LA CROSSE, Wis. (WKBT) -

The propane shortage is hitting the La Crosse Police Department. 

Sixteen squad cars were retrofitted to be able to run on propane back in 2012. 

In the past, officers were able to fill up their car for about a dollar per gallon of propane after rebates and tax credit. Now it's about $4 a gallon. 

Before the price spike, that was obviously a big money saver. 

"Last year alone, I estimated about $70,000 in fuel related cost savings, said La Crosse Police Assistant Chief Robert Abraham. “But there are some expenses as far as investing in the kits and transferring them, but overall we are saving money with the propane program and it's a little better for the environment.” 

It cost about $5,500 for the kits plus installation. Switching between gas and propane is as easy as pushing a button. 

The assistant chief hopes the prices will come back down within six weeks.
