HOLTON PIT PORTION, USGS UPPER BROAD CREEK QUADRANGLE NCDENR SITE HYDROGEOLOGY INFORMATION DRAWINGS: (See Drawing Names Below) for J.C. Holion Pit N.C. Mining Permit 25-14 Located on Broad Creek Road - Holton Property prepared by Robed M. Chiles, P.E. Sheet i of 4: Existing Mine Plan Sheet 2 of 4: Modified Mine Plan (rev 1, 3-3-9) Sheet 3 of 4: Modified Reclamation Plan Sheet 4 of 4: Erosion Control Specifications iNTROIDUCTION This plan contains the pump operation and monitoring procedures for urine dewalering activities associated with the J.C. Holion Sand Pit operated by W.O. White, LLC, and located at 1 191 Brood Creek Road, in Craven County. PURPOSE In order fo facililale "dry" raining techniques, water is removed frorn the acfive portion of the excavation using a purnp(s). AQUIFER iNFORMATION According to the NCDENR, Division of Water Resources, Visual Hydrogeologic Framework, North Carolina Hydrogeologicai Database welasite, one, hydrogeologic unit is present within lire proposed maximum depth of the urine Bile, the Surficial aquifer. The lop of the Castle Layne confining unit is esfimaled to be 39 feet below the existing ground elevation, two feet steeper than the niaxinium minc depth. This information is based upon ifre approximate censer of the mine (laf 3zI.1 194N, long 76.959OW) and data recorded frorn NCDPNR boreholes nearest the mine. The NCDENR information reports an estimated ground surface elevation of 10 feet and the confining unit depth reported above is corrected to reflect an existing ground elevation of 12 feel. A copy 01 the visual hydrogeologic framework information is provided with this plan. PIEZOMETER (MOMTORING WELL) INFORMATION PURPOSE Piezomelers are used to monitor the extent and effect of proposed urine dewatering acfiviiies on subsurface water levels, and to establish a relalionshfp between the depressed subsurface waler levels and any resulting effects on the adjoining properties. No pfezomelers (monitoring wells) are currently proposed for fhe n*( dewalering ac-IMly, Adjoining property owners have expressed concern about potential impacts to the water level in their pond caused by mine dewatering activities. To miligate the effects of dewatering, an existing pump will be replaced by a float controlled pump to maintain the desired waiesr level in the adjoiner's pond using water from Pie mine pit. There are no known privale water supply wells in the area of the mine site PROPOSI=D CONSTRUCTION if required by any of the permitting agencies, piezometers will be installed in the following manner Each piezometer shall be constructed using a five foot minimurn length of 2" dianieler, .010 scof fed, PVC screen connected to the length of PVC well casing necessary to extend the lip of fhe screen to a depth of least 10 feel below the existing subsurface water levels. The pie70mefer well casing should extend at least one fool above the exisiing grade. A fine sand pack shall be installed from the bottom of the well to one foot above file lop of the screen. A two fool Mick benionife seal shall be placed directly over the sand pack. Native soils removed during well excavation may be used to fill the well to the existing ground elevation. A concrele pad or collar shall be constructed al the existing grade and centered on each well casing io secure the well pipe and provide a stable reference elevation for measuring file groundwater elevation. A removable protective sleeve, cap, or cover shall be installed to prevent direct entry of rafnwofer and to provide access for measuring the subsurface water level. PUMP INFORMATION The pump used at the mine site is a hydraulically coupled submersible pump with a maximum capacity of approximately 2,000 gallons per rninule. The purnp engine is positioned on the bank of the active mine pit, is hydraulically coupled to a float mounted, submersible pump located within the pit. The pump is used to create a water surface elevation that is a maximum depth of 35 feel below existing grade. PUMP OPERATIONS GENERAL Pumping will be employed as groundwater is encountered, and the pump will be ulilized as required to maintain a water surface elevation that is slightly lower than the excavation aclivifies to enablo the use of "dry" mining techniques. Continuous use of the proposed pump(s) at the reported capacity will result in 2,900,000 ga€Ions of water removed Irom the active excavation pit per day. Previous pumping octiviffes at the mile site indicate that after the desired water surface elevation is achieved, only A to 5 hours of pumping are typically required daily fo maintain the desired level. It is recciTimended thal purnping aclivifies be suspended whenever periods of inactivity al ►he mine will last longer than the lime required fo dewaler the active excavation, ADJOINER'S POND A separate, float -operated pump is being used at the mine site to maintain the desired waier level in the adjoining subdivision's pond located to the east of the mine site. The purnp is being provided to mitigate the effects of mine pit dewatering on the adjoining pond while dewatering activities are being ernployed. EXISTING EXCAVATION In order to limit the onlount of sediment carried oui of the mine excavation with mine water beirig removed, mine purnp(s) shall, if possible, be operated during hours when file excovator(s) are not operating. Whcn possible, mine dewatering shall be performed in advance of and to a depth greater than that of excavaiion activities to prevent the excavation activities frorn mixing soil particles with the water to be removed. The primary dewalor}ng pump(s) shall b0 located as far frar7S the excavation equipment and active disturbance as possible. Discharge from the dewatering pump(s) shall be directed into a water body formed in an inactive, separate portion of the existing excavation in order to provide a sediment removal function, 'the separation can be provided through soil dikes or floating filtration curtains. When an inactive, separate portion of the existing excavation is no longer avcA abe or is not removing sediment to the level required by issued permits, pumping shall be suspended unfif additional sedinlen't measures are installed. Additional measures may include, among others, the insiallaiior, of check dams within the exisling system of ditches, the use of a "dirt bag" filtration type device on the pump discharg6 line, file inslatiafton of an NCDENR standard sediment basin, the use of NCOENR approved chernicai treatments, and/or other such device(s), individually or colleclively, in order to provide the required sediment removal. PROPOSED EXCAVATION The proposed excavation shall remain physically separated from Hie existing excavalion by leaving an undisturbed soil dike between ifie two pits, Discharges from file Pump(s) dewatering the proposed excavation shall be directed into the west end of the completed existing excavation. The completed existing excavation shall p' erforn-) the function of a sediment basin during ` dewatering of the proposed excavation. Waier shall discharge from the east end of the cornpleIed existing excavation through file proposed outlet structure. Check dams(s) shall be installed in 11.)e existing system of ditches 10 ensure that a visible wafer level is maintained in the ditches bordering the wetland area. A pump can be used to withdraw water from the completed existing excavation and discharge if info the wetland area ditches as an alternative to installing check darns. r PUMP DISCHARGE Water discharged from the pump travels through the inactive portion of the mine excavation to the existing system of ditches and evenlually leaves the area of the mine site near the southeast corner of the permit boundary. From this point, the existing ditches,flow eastward approxnnately 2,800 feel toward Upper Broad Creek, a tributary of tine Neuse River. Upon approval of the December 2008 mining perrriii modification request, a discharge slructure wilt be installed in the soulh-east corner of the exisling excavation to replace the existing discharge point. Upon initiation of the proposed excavation, pump discharge will enter the western porlion of the completed exisling excavation and discharge through the proposed structure. MONITORING PLAN (PUMP) Pump monitoring is required for the Central Coastal Plain Capacliy Use Area Waier Use Permit and NPDES permit. Monitoring shall include type and number of pumps operating, fours operated, volurne withdrawn (gallons per day), depth of pump intake (below existing ground), water surface elevalion, and any additional information requested by the permitting agency, Monitoring shall be performed daily unless oiherwise direcied/ollowed by the permit ling agency. During pumping, wifhdfawal roles shall be assumed to equal previously indicated pump capacity unless actual measurements indicate otherwise. Withdrawal roles shall be reported according to the requirements dictated by the applicable permitting agency. Pump withdrawal role records shall be retained for a period of al least 5 years from the dale of measurement, unless otherwise indicated by permitting agencies. MONITORING PLAN (f IEZOMETERS) No piezomeiers are currently proposed. The permeable sands present in the mine apparently extend to and provide a hydrogeologic conneclion to a pond in the adjoining subdivision. The pond is located 200-250 feet horizontally from the easternmost portion of the mine and provides a similar function to a monitoring well. It required by a permilting agency; The monitoring wells shall be inslalled, allowed to stabilize, and existing subsurface water' e►evalions shall be recorded prior to changing the existing dewaiering practices. Subsurface wafer elevations shall be measured relative to a constant datum, such as top of the well casing. Subsurface wafer elevations in the monitoring wells shall be recorded daily throughouf the initial mine water drawdown and until a balance is achieved between water withdrawal activities and groundwater inflow. After o dewatering balance is achieved, subsurface water levels in the monitoring wells shall continue to be, recorded daily until no significant change is recorded. Water levels shalt be recorded weekly until no signiliconi change is recorded for two consecutive weeks. Once monitoring well levels achieve this level of stability, water level recording shall continue on a monthly basis. Changes in recording frequency may be subject to permitting agency approval. Permit requirements govern if they conflict wilh this monitoring schedule. Any time that the clewatering pump depth is increased to create a lower water Idvel in 11,1e. excavation, then piezometer monitoring shall revert to daily monitoring, Monitoring frequency can then he changed according to the plan indicated above, Monitoring results shall be recorded and reporled according to the requirements dicicied by the applicable permifling agency and shall be retained for a period of al least 5 years from the dcle of measurement, unless otherwise indicated by permitting agency. WETLANDS RECHARG1= AND MONITORING A delineation performed during April of 2009 identified an area of jurisdiciionai wetlands located near the proposed mine extension and the existing lake. The delineation was performed by Misters Paul Farley and Corey Novak of Land Management Group, Inc of Wilmington, NC and field verified by Ms. Tracey Wheeler of the US Army Corps of Engineers. The identified wetland area is indicated on the June 19, 2009 revision of the Modified Mine Plan, A fit#y-feef wide undisturbed buffer is also indicated where flee proposed mining activities and the wetland boundary are closest to each other. There is an existing ditch that marks the easternrnost edge of the identified weflond area. In order to offset any effect on the preserrce/supply of near -surface water within the wetland area during the temporary dewalering of the excavation site, a portion of the water discharged from the mine pump(s) will be diverted into the system of existing ditches that are adjacent to welland area. A nearly -full water level shall be maintained within the existing ditches, whether through the use of check dams, sufficient pump discharge volumes, or similar rneihods al all times while an artificially depressed water level is main lair within the excavation. Monitoring of fhe wetlands shall fake the form of daily visual inspections of existing plants io ensure that the vegelalion appears to remain healthy, as is seasonally appropriate, and to observe Ihaf there is neitlier an apparent absence nor over -abundance of water within the we [land area as compared with pre-dewalering conditions. As with any monitoring method, observatlons shall be recorded to include day, #ime, recent or current weather, observations, any findings that indicate a change in wafer supply should be made and any subsequent changes made to the water quantity being supplied. The proposed moniloring method is subject to approval and/or modification by the permitting agencies. CONTINGENCY PLAN In the event that the proposed mine dewatering has an adverse effect on any other offsife water body or the wetfond area adjoining the mine site, action shall be taken to counteract the effect. The action taken shalt be agreed upon by the owner of the effected water body, regulatory agency (if applicable), and the mine operator, MANDATORY PLAN REVISION The approved pump operation plan shall be revised if additional withdrawal capacity is required, or if it is determined that there are private water supply wells located in the vicinity of the mine and dewaiering activities are adversely effecting their production, or if mine dewatering adversely affects the nearby wetlands. this plan is also subject to those revisions determined necessary by the permitting ogencics.

