This bill proposes the addition of variance considerations for submerged closed loop heat exchanger systems in Minnesota Statutes, specifically under chapter 103I. It introduces a new section, [103I.2091] SUBMERGED CLOSED LOOP HEAT EXCHANGER SYSTEM; VARIANCES, which allows the commissioner to consider variance requests for water supply wells containing these systems. The bill stipulates that such variances can be granted if the applicant can demonstrate that strict adherence to existing isolation distance requirements would create an undue burden on their ability to effectively design and install the system. The commissioner is tasked with evaluating these requests based on critical factors that affect the design and operation of the heat exchanger systems. Additionally, the bill includes an REVISOR INSTRUCTION that directs the revisor of statutes to renumber an existing section (103I.208, subdivision 3) to section 103I.2091, subdivision 2, and to make any necessary adjustments to statutory cross-references to align with this change. This restructuring aims to streamline the legal framework surrounding submerged closed loop heat exchanger systems and enhance their implementation in Minnesota.
