In 2013, the Minnesota Legislature amended Minnesota Statutes, chapter 103I, to include regulating all bored geothermal heat exchangers (BGHE), not just vertically bored geothermal exchangers. Minnesota Statutes, chapter 103I does not regulate geothermal systems installed by excavation or trenching.

Revised Bored Geothermal Heat Exchanger Rules

The Minnesota Department of Health (MDH) revised Minnesota Rules, chapter 4725 (Wells and Borings) to reflect the 2013 statutory amendments and to accommodate varying BGHE installation methods. The rule revisions were published in the Minnesota State Register on March 15, 2021. The new rules are effective as of March 22, 2021.

Note: Until the Revisor's official rules are posted on their website you can review the new BGHE rules below. See: Revised Rules Indicating Added and Deleted Language.
