Possible Amendment to Rules Governing Wells and Borings, Minnesota Rules, Chapter 4725, Concerning Bored Geothermal Heat Exchangers; Revisor’s ID Number R-04192

Subject of Rules. The Minnesota Department of Health requests comments on its possible amendment to rules governing wells and borings, Minnesota Rules, chapter 4725, regarding bored geothermal heat exchangers. The department is considering rule amendments to reflect amendments to Minnesota Statutes, chapter 103I by Minnesota Session Law, chapter 108, article 12, section 11. The department is requesting your comments on possible amendments to rules including: licensing of persons who construct, repair or seal bored geothermal heat exchangers; permitting of bored geothermal heat exchangers; construction, use and sealing of bored geothermal heat exchangers; and other department-specific issues.

Persons Affected. The amendments to the rules would likely affect persons who construct, repair, or seal bored geothermal heat exchangers and persons who own bored geothermal heat exchangers. The amendments may indirectly affect persons who use groundwater.

Statutory Authority. Minnesota Statutes, section 103I.101, subd. 1, gives the Commissioner of Health, the “powers reasonable and necessary to effectively exercise the authority granted in this chapter.” Minnesota Statutes, section103I.101, subdivision 5, specifically directs the Commissioner to adopt rules governing licensing, design and construction standards, reporting, and a variety of other issues related to wells and borings. A bored geothermal heat exchanger is a type of boring.

Public Comment. Interested persons or groups may submit comments or information on these possible rules in writing until further notice is published in the State Register that the department intends to adopt or to withdraw the rules. The department has discussed the rulemaking with the Advisory Council on Wells and Borings, established under Minnesota Statutes, section 103I.105, and the council will have the opportunity to comment on the rules.

The department will not publish a notice of intent to adopt the rules until more than 60 days have elapsed from the date of this request for comments. The department plans to appoint an advisory committee, comprised of members who work with bored geothermal heat exchangers, to review the issues for rule development and comment on the possible rules.

Rules Draft. The department is working on a draft of possible rule amendments and anticipates that the draft of the amendments will be available following the period for Request for Comments but before the publication of the Notice of Intent to Adopt Rules. Persons interested in receiving a copy of the draft rule amendments when they become available should contact Nancy La Plante as directed below. Information on this rulemaking, including schedule, rulemaking documents, and rule implementation will be available on the MDH Well Management Section website at:
