Registration has opened for Adopt a Highway volunteer groups and others wanting a one-day permit to clean litter along a designated 1- or 2-mile segment of highway in Arizona.

The work will take place from dawn to dusk on Saturday, Sept. 17, which is National CleanUp Day, according to the Arizona Department of Transportation.

In 2021, 40 groups filled 150 trash bags in one day, ADOT reported in a release.

That's 2,053 pounds or 1.2 tons of litter removed from state roadways.

ADOT grants one-day permits on a first-come, first-served basis and will try to find an 'adoptable section' near the applicant's desired location, officials stated.

One-day permit holders who decide to keep the permit after National CleanUp Day for two years will have the first cleanup waived, according to ADOT. One cleanup is required after a new permit is confirmed to have the group recognition sign ordered and installed at the adopted segment.

All groups must report litter bags collected and the number of volunteers who participated within three days after the event.

ADOT tracks litter data to better understand where resources are needed to deal with trash along highways, ADOT officials said. Groups that report the information will receive a certificate of appreciation.
