Catoctin Mountain Park

Working with the State of Maryland Clean Cities coalition, in 2014 Catoctin Mountain Park replaced two conventional vehicles with plug-in hybrid electric vehicles and installed three electric vehicle charging stations for park and public use. The park also replaced four gasoline lawnmowers with propane mowers and shares their use with a nearby military base. Additionally, the project included an idle-reduction education and outreach initiative.
