The Clay County Commission voted Thursday to revoke an earlier conditional-use permit and adopt a new conditional-use permit for a quarry south of Highway 210, after county planning staff said conditions of the 2024 renewal were not met.

Kip Jones, the county planning director, told commissioners the matter combines two related cases involving a property that includes an underground cave area now used by Cold Storage Solutions and an adjacent surface quarry. "We have basically 2 cases kinda wrapped up into 1 with the conditional use permit," Jones said during his presentation.

Under the new draft CUP, staff added and adjusted conditions intended to reduce impacts on neighbors and infrastructure: increase the required blast distance from the property line from 200 feet to 250 feet, increase the blasting distance for a base rock layer to 400 feet, prohibit truck traffic from crossing the Old 210 Bridge even after its replacement, require the applicant to move the quarry entrance farther from Cold Storage Solutions and to maintain the section of Old 210 Highway used by quarry trucks for any damage caused, and restrict an interior haul road to light vehicles to reduce dust.

Jones said planning staff recommended approval with 22 conditions; the Planning and Zoning Commission voted 7-0 to approve the permit with two amended deadlines that shorten the time for required changes. The Planning and Zoning Commission reduced the timeframe for separating sewer systems from six months to 90 days and shortened the time for moving the entrance from 120 days to 90 days.

The applicant, Mr. Bueller, told the commission he agreed to the revised conditions and said he had already completed moving the entrance on the south side of the property. Jones said no quarry activity will be allowed until required conditions are completed; "No activity is allowed but he has 90 days from the approval date to complete those conditions otherwise we would bring back another revocation to the planning and zoning commission and county commission," Jones said.

The county's new CUP language also requires the applicant to avoid truck traffic across the Old 210 Bridge, a structure Jones said is currently closed and being replaced; commissioners discussed how compliance would be policed and said county road staff can monitor and take action if trucks cross the bridge.

The commission voted to revoke the previous CUP and adopt the new CUP with the outlined conditions; the roll call showed the motion passed 6-0.

Ending: Staff will monitor compliance with the 90-day conditions; the commission said it would return the matter to planning and zoning for enforcement action if the applicant does not complete required work within the deadline.
