HO1_HO2_and_HO3_50ft_Veg_Clearing_Buffer.kmz

This is a Keyhole Markup Language (KML) file—a geospatial data format—related to the Wattis Mine Coal Fire Abatement project (BD27-113) issued by the State of Utah Division of Oil, Gas, and Mining. The project involves the sealing of five mine openings, eleven subsidence openings, fifteen exhaust vents and air intakes, and twenty-seven open cracks at an abandoned coal mine located in Carbon County, Utah. Work will be performed using excavation and grading operations, shallow boring drilling, and specialized equipment including a walker "spider" excavator with appropriate attachments to suffocate an active underground coal fire. A mandatory in-person site visit is required on Tuesday, October 20th at 10:00 a.m. at the northwest parking lot located at the intersection of UT-10 S Carbon Avenue and Ridge Road in Carbon County, Utah (GPS Coordinates: 39.536251, -110.816029). The meeting is expected to last approximately four hours and will involve driving and hiking over rugged terrain; high-clearance four-wheel-drive vehicles are recommended. Attendance by an authorized representative is mandatory to submit a responsive bid, and bidders are prohibited from entering the mines due to hazardous conditions.

The KML file contains geospatial mapping data defining a 50-foot vegetation clearing buffer zone around three designated areas (HO1, HO2, and HO3) at the project site. This mapping file supports the project planning and environmental considerations for the coal fire abatement work. The specialized nature of abandoned mine closure work and the unique hazardous conditions present at the site necessitate the mandatory pre-bid conference and site visit attendance requirement per Utah Procurement Rule R33-101-13.
