Air Emissions Reporting in Iowa

Iowa dairy farms with more than 700 mature dairy cattle emitting more than 100 pounds of ammonia and hydrogen sulfide within a 24 hour time frame are required by the EPA to report air releases to local and state agencies. A rule came out exempting dairy farms with less than 700 mature dairy cows from reporting emissions.

According to a press release, the Iowa DNR, "estimates that about 2,000 livestock or poultry operations could be required to report."
