On Jan.1, 2010, the U.S. Environmental Protection Agency will, for the first time, require large emitters of heat-trapping emissions to begin collecting greenhouse gas data under a new reporting system. This new program will cover approximately 85 percent of the nation’s greenhouse gas emissions and apply to roughly 10,000 facilities.

The only emission source in the agriculture sector covered by the rule is manure management systems at livestock operations with greenhouse gas emissions that meet or exceed the threshold of 25,000 metric tons, according to an EPA Frequently Asked Questions supplement. EPA modeling estimates that just over 100 manure management systems at large livestock operations meet this threshold.

If emissions from a manure management system at a livestock facility are less than 25,000 metric tons of carbon dioxide equivalent per year — either due to the system size, design, or as a result of a methane capture system — then that facility would not be required to report. Methane that is captured for use rather than emitted does not count toward the threshold level.

“This is a major step forward in our effort to address the greenhouse gases polluting our skies,” says EPA Administrator Lisa Jackson. “For the first time, we begin collecting data from the largest facilities in this country, ones that account for approximately 85 percent of the total U.S. emissions. The American public, and industry itself, will finally gain critically important knowledge and with this information we can determine how best to reduce those emissions.”

The goal of EPA’s new reporting system is to provide a better understanding of where greenhouse gases are coming from and guide development of the best possible policies and programs to reduce emissions. The data will also allow businesses to track their own emissions, compare them to similar facilities, and provide assistance in identifying cost effective ways to reduce emissions in the future.
