Orange County Fire Authority Chief TJ McGovern posted an update this morning about the chemical tanks that are threatening to explode at GKN Aerospace Transparency in Garden Grove. McGovern said that last night the OCFA emergency team has involved subject matter experts. The team found a potential crack in the 7,000 gallon tank that has been pressurizing. That may be relieving some of the pressure that has been building up in that tank.
Today the OCFA emergency team is vetting and validating the information about the possible crack in the tank. This new development could change the OCFA’s trajection and strategy as they work to prevent the tank from exploding.
After initially lifting orders, the Orange County Fire Authority (OCFA) reissued and widened the boundaries into a roughly one-mile buffer zone to protect residents from a potential catastrophic rupture, toxic plume, or explosion. The expansion grew the evacuation zone to encompass an estimated 50,000 to 79,000 residents.
Updated Evacuation Boundaries
The expanded evacuation zone now spans across portions of six different Orange County cities—Garden Grove, Stanton, Anaheim, Cypress, Buena Park, and Westminster—and is generally defined by these major roads:
- North: Ball Road
- South: Trask Avenue
- East: Dale Street
- West: Valley View Street
Note: While the evacuation zone extends slightly south of the 22 Freeway, the highway itself has remained open. Major nearby attractions like Disneyland and Knott’s Berry Farm are outside of the zone and operating normally.
