A. Blasting activity that is to occur within one thousand feet (1,000') of any school, university, daycare center, church, library, medical facility or any public building shall be conducted during off hours where possible and shall require seismic monitoring of each blast to ensure the integrity of the building, as well as the safety of the occupants. Since there is a wide variety in the type, density, specific gravity, velocity and general characteristics within the geographical area of southern Utah, there are varied methods that can be employed to attain the desired results. These methods, if used however, shall adhere to the appropriate limit criteria. (Ord. 2012.04, 1-18-2012)
B. Any blasting that is intended within five hundred feet (500') of any structure, tunnel, underground utility, overhead transmission lines, pump station or radio tower requires that the blast be monitored with a seismograph capable of measuring peak particle velocities in three (3) spatial components: horizontal, vertical and transverse, and shall be capable of printing this data into a permanent record as digital, as well as waveform, and air blast overpressure in terms of millibar, psi or decibel recording of each event. All permanent structures within five hundred feet (500') of the blast area shall be required to have a preblast inspection performed at the expense of the contractor and/or blaster, by an independent company whose primary business is to conduct and perform these types of services. The said company will deliver to the Hurricane Valley fire district a copy of the preblast inspection prior to the issuance of a blasting permit. A certificate of insurance issued by an underwriter legally doing business in the state showing the contractor and/or blaster to be properly insured for the express purpose of blasting and showing the issuing agency as additional insured, shall be submitted with the application for a blasting permit. (Ord. 2012.04, 1-18-2012; amd. 2014 Code)
C. A blasting permit shall be site specific and expire thirty (30) days from issuance.
D. Special signs to warn the public of blasting operations shall be erected in a manner as to be clearly evident to the public during all critical periods of the blasting operations.
E. Notice shall be given to all utilities with facilities adjacent to the operation with sufficient time to allow said utilities to advise the contractor of any special circumstances or precautions to be taken.
F. Blasting shall be accomplished in such a manner that nearby buildings, structures, railways, highways, etc., will be safe from rocks and other projectiles. Adequate blasting mats or other means of protection shall be employed when blasting in congested areas, or close proximity to improvements. (Ord. 2012.04, 1-18-2012)
