relating to health; adding variance considerations related to submerged closed loop
heat exchanger systems; proposing coding for new law in Minnesota Statutes,
chapter 103I.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF MINNESOTA:

Section 1.

new text begin [103I.2091] SUBMERGED CLOSED LOOP HEAT EXCHANGER
SYSTEM; VARIANCES.
new text end

new text begin Subdivision 1. new text end

new text begin Variance. new text end

new text begin In addition to any variances considered under Minnesota Rules,
part 4725.0410, to the isolation distance requirements under Minnesota Rules, part 4725.4450,
for a water supply well containing a submerged closed loop heat exchange, the commissioner
shall consider request for a variance for a water supply well containing a submerged closed
loop heat exchanger for the sole purpose of heating and cooling if the applicant demonstrates
that strict compliance with the isolation distance requirement would impose an undue burden
on the applicant's ability to design and install an effective submerged closed loop heat
exchanger system. In evaluating variance requests, the commissioner shall consider factors
critical to the effective design and operation of the submerged closed loop heat exchanger
system, including but not limited to the need for adequate spacing between submerged
closed loop heat exchanger wells to optimize thermal performance and the necessity of
minimizing lateral piping lengths to reduce energy loss and improve system efficiency.
