La Habra Chemical Leak Contained, Cause Still Unknown, Weeks After $100 Million Fund Set Up for Earlier Orange County Incident

A chemical tank leak in La Habra, California sent an orange haze drifting over a mixed residential and industrial neighborhood on Tuesday, September 8, prompting a shelter-in-place order and school evacuation before crews shut it down within hours.

Los Angeles County Fire Capt. Aaron Katon told the Associated Press that crews responded to a business that makes cleaning products after a call came in shortly before noon reporting the cloud. Police evacuated a nearby middle school as a precaution, Katon said.

The company involved is Shepard Bros., according to the Associated Press. Shepard Bros. could not immediately be reached for comment.

Three company employees reported minor respiratory irritation and declined further treatment, Katon said. Los Angeles County Fire Department spokesperson Kaitlyn Aldana said three people on scene overall declined transport to a hospital.

Authorities still don't know what the chemical was. Katon said all shelter-in-place orders were lifted by Tuesday afternoon. The South Coast Air Quality Management District deployed staff to investigate, spokesperson Connie Villanueva said.

La Habra Mayor Jose Medrano had urged residents to shelter in place earlier in the day and said some streets were being evacuated. The area sits about 10 miles north of Anaheim, a mix of homes and industrial warehouses.

Witnesses described the cloud as dark yellow rather than solid orange. Keary Godinez, a 20-year-old who works at a nearby restaurant, told the Associated Press it "looked like pollen dust" and that she didn't detect any smell. She said she watched students board buses to evacuate while police told her the restaurant could stay open. Luis Gomez, who manages a nearby pickleball program, said he called police after seeing the cloud and was told anyone within a mile of the site was under an evacuation order.

Same Region, Different Company, Bigger Bill

This is not the first time in 2026 that Orange County-area residents have had to evacuate over an unexplained chemical release. On May 21, a threatened explosion or leak at a tank owned by GKN Aerospace Transparency Systems Inc., a British-based multinational, forced evacuation orders in Garden Grove, roughly 26 miles southeast of Los Angeles. Those orders stayed in effect for five days, according to the Orange County District Attorney's office.

That earlier incident was serious enough that the Orange County DA's office announced on August 24 a $100 million claims program to reimburse more than 50,000 residents and businesses that evacuated, covering hotel stays, lost wages, and per diem expenses. District Attorney Todd Spitzer is negotiating a civil disposition with GKN that would also require the company to adopt an enhanced safety plan with independent monitoring, on top of separately discussed reimbursement for first responders and possible civil penalties.

GKN Aerospace Senior Vice President Steve Carlin apologized to Garden Grove's city council in June, saying: "On behalf of GKN and the Garden Grove plant, I want to say I'm sorry this event ... occurred." GKN has said its environmental response partner, Arcwood Environmental, completed key cleanup actions. The Epoch Times reported it reached out to GKN Aerospace for comment on the compensation program but received no response by publication.

The La Habra leak and the Garden Grove incident are unrelated. Different company, different tank, different chemical, three months apart. Both fall inside the same stretch of industrial-adjacent Southern California neighborhoods where residents have now twice this year had to evacuate or shelter in place without immediately knowing what was in the air.

The Fair Question Here

Residents and local officials have a legitimate complaint: authorities still can't say what chemical leaked in La Habra, and it took months of negotiation before Orange County secured the GKN reimbursement deal for the May incident. A skeptic could reasonably ask whether facilities storing hazardous chemicals near homes and schools face enough routine inspection before something goes wrong, not just compensation after.

Nothing in the record from either incident points to regulators looking the other way. The South Coast Air Quality Management District deployed investigators the same day as the La Habra leak, and the Orange County DA's office moved to secure a nine-figure compensation fund and safety-plan commitment from GKN within roughly three months of the Garden Grove evacuation. No charges have been filed in either case, and no investigation has concluded on what caused the La Habra leak.

Early wire dispatches from the Independent, ABC News, and MyNorthwest carried only the bare outline Tuesday afternoon, before the company's name and the middle school evacuation were confirmed. Fuller Associated Press reporting from Los Angeles and Santa Ana filled in those details by evening.

What the tank actually contained in La Habra remains unknown, and whether Shepard Bros. faces the kind of scrutiny GKN Aerospace is now under is an open question. The South Coast Air Quality Management District's investigation is ongoing, with no findings released as of Tuesday night.
