Overview
- Crews will begin work Monday to remove neutralized methyl methacrylate from two of three tanks at the Garden Grove site using specially outfitted, temperature‑controlled containers and phased safety protocols.
- Officials say air and odor monitoring will run continuously during daylight operations and that an online dashboard will let residents view real‑time data from mobile and fixed monitors around the facility.
- Authorities warn residents they may notice a temporary fruity smell because MMA has a very low odor threshold but say measured concentrations will remain below levels associated with health concerns.
- The drainage was originally set for June 4 but was delayed because sealed transport and other specialized resources were unavailable, and federal and local probes continue after recent FBI and EPA evidence seizures and an Orange County DA inquiry.
- About 50,000 people were evacuated in late May after an overheated, cracked tank raised explosion fears; GKN faces multiple class‑action suits and has pledged community aid amid ongoing disputes over the amount and local trust.
