NR 507.27 Calculation 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.

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.
