The volume of runoff from the site can be calculated by multiplying the area of die site by the runoff depth. Step 4. Determine the peak rate of runoff for the design storm by adjusting for watershed shape as follows: a. Determine an "equivalent drainage area" from the hydraulic length of the watershed using Figure 8.03n. Hydraulic length is the length of the flow path from the most remote point in the watershed to the point of discharge. b. Determine the discharge (cfs/inch of runoff) for the equivalent drainage area from Figure 8.03o through 8.03q: Figure 8.03o - for average watershed slopes 0-3% Figurz.8.03p - for average watershed slopes 3-7% Figure 8.03q - for average watershed slopes 8-50% Calculate the peak discharge, 01, of the equivalent watershed by multi- plying equivalent watershed area by runoff from Table 8.03c in Step 3b. 8.03.17 ear • t 20000 ?- 10000 w w w 0 = 5000 LO F- Q 3 ?L 2000 0 t L= 209o 0'6 WHERE L=HYDRAULIC LENGTH, FEET a=DRAINAGE AREA, ACRES F- z 1000 U-1 J 500 L 10 20 50 100 200 500 2000 DRAINAGE AREA, ACRES Figure 8.03n Hydraulic length and drainage area relationship. c.

Nethery, Senior Environmental Scientist C. Fred Davis, Environmental Scientist Report Preparation by: William R. Nethery September 1, 1995 EXECUTIVE SUMMARY A protected species survey and wetland delineation were conducted in August 1995 for the proposed Surry County Landfill expansion north of the Ararat River, south of Stoney Creek, and southwest of Mount Airy in Surry County, North Carolina. The project property, approximately 115 acres in size, contains seven ecological communities: Agricultural/Field, Disturbed Hardwood-Pine Forest, Pine Forest, Oak- Hickory Forest, Mixed Mesic Hardwood Forest, Chestnut Oak Forest, and Aquatic Habitat. Several ravines and slopes in the project property contain mature ecological communities. Upper slopes, ridges, and some drainages contain agricultural fields or forests recently disturbed by timber harvesting or storm damage. Information on previous occurrences of protected species near the project area was obtained from the U.S. Fish and Wildlife Service and the North Carolina Natural Heritage Program at the time of the survey. The project area and adjacent areas contain habitat or marginal habitat for four state protected animal species: brook floater, mole salamander, four-toed salamander, and Wehrle's salamander. No evidence of any state or federally protected animal species was observed in the project area. The project area contains habitat fcr one state and federally protected plant species, small-whorled pogonia. No state or federally protected plant species were observed in the project area. Because of the degree of disturbance in many places, much of the project area is not likely to contain protected species. Due to the presence of natural communities suitable for a state protected mussel, several state protected salamanders, and the state and 'federally protected small-whorled pogonia, we recommend avoidance of impacts to .perennial Aquatic Habitat, Oak-Hickory Forest, Mixed Mesic Hardwood Forest, and Chestnut Oak Forest communities on steep slopes and-ravines to the extent practicable. Avoidance of impacts to these commmunities will be easy in the legally required buffer zones on. perennial waters and property boundaries. Where impacts to mature hardwood forests cannot be avoided, we recommend consultation and possible intensive survey of these areas by a local salamander biologist for mole salamander, four-toed salamander, and Wehrle's salamander. We also recommend a return survey during the growing season (April-May) to determine the presence of small-whorled pogonia.

