PRINEVILLE, OR -- The city of Prineville and Crook County's Air Quality Committee will provide four giant dumpsters, Saturday, to help residents clean up their yards before winter. City Planning Director Phil Stenbeck says the "100 Yards of Yard Debris Challenge" is designed to get rid of stuff that would otherwise be burned. "There's a lot of folks that will possibly rake up leaves and these kinds of things, and then burn them in their yard and put smoke in the air," Stenbeck tells KBND News, "And so what the committee is aimed at doing is reducing the amount of particulate, and this is one of the ways we do that. Just to make people breathe cleaner air, nicer air. Prineville has good air, but we're still making an effort to eliminate particulate when we can."
