Specific plans and location information are described below and shown on the attached plans. This Public Notice and all attached plans are also available on the Wilmington District Web Site at vNww.,a??.us?rcc.army.mil???ctlands Applicant: AGENT (if applicable): Authority Mr. Steve Holland Shelter Creek Quarry, LLC 8315 NC Highway 53 East 3 Burgaw, North Carolina 28425 L Mr. James Taylor 0C 1 1 208 Southern Environmental Group, Inc. v?ENR WAfER QJAUh 5315 S. College Road, Suite E Wilmington, North Carolina 28412 The Corps will evaluate this application and a decide whether to issue, conditionally issue, or deny the proposed work pursuant to applicable procedures of Section 404 of the Clean Water Act (CWA). Location The project area is adjacent to Holly Shelter Creek and is located on the southern side of N.C. Highway 53, south of Angola Bay, west of Old Maple Hill Road, northeast of Burgaw, Pender County, North Carolina. (latitude 34.63206and longitude -77.74502). The wetlands on the property are adjacent to Holly Shelter Creek, which is a traditional navigable water of the U.S. Existing Site Conditions The project area is approximately 375 acres and consists mainly of managed game land, wooded wetlands and the first phase of the limestone mining operation. According to the Pender County Soil Survey, the property consists mainly of Muckalee loam, Woodington fine sandy loam, Pactolus fine sand and Foreston loamy fine sand. The entire project area is located within the 100 year flood plain of Holly Shelter Creek. Most of the uplands in the project area are managed for game species like white-tailed deer, wild turkey, rabbits and bob white quail. There are also two impoundments on the property that provide habitat for ducks and geese. There is 72 acres of mostly uplands located in the northern half of the property that is in the process of being mined or being prepared for the purpose of mining. A ditch is located along the southern half of the western property boundary. Water is pumped into this ditch from the mining pits to hydrate the wetlands located off the property. A nationwide permit 39 (Action ID No. 200400613) was utilized to impact 0.102 acres of wetlands for the area currently being mined. There are approximately 166 acres of wetlands on the property. There are five isolated wetlands that total 3.14 acres in size. These wetlands are labeled as BB, CC, H, J, and K on the map labeled as attachment 1. Wetland BB is an herbaceous wetland that is currently being mowed and was used in agricultural production several years ago. The other isolated wetlands are forested and consist mainly of loblolly pine (Pinus taeda), red maple (Acer rubrum), wax myrtle (Morella cerifera) and fetterbush (Lyonia lucida). There are approximately 162 acres of DA jurisdictional wetlands that are adjacent to Holly Shelter Creek. These wetlands are mostly forested, with the exception of B, F, and G. Wetlands A, C, and D are seasonally saturated and can be described as pocosin and wet flat wetland types consisting mainly of loblolly pine (Pinus taeda), red maple (Acer rubrum), wax myrtle (Morella cerifera) and fetterbush (Lyonia lucida). Wetland EE and DD are seasonally inundated and can be described as non-riverine swamp forests consisting mainly of bald cypress (Taxodium distichum) and sweet gum (Liquidambar styraciflua). The remainder of the jurisdictional wetlands are semi-permanently inundated and can be described as bottomland hardwood and riverine swamp forest consisting mainly of (Taxodium distichum), swamp black gum (nyssa biflora), and water oak (Quercus nigra). There are also 2 man-made waterfowl impoundments that are labeled M, HH, and KK. The surrounding land use currently consists of NC Highway 53 and Angola Bay to the north and Holly Shelter Creek and wooded undeveloped land to the south, east and west of the property. Applicant's Stated Purpose To expand an existing limestone quarry. (See Attachment C) 2 Version 12/12/05 Project Description The applicant proposes to create, cultivate and maintain a limestone rock quarry, which would involve mechanized land clearing, excavation of soil and the extraction of limestone from 179.5 acres of land, including 44.84 acres of DA jurisdictional wetlands. Some of the overburden would be used to construct berms and roadways. Phase 1 is currently in the process of being mined and is anticipated to be mined out in 12-14 years. Phase 1 was authorized in 2006 (Action ID# 200400613) and the mining operation opened in 2007. The entire project would be mined in 4 phases, referenced as Phase IA, IB, IIA and IIB (as shown on the attached map labeled Attachment B). The first phase (Phase IA) is located west of the entrance road and the existing operation and would impact 17.7 acres of wetlands. A ditch would be excavated along the western property boundary and would be used to convey surface water to hydrate the wetlands located off-site. The second phase of the mining operation would be Phase IIA, which is located to the east of the entrance road and the existing operation. This phase would impact 11.4 acres of jurisdictional wetlands. The third phase of the mining operation would be Phase IB, which would be located south of Phase IA in the southwestern portion of the property. This phase would impact 2.84 acres of jurisdictional wetlands. Phase IIB would be the final section of the quarry and would be located to the south of Phase IIA in the southeastern portion of the property. This phase would impact 12.9 acres of jurisdictional