Methane is a potent greenhouse gas (GHG). Over a
hundred-year-period, it has twenty-five times the global warming potential of
carbon dioxide (CO2). Both the United States Environmental
Protection Agency (EPA) and the federal Bureau of Land Management (BLM)
recently issued rules regulating fugitive methane emissions generated during
oil and gas operations. The rules have the potential to meaningfully reduce GHG
emissions from America’s energy sector, but an uncertain regulatory environment
threatens to undercut the anticipated reduction in GHG emissions.
EPA’s Methane Rule
On June 3, 2016, EPA issued a rule regulating methane
emissions from new, reconstructed, and modified oil and gas operations. Additionally,
the rule directs well operators to inspect existing well sites for methane
leaks and repair any leaks they discover. EPA estimates that the avoided
emissions will total 6.9 million metric tons of CO2 equivalent (CO2e)
in 2020 and 11 million metric tons of CO2e in 2025.[1]
The regulations went into effect on August 2, 2016, and an
initial survey to discover leaks was to have been completed by June 3, 2017. In
April 2017, the new EPA Administrator, Scott Pruitt, announced his intent to
reconsider provisions of the rule and issue a ninety-day stay of the June 3,
2017, compliance date.[2]
On June 5, 2017, EPA issued an official notice of reconsideration of the
regulation and a retroactive ninety-day stay of the compliance date. EPA then
announced its intention to stay the entire rule for two years while it
reconsidered the rule. Environmental groups sued.[3]
On July 3, 2017, the United States Court of Appeals for the District of
Columbia vacated EPA’s stay during the pendency of its reconsideration of the
final rule.
BLM’s Natural Gas
Rule
On November 18, 2016, BLM promulgated a rule regulating
natural gas that is lost during oil and gas operations on federal and Indian
land. BLM estimated that 114 billion cubic feet of natural gas was vented,
flared, or leaked in 2014, which is enough to supply 1.5 million households with
natural gas for a year.[4]
BLM anticipates that the rule will avoid up to 4.5 million tons of CO2e
emissions per year.[5]
In May, the regulation unexpectedly survived a Senate vote to repeal it under
the Congressional Review Act. On June 15, 2017, BLM announced that it is
postponing the compliance deadline for many provisions of the rule during the
pendency of litigation concerning the rule.[6]
A number of states and environmental groups filed a lawsuit challenging BLM’s
stay in the United States District Court for the District of Northern
California.[7]
An Uncertain Future
for Federal Methane Rules?
The methane rules are now in effect, but their future effectiveness
is uncertain in three key respects. First, through notice and comment
rulemaking, the agencies may rescind or modify the rules in the next few years.
Both EPA and BLM have announced their intent to revisit their rules. Operators
may postpone rectifying sources of fugitive emissions in anticipation of a
regulatory rollback. Second, courts could find the rules invalid. Third, the agencies
may deprioritize enforcement of the rules. This is a more serious issue if BLM
deprioritizes enforcement. There is no applicable citizen suit provision that
would allow private citizens to directly sue emitters who violate BLM’s methane
regulations.
EPA’s methane rule is different. Private citizens may directly
sue emitters of fugitive methane emissions covered by EPA’s regulation. However,
private citizens are not as effective as EPA in ensuring widespread compliance
with regulations for two important reasons. First, private citizens may not
leverage the threat of criminal prosecution. Second, private citizens lack the administrative,
financial, legal, scientific, and technical resources available to the federal
government. Nevertheless, the threat of a potential citizen suit should prompt
most emitters to comply with EPA’s regulations for now, even if the
Administration sends clear signals that it will not prioritize enforcement of
EPA’s methane rule.
The regulatory uncertainty and the difficulty in challenging
a possible decision by BLM to deprioritize enforcement of its methane rule threaten
to undercut the potential gains from EPA and BLM’s rules.
