California Regulators Under Scrutiny After Garden Grove Chemical Plant Crisis

A near-catastrophic incident at a GKN Aerospace chemical plant in Garden Grove has exposed what critics describe as a deeply underfunded and ineffective regulatory system, leaving residents and local leaders demanding change. The crisis began when a tank at the facility, located at 12122 Western Ave., overheated and bulged, forcing the evacuation of an estimated 50,000 residents.

Firefighters intervened to prevent an explosion, and a state of emergency was declared.

For over 20 years, neighbors lived quietly alongside the plant, unaware of repeated fines and regulatory questions about air emissions and equipment maintenance. A Voice of OC investigation reveals a pattern of lax enforcement: between 2013 and 2025, the South Coast Air Quality Management District issued eight notices to GKN, including two in 2025 for missing permit records and emission data.

In 2021, the district fined GKN nearly $910,000 for failing to track toxic emissions for at least five years, missing permits, and using banned coatings.

State and federal OSHA records show additional fines: $2,500 in 2019 for failing to implement an injury prevention program, and $420 in 2022 for not providing respirators during the pandemic. Despite these violations, the plant continued operating uninterrupted.

GKN’s parent company, Melrose Industries, reported $869 million in operating profits last year, while GKN posted over $4.8 billion in sales.

Former Cal/OSHA compliance officer Garrett Brown, who spent 20 years at the agency, said understaffing has crippled enforcement. “No one has time to do planned inspections because they’re dealing full time with worker complaints,” Brown said.

He noted that on-site inspections now occur in less than half of cases, with many complaints resolved by asking employers to self-report. A July 2020 Cal/OSHA-commissioned report confirmed staff were overburdened, and a July 2025 state auditor’s report found that nearly one in three Cal/OSHA jobs were unfilled, with failures to follow up on violations.

The South Coast Air Quality Management District, which oversees 17 million people across four counties, employs only about 100 inspectors—roughly one per 110 square miles. The Garden Grove plant was last inspected on March 7, 2025, when inspectors found equipment operating without permits.

Local leaders are now pushing for change. Congressman Lou Correa said, “We cannot have this situation where these kinds of chemicals are done in a very densely populated area without proper safeguards.” Congressman Derek Tran plans to introduce legislation requiring chemical plants to notify nearby residents.

State Assemblyman Avelino Valencia called for stricter accountability, and Garden Grove Councilman George Brietigam said the city was never informed of state citations against the facility.