wetlands. The pump water collection system has been developed as part of Phase I and is currently in operation. Water from the pits would be pumped to a horseshoe pond. Water from the horseshoe pond would then be pumped to a level spreader pond that would discharge into the large wetland area located in the south-central part of the project area. (Refer to Attachment E). As required by the mining permit for the existing operation, ground-water monitoring wells have been installed on-site and off-site. Refer to Attachment D for the locations of the monitoring wells. The applicant plans to avoid impacts to Holly Shelter Creek and 119 acres of bottomland hardwood/riverine swamp forest wetlands located in the south-central part of the project area. To mitigate the wetland impacts, the applicant plans to preserve the 119 acres of wetlands and create wetlands in the project area as part of the mine reclamation process. Version 12/12/05 A more detailed project description and alternatives analysis has been provided and is described in Attachment C. Other Required Authorizations This notice and all applicable application materials are being forwarded to the appropriate State agencies for review. The Corps will generally not make a final permit decision until the North Carolina Division of Water Quality (NCDWQ) issues, denies, or waives State certification required by Section 401 of the Clean Water Act (PL 92-500). The receipt of the application and this public notice combined with appropriate application fee at the North Carolina Division of Water Quality central office in Raleigh will constitute initial receipt of an application for a 401 Water Quality Certification. A waiver will be deemed to occur if the NCDWQ fails to act on this request for certification within sixty days of the date of the receipt of this notice in the NCDWQ Central Office.

Location The proposed project is located on an approximately 397.7-acre tract owned by Yellow Lab Farms, LLC. The site is located approximately 11 miles east northeast of Burgaw and 4 miles west southwest of Maple Hill. -- 1: Location of Site within Pender County. The project site is located south of and adjacent to NC Highway 53 East, and has an address of 12121 NC Highway 53 East, Pender County, North Carolina (34.6354°N, -77.7509°W). The southeastern project boundary is along or close to Holly Shelter Creek, which eventually flows into the Atlantic Ocean after passing through the Northeast Cape Fear River and the Cape Fear River. There are approximately 184 acres of wetlands within the project area. A small area along Holly Shelter Creek and the creek itself were not included in the delineation, as they are outside of the proposed project area, and no impacts (present or future) are anticipated in these areas. The property to the east and north of NC 53 is owned, and managed, by the North J jhelter Qreek Quarry IF IV? 71 5r 6i Carolina Wildlife Resources Commission (WRC). These areas were previously managed for timber production and are currently maintained as public game lands. To the west of the Existing Conditions North Carolina's Lower Coastal Plain population is growing rapidly along the Atlantic Ocean, and along major north/south transportation routes. Interior portions of this region are predominantly agricultural/silvicultural, and population growth is slower in these areas. Pender County is the 5th largest county in North Carolina, with 871 square miles. In 2000, approximately 75% of the county was forested and 10% was cropland. The population of Pender County was 48,630 people according to the 2006 census estimate. This represents a 18.4% increase over that reported in the 2000 Census. While there are fast growing coastal communities in Pender County between US 17 and the Atlantic Ocean, most of the County west of US 17 is not currently under strong development pressure. Although Burgaw and small communities are experiencing growth, the communities on or near the ocean and navigable waterways appear to be more desirable places for people to settle. Northeastern Pender County is predominantly rural with single family homes dotting areas 9 Shelter Crec? Quarry IF [41271 5F 6i surrounding State-owned Game Lands, small farms, hunting clubs, and a few commercial properties. The proposed project site is located approximately 11.5 miles east northeast of the town of Burgaw and 4.2 miles west of the Maple Hill Community. The proposed project is located in the Lower Coastal Plain of southeastern North Carolina and in the Carolina Flatwoods section of the Middle Atlantic Coastal Plain Ecoregion. The North Carolina Flatwoods Ecoregion is characterized as a nearly-level area where Carolina bays and pocosins are abundant. Pine flatwoods, pine savannas, freshwater marshes, and pond pine woodlands have been largely replaced by siviculture. Loblolly pine plantations are found throughout the area, and the subject property was used for silviculture when purchased by the current owner. There are six developed parcels located within 2 miles of the subject tract, and only one structure within 1 mile of the proposed project. Based on an aerial review and local visits near the six, two appear to be businesses and four appear to be single family residences. `5kcIter CrecL Ouarr? IP 151271 5 r-6 i 4: Ecoregions Map of Southeastern North Carolina. (I he project is located in the Carolina t latwooas area) Ecological issues in this region are population growth and those issues associated with agricultural and silvicultural uses. Agricultural