(a) Blasting operations shall be so conducted that ground vibrations measured at the nearest structure or building, neither quarry nor contractor-owned or leased, except high-tension lines, supporting towers and appurtenances, do not exceed a peak particle velocity of two inches per second or its equivalent on any of the three mutually perpendicular planes of motion, i.e., vertical, longitudinal or transverse. No blasting operation will be permitted within 150 feet of any dwelling, building, school, church or theater or any structure which the Chief of Police or the seismologist may deem hazardous, except when Council, upon advice of the seismologist, determines that the purpose of the blasting is in the interest of community development and such blasting will not pose a hazard to surrounding structures, and, further, when the seismologist advises that a modified charge shall not create damage to adjacent structures.
(b) Nothing herein shall preclude or prevent any claimants from making a claim for damage as a result of blasting done hereunder through a liability carrier of the applicant in the usual fashion.
(c) Blasting operations conducted within the allowable limits of ground motion and particle velocity contained in this section shall be considered structurally non-damaging to structures.
(d) A record of the seismic wave pattern shall be kept for a minimum of three years after project completion by the seismologist and the same shall be filed in the permanent records of the Village.
(e) No blasting operations shall be permitted unless the seismologist is present.
(f) When the characteristics or environment of any specific blasting event have been determined to be extraordinarily hazardous by the seismologist and the Chief of Police, additional safety precautions may be lawfully required. The permittee shall be advised of the nature of such extraordinary hazard and instructed as to what specific additional safety requirements are required.