Dear Mr. Edgerton: On behalf of our client, W.O,.While', 11C, and in response to your letter of July 10, 200Y, we provide those enclosures for your review and'app'oval. Enclosure 1 provides a copy of the revised written portion of.the proposed pump operation and monitoring plan for the Holton:f'if.. flie revisions include additional measures�,Io be taken fo reduce the volume of sediment carriecl;offsite by dewateiing pump discharges 6h'd reasures intended to maintain the existing hydrology within, the wetlands that are located next to th'e proposed mine expansion. The revisions are contained primarily in the Pump Operations section and'in the added Wetlands Recharge' and Monitoring section. The ericlosed partial copy does not include 1f1e-USES quadrangle, vicinify map, road map, or mine InctpS', as Ihese have not changed since our lasl subrriissian Within fhe existing'excavation section of the plan, a nurrilDer of possible measures are included, to be implemented cis needed, in order to achieve the sediment removal requVernents of the issued permits. The primary mechanism for achieving sediment removat,during the proposed excavation is to use the water, body formed in.the completed existing excavation a's a sediment basin, With dewaiering pump discharges entering of the west end and leaving the east end of the completed excavation, a rnininioni straight-line flow path of approximately 1 100 feet is provided as well as a length to wicffh rolio of approximately Three to one. The existing syst(,:rn of ditches onsite is connected to the ditch Ihat forms the eastern border of the delineated welland afea. The primary means for preserving the existing hydrology within the we'llonds is to divert water irorn the pump discharges and maintain an approxirnafely full water level in If7e existing ditches adjacent to the wetlands. There has been no visible surface water.wilhin the wefland area during any site visit, and the invert of the existing dilch along the east cadge was mostly dry also. While it is possible that previous mining activities have already artificially lowered fhe water levels to some extent, the Intention is to maintain fhe current conditions without artificially flooding the entire area.

Hollon Pit, N.C. 14ring Permit 25- 14, prepared by Robert M, Chiles, PE Dear Mr. Fdgerfon: On behalf of our client, W.O. Whife, CSC, we ptovide. this response to your letter of September 24, 2009. As we discussed during our last telephone conversation, we'laave prepared a drawing to depict the approximate groundrvafer-corie of depression -that will be created by dewate[ing the proposed mine expansion. The groundwater contours depicted in the drawing, provided as enclosure 1, are based upon reverse dislance-drawdown'inforn)aiion geherafed using.the INCDENR DWR soffwal-o. The values for transmissivily and storage -coefficient were genercited by. a distance-drawdown analysis based upon observations made at the I-loiton Pit during various stages of water removal in the existing niinc, The contours assume an initial groundwatersurface located at elevatibn 4 (recent survey data) or approximcfely 6 reef below the existing ground surface. Bdsed upon the approximate cone of depression, when the proposed mine,pil is dewatered to its maximum depth, the groundwaiersurface underneath the wetland area vw4l vary -from elevation 4 to elevation -5 feet,=indicating a maximum change of approximately 9 feet. When added to only the infcrm6fion about the mine dewatering's effect on the adjacent property owner's pond, this-indicates-thdt the proposed dewatering fn the new section of the mine will cause an uo cceptdble effbc:t- on the hydrologic conditions wilhin the wetland. As you have access to the same information and Gl.lg#ytical:fools,.lthis is probably the basis for the Statement in your letter that "it appears very.likely..tl'�crf Jhe devvatering activities have oI will degiode adjacent wetlands." On October 23, 2009 our office visited the site of the I-loifon Pit to funkier investigate the weitand area that N adjacent to the proposed mine expansion. During our site visit, we performed a survey to ideality the elevafions of the water surface in fhe existing pond on the Holton property and the ground surface in the wetland area. Because the pond is isolated, and its wafer level is not dependani upon a stream or other surface water feature, the woter surface in the pond is presumed to closely indicate ii re existing groundwater surface elevation. On the day of our site visit, our survey data indicated a waler surface elevation of 3,88 feet. The wefiand identified on the project site is a relatively flat area surrounded by raised features thai effectively create a shallow bowl. On the day of our site visit, our survey dafa indicated ground surface e€evasions of 8,11 and 8.15 feel of two locations within the wetland area. MECHANICAL. CI\'1L.

Edgedin Owing to the difference between the apparent ground water surface elevafion and the ground elevation of the wetland, two soil borings were advanced in the wetland area. The ground elevations within the wetland correspond with the locations of the two soil borings and both are indicated on the I drawing provided as enclosure 1. Both soil borings were advanced to a depth of four feet below the existing ground surface using a hand operated, three inch diameter, cylindrical ouger. The soils within the two borings were examined at six inch intervals and the findings are presented here as well as on the drawing. Aside from moisture contained in the soil itself, free water was not encountered in either boring. Depth Below Existing Ground Surface : Observations D to 12 inches : Organic soil, root mat (roots not exidized), and leaf litter. 12 to 24 inches ; Clayey sill or silty clay, with increasing clay content. black fine sandy silty clay. 24 to 36 inches; Black color changing to brown. Increasingly plastic clayey silt or silty clays, 36 to 42 inches; Bottom of clay, top of light grey/beige fine sandy silt. 42 to 48 inches: Sandy silt transitions to light tan fine sand, similar fe mason's sand, Observations made by myself and ,Mr. Pau(Fa.ley of 1-011d Management Group, Inc who performed the we#land delineation,. lead us to presume 111hof -the wetland area is dependant upon rainfall, and not groundwater to niaintain'its.liydroiogy. _.This presu,i,�ption is supported by the 18 to 24 inch thick clay layer underlying the wetldnd and th' -four feet of separation between the wetland ground surface and the apparent groundwater surface. Previous mine dewatering-actiilifies in the existing excavation lowered the water level in the adjoining land owner's pond, and your letter references fl-ris information. It is iniportaril to note fhat the adjoiner's pond had been'eXcavated to a depth where the pond bottom extended into the sarne layer of clean sands Thai cre being. excavated by. the rnining operation. TKe.porous nature of the sand layer created a significant hydrologic connection between the pond and the excavation, as evidenced by the impact on the pond's water level. Based upon fhe presence of fhe weiland, the-4 feet of separation between the wetland surface and the groundwater, and the,presence of the 18 fo 24 inch Thick clay €ayer, a similar hydrologic connection does not exist between lhe.wetfand and mirie' excavation. Your letter recommended establishing a "restrictive horizon°' -tom separate the dewvale'red aquifer from the wetland area. We conclude that such a restfrictivp h6[izon, is aready provided by ihe, clay layer discovered try the soil borings. . . . - . With the knowledge of the underlying claj%"layer, i# is our opinion that the proposed mine dewatering will have no effect on the wetland area. Accordingly, we propose no changes to the previously submitted pump operation and monitoring plan. The plan already contains provisions to provide supplemental wafer to the wefland perimeter and to monitor its planl life. it is our opinion that "a plan to reestablish the proper hydrology" of the wetland has became unnecessary in light of the new information provided by the soil borings. Should you require additional infomialion ar have any questions, please contact us your convenience. In the absence of furiher requests from you, we will look forward to the issuance of the requested permit, Very truly yours, ROBERT M, CHILES, P.E. Michael L, Rice, P,F, cc: W.

