(HGL) to describe the sampling objectives, project schedule, and quality assurance (QA) and quality control (QC) requirements for Remedial Action (RA) Oversight sampling and analysis activities at the Holcomb Creosote Company (HCC) Site located in Yadkinville, Yadkin County, North Carolina. The purpose of the field investigation activities is to collect data to support the Site’s separate soil and groundwater RAs. This work will be completed in accordance with the requirements of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This project is being conducted for the U.S. Environmental Protection Agency (EPA) Region 4 under Design and Engineering Services (DES) Contract 68HE0318D0006, Task Order (TO) 68HE0422F0071. This plan is specific to the HCC Site and meets the requirements and elements set forth in the EPA guidance document entitled Uniform Federal Policy for Quality Assurance Project Plans prepared by the Intergovernmental Data Quality Task Force (IDQTF) in 2005 with the optimized worksheets developed by IDQTF in 2012. It also includes supplemental information and requirements, as necessary, to support Site-specific objectives. The UFP-QAPP is the primary planning document for TO activities. It includes the project organization, planned activities, and QA/QC procedures necessary to complete this work. The UFP-QAPP will be implemented to ensure that the data collected are valid for the intended end use and that data meet the requirements of the data quality objectives (DQOs). Several other planning documents prepared by HGL complement the UFP-QAPP and should be used in conjunction with this document:  A Field Sampling Plan (FSP) (Appendix A of this UFP-QAPP) that describes the sampling objectives and activities for completing the RA data collection. The FSP includes guidance for all field work by defining, in detail, the sampling and data-gathering methods to be used during sampling activities.  A Data Management Plan (DMP) (Appendix B of this UFP-QAPP) that provides procedures for managing field and laboratory data generated by the field investigations.  A Waste Management Plan, included as part of the FSP that describes procedures for safe storage and disposal of wastes that will be generated during fieldwork.  A Site Management Plan that addresses the coordination and control of Site activities during the field investigation. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 2 • A Site-specific Health and Safety Plan (HASP), submitted as a separate deliverable, that defines the preventative and protective procedures that will be implemented during the field activities to ensure the safety of the field team. Newly acquired data obtained from the field activities proposed in this UFP-QAPP will be used along with existing data from previous Site investigation and remediation activities to support the soil and groundwater RAs.

HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 11 WORKSHEET #10 CONCEPTUAL SITE MODEL Environmental Problem Soil, groundwater, and sediment at the HCC Site have been impacted by creosote-related contaminants from former wood treating operations on the property, as documented in the Final Remedial Investigation Report (Versar, 2017), the Final Groundwater Data Evaluation and Conceptual Site Model Update Technical Memorandum (HGL, 2020a), the Final Soil Data Evaluation and Conceptual Site Model Update Technical Memorandum (HGL, 2020b), and the Final (100%) Soil Remedial Design (HGL, 2021). Additional soil, groundwater, and sediment data are needed to fully define the extent of contamination above cleanup goals and support the separate soil and groundwater RAs in accordance with the Site’s Record of Decision (ROD). Site Location and History The HCC Site is located at 5016 U.S. Highway 601, just north of Yadkinville in Yadkin County, North Carolina (Figure 1). The geographic coordinates of the Site, as measured near the former concrete storage pit, are latitude 36.1579 degrees (°) North and longitude 80.6752° West. The office building and storage building, located on the western portion of the property along U.S. Highway 601 are the only structures remaining at the Site. Structures formerly located on HCC include the creosote storage tanks, pressure treatment vessel, drip pad and sump, canopy covering the drip pad, concrete storage pit, steel settling tank, distillation evaporator, and untreated and treated wood storage areas. The location of these Site features within the former operations area is shown in Figure 2. HCC conducted wood treating operations on the property from 1951 to 2009. In 2011, HCC was referred to EPA’s Superfund program to address known and potentially hazardous waste contamination under CERCLA. The Site was placed on the National Priorities List in 2012. From 1951 to 2009, HCC operated a wood treating facility on the Site property. HCC manufactured pressure-treated posts and lumber using creosote coal tar solutions. During facility operations, wood products were placed in a pressurized treatment vessel and heated with steam to open the pores of the wood and remove sap and resin. After an allotted time, the vessel was vented to decrease the interior pressure, and a vacuum was drawn to remove moisture. Following application of the vacuum, creosote was forced into the pores of the wood. The vapor stream from the treatment vessel was passed through a condenser, where the water and creosote mixture was liquefied. After treatment, condensate from the condenser and from depressurization of the treatment vessel was pumped to a concrete-lined settling tank (i.e., the concrete storage pit). This liquid was pumped from the concrete storage pit to a steel settling tank, where the solids settled to the bottom. The liquids were then pumped to an unlined surface impoundment for storage and evaporation. After treatment, the wood was transported to a drip pad immediately south of the treatment vessel, where it was allowed to drip dry. In the early 1990s, HCC reportedly ceased using the drip pad; instead, the wood was allowed to dry inside the treatment vessel and was then moved to a transfer HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 12 area located at the end of the treatment vessel. The transfer area measured approximately 25 feet (ft) by 100 ft and consisted of soil and gravel over a plastic liner and covered by a metal roof. One 55-gallon sump was located at each end of the treatment vessel to contain any spills that occurred when the treatment vessel doors were opened. Spilled creosote was pumped back into the treatment vessel. A catch basin was also located at the end of the treatment vessel where the treated lumber was removed. The treatment vessel was cleaned from time to time due to buildup of creosote and solids. This sludge-like waste was removed and placed in 55-gallon containers that were stored in the drum storage area until they were shipped off Site for disposal. The surface impoundment, located at the southeastern corner of the facility, reportedly was 30 ft by 60 ft by 6 ft deep (approximately 80,000-gallon capacity) and was used by HCC to store liquid wastes until 1983. The surface impoundment contained waste classified as EPA hazardous waste K001: “bottom sediment sludge from the treatment of wastewaters from wood preserving processes that use creosote and/or pentachlorophenol.” Before 1981, HCC constructed a 0.587-acre landfarm on the east side of an unnamed tributary of North Deep Creek across from the operations area. Residual liquids from the surface impoundment were pumped to the landfarm, where an irrigation system was used to spray liquids onto the land surface. The landfarm was utilized when weather conditions did not allow for evaporation in the surface impoundment and when the surface impoundment was near its storage capacity. From 1982 to 1983, the landfarm was used as a remediation unit for disposal of K001-contaminated sludge and wastewater removed during closure of the surface impoundment. Key Physical Aspects of the Site Yadkin County lies within the northwestern portion of the Piedmont physiographic province just east of the Blue Ridge physiographic province. The Blue Ridge and Piedmont geologic provinces are large composite thrust sheets of folded and faulted rocks that were transported tens to hundreds of miles to the northwest during three Paleozoic mountain-building events. The exposed rocks now are, for the most part, the roots of an ancient mountain chain that consist of primarily igneous and metamorphic rocks with lesser amounts of sedimentary rocks. Lithologies identified during previous soil boring and monitoring well installation at the Site are non-native/remolded fill, alluvium, saprolite, partially weathered rock (PWR), and metamorphic bedrock. These lithologic features are discussed below: • Non-native/remolded fill. Fill material in the form of a thin (approximately 1 to 2 ft thick), orange-brown silty clay was deposited on the Site following an EPA-led removal of contaminated soils during 2011. This surface “cap” covers HCC from Highway 601 to the west to within approximately 10 ft of an unnamed tributary of North Deep Creek to the east. A similar clay covers the hilltop near the closed Resource Conservation and Recovery Act landfarm to the east of the unnamed tributary. Additional remolded soils are present near the process buildings, likely remnants of Site construction and grading. • Alluvium. Alluvial sediments/soil are present flanking the present stream channel of the unnamed tributary of North Deep Creek. Alluvial materials consist of graded beds of clay, silt, quartz, lithic and mica sands/gravels, and entrained organic/vegetative matter. The HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 13 historic stream channel appears to have been broader than its present course, extending west toward the facility buildings. Reduction in the stream channel breadth is the result of backfill with remolded soil. Such fill materials cover the western margin of the unnamed tributary channel to a depth of approximately 5 ft. • Saprolite. Saprolitic soil at the Site was derived from in-place chemical weathering of the native metamorphic bedrock. Site-specific geology descriptions from the Remedial Investigation (RI) and Feasibility Study reports describe the saprolite as a predominantly clay matrix with abundant vermiculite and other silt to sand-sized micaceous phases and angular quartzite sand lenses. Soil descriptions from the pre-RD soil borings indicate higher than expected content of silt, sand, and gravel in the saprolite. Pre-RD saprolite soil samples submitted for geotechnical laboratory analysis were classified as either silty sand or sandy silt. • PWR. The saprolite transitions to an underlying weathered gneiss unit, identified in previous site reports as PWR. The transition from saprolite to PWR occurs at relatively consistent elevations of between 835 to 845 ft North American Vertical Datum of 1988 (NAVD88) over most of the western portion of the Site, generally west of the unnamed tributary. The upper portion of the PWR is highly weathered gneiss that consists of moderately dense, fine to coarse-grained silty sand that is gray, white, and black in color. The PWR becomes increasingly dense with depth until it transitions to the underlying competent metamorphic bedrock. • Metamorphic bedrock. Bedrock identified at the Site consists of biotite and amphibolite gneisses with varying concentrations of purple garnet. Foliation dips from near horizontal to approximately 20°, with localized foliation discontinuities at small-scale folds and faults. Only a limited number of previous Site borings have been advanced into the bedrock. Review of the previous boring logs indicates that the top of competent rock is generally found at elevations of between 820 to 830 ft NAVD88. A characteristic feature of the region is the prevailing mantle of residual soil and saprolite that covers the bedrock in most places. This mantle of weathered bedrock comprises chiefly sandy clay, although fragments of solid rock are common near the bedrock surface. The thickness of this mantle frequently ranges from about 6 ft to 60 ft, though it is absent in many places and thicker than 60 ft in others. The mantle provides a recharge and discharge zone of water from the underlying fractured bedrock. Igneous and metamorphic rocks and consolidated sedimentary deposits of the region tend to be fractured to some extent, and these fractures are the chief avenues for water movement. Water level measurements collected during the RI and pre-RD investigation indicate that groundwater flow direction within the saprolite zone is generally toward the southeast. The flow direction is slightly more to the east-southeast in the PWR, and more eastward in the bedrock. Water levels measured during the RI and pre-RD investigation ranged from 0 to 25.14 ft below ground surface (bgs), mainly driven by changes in Site topography. Slug tests conducted during the RI produced average geometric mean hydraulic conductivities of 10.29 feet per day (ft/day) for the saprolite and 0.69 ft/day for the PWR. Packer testing of fracture zones in the bedrock resulted in relatively low permeabilities ranging from 0.05 to 0.35 ft/day. