On March 12, 2018, the EPA finalized amendments to two provisions of NSPS Subpart OOOOa, which regulates certain equipment and activities at oil and natural gas facilities. Both amendments revised requirements for the collection of fugitive emission components at well sites and compressor stations. The first removed the requirement for completion of delayed repair during unscheduled/emergency vent blowdowns. The other provided separate monitoring requirements for well sites located on the Alaskan North Slope. More information about the amendments can be found here. If you have questions regarding the new rule and its applicability to your facility, contact Trinity at (972) 661-8100.
