美国环保署（EPA）周二宣布，已与位于蒙大拿州的哥伦比亚瀑布铝业公司（CFAC）就污染清理问题达成协议 [1]。该工厂的所有者嘉能可（Glencore）同意支付 5760 万美元用于缓解数十年来铝冶炼活动造成的环境污染 [1]。根据协议内容，相关方将对包括砷、氟化物和氰化物在内的多种有毒副产物实施遏制处理措施 [1]。
哥伦比亚瀑布铝业公司所在地早在近十年前就被列入国家优先清单（超级基金名单）[1]。此次达成的清理工作预计将在未来两到三年内完成 [1]。该协议目前尚需经过 30 天的公众评论期以及美国蒙大拿地区联邦法院的审查，方可正式生效 [1]。
The U.S. Environmental Protection Agency (EPA) announced on Tuesday that it has reached a cleanup agreement with the Columbia Falls Aluminum Company (CFAC) in Montana [1]. The deal requires CFAC's owner, Glencore, to pay $57.6 million to address decades of pollution from aluminum smelting operations [1]. This site was added to the National Priorities List under the Superfund program nearly 10 years ago [1].
The agreement mandates containment and treatment measures for toxic byproducts including arsenic, fluorides, and cyanide [1]. Before becoming official, the plan must undergo a mandatory public comment period of 30 days followed by review from the U.S. District Court in Montana [1]. Cleanup work is expected to be completed within two to three years [1].
