(TRANSFLO) Charlotte West Rail Terminal in Mecklenburg County,NC. The expansion is proposed to the south of the current terminal location and will therefore impact tributaries to the headwaters of Paw Creek. Paw Creek occurs within the Catawba River Basin. The Federally Endangered Carolina Heelsplitter(Lasmigona decorata)is listed by the US Fish and Wildlife Service(USFWS)as occurring in Mecklenburg County,NC. While extant populations of the Carolina Heelsplitter are not currently known from the Catawba River Basin in Mecklenburg County,there are several historical records known from late 19`h and early 20`h century collections housed in the Philadelphia Academy of Natural Sciences, including an individual from the Paw Creek drainage(Keferl 1991). In addition to the Carolina Heelsplitter,there are several other rare freshwater mussel species known to occur in Mecklenburg County,NC. These include the Carolina Creekshell(Villosa vaughaniana),Eastern Creekshell(V. delumbis), Creeper(Strophitus undulatus),and the Notched Rainbow(V. constricta). The Carolina Creekshell,Creeper,Notched Rainbow and Eastern Creekshell are considered Endangered(E),Threatened(T), Special Concern(SC)and Significantly Rare(SR)respectively,in North Carolina'. As such,ARCADIS,the primary environmental consultant for the project, contracted The Catena Group(Catena)to conduct freshwater mussel surveys for the proposed expansion. 2.0 TARGET FEDERALLY PROTECTED SPECIES DESCRIPTION (Carolina Heelsplitter) 3.1 Species Characteristics The Carolina Heelsplitter, originally described as Unio decoratus by(Lea 1852), synonymized with Lasmigona subviridis (Conrad 1835,Johnson 1970), and later separated as a distinct species y' (Clarke 1985), is a Federally Endangered freshwater mussel, historically known from several locations within the Catawba and Pee Dee River systems in North Carolina and the Pee Dee, Savannah,and the Saluda River systems in South Carolina. The Carolina Heelsplitter can reach a length of 118 mm,with a height of 68 mm and a width of 39 mm. Based on some specimens collected by Keferl and Shelley (1988) from three different streams and rivers,the mean length is 78 mm,the mean height is 43 mm and the mean width is 27 mm. The shell is an ovate trapezoid. The dorsal margin is straight and may end with a slight wing. The umbo is flattened. The beaks are depressed and project a little above the hinge line. The beak sculpture is double looped. The unsculptured shell can have a 1 North Carolina Endangered,Threatened and Special Concern species have legal protection status in North Carolina under the State Endangered Species Act administered and enforced by the North Carolina Wildlife Resources Commission.Species listed as Significantly Rare are not afforded any protection. Paw Creek Mussel Surveys April 2014 Catena Job#3351 1 yellowish,greenish or brownish periostracum. The Carolina Heelsplitter can have greenish or blackish rays. The lateral teeth may or may not be well developed; in most cases they are thin. The pseudo-cardinal teeth are lamellar and parallel to the dorsal margin,and there is a slight interdentum. The nacre varies from an iridescent white to a mottled pale orange. The shell's nacre is often pearly white to bluish white,grading to orange in the area of the umbo(Keferl 1991). The hinge teeth are well developed and heavy and the beak sculpture is double looped(Keferl and Shelly 1988). Morphologically,the shell of the Carolina Heelsplitter is very similar to the shell of the Green Floater(Clarke 1985),with the exception of a much larger size and thickness in the Carolina Heelsplitter(Keferl and Shelly 1988). Prior to collections in 1987 and 1990 by Keferl(1991),the Carolina Heelsplitter had not been collected in the 20'h century and was known only from shell characteristics. Because of its rarity, very little information of this species' biology, life history,and habitat requirements was known until very recently. Feeding strategy and reproductive cycle of the Carolina Heelsplitter have not been fully documented,but are likely similar to other native freshwater mussels(USFWS 1996). The feeding processes of freshwater mussels are specialized for the removal(filtering)of suspended microscopic food particles from the water column(Pennak 1989). Documented food sources for freshwater mussels include detritus,diatoms,phytoplankton,and zooplankton (USFWS 1996). Freshwater mussels have complex reproductive cycles,which include a larval stage(glochidium) that is an obligatory parasite on a fish. The glochidia develop into juvenile mussels and detach from the"fish host"and sink to the stream bottom where they continue to develop,provided suitable substrate and water conditions are available(USFWS 1996). McMahon and Bogan (200 1) and Pennak(1989) should be consulted for a