Tennessee Code Title 68. Health, Safety and Environmental Protection § 68-105-104

(a) In all blasting operations, except as otherwise provided in this chapter, the maximum ground vibration at a dwelling, public building, school, church, or commercial or institutional building normally occupied adjacent to the blasting site must not exceed the limitations specified in the following graph shown in Figure A to limit peak particle velocity based upon the frequency of the blast vibration:

Figure A

(b) Unless a blaster uses a seismograph to monitor a blast to ensure compliance with Figure A, the operation shall comply with the scaled distance equations shown in the following Table 1.

Key:

(c) Airblast resulting from blasting activities must not exceed one hundred forty decibels (140 dB) at the location of a dwelling, public building, school, church, or commercial or institutional building that is not owned or leased by the person engaged in the blasting operation, or on property for which the owner has not provided a written waiver to the person engaged in the blasting operation.

(d) In estimating the peak particle velocity at a particular position, the following equation must be used:

In the equation, V₀ is the maximum ground particle velocity at the seismograph, D₀ is the distance of the seismograph from the blasting, and D is the distance from the blast to the position in question and in the same general direction. The distance D₀ may not be greater than D, and D cannot be more than five (5) times D₀.

(e) Blasting operations at permanent sites are considered as being within the limits set forth in this section if at specified locations, on at least five (5) blasts, instrumentation has shown the peak particle velocity and frequency to be within the limits of Figure A. Periodic seismic monitoring must be employed to ensure compliance with applicable law.
