While Congress is attempting to roll back a federal regulation on methane emissions, the California Air Resources Board approved a landmark rule that regulates methane emissions from onshore and offshore oil and gas production and storage facilities.
"While the federal government may be going backwards, California is going to be moving forwards,” Tim O’Connor, director of the California oil and gas program at the Environmental Defense Fund, told reporters in a conference call Wednesday, reported Rob Nikolewski for the Union-Tribune.
On the federal level, O'Connor was referring to the use of the Congressional Review Act to "overturn an Obama drilling rule" to limit the venting and flaring of methane emissions on federal lands. [More information at end of post.]
On the state level, he was referring to agenda item #17-3-6 (pdf) at Thursday's California Air Resources Board meeting.
"California air quality officials have approved what are widely considered to be the most rigorous and comprehensive regulations in the country for controlling methane emissions, a move that helps cement the state’s status as a standard-bearer for environmental protection," reports Dominic Fracassa for the San Francisco Chronicle. The rule, "Greenhouse Gas Emission Standards for Crude Oil and Natural Gas Facilities" (pdf) "seek(s) to curb methane emissions at oil and gas production plants by up to 45 percent over the next nine years."
Methane as a greenhouse gas
Critics of the rule were quick to note that the oil and gas industry is not the largest emitter of the second most prevalent greenhouse gas, pound for pound about 25 times greater than CO2 over a 100-year period, according to the U.S. Environmental Protection Agency. According the the pie chart on page 5 of the CARB presentation (pdf), agriculture is responsible for 58 percent, followed by landfills at 20 percent, pipelines at 9 percent, and oil and gas extraction and storage at 4 percent.
“Our industry is not the top emitter of methane in the state, yet this rule will add to the nation’s toughest regulations that our operators must follow, such as cap and trade,” Rock Zierman, the chief executive officer of industry trade group the California Independent Petroleum Association, said in a statement. “We hope that regulators will provide ample time for implementation and ensure that the program is fairly and consistently enforced across the state.”

Federal Methane Emissions rule
A few final notes on the federal attempt to rescind the aforementioned rule on venting and flaring of methane from oil and natural gas drilling sites on federal and Indian lands. On Feb 3, the House passed a resolution (H.J.Res.36) to reverse the Department of Interior's Methane and Waste Prevention Rule. E&E News reports on March 22 that Senate Environment and Public Works Chairman John Barrasso (R-Wyo.) has encountered difficulties in rounding up votes for their resolution, S.J. Res. 11.
[P]roponents of the measure say that with two GOP senators — Maine's Susan Collins and South Carolina's Lindsey Graham — expected to oppose it, the margin of error is razor thin.

Congress Fails to Roll Back Obama-Era Methane Emissions Rule
Current events that have nothing to do with the environment but everything to do with politics might have caused the defeat of a bill to overturn an Obama-era rule designed to reduce methane emissions on federal lands.

Two environmental regulations enacted by the Obama Administration are expected to be rescinded under the Congressional Review Act: the Stream Protection Rule that protects water from mountaintop coal mining and limits on flaring methane emissions.