Sheet I of 4: Existing Mine Plan Sheet 2 of 4: Modified Mine Plan (rev t, 3-3-9) Sheet 3 of 4: Modified Reclamation Plan Sheet 4 of 4: Erosion Control Specifications INTRODUCTION This plan contains the pump operation and monitoring procedures for mine dewatering activities associated with the J.C. Hutlon Sand Pit operated by W.O. White, LLC, and located at 1 191 Broad Creek Road, in Craven County, PURPOSE In order to facilitate "dry" mining techniques, water is removed from the active portion of the excavation using a pumpjsj. AQUIFER INFORMATION According to the NCDENR, Division of Water Resources, Visual Hydrogeologic Framework, North Carolina Hydrogeologicaf Database website, one hydrogeologic unit is present within the proposed maximum depth of the mine site, the Surficial aquifer. The lop of the Castle Hayne confining unit is estimated to be 39 feet below the existing ground elevation, two feet deeper than the maximum mine depth. This information is based upon the approximate center of the mine (lat 34.1 194N,'ong 76,9590W) and data recorded from NCDENR boreholes nearest the mine. The NCDENR information reports an estimated ground surface elevation of 10 feel and the confining unit depth reported above is corrected to reflect an existing ground elevation of 12 feel. A copy of the visual hydrogeologic framework information is provided with this plan. NEZOMErER (MONITORING WELL) INFORMATION PURPOSE Plezometers are used to monitor the extent and effect of proposed mine dewaiering activities on subsurface water levels, and to establish a relationship between the depressed subsurface water levels and any resulting effects on the adjoining properties. No piezometers (monitoring wells) are currently proposed for the mine dewaiering activity, Adjoining property owners have expressed concern about potential impacts to the water level in their pond caused by mine dewaiering activities. To mitigate the effects of dewatering, an existing pump will be replaced by a float controlled pump to maintain the desired woter level in the adjoiner's pond rising water from the mine pit. There are no known private water supply wells in the area of the mine site. PROPOSED CONSTRUCTION If required by any of the permitting agencies, piezometers will be installed in the following manner: Each piezometer shall be constructed using a five foot minimum length of 2" diameter, .010 siotled, PVC screen connected to the length of PVC well casing necessary to extend the tip of the screen to a depth of least 10 feel below the existing subsurface water levels. The plezometer well casing should extend of least one foot above the existing grade. A fine sand pack shot( be installed from the bottom of the well to one foot above the top of the screen. A two foot thick bentonite seal shall be placed directly over the sand pack. Native soils removed during well excavation may be used to Fill the well to the existing ground elevation. A concrete pad or collar shall be constructed at the existing grade and centered on each well casing to secure the well pipe and provide a stable reference elevation for measuring the groundwater elevation. A removable protective sleeve, cap, or cover shall be installed to prevent direct entry of rainwater and to provide access for measuring the subsurface water level. PUMP INFORMATION The pump used ct the mine site is a hydraulically coupled submersible pump with a maximum capacity of approximately 2,000 gallons per minute. The pump engine is positioned on the bank of the active rnine pit, is hydroul€colly coupled to a float mounted, submersible pump located within the pit. The pump is used to create a water surface elevation that is a maximum depth of 35 feet below existing grade, PUMP OPERATIONS GENERAL Pumping will be employed as groundwater is encountered, and the pump will be uliiized as required to maintain a water surface elevation that is slightly lower than the excavation activities to enable; the use of "dry" mining techniques. Continuous use of the proposed pump(s) at the reported capacity will result in 2,900,000 gallons of water removed from the active excavation pit per day. Previous pumping activities at the mine site indicate that after the desired water surface elevation is achieved, only A to 5 hours cf pumping are typically required daily to maintain the desired level. It is recommended that pumping activities be suspended whenever periods of inactivity at the mine will last longer than the lime required to dewaler the active excavation, ADJOiNER'S POND A separate, f#oat-operated pump is being used at the mine site to maintain the desired water level in the adjoining subdivision's pond located to the east of the mine site. The pump is being provided to mitigate the effects of mine pit dewalering on the adjoining pond while dewalering activities are being employed. EXISTING EXCAVATION In order to limit the amount of sediment carried out of the mine excavation with mine water being removed, mine pump(s) shall, it possible, be operated during hours when the excavator(s) are not operating. When possible, mine dewatering shall be performed in advance of and to a depth greater than that of excavation activities to prevent the excavation activities from mixing soft particles with the water to be removed. The primary dewalering pump(s) shall be located as far from the excavation equipment and active disturbance as possible. Discharge from the dewaiering pump(s) shall be direcied into a water body formed in an inactive, separate portion of the existing excavation in order to provide a sediment removal function. The separation can be provided through soil dikes or floating filtration curtains. When an inactive, separate portion of the existing excavation is no longer available or is not removing sediment to the level required by issued permits, pumping shall be suspended until additional sediment measures are installed. Additional measures may include, among others, the insialfaiion of check dams within the existing system of ditches, the use of a "dirt bag" filtration type device on the pump discharge line, the installation of an NCDENR standard sediment basin, the use of NCDENR approved chemical treatments, and/or other such device(s), individually or collectively, in order to provide the required sediment removal. PROPOSED EXCAVATION the proposed excavation shall remain physically separated from the existing excavation by leaving an undisturbed soil dike between the two pits. Discharges from the pump{s) dewatering the proposed excavation shall be directed into the west end of the completed exisiing excavation. The completed existing excavation shall perform the function of a sediment basin during dewaiering of the proposed excavation, Water shall discharge from the east end of the completed existing excavation through the proposed outlet structure. Check doms(s) shall be installed to the existing system of ditches to ensure that a visible water level is maintained in the ditches bordering the wetland area. A pump can be used to withdraw water from the completed existing excavation and discharge it 'nlo the wetland area ditches as an alternative to installing check darns. PUMP DISCHARGE Water discharged from the pump travels through the inactive portion of the rnine excavation to the existing system of ditches and eventually leaves the area of the mine site near the southeast corner of the permit boundary. From this point, the existing ditches flow eastward approximately 2,800 feel toward Upper Broad Creek, a tributary of the Neuse River. Upon approval of the December 2008 mining permit modification request, a discharge structure will be installed in the south-east corner of the existing excavation to replace the existing discharge point, Upon initiation of the proposed excavation, pump discharge wifl enter the western portion of the completed existing excavation and discharge through the proposed stn-jcture. MONITORING PLAN (PUMP) Pump monitoring is required for the Central Coastal Plain Capacity Use Area Water Use Permit and NPDES permit. Monitoring shall include type and number of pumps operating, hours operated, volume withdrawn (gallons per day), depth of pump intake (below existing ground), water surface elevation, and any additional information requested by the permitting agency. Monitoring shall be performed daily unless otherwise direcied/allowed by the permitting agency. During pumping, withdrawal roles shall be assumed to equal previously indicated pump capacity unless actual measuremenis indicate otherwise. Withdrawal races shall be reported according to the requirernenis dictated by the applicable permitting agency. Pump withdrawal rate records shall be retained for a period of of least 5 years from the date of measurement, unless otherwise indicated by permitting agencies. MONITORING PLAN (PIEZOMETFRS) No piezometers are currently proposed. The permeable sands present in the mine apparently extend to and provide a hydrogeofogic connection to a pond in the adjoining subdivision. The pond is iocoted 200-250 feet horizontally from the easternmost portion of the mine and provides a similar function to a monitoring well. It required by a permitting agency; The monitoring wells shall be installed, allowed to stabilize, and existing subsurface water elevations shall be recorded prior to changing the existing dewalering practices. Subsurface water elevations shall be measured relative to a constant datum, such as top of the well casing. Subsurface water elevations in the monitoring wells shall be recorded daily throughout the initial mine wafer drawdown and until a balance is achieved between water withdrawal activifies and groundwater inflow. After a dewalering balance is achieved, subsurface water levels in the monitoring wells shall continue to be recorded daily until no significant change is recorded. Water levels shall be recorded weekly until no significant change is recorded for two consecutive weeks. Once monitoring well levels achieve this level of stability, wafer level recording shall continue on a monthly basis. Changes in recording frequency may be subject to permitting agency approval, Permit requirements govern if they conflict with this monitoring schedule. Any time that the dewatering pump depth is increased to create a lower water level .n the excavation, then piezometer monitoring shall revert to daily monitoring. Monitoring frequency can then be changed according to the plan indicated above. Monitoring results shall be recorded and reported according to the requirements dictaled by the applicable permitting agency and shall be retained for a period of of least 5 years from the dale of measurement, unless otherwise indicated by permitting agency. r 1 , WETLANDS RECHARGE AND MONITORING A delineation performed during April of 2009 identified an area of jurisdictional wetlands located near the proposed mine extension and the existing lake. The delineation was performed by Misters Paul Farley and Corey Novak of Land Management Group, Inc of Wilmington, NC and field verified by Ms. Tracey Wheeler of the US Army Corps of Engineers. The identified wetland area is indicated on the June t 9, 2009 revision of the Modified Mine Plan. A (iffy -feet wide undisturbed buffer is also indicated where the proposed mining activities and the wetland boundary are closest to each other. There is cm existing ditch that marks the easternmost edge of the identified wetland area. In order to offset any effect on the presence/supply of near -surface water within the wetland area during the temporary dewaiering of the excavation site, a portion of the water discharged from the mine pump(s) will be diverted into the system of existing ditches that are adjacent to wetland area. A nearly -full water Level shalt be maintained within the existing ditches, whether through fhe use of check dams, sufficient purnp discharge volumes, or similar methods at all times while an artificially depressed water level is maintained within the excavation. Monitoring of the wetlands shall take the form of daily visual inspections of existing plants to ensure that the vegetation appears to remain heatfhy, as is seasonally appropriate, and to observe that there is neither on apparent absence nor over -abundance of water within the wetland area as compared with pre-dewaiering conditions. As with any monitoring method, observations shall be recorded to include day, time, recent pr current weather, observations, any findings that indicate a change in water supply should be made and any subsequent changes made to the water quantify being supplied. The proposed monitoring method is subject to approval and/or modification by the permitting agencies. CONTINGENCY PLAN In the event that the proposed mine dewaiering has an adverse effect on any other offsite wafer body or the wetland area adjoining the mine site, action shall be taken to counteract the effect. The action taken shall be agreed Upon by the owner of the effected water body, regulatory agency (if applicable), and the mine operator. MANDATORY PLAN REVISION The approved pump operation plan shall be revised if additional withdrawal capacity is required, or it it is determined that there are private water supply wells located in the vicinity of the mine and dewaiering activities are adversely effecting their production, or if mine dewaiering adversely affects the nearby wetlands. This plan is also subject to those revisions determined necessary by the permitting agencies. 2"o SCHEDULE 40 PVC WELL CASING 0�W Z w -- Ln t 0 > —_ PVC END CAP EXISTING GRADE NATIVE SOIL FILL TO GROUND SURFACE 2-FOOT BENTONITE SEAL 0Z uj xC) U U Q IL o > 2 0 Q co Lo Q u Z �» w 0 0 m a PVC CAP ' I PIEZOMETER WELL DETAIL (TYP) INFORMATION (20Y ONLY T WASHINGTON t ��a . � C{ i.'- HOLitlt-f R} i R z"� > I^ .

The revisions are contained primarily in the Pump Operations section and'in the added Wetlands Recharge and Monitoring section. the enclosed partial copy does not include ffie USGs quadrangle, vicinity map, road neap, or mine maps,_ as fhese have not changed since our last submissionl' Within the existing "excavation section of the plan, a number of possible measures are incfuded, fo be implemenied as needed, in ord6r to achieve the sediment removal requirements of the issued permits. "the primary mechanism for achieving sediment removal.during the proposed excavation is to use the water body farmed in"the corr101eted existing excavation as a sediment basin. With dewatering pump discharges enlering at the west end and leaving the east end of the completed excavation, a minimum straight-line flow path of approximately 1;70Q feet is provided as well as a length to width ratio of approximately three to one. The existing system of ditches onsile is connected to the ditch that forms the eastern border of the delineated welland area. The primary rneans for preserving the exisfing hydrology within the wetlands is to divert water from the pump discharges and maintain an approximately full water level in the existing ditches adjacent to the wetlands. There has been no visible surface wafer.wilhin the wetland area during any site visit, and the invert of the existing ditch along the east edge was mostly dry also. While if is possible that previous mining activities have already artificially lowered the wafer levels to some exlenl, the intention is to maintain the current conditions wifhout artificiolfy flooding the entire area. hAFCHAPTCA1.

Holton Pit, N.C. Mining Pori -nit 25- 14, prepared by Robert M. Chiles, P!_ Dear Mr. Ecfgertan. On behalf of our client, W.O. White, UC, we provide. this response to your letter of September 24, 2009. As we discussed during our-ldst'telephone Conversation, we have prepared a drawing to depict the approximate groundwater cone of depression' will be created by dewatering the proposed rnine expansion. The groundwater contours depicted in the drawing, provided as enclosure 1, are based upon reverse distance-drawdown.'iiiforniation generated u0ig.the NCDENR bWR software. The values for transmissivity and storage -coefficient were generdted by -a distance-drawdown analysis based upon observations made at the Holton Pit during various stages of wafer removal in the existing mine. The contours assume an initial groundwater surface located at elevation 4 (recent survey data) or approximately 6 feet below the existing ground surface. Based upon the approximate cone of depression, when the proposed mine,pit is dewatered to its maximum depth, the groundwater surface underneath the wetland area will vary from elevation 4 to elevation -5 feet, -,indicating a maximum change of approximately 9 feet.: -When -added to only the inforn`Iafion about the rnine dewatering's effect on the adjacent property dwner's'porid, this.Indicates fhdt the proposed dewalering in the new section of the mine will cause an undccceptdBle effect on the hydrologic conditions within the wetland. As you have access to the same inf&mafion and a0gJytical`fo6ls,l`his is probably the basis for the statement in your letter that "it appears very likely..tf at the.dewaIering activities have or will degrade adjacent wetlands." On October 23, 2009 our office visited the site of the Holton Pit to further investigate the wetiand area that is adjacent to the proposed mine expansion. During our site visit, we performed a survey to identify the elevations of the water surface in the existing pond on the Holton property and the ground surface in the wetland area. Because the pond is isolated, and its water level is not dependant upon a stream or other surface water feature, the water surface in the pond is presumed to closely indicate the existing groundwater surface elevation. On the day of out, site visit, our survey data indicated a water surface elevation of 3.88 feet. The wetland identified on the project site is a relatively flat area surrounded by raised features that effectively create a shallow bowl. On the day of our site visit, our survey data indicated ground surface elevations of 8.11 and 8.15 feet at two locations within the wetland area. A4ECHANICA.L.