The project property is approximately 115 acres in size and is located between the Ararat River and Stoney Creek west of their confluence (Figure 1, Appendix 1). This report describes ecological communities, determines the presence of protected species or their habitats, and locates jurisdictional wetlands and waters of the United States in and adjacent to the project property. Recommendations are made concerning impacts to potential protected spedes habitats, jurisdictional wetlands,. and waters of the United States. Consideration of impacts to protected species and wetlands is required under the North Carolina Solid Waste Management Rules (15A NCAC 13B). Rare and protected species include species protected by state and federal laws, as well as rare species that, although not legally protected, are of concern to listing agencies and members of the scientific community. Legally protected species include animals listed as Endangered, Threatened, Special Concern, or Extirpated by the North Carolina Wildlife Resources Commission (NCWRC); plants listed as Endangered, Threatened, or Special Concern by the North Carolina Department of Agriculture (NCDA); and plants and animals listed as Endangered or Threatened by the U.S. Fish and Wildlife Service (FWS 1989, 1990a, 1990b). Rare species include Candidates for federal listing by FWS and those listed as Candidates or as Significantly Rare by the North Carolina Natural Heritage Program (NCNHP). Efforts to accommodate these species found on a project area are encouraged but not required; such efforts help preserve a rare species before it becomes critically imperiled and legally protected. Wetlands are defined by the U.S. Army Corps of Engineers (COE) and the U.S. Environmental Protection Agency as "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (Environmental Laboratory 1987). Areas that do not meet the criteria for wetlands, but that hold impounded or running water during some or all of the year, are termed waters of the United States. This term applies to such features as lakes, ponds, rivers, and perennial and intermittent streams. 2.0 MATERIALS AND METHODS 2.1 Literature Review and Records Search Methods. A literature and map review was performed for the study area, consisting of an examination of soil survey maps (Goldston 1937), the U.S. Geological Survey topographic map (USGS 1970), a National Wetlands Inventory (NWI) map (FWS 1994a), and aerial photographs of the project area obtained from the Surry County Mapping Department. Lists of protected plant and animal species potentially occurring on the project area and their habitat requirements were obtained from NCNHP (1995) and FWS (1995). Additional information on plant and animal species identification, rare and protected species identification, species distribution, and habitat requirements was compiled from a number of sources, including field guides and distribution atlases: Conant and Collins (190,1), Duncan and Foote (1975), Fernald (1987), Godfrey and Wooten (1979, 1981), Martof et al. (1989), Page and Burr (1991), Radford et al. (1968), Scott (1988), and FWS (1994b). 2.2 Field Survey A pedestrian reconnaissance of the entire F.roject area was performed on August 8-11, 1995 by William R. Nethery, Senior Environmental Scientist, and C. Fred Davis, Environmental Scientist. Habitats were evaluated and a determination was made of the potential for each habitat on the site to support protected species as well as state Significantly Rare and state and federal Candidate species. Appropriate habitats were searched thoroughly for protected species. No special sampling (e.g. mist netting for bats or birds, mammal trapping, or sampling streams for fish) was performed for these studies. The field methodology for the wetlands reconnaissance followed the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) an d subsequent guidance (Department of the Army 1992). An assessment of the three mandatory wetland criteria, vegetation, soils, and hydrology, was performed for potential jurisdictional wetland areas, and observations of wetland criteria throughout the project area were noted. Hydric soils were confirmed with Soil Conservation Service (SCS 1991). Soil color was determined with Munsell (1992) and plant indicator status was verified with Reed (1988). The approximate locations of wetland areas and habitats were drawn on field maps during the investigation, and representative photographs were taken. 3.0 RESULTS AND DISCUSSION 3.1 General Project Area Description The project area is in the upper Piedmont region in northwestern North Carolina. The geology of the region includes clastic metasedimentary rock and mafic and felsic metavolcanic rock of the Ashe Metamorphic Suite (N.C. Division of Land Resources, 1994). The project area is drained by the Ararat River and its tributaries and Stoney Creek. Elevations range from approximately 900 ft above mean sea level along the river to over 1,100 ft on a ridge in the northwest corner of the site (USGS 1970). Soil survey maps indicate that ridges and upper slopes on the site contain Cecil clay loam and Cecil clay loam, steep phase, which are well-drained soils. The Ararat River floodplain is mapped as Congaree silt loam, which is also well drained. The project area is composed mainly of agricultural fields on ridges and forests in drainages. Figures illustrating the project property are contained in Appendix 1. 