There are government agencies who are also involved in overseeing what happened at Hyperion.
The South Coast Air Quality Management District (AQMD) is the law enforcement agency that issues tickets to polluters who create dangerous and noxious odors. AQMD held a hearing on its investigation of Hyperion on September 6, 2022, at 9:00 a.m. If you missed the live hearing, you can re-watch it on AQMD’s YouTube Page: https://www.youtube.com/watch?v=pZ3KsW9HNus
- The AQMD agenda can be found here: Hearing Board Case Documents (aqmd.gov).
- A brief history of AQMD’s actions against LA Sanitation. AQMD issued at least 47 notices of violation and reportedly issued another notice of violation. See: http://www.aqmd.gov/home/news-events/community-investigations/hyperion-water-reclamation-plant. We requested copies of those notices but thus far, AQMD is treating the LA Sanitation’s release of noxious gas odors as an ongoing investigation.
- By comparison: the AQMD issued only one notice of violation against SoCalGas when its gas leaked in the North San Fernando Valley, though the notice covered multiple weeks: http://www.aqmd.gov/home/news-events/community-investigations/aliso-canyon-update/compliance-enforcement-actions-new/notice-of-violation.
