Douglas County residents wanting to sign up for the county’s road dust reduction program can pick up applications through March 7 at the Douglas County Public Works Department, 1242 Mass.

The program consists of applying liquid calcium chloride or magnesium chloride to rock roads in front of houses in an effort to reduce dust created by passing vehicles.

The cost of the program is paid by the participants. This year’s cost is $1.45 per linear foot of roadway treated, plus an administrative fee of $45 per location. The dust reduction treatment is expected to last a year.
