 Miami County Commissioners approved the 2009 Dust Control Program costing $263,900, which covers more miles this year than in previous programs.Road and Bridge Director J.R. McMahon said this year’s program plans for 42.5 miles of magnesium chloride application and 12 miles of oil surface dust control. Those numbers include about five more miles of magnesium chloride and three more miles of oil application, respectively, over and above the miles of road already in the program. According to county documents, the dust abatement program for gravel roads has been offered to county residents on a paid basis for 19 years. Subscribers to the service choose either oil or magnesium chloride application. Oil dust abatement involves application of asphalt oil followed by a thin layer of limestone chip. The limestone minimizes disruption of vehicle traffic and eliminates the problem of oil getting on the vehicles. The treated road tends to be somewhat dusty immediately after application, but excess rock chips tend to dissipate quickly as traffic resumes. County officials caution that, while magnesium chloride road abatement is less expensive than oil application, the chemical product isn’t as effective, and it tends to be adversely affected by weather and traffic, particularly in the summer months. When magnesium chloride is used, county workers water down the road surface before blading it and applying the chemical. This is done to help prolong the dust control effects. Miami County doesn’t guarantee the life expectancy of either of the abatement measures it provides, because there are a number of variables that can lessen effectiveness and duration of the treatments, including traffic, gravel thickness, severe weather and drainage. In other business, the county commission approved the following items:

Would have been nice to know what roads were going to be added to this year in this article. I am glad that the county is finally realizing that the old requirements for road dust control were not realistic. Unfortunately people no longer drive slow on gravel roads and the quality of the rock we are getting these days is terrible. It is 70% dust and when it rains the stuff disappears. The amount of dust that this poor road rock quality produces is a hazard not only to people with breathing difficulties but to peoples safety. Roads like New Lancaster north of 271s to 255th over to Quivira should be a treated road. The dust in this area often just hangs and the hills become dangerous do to the dust. Just doesn't seem right when some roads out in the middle of nowhere get asphalt like Lackman or Pflumm from 223rd to 247th street. You can't tell me 400 cars pass on that road a day. Let's start to maintain safer roads in Miami County.
