Blasting
® The operator shall monitor each blast with a seismograph located at a distance
no farther than the closest off site regularly occupied structure not owned or
leased by the operator. A seismographic record including peak particle velocity, air
overpressure, and vibration frequency levels shall be kept for each blast (except as
provided under Sections 8B. and 8D. of this permit). The following blasting conditions
shall be observed by the mine operator to prevent hazard to persons and adjacent
property from surface blasting:
A. Ground Vibration With Monitoring•
11
In all blasting operations, the maximum peak particle velocity of any component
of ground motion shall not exceed twenty-five per cent of Figure 1 (below) at the
immediate location of any regularly occupied building outside of the permitted
area such as a dwelling house, church, school, or public, commercial or
institutional building.

Ground Vibration Without Monitoring:
In the event of seismograph malfunction or other condition which prevents
monitoring, blasting shall be conducted in accordance with the following
formulas:
W = (D/DS)2 Ds = D
Win
V = 160(Ds).l•6

Page 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).
D$ = Scaled distance factor.
V = Peak Particle Velocity (inches per second).
C. 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
area such as a dwelling house, church, school, or public, commercial or
institutional building, unless an alternate level based on the sensitivity of the
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 129peak
D. 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 (DNV0.33)-1.2
P = 20 x log (U/2.9xl0-9)
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).

RE: Blasting Complaint

Dear Mr. Jarrell:
The review has been completed on the shot records you previously submitted for the
February 9, 2007 through March 2, 2007 blasts at the North American Emerald Mine. Your
company has been found to be in compliance with the blasting conditions outlined in Mining
Permit No. 02-06. 1 have already notified the complainants, Ms. Kathy Johnson and Mr. William
Fred Walker, of our findings.
Based on the descriptions of the blasts you provided and on our review of the blast records,
it appears that the public's adverse reaction to your blasting operations may have been related to
airblast readings that were higher than those measured before and after the period in question.
While these readings were within the maximum limits specified in your mining permit for this site,
they were sufficiently high enough to produce citizen complaints. We recommend that your
company carefully review the blast records for the period in question and determine if any
adjustments can be made in your blasting procedures that could reduce the potential for future
complaints.
Thank you for your continued cooperation. If you should have any questions on the above,
please contact me at [phone].
Sincerely,
aa� �

Dear Ms. Johnson:
Our office has completed its review of North American Emerald Mine Inc.'s blasting
information, including blast reports and seismograph recordings, related to the February 9 through
March 2, 2007 blasts conducted at its North American Emerald Mine. It was found that North
American Emerald Mine Inc. was in compliance with the blasting requirements of its mining permit
during the period in question.
All peak particle velocities, a measurement of ground vibration with units in inches per
second (ips), were well below the maximum allowable limits specified in North American Emerald
Mine Inc.'s mining permit. More specifically, all recorded values were at or below A I ips at a
distance much closer than the closest offsite occupied structure (the location where compliance
with the permit limits is determined). According to extensive research by the U.S. Bureau of
Mines and others, particle velocities below 0.5 ips effectively eliminate the possibility of any
structural damage.
All airblast readings, a measurement of the atmospheric pressure wave (overpressure) with
units in psi or dBL, were also below the maximum allowable limits specified in the mining permit
and well below the U. S. Bureau of Mines' recognized level of 164 dBL for prevention of glass
breakage. A key point worth noting is that glass breakage occurs at much lower levels of
overpressure than structural damage, such as cracking plaster.
Thank you for your interest and patience in this matter. Hopefully I have answered your
concerns adequately. If you should have any additional questions or concerns, please contact me
at [phone]. Sincerely,

Dear Mr. Jarrell:
This office recently received a complaint directed at blasting practices conducted at the
above referenced quarry. According to the complainant, Ms. Kathy Johnson, the vibrations
produced from the blast at the North American Emerald Mine on February 17 and 24, 2007
caused her house to shake.
As provided in the mining permit for this site, you are requested to provide this office
duplicate copies of all shot records related to the blasts conducted on February 17 and 24,
2007, including any seismograph recordings made. Furthermore, please forward all shot
information for one production shoot conducted immediately before and one production shot
after the blasts in question for this office's review.
It is recommended that you discuss this matter with Ms. Johnson. Her address and
telephone number are as follows:
PO Box 264
Hiddenite, North Carolina 28636

look forward to receiving the requested information in the near future. Your continued
cooperation will be appreciated.
