CERCLA Claims Against United States and Laguna Pueblo Entities Dismissed In a series of early 2016 decisions issued in Atlantic Richfield Co. v. United States, No. l:15-cv-00056 (D.N.M. filed Jan. 21, 2015), the U.S. District Court for the District of New Mexico dismissed claims for cost recovery and contribution asserted by Atlantic Richfield Co. (ARCO) against the United States, the Laguna Pueblo (Pueblo), and Laguna Construction Company (LCC), a federally chartered tribal corporation formed by the Pueblo. The claims resulting in the decisions arose from U.S. Environmental Protection Agency (EPA) investigations into inadequate remediation efforts undertaken decades ago at the Jackpile Paguate uranium mine in the Grants Uranium Belt in west-central New Mexico.