3.2 Description of Ecological Communities Seven ecological communities exist in and adjacent to the study area: Agricultural/Field, Disturbed Hardwood-Pine Forest, Pine Forest, Oak-Hickory Forest, Mixed Mesic Hardwood Forest, Chestnut Oak Forest, and Aquatic Habitat. Several ravines and slopes in the project property contain mature, relatively natural, ecological communities. Upper slopes, ridges, and some drainages contain agricultural fields or forests recently disturbed by timber harvesting or storm damage. All ecological communities in the project property appear to have a history of cattle grazing. The approximate boundaries of ecological communities are depicted in Figure 2. Scientific names of common plant species found in the project area are contained in Appendix 2. The Agricultural/Field community occurs on ridges and upper slopes that have been farmed or pastured for over twenty years or cleared for pasture more recently. Most pastures and fields are currently fallow and contain fescue, Timothy grass and other planted pasture species,.with invasive species beginning to colonize the fields (Figure 3). Native species colonizing the fields include blackberry, a nightshade (Figure 4), meadowbeauty (Figure 5), ladies' tresses (Figure 6), sensitive brier (Figure 7), Joe-pye- weed (Figure S), diodia, asters, St. John's-wort, rabbit tobacco, boneset, and Virginia pine (Figure 9). Animals observed in this community include eastern meadowlark, eastern bluebird, and mourning dove. The Disturbed Hardwood-Pine Forest community occurs on slopes and ridge tops in the project area that have been recently harvested and/or severely disturbed by Hurricane Hugo. Residual mature hardwoods, including oak, hickory, and sourwood, are scattered. in this community, with abundant regeneration of hardwoods and some pine. Japanese honeysuckle and grape have dominated some areas of this community. The Pine Forest community occurs on several upper slopes and ridges that have not been harvested or cleared for agriculture recently. Virginia pine dominates the canopy, with occasional hardwoods in the subcanopy. Virginia pine is particularly susceptible to windthrow, and impacts from Hurricane Hugo are readily evident in this community (Figure 10). The understory contains southern red oak, white oak, mockernut hickory, sourwood, dogwood,. Amercan holly, blueberry, strawberry bush, catbrier, grape, Japanese honeysuckle, pipsessewa, and occasionally pink ladyslipper (Figure 11). Animals observed in the Pine Forest community include Carolina chickadee, tufted titmouse, American crow, and fence lizard (Figure 12). The Oak-Hickory Forest community occurs on several drier, exposed and upper slopes in the project area. The canopy is dominated by white oak, southern red oak, chestnut oak, pignut hickory, and mockernut hickory (Figure 13). The understory contains sourwood, red maple, American holly, grape, blueberry, Japanese honeysuckle, rattlesnake plantain (Figure 14), and cranefly orchid. Several mushroom species were observed in this and the other hardwood forest communities (Figure 15). Animals observed in this community include Fowler's toad (Figure 16), bluejay, and American crow. The Mixed Mesic Hardwood Forest community occurs in small coves and on lower slopes in ravines (Figure 17). The upper canopy includes white oak, tulip poplar, northern red oak, chestnut oak, American beech, sourwood, yellow birch, hickory species, and occasional Virginia pines. The understory contains sugar maple; dogwood, silverbells, musclewood, rhododendron, mountain laurel, azalea, black cherry, strawberry bush, umbrella magnolia, Fraser magnolia, witch-hazel, pawpaw, shadbush, and hazelnut. The ground layer vegetation was relatively diverse and included poison ivy, rattlesnake plantain, cranefly orchid, solomon's seal, liverleaf, perfoliate bellwort, wild hydrangea, bloodroot, Indian cucumber, beggar-lice, wild ginger, violet species, southern lady fern, christmas fern, virginia creeper, wild yam, maidenhair fern, jack-in- the-pulpit, foam flower, and lopseed. Animals observbd in this community include common toads, yellow-shafted flicker, eastern box turtle, and tufted titmouse. Several eastern box turtles found in this community were very ill with tumors and/or eye and respiratory infections (Figures 18 and 19). The Chestnut Oak Forest community is present on steep slopes above Stoney Creek and on upper slopes of ravines. It is dominated by chestnut oak, with white oak, tulip poplar, yellow birch, Fraser magnolia, Virginia pine, sourwood, and red maple present in the canopy and subcanopy. The Chesnut Oak Forest understory includes silverbells, mountain laurel, rhododendron, Fraser magnolia, blueberry, and tree saplings. Ground layer vegetation includes grape, blueberry, galax, Christmas fern, Indian cucumber, rattlesnake plantain, cranefly orchid, and wild ginger. The understory is a dense heath slick in some places (Figure 20) and relatively open in other areas (Figure 21). At the base of -the slope along the creek in this community, giant