Executive Order 13807, signed on August 15, 2017, fundamentally restructured how federal agencies review and approve infrastructure projects by compressing environmental review timelines from a typical ten-year process to a mandatory two-year maximum. The order, titled "Establishing Discipline and Accountability in the Environmental Review and Permitting Process for Infrastructure Projects," applied to major infrastructure categories including highways, pipelines, bridges, water systems, and energy facilities. The executive order did not merely accelerate existing procedures—it removed specific environmental review requirements and created a hard deadline that agencies were required to meet, shifting the regulatory burden away from comprehensive environmental assessment toward expedited approval.

The direct consequences affected hundreds of infrastructure permit applicants immediately. Pipeline developers, highway construction companies, and energy infrastructure firms that filed permits after the order's effective date experienced dramatically shortened review periods. Federal agencies, particularly the Environmental Protection Agency and the Army Corps of Engineers, faced institutional pressure to complete environmental impact statements and permitting decisions within the compressed timeline, effectively reducing the depth and scope of environmental analysis that typically accompanies such projects.

This 2017 order established the procedural foundation for the broader anti-environmental regulatory pattern that would intensify throughout subsequent administrations. The streamlined permitting framework directly enabled the later invocation of the Defense Production Act for fossil fuel acceleration in 2026, which specifically cited reduced environmental review as a mechanism for expanding oil and coal extraction. Similarly, the expedited infrastructure permitting process created the administrative pathway for projects like the Minnesota mining operations that faced fewer cumulative environmental obstacles. Combined with the EPA's subsequent rescission of environmental protections and standards, the original two-year permitting ceiling transformed from a process reform into a systematic barrier against comprehensive environmental oversight.

Reversal would require both executive action to restore the ten-year review standard and congressional action to reinstate environmental review requirements that the original order eliminated. Such reversal would restore agencies' capacity to conduct thorough environmental impact assessments before approving major infrastructure projects.
