• be blocked at least 10 minutes prior to the blast by a
manned vehicle having radio contact with the blasting
foreman to prevent the entrance of livestock or unau-
thorized personnel to the blasting area. The blast area
will be cleared by the blasting foreman. A siren sound-
ed intermittently for one minute will be used for the
blast caarning signal. The all clear signal will be a
siren sounded continuously for one minute. Blasting
will not be conducted at times different from those
announced in this notice except in emergency situations
where rain, lightning, or other atmospheric conditions
or operator or public safety concerns warrant unsched-
uled blasts.
(iv) The distance from the blast location to the
nearest dwelling, public building, school, church, community or
institutional building is at least 5,000 feet. The Operator will
work with the Division to determine the location and frequency of
monitoring to ensure compliance with the airblast standards con-
tained in Rule 4.08.6(a). The measuring systems used shall have
an upper-end flat-frequency response of at least 200 Hz.
(v) A preblasting survey is not required.
(vi) Unavoidable hazardous conditions which could
delay a scheduled blast include emergency situations where rain,
• lightning, or other atmospheric conditions or Operator or public
safety concerns warrant unscheduled blasts.
(vii) Blasting will be conducted in accordance with
the following equation. The maximum weight of explosives to be
detonated within any 8-millisecond period will be determined by
the formula W = (D/Dsl"2 where W = the maximum weight of explo-
sives, in pounds, that can be detonated in any 8-millisecond
period; D = the distance, in feet, from the blast to the nearest
dwelling, public building, school, church, community or institu-
tional building; and Ds = the scaled-distance factor cahich is 55
for distances from the blast site of 301 to 5000 feet and 65 for
5001 feet and beyond.
To meet the maximum allowable peak particle
velocity for ground vibration contained in Rule 4.08.4(101, for a
distance D from the blasting site of 5000 feet, the Operator will
not detonate more that 5,917 pounds of explosives within any 8-
millisecond period.
(viii) The applicant will contract with a third
party for the delivery, storage and use of all explosives. No
explosive storage area is planned for the permit area.