cane, yellowroot, partridgeberry, southern lady fern, and poison ivy are present in addition to galax, Christmas fern, and other ground layer plants under a heath canopy with scattered chestnut oak (Figure 22). The only animals observed in this community were tufted titmouse and one sick eastern box turtle. Aquatic Habitat communities in the project area include unnamed intermittent and spring-fed perennial streams, Stoney Creek, and the Ararat River. The intermittent stream channels are approximately 1-3 feet wide with one foot banks and sandy gravel and cobble bottoms (Figure 23). The spring-fed perennial streams are 2-6 feet wide with 1-4 foot banks and substrata of gravel, cobble, sand, and silt. Stoney Creek is approximately 15-20 feet wide witli varying bank heights and contains a rock bottom with occasional boulders (Figure 24), or gravel, cobble and boulder bottom (Figure 25), with a thin silt layer in some places (Figure 26). The Ararat River, approximately 25-40 feet wide, contains a gravel, cobble, and boulder bottom with moderate sand and silt layers. The bank of the Ararat River is approximately ten feet high in the project area but is not well defined along very steep slopes across the river from the project property. Southern mountain dusky salamanders were observed in the spring-fed perennial stream transecting the property (Figure 27). Chub nests exist in Stoney Creek, but no fish were observed in the creek. Very few aquatic insects were observed in any Aquatic Habitat in the project area. 3.3 Protected Species Assessment Protected species occurrence lists from NCNHP (1995) and FWS (1995) indicate that seven state or federally protected plant and animal species are known from Surry County. Protected species information is summarized in Appendices 3 and 4. Habitat or marginal habitat is present in or adjacent to the project property for four protected animal species and one protected plant species. 3.3.1 Animals. The NCNHP (1995) an FWS (1995) rare and protected animal species lists serve as the,basis for this protected animal study. One state and federally protected animal species and five state protected animal species potentially occur in Surry County. Marginal habitat occurs in the project corridor for four state protected animal species. No state or federally protected animal species were observed during the field surveys. The Mixed Mesic Hardwood Forest and Chestnut Oak Forest communities in the project area contain marginal habitat for the state Threatened Wehrle's salamander and the state Special Concern mole salamander and four-toed salamander. Stoney Creek and the Ararat River may be suitable for the brook floater. No evidence of these species was observed .in the project area. More specialized surveys by local experts would be necessary to definitively determine the presence of these species in the project property. One state Significantly Rare and/or federal Candidate animal species, common raven, potentially occurs in Surry County. The project area does not contain suitable habitat for this species, although it could forage in the area. Common raven was not observed in the project area. 3.3.2 Plants. The NCNHP (1995) and FWS (1995) lists of rare or protected plant species potentially occurring in the project area serve as the basis for the protected plant study. One state protected plant species potentially occurs in Surry County. Twelve federal Candidate and'/or state Candidate or Significantly Rare plant species are also known from Surry County. Habitat is present in the project area for one state and federally protected plant species and several rare, unprotected plant species. Habitat is present for one protected plant species, the state and federally Endangered small-whorled pogonia, in Mixed Mesic Hardwood Forest and Chestnut Oak Forest communities. This species was not observed in the project property, but the flowering season of this plant is in spring. A spring survey for small-whorled pogonia would be required to definitively determine its presence in the project property. Several state Significantly Rare or Candidate and/or federal Candidate plant species potentially occur in Surry County. Habitat or marginal habitat occurs in the project area for three state Significantly Rare or Candidate and/or federal Candidate plant species. None of these species was observed in the project area. 3.4 Jurisdictional Wetlands Assessment No hydric soils are mapped in the projct property. The National Wetland Inventory map (FWS 1994) indicates the presence of riverine unconsolidated bottom (waters) and intermittent streams in the project property. One very small jurisdictional wetland was found in the northwest corner of the project area. The approximate location of this wetland is shown in Figure 2. This is a small seepage wetland with sparse vegetation that drains into Stoney Creek A portion of this wetland had been excavated to create a watering hole for cattle (Figure 28). The wetland is overhtulg by rhododendron and red maple but contains no trees. The sparse ground layer contains microstegium, jewelweed, clearweed, duck-potato, smartweeds, soft rush, and sedge species. Wetland hydrology indicators in this location include saturation to the surface, drainage