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 14 An unnamed tributary of North Deep Creek flows from north to south through the Site. The unnamed tributary begins north of the HCC property, flows in a southerly direction, and enters the Site along the northern property boundary. The stream continues to flow south along the eastern edge of the former HCC operations area and closed surface impoundment, then turns to the east before discharging into Dobbins Pond via a wetland. Dobbins Pond extends to the east and south of the Site for approximately 0.5 mile, where the unnamed tributary exits the eastern side of the pond via a rock weir. After exiting Dobbins Pond, the flow of the unnamed tributary continues for approximately 1 mile, where it discharges into North Deep Creek. Previous Investigations and Remedial Actions Surface Impoundment Closure Environmental activities were initiated in October 1982, when HCC notified the North Carolina Solid and Hazardous Waste Branch (currently known as the NCDEQ) of its intent to close the surface impoundment. From December 1982 to January 1983, HCC conducted closure activities for the surface impoundment, in accordance with a closure plan approved by the NCDEQ. Closure activities included the following: • Removing approximately 70,000 gallons of wastewater and spraying it onto the landfarm; • Excavating approximately 250 cubic yards of K001 sludge and contaminated soil and emplacing it within the landfarm; • Backfilling the former surface impoundment with clean soil; and • Re-grading and vegetating the surface of the impoundment. Closure of the surface impoundment was certified in April 1984. According to the closure plan, the surface impoundment was covered with a 2-ft clay cap and 1-ft vegetative cover (clean soil with grass). In July 2011, EPA excavated the vegetative cover over the surface impoundment down to the cap, disposed of the excavated material off-Site, and replaced it with clean soil because of confirmed contamination in the impoundment cover. The cap was verified to be present; however, the thickness and permeability was not confirmed. Landfarm Closure HCC initiated closure of the landfarm in 1983. During closure activities, soil samples were collected periodically at the landfarm to monitor the phenol degradation process. The closure plan outlined sampling and waste tillage procedures until sample analysis met the 15 parts per million phenol criterion. These procedures were followed until December 1983, when the samples met the phenol criterion, and a closure certification application was filed with the NCDEQ. However, NCDEQ’s review of the closure certification application raised concerns regarding chemical constituents other than phenol potentially present in the K001 waste stream. Samples subsequently collected from the landfarm contained creosote constituents, and NCDEQ ruled that these compounds had to be reduced to nondetectable levels prior to issuing a certification of closure for the landfarm. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 15 In August 1985, HCC was notified that additional landfarming would be required due to the presence of creosote constituents in soil. HCC and NCDEQ entered into a Consent Order and initiated a compliance schedule to further reduce creosote constituents. The consent order was voided by the NCDEQ in October 1985. In June 1986, HCC and NCDEQ entered into a revised Consent Order that allowed for continued landfarming of the K001 waste to achieve additional biodegradation of creosote and other regulated constituents. In April 1988, HCC notified NCDEQ that final analytical testing of the landfarm soil indicated that the performance standard for polynuclear aromatic hydrocarbons (PAHs) had not been met, and thus, the landfarm could not be certified as closed. As a result, the landfarm was closed as a landfill (hazardous waste in place), in accordance with a closure plan approved by NCDEQ. A 2-ft thick clay cap was placed over the landfarm and installed to extend a minimum of 3 ft beyond the known boundary of the landfarm. A ditch was constructed around the landfarm area to control stormwater runon and runoff. A 1-ft thick vegetative cover (topsoil and grass) was installed above the clay cap. The landfarm was certified closed in September 1989. EPA sampling activities conducted in 2011 and between 2012 and 2014 found that the landfarm cap consists of approximately 2 ft of red, clay-like material and that the 1-ft vegetative cover is not present. The permeability of the cap material has not been evaluated. Groundwater Assessment Groundwater monitoring at HCC began in 1982 with installation of three monitoring wells in the shallow saprolite aquifer near the operations area and surface impoundment. Following closure of the surface impoundment and construction of the landfarm, additional wells were installed in the suspected downgradient (southeast) corner of the surface impoundment and around the landfarm perimeter. By 2002, the groundwater monitoring network consisted of 16 monitoring wells completed in the saprolite, PWR, and bedrock aquifers beneath the facility. The monitoring wells were sampled annually from 1995 to 2005. Monitoring wells located within and near the backfilled surface impoundment contained the highest concentrations of Site-related contaminants throughout the 10-year sampling history. The primary constituents detected were PAHs and petroleum volatile organic compounds, potentially originating from creosote and/or diesel oil used and stored at HCC in the past (diesel oil was used to dilute the creosote mixtures). Violations and Post-Closure Permit From 1992 to 2002, HCC was issued several notices of violation (NOVs) including the following: • Failure to control runon in the area of the closed surface impoundment; • Failure to follow its post-closure Sampling and Analysis Plan; • Failure to determine whether solid waste generated at HCC was a hazardous waste; • Failure to obtain a permit for storage and disposal of waste creosote; and • Failure to treat, store, and dispose of hazardous waste in compliance with state and federal regulations. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 16 Around 1994, HCC stopped generating K001 waste and began generating EPA hazardous waste F034 defined as “wastewaters, process residuals, preservative drippage, and spent formulations from wood preserving processes generated at plants that use creosote formulations.” HCC was issued a Post-closure Hazardous Waste Management Permit by NCDEQ in September 1995. The permit required HCC to maintain post-closure care of the closed surface impoundment and landfarm and to conduct groundwater monitoring and remedial activities at the facility including installation of a wastewater treatment system. In 2005, HCC submitted a renewal application for the Post-closure Hazardous Waste Management Permit; however, the permit was not granted due to numerous deficiencies. In 2007, NCDEQ issued a Post-closure Hazardous Waste Management Renewal Permit to HCC. The permit included requirements for continued post-closure care of the surface impoundment and landfarm, and also identified eight solid waste management units requiring a Resource Conservation and Recovery Act (RCRA) Facility Investigation. NCDEQ Inspection HCC ceased wood treating operations on the property in February 2009. In November 2009, NCDEQ conducted an inspection of the facility and noted several areas of concern including the treatment vessel, 55-gallon sump, catch basin, transfer area and underlying soils, concrete storage pit, aboveground storage tanks, and approximately thirty 55-gallon containers. As a result, several NOVs were issued by NCDEQ to HCC, including: • Failure to determine whether solid waste generated at HCC was a hazardous waste; • Failure to obtain a permit for storage and disposal of waste creosote; and • Failure to treat, store, and dispose of hazardous waste in compliance with state and federal regulations. EPA Site Inspection and Removal Actions In January 2011, EPA conducted a removal site evaluation at the request of NCDEQ. EPA noted the following: • Heavily stained soil throughout the process area; • Waste creosote and process sludge in the concrete storage pit; • A leaking 1,000-gallon aboveground storage tank; • Two 10,000-gallon creosote tanks containing approximately 5,600 and 8,500 gallons of creosote; and • A visible sheen in the unnamed tributary of North Deep Creek. As a result, EPA initiated an emergency response to mitigate the ongoing release of hazardous substances. Response activities were conducted between January and September 2011 and included the following: HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 17 • Installation of a sorbent boom across the unnamed tributary of North Deep Creek to capture visible sheen; • Disposal of approximately 120 cubic yards of creosote-treated lumber; • Excavation and off-Site disposal of approximately 1,600 tons of contaminated soil; and • Removal of six facility process units (process area structures) containing creosote sludge. EPA also conducted investigation activities in January 2011 during the emergency response and between May and August 2011 as part of a Site Inspection. The sampling activities included collection of soil and sediment samples along the unnamed tributary of North Deep Creek and within the wetlands at the confluence of the tributary and Dobbins Pond, surface soil samples from the vegetative cover of the former surface impoundment, subsurface soil samples in the vicinity of the closed landfarm, and groundwater samples from all Site monitoring wells. EPA also completed a wetlands delineation study at HCC in August 2011. As a result of the sampling activities and observations during the emergency response activities, additional Removal Actions were completed at HCC, including the following: • Excavation and off-Site disposal of the vegetative cover of the closed surface impoundment down to the clay cap. The clay cap was confirmed to be present, but its thickness and permeability were not evaluated. The area was backfilled with clean soil. • Removal and off-Site disposal of soil along the unnamed tributary of North Deep Creek. • Removal and off-Site disposal of approximately 2 inches of sediment from 300 linear ft of the channel bottom and sidewalls of the unnamed tributary of North Deep Creek. • Installation of fencing to limit trespassing and contact with contamination associated with the backfilled surface impoundment and surficial sediments in the unnamed tributary of North Deep Creek. • Excavation of the upper 1 ft of soil from the northern portion of the former process area. • Removal and backfill of the concrete storage pit. Figure 3 summarizes the extent of the removal action activities including the extent of the excavated depths and confirmation sample locations. Remedial Investigation An EPA-led RI was conducted for the HCC Site between 2012 and 2017. A complete discussion of nature and extent can be found in the Final Remedial Investigation Report (Versar, 2017). Selected Remedy EPA issued a ROD in August 2018 that established cleanup goals for soil, sediment, and groundwater, and selected a remedy for the Site. The Site cleanup goals are summarized in Table 1. The selected remedy includes the following components: HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 18 • Excavation of contaminated soil outside of the previously closed and capped landfarm and surface impoundment areas, and proposed containment area, as required, to mitigate human exposure and additional leaching of contaminants into the surficial aquifer. The excavated areas will be backfilled with uncontaminated soil obtained from an off-Site borrow source. The excavated wetlands will be restored. • Disposal of excavated soil in an on-Site capped containment cell, which is proposed to be located within the former operations area. Excavated soils/sediments impacted with non-aqueous phase liquid (NAPL) will be treated within the containment area using in situ solidification/stabilization technology to reduce the mobility of contaminants of concern (COCs) by eliminating free liquids and to stabilize the containment cell. The proposed containment cell will be capped using a RCRA-type multi-layered cap that meets the RCRA Subtitle C landfill requirements for a final cover. • Maintenance of the existing RCRA caps over the closed landfarm and surface impoundment including regrading, repair, and revegetation. These areas also will be fenced to restrict access. A review of Site conditions and risks will be conducted every 5 years as long as contamination remains on Site above levels that allow for unlimited use and unrestricted exposure. The caps will be inspected at least annually, and repairs will be made when needed. • In situ groundwater treatment of groundwater using in situ geochemical stabilization (ISGS) and/or in situ chemical oxidation (ISCO) to reduce concentrations of COCs to below cleanup levels. Bench-scale and pilot-scale tests were conducted during the RD to confirm the effectiveness of the treatment technologies and to determine appropriate injection rates, injection concentrations, activator selection, and injection well spacing. The collection of post-treatment groundwater samples will be needed to assess the effectiveness of the ISGS and ISCO treatment. • In situ enhanced bioremediation (ISEB) using a reagent such as slow release calcium peroxide will be implemented after the ISCO/ISGS treatment in remaining areas with elevated groundwater COC concentrations. A pilot-scale test was performed during the RD to select the appropriate ISEB reagents. The goal of the in situ treatments is the restoration of groundwater throughout the plume beyond the waste management areas to attain federal as well as more stringent state drinking water standards based on the designated beneficial use of the aquifer as a potential drinking water source. • Groundwater monitoring will be implemented to verify the effectiveness of the containment system, soil stabilization, and groundwater treatment. Data collected from the monitoring wells will be evaluated to determine if additional injections of treatment reagents are required to treat the groundwater. The monitoring well network will be expanded to include additional wells downgradient of the containment cell, as necessary. Groundwater monitoring wells will be added, as needed, outside of the containment unit boundary to assess if there are any releases from the unit. • Institutional controls and engineering controls will be implemented to preserve the integrity of the remedy and restrict land use to eliminate or reduce the potential for unacceptable human health risks from exposure to contamination. Institutional controls will be used to restrict future use of the property to industrial/commercial uses in areas HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 19 that do not allow for unrestricted access and use, prohibit excavation and construction over the capped area, prohibit the installation of new water supply wells within the plume area, and prohibit the use of groundwater for drinking water supply within the plume area. Engineering controls, such as fencing, will be placed around the containment cell, closed landfarm, and closed surface impoundment. Regular inspections will be performed to verify the continued implementation of the groundwater use restrictions and the integrity of the engineering controls and RCRA caps. The results of the ISGS/ISCO and ISEB pilot-scale tests indicated that ISGS/ISCO is less effective than ISEB. Accordingly, the Final (100%) Groundwater Remedial Design included only ISEB as the groundwater remedy (HGL, 2022). However, since ISGS would not be used treat NAPL below the water table, in situ solidification/ stabilization (ISS) was added to the Final (100%) Soil Remedial Design (HGL, 2021). Pre-RD Investigation In February 2020, a North Carolina-licensed professional land surveyor (Donaldson, Garrett & Associates, Inc.) performed a topographic survey to document Site topography, existing conditions, property boundaries, and Site features. The survey was referenced horizontally to the North Carolina State Plane Coordinate System, North American Datum of 1983, and vertically to the NAVD88. Horizontal accuracy was within ±0.1 ft; vertical accuracy was within ±0.01 ft. In February 2020, 47 existing Site groundwater monitoring wells were sampled to provide groundwater concentration data for the selection of new monitoring well locations. In March 2020, two permanent saprolite monitoring wells, five permanent PWR monitoring wells, and one temporary PWR monitoring well were installed. The temporary PWR monitoring well was abandoned so it would not interfere with the agricultural usage of the field where it was located. Results from the groundwater investigation were used to further delineate the horizontal extent of naphthalene contamination greater than the North Carolina groundwater standard of 6 micrograms per liter (µg/L) and to assist in defining the groundwater treatment areas. In February, August, and October 2020, a total of 50 surface soil samples and 129 subsurface soil samples were collected. Results from the soil investigation were used to define the extent of naphthalene concentrations greater than the Site-specific groundwater protection value of 180 micrograms per kilogram (µg/kg) in unsaturated soils above the water table and to evaluate the presence and extent of NAPL. In August and October 2020, a total of five sediment samples were collected. Results from the sediment investigation were used to define the extent of PAH concentrations greater than the maximum acceptable toxicant concentration of 198 milligrams per kilogram (mg/kg) total PAHs. In February 2020, a source area NAPL investigation was conducted to evaluate the presence and extent of NAPL in the Site source areas using Tar-specific Green Optical Screening Tool (TarGOST®) laser-induced fluorescence soil logging technology. In total, 40 TarGOST® borings were advanced via direct-push technology (DPT) to refusal, at the 38 locations. At two locations, duplicate offset borings were performed for field quality control purposes. The TarGOST® borings included 23 initial locations selected based on historical Site operations and previous analytical HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 20 results and 15 step-out locations selected in the field to delineate potential NAPL. After field review of TarGOST® logs, locations were selected for offset exploratory borings to visually confirm potential TarGOST® NAPL detections. Exploratory borings were advanced to DPT refusal at nine locations adjacent to TarGOST® locations In March 2020, nine geotechnical soil borings were drilled to collect geotechnical data needed to design the soil excavations and containment cell. The nine borings were drilled by hollow stem auger with continuous standard penetration testing from ground surface to the top of the PWR. The boring locations were selected along three transects with three borings in each transect, as follows: • Transect 1 was located directly behind the Site building and extended to the east toward the unnamed tributary. • Transect 2 was located between the closed landfarm and the unnamed tributary and was north-south trending. • Transect 3 was also located between the closed landfarm and the unnamed tributary and was northwest-southeast trending. Along each transect, one boring was drilled near the top of the slope, one was drilled mid-slope, and one was drilled near the bottom of the slope. One composite bulk sample of soils above the water table was collected from each transect and submitted to a subcontracted geotechnical laboratory for analysis by the following test methods: • Unified Soil Classification System soil classification by ASTM D2487, • Moisture content by ASTM D2216, • Atterberg limits by ASTM D4318, • Moisture-density relationship by ASTM D698, and • Unconfined compressive strength by ASTM D2166. In addition, two saturated soil samples from below the water table were collected within the potential groundwater treatment areas for laboratory measurement of bulk density. The saturated soil samples were collected from the borehole of monitoring well MW-49 (located in the impoundment area co-located with TarGOST® boring HCTG06) and from the top of slope geotechnical boring HCGT-1A, located within Transect 1. In March 2020, an asbestos and lead-based paint inspection and assessment was performed by a certified North Carolina inspector. The existing Site building was inspected, and samples were collected, as needed, by the inspector to determine the presence of asbestos-containing material (ACM) (including friable and Category I and Category II nonfriable ACM), lead pipes, and/or lead-based paint. The results of the inspection indicated that the following items tested positive for the presence of ACM: • Window putty on four steel windows, • Roofing materials on the flat roof portion of the building, HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 21 • Grey-black tar placed around the chimney on the flat roof, • Grey-black tar placed around pipe intrusions through the lower metal roof, and • Tar located under part of the flat roof. Lead was found in ceramic tile glaze surrounding cabinets in one of the rooms of the building. Lead-containing paint was found on several interior and exterior painted surfaces throughout the building. The following subsections present a summary of the nature and extent of contamination at the Site as evaluated during the RI and pre-RD investigation. Sources of Known or Suspected Hazardous Waste Sources of contamination at HCC are related to the former operations areas and landfarm areas. Specific source areas based on the historical data include the following: former concrete storage pit, former surface impoundment, underground storage tanks, 55-gallon sump, and catch basin. Figure 2 provides a layout of the historical site features. Known or Suspected Contaminants or Classes of Contaminants Semivolatile organic compounds, mainly PAHs, are present in soils throughout the former operations area, the landfarm, and the southern portion of the unnamed tributary before entering the wetlands. Naphthalene is the main COC in the groundwater; however, there are co-mingled plumes of other COCs including dibenzofuran, cobalt, manganese, iron, and 2-methylnaphthalene. Primary Release Mechanisms Creosote stored and used at the Site either leaked or was spilled on the ground during HCC operations. Waste liquids containing creosote and dissolved COCs from the wood treating process were contained in on-Site sumps and a concrete storage pit and discharged an unlined surface impoundment. Water from the surface impoundment was sprayed onto the landfarm area; the landfarm area was also used for disposal of sludge excavated from the surface impoundment during its closure. Secondary Contaminant Migration Contaminants in soils and sediment can migrate through overland flow in rainwater runoff and surface water flow when contaminants are adsorbed to suspended sediment. Dissolved COCs directly discharged to the groundwater from the former unlined surface impoundment or which enter groundwater through desorption from soil will flow in the direction of groundwater as a function of the local horizontal and vertical gradient. