759.06 SURVEILLANCE OF BLASTING.

   (a)   The contractor shall employ a qualified blasting seismologist (such as Geosonics, Vibra-Tech, etc.), subject to the approval in writing of the Safety Director or his/her designee, with at least five years practical experience in seismological measuring, to conduct seismological surveillance of all blasting operations in the Municipality. The seismologist shall keep daily records of all blasting activities for a period of not less than three years.

   (b)   The seismologist will report any violation of this chapter immediately to the Safety Director or his/her designee. Upon the violation of any provision of this chapter, the Safety Director or his/her designee may cause the immediate revocation of the blasting permit.

   (c)   The violation of any provision of this chapter shall constitute a forfeiture of any prepaid permit fees or refundable permit fees due the permit holder. Whoever violates the provisions of this chapter regulating blasting, upon conviction thereof, shall be deemed guilty of a misdemeanor and fined in an amount not exceeding one thousand dollars ($1,000) for each offense. In the event any permittee or licensee violates the standards as herein established on more than three separate occasions, as reported by the seismologist, the Safety Director or his/her designee, shall have authority to take any appropriate action, including, but not limited to the following: revoke any and all outstanding blasting permits granted to the benefit of the permittee, licensee or any other individual and/or entity acting through and/or on behalf of the permittee and/or licensee; refuse to issue any further permits to such permittee or licensee at any subsequent time and to pursue any civil remedy, be it injunctive relief, damages or otherwise, which the Safety Director deems appropriate.

   (d)   The seismologist shall issue written reports on each and every blasting event to the Safety Director or his/her designee and the permit holder, licensee and/or contractor, which reports shall include comments upon compliance with regulations and standards herein established. These reports shall be filed with the Safety Director or his/her designee within twenty-four hours after each blasting event, or at the latest, prior to the next blasting event if same occurs prior to the expiration of twenty-four hours.

   These written reports shall contain the following information:

      (1)   The name of the firm and/or individual conducting the blast;

      (2)   The location, date and time of the blast;

      (3)   The name and signature of the qualified blaster conducting the blast;

      (4)   A report of weather conditions, including temperature, wind direction and velocity, etc.;

      (5)   A description of the type of material blasted;

      (6)   The number, diameter and depth of blast holes;

      (7)   The type of, identity of manufacturer of, and amount of, explosives used;

      (8)   The total weight of explosives used;

      (9)   The weight of the explosives per hole;

      (10)   The maximum weight of explosives detonated within any eight millisecond period;

      (11)   The type of initiation or detonation system used;

      (12)   The delay pattern, including the actual firing time of each hole;

      (13)   A sketch, in reasonable detail, of the blast pattern showing all holes, delay patterns, previously blasted material and an indication of north;

      (14)   At the completion on the blasting operation, a final map, in reasonable detail, of the permit area, showing the location of each blast, and identifying each location with the date, time and other pertinent information concerning each blast;

      (15)   Seisographic and air blast records, including the following:

         A.   The type of instrument, sensitivity, and calibration signal of the device. Also, a certification that the equipment has been calibrated with, within the past year, along with a written indication showing any and all calibrations done within the past year, and the results of those calibrations;

         B.   The exact sensing location of the measuring instrument, along with an indication of the date, time and distance from the blast;

         C.   A report describing the electronic analysis of frequency vs. particle velocity. This is to be in a format which would demonstrate compliance with the graph which is part of this chapter (Modified Figure B-1, Bureau of Mines, RI 8507);

         D.   An air blast levels report; and

         E.   The name of the person and/or firm analyzing the seismographic record.