general overview of freshwater mussel reproductive biology. Until recently,nothing was known about the host species(s) for the Carolina Heelsplitter (USFWS 1996,Bogan 2002). Starnes and Hogue(2005) identified the most likely fish host candidates(15 species)based on fish community surveys in occupied streams throughout the range of the Carolina Heelsplitter. Captive propagation efforts for this species had not been attempted in the past;however,due to the critical level of imperilment of the North Carolina populations,acting on recommendations from the NC Scientific Council on Mollusks,the NC Wildlife Resources Commission(NCWRC) funded a life history/captive propagation study, which allowed for salvage of individuals from the Goose/Duck and Sixmile Creek populations to be used in the study. A total of nine minnow species(Cyprinidae)were identified as suitable, and two sunfish species(Lepomis spp.)were identified as marginally suitable host species(Eads and Levine 2008,Eads et al.2010). All of these species may occur in habitat types known to be occupied by the Carolina Heelsplitter;however,"it is always possible that it may use a combination of fish host species and some may not be native to all streams inhabited by this mussel"(Starnes and Hogue 2005). Another member of the genus Lasmigona, the Green Floater (Lasmigona subviridis),perhaps a close relative to the Carolina Heelsplitter,has been documented to be capable of in situ early development with glochidia developing within the marsupium of the female(Barfield and Watters 1998), thus it is possible that the Carolina Heelsplitter may also be able to propagate by direct transformation. Paw Creek Mussel Surveys April 2014 Catena Job#3351 2 3.2 Distribution and Habitat Requirements Currently,the Carolina Heelsplitter has a very fragmented,relict distribution. Until recently, it was known to be surviving in only six streams and one small river(USFWS 1996);however, recent discoveries have increased the number of known populations to eleven: Pee Dee River Basin: 1. Duck Creek/Goose Creek-Mecklenburg/Union counties,NC 2. Flat Creek/Lynches River-Lancaster/Chesterfield/Kershaw counties, SC Catawba River Basin: 3. Sixmile Creek(Twelvemile Creek Subbasin)-Lancaster County, SC 4. Waxhaw Creek-Union County,NC and Lancaster County, SC 5. Cane Creek/Gills Creek-Lancaster County, SC 6. Fishing Creek Subbasin-Chester County, SC 7. Rocky Creek Subbasin(Bull Run Creek/UT Bull Run Creek/Beaverdam Creek-Chester County, SC Saluda River Basin: 8. Redbank Creek- Saluda County, SC 9. Halfway Swamp Creek-Greenwood/Saluda County, SC Savannah River Basin: 10. Little Stevens Creek/Mountain Creek/Sleepy Creek/Turkey Creek(Stevens Creek Subbasin) -Edgefield/McCormick counties, SC. 11. Cuffytown Creek(Stevens Creek Subbasin)-Greenwood/McCormick counties, SC All of these populations occur in stream reaches within the Piedmont Physiographic Province, particularly within two northeast trending lithostratigraphic belts of the Carolina Terrane,the Carolina Slate Belt and the Charlotte Belt. The Carolina Slate Belt is a band of greenschist facies metavolcanic rock formations positioned in the central and lower Piedmont province extending from south-central Virginia to extreme eastern Georgia(Howell 2005,Butler and Secor 1991). The Charlotte Belt extends from north central North Carolina to eastern Georgia and is comprised of amphibolite facies metavolcanic and metaplutonic rock(Howell 2005, Butler and Secor 1991). These hard formations strongly dictate the channel morphology and character of stream substrates where they intersect. Starnes and Hogue(2005)describe such reaches as"generally characterized by dark,often tilted,bedrock stream bottom with associated Paw Creek Mussel Surveys April 2014 Catena Job#3351 3 large and small rock rubble interspersed with pockets of sand, silt,and gravel." Habitat for this species has been reported from small to large streams and rivers as well as ponds. The ponds are believed to be millponds on some of the smaller streams within the species' historic range (Keferl 1991). Keferl and Shelly(1988) and Keferl(1991)reported that most individuals have been found along well-shaded streambanks with mud,muddy sand,or muddy gravel substrates; however,numerous individuals in several of the populations have been found in cobble and gravel dominated substrate in stream reaches intersecting the hard rock formations described above(T. W. Savidge personal observations). The stability of stream banks appears to be very important to this species(Keferl 1991). 