Adams County approves $2.72M mag-chloride dust-abatement contract to meet air-quality rules
Summary
The board approved a three-year, $2.724 million agreement with GMCO Corporation for mag-chloride dust-abatement services on gravel roads to comply with PM10 nonattainment requirements from state and federal air-quality agencies.
The Adams County Board of Commissioners voted Jan. 7 to approve a three-year contract with GMCO Corporation for mag-chloride dust-abatement services totaling $2,724,194.43.
Janet Lindquist, deputy director of public works, said the contract breaks down to approximately $908,064.81 per year and noted the county received two bids, with GMCO as the lowest responsible bidder. She told the board the work targets gravel roads with annual daily traffic above the regulatory threshold and is intended to keep the county in compliance with particulate-matter (PM10) nonattainment standards administered by the Colorado Department of Public Health and Environment and the U.S. Environmental Protection Agency.
Lindquist said, "Public Works is purchasing dust abatement services to comply with particulate manner, PM 10, nonattainment area." She added the program reduces surface gravel degradation, vehicle wear and tear and impacts to nearby dwellings and agricultural uses.
Commissioners moved and seconded the resolution; the motion passed unanimously.
Implementation will be managed by Adams County Public Works under existing pavement and gravel-road maintenance programs. The board also discussed the county's prior contract-review practices while considering several consent-calendar items during the same meeting.
