Senate hearing on large‑volume water user permit bill exposes DNR capacity questions and community concerns
Summary
Senate File 38‑52, which would require separate DNR permits and public notice for large industrial water users, drew broad testimony: environmental groups and private‑well owners urged action after local well problems, industry warned of duplicative rules and agency burden, and DNR staff flagged fiscal and implementation challenges; the bill was laid over for further work.
Senate File 38‑52, a bill that would create a separate DNR permitting pathway for 'large volume' commercial and industrial water users, received extended public testimony and technical questions in committee.
Sponsor Senator Johnson Stewart told the committee the bill targets projects that would use 100 million gallons of water per year or more, or that would exceed 50% of a municipality’s existing authorized pumping volume. The proposal would require large users to secure a DNR permit even when they receive water through a municipal system, create a mandatory public‑comment period, require ongoing monthly reporting of water use to the DNR, and allow environmental review and pump/aquifer testing when warranted.
Environmental advocates and private well owners described local cases they said illustrated the problem. Andrew Hillman of the Minnesota Center for Environmental Advocacy said several proposed projects — including multiple data centers and a bottling plant — have pursued municipal water arrangements that avoid DNR scrutiny, potentially harming private wells and aquifers. One private well owner described hundreds of suffering wells in a community after a major bottling facility expanded; witness accounts included reports of wells running dry and water‑quality problems.
Technical witnesses and DNR staff agreed the statutory priorities place domestic uses first, but they warned the agency is not currently configured to issue a large number of sub‑permits tied to municipal supplies. Jason Michael, assistant division director for ecological and water resources at the DNR, said separating permits or creating a sub‑permit structure will require reprogramming, staff time and a fiscal note; he also raised questions about how geographically targeted notifications would be implemented.
Industry groups including the Minnesota Chamber of Commerce urged caution. Andrew Morley said the amendment’s notification requirement (as drafted) could force the department to notify every municipality in a wide USGS region — a burden that could reach outside Minnesota — and that recent data‑center legislation had already given the DNR authority to request key information and order aquifer tests.
Hydrogeologists and longtime DNR scientists urged the committee to maintain the bill’s goals. Tim Burton, with 37 years in groundwater investigation, and other experts argued the proposal restores the integrity of priority for domestic uses and prevents large industrial users from 'jumping the line' by relying on municipal permits.
Committee members pressed authors and agency staff about whether aquifer tests are mandatory or discretionary, about the length and targeting of public comment periods (30 days was discussed as a typical window), and about fiscal implications. Counsel and DNR staff said the bill preserves DNR discretion to require aquifer testing when the commissioner determines tests are necessary and that, where tests are ordered, results would need to be included in any environmental review.
After extended questioning and cross‑stakeholder discussion, the committee laid SF 38‑52 over so authors and the DNR could work through implementation details.
