Committee keeps exemptions, advances wind-energy bill after debate over setbacks and potential de facto ban

The Senate Insurance and Commerce Committee advanced Senate Bill 437 after adopting amendments intended to protect ongoing projects and to exclude low-elevation areas while imposing new restrictions elsewhere.

Sponsor Senator Bart Hester described the amendments as a compromise intended to preserve existing construction and to protect the Ozark region. Under the amendment, projects currently under construction are exempt from the new rules, and the bill excludes facilities located below 300 feet above sea level from the bill’s permitting and setback requirements. Hester said the change was requested by local senators representing low-elevation areas and was intended to shield active projects.

Opponents — including Simon Mahan, executive director of the Southern Renewable Energy Association — told the committee the bill’s setback and siting provisions would operate as an effective ban across much of the state. Mahan provided a topology-based map showing one-mile setbacks from schools, churches, airports, hospitals and parks; he said the map’s red zones would make most large-scale wind development impossible where the restrictions apply. He also said the statute’s environmental-review and noise standards go well beyond common practice and would discourage private investment.

Supporters said the bill does not ban wind energy but rather imposes stricter, locally focused standards to protect tourism, the Ozarks’ natural resources and other community interests. Sponsor Hester noted amendments carve out active projects and low-elevation areas and emphasized his intent to regulate new projects more strictly in sensitive landscapes.

After debate the committee adopted the amendments and approved the bill on a voice vote. The transcript shows the committee discussed environmental protections, economic-development trade-offs and the bill’s territorial carve-outs at length.
