The California Air Resources Board (ARB) has posted feedback letters for the February 2016 workshop on proposed regulation of oil and natural gas methane.

Among those who provided feedback letters are the Western States Petroleum Association (WSPA), The California Independent Petroleum Association (CIPA), Southern California Gas Co., San Diego Gas & Electric, Pacific Gas and Electric Company, consulting firms, environmental groups and 10 members of the California Legislature.

The workshop was held to give the public an opportunity to comment on a draft regulation for greenhouse gas emission standards for crude oil and natural gas facilities.

The regulatory initiative was prompted by the California Global Warming Solutions Act of 2006 (AB 32), which calls for reducing greenhouse gas emissions to 1990 levels by 2020.
