NESHAP for Oil and Natural Gas Production (40 CFR part 63, subpart HH) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Oil and Natural Gas Production (40 CFR Part 63, Subpart HH) were proposed on February 06, 1998, and promulgated on June 17, 1999, only for major sources. On July 8, 2005, a supplemental proposal was proposed for area sources with the final rule, effective date on January 03, 2007. The rule was subsequently amended on August 16, 2012 to include emission sources for which standards were not previously developed. These regulations apply to emission points located at both new and existing oil and natural gas production facilities that are both major and area sources. A major source of hazardous air pollutants (HAP) is one that has the potential to emit 10 tons or more of any single HAP or 25 tons or more of total HAP per year; an area source is one with the potential to emit less than this. New facilities include those that commenced either construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart HH. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
