Sign-up deadlines for dust treatments on county roads are approaching. Tammy Van Gorp, with the Marion County Engineer’s Office, says that there are three approved vendors that rural residents may contact if they are interested – Smith Fertilizer and Grain of Knoxville, Binns and Stevens of Oskaloosa, and Heffron Services of Van Meter. Marion County residents must contact one of those vendors by April 13th in order to be assured of services. The first applications will begin May 15th. If you have any questions, you can call one of the vendors, or you can reach the Marion County Engineer’s Office at 828-2225.
