A string of public comments at the Des Moines County Board of Supervisors' March 31 meeting focused on a newly developing Bitcoin-mining operation near the ethanol plant and the county's limited zoning authority.
A resident asked how the operation was allowed to begin and said they were worried about noise, fire risk and electricity demand, telling the board the company "will be buying $5,000 worth of electrical energy every month," a figure provided by the speaker. Board members and staff explained that most of Des Moines County has no countywide zoning (the county has zoning only within two miles of Burlington), and that, depending on when work began, an on-site project could claim grandfathering rights if construction had already started.
Planning staff (Jared Glancer) and others discussed regulatory approaches. "We found precedent for standalone ordinances in some counties," a planning official said of wind and solar work, but added that regulating data centers or Bitcoin operations in an unzoned county is an emerging and legally complex issue. Staff recommended researching how other Iowa counties have handled data centers and Bitcoin facilities and whether the county could adopt a standalone industrial-development ordinance or place a moratorium while drafting rules.
A reporter from the Hawkeye asked why the county's wind and solar ordinance included battery storage systems; staff said batteries were included because standalone storage developments can appear independently of wind or solar farms and that batteries store large quantities of energy and pose similar siting concerns.
The board did not adopt new rules at the meeting but directed staff to research legal options, check permits (for wells, DNR or county health requirements), and report back. That follow-up appeared to be the board's immediate next step.
Why it matters: Energy-intensive operations and data centers can alter local infrastructure demand and raise public-safety and environmental questions; residents and the board need clarity on permitting and local authority before projects expand.
What's next: Planning staff will review other counties' approaches, check permit records for the site, and return with options for targeted ordinances or temporary moratoria.
