NARRATIVE SUMMARY
The Georgia-Pacific Corporation Hardwood Sawmill, EPA ID No. NCD000813592,
comprises approximately 24.11 acres. The facility is located on Plywood Drive
along the Roanoke River in Plymouth, Washington County, North Carolina.
Atlas Plywood Company owned this tract of property prior to 1950, and operations
at the property prior to then are unknown. Around 1950, Georgia-Pacific
Corporation purchased the property. All of the existing structures were torn
down, and a new facility was built. Operations at the new facility included the
production of hardwood lwnber and railroad ties. Wood treating operations at the
facility included the use of pentachlorophenol and lindane.
Georgia-Pacific Corporation Hardwood Sawmill filed a Resource Conservation and
Recovery Act (RCRA) Part A application on November 12, 1980. The facility was
listed under RCRA as a large quantity generator and storer of hazardous waste.
However, in August 1982, the facility was deleted as a large quantity generator
and.storer, and added as a small quantity generator.
The main area of concern at the Georgia-Pacific Corporation Hardwood Sawmill is
the area of contaminated soil around the conveyor belt and dip vat area. A 1981
RCRA inspection noted that wood treatment chemicals were dripping off the treated
wood, directly onto the ground. These included a wood fungicide and insecticide.
The wood fungicide is known to have contained pentachlorophenol, and the
insecticide is known to have contained lindane. Reportedly, the waste product
that had spilled onto the ground was removed and burned in the on-site boilers.
During renovation operations in 1983, the entire facility burned and was
permanently closed. In 1985, the property was sold to Decatur Partnerships based
out of Kitty Hawk, North Carolina. Decatur Partnerships is the current owner of
the property. For a brief period of time, Decatur Partnerships leased a portion
of the south end of the property to Outerbanks Contractors, which used this
portion of land as an asphalt mixing plant. The entire property is presently
unoccupied. Although access to the property is restricted by a gS.ted entrance,
there is evidence of trespassing.
In June 1995 the· North Carolina Department of Environment, Heal th and Natural
Resources, Division of Waste Management conducted an expanded site inspection
(ESI) at the facility. Soil samples collected from the dip vat area during the
ESI contained elevated concentrations of contaminants attributable to site
processes.
The entire surface water Pathway along the Roanoke River to Albermarle Sound is
fished both commercially and recreationally. Level II concentrations of arsenic
and 2,3,7,8-tetrachlorodibenzofuran have been identified in this fishery.
Additionally, the wetlands contiguous to this segment of the river were evaluated
as Level II.

Pathways, Components, or Threats Not Evaluated
The groundwater migration and air migration pathways were not scored in this
evaluation because these pathways are not expected to significantly
contribute to the overall site score. Although groundwater samples were
collected, an observed release to groundwater was not scored. No air
samples have been collected to document a release to ambient air.
Although surface soil contamination has been identified throughout the
facility property and adjacent properties, a significant nwnber of soil
exposure targets have not been identified for this pathway.

Source No. : .1
SOURCE DESCRrPTrON
Name and description of the source: Contaminated Soil
Atlas Plywood Company conducted operations at the facility property prior to
1950. It was purchased by Georgia-Pacific Corporation ·around 1950 (Ref. 5, p.
l; 6, p. 1). There is no known documentation of the operating practices
employed by Atlas Plywood Company (Refs. 7, p. 5; 8, p. 2-1). When the
Georgia-Pacific Corporation bought the property around 1950, all of the
existing buildings were demolished and a new facility was constructed (Refs.
5, p. l; 6, p. 1). A fire occurred at the Georgia-Pacific Corporation
Hardwood Sawmill in 1983, after which the facility was permanently closed
(Refs. 5, p. 1; 6, p. 1; 9).
From 1950 to 1980, operations at the facility included debarking, sawing, and
planing rough lumber from logs. Raw rough wood was treated via passing
through a dip vat located at the end of a conveyer system (Refs.7, p. 5; 8, p.
2-1; 10, p.2; 21, p.l). The raw wood was treated with solutions containing
pentachlorophenol and other chlorophenols, and lindane (Ref. 21, p.l).
Source No. 1 is an area of contaminated soil in the vicinity of the former
conveyer system and dip vat (Refs. 11; 12; 21, ·p. 1). Soil in this area was
contaminated from excess wood preservative dripping off the treated lumber
(Ref. 21, p. 1).
_Location of the source, ~ith reference to~ map of the site: Source No. 1,
the area of contaminated soils around the former dip vat and conveyor area, is
located in the central portion of the facility property, northeast of the
former boiler. Elevated levels of constituents have been detected at four
sampling locations in Source No. 1 (also see pages 15 -18 in this
documentation record). The concentration of an analyte is considered elevated
if the concentration is equal to or greater than three times the concentration
in the background/control sample, or greater than or equal to the minimum
quantitation limit (MQL) if the constituent is not detected in the
background/control sample (Refs. 1, Table 2-3; 8, Figure 2-2; also see Figure
3 on page 8 in this documentation record).
Containment: Release via overland migration and/or flood: No known surface
water runoff control systems or runof_f management systems have been associated
with the area of on-site contaminated soils. In addition, there is evidence
that hazardous substances associated with this source are present in the
Roanoke River (Ref. 7, Appendix A; also see pages 23 -58 in this
documentation record).