patterns, and water-stained leaves. Soils exhibit hydric characteristics, including low chroma matrices and mottling. Waters of the United States exist in and adjacent to the project property in several unnamed intermittent and perennial streams, Stoney Creek, and the Ararat River. Intermittent streams are 1-3 feet wide, and smaller perennial streams are 2-6 feet wide. Stoney Creek adjacent to the project property is 20-25 feet wide, and the Ararat River adjacent to the project property is approximately 30-40 feet wide. Stoney Creek contains small amounts of riffle-and-pool complex, a special aquatic site. 4.0 SUMMARY AND RECOMMENDATIONS A protected species survey and wetlands delineation were conducted in the proposed Surry County Landfill expansion project area. The project property consists of approximately 115 acres between the Ararat River and Stoney Creek southeast of Mount Airy, North Carolina. This survey addresses protected species and wetlands concerns as required by state and federal laws. The project area contains seven ecological communities: Agricultural /Field, Disturbed Hardwood-Pine Forest, Pine Forest, Oak-Hickory Forest, Mixed Mesic Hardwood Forest, Chestnut Oak Forest, and Aquatic Habitat. Tvvo hardwood forest communities, Mixed Mesic 1ardwood 1sorest and Chestnut Oak f=orest, are mature and relatively natural ecological communities. The other ecological communities in the project property were disturbed by timber harvesting or other activities or Hurricane Hugo. Five state or federally protected animal species and one state and federally protected plant species potentially occur in Surry County. Habitat or marginal habitat is present in and adjacent to the project property for four state protected animal species: brook floater, mole salamander, four-toed salamander, and Wehrle's salamander. Habitat is present for the one state and federally protected plant species, small-whorled pogonia, and several state Candidate or Significantly Rare, or federal Candidate plant species. No habitat or marginal habitat is present in the project area for any other state or federally protected animal or plant species, and no protected animal or plant species were observed during our field investigations. We recommend avoidance of impacts to Aquatic Habitat and natural communities on slopes and in ravines that are suitable to support protected species on the project property. Avoidance of these communities will be practicable where these communities occur within the legally required buffer zones around the proposed landfill expansion. Where avoidance of impacts to ravines is not practicable, particularly to the drainage area in the central portion of the project property, we recommend a spring survey for small-whorled pogonia and an intensive survey for protected salamanders by a locally expert salamander biologist. We recommend avoiding impacts to the wetland and waters of the United States in the project property to the extent practicable. Avoidance will be practicable in the wetland and waters in the required buffer zones. Permits will be required from the COE under Section 404 of the Clean Water Act if fill is to be placed in any waters of the United States, including intermittent streams. Also, sedimentation and erosion control measures must be taken to protect waters that are not directly impacted by construction. 5.0 REFERENCES Conant, Roger, and Joseph T. Collins. 1991.

Box 97 ES COtUff' Garner, NC 27529 SUBJECT: Rare Species, High Quality Natural Communities, and Significant Natural Areas in the Proposed Surry County Landfill Project Area, Surry County, North Carolina Dear Mr. Sullivan: The North Carolina Natural Heritage Program does not have records of known rare species, high quality natural communities, or significant natural areas occurring at or within a 1-mile radius of the Surry County Landfill project area. To our knowledge, this project area has not been systematically inventoried and we cannot definitively state that rare species or significant natural areas do not occur there. Enclosed is a list of rare species that are known to occur in Surry County. If suitable habitat for any of these species occurs in the project area, then those species may be present at the project site. If it is necessary to be certain that this site does not contain rare species, a field survey would need to be conducted. Please contact me at the address below or call me at (919) 733-7701 if you have any questions or need further information. Sincerely, Inge Smith Information Specialist Natural Heritage Program /iks Enclosures NATURAL HERITAGE ELEMENTS AND SPECIES STATUS CODES The attached output from the N.C. Natural Heritage Program database is a listing of the elements (rare species, geologic features, natural communities, and special animal habitats) known to occur in your geographic area of interest. The information on this printout is compiled from a variety of sources, including field surveys, museums and herbaria, literature, and personal communications. The database is dynamic, with new records being added and old records being revised as we receive new information. The enclosed list cannot be considered a definitive record of natural heritage elements, and it should not be considered a substitute for field surveys. When this information is used in any document, we request that the printout date be given and that the Natural Heritage Program be credited- This cover sheet explains the four columns of status codes that are given on the right-hand side of the printout. STATE PROTECTION CODE STATUS CODE STATUS E Endangered SR Significantly Rare T Threatened V Vulnerable Sc Special Concern UNR Undetermined C Candidate EX Extirpated P Proposed (E, T, or C) Plant statuses are determined by the Plant Conservation Program (N.C. Dept. of Agriculture) and the Natural Heritage Program (N.C. Dept. of Environment, Health, and Natural Resources). E, T, and SC species are protected by state law (the Plant Vrotection and Conservation Act, 1979); C and SR designations indicate rarity and the need for population monitoring and conservation action, as determined by the Plant Conservation and Natural Heritage Programs. Animal statuses that indicate state protection (E, T, and SC) are published in "Endangered Wildlife of North Carolina", March 16, 1992, N.C. Nongame and Endangered Wildlife Program. The Significantly Rare, Undetermined, Vulnerable and Extirpated statuses are (for the most part) Natural Heritage Program designations. They indicate rarity and the need for population monitoring and conservation action. FEDERAL PROTECTION The current federal status is listed in "Endangered and Threatened Wildlife and Plants, July 15, 1991 (50 CFR 17.11 & 17.12, Department of the Interior). Definitions are taken from the Endangered Species Act of 1973, as amended through the 100th Congress (1988), and the Federal Register, Part VIII, November 21, 1991 (50 CFR 17, Department of the Interior). CODE STATUS DEFINITION E Endangered A taxon which "is in danger of extinction throughout all or a significant portion of its range" T Threatened A taxon "which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range" P Proposed A taxon which has been proposed for official listing as endangered or threatened L Listed A taxon which has been officially listed as _ endangered or threatened C1 Category 1 A taxon which is under consideration, and for ("Candidate 1") which there is sufficient information to supn_ort listnQ C2 Category 2 A taxon which is under consideration, but for ("Candidate 2") which there is insufficient information to support listing 3A Category 3A A taxon which was formerly under consideration for ("Candidate 3A") listing, but for which there is "persuasive evidence of extinction" 3B Category 3B A taxon which was formerly under consideration for ("Candidate 3B") listing, but which current taxonomic understanding does not support as a distinct entity meeting the Endangered Species Act's definition of "species" 3C Category 3C A taxon formerly under consideration for listing, ("Candidate 3C") but which has been "proven to be more abundant or widespread than previously believed and/or (which is] not subject to any identifiable threat" GLOBAL AND STATE RANK These ranks are determined by The Nature Conservancy's system of measuring rarity and threat status. "Global" refers to worldwide and "State" to statewide. RANK DEFINITION GI Critically imperiled globally because of extreme rarity or otherwise very vulnerable to extinction throughout its range G2 Imperiled globally because of rarity or otherwise vulnerable to extinction throughout its range G3 Either very rare and local throughout its range, or found locally in a restricted area G4 Apparently secure globally, although it may be quite rare in parts of its range (especially at the periphery) G5 Demonstrably secure globally, although it may be quite rare in parts of its range (especially at the periphery) GH Of historical occurrence throughout its range GX Believed to be extinct throughout its range GU Possibly in peril but status uncertain; more information is needed G? Unranked, or rank uncertain _Q Of questionable taxonomic status T_ Status of subspecies or variety; the G rank refers to the species as a whole State rank codes follow the same definitions, except the words "in -the state" should be substituted for "globally" or "throughout its range." Also, there are four additional state ranks: RANK DEFINITION SR Reported from North Carolina, but without persuasive documentation _B Rank of the breeding population in North Carolina; used only for migratory species _N Rank of the non-breeding population in North Carolina; used only for migratory species Population is not of significant conservation concern; applies to transitory, migratory species -- 2/4/93 N.C.

Crow, Director JAN 24 1996 1 ,I 'Crs C0VNA We have received the final archaeological survey report for the above project from Dr. Gunn of Garrow & Associates, Inc. As noted in our letter of November 3, 1995, we concur with Dr. Gunn's recommendation that site 31 SR153 be tested to determine its eligibility for inclusion in the National Register of Historic Places. We have not yet received either the plans for the proposed landfill or the archaeological site form and location for the isolated find of the Palmer projectile point as requested. Please forward these as soon as possible. These comments are made in accord with G.S. 121-12(a) and Executive Order XVI.
