President Donald Trump on Monday granted California Governor Gavin Newsom's request for federal emergency funding to support the state's response to a hazardous chemical leak in northern Orange County that threatened to explode. The approval activates FEMA assistance for more than 785 state and local first responders deployed to the GKN Aerospace Transparency Systems facility in Garden Grove.
The incident, which began Thursday when a damaged tank overheated, forced the evacuation of approximately 50,000 residents. Officials said 34,000 have since been allowed to return. The tank held between 6,000 and 7,000 gallons of methyl methacrylate, a flammable liquid that sprayed from a crack in the fixture.
Newsom's office confirmed the federal aid will cover specialized equipment and other life-saving response activities. In a statement, the governor emphasized California is mobilizing all available resources to protect affected communities and support local response efforts. He added that state and local officials are coordinating evacuations, sheltering, environmental monitoring, and public information.
Orange County Supervisor Janet Nguyen, who signed the emergency declaration request, thanked Trump directly in a video posted to X, saying, "We thank you, President Trump, we appreciate you." The approval marks a rare bipartisan moment as the president and the Democratic governor set aside political differences to address the crisis.
Orange County Fire Authority Division Chief Craig Covey warned last week that the tank risked causing an explosion. An overnight assessment Monday found temperatures inside had dropped enough to reduce the immediate threat, but Covey cautioned that a smaller blast or fire was still possible. "It's not over yet," he told the Associated Press. "We still have work to do. We still have to mitigate a fire and very small explosion concern, and also a spill potential."
Methyl methacrylate exposure can cause respiratory and neurological issues, as well as irritation to the skin, eyes, and throat, according to the Environmental Protection Agency. Nguyen said the South Coast Air Quality Management District will monitor air conditions for months, while the EPA will analyze samples from sewer and storm drains. GKN Aerospace, the British manufacturer of cockpit parts for military and commercial planes, apologized for the "disruption."
The chemical leak was one of several disasters to hit Southern California in recent days. Last Monday, the Sandy Fire scorched over 2,100 acres in Simi Valley, northwest of Los Angeles. The California Department of Forestry and Fire Protection reported 90% containment as of Tuesday. On Friday, an underground pipe in East Los Angeles was struck by a telecommunications crew, releasing roughly 2,400 gallons of crude oil into storm drains and the Los Angeles River. County officials said the leak has been controlled.
The Trump administration's approval of disaster aid comes amid broader political tensions, including debates over Iran policy and domestic governance. Critics have questioned the president's focus amid multiple crises, but the swift response to California's emergency has drawn praise from local officials.