Edgc;fon- Owing to the difference between the apparent ground water surface elevation and the ground elevation 'of the wetfand, two soil borings were advanced in file wetland area. The ground elevations within the wetland correspond with the locations of the two soil borings and both are indicated on the drawing provided as enclosure 1. Both soil borings were advanced to a depth of four feet below the existing ground surface using a hand operated, three inch diameter, cylindrical auger. The soils within the two borings were examined at six inch intervals and the findings are presented here as well as on the drawing, Aside from moisture contained in the soil itself, free water was not encountered in either boring. Depth Below Existing Ground Surface : Observations Of o 12 inches : Organic soil, root mat (roots not oxidized), and leaf lifter. 12 to 24 inches: Clayey silt or silty clay, with increasing cloy content. Black fine sandy silty clay. 24 to 36 inches; Black color changing to brown. Increasingly plastic clayey sill or silty clays, 36 to 42 inches; Bottom of clay, top of light grey/beige fine sandy silt. 42 to 48 inches: Sandy silt transitions to light tan tine sand, similar to mason's sand. Observations made by myself and Mr. Paul, Farley of Lariat Management Group, Inc who performed the wetland delineation -lead us to presume that the wetland area is dependant upon raintall, and not groundwater to maintain its.hydrology.-._This presu.mpfion is supported by the 18 Jo 24 inch thick clay layer underlying the wetiOnd and tfi6-.four feet of separation between fhe, wetland ground surface and the apparent groundwater surface. Previous mine dewatering-acfivities in the existing excavation -lowered the water level in the adjoining land owner's pond.. and your letter references this information. It is important to note that the adjoine-'s pond had been*ekcavated to a depth where the pond bottom extended into the same layer of clean sands that are being. excavated by. the mining operation. The -porous nature of the sand layer created a significant hydrologic connection between the pond and the excavation, as evidenced by the impact on the pond's water level. Based upon the presence of the wetland, the-4 feet of separation between the wetland surface and the groundwater, and the,presence of the 18 to 24 inch thick clay layer, a similar hydrologic connection does not exist between the -wetland and the'propQ5—dd mir'e'excavation. Your letter recommended establishing a "restricfive,hori?on:'•to separate the dewatared aquifer from the wetland area. We conclude that such a restrictive horizon is a_ rready provided by the clay layer discovered by the soil borings. ._ With the knowledge of the underlying clay lays"r, it is our opinion that the proposed mine dewatering will have no effect on the wetland area. Accordingly, we propose no changes to the previously submitted pump operation and monitoring plan. The plan already confains provisions to provide supplemental water to the wetland perimeter and to monitor its plant life. It is our opinion that "a plan to reestablish the proper hydrology" of the wetland has become unnecessary in light of the new information provided by the soil borings. Should you require additional information or have any questions, please contact us your convenience. In the absence of further requests from you, we will look forward to the issuance of the requested permit, Very truly yours, ......• -ROBERT M. CHILES, P.E., Michael L.

Holton Pit - Dewatering Operatio Craven County The Division of Water Quality's Washington Regional Office (WaRO) on'July 10, 2009 requested additional information regarding the Operation and Maintenance Plan (OMP) required by NCG020699. Your response was received on August 11, 2009 and has been determined to be incomplete. The OMP must be approved by the WaRO prior to any mine expansion dewatering. Non -Compliance with permit NCG020699 may subject you to enforcement actions in accordance with North Carolina General Statutes 143-215.6. Civil penalties of up to $25,000 per day, per violation, may be assessed. The WaRO has concerns regarding the degradation of adjacent wetlands from the proposed dewatering of your mine. It is our understanding that the mine dewatering activities have resulted in the water level lowering of an adjacent property owner's pond and that a satisfactory ending was achieved. It therefore appears very likely that the dewatering activities have or will degrade adjacent wetlands. The North Carolina Administrative Code for Wetland Standards, 15A NCAC 02B .0231(b)(5), requires that, "Hydrologic conditions necessary to support the biological and physical characteristics naturally present in wetlands shall be protected to prevent adverse impacts," related to several items including, "Water levels or elevations." You may want to consider using hydogeologic predictive calculations to establish the limits of the "cone of depression", and/or the establishment of a restrictive horizon separating the dewatered aquifer from the area wetlands. This information has been used with other OMP's on similar projects. However, if in fact this methodology demonstrates the wetlands will be degraded, a plan to reestablish the proper hydrology will be required in the OMP.

The primary means for preserving the existing hydrology within the wetlands is to divert water from the pump discharges and maintain an approximately full water level in the existing ditches adjacent to the wetlands. There has been no visible surface water within the wetland area during any site visit, and the invert of the existing ditch along the east edge was mostly dry also. While it is possible that previous mining activities have already artificially lowered the water levels to some extent, the intention is to maintain the current conditions without artificially flooding the entire area.',.- AUG 1 1 2009 MECHANICAL, CIVIL, AND MARINE ENGINEERING MARINE HYDROGRAPHIC AND LAND SURVEYS COMMERCIAL, INDUSTRIAL, MARINE, AND RAILROAD FACILITIES DESIGN FORENSIC ENGINEERING AND FAILURE ANALYSIS BOUNDARY SURVEYS AND MAPPING SERVICE N I Robert M.

Holton Sand Pit operated by W.O. White, LLC, and located at 1 191 Broad Creek Road, in Craven County. PURPOSE In order to facilitate "dry" mining techniques, water is removed from the active portion of the excavation using a pump(s). AQUIFER INFORMATION According to the NCDENR, Division of Water Resources, Visual Hydrogeologic Framework, North Carolina Hydrogeological Database website, one hydrogeologic unit is present within the proposed maximum depth of the mine site, the Surficial aquifer. The top of the Castle Hayne confining unit is estimated to be 39 feet below the existing ground elevation, two feet deeper than the maximum mine depth. This information is based upon the approximate center of the mine (lat 34.1 194N, long 76.9590W) and data recorded from NCDENR boreholes nearest the mine. The NCDENR information reports an estimated ground surface elevation of 10 feet and the confining unit depth reported above is corrected to reflect an existing ground elevation of 12 feet, A copy of the visual hydrogeologic framework information is provided with this plan. PIEZOMETER (MONITORING WELL) INFORMATION PURPOSE Piezometers are used to monitor the extent and effect of proposed mine dewatering activities on subsurface water levels, and to establish a relationship between the depressed subsurface water levels and any resulting effects on the adjoining properties. No piezometers (monitoring wells) are currently proposed for the mine dewatering activity. Adjoining property owners have expressed concern about potential impacts to the water level in their pond caused by mine dewatering activities. To mitigate the effects of dewatering, an existing pump will be replaced by a float controlled pump to maintain the desired water level in the adjoiner's pond using water from the mine pit. There are no known private water supply wells in the area of the mine site. PROPOSED CONSTRUCTION If required by any of the permitting agencies, piezometers will be installed in the following manner: Each piezometer shall be constructed using a five foot minimum length of 2" diameter, .010 slotted, PVC screen connected to the length of PVC well casing necessary to extend the tip of the screen to a depth at least 10 feet below the existing subsurface water levels. The piezometer well casing should extend at least one foot above the existing grade. A fine sand pack shall be installed from the bottom of fhe well to one foot above the top of the screen. A two foot thick bentonite seal shall be placed directly over the sand pack. Native soils removed during well excavation may be used to fill the well to the existing ground elevation. A concrete pad or collar shall be constructed at the existing grade and centered on each well casing to secure the well pipe and provide a stable reference elevation for measuring the groundwater elevation. A removable protective sleeve, cap, or cover shall be installed to prevent direct entry of rainwater and to provide access for measuring the subsurface water level. PUMP INFORMATION The pump used at the mine site is a hydraulically coupled submersible pump with a maximum capacity of approximately 2,000 gallons per minute. The pump engine is positioned on the bank of the active mine pit, is hydraulically coupled to a float mounted, submersible pump located within the pit. The pump is used to create a water surface elevation that is a maximum depth of.35-feet below_existing,graffe. PUMP OPERATIONS GENERAL Pumping will be employed as groundwater is encountered, and the pump will be utilized as required to maintain a water surface elevation that is slightly lower than the excavation activities to enable the use of "dry" mining techniques. Continuous use of the proposed pump(s) at the reported capacity will result inc2-900,000tgoIle ns of water removed from the active excavation pit per-dayt3 Previous pumping activities at the mine site indicate that after=the_desired,water surface-elevation;is.� achieved; only�4=to:�5 hours:of,purnping_are typically-requi.r_ed.dailysto maintain the desired level. It is_recommendedrthot pumping activities be suspended whenever periods of inactivity at the mine will last longer than the time required to dewater the active excavation. ADJOINER'S POND A separate, float -operated pump is being used at the mine site to maintain the desired water level in the adjoining subdivision's pond located io the east of the mine site. The pump is being provided to mitigate the effects of mine pit dewatering on the adjoining pond while dewatering activities are being emp#oyed. EXISTING EXCAVATION In order to limit the amount of sediment carried out of the mine excavation with mine water being removed, mine pum{ (s) shall, if possible, be operated during hours when the excavator(s) are not operating. Whenlpossibiermine dewatering s[,Ulrbe performed in advance of and to a depth greater than that of excavation activities to prevent the excavation activities from mixing soil particles with the water to be removed. The primary dewatering purnp(s) shall be located as far from the excavation equipment and active disturbance as possible. Discharge from the dewatering pump(s) �shdll be directed into a water body formed in an inactive, separate pardon of the existing excavation in order to provide a sediment removal function. The separation can be provided through soil dikes or floating filtration curtains. When an inactive, separate portion of the existing excavation is no longer available or is not removing sediment to the level required by issued permits, pumping shall be suspended until additional sediment measures are installed. Additional measures may include, among others, the installation of check dams within the existing system of ditches, the use of a "dirt bag" filtration type device on the pump discharge sine, the installation of an NCDENR standard sediment basin, the use of NCDENR approved chemical treatments, and/or other such device(s), individually or collectively, in order to provide the required sediment removal. PROPOSED EXCAVATION The proposed excavation shall remain physically separated from the existing excavation by leaving an undisturbed soil dike between the two pits. Discharges from the pumps) dewatering the proposed excavation shall be directed into the west end of the completed existing excavation. The completed existing excavation shall perform the function of a sediment basin during dewatering of the proposed excavation. Water shall discharge from the east end of the completed existing excavation through the proposed outlet structure. Check:dams(s)cshall,be=installed:in-then: existing:sysiem-_qi di€ches;to:ensure-that_a_visible=water.-level:is,maintained:in=the=ditches:bordering, the:wetland,area. A pump can be used to withdraw water from the completed existing excavation and discharge it into the wetland area ditches as an alternative to installing check dams. PUMP DISCHARGE Water discharged from the pump travels through the inactive portion of the mine excavation to the existing system of ditches and eventually leaves the area of the mine site near the southeast corner of the permit boundary. From this point, the existing ditches -flow eastward approximately 2,800 feet toward Upper Broad Creek, a tributary of the Neuse River. Upon approval of the December 2008 mining permit modification request, a discharge structure will be installed in the south-easi corner of the existing excavation to replace the existing discharge point. Upon initiation of the proposed excavation, pump discharge will enter the western portion of the completed existing excavation and discharge through the proposed structure. MONITORING PLAN (PUMP) Pump monitoring is required for the Central Coastal Plain Capacity Use Area Water Use Permit and NPDES permit. Monitoring shall include type and number of pumps operating, hours operated, volume withdrawn (gallons per day), depth of pump intake (below existing ground), water surface elevation, and any additional information requested by the permitting agency. Monitoring shall be performed daily unless otherwise directed/allowed by the permitting agency. During pumping, withdrawal rates shall be assumed to equal previously indicated pump capacity unless actual measurements indicate otherwise. Withdrawal:ratestsholl-be-rreported-according=to=the:requirerrments.`dicfated:by the applicable p� itting-agency. Pump withdrawal rate records shall be retained for a period of at least 5 years from the date of measurement, unless otherwise indicated by permitting agencies. MONITORING PLAN (PIEZOMETERS) No piezometers are currently proposed. The permeable sands present in the mine apparently extend to and provide a hydrogeoiogic connection to a pond in the adjoining subdivision. The:pond is located 200-250 feet horizontally from the easternmost portion of the mine and provides:a similar-''.function-to-a=monitoring well. If required by a permitting agency; The monitoring wells shall be installed, allowed to stabilize, and existing subsurface water elevations shall be recorded prior to changing the existing dewatering practices. Subsurface water elevations shall be measured relative to a constant datum, such as top of the well casing. Subsurface water elevations in the monitoring wells shall be recorded daily throughout the initial mine water drawdown and until a balance is achieved between water withdrawal activities and groundwater inflow. After a dewatering balance is achieved, subsurface water levels in the monitoring wells shall continue to be recorded daily until no significant change is recorded. Water levels shall be recorded weekly until no significant change is recorded for two consecutive weeks. Once monitoring well levels achieve this level of stability, water level recording shall continue on a monthly basis. Changes in recording frequency may be subject to permitting agency approval. Permit requirements govern if they conflict with this monitoring schedule. Any time that the dewatering pump depth is increased to create a lower water level in the excavation, then piezometer monitoring shall revert to daily monitoring. Moniioring frequency can then be changed according to the plan indicated above. Monitoring results shall be recorded and reported according to the requirements dictated by the applicable permitting agency and shal{ be retained for a period of at least 5 years from the date of measurement, unless otherwise indicated by permitting agency. WETLANDS RECHARGE AND MONITORING A delineation performed during April of 2009 identified an area of jurisdictional wetlands located near the proposed mine extension and the existing lake. The delineation was performed by Misters Paul Farley and Corey Novak of Land Management Group, Inc of Wilmington, NC and field verified by Ms. Tracey Wheeler of the US Army Corps of Engineers. The identified wetland area is indicated on the June 19, 2009 revision of the Modified Mine Pion. A fifty -feet wide undisturbed buffer's also indicated where the proposed mining activities and the wetland boundary are closest to each other. There is an existing ditch that marks the easternmost edge of the identified wetland area. In order to offset any effect on the presence/supply of near -surface water within the wetland area during the temporary dewatering of the excavation site, a portion of the water discharged from the mine pump(s) will be diverted into the system of existing ditches that are adjacent to wetland area. A nearly -full water level shall be maintained within the existing ditches, whether through the use of check dams, sufficient pump discharge volumes, or similar methods at all times while an artificially depressed water level is maintained within the excavation. Monitoring of the wetlands shall take the form of daily visual inspections of existing plants to ensure that the vegetation appears to remain healthy, as is seasonally appropriate, and to observe that there is neither an apparent absence nor over -abundance of water within the wetland area as compared with pre-dewatering conditions. As with any monitoring method, observations shall be recorded to include day, time, recent or current weather, observations, any findings that indicate a change in water supply should be made and any subsequent changes made to the water quantity being supplied. The proposed monitoring method is subject to approval and/or modification by the permitting agencies. CONTINGENCY PLAN In the event that the proposed mine dewatering has an adverse effect on any other offsite water body or the wetland area adjoining the mine site, action shall be taken to counteract the effect. The action taken shall be agreed upon by the owner of the effected water body, regulatory agency (if applicable), and the mine operator. MANDATORY PLAN REVISION The approved pump operation plan shall be revised if additional withdrawal capacity is required, or if it is defermined that there are private water supply wells located in the vicinity of the mine and dewatering activities are adversely effecting their production, or if mine dewatering adversely affects the nearby wetlands. This plan is also subject to those revisions determined necessary by the permitting agencies. 2"0 SCHEDULE 40 PVC WELL CASING N in— O Z — U IJ La Z — — .:•. — -1 0 ; Y— �.

