Hanson Aggregates SE is requesting a rcnewal or their permit for mining meta granite on a 437-acre site located near Falls Reservoir. The Meuse .River drains and borders the site. The Ncusc River supports spawning runs of blueback herring (A.losa aestivalis), hickory shad (Alosa mediocris), alewife (.41osa pseudohar•engus), American shad (Alosa sapidissima), and striped bass (Mor-one swcatih's) downstream of the project site and is considered an important recreational fishery; therefore, protecting water quality is essential. In addition, the state special concern four -'toed salamander (I-fenridacrl-liuni scuiatum) is known from the area, and there are historical records for the state special concern Neuse River waterdog (Necturus lewisi). The applicant has indicated that a minimum 50 foot undisturbed buffer will be mahitained for watercourses and wetlands. We recommend that the following conditions be incorporated into the permit to reduce impacts to fish and wildlife resources. In order to reduce stream impacts, while retaining some measuve of wildlife habitat, we recommend a minimurn 100-foot undisturbed, native, forested buffer along perennial streams, and a 50-foot buffer along intermittent streams and wetlands for the present operation and any future expansions.

We request that sediment and control measures be located outside of these buffers. 2. Water discharges from the project site should be proportional to the size of the receiving stream so that the Hydrology of the stream is not altered, andall discharges should comply with 1\TPDES permit requirements. In particular, turbidity of the discharge should be maintained at or below the permit requirement. High water discharge rates and turbidity can negatively impact aquatic and f sherics resources within and downstream of the project area, Excessive silt and sediment loads can have numerous detrimental effects on. aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. I We encourage the applicant to consider using seed mixtures that are beneficial to wildlife in their reclamation plan, such as native, warm season grasses. ,An exact seeding mixture would need to take into account soil types, moisture, pH, and degree of slope of areas to be stabilized. In addition, for relatively shallow sediment basin reclamation, we recommend these areas be reclaimed as wetlands where practicable. We refer the applicant to William Edwards, District Wildlife Biologist, at (252) 459-7891 for additional information and ideas on reclamation for wildlife. Thank you for the opportunity to review and comment on this renewal.

Necessary erosion and sedimentation control structures, visual buffers, etc. are generally to place to support this minor development. As the pit is expanded horizontally, the disturbed areas are graded so that they drain back into the pit as much as practicable. in areas where this will not be possible or desired, proposed erosion and sedimentation control devices as indicated on the permit drawings will be installed as development progresses to control any offsite sedimentation. 2. Describe specific erosion control measures to be installed prior to land disturbing activities and during mining to prevent offsite sedimentation (include spec fic plans for sediment and erosion control for mine excavation(s), waste piles, access/mine roads and process areas), and give a detailed sequence of installation and schedule for maintenance of the measures. Locate and label all sediment and erosion control measures on the mine map(s) and provide typical cross-sections/construction details of each measure. Engineering designs and calculations shall be required when needed to justify the adequacy of any proposed measures. See attached drawings for locations of existing measures and previously approved plans and supporting calculations for specific details. This information has not changed since last previous submittal. Currently a new pit dewatering settling pond and two stormwater ponds are being constructed on the west side of the affected area. The stormwater ponds will accept runoff from the plant, shop, existing and future overburden/waste disposal areas, and existing and future product stockpilareas for treatment prior to discharge through the NPDES outfall associated with the final existing stormwater pond. These ponds were previously permitted in a different configuration and the effort here is to basically provide for as -built conditions. See attached drawings and design notes for specific details. Overburden/waste disposal areas not previously fully delineated are also delineated in this renewal application, along with specific erosion and sedimentation control measures. 3. a. Will the operation involve washing the material mined, recycling process water, or other waste water handling? Yes X No . If yes, briefly describe all such processes including any chemicals to be used. The crushed stone production process requires water for washing the sized stone products at the wash screen to remove dust and fines for their eventual use in asphalt and ready -mix concrete. The water is recycled through a closed-circuit process water settlint pond system.

