What is in the Final Rule?What is in the Final Rule?
• On December 18, 2008 EPA published a final rule (effective January 20, 2009) that clarified which livestock facilities must report air emissions from their facilities
• Administrative exemption for animal feeding operations from reporting air emissions that normally occur from raising farm animals under CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act)
• Animal feeding operations that are not large Concentrated Animal Feeding Operations (CAFOs) according to NPDES permitting rules, are also exempt from reporting under EPCRA (Emergency Planning and Community Right to Know Act)
What is a “large” animal What is a “large” animal feeding operation (AFO)?feeding operation (AFO)?
• For the listed animals, a “large” AFO is one confining at least:
• 700 ---------- mature dairy cows, whether milked or dry • 1,000 ------- veal calves • 1,000 ------- cattle other than mature dairy cows or veal
calves (“cattle" includes, but is not limited to, heifers, steers, bulls and cow/calf pairs.)
• 2,500 -------- swine each weighing 55 pounds or more • 10,000 ------ swine each weighing less than 55 pounds • 55,000 ------ turkeys • 30,000 ------ laying hens or broilers, if the farm uses a
liquid manure handling system • 125,000 ----- chickens (other than laying hens) if the
farm uses other than a liquid manure handling system
• 82,000 ------- laying hens, if the farm uses other than a liquid manure handling system
How do I calculate air How do I calculate air releases?releases?
• The amount of ammonia and hydrogen sulfide released varies depending on climate, temperature, type of confinement, and manure handling
• The owner/operator must perform “good faith” estimates
• Although EPA does not endorse a specific method, several universities have worksheets available on-line (listed on last slide)