uses may include incidental discharge into local waterways from animal production, the use of chemical fertilizers and pesticides, and the movement of sediments from agricultural fields into tributaries, all of which may contribute to the degradation of water quality. Ditches, the purpose of which is to drain wetlands, have been constructed in the area for many years, to assist with converting land to productive agricultural and silvicultural uses. Roads, which provide access to these areas, have been maintained over time. Aerial photographs of the WRC properties to the east and north of the proposed site contain a network of drainage ditches and roads used to provide public and private access to these areas. Most of the uplands found within the subject tract are managed for game species. The exception is the front 72 acres, which are either in the process of being mined or are being prepared for the purpose of mining. The managed areas include fields (for foraging and habitat), edges (for escape cover), and an impoundment. Vegetative species, which have been planted in the fields, fv Shelter CreeL Quarry II [6/27) 5r 6i are those utilized by White-tailed deer (Odocoileus virginiana), wild turkey (Meleagris gallopavo), rabbits (Sylvilagus spp.), and bob white quail (Colinus virginianus). The impoundment, which was constructed in uplands, provides habitat for ducks and Canadian geese (Branta canadensis). Nesting boxes were installed to provide a safe haven for wood ducks (Aix sponsa) to lay their eggs. The initial mining efforts are located on the northern half of the subject property. Impacts which have occurred in this area include 0.102 acre of wetland impacts to man made channels, permitted under a Nation-wide permit 39 issued on 10 June 2006 (Action ID# 200400613). (Attachment 1) Wetlands surrounding the initial pit, both on- and off-site, are being monitored for impacts that may be associated with the mining effort. The Applicant's site plan was designed to prevent and/or mitigate for impacts to on-site and off-site wetlands, located adjacent to or near the mine. Wetland Systems Wetlands located within the proposed project include four types: wet flat; pocosin; bottomland hardwood forest: and swamp forest. Figure 5: Aerial of Location of Wetiana 1 ypes un-sue. Shelter Creek Quarry IF [7127] 1 5F-61 Wet Flat Wet flats are wetlands located on relatively level areas on interstream divides in the Sandhills and within the Coastal Plain. These areas are seasonally saturated or inundated by a high or perched water table, but the water table can be more than three feet below the surface during the summer months. The wet flat located on-site is classified as a loblolly pine subtype, and the dominant tree species include loblolly pine (Pinus taeda), red maple (Acer rubrum), and sweetgum (Liquidambar styraciflua). Shrubs found on-site included fetterbush (Lyonia lucida), ink berry (Ilex glabra), and sweet pepperbush (Clethra alnifolia). Laurel-leaf greenbriar (Smilax laurifolia) occupies the vine stratum. The soils were characterized as a sand with high organic content in the surface and were mapped in the Pender County Soil Survey as'Muckalee loam (US Department of Agriculture - Soil Survey, Pender County, North Carolina). This soil series is included on both the National List of Hydric Soils, and the Hydric Soils List of North Carolina. The primary functions provided by loblolly pine wet flats are flood water retention and habitat. This wetland "stores" rainfall, due to a lack of topography, and allows stormwater to slowly infiltrate the soils, eventually reaching groundwater, streams, and/or ponds. While loblolly pine wet flats do not typically include habitat for rare species, they are valuable as habitat for other species, in that they provide resting and foraging areas for mammals, including: white-tailed deer, rabbits, black bear (Urns americanus), gray fox (Urcyon cinereoargenteus), red fox (Vulpes vulpes), raccoon (Procyon lotor), opossum (Didelphus virginiana), and gray squirrel (Sciurus carolinensis). Avian species that may utilize this type of system include: wild turkey, and an array of song birds such as the pine warbler (Dendroica pinus,) and Carolina wren (Thryothorus ludovicianus). Reptiles seeking shelter from larger species, and searching for prey, may include: copperheads (Agkistrodon contortrix), rat snakes (Elphae obsoleta), and box turtles (Terrapene carolina). Pocosin Pocosins are similar to wet flats, but are characterized by extremely dense, nearly impenetrable thickets of shrubs and vines. There are two subtypes of the pocosin found in southeastern North Carolina, short and tall. The type found on-site is the tall pocosin subtype, characterized by /1 Shelter CreeL Quarry IF 18/271 5E-Gi vegetation of normal height and organic layers of one foot or less. Pocosins are typically found on poorly-drained interstream divides and depressions, are seasonally saturated or inundated, and have a thick organic surface over mineral soils. The dominant plant species by stratum include pond pine (Pinus serotina), sweet bay (Magnolia virginiana), red bay (Persea borbonia), and loblolly pine in the canopy; fetter bush, gall berry (Ilex coreacea), sweet pepperbush, and blueberries (Vaccinium spp.) in the shrub layer; and laurel-leaf greenbriar in the vine stratum. Mineral soils (sandy loam) overlain with thick organic material are found in this area. The Pender County Soil Survey describes this soil series as Muckalee loam, a hydric soil per the National