SPS 307.44 SPS 307.44 Control of adverse effects.
SPS 307.44(1) (1)General requirements. Blasting shall be conducted so as to prevent injury and unreasonable annoyance to persons and damage to public or private property outside the controlled blasting site area.
SPS 307.44(2) (2)Flyrock. Flyrock traveling in the air or along the ground shall meet all of the following conditions:
SPS 307.44(2)(a) (a) Remain within the controlled blasting site area.
SPS 307.44(2)(b) (b) Not be cast more than one-half the distance to the nearest inhabited building within or outside of the controlled blasting site area.
SPS 307.44(3) (3)Airblast.
SPS 307.44(3)(a)(a) An airblast may not exceed 133 peak dB at the location of any dwelling, public building or place of employment outside the controlled blasting site area.
SPS 307.44(3)(b) (b) The blaster shall conduct monitoring of every blast to determine compliance with the airblast limit. The measuring system used shall have a lower-end flat frequency response of not more than 2 Hz and an upper-end flat frequency response of at least 200 Hz.
SPS 307.44(4) (4)Ground vibration.
SPS 307.44(4)(a)1.1. The maximum ground vibration at the location of any dwelling, public building or place of employment outside the controlled blasting site area shall be established in accordance with the blasting-level chart of par. (b).
SPS 307.44(4)(a)2. 2. All structures in the vicinity of the controlled blasting site area, not listed in subd. 1., such as water towers, pipelines and other utilities, tunnels, dams, impoundments and underground mines, shall be protected from damage by establishment by the blaster of a maximum allowable limit on the ground vibration. The blaster shall establish the limit after consulting with the owner of the structure.
SPS 307.44(4)(b) (b) The blaster shall use the ground vibration limits specified in Figure 7.44 to determine the maximum allowable ground vibration. Ground vibration shall be measured as the particle velocity. Particle velocity shall be recorded in 3 mutually perpendicular directions.
SPS 307.44(4)(c) (c) The blaster shall make and keep a seismograph record including both particle velocity and vibration frequency levels for each blast. The method of analysis shall be subject to discretionary review by the department.
SPS 307.44(4)(d) (d) For quarry operations, the blaster shall report any ground vibration levels to the department that are above 0.75 inch per second with frequencies less than 40 Hz.
SPS 307.44 Note Note: Local municipalities may have more restrictive regulations than the department.
