APPENDIX D WES09620.RFr I Wetland & Environmental Services Hendersonville Quarry I INTRODUCTION This report presents the results of a routine on-site delineation of waters of the United States (waters), including wetlands, on the approximately 160 acre Hendersonville Quarry, Vulcan Materials Company. The delineation focused on an area of proposed quarry expansion onto two parcels east of the active pit and one area south of the pit. In addition, a wetland determination was conducted on the remaining land within the quarry boundaries to generally locate waters of the United States outside of the proposed quarry expansion limits. This determination is the subject of a separate report. The property is located in Henderson County, approximately two miles north of Hendersonville, North Carolina at the intersection of Clear Creek Road (SR. 1503) and Howard Gap Road (S.R. 1006). The Hendersonville Quarry lies within the Clear Creek watershed. (Figure 1.) The property is owned by Vulcan Materials Company. This evaluation was conducted,by Wetland & Environmental Services (WES) under contract with the owner's engineer, Marshall Miller & Associates, Bluefield, Virginia (WES Project Number WES09620). Project Objective Scope of Work The principal objective of this evaluation was to identify and delineate the boundaries of jurisdictional waters of the U.S., including wetlands, on the parcels regulated under the Federal Clean Water Act (CWA). To meet the project objective, the following general work tasks were performed: 1. Review pertinent literature and documentation readily available in the public record and those provided by the Client to identify the presence of jurisdictional areas on the property. 2. Perform on-site investigation to identify and delineate jurisdictional wetlands and waters. Methods This section presents the methods employed under the scope of work to meet the project objectives. Wetlands at the project site were delineated in accordance with the Corps of Engineers 1987 Wetland Delineation Manual (ACOE 1987) and subsequent regulatory guidance memoranda. WES09620.RPT 1 Wetland & Environmental Services Hendersonville Quarry Preliminary Data Gathering and Synthesis An initial off-site review was performed in accordance with Part IV, Section B of the Manual "Preliminary Data Gathering and Synthesis." As part of this review, the following information sources were compiled and reviewed: 1. United States Geological Survey Topographic Map, 7.5 Minute Quadrangle; Hendersonville Quadrangle (Figure 1). 2. United States Department of Agriculture Soil Conservation Service (now the USDA Natural Resources Conservation Service, NRCS) Soil Survey of Henderson County (Figure 2). 3. United States Fish & Wildlife Service National Wetland Inventory map, Hendersonville 7.5 Minute Quadrangle (Fig. 3). 4. NRCS Food Security Act Swamp Buster and Sod Buster maps of prior converted cropland and highly erodible soils. (Reviewed at the Hendersonville office of the Agricultural Stabilization and Conservation Service.) Sources were reviewed and evaluated for the presence of characteristics consistent with the occurrence of wetlands. Factors considered include, but are not necessarily limited to: slope, proximity to surface waters, presence or absence of hydric soils or soils with hydric inclusions, and current land use. Areas of particular interest were identified for specific inspection during scheduled field work. Field Investigation Descriptive releves were conducted during a thorough traverse of the property, following Bonham (1989), generally noting significant changes in plant communities, soils and hydrologic indicators. As changes in plant community or hydrologic indicators were noted, soils samples were randomly taken to confirm the proximity to areas exhibiting all three parameters of wetlands. Data points were established to confirm general observations in areas across the site to confirm or refute original speculation that wetlands may occur at that each location. Plant community assessment procedures were performed in accordance with the field indicators and sampling techniques described in Part III, Paragraph 35 and Appendix C of the Manual. Dominant species from each stratum were estimated by visual observation of abundance. Vegetative data were interpreted and indicator status was assigned using the U.S. Fish and Wildlife Service's Region III Wetland Plant List (Reed 1986). This document WESO%20.RPT 2 Wetland dt Environmental Services Hendersonville Quarry classifies plant species according to the frequency of occurrence in wetlands (See the table). Nomenclature for taxonomic identification follows Radford et al (1974). To meet the criteria for hydrophytic vegetation more than 50 percent of all dominant species must be obligate (OBL), facultative wetland (FACW) or facultative (FAC) species. PLANT INDICATOR SYMBOL DEFINITION CATEGORY Obligate Wetland OBL Plants that occur in wetlands > 99% of the time Facultative Wetland FACW Plants that usually occur in wetlands (67-99%) Facultative FAC Plants equally adapted to wetland & upland conditions (33-67%) Facultative Upland FACU Plants that sometimes occur in wetlands (1-33%) Obligate Upland UPL Plants that very rarely occur in wetlands (<1%) Hydric soils were evaluated consistent with Part III, Paragraph 44 of the Manual. Mapped soils were compared to listed hydric soils in Hydric Soils of the United States (USDA-SCS 1991a) and the county hydric soils list (USDA-SCS 1991b). All soil samples were taken using a hand auger to a depth of at least 12 inches. Soil colors were determined from moist, undisturbed peds using the Munsel Soil Color Charts (1975 and 1991 editions) and the abundance, contrast and size of redoxymorphic features were described. Soil texture was determined, approximately, by feel and the terminology describing texture is consistent with the USDA soil texture classes. The hydrology criteria was evaluated using visual observation of hydrologic field indicators as described in Part III, Paragraph 49 of the Manual and subsequent guidance. Wetland hydrologic field indicators include soil saturation, wetland drainage patterns, watermarks, blackened leaves, oxidized rhizospheres, recorded data and others. Wetlands were delineated using the three parameters above and areas identified as jurisdictional were flagged approximately every fifty feet. When other waters (including streams and intermittent drainages) were present, these areas were delineated based on the application of the hydrology parameter alone (relying on primary indicators) and the regulatory definition of ordinary high water (33 CFR Part 328). Swales and channels were traced up gradient until no signs of channel flow and no springs were WES09620.RPT 3 Wetland & Environmental Services Hendersonville Quarry found. In most cases, the channels and swales included as jurisdictional area were flagged at the top-of-bank of the channel. RESULTS Off-Site Methods The site is located within the Clear Creek watershed of the Blue Ridge Mountains physiographic province, approximately 30 minutes south of Asheville, North Carolina. Elevations range from approximately 2100 to 2300 feet, National Geodetic Vertical Datum. The property is roughly bounded on the south, west and north by state-maintained roads, while the eastern boundary extends from the approximate limits of quarry activity on the north to property lines along pasture and recent development and an existing orchard along the southeastern border. A power line right of way crosses the lower third of the property in an east-west direction. Three tributaries to Clear Creek, mapped as perennial (blue line) streams, originate on or near the property on the east, south and west boundaries. At the headwaters of the southern tributary, an active sediment basin is maintained as part of the mining operation's National Pollutant Discharge Elimination System permit (NPDES permit No. NCG 020000) and receives pump discharge from the active quarry. (Figure 1.) The site is characterized by soils of the Evard-Edneyville-Ashe and Hayesville-Bradson associations, which are gently sloping to very steep, well drained to somewhat excessively ' drained loamy to clayey soils. Soils mapped for the site are predominantly Edneyville and Hayesville soil series, with other map units making up a smaller portion of the site. (See table and Fig. 2). Soil Name Map Unit Ashe stop sand loa m, 15-25 percent AhF Bradson gravelly loam , 2-7 percent BaB Bradson gravelly loam , 7-15 percent BaC Edn ille fine sand lown, 15-25 percent EdE Ha esville loam, 7-15 percent Tate fine sand loam, 2-7 percent TeB Tate fine sand loam, 7-15 percent Tec Boldfaced soils are listed as Hydric ' Soils with hydric inclusions WES09620.RPT 4 Wetland & Environmental Services Hendersonville Quarry From the Henderson County hydric soils list (USDA SCS 1991), no hydric soils or soils with hydric inclusions were mapped for this property. Inspection of the Food Security Act maps in Hendersonville revealed that no areas were mapped as prior-converted or farmed wetlands in the vicinity of the property. The National Wetlands Inventory map (Figure 3) shows three, permanently flooded, excavated areas (PUBHx) within or near the property boundaries. Only the southernmost area (which corresponds to the sediment basin) occurs