DOE prepared an EA (DOE/EA-2025) to analyze a proposal to develop land that comprises the Pacific Northwest National Laboratory (PNNL) Campus, in Richland, Washington. The development of this land would allow PNNL to meet its current and anticipated future research and development needs. PNNL proposes to construct, operate, demolish, lease, sell, or donate facilities and properties in support of PNNL needs. Facilities are likely to include, but not limited to, research laboratories, office space, support buildings, emergency services, and associated infrastructure.
