Farms no longer have to report air emissions caused by animal waste

The Environmental Protection Agency finalized a rule that will exempt farms from reporting air emissions caused by animal waste. 

Reporting will still be required for the release of animal waste into water. This exemption is in the form of an amendment to EPCRA section 304, where its main purpose is to alert emergency responders of dangerous emissions, like chemical leaks, so they can potentially evacuate a community or alert locals to seek shelter. In a news release, the EPA said this final rule will ensure that “emergency planners and local responders receive reports that focus on these kinds of emergencies.”

This new rule also applies to decomposing animal waste. All other hazardous emissions above a recommended threshold will still need to be reported. 

Animal waste emissions into the air can increase the risk for respiratory health issues like asthma, and also contribute to climate change. A 2013 report from the UN Food and Agriculture Association said that 7.1 gigatons of CO2 emissions can be attributed to the global livestock sector annually.

Iowa is the country’s leading producer of animal and human waste. The Iowa Environmental Focus reported on research engineer Chris Jones’ March study that calculated how many people each livestock group accounted for in terms of the amount of waste it produces, and called it Iowa’s “real population.”

While Iowa has a population of just over 3 million people, this is what Jones found in his March study and lists in his blog:

  • Iowa hogs: equivalent to 83.7 million people
  • Dairy cattle: 8.6 million people
  • Beef cattle: 25 million people
  • Laying chickens: 15 million people
  • Turkeys: 900,000 people
