Docket No. 24-1250-cv

STATE OF VERMONT,

Plaintiff-Appellee,

v.

3M COMPANY,

Defendant-Appellant,

E. I. DU PONT DE NEMOURS AND COMPANY, THE CHEMOURS COMPANY, THE CHEMOURS COMPANY FC, LLC, CORTEVA, INC., DUPONT DE NEMOURS, INC.,

Defendants.

Before:

CABRANES, LOHIER, and SULLIVAN, Circuit Judges.

The State of Vermont sued 3M Company in state court, alleging that 3M’s production of so-called “forever chemicals” contaminated the State’s natural resources. 3M removed the case to federal court under the federal officer removal statute, 28 U.S.C. § 1442(a)(1), asserting a federal defense based on its manufacture of products pursuant to military specifications. The United States

District Court for the District of Vermont (Sessions, J.) remanded the case to state court, finding that removal was untimely under 28 U.S.C. § 1446(b)(3) because 3M filed its notice of removal more than thirty days after receiving correspondence from Vermont that allegedly made the action’s removability ascertainable. We conclude that Vermont’s correspondence did not contain information from which removability under the federal officer removal statute could be ascertained, and therefore that 3M’s notice of removal was timely. VACATED and REMANDED.

MATTHEW F. PAWA, Seeger Weiss LLP, Newton Centre, MA (Laura B. Murphy, Vermont Office of the Attorney General, Montpelier, VT, on the brief), for Plaintiff-

Appellee.

LOHIER, Circuit Judge:

An action “commenced in a State court” is removable to federal court for any number of reasons, including if the action is against a federal officer “for or relating to any act under color of [federal] office” and the federal officer asserts a federal defense. 28 U.S.C. § 1442(a)(1); see Mesa v. California, 489 U.S. 121, 129 (1989). Under 28 U.S.C. § 1446(b)(3), a defendant sued in state court may remove the suit to federal court by filing a notice of removal “within thirty days after receipt . . . of a copy of an amended pleading, motion, order or other paper from which it may first be ascertained that the case is one which is or has become

removable.” The question presented in this case is when the defendant, 3M Company, could first have “ascertained” within the meaning of § 1446(b)(3) that the lawsuit brought against it by the State of Vermont could be removed to federal district court.

Contrary to the District Court’s order, we conclude that the notice of removal in this case was filed within thirty days after it could “first be ascertained” that the case was removable under the federal officer removal statute. We therefore vacate the order and remand for further proceedings.

Vermont sued 3M in state court, alleging that 3M’s production of what have popularly become known as “forever chemicals” had contaminated Vermont’s water, wildlife, soil, and sediment. The two contaminated sites relevant to this appeal are the Rutland City landfill, which Vermont long alleged was contaminated, and 3M’s manufacturing facility in Rutland (the “Rutland facility”).

The lawsuit, filed in 2019, first identified the Rutland City landfill as an allegedly contaminated site in 2021. 3M’s Rutland facility came into the picture in July 2023, when 3M submitted a response to Vermont’s request to identify any

of its facilities within the State that manufactured, used, or stored forever chemicals known as per- and polyfluoroalkyl substances, or “PFAS.” 3M disclosed that “from 1955 to 1975 it, or one of its affiliates, owned a manufacturing facility in Rutland, Vermont at which PFAS-containing products may have been manufactured or otherwise used at some times.” App’x 563–64. The company later produced an undated (though apparently decades old) press release announcing that the Rutland facility created “copper coated laminates, which are used extensively in the manufacture of microwave strip lines for radar antenna pulse transmissions and other applications.” App’x 566. “[U]ntil the early 1970’s,” the press release explained, “microwave industry output was concentrated primarily in military markets.” App’x 566.

Separate from this litigation, by letter dated October 23, 2023, the Vermont Department of Environmental Conservation (“DEC”) notified 3M of its status as a “potentially responsible party” and its obligation “to conduct an environmental investigation at” the Rutland facility. App’x 598. The letter explained that “[w]aste materials from the [Rutland] facility were transported between 1955 and

1975 up to five days per week to the Rutland City [l]andfill, where PFAS has adversely impacted groundwater quality.” 1 App’x 598.

The DEC letter to 3M did not surface in the present litigation until a week later, on November 2, 2023, when Vermont’s counsel in this case emailed a “courtesy copy” of the letter to his counterpart at 3M. The email’s subject line had the caption of the instant case, as follows: “RE: State of Vermont v. 3M Co., et al., No. 547-6-19 Cncv / VTDEC letter.” App’x 597. Neither the email nor the DEC letter referenced 3M’s manufacture of copper-clad laminates at the facility pursuant to a military specification requiring the use of a type of PFAS.

After receiving the DEC letter, 3M broadened its investigation of the Rutland facility. It tracked down former employees, obtained historical

1 The critical paragraph in the DEC letter reads in full as follows:

The Waste Management & Prevention Division (WMPD) of the Vermont Department of Environmental Conservation (DEC) has become aware that 3M Company (“3M”) owned and operated the facility located at 477 Windcrest Road in Noth Clarendon, Vermont from 1955 to 1975, during which time per-and polyfluoroalkyl substances (PFAS) containing products may have been manufactured or used. Waste materials from the facility were transported between 1955 and 1975 up to five days per week to the Rutland City [l]andfill, where PFAS has adversely impacted groundwater quality and has been identified in exceedance of Vermont Groundwater Enforcement Standards.

App’x 598.

specifications for the facility, purchased a copy of a discontinued military specification from a third-party vendor, and reconstructed decades-old operating procedures. Ultimately, 3M was “able to determine that when it owned and operated the Rutland [f]acility, it manufactured (among other products) copper- clad laminates.” App’x 11. The laminates, it also determined, were “produced in accordance with” applicable United States military specification requirements and therefore contained a type of PFAS. App’x 11, 15–16. 3M’s investigation also revealed that scrap material from the manufacture of the laminates containing PFAS was “disposed of as landfill waste,” presumably in the Rutland City landfill. App’x 614.

On December 18, 2023, Vermont effectively confirmed that it sought relief in this litigation related to contamination from PFAS at the Rutland City landfill. And on January 3, 2024 (within a month of completing its investigation and of Vermont’s confirmation), 3M removed this action to federal court under the federal officer removal statute, predicated on its assertion of a colorable federal defense to Vermont’s claims arising from the military specification requirements, pursuant to 28 U.S.C. § 1442(a)(1). See Mesa, 489 U.S. at 129.
