U C� area, nor is the blasting area within 500 feet of an active or abandoned underground mine, no monitoring is proposed. As blasting will not be conducted within one -half mile of any dwellings or structures, no pre - blast surveys are anticipated to be conducted. To ensure compliance with restrictions on peak particle velocity, any blasting at the mine will comply with the limitations on maximum weight of explosives contained in Rule 4.08.4(10)(c)ii). Blasting Schedule GCC Energy will publish a blasting schedule between 10 and 20 days prior to initiating the surface blasting program in the Durango Herald the newspaper of general circulation in the area of the mine. The blasting schedule will: • identify the location of blasting • time periods during which blasting will occur • measures to control access to the blasting area • the pre -blast warning and all -clear audible signals • the unavoidable hazardous conditions which would require blasting outside the approved blasting schedule If changes to the blasting schedule are necessary, the blasting schedule notice will be republished. Unavoidable Hazardous Conditions Blasting will occur during times indicated in the blasting schedule unless dangerous atmospheric or site conditions, as determined by the blaster - in- charge, require detonation to avoid accidental detonation. If so directed by an authorized law enforcement or regulatory agent, blasting may occur outside the times specified in the blasting schedule.
