SALT LAKE CITY -- An incident at the Tesoro Refinery in Salt Lake City left a coating of oil all over a local park Friday.
Warm Springs Park was temporarily closed as emergency crews worked to remove oil from the lawn and facilities. According to the refinery, the oil release occurred after an equipment malfunction late Thursday night, but they did not realize it had spread past their facility until the morning.
“Anytime we hear of an infrastructure failure, as we did this morning, we are greatly concerned,” Salt Lake City spokesman Art Raymond said.
The city was notified of what happened around 7:00 a.m. Friday. Tesoro described the leak as a “faint oil mist” that was carried into the park and surrounding area.
While the incident is still under investigation, Tesoro officials said they believe a pressure release valve in one of its units failed to work properly, causing the oil to shoot out.
According to residents, alarms at the plant started ringing Thursday evening.
“I had a friend that heard these alarms around 8:30-9:00 o’clock last night. Being as quiet as it is at that time, he could hear them saying, ‘Emergency, evacuate,’” said resident Steven Kaufman.
Tesoro placed barriers in certain areas around the park to ensure that all oil was removed from water before it entered any storm drains. While the company denied FOX 13 News' request for an interview, they did send the following list of questions and answers.
