RE: Wake Stone Quarry Noise Study Protocol
Permit No. 92-10
Cary (Triangle) Quarry
Wake County
Neuse River Basin
Dear Bratton:
After carefully reviewing the proposed Wake Stone Quarry noise study protocol, the Mining
Program has the following comments:
1. Wake Stone will make all reasonable attempts to conduct two production shots as part
of normal operations during the monitoring period.
2. Please place short-term noise meters at the following locations:
i. At the two points where the property line cross the east and west ridgelines
caused by the stream feeding Foxcoft Lake.
ii. At the intersection of Old Reedy Creek Road and 1-40.
3. The short-term meters are required to monitor noise multiple times a day, during
periods of quarry operation and during periods when the quarry is not operating.
4. Upon completion of the report, a draft copy of the report will be provided to the Mining
Program for comment before the final is submitted.
5. Please provide production information for the two -week prior, the week of, and the two
weeks after the monitoring study for the following:
i. Primary Crusher:
A. Daily hours operated
B. Tons produced per day
ii. Finishing Yard:
A. Daily hours operated
B. Daily total tons produced
If these conditions are acceptable to you, please consider the protocol approved. If these
conditions are not acceptable, please contact either Brian Wrenn or me to discuss the matter.
As we have discussed, we would like to schedule a videoconference between your company,
the Mining Program, and your consultant to discuss the study and how the final report output
will be presented. The Mining Program staff will be in contact you shortly to set up this
videoconference.
