SPS 307.41(1)(a)(a) At least 24 hours prior to initial blasting at a blast site, the blaster in charge shall make a reasonable effort to notify in writing or verbally all residents or owners of affected dwellings or other structures, as determined under sub.
(2), that a blasting operation is to begin. The blaster in charge shall offer to perform a preblasting survey for the residents or owners. If a resident or owner requests a copy of the preblasting survey, the blaster in charge shall provide a copy for not more than the actual cost of the copy within 48 hours of the request. Except as provided under
pars. (b) and
(c), only one initial preblasting survey is required for a blast site.
SPS 307.41(1)(b)
(b) The blaster in charge shall offer to perform a preblasting survey for the residents or owners of any dwelling or other structure that becomes an affected dwelling or other structure, as determined under
sub. (2), after the initial preblasting survey under
par. (a) is performed.
SPS 307.41(1)(c)
(c) The blaster in charge shall offer to perform a preblasting survey for the residents or owners of an affected dwelling or other structure, as determined under
sub. (2), constructed or renovated after the initial preblasting survey under
par. (a) is performed.
SPS 307.41 Note
Note: A preblasting survey provides a baseline record of the pre-existing condition of a structure against which the effects of blasting can be assessed, and it should include the interior and exterior of the buildings.
SPS 307.41(2)
(2) Affected buildings. Affected dwellings or other structures shall be determined based on the scaled-distance equation, W = (D/Ds)
2. Using a scaled-distance factor Ds of 55, affected dwellings or other structures shall be those located within the distance D of the controlled blasting site area for the weight per delay W of explosives to be used.
SPS 307.41 Note
Note: An example calculation to determine D is as follows: For 4 pounds of explosives, D = Ds(W)1/2 = 55 (4)1/2 = 110 feet.
