About 72 ratepayers will no longer benefit from no-charge calcium under the county’s dust abatement program. “We will be knocking 30 kilometres of dust abatement off the program,” said Mark Harbicht, the county’s director of municipal services. The locations are near former aggregate pit haul routes. The county will continue to apply calcium on county aggregate haul routes for 100 meters in front of residences. He told council on Thursday the new policy will save the county about $140,000.
