Re: Martin Marietta —Anticipated Bypass
Dear Mr. Vinson:
Pursuant to Part V, Section CA of General Permit No. NCG020000 (the "Permit"), this letteris to
advise the North Carolina Department of Environmental Quality (the "Department") of the
anticipated bypass of Martin Marietta's wastewater treatment systems at the Castle Hayne
Quarry (the "Quarry") — NPDES Permit COC No. NCG02001 0, which is due to river flooding
from Hurricane Florence. The flooding otthis location iathe result ofrivers upland from our
facility carrying water into the Quarry in connection with Hurricane Florence and the related
storm surge. It is currently anticipated that pumping in this manner will take up to six (8)
months. To safely and timely remove the water that has flooded the Quarry and to prevent
severe property damage, Martin Marietta is proposing to bypass its wastewater treatment works
at the Quarry and discharge directly from the Quarry to the Northeast Cape Fear River.
As aresult offlood waters from Hurricane Florence, approximately 7.GbiUiVOgaUuneofvvaterane
now held inthe Quarry. DnSeptember 17.2O18.Martin Marietta notified the Department nfthe
flood conditions akthe Quarry. Consistent with Section C.4.o.(1)(A)-(B)ofthe Permit, bypass of
the wastewater treatment works atthe Quarry iounavoidable toprevent severe property damage
due to prolonged flooding of the Quarry and the equipment located therein. Further, there iaDo
feasible alternative to the bypass as the volume ofwater in question is no great (up to 7.8 billion
gallons) that there is no way to process it through the normal treatment protocol in a time frame
that will not result inyears long effort. Such anextended submersion ofthis site would force the
Quarry to close and the equipment permanently located in the Quarry pits will be severely
damaged ordestroyed. Also, the enormous volume ofwater iomore than the pumps can handle
and will result inproperty damage ordestruction.
On October 4. 2018. Martin Marietta collected and analyzed e sample from the Quarry. The
results of that analysis are as follows:

Martin Marietta estimates that up to approximately 7.8 billion gallons of flood water will need to
be bypassed at a flow rate of up to approximately 27,000 gallons per minute (`gpm"). The actual
flow rate will vary depending on pumping and water level conditions (ie,, down time ho replenish
fuel, move the portable pump as the water levels drop, etc.). Martin Marietta will utilize the normal
treatment systems when these systems become available and will improve the discharge.
Consistent with Section C/4.b(1) of the Permit because the water |n question at the Quarry will
be returned to the Northeast Cape Fear River, which flooded the Quarry in the first instance, we
do not believe the water quality in the river will be materially adversely impacted by the anticipated
bypass.
Martin Marietta hereby requests that the Department approVe, in writing and on an
emergency and temporary basis, the staging of multiple pumps around the Quarry once
the river recedes and the conditions allow, and discharge of the flood waters directly from
the Quarry to the Northeast Cape Fear River until normal water levels are observed in the
Quarry.
Due to Martin Marietta's desire to start pumping in order to be responsive to customers' needs
for stone to help in repairs and rebuilding, including those of the North Carolina Department of
Transportation and a host of distressed municipalities, Martin Marietta is hoping for an
expedited resolution ofthis matter. Please let nleknow ifyou have any questions orifthere ia
any additional information we can provide toyou.
We appreciate your very prompt consideration ofthis matter.
Very truly yours,
