The City-County Health Department will hold two public hearings next week on proposed changes in the vehicle-emissions inspection and maintenance regulations.

The hearings will be Monday, April 15, at 2 p.m. at the City-County Health Department, 589 S. State, Room 74; and Wednesday, April 17, at 7 p.m. in the Provo City Council chambers, 351 West Center.The proposed changes are necessary to bring the county's program in line with new state and federal laws, according to Ralph Clegg, assistant director of the health department.

The proposed changes would:

- Require emissions testing stations to use computerized testing analyzers, which cost $10,000 to $12,000.

- Establish a more stringent emission standard for hydrocarbon in Utah County. The change will bring the county's standard for that pollutant in line with the standard in Salt Lake and Davis counties.

- Tighten control on emissions-repair waivers and increase minimum repair amounts.

- Create standards for regulating the switching of engines in a tested vehicle.

- Allow by provision for Utah County testing mechanics to perform Davis, Salt Lake and Weber county tests.

- Increase the emissions-testing fee from $9 to $12.

County residents are invited to comment on the proposed changes during the two hearings.

The health department also will accept written comments. Written statements should be sent to Joseph K. Miner, director, City-County Health Department of Utah County, 589 S. State St., Provo, UT, 84606.

Copies of the proposed changes are available at the health department for review. For more information, contact Ralph Clegg at 370-8700 or Terry Beebe, emissions program supervisor, at 370-8780.