Hydric Soil List and on the Hydric Soils of North Carolina List. Pocosins function to provide water storage and wildlife habitat by providing excellent escape cover and an extensive berry crop. Mammals utilizing this system could include black bear, bobcats (Felis rufus), white-tail deer, red fox, gray fox, eastern gray squirrel, and many other small rodents and insectivores. The density of the vegetation would provide excellent nesting habitat for neotropical migrants such as the pine warbler. Snakes, water moccasins (Agkistrodon piscivorus), and copper heads could be found in this habitat, as could various small amphibians. Bottomland Hardwood Wetlands that border and grade into medium to large streams and rivers are typically of the bottomland hardwood forest variety. The primary sources of hydrology for this type of system are overbank flooding from the neighboring channel and groundwater flow to the stream. These areas are irregularly to seasonally flooded and contain mineral soils usually with a mucky surface, described as a hydric Muckalee loam in the Pender County Soil Survey (US Department of Agriculture - Soil Survey, Pender County, North Carolina). Vegetation typically found in the bottomland hardwood forests on the subject property include: red maple, sweet gum, green ash (Fraxinus pennsylvanica), and water oak (Quercus nigra) in the canopy; and poison ivy (Toxicodendron radicans) and laurel-leaf greenbriar in the vine stratum. Cinnamon fern (Osmunda cinnamomea), giant cane (Arundinaria gigantea), netted chainfern (Woodwardia areolata), and saw palmetto (Sabal minor) are found in the herb layer. A Shelter Creek Quarry IF IV271 SF G Functions and values associated with bottomland hardwood forests include flood retention, pollutant removal, erosion reduction, nitrogen and phosphorus reduction, and habitat for aquatic and terrestrial species commonly found in southeastern North Carolina. The thick vegetation found in these areas helps to slow flood waters, which in turn allows sediments and pollutants to filter out. The pollutants can then be absorbed into and, depending on the pollutant, bound to the soil. In addition, slowing flood waters (i.e., reducing the velocity) reduces the flow energy in the system and reduces, or prevents, destruction of the channel that may be caused by erosion. Mammals that would utilize this area for foraging habitat may include the raccoon and opossum. The water moccasin may frequent this area, as well as water snakes (Nerodia spp.), and yellow bellied sliders (Trachemys scripta). Avian species which may utilize this area include prothonotary warbler (Protonotaria citrea), pileated wood pecker (Dryocopus pileatus), barred owl (Strix varia) and wood duck. Swamp Forest Swamp forests, one of the most recognizable wetland types due to the presence of large cypress trees and little to no under story species, is a common wetland type along rivers in backswamps, sloughs, and oxbows in the Coastal Plain. These areas are seasonally to semi-permanently flooded to depths of up to several feet by stormwater flows, overbank flooding, and/or high groundwater levels. Common vegetative species include bald cypress (Taxodium distichium), swamp tupelo (Nyssa sylvatica var. biflora), and red maple. Under-story vegetation is usually only seen during drought conditions. In these cases, netted-chain fern (Woodwardia areolata), cinnamon fern (Osmunda cinnamomea), and laurel-leaf green brier may begin to invade. The functions and values and habitat utilization for swamp forests is very similar to those associated with bottomland hardwood forests. Wood ducks may utilize these are for nesting habitat, but the lack of mast producing species would limit its value for foraging. A frequent resident of swamp forests is the crawfish (Procambarus spp.), a significant prey species for raccoons and opossums. Beaver (Castor canadensis) and otters (Lutra canadensis) are commonly found in swamp forests. 911 jhelter Creek Quarry IP 1] 0/27] Status of Existing Mine at Time 5V 6i The mine site is located in an area that has been identified as low risk for sink holes. The geology of Pender County is mostly sand over-lying layers of clay and limestone that have been deposited over the last 100 million years. According to the map below, the areas most susceptible to sinkhole formation are associated with Tertiary limestone deposits. The mine site is located above a deposit of Cretaceous limestone, and thus, is at a lower risk for sinkhole formation. In addition, Mr. Steve Holland provided Mr. Floyd Williams, Chief Mining Specialist with the NC Division of Land Resources, a letter dated 25 July 2006, describing past mining activities near the proposed mine expansion site and lack of sinkhole formation associated with those activities (Attachment 2). The East Coast Limestone mine was located approximately 25 feet from NC 53, and pumped approximately 1,200,000 gallons of water daily. No sink holes were observed by the property owner, Mr. Bobby Goodson, nor were any reported by adjacent property owners. Mr. Ray Knowles, Road Maintenance Supervisor for NC Department of Motor Vehicles, had no knowledge of sinkholes or other problems associated with mining operations along NC 53 during his 25 year tenure. Mr. Holland also contacted the NC Forest Service and local farmers familiar with the surrounding properties. Neither of these groups knew of any sinkholes in the area, nor were they aware of any problems associated with drainage due to pumping at the former mine site.

