Title 25, Chapter 8, Section 3
( 25-8-3)
(a) The use of explosives for the purpose of blasting in the
neighborhood of any public highway, railroad, airport, dwelling
house, public building, school, church, commercial or institutional
building, or pipeline shall be done in accordance with this chapter
and the rules and regulations promulgated by the Commissioner. (b) In all blasting operations, except as otherwise provided in this
chapter, the maximum particle velocity of any component of ground
motion recorded on a three-component seismograph (where the
components -- transverse, vertical, and longitudinal -- are arranged
mutually perpendicular) shall not exceed two inches per second at
the location of any dwelling house, public building, school, church,
or commercial or institutional building normally occupied. (c) Blasting operations without instrumentation will be considered
as being within the limits set forth in this Code section if such
blasting operations are conducted in accordance with subsection (d)
of this Code section. (d) Any blasting operation may be conducted without reference to any
maximum amount or period provided by this Code section if the person
in charge of the blasting operation demonstrates by instrumentation
that maximum particle velocity of any component of the ground motion
does not exceed the limits provided in subsection (b) of this Code
section. (e) Instrumentation for determining particle velocity of ground
motion, as set forth in this chapter, shall be limited to devices
that conform with design criteria for portable seismographs as found
in the United States Bureau of Mines, RI-6487 and United States
Bureau of Mines Bulletin 656. The instrument should have calibration
traceable to the United States Bureau of Standards. The Commissioner
or his duly authorized agent may enter upon premises for the purpose
of observing any necessary instrumentation provided by this chapter. (f) When blasting operations, other than those conducted at a fixed
site as a part of any industry or business operated at the site, are
to be conducted within close proximity to a known pipeline, the
blaster or person in charge of the blasting operations shall take
reasonable precautionary measures for the protection of the line and
shall notify the owner of the line or his agent that the blastings
are intended. (g) Blasting operations shall not be conducted within close
proximity to any public highway unless reasonable precautionary
measures are taken to safeguard the public. (h) When blasting operations are conducted at the immediate location
of any dwelling house, public building, school, church, or
commercial or institutional building which would result in ground
vibrations having a particle velocity exceeding the limits provided
by this chapter, such blasting operations may proceed after the
receipt of written consent from the property owner or owners
affected. |
