[EPA-HQ-OAR-2009-0923; FRL-9131-1]; RIN 2060-AP99
EPA is proposing a supplemental rule to require reporting of fugitive and vented greenhouse gas (GHG) emissions from petroleum and natural gas systems, including:
- Onshore petroleum and natural gas production,
- Offshore petroleum and natural gas production,
- Natural gas processing,
- Natural gas transmission compressor stations,
- Underground natural gas storage,
- Liquefied natural gas (LNG) storage,
- LNG import and export terminals, and distribution.
The proposed supplemental rulemaking does not require control of
GHGs, rather it requires only that sources above certain threshold levels
monitor and report emissions. This proposed supplemental rule 40 CFR 98,
subpart W requires annual reporting of fugitive and vented carbon dioxide (CO2)
and methane (CH4) emissions from petroleum and natural gas systems facilities,
as well as combustion-related CO2, CH4, and nitrous oxide (N2O) emissions from
flares at those facilities.
This proposed rule would also establish appropriate thresholds and frequency
for reporting, as well as provisions to ensure the accuracy of emissions
through monitoring, reporting and recordkeeping requirements. This proposed
supplemental rule incorporates a number of changes from the original proposed
rule, including, but not limited to, different methodologies that provide
improved emissions coverage at a lower cost burden to facilities than would
have been covered under the initial proposed rule; the inclusion of onshore
production and distribution facilities; and separate definitions for
“vented” and “fugitive” emissions.
This proposed rule applies to facilities in specific segments of the petroleum
and natural gas industry that emit GHGs greater than or equal to 25,000 metric
tons of CO2 equivalent per year. Reporting would be at the facility level.
Note: many of these facilities are already required to track and report their
combustion-related GHG emissions, according to Subpart C of the April 2009
rulemaking for 40 CFR 98.
