Crews Responding to Chemical Spill; Multiple Locations in Pocatello, Bannock County

UPDATE: Crews have completed neutralizing the sulfuric acid in Pocatello. 

They will now begin sweeping the affected roads. Streets will be reopened once they are swept. Officials estimate clean-up in Pocatello will be completed around 3 a.m. 

PREVIOUS RELEASE: Currently, trucks with the neutralizing solution are making their way along the route. 

PREVIOUS RELEASE: Emergency crews are responding to a sulfuric acid spill in multiple locations in Pocatello and Bannock County. 

The spill was reported to officers with the Pocatello Police Department just before 7 p.m.

The route of travel for the individual transporting the acid includes: 

- U.S. Highway 30 from Soda Springs to Old Highway 91

- Old Highway 91 to Fort Hall Mine Road

- Fort Hall Mine Road to Portneuf Road

- Portneuf Road to Bannock Highway

- Bannock Highway to Main Street

- Main Street to Gould Street

- Gould Street to McKinley Avenue

- McKinley Avenue to the 700 block of McKinley Avenue


Over the night, crews with the Pocatello Fire Department Hazardous Material Team in conjunction with City of Pocatello Street Operations Department will be mixing a neutralizing solution and putting it down on the spill using Street Operations deicing trucks. After the acid has been neutralized, crews will sweep the road surfaces to remove it from the road. 

At this time, officials estimate 60-65 gallons of 93-98 percent sulfuric acid were spilled. 

If you believe you may have driven through the spill, do not wash the acid off by hand. The Idaho Department of Environmental Quality says the acid that may have gotten on a vehicle’s tires can be cleaned by using a commercial-grade sprayer with soap and water. The water and soap will help to neutralize the acid and not contaminate the water supply. 

Due to the spill’s size, emergency crews are unable to station personnel at every intersection impacted by the spill. Cones and other barriers have been put up to warn the public about the spill. Please avoid the impacted areas and officials thank the public for their patience and cooperation. 

Responding agencies include the Pocatello Police Department, Pocatello Fire Department, Bannock County Sheriff’s Office, Idaho State Police, and Regional Response Team 6.