General Permit No. NCG020699 Inadequate Operation and Maintenance Plan/ Additional Information Requested J. C. Holton Pit — Dewatering Operations Plan Craven County The Division of Water Quality's Washington Regional Office (WaRO) received the revised plan, which included the wetland delineation on July 1, 2009. The requested additional information was added to the Operation and Maintenance Plan (O&M) for the subject mine. The O&M was reviewed and has been determined as incomplete. The General Mine Dewatering Permit (NCG02) application is being processed in the Division of Water Quality's Raleigh Central Office (CO). Upon permit issuance (NCG020699), an APPROVED O&M will be required within 60 days of receipt of the permit. The O&M must be approved by the WaRO in order to remain compliant with the permit_ Non -Compliance may subject you to appropriate enforcement actions in accordance with North Carolina General Statutes 143-215.6. Civil penalties of up to $25,000 per day per violation may be assessed for failure to comply with a permit required by North Carolina General Statute 143-215.1. Also, no mine expansion dewatering is allowable prior to O&M approval. The WaRO has concerns about the proximity of the mining operation to the wetland area, and requests that you provide adequate engineering documentation to ensure that there will be no wetland impacts from this mine. The North Carolina Administrative Code includes Wetland Standards, 15A NCAC 02B .0231(b)(5), requiring that, "Hydrologic conditions necessary to support the biological and physical characteristics naturally present in wetlands shall be protected to prevent adverse impacts," related to several items including, "Water levels or elevations." Because this mine is located adjacent to wetlands, engineering calculations are necessary to ensure compliance with the Administrative Code. The O&M is a requirement of Part III Section C of the NCG02. The permit requires that the plan include, at a minimum: • "Groundwater monitoring strategies to demonstrate the effect of pumping and, as necessary, establish the pumping regime necessary to reduce impacts," and North Carolina Division of Water Quality Internet: www,ncwaterauality,,ora 943 Washington Square Mall Phone: (252) 946-6461 Washington, NC 27669 FAX: (252) 946-9215 An Equal Opportunity/Affirmative Action Employer — 50% Recycled110% Post Consumer Paper NorthCarolina naturally • "Detailed plans to maintain the surrounding hydrology and the respective monitoring to demonstrate compliance." Part III Section A of the NCG02 requires, at a minimum: • Appropriate Best Management Practices (BMPs) shall be used to divert, infiltrate, reuse or otherwise manage stormwater runoff and wastewater discharges. The O&M must also provide sufficient details to present all areas and stages of the project. Some of these areas are labeled as the Final Checklist on page 6 of 7 of the NCG02 application and are as follows: • Site map with wetlands, ditches, well placements, borrow areas, overburden storage, stormwater controls/BMPs, vehicle maintenance areas, settling basins, product process area, and access roads. • Well information (design, depths, maintenance) • Physical monitoring for the wetlands areas • Settling pond sizing information, if applicable • Level spreader design, if applicable • Details about dewatering method • Description of measures to prevent erosion and flooding The information set forth in this letter, is presented as guidance to assist as the O&M is revised. Include other areas or stages of the operation as necessary to present the overall project. My contact number is (252) 948-3955 or email thom.edgerton@ncdenr.gov with any questions.

As a result of a discussion -with -Mr. -Blake Rouse. of -the- Division. of-Waier-i? sources, we have revised the pump operation and monitoring plan, and provide a copy for your review as enclosure 1. The revision addresses impacts to an adjacent pond and includes the new information about dewatering discharges leaving the site. Mine pit operations, are changing with this revision in order to mitigate the unanticipated draw down of a stormwoter-fed pond in the subdivision adjoining the east side of the mine site. Enclosure 1 includes copies of the modified mine plan and revised reclamation plan drawings. When dewatering was'storted in the easti?rnmdst-pit during September of this year, pump h, lr r r discharges were directed into a pond'forrri:ed.ln aminactive portion of the mine immediately to the west, along the south edge of the mine. A.prevlously,filled ditch wds'cledned at that time to restore a connection to the existing ditches on tY e r� ne'siteproperty. Water discharged from the pump into this r.. _. pond travels through the ditches and eventually'ledtie5 the mine site near the southeast corner of the permit boundary. These discharges flow to Upper Broad Creek, approximately 2,800 feet (straight fine distance) to the east of the mine site. A notice of intent for coverage under NPDES NCG020000 is provided as enclosure 2 for your review and information.

