Department ofEnvironmental Quality, Division of Energy, Mineral and Land ReGanxeo 1012Mail Service Center Ra|eigh, NC 27696-1612 Re: Martin Marietta —Anticipated Bypass Pursuant to Part V, Section CA of General Permit No. NCG020000 (the "Permit"), this letter is to advise the North Carolina Department of Environmental Quality (the "Department") of the anticipated bvonao of Martin W1ahetbx'e wastewater treatment systems at the Belgrade Quarry (the "Quarry") — NPDES Permit COC No. NCG020005, which is due to river flooding from Hurricane Florence. The flooding at this location is the result of rivers 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 five (5) 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 tothe White Oak River. Asaresult of flood waters from Hurricane Florence, approximately34billion gallons of water are now held inthe Quarry. DnSeptember 17' 2018, Martin 01aheths notified the Department ofthe flood conditions atthe Quarry. Consistent with Section {|.4.o.(1)A\-(B)ofthe Permit, bypass nf the wastewater treatment works at the Quarry is unavoidable to prevent 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 of water in question is so great (up to 3.4 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 iemore than the pumps can handle and will result inproperty damage oFdestruction. On Dotober5. 2018. Martin Marietta collected and analyzed a sample from the Quarry. The results of that analysis are as follows: 271OWydUfRoad, Raleigh, NC276O7 t/919>783'4G57 t(919)7O3-4S36 ema|ijohn.giUan@mardnmadetta.00m www.mart|nmarietta.com October 12.2019 Page Parameter Result ornit Total Suspended Solids Not Detected 25 mq1I Martin Marietta estimates that Up to approximately 3.4 billion gallons of flood water will Deed to bebypassed ataflow rate ofuptoapproximately 30.000gaUonoperminute("opm"). The actual flow rate will vary depending on pumping and water level conditions (i.e., down time to 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 CA.b(l) of the Permit, because the water in question at the Quarry will be returned tothe White Oak River, which flooded the Quarry inthe first instance, we do not believe the water quality in the river will be materially adversely impacted by the anticipated bypass. Martin K0mdatto hereby requests that the Department approve, in writing and on an emergency and temporary basis, the staging mfmultiple pumps around the Quarry once the river recedes and the conditions allow, and discharge ofthe flood waters directly from the Quarry to the Northeast Cape Fear River until normal water levels are observed in the Quarry.
