A. Use Of Explosives.
1. All
blasting shall be conducted during the daylight hours between sunrise
and sunset.
a. The
Building Inspector may specify more restrictive time periods based
on public requests or other relevant information according to the
need to adequately protect the public from adverse noise.
b. Blasting
may, however, be conducted during the nighttime hours between sunset
and sunrise if:
(1) A blast which has been prepared during the afternoon must be delayed
due to the occurrence of an unavoidable hazardous condition and cannot
be delayed until the next day because a potential safety hazard could
result that cannot be adequately mitigated; and
(2) In addition to the required warning signals, oral notices are provided
to persons within one-half (½) mile of the blasting site unless
persons have requested in writing they not be notified; and
(3) A complete written report on the blasting at night is filed by the
person conducting the blasting activities with the Building Inspector
not later than twenty-four (24) hours after the night blasting. The
request shall include a description in detail of the reasons for the
delay in blasting including why the blast was actually conducted,
the warning notices given, and a copy of the blast report required
by this Section.
2. Blasting
shall be conducted at times announced in a permittee's blasting schedule
except in those unavoidable hazardous situations identified in the
permit where operator safety or public safety requires unscheduled
detonation. Where no schedule is provided, the Building Inspector,
Police dispatch and Fire Chief shall be notified prior to any blasting.
3. During
blasting operations, warning and all clear signals of different character
that are audible within range of one-half (½) mile from the
point of the blast shall be given. Each person within the permit area
and each person who resides or regularly works within one-half (½)
mile of the permit area shall be notified of the meaning of the signals
through appropriate instructions. These instructions shall be periodically
delivered or otherwise communicated in a manner which can be reasonably
expected to inform such persons of the meaning of the signals.
4. Access
to an area subject to flyrock from blasting shall be regulated to
protect the public. Access to the area shall be controlled to prevent
the presence of unauthorized persons during blasting and until the
powderman/blaster who conducts the blasting activities has reasonably
determined the following:
a. That
no unusual circumstances, such as eminent slides or undetonated charges,
exist; and
b. That
access to and travel in or through the area can be safely resumed.
5. Except
where lesser distances are approved by the Building Inspector in the
pre-blast survey or the permit, based on seismic investigation or
other appropriate investigation, blasting shall not be conducted within
the following:
a. Fifty
(50) feet of any building used as a dwelling, school, church, hospital
or nursing facility; and
b. Fifty
(50) feet of facilities including, but not limited to, petroleum or
gas storage facilities, municipal water storage facilities, fluid
transmission pipelines, gas or oil collection lines or water and sewage
lines.
c. Pre-blast
surveys will be performed at the expense of the contractor/developer
or the permittee. Minimum qualifications for the person performing
a pre-blast survey shall be that the person has been employed in the
blasting field for a minimum of two (2) years.
d. Owner
of properties within fifty (50) feet of any blast site shall be given
written notice of the proposed blasting project and can accept or
reject the offer of a survey. Pre-blast surveys shall consist of a
minimum of 35mm photographs. However, in some cases additional documentation
such as technical reports and video tape may be required by the City.
6. In all
blasting operations, except as otherwise authorized in this Section,
the maximum peak particle velocity shall not exceed two (2) inch per
second at the location of any dwelling, public building, school building,
church or commercial or institutional building. Peak particle velocities
shall be recorded in three (3) mutually perpendicular directions.
The maximum peak particle velocity shall be the largest of any of
the three (3) measurements. The Building Inspector may reduce the
maximum peak particle velocity allowed if it is determined that a
lower standard is required because of density of population, land
use, age or type of structures in the area or frequency of blasts
or other factors.
7. Equation for maximum weight. The maximum weight of explosives
to be detonated within any eight (8) millisecond period may be determined
by the formula W = D/50(2), where "W" equals the maximum weight of
explosives in pounds that can be detonated in any eight (8) millisecond
period and "D" equals the distance in feet from the blast to the nearest
dwelling, school, church, or commercial or institutional building.
[Ord. No. 3548 §1, 1-22-2004]
All storage of explosives in excess of that amount required
for one (1) day's use shall be stored in an approved magazine in accordance
with the International Fire Code. The day box storage of that amount
required for one (1) day's use as approved in the blasting permit
application shall be in accordance with all City, State and Federal
regulations.
[Ord. No. 3548 §1, 1-22-2004]
