3 - Combined Response to ADI 5

July 6, 2021, ADI Letter #5
Response to questions concerning sound study, blasting, and post -reclamation lakes
1. Concerning the sound study your firm conducted for this modification, please provide the items
below:
a. The reasoning for using a slow response vs a fast response when recording with the
sound meters,
b. An explanation of how intrusive noises were differentiated from other background
noises, and
c. Data showing the blasts during the noise study were equivalent in size and location to
typical production blasts.
WSC Response
Responses to questions 1.a. and 1.b. were provided verbally during a TEAMS call between
NCDEMLR, Wake Stone Corporation, and WSP, USA Inc. on June 25, 2021. Erich Thalheimer of WSP has
summarized those responses in the attached memorandum sent to Sam Bratton, President of Wake
Stone Corporation on July 8, 2021.
WSC Response to Question 1.c.
Two typical production blasts occurred during the noise study data collection period. The first
blast occurred on November 18, 2020 at 1:3913M. This blast was located on the-40'MSL production bench
(42' bench height) and consisted of 30 blast holes. A total of 14,617 pounds of explosive agents were
utilized to generate approximately 16,000 tons of shot rock for production through the primary and
secondary plants. The blast event had a maximum duration/delay of 0.238 seconds. The second
production blast occurred on December 9, 2020 at 11:36AM. This blast was conducted on the-40'MSL
(42' bench height) production bench and consisted of 33 blast holes loaded with 16,335 pounds of
explosive agents. This blast generated 13,798 tons of stone for production through the primary and
secondary plants. The blast event had a maximum duration/delay of 0.223 seconds. Copies of the
complete blast reports, including wiring/delay diagrams are attached, as are weekly operating summaries
for the periods of time during which the blasts were conducted.
Both production blasts conducted during the noise study data collection were "typical" of
production blast events occurring at the Triangle Quarry. Wake Stone has previously provided five years
(CY 2015-2019) of blast data at the request of David Miller, State Mining Engineer. Comparison of
historical blast data and the blast reports for the two production blasts conducted during the noise study
period indicates that both blasts were similar in nature to production blasting that typically occurs at the
Triangle Quarry.

2. Reclamation Plan, item 2 of the application, requires that if you plan to reclaim portions of the
disturbed area as a lake, to supply an illustration of the location of the body(s) of water on the
reclamation map and provide a scaled cross-section(s) through the proposed body(s) of water.
Please supply a drawing to meet this requirement.
WSC Response to Question 2.
In response to question #2 above, Wake Stone has revised its Site Plan set to include Page 13 of
13. This drawing illustrates the anticipated post -mining Conceptual Reclamation Lakes and includes a
scaled cross-section/profile view illustrating existing ground, proposed ultimate grading, and anticipated
water surface elevations across the expansion pit and the original Triangle Quarry pit. The Site Plan set,
last -revised August 4, 2021, is included in this response package. This drawing set and the PLD Erosion
and Sediment Control Plan drawing set will constitute the final site development drawings to be
incorporated in the modified mining permit once issued.

Responses to DEMLR ADI Noise Questions 7/6/21
This memo is intended to respond to recent ADI questions from DEMLR dated 7-6-21 regarding the results
of our noise analysis supporting Wake Stone's expansion into Pit 2, and more specifically, our final report of
the same dated 3/12/21. The following answers were presented verbally during a conference call with
DEMLR on 6/25/21.
Question 1a) The reasoning for using a slow response vs a fast response when recording with the sound
meters.
Answer 1a) The RMS 'slow' time response for decibel levels was used throughout the entire study and
report for consistency with the majority of other noise criteria found for parklands (see Table
1 on page 8 of our report), and for the ability to directly compare "Existing" and "Future"
sound levels to determine the relative changes associated with expansion into Pit 2 (which
was the primary goal of the study to determine).
The nature of quarry noise, where machinery is operating constantly, is appropriately
averaged (Leq) using the 'slow' response. And the 'slow' response can be used to assess
loudest (Lmax) blasting noise for the ability to perform direct comparisons to existing levels
(see page 22 of our report). It is not possible to directly compare a sound level using 'slow'
to one using 'fast' for a transient event such as blasting.
Question 1b) An explanation of how intrusive noises were differentiated from other background noises.
Answerlb) The terms "intrusive" and "background" are not formally defined in acoustics and were not
relied upon in our study. In our study's case, Wake Stone has been operating out of Pit 1 for
decades, and thus was considered to be part of the existing ambient noise soundscape.
Ambient noise measurements were performed using many commonly used environmental
noise metrics such as Lmax, Leq, L1, L10, L50, L90, Lmin, and Ldn. Conservative noise model
predictions of Wake Stone's future noise contribution was performed using the energy -
average Leq metric for continuous noise sources and the Lmax metric to isolate blasting noise.
Professional Certification:
I hereby certify that this plan, specification, or report
was prepared or reviewed by me and that I am a duly
certified acoustical professional as recognized by the
Institute for Noise Control Engineering (INCE).
