Oil and Natural Gas Sector: Definitions of Low Pressure Gas Well and Storage Vessel

This action finalizes amendments to new source performance standards (NSPS) for the Oil and Natural Gas Sector. On March 23, 2015, the Environmental Protection Agency (EPA) re-proposed its definition of "low pressure gas well" for notice and comment to correct a procedural defect with its prior rulemaking that included this definition. The EPA also proposed to amend the NSPS to remove provisions concerning storage vessels connected or installed in parallel and to revise the definition of "storage vessel." This action finalizes the definition of "low pressure gas well" and the amendments to the storage vessel provisions.
