Regulating Air Emissions


Air emissions from livestock production are subject to reporting requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) if their emissions reach specified thresholds.

Efforts to regulate air emissions from agricultural sources have been confounded by a lack of information. In the past, EPA has generally not enforced the reporting requirement against livestock production. But large livestock operations are vulnerable to citizen suits for failure to comply with reporting under these statutes (NRC, 2003).

As air emissions from livestock production are receiving increasing attention, EPA is keep updating its “CAFO rule” in recent years, which may have significant effects on the U.S. livestock industry (EPCRA effective on CAFO as of Jan 20, 2009). On April 10, 2009, EPA published proposed mandatory GHG reporting rules in the Federal Register (EPA, 2009).
