NR 140.28(5)(c)1.1. The remedial action for restoring contaminated soil or groundwater, and any infiltrated or injected contaminated water and remedial material, shall achieve the applicable response objectives required by s. NR 140.24 (2) or 140.26 (2) within a reasonable period of time. NR 140.28(5)(c)2.2. The type, concentration and volume of substances or remedial material to be infiltrated or injected shall be minimized to the extent that is necessary for restoration of the contaminated soil or groundwater and be approved by the department prior to use. NR 140.28(5)(c)3.3. Any infiltration or injection of contaminated water or remedial material into soil or groundwater will not significantly increase the threat to public health or welfare. NR 140.28(5)(c)4.4. No uncontaminated or contaminated water, substance or remedial material will be infiltrated or injected into an area where a floating non-aqueous phase liquid is present in the contaminated soil or groundwater. NR 140.28(5)(c)5.5. There will be no expansion of soil or groundwater contamination, or migration of any infiltrated or injected contaminated water or remedial material, beyond the edges of previously contaminated areas, except that infiltration or injection into previously uncontaminated areas may be allowed if the department determines that expansion into adjacent, previously uncontaminated areas is necessary for the restoration of the contaminated soil or groundwater, and the requirements of subd. 1. will be met. NR 140.28(5)(c)6.6. All necessary federal, state and local licenses, permits and other approvals are obtained and all applicable environmental protection requirements will be complied with. NR 140.28 NoteNote: The issuance of a wastewater discharge permit by the department is required prior to the infiltration or injection of substances or remedial material into unsaturated soil or groundwater for discharges, as defined by s. 283.01 (4), Stats. A wastewater discharge permit establishes the effluent or injection limits for substances or remedial material which may be infiltrated or injected into unsaturated soil or groundwater. A temporary exemption granted under this subsection applies to substances or remedial material which may enter groundwater or may be detected at a point of standards applications; it does not apply to substances or remedial material infiltrated or injected into unsaturated soil. NR 140.28(5)(d)(d) Remedial action design, operation and monitoring criteria. In addition to providing information on how the requirements under par. (c) will be met, the application shall specify the following information where applicable. NR 140.28(5)(d)1.1. The remedial action design, operation and soil and groundwater monitoring procedures to insure compliance with the requirements under par. (c) and applicable criteria under this paragraph. NR 140.28(5)(d)2.2. The level of pre-treatment for contaminated groundwater prior to reinfiltration or reinjection. NR 140.28(5)(d)3.3. The types and concentrations of substances or remedial material being proposed for infiltration or injection. NR 140.28(5)(d)4.4. The volume and rate of infiltration or injection of contaminated groundwater or remedial material. NR 140.28(5)(d)5.5. The location where the contaminated groundwater or remedial material will be infiltrated or injected. NR 140.28(5)(e)(e) Granting an exemption. The department may only grant a temporary exemption under this subsection at the same time or after the department has approved the remedial action. When the department grants an exemption under this subsection, it shall follow the exemption procedures included in sub. (6) and shall require the owner or operator of the facility, practice or activity to comply with the requirements and criteria in pars. (c) and (d). The temporary exemption shall also include: NR 140.28(5)(e)1.1. The expiration date of the temporary exemption. The expiration date shall be selected to achieve the applicable response objectives required by s. NR 140.24 (2) or 140.26 (2) within a reasonable period of time, not to exceed 5 years from the effective date of the exemption. The temporary exemption may be reissued following a department review of information documenting the performance of the remedial action and a successful demonstration that reissuance of the exemption is necessary to achieve the response objectives required by s. NR 140.24 (2) or 140.26 (2).necessary relating to the temporary exemption. NR 140.28(5)(f)(f) Responses to exemption violations. If the department determines that the conditions or requirements specified in the temporary exemption are not being met, the department may: NR 140.28(5)(f)1.1. Require that the owner or operator of the facility, practice or activity revise the remedial action design, operation or monitoring procedures in accordance with par. (d). All revisions shall comply with the requirements established under pars. (c) and (e) and may require approval from the department prior to implementation. NR 140.28(5)(f)2.2. Revoke the exemption and require implementation of an alternate remedial action to restore soil or groundwater quality. NR 140.28(6)(6) Exemption procedures. If the department grants an exemption under this section for a substance or a remedial material, it shall specify: NR 140.28(6)(a)(a) The substance or remedial material to which the exemption applies; NR 140.28(6)(b)(b) The terms and conditions of the exemption, which may include an alternative concentration limit, under which the department may seek a response under s. NR 140.24 or 140.26 relating to the substance or remedial material; and NR 140.28 HistoryHistory: Cr. Register, September, 1985, No. 357, eff. 10-1-85; am.

APPENDIX I TO TABLE 1
PUBLIC HEALTH GROUNDWATER QUALITY STANDARDS NR 140.28 Note1Chemical Abstracts Service (CAS) registry numbers are unique numbers assigned to a chemical substance. The CAS registry numbers were published by the U.S. Environmental Protection Agency in 40 CFR Part 264, Appendix IV NR 140.28 Note2Common synonyms include those widely used in government regulations, scientific publications, commerce and the general public. Common synonyms should be cross-referenced with CAS registry number to ensure the correct substance is identified. Table 1 contains groundwater quality standards for pesticide active ingredients and their degradation breakdown products. Active ingredients are the chemicals in a pesticide product that kill, control, or repel pests. Pesticide products are given proprietary “trade names” by the pesticide product manufacturer. A database of pesticide products approved for use in Wisconsin is accessible through the Department of Agriculture, Trade and Consumer Protection (DATCP) home web page (search for “pesticide database”). The U.S. Environmental Protection Agency (EPA) also maintains a database of registered pesticide products, called the Pesticide Product and Label System (PPLS), on its website. These pesticide product databases can be searched by active ingredient to find the pesticide products, and their trade names, that contain a specific pesticide active ingredient.
NR 140.28 Note3This is a combined chemical substance which includes cis 1,3-Dichloropropene (CAS RN 10061-01-5) and trans 1,3-Dichloropropene (CAS RN 10061-02-6).
NR 140.28 Note4Polychlorinated biphenyls (CAS RN 1336-36-3); this category contains congener chemicals (same molecular composition, different molecular structure and formula), including constituents of Aroclor-1016 (CAS RN12674-11-2), Aroclor-1221 (CAS RN 11104-28-2), Aroclor-1232 (CAS RN 11141-16-5), Aroclor-1242 (CAS RN 53469-21-9), Aroclor-1248 (CAS RN 12672-29-6), Aroclor-1254 (CAS RN 11097-69-1), and Aroclor-1260 (CAS RN 11096-82-5).
NR 140.28 Note5Xylene (CAS RN 1330-20-7) refers to a mixture of three isomers, meta-xylene (CAS RN 108-38-3), ortho-xylene (CAS RN 95-47-6), and para-xylene (CAS RN 106-42-3).
