Supplemental Information Report in Response to the August 18, 2011 Application by Idaho, Oregon, and Washington for Lethal Removal Authority under Section 120 of the Marine Mammal Protection Act

On March 14, 2008, we, the National Marine Fisheries Service (NMFS), issued a final environmental assessment (EA) and finding of no significant impact (FONSI) pursuant to the National Environmental Policy Act (NEPA) supporting our decision to authorize the states of Idaho, Oregon, and Washington (states) to lethally remove certain California sea lions to reduce pinniped predation on Endangered Species Act (ESA) listed salmon and steelhead (salmonids) below Bonneville Dam in the lower Columbia River. On November 23, 2010, the Ninth Circuit Court of Appeals instructed the district court of Oregon to vacate NMFS’ authorization and remand the decision to NMFS for further explanation.

2008年3月14日，美国国家海洋和渔业局（National Marine Fisheries Service, NMFS）依据《国家环境政策法》（National Environmental Policy Act, NEPA）发布最终环境评估（Environmental Assessment, EA）及无重大影响认定（Finding of No Significant Impact, FONSI），以支持其作出的授权决定：准许爱达荷州、俄勒冈州与华盛顿州（下称“三州”）对部分加州海狮实施致命移除，以减少哥伦比亚河下游邦纳维尔水坝下游区域内，鳍足类动物对受《濒危物种法》（Endangered Species Act, ESA）保护的鲑鱼及钢头鳟（鲑科鱼类）的捕食行为。2010年11月23日，美国第九巡回上诉法院指示俄勒冈州地区法院撤销NMFS此前的授权决定，并将该案发回NMFS，要求其进一步作出解释说明。
