On March 30, 2019, a Union Pacific freight train derailed in a rural area roughly 1 mile west of mile marker 124 on US Highway 6 in Juab County, Utah. A total of 24 cars derailed including: 4 cars of monoammonium phosphate fertilizer, 1 car of phosphoric acid, 2 cars of diesel, 1 car of soda ash, 9 cars of propane and 7 other cars of non-hazardous materials. The phosphoric acid car appears intact while at least one of the diesel cars and several of the propane cars have breached and are leaking.

Several local Fire Departments, EMS, Law Enforcement, Utah County Emergency Management,  the American Red Cross, the State of Utah's Fire Marshall's Office, National Guard Civil Support Team, Union Pacific, various Union Pacific response contractors, Federal Railroad Administration and USEPA all responded to the incident. The phosphoric acid car was pulled away from the other cars and the leaking diesel fuel was contained. The primary concern of the response team are the propane cars which show signs of instability and present a danger to the responders. A specialized team has been mobilized to intentionally breach and thermally treat each of the propane  and diesel cars using explosive charges and remotely ignite the liquid that is released. This activity is tentatively planned for March 31, 2019.

No further actions are required by EPA at the site.  EPA is demobilizing from the site.

Any further remediation actions/oversight, if necessary, will be handled by the state.