• • SWOF-Surface Water Overland Flow/Flood Migration· Pathway
4.1 OVERLAND/FLOOD MIGRATION COMPONENT
4.1.1.1 DEFINITION OF HAZARDOUS SUBSTANCE MIGRATION PATH FOR
OVERLAND/FLOOD COMPONENT
Surface water runoff from Georgia-Pacific Corporation Hardwood ·sawmill
enters the Roanoke River via a drainage ditch that runs along the entire
perimeter of the facility property (Refs. 7, p. 15; 15). Overland
drainage that flows to the ditch enters the Roanoke River on the western
edge, or farthest upstream probable point of entry (PPE #1) (Refs. 7, p.
15; 8, p. 2-4; 15). Overland drainage also enters the Roanoke River from
the eastern property boundary via the perimeter drainage ditch (PPE #2)
(Refs. 7, p. 15; 15). The distance between PPE #1 and PPE #2 is
approximately 1,100 to 1,200 feet (Refs. 3; 8, Figures 1-1, 2-1). The
intermittent drainage ditch is approximately 300 feet east of Source No. 1
(Ref. 8, Figure 2-2). Overland flow from Source No. 1 is directed toward
the intermittent ditch and the Roanoke River (Refs. 3; 43). From entry
into the intermittent drainage ditch, drainage flows north along the ditch
approximately 200 feet north prior to entering the Roanoke River at PPE #2
(Ref. 43). Surface soil sample GP-002-SL, collected from the intermittent
drainage ditch east of the dip vat area (Source No. 1) during the ESI,
contained the following hazardous substances: arsenic (5.4 mg/kg), copper
(13J mg/kg), lead (250 mg/kg), zinc (lOOJ mg/kg), 2,3,7,8-
tetrachlorodibenzodioxin (19J ng/kg), 1,2,3,7,8-pentachlorodibenzodioxin
(170 ng/kg), pentachlorodibenzodioxin (total) (650J ng/kg), 1,2,3,4,7,8-
hexachlorodibenzodioxin (220 ng/kg), 1,2,3,6,7,8-hexachlorodibenzodioxin
(830 ng/kg), 1,2,3,7,8,9-hexachlorodibenzodioxin (500 ng/kg),
hexachlorodibenzodioxin (total) (4,600J ng/kg), 1,2,3,4,6,7,8-

Appendix A, pp. 8, 83; Also see Figure 3 on page 8 of this documentation
record).
PPE #2 is the farthest downstream PPE for Georgia-Pacific Corporation
Hardwood Sawmill; therefore, the 15-mile surface water migration pathway
target distance limit (TDL) was calculated from this point. From PPE #2,
surface water flows northeast along the Roanoke River for approximately
2.75 miles, where the Eastmost River begins. Flow continues in the
Eastrnost River for approximately 2.6 miles before converging with
Albermarle Sound, and 2.5.miles in the Roanoke River before converging
with Albermarle Sound. The 15-rnile surface water migration pathway TDL is
completed in Albermarle Sound (Ref. 3; Also see Figure 4 on page 9 of this
documentation record).

revealed the presenc_e of site-related hazardous constituents. Soil
samples collected from the dip vat area during the Phase II, Screening
.Site Inspection (SSI) contained detectable. concentrations of cobalt,
copper, lead, alpha-BHC, delta-BHC, and gamma-BHC (lindane). Dioxin and
furan analyses were not performed on these samples (Ref. 19, pp. 12, Table

