## Summary

**Centralized e-NEPA portal and interoperable digital twins** would modernize NEPA reviews for Department of Transportation-led infrastructure projects to speed permitting, improve public access, and coordinate agencies. The bill focuses on digital tools, a standardized portal, and tighter interagency workflows to cut review time and surface project impacts visually. - Communities and the public would get online access to nonsensitive project documents, timelines, and a public comment channel through the e-NEPA portal to follow and weigh in on projects. - Project sponsors and infrastructure teams would face a digital-twin pilot within 120 days covering at least 10 projects, with a Congress report in 2 years to measure permitting time, cost, and collaboration benefits. - Federal agencies and DOT leadership would adopt technical standards and guidance, with digital-twin guidelines due within 18 months, portal creation within 2 years, mandatory portal use by Jan. 1, 2028, and a requirement to cut eligible NEPA review timelines by not less than 25 percent.
