Lockheed Martin tested rocket motors and solid rocket propellant in five areas of operation at the site. Initial cleanup activities began at the site in 1984 when Polychlorinated Biphenyl-contaminated asphalt and associated sand and gravel were removed.
Ten years later Lockheed Martin removed more than 800 tons of waste from the Garbage Disposal Area. In 2003 the corporation began extensive investigations and evaluations at the site. Based on its investigations, Lockheed Martin submitted a Remedial Action Plan (RAP) to the California Department of Toxic Substance Control (DTSC) in 2014. Public review of the Laborde Canyon RAP occurred in 2016; and DTSC approved the RAP in 2016. For more information view the Laborde Canyon Fact Sheet.