Shelter Creek Quarry IF [ 1 11271 1 5F 61 Holly Shelter Creek and Water Source Holly Shelter Creek forms the southeastern property boundary of the project area. It is a third order, perennial stream, with a well-defined channel, approximately 18-feet wide. The ordinary high water mark is characterized by a defined impression in the bank, destruction of terrestrial vegetation, presence of a litter and debris, and a wrack line. Holly Shelter Creek is large enough to support a moderate benthic community. Six taxa of Crustacea, eight taxa of Mollusca, various fish species, and an American alligator (Alligator mississippiensis) were documented during the 2004 assessment for the Cape Fear River Basin Report.. The channel has a water quality classification of C, Sw. The "C" classification indicates that the stream is suitable for secondary recreation, which includes: fishing, aquatic life propagation and survival, and wildlife. It is not recommended for Class C water to come in contact with the human body. The "Sw" classification characterizes the channel as a swamp water with low velocity. Land use in the Holly Shelter Creek watershed is primarily silviculture, agriculture, and State owned game lands. There is very little residential development in this area. The main source of potable water in the North Carolina coastal plain is ground water, as it can be used in many parts of this area with minimal treatment. As a result, ground water is relatively less expensive when compared to other sources. The proposed project is situated above the Black Creek Aquifer. The Black Creek Aquifer is a huge reservoir located beneath more than fifteen coastal counties. The aquifer supplies water to communities such as Greenville, Jacksonville, Kinston, New Bern, and Rose Hill. This aquifer is present at elevations 317 to -1207 feet, averaging -135 feet. It ranges from 18 to 972 feet thick and averages about 175 feet thick (NC Division of Water Resources). Due to low permeability, the Black Creek Aquifer is slow to recharge, and growth in this region has surpassed the aquifer's ability to recharge itself naturally. In addition, as water is drawn out of the aquifer, the pore spaces it occupied collapse and the storage capacity is further reduced. The Black Creek Aquifer has been labeled as endangered by the North Carolina Division of Water Resources (DWR) and withdraws of greater than 10,000 gallons per day require registration, or for significant withdrawals, permitting is required. il. Shelter Creek Quarry Ii 1121271 Threatened and Endangered Species SEGO There are no known occurrences of federally-listed or state-listed species within the project area. Correspondence with the Natural Heritage Program (NHP) confirmed that there were no known occurrences of Federally or State listed threatened or endangered species within 2 miles of the proposed project. (Attachment 3) The only species identified within two miles of the project site was the American alligator. It is listed as threatened due to similarity of appearance, which does not afford this species any special protection. A site survey for listed species or potential habitat was conducted by Mr. Adrian Moon of Walton Engineering in January 2006. He did not locate any listed species or their habitat (Attachment 4). A second survey was conducted by Ms. Angie Pennock, of Southern Environmental Group, Inc., in May 2007. She observed longleaf pines (Pinus palustris) and loblolly pines that were approximately 8 to 10 inches in diameter, and were surrounded by a thick, shrub under story. No cavities or birds were noted on site. No appropriate habitat for other listed species was noted on-site during the second survey. The NHP has identified a Significant Natural Heritage Area in Angola Bay, northwest of the proposed project. According to the email dated 08 February 2007 (Attachment 3), from Ms. Misty Franklin of the NHP, Angola Bay has been identified as one of the largest, undivided peatland habitats in the state. It contains both short and tall pocosin types. According to the NHP Inventory of Pender County, Angola Bay is an approximately30-square-mile domed pocosin. This type of community is found only in the Coastal Plain of North Carolina. Most of this area is owned by the NC Wildlife Resources Commission. No evidence has been found to suggest the presence of eligible archaeological or historic resources on this property. ,'9 A41-A-C iI evu I - c?- 561ter CrccL Quarry IF [ 1 3/271 SF Gi i Angola Bay t I' r ' Significant Natural Heritage Area i I Imo.

