NR 812.42(11)(c)2.2. When the well casing height above grade does not comply with subd. 1. a. or b., the well driller or the pump installer shall measure the well casing pipe depth to verify that the well casing pipe depth complies with the rules in effect at the time that the well was constructed, if there is no confirmable well construction report available for the well. Well details, including location, well casing pipe depth, total well depth, distances to possible contaminant sources and well owner information shall be entered on a form and submitted to the department in accordance with s. NR 812.10 (15).

NR 812.42(11)(e)(e) Nonpressurized conduit. When any water well drilling work or pump installing work is performed involving entry into a well that has a nonpressurized conduit and the nonpressurized conduit may continue to be used, the well driller or pump installer shall evaluate the integrity of the nonpressurized conduit and its connection to the well casing pipe by performing a pressure test. The nonpressurized conduit shall be tested and proven watertight under a pressure of not less than 14 psi. The pressure shall be maintained for at least 30 minutes. If the nonpressurized conduit fails the pressure test, the installation shall be changed to a pitless connection. The nonpressurized conduit shall be completely eliminated by cutting off the well casing pipe below the nonpressurized conduit and extending the well casing pipe to at least 12 inches above grade and installing pressurized discharge piping according to the requirements of ss. NR 812.28, 812.31 and 812.32 (4). The extension of the well casing pipe shall be in accordance with sub. (12).

NR 812.42(12)(a)(a) The well casing pipe in the ground may only be extended up if it has the minimum wall thickness for its diameter according to the requirements of s. NR 812.11 (6) Table B and is not in a deteriorated condition. If it does not meet these requirements, the well shall be filled and sealed according to the requirements of s. NR 812.26. The well casing pipe extension (riser pipe) shall meet the requirements of s. NR 812.11 (6) and shall be attached to the top of the existing casing by any of the following methods:

NR 812.43(1)(1) When strict compliance with the requirements of this chapter is not feasible, a variance may be requested. All variance requests shall be in writing, except for situations that may require an immediate response, in which case a variance may be requested verbally from the owner, or the owner’s agent, and a verbal variance may be granted by the department to be followed up with a written confirmation. If the verbal request is made by the owner’s agent, the agent shall provide confirmation of the owner’s concurrence with the request. A variance request shall include the names of the owner or owners and, if known, the well or heat exchange driller, well constructor or pump installer. The reason or reasons compliance with the requirements for this chapter is not feasible shall also be provided. The department may require the owner or the owner’s agent to submit additional information necessary for the department to determine if a variance is justified. The owner or owners or the owner’s agent shall sign the variance request. The department may condition the issuance of a variance by requiring additional construction or installation features to safeguard the groundwater and water supplied by the installation from contamination. Failure to comply with the conditions of a variance or the applicable requirements of this chapter voids the variance approval.

NR 812.43(1)(b)(b) A variance request to the separation distance specified in s. NR 812.08 Table A for an existing water supply well within 1,200 feet of a landfill may be granted by the department where conditions warrant, using the concept of comparable protection. Comparable protection may be provided by appropriate measures including a deeper well casing depth setting, specific grouting materials or methods, specific drilling methodology or additional well water sampling results. These measures will be determined by the department for the purpose of safeguarding the groundwater and the water supply from potential sources of contamination.