A pump is also maurtained in the Neuse River for purposes of replenishment of the system during exceptionally dry times. Water is also used for dust control at the facility. Water is used at the processing plant by introduction through sprays at crushers and at conveyor transfer points to control dust emissions. It is also used in the water truck to control dust emanating from haul roads, stockpiles, and the shot rock pile in the quarry. Water used in dust suppression is usually pulled either from the quarry dewatering or from the secondary settling/fresh water pond. At the present time: no chemicals are used in any of these processes; however, we ma apply to Water Quality for permission to used chemical flocculants in the recycle system to help in achieving a cleaner source of water for the plant washing and .dust control. We may also apply for permission to use chemicals such as calcium chloride or organic surfactants on the haul roads and crusting agents on the product stockpiles. b.

We currently have an NPDES Permit (#NCG020209) that covers the discharge of excess ground water from the quarry dewatering process, as well as any excess water from our closed circuit settling pond system. The discharge water is treated by simple sedimentation in a separate settling pond ((currently being reconstructed) and then flows to another existing small pond prior to being discharged through a riser and through pipe to the Neuse River. These ponds and the discharge point are shown on the attached plans. The NPDES permit also allows for the discharge of storm water from the nine site through multiple paint source discharge points.

The overburden materials in the pit area are silts, clays, and sand which inhibit groundwater migration. The 100,000 gpd reported above includes water accumulating by rain falling directly into the quarry as well as stormwater runoff from areas contiguous to the open pit. If you answered yes to any of the above questions, provide evidence that you have applied for or obtained the appropriate water quality permit(s) (i.e., non -discharge, NPDES, Stormwater, etc.) from the Division of Water Qu ity, ater Quality Section. In addition, the applicant is required to register water use with the Division of Water Resources ifthe operation withdraws more than 100,000 gallons per day And needs a capacity use permit from the Division of Water Resources if the operation lies in a capacity use area and withdraws more than 100,000 gallons per day. The Raleigh Quarry operates under NPDES Permit NCG020209 as issued byNCDENR-Water Quality and as outlined above. a. Will the operation involve crushing or any other air contaminant emissions? Yes X No If yes, indicate evidence that you have applied for or obtained an air quality permit issued by the Division of Air Quality or local governing body. The Raleigh Quarry operates under Air Quality Permit # 4151 as issued by NCDENR Division of Aix Quality and is in full compliance with the requirements thereof. A complete system of water sprays is in place at all crushers and conveyor transfer points to controlparticulate emissions from these sources. b. How will dust from stockpiles, haul roads, etc., be controlled? As stated in 3(a) above, a water truck is used to apply water to haul roads, muck pile, and stockpiles as needed to control fugitive emissions from these sources. 5. a.

Minimum 2 horizontal to 1 vertical slopes or flatter for clayey material and minimum 3 horizontal to 1 vertical slopes or flatter for sandy material are generally required, unless technical justification can be provided to allow steeper slopes, In order to prevent landslides and/or slope failure adjacent to adjoining properties, cut slopes will be graded to no steeper than 1 I/2:1 and fill slopes will be graded to no steeper than 2:1. Proper compaction procedures shall be used on fill slopes. All slopes will be stabilized by seeding as soon as possible after grading has been completed. Necessary erosion controls will be used to prevent slope failure by concentrated storm water runoff.