3.3 Threats to Species The low numbers of individuals and the restricted range of each of the surviving populations make them extremely vulnerable to extirpation from a single catastrophic event or activity (USFWS 1996). The cumulative effects of several factors,including sedimentation,point and non-point discharge, and stream modification(impoundments, channelization,etc.)have contributed to the decline of this species throughout its range(USFWS 1996). Siltation resulting from improper sedimentation control of various land usage practices, including agriculture, forestry,and development activities,has been recognized as a major contributing factor to the degradation of mussel populations(USFWS 1996). Siltation has been documented to be extremely detrimental to mussel populations by degrading substrate and water quality, increasing potential exposure to other pollutants,and by direct smothering of mussels (Ellis 1936,Markings and Bills 1979). Sediment accumulations of less than one inch have been shown to cause high mortality in most mussel species(Ellis 1936). Sewage treatment effluent has been documented to significantly affect the diversity and abundance of mussel fauna(Goudreau et al. 1988). Goudreau et al. (1988)found that recovery of mussel populations might not occur for up to two miles below points of chlorinated sewage effluent. The impact of impoundments on freshwater mussels has been well-documented(USFWS 1992a, Neves 1993). Dam construction transforms lotic habitats into lentic habitats,which results in changes within aquatic community composition. Muscle Shoals on the Tennessee River in northern Alabama,once the richest site for naiads(mussels) in the world, is now at the bottom of Wilson Reservoir and covered with 19 feet of muck(USFWS 1992b). Large portions of all of the river basins within the Carolina Heelsplitter's range have been impounded; this is believed to be a major factor contributing to the species decline(USFWS 1996). The introduction of exotic species such as the Asian Clam(Corbicula fluminea)and Zebra Mussel(Dreissena polymorpha)has also been shown to pose significant threats to native freshwater mussels. The Asian Clam is now established in most of the major river systems in the United States(Fuller and Powell 1973); including those streams still supporting surviving populations of the Carolina Heelsplitter(USFWS 1996). Concern has been raised over competitive interactions for space, food,and oxygen with this species and native mussels, possibly at the juvenile stages(Neves and Widlack 1987,Alderman 1995).The Zebra Mussel is not known from any waterbodies supporting the Carolina Heelsplitter(USFWS 1996). Paw Creek Mussel Surveys April 2014 Catena Job#3351 4 3.0 SURVEY EFFORTS ARCADIS identified and named three perennial streams within the project study area; SA, SB, and SC,that could potentially provide habitat for the Carolina Heelsplitter. These three streams were evaluated for appropriate habitat and surveyed as determined necessary during the field visit. The efforts were conducted by Tom Dickinson(NC)WRC permit 14-ES00343 and Federal permit TE102324-0)and Chris Sheats of Catena with assistance from Bob Lepsic of ARCADIS on April 18,2014. The habitat assessment and survey reaches are depicted in Figure 1. 3.1 Methodology Visual surveys were conducted using glass bottom view buckets(bathyscopes). Tactile methods were employed,particularly in streambanks and under loose rocks. All areas of appropriate habitat were searched,concentrating on the stable habitats preferred by the target species. The survey team spread out across the creek into survey lanes and proceeded upstream to the vicinity of the terminal yard or to the streams culvert outlets. 4.0 RESULTS No freshwater mollusks were observed during the survey efforts. Habitat conditions and site specific survey results are provided for each survey segment below. 4.1 Stream SA Stream SA(Appendix A,Photo 1)was approximately 1 meter wide with banks ranging from 0- 1 meter high. Substrate consisted primarily of silt and fine sand. A habitat assessment was conducted by walking the stream within the study area. This evaluation determined that the stream was limiting to freshwater mussel colonization due to its small size and that full survey efforts were unnecessary. 4.2 Stream SB Stream SB (Photo 2)ranged from 2-4 meters wide with generally unstable 0.5-2 meter high banks. Habitat consisted of a series of riffle,run,and pool with angular cobble,boulder,and occasional bedrock outcrops in higher gradient areas and silt, sand,and gravel in pools, interstitial spaces,and on depositional bars. The stream exhibited significant scouring,often to saprolite,where rocky substrates were not present to provide grade control. Surrounding land consisted of mature hardwood forest,residential development,and sewerline in addition to the terminal yard at the upstream reach extent. Surveys were conducted for 3.0 person hours,during which no freshwater mollusks were observed. Aquatic life observed consisted of crayfish and amphibians.

