Update at 5:45 p.m. on Oct. 1 – Emergency response teams are wrapping up their operations in Teutopolis, Illinois State Police announced.

Since Friday night, a number of local, state and even federal agencies have worked together in responding to 4,000 gallons of leaked anhydrous ammonia. Those agencies included the Effingham County Sheriff’s Office, Teutopolis Fire Protection District, Illinois Departments of Transportation and Public Health, the Illinois Emergency Management Agency and Office of Homeland Security and the U.S. Environmental Protection Agency.

Teutopolis residents were allowed to return to their homes before 8 p.m. on Saturday, with law enforcement lifting evacuations along affected areas. Law enforcement also cleared the scene of all involved vehicles and Route 40 was reopened to traffic.

The Illinois Environmental Protection Agency will continue to address any contamination resulting from the incident while the Illinois State Police continues its investigation into the crash, including traffic crash reconstruction.

“IDPH is working with our local health department partner to monitor the situation and provide needed support,” IDPH Director Dr. Sameer Vohra said. “We remind residents to ventilate their homes upon return. If they detect unusual odors, they should leave immediately and call 911.”

Vohra added that the IDPH is working on guidance for testing private water wells by the crash scene to check for possible contamination. The IDPH will also remain in consultation with the local health department and the Illinois Department of Agriculture regarding animals and livestock in the area, and procedures for veterinary evaluation.

The Illinois State Police extended their gratitude to all agencies and first responders involved in assisting the situation.

“I am impressed with the quality and amount of assistance received from the local and state agencies,” Effingham County Sheriff Paul Kuhns said.

For additional information about the five fatalities, people may contact the Effingham County Coroner’s Office.

Update at 4:30 p.m. on Oct. 1 – The Effingham County Coroner has released the names of the three adults and two children who died as a result of a Friday’s ammonia leak.

Update at 3:50 p.m. on Oct. 1 — Tom Chapman, a Board Member of the National Transportation Safety Board, addressed the media on Sunday to give an update and offer new information about the deadly HAZMAT crash in Teutopolis.

Chapman said the NTSB’s investigation is one regarding safety, parallel to an Illinois State Police investigation into the crash. The NTSB is interested in issues related to cargo tank crash worthiness, hazardous materials routing and operartions of the truck.

“Our mission is to understand not just what happened, but why it happened and to reccomend changes to prevent it from happening again,” Chapman said.

The ISP will be the ones who determine why the crash occured, and so far, they’ve uncovered some details about the cause.

The ISP investigation determined that the tanker was operated by Prairie Land Transport Limited of Brownstown, a town west of Effingham that Route 40 runs through and which is located just north of Interstate 70. At 8:40 p.m. on Friday, the tanker was driving westbound on Route 40 near Teutopolis when another vehicle may have tried to pass the tanker, which caused the driver to swerve to the right and the truck ran off the road.

The truck subsequently rolled over and jackknifed, exposing the front of the tank. Chapman added that momentum carried the tank toward a small utility trailer that was parked illegally near the side of the road. The front of the tank hit the utility trailer’s hitch, which tore a six-inch-diameter hole into the tank.

There was 7,500 gallons of anhydrous ammonia in the tank, and approximately half of it leaked out through the hole. Chapman explained that anhydrous ammonia is commonly used for industrial and agricultural purposes, and it is both caustic and hazardous in its concentrated form.

Chapman added that while HAZMAT incidents involving anhydrous ammonia have occured in the past, they are usually of smaller scale. Larger quantities of anhydrous ammonia are usually offloaded into smaller “nurse tanks” used for agricultural purposes. The nurse tanks are where anhydroius ammonia incidents occur, not larger transport tankers.

Chapman said the NTSB investigate team will be on-scene for four to six days and a prelimianry report is expected to be published in about 30 days. Final reports will take between one and two years to complete.

Chapman also encouraged witnesses of the crash or anyone with additional imnformation about the crash, including video footage, to email the NTSB at wittness@ntsb.gov.

Update at 11:23 a.m. on Oct. 1 – Illinois State Police said U.S. Route 40 will be closed again from 12 p.m. to 2 p.m. as officials investigate Friday night’s crash.

According to a Facebook post from ISP Troop 9, U.S. Route 40 from St. Francis Township and Effingham County North 1950th Road will be closed. Traffic will be rerouted in Montrose south to Dieterich and back onto U.S. Route 33 from Effingham. In Effingham, truck traffic will reroute from Fayette Avenue and Willow Street to U.S. Route 33, to Dietrich, and back north to U.S. Route 40.

National Transportation Safety Board crews are in the area and are working with local authorities on the investigation. They plan to address the public later this afternoon.

Update at 9:15 a.m. on Oct. 1 – U.S. Route 40 has been reopened to traffic after spending over 24 hours shut down.

One retired firefighter said he’s never seen anything like what happened and helped others as they tried to find safety.

State Representative Adam Niemerg lives in Teutopolis and expressed frustration with the traffic in town. He said construction on Interstate 70 is sending trucks like the tanker through town.

Meanwhile, McMahon also explained what anhydrous ammonia is and what can happen to someone who breaths it in.

Update at 2 p.m. – Officials from the Illinois Environmental Protection Agency said the semi-truck was carrying approximately 7,500 gallons of anhydrous ammonia when it crashed. Early estimates indicate that 4,000 gallons were spilled, which prompted the evacuation of approximately 500 people.

The leak has been partially patched, officials said.

A contractor hired by the tanker’s operator is en route to the scene to review the situation and determine the best way to safely empty the tanker. A contractor from the U.S. EPA is also en route.

Evacuation orders for the affected area remain in effect. The area begins near the four-way stop in Teutopolis at Main Street and continues east on U.S. Route 40 to the area of 2100th Street.

People are strongly advised to stay at least one mile north or south of U.S. Route 40, staying behind emergency units and barricades.

“We realize that these road closures by the evacuations, what a hardship that is to several of our citizens,” said Effingham County Sheriff Paul Kuhns. “But what I can ask is please, please cooperate with this as we mitigate this HAZMAT [situation].”

Kuhns also clarified that, while State Police reported five people had died in the crash, the exact number of fatalities is actually unknown. State Police later revised their reports to the media, saying only that “multiple fatalities” were confirmed.

Several agencies are at the crash scene, including the Illinois State Police, several local police departments and almost all of Effingham County’s local fire departments.

Bruce Wagner, an acting-Lieutenant in the Illinois State Police, added that the crash on Route 40 happened during a detour of traffic off Interstate 70. Three semi-trucks were involved in that crash and one caught fire, but only one of the drivers was hurt. They are expected to be ok.

Officials could not provide a timeline for when evacuated residents could be allowed back into their homes. They said things would return to normal once the ammonia is offloaded and taken away from the scene.

The cause of the HAZMAT crash is still under investigation.