Vegetated earthen berms, appropriate fencing and adequate boulder barriers may be acceptable high wall barricades. A construction detail/cross-section and location of each type of barricade to be used must be indicated on the mine map(s). Access to the property itself is restricted by gates and cables that are kept locked when the quarry is not in operation. Much of the perimeter is fenced. Berms and overburden disposal areas also block access to much of the site and inactive highwalls. During the life of the quarry, barricades of either oversized rock or concrete are used adjacent to active highwalls and are relocated as the pit is developed. -10- s • Are acid producing minerals or soils present? Yes No X How will acid water pollution from the excavation, stockpiles and waste areas be controlled? 10, a. Describe specific plans (including a schedule of implementation) for screening the operation from public view such as maintaining or planting trees, bushes or other vegetation, building berms or other measures. Show the location of all visual screening on the mine maps) and provide cross - sections through all proposed berms or proposed spacing, sizes and species for tree plantings. The Raleigh Quarry presently has a combination of well -developed visual barrier berms as well as natural vegetation which screens this site well from adjoining roads and properties. This screening will be maintained. b. Could the operation have a significantly adverse effect on the purposes of a publicly owned park, forest or recreation area? If so, how will such effects (i.e., noise, visibility, etc.) be mitigated? 1'V o - uUmay owned pant, forest, or recreation area adj Dins the ruuet$h Quarry. i ne site is weii- screened from the Neuse River and the quarry has little or no impact on this significant watercourse. 11. Will explosives be used? Yes __ _ X__ No . If yes, specify the types ofexplosive(s) and describe what precaution(s) will be used to prevent physical hazard to persons or neighboring property from flying rocks or excessive air blasts or ground vibrations, Depending on the mine's location to nearby structures, more detailed technical information ma be required on the blasting progam (such as a third-Partyblasting study). Locate the nearest oyite occupied structures) to the proposed excavation(s) on the mine map and indicate its approximate distance to the proposed excavation. Ensign Bickford or comparable nonel blast initiation system is used to prevent inadvertent blast initiation especially during possible thunderstorms. An electronic initiation system may be substituted for the novel system if it is deemed a better overall system. Weather conditions are monitored continuously before, durin#, and after loading of each shot to insure that the shot will not be initiated under adverse weather conditions that might cause blast emissions to drift in an unacceptable direction or might prevent proper venting of the blast wave away from adjoining properties. ANFO premixed powder is used in dry holes. A cap -sensitive high explosive emulsion is used for wet holes and initiation of the ANFO. Since blastin8 is an intejgral part of this operation, each blast is monitored with a seismograph to insure that peak particle velocities and peak overpressures are within limits established by local, state, and fi_riataa aiithnritiPc i-Xart-nn tunrlr�arin�iv vcrith n„nng�wltant� (1„s,�911y Viirr�ferh) to rnnmtnr �nr� rn'nMnv each blast and the seismograph recording,. �ilon with the seismograph results, fragmentation and fly rock conditions are constantly monitored and the blasting program, including direction of blasting, hole sue and pattern, stemming, etc. are adjusted as needed to insure best and safest results. lmw� MMMMI L; COON: up% "M 0LYQvQw ff Wn qQ :0), tZicya, qqq BUY 1:0! 1 (,'.1 pl.

RECLAMATION PLAN Describe your intended plan for the final reclamation and subsequent use of all affected lands and indicate the sequence and general methods to be used in reclaiming this land. This must include the method of reclamation of settling ponds and/or sediment control basins and the method of restoration or establishment of any permanent dr ' gge channels to a condition minimizing erosion, siltation and other pollution. This information must beeiillustrated on a reclamation map and must correspond directly with The information provided on the mine map(s). In addition, design information, including typical crass -sections, of any permanent chanmels to be constructed as part of the reclamation plan and the locations) of all permanent channels must be indicated on the reclamation map. The mine excavation will be allowed to fill by ground water and storm water runoff from adjoining areas once the mining operation is completed. The resulting deep -water lake will be used for recreation, and potentially as a fresh water supply for local utilities. The plant site, stockpile areas, and overburden disposal areas will be waded and seeded with grasses suitable for establishment of grasslands and wildlife areas. Process and pit water settling ponds and sediment basins will be filled and similarly reclaimed to grasslands unless they are part of the overall final site drainage and reclamation plan. See attached drawings for specific details. 2. Is an excavated or impounded body of water to be left as a part of the reclamation? Yes . -_ 2j_ No if yes, illustrate the location of the body(s of water on the reclamation map and provide a scaled cross -sections) through the proposed holy(s) of water. The minimum water depth must beat least 4 feet, measured from the normal low water table elevation, unless information is provided to indicate that a more shallow water body will be productive and beneficial at this site. Will the body(s) of water be stocked with fish? Yes No X . If yes, specify species, It is Hanson's intent to convert the quarry into a fresh water take upon cessation of mining activities. In addition, stormwater ponds 1 and 2 as shown on the attached drawings will remain. See attached drawings for specific details and cross -sections. Describe provisions for safety to persons and to adjoining property in all completed excavations in rock including what kind of permanent buricade will be left. Acceptable permanent barricades are appropriate fencing, large boulders placed end -to -end, a#c. Construction details and locations of all permanent barricades must be shown on the reclamation map. As a safety precaution, a 20-foot wide safety bench will be left at the rock/unconsolidated soil interface.

