Notes:
1. Estimated boring and well depths based on data available at the time of work plan preparation and subject to change based on site-specific conditions in the field.
2. Laboratory analyses of soil, ash, groundwater, and surface water samples will be performed in accordance with the constituents and methods identified in Tables 10 and 11.
3. Additionally, soils will be tested in the laboratory to determine grain size (with hydrometer), specific gravity, and permeability.
4. During drilling operations, downhole testing will be conducted to determine in-situ soil properties such as horizontal and vertical hydraulic conductivity.
5. * = Compliance monitoring well will be sampled during routing compliance montoring event in March 2015.

Definitions of Federal Status Codes:
E = endangered. A taxon "in danger of extinction throughout all or a significant portion of its range."
T = threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a significant portion of its range."
C = candidate. A taxon under consideration for official listing for which there is sufficient information to support listing. (Formerly "C1" candidate species.)
BGPA =Bald and Golden Eagle Protection Act. See below.
P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT", respectively.
Bald and Golden Eagle Protection Act (BGPA):
Threatened due to similarity of appearance(T(S/A)):
Definitions of Record Status:
Current - the species has been observed in the county within the last 50 years.
Historic - the species was last observed in the county more than 50 years ago.
Obscure - the date and/or location of observation is uncertain.
Incidental/migrant - the species was observed outside of its normal range or habitat.
Probable/potential - the species is considered likely to occur in this county based on the proximity of known records (in adjacent counties), the presence of potentially suitable habitat, or both.

T(S/A) = threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with another listed species
and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered or threatened and are not subject to Section 7
consultation. See below.
EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental, nonessential populations of
endangered species (e.g., red wolf) are treated as threatened species on public land, for consultation purposes, and as species proposed for
listing on private land.

FSC=Federal Species of Concern. FSC is an informal term. It is not defined in the federal Endangered Species Act. In North Carolina, the
Asheville and Raleigh Field Offices of the US Fish and Wildlife Service (Service) define Federal Species of Concern as those species that
appear to be in decline or otherwise in need of conservation and are under consideration for listing or for which there is insufficient
information to support listing at this time.Subsumed under the term "FSC" are all species petitioned by outside parties and other selected
focal species identified in Service strategic plans, State Wildlife Action Plans, or Natural Heritage Program Lists.
In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de-listed) from the Federal
List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After delisting, the Bald and Golden Eagle Protection Act
(Eagle Act) (16 U.S.C. 668-668d) becomes the primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles
and provides a statutory definition of "take" that includes "disturb". The USFWS has developed National Bald Eagle Management Guidelines
to provide guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information, visit
http://www.fws.gov/migratorybirds/baldeagle.htm
In the November 4, 1997 Federal Register (55822-55825), the northern population of the bog turtle (from New York south to Maryland) was
listed as T (threatened), and the southern population (from Virginia south to Georgia) was listed as T(S/A) (threatened due to similarity of
appearance). The T(S/A) designation bans the collection and interstate and international commercial trade of bog turtles from the southern
population. The T(S/A) designation has no effect on land management activities by private landowners in North Carolina, part of the southern
population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern population of
the bog turtle as a Federal species of concern due to habitat loss.
Any native or once-native species of wild animal whose continued existence as a viable component of the State's fauna is
determined by the Wildlife Resources Commission to be in jeopardy or any species of wild animal determined to be an
'endangered species' pursuant to the Endangered Species Act. (Article 25 of Chapter 113 of the General Statutes; 1987).
Any native or once-native species of wild animal which is likely to become an endangered species within the foreseeable
future throughout all or a significant portion of its range, or one that is designated as a threatened species pursuant to the
Endangered Species Act. (Article 25 of Chapter 113 of the General Statutes; 1987).
Any species of wild animal native or once-native to North Carolina which is determined by the Wildlife Resources
Commission to require monitoring but which may be taken under regulations adopted under the provisions of this Article.
(Article 25 of Chapter 113 of the General Statutes; 1987).
Any species which has not been listed by the N.C. Wildlife Resources Commission as an Endangered, Threatened, or
Special Concern species, but which exists in the state (or recently occurred in the state) in small numbers and has been
determined by the N.C. Natural Heritage Program to need monitoring. Significantly Rare species include "peripheral"
species, whereby North Carolina lies at the periphery of the species' range (such as Hermit Thrush), as well as species of
historical occurrence with some likelihood of re-discovery in the state. Species considered extirpated in the state, with little
likelihood of re-discovery, are given no N.C. Status (unless already listed by the N.C. Wildlife Resources Commission as E,
T, or SC).
Species is a game animal or a furbearer, and therefore (by law) cannot be listed for State protection as E, T, or SC.
“Any species or higher taxon of plant which is likely to become a threatened species within the foreseeable future"(NCAC
02 NCAC 48F .0401).

“Any species or higher taxon of plant that occurred in North Carolina at one time, but for which all known populations are
currently considered to be either historical or extirpated.” "(NCAC 02 NCAC 48F .0401).
The range of the species is limited to North Carolina and adjacent states (endemic or near endemic). These are species
that may have 20-50 populations in North Carolina, but fewer than 100 populations rangewide. The preponderance of their
distribution is in North Carolina and their fate depends largely on conservation here.
The species is rare throughout its range (fewer than 100 populations total).
The species is disjunct to North Carolina from a main range in a different part of the country or world.
The species is at the periphery of its range in North Carolina. These species are generally more common somewhere else in
their ranges, occurring in North Carolina peripherally to their main ranges, mostly in habitats which are unusual in North
Carolina.The range of the species is sporadic or cannot be described by the other Significantly Rare categories
Any other species believed to be rare and of conservation concern in the state but not warranting active monitoring at this
