NR 507.27 NR 507.27Calculation of groundwater standards. The owner or operator shall propose PALs for inorganic monitoring parameters and ACLs and submit PAL or ACL calculations to the department for approval. Calculations of PALs for inorganic monitoring parameters and ACLs shall be based on historical data for each well unless the department determines that data from a well with similar groundwater quality may be used.
NR 507.27(1) (1) Preventive action limits. The owner or operator of an existing solid waste disposal facility shall calculate PALs for inorganic detection monitoring parameters at the direction of the department. Applicants for a proposed solid waste disposal facility shall calculate PALs for inorganic detection monitoring parameters prior to submitting the plan of operation. Detection monitoring parameters are listed in ch. NR 507 Appendix I Tables 1, 1A, and 2. The owner or operator shall calculate PALs for the inorganic detection parameters required at each well in accordance with the methods specified in s. NR 140.20. PALs are not required for pH or temperature. PALs may not be calculated for any parameter that has an ES established in ch. NR 140. The department may require the owner or operator to conduct additional sampling if the department determines that the data used to calculate a PAL is not representative of background water quality.
NR 507.27(2) (2) ALTERNATIVE CONCENTRATION LIMITS. Applicants for proposed solid waste disposal facilities and the owner or operator of an existing solid waste disposal facility may request an exemption and calculate ACLs for any inorganic public health or welfare parameter that has established standards listed in ch. NR 140 Tables 1, 1A, and 2 in accordance with s. NR 507.29.
NR 507.27 Note Note: Guidance for calculations is available from the department of natural resources, bureau of waste management, 101 South Webster Street, P.O. Box 7921, Madison, WI 53707-7921, (608) 266-2111, waste.management@dnr.state.wi.us.

NR 507.28 NR 507.28Evaluation of groundwater standards exceedances. The owner or operator shall determine whether a groundwater standard has been attained or exceeded and whether a PAL or ES applies in accordance with this section.
NR 507.28(1) (1) DETERMINATION OF GROUNDWATER STANDARD EXCEEDANCE. The owner or operator shall determine whether a reported value has attained or exceeded a PAL or ES in accordance with s. NR 140.14.
NR 507.28(2) (2) The point of standards application. The point of standards application to determine if a PAL or ES has been attained or exceeded is specified in either s. NR 140.22 (2) or (3) or s. NR 507.15 (3) (L) 4. for a CCR well. The design management zone and waste boundary are defined in s. NR 140.22 (3). The department may consider an expansion or reduction of the design management zone, excluding CCR wells, in accordance with s. NR 140.22 (3) (b) to (d). For purposes of evaluating compliance, a groundwater monitoring well located at the property line is a point of standards application for an ES.
NR 507.28(3) (3) Demonstration of a false groundwater standard exceedance. The owner or operator may demonstrate, by resampling or other means, that a source other than the solid waste disposal facility caused the contamination or that the sample result attaining or exceeding a groundwater standard is due to an error. The owner or operator shall notify the department of the intent to either begin assessment monitoring or determine that a false exceedance has occurred. The owner or operator shall submit the statement of intent with the notification required in s. NR 507.30 (1). The owner or operator shall submit the written demonstration of false exceedance with the results of the next routine monitoring.
