In the event of seismograph malfunction or other condition which prevents
monitoring, blasting shall be conducted in accordance with the following
formulas:
W = (D/D S)2 Ds = D
W1/2
V = 160(Ds)-1.6
W = Maximum charge weight of explosives per delay period of 8.0 milliseconds
or more (pounds).
D = Distance from the blast site to the nearest inhabited building not owned or
leased by the mine operator (feet).
DS = Scaled distance factor.
V = Peak Particle Velocity (inches per second).
The peak particle velocity of any component shall not exceed 1.0 inch per
second, for the purposes of this Section.
Air blast With Monitoring:
Air blast overpressure resulting from surface blasting shall not exceed 129
decibels linear (dBL) as measured at the immediate location of any regularly
occupied building not owned or leased by the operator outside of the permitted

seismograph microphone as specified below is being used:
Lower Frequency Limit of Max Level,
Measuring System, in Hz in dBL
0. 1 Hz or lower -flat response 134 peak
2.0 Hz or lower -flat response 133 peak
6.0 Hz or lower -flat response 129 peak
Air blast Without Monitoring:
In the event of seismograph malfunction or other condition which prevents
monitoring, blasting shall be conducted in accordance with the following
formulas:
To convert U (psi) to P (dBL):
U = 82 (D/WO 33)-1.2

Page 7
P = 20 x log (U/2.9xl 0-9)
Confined Air blast/Overpressure (dBL)
for quarry situation:
A = P - 35
U = Unconfined air overpressure (pounds per square inch).
W = Maximum charge weight of explosives per delay period of 8.0 milliseconds
or more (pounds).
D = Distance from the blast site to the nearest inhabited building not owned or
leased by the mine operator (feet).
P = Unconfined air overpressure (decibels).
A = Air blast or air overpressure for typical quarry situations (decibels).
The air blast/overpressure shall not exceed 129 decibels, for the purposes of this
Section.
E. Record Keeping:
The operator shall maintain records on each individual blast describing: the total
number of holes; pattern of holes and delay of intervals; depth and size of holes;
type and total pounds of explosives; maximum pounds per delay interval; amount
of stemming and burden for each hole; blast location; distance from blast to
closest offsite regularly occupied structure; and weather conditions at the time of
the blast. Records shall be maintained at the permittee's mine office and copies
shall be provided to the Department upon request.
F. Excessive Ground Vibration/Air blast Reporting:
If ground vibration or Air blast limits are exceeded, the operator will immediately
report the event with causes and corrective actions to the Department. Use of
explosives at the blast site that produced the excessive reading shall cease until
corrective actions approved by the Department are taken. However, blasting
may occur in other approved areas within the permitted boundary. Authorization
to blast at the blast site may be granted at the time of the verbal reporting of the
high ground vibration or high air blast reading if the circumstances justify verbal
approval. Failure to report will constitute a permit violation.
G. Flyrock Prevention:
The operator shall take all reasonable precautions to ensure that flyrock is not
thrown beyond areas where the access is temporarily or permanently guarded by
the operator. Failure to take corrective measures to prevent flyrock and
repeated instances of flyrock shall be considered a violation of the Mining Permit.

Page 8
H. Flyrock Reporting:
Should flyrock occur beyond the permitted and guarded areas, the operator shall
immediately report the incident to the Department. Further use of explosives on
the mine site shall be suspended until the following actions have been taken:
A thorough investigation as to the cause(s) of the incident shall be
conducted.
