Background. Road improvements were needed on 11.5 miles of county owned roadways leading to a new mine site in order for the mining operation to obtain the required operating permit.
Background. Winter freezing causes the surface at mine tailing disposal sites to freeze dry, which makes it a source of fugitive dust.
Background. An intermodal yard was plagued by chronic wind-blown dust, the result of the daily cycling of yard tractors, forklifts, and container-handling equipment.
