Effective February 3, 2025, the New Jersey Department of Environmental Protection (NJDEP) adopted amendments to the Ground Water Quality Standards (GWQS), N.J.A.C. 7:9C. The amendments updated the groundwater quality criteria and/or practical quantitation levels (PQLs) for 73 constituents, the vast majority of which became more stringent. For example, groundwater quality standards for tetrachloroethylene (PCE) and vinyl chloride were changed from 1 µg/l to 0.4 µg/l and 0.035 µg/l, respectively. Of note, the decrease attributable to vinyl chloride is by more than an order of magnitude – a significant and regulatorily meaningful change. NJDEP also amended its rounding protocols to round new or revised groundwater standards to two significant figures rather than one. The amendments enable NJDEP to update specific groundwater criteria for constituents with corresponding Safe Drinking Water Act (SDWA) maximum contaminant levels (MCLs) when NJDEP determines the weight of evidence approach would more appropriately address risks posed by such constituents than the health-based levels used to establish MCLs.

SCOTUS Rulings Upend the Administrative Law Landscape
On June 28, in a highly anticipated ruling, the U.S. Supreme Court overturned Chevron USA Inc. v. Natural Resources Defense Council Inc., finding that Chevron deference, the 40-year-old precedent deferring to reasonable agency interpretation of ambiguous statutes, is no longer valid. This decision, in addition to other recent Supreme…
New York’s Spill Reporting Revisions Could Significantly Impact Environmental Due Diligence
In June 2023, the New York State Department of Environmental Conservation (NYSDEC) adopted revisions to its petroleum bulk storage regulations 6 NYCRR Part 613. The amended regulations become effective on October 17.
NYSDEC Sends Letter Outlining Upcoming BCP Submittal Milestones
On July 20, the New York State Department of Environmental Conservation (NYSDEC) sent a letter to Brownfield Cleanup Program (BCP) applicants, consultants, and attorneys that provides an update regarding 2023 Certificate of Completion (COC) milestones and affordable housing deadlines. With respect to BCP submittals, the letter emphasizes the importance of applicants making the submittals necessary to obtain COCs in a timely manner, and warns that failure to do so could result in insufficient time for the NYSDEC to issue COCs by the end of the year. Pursuant to the letter, applicants must meet the following milestones:
EPA Announces Key CCR Policy Amid Alternative Closure Determinations
On January 11, the U.S. Environmental Protection Agency (EPA) issued a new interpretation of its coal combustion residual (CCR) regulations: CCR landfills or surface impoundments “cannot be closed with coal ash in contact with groundwater.” Although EPA claims it has “consistently held” this interpretation, this is the first time EPA has expressly articulated this view. Perhaps acknowledging the novelty of its position, EPA also announced its intent to “review … state-level CCR program applications to ensure they are as protective as federal regulations” and to proceed toward a federal CCR permitting framework.
Environmental Groups Voluntarily Dismiss Their Untimely Challenge to “Part B” CCR Rule Revisions
As previously reported, a coalition of environmental groups recently filed a petition for review in the D.C. Circuit Court of Appeals (D.C. Circuit) challenging the U.S. Environmental Protection Agency’s (EPA) recent final rule titled, “Hazardous and Solid Waste Management System: Disposal of CCR; A Holistic Approach to Closure Part B: Alternate Demonstration for Unlined Surface Impoundments,” 85 Fed. Reg. 72,506 (Nov. 12, 2020). Commonly called “Part B,” the rule allows owners and operators to submit demonstrations showing their clay-lined impoundments are adequately protective of human health and the environment.
Environmental Groups Challenge “Part B” Revisions to CCR Rule
On February 11, three environmental groups — Sierra Club, Alliance for Affordable Energy, and PennEnvironment, Inc. — filed a petition for review in the D.C. Circuit Court of Appeals (D.C. Circuit) challenging the U.S. Environmental Protection Agency’s (EPA) recent final rule titled, “Hazardous and Solid Waste Management System: Disposal of CCR; A Holistic Approach to Closure Part B: Alternate Demonstration for Unlined Surface Impoundments,” 85 Fed. Reg. 72,506 (Nov. 12, 2020). Commonly called “Part B,” the rule allows owners and operators to submit demonstrations showing their clay-lined impoundments are adequately protective of human health and the environment. Part B is the second of two rulemakings comprising EPA’s “Holistic Approach to Closure” amendments to the coal combustion residuals (CCR) rule. Environmental groups filed a similar challenge to the “Part A” rule in the D.C. Circuit in November 2020. That case, Labadie Environmental Organization v. EPA, is currently pending.
California Classifies Solar Panels as Universal Waste
The California Department of Toxic Substances Control (DTSC) recently finalized long-awaited revisions to its hazardous waste regulations that will allow PV solar panels to be managed as “universal waste” beginning on January 1, 2021. This reclassification will have significant implications on how spent PV solar panels are managed in the state.
New Jersey: Permits and Approvals Must Be Registered With NJDEP By October 8, 2020 to Claim PEA 2020 COVID-19 Extension
On July 1, 2020, New Jersey’s Governor Phil Murphy signed the Permit Extension Act of 2020 (“PEA 2020”) into law. The PEA 2020 tolls certain state and local permit approvals, including approvals of soil erosion and sediment control plans granted by a local soil conservation district and waterfront development permits, during the pendency of the public health emergency caused by COVID-19. Additionally, the PEA 2020 extends the deadlines for those approvals that would have otherwise expired during the public health emergency for an additional six months beyond the end of the COVID-19 extension period. Importantly, the PEA 2020 does not impact those approvals that expired prior to March 9, 2020 (the beginning of the public health emergency) or apply to those that will expire after the public health emergency ends.
