Proposed Amendments to Mandatory Greenhouse Gas Reporting Rule

March 22nd, 2010 – Environmental Protection Agency Administrator Dr. Lisa Jackson proposed amendments to the general provisions (subpart A) for the mandatory reporting of greenhouse gases. Under this proposal are three new provisions that facilities reporting greenhouse gas emissions under part 98 of the Mandatory Greenhouse Gas Reporting rule would be required to report:

  1. Their corporate parent companies,
  2. The North American Industry Classification System codes that apply to their facility,
  3. And whether or not emissions reported include emissions from a cogeneration unit.

These three reporting requirements would be included in time for the first annual greenhouse gas emissions reports scheduled to be submitted to the Environmental Protection Agency on March 31st, 2011, and in all years afterwards. The underlying reporting requirement already in place is intended to collect accurate emissions data in order to make informed policy decisions. The current provisions require annual reporting of industrial greenhouse gas emissions from large sources, fossil-fuel suppliers, automobile engine and vehicle manufacturers, and any facilities that emit 25,000 metric tons or more of greenhouse gases in the United States.

The comment period for the rule amendments is currently open.
