A-8

HA. SUMMARYOFOBSERVATIONSANDSITESETTING
Include information on significant source areas and migration pathways that are
likely to constitute complete exposure pathways.
The coal ash stored on site, in both ash basins on site, is likelv to be the
source of anv potential COCs found in groundwater, soils, sediments and
surface water. Surface water or rain water run off can carry coal ash from
areas where it is exposed (such as in the basin to the east of the facility)
and transport the material down gradient (towards the Cape Fear River or
the Haw River) from the basins. COCs could percolate into soil and
groundwater after transported out of the basin. If carried by surface
water, such as the rivers on site and downstream, the COCs can settle into
the sediment.

Sensitive Environments and Receptors Questions (continued)
Is the site used by any ecologically", recreationally or commercially important
species? If yes, explain.
The Cape Fear Shiner is an ecologically important species, accordinq to
the U.S. Fish and Wildlife Service, due to its position as an indicator species
The species also Nays a vital role in maintaininq the biodiversitv of its
habitat.
° 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).
