Blasting Complaint
Dear Mr. Parr:
In response to your January 31,2023 notification of a blasting complaint for East Alamance Quarry,please
find attached shot records and seismograph readings for the previous shot, December 28, 2022 and the
shot on January 27, 2023. A subsequent shot has not occurred,so no records are available.
Additionally, the Fonville seismograph did not operate properly on December 28, 2022, so there is no
seismograph reading to include.
If you have any questions or need additional information please contact me at(919)783-4505 or via email
at [e-mail].
Sincerely,
Phillip N. Pressley, PE
Sr. Environmental Engineer
