EPA说,《清洁空气法》的规则只适用于实际排放单位,而不是非排放建筑,加速数据中心和芯片厂等项目。 The EPA says Clean Air Act rules only apply to actual emission units, not non-emitting construction, speeding up projects like data centers and chip plants.

环保局澄清说,《清洁空气法》开工前规则只适用于实际排放单位的工作,而不适用于基金会或墙壁等非排放性基础设施,允许数据中心和半导体厂等项目提前开始与排放无关的建设。 The EPA has clarified that Clean Air Act preconstruction rules apply only to work on actual emission units, not non-emitting infrastructure like foundations or walls, allowing projects such as data centers and semiconductor plants to begin non-emissions-related construction earlier. 这一变化立即通过2025年9月致亚利桑那热带金枪鱼监测中心的信函生效,解决了长期存在的不确定性,并旨在减少延误和费用。 This change, effective immediately via a September 2025 letter to TSMC Arizona, resolves long-standing uncertainty and aims to reduce delays and costs. 该机构计划在2026年底完成一项规则制定工作,正式编纂“从实际建设开始,”这一较狭义的定义,确保一致性,防止今后出现逆转。 The agency plans to finalize a rulemaking by late 2026 to formally codify the narrower definition of “begin actual construction,” ensuring consistency and preventing future reversals. 在此之前,环保局将提供个案指导。 Until then, the EPA will provide case-by-case guidance. 虽然早期施工仍然处于开发商的风险之中 -- -- 潜在的许可证条件可能需要改变或拆除 -- -- 更新预计会精简项目时间表,同时不会削弱环境监督。 While early construction remains at the developer’s risk—potential permit conditions could require changes or demolition—the update is expected to streamline project timelines without weakening environmental oversight.
