste or contaminated media was generated during the response action and was stored or treated on–site, all the waste or contaminated media shall be handled and disposed of in accordance with applicable state and federal laws before a case closure request is submitted or approved. NR 726.05(7)(c)(c) Groundwater samples used to determine compliance with ch. NR 140 shall be taken from monitoring wells constructed in accordance with ch. NR 141. The agency may approve an alternative monitoring program designed to show whether groundwater quality standards have been met. NR 726.05(8)(8) Criteria for closure for sites or facilities with vapor contamination. A site or facility is not eligible for closure until the following criteria have been met: NR 726.05(8)(b)(b) Where vapors were present above the vapor risk screening level: NR 726.05(8)(b)1.1. A remedial action has been conducted and reduced the mass and concentration of volatile compounds to the extent practicable; and NR 726.05 NoteNote: Vapor mitigation systems are not considered remedial actions, as they do not reduce the mass or concentrations of the contaminants. Vapor mitigation systems are used to interrupt the vapor migration pathway.
NR 726.05(9)(9) Other. Any other condition for case closure that is necessary to protect public health, safety, or welfare or the environment may be required. NR 726.05 HistoryHistory: CR 12-023: cr.

or may be obtained from any regional office of the department, or by writing to the Department of Natural Resources, Bureau for Remediation and Redevelopment, P.O. Box 7921, Madison, Wisconsin 53707. NR 726.09(2)(2) General requirements. In order to demonstrate that applicable federal, state and local public health and environmental laws have been complied with, and to provide information on the location and nature of any residual contamination at the site or facility, the person who is requesting case closure shall submit all of the following information, that is applicable, as attachments to the case closure request, in the format that is specified in this subsection, and in the order that is specified in the form. NR 726.09(2)(a)(a) Documentation showing that site investigation requirements in ch. NR 716 have been met or, where applicable, documentation which meets the requirements in ch. NR 508, the groundwater assessment requirements in s. NR 140.24 (1) (b), or both. NR 726.09(2)(b)(b) A description of the interim and remedial actions taken at the site or facility. For sites or facilities where residual soil contamination exceeds ch. NR 720 soil standards at the time that case closure is requested, include a demonstration that the remedial action taken, and any interim action that was taken that constituted the final response action for soil contamination, satisfies the requirements of chs. NR 720 and 722, where applicable. NR 726.09(2)(c)(c) Maps and cross sections shall be to scale, and use a graphic scale. The north arrow shall be pointing to the top of the map. NR 726.09(2)(d)(d) For sites or facilities where soil excavation or active soil remediation occurred: NR 726.09(2)(d)1.1. A table of soil analytical results with collection dates identified. Soil analytical data tables shall clearly indicate depth of sample, soil type and whether the sample represents pre-remedial or post-remedial conditions. At sites or facilities where soil excavation occurred, the soil analytical data tables shall indicate whether the soil data point represents soil that was removed or soil that remains in place. NR 726.09 NoteNote: Where a soil performance standard cover is the only action taken, that is not considered active soil remediation. This requirement applies to all sites where soil excavation or active soil remediation occurred, not just those to be included on the department database under s. NR 726.07. NR 726.09(2)(e)(e) Where the agency has required groundwater quality sampling to be conducted, results from a minimum of 8 successive quarterly rounds of sampling to demonstrate compliance with either the applicable requirements of ch. NR 140 or the requirements of s. NR 726.05 (6), unless otherwise directed or approved by the agency. NR 726.09 NoteNote: Under ch. NR 722, alternate sampling schedules may be proposed, based on site geology, contaminants of concern, remedial action applied and redevelopment plans. The department expects that more monitoring may be necessary at complex sites, or where statistical analysis will be used for data evaluation. Conversely, less post-remediation monitoring may be appropriate for certain sites with significant source removal, readily degradable compounds or other well-established site conditions. NR 726.09(2)(f)(f) For sites or facilities with sediment contamination, or soil vapor contamination, sampling data demonstrating that the remedial action selected in accordance with ch. NR 722 has restored the environment to the extent practicable and minimized the harmful effects of the hazardous substances on the air, lands, and waters of the state. NR 726.09(2)(g)(g) Submit to the department documentation that all other closure conditions have been satisfied, within 120 days after the department provides a conditional closure response. NR 726.09 NoteNote: This requirement is meant to cover well abandonment and any other minor condition identified in a conditional closure letter. It does not apply to the continuing obligations specified in the final closure letter. Ch. NR 141 requires the documentation of well abandonment on a form supplied by the department. The well abandonment form, 3300-005, can be accessed at http://dnr.wi.gov/topic/DrinkingWater/documents/forms/3300005.pdf.
