(3) Preblast notification plan. A plan outlining preblast public
notifications, structural inspections, and blast effect monitoring within
a specified distance of the blasting is required before the blasting permit
is issued.
(a) Separation distance. The distances from the blasting where
the notification, preblast structural inspection, and blast monitoring
is required must be determined by the scaled distance formulas described
below. Blasting will not be permitted until the notification and inspection
requirements are completed.
(b) Scaled distance formulas.
(i) The distance from the blast within which:
Notification of all occupied
structures is required: Da .= 90 w
Inspection of all occupied
structures is required: Db .= 75 w
Monitoring of selected
structures is required: Dc = 60 w
(ii) In the above formulas:
Da, Db, and Dc are the
actual distances in feet from the closest point in the blast.
W is the square root
of the maximum weight of the explosives in pounds detonated with
a minimum 8 millisecond from another detonation event.
(c) Notification letter. The preblast notification
must consist of a letter advising all residents within the distance
(specified in WAC 296-52-720 section 10 (3)(b)) of the blasts.
The letter must include the intent of the blasting program,
its anticipated impact on local residents, the proposed duration
of blasting activities, and provide telephone numbers for public
contact. Distribution of this notification must be made a minimum
of 7 days before the start of blasting. The source of the chart
is 121.8507, Bureau of Mines, U.S. Department of Interior, 1980.
(d) Preblast inspection. A preblast inspection of resident's
property must be offered to all residents within the distance
(specified in WAC 296-52-720 section 10 (3)(b) above) of the
blasting at no cost to the resident and will be preformed by
a qualified third party who isn't an employee of the contractor.
A copy of the individual inspection reports and a log of all
photos taken are to be provided to ____________________ (jurisdiction
name). Where inspections are not allowed by the resident or
aren't possible for other reasons, a certified letter must be
sent to the occupant/owner at the unsurveyed address advising
them of their right to a preblast inspection and the possible
consequences of denying an inspection. The preblast inspection
program for residences within the specified distance must be
complete 2 days prior to the start of blasting and the ____________________
(name of the proper administrative authority) should be notified.
(4) Blast-plan compliance inspections. Blast-plan compliance
inspections may be required for every blast until the operator
can demonstrate an ability to safely blast according to the blast
plan and control the extraneous effects of blasting such as flyrock,
noise/air blast, and ground vibration. If more than 2 blasting
inspections are required, an additional fee of ____________________
(insert dollar amount) per blast inspection will be assessed.
(5) Monitoring. All blasts which require monitoring by
section 10 (3)(b) are to be monitored using blast monitoring equipment
designed for the purpose and carrying a certificate of calibration
dated within the previous 12 months. The blast monitors must record
peak particle velocity and frequency in three orthogonal directions
and air over pressure. Monitored shots in which the pounds detonated
per an 8-millisecond time increment is less than ten pounds, one
blast monitor is required. When 10 or more pounds is detonated
per an 8-millisecond time interval, 2 or more blast monitors are
required. All blast-monitoring records are to be signed and submitted
to ____________________ (jurisdiction name) within 24 hours of
each blast.
(6) Maximum peak particle velocity. The maximum peak particle
velocity in any seismic trace at the dominant frequency allowed on any
residential, business or public structure designed for human occupancy
is to be determined by the chart in WAC 296-52-67065(1).
(7) Air blast. The maximum air blast over pressure permitted
at the closest residential, business or public structure designed
for human occupancy isn't to exceed 133 dBL @ 2.0 Hz hi pass system
per WAC 296-52-67065(3). The source of this regulation is 121.8485,
Bureau of Mines, U.S. Department of Interior, 1980.
(8) Utilities. Whenever blasting is being conducted in
close proximity to existing utilities, the utility owner must
be notified a minimum of 24 hours in advance of blasting.
(9) Blast report. A signed blast report, on a form approved
by the ____________________ (name of the proper administrative
authority) or their designee, needs to be filed with ____________________
(jurisdiction name) within 24 hours of the blast. The report must
include the following blast information:
(a) Date, time, and location of the blast
(b) Number of drill holes
(c) Maximum, minimum and average drill hole depth
(d) Drill hole diameter

time interval
(l) Type and size of any flyrock protection devices used, if any
(m) Comment regarding the outcomes of the blast.
(10) ____________________ (jurisdiction name) must be notified
immediately of any unplanned or unusual events that resulted from