HOLTON PIT PORTION, USGS UPPER BROAD CREEK QUADRANGLE NCDENR SITE HYDROGEOLOGY INFORMATION DRAWINGS: Modified Mine Plan & Revised Reclamation Plan for J.C. Holton Pit N.C. Mining Permit 25-14 Located on Broad Creek Road - Holton Property prepared by Robert M. Chiles, P.E. INTRODUCTION This plan contains the pump operation and monitoring procedures for proposed mine dewatering activities associated with the J.C. Holton Sand Pit operated by W.O. Whife, LLC, and located at 1 191 Broad Creek Road, in Craven County, PURPOSE In order to facilitate "dry" mining techniques, permission is being sought to dewoter the active excavation. AQUIFER INFORMATION According to the NCDENR, Division of Water Resources, Visual Hydrogeologic Framework, North Carolina Hydrogeological Database website, one hydrogeoiogic units is present within the proposed maximum depth of the mine site, the Surficial aquifer. The top of the Yorktown confining unit is estimated to be 75 feet below the existing ground elevation, as such, it should not be affected by the proposed dewatering activities. This information is based upon the approximate center of the mine (lot 34.1 194N, long 76.9583W) and data recorded from NDENR boreholes nearest the mine. The NDENR information also reports an estimated ground surface elevation of thirty two feet, and the depths herein reported are corrected to reflect an existing ground elevation of approximately 12 feet. A copy of this information is provided with this plan. During a site visit made in March of 2005, the groundwater surface elevation in the inactive portions of the mine was approximately 3 feet below the existing ground. This inactive potion of the mine had no distinct discharge point and was receiving the discharge from the mine dewatering pump. During a November 15, 2006 onsite meeting with NCDENR, the active portion of the mine was the easfernmost pit where water had been observed during the March 2005 site visit. Water levels in this pit was observed during the November visit at an elevation approximately 25 feet below original grade. Water removed from this portion of the mine was being pumped into a pond formed in an adjacent inactive portion of the mine located to the west. The new receiving pond contains a discreet connection to the existing ditches on the mine site. The ditches flank the entrance road and eventually discharge to the east, toward Upper Broad Creek. PUMP fNFORMATION The current pump is a hydraulically coupled submersible pump with a maximum capacity of approximately 2,000 gallons per minute. The pump engine is positioned on the bank of the active mine pit, hydraulically coupled to a submersible pump in the pit and used to provide a lowered water surface elevation to a maximum depth of 35" feet below existing grade. ("Pending approval of the requested mine permit modification) PUMP OPERATIONS Pumping wi11 be employed as groundwater is encountered, and the pump will be utilized as required to maintain a water surface elevation that is slightly lower than the excavation bottom fo enable the use of "dry" mining fechniques. Continuous use of the proposed pump at its reported capacity will result in 2,900,000 gallons of water removed from the active excavation pit per day. It is recommended that pumping activities be suspended whenever periods of inactivity at the mine will last longer than the time required to dewater the active pit. PUMP DISCHARGE The dewaiering pump discharges into previously excavated, inactive portions of the mine site. One of the water bodies formed by the inactive portions of the mine has a discreet discharge point. A connection to the existing ditches has been cleared to allow wafer pumped into a pond formed in the south central portion of the mine to discharge from the site. Water discharged from the pump into this pond travels through the ditches and eventually leaves the mine site near the southeast corner of the permit boundary. These discharges flow to Upper Broad Creek, approximately 2,800 feet (straight line distance) to the east of the mine site. Water leaving the mine site shall be visually inspected for suspended solids (soil particles). If found, dewaiering pump discharges shall be relocated and/or redirected to eliminate this condition. The mine is located within the_Neuse River Basin, and the nearest surface water is an unnamed tributary of Upper Broad Creek, a tributary of the Neuse River. The headwaters of the tributary are located approximately 1000 feet from the mine. MONITORING PLAN (PUMP) Pump monitoring is required for the Central Coastal Plain Capacity Use Area Water Use Permit. Monitoring shall include type and number of pumps operating, hours operated, volume withdrawn (gallons per day), depth of pump intake (below existing ground), water surface elevation, and any additional information requested by the permitting agency. Monitoring shall be performed daily unless otherwise directed/allowed by the permitting agency. During pumping, withdrawal rates shall be assumed to equal previously indicated pump capacity unless actual measurements indicate otherwise. Withdrawal rates shall be reported according to the requirements dictated by the applicable permitting agency. Pump withdrawal rate records shall be retained for a period of at least 5 years from the date of measurement, unless otherwise indicated by permitting agencies. MONITORING PLAN (WELLS) There are no known wetland areas or private water supply wells in or around the mine site. No monitoring wells are currently proposed. The permeable sands present in the mine apparently extend to and provide a hydrologic connection to a pond in the adjoining subdivision. The pond is located 200-250 feet horizontally from the easternmost portion of the mine. Dewatering of the easternmost mine pit was initiated in September 2006, and as the pit's water level was lowered to approximately 25 feet below existing grade, the water level in the adjoiner's pond fell to a level approximately 4 feet below the "normal" water level that existed in the pond when fhe easternmost it was water -filled. Mine it dewoterin operations are changing with this revision in order to p fa g p g g mitigote the unanticipated draw down of #hat pond, and the water level of the pond will serve as the primary monitoring well for future mine dewatering operations. ' MANDATORY PLAN REVISION In order to mitigate the affect to the adjoining pond, dewatering of the easfernmost pit is ' suspended. A soil dike will be established along the west edge of this pit and the pit will be allowed to fill with water. The top of the dike is approximately 5 to 10 feet below the original ground elevation. Excavation and dewatering will proceed westward from the soil dike, through the rest of ' the mine site. Observations made during a site visit on November 27, 2006 indicate the water level in the easternmost pit had risen approximately 5 feet from the previously lower observations, and the water level in the adjoiner's pond was approximately i foot higher than previously observed. (You may recall a short pier in the northeast portion of the adjoiner's pond. The pier is supported by either three or four pairs of posts. While the easternmost pif was being dewatered, the water surface in the adjoiner's pond appeared to stabilize at a level that put the wafer's edge at the edge of the pair of posts supporting the dock at the end furthest from the shore. During the November 27, 2006, the water level had risen sufficiently to place the water's edge at the next set of posts landward.} The water level in the easternmost pit is expected to rise another 5 to 10 feet to an elevation just below the top of the soil dike. Additionally, the portion of the mine actively dewatered is being relocated westward. The proposed soil dike, water in the easternmost pit, and relocation of the active mining will result in a separation distance of approximately 430 feet between the pond and the nearest extent of the lowered water table. Considering the observations made during the November 27 site visit and the proposed mining modifications, it is anticipated that the water surface in the adjoining pond will rise another 1 to 2 feet higher still, resulting in a water level approximately 1 foot less than was present before pumping was initiated in the easternmost pit. Pump discharges are now being directed into a pond formed in an inactive portion of the mine immediately to the west, along the south edge of the mine. An existing ditch was cleaned to restore a connection to the Existing ditches on the mine site property. Water discharged from the dewatering pump into this pond travels through the ditches and eventually leaves the mine site near the southeast corner of the permit boundary. These discharges flow to Upper Broad Creek, approximately 2,800 feet (straight line distance) to the east of the mine site. A notice of intent for coverage by NPDES General Permit NCG020000 shall be submitted owing to the addition of a discreet (offsite) discharge point to the dewatering system. This plan is subject to further revision as required by the permitting agencies. 1 L, Id r]OIIGW')4 Y. -10 tea" ....... .... . W 4� 'o' "x': `S� 8s, M".

Holton Sand Pit operated by W.O. White, LLC, and located at 1 191 Broad Creek Road, in Craven County, PURPOSE In order to facilitate "dry" mining techniques, water is removed from the active portion of the excavation using a pump(s). AQUIFER INFORMATION According to the NCDENR, Division of Water Resources, Visual Hydrogeologic Framework, North Carolina Hydrogeological Database website, one hydrogeologic unit is present within the proposed maximum depth of the mine site, the Surficial aquifer. The top of the Castie Hayne confining unit is estimated to be 39 feet below the existing ground elevation, two feet deeper than the maximum mine depth. This information is based upon the approximate center of the mine (lat 34.1 194N, long 75.959OW) and data recorded from NDENR boreholes nearest the mine. The NDENR information reports an estimafed ground surface elevation of 10 feet and the confining unit depth reported above is corrected to reflect an existing ground elevation of 12 feet. A copy of the visual hydrogeologic framework information is provided with this plan. PiEZOMETER (MONITORING WELL) iNFORMATiON Purpose Piezometers are used to monifor the extent and effect of proposed mine dewaiering activities on subsurface water levels, and to establish a relationship between the depressed subsurface water levels and any resulting effects on the adjoining properties. No piezometers"(monitoring wells) are currently proposed for the mine dewatering activity.] Adjoining property owners have expressed concern about potential impacts to the water level in their pond caused by mine dewatering activities. To mifigate the effects of dewatering, an existing pump will be replaced by a float controlled pump to maintain the desired water level in the adjoiner's pond using water from the mine pit. There are no known private wafer supply wells in the area of the mine site. Proposed Construction Of -required -by any -of the.permitting agencies, piezometers will be installed in the following manner: Each piezometer shall be constructed using a five foot minimum length of 2" diameter, .010 slotted, PVC screen connected to the length of PVC well casing necessary to extend the tip of the screen to a depth at feast 10 feet below the existing subsurface wafer levels. The piezomeier well casing should extend at leasf one foot above the existing grade. A fine sand pack shall be installed from the bottom of the well to one foot above the top of the screen. A two foot thick bentonite seal shall be placed directly over the sand pack. Native soils removed during well excavation may be used to fill the well to the existing ground elevation. A concrete pad or collar shall be constructed at the existing grade and centered on each well casing to secure the well pipe and provide a stable reference elevation for measuring the groundwater elevation. A removable protective sleeve, cap, or cover shall be installed to prevent direct entry of rainwater and to provide access for measuring the subsurface water level. PUMP INFORMATION The pump used at the mine site is a hydraulically coupled submersible pump with a maximum capacity of approximately 2,000 gallons per minute. The pump engine is positioned on the bank of the active mine pit, is hydraulically coupled to a float mounted, submersible pump located within fhe pit. The pump is used to create a water surface elevation that is a maximum depth of 35 feet below existing grade. PUMP OPERATIONS Pumping will be employed as groundwater is encountered, and the pump will be utilized as required to maintain a water surface elevation that is slightly lower than the excavation activities to enable the use of "dry" mining techniques. Continuous use of the proposed pump(s) of fhe reported capacity will result in 2,900,000 gallons of water removed from the active excavation pit per day. Pumping activities at the mine site have indicated that offer fhe desired water surface elevation is achieved, only 4 to 5 hours of pumping daily are fypicaiiy required to maintain the desired level. A small pump is also being used at the mine site to provide water for maintaining the desired water level in a pond on an adjoiner's property. The pump is being used to mitigate the effects of mine pit dewatering on the adjoining pond. It is recommended that pumping activities be suspended whenever periods of inactivity at the mine will last longer than the time required to dewaier the active pit. PUMP DISCHARGE The dewatering pump currently discharges into a previously excavated, inactive portion of the mine site. The water body formed by the inactive portion of the mine has a single discreet discharge point that is connected to existing ditches along the entrance road. Water discharged from the pump travels through the inactive portion of the mine excavation to the existing ditches and eventually leaves the area of the mine site near the southeast corner of the permit boundary. From this poinf, the existing ditches flow eastward approximately 2,800 feet foword Upper Broad Creek, a tributary of the Neuse River. Upon approval of the December 2008 mining permif modification request, a discharge structure will be installed in the south-east corner of the existing excavation to replace the existing discharge point. Upon initiation of the proposed excavafion, pump discharge will enfer the western portion of the completed existing excavation and discharge through the proposed structure. MONITORING PLAN (PUMP) Pump monitoring is required for the Central Coastal Plain Capacity Use Area Water Use Permit. Pump discharge monitoring is a requiremenf of the NPDES permit. Monitoring shall include type and number of pumps operating, hours operofed, volume withdrawn (gallons per day), depth of pump intake (below existing ground), water surface elevation, and any additional information requested by the permitting agency. Monitoring shall be performed daily unless otherwise directed/allowed by the permitting agency. During pumping, withdrawal rates shall be assumed to equal previously indicated pump capacity unless actual measuremenfs indicate otherwise. Withdrawal rates shall be reported according to the requirements dictated by the applicable permitting agency. Pump withdrawal rate records shall be retained for a period of at {east 5 years from the date of measuremenf, unless otherwise indicated by permitting agencies. MONITORING PLAN (WELLS} No monitoring wells are currently proposed:. The permeable sands present in the mine apparently extend to and provide a hydrogeologic connection to a pond in the adjoining subdivision. The pond is locafed 200-250 feet horizontally from the easternmost portion of the mine and provides a similar function to a monitoring well. If monitoring wells become required? The monitoring wells shall be installed, allowed to stabilize, and existing subsurface water elevations shall be recorded prior to changing the existing dewatering practices. Subsurface water elevations shall be measured relative to a constant datum, such as top of fhe well casing. Subsurface water elevations in the monitoring wells shall be recorded daily Throughout the initial mine water drawdown and until a balance is achieved between water withdrawal activities and groundwater inflow. After a dewatering balance is achieved, subsurface water levels in the monitoring wefts shall continue to be recorded daily until no significant change is recorded. Water levels shall be recorded weekly until no significant change is recorded for two consecutive weeks. Once monitoring well levels achieve this level of stabilify, woier level recording shall continue on a monthly basis. Changes in recording frequency may be subject to permitting agency approval. Permit requirements govern if they conflict with this monitoring schedule. Any time ihaf the dewatering pump depth is increased to create a lower wafer level in the excavation, then piezometer monitoring shall revert to daily monitoring. Monitoring frequency can then be changed according to the plan indicated above. Monitoring results shall be recorded and reported according to the requirements dictated by the applicable permitting agency and shall be retained for a period of at least 5 years from the date of measurement, unless otherwise indicated by permitting agency. CONTINGENCY PLAN In the event that the proposed mine dewatering has an adverse effect on anyother offsite water body adjoining the mine site, action shall be taken to counteract the effect. The action taken shall be agreed upon by the owner of the effected water body, regulatory agency (if applicable), and the mine operator. MANDATORY PLAN REVOON An investigation into the presence of wetlands is being performed near the entrance to the mine site. The results of the investigation, to include a copy of any US Army Corps of Engineers notice of jurisdictional determination and approved delineation, shall be provided when they are completed. The presence of wetlands near the mine site may necessitate revisions to this pion. The approved pump operation plan shall be revised it additional withdrawal capacity is required or if it is determined that there are private water supply wells located in the vicinity of the mine and dewatering activities are adversely affecting their production, or if wetlands are located in the vicinity of the mine. This plan shall also be revised as required by the permitting agencies. ti TO WASHINGTON �4 r B �J � I 2 D E� T +SANDY POffVT Rp „' 1 tti �r 1 TO NEW BERN 4u 'Z 4t NORTI4 VICINITY MAP JC HOLTON PIT W.D.

