U.S. EPA decision allows for redevelopment at former McClellan Air Force Base
SAN FRANCISCO – Today, the U.S. Environmental Protection Agency announced that a portion of the McClellan Air Force Base Superfund site in Sacramento does not require any additional cleanup. The Agency assessed 46 acres at the former base for shallow soil and soil gas contamination and determined that no further action is needed.
The 35 separate areas included in this decision are located to the east and south of the airfield and were investigated or cleaned up between the late 1990s and 2012. These areas supported aircraft repair, testing, and support facilities; fuel storage and distribution facilities; storage areas; and waste handling and treatment areas. The land is anticipated to be used for industrial and commercial uses.
EPA placed McClellan Air Force Base on the Superfund list in 1987. The 3,452-acre base was closed under the Base Realignment and Closure Act in 1995 and operations ceased in 2001. Through a privatization process begun in 2007, the Air Force is transferring property and cleanup responsibility at the former base to McClellan Business Park LLC, with oversight from EPA and the California Department of Toxic Substances Control and the Central Valley Water Quality Control Board.
Under privatization, the Air Force provides funding to McClellan Business Park to clean up the transferred properties, as needed. The Air Force retains the responsibility for cleanup of contamination in the groundwater and in soils deeper than 15 feet, including low-level radioactive contaminants.
This Record of Decision—which is for the Finding of Suitability for Early Transfer (FOSET) #2 No Further Action Sites—is the fourth to be issued for properties transferred from the Air Force to McClellan Business Park. The decision followed a 30-day public comment period, which was publicized between August and September 2015, and extensive EPA and State review.