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 22 Land Use Considerations Land uses surrounding the HCC property are predominantly agricultural, residential, and light industrial. The Site property is currently vacant. Future uses of the Site property are expected to be restricted to industrial/commercial. Potential Receptors and Exposure Pathways Potential receptor populations could include trespassers, anglers fishing in Dobbins Pond, and potential future on-Site workers. Potentially complete exposure pathways include incidental ingestion of soil, dermal contact with soil, inhalation of particulates released from soil, ingestion of groundwater, inhalation of vapors released from groundwater, and ingestion of fish. Current Interpretation of the Nature and Extent of the Contamination An EPA-led RI was conducted for the HCC Site between 2012 and 2017. An EPA-led pre-RD investigation was conducted in 2020. The following subsections present a summary of the nature and extent of contamination at the Site as evaluated during the RI. A complete discussion of nature and extent can be found in the Final Remedial Investigation Report (Versar, 2017), the Final Groundwater Data Evaluation and Conceptual Site Model Update Technical Memorandum (HGL, 2020a), the Final Soil Data Evaluation and Conceptual Site Model Update Technical Memorandum (HGL, 2020b), and the Final 100% Soil Remedial Design (HGL, 2021). Suspected Source Areas Sources of contamination at HCC are related to the former operations areas and landfarm areas. Specific source areas based on the historical data include the following: former concrete storage pit, former surface impoundment, underground storage tanks, 55-gallon sump, and catch basin. Figure 2 provides a layout of the historical Site features. Soil Contamination Semivolatile organic compounds, mainly PAHs, are present in soils throughout the former operations area, the landfarm, and the southern portion of the unnamed tributary before entering the wetlands. Benzo(a)pyrene and naphthalene are the main COCs in soil. The extent of soil contamination is generally defined by the extent of naphthalene exceeding its Site-specific groundwater protection value of 180 µg/kg. Figure 4 depicts the RI and pre-RD investigation soil sampling locations and identifies locations where naphthalene was detected above 180 µg/kg. Sediment Sediment samples were collected during the RI and pre-RD investigation from Dobbins Pond, the unnamed tributary, and the wetlands. The only COC identified in sediment was total PAHs. Only one sediment sample, HCSD47 located in the wetlands just south of the landfarm, exceeded the maximum acceptable toxicant concentration of 198 mg/kg total PAHs calculated from Site- specific soil invertebrate toxicity testing (shown on Figure 4). HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 23 Groundwater Naphthalene is the main COC in the groundwater; however, there are co-mingled plumes of other COCs including dibenzofuran, cobalt, manganese, iron, and 2-methylnaphthalene. Groundwater contamination is most prevalent in the saprolite and PWR in the area between the east and southeast sides of the main building and west side of the unnamed tributary. There is very little groundwater contamination near the landfarm or in the bedrock. The extent of groundwater contamination is generally defined by the extent of naphthalene exceeding its North Carolina groundwater standard of 6 µg/L. Figures 5 and 6 depict the RI and pre-RD investigation groundwater sampling locations and identifies locations where naphthalene was detected above 6 µg/L in the saprolite and PWR, respectively. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 24 WORKSHEET #11 PROJECT/DATA QUALITY OBJECTIVES This worksheet develops the DQO for the HCC Site using a systematic planning process in accordance with EPA QA/G-4, Guidance on Systematic Planning Using the Data Quality Objectives Process (EPA, 2006). The DQOs are developed separately below. 1. State the Problem. As described in Worksheet #10, soil, sediment, and groundwater at the Site are contaminated with naphthalene, PAHs, and other creosote-related compounds from past wood treating operations at the Site. Additional soil data are needed to fully define the extent of contamination above cleanup levels and to support separate soil and groundwater RAs in accordance with the Site’s ROD. Soil/sediment concentrations above the Site cleanup levels will be included in the RA excavation areas; however, soil/sediment concentrations below cleanup levels will not. Similarly, groundwater concentrations above the Site’s cleanup levels will be included in the RA groundwater treatment zones; however, groundwater concentrations below the cleanup levels will not. In addition, geotechnical data are needed to evaluate the quality control of the soil RA solidification/stabilization (S/S) and ISS. 2. Identify the Goals of the Project. The goals of the soil field investigation are as follows: 1) Define the extent of naphthalene concentrations greater than 180 µg/kg in surface and subsurface soils above the water table in the following locations: i. Near the unnamed tributary ii. Near Excavation Area 5 iii. At and around soil boring HCSB113 iv. At and around soil boring HCSB141 v. At and around soil boring HCSB175 2) Perform quality control of the soil RA S/S and ISS. 3. Identify Information Inputs. The information inputs will consist of previous Site data collected during the RI and pre-RD investigation and data from new soil samples that will be collected from the Site during the pre-RA investigation. Data from the RI and pre-RD investigation is considered acceptable for use because it was collected and analyzed in accordance with the EPA’s standard operating procedures (SOPs) and meets the DQOs. Soil samples will be collected from the 17 proposed locations shown on Figures 7a and 7b and submitted to a designated CLP laboratory for analysis of PAHs with Selected Ion Monitoring (SIM), unless NAPL or gross contamination is present. Samples exhibiting the presence of NAPL or gross contamination will be submitted to the EPA Region 4 laboratory for analysis of PAHs without SIM. Quality control samples will be submitted to a geotechnical laboratory for testing of unconfined compressive strength (UCS) of soil-cement by ASTM D 1633 and flexible wall permeability by ASTM D 5084. Tasks required to collect, evaluate, and manage project data are summarized on Worksheets #14 and #16. 4. Define the Boundaries of the Study. The boundaries of the HCC Site (Figure 2) will be the study limits. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 25 5. Develop the Analytic Approach. Sampling and analysis tasks are outlined in Worksheets #14 and #16. HGL will perform technical review and evaluation of the analytical data and reports to support the RA. Point data obtained from the sample results will be compared to the Site cleanup levels that were established by the ROD and identified as the project action limits (PALs) on Worksheet #15. Statistical averaging will not be used to compare the Site data to the PALs. 6. Specify Performance or Acceptance Criteria. Analytical QC data associated with project sample results will be compared to the measurement performance criteria of each data quality indicator (DQI) listed on Worksheet #12 to determine data quality and whether sample results are acceptable based on the established DQOs. The PALs and quantitation limits (QL) are specified on Worksheet #15. Analytical data will be compared to these limits. 7. Develop the Detailed Plan for Obtaining Data. The specific project tasks and schedule for data collection are located in Worksheet #14 and 16. Details on the sampling locations and field sampling procedures are presented in Section 3.0 of the Volume 1 FSP (Appendix A). HGL will be responsible for all sample collection, shipment, and management and will coordinate with the EPA RSCC to obtain the laboratory assignments. Samples will be submitted to the laboratory assigned by the RSCC, and validated data will be provided by EPA. Validation criteria is included in Worksheets #34, #35, and #36, and data usability is included in Worksheet #37. Definitive data will be required for all data that will be used for comparison to PALs. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 26 WORKSHEET #12 MEASUREMENT PERFORMANCE CRITERIA Measurement performance criteria are expressed in terms of data DQIs. DQIs are qualitative and quantitative descriptors used to interpret the degree of acceptability or usability of data. The principal DQIs are precision, accuracy (or bias), representativeness, completeness, and comparability. Of the five DQIs, precision and accuracy are the quantitative measures, representativeness and comparability are the qualitative measures, and completeness is a combination of quantitative and qualitative measures. For this investigation, sample analyses for definitive-level data requirements will be performed by the EPA Region 4 and/or CLP laboratories. CLP laboratories are required to comply with the (1) CLP methods specified in Organic Superfund Methods, Multi-Media, Multi-Concentrations (SOM02.4) prepared by the EPA in October 2016 (EPA, 2016); (2) Superfund Analytical Methods, Multi-Media, Multi-Concentration (SFAM01.1) prepared by EPA in November 2020 (EPA, 2020a); and (3) High Resolution Superfund Methods, Multi-Media, Multi-Concentration (HRSM02.1) prepared by the EPA in November 2020 (EPA, 2020b) that include stringent QA/QC requirements to ensure data reported by the laboratory meets measurement quality objectives (EPA, 2016; 2020a; and 2020b). The EPA Region 4 laboratory is required to comply with its Laboratory Operations and Quality Assurance Manual (LOQAM) (EPA, 2021) as well as internal SOPs. The EPA Region 4 LOQAM is included as Appendix C. The assessment of laboratory-related DQIs is performed by the laboratories and during data validation. For this RA field investigation, the EPA Region 4 will perform data validation. The data validators will review the laboratory’s QC measures required by the Region 4 LOQAM or CLP statement of work (SOW) and the analytical method, including method procedures, internal spikes, calibrations, matrix spikes (MS), matrix spike duplicates (MSD), and performance evaluation samples, and place qualifiers on the data as appropriate. The narratives included in the data deliverable reports will identify and discuss any qualifiers placed on the data during the data validation process. Evaluation of field-related DQIs is performed by the sampling contractor after receipt of the validated data from EPA. The sampling contractor evaluates field precision, completeness, and representativeness, as discussed below. Field Precision Field precision is assessed by collecting and measuring field duplicates at a rate of 1 duplicate per 20 environmental samples. Precision will be assessed through calculation of relative percent difference (RPD). The formula for calculating RPD is as follows: 𝑅𝑃𝐷=|𝑅−𝐷| (𝑅+𝐷) 2 𝑥100 where: S = first sample value (original sample value); and D = second sample value (duplicate sample value). HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 27 RPDs of less than 50% for soil sample duplicates will be the field precision objectives for this investigation. Sample duplicate RPD failures are implications of sample collection errors and should warrant a review of sample collection. Field Completeness Field completeness is defined as the percentage of analytical results obtained compared with the projected number of analytical results that would be obtained from all planned sample locations. The formula for calculating sampling completeness is as follows: Field Completeness = Number of Data Points Obtained X 100% Number of Planned Data Points The field completeness objective for this project will be greater than 90%. Field Representativeness Representativeness is the degree to which data accurately and precisely expresses a characteristic of a population, parameter variations at a sampling point, or an environmental condition. Representativeness will be qualitatively assessed using the results of field blank samples, such as equipment rinsate blanks (EBs), that will be collected to assess potential contamination due to field conditions. The assessment of blank samples will evaluate if compounds detected in the environmental samples are Site-related or have been introduced through shipping, storage, or field procedures.

