This action finalizes amendments of certain requirements that are contained within the final rule titled "Oil and Natural Gas Sector: Emission Standards for New, Reconstructed, and Modified Sources," published in the Federal Register on June 3, 2016 (2016 Rule). The Environmental Protection Agency (EPA) is finalizing amendments of two narrow provisions of the requirements for the collection of fugitive emission components at well sites and compressor stations: Removes the requirement for completion of delayed repair during unscheduled or emergency vent blowdowns, and provides separate monitoring requirements for well sites located on the Alaskan North Slope.
