Attn: Russell Grant 121 Washington Avenue Weldon, NC 27890 To Whom It May Concern: rq?ECE1'1VED ;4ID WASTE a Notice of Violation- Intent to Enforce NOV-PC-2016-0226 DWM ID CCB0064 Henry Long Property NC Hwy 48, PIN 4918-28-8013 Northampton County 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 Division of Water Resources, Raleigh Regional Office, Water Quality Operations Section http:G'portal.ncdenr,org, Webhaq/aps 1628 Mail Service Center, Raleigh, NC 27699-1628 Phone: (919) 791-4200 Location: 3800 Barrett Drive, Raleigh, NC 27609 Fax: (919) 788-7159 October 21, 2016 Page 2 of 15 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. October 21, 2016 Page 3 of 15 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 Page 5 of 15 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.