within the proposed quarry expansion. On-Site Methods Site visits were conducted on September 23 - 26, 1996. From the off-site review; it appeared that a number of swales within the property boundaries would be likely to support wetland vegetation, although soils information did not support this. The entire site was walked, and 5 transects or sample points were established concurrent with wetland delineation. Site photos were taken at several locations and are presented in Appendix B. Wetland delineation data sheets are presented in Appendix C. In general, the site is dominated by mixed oak-hickory forest, with scattered white pine (Pines strobus). Prevalent species include white oak (Quercus alba), red maple (Acer rubrum), mockernut hickory (Carya tomentosa), tulip poplar (Liriodendron tulipifera), sourwood (Oxydendrum arboreum) and occasional white pine (P. strobus). Understory and shrub species include American holly (Ilex opaca), dogwood (Corpus florida), mountain laurel (Kalmia latifolia) and juvenile components of the canopy layer. Moist to wet areas included rhododendron (Rhododendron maximum), elderberry (Sambucus canadensis), highbush blueberry (Vaccinium corymbosum) and black gum (Nyssa sylvatica), while the herb and woody vine layers contained a variety of ferns, greenbrier (Smilax rotundifolia), fox grape (Vitis labrusca), japanese honeysuckle (Lonicera japonica), and Chinese silver grass (Miscanthus sinensis), which occurred as a dominant in some areas. One wetland area located in Swale 1, which represents the major extant wetland on the property, is dominated by rhododendron, greenbrier, cinnamon fern (Osmunda cinnamomea), New York fern (Thelypteris noveboracensis), and highbush blueberry with a canopy of red maple, blackgum, and tulip poplar. Soils of the upland sites were typically well drained loamy soils with a Munsell color at 10 inches (or immediately below the A horizon) of 5YR5/4 to 10YR4/4. Soils of the wetland areas were a fine sandy loam to silt loam, with Munsell colors of 2.5Y5/2, with bright mottles, WES09620.RPT 5 I Wetland & Environmental Services Hendersonville Quarry to 10YR4/1. One area (Swale 2) did have soils with a low chroma at 10 inches (see Appendix C), however wetland hydrology did not occur at this location. Upland areas typically lacked primary or secondary indicators of hydrology. Swales numbered 2 and 3, although containing remnants of incised channels in some locations, did not appear to receive more than ephemeral runoff. These areas lacked evidence of surface scour or a clearly demarcated line of vegetation indicative of waters of the U. S. Wetland areas supported flowing, spring-fed streams and were saturated within 10 inches of the surface in most areas. Redoxymorphic features (oxidized rhizospheres, iron masses, and an abundance of manganese concretions in one area) were present. Two separate wetlands complexes were located and flagged. The first area, labelled "Swale 1" on the delineation data sheets (flags 1-1 to 1-35), consisted of a spring and seep fed floodplain wetland complex which extended to the property boundary and further downstream. The second area included outfalls from the sediment basin, a downstream farm pond, flagged in series 3-1 to 3-14 and 4-1 to 4-4, and ditched channel (which serves as the property boundary, and was not flagged) and a separate area (data point 4 and flags 5-1 to 5- 13). This last area appears to be subject to overbank flooding at the farm pond spillway and meets the definition of jurisdictional wetlands. An on-site meeting was held on October 26, 1996 with Mr. David Davis, Mr. Leo C. Snead, Jr. (WES) and Mr. Steve Chapin (Asheville Field Office, Wilmington District, Army Corps of Engineers) regarding flagged jurisdictional boundaries. Mr. Chapin verbally confirmed the delineation in the field on that date. Figure 4 presents the surveyed location of all identified and flagged waters of the U. S., including y wetlands. Areal extent of delineated jurisdictional areas is 0.63 acres (27137 square feet), which is listed, by area, on Figure 4. Upon receipt of this written report and surveyed locations, Mr. Chapin will issue a written confirmation of this delineation. REGULATORY STATUS AND PERMIT REQUIREMENTS Waters of the United States, including wetlands, are regulated at the Federal level under Sections 401 and 404 of the Clean Water Act (CWA).. Section 404(b)(1) of the CWA authorizes the Corps to regulate fill in jurisdictional areas with oversight by the U. S. Environmental Protection Agency (EPA). Placing fill in jurisdictional areas can require an individual permit from the Corps, which may be a time-consuming