Ethan,
Thank you for the phone call today.
We have applied for a mining permit for a rock quarry in Snow Camp NC near a Duke
Energy transmission line off of Quakenbush Rd. I have attached one plan sheet that has
the distance from your transmission line to the proposed pit and also the fully set of
plans for the proposed mine. I have also attached a GIS file with the locations and the
letter from DEQ asking about Duke Energy view on the proposed quarry location to the
transmission lines. Please let me know if you have any questions or concerns with the
location to the transmission lines.
I look forward to hearing from you.
Thanks, Chad

Ethan,
Based on the provided "Duke Power" sheet, the closest distance to the edge of our right of way is
776 feet. I have attached a document which specifically addresses blasting within our right of
way. This request is not within our right of way and the blasting is not within 700 feet of any of
our structures, so I believe all we need is confirmation that "the maximum particle velocity for
any blast shot shall not exceed 2.0 in/sec as measured at the base of the nearest structure to the
blast zone." Since the blasting is not within 700' of any structure we will not require
seismograph monitoring. I do not believe a formal blasting agreement is required.
I see an emergency access road proposed across our right of way, but I don't believe they
provided grading details. Is this road proposed at existing grade?
