Tour Dates and Times.

1. Livermore Lab Site 300 (Tracy)
The tour is: Thursday, April 25 from 9 a.m. to 12 p.m.

Site 300 was established to conduct open-air bomb tests with toxic and radioactive materials. Current operations allow for contained tests and open-air detonations; high explosives R&D, machining and manufacturing; and waste burning and storage. Site 300 was placed on the EPA’s Superfund list of most contaminated locations in the country in 1990. The tour will include views of unlined toxic and radioactive waste pits and at least one open-air “firing table” as well as some of the groundwater remediation equipment in use.

2. Livermore Lab Main Site (Livermore)
The tour is: Tuesday, April 30 from 1 p.m. to 4 p.m.

The Main Site contains most of the Lab’s principal nuclear weapons development facilities, including the plutonium facility and vaults, hardened engineering test building, tritium facility, radiography facility, high explosives application facility, National Ignition Facility, and others. The Main Site was placed on the EPA Superfund list in 1987. The tour will visit groundwater treatment facilities, including several areas where new technologies for remediating soils and water are being tested.
