“We can’t apologize enough. We did not communicate well, we were not proactive in reaching out. And, it affected the community,” said Maverik President Chuck Maggelet at a Tuesday meeting at the Lander Community Center.
Leaders from the community were invited to the presentation regarding the discovery of a fuel leak from the Maverik fueling station at 135 E. Main Street.
On April 2nd, Lander firefighters were dispatched to a section of the Popo Agie River between 1st Street and Caring Way for the fuel leak report. A pedestrian reported being able to see a gasoline-like substance in the water and that he could smell fumes from the river.
On April 12th, the Wyoming Department of Environmental Quality cited Maverik for failure to make necessary repairs to prevent overfilling of the unleaded gasoline tanks.
Maggelet and Vice President of Fuels, John Hillam explained to Lander leaders that the leak occurred after three simultaneous system failures. A check valve, pump relay, and alarm reporting system all failed to work. “We’ve never seen had anything like this in any of our stores,” Maggelet explained.
A timeline was provided as part of the presentation of the series events leading up to the leak.