A well-developed sampling design plays a critical role in ensuring that data are sufficient to draw the conclusions needed. A complete sampling design indicates the number of samples, identifies their locations, and includes an explanation and justification (rationale) for the number and the locations of the samples. There are two main categories of sampling designs: probability- based designs and judgmental designs. Probability-based sampling designs apply statistical theory and involve random selection of sampling locations. When a probability-based design is used, statistical inferences may be made about the entire study area using the data obtained from the randomly selected sampling locations. Judgmental sampling designs involve the selection of sampling locations based on site knowledge or professional judgment and are most applicable where existing site knowledge or data are available to guide and inform the sampling design, as presented in Guidance on Choosing a Sampling Design for Environmental Data Collection for Use in Developing a Quality Assurance Project Plan (EPA, 2002). At the HCC Site, a judgmental sampling design will be used to accomplish the sampling objectives. Sufficient Site knowledge and data are available from previous investigations including the known locations of contamination, as needed, to develop a judgmental sampling approach to evaluate the extent of contamination. The design and rationale for the field sampling activities is provided below. Refer to Section 3.0 of the FSP (Appendix A) for further details on field sampling procedures. The sampling process was designed to ensure that the sampling objectives are fulfilled in support of the RA. The objective of the RA field investigation is to further characterize the extent Site- related soil contamination above ROD cleanup in surface and subsurface soil. In addition, geotechnical data are needed to evaluate the quality control of the soil RA S/S and ISS. To accomplish these objectives, HGL will perform sampling activities in the following areas: • Near the unnamed tributary, • Near Excavation Area 5, • At and around soil boring HCSB113, • At and around soil boring HCSB141, and • At and around soil boring HCSB175. Soil samples for laboratory analyses and quality control samples for geotechnical testing will be collected under this UFP-QAPP. The sampling design and rationale for each matrix to be sampled is discussed below. The sampling design that follows has been developed based on the results of previous Site investigations and input from EPA. The design describes the sampling rationale and approach and includes the number, types, and locations of samples to be collected and the methods of analyses to be performed. Refer to Worksheet #18 and Table 3.1 of the FSP (Appendix A) for a summary of proposed soil samples, rationale for each sample location, and associated chemical analyses for this investigation. HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 34 Soil Sampling The Conceptual Site Model presented in Worksheet #10 identifies data gaps that need to be addressed to further delineate Site-related soil contamination. Soil sampling will be conducted in the following areas of the Site: • Near the unnamed tributary: Soil samples will be collected to delineate soil contamination east of HCSB102 and HCSB172. Soil samples will be collected from 0 to 0.5 ft bgs at three locations just west of the unnamed tributary. • Near Excavation Area 5: Soil samples will be collected to delineate soil contamination south of HCSB134. Soil samples will be collected from 0 to 0.5 ft bgs at two locations, southeast and southwest of HCSB134. • HCSB113: As part of the ISS plan, naphthalene-contaminated overburden soil above the water table will be excavated and placed in the Site containment cell. However, at ISS Area F, north of the surface impoundment, the elevated naphthalene concentrations detected at soil boring HCSB113 at 4 to 8 ft bgs are possibly the result of NAPL in the sample. Overburden soil above the water table at Area F will be re-sampled to determine whether a portion of it can be segregated as clean backfill. Soil samples will be collected at 2 to 4 ft bgs and 4 to 6 ft bgs at HCSB113. Four additional soil samples will also be collected at 2 to 4 ft bgs and 4 to 6 ft bgs from two step-out soil borings north and west of HCSB113. • HCSB141: One soil sample will be collected at 8 to 10 ft bgs to confirm the soil contamination at HCSB141, near US Highway 601. Additionally, cutline soil sampling will be conducted around HCSB141. Eight additional soil samples will also be collected at 8 to 10 ft bgs and 10 to 12 ft bgs from four step-out soil borings north, south, east, and west of HCSB141. • HCSB175: Cutline soil sampling will be conducted around HCSB175. Eight additional soil samples will also be collected at 2 to 5 ft bgs and 5 to 7 ft bgs from four step-out soil borings north, south, east, and west of HCSB175. The rationale for the boring locations is presented on Table 3.1 of the FSP. The soil samples will be collected using DPT or decontaminated hand augers in accordance with the procedures presented in the FSP (Appendix A). All soil samples will be analyzed for PAHs with SIM. Geotechnical QC Testing QC samples for laboratory testing of UCS will be performed on mixed and cured samples at a frequency of two samples per mixing zone. There are 6 zones: Area A; Area B; Areas C & D; Area E; Areas F & G; and the stabilization pit, for a total of 12 samples for the total volume of soils to be treated with S/S of 1,678 bank cubic yards (approximately 1 sample per every 140 bank cubic yards). For each sampling event, the RA Contractor will prepare the minimum number of replicate sample molds (coupons) for UCS testing at 7, 14, and 28 days, and reserve samples for permeability testing at 14 and 28 days. Information on sampling requirements is located in Specification 02 55 00 in the soil RD (HGL, 2021).

Each type of field QC sample undergoes the same preservation, analysis, and reporting procedures as the related environmental samples. Field Duplicates Field duplicates will be collected and analyzed for the identical chemical constituent list as the corresponding parent samples to measure the cumulative uncertainty (i.e., precision) of the sample collection, handling, storage, preparation, and analysis operations. Field duplicates are labeled as individual environmental samples and are not identified to the laboratory as duplicate samples. Field duplicates will be collected at a frequency of 1 per 20 investigative samples collected. Matrix Spikes MS samples are environmental samples to which known quantities of analytes are added by the laboratory before sample preparation (digestion or extraction). These are laboratory QC samples that provide information about the heterogeneity of the field samples as well as the effect of the sample matrix on the sample digestion and measurement methodology. MS samples will be collected at a frequency of 1 per 20 investigative samples collected. Matrix Spike Duplicates MSD samples are duplicates of MS samples and are used for estimating laboratory precision of target analyte analyses. An MSD sample will be collected for every MS sample collected. Temperature Blanks Temperature blanks are vials of water inserted into each sample cooler prior to being shipped from the field to the laboratory. The temperature of the temperature blank is measured upon receipt at the laboratory to assess whether samples were properly cooled during transit. One temperature blank will be included in every cooler shipped to the laboratory. Equipment Rinsate Blanks EBs will be collected at a frequency of one per day. For the HCC Site, EBs will be collected from the DPT tooling and sampling equipment (auger buckets, bowels, spoons, trowels) used for soil and sediment sampling. EBs, collected by routing deionized water (for inorganic analyses) or organic-free water (for organic analyses) through decontaminated sampling equipment, will be analyzed to check procedural decontamination, ambient conditions, and/or sample container contamination. EB descriptions will be recorded in field logbooks or sample log forms and will state what equipment was used to prepare the rinsate. The ID of field QC samples will follow the sample nomenclature presented in Worksheets #26 and #27. MS and MSD samples will be documented as “extra volume of laboratory QC” on the CoC form. 1 Samples with observed NAPL or gross contamination will be analyzed for routine PAHs without SIM.

