PHOENIX — The Tucson facility where the Arizona Department of Transportation repairs and maintains its vehicles has significantly reduced the amount of trash it generates by recycling scrap metal, batteries, automotive fluids, paper and more. Converting to LED lighting has reduced energy use.

Along with ADOT’s repair facility in Springerville, the Tucson operation has been recognized through the agency’s Green Shop program, which seeks to minimize environmental impact, cut waste and increase recycling at 22 ADOT Equipment Services locations.

“We’re reducing the cost to the state because we’re keeping waste down,” said Nathan Carroll, the fuel, scales, environmental and training manager for ADOT Equipment Services. “The end result is increasing productivity. For the taxpayer, that’s a good thing.”

The Green Shop program began in 2006 with a best-practices manual offering guidelines on subjects including keeping shops clean and organized for efficient operations and properly containing spills. It has become an important part of daily operations at all ADOT service shops.

More than 40 government agencies contract with ADOT Equipment Services, including the Arizona Game and Fish Department, Arizona Department of Public Safety, police departments and school districts. The shops perform preventive maintenance and major repairs on light trucks, snowplows, watercraft, snowmobiles, school buses and more.

Every two years, one full-service shop and one satellite location are honored following three inspections, one of which is unannounced, to see how operations are following the Green Shop guidelines.

An event to honor the Tucson operation was held April 8. An April 18 ceremony is scheduled at the Springerville facility.
