The Iowa Senate followed the House’s lead by passing an air quality bill for all livestock facilities in the state. The House version requires a three-year study of hydrogen sulfide, ammonia and odor around livestock operations before emissions limits are set.

Under the bill, the Iowa Department of Natural Resources would be required to collect air samples from livestock operations around the state. The agency would use the results to develop new standards that would be subject to public hearing before being adopted.

The proposal also prohibits state agencies from adopting pollution limits more severe than federal standards.

Supporters contend the bill is a proactive approach to air quality legislation, while opponents say the study delays any real enforcement.

Gov. Tom Vilsack joined the critics by saying there needs to be a better balance between a strong livestock industry and a strong environment.

The amended bill will go back to the House for approval.
