On June 15, 2022, the United States Environmental Protection Agency (EPA) released drinking water health advisories [1] for certain per- and polyfluoroalkyl substances (PFAS), resulting in the establishment of:

  1. Near zero updated interim advisory levels for Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonic acid (PFOS) that are not only orders of magnitude below previously established levels, but that are also below detectable levels and, notably, were issued in advance of completion of peer review by EPA’s Science Advisory Board (SAB); and
  2. Newly issued final advisories at low levels for GenX and PFBS chemicals that have been used as replacement chemicals for PFOA and PFOS.

Prompted by several emergency events, as previously reported, on June 1, 2022, the Texas Commission on Environmental Quality (TCEQ) adopted revisions to the compliance history rules to authorize the executive director to reclassify a site’s compliance history if an “exigent circumstance” exists. An exigent circumstance is defined as: i) a significant disruption to one or more local communities; ii) a significant commitment of emergency response resources by a federal or state authority to address an actual unauthorized release of pollutants, contamination, or other materials regulated by the agency; and iii) a significant event the commission determined must be urgently accounted for in the site’s compliance history.

On May 3, 2022, the Railroad Commission of Texas (Railroad Commission) voted to approve three actions that represent a major step forward in facilitating the deployment of carbon capture, use and sequestration activities (CCUS) in Texas. Specifically, the Railroad Commission approved:

  • Publication of proposed amendments to its rules implementing the state program for geologic storage of anthropogenic CO2 and incorporating federal requirements;
  • Submittal to the US Environmental Protection Agency (EPA) of a pre-application to gain regulatory authority over Class VI underground injection control (UIC) wells that are used for injection of CO2 into deep subsurface formations; and
  • A request that the Governor formally ask EPA for Class VI UIC well program approval. [i]

On December 15, 2021, the Texas Commission on Environmental Quality (TCEQ) approved the publication of proposed changes to its compliance history rules to allow the agency to reclassify a site’s compliance history classification if an emergency incident results in significant impacts to the public and the environment.[1] In describing the background and reasons for the rulemaking, the agency noted the occurrence of a number of emergency incidents at industrial facilities in the state and resulting scrutiny of the facilities involved in those incidents.

11.22.21 Last week, EPA transmitted four important documents to the EPA Science Advisory Board (SAB) for peer review that included updated health assessments for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). This peer review, which will start on December 16, will inform EPA’s development of a Maximum Contaminant Level (MCL) Goal and a future, legally enforceable National Primary Drinking Water Regulation for PFOA and PFOS under the Safe Drinking Water Act. As noted in the PFAS Strategic Roadmap: EPA’s Commitments to Action 2021-2024, EPA intends to release a proposed drinking water regulation for PFOA and PFOS in fall 2022. These scientific documents will provide the underpinnings for that important regulation.

 On October 18, 2021, the US Environmental Protection Agency launched its PFAS Strategic Roadmap: EPA’s Commitments to Action 2021-2024 (“Roadmap”)[i] setting forth its “whole-of-agency” approach to address per- and polyfluoroalkyl substances (PFAS). The Roadmap sets forth timeframes for EPA actions to address PFAS across environmental media and under various statutory authorities including the Toxic Substances Control Act (TSCA), Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Safe Drinking Water Act (SDWA), Clean Water Act (CWA) and Clean Air Act (CAA). As such, EPA’s implementation of the Roadmap, including key initiatives rolled out in the days following its release, will affect a broad spectrum of industry sectors and facilities throughout the PFAS lifecycle who may face new and expanded regulatory requirements and obligations.

On January 15, 2021, the Texas Commission on Environmental Quality (“TCEQ”) received approval to implement the National Pollutant Discharge Elimination System (“NPDES”) program for oil and gas discharges. [1]  Generally, as a result of this approval, applicants for NPDES permits for produced water, hydrostatic test water, and gas plant effluent will only require a single TCEQ authorization rather than authorizations from both the Railroad Commission of Texas (“RRC”) and the U.S. Environmental Protection Agency (EPA) as previously had been required. [2]

On November 27, 2020, the US Environmental Protection Agency (“EPA”) published notice that the Texas Commission on Environmental Quality (“TCEQ”) has applied to the US EPA for National Pollutant Discharge Elimination System (“NPDES”) program authorization for discharges of produced water, hydrostatic test water and gas plant effluent. [1] TCEQ’s application (“Application”) was filed in response to a bill passed during the last Texas legislative session that required TCEQ to submit to EPA no later than September 1, 2021, a request for NPDES permitting authority for discharges of produced water, hydrostatic test water and gas plant effluent associated with oil and gas activities currently under the jurisdiction of the Railroad Commission of Texas (RRC). [2] Under this legislation, state authority to regulate these discharges will transfer from the RRC to TCEQ upon EPA’s grant of NPDES permitting authority to TCEQ. Should EPA grant NPDES permitting authority to TCEQ for these discharges, a prospective permittee would generally only need to obtain a single TCEQ authorization (rather than an authorization from both the RRC and EPA).

Last month, the Texas Commission on Environmental Quality (“TCEQ”) launched a temporary “Find It and Fix It” program effective through January 31, 2021 to facilitate air quality compliance for companies with oil and gas operations in the Permian Basin.  Regulated entities that comply with the requirements of the temporary program may be eligible for enforcement discretion.
