Teenagers will be cleaning up litter on state roads around Richland this summer.
Motorists are asked to use extra caution when they spot the orange "Ecology youth working" signs. The state Department of Ecology operates the Ecology Youth Corps program to keep state roads litter-free.
Work starts this week and will continue through July 20.
In 2011, Ecology Youth Corps litter crews cleaned nearly 5,225 miles of roadways, picked up 505 tons of litter and recycled 90 tons of materials.
Littering can draw fines up to $1,025. Fines for illegal dumping are $1,000 to $5,000, plus jail time.
