EPA to take fresh look at animal waste emissions reporting; sniffing out comments
Despite a complex history of regulations, legal challenges, and congressional legislation, EPA stands firm when it says that animal waste can generate potentially harmful air emissions of ammonia and hydrogen sulfide. Recently, however, EPA backpedaled a bit with its rulemaking to return reporting requirements to farms for their air emissions from animal waste.
Rather than issue a final rule in 2024, as planned, the agency withdrew the rule and is now soliciting comments through February 15.
What is animal waste?
Animal waste means feces, urine, or other excrement, digestive emission, urea, or similar substances. These are emitted by animals including any form of livestock, poultry, or fish. The term also covers animal waste that is mixed or commingled with bedding, compost, feed, soil, or any other material typically found with that waste.
The problem, EPA says, is ammonia and hydrogen sulfide can be emitted from animal waste. Those two chemicals are listed as:
Historical background
On August 1, 2018, EPA published a final rule to incorporate changes to CERCLA reporting regulations at 40 CFR 302. Those changes were mandated law. Specifically, the Fair Agricultural Reporting Method (FARM) Act of 2018 exempted the reporting of air emissions from animal waste at farms under CERCLA.
Subsequently, on June 13, 2019, EPA issued a final rule to amend the emergency release notification regulations at 40 CFR 355 to implement similar exemptions for animal waste at farms. In addition, the agency added regulatory definitions of “animal waste” and “farm” for this new EPCRA reporting exemption.
However, in January 2021, EPA, under a new administration, reviewed the 2019 final rule and urged a district court to remand the rule. The court granted the remand on February 14, 2022, “without vacatur.” That meant the EPCRA exemption for farms remains in place while EPA reconsiders the rule.
The agency said in the Spring 2022 agenda, that it was working on a rulemaking to roll back the June 2019 rule. EPA tentatively set publication of a proposed rule for June 2023, but that proposal never happened. A final rule was also slated for May 2024.
Latest twist
However, on October 27, 2023, EPA reversed course. The agency withdrew its rulemaking to reconsider the 2019 rule. So, the current 40 CFR 355, which exempts reporting of farm animal waste air emissions, is still on the books. End of story, right? No.
A couple weeks later, on November 17, 2023, EPA published a pre-proposal entitled, “Potential Future Regulation for Emergency Release Notification Requirements for Animal Waste Air Emissions Under EPCRA.” Note that the pre-proposal only impacts 40 CFR 355, not 40 CFR 302.
The agency is looking for information by February 15, 2024, on five topics:
- Health impacts,
- Implementation challenges,
- Costs and benefits,
- The small farm definition and reporting exemption, and
- A national report on animal waste air emissions.
EPA explains that it seeks comments to help it decide:
- Whether to pursue a proposed rule, and
- How best to implement the reinstating of EPCRA reporting from farms, if finalized.
What’s more, the agency is requesting information on any other topics relevant to conducting a future rulemaking on EPCRA reporting of air emissions from animal waste on farms.
Docket EPA-HQ-OLEM-2023-0142 offers a 149-page, technical background document with information about:
- The universe of potentially regulated facilities;
- A cost analysis of a rule;
- The benefits of a rule;
- Small entities potentially affected by the action; and
- The effects on communities with environmental justice concerns.
References to other data, literature, an emissions calculator, and emissions modeling are also provided in the background document.
EPA intends to carefully review all comments received. Then it will determine whether to pursue a proposed rule to reinstate air emission reporting from animal waste at farms under EPCRA.
Key to remember
EPA withdrew the rule to reinstate air emissions reporting of hazardous substances and EHSs in animal waste on farms. Instead, the agency is soliciting comments through February 15 under a new pre-proposal.
