§ 55-12. Information and requirements during and subsequent to geophysical seismic blasting.  


Latest version.
  • (a)

    For geophysical seismic blasting and under such other circumstances as may be specified by the county manager or designee, the following requirements shall be applicable during blasting operations:

    (1)

    The user shall provide a location map of all intended shot points along all survey lines to the county manager or designee prior to drilling and loading any shot holes. The location map shall be appropriately keyed with symbols and shall be on an aerial photographic base at a scale of one inch equals 400 feet.

    (2)

    The user shall provide, at his expense, an independent third party observer(s) who shall be thoroughly familiar with applicable county ordinances, the rules of the state fire marshal and current State of Florida department of natural resources geophysical rules and shall, when practical, meet all Florida state police board standards. The third party observer(s) shall witness the drilling, loading, shooting and plugging of all holes detonated by the user and shall maintain a shooting log book as required by the department of natural resources. In addition, no remedial operations to neutralize an undetonated shot hole shall take place without the observer(s) also witnessing the activity. The name, address and telephone number of the independent third party observer(s) shall be provided to the county manager or designee prior to the commencement of blasting operations. Where any requirement of this subsection is mandated by state statute or administrative rule as part of state licensing requirements, the applicant may comply with the requirements of this subsection by providing copies of materials or data supplied to the State of Florida in fulfillment of the state's requirement.

    (3)

    Appropriate signs shall be placed at intervals along the shot line to advise all persons of an explosive hazard.

    (4)

    Complete copies of files on the number of blasting caps used and pounds of explosives used on each shot line shall be provided to the county manager or designee.

    (5)

    Where necessary due to terrain or unusual geographic conditions, transportation to and from the blast site shall be provided by the user for any county official acting in their respective official capacities in performance of their duties that is required to visit the site for any purpose.

    (b)

    The following requirements shall be applicable subsequent to blasting operations:

    (1)

    Within 15 days after completion of each shot line, a survey base line and exact shot points must be established for future relocation of each shot hole. The survey must have a minimum closure of one to 5,000. Such survey shall be made in relation to the nearest section line or other appropriate line of demarcation so as to insure proper relocation of shot holes in the future. Legible copies of all field books and computations shall be submitted to and retained by the county manager or designee. In the event that survey data reveals that blasting has occurred at other than the permitted location, the county manager or designee is authorized to require an after-the-fact permit application for the area where the blasting has taken place and to require any and all actions by the user to comply with the intent and purpose of this article. The county manager or designee is further authorized, however, to waive the permit fee for an after-the-fact permit application where it is determined that the user has relied in good faith on inaccurate survey data or if the county manager or designee determines that specific site conditions render the fee inapplicable or unnecessary.

    (2)

    The user shall certify in writing that the State of Florida's Bureau of Geology's field office representative is satisfied that all owners on whose property blasting operations have occurred, have been properly restored including, but not limited to, removal of pin flags, wire and trash from the site, and that all detonated holes and ruts have been backfilled to surrounding grades.
