WICHITA, Kan. -

A FactFinder 12 Investigation is getting results.  

We told you last week about a federal rule that is cutting off the supply of fire trucks to rural fire departments. Now members of congress are stepping in.

Senator Jerry Moran took the issue to the Senate floor Tuesday.

"95% of Kansas is protected by rural fire departments," Moran told FactFinder 12.

Rural fire departments buy many of their trucks through a military surplus option. Trucks that normally cost up to $100,000 or more are sold for as little as $5,000. 

Others are provided on loan through the forest service. The trucks are then repurposed and used to fight grass fires.

The Kansas Forest Service says the trucks are essential to small fire departments. But now the military has ended the program due to an old agreement with the EPA because the trucks don't meet emission standards.

"This idea from the Department of Defense just lacks common sense," Moran says.

At least three rural fire chiefs agree and told FactFinder 12 what would happen if they lose access to the trucks.

"It will put us out of business," says Rosalia Fire Chief Dean Bender.

"Without it we're not going to have a department," adds Leon Fire Chief John Mellies.

Moran and other members of the Kansas delegation including Senator Pat Roberts, Rep. Lynn Jenkins, Rep. Mike Pompeo, and Rep. Tim Huelskamp are sending a letter to the Department of Defense Wednesday.  Moran says he hopes it can be solved quickly, but if legislation is needed that's what he'll do.

"We are going to do everything we can to get the Department of Defense's attention to change course. Those trucks must be available to Kansas fire departments," says Moran.