To provide a buffer area where vehicles can drop their mud and sediment to ovoid transporting it onto public roads, to control erosion from surface runoff, and to help control dust. Wherever traffic will be leaving a construction site and moving directly onto a public road or other paved off -site area. Construction plans should limit traffic to properly constructed entrances. Aggregate Size - Use 2-3 inch washed stone. Dimensions of gravel pad - Thickness: 6 inch minimum Width- 12-ft minimum or full width at all points on the vehicular entrance and exit area, whichever is greater Length: 50-ft minimum Location - Locate construction entrances and exists to limit sediment from leaving the site and to provide for maximum utility by all construction vehicles (Figure 6.06a). Avoid steep grades and entrances at curves in public roads. Washing - If conditions at the site are such that most of the mud and sediment ore not removed by vehicles traveling over the grovel, the tires should be washed. Washing should be done on an area stabilized with crushed stone that drains into a sediment trap or other suitable dispposal area. A wash rack may also be used to moke wash- ing more convenient and effective. 1. Clear the entrance and exit area of all veget- ation, roots, and other objectionable material and property grade it. 2. Place gravel to the specific grade and dimen- sions shown on the plans, and smooth it. 3. Provide drainage to carry water to a sediment trap or other suitable outlet. 4. Use eotexile fabrics because they improve stability of the foundation in locations subject to seepage or high water table. Maintain the gravel pad in a condition to prevent rnud or sediment from leaving the construction site. this may require periodic topdressing with 2-inch stone. After each rainfafl, inspect any structure used to trap sediment and clean it out as necessary. Immediately remove all objection- able materials spilled, washed, or tracked onto public roadways.

PURPOSE To temporarily stabilize denuded,areas that will not be brought to final grade for a period of more that 30 working days. Temporary seeding controls runoff and erosion until permanent vegetation or other erosion con- trol measures can be established. In addition, it provides residue for soil protection and seedbed preparation and reduces problems of mud and dust production from bare soil surfaces during con- struction. CONDITIONS WHERE On any cleared, unvegetated, or sparsely vegetated PRACTICE APPLIES soil surface where vegetative cover is needed for less than 1 year. Applications of this practice include diversions, dams, temporary sediment basins, temporary road banks, and topsoil stock- piles. PLANNING Annual plants, which sprout and grow rapidly and CONSIDERATIONS survive for only one season, are suitable for temporary establishing initial or vegetative cover. Temporary seeding preserves the integrity of earthen sediment control structures suN as dikes, diversions, and the banks of dams and sediment basins. It can also reduce the amount of maintenance associated with these devices. For exampple the frequency of sediment basin cleanouts will be reduced if watershed areas, outside the active construction zone, are stabilized. Proper seedbed preparation, selection of appropri- ate species, and use of quality seed are as imppor- tant in this ppractice as in Practice 6.11, PERMA- NENT SEEDING. Failure to follow established guidelines and recommendations carefully may result in on inadequate or short—lived stand of vegetation that will not control erosion. Temporary seeding provides protection for no more than 1 year, during which time permanent stabili- zation should be initiated. SPECIFICATIONS Complete grading before preparing seedbeds and install all necessary erosion control practices, such as dikes, waterways and basins. Minimize steep slopes because they make seedbed preparation difficult and increase the erosion hazard. If soils become compacted during grading, loosen them to a depth of 6-8 inches using a ripper, harrow, or chisel plow. SEEDBED PREPARATION Good seedbed preparation is essential to success- ful plant establishment. A good seedbed is well - pulverized, loose, and uniform. Where hydroseed- ing methods are used, the surface may be left with a more irregular surface of large clods and stones. LIMING - Apply lime according to soil test recom- mendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone at the rate of 1 to 1 1/2 tons/ccre on coarse -textured soils and 2-3 tons acre on fine - textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed. FERTILIZER - Base application rates on soil tests. When these are not possible, appl a 10-10-10 grade fertilizer at 700-1,000 /b Ycre. Both fertilizer and lime should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more than 30 minutes before application. SURFACE ROUGHENING - If recent tillage operations have resulted in a loose surface, additional roughening mayy not be required except to break up large clods. if rainfall causes the surface to become sealed or crusted, loosen it just prior to seeding by disking, raking, harrowing, or other suitable methods. Groove or furrow slopes steeper that 3:1 on the contour before seeding (Practice 6.03, SURFACE ROUGHENING). PLANS SELEC- fQN elect an appropriate species or species mixture from Table 6.10a, for seeding in late winter and early spring, Table 6.10b for summer, and Table 6.1Oc for fall. SEEDING Evenly apply seed usingad cyclone seeder (broad- cast), drily cultipacker, seeder, or hydroseeder. Use seeding rates given in Tables 6.10a-6.10c. Broadcast seeding and hydroseeding are apppropriate for steep slopes where equipment cannot 3�e driven. Hand broadcasting is not recommended because of the difficulty in achieving a uniform distribu- tion. Small groins should be planted no more than 1 inch deep, and grasses and legumes no more than 1/2 inch. Broadcast seed must be covered by raking or chain dragging, and then lightly firmed with a roller or cultipacker. Hydroseeded mixtures should include a wood fiber (cellulose) mulch. MULCHING The use of appropriate mulch will help ensure establishment under normal conditions and is essential to seeding success under harsh site conditions (Practice 6.14, MULCHING). Harsh site conditions include: seeding in fail for winter cover (wood fiber mulches are not considered adequate for this u se), slopes steeper than 3:1, excessively hot or dry weather, adverse soils (shallow, rocky, or high in clay or sand), and areas receiving concentrated flow. If the area to be mulched is subject to concen- trated waterflow, as in channels, anchor mulch with netting (Practice 6.14, MULCHING). 6.10 TEMPORARY SEEDING continued MAINTENANCE Reseed and mulch areas where seeding emergence is poor, or where erosion occurs, as soon as possi- ble. Do not mow. Protect from traffic as much as possible.

