HDR is working with Duke Energy Carolinas, LLC to prepare a Comprehensive Site
Assessment for the above-referenced site (see attached site map for project
location). The North Carolina Department of Environment and Natural Resources
Guidelines for Performing Screening Level Ecological Risk Assessments require
identification of certain natural and cultural resources and sensitive environments.
Based on this requirement, we are requesting the following:

1. Are there any federally listed threatened, endangered or candidate species
(plant or animal), or critical habitat within the vicinity of this project?

2. Do any sensitive environmental areas exist adjacent to or within ½ mile of
the site (e.g., Federal and State parks, National and State monuments,
wetlands, other areas that provide unique and often protected habitat for
wildlife species-these areas are typically used during critical life stages such
as breeding, hatching, rearing of young and overwintering)?

3. Are any wetland areas such as marshes or swamps on or adjacent to the
site? (Wetlands are defined in 40 CFR §232.2 as “Areas inundated or
saturated by surface or groundwater at a frequency and duration sufficient to
support, and that under normal circumstances does support, a prevalence of
vegetation typically adapted for life in saturated soil conditions.”)

4. Does the site serve or potentially serve as a habitat, foraging area or refuge
by rare, threatened, endangered, candidate and/or proposed species (plants
or animals), or any otherwise protected species?

5. Is the site potentially used as a breeding, roosting or feeding area by
migratory bird species and if so, which ones?

6. Is the site used by any ecologically, recreationally or commercially important
species?

7. Are there any areas on or within ½ mile that is owned or used by local
tribes?

RE: Duke Energy – Dan River Steam Station
524 South Edgewood Road, Eden, Rockingham County, North Carolina

Dear Ms. Voyce:

Thank you for the opportunity to provide information from the North Carolina Natural Heritage Program
(NCNHP) database for the proposed project referenced above. Our office received Geographic
Information System (GIS) data for the proposed project area from Carol Zurlo, Project Scientist with HDR
Engineering, Inc., on May 26, 2015. Based on the proposed project area as submitted, the NCNHP
database does show records for rare species and a natural area within/adjacent to the project area.

Attached are tables showing records from the NCNHP database for element occurrences (rare species
and natural communities), natural areas, and conservation/managed areas that have been documented
within/adjacent to the project area and records documented within a one-mile radius of the project
area. Also attached is a map that shows natural heritage resources documented within/adjacent to the
project area and within one mile of the project area. The locations of natural areas and conservation/
managed areas may be viewed by accessing the Natural Heritage Data Explorer online map viewer, or by
downloading and using GIS data; both options are available from the NCNHP Data Services webpage
(see www.ncnhp.org).

Please note that occurrences of rare species documented within one mile of the proposed project area
increase the likelihood that these species may be present within the project area if suitable habitat
exists. The use of Natural Heritage Program data should not be substituted for actual field surveys if
needed, particularly if the project area contains documented occurrences or suitable habitat for rare
species. If rare species are found during field surveys, the NCNHP would appreciate receiving this
information so that we may update our database.

Thank you for your inquiry, and please feel free to contact me at [e-mail] or 919-
707-8629 if you have questions or additional information is needed.

Sincerely,
Allison Schwarz Weakley, Conservation Planner

Dear Ms. Voyce:

Thank you for your letter of May 19, 2015, concerning the above project. We have reviewed the information
submitted and offer the following comments.

There are no recorded archaeological sites located within the ash basins or steam station, but there are four
archaeological sites within about a half mile of your project area:

31RK1 (Lower Sauratown) is a Native American village site containing intact subsurface features. It is
located in the floodplain on the south side of the Dan River. This site is currently listed in the
National Register of Historic Places.
31RK5 (Powerplant Site) is a Native American village site containing intact subsurface features. It is
located in the floodplain on the south side of the Dan River. Although not currently listed in
the National Register of Historic Places, it is eligible for such listing.
31RK33 (Sauratown Plantation) is a late 18th – early 19th century domestic structure with an
archaeological component. It is located on a hilltop south of the Dan River. The standing
structure is currently listed in the National Register of Historic Places.
31RK61 is a Native American site located within the floodplain on the south side of the Dan River.
Little is known about this site except that burials washed out of this area during the flood of
1974. No additional investigations have been undertaken, but this site is likely similar to sites
31RK1 and 31RK5.

If any of these sites are to be affected by your proposed project, please forward project plans to us for our
review and comment.

The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the
Advisory Council on Historic Preservation’s Regulations for Compliance with Section 106 codified at 36 CFR
Part 800.

Thank you for your cooperation and consideration. If you have questions concerning the above comment,
contact Renee Gledhill-Earley, environmental review coordinator, at 919-807-6579 or

Subject: Request for Information for Dan River Steam Station, 524 S. Edgewood Road, Eden,
Rockingham County, North Carolina.

Dear Ms. Voyce:

Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the
subject information. Our comments are provided in accordance with provisions of the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667e) and North Carolina General Statutes
(G.S. 113-131 et seq.).

The site drains to Dan River in the Roanoke River basin. A request for information has been made
regarding the following natural and cultural resources, and sensitive environments.

