It consists of areas extending approximately 2,000 ft on both sides of an approximately 9-mile stretch of the power line and maintenance road. The power line and maintenance road are located in and between areas of the Rice Valley Sand Dunes and the West Riverside, Riverside, and Big Maria Mountains. The power line and maintenance road were accessed by a dirt road from California Highway 62. There was no information available concerning disposal of the site. However, current information indicates that the site is owned and maintained by the Department of Interior. This property is known or suspected to contain military munitions and explosives of concern (e.g., unexploded ordnance) and therefore may present an explosive hazard (Source: U.S. Army Corps of Engineers) « see less

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
