Dear Mr Moles-
Reference the Department of the Army (DA) permit issued to you on September
14, 2012, which authorized the permanent placement of 600 cubic yards of fill material
and 1,680 cubic yards of granite within the Ararat River, and the dewatering of 540 linear
feet of stream channel to a side channel These impacts are associated with the long -tern
solution to supply water for future granite quarry operations. The project site is located
within the Ararat River, adjacent to the existing North Carolina Granite Corporation
Quarry, north of Mount Airy in Surry County, North Carolina The site is found at
Latitude and Longitude in Decimal Degrees of 36.510 °N and - 80.592 °W, and is within
the Yadkin River Basin (HUC 03040101)
Reference is also made to your letter dated January 29, 2013, requesting an
additional permitted impact within the existing holding pond Your request includes an
additional 0.014 acre of permanent open water impact from the installation of a closed
inlet structure and 30 linear feet of temporary open water impact from dewatering during
construction This structure will allow the holding pond to maintain a normal pool
elevation and maximize water recycling at the quarry. Plans showing this additional
impact were included with the request.
Lastly, reference an email from Mr Michael Wood of The Catena Group,
authorized agent, received on February 8, 2013, which indicated that installation of the
pipe through the 600 cubic yards of permitted fill would be completed on or before April
1, 2013. This pipe is intended to supply hydrology to the nearby side channel and
eliminates the need for additional compensatory mitigation. It is understood that you are
agreeable to modifying the permit condition to include this target date.
The Corps has completed the evaluation of your request and concurs with your
request for a change in impacts associated with your referenced DA permit, including the
change to plans as requested No compensatory mitigation is required for this
modification. In addition, Special Condition "e" is hereby modified to rea
FF19 1 8 2013
D NR - WAi ER (iUfa1 IT1

-2-
e) Installation of the 2" pipe will be completed on or before April 1, 2013.
The side channel below the 2" pipe discharge shall be measured for hydrologic
flow and visually monitored in February and August each year for two years post
construction This monitoring will be for loss of hydrologic function/flow and to
determine if the stream continues to provide aquatic life propagation and biological
integrity. Annual monitoring reports, photographic documentation, and measured
flow amounts shall be submitted to the Corps, Raleigh Field Office within 60 days
of each monitoring period. If flow is found to be less than the expected 26,500
gallons per day, compensatory mitigation may be required at the discretion of the
Corps.
It is understood that all other conditions of the permit, including the permit
expiration date, remain applicable. Should you have questions, contact Mr. Monte
Matthews, Raleigh Regulatory Field Office at telephone [phone], Extension 30.
Sincerely,
