Regulations that might prevent a proposed hazardous-waste incinerator from being built in Lynndyl, Millard County, were approved for public comment Wednesday afternoon by the Utah Solid and Hazardous Waste Committee.

Preliminary rules on siting hazardous-waste incinerators, if adopted as law after public hearings, would bar the burners from within five miles of surface waters or permanent habitations.The Millard County site, where Rollins Environmental Services would build its plant, is within Lynndyl and apparently is closer than five miles from the Sevier River. Besides all rules that the state and federal government impose, cities and counties would be allowed to add their own.

Wednesday's action came just a week after the Legislature voted for a moratorium on issuing permits for incinerators. The moratorium is effective until the committee adopts siting regulations.

According to the Legislature, the rules must be in place by next May 1, but most likely they will be effective by the first of the year.

The proposed regulations also would ban hazardous-waste facilities from parks, wilderness and recreation areas, flood plains, places with high-quality groundwater, and any region where groundwater can reach from the facility to within 1,000 feet of a well in a year.

Other criteria would force the company to prove emergency services, such as medical assistance and firefighting, are available. The company must coordinate with local emergency-response officers.

The incinerator or storage facility must be monitored and meet strict federal requirements against leakage. County and city governments can add more stringent rules but cannot reduce the state requirements.

Bureau director Brent Bradford said the moratorium measure is specific that the criteria will apply to all such operations, whether they have already filed applications or will in the future.

The requirement of distance from a well is designed to be an extra protection, a buffer zone where contamination would show up. The plant is supposed to monitor groundwater quality, and it is expected to detect any leakage when it happens.
