Rulemaking for Submerged Closed Loop Heat Exchangers

The Minnesota Department of Health (MDH) is amending Minnesota Rules, chapter 4725 (Wells and Borings) to include requirements for the permitting and installation of submerged closed loop heat exchangers (SCLHE) in water-supply wells. A submerged closed loop heat exchanger must not be installed in a water-supply well without a permit granted by the commissioner.

Minnesota Statutes, chapter 103I was amended during the 2023 Legislative Session authorizing the commissioner to adopt rules “to implement requirements for the permitting and installation of submerged closed loop heat exchangers…” Amended language is reflected in the following sections: 103I.005 Definitions, 103I.208 Notification Filing Fees and Permit Fees, 103I.209 Submerged Closed Loop Heat Exchanger System; Requirements, 103I.210 Submerged Closed Loop Heat Exchanger System; Temporary Permits.
