Yesterday, the US Environmental Protection Agency (EPA) and the US Army Corps of Engineers (Corps) (together, the Agencies) published a final rule revising the definition of “waters of the United States” (WOTUS) subject to federal regulation and permitting requirements under the Clean Water Act (CWA). This rule is the latest attempt by the Agencies to craft a durable rule defining WOTUS. The new rule, which largely mirrors the 2021 proposal, asserts a broader geographic scope of federal jurisdiction than the 2020 Navigable Waters Protection Rule (NWPR). In particular, the Agencies adopt the broadest possible interpretation of the Supreme Court’s decision in Rapanos (through incorporation of both the plurality’s “relatively permanent” test and Justice Kennedy’s “significant nexus” test). The final rule would, for the first time, codify aspects of the Agencies’ 2008 Rapanos Guidance and would rely on the significant nexus test’s case-by-case approach for evaluating jurisdiction for tributaries, wetlands, and other waters. The Agencies released the final rule while the Supreme Court considers the scope of CWA authority over a major category of WOTUS, “adjacent wetlands,” in Sackett v. EPA, and the Supreme Court could hand down a decision in the coming months that could require changes to the rule.
TCEQ Requests Public Input on Draft Wastewater Regionalization Guidance
The Texas Commission on Environmental Quality is inviting informal public comment on the draft Regulatory Guidance Document for Evaluation of Regionalization for Potential New Wastewater Systems. TCEQ is required to implement a policy to “encourage and promote the development and use of regional and area-wide waste collection, treatment and disposal systems to serve the waste disposal needs of the citizens of the state and to prevent pollution and maintain and enhance the quality of the water in the state.”

Fourth Circuit Ruling Narrowly Construes Administrative Enforcement Bar to Clean Water Act Citizen Suit
A recent Fourth Circuit decision narrowly construed the state administrative enforcement bar to the Clean Water Act citizen suit, allowing a citizen suit seeking civil penalties to proceed despite the fact the state had already issued a notice of violation for the same alleged conduct.

EPA Issues Near Zero Drinking Water Health Advisories for Certain PFAS
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:
- 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
- Newly issued final advisories at low levels for GenX and PFBS chemicals that have been used as replacement chemicals for PFOA and PFOS.

Federal Court Finds Tort Claims Preempted by CERCLA Consent Decree
A recent federal district court decision shows how a consent decree can provide protection to responsible parties under CERCLA by precluding later-filed tort claims seeking additional relief or different remedial action.

California Proposition 65: OEHHA Publishes Second Modification to Proposed Rules to Short-Form Warnings
On April 5, 2022, the California Office of Environmental Health Hazard Assessment (OEHHA) published a second 15-day notice of modification to its proposed Proposition 65 safe harbor “short-form” warning regulations. If adopted, the amendments would significantly impact businesses’ use of the short-form warnings.

California on Path (Again) toward Regulating Hexavalent Chromium (Chromium-6) in Drinking Water; Follows EPA Scientific Workshop in September 2021
On April 5 and 7, 2022, the State Water Resources Control Board (Board) will be holding public workshops to present information and solicit public input regarding a proposed administrative draft of a hexavalent chromium (chromium-6) maximum contaminant level (MCL). MCLs are drinking water standards with which public water systems must comply. The workshops, and administrative draft of the MCL, will help inform the Board’s formal rulemaking, expected to begin later this year. If adopted, the MCL would be the first drinking water standard for chromium-6 in the nation. [1]

California and the World Move Toward Cleaning Up Microplastics: What You Need to Know Now
Late last month, California adopted a first-in-the nation strategy to address microplastics in the environment. Shortly thereafter, on March 2, 2022, the United Nations Environment Assembly adopted a resolution setting up a path to a global treaty to end plastic pollution. And, after adopting the world’s first regulatory definition of “microplastics in drinking water” in 2020, California anticipates additional action addressing microplastics in drinking water as early as this month.

Fifth Circuit Endorses Broad Reading of “Removal” Under CERCLA To Bar RCRA Citizen Suit
Last week, in Residents of Gordon Plaza, Inc. v. Cantrell, the Fifth Circuit denied a petition for rehearing en banc of a recent decision affirming the dismissal of a Resource Conservation and Recovery Act (RCRA) citizen suit. The key issue in the underlying appeal, 25 F.4th 288 (5th Cir. 2022), was whether certain maintenance activities qualify as a “removal” action under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The court affirmed that the maintenance activities do indeed constitute a “removal action.” Therefore, the suit was barred under 42 U.S.C. § 6972(b)(2)(B)(iv), which precludes RCRA citizen suits where a “responsible party is diligently conducting a removal action” pursuant to a CERCLA consent decree with EPA.

Biden Administration Rolls Out New Climate, Economic, and Environmental Justice Tools
Two recent actions by the Biden Administration will identify areas of focus for environmental justice and therefore influence environmental enforcement priorities, federal permitting and licensing, and federal spending, among other actions. On February 18, the White House Council on Environmental Quality released the beta (or draft) version of its Climate and Economic Justice Screening Tool (CEJST), a key component of President Biden’s Justice40 Initiative. The Justice40 Initiative set the goal of “delivering 40 percent of the overall benefits of relevant federal investments” to disadvantaged communities. The CEJST serves a specific purpose: to help agencies identify disadvantaged communities in order to direct federal benefits and help agencies measure whether 40 percent of benefits are being received by those communities.