ENGINEER f SURVEYOR OPERATOR 6.11 PERMANENT SEEDING DEFINITION Controlling runoff and erosion on disturbed areas by establishing perennial vegetative cover with seed. PURPOSE To reduce erosion and decrease sediment yield from disturbed areas, and to permanently stabilize such areas in a manner that is economical, adapts to site conditions and allows selection of the most appropriate plant materials. CONDITIONS WHERE Fine -graded areas on which permanent, long-lived PRACTICE APPLIES vegetative cover is the most practical or most effective method of stabilizing the soil. Perma- nent seeding may also be used on rough -graded areas that will not be brought to final grade for a year or more. Areas to be stabilized with permanent vegetation must be seeded or planted within 30 working days or 120 calendar days after final grade is reached, unless temporary stabilization is applied. PLANNING Vegetation controls erosion by protecting bare CONSIDERATIONS soi? surfaces from raindrop impact and by reducing the velocity and volume of overland flow. The most common and economical means of stabiliz- ing disturbed soils is by seeding grasses and legumes. The advantages of seeding over other means of establishing plants include the smaller initial cost, lower labor input, and greater flexibility of method. The disadvantages of seeding include: potential for erosion during the establishment stage, the need to reseed areas that fail to estab- lish, seasonal limitations on suitable seeding dates, and a need for water and appropriate temperatures during germination and early growth. The pprobability, of successful plant establishment can be maximized through good planning, knowledge of the soil characteristics (Table 6.11 a, selec- tion of suitable plant materials for the site, good seedbed preparation, adequate liming and fertilization, and timely planting and mainte- nance. SELECTING PLANT MATERIAL Climate, soils, and topography are the major factors affecting the suitability of plants for a particular site. All three of these factors vary fa el im ysspNorthteYec ilon, a KEY TO PERMANENT SEEDING MIXTURES is presented in Table 6.11b. To find seeding specifications for a specific site, follow this key through the different steps to the appropriate seeding number. Seeding mixtures recommended here are designed for general use and are well proven in practical field situations. They are designed to produce maximum stabilization and minimize the amount of maintenance and repair required. LAND USE is a primarT consideration in planning permanent seedin s. For this purpose land use, whether residential, industrial, commercial, or recreational, can be divided into two general categories: High-maintencneeareas are mowed frequently, limed and fertilized regularly, and either (1) re eive intense use (e.g., athletic fields) or {2 require maintenance to an aesthetic stand- ard (e.g., home lawns). Grasses used for these situations ore long --lived perennials that form a tight sod and are fine -leaved and attractive in appearance. They must be well - adapted to the geographic area where they are planted and able to endure the stress of frequent mowing. Sites where higgh-maintenance vegetative cover is desirable inci�ude homes, industrial parks, schools, churches, and recreational areas. Low -maintenance areas are moved infrequently or not at all, and do not receive lime and fertilizer on a regular basis. Plants must persist with little maintenance over long periods of time. Gross and legume mixtures are favored for these sites becc:use legumes are a source of soil nitrogen. Mixed stands are also more resistant to adverse conditions. Sites suitable for low -maintenance ve etation include steep slopes, stream or channer banks, some commercial properties, and "utility" turf areas such as roadbanks. SEEDBED PREPARATION The soil on a disturbed site must be amended to rovide an optimum environment for seed germina- ion and seedling growth. The surface soil must be loose enough for water infiltration and root penetration. The pH (acidity or alkalinity) of the soil must be such that is not toxic and nutri- ents are available - preferably between 6.0 and 6.5. Sufficient nutrients - added as fertilizer - must be present. It is as important to add lime as to add fertiliz- er. Lime is used primarily as a pH, or acidity, modifier, but is also supplies calcium and magne- sium, which are important plant nutrients. By increasing soil pH it also makes other nutrients more available to plants. At the same time, it prevents aluminum toxicity by decreasing the solu- bility of soil aluminum. Many soils in North Carolina are high in aluminum, which stunts plant growth. After seed is in place, it must be protected with a mulch to hold moisture and modify temperature extremes, while preventing erosion during seeding establishment. STEEP SLOPES The operation of equipment is restricted on slops steeper than 3:1, severely limiting the qualityof the seedbed that can be prepared. The soil cannot be sufficiently worked, and amendments cannot be thoroughly incorporated. Provisions for establishment of vegetation on steep slopes can be made during final grading. In construction of fill slopes, for example the last 4-6 inches might be left uncomppacted. A loose, rough seedbed is essential. Large clods and stones provide irregularities that hold -seeds and fertilizer. Cut slopes should be roughened. Where steepness prohibits the use of form machin- ery seeding methods are limited to broadcast or hycroseeding, with hydroseeding giving the most dependable results. Vegetation chosen for these slopes must not require mowing or other intensive maintenance. Using a hydraulic seeder, seed, fertilizer, wood fiber mulch, and a tacking agent can be applied in one operation. Good mulching practices are critical to protect against erosion on steep slopes. When using saw, anchor with netting or asphalt. On slopes steeper than 2:1, jute, excelsior, or synthetic matting may be required to protect the slope. 6.11 PERMANENT SEEDING continued SPECIFICATIONS SEEDBED REQUIREMENTS Establishment of vegetation should not be attempt- ed on sites that are unsuitable due to inappropri- ate soil texture (Table 6.11a), poor drainage, concentrated overland flow, or steepness of slope until measures have been taken to correct these problems. To maintain a good stand of vegetation, the soil must meet certain minimum requirements as a growth medium. The existing soils should have these criteria: Enough fine -grained (silt and clay) material to maintain adequate moisture and nutrient supply (,available water capacity f at least .05 inches water to 1 inch of solT Sufficient pore space to permit root penetra- tion. Sufficient depth of soil to provide an ade- quate root zone. The depth to rock or im- permeable layers such as hardpans should be 12 inches or more, except on slopes steeper than 2:1 where the addition of soil is not feasi- ble. A favorable pH range for plant growth, usually 6.0-6.5. Freedom from large roots, branches, stones, large clods of earth, or trash of any kind. Clods and stones may be left on slopes steeper than 3:1 if they are to be hydroseeded. If any of the above criteria are not met - i.e., if the existing soil is too coarse, dense, shallow or acidic to foster vegetation - special amend- ments are required. The soil conditioners de- scribed below may be beneficial or, preferably, topsoil may be applied. SOIL CONDITIONERS In order to improve the structure or drainage characteristics of a soil, the following materials may be added. These amendments should only be necessary where soils have limitations that make them poor for plant growth or for fine turf estab- lishment. PEAT - Appropriate types are sphagnum moss peat, hypnum moss peat, reedsedge peat, or peat humus, ail from fresh -water sources. Peat should be shredded and conditioned in storage piles for at least 6 months after excavation. SAND - clean and free of toxic materials. VERMICULITE - horticultural grade and free of toxic substances. ROTTED MANURE - stable or cattle manure not con- taining undue amounts of straw or other bedding materials. THOROUGHLY ROTTED SAWDUST -- free of stones and debris. Add 6 Ib. of nitrogen to each cubic yard. SLUDGE - Treated sewage and industrial sludges are avcilable in various forms; these should be used only inaccordance with local, State, and Federal regulations. SPECIES SELECTION Use the KEY TO PERMANENT SEEDING MIXTURES (Table 6.11 b) to select the most appropriate seeding mixture based on the general site and maintenance factors. SEEDBED PREPARATION Install necessary mechanical erosion and sedimen- tation control practices before seeding, and complete grading according to the approved plan. LIME AND FERTILIZER needs should be determined by soil tests. Soil testing is performed free of charge by the North Carolina Department of Agri- culture soil testing laboratory. Directions, sample cartons, and information sheets are avail- able through county Agricultural Extension offices or from NCDA. Because the NCDA soil testing lab requires 1-6 weeks for sample turn -around, sam- pling must be planned well in advance of final laroding. Testing is also done by commercial boratories. When soil tests are not available, follow rates suggested on the individual specification sheet for seeding mix chosen. Application rates usually fall into the following ranges: Ground agricultural limestone: Light -textured, sandy soils: 1-1 1f2 tons/acre Heavy -textured, clayey soils: 2- tons/acre Fertilizer: Grasses: 800-1200 lb/acre of 10-10-10 (or the equivalent) Grass -legume mixtures: 800-1200 lb/acre of 5- 10-10 (or the equivalent) APPLY LIME AND FERTILIZER evenly and incorporate into the top 4-6 inches of soil by diking or other suitable means. operate machinery on the contour. When using a hyydroseeder, apply lime and fertiliz- er to a rough, [oose surface. Roughen surfaces Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface (slopes less than 3:1). Fill in or level depres- sions that can collect water. Broadcast seed into a freshly loosened seedbed that has not been sealed by rainfall. SEEDING SEEDING DATES given in the seeding mixture speci- fications are designated as the,, or possible Seedings properly carried out within the best dates have a high probability of success. It is also possible to have satisfactory establishment when seeding outside these dates. However as you deviate from them, the probability of failure increases rapidly. Seeding on the last date shown under "possible may reduce chances of success by 30-50%. Always take this into account in schedul- ing Icnd-disturbing activities. USE CERTIFIED SEED for permanent seeding whenever possible. Certified seed is inspected by the North Carolina Crop Improvement Association. It meets published North Carolina Standard and should bear an official "Certified Seed" label. Labeling of non -certified seed is also required by law. Labels contain important information on seed purity, germination, and presence of weeds. Do not acce t seed containing prohibited noxious weed seed. INOCULATE LEGUME SEED with the "Rhizobium" bacte- ria appropriate to the species of legume. APPLY SEED uniformly with a cyclone seeder, drop - type spreader, drill, cultipacker seeder, or hydroseeder on a firm, friable seedbed. When using a drill or cultipacker seeder, plant small grains no more than 1 inch deep, grasses and legumes no more than 1/2 inch. Equipment should be calibrated in the field for the desired seeding rate. When using broadcast --seeding methods, subdivide the area into workable sections and determine the amount of seed needed for each section. Apply one-half the seed while moving back and forth across the area, making a uniform pattern; then apply the second half in the some way, but moving at right angles to the first pass. MULCH all plantings immediately after seeding. 6.11 PERMANENT SEEDING continued HYDROSEEDING Surface roughening is particularly important when hydroseeding, as a roughened slop will provide some natural coverage for lime, fertilizer, and seed. The surface should not be compacted or smooth. Fine seedbed preparation is not necessary for hydroseeding operations; large clods, stones, and irregularities provide cavities in which seeds can lodge. Rate of wood fiber (cellulose) application should be at least 2,000 lb/acre. Apply legume inoculants at four times the recom- mended rate when adding inoculant to a hydroseeder slurry. If machinery breakdown of 1/2 to 2 hours occurs, add 50% more seed to the tank, based on the proportion of the slurry remaining. This should compensate for damage to seed. Beyond 2 hours, a full rate of new seed may be necessary. Lime is not normally applied with a hydraulic seeder because it is abrasive. It can be blown onto steep slopes in dry form. SPRIGGING Hybrid Bermudagrass cannot be grown fro seed and must be planted vegetatively. Vegetative methods of establishing common and hybrid Bermudagrass, centipedegrass, and Bahiagrass include sodding, pluggin and sprigging. Springs are fragments of hhorizon a' stems whtch include at least one node (joint). They are normoll sold by the bushel and can either be broadcast or planted in furrows using a tractor -drawn tobacco or vegetable trans- p€an{er. FURROWS should be 4-6 inches deep and 2 ft apart. Place springs about 2 ft apart in the row with one end at or above ground level. BROADCAST springs at the specified rate. Press into the top 1/2-2 inches of soil with a culti- acker or with a disk set nearly straight so that he sprigs are not brought back to the surface. IRRIGATION Moisture is essential for seed germination and seedling establishment. Supplemental irrigation can be very helpful in assuring adequate stands in dry .seasons or to speed development of full cover. It is a requirement for fine turf establishment and should be used elsewhere when feasible. However, irrigation is rarely critical for low - maintenance vegetation planted at the appropriate time of the year. Water application rates must be carefully con- trolled to prevent runoff. Inadequate or exces- sive amounts of water can be more harmful than no supplemental water. MAINTENANCE Generally, a stand of vegetation cannot be deter- mined to be fully established until soil cover has been maintained for one full year from planting. Inspect seeded areas for failure and make neces- sary repairs and reseedings within the same sea- son, if possible. RESEEDING - If a stand has inadequate cover, re- evaluate choice of plant materials and quantities of lime and fertilizer. Re-establish the stand after seedbed preparation or over -seed the stand. Consider seeding temporary, annual species if the time of year is not appropriate for permanent seeding. If vegetation falls to grow, soil must be tested to determine if acidity or nutrient imbalances is responsible. FERTILIZATION - On the typical disturbed site, full estcblishment usually requires refertiliza- tion in the second growing season. Fine turf requires annual maintenance fertilization. Use soil tests if possible or follow the guidelines given for the specific seeding mixture.

SOiL AMENDMENTS Apply lime and fertilizer according to soil tests, or apply 300ib/acre 10-10-10. SPRIGGING Plant sprigs infurrows with a tractor -drawn trcns-- planter, or broadcast by hand. FURROWS should be 4-6 inches deep and 2 ft apart. Place sprigs about 2 ft apart in the row with one end at or above ground level. BROADCAST at rates shown above, and press sprigs into the top 1/2-2 inches of soil with a disk set straight so that sprigs are not brought back toward the surface. MULCH Do not mulch. MAINTENANCE Fertilize very sparingly -20 lb/acre nitrogen in spring with no phosphorus. Centipedegrass cannot tolerate nigh pH or excess fertilizer. 6.06 ❑EFINMON A graveled areo or pad located at points where vehicles enter and leave o construction site. PURPOSE To provide o buffer area where vehicles can drop their mud and sediment to avoid transportin if onto public roads to control erosion from surface to help runoff, and control dust. CONDITIONS WHERE Wherever traffic will be leaving a construction PRACTICE APPLIES site and moving directly onto a public road or other paved off —site area. Construction plans should limit traffic to properly constructed entrances. DESIGN CRITERIA Aggregate Size — Use 2-3 inch washed stone. Dimensions of gravel pad — Thickness: 6 inch minimum Width: 12—ft minimum or full width at all points on the vehicular entrance and exit area, whichever is greater Length: 50—ft minimum Location — Locate construction entrances and exists to limit sediment from leaving the site and to provide for maximum utility by all construction vehicles (Figure 6.06a). Avoid steep grades and entrances at curves in public roads. Washing — If conditions at the site are such that most of the mud and sediment are not removed by vehicles traveling over the gravel, the tires should be washed. Washing should be done on an area stabilized with crushed stone that drains into a sediment trap or other suitable disposal area. A wash rack may also be used to make wash- ing more convenient and effective. CONSTRUCTION 1. Clear the entrance and exit area of ail veget— SPECIFiCATIONS ation, roots, and other objectionable material and properly grade it. 2. Place gravel to the specific grade and dimen— sions shown on the plans, and smooth it. 3. Provide drainage to carry water to a sediment trap or other suitable outlet. 4. Use geotexile fabrics because they improve stability of the foundation in locations subject to seepage or high water table. MAINTENANCE Maintain the gravel pad in o condition to prevent mud or sediment from leaving the construction site. this may require periodic topdressing with 2—inch stone. After each rainfall, inspect any structure used to trap sediment and clean it out as necessary. Immediately remove all objection— able materials spilled, washed, or tracked onto public roadways.