Erosion control measures and runoff conveyances will be established as the waste area develops and then maintained throughout the process until final reclamation is achieved. Drainage on top of waste areas will be established to prevent pooling and stagnation of water and to control stormwater runoff. Final reclamation of waste areas will include final top and slope dressing as required followed by seeding in accordance with the revegetation plan included herein. See attached drawings for specific details. 5. a. Describe reclamation of processing facilities, stockpile areas, and on -site roadways. Reclamation in these areas will occur as follows. First, the product stockpiles will be sold down. Then the processin plant will be dismantled and removed from the site. Any remaining piles, waste piles, and areas graded for plarn layout and operation will be graded to 2:1 maximum slope (generally 3:1 or flatter). Finally these areas will be scarified and seeded according to the revegetation plan. Any site access roads not utzed in the end use development plan will be treated in the same manner. Any erosion control structures in these areas to be incorporated into the end use development of the site will be cleaned out and left in good working condition. b. Will any on -site roadways be left as part of the reclamation? Yes X� No . Ifyes, identify such roadways on the reclamation map and provide details on permanent ditch line stabilization. Main paved roads into existing stone processing plant area and asphalt plant area will remain for access and future development purposes. Road from upper plant level down to lower basin level behind shop will remain and will be graded (including side drainage ditches) and stabilized with rock. Describe the method of control of contaminants and disposal of scrap metal, junk machinery, cables, or other such waste products of mining. (Note definition of refuse in The Mining Act of 1971).

Easley, Governor William G. Ross Jr., Secretary Our office has completed its review of Hanson Aggregates' blasting information, including blast reports and seismograph recordings, related to the blast conducted at its Raleigh Quarry during the period of February 11, 2005 through February 24, 2005. It was found that Hanson Aggregates was in compliance with the blasting requirements of its mining permit during the period in question. All peak particle velocities, a measurement of ground vibration with units in inches per second (ips), were well below the maximum allowable limits specified in Hanson Aggregates' mining permit. More specifically, all recorded values were at or below 0.058 ips. All airblast readings, a measurement of the atmospheric pressure wave (overpressure) with units in psi or dBL, were also below the maximum allowable limits specified in the mining permit and well below the U. S. Bureau of Mines' recognized level of 164 dBL for prevention of glass breakage. A key point worth noting is that glass breakage occurs at much lower levels of overpressure than structural damage, such as cracking plaster. Thank you for your interest and patience in this matter. Hopefully I have answered your concerns adequately. If you should have any additional questions or concerns, please contact me at (919) 733-4574.

Box 848 Cheraw, South Carolina 29520 Tel 843 537 7883 Fax 843 537 4871 This is in answer to your request by letter dated May 15, 2001 for additional information regarding our above -referenced application for permit modification. Enclosed are two sets each of the revised design notes and the Mine Plan and Reclamation Plan drawings. Referring to Mr. John Holley's e-mail that was attached to your letter, please note the following in answer to his concerns: 2(a) - We have eliminated the temporary rock check dam from the E&S plan. By changing the sequence of the work activities and E&S control measure installation, we feel that we can have only a minimum of land disturbed for a minimum time that would impact the area below the proposed +25-yr. storm outfall. As indicated on the revised work sequence found both in the design notes and on the Mine Plan drawing, we will begin by disturbing only the area required to install the 15" RCP under the project area and the area required to proceed with installation of the head -killer basin. We will use temporary silt fencing below this small area to treat runoff during the two weeks it will take to complete this phase of the work. Any stormwater from above the project site during this period will be held and/or routed around the site as indicated. See Section VI of the design notes for a more complete description. 2(b) - Slope drain configuration has been changed somewhat and individual drains have been sized in accordance with allowable standards in the NC E&S Manual. Culvert sizing has been checked and inlet control conditions, as well as exit conditions and total head loss, taken into account. See revised Sections II and V-C of the design notes. According to our calculations, the 15" RCP culvert and the 8" steel discharge nine {arcs i►nih �rin."I I�inl{�i�rnrl r/IrJV ■�VIV {/V{II iRV VMI.{GI{V I� VILVV• 2(c) - Please see the revised section II of the design notes (Pages 2-3) for a more completion description of the retention basin draw -down process. The water level in the ponds will be continually monitored and pulled down as needed in order to insure that the ponds will hold the 25-yr. storm when it occurs. 2(d) - The head on the retention basin drain pipe valve as originally located in our design will be only 2 psi maximum. This will cause no problem in operation of the valve. We had placed the valve on the discharge end of the pipe for ease of access, installation, and maintenance, along with corresponding safety concerns, and wish to leave it there. In consideration of the above items, it is our understanding that we are only required to design for the 10-yr storm event. We have actually designed for the 25-yr., and in some cases, the 50-yr. event and thus feel that we have gone beyond the norm in our efforts to protect adjacent resources. We trust that all of the information supplied to you is now sufficient to allow your department to complete the processing of our application; however, should you require any additional information, do not hesitate to contact the writer.

