LOS ANGELES, CA (July 27 2021)— We appreciate the opportunity to respond to the County’s report. In fact, we are already working with the various County departments to address the findings of the report and improve public notifications.
In terms of public notification, as required under our permit to operate the Hyperion Water Reclamation Plant, we notified the State Office of Emergency Services in just over an hour of the emergency discharge, and they in turn notified the other public agencies. A County Department of Public Health inspector was on-site (not indoors) almost immediately and saw for herself the severity of the exterior overflow situation while the discharge was occurring.
Beyond the findings of this report, however, LASAN has been conducting an internal investigation into the cause and source, in keeping with our mission to constantly improve and serve as effective environmental stewards.
Finally, as long-standing El Segundo community partners, and in an effort to mitigate the impacts experienced by residents, LA Sanitation & Environment is extending its Hyperion reimbursement program for some costs incurred by residents in seeking relief from the odors remaining from the flooding at the plant. The details of the extended program can be found on our website at:
