On March 3, 2016, Laura Robertson, Danny Smith, and Autumn Romanski with the Raleigh
Regional Office (RRO) of the Division of Water Resources (DWR) conducted an investigation
of the subject site. Also present were Shawn McKee and Mary Whaley from the Division of
Waste Management (DWM). The site visit revealed that wastewater was leaching/seeping from

the waste ash pile. This waste was coursing into an adjacent wetland and an intermittent stream
(an unnamed tributary) that flows to Arthurs Creek (Class C, Stream Index 23-28).
Specifically, the site visit, field observations, sampling results, and the subsequent file review
revealed the following:
• On April 23, 2004, a notification was made by Plumbline Corporation P.A. to the
NCDENR (now NCDEQ) Division of Waste Management for a structural fill beneficial
use project. The Coal Combustion Byproduct Reuse Plan was called Arthur's Creek
Development Project in Northampton County, NC. A DWM project number, CCB0064,
was issued to use coal combustion by-products/residuals as structural fill at the site, per
15A NCAC 13B .1700 Solid Waste Section Rules.
• Approximately 480,612 cubic yards of coal combustion residuals/products were utilized
in the construction of the structural fill beneficial use project. The structural fill operation
was performed by Plumbline Corporation, P.A. Engineering and Land Surveying of
Weldon, NC. The coal: combustion products were generated by the Roanoke Valley
Energy Facility owned by Westmoreland LG&E Partners in Weldon, NC.
• The stated purpose of the structural fill in the Notification received by the DWM Solid
Waste Section on April 23, 2004 was "to provide a site ready for development, for which
office buildings, and associated parking lot and access road can be constructed."
• In 2006, mitigation credits were sought by the property owner for the construction of an
air strip at the property, called the Long Airstrip Project. In February 2007, Plumbline
Engineering suggested to bridge over the stream after a site visit from DWQ (now
DWR).
• As of March 2016, no buildings have been constructed on the property. It does not appear
that the bridging nor the construction of an air strip was.begun on the site. The status of
the site remains fallow with dog fennel and broom straw successional growing.
• The facility's structural fill area was required to be covered with a minimum of 12-inches
compacted earth and an additional 6-inches of surface soil capable of supporting native
vegetation as per 15A NCAC 13B .17050). Photos from this investigation and previous
investigations do not support that more than 6-inches of soil was used as cover.
• The site visit revealed coal combustion residuals leaching/seeping from the waste ash
pile. This waste was coursing into an adjacent wetland and into an intermittent stream
(an unnamed tributary) that flows to Arthurs Creek.
• A relict sediment basin (designated as East Sediment Basin or ESB) that outlets to
Arthurs Creek was also observed. This basin also contains coal combustion residuals
waste.
• The toe of the ash basin (southern end) exhibited areas of stressed, dead, and dying
vegetation. Also, there were areas exposed to the structural fill leachate that were
completely devoid of vegetation. In these areas, nothing was growing and the exposed
bare soils were eroding into the downslope wetland.
• In March 2016, surface water samples were collected from the (1) Upstream location of
Arthurs Creek (north of Hwy 48), from the (2) Wetland area, the (3) Unnamed Tributary
to Arthurs Creek, and from (4) a relict sediment basin (East Sediment Basin) that outlets
to Arthurs Creek. These results are presented in the tables in Attachment A.

The streams on site include Arthurs Creek and an unnamed tributary to Arthurs Creek
that are classified as Class C Waters in the Roanoke River basin.
These observations and findings constitute violations of the following North Carolina General
Statutes and North Carolina Administrative Codes:
NCGS 143-215.1(a) (1)
"Activities for Which Permits Required. — No person shall do any of the following things or carry
out any of the following activities unless that person has received a permit from the Commission
and has complied with all conditions set forth in that permit.
(1) Make any outlet into the Waters of the State."
Item I. Stream Standards - Removal of Use
Title 15A North Carolina Administrative Code 02B .0211 (2) requires that "The waters shall be
suitable for aquatic life propagation and maintenance of biological integrity, wildlife, secondary
recreation, and agriculture; sources of water pollution which preclude any of these uses on either
a short-term or long-term basis shall be considered to be violating a water quality standard." (See
data in Attachment A.)
DWR staff collected one upstream and three samples downgradient of the coal
combustion residuals structural fill area. The three downgradient samples showed
markedly large increases in concentrations, compared to the upstream sample, for the
following:
Aluminum, arsenic, barium, boron, calcium, iron, lithium, manganese, nickel, selenium,
strontium, titanium, zinc, hardness, chloride, sulfate, bromide, total dissolved solids, and
specific conductivity.
• The wetland and unnamed tributary samples results for pH were 3.03 and 3.39 SU,
respectively.
Item II. Stream Standards - Metals
Title 15A North Carolina Administrative Code 02B .0211 (11) (b) lists freshwater metals
standards that are not hardness -dependent (including arsenic and selenium). These results are
detailed in tables in Attachment A.
Title 15A North Carolina Administrative Code 02B .0211 (11) (c) lists freshwater metals that are
hardness -dependent (including nickel and zinc). These results are detailed in tables in
Attachment A Cont'd.
October 21, 2016
Page 4 of 15
Item III Stream Standards - Oils; deleterious substances; colored or other wastes
Title 15A North Carolina Administrative Code 02B .0211 (12) requires that "Oils; deleterious
substances; colored or other wastes: only such amounts as shall not render the waters injurious to
public health, secondary recreation or to aquatic life and wildlife or adversely affect the
palatability of fish, aesthetic quality or impair the waters for any designated uses;"
(See photos in Attachment B.)
• Pursuant to 15A NCAC 02B .0211 (11) (c) (i), The standards for nickel and zinc
were calculated with a hardness of 400 mg/L CaCO3.
• Comparing the upstream sampling location on Arthurs Creek to the sediment
basin, wetland, and tributary samples downstream, there are increases in metals
concentrations on orders of magnitude.
• Due to the lack of sufficient cover soils and/or lining of the coal combustion
residuals fill area, fill and leachate from the fill area continuously flow into the
wetland area, the unnamed tributary, and the east sediment basin. The entire
length of wetland and tributary stream on the property have been impacted.
• Specifically, leachate was seen along the base of the structural fill area, and all
vegetation near the structural fill area in the wetland was dead.
• The chloride concentrations in the east sediment basin, wetland area, and
unnamed tributary to Arthurs Creek chloride were 2,900, 9,500, and 2,200 mg/L,
respectively.
• Total aluminum concentrations were above the EPA National Aquatic Life
Criteria for freshwater — which is an acute concentration of 750 µg/L; a limit that
is set for a pH range of 6.5-9.0. Low pH and the synergistic effects of acidic
conditions can cause increased aluminum toxicity.
Item IV. Stream Standards -PH
Title 15A North Carolina Administrative Code 02B .0211(14) requires that, "pH: shall be normal
for the waters in the area, which range between 6.0 and 9.0 except that swamp waters may have a
pH as low as 4.3 if it is the result of natural conditions;"
• The pH of the wetland area and unnamed tributary were 3.03 and 3.39 SUs, respectively,
during the March 2016 sampling event.
October 21, 2016

Item V. Wetland Standards
Title 15A North Carolina Administrative Code 02B .0231(b) requires that:
(1) Liquids, fill, or other solids or dissolved gases may not be present in amounts which may
cause adverse impacts on existing wetland uses;
(2) Floating or submerged debris, oil, deleterious substances, or other material may not be
present in amounts which may cause adverse impacts on existing wetland uses;
(4) Concentrations or combinations of substances which are toxic or harmful to human,
animal, or plant life may not be present in amounts which individually or cumulatively
may cause adverse impacts or existing wetland uses;
(5) Hydrological conditions necessary to support the biological and physical characteristics
naturally present in wetlands shall be protected to prevent adverse impacts on:
(C) The chemical, nutrient, and dissolved oxygen regime of the wetland;
(D) The movement of aquatic fauna;
(E) The pH of the wetland; and
(F) Water levels or elevations;
• The pH of the wetland area and unnamed tributary were 3.03 and 3.39 SUs,
respectively, during the March 2016 sampling event.
• Total aluminum concentrations were well above the EPA Freshwater Aquatic Life
recommended criteria at an acute level of 750 µg/L; 7,000 µg/L in the wetland
and 7,400 µg/L in the unnamed tributary.
• The chloride concentrations in the east sediment basin, wetland area, and
unnamed tributary to Arthurs Creek were 2,900; 9,500; and 2,200 mg/L,
respectively.
• Metals results showed dissolved selenium concentrations above the 15A NCAC
02B Standard.
• Wetland samples results are in Attachment A tables.
Item VI. Groundwater Assessment
Title 15A North Carolina Administrative Code 02L .0106(b) requires that "Any person
conducting or controlling an activity that results in the discharge of a waste or hazardous
substance or oil to the groundwaters of the State, or in proximity thereto, shall take action upon
discovery to terminate and control the discharge, mitigate any hazards resulting from exposure to
the pollutants and notify the Department, as defined in 15A NCAC 02C .0102, of the discharge."
Leachate containing waste coal combustion residuals was observed on the ground surface
hydraulically down -gradient from the coal ash fill. The Department received no notification of
the discharge of waste coal combustion residuals leachate at this facility.
