permissively

adv.许可地；自由地

First, the court interpreted the Clean Air Act permissively: the EPA's mandate to regulate emissions that "will endanger" public health was satisfied if the agency showed a significant risk of harm, not necessarily proof of actual harm. 首先，法院很宽容地解释了《空气洁净法》：如果环境保护署可证明存在很大的"将危害"公众健康的危险，其调整铅添加剂的挥发的命令即符合有关要求，而不必证明实际上的危害。
