Late last month, the Environmental Protection Agency signed off on a final rule requiring that additional categories of sources begin to track and report greenhouse gas emissions under EPA’s earlier GHG reporting rule.
Readers will recall the original rule, published in October, 2009, regulated 41 kinds of sources of methane, carbon dioxide, and nitrous oxide ,and other GHG emissions, requiring reporting when the rule becomes effective. The new rule adds Magnesium Production, Underground Coal Mines, Industrial Wastewater Treatment, and Industrial Landfills, to the list of sources that have reporting requirements. With this final rule the Agency has taken action on all outstanding source categories and subparts from the April 2009 original proposal for the greenhouse gas reporting program.
EPA promulgated the regulations to require monitoring and reporting of various major greenhouse gas emissions. In general, this national greenhouse gas reporting program is supposed to provide EPA with accurate and timely GHG emissions data from facilities that emit 25,000 metric tons or more of carbon dioxide equivalent (CO2e) per year. This data is supposed to provide a better understanding of where GHGs are coming from and will guide development of the best possible policies and programs to reduce emissions, says the EPA.
Underground coal mines, magnesium production facilities, industrial waste landfills and industrial wastewater treatment facilities that meet the reporting threshold must begin monitoring GHG emissions on January 1, 2011 and must submit the first annual report to EPA by March 31, 2012. These GHG reporting rules are genearaly viewed as the first steps toward implementing GHG emissions limits and related climate change regulations.
