In State of Louisiana et al. v. U.S. Envt’l Prot. Agency et al., 2:23-CV-01714, 2024 WL 994651 (W.D. La. Mar. 7, 2024), a federal judge rejected certain states’ and industry groups’ motion for preliminary relief to enjoin the EPA’s revised Clean Water Act (“CWA”) rule (“2023 Rule”). The 2023 Rule reinstated EPA’s long-held interpretation of Section 401 of the CWA that afforded states and tribes broad authority to veto or impose conditions on federally permitted activities due to water quality concerns. The court’s decision is a blow to efforts instituted by EPA under the Trump administration to interpret the authority of states and tribes more narrowly under Section 401. Read More »

In California Restaurant Association v. City of Berkeley, 89 F. 4th 1094 (9th Cir. 2024), the Ninth Circuit was tasked with determining whether the City of Berkeley’s attempt to prohibit the use of natural gas pipelines in new buildings through a local ordinance conflicted with the federal Energy Policy and Conservation Act (“EPCA”), 42 U.S.C. § 6297(c).  That statute expressly preempts state and local governments from enacting regulations restricting energy use of many natural gas appliances, including those used in household and restaurant kitchens.  After evaluating the parties’ arguments, the court concluded that the ordinance is preempted by the EPCA based on the text, structure, and context of that statute.  Read More »

On January 3, 2024, the United States Court of Appeals for the Tenth Circuit reversed a district court decision that held that a Colorado gold mining company’s operation of four settling ponds constituted an unpermitted discharge of pollutants into navigable waters under the Clean Water Act (“CWA”).  In Stone v. High Mountain Mining Company, No. 22-1340 (10th Cir. 2024), the Tenth Circuit held that the district court did not correctly follow the Supreme Court’s decision in County of Maui v. Hawaii, 140 S. Ct. 1462 (2020) regarding the CWA’s applicability to indirect discharges to navigable waters. Read More »

On January 2, 2024, the United States District Court for the Eastern District of Michigan issued an order to exclude the expert testimony of Dr. Robert Michaels in a series of cases related to the corrosive water in Flint, Michigan. Carthan, et al. v. Snyder et al, No. 5:16-cv-1044 (E.D. Mich. 2024). The court held that Dr. Michaels, in applying a methodology commonly employed by epidemiologists known as the Bradford Hill guidelines, failed to establish an association between corrosive water and skin and hair conditions, and without such, the testimony was unreliable and could not be used to infer causation between Flint water and reported skin rashes and hair loss.  Read More »