Work at this site began in 2007, when the first cell was opened. The first area to be mined was in the northwest corner of the site. In order to obtain the maximum amount of available limestone, the applicant would be required to impact approximately 46.92 acres of jurisdictional wetlands. The majority of these areas are wetland pockets and fingers which extend out from larger systems. Due to the configuration of the on-site wetlands, the mine cannot be expanded without some wetland impact. The entire quarry would be mined in 4 phases, referenced as Phases IA, IB, IIA, and IIB (labeled on the impact map as P.IA, P.IB, P.IIA, and P.IIB). The first phase (identified as Phase IA) lies to the west of the existing dirt entrance road. The northernmost cell is currently open. Approximately 0.102 acre of wetland, found in the bottom of a man made channel, was permitted under a Nationwide Permit 39, for portions of Phases IA and IIA (Attachment I ). The 5he)ter CrecL Quarry IF [ 14127] SF G? Nationwide Permit was signed by Ms. Lillette Granade on 10 June 2006. A corresponding General Water Quality Certification 3402 (Project No. 060943) was issued on 26 July 2006 by Ms. Joanne Steenhuis (Attachment 5). Currently, the perimeter of Phase I A circumvents marginal wetland pockets. This is not the most efficient quarry configuration, as valuable limestone may be left in the ground. Said limestone would be attainable with a less convoluted footprint. Impacts requested for Phase I A, associated with this Individual Permit request, would be to expand the currently permitted footprint, so that the mine edges would match the setback requirements. Current proposed wetland impacts for the expansion of this phase are referred to as A, B, C, and D (Attachment 6), and total approximately 17.7 acres. The pump water collection system has been developed as part of Phase IA, and is currently in operation. The pump water collection system pumps water to the Horseshoe Pond, where the water's chemistry and clarity are tested. If necessary, additives will be dispersed in the water as remediation. The water then discharges into the Level Spreader Pond, where the water level is regulated by triple gate valves. If necessary, the water quality can be inspected in this reservoir. The water is then released through the valves to the large central wetland system. The plan for this system can be found in the Hydrology Monitoring Plan (Attachment 7). The second phase of the mining operation would be Phase IIA. Wetland impacts associated with this phase, which is found to the east of existing entrance road, were authorized under the same permit as Phase IA. Again, the original mining footprint was designed to circumvent most marginal wetland areas. The applicant would like to alter the existing footprint, so that the revised footprint would match the required setbacks. This would grant the quarry operators to access additional limestone, and is the same scenario as Phase IA, described supra. It is anticipated that Phases IA and IIB, as currently permitted, would be mined out in 12 to 14 years (See Attachment 1). The proposed wetland impacts associated with the expansion of Phase IIA are labeled as AA, BB, CC, DD, and EE, and total approximately 12.18 acres. The third phase, IB, is found to the south of IA. No part of IB has been authorized to date, and wetland impacts in this phase include those to areas E, F, G, and H. The proposed impacts for Phase IB total approximately 4.4 acres of jurisdictional wetlands. The mine operators would prefer to commence activities on Phase IB only after the completion of Phase IIA, as they feel (q jhelter C,rccL Quarry Ir 1151271 5r 6i this would be the most efficient manner to utilize the mobile crusher and pump. In addition, it would reduce any potential access issues to Phase IB. Reclamation of each Phase would be completed as soon as mining activities at that location have ceased. Phase IIB would be the final section of the quarry, and is to be located to the south of Phase IIA. Proposed wetland impacts associated with Phase IIB include those areas labeled FF, GG, HH, II, JJ, KK, LL, and MM, which total approximately 12.64 acres. After the final shaping and remediation of Phase IIB, the Shelter Creek Quarry would be closed. The resulting pits and freshwater reservoir could potentially be used by the citizens of Pender County. There are no impacts proposed to Holly Shelter Creek. The quarry developers are committed to retaining the natural condition of this creek. A buffer along this channel will be maintained and no impacts are proposed within fifty (50) feet of the stream.

Sequence of events The applicant would like to begin work on Phase IB as soon as Phase IIA has been completed. It is anticipated that this will occur sometime within the next 7 years. The construction sequencing will remain consistent for each phase of the mine. The necessary berms and stormwater diversion structures will be constructed first, then connected to the existing systems. Silt fence will be installed in upland areas, adjacent to wetlands that are not proposed to be impacted. Overburden will be removed, then used to construct on-site features, ?b Shelter CreeL Quarry IF 11612-71 SE-6I 1 roads and berms. Chain link fencing will be placed on top of all berms. Excess overburden will be stored on upland areas within the project boundary. The excavation of the mining pits in each section will begin with a sinking cut, down to a collection area, where a floating pump will be installed. The perimeter of the initial hole will be expanded until the section has been mined to the maximum extent possible. The final conformation for each pit will be constructed and graded, with any excess overburden being placed in the bottom of the pit. The final configuration may include a littoral shelf, approximately 50 feet wide, grading from vegetated shallows to swamp and bottomland hardwood forests. The equipment, including the mobile crusher and pump system, will be moved to the next section and the process repeated. Please note, each phase will be reclaimed as soon as mining has ceased in that phase. Purpose and Need The purpose of the Applicant's proposed project is to expand an existing limestone quarry in northeastern Pender County. The expansion of this quarry will provide various products for use in this region, and other parts of North and South Carolina. This project is not water dependent, in that there are potential alternatives that would not require the utilization of surface waters. Limestone is a sedimentary rock, formed from the shells of ancient organisms. The organisms responsible for the Cretaceous limestone