process. The Corps administers a program of Nationwide Permits (NWP) that are intended to reduce or eliminate paperwork for activities that are considered to have minor impact on the environment, provided certain minimum criteria are met. WES09620.RPT 0 Wetland & Environmental Services Hendersonville Quarry All areas within the property boundary fall under NWP26 in that the areas are within the headwaters of streams (less than 5 cfs discharge). Under this permit, up to one acre of I regulated area may be filled, although proposed changes to this nationwide may result in a ?l lower threshold in the near future. For fills from one to 10 acres, the Corps may, at its discretion, issue a NWP26 or require an individual permit. Individual permits are required for filling over 10 acres. Activities that require federal 404 permits, including Nationwides, may be subject to coordination with the US Fish & Wildlife Service for endangered species and the State Historic Preservation Officer for cultural resources. I Issuance of Section 404 also requires water quality certification under Section 401 of the CWA. The Department of Environment, Health & Natural Resources, Division of Environmental Management (DEM), issues water quality certification. For NWP26, activities impacting greater than 1/3 acre of waters, including wetlands, require notification and written authorization by DEM. In addition, because Henderson County streams are listed Trout Waters, impacts in excess of one acre require public notice and an individual 401 water quality certificate. The North Carolina Wildlife Resources Commission has designated the 25 western-most counties of North Carolina as "trout waters." In these areas, which includes Henderson I County, all activities requiring a permit (including nationwide permits) require notification to the Commission.

Snead, Jr.; PWS, President (B.S. in Biology, Old Dominion University, 1979; Graduate work in the Ecology Curriculum, Rutgers University, 1982-1985) Mr. Snead has an academic background in aquatic and wetland ecology and over fifteen years of experience in four states (MD, NC, NJ & VA) in tidal and nontidal wetland mapping, policy and resource management, with supervisory experience in the Commonwealth of Virginia's Section 401 program. He has direct experience reviewing and writing draft nontidal wetland legislation in two states and has a strong understanding of Section 404 requirements and limitations. Since the late 1980's, Mr. Snead has taught wetland delineation methods, following the 1987 Corps Wetland Delineation Manual, in both Virginia and Maryland, and has participated as an active member in a state task force which reviewed proposed changes to delineation methods in 1991. In 1995 he was invited as one of two consultants in Virginia to assist in reviewing proposed congressional changes to the federal wetland definition (S. 851 and H. R. 961). In addition, Mr. Snead has participated in endangered species surveys and has developed endangered species and exotic species management plans. He developed draft mitigation guidelines while at DEQ, he has performed wetland delineations on sites ranging from 6 to 150 acres in size, and develops and implements wetland mitigation plans for tidal and nontidal wetlands. He is the past Vice President of the Virginia Association of Wetland Professionals and currently sits on the association's Delineation Certification Committee. In December 1995, Mr. Snead received his Professional Wetland Scientist certification from the Society of Wetland Scientists. J C. Snead, Jr.; WS President David L. Davis; C.E.I., PWIT, Senior Biologist. (BS in Biology, The College of William & Mary, 1989; Graduate Work in Coastal Botany and Wetland Ecology, Virginia Institute of Marine Science, 1989; 40-Hour Occupational Health and Safety Training, 1992; Environmental Inspectors Course Work, Environmental Assessment Association, 1995): Mr. Davis has over seven years experience in environmental laws and regulations, specializing in Sections 401 and 404 (Clean Water Act), Section 10 (Rivers and Harbors Act), Section 7 and 9 (Endangered Species Act), Chesapeake Bay Preservation Act, and the National Environmental Policy Act (NEPA). Mr. Davis has performed over 250 wetland delineations, over 300 Phase I environmental site assessments, over 100 endangered species surveys in two states, and has performed field work and written over 50 NEPA documents. Mr. Davis has extensive experience in wetland delineation, wetland mitigation design and construction, plant taxonomy, endangered species surveys and natural resource studies. He is certified by the U.S. Fish and Wildlife Service-Virginia