(a) No person shall detonate an explosive device within the City without arranging and having present a seismologist, retained by the Director of Public Safety or his or her authorized representative, at each and every blast to record data produced by the same, as hereinafter provided.
(b) The Director may, from time to time, retain the services of a seismologist consultant for the purpose of carrying out the requirements of this chapter. The duties of such person shall include, but not be limited to, recording the following data as to each use of an explosive device of which he or she is notified:
(1) The identification of the instrument used;
(2) The name of the observer;
(3) The name of the interpreter;
(4) The distance of the recording station from the area of detonation;
(5) The recording station or its location in the structure;
(6) The maximum amplitudes for all components measured;
(7) The frequency of ground motion in cycles per second, if applicable;
(8) The maximum particle velocity for all components measured; and
(9) The maximum sound pressure level.
(c) Written notice of the exact time and place of the use of an explosive device shall be given to both the Director and the seismologist at least forty-eight hours before an explosion is detonated. Any seismologist retained by the Director or his or her designee shall attend all such detonations on the date and at the time and place when so notified. The seismologist shall issue written reports on each blasting event to the Director and shall indicate whether or not there was compliance with regulations and standards herein established. The seismologist shall have such other duties and responsibilities as shall be assigned to him or her by the Director or the Fire Chief and shall be paid from the per diem deposit fee required by Section 619.04(b). The Auditor is hereby authorized and directed to cause payment to be made to the seismologist from such deposits upon the presentation of invoices therefor, chargeable to the respective deposit to which the invoice is applicable, and upon approval of such invoices by the Director or the Fire Chief. Postponement of a blast for good cause, when approved by the Fire Chief, shall not result in an additional permit being required for the rescheduled blast, but the blaster shall comply with the notice requirements of this subsection in such event.
(d) Whoever violates any of the provisions of this section is guilty of a misdemeanor of the first degree for each offense. A separate offense shall be deemed committed each day during or on which a violation occurs or continues. The penalty shall be as provided in Section 698.02.