deposits found at the mine site lived 140 to 65 million years ago. At that time, this region of southeastern North Carolina was located beneath a shallow sea. Under this Cretaceous limestone deposit, a bedrock of harder igneous and metamorphic rocks are found. These are more similar to the strata found in the Piedmont. Since the species necessary to form limestone are typically found in shallow seas and the rock strata of the Piedmont is predominantly made of harder bedrock, the Coastal Plain is the best location to find limestone. Limestone is a softer stone than granite. For this reason, it is preferred for use in concrete and in concrete mixers. According to Mr. Steve Dorenda, when granite is used in concrete mixers, it quickly destroys the mixing apparatus. After each alternate load, the mixing truck must be emptied and the mixer replaced. When limestone is used in place of granite, the damage to the mixing apparatus is significantly reduced, and replacements are required at less frequent s? ? Shelter CrccL Quarry IF 1171271 "5F -6i intervals. This constitutes a significant cost reduction for concrete companies, and is their preferred method for mixing. Many of the new homes, and other constructed buildings in southeastern North Carolina, are built on slabs of concrete. Even in the event that a crawlspace is constructed beneath the dwelling, concrete footers are required to support load bearing walls. In addition, concrete is used in the construction of driveways, sidewalks, curbs and gutters, culvert pipes, and foundation blocks. Another product of limestone quarries is rip rap. These larger stones are used on almost every construction site in southeastern North Carolina, for stabilization and filtration, which assists in preventing excessive sediments from entering the waterways. The United States Geologic Survey (USGS) tracks mining activities nationwide, and records important mining statistics for each state. Over the last ten years, crushed stone has accounted for between 70% and 72% of all mined material nationwide, and North Carolina has ranked between 8th and 10th for crushed stone production during this period. During this period, crushed stone production has increased in all but three years. (Attachment 8) Mining is a significant industry in our nation's and our local economy and infrastructure. According to the USGS, in 1995, 16% of the mining operations in North Carolina were crushed stone facilities. North Carolina has eight specific forms of rock utilized for crushed stone: limestone; dolomite; calcareous marl; granite; traprock; quartzite; slate and volcanic cinder; and scoria. In 1995, limestone was the second-most mined material, behind granite. In 2004, crushed stone continued to lead the market in the North Carolina mining industry, and again, the second highest rock mined for this purpose was limestone. While there have been slight decreases in crushed rock production nationwide in three of the last ten years, there have been no decreases in crushed limestone production in southeastern North Carolina. 291 Shelter Creek Quarry IF 1181271 Sr-6I Year 'Crushed Rock as Percenta e g of Minerals Mine NC.Rankiii m ?'

North Carolina's ranking in crushed rock market over the past decade. Currently there are three crushed stone quarries in southeastern North Carolina: the subject quarry; one operated by Wells Limestone Mine in Duplin County; and the third, operated by Martin Marietta Aggregated in Pender County. The mining permits for each of these facilities may be expiring within the next six years (Steve Holland, personal communication). Historic mines in the region have closed, including the East Coast Limestone mine, which was in operation for 25 years, and was located on 250 acres to the north and northwest of NC 53. As there are so few remaining mines in the area, there is a definite need for an additional mine in this region. The Shelter Creek Quarry is situated in an ideal location for a large limestone mine, as there are confirmed substantial volumes of limestone present. The mine site is located in a rural, extremely sparsely populated portion of Pender County. The increase in traffic and noise associated with the mine will not impact many individuals. The neighboring properties are owned by Mr. Steve Holland and the State of North Carolina. The lack of numerous adjacent property owners makes the monitoring of these areas for potential secondary impacts a much nA 5kelter CreeL Quarry IF 1191271 SEG easier task, then if there were many, small, privately owned tracts. There are approximately 8.5 million tons of limestone in Phase IA and HA and an estimated 15 million tons under the entire proposed mine site (Steve Holland, personal communication). This project could produce large volumes of a highly sought-after commodity, and also may result in many new jobs in this region. Alternatives The Applicant investigated other potential means of expanding the existing quarry, and has been unable to find a practicable alternative that would achieve their goals and meet their stated purpose. • No-Build: The no-build alternative, or the alternative that would not require the construction of any structures for the purposes of mining, would be to utilize a portable drill to reach the limestone at various locations on the property. This is not a practicable alternative, as the removal rate for the limestone would be so slow, it would preclude any marketability. • No action: No action alternatives include those project designs that do not require the issuance of a Department of the Army authorization. For this project, this would require the expansion of the mine to have no additional wetland impacts. This not a practicable feat, given the configuration of the wetland complexes found on the subject property. There is simply not enough space between the remaining wetlands to effectively install an additional mining area. Another no action alternative is to tunnel down to the limestone, remove it, then ship the limestone to another facility for crushing. There are tremendous, intrinsic safety hazards associated with tunnel mining, including noxious/toxic gases and tunnel collapses. In addition, the shallow nature of the water table in most of southeastern North Carolina would preclude the excavation of tunnels to a depth necessary to reach the limestone. It would not be financially prudent to ship the stone to an off-site company for crushing. These reasons point to tunneling being an impracticable alternative. Shelter CreA Quarry IF [20/271 • Other project designs: SEGO The Applicant has reviewed several possible configurations for the'quarry expansion, including leaving Phases