Salt Lake County Mayor Ben McAdams unveil the county's new compressed natural gas (CNG) fueling station on Tuesday and said it will contribute to cleaner air in the Salt Lake Valley. The county's fleet maintains large diesel trucks that have contributed significantly to winter and summer air pollution.

"Switching to cleaner natural gas as a fuel shows that Salt Lake County is doing whatever we can to help lower the number of bad air days in the valley," McAdams said in a news release. "Replacing diesel fuel with CNG is a significant step towards less air pollution and more cost-savings on fuel."
