To seek cost contribution in a cleanup action, First Environment evaluated the historical operations on certain parcels of the former Lockheed Air Terminal, now known as Bob Hope Airport or Burbank-Glendale-Pasadena Airport. Based on its work in the late 1990s and thereafter in defense of Lockheed in a mass toxic tort case (Hook et al. v Lockheed 2:96-cv-05584) First Environment’s evaluation reviewed history from the Government’s acquisition of undeveloped land during WWII to Government and private sector uses through 2010. Activities conducted on the subject parcels in the WWII era included construction of some 74 structures for use as an Air Defense Unit, operation of a training school for U.S. Army Air Force (USAAF) ground crews, and research and development of top-secret aircraft projects.
First Environment had previously used its engineering expertise in evaluating process wastes associated with aircraft manufacturing and maintenance operations to determine the sources of groundwater and soil contamination at the site. This expertise included the evaluation of vapor and cold degreasing operations where aircraft parts were cleaned with solvents, including trichloroethylene and perchloroethylene, as part of routine maintenance operations and/or prior to plating, welding, assembly or painting of the aircraft parts. In this more recent project, First Environment investigated the industrial history of properties in the vicinity of the parcels of interest, combining newly acquired information with previously obtained information to perform analysis. First Environment looked at historical waste generating operations as well as aviation fuel and waste incineration in fire pits at an on-site fire training facility. First Environment also compiled a military history of the subject parcels and established waste disposal operations for the entities that occupied the parcels and nearby areas from World War II until 1960, when the majority of military operations ceased.