1. Are there any federally listed threatened, endangered or candidate species (plant or animal), or
critical habitat within the vicinity of this project?
There are records for the federal and state endangered Roanoke logperch (Percina rex) in the Dan
River watershed. In addition, the U.S. Fish and Wildlife Service recently listed the Northern
long-eared bat (Myotis septentrionalis) as threatened under the Endangered Species Act. We
suggest contacting the U.S. Fish and Wildlife Service at [phone] regarding this species
and any other federally listed species or critical habitat within the vicinity of the site.
There are records for the federal species of concern and state endangered green floater
(Lasmigona subviridis), the federal species of concern and state significantly rare Roanoke bass
(Ambloplites cavifrons), the state threatened bigeye jumprock (Moxostoma ariommum), and the
state significantly rare Roanoke hogsucker (Hypentelium roanokense) and quillback (Carpoides
cyprinus) in the Dan River watershed. In addition, there are historical records for the state
threatened Jacob’s ladder (Polemonium reptans var. reptans), the state significantly rare coppery
emerald (Somatochlora georgiana), and the state significantly rare – throughout glade wild
quinine (Parthenium auriculatum) near the site.

June 19, 2015
Dan River Steam Station

Although we do not have any records for a federal or state listed species on the site, this does not
preclude the presence of a listed species on or adjacent to the site. It simply may mean the site
has not been surveyed. An on-site survey is the only definitive means to determine whether a
listed species is present on the site.
2. Do any sensitive environmental areas exist adjacent to or within ½ mile of the site (e.g.,
Federal and State parks, National and State monuments, wetlands, other areas that provide
unique and often protected habitat for wildlife species-these areas are typically used during
critical life stages such as breeding, hatching, rearing of young and overwintering)?
The Natural Heritage Natural Area – ROA/Dan River Aquatic Habitat – is located within ½ mile
of the site.
3. Are any wetland areas such as marshes or swamps on or adjacent to the site? (Wetlands are
defined in 40 CFR §232.2 as “Areas inundated or saturated by surface or groundwater at a
frequency and duration sufficient to support, and that under normal circumstances does
support, a prevalence of vegetation typically adapted for life in saturated soil conditions.”)
Unknown; we do not have any data regarding whether there are any wetland areas on or adjacent
to the site. Although USGS topographic maps and National Wetlands Inventory (NWI) maps
provide a general overview of stream and wetland resources, these should not be used to
determine whether streams or wetlands are present on the site. Wetlands and streams within the
site boundaries should be identified through on-site surveys. If wetlands and/or streams will be
impacted by any construction activities, then the project should be coordinated with the U.S.
Army Corps of Engineers and the N.C. Division of Water Resources.
4. Does the site serve or potentially serve as a habitat, foraging area or refuge by rare, threatened,
endangered, candidate and/or proposed species (plants or animals), or any otherwise protected
species?
Unknown; we do not have any data regarding whether the site serves as habitat for listed aquatic
or terrestrial wildlife species. We do not have any information regarding whether the site serves
as habitat for listed plant species; this is not within our area of expertise or purview.
5. Is the site potentially used as a breeding, roosting or feeding area by migratory bird species and
if so, which ones?
Unknown; we do not have any data regarding whether the site is used by migratory bird species.
6. Is the site used by any ecologically, recreationally or commercially important species?
Unknown; we do not have any data regarding whether the site is used by any ecologically,
recreationally, or commercially important aquatic species. However, there is recreational fishing
in the Dan River. Recreational aquatic species include: largemouth bass, catfish, and sunfish. It
is likely the site is too industrialized to support any ecologically, recreationally or commercially
important terrestrial wildlife species. However, raccoon, opossum, skunk, white-tailed deer,
coyotes, and other species commonly found throughout the Northern Piedmont region may be
found on the site. Recreationally important wildlife species in the vicinity of the site include, but
are not limited to: bear, white-tailed deer, beaver, mink, muskrat, nutria, otter, skunk, weasel,
bobcat, opossum, raccoon, fox, rabbit, squirrel, various species of wild ducks and geese, quail,
and wild turkey.
7. Are there any areas on or within ½ mile that is owned or used by local tribes?
We do not have any information regarding local tribes in the area ; this is not within our purview.

runoff (including runoff from the coal pile), miscellaneous equipment, cooling water, powerhouse
floor drains, sanitary waste effluent, station yard drainage sump, and boiler chemical cleaning wastes.
The coal ash was historically sluiced to the southwest corner of the Primary Cell on a variable basis
(i.e., dependent on the steam station operation) via sluice pipes.
Flow is routed from the Primary Cell to the Secondary Cell through a concrete discharge tower.
Effluent from the Secondary Cell is routed to the Dan River via a concrete discharge tower located in
the Secondary Cell. The water surface in both the Primary and Secondary Cells is controlled by the
use of stop logs.

III.C Wetland Habitats

Are any wetland 1 areas such as marshes or swamps on or adjacent to the site?

