The Grand County Planning Commission has approved a zoning change that would allow hazardous-waste burning at Cisco if voters approve a Colorado company's proposed incinerator plant in a November referendum election.

The planning board's recommendation will next go before the Grand County Commission, which may schedule a public hearing on the issue.Planning commissioners backed a request by CoWest Incineration Corp. of Denver and a subsidiary company, Cisco Development Inc., to rezone approximately 190 acres at Cisco for commercial and heavy industrial use.

The planning board earlier approved a CoWest rezoning request that would allow development of four hazardous-waste incinerators at Cisco. However, planners now have put that on hold until voters decide in November whether they want hazardous-waste burning in Grand County.

The zoning change, if completed, would change the incinerator plant site from its present grazing zoning to heavy industrial use.
