I551 Ver 3 Surry County Sub�ect Property NC Granite Corporat�on — Ararat River Pro�ect AFTER THE FACT Ararat River [030703 12 72 (4 5) C] REQUEST FOR MORE INFORMATION Dear Mr Moles On September 26 2011 the D�vision of Water Qual�ty (DWQ) received your After the Fact application dated September 23 2011 and Public Notice issued by the USACE on November 4 2011 and rece�ved by the DWQ on November 4 2011 to impact 540 linear feet of perennial stream to facilitate a water source for North Carolma Granite Corporat�on at the site The DWQ has determined that your application was mcomplete and/or provided maccurate �nformation as discussed below The DWQ w�ll requ�re addrtional information m order to process your application to impact protected wetlands and/or streams on the sub�ect property Therefore unless we rece�ve five copies of the additional information requested below we will place this proJect on hold as mcomplete until we receive this addit�onal mformat�on If we do not receive the requested mformation your pro�ect will be formally returned as mcomplete Please provide the followmg information so that we may contmue to review your pro�ect Add�tionat Informat�on Requested Please address the concerns below of the North Carolma Division of Water Resources as presented m J�m Mead s letter dated December 1 2011 to Monte Matthews w�th the USACE The quarry mtake �s located 4 r�ver m�les upstream of Mt Airy s wastewater treatment plant (WWTP) and the confluence with Lovtlls Creek The WWTP has a permitted discharge to the Ararat River of 7 mgd Lov�lls Creek �s a 303 d listed tributary of the Ararat River The Ararat River is 303 d l�sted for turb�dity in its lower 15 river mile reach to the Yadkm R�ver confluence This �nformation �s presented for cons�deration of possible cumulatrve impacts 2 The notice states that the quarry presently requ�res 1 75 m�llion gallon per day (mgd) or 2 7 cubic feet per second (cfs) to cont�nue operation Is thts value a daily

3 December 14 2011 It is unclear from the drawmgs how the in stream structures w�ll partition flow m the Ararat R�ver between the downstream flow by and the divers�on mto the quarry s reservoir Informat�on that would help clar�fy how the d�version and mtake funct�on mcludes • The elevation of the lip of the quarry s bank side mtake and the stream discharge associated with that elevat�on • The water surface elevation of the r�ver at the 7Q 10 flow • The rating for the amount of water conveyed through the mtake at d�fferent depths above �ts l�p • Water elevations should be prov�ded for cond�tions w�th the �nstream rock vanes installed It may be necessary to md�cate these elevat�ons at more than one location — for example at the mtake and for the flow by port�on of the channel 4 Based on preliminary DWR calculations the stated 2 7 cfs w�thdrawal slight(y exceeds the volume of water equiva(ent to 20%7Q10 See below NC USGS Station #02113850 ARARAT RNER AT ARARAT Da�ly

uses the 20% of 7Q10 value as a threshold to determine �f further evaluation of the unpacts on mstream flow and aquat�c habitat is needed This evaluarion could mclude a srte specific study to determine instream flow by requirements for operation of the intake It should be noted that the maximum mstantaneous w�thdrawal amount is used to calculate the percentage of 7Q10 wrthdrawn If the 2 7 mgd withdrawal is an average daily value and the instantaneous maximum withdrawal rate is higher then the 20% 7Q10 threshold would be more sigmficantly exceeded The appl�cant should provide mformation to help determine if a study to establish a flow by requirement is requ�red First they should contact the U S Geolog�cal Survey to obtain a formal estimate of the 7Q10 at the withdrawal location The application should also mclude an on site drought response plan and any water reuse/conservat�on efforts that would reduce the wrthdrawal amount when flows m the Ararat R�ver approach 7Q 10 drought

if reductions m the 7Q 10 flow at th�s upstream location at 65 square miles of dramage area would adversely affect ass�milat�ve capac�ty at the Mt Airy WWTP located farther downstream on the Ararat River 6 The applicant should provide a mamtenance plan to assure that the proposed mstallation and intake will function as proposed over t�me � NC Granite Corporation Page 3 of 3 December 14 2011