Erosion and Sediment Control Planning and Design Manual Using TR-55 for calculation of Maximum Expected Runoff from 50-yr. Storm Event. Runoff to the Neuse river will be controlled as follows: Two retention ponds will be constructed along the lower toe of the disturbed area. Joined by a ditch, they will be sized so as to in combination contain the 25-yr. storm runoff. A piped connection to the plant s settling basin system fresh water return pond will be used to release the accumulated 25-yr.runoff for use at the plant. Runoff from up to a 50-yr. storm will be treated by settling in the retention pond and then discharged via suitably sized outfall structure.

Our plan is to bleed this water off as it accumulates for use as make-up water in our closed -loop plant wash water settling basin system. We will install a drain pipe from the retention pond system with a gate valve for controlling the water flow into the closed -loop system. ji I 01 0 P ;-J t, 4 t3% 2! i tZ. �-!Xl ;J g 0 • • Pg. 3of§ We normally circulate approximately 2,000 GPM of water to the plant to be used in the stone washing process. Approximately 10% of this useage is lost on a continual basis by absorption into the washed stone products and evaporation. In addition, we normally use 200 GPM for plant wash down and in the water truck for area -wide dust control. All of this water is lost from the system daily. We normally make up for this water loss in the closed loop system by adding in water pumped from the quarry dewatering operation and from a river pump. Upon installation of the E&S controls covered by this mine permit modification, we will use this runoff water as a primary source of make-up water for the closed -loop system. Plant personnel will be trained in the operation for the system and will responsible on a daily, or otherwise short-term basis, for maintaining the water level in the retention ponds at the 218.5' elevation. Setting inlet invert of drain pipe at elevation = +/-218.5, assuming we have held the 25- yr. storm event, we will have a total of 152,000 d of stored water. Planning to drain this accumulated water off in 6 days at 10 hrs/day = 60 hrs., we need to drain 152,000 d / 60 hrs = 2533 d/hr = 0.70 cfs (or 314 GPM). This will be the primary make-up water supply for the closed -loop pond system (requirements as outlined above) during this period.

(a) The proposed Rock Check Dam must be designed/constructed in accordance with the manual specifications. Particular attention needs to be given to stone and spillway design. (b) The design of culverts and slope drains does not consider inlet control conditions that will significantly impact the available capacity. Roth appear to need to be increased in size. Dissipator designs are also neededffor slope drains. (c) Although the total available storage in the proposed pond looks OK, the intended operation of the pond is not clear. If the EMS were to control the water level prior to a storm event, the available storage may not be sufficient to contain the 25yr. runoff as proposed. This should be clarified and documented better. (d) Although the dike serving the pond is small and the head will be low, the drain valve should be installed on the upstream end of the conduit. I would not recommend approval until the deficiencies listed above are addressed. Thanks for your patience.

Our comments are provided in accordance with provisions of the Mining Act of 1971 (as amended, 1982)(G.S. 74-76 through 74-68 15 NCAC 5), Hanson Aggregates Carolina, Inc, is requesting a modification to add eight acres of affected acreage to their granite -mining permit. The proposed modification involves the removal of approximately 100,000 cubic yards of material to be used on a nearby highway project. A level bench cut into the side of the hill will result from the removal, and the site will then be used as a disposal area for settled sludge. The Neuse River drains the site. We concur with the project modification provided that the ininimum 100-foot undisturbed, forested buffer along all streams, watercourses, and wetlands are maintained. This 100-foot buffer will protect water quality and provide an adequate travel corridor for wildlife species. In addition, water discharges from the Ni-jt;it sii(; shUtdid Irm l)ropo1-iiona11to the size of the receiving stream, and all discharges should comply with NPDES permit requirements. In particular, turbidity of the discharge should be maintained at or below the permit requirenne,nt. High water discharge rates and turbidity can negatively impacl aquatic and fisheries resources within and downstream of the projccl area.

Erosion and Sediment Control Planning and Design Manual Using TR-55 for calculation of Maximum Expected Runoff from 50-yr. Storm Event. Runoff to the Neuse river will be controlled as follows: Two retention ponds will be constructed along the lower toe of the disturbed area. Joined by a ditch, they will be sized so as to in combination contain the 25-yr. storm runoff. A piped connection to the plant's settling basin system fresh water return pond will be used to release the accumulated 25-yr.runoff for use at the plant. Runoff from up to a 50-yr. storm will be treated by settling in the retention pond and then discharged via suitably sized outfall structure. 1. Calculate 25-yr. storm peak runoff, determine runoff retention times/volumes and sediment storage required in ponds. Maximum runoff will occur after timber has been harvested and borrow excavation begins, culminating in bare, leveled site. A. — Base Information for Peak Runoff Calculation Location: Raleigh, N. C.

The operations required in this modification includes the following: Mining operations within the existing pit are to proceed in such a manner to develop all working surfaces required for the installation of primary crusher station and associated equipment inside the existing pit. This includes the development of pit access roads, working surfaces and shear walls to the required horizontal and vertical plains. Normal stripping operations are to continue with the placement and compaction of materials in the new plant area. This operation will continue until this area is developed to subgrade elevation. Erection of the new plant proceeds with the construction / erection of equipment, crushers, conveyors etc. as both "pit' & "plant" areas are developed to the required subgrade conditions. Construction of new plant equipment consist of the placement of new machinery and the installation of modified existing equipment. As the entrance areas are developed to subgrade elevations, normal stripping operations are to continue with material being used to create visual barrier berms.

Normal stripping and mining operations will continue toward the west as in manner to advance the existing pit towards the new mining limits line. As slopes are stabilized development of detention ponds will commence. Normal dipping and grading operations will develop the 4 cells required detention pond # 1. Normal dipping and grading operations will develop existing detention pond #2. As soon as detention ponds and adjacent areas are graded to required elevations and stabilized, stripping and grading operations shall begin for the installation of channel "D" and new 72" CMP pipe with required inlet/outlet protection. Operations and procedures will be conducted in sequential order as listed or concurrent as to meet the market demands.

Given below are several possible causes that may explain the unusual results from the July 23, 1997, blast. Any one of the items may have contributed. They are listed by probability of cause. 1 An eighteen foot (18') front line burden may be too excessive and prevent face departure.

Your investigation' report contained information regarding the high air blast recording associated with -- the blast conducted at the quarry on July 23, 1997. An overpressure measurement of 129 dBl was measured by your company's seismograph at approximately 1600 feet from the blast. This office has completed its review of your investigation report. It appears that the excessive airblast reading for this shot was related to cracks in the face of the shot. Venting of explosive gases caused by borehole #25 opening a fracture in the face of the shot likely generated the high airblast reading. It appears that your blasting company took all the necessary precautions to address the backbreak problem along the face of the shot. The thorough analysis of the face and drill --logs along with the design and loading of the shot should have reduced the potential for high airblast. Unfortunately, a seam joint opened during the blast, which could not be detected or prevented during the design of the shot. As all necessary precautions were taken and this backbreak area has now been eliminated, no additional measures are recommended at this time. However, please incorporate the same precautions used during this blast on all future shots at this site. If future airblast readings continue to exceed 128 dBl at this site, modifications to the blasting conditions currently outlined in Mining Permit No. 92--02 may be made by the Department.

Also present at the site was Scott Hartness who is a Mine Safety and Health Representative from the NC Dept. of Labor. Also enclosed is a statement prepared by him, Along with those statements is the shot report with the seismograph information on it. I am sending the disk with the seismic information to Vibra- Tech and will forward a copy of their report to you when it is received. Blastrite Service has just started servicing our company at this quarry. This was their second shot at this site, They are having to deal with some badly cracked faces which were a result of a severe back break from the previous explosive company. We feel that the problem area has been eliminated and will do everything possible to keep this from happening in the future. We feel that it is very important to comply with all regulations and safe guards which govern our industry. More so we are concerned about being good neighbor and the safety of our neighbors.

Box 13983 Research Triangle Park, North Carolina 27709•-3983 RE: Excessive Airblast Incident of November 4, 1996 Raleigh Quarry Mining Permit No. 92.-02 Wake County Dear Mr. Lineberry: This letter is in reponse to your November 13, 1996 letter to Mr. Tracy Davis of.the Land Quality Section regarding the above referenced.incident. Your letter included copies of investigations of the incident performed by ES Quarry & Construction Services and Vibra-Tech. An overpressure measurement of 129 dbl was measured by your company's seismograph located at Jeffries Furniture around 9:21 am on November 4, 1996. --This office has completed its review of the investigation reports and agrees that the excessive arblast- reading for this shot was related to the items outlined in both -reports. The most probable cause was internal geologic conditions, such as fracturing and voids, that contributed to gases venting directly through the first row face. Atmospheric conditions, such as temperature inversions, may have also contributed to the incident. I concur with the remediation measures outlined in the attachments to your November 13th letter. Primarily, the remediation measures are as follows: 1) Closer communication between the driller and explosives personnel shall be conducted. Voids and fracturing are quite discernible during the drilling process and this information must be required by and shared with the explosives personnel.

Blasting during temperature inversions should be avoided whenever possible. 3) A qualified blasting consultant shall closely monitor your company's entire drilling and blasting program at this site for a period of 30 days from the date of this letter. This should determine if any other changes in the drilling and blasting program are needed to prevent future incidents from occurring., In order to reduce excessive airblast readings in the future at this facility, the above remedial measures proposed by your company will be considered part of the blasting procedures outlined in Mining Permit No. 92-02. Please attach a copy of this letter to your mining permit for this site for future reference.

Your letter included copies of investigations of the incident performed by ES Quarry & Construction Services and Vibra-Tech. An overpressure measurement Of 129 dbl was measured by your company's seismograph located at Jeffries Furniture around 9:21 am on November 4, 1996. This office has completed its review of the investigation reports and agrees that the excessive airblast reading for this shot was related to the items outlined in both reports. The most probable cause was internal geologic conditions, such as fracturing and voids, that contributed to gases venting directly through the first row face. Atmospheric conditions, such as temperature inversions, may have also contributed to the incident. I concur with the remediation measures outlined in the attachments to your November 13th letter. Primarily, the remediation measures are as follows: 1) Closer communication between the driller and explosives personnel shall be conducted. voids and fracturing are rmi t-rm r1i enarnihl a r1>>ri nrr i-ha riri 1 1 i nrr nrnr+acc anri thi a .�.,._..... .�_ ....____-....... ,r,..__--� �--.. .ram.-___--� r-.................. ....,.. ....�.. information must be required by and shared with the explosives personnel.

RALEIGH QUARRY Dear Sirs, 1 On � 4, 1996 we detonated a blast at the Benchmark Carolina Aggregates North Raleigh Quarry which resulted in an airblast reading exceeding the state allowable limit of 128db. Details as follows: The blast was loaded, as planned and in the usual manner. Care was taken to inspect the face and observe any irregularities. There was an undercut on the face, and some surface cracks visible on the horizontal surface. During bulk loading, the explosive column was continousiy checked to account for all product. 1 noticed immediately on the first hole loaded that there was a void or crack that the product was seeping into. Loading stopped. Two 4" sticks of Power -An 7000 were loaded into the hole, and it was backfilled with #78m. Later, a second hole responded similarly and loading ceased. Two 4" Power -An 7000 sticks were loaded into the hole, and it was Backfilled. It required many times the expected amount of stone to completely fill the hole, even after "choking it off " to seal the void. I estimate less than 30 lbs of explosives was lost into the void. The balance of the shot loaded without any problems. The shot was tied in, double checked and the area cleared. I notified the pit foreman about the voids, and to be prepared in case of venting ( a standard precaution ) . The horn was sounded, and the shot fired. The shot did vent. The area was checked, and pronounced " all clear ". A scismograpii set up at Jelfuies iFul-1 itura registered 129db and 0.1 lips ppv (2200' distant ). There were no complaints at the time of the blast, Although the owner of Jeffries called in a complaint at approximately 100pm. No damage was observed or reported. CONCLUSION: There are several factors that may have contributed to the high airblast.They are: 1) Build-up of relatively unconfined gas during detonation, in the voids, venting through an undetected seam on the face. 2) A thermal inversion in effect at time of blast may have focused the overpressure. 3) Freeze - thaw causing rock to spall off the face, exposing a path for venting to occur. 4) Rock fractured or displaced by hole # i exposing the voids or seams in those holes that had them, allowing venting to occur. ( This is the most likely and significant contributor ) . Page 2 CORRECTIVE MEASURES: It is difficult to verify or predict the exact geologic conditions effecting a blast. They are in many cases dynamic as the rock shifts under its own weight; or even the movement of an explosives delivery system. Certainly as the detonation sequence progresses the enormous forces can create situations which are difficult to account for. We do, however allow for these variances with proper planning, shot design and lay -out. This is followed by appropriate drilling methods, and re -checking the lay -out before blasting. Careful and methodical loading and hook-up are essential to obtaining desired resullts. Safety is our number one priority, and will not be sacrificed. We challenge ourselves every day to perform our job safer, to do it better, and to minimize our effect on the surrounding environment. Sincerely, Robert A.

