Peak Particle Velocity Check:

(*rnax. limit in mining permit is: V = 1.0 ips)
Based on known distances from the blast to the seismograph and any additional location,
the expected vibration level can be estimated at the second location as follows:

(this is a very approximate method based upon numerous assumptions;
specific densities may vary greatly depending upon the type and manufacturer

REMARKS : holes ranged from 30'-43' used 36 as an average depth. long time to start loading, wait to get stemming out.
many holes not to depth most of these 27' deep, lots of hole issues blocked with rocks, most cleared up. paired
holes could not be drilled where they should have gone, because of ground conditions. seismograph did not get
the shot.

Janet,
Here is the information from our file regarding the blasting complaint of March 15, 2017 at Bamboo Road. I was at the
quarry performing an inspection on March 13, 2017, and found the site to be compliant. We have not received any
further blasting complaints since the March 15, 2017 event.
Thanks,
Matt

Matt,
This is the other blasting complaint that I was talking about today. I have not received hard copies (just email) of
blasting records, and we have not any records or information of a shot since March 15, 2017.

Subject: Radford Rock Quarry
Mr. Gantt,
Yesterday, March 15, 2017 around 4:30 p.m. the Radford Rock Quarry generated a blast that shook the
windows at our house at in the Sunny Knoll Subdivision. We don't think that the quarry
should use dynamite of that magnitude due to the closeness of our neighborhood.
Please make a record of this complaint and help us to prevent this from recurring. As I stated in an email to you
dated October 27, 2016, our neighborhood is very concerned and frightened about the dust, noise and damage
to our properties due to this closeness.
I would greatly appreciate it if you would send me any helpful information on what we can do.
Sincerely,

many holes not to depth most of these 27' deep, lots of hole issues blocked with rocks, most cleared up. paired
holes could not be drilled where they should have gone, because of ground conditions. seismograph did not get

If B or C, is there potential for oftsite damage? 0 Yes X No Explain: NA
19. Corrective measures needed and/or taken: Areas along the 50 -foot unexcavated buffer have been
stabilized with vegetation and white pine trees. The portion of the BREMCO access road within the 50 -foot
unexcavated buffer (on the south side of the mine) has been stabilized with base stone. A rip -rap ditch line
has been established along the north side of the BREMCO access road. The access to the mine off of Sunny
Knoll Acres Drive has been chained off. A good stand of vegetation is now present on the slopes of the
sediment skimmer basin located below the proposed plant and the proposed stockpile arm The lower
portion of the BREMCO access road off of Bamboo Road has also been covered with base stone. A new
drainage box has been installed at the inlet to the NCDOT culvert pipe under Bamboo Road. Mr. Cecile is in
the process of obtaining a metal grate from NCDOT to cover the top of the drainage box noted above.
Runoff from the upper portion of the BREMCO access road has been directed into the mining pit.
20. Other recommendations and comments: Meeting held on site with Mr. DJ Cecile and Mr. Derek
Goddard (BREC) at the request of Mr. Cecile to evaluate the condition of the 50 -foot unexcavated buffer on
the south and southeast portions of the mine. The white pine trees within the 50 -foot unexcavated buffer are
now roughly 4-5 feet tall. A good stand of volunteer vegetation (briars) is now present between the white
pine trees and the property boundary. Mr. Goddard has had the 50 -foot unexcavated buffer surveyed and
the buffer is now marked with wooden stakes and pink ribbons. Mining equipment, primarily dump trucks,
were parked outside of the 50 -foot unexcavated buffer. Trash and debris were being removed from the 50 -
foot buffer during the inspection. The lower portion of the quarry located on the west side of Bamboo Road
was als - o inspected. A small hole has been excavated on the outlet side of the drainage culvert under Bamboo
Road to capture any possible sediment running through the.culvert pipe. No flow was noted within the
channel below the NCDOT pipe during the inspection. Several stockpiles were noted on the west side of
Bamboo Road. Mr. Cecile indicated that the inventory was low at this time of year and will need to be
replaced in the spring. Travel areas on the west side of Bamboo Road had been stabilized with base stone.