Field Office to conduct surveys for the federally protected small whorled pogonia (Isotria medeoloides). Mr. Davis is also certified by the Environmental Assessment Association as a Certified Environmental Inspector (No. 13102), and by the Society of Wetland Scientists as a Professional Wetland Scientist in Training. David L. Davis; C.E.I., PWIT Senior Biologist WES09620.RPT Appendix E Erosion & Sediment Control Narrative Wetland & Environmental Services Permitting, Environmental Inventories & Planning Erosion and Sediment Control Plan I The erosion and sediment control principles for this project are to convey runoff and to collect and allow settling time for sediment laden runoff prior to discharge from the site. The North Carolina Erosion and Sediment Control Planning and Design Manual has been adhered to and used for guidance during the development of this plan. All structures are designed based on the 25 year-24 hour storm event. The main erosion and sediment control structures for this project are rock dams and conveyance channels. Silt fence (Practice 6.62) will be used in isolated instances where land disturbance is minimal and the time duration is short. Slope drains (Practice 6.32) and temporary sediment traps (Practice 6.60) have been included in the design, in case, the need may arise for a temporary measure during construction. Basins I, HA, and ID3 were approved in a mine plan revision dated March 15, 1995. This proposed plan is very similar to that plan approved in March, 1995. Appendix B contains computations which show the original design and sizing of these three basins is sufficient for this mine plan revision. .Peak Runoff Runoff is computed using the rational method, Q=CiA where: Q = Peak rate of runoff in CFS C = Runoff Coefficient i = Intensity of rainfall in inches/hour A = Drainage area in acres The runoff coefficient, C, and time of concentration, Tc, for this project have been computed on an individual basis. Refer to Design Computations in Appendices A and B. -Rock am (Practice 6.63) Rock dams are utilized on the project to treat sediment laden runoff prior to discharge from the sight. The basin volumes are based on 1800 cubic feet of storage for each acre of drainage area. The spillways are sized to pass the 25 year - 24 hour storm, The embankments have a minimum width of 5 feet with the upstream slope at 2:1 and the downstream slope at 3:1. Embankments shall be underlain by a 2 foot by 2 foot cutoff trench. The rock embankment shall be constructed of stone with a minimum d5o = 9" and the upstream face shall be covered with a NCDOT #57 stone filter layer. Trap efficiency has been designed so as to prevent short circuits from inlets to outlets and the detention time is at least 8 hours. The surface area is sized to provide 0.01 acres per CFS of runoff. .Conveyance Channels (Practice 6.30 and 6.31) The conveyance channels are sized based on the 25 year - 24 hour storm. The channel dimensions are evaluated for capacity and velocity (based on the design retardance class). Then they are evaluated at a retardance class one higher than design to account for vegetative growth and debris build-up. Once the dimensions are established then the temporary lining is designed. Channel linings for this project are grass and riprap. Channel linings are designed using the Tractive Force Procedure. -Temporary Seeding (Practice 6.10) Temporary seeding is to be applied to all disturbed areas where work is delayed for a period of more than 30 days but not more than one year. -Permanent Seeding (Practice 6.11) Permanent seeding is to be applied on areas which have been brought to final grade or areas which are rough graded and will not be brought to final grade within a year or more. -Vegetative Screen - Trees, Shrubs, Vines and Ground Covers (Practice 6.13) Trees, shrubs, vines and ground covers shall be used in areas where a vegetative screen is necessary and existing vegetation does not exist. .Land Grading (Practice 6.02) All cut and fill slopes in unconsolidated material will be no steeper than 2:1 with a minimum 10 foot horizontal bench at each 30 foot elevation interval. Cut slopes will be fine graded immediately after rough grading and will be vegetated according to the Vegetation Plan. As the disposal areas are created, the material shall be placed in even layers and compacted. Vegetative measures shall be applied according to the Vegetation Plan and the regulations set forth for temporary and permanent seeding. .Tree Preservation and Protection (Practice 6.05) Trees and other vegetation will be preserved as much as possible for their screening, landscape and erosion protection value.
