David Buckley of Grand County Road and Bridge told commissioners Sept. 9 that the county needs to finalize a contract with Colorado Lining International to install a geomembrane liner at the Granby landfill under a Colorado Department of Public Health and Environment (CDPHE) grant.

Buckley said the contractor has signed the contract and the installation must happen this fall to meet the grant timeline; he asked that the chair sign the contract to make it fully executed so installers can set dates. “...we're running out of time. We have basically until October to get this done,” Buckley said.

Buckley said the contract price reflected recent negotiations and the amount presented in the meeting materials was $168,915.20, an increase of $724 from an earlier draft. He said the state (CDPHE) has approved the revised amount and that the work will be reimbursed through the grant.

Buckley described installation details: extending the membrane 20 feet on each side (and additional footage to the south), using an overlay liner to function as drainage (reducing hauling of sand or wood chips), and placing clay material over the liner. He said an earlier installation in 2022 left some exposed membrane and that rolls from 2022 were considered for this extension.

Buckley also reminded the board that CDPHEpost-closure plan previously included a large engineering study in the approximately $25,000,000 range; he said ongoing monthly surveys and biannual well sampling are in place for monitoring.

Why it matters: The work is part of a grant-funded closure/maintenance process overseen by CDPHE; timing affects contractor availability and compliance with the grant fiscal-year schedule.

Next steps: Buckley requested the chairsign the contract so a specific installation date can be scheduled; the transcript excerpt does not show the chairsignature or a recorded board vote in the provided segments.
