The Pennsylvania Department of Environmental Protection (DEP) has awarded more than $1.6 million to schools and businesses in the state for projects that will use alternative fuels and infrastructure. Ten grants were awarded, mostly for alternative fuel vehicle purchases and retrofits. Those include 41 propane-fueled buses for a school district in Montgomery County and 20 United Parcel Service trucks that will run on compressed natural gas. In all, 111 alternative fuel vehicles will be put into service through the grants and utilize seven new alternative fuel stations. The grant program remains open throughout 2016. Applications will be accepted until Dec. 30 for "innovative, advanced fuel and vehicle technology projects," the agency said.
