The Decorah City Council is moving toward tighter rules for data centers and cryptocurrency mining centers, though no specific project was approved in the first-reading vote.

What the proposed ordinance would do

The ordinance would establish requirements for any future data center or cryptocurrency mining center proposed in Decorah. The planned rules would address zoning, utility use and environmental standards.

No project approved

The vote dealt with prospective regulation rather than a development application. A first-reading approval did not authorize construction or endorse a particular data center project.