Sample Handling Sample handling includes the field-related considerations connected with selecting sample containers, preservatives, allowable holding times, and analyses requested. Samples may be HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 44 unstable and therefore require preservation to prevent changes in either the concentration or the physical condition of the constituent(s) requiring analysis. Field Sample Preservation and Containers Samples collected for routine analytical services will be contained and preserved in accordance with the EPA Region 4 laboratory’s LOQAM (EPA, 2021). An outline of the necessary sample containers and preservation requirements can be found in Worksheets #19 and #30 and in Table 3.2 of the FSP (Appendix A). All sample containers used to collect samples will be procured from a supplier by HGL. The sampling containers will be purchased pre-preserved, where applicable. For chemical analyses, sample containers will be new and pre-cleaned, and certificates of cleanness will be required with each lot of containers. All sample containers will be prepared according to the procedures contained in Specifications and Guidance for Obtaining Contaminant-Free Sample Containers prepared by EPA in December 1992 (EPA, 1992). This document specifies the acceptable types of containers, the specific cleaning procedures to be used before samples are collected, and QA/QC requirements relevant to the containers and cleaning procedures. Field Sample Identification, Tracking, and Labeling Each collected sample will be assigned a unique sample ID number and will be collected from a unique station location. Previous sample locations that are being resampled must use the existing station location. Sample Identification Each sample collected will be assigned a unique sample ID number. Any other pertinent information regarding sample ID will be recorded in the field logbooks and/or sample log sheets. MS/MSD, blanks, and field duplicate samples will be designated on the field documentation forms, including the CoC. Station location identifies the sampling locations with an associated geographic coordinate. The well ID will be used as the station ID. The sample ID identifies each individual sample collected. Sample IDs will be assigned as follows: Re-sampling locations: RI samples being re-collected for confirmation of previous results will use the same station IDs as the original samples. Soil boring locations: HCSB2## where HC represents Holcomb Creosote, SB indicates a soil boring location, 2 indicates the pre-RD field investigation (to differentiate from RI locations), and ## is a sequential number beginning with 01. The sample ID identifies each individual sample collected. Sample IDs will be assigned as follows: Re-sampling locations: Samples being re-collected for confirmation of previous results will use the same sample IDs as the original samples. Soil borings – surface soil: SF will be added to the end of the station location (e.g,. HCSB201SF). HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 45 Soil borings – subsurface soil: -TDBD will be added to the end of the station location, where TD is the top depth of the sample in feet and BD is the bottom depth of the sample in feet [e.g., HCSB201-0810 for a sample collected from 8 to 10 ft at HCSB201]). Field duplicate samples will be identified by adding an “X” at the end of the sample ID. For example, a field duplicate of sample HCSB201-0810 would be identified as HCSB201-0810X. Other field QC samples collected during the investigation will be assigned sample IDs based on the following format: • Equipment Rinsate Blank: HCRBMMDDYY Where: HC = Holcomb Creosote RB = Equipment Rinsate Blank MMDDYY = the month (MM) day (DD) and year (DD) the sample was collected For example, an EB collected on December 10, 2022, would be identified as HCRB121022. QC samples, such as blanks and rinsates, will be given a station ID of #R4DART#. Sample Tracking and Management Samples will be tracked in the field using Scribe sample tracking software. Scribe will be used to manage sample collection, documentation, and submission of all relevant reports, including the CoC. Scribe will also be used to export the data to the EPA Region 4 EQuIS database, the EPA Region 4 Laboratory Information Management System, and the CLP Sample Management Office. Sample Labeling Sample labels will be generated with Scribe software. Sample labels will include the unique sample ID, collection date and time, sample type, matrix, analysis, and preservation method. The labels will be prepared using waterproof, non-erasable ink, as specified in the EPA Region 4 LSASD SOP SESDPROC-005-R3 Sample and Evidence Management. Sample labels will be prepared and affixed to each sample container sent to the designated EPA or CLP laboratory. Custody Seals The samples collected and containerized will be sealed as soon as possible following collection, as specified in EPA Region 4 LSASD Operating Procedure SESDPROC-005-R3 Sample and Evidence Management. The sample custodian will write the date and their signature or initials on the seal. Field Sample Packaging and Shipping Samples will be packaged and shipped in accordance the EPA Region 4 LSASD SOP LSASDPROC-209-R4 Packing, Marking, Labeling, and Shipping of Environmental and Waste Samples. In general, the following procedures will be followed when shipping samples for laboratory analysis: HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 46 • All samples require cooling to 4°C +/- 2°C and will be promptly chilled with ice and packaged in an insulated cooler for transport. Each cooler shipped to the laboratory will include a temperature blank. Ice will be sealed in containers to prevent water leakage. Samples will not be frozen. • The samples will be packed by placing cushioning/absorbent material in the bottom of the cooler and then placing the containers in the cooler with sufficient space to allow for the addition of cushioning between the containers. • Only shipping containers that meet all applicable federal standards for safe shipment will be used. • Shipping containers will be sealed with shipping tape, and custody seals will be signed, dated, and affixed in a manner that will allow the receiver to quickly identify any tampering that may have occurred during transport to the laboratory. • The field CoC document will be taped to the top inside cover of the shipping container in a sealed plastic envelope. • Shipment will be made as soon as practical or hand-delivered to the designated laboratory. The FTL will be responsible for ensuring the completion of the following forms: sample labels, CoC forms, custody seals for samples and coolers, shipping labels for coolers, and public courier air bills. Custody Procedures Documented sample custody is one of several factors that are necessary for the admissibility of environmental data as evidence in a court of law. Custody procedures help to satisfy the two major requirements for admissibility: relevance and authenticity. Sample custody is addressed in three parts: field sample collection, laboratory analysis, and final evidence files. A sample file is under custody when any one of the following conditions is satisfied: • The item is in the actual physical possession of an authorized person. • The item is in view of the person after being in his or her possession. • The item was placed in a secure area to prevent tampering. • The item is in a designated and identified secure area with access restricted to authorized personnel only. The FTL (or designee) is responsible for the care and custody of the samples collected until they are relinquished to the laboratory or entrusted to a commercial courier. Custody procedures apply to all environmental and associated field QC samples obtained as part of the data collection system.

HGL, UFP-QAPP, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 56 WORKSHEET #37 DATA USABILITY ASSESSMENT Summarize the usability assessment process and all procedures, including interim steps and any statistics, equations, and computer algorithms that will be used: Definitive data will be received as validated from EPA Region 4. HGL will assess the usability of the definitive data by evaluation of DQIs as described in Worksheet #12 and determining if the project-required QLs listed in Worksheet #15 were achieved for nondetected Site contaminants of concern. In addition, data usability will be assessed as follows: 1) If no detectable results were reported and data are acceptable from the verification and validation steps, then the data are usable; 2) If detectable concentrations are reported and the verification and validation steps are acceptable, the data are usable; and 3) If verification and validation are not acceptable, the data are qualified during data validation. The data that are estimated (J, UJ) for minor QC deviations generally do not affect the data usability. Data that are rejected for major QC deviations affect usability. The impact of rejected data will be assessed in the Data Evaluation Report, and re-sampling may be necessary. Describe the evaluative procedures used to assess overall measurement error associated with the project: The validation of definitive data will follow the requirements of EPA Region 4 data validation SOPs to assess conformance with the requirements of the methods, SOPs, and objectives stated in this UFP-QAPP. The findings of the data validation will generate qualifiers applied to the data considered in context to assess overall usability of the data. A Data Evaluation Report will be prepared after the field sampling event by HGL that will include the results of the usability assessment review performed by the project data management team. Identify the personnel responsible for performing the usability assessment: HGL PM, project chemist, and data manager. Describe the documentation that will be generated during usability assessment and how usability assessment results will be presented so that they identify trends, relationships (correlations), and anomalies: An overall assessment of the impact of data usability issues will be presented in the Data Evaluation Report.