IA and IIA as they are currently permitted, and eliminating one, or both, of Phases IB and IIB. The applicant has determined that leaving the project as currently permitted, or eliminating any of the proposed new sections, would result in not mining anywhere from %- to %2- of limestone that can be mined outside of the bottomland hardwood forest (that is proposed to be preserved as part of this project). Given the need for this product, and the limited area from which it can be obtained, leaving a large portion of the potential reserve in the ground would not be feasible for the applicant. In addition, it would not allow the property owner, mine operator, or the management company to realize the expected reasonable return or the full benefit of their financial investment. For these reasons, the applicant believes that leaving the project as currently permitted or eliminating the proposed new sections is not a practicable alternatives. Other project locations: Another alternative that was discussed was the possibility of constructing the mine in another location. This is not a practicable alternative, as the proposed project is the expansion of an existing mine. It is highly unlikely that a site in this region could be found, and mined, with significantly fewer impacts to aquatic resources than those proposed. In addition, the Applicant would also incur a whole new set of start-up costs, including: geological surveys; biological surveys; water table monitoring; purchasing the additional property; purchasing additional equipment; and, constructing all new mining infrastructure. The optimum limestone conditions are limited to an area that stretches from northeastern Pender County southwest to Brunswick County, and west to the fall line. Most of this region is characterized by relatively flat topography and many acres of wetlands. Similar to northeastern Pender County, western Brunswick County is extremely rural, though a good portion of western Brunswick County is comprised of an area known as the Green Swamp. The largest documented portion of high ground in this area is the current site of a new landfill. It is unlikely that a mine could be constructed in the Green Swamp with jhelter CreeL Quarry IF 121127) 5E-6i less impact to aquatic resources, and it is unlikely the Applicant would propose a mine in an area dedicated for use as a landfill. The western portion of this range is simply too far from the major development zones along the coast. The cost of shipping the material would make it less attractive to customers. Finally, moving the mine site from northeastern Pender County to another location would not meet the Applicant's stated purpose and need. • Minimization: The current proposal requests impacts to wetlands that are predominantly marginal examples of their type, and are either relatively small pockets, or the upper fingers stemming from larger off-site wetland systems. The Applicant has worked diligently to avoid the most functional wetlands on-site, namely the swamp forest located along Holly Shelter Creek, and the large, 119.2-acre bottomland hardwood forest, found directly in the center of the southeastern project area. The developers of this site are choosing to utilize innovative measures to ensure the continued good health of the remaining on-site wetlands, and neighboring off-site wetlands. According to the Hydrology Monitoring Plan and the Operation and Maintenance Plan (Attachments 8 & 9), hydraulic barriers, water cannons, and an innovative multiple gate discharge system will be utilized, to ensure that neighboring wetlands will not be drained during those times when pumping occurs in the pits. Closed ditches along the eastern and western property lines (3 feet deep with 2:1 side slopes) will be excavated. The ditches will be flush with water at all times, via a pump system. This will create a hydraulic barrier, which will prevent the drainage of adjacent wetlands on the NC State Gamelands property or on Mr. Holland's property. Water cannons will be used to spray water over remaining on-site wetlands, with the exception of the large bottomland hardwood swamp. The large wetland complexes on the southeastern side of the property, and along Holly Shelter Creek, will be protected via the discharge system. The drainage system mentioned supra should not be confused with a stormwater system. The difference is, water in the discharge system originates from the mine pit, not from precipitation events. A maximum volume of 2 million gallons per day may be pumped jhelter CrecL Quarry IP 122/271 SE-6i from the mine pits. As the site will be mined in phases, and each phase will be reclaimed as it is completed, a maximum discharge of 500,000 gallons of water per day seems more likely. The water will be pumped from the mine pit to the Horseshoe Pond, where chemical testing will occur to ensure no contamination occurs. The water will then be transported to the Level Spreader Pond. At the release point on the Level Spreader Pond, the mine operator installed a triple gate value system, which will be used to control the volume of water being released into the bottomland hardwood wetland. At maximum discharge, this would result in approximately 4194 gallons of water being dispersed on each acre of wetlands per day, which is less than half the volume that is discharged through rainfall alone. And, due to the fact that sheet flow from the neighboring uplands to the large wetland area will be eliminated, additional water will be necessary to maintain this system. If too much water is entering the bottomland hardwood area, the valves can be closed, and the water levels allowed to drop. In the event of a large storm, the valves can be closed and pump turned off. This will allow the mine pit to hold the additional influx of water, and will assist to mitigate the impacts of the flood. The flood waters will slowly be pumped out, and mining activities will resume. Due to the fact that the quarry expansion has been designed to avoid the most functionally valuable wetlands, was designed to impact the least functionally valuable wetlands, and the expansion provides for measures to ensure the health of the remaining on- and off-site wetlands, it is the Applicant's sincere belief that the proposed expansion plan is the least environmentally damaging, practicable alternative. Proposed Compensatory Mitigation On-site, in-kind mitigation is typically preferred for compensatory mitigation. The Applicant proposes to create on-site wetlands as part of the mine reclamation process. Mr. Holland will also be preserving the large bottomland hardwood forest located on the southeastern side of the property.
