In early October, the EPA proposed a new rule for the Toxics Release Inventory (TRI) that could change the way we currently report on PFAS. Currently, TRI requires individual reporting on 196 PFAS, but the new proposal introduces the concept of PFAS categories. We dive into the impact these changes could have on current TRI reporting and compliance if the proposal is approved.

In the first of a three-part series on Traveler Information Messages (TIMs), we explore TIMs essential role in enhancing road safety and operational efficiency. In the second, we dive deeper into the in-vehicle delivery of TIMs and their potential to improve driving conditions.

On October 7, 2024, EPA released new water quality limits for 10 PFAS to protect aquatic life. States and tribes can use these limits to develop their own standards under the Clean Water Act.

California’s SCAQMD Rule 1178 was amended to further reduce VOC emissions from storage tanks at petroleum facilities. Explore strategies and key factors to consider when adjusting operations and records management practices to effectively adapt air compliance programs.

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 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.

Trihydro acquires Alloy Group's Engineering and Consulting Division, expanding Trihydro's capabilities in the mining sector.

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.

The EPA has issued final Maximum Contaminant Levels (MCLs) for six per- and polyfluoroalkyl substances (PFAS). The final rule aims to place further controls on PFAS as outlined EPA’s Action Plan and Roadmap, which together aim to better prevent and manage human health and environmental impacts.

With nearly half of methane emissions stemming from a small fraction of sources in the oil & gas industry, we dive into EPA's new Super Emitter Program and how it will impact the industry.

Learn about the recent advancements in PFAS analytical methods including Method 1633 and other recent methods developed to address PFAS in multiple matrices, such as on plastics and in the air.

The EPA's Risk Management Program (RMP) is now finalized. EPA RMP rule amendments include regulatory requirements and deadlines that facilities using hazardous substances need to be aware of.

The US EPA has proposed listing 5 additional PFAS (PFNA, PFHxS, PFDA, PFHxA, PFBA) as Hazardous Constituents under Resource Conservation and Recovery Act (RCRA).

The EPA has published the 2023 Annual Progress Report (2023-APR) to provide updates on the progress made in implementing the Roadmap. In this article, we summarize key points from the 2023-APR, including accomplishments and expectations.

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

We review key changes included in EPA's proposed NSPS Subpart Kc.

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.

On April 19, 2024, the US EPA announced the final designation of two PFAS compounds, PFOA and PFOS, as hazardous substances under CERCLA, also known as Superfund. We cover the rule and its anticipated impacts.

While AFFF products containing PFAS are reliable for firefighting, growing concerns over PFAS in the environment have forced a fresh look into the risk-reward calculation related to AFFF use. Learn more about AFFF and potential alternatives such as fluorine-free foams.
