The U.S. Environmental Protection Agency (EPA) this week added five PFAS chemicals for a total of six PFAS chemicals to a list of risk-based values. EPA uses these values to determine if response or remediation activities are needed. The five PFAS additions include: hexafluoropropylene oxide dimer acid and its ammonium salt (HFPO-DA — sometimes referred to as GenX chemicals), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorohexanesulfonic acid (PFHxS). EPA added the first PFAS substance, perfluorobutanesulfonic acid (PFBS), to the Regional Screening Level (RSL) and Regional Removal Management Level (RML) lists in 2014 and updated it in 2021 when EPA released its updated toxicity assessment for PFBS.

Tracy Mehan joins Dave Ross and Anna Wildeman to discuss his work as executive director of government affairs with the American Water Works Association and the flood of water topics inundating the drinking water sector, including new infrastructure funding, affordability as an environmental justice issue, AWWA’s perspective on PFAS and its associated superfund liability question, and updates to the lead and copper rule.

In a move consistent with EPA’s recent uptick in oversight of state regulatory programs, EPA has proposed to establish federal water quality standards (WQS) for human health criteria (HHC) for Washington state. The proposal comes less than two months after the Office of Water rescinded a memorandum that directed EPA regions to comply with Clean Water Act statutory deadlines and give sufficient deference to technical determinations made by states that administer EPA-approved delegated Clean Water Act programs. While the proposal itself is not surprising — EPA telegraphed that it would take this action early in this administration — the timing of the proposal is somewhat surprising.

On April 3, representatives of the hydropower industry, Native American tribes, and conservation organizations provided a package of proposed legislative reforms to the Federal Power Act (FPA) to the ranking members of the U.S. Senate’s Energy and Natural Resources Committee and the U.S. House of Representatives’ Energy and Commerce Committee. The package, which was developed as part of the Stanford University Uncommon Dialogue on hydropower and river conservation, is the result of year-long intense negotiations between a variety of hydropower stakeholders.

The Securities and Exchange Commission (SEC or Commission) published proposed rules on March 21 that, for the first time, would codify the Commission’s expectations regarding what kinds of climate-related disclosures public companies must make in their required filings to the SEC. Prior to now, companies have had to rely on 2010 guidance from the Commission to determine what information they should disclose to investors regarding their climate-related risks.

In a proposed rule signed on February 28, but not yet published in the Federal Register, EPA proposed to significantly expand its current approach to regulating the interstate transport of ozone. Under the so-called “good neighbor” provision of the Clean Air Act, states are required to submit State Implementation Plans (SIPs) to EPA containing rules sufficient to prohibit emissions from their state that would either significantly contribute to another state’s nonattainment of national ambient air quality standards or interfere with another state’s maintenance of those standards. If a state submits a SIP that is insufficient to satisfy its good neighbor obligation, EPA must issue a Federal Implementation Plan (FIP) to fully address the problem.

The listing status of the northern long-eared bat (NLEB) under the Endangered Species Act (ESA) has been the subject of litigation since the U.S. Fish and Wildlife Service (Service) originally listed it as threatened in 2015. At that time, the Service also issued an ESA Section 4(d) rule that allowed incidental take resulting from development activities to occur within its range and habitat where white nose syndrome (WNS) was not present, so long as certain best management practices, such as time of year restrictions on tree removal, were followed. In 2021, the U.S. Court of Appeals for the D.C. Circuit found that the Service’s 2015 listing decision did not adequately explain why the bat was not listed as endangered, and failed to address how impacts, such as habitat modification allowed under the 4(d) rule, affected the NLEB. The court remanded the 2015 rule to the Service for further consideration, but allowed the threatened listing and 4(d) rule to stay in place while the Service reconsidered the listing status for the species.

WateReuse Association Executive Director Pat Sinicropi joins Anna Wildeman and Dave Ross to talk about the role of water reuse as a water management strategy for the 21st century. Specifically, Pat discusses water reuse technology, the role of the federal government in encouraging water recycling as a national strategy, and state and local community efforts to accelerate the adoption of water reuse in businesses and communities across the country.

On February 16, the White House Council on Environmental Quality (CEQ) published in the Federal Register new interim guidance that is intended to facilitate the review and deployment of carbon capture, sequestration, utilization, and storage (CCUS) technologies. For those hoping for specific guidance that would accelerate the deployment of CCUS, the interim guidance is likely to disappoint. Congress recently signaled strong interest in accelerating CCUS as a national decarbonization strategy by providing billions of dollars of new investment to support the industry, but the guidance is largely silent on how the executive branch will match the urgency in ensuring on-the-ground deployment in the foreseeable future. Comments on CEQ’s guidance are due to CEQ by March 18. Continue Reading Carbon Capture Utilization and Storage: Administration Action (and Inaction)