(HGL) at the Holcomb Creosote Company (HCC) Site located in Yadkinville, Yadkin County, North Carolina. The overall Site location is shown on Figure 1.1. The Site facility plan is shown on Figure 1.2. These activities are being conducted by HGL for the U.S. Environmental Protection Agency (EPA) Region 4 under Design and Engineering Services (DES) Contract 68HE0318D0006, Task Order 68HE0422F0071. The purpose of this task order is to oversee the Remedial Action (RA) for soil and groundwater in accordance with the Record of Decision (EPA, 2018). Several planning documents have been prepared by HGL to describe and detail the sampling activities, data quality objectives for field and laboratory data, data management practices, and investigation-derived waste (IDW) handling procedures to be followed during field activities. Other planning documents include the following: • A Uniform Federal Policy (UFP)-Quality Assurance Project Plan (QAPP), which is the primary planning document, and includes the project organization, planned activities, and quality assurance/quality control (QC) procedures necessary to complete the field work. The UFP-QAPP will be implemented to ensure that the data collected are valid for the intended end use, and that data meet the requirements of the data quality objectives. The UFP-QAPP includes the following documents as appendices: o A FSP (this document) (Appendix A of the UFP-QAPP) that describes the sampling objectives and activities for completing the RA data collection efforts to address data gaps and support the RA. o A Data Management Plan (Appendix B of the UFP-QAPP) that provides procedures for managing field and laboratory data generated by the field investigations. • A Site Management Plan that addresses the coordination and control of Site activities during the field investigation. • A Site Health and Safety Plan that defines the preventative and protective procedures that will be implemented during the field activities to ensure the safety of the field team. This FSP (Appendix A of the UFP-QAPP) describes the sampling objectives and activities for completing the additional data collection activities needed to support the RA. This FSP includes guidance for all fieldwork by defining in detail the sampling and data-gathering methods to be used during sampling activities. The FSP also includes a Waste Management Plan (WMP) as Section 4.0 that describes the procedures for safe storage and disposal of wastes that will be generated during fieldwork. As an Appendix to the primary planning document, the UFP-QAPP, HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 1-2 the FSP includes only information needed by HGL’s field sampling teams to execute the fieldwork. Information presented elsewhere in the UFP-QAPP is incorporated into the FSP by reference to the appropriate UFP-QAPP worksheet(s). HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 2-1 2.0 SITE BACKGROUND See Worksheet #10 of the UFP-QAPP. HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 3-1 3.0 FIELD SAMPLING ACTIVITIES The sampling process was designed to ensure that the sampling objectives are fulfilled for the RA. The objective of the field investigation is to define the extent of naphthalene concentrations greater than 180 micrograms per kilogram (µg/kg) in unsaturated soils above the water table. To accomplish this objective, surface and subsurface soil samples will be collected using a direct-push technology drilling rig or hand auger. In addition, geotechnical data are needed to evaluate the QC of the soil RA solidification/stabilization (S/S) and in situ solidification/ stabilization (ISS). The sampling design presented in the following sections has been developed based on the results of previous Site investigations and input from the EPA. These subsections describe the sampling rationale and approach, and include number, types, and locations of samples to be collected and the methods of analyses to be performed. All field sampling activities will be performed in accordance with HGL’s standard operating procedures (SOPs) included in Appendix D of the UFP-QAPP and applicable EPA Region 4 Laboratory Services and Applied Science Division (LSASD) SOPs included in Appendix E of the UFP-QAPP. All SOPs to be used in field effort are listed in Worksheet #21 of the UFP-QAPP. Standardized forms to be used for recording field data and documentation are included in Attachment 1 of this FSP. In instances where HGL and EPA Region 4 SOPs differ, the EPA Region 4 procedures will be followed. 3.1 SOIL SAMPLING HGL will conduct soil sampling activities to define the extent of naphthalene greater than 180 µg/kg. A secondary objective of the soil sampling will be to reduce the size of the area requiring excavation and potentially establish cut lines for use during RA implementation to eliminate the need for post-excavation confirmation sampling. HGL has identified 17 proposed soil boring locations, shown in Figures 3.1a and 3.1b. To support the rationale for the boring locations (presented on Table 3.1), Figures 3.1a and 3.1b also depict the remedial investigation (RI) soil sampling locations and indicate the previous soil sampling locations where naphthalene exceeded 180 µg/kg. Additional soil boring locations may be added in the field in consultation with and approval from the EPA Remedial Project Manager if field observations such as odor, staining, elevated organic vapors, or non-aqueous phase liquid (NAPL) indicate that the proposed boring locations may not fully delineate the extent of contamination. Personnel will conduct field screening of the soil cores using a photoionization detector and also note any visual or olfactory observations (e.g., stained soil). All soil borings will be logged in accordance with HGL SOP 403.07 Borehole Logging. Soil samples will be collected from the following locations and depth intervals: • Near the unnamed tributary: Soil samples will be collected to delineate soil contamination east of HCSB102 and HCSB172. The samples will be collected from 0 to 0.5 feet (ft) below ground surface (bgs) at three locations just west of the unnamed tributary. HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 3-2 • Near Excavation Area 5: Soil samples will be collected to delineate soil contamination south of HCSB134. The samples will be collected from 0 to 0.5 ft bgs at two locations, southeast and southwest of HCSB134. • HCSB113: As part of the ISS plan, naphthalene-contaminated overburden soil above the water table will be excavated and placed in the Site containment cell. However, at ISS Area F, north of the surface impoundment, the elevated naphthalene concentrations detected at soil boring HCSB113 at 4 to 8 ft bgs are possibly the result of NAPL in the sample. Therefore, overburden soil above the water table at Area F will be re-sampled to determine whether a portion of it can be segregated as clean backfill. Soil samples will be collected at 2 to 4 ft bgs and 4 to 6 ft bgs at HCSB113. Four additional soil samples will also be collected at 2 to 4 ft bgs and 4 to 6 ft bgs from two step-out soil borings north and west of HCSB113. • HCSB141: One soil sample will be collected at 8 to 10 ft bgs to confirm the soil contamination at HCSB141, near US Highway 601. Additionally, cutline soil sampling will be conducted around HCSB141. Eight additional soil samples will also be collected at 8 to 10 ft bgs and 10 to 12 ft bgs from four step-out soil borings north, south, east, and west of HCSB141. • HCSB175: Cutline soil sampling will be conducted around HCSB175. Eight additional soil samples will also be collected at 2 to 5 ft bgs and 5 to 7 ft bgs from four step-out soil borings north, south, east, and west of HCSB175. The rationale for the boring locations is presented on Table 3.1. Soil sampling will be conducted in accordance with HGL SOP 02.13 Surface and Shallow Depth Soil Sampling and the EPA Region 4 SOP LSASDPROC-300-R4 Soil Sampling. For each depth interval, the soil from the interval will be composited, and a sample collected for analysis of polynuclear aromatic hydrocarbons (PAHs) with Selected Ion Monitoring (SIM), unless NAPL or gross contamination is encountered. Samples with NAPL or gross contamination will be analyzed for routine PAHs without SIM. The soil samples will be submitted to either a designated Contract Laboratory Program laboratory or the EPA Region 4 laboratory. After sampling is completed, each boring will be abandoned in accordance with the decommissioning procedure presented in EPA Region 4 LSASD SOP LSASDPROC-300-R4 Soil Sampling. Boreholes less than 10 ft deep that remain open and do not approach the water table may be decommissioned by pouring 30% solids bentonite grout from the surface or pouring bentonite pellets from the surface and hydrating the pellets in lifts. Boreholes deeper than 10 ft, or any borehole that intercepts groundwater, must be decommissioned by pressure grouting with 30% solids bentonite grout, either through a re-entry tool string or through a tremie pipe introduced to within several feet of the borehole bottom. The geographic coordinates of each soil boring will be measured and recorded using a handheld global positioning system (GPS) unit. GPS measurements will be collected in accordance with EPA Region 4 SOP LSASDPROC-110-R5 Global Positioning System. HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 3-3 3.2 GEOTECHNICAL QUALITY CONTROL TESTING QC samples for laboratory testing of unconfined compressive strength (UCS) will be performed on mixed and cured samples at a frequency of 2 samples per mixing zone (6 zones: Area A; Area B; Areas C & D; Area E; Areas F & G; and the stabilization pit), for a total of 12 samples for the total volume of soils to be treated with S/S of 1,678 bank cubic yards (bcy) (approximately 1 sample per every 140 bcy). For each sampling event, the RA Contractor will prepare the minimum number of replicate sample molds (coupons) for UCS of soil-cement testing by ASTM International (ASTM) D 1633 testing at 7, 14, and 28 days, and reserve samples for flexible wall permeability testing by ASTM D 5084 at 14 and 28 days. Information on sampling requirements is located in Specification 02 55 00 in the Final (100%) Soil Remedial Design (HGL, 2021). 3.3 FIELD QUALITY CONTROL SAMPLES Field QC samples will consist of field duplicates, equipment rinsate blanks, field blanks, and temperature blanks. Requirements for field QC samples are discussed in UFP-QAPP Worksheet #20. Table 3.2 provides a summary of the QC samples, analyses, preservatives, and containers necessary to complete the sampling activities. 3.4 SAMPLE HANDLING AND CUSTODY Sample handling and custody includes the field-related considerations connected with selecting sample containers, preservatives, allowable holding times, and analyses requested. Requirements for sample handling including sample labeling, tracking and management, field sample packaging and shipping, and custody procedures are discussed in UFP-QAPP Worksheets #26 and #27. Table 3.1 provides a summary of samples required along with the assigned station identifications (IDs) and sample IDs. Table 3.2 provides a summary of the parent samples, QC samples, analyses, preservatives, and containers necessary to complete the sampling activities. 3.5 DECONTAMINATION PROCEDURES Procedures for decontamination will be implemented to avoid cross contamination of samples that are submitted for chemical analyses. Decontamination procedures will meet the requirements contained in HGL SOP 411.02 Sampling Equipment Cleaning and Decontamination and EPA Region 4 Science and Ecosystem Support Division (SESD) SOP SESDPROC-205-R3 Field Equipment Cleaning and Decontamination. Final decontamination of all equipment used to collect the samples will be required prior to equipment demobilization from the Site. This decontamination step is required to prevent contaminants from being transported off Site. The same procedures used for decontamination between sample locations will be used during final decontamination. 