Wake Stone Corporation Triangle Quarry Mining Permit No. 92-10 Modification Application April 8, 2020 NORTH CAROLINA MINING PERMIT APPLICATION State of North Carolina Department of Environmental Quality Division of Energy, Mineral, and Land Resources 1612 Mail Service Center Raleigh, North Carolina 27699-1612 (919) 707-9220 Revised: 2017 North Carolina Mining Permit Application State of North Carolina Department of Environmental Quality Division of Energy, Mineral, and Land Resources 1612 Mail Service Center Raleigh, North Carolina 27699-1612 (919) 707-9220 Wake Stone Corporation Triangle Quarry Mining Permit No. 92-10 Application for Modification of Mining Permit April 8, 2020 Background Through a Mineral Lease agreement with the Raleigh -Durham Airport Authority (RDUAA), Wake Stone Corporation has the opportunity expand its Triangle Quarry operation. This quarry expansion will allow the continued production of quality crushed stone products for the local market from our existing stone processing and delivery infrastructure at the Harrison Avenue location in Cary, NC. Additionally, through royalty payments to be made to RDUAA under the terms of the mineral lease, RDUAA will receive an estimated $24M over the projected 30-year mine life at a time when RDUAA requires funding for needed capital improvements. Since January 2016 Wake Stone has meticulously investigated the viability of establishing a quarry pit on the 106+/- acre RDUAA's Odd Fellows tract. Through exploration drilling and other due diligence activities we have formulated a plan for expanding the existing Triangle Quarry. This Mining Permit Modification Application package provides the details of our proposed expansion activities. Connectivity RDUAA's Odd Fellows tract is located directly across Crabtree Creek from the current Triangle Quarry pit. In order to safely and efficiently move equipment and transfer mined stone between the proposed new pit and the existing processing equipment, a bridge will be constructed across Crabtree Creek. Wake Stone has engaged the services of Michael Baker International (Baker), a recognized leader in transportation infrastructure engineering, to assist in the engineering design and construction permitting for a bridge structure suitable for use in mine truck haulage of stone to the existing processing facilities. Baker's services include the examination of any potential FEMA/100-Year Floodway and Neuse River Riparian Buffer Rule (NRB) impacts. Baker has, through Sungate Design Group, PA, submitted a No Impact Certification to Wake County Environmental Services (copy included in Appendices). Wake County Environmental Services concurrence on the No Impact Certification will be forwarded to NCDEMLR upon receipt. Minor NRB impacts, which are deemed allowable for bridge construction, are being addressed under a separate application being filed with NCDWR. Site development planning has also incorporated engineering designs for improvement to be made to the pit perimeter roadway around the north side of the existing Triangle Quarry pit. These improvement include lowering the roadway and the installation of engineered retaining walls and other sound/visual barrier structures installed for the purpose of minimizing any potential impacts to the users of Umstead State Park. Throughout our due diligence period we have acknowledged stakeholders' concerns about truck haulage on Old Reedy Creek Road and have maintained that no quarry products (including overburden) will be hauled from the site via Old Reedy Creek Road. Installation of the planned bridge over Crabtree Creek will facilitate overburden removal through the existing quarry site and Harrison Avenue entrance, negating the need for customer truck traffic on Old Reedy Creek Road. If the off -site demand for overburden falls short of the pace of stripping, the old Triangle Quarry pit will be used for storage of overburden. Once overburden removal activities are well underway and the initial pit has been established, we will have a better understanding of the construction industry's interest in utilization of our overburden for area construction projects. We will also determine the most efficient methods of handling the overburden based upon its unique characteristics, and the need to explore other potential material transportation methods. If alternative material transportation methods are found to be viable within the mining permit boundary, a permit modification request will be submitted for DEMLR review and approval. Aquatic Resources — streams and wetlands An integral part of Wake Stone's due diligence activities has been the identification of and determination of jurisdictional status of any on -site streams, wetlands, or other aquatic resources. Soil and Environmental Consultants, PA was retained to perform a detailed delineation of any such features using standard US Army Corps of Engineers (USACE) and North Carolina Division of Water Resources (NCDWR) jurisdictional determination procedures. The limits of all identified aquatic resources were confirmed through on -site consultations with representatives of the USACE and NCDWR, and a survey plat prepared by a licensed land surveyor. Following those site visits, the USACE issued an Approved Jurisdictional Determination (AJD) and NCDWR issued a Buffer Determination Letter. (These documents are included in this Mining Permit Application package.) Wake Stone has planned and designed its site development activities in such a manner as to avoid impacts to any jurisdictional aquatic resources. Mitigation of Perceived Impacts to the Public Through our due diligence process, we have been subjected to numerous public complaints via social media and other outlets. We acknowledge that some members of the public may not think the Odd Fellows tract is a suitable location for a quarry pit, and that establishment of such will have an adverse effect on their usage of the Old Reedy Creek Road greenway and Umstead State Park. We take those concerns seriously and have devised our site development plans in such a manner as to mitigate those concerns. As detailed in the application booklet and accompanying site plan maps, we intend to retain ample buffers along the Old Reedy Creek Road and Umstead Park boundaries. These buffers, including the planned construction of expansive vegetated earthen berms, will provide sufficient set -back distances and visual and sound barriers from users of Old Reedy Creek Road and Umstead State Park. The perimeter earthen berms will be installed as early in the site development period as possible. As illustrated on the site development plans, pit development activities have been planned to initially occur only on the eastern side of the Odd Fellows tract, keeping mine development activities as far removed from the public as possible. Planned Site Development Incorporated in the application material are detailed plans for development of the new quarry pit and ancillary features on the Odd Fellows tract, including a detailed sequence of development activities. Once the Mining Permit Modification is approved by NCDEQ/DEMLR, we will begin expansion activities according to these detailed plans. Improvements to the existing pit perimeter road and construction of the bridge will coincide with initial site work on the Odd Fellows tract, including construction of the perimeter earthen berms. Our intention is to complete berm construction as early as possible in order to screen the site from public view. Erosion and sediment control structures have been designed in accordance with NCDEQstandard specifications. Details for all erosion and sediment control structures are provided in the application materials and Erosion and Sediment Control Plan designed by Piedmont Land Design, LLP. Post -Mining Site Reclamation As detailed in the mineral lease agreement between Wake Stone and RDUAA and further discussed in this Mining Permit Modification Application, Wake Stone is committed to reclaim the 106-acre site post -mining with features such as overlooks, greenway trails, parking areas, pit security fencing, with connectivity to Umstead State Park. The details of such reclamation activities will be determined by RDUAA and Wake Stone upon completion of mining activities. As stated in the April 3, 1981 Final Decision of the Mining Commission (pursuant to issuance of the initial mining permit for Triangle Quarry), Wake Stone will continue to be obligated to offer to the State the original Triangle Quarry "quarry site" as defined in the Mining Commission decision document. Permit Denial Criteria The Triangle Quarry has been successfully operated since 1981 without invoking any of the seven permit denial criteria dictated by the North Carolina Mining Act, and in compliance with applicable mining, water discharge, and air quality regulations. State and Federal permitting and required monitoring under the NPDES/Stormwater and Air Quality programs ensure that continued operation of the quarry will not have adverse effects on wildlife or fisheries, or violate any air or water quality standard. Existing natural vegetation buffers and proposed vegetated earthen berms will screen the expanded operation from public view. These buffers and vegetated berms will provide adequate buffering for neighboring residences, vehicular and foot traffic along Old Reedy Creek Road, and visitors to Umstead Park. Designated buffers, stabilized overburden cut slopes, safe blasting practices, and proposed high wall barriers will ensure the prevention of physical hazard to any neighboring structures or properties. Wake Stone Corporation has operated the Triangle Quarry since 1981 without violation of any of the State or Federal regulations governing mining. Through implementation of well - designed mining plans and sediment and erosion control plans, sediment deposition in adjoining waterways has been prevented. Undisturbed vegetated buffers along Crabtree Creek and the Umstead State Park boundary provide adequate buffering to prevent sediment deposition in the creek, while providing visual and sound buffering of the operation. Umstead State Park has thrived during the past 39 years, becoming one of the most popular state parks in North Carolina. Based upon the information provided in the attached permit modification application, Wake Stone firmly believes Umstead State Park will continue to prosper as we operate on the RDUAA Odd Fellows property. Our intention is to continue to operate as we have for the past 39 years, with a dedicated commitment to permit compliance and environmental stewardship.

PROTECTION OF NATURAL RESOURCES Describe in detail the sequence of events for the development and operation of the mine and reference the sequence to the mine map(s). Attach additional sheets as needed. See narrative discussion of sequence of land disturbing activities on the following pages and reference generalized sequence as presented on the Erosion and Sediment Control Plan by Piedmont Land Design, L.L.P. 2. Describe specific erosion control measures to be installed prior to land disturbing activities and during mining to prevent offsite sedimentation (include specific 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 are required to justify the adequacy of any proposed measures. See the following pages for a narrative discussion of proposed Erosion and Sediment Control Structures to be employed prior to initiation of land disturbing activities and reference generalized sequence as presented on the Erosion and Sediment Control Plan by Piedmont Land Design, L.L.P. 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. Washed stone products will continue to be produced at the Triangle Quarry, as they have throughout the history of the quarry operation. These NC DOT specification products are screened to size and washed at the secondary plant's rinse screen. Plant process water is retained in the water supply reservoir and settling cells for recycling/re-use. All process water is maintained in a closed -loop recycle system with a minimum of 1 foot of freeboard at the process reservoir to ensure that no process water is discharged. Wash water is pumped from the supply reservoir to the wash plant for use in washing of stone as it crosses the rinse screen. This process water is then routed through a double screw classifier ("sand screw") for capture of coarse mineral fines in the production of "Classified Screenings". Overflow from the sand screw is pumped to an array of hydro -cyclones for removal of mineral fines. These mineral fines are dewatered across a high frequency de -watering screen, and are then incorporated into the "Processed Fill" product stockpile. Following recovery of fine and coarse mineral particles, the remaining effluent is routed through two settling cells for removal of ultra -fine mineral particles prior to being returned to the process water reservoir for recycling as the final step in this closed -loop water recycle system. Hychem HYPERFLOC CP 757, an organic cationic coagulant liquid, is metered in small volumes into the process water stream at the sand screw overflow in order to increase settling efficiency in the settling cells. b. Will the operation involve discharging fresh or waste water from the mine or plant as a point discharge to the waters of the State? Yes X No ❑. If yes, briefly describe the nature of the discharge and locate all proposed discharge points (along with their method of stabilization) on your mine map(s). Pit dewatering effluent is periodically discharged to an unnamed tributary to Crabtree Creek under the provisions of Stormwater General Permit Number NCG020001. Plant process water is retained on - site in the previously described closed -loop water recycle system. -7- APPLICATION FOR A MINING PERMIT Sequence of Land Disturbing Activities Detailed Construction Sequence for Triangle Quarry RDU Expansion 1. Secure Mining Permit modification approval, FEMA "no rise" certification for bridge construction, and NC DWR notifications of allowable buffer impacts for bridge construction. 2. Improve existing construction entrance on RDU property as shown on E&SC Plan for logging and initial site preparation. 3. Remove Trees for 59.3 acre RDU expansion and for 2.9 acre Triangle Perimeter road improvements as illustrated as "Clearing Limits" on PLD E&SC Plan. Logging activities will utilize Old Reedy Creek Rd for log Transport. 4. Stake out and Install silt fence and/or super silt fence as shown on PLD E&SC Plan (Sheets 2, 3, 8, and 9). 5. Construct Temporary Sediment Basin 7 and associated diversions as illustrated on PLD E&SC Plan (Sheet 8). Stabilize disturbed areas with vegetation as specified in PLD E&SC Plan (Sheet 11). 6. Once appropriate E&SC measures are installed around Triangle Quarry perimeter road improvement areas, construction will begin at the easternmost point and progress to the west. The proposed method of construction for the cut areas of the road will ensure all drainage is diverted into the existing pit via super elevation of the road surface as illustrated by cross sections on WSC Site Plan (Sheets 7 and 9). Engineered retaining walls along fill areas will be constructed and fill placed and compacted to ensure all drainage is diverted into the existing pit or to Temporary Basin 7 as shown on PLD E&SC Plan (Sheets 8 and 9 ). Safety berms, large boulder barricades, or concrete block barricades will be utilized to meet MSHA safety requirements along any rollover hazard areas. This phase of perimeter road improvement will also include filling and grading of pre-existing SDO-4 basin and Temporary Basin 7 to divert all stormwater runoff to the existing pit. Noise and visual abatement will be provided along Umstead State Park facing areas by the inclusion of a 14' high solid barrier where needed as shown by cross sections on WSC Site Plan (Sheet 9). 7. Construct Temporary Sediment Basins 1, 2, and 3, including installation of culverts under proposed berm in the locations shown on PLD E&SC Plan, and all associated diversion ditches/swales and slope drains (Sheets 4 and 5). Stabilize disturbed areas with vegetation as specified (Sheet 11). 8. Once required E&SC measures are in place, construction of the proposed RDU perimeter visual barrier berm and perimeter access road will begin. Berm construction will begin at the western end to provide visual and noise buffer along the Old Reedy Creek Road corridor. In order to minimize impacts and disturbed area, the footprint of the berm will be utilized for haulage of overburden material used for construction of the berm. The construction entrance will be relocated to the southwest as berm construction continues around the Dunn residence and along the Umstead Park boundary, as illustrated on PLD E&SC Plan (Sheet 6). 9. Grade construction areas on either side of the proposed bridge crossing in preparation for bridge construction. All graded areas shall be diverted to Temporary Basin 3, Temporary Basin 7, or to the existing Triangle Pit for sediment control prior to discharge under existing NCG02 permit as either stormwater or pit-dewatering wastewater as required. Material excavated from the 280' elevation on the RDU site in preparation for the bridge construction will be placed as fill material for the vegetated perimeter berm. 10. Install onsite concrete washout structures as specified in PLD E&SC Plan (Sheet 10). 11. Bridge construction will begin with the pouring of concrete abutments, girder placement, decking, and guardrail concrete pours. This construction will be performed in accordance with bridge design drawings APPLICATION FOR A MINING PERMIT permitted through Wake County. Bridge construction traffic may use Old Reedy Creek Rd if needed for access. 12. Construct Temporary Sediment Basin 4 and associated "Phase 1" diversions and slope drain. Stabilize disturbed areas with vegetation as specified In PLD E&SC Plan (Sheet 5). 13. Construct Temporary Sediment Basins 5 and 6 as shown on E&SC Plan (Sheet 5). Stabilize disturbed areas with vegetation as specified in PLD E&SC Plan (Sheet 11). 14. Once all "Phase 1" E&SC measures are installed, stumping and grubbing of initial pit area can commence. However, upon completion of the proposed vegetated berm, no further excavations will proceed until bridge construction is complete, and overburden material can be hauled across the bridge and either end - dumped into the depleted existing quarry pit as indicated on WSC Site Plan (Sheet 7 and 8), or taken offsite as borrow material via the existing quarry entrance at Star Lane. No overburden or rock traffic will exit the site via Old Reedy Creek Rd. 15. Once the bridge construction is complete AND the existing quarry perimeter road improvements are complete, production drilling and blasting activities will begin on the RDU expansion area. Weathered rock material will be hauled to the existing in -pit primary crusher and run through the existing process plant as "processed fill" as needed by market demand, or else end -dumped to the depleted existing quarry pit. Blasted stone will be hauled across the bridge to the existing in -pit primary and processed as NCDOT specified products stockpiled and sold from the same yard, scale, and entrance locations as the existing operation. 16. The current pit sump will remain in place at an elevation currently estimated to be at least 130' above the final pit floor elevation, maintaining separation of water used for make-up water for the process water reservoir and/or discharged as pit dewatering wastewater. Smaller portable pumps may be utilized to transfer water from lower pit levels (as they are currently) to the sump as needed. 17. As stripping continues around the southern perimeter of the RDU property, the "Phase 2" diversion will be constructed in conjunction with a future pit perimeter road to carry all stormwater runoff to Temporary Basin 4. Temporary Basins 5 and 6 will be removed as this new diversion will render them obsolete as illustrated in PLD E&SC Plan (Sheet 7). 18. Early stages of pit development may include sinking a ramp down along the inside of the new RDU pit perimeter road. As this excavation advances to the south, all accumulated stormwater and groundwater will be pumped to the existing Triangle Quarry pit, and managed under current NCG02 guidelines. 19. As the new pit development progresses to the south, eventually Temporary Sediment Basin 4 will also be removed and incorporated into overburden cut slope for the new mine pit as shown on WSC Site Plan (Sheet 5). At that point, all disturbed areas will drain to the new pit, and all accumulated stormwater and groundwater will be stored as needed or pumped to the preexisting pit for treatment and use, or discharged at the existing approved discharge location under NCG02. The earthen embankment and perimeter road will remain to provide flood protection from Crabtree Creek and to provide perimeter access for the newly established mine pit. I� APPLICATION FOR A MINING PERMIT Erosion and Sediment Control Erosion and sediment control structures to be utilized during site development activities consist of graded earthen diversions, temporary (skimmer type) sediment basins, standard silt fencing, and "super" silt fencing. All such structures are illustrated on the accompanying site development plans, with construction details and engineering design calculations provided in the Erosion and Sediment Control Plan documents prepared by Piedmont Land Design, L.L.P. (PLD). Stabilized Construction Entrance During initial site development activities (including timber removal) access will be via the existing site entrance driveway located adjacent to the Dunn property on Old Reedy Creek Road. This driveway has been improved to "temporary construction entrance" design specifications during Wake Stone's due diligence period. The drive is stabilized with Class A/Surge rip rap and secured by a locking cable gate. As planned perimeter berm construction advances to the point of rendering this entrance obsolete, a new construction entrance will be installed at the southwest terminus of the Old Reed Creek Road berm. Construction details for this secondary entrance are provided in the PLD documents and will consist of geotextile underlayment beneath Class A/Surge rip rap. An NCDOT driveway permit will be applied for and obtained prior to initiation of construction of this new construction entrance. Silt Fencing / Super Silt Fencing Silt Fencing and Super Silt Fencing will be utilized along disturbance limits as illustrated on the site development plans. Construction details for silt fencing and super silt fencing are provided in the PLD Erosion and Sediment Control Plan drawings and details. Graded earthen diversions Numerous graded earthen diversions are to be utilized to direct runoff from disturbed areas to planned skimmer sediment basins. Construction and stabilization details for the proposed temporary diversions are provided in the PLD Erosion and Sediment Control Plan documents. Skimmer type temporary sediment basins Skimmer type temporary sediment basins will be utilized for sediment containment and stormwater collection during early site development activities. Proposed Sediment Basins 1 through 7 are illustrated on the site development plan drawings with construction details and supporting engineering calculations provided in the PLD Erosion and Sediment Control Plan. All proposed basins will be provided with fabric baffles and surface dewatering (skimmer) devices. Principal spillway pipes and emergency spillways will be stabilized with geotextile or rip rap pads as indicated in the PLD plan set. Installation sequence and maintenance of structures The sequence for installation of proposed Erosion and Sediment Control structures is provided in the previous discussion of "chronological sequence of land disturbing activities". Structures will be inspected daily and following each rainfall event with potential to generate runoff. Temporary diversions and silt fencing will be repaired as necessary should inspections dictate the need for maintenance or repair. Sediment accumulated behind silt fencing will be removed and fencing repairs undertaken as needed. Temporary sediment basins will be inspected following each rainfall event. Accumulated sediment will be removed once it reaches 50% of the sediment containment capacity. Repair or replacement of basin baffles will be undertaken on as needed basis as determined by periodic inspections. -10- APPLICATION FOR A MINING PERMIT c. Will any part of the proposed mine excavation(s) extend below the water table? Yes X No ❑. If yes, do you intend to dewater the excavation(s)? Yes X No ❑. If yes, what impact, if any, will mine dewatering have on neighboring wells? Estimated withdrawal rate in gallons per day: 5-Yr. ave. = 0.199 MGD. Locate all existing wells on the mine map(s) that lie within 500 feet of the proposed excavation area. Provide data to support any conclusions or statements made, including any monitoring well data, well construction data and current water withdrawal rates. Indicate whether the proposed mine locale is served by a public water system or private wells. Stormwater runoff and minor groundwater infiltration into the existing Triangle Quarry pit is collected within the pit sump for retention, transfer to the process water closed -loop system as make-up water, or discharged to an unnamed tributary to Crabtree Creek under the provisions of NCG0200001. Daily withdrawal and discharge records are maintained in the quarry office and are tabulated and reported to the NC Division of Water Resources annually pursuant to the requirements of NCGS 143-215.22H. These reported data indicate a 5-year (2014-2018) average daily withdrawal of 0.199 MGD of comingled groundwater and collected stormwater. Gauging of recently installed groundwater monitoring wells on the RDU Odd Fellows tract document only very minor impacts have occurred to the regional crystalline rock aquifer as a result of decades of dewatering of the Triangle Quarry pit. Although fractured and strongly foliated, the crystalline rock mass actively being mined at the Triangle Quarry, and that to be mined on the expansions site, exhibit low hydraulic transmissivity, resulting in very low groundwater infiltration rates. Based on historical pit dewatering data and measurement of static groundwater levels encountered in recently installed monitoring wells, we do not anticipate any adverse effect to the single (Dunn residence) domestic water supply well (identified on the Site Plan Map) which is located within 500 feet of the proposed pit excavation area. A permanent groundwater observation well (PMW-1) has been installed near the southeast corner of the Dunn property boundary (see Site Plan Maps). Periodic monitoring of the static groundwater elevation within this permanent well and the previously mentioned temporary wells (OW-1, OW-2, OW-3, and OW-4) will allow observation and documentation of any groundwater fluctuations as development of the proposed new mine pit progresses. Measured groundwater elevation data will be reported to NC DEQ DEMLR on such frequency as deemed necessary by DEMLR/DWR once the modified Mining Permit is issued. (Note: The aforementioned groundwater observation wells were approved by (and constructed in accordance with the well construction standards administered by) the North Carolina Division of Water Resources. Reference the enclosed Well Construction Permit and Well Construction Record (GW-1) forms.) Once mining commences on the expansion site, should monitoring well data conclusively prove adverse impacts have occurred (groundwater surface lowered to an elevation to render the Dunn residence well inoperative), Wake Stone will take steps as necessary to mitigate the loss of service of the Dunn's well, up to and including installation of a replacement well. (Refer to hydrogeological assessment by GMA, Inc. and well construction permit and completion records as filed with NC DWR appended to this application booklet.) d. 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 Stormwater Program. In addition, the applicant is required to register water use with the Division of Water Resources, Ground Water Management Branch, if the operation withdraws more than 10,000 gallons per day and needs a capacity use permit from the Division of Water Resources, Ground Water Management Branch, if the operation lies in a capacity use area and withdraws more than 100,000 gallons per day.

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. Reference attached Cover Sheets for NC DAQ Air Permit No. 043861115. b. How will dust from stockpiles, haul roads, etc., be controlled? Triangle Quarry currently utilizes two 8,000-gallon capacity water trucks in the control of haul road and stockyard fugitive dust emissions. Fugitive emission from plant processes (crushers, sizing screens, and conveyor transfer points) are controlled via the application of water sprays, or screen enclosures. The same control methodologies will be employed for the proposed expanded pit operation. 5. a. A buffer will be required between any mining activity and any mining permit boundary or right- of-way. It may be an unexcavated buffer (no excavation, but roadways, berms and erosion & sedimentation control measures may be installed within it), an undisturbed buffer (no disturbance within the buffer whatsoever), or a combination of the two, depending upon the site conditions. Note that all buffers must be located within the mining permit boundaries. How wide a buffer will be maintained between any mining activity and any mining permit boundary or right-of-way at this site? A minimum buffer of 25 feet is recommended, although a wider buffer may be needed depending on site conditions. Show all buffer locations and widths on the mine map(s). Proposed permanent buffers are illustrated on the accompanying Site Plan and Erosion and Sediment Control Plan drawings. • Old Reedy Creek Road Right -of -Way: A 100' unexcavated buffer is proposed along the Old Reedy Creek Road right-of-way property boundary. (Earthen berm construction, E&SC structures, and security fencing will occur within this buffer.) • Dunn Property and northern boundary with Umstead State Park: A 100' unexcavated buffer is proposed along these adjoining properties. (Earthen berm construction, E&SC structures, and security fencing will occur within this buffer.) • Crabtree Creek: A 100' (as measured from the property line/centerline of Crabtree Creek) undisturbed buffer is proposed. (Pursuant to and in accordance with the Raleigh Durham International Airport Authority's proposed security fencing plan, fencing will likely be installed within the 100' unexcavated buffer along Old Reedy Creek Road and the Dunn and Umstead State Park boundaries.) Should RDU proceed with their proposed security fencing plan prior to Mining Permit issuance, installed fencing will be according to their proposed design. Should RDU elect not to proceed with the proposed fencing plan, Wake Stone will install appropriate security fencing to prevent inadvertent public entry into the mine site. A conceptual fencing design is illustrated on the Site Plan drawing set. -12- NORTH CAROLINA ENVIRONMENTAL MANAGEMENT COMMISSION DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES Issue Date: August 30, 2013 Expiration Date: July 31, 2021 DIVISION OF AIR QUALITY AIR PERMIT NO.04386R15 Effective Date: August 30, 2013 Replaces Permit: 04386R14 To construct and operate air emission source(s) and/or air cleaning device(s), and for the discharge of the associated air contaminants into the atmosphere in accordance with the provisions of Article 21 B of Chapter 143, General Statutes of North Carolina (NCGS) as amended, and other applicable Laws, Rules and Regulations, Wake Stone Corporation - Triangle Quarry 222 Star Lane Cary, Wake County, North Carolina Permit Class: Small Facility ID# 9200409 (the Permittee) is hereby authorized to construct and operate the air emissions sources and/or air cleaning devices and appurtenances described below: Emission Emission Source Control Control System Source ID Description System ID Description ,Non -Metallic Mineral Processing Plant, utilizing water suppression with no other control ;device, including: ES -Crushers (NSPS) ;crushing operations N/A j N/A ES -Conveyors (NSPS) conveyor operations N/A N/A I ES -Screens (NSPS) iscreening operations j N/A� N/A in accordance with the completed application 9200409.13A received August 21, 2013 including any plans, specifications, previous applications, and other supporting data, all of which are filed with the Department of Environment and Natural Resources, Division of Air Quality (DAQ) and are incorporated as part of this permit. This permit is subject to the following specified conditions and limitations including any TESTING REPORTING, OR MONITORING REQUIREMENTS: APPLICATION FOR A MINING PERMIT b. A minimum 50 foot wide undisturbed buffer will be required between any land disturbing activities within the mining permit boundaries and any natural watercourses and wetlands unless smaller undisturbed buffers can be justified. Depending on site conditions, a buffer wider than 50 feet may be needed. How wide an undisturbed buffer will be maintained between any land disturbing activities within the mining permit boundaries and any natural watercourses and wetlands at this site? Show all buffer locations and widths on the mine map(s). Pursuant to NCDEMLR and NCDWR program policies, a minimum 50' undisturbed buffer will be maintained between mining related activities and jurisdictional wetlands and waters. All jurisdictional wetlands and waters are identified on the accompanying USACE Approved Jurisdictional Determination plat and NC DWR Neuse River Buffer Determination. No jurisdictional wetland or waters impacts are proposed at this time. No Neuse River Riparian Buffer impacts are proposed with the exception of allowable impacts associated with construction of the proposed bridge for access to the pit expansion area. 6. a. Describe methods to prevent landslide or slope instability adjacent to adjoining permit boundaries during mining. 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. Analyses of soil and decomposed rock material encountered during exploration drilling indicate overburden cut slope stability will be attained through establishment of 2 horizontal to 1 vertical gradients. During overburden removal, cut slopes will be established at 2HAV gradient and stabilized with vegetative cover as soon as practicable. Should differing soil/saprolite conditions encountered during overburden removal warrant a different slope arrangement, necessary adjustments to final gradient will be made as such conditions are encountered. Given the proposed setback distance between the permit boundaries and the top of any proposed cut slope (reference Site development plan maps), the risk of landslide or slope instability is not of concern. b. Provide a cross-section on the mine map(s) for all fill slopes (berms, waste piles, overburden disposal areas, etc), clearly indicating the intended side slope gradient, installation of any benches and/or slope drains (with supporting design information) if needed, and the method of final stabilization. See Site Plan drawings for typical perimeter berm construction (cross sectional) details. c. In excavation(s) of unconsolidated (non -rock) materials, specify the angle of all cut slopes including specifications for benching and sloping. Cross -sections for all cut slopes must be provided on the mine map(s). See 6.a. above: Overburden cut slopes are proposed to be established at 2H:1V. Provisions will be made for retention of a 12' wide safety bench between the toe of overburden cut slopes and the top of rock cut faces. See Site Plan drawings for typical overburden cut slope (cross sectional) details. d. In hard rock excavations, specify proposed bench widths and heights in feet. Provide cross - sections of the mine excavation clearly noting the angles of the cut slopes, widths of all safety benches and mine benches, and the expected maximum depth of the excavation. See Site Plan drawings for proposed typical pit bench details. The new pit will be developed with 50' face heights, with 12' wide safety ledge retained between benches. -13- APPLICATION FOR A MINING PERMIT 7. Describe other methods to be taken during mining to prevent physical hazard to any neighboring dwelling house, public road, public, commercial or industrial building from any mine excavation. Locate all such structures on the mine map if they are within 300 feet of any proposed excavation. In the case of the Triangle Quarry expansion project proposed for the RDU Odd Fellows tract, only one such neighboring dwelling house (Dunn residence) and one such public road (Old Reedy Creek Road) are located within 300' of any currently proposed or potential future mine excavation area. No public, commercial, or industrial buildings are located within 300' of the currently proposed, or potential future pit development area. As illustrated on the accompanying site development plan maps and Erosion and Sediment Control Plan maps, a 15' high vegetated earthen berm is to be constructed along the property boundaries bordering the Dunn residence, Old Reedy Creek Road, and Umstead State Park. Once completed, this berm (and associated setback distances) will prevent the possibility of any physical hazard, and minimize any visual and sound impacts, that might be associated with development of the mine site. As in the currently operating Triangle Quarry, blasting activities will be conducted in strict adherence to standard industry practices designed to minimize air blasts and ground vibrations, and prevent the occurrence of fly rock. (See response to Question 11.) 8. Describe what kind of barricade will be used to prevent inadvertent public access along any high wall area and when it will be implemented. 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). Protection against inadvertent public entry along any high wall area, and the mine site in general, will be provided by the proposed vegetated earthen berm to be constructed along Old Reedy Creek Road frontage and the Dunn and Umstead State Park property boundaries. Additionally, fencing will be installed within the unexcavated buffer area retained between the outside berm toe and the property/permit boundary. Specific fence design will either be that proposed under the RDUAA's security fencing plan or Wake Stone will install appropriate security fencing to prevent inadvertent public entry into the mine site. Either fence design will limit inadvertent public entry into the mine site. Vegetated earthen berm construction will be initiated as soon as possible upon issuance of the modified mining permit. Installation of fencing will be dependent upon final resolution of RDUAA's security fencing plan and/or timing of the issuance of the mining permit modification. -14- APPLICATION FOR A MINING PERMIT 9. Are acid producing minerals or soils present? Yes ❑ No X. If yes, how will acid water pollution from the excavation, stockpiles and waste areas be controlled? Examination of exploration drilling core samples indicates the presence of trace amounts of pyrite within the bedrock to be mined. The amount of pyrite present is similar to that occurring in other bedrock deposits throughout the piedmont of North Carolina. Due to the very low background pyrite content, generation of "acid water" is not anticipated. 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 map(s) and provide cross - sections through all proposed berms or proposed spacing, sizes and species for tree plantings. As illustrated on accompanying site development maps and within the Erosion and Sediment Control Plan, Wake Stone intends to construct a 15' high visual barrier berm along the Old Reedy Creek Road, Dunn Property, and Umstead State Park boundary (limited to the area west of the existing lake commonly referred to as "Foxcroft Lake"). This berm will be installed during the initial stages of site development in order to provide immediate visual screening. The visual barrier berm will be planted with grasses (for soil/slope stabilization) and perhaps native tree and/or shrub species for esthetic purposes. 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? Since Wake Stone Corporation's Triangle Quarry began operations in 1981, there has been no evidence of it having an adverse effect on Umstead Park or its visitation. In fact, it has often been touted as the state's most visited park. Please see the attached visitation records supplied by the North Carolina Division of Parks and Recreation. Anecdotally, we most often hear "we did not know a quarry was even there." Visibility: Although Old Reedy Creek Road is utilized by pedestrians and bicyclists as a Park point of entry via the multi -use trail system, the vegetated visual barrier berm planned along this Permit/property boundary will mitigate quarry visibility concerns. Similarly, the berm planned along the common boundary between the Odd Fellows tract and the Umstead Park will provide visual screening of the operation for those park visitors that might utilize this non -trail section of the park. These berms, combined with the proposed fencing, will prevent inadvertent public entry into the quarry operation by park visitors. Noise: In planning for the RDU tract expansion of the Triangle Quarry pit, Wake Stone has included provisions for minimizing potential noise impacts on park visitors. Construction of the visual barrier/noise attenuation vegetated earthen berms is one such provision. Another such provision is inclusion of concrete block walls as an integral part of the proposed north pit perimeter road improvements. Likewise, the connector bridge to be constructed across Crabtree Creek will be located as remote to the park property as possible given existing site/topography conditions (reference site maps for bridge location). No increase in quarry generated noise is anticipated above the historic levels. -15- Umstead Park Visitation Data 2000-2020 3/25/2020 Park Year Visitation Y-O-Y Change MUM 2000 404,973 MUM 2001 401,633 (3,340) MUM 2002 387,492 (14,141) MUM 2003 426,515 39,023 MUM 2004 477,475 50,960 MUM 2005 560,379 82,904 MUM 2006 596,793 36,414 MUM 2007 612,411 15,618 MUM 2008 722,732 110,321 MUM 2009 782,411 59,679 MUM 2010 876,993 94,582 MUM 2011 881,180 4,187 MUM 2012 1,175,077 293,897 MUM 2013 1,154,632 (20,445) MUM 2014 1,293,063 138,431 MUM 2015 1,342,650 49,587 MUM 2016 1,847,260 504,610 MUM 2017 1,538,830 (308,430) MUM 2018 1,145,568 (393,262) MUM 2019 951,111 (194,457) MUM 2020* 215,871 (735,240) *Data includes visitation from January 1 - March 23. 2020 Source: North Carolina Division of Parks and Recreation 2,000,000 1,800,000 1,600,000 1,400,000 1,200,000 1,000,000 800,000 600,000 400,000 200,000 Umstead Park Visitation History 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 Year APPLICATION FOR A MINING PERMIT 11. Will explosives be used? Yes X No ❑. If yes, specify the types of explosive(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 may be required on the blasting program (such as a third -party blasting study). Locate the nearest offsite occupied structure(s) to the proposed excavation(s) on the mine map and indicate its approximate distance to the proposed excavation. ANFO and emulsion blasting agents have been utilized for many years for production blasting at the Triangle Quarry. All blasting agents are brought on -site just prior to blasting and loaded in blast holes from contract bulk dispensing truck. No blasting agents are stored on -site. Blast hole drill logs are used in conjunction with laser face profiling and crushed stone stemming material to custom load each blast hole. Detonation of blasts is by electronic blasting caps utilizing a computerized timing system to maximize control of flying rocks, air blasts and ground vibrations. A seismograph is used to monitor each blast at the nearest offsite occupied structure. These procedures ensure well controlled blasts and greatly reduce the potential for flying rocks or excessive air blasts or ground vibrations. In addition, Wake Stone frequently uses Dyno Nobel, a nationally recognized explosives and blasting consulting firm, to assist us with our blasting. Using data collected from our current blasting program at the Triangle quarry, Dyno Nobel performed an analysis of expected air blasts and ground vibrations that might be expected for blasting within the new pit expansion on the RDU Odd Fellows tract. Their analysis confirms that blast events can be designed and performed to keep air blasts and ground vibrations in the expanded pit well below allowable limits for structures as close as 500' from the blast site. Dyno Nobel's blasting analysis summary report is included with this application. 12. Will fuel tanks, solvents, or other chemical reagents be stored on -site? Yes X No ❑. If yes, describe these materials, how they will be stored and method of containment in case of spill. Indicate the location(s) of all storage facilities on the mine map(s). Fuels and lubricants are stored at the existing quarry fuel/lube station. This covered structure is provided with a secondary containment wall and a roof covering. No fuel or lubricants will be stored on the RDU expansion site. The Triangle Quarry's mobile fuel/lube truck will be utilized for any fueling operations required on the expansion site in a similar fashion as used in the long-standing existing Triangle Quarry mining operation -16- APPLICATION FOR A MINING PERMIT D. RECLAMATION PLAN 1. 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 drainage channels to a condition minimizing erosion, siltation and other pollution. This information must be illustrated on a reclamation map and must correspond directly with the information provided on the mine map(s). In addition, design information, including typical cross -sections, of any permanent channels to be constructed as part of the reclamation plan and the location(s) of all permanent channels must be indicated on the reclamation map. Once depleted of mineral reserves, both pits will be allowed to fill with groundwater/surface water runoff to create lakes with water surface elevation at approximately +280' MSL. All plant components will be disassembled and removed. All stockpiles will be removed and the plant and stockpile areas graded to provide positive drainage. Bare land surfaces will be provided with vegetative cover according to future land use plans. Process water settling ponds and obsolete sediment basins will be backfilled and stabilized with vegetation. Post mining, portions of the current Triangle Quarry property (plant and stockpile areas) will likely be developed for commercial/office/residential uses. Opportunities will exist for creation of recreational facilities such as hiking/biking trails, nature trails, scenic overlooks, and expansion of the Capital area greenway trail network, as will the potential to incorporate portions of the mine site into Umstead State Park. As stated in the Mining Commission's Final Decision dated April 3, 1981, Wake Stone will continue to be obligated to offer to donate to the State the quarry site located on the property owned by Wake Stone. "The term, "quarry site", shall include the entire pit as it exists after quarrying has been completed, a strip extending at least 50 feet from the top of the slope of the pit on all sides (see reclamation plan for the requirements applying to the slope), and a reasonable area to connect the pit and surrounding strip to Umstead Park, constituting a total area of at least 75 acres." "When all quarryable stone has been removed from all of the land belonging to or controlled by Wake Stone Corporation during the period of its quarrying operations and which lies between Umstead Park and Interstate 40, it shall be the duty of Wake Stone to notify the State of this fact. Upon receipt of such notice, the State shall have six months within which it may elect to have Wake Stone convey the quarry site to the State. If the State elects to have Wake Stone convey the quarry site to the State, it shall notify Wake Stone of such election within said six month period. All notices shall be by certified mail with return receipt requested. If the State fails to make an election within said six month period or shall elect not to accept a conveyance of the quarry site, the option shall thereupon terminate and Wake Stone shall have no further obligation to convey the quarry site to the State." Since the onset of its investigation into the viability of establishing a quarry pit expansion on the RDU Odd Fellows tract, Wake Stone Corporation has recognized the post -mining value of the expanded Triangle Quarry site for recreational purposes. Early discussions with stakeholder groups included the presentation of Conceptual Plans illustrating potential future outdoor recreation -based development once mining is completed. The company recognizes that this project will provide an opportunity for a unique partnership between the company, the RDUAA, Wake County, and the State of North Carolina. The details of such a partnership, and how the depleted mine site might ultimately dovetail into the greater Umstead State Park/Capital Area Greenway system, is yet to be determined. As detailed in our Option and Lease Agreement, Wake Stone has committed to RDUAA to reclaim the Odd Fellows property with features such as overlooks, greenway trails, parking areas, pit security fence, and connectivity to the Triangle quarry. The precise location of these features will be determined by RDUAA and Wake Stone upon termination of mining activity and the lease interest. A conceptual rendering illustrating potential post -mining reclamation of the combined quarry site is provided as WSC Site Plan Sheet 10 in the site development plan set. -17- APPLICATION FOR A MINING PERMIT 2. Is an excavated or impounded body of water to be left as a part of the reclamation? Yes X No ❑. If yes, illustrate the location of the body(s) of water on the reclamation map and provide a scaled cross-section(s) through the proposed body(s) of water. The minimum water depth must be at 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 ❑. If yes, specify species. At the time of final reclamation, the North Carolina Wildlife Resources Commission will be contacted for assistance in determining the suitability of the post reclamation lakes for fish stocking. 3. Describe provisions for safety to persons and to adjoining property in all completed excavations in rock including what kind of permanent barricade will be left. Acceptable permanent barricades are appropriate fencing, large boulders placed end -to -end, etc. Construction details and locations of all permanent barricades must be shown on the reclamation map. Suitable fencing or concrete block walls, and warning signs will be erected along the property boundary where proximity to high walls constitutes a significant safety hazard. 4. Indicate the method(s) of reclamation of overburden, refuse, spoil banks or other such on -site mine waste areas, including specifications for benching and sloping. Final cross -sections and locations for such areas must be provided on the reclamation map. Other than the currently existing earthen berms, and those proposed for construction pursuant to this modification application, no other overburden storage piles, spoil banks, or other such mine waste areas exist or are anticipated. Earthen berms constructed of overburden, have, or will be constructed concurrent with mining. As such areas are completed, they will be stabilized and vegetated and remain as permanent features at the site. a. Describe reclamation of processing facilities, stockpile areas, and on -site roadways. The processing equipment will be disassembled and removed from the property. The plant and stockpile areas and internal roadways will be graded to stable configurations and seeded with various grasses, wildlife food species and tree seedlings, or covered with crushed stone to prevent erosion and sedimentation. The secondary plant and stockpile areas are likely to be developed for commercial/residential/office future uses. b. Will any on -site roadways be left as part of the reclamation? Yes X No ❑. If yes, identify such roadways on the reclamation map and provide details on permanent road and ditch line stabilization. The paved entrance road, scales entrance and exit roads, and the paved office parking area will remain on site or be incorporated into future commercial/residential/office development projects. Stone surfaced pit perimeter and access roadways will remain for use in future (yet to be determined) recreation opportunities. Any needed additional ditch lines not currently existing will be stabilized with riprap and vegetative linings as necessary. �� APPLICATION FOR A MINING PERMIT 6. 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.) No off -site generated waste shall be disposed of on the mine site without prior written approval from the NC Department of Environmental Quality, Division of Energy, Mineral, and Land Resources and either the Division of Waste Management (DWM) or local governing body. If a disposal permit has been issued by DWM for the site, a copy of said permit must be attached to this application. All temporary and permanent refuse disposal areas must be clearly delineated on the mine map(s) and reclamation map, along with a list of items to be disposed in said areas. Scrap metal, junk machinery, cables, and other such mining generated wastes are currently disposed of off -site in appropriate landfills or recycling facilities. It is anticipated that this practice will continue throughout the future of the operation, and that upon final reclamation, no such materials will remain on site. 7. Describe your plan for revegetation or other surface treatment of the affected areas. This plan must include recommendations for year-round seeding, including the time of seeding and the amount and type of seed, fertilizer, lime and mulch per acre. The recommendations must include general seeding instructions for both permanent and temporary revegetation. Revegetation utilizing only tree plantings is not acceptable. Recommendations can be sought from: a. Authorized representatives of the local Soil and Water Conservation District; b. Authorized representatives of the NC Forest Service, Department of Agriculture and Consumer Services; c. Authorized county representatives of the North Carolina Cooperative Extension Service, specialists and research faculty with the Colleges of Agriculture and Life Sciences and Forest Resources at North Carolina State University; d.

Slopes in unconsolidated material will be graded to a stable slope not to exceed two horizontal to one vertical. Loose rocks, woody material, and other obstructions that would interfere with the establishment of vegetation will be removed and either buried or properly disposed of off -site. Surface runoff will be controlled by use of diversions and terraces to allow discharge through protected outlets. Seed Bed Preparation Lime and fertilizer will be incorporated into the soil to a depth of three to four inches on areas where conventional equipment can be used. On slopes steeper than 2:1, soils will be scarified along the contour for seed and nutrient retention. Lime and fertilizer will be applied according to soil tests for the areas being re -vegetated, generally at a rate of 1,000 lbs. of 10- 10-10 and 2,000 lbs. of lime per acre. Newly seeded areas will be mulched with small grain straw spread evenly over the surface at a rate of 1.5 to 2.0 tons per acre. On steep slope areas not accessible to seeding equipment, seed, nutrients, and mulch will be applied by hand. Re -vegetation Species Seed mixtures typically include some combination, depending on the season, of the following: fescue, rye grain, bahiagrass, Kobe lespedeza, Korean lespedeza, Sericea lespedeza, bicolor lespedeza, white ladino clover, partridge pea, and native warm season grasses. Fall or early spring plantings will utilize 100 lbs. fescue and 50 lbs. rye grain per acre. Late spring plantings may include up to 40 lbs. Kobe/Korean lespedeza per acre where desirable to supplement deer browse. Native warm season grasses will be utilized along with Kobe/Korean lespedeza to enhance feeding and nesting areas for wildlife. Sericea lespedeza will be planted at a rate of 20 to 40 lbs. per acre in combination with fescue when planting draughty soils or steep slopes. Clover will be added to deer browse areas at a rate of 3-5 lbs. per acre in fall or early spring plantings. When using lespedeza species in fall plantings, non -scarified seed will be used. Scarified seed will be used in spring plantings. When using clover in wildlife plantings, inoculated seeds will be used. Loblolly pine and red cedar seedlings will be planted at selected sites to provide visual screens. Shrubs and Mast -bearing hardwoods such as those of the white oak subgenera may also be planted to enhance wildlife habitat. -20- APPLICATION FOR A MINING PERMIT E.

C. Crabtree Creek — Wake Stone Bridge (latitude 35.84127 longitude-78.77225) Wake County, North Carolina Prepared by: Sungate Design Group, PA 905 Jones Franklin Road Raleigh, N. C. 27606 For: Wake Stone Corporation Date: February 10, 2019 NO RISE FOR CRABTREE CREEK — Wake Stone Bridge INTRODUCTION Wake Stone Quarry located next to Umstead State Park in Wake County is proposing to construct a bridge across Crabtree Creek. The proposed will be 100 feet in length with vertical abutments. The low chord of the proposed bridge will be about 10 feet above the 100 Year water surface elevation. Crabtree Creek is a FEMA regulated stream and is part of the Neuse River Basin. The current Effective Study is a Detailed Study and is a re -delineation which indicates that the Effective Flood Study is a Hec-2 model. FEMA is in the process of updating the Wake County FIS. As part of this process, Griffith Branch is being updated using Hec-Ras to analyze the flood elevations. It is Sungate's understanding that for a No Rise the Preliminary Flood Study can be used. Therefore, Sungate Design (SDG) contacted NC Floodplain Mapping (NCFMP) to request the Preliminary Hec- Ras model which we received on 11/07/2019. The Preliminary FIRM map is 3720076600J (dated 03/31/2015). The proposed Wake Stone bridge crossing is located at River Station 106838 in Zone AE. DUPLICATE EFFECTIVE MODEL Ao Yi, PE (NCFMP) sent an email to SDG on 11/07/2019 with the Preliminary Hec-Ras files attached. SDG saved the attached Hec-Ras files on the SDG server. The original Hec-Ras files obtained from NCFMP were created using Hec-Ras v4.1.0 and are in NAVD 88 (vertical datum). The Hec-Ras files obtained from NCFMP were copied and used to create a Duplicate model. A Duplicate Plan was created using the Preliminary Geometry file and Steady Flow file. SDG then ran the Duplicate Plan on Hec-Ras v4.1.0. The water surface elevations matched the information found in the original Preliminary Hec-Ras output from NCFMP. No negative surcharges or surcharges greater than 1-foot were found. CORRECTED EFFECTIVE MODEL The Duplicate Model was saved as the Corrected Model. New cross -sections located at River Station 106793, 106805.8, 106869.8 and 106883 were placed in the model using survey data that was provided by Michael Baker International. Cross -sections 106793 and 106883 are located immediately downstream and upstream of the proposed Wake Stone bridge. Cross -sections 106805.8 and 106869.8 are located at the downstream and upstream face of the proposed bridge. The survey data was also used to update the stream channel for River Stations 106629 and 106911. No changes to roughness coefficients for the existing cross -sections were made. No changes to discharges were made. No changes to the Reach Boundary Conditions were made. Contraction and expansion coefficients of 0.1 and 0.3 were used at the new River Stations 106629 and 106911. SDG then ran the Corrected Model on Hec-Ras A.1.0. No surcharges greater than 1-foot were found. However, negative surcharges were found. The Encroachment Stations at River Station 106911 and 111085 were revised to eliminate these negative surcharges. REVISED MODEL The Corrected Model was saved as the Revised Model. The proposed Wake Stone bridge was placed at River Station 106837.9. No changes to roughness coefficients for the existing cross -sections were made. No changes to discharges were made. No changes to the Reach Boundary Conditions were made. Due to the proposed Wake Stone bridge spanning the floodplain at River Station 106837.9, no changes to the contraction and expansion coefficients were made. SDG then ran the Revised Model on Hec-Ras v4.1.0. No negative surcharges or surcharges greater than 1-foot were found. RESULTS There is no change in the water surface elevations when comparing the Revised and Corrected. The Hec-Ras models and the following Tables included with the No Rise Certification package are in NAVD 88.

Well Construction Records Hydrogeologic Evaluation of the Triangle Quarry Wake County, NC April 7, 2020 1.0 Introduction Wake Stone Corporation (Wake Stone) operates an aggregate mine known as the Triangle Quarry in Wake County, North Carolina. The quarry address is 222 Star Lane, Cary, NC, and the quarry is located near the intersection of Harrison Avenue and US Interstate 40 (Figure 1). The Triangle Quarry has been operated for nearly 40 years, and the existing pit covers an area of approximately 73 acres. The total depth of the existing pit is approximately 400 feet, and Wake Stone has limited accessible mineral resources remaining within the existing mine permit area. Wake Stone plans to expand their quarry operation to 105 acres of land to the west of the existing quarry (Figure 1). Wake Stone is evaluating the property and developing a mine permit application to conduct aggregate mining on the new tract. As a part of the mine permit documents, Wake Stone must evaluate potential impacts on the groundwater system associated with dewatering of the new open -pit mine. Because Crabtree Creek borders the expansion property to the south and east, the groundwater evaluation must also address potential interactions between the proposed mine and surface water flow in Crabtree Creek. Wake Stone contracted Groundwater Management Associates, Inc. (GMA) to provide a hydrogeological evaluation of the existing and proposed quarry sites. The following report presents GMA's evaluation results. 2.0 Hydrogeologic Setting and Mine Observations 2.1 Local Hydrogeology of the Mine Site The Triangle Quarry extracts crystalline metamorphic and metavolcanic rocks for use as a crushed stone aggregate. The site lies within the Raleigh lithotectonic belt of the North Carolina Piedmont Physiographic Province (NCGS, 1985). The lithology at the existing mine site includes Cambrian to Late Proterozoic age biotite gneiss and schist, locally mapped as the Big Lake — Raven Rock Schist, and the Reedy Creek Metagranodiorite (Blake and Clark, 2016). The lithology beneath the proposed mine expansion property, immediately west of the currently active mine, is Cambrian to Late Proterozoic age metavolcanic rock, locally mapped as the Pots Branch Greenstone (Blake and Clark, 2016). Figure 2 illustrates the local geology near the mine site. Rocks exposed in the active quarry pit reveal a prominent foliation that strikes approximately N45E and dips steeply (about 50 degrees) to the northwest. One mafic igneous dike is also exposed in the northern section of the mine. Appendix I includes site photographs of the active mine pit illustrating the prominent foliation of the rocks exposed in the mine. Page 1 Hydrogeologic Evaluation of the Triangle Quarry Wake County, NC April 7, 2020 The open pit mine is a dry mine operation, meaning that water that enters the pit through groundwater seepage and precipitation, and both are removed from the mine via a sump in the bottom of the pit. The current sump elevation is approximately 50 feet below mean sea level (MSL), and the average water level in the sump is approximately -40 feet MSL. Wake Stone typically pumps from the sump about 4 to 11 days per month to maintain a dry pit. Reported withdrawals in 2019 (NCDEQ, 2020), included only 76 days of pumping, with the average withdrawal rate for pumping days being 0.958 million gallons per day (MGD). So, the total annual withdrawal in 2019 from the sump was approximately 73 million gallons per year. Averaging this annual withdrawal to a per -day equivalent for 2019 provides an average daily withdrawal of 0.20 MGD, or about 139 gallons per minute. Water withdrawn from the sump is used for dust suppression and processing of aggregate. Excess water, not needed as make-up water in the closed -loop process water system, is discharged through the north pond according to the operation's NPDES permit. The outfall from the north pond drains into Crabtree Creek northeast of the pit (Figure 1). Flow from the outfall is intermittent. Wake Stone reported 29 days of discharge from the outfall in 2019. Appendix II includes records of pit sump withdrawals reported for 2019. The estimated groundwater recharge to the area of the Triangle Quarry is 400,000 gallons per day per square mile (Heath, 1994). The active mine site covers an area of approximately 0.15 square miles, so the normal groundwater recharge rate within the footprint of the active quarry pit is estimated to be about 60,000 gallons per day. The Raleigh area receives an annual average precipitation of approximately 48 inches of rainfall equivalent (NC Climate Office, 2020). Applying this precipitation rate over the footprint of the active mine gives an estimate of stormwater contribution (approximately 122.35 million gallons per year, or an average of approximately 0.335 MGD) to the pit. Comparing the estimated stormwater flow into the pit with the reported sump withdrawals from 2019, and considering that a significant portion of precipitation returns to the atmosphere via evaporation, it is evident the groundwater flow contribution into the pit from outside the active mine must be very small. Because porosity of typical Piedmont crystalline rocks is 0.01 to 2% (Heath, 1984), the bedrock contains a very small amount of water as storage. Likewise, permeability of Piedmont rocks is low. This condition leads to very small and narrow cones of depression around pumping wells and open pit quarries. Local fractures and fault systems within the Piedmont may exhibit significantly higher permeability than unfractured rock matrix, and when such features occur, drawdown around points of withdrawal (wells or mines) may extend preferentially along these enhanced permeability features for significant distances away from the pumping center. When large local fractures intersect a mine face, these features are readily observed by local wetting of the mine face and obvious local flow into the pit. Page 2 Hydrogeologic Evaluation of the Triangle Quarry Wake County, NC April 7, 2020 The active mine pit at the Triangle Quarry exhibits a remarkably dry mine face. GMA observed the mine on December 10, 2019, and the quarry pit did not indicate local wetting or other indications of significant preferential flow of groundwater into the pit (see Appendix I). We observed one mafic igneous dike cutting across the pit in the northern portion of the mine, but this darker rock did not exhibit wetness or enhanced groundwater seepage into the pit. It was especially notable that the mine face closest to Crabtree Creek along the western and northern portions of the pit exhibited only minimal wetness or groundwater seepage into the pit. These anecdotal data suggest that Crabtree Creek does not lose a significant amount of flow as the creek passes close to the open pit mine. 2.2 Hydrology of Crabtree Creek Crabtree Creek is an urban stream, and the flow characteristics are significantly affected by anthropogenic development, especially in areas upstream of the Triangle Quarry. The local stream channel adjacent to the Triangle Quarry and downstream from the quarry into the Umstead State Park appears to be mostly natural. However, the hydrology of the system feeding this section of Crabtree Creek is not natural. Upstream from the Triangle Quarry are two major alterations in the stream system: Lake Crabtree (an approximately 430-acre manmade impoundment), and the Town of Cary Wastewater Treatment Plant effluent discharge. The Crabtree Lake maintains an average pond elevation of approximately 274 feet above mean sea level (USGS, 1987). Stormwater that falls within the catchment of Crabtree Lake is retained behind the dam, and flows into Crabtree Creek via a spillway below the dam. GMA is unaware of any metering of flows from the Crabtree Lake spillway. The Town of Cary treats municipal wastewater at the North Cary Water Reclamation Facility (WRF) on Old Reedy Creek Road. The WRF is rated for 12 MGD treatment capacity, and the treated wastewater effluent is discharged directly to Crabtree Creek approximately 0.6 miles upstream from the Triangle Quarry location. The timing and volumes of wastewater discharged into Crabtree Creek by the Town of Cary WRF significantly affect the flow characteristics of Crabtree Creek near the Triangle Quarry. According to Paul Ray (Town of Cary) the North Cary WRF discharged 6.18 MGD on January 30, 2020 (personal communication, 3/3/2020). The WRF only report daily totals, so details of timing of wastewater effluent discharges are not available. If discharges from the WRF were continuous and constant, the reported discharge volume from January 30, 2020 would equate to approximately 9.6 cubic feet per second. In addition, Local tributaries that feed Crabtree Creek near the Triangle Quarry are impounded (e.g., Foxcroft Lake and Reedy Creek Lake). These impoundments further alter the timing and volumes of stormwater and groundwater flow into the creek. Page 3 Hydrogeologic Evaluation of the Triangle Quarry Wake County, NC April 7, 2020 Overall flow in Crabtree Creek is dynamic, and significant diurnal patterns of flow volumes are documented by the USGS at their Ebenezer Church Road gaging station (Station ID 0208726005) located approximately 3 miles downstream from the Triangle Quarry (Figure 1). Figure 3 illustrates the diurnal nature of flow dynamics at Crabtree Creek as recorded by the USGS gaging station. Daily fluctuations of flow on the order of 15 to 30 cubic feet per second (CFS) were recorded at the gaging station between January 28, 2020 and January 31, 2020. Superimposed upon the diurnal fluctuations are larger -scale flow events related to local precipitation and stormwater flow into the creek. The dynamic flow characteristics of Crabtree Creek significantly affect the assessment of potential baseflow stream loss from Crabtree Creek in the vicinity of the Triangle Quarry. 3.0 Field Evaluations GMA devised a study scope that entailed office research coupled with field data collection to gain an understanding of the hydrogeologic setting of the site and to evaluate interactions between local flow in Crabtree Creek and groundwater flow conditions on the mining properties. The focus was to characterize the hydrologic system in the context of the existing mine as a proxy for understanding the hydrologic effects of the proposed mine expansion. This characterization included stream flow measurements in Crabtree Creek as well as groundwater level measurements in existing and newly constructed wells. 3.1 Stream Flow Study GMA estimated stream discharge at four sites on Crabtree Creek on January 30, 2020 (Figure 4). These included one upstream location (Station 1), two locations adjacent to the Triangle Quarry (Station 2 and Station 3) and one location approximately 0.5 mile downstream from the quarry (State Park Station). Stream discharge (Q) is the rate of flow or the volume of water that passes through a channel cross section in a specific period of time. GMA used the velocity -area technique to calculate stream discharge at each monitoring station. For this technique, discharge was calculated as the product of surface water velocity and cross -sectional area of the water in the channel. Methods employed by GMA for this project followed guidance from the USGS and the National Nonpoint Source Monitoring Program (Carter and Davidian, 1989; Meals and Dressing, 2008). GMA selected stream discharge measurement locations that were reasonably straight and free of large rocks or obstructions. At each station, GMA waded into the stream and measured the width of the stream perpendicular to flow using an open reel measuring tape. We divided the stream width into segments so that each segment did not represent more than 10% of the total streamflow, and we measured the depth of each segment using a stadia rod. Page 4 Hydrogeologic Evaluation of the Triangle Quarry Wake County, NC April 7, 2020 GMA also measured water velocity within each segment using a Global Water FP211 Flow Probe velocity meter. This meter has a minimum reporting limit of 0.1 ft/second. At all stations, the stream was shallow and wadeable. Therefore, GMA used the one -point method to measure water velocity within each segment. For the one -point method, velocity was measured at 0.6 the total depth for that segment. Water velocity is not uniform throughout the water column and is influence by factors such as friction with the channel bed and overall channel geometry. Previous studies have shown that velocity at a position 0.6 the distance from the water surface to the stream bed is, however, a good approximation for average water velocity within a channel section (Leopold et al. 1964). According to Harmel, et al. (2006), the calculated cumulative probable uncertainty for the standard streamflow measurement methods is f6% for average conditions. For velocity measurements collected from Crabtree Creek, GMA recorded the average velocity from 15 seconds of monitoring at 0.6 times the stream depth. GMA calculated the stream discharge for each segment as the area of each segment (the product of segment width and segment depth) multiplied by the velocity measured in that segment. We then summed the discharges of each individual segment to obtain to an estimate of total discharge for the stream at each location. Table 1 presents the estimated stream flow volumes from each monitoring station. These flow estimations are instantaneous flows at the time of data collection, and the units are reported as cubic feet per second (CFS). Figures 5 through 8 illustrate the channel profiles at each measurement station. 3.2 Groundwater Evaluation GMA worked with Wake Stone to evaluate the groundwater conditions beneath the expansion property. Wake Stone drilled multiple core holes on the expansion property to evaluate the lithology and rock quality for mine planning. As a part of this core -drilling program, five holes were constructed as monitoring wells with permanent well casings. Figure 9 illustrates the monitoring well locations. Appendix V includes the well construction records for the five new monitoring wells. Wake Stone arranged surveying of the locations and reference point elevations for the wells. Table 2 presents the location and reference point elevation data associated with the wells. On February 19, 2020, GMA collected static water levels from the five monitoring wells on the expansion property. In addition, we measured water levels in an uncased core hole (Core N) located on the pit perimeter road between the quarry pit and Crabtree Creek. Water -level measurements were collected using an electronic water -level meter, and values were measured to the nearest 0.01 feet. Appendix 1 includes photographs of example monitoring wells and Page 5 Hydrogeologic Evaluation of the Triangle Quarry Wake County, NC April 7, 2020 water level measurement methods. Table 2 presents the water -level measurements. GMA used the reference point elevations from each well and core hole to calculate the groundwater elevations from each station. In addition, we considered the estimated elevations (from LIDAR data) of Crabtree Creek adjacent to the Triangle Quarry pit. We considered the assigned creek elevations as groundwater base levels along the stream. Wake Stone reported to GMA the sump water elevation (40 feet below mean sea level) from the base of the quarry pit. These groundwater and surface -water elevation values were used to produce a contour map depicting the current interpreted groundwater elevations beneath the expansion property (Figure 10). Subsequent to the February 19, 2020 monitoring event, GMA recognized that additional wells exist on the active mine property that could be accessed for supplemental water -level monitoring. GMA determined that these supplemental well locations were important for depicting the equipotential surface surrounding the active quarry pit. On April 2, 2020, a GMA hydrogeologist visited the Triangle Quarry site to collect additional static water levels. This monitoring event incorporated data from two additional wells, the "Shop Well", and the "QC Lab Well" (Figure 9). Wake Stone provided survey data of the locations and reference point elevations for the two additional well locations. Figure 11 presents the equipotential contour map of water levels collected from April 2, 2020. 4.0 Discussion and Conclusions 4.1 Crabtree Creek Flow Monitoring Stream flow monitoring of Crabtree Creek demonstrates a significant stream flow in the vicinity of the Triangle Quarry pit. The flow measured from Stations 1 through 3 ranged from 49.7 CFS to 50.3 CFS. These values are essentially the same flow, when considering the ±6% accuracy of the methods of measurement. The stream gaging data provide no evidence of measurable stream losses from Crabtree Creek in close proximity to the active quarry pit. The stream flow measurements from Stations 1 through 3 do indicate a modest increase in flow as the monitoring progressed to Station 3. However, Station 3 was located downstream of the effluent from the settling ponds that handle water withdrawn from the quarry sump. GMA separately measured the flow from the settling pond (called Tributary from Pond in Table 1), and the increased flow documented at Station 3 can be attributed, at least in part, to the flow into Crabtree Creek from the Tributary Pond. The monitoring station located approximately 0.5 mile downstream from the quarry (State Park Station) revealed an anomalously lower value of flow (45.3 CFS) when compared to flow measurements from Stations 1-3. GMA recognizes several likely explanations for this anomalously lower flow measurement: Page 6 Hydrogeologic Evaluation of the Triangle Quarry Wake County, NC April 7, 2020 • Flow measurements at the State Park Station were collected 2 hours after the next closest upstream station (Station 3). As is shown in Figure 3, stream flow in Crabtree Creek can vary significantly over short spans of time. These variations in flow are attributable, in part, to variations in discharge from the North Cary Water Reclamation Facility. Unfortunately, the Town of Cary only accounts for daily flow volumes discharged from the facility, so details of discharge variability from the WRF are not available to help understand the streamflow monitoring results from the State Park Station. • The State Park Station is located downstream from an historic dam structure across the creek. This old mill dam partially impounds flow in the creek, and the flows measured at the location selected for the State Park Station may be affected by proximity to the dam. • The State Park Station also included a large sand and gravel bar along the shoreline. This permeable section of sediment deposition may locally absorb a small percentage of stream flow as ephemeral groundwater flow along the channel margin. This type of ephemeral groundwater flow within stream channel deposits would not be accounted for by the stream gaging measurements. Although GMA measured a reduced stream discharge at the State Park Station, the reduced flow documented at that location is not attributable to water withdrawals from the active quarry pit. The State Park Station is far removed from the limited area of drawdown around the active quarry pit, as discussed below. 4.2 Groundwater Evaluation Discussion GMA produced contour maps of pertinent water -level data from monitoring wells and the elevation of the active quarry sump. These data were contoured for both the active mine area and the surrounding area, with special emphasis on the proposed new mine tract. GMA recognizes that contours of the equipotential surface from the limited data within the active mine, as shown in Figures 10 and 11, are theoretical contours, because the contoured equipotential surface is above the elevation of the bottom surface of portions of the active mine. Based on these contoured head values, and our previous discussion of recharge to, and discharge from, the active quarry, GMA concludes the following: • The cone of depression associated with active mining is very small; • The anticipated cone of depression associated with mining of the new tract is also expected to be small because similar low -permeability igneous/metamorphic rocks characterize the new tract.

Box 190 6821 Knightdale Blvd. Knightdale, N.C. 27545 919/266-1100 Fax: 919/266-1149 Please find attached our application for the installation of 5 Monitoring Wells on our Triangle Quarry expansion project. The purpose of the wells is to establish the currently existing crystalline rock aquifer groundwater surface elevation. The wells are to be located on lease -held property owned by Raleigh Durham International Airport (105 acre "Oddfellows Tract") north of 1-40, east of Old Reedy Creek Road and west of Crabtree Creek adjacent our currently operating Triangle Quarry. As detailed in the application materials, these proposed wells will be constructed by installing 4" ID galvanized casing through the overburden (soil and decomposed bedrock) into sound/unweathered bedrock. The casings will be grouted in place from the sound bedrock surface to land surface utilizing neat cement grout place by tremie pipe. The open borehole portion of each well will be advanced to final depth via diamond core drilling for rock quality assessment. Pursuant to the "Additional Information" section of the application form, there are no known sources of potential groundwater contamination located on the subject property. A single family residential well and septic system (Dunn residence) is located at the northwest corner of the property. This well and septic system is located within 500' of two of the proposed monitoring wells. Information on this domestic well and septic system has been obtained from Wake County Environmental Services and is appended to the well construction application for your review. Mr. Brion Byers December 30, 2019 Page 2 We anticipate mobilization of the well drilling contractor (Carolina Soil Investigations, LLC) on or about January 13, 2020. As such, we would appreciate your assistance in processing the well construction permit application in as timely a manner as possible. Thank you for your assistance in this matter.

SAW-2019-01286 County: Wake U.S.G.S. Quad: NC- Cary NOTIFICATION OF JURISDICTIONAL DETERMINATION Requestor: Soil & Environmental Consultants PA Attn: Bob Zarzecki Address: 8412 Falls of Neuse Rd. Suite 104 Raleigh, NC 27615 Size (acres) —105 Nearest Town Cary Nearest Waterway Crabtree Creek River Basin Neuse USGS HUC 03020201 Coordinates 35.841639,-78.774819 Location description: The project area is located on the north side of I-40 and the east side of Old Reedy Creek Road in Cary, Wake County, North Carolina. PIN: 0767324317. The project area is limited to the area within the line labeled "PL" on the attached survey titled "Plat of Waters of the US Survey for Wake Stone Corporation." Indicate Which of the Following Apply: A. Preliminary Determination ❑ There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters, including wetlands have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. The approximate boundaries of these waters are shown on the enclosed delineation map dated DATE. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district for further instruction. ❑ There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the waters, including wetlands have not been properly delineated, this preliminary jurisdiction determination may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands at the project area, which is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters, including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. B. Approved Determination ❑ There are Navigable Waters of the United States within the above described project area/property subject to the permit requirements of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ® There are waters, including wetlandson the above described project area/property subject to the permit requirements of Section 404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ We recommend you have the waters, including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. ❑ The waters, including wetlands on your project area/property have been delineated and the delineation has been verified by the Corps. The approximate boundaries of these waters are shown on the enclosed delineation map dated DATE. We strongly suggest you have this delineation surveyed. Upon completion, this survey should be reviewed and verified by the Corps. Once verified, this survey will provide an accurate depiction of all areas subject to CWA jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied upon for a period not to exceed five years. SAW-2019-01286 ® The waters, including wetlands have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official identified below on 1/15/2020. Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ There are no waters of the U.S., to include wetlands, present on the above described project area/property which are subject to the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (LAMA). You should contact the Division of Coastal Management in Morehead City, NC, at (252) 808-2808 to determine their requirements. Placement of dredged or fill material within waters of the US, including wetlands, without a Department of the Army permit may constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material, construction or placement of structures, or work within navigable waters of the United States without a Department of the Army permit may constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403). If you have any questions regarding this determination and/or the Corps regulatory program, please contact David E. Bailey at (919) 554-4884 X 30 or David.E.Bailev2 Ausace.army.mil. C. Basis For Determination: See the Approved Jurisdictional Determination forms dated 01/15/2020. D. Remarks: None. E. Attention USDA Program Participants This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the particular site identified in this request. The delineation/determination may not be valid for the wetland conservation provisions of the Food Security Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation in USDA programs, you should request a certified wetland determination from the local office of the Natural Resources Conservation Service, prior to starting work.

Explain: SECTION HI: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). s Supporting documentation is presented in Section III.F. -2- The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.L; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent': B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section IILC below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs.

CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW?

CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1.

For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands.

Explain: SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs Boxes checked below shall be supported by completing the appropriate sections in Section III below. s For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). s Supporting documentation is presented in Section III.F. -2- The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent': B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 92,971 acres Drainage area: 79 acres Average annual rainfall: 46 inches Average annual snowfall: 4 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through 9 tributaries before entering TNW. Project waters are 20-25 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 10-15 aerial (straight) miles from TNW. Project waters are 1 (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNWS: Stream 1 (UT to Crabtree Creek; seasonal RPW) to Crabtree Creek (RPW) to Neuse Rive (TNW) Tributary stream order, if known: 1st 'Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. -3- (b) General Tributary Characteristics (check all that apply): Tributary is: ❑ Natural ® Artificial (man-made).

Explain: 'A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: -5- Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) Y 0.143 Summarize overall biological, chemical and physical functions being performed: This wetland and others in similar landscape positions receive preciptation-derived- and ground- water from surrounding land and occasional flooding from abutting impoundment, retain and slowly release water, physically trap and retain sediment, allow biogeochemical anaerobic processes (i.e. denitrification) to occur to improve water quality, and serve as groundwater recharge areas. These wetlands serve as year-round cover and food source for a variety of typical wildland-urban interface wildlife species. C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs.

Explain: SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs Boxes checked below shall be supported by completing the appropriate sections in Section III below. s For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). s Supporting documentation is presented in Section III.F. -2- The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.l.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1.

C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section I1I.1): Wetland 2 is hydrologically connected to Crabtree Creek (perennial RPW) as an abutting wetland, and Wetland 1 is hydrologically connected to Crabtree Creek given its position within a floodplain subject to occasional flooding. Such wetlands have the capability to capture overland runnoff and floodwaters, retain and slowly release water and organic carbon downstream, physically trap and retain sediment, and allow biogeochemical anaerobic processes (i.e. denitrification) to occur to improve water quality. These actions limit sediment and nutrient input into Crabtree Creek, designated by the NCDEQ as a Nutrient Sensitive Water, which flows directly to the Neuse River within 25 river miles. Such wetlands also serve as breeding habitat for amphibian species, and provide year-round cover, food source, and movement corridors for a variety of typical wildland-urban interface wildlife species. As such, Wetlands 1 and 2, and -6- similarly situated wetlands, affect the chemical, physical, and biological integrity of, and have a significant nexus with, the Neuse River, a TNW. D.

Stream, wetland, or pond impacts are still subject to applicable water quality standards and permitting requirements. Explanation: The stream(s)/pond(s) listed above has been located on the most recent published NRCS Soil Survey of Wake County, North Carolina and/or the most recent copy of the USGS Topographic map at a 1: 24,000 scale. Each feature that is checked "Not Subject" has been determined to not be an intermittent stream, perennial stream, a pond connected to a stream feature, or the feature is determined not to be present. Stream features that are checked "Subject" have been located on the property and possess characteristics that qualify them to be subject to the buffer rules. There may be other streams located on the property that are not depicted on the maps referenced above and are therefore not subject to the buffer rules. However, if the stream features are present on the tract they are subject to all other applicable North Carolina stream standards and permitting requirements as outlined in 15A NCAC 02B, and may be considered jurisdictional according to the US Army Corps of Engineers.

Please explain and detail according to "help file" instructions.* Previous Nationwide Permit verifications were obtained for the Triangle Quarry in 1991, but known for the area of the proposed bridge over Crabtree Creek and no previous Neuse Buffer Authorization Certificates (as the buffer rules did not exist in 1991). The proposed mining permit expansion project and associated bridge will avoid all jurisdictional WOTUS for the foreseable future. The future pit on the RDU Airport property may eventually require impacts to WOTUS and Neuse Buffers some time in the future depending on market demands. Any such impacts would be requested from the USACE and DWR at that time. 7. Future Project Plans 7a. Is this project a phased project?* r Yes r No 7b. If yes, explain* The new pit on the RDU Airport lease property is designed to avoid all impacts to WoTUS and Neuse Buffers. However, any additional expansion of the pit in the future Will most likely require impacts to WoTUS and/or Neuse Buffers. This will be years from now and dependent on market demands. Wake Stone Corporation will request and obtain any necessary approvals from the USACE and DWR prior to conducting any such impacts. A C. Proposed Impacts Inventory C.

Impact Justification and Mitigation D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project.* Wake Stone Corporation hired S&EC, PA to delineate and verify all jurisdictional wetlands, streams, other Waters of the US (WoTUS) and Neuse Buffers on both the RDU Airport lease property and the existing Triangle Quarry site. Wake Stone Corporation then used this information to design the pit on the RDU Airport lease property to avoid all impacts to WoTUS and Neuse Buffers. They then designed the bridge across Crabtree Creek to avoid impacts to WoTUS and to cross the creek and Neuse Buffers at a perpendicular angle to minimize impacts to the Neuse Buffers. Future impacts to the WoTUS and Neuse Buffers will be necessary for expansion of the pit on the RDU Airport lease property, but these will be years from now and dependent on market demands. As such these resources can remain in place until then and of course pending any necessary approvals from both the USACE and DWR. See attached Wake Stone Corp E&SC Plan" 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. * Wake Stone Corporation is in the process obtaining an updated Mining Permit for the Triangle Quarry to include the RDU Airport lease land and bridge. This Mining Permit will include all required BMP measures to protect downstream water quality. See attached Wake Stone Corp E&SC Plan & Narrative' E. Diffuse Flow Plan E.

Results from this study should be a reliable indicator of what to expect when blasting on the adjacent RDU Odd Fellows tract. The modified US Bureau of Mines (USBM) RI 8507 Alternative Blasting Level Criteria graph (shown below) was used as the allowable vibration limit for this investigation. This is the same blasting vibration limit currently in place for all North Carolina quarry NCDEQ mining permits. 10.1 �r m w `c 34 a y �0 L7 C e9 1.0 � a_s 0.7 M 0A � 4,2 �x 0.7 2 �nfgat i 4.75 inrsrt F H 1 i i 1 3 10 20 ]d Blast Vibration frequency, Hz 10.0 2.0 1_5 1.0 0.g 0.7 0.5 0.5 0.4 0.3 02 Figure I Altemative blaOng level criteria (Source modfrred from figure 8-1. Bureau of Mines R? 850 The USBM graph above represents ground vibration data in two axes. The vertical axis represents Peak Particle Velocity (PPV), which is the peak speed the ground moves during a blast event and is measured in inches per second of ground movement. The horizontal axis represents Frequency (Hz), which is the rate at which the vibration wave from a blast travels through the ground, and is measured in cycles per second. Allowable PPV on the modified USBM RI 8507 graph varies with the frequency of the ground vibration. So long as measured vibration remains below the limits shown on the USBM graph referenced above, no damage to structures will occur. DYNG Dyno Nobel Groundbreaking Performance - 2 It should be noted that humans are sensitive to ground vibration and can detect levels of vibration as low as 0.05 in./sec. or lower. Just because vibration can be detected by a human does not mean damage is taking place on a structure. Air overpressure represents the energy from a production blast that is propagated as a pressure wave through the air, and is measured in linear decibels (dBL). This pressure is measured with a calibrated microphone. A level of 133 dBL Peak Air Pressure using a 2.0 Hz flat -response microphone was used as the allowable limit for this investigation. This is the same air overpressure limit currently in place for all North Carolina quarry NCDEQ mining permits. It should be noted that humans are sensitive to air overpressure and can detect levels of air overpressure (heard as noise) at very low levels. Just because air overpressure can be detected by a human does not mean damage is taking place on a structure. Below are some typical levels of air overpressure for reference: 0 dBL — Threshold of hearing 20 dBL — Whisper 40 dBL — Hospital room 65 dBL — Ordinary conversation 70 dBL — Vacuum cleaner 80 dBL — Alarm clock 90 dBL — Hair dryer 110 dBL — Car horn 120 dBL — Overpressure produced by 20 mph wind 133 dBL — Allowable limit of NCDEQ mining permits 150 dBL — Poorly mounted windows break 170 dBL — Most windows break 180 dBL — Structural damage occurs DynoConsult, a division of Dyno Nobel, started the investigative process by performing a vibration regression. The purpose of a vibration regression is to develop an equation that will predict the PPV of a production blast at varying distances from the blast site in a given geology. Data was collected with seismographs through a series of production blasts conducted at Wake Stone's Triangle Quarry and provided to DynoConsult. The graph of the vibration regression is shown below: DYNO. Dyno Nobel Groundbreaking Performance- 3 Wake Stone - Triangle Quarry Regression The regression graph above represents data in two axes. The vertical axis is Peak Particle Velocity (PPV). The horizontal axis is Scaled Distance (S.D.), which is a function of distance from the blast site and the maximum pounds of explosives per delay period for the blast. The 95% regression line represents a 95% confidence level that at a given Scaled Distance value, the recorded maximum PPV will be below this line. Through the data collected by the seismographs for these blasts, the factors of the expected ground vibration for this geology were developed to show the slope of the 95% predictive equation to be -1.426 and the intercept of the 95% predictive equation be 70.435. The equations for the mean and 95% regression lines are given as: PPVmean = 33.942(S.D.)-1.426 PPV95% = 70.435(S.D.)-1.426 The full regression analysis and supporting blast reports and seismograph readings are available upon NCDEQ request. DYNO. Dyno Nobel Groundbreaking Performance - The table below shows some of the seismograph data collected from actual production blasts at the Triangle Quarry used to develop the equations above. The data in the table shows only the blasts that were monitored with a seismograph at a distance between 400 feet and 500 feet from the blast site. All were within the allowable limits for vibration: Blast # Distance from Blast ft. L Channel PPV in./sec. L Channel Frequency (Hz.) T Channel PPV (in./sec.) T Channel Frequency (Hz.)

With the data produced from the signature hole, a waveform analysis was used to simulate varying blast designs over a period of eleven additional blasts, T-8 through T-18. During these eleven blasts, all ground vibration results were well within allowable limits at a distance of 500 feet from the blast site. While ground vibration continued to be within allowable limits for these eleven additional blasts at a distance of 500' from the blast site, the air overpressure for the first four blasts (T-8 through T-11) was close to or slightly above allowable limits. Changes in loading practices were then implemented to reduce the air overpressure on blasts T-12 through T-16. This data is represented in the table below (all seismograph readings taken at a distance of 500 feet from the blast site): DYNO.

Ground vibration remained well in compliance. After five consecutive blasts demonstrating air overpressure could be controlled to remain within allowable limits, loading returned to previous practices for blasts T-17 and T-18 to confirm the changes made on blasts T-12 through T-16 were effective in reducing air overpressure. DYNO, Dyno Nobel Groundbreaking Performance - In summary, based on the vibration regression developed and the data collected during this investigation, there is full confidence that compliance within NCDEQ allowable ground vibration and air overpressure limits can be maintained for structures as close as 500 feet from a given blast site in the Triangle quarry and in similar geology such as occurs on the RDU Odd Fellows tract.
