Dissolved chromium, lead, and thallium concentrations in all ash pore water and seep samples, including the S-10 seep sample, were below their respective method detection limits and 2L standards. Note 4 - Naturally occurring at moderate concentrations In most water bearing units, present at moderate concentrations In many foods and available in dietary supplements. Unlikely to pose potentially unacceptable risk to human health when compared to other coal ash constituents. PADuke Energy Progress, 1026\109.

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 [axon under consideration for official listing for which there is sufficient information to support listing. (Formerly "Cl" candidate species.) BGPA =Bald and Golden Eagle Protection Act. See below. FSC=Federal Species of Concern. FSC is an informal tens. 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. 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. P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT", respectively. Said and Golden Eagle ProtetHon Att lBGPAI: In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de-Iisted) from the Federal List of Threatened and Endangered wildlife. This desisting 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 Threatened due to sim laritv of aooeauance(T(S/A1h 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 Dooulatlon of the boa turtle as a Federal species of 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. Definition of State Codes: CODE/STATUS DEFINITION Any native or once -native species of wild animal whose continued existence as a viable component of the State's fauna is determined E=Endangered 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 T=Threatened 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). SC=Special Any species of wild animal native or once -native to North Carolina which is determined by the Wildlife Resources Commission to Concern 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. SR=Significantly Natural Heritage Program to need monitoring. Significantly Rare species Include "peripheral" species, whereby North Carolina Iles at Rare 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.

SC-V=Special Concern- "Any species or higher taxon of plant which is likely to become a threatened species within the foreseeable future"(NCAC 02 NCAC 48F .0401). Vulnerable SC-H=Special Concern- "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). Historical SR-L= The range of the species is limited to North Carolina and adjacent states (endemic or near endemic). These are species that may Significantly Rare have 20-50 populations In North Carolina, but fewer than 100 populations rangewide. The preponderance of their distribution is in Limited North Carolina and their fate depends largely on conservation here. SR- T=Significantly Rare Throughout The species is rare throughout Its range (fewer than 100 populations total). SR- D=Significantly Rare Disiunct The species is disjunct to North Carolina from a main range In a different part of the country or world. SR- The species is at the periphery of its range in North Carolina. These species are generally more common somewhere else In their P=Slgnificantly ranges, occurring In North Carolina peripherally to their main ranges, mostly In habitats which are unusual in North Carolina.