3.5.1 Drilling Equipment Decontamination The following is the standard procedure for field cleaning augers, drill stems, rods, tools, and associated equipment. HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 3-4 1. Wash with tap water and soap, using a brush if necessary, to remove particulate matter and surface films. Steam cleaning (high-pressure hot water with soap) may be necessary to remove matter that is difficult to remove with the brush. Drilling equipment that is steam cleaned will be placed on racks or sawhorses at least 2 ft above the floor of the decontamination pad. Drill rods, etc., that are hollow or have holes that transmit water or drilling fluids will be cleaned on the inside with vigorous brushing. 2. Rinse thoroughly with tap water. 3. Remove from the decontamination pad and cover with clean, unused plastic. If stored overnight, the plastic will be secured to ensure that it stays in place. 3.5.2 Sampling Equipment Decontamination All non-disposable sampling and testing equipment, which is exposed to the sample medium, will be decontaminated to prevent cross contamination between sampling points. Equipment decontamination procedures will follow the HGL SOP 411.02 Sampling Equipment Cleaning and Decontamination and the EPA Region 4 SOP LSASDPROC-205-R4 Field Equipment Cleaning and Decontamination. 3.6 FIELD DOCUMENTATION REQUIREMENTS Specific records and data must be maintained for each field activity to ensure that samples and data are traceable and defensible. Requirements for field documentation are discussed in UFP- QAPP Worksheet #29. HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 4-1 4.0 WASTE MANAGEMENT PLAN The RA contractor is responsible for the final disposition of all waste generated from field investigation and RA activities. This WMP describes the procedures for safe storage and disposal of wastes that will be generated during HGL’s pre-RA field work at HCC. IDW is expected to consist of soil cuttings from soil sampling, decontamination water, and general refuse including discarded personal protective equipment and disposable sampling equipment. IDW will be characterized under the “contained-in” policy, which states that environmental media are considered to contain Resource Conservation and Recovery Act (RCRA) hazardous waste: (1) when media is contaminated with characteristic hazardous waste and exhibits a characteristic of hazardous waste; or (2) when the media is contaminated with hazardous constituents from RCRA-listed hazardous waste. Some IDW generated at HCC is expected to be contaminated with K001 and F034 listed waste. The “contained-in” policy states that environmental media contaminated with a hazardous waste must be managed as if they are hazardous wastes until they no longer contain the listed waste, no longer exhibit a characteristic, or are delisted. In order for environmental media contaminated with a listed waste to no longer be considered hazardous, the handler of the media must demonstrate to the EPA's or the authorized state's satisfaction that the media no longer poses a sufficient health threat to merit RCRA regulation. HGL prepared a "contained-in" determination (HGL, 2020) for environmental media at the Site contaminated with RCRA-listed K001 and F034 wastes for the purpose of characterizing remediation waste for off-Site disposal. The “contained-in” determination considered protection of human health and the environment for the expected management of the contaminated media under the Comprehensive Environmental Response, Compensation, and Liability Act and applicable State of North Carolina policy. The “contained-in” determination calculated conservative, health-based concentrations of the hazardous constituents of K001 and F034 wastes using a reasonable maximum exposure scenario to determine levels at which remediation wastes would be deemed to no longer contain K001 and/or F034 waste. The calculated concentrations along with the applicable State of North Carolina “contained-out” levels are included in Tables 1 and 2 of the "contained-in" determination (HGL, 2020). These tables are included in Attachment 2 of this FSP. The “contained-out” levels were selected as the lower of the risk-based concentrations protective of an outdoor worker receptor with a non-cancer hazard index of 1.0 and an excess cancer risk of 1x10-5 or the applicable North Carolina Department of Environmental Quality (NCDEQ) “contained-out” level. For soil, the Toxicity Characteristic Leaching Procedure (TCLP) should also be considered as required under 40 Code of Federal Regulations (CFR) §261.24. It should be noted for soil that under NCDEQ policy, the NCDEQ “contained-out” TCLP limits can be used instead of the “contained-out” total soil levels for constituents with established “contained-out” TCLP limits. The “contained-out” total soil levels must be achieved for constituents without “contained-out” TCLP limits, or if TCLP is not analyzed. The selected “contained-out” levels also comply with the RCRA Land Disposal Restriction treatment standards for hazardous wastes as required under 40 CFR §268.40 and 40 CFR §268.49. The levels shaded in Tables 1 and 2 of the "contained-in" determination should be used for classifying remediation wastes generated at the Site as hazardous or non-hazardous for off-Site disposal (HGL, 2020). HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 4-2 Any solid or liquid wastes generated will be evaluated as a potentially hazardous waste in accordance with RCRA rules. All IDW will be managed in accordance with the EPA Region 4 SOP LSASDPROC-202-R4 Management of IDW. The following bullets summarize IDW control and disposal practices: • The RA Contractor, HGL, and their subcontractors will be responsible for handling waste generated during this investigation. The RA Contractor and EPA will be responsible for hazardous waste characterization and disposal arrangements. • Contaminated safety equipment, sampling equipment, soils, and decontamination fluids generated during the field investigation will be containerized in labeled Department of Transportation-approved 55-gallon drums and stored at a designated storage area determined by the RA Contractor on the HCC property for characterization and disposal. • Personal protective equipment waste generated during work will be decontaminated, stored in plastic bags, and disposed of at the end of each workday in an industrial dumpster at a location to be determined by the HGL field representative. The following assumptions have been made in the preparation of the WMP: • RCRA, Toxic Substances Control Act, and other regulatory (federal, State of North Carolina, and local equivalent) storage requirements may apply to the storage and staging of wastes at the HCC property. • The presence of creosote constituents in IDW will indicate that the media potentially contains K001- or F034-listed wastes and triggers RCRA regulation under the “contained-in” policy. The calculated concentrations along with the applicable State of North Carolina “contained-out” levels are included in Tables 1 and 2 of the "contained-in" determination (HGL, 2020). • Soil IDW will be placed under the cap (if it has not been constructed yet). Soil IDW produced after the cap will be segregated by the expected level of contamination to the extent practicable based on field observations and historical analytical results, as applicable, and containerized in 55-gallon drums. • Manifests will be completed for disposing of all hazardous wastes off-Site, signed by the RA Contractor “On Behalf of EPA.” The field team leader or designee, on a daily basis, will document the generation of IDW during the field investigation to ensure that the IDW is properly containerized and stored. Information will be recorded in a bound field logbook and will include the information listed below. • Drum number • Type of environmental media containerized • Date first accumulated • Source of the IDW (soil boring or monitoring well numbers) • Volume of soil or purge/decontamination water HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 4-3 HGL will collect a sufficient number of liquid and solid waste samples for proper characterization of the IDW for off-Site transportation and disposal. The number and type (discrete versus composite) of samples collected to characterize the IDW will be based on the requirements of the disposal facility. Additionally, a determination will be made as to whether use of the TCLP is appropriate. The requirements of the waste disposal facility and any applicable federal, state, or local discharge permits or other requirements will be consulted for this purpose, along with the “Rule of 20.” HGL expects that TCLP analyses for organic constituents or constituents in K001 and F034 wastes will be required. The IDW sample analytical results will be compared to the requirements of the waste disposal facility and with reference to any applicable federal, state, or local requirements to determine the appropriate disposal method. The containers will then be appropriately relabeled with the IDW characterization as either nonhazardous or hazardous. If material is found to be hazardous, arrangements will be made within 30 days with the IDW disposal subcontractor to have it moved to an off-Site disposal facility. No hazardous waste will remain on the Site for over 90 days. All off-Site transportation activities will be performed in accordance with U.S. Department of Transportation and State of North Carolina regulations. A goal of this WMP is to minimize, to the extent practical, the volume of IDW generated and removed from the Site for disposal. To minimize the volume of IDW generated, the following general rules will be applied: • Do not contaminate materials unnecessarily. • Plan work ahead of time based on the work procedure to be utilized. • Decontaminate and reuse material and equipment when practical. • Take to the work location only the materials needed to perform the work activity. Additional materials can be brought to the worksite if necessary. Materials can be stored in large containers, but the smallest container reasonable should be used to transport a material to the work location where it is needed. • Maintain cleaning supplies outside of any potentially contaminated area to keep them clean and to minimize the generation of additional waste. • Perform mixing of detergents or decontamination solutions outside of potentially contaminated areas. • Use drop cloths or other absorbent material to contain small spills or leaks. • Avoid a “bellows” effect (that is, ensure that air is removed from bags or other containers carrying waste materials) when bagging contaminated materials. • Use containers to minimize the spread of contamination (for example, use a bucket to contain an oil leak from equipment). • Do not place contaminated materials with clean materials. • Employ volume reduction techniques when practicable. • Verify that waste containers are solidly packed to minimize the number of containers. HGL, Field Sampling Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 4-4 • Use containers that are large enough to meet the needs of a specific work task, but not larger than necessary. • Use nonhazardous decontamination substances whenever possible.

(HGL) at the Holcomb Creosote Company (HCC) Site located in Yadkinville, Yadkin County, North Carolina. These activities are being conducted by HGL for the U.S. Environmental Protection Agency (EPA) Region 4 under Design and Engineering Services (DES) Contract 68HE0318D0006, task order (TO) 68HE0422F0071. The purpose of this TO is to prepare the Remedial Action for soil and groundwater in accordance with the Record of Decision (EPA, 2018). Several planning documents have been prepared by HGL to provide details regarding sampling activities, data quality objectives for field and laboratory data, data management practices, and investigation-derived waste handling procedures to be followed during field activities. Other planning documents include the following: • A Uniform Federal Policy (UFP)-Quality Assurance Project Plan (QAPP). The UFP- QAPP is the primary planning document for the TO and covers the project’s organization, planned activities, and quality assurance/quality control procedures necessary to complete the work. The UFP-QAPP will be implemented to ensure that the data collected are valid for the intended end use and that data meet the requirements of the data quality objectives. The UFP-QAPP includes the following documents as appendices: