In this article, we review EPA’s NSPS OOOOb for centrifugal and reciprocating compressors used at onshore natural gas processing plants, compressor stations, and centralized production facilities.

Learn about leak detection and repair (LDAR) inspection requirements for well sites and compressor stations, as outlined in NSPS OOOOb.

In our two-part series about the economics of CCUS, we examine the potential revenue streams applicable to a broad range of CCUS projects and the typical capital costs associated with CCUS project investment.

In October 2023, EPA promulgated the final PFAS reporting and recordkeeping rule from the TSCA Section 8(a)(7) amendment by the 2020 NDAA. Originally intended to commence in November 2024 through November 2025, the agency issued a direct final amendment changing the reporting period to July 2025 through July 2026. EPA cites a lack of sufficient technological capacity and delays in reporting application development to accept data any sooner.

EPA estimates these final rules will apply to nearly 9,500 gasoline distribution facilities. The changes will affect storage tanks, loading operation controls, equipment leak detection, performance testing, and compliance reporting requirements.

The EPA has published the Final HON Rule. Learn more about the fenceline monitoring requirements and what affected facilities can do to prepare.

The new rule expands the requirement for FRPs to include facilities handling certain hazardous substances exceeding established reporting thresholds. These facilities must now plan for potential worst-case discharges of listed substances.

In April 2024, the EPA updated its Interim PFAS Destruction and Disposal Guidance, a key step in the ongoing efforts to manage PFAS. Read more about the updates here.