We have evaluated the blast and procedures in order to determine the causes of the excessive air blast level recorded from the blast of November 4, 1996 at 9:21 am, and make recommendations Y'J that m-y apply to f�ut9-e considerations liir co1ilphiance. - J Our review includes observations of the drilling, loading, weather condition, seismic recording equipment a, id incidental information. Given below is our pertinent observations: The seismograph, EVERLERT 1I; #7179 was factory/laboratory calibrated on Septe ber 10, 1996. 1t is working accurately and correct in its observations. Atmos heric conditions included temperature inversions existing for the day (Nover iber 4, 1996). Face c nditions indicated some fracturing and an undercut feature at zero time detonation (No. I hole). lntem drill hole condition along the face at initial hole (zero) time suggests a substantial void existed and a hot spot may have been created. The tr Ice velocity along the open face was approximately Tv = 520'/sec. Time df detonation (9:21 am), early morning conditions being cooler could ampli4 above ground surface transmission. VIERR—TECH ENGINEERS 4049855583 P.02 I L/O RD 7 -L- A re ' iew of the seismic records indicates a recording to blast distance of approximately 1980 feet and a definite impulse wave occurring very early in the detonation process (at 12 Hertz). PROBABIIE CAUSE: While atmospheric conditions may have contributed, somewhat, to the excessive air kT-'* vaua, rvG feel ine molo probable cause was internal geologic conditions (fracturing and voids) that contributed gases venting directly through the first row face. This is substantiated by the impulsive, of late venting of the air blast trace (Enclosed). CORR.EC WE CONSIDERATIONS: Closer cam unication between the driller and explosives personnel. Voids and fracturing are quite disce ible during the drilling process and this information should be shared and required by the loadi g personnel. 1kr Inversions should be avoided when possible. The seismog aph calibration was checked and found to be in perfect working order. The recordkeeping process at Benchmark Carolina Aggregates is excellent.

Tracy Forward Header Subject: Re: Benchmark Carolina Mine U.S. #1 N. of Raleigh Author: "Holley, John L." <N1LQ440@rro.ehnr.state.nc.us> at Internet Date: 1/14/97 3:52 PM I discussed this with both Terry and Steve Edgerton today. Steve informs me that the area they are considering is near the south end of their property behind Burlington Mills, between the railroad and the river. This area is within their permitted area, but not within their approved affected area. Their intent would be to lease the area to NCDO'T for operation of a mulch stockpile/ processing site. They would expect NCDOT to prepare a S&E plan and maintain the site. Benchmark Carolina would likely have access to use some of the mulch for their reclamation activities as well. i reminded Steve that 'this change would require a permit modification addressing the area to be affected by the operation (including access/haul roads). I noted that Benchmark Carolina would be responsible for compliance at the site under the Mining Act. He acknowledged his understanding of this scenario. I noted that I did not see any immediate concerns with the proposal, and that we would be happy to facilitate the arrangement as much as possible in light of the potential savings to the state and taxpayers. I suggested that he contact you or your staff to discuss the particulars if they elect to move forward with the proposal.
