Petrified Forest National Park

Set partly within the Painted Desert of northeastern Arizona, Petrified Forest National Park offers glimpses of the world's largest concentration of petrified wood, fossils, and a fragile grassland ecosystem. Working with Tucson Clean Cities Coalition (TCC), the park replaced all gasoline-fueled vehicles within its Visitor Services fleet and installed two publicly available electric vehicle charging stations in the park. It also worked with TCC to launch an extensive education and outreach effort designed to educate park visitors, tour bus drivers, and park staff about how to eliminate unnecessary engine idling, reduce fuel consumption, and improve local air quality. The old vehicles were replaced with one plug‐in electric vehicle and one hybrid electric vehicle. The electric vehicle supply equipment included a DC Fast Charger with Level 2 capabilities located at the park's north visitor center.