Habitat consisted of a series of riffle,run, and pool that were dominated by cobble,boulder,and gravel in higher gradient areas and by silt, sand,and gravel in pools,interstitial spaces,and on depositional bars. Surrounding land consisted of mature hardwood forest and residential development. Surveys were conducted for 1.4 person hours,during which no freshwater mollusks were observed. Aquatic life observed consisted only of crayfish and amphibians. 5.0 CONCLUSIONS The survey results indicate that the streams evaluated do not support a freshwater mussel fauna. Physical habitat was consistent with areas where freshwater mussels are found; however, conditions were degraded by upstream and surrounding land uses. Additionally,these streams are likely subject to frequent drought conditions due to their headwater position which can limit fish and mussel colonization. Recent surveys conducted in the Paw Creek watershed at downstream locations also did not locate a freshwater mussel fauna(Catena 2008). The Carolina Heelsplitter was not found during these surveys. Given these and previous survey results it appears unlikely that the Carolina Heelsplitter currently occurs in Paw Creek watershed. Based on the information presented here it can be concluded that the proposed project will have "No Effect"on the Carolina Heelsplitter.

improvements to develop a rail yard and supporting infrastructure. The project site is located at the CSX Way cul-de-sac in Charlotte, NC. Project property includes 53.80 acres zoned for industrial use. The site consists of mostly gentle to steep slopes with some generally flat areas that primarily drain South. There are minimal impervious areas on site. For calculation purposes,existing impervious was considered 0 acres. The project will disturb 18.50 acres during construction and will include removal of vegetation, installation of erosion control measures,grading,construction of a rail yard,utility building,and supporting infrastructure. Impervious area added during construction will result in a net increase of 5.78 acres over preconstruction conditions. Construction is expected to begin in November/December 2016. The anticipated duration of construction is approximately 1 year. For the purposes of this project,a structural stormwater BMP has been designed to be installed to treat runoff from new built upon areas. The BMP for this site will receive flows from a drainage area of 7.65 acres of runoff.The remaining drainage area will remain pervious and has a hydrograph entitled 'Undetained'. Hydrograph 5,'Total Post Out'is a combined hydrograph that combines the wet pond hydrograph with the undetained Hydrograph. The structural BMP chosen for this site is a wet detention basin designed for 85%TSS and 70%total phosphorus removal based on City of Charlotte storm water requirements. Waters discharge south to an existing stream. All new impervious areas on site will be treated by the basin. The table below displays pre and post construction peak discharges.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation,are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D)and three dual classes(A/D, B/D, and C/D).The groups are defined as follows: Group A. Soils having a high infiltration rate(low runoff potential)when thoroughly wet.These consist mainly of deep,well drained to excessively drained sands or gravelly sands.These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet.These consist chiefly of moderately deep or deep,moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet.These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture.These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate(high runoff potential)when thoroughly wet.These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface,and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group(A/D, B/D, or C/D),the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.
