On August 11, 2022, the Los Angeles Regional Water Quality Control Board held a special hearing in which, despite hours of community testimony overwhelmingly opposing it, the Board approved the Memorandum of Understanding (MOU) between itself and Boeing. The MOU is the second part of the deal worked out behind closed doors over the last couple years between the California EPA and Boeing, which also includes the main Agreement between Boeing and the Department of Toxic Substances Control. The deal allows Boeing to walk away from the vast majority of the contamination at the Santa Susana Field Lab, leaving the site not cleaned up and continuing to endanger surrounding communities. The main Agreement had already been approved by DTSC, so the approval of the MOU by the LA Water Board was the final approval needed for the entire deal to take effect.
