In February 2014, PEER attorneys asked the school district to assess the Malibu High School campus. In July 2014, the U.S. Army Corps of Engineers wrote that Malibu High school had never been a military site, despite published reports and interviews with long-time residents present during those years that Malibu did serve as a World War II military training center. The school district hired an environmental firm named Environ, whose initial clean up plan was criticized for allowing elevated PCB levels to remain inside classrooms for 15 years or more, for not testing caulk in all rooms built prior to 1979 and for air quality monitoring of only one year. In April 2014, the EPA rejected the clean up plan. In July 2014, Environ released a second PCB clean up plan. Two weeks later PEER published PCB test results of June 2014 caulking and dirt samples from school rooms, not previously tested by the District, "at thousands of times the levels previously released to the public".