☒ Yes ☐ No

If yes, indicate the wetland area on the attached site map and answer the following questions regarding the
wetland area. If more than one wetland area is present on or adjacent to the site, make additional copies of
the following questions and fill out one for each individual wetland area. Distinguish between wetland
areas by using names or other designations (such as location). Clearly identify each area on the site map.
Also, obtain and attach a National Wetlands Inventory Map (or maps) to illustrate each wetland area.

Identify the sources of the observations and information (e.g., National Wetland Inventory, Federal or
State Agency, USGS topographic maps) used to make the determination whether or not wetland areas are
present.
Wetland areas were identified in the field by AMEC and HDR’s Professional Wetland Scientist.

If no wetland areas are present, proceed to Section III.D: Sensitive Environments and Receptors.

1 Wetlands are defined in 40 CFR §232.2 as “ Areas inundated or saturated by surface or groundwater at a frequency and duration
sufficient to support, and that under normal circumstances does support, a prevalence of vegetation typically adapted for life in
saturated soil conditions.” Examples of typical wetlands plants include: cattails, cordgrass, willows and cypress trees. National
wetland inventory maps may be available at http:\\nwi.fws.gov. Additional information on wetland delineation criteria is also
available from the Army Corps of Engineers.

III.D. Sensitive Environments and Receptors

1. Do any other potentially sensitive environmental areas 2 exist adjacent to or within one-half mile of the
site? If yes, list these areas and provide the source(s) of information used to identify sensitive areas. Do
not answer “no” without confirmation from the U.S. Fish and Wildlife Service and other appropriate
agencies. See Table 1 for a list of contacts.
NCNHP and NCWRC recorded revealed that a natural area (Dan River Aquatic Habitat is located
within ½ mile of the site boundary.

2. Are any areas on or near (i.e., within one-half mile) the site owned or used by local tribes? If yes,
describe.
No

3. Does the site serve or potentially serve as a habitat, foraging area or refuge by rare, threatened,
endangered, candidate and/or proposed species (plants or animals), or any otherwise protected species?
If yes, identify species. This information should be obtained from the U.S. Fish and Wildlife Service
and other appropriate agencies. See Table 1 for a list of contacts.
HDR obtained and reviewed an updated U.S. Fish and Wildlife Services (USFWS) protected species
list to determine whether rare, threatened, endangered, candidate and/or proposed plant or animal
species have the potential to occur within the site. The existing power line clearings and woodland
edges and openings are potential habitat for federally endangered smooth coneflower (Echinacea
laevigata). The Dan River exhibits potential habitat for the federally endangered Roanoke logperch
(Percina rex) and the James spiny mussel (Pleurobema collina).

4. Is the site potentially used as a breeding, roosting or feeding area by migratory bird species? If yes,
identify which species.
Migratory birds listed on the USFWS’s Information for Planning and
Conservation (IPac) website that may use habitats onsite include American bittern (Botaurus
lentiginosus), bald eagle (Haliaeetus leucocephalus), blue-winged warbler (Vermivora pinus), brown-
headed nuthatch (Sitta pusilla), Chuck-will’s-widow (Caprimulgus carolinensis), fox sparrow
(Passerella iliaca), Kentucky Warbler (Oporornis formosus), least bittern (Ixobrychus exilis),
loggerhead shrike (Lanius ludovicianus), prairie warbler (Dendroica discolor), Prothonotary
warbler (Protonotaria citrea), red-headed woodpecker (Melanerpes erythrocephalus), rusty blackbird
(Euphagus carolinus), wood thrush (Hylocichla mustelina), and worm eating warbler (Helmitheros
vermivorum).

2 Areas that provide unique and often protected habitat for wildlife species. These areas are typically used during critical life
stages such as breeding, hatching, rearing of young and overwintering. Refer to Table 2 at the end of this document for
examples of sensitive environments.
A-37

Sensitive Environments and Receptors Questions (Continued)

5. Is the site used by any ecologically3, recreationally or commercially important species? If yes, explain.
Correspondence with NCWRC indicated that the Dan River is used for recreational fishing.
Recreational aquatic species include: largemouth bass (Micropterus salmoides), catfish, and sunfish. It
is likely the site is too industrialized to support any ecologically, recreationally or commercially
important terrestrial wildlife species. However, raccoon, opossum, skunk , white-tailed deer, coyotes,
and other species commonly found throughout the Northern Piedmont region may be found on the site.
Recreationally important wildlife species in the vicinity of the site include, but are not limited to: bear,
white-tailed deer, beaver, mink, muskrat, nutria, otter, skunk, weasel, bobcat, opossum, raccoon, fox,
rabbit, squirrel, various species of wild ducks and geese, quail, and wild turkey.

3 Ecologically important species include populations of species which provide a critical (i.e., not replaceable) food resource for
higher organisms. These species' functions would not be replaced by more tolerant species or perform a critical ecological
function (such as organic matter decomposition) and will not be replaced by other species. Ecologically important species include
pest and opportunistic species that populate an area if they serve as a food source for other species, but do not include
domesticated animals (e.g., pets and livestock) or plants/animals whose existence is maintained by continuous human
interventions (e.g., fish hatcheries, agricultural crops, etc.).