Prior to 1950, Atlas Plywood Company owned the facility property; little
is known about the operations during this time period (Ref. 5, p. 1).
Around 1950, the property was purchased by Georgia-Pacific Corporatio~ and
all existing buildings were demolished and a new production facility built
(Ref. 5).
Operations conducted during the Georgia-Pacific ownership included the
production of hardwood lurnber,and railroad ties (Ref. 21). The existing
facility burned in 1983, and the facility was permanently closed (Refs. 5,
p. l; 6, p. 1). In 1985, the property was sold to Decatur Partnerships
(Ref. 91. Outerbanks Contractors leased a portion of the property for the
purpose of mixing asphalt (Ref. 20). This activity had ceased by June
1995 (Ref. 20) .
Wood treatment operations at the facility consisted of passing wood along
a conveyor belt and through a dip vat (Ref. 21, p. 1). The dip vat
contained a mixture of wood treatment chemicals and pesticides (Ref. 21,
p. 1). The chemicals used for this treatment were produced by the Koppers
Company of St. Louis, Missouri (Ref. 21, p .. 1). The wood fungicide used
is known by the trade name "Noxtane" and contains pentachlorophenate, and
sodium metaborate (Ref. 21, p. 1). In addition to Noxtane,· lindane was
also included in the treatment mixture (Ref. 21, p. 1). After wood passed
through the dip vat, excess preservative on the finished wood spilled (the
pentachlorophenate-lindane mixture) to the ground in the vicinity of the
conveyor (Ref. 21, p. 1). This contaminated soil was allegedly
periodically burned in the on-site boilers (Ref. 21, p. 1).
Pentachlorophenol, a common wood preservative, often contains high
concentrations of dioxins and furans (Ref. 22, p. 1}. Wood treatment
facilities where a past common practice has been burning waste
pentachlorophenol have produced large amounts of dioxins and furans (Ref.
22, p. 2). Treated wood and scrap wood that has been periodically burned
at facilities has been a source of dioxins and furans (Ref. 22, p. 2).
30
• SWOF-Observed Release
Dioxins are formed as by-products of incomplete burning of chlorinated
compounds during incineration at low levels (Ref. 23, p. 1). Incineration
of chlorinated compo4nas is a major source of dioxin congeners (Ref. 23,
p. 2). High-temperature incineration is the most effective method of
removing dioxins via burning (Ref. 22, p. 2; 23, p. 2).
Dioxins can be produced when a source of chlorine is present along with
chlorine-reactive chemicals (Ref. 23, p. 2). Several dioxin congeners can
be by-products during the formulation of chlorinated pesticides, including
pentachlorophenol (Ref. 23, p. 2).
Polychlorinated biphenyls (PCBs) that are common in transformers produce
large amounts of dioxins and·furans when burned (Ref. 22, p. 2). Dioxins
and furans are also produced during the bleaching process of pulp and
paper production (Ref. 23, p. 2). Paper bleaching is employed by the
Weyerhaeuser Corporation, upstream of Georgia-Pacific (Ref. 39, p. 4). No
creosote or pentachlorophenol has been used at the Weyerhaeuser
Corporation (Ref. 39, p. 4). There are no other known potential sources
of dioxins and furans known to be on this segment of the Roanoke River
(Ref. 41). Buildings·depicted on the topographic map between the
Weyerhaeuser Corporation, and Georgia-Pacific are downtown Plymouth, North
Carolina and consist of a barber.shop, police station,· and various· other
small businesses (Ref. 41).

Closed Fisheries
No known closed fisheries are located within the 15-mile surface water
migration pathway target distance limit; however, a fish consumption
advisory is in effect for the entire 15-mile surface water pathway (Ref.
27, p. 16). This advisory includes all fish except herring and shad
(Ref. 27, p. 16). No consumption of fish is recommended for pregnant or
nursing women, and children. For the general population, no more than
two meals containing fish are recommended per month (Refs. 27, p. 16;
28) .

The average mean flow rate for the Roanoke River for 1997 was
approximately 10,750 cubic feet per second {cfs) (Ref. 29, pp. 64, 65).
This flow, however, was measured approximately 128 miles upstream of the
facility {Ref. 29, pp. 64, 65). The average outflow of the Roanoke River
into Albermarle Sound is approximately 8,900 cfs {Ref. 30, p. ,100).
Therefore, for purposes of this documentation record, ·the flow for the
Roanoke River at the facility was conservatively estimated to be greater
than 10,000 cfs. The entire 15-mile target distance limit for Georgia-
Pacific Corporation Hardwood Sawmill is fished {Ref. 24). This includes
the Roanoke River from Plymouth, North Carolina, to Albermarle Sound
{Refs. 3; 24; 25, pp. 2, 12). The annual production of fish in pounds
from the 15-mile surface water migration pathway was not available.
Therefore, for scoring purposes, the annual production was assumed to be
greater than zero.

Sediment sample GP-010-SD, collected approximately 1,300 feet downstream of PPE #1, is the most distant sample collected adjacent to the wetland area contiguous with the Roanoke River and downstream of the Georgia-Pacific Hardwood sawmill (Refs. 7, Figure 2; 311. Approximately 1,800 feet of wetlands frontage were determined to be affected by Level II concentrations (Refs. 1, Table 4-24; 3; 7, Figure 2; 31). Based on the Wetlands Inventory Maps of Plymouth East and Westover, North Carolina, the wetland areas contiguous with the Roanoke River where sediment sample GP-010-SD was collected are classified as palustrine forested broad-leaved deciduous (PFOlA) and palustrine forested deciduous semipermanently flooded (PFO6F) (Ref. 31). Also see Figure 4 on page 9 of this documentation record.
