Trail Smelter Redux (a.k.a. “Superfund Returns”)

Trail Smelter Redux (a.k.a. “Superfund Returns”)


Kevin earlier today asked about the extraterritorial reach of human rights treaties. But, what about U.S. statutes – how far do they reach? What exactly constitutes an extraterritorial application of U.S. law? On July 6, the Ninth Circuit addressed this issue in Pakootas v. Teck Cominco Metals, Ltd. (see here). The Ninth Circuit ruled that “slag” metal discharges from Teck Cominco’s smelter in Trail, British Columbia, which had traveled down the Columbia River and come to rest within U.S. territory, were subject to regulation under the U.S. Superfund statute – the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 42 USC 9601 et seq. The defendant, Teck Cominco, had argued that applying CERCLA to conduct by a Canadian company in Canada would violate the judicial canon that U.S. statutes do not apply extraterritorially unless Congress makes clear its intent to do so. The Court’s decision, however, avoided this presumption against extraterritoriality entirely; it interpreted CERCLA’s scope, involving a “facility” engaged in the “release” or “threatened release” of hazardous substances, to apply to the actual polluted sites within U.S. territory, notwithstanding that the polluted substances had originated in Canada. As such, the Court reasoned holding Teck Cominco liable under CERCLA constituted a “domestic” — not an “extraterritorial” — application of CERCLA (the court hinted, in any event, that it would have applied CERCLA on the grounds that Teck Cominco’s foreign acts produced “domestic effects” within the United States – a situation that in the past has led U.S. courts to recognize an exception to the presumption against extraterritoriality).

No less than four things fascinate me about this case. First, I love the irony that Teck Cominco’s smelter is the very same smelter that led to the seminal international environmental law decision — the Trail Smelter Arbitration. In that case, the smelter was discharging air pollutants (sulfur dioxide) in Canada that crossed the border and caused damage to U.S. property. The tribunal held Canada liable for the damage caused in the United States by this privately-owned facility. The case is often remembered for establishing liability under international law for transboundary environmental pollution, but it’s often forgotten that the arbitral panel reached its decision by applying international and U.S. law.
