This bill establishes new requirements for companies seeking to build large data centers on federal public lands. The legislation classifies such projects as major federal actions requiring full environmental review under existing environmental law, which eliminates a streamlined approval process previously available. Data center developers must now provide the public with at least 45 days to comment on environmental studies and hold at least one public hearing in affected communities. The bill also requires detailed analysis of water consumption for electricity generation and cooling systems over a ten-year period, along with assessment of impacts on regional water supplies and drought resilience. Additionally, companies must submit workforce plans documenting job creation projections, the number of local workers hired, whether prevailing wages will be paid, and long-term employment expectations over a twenty-year period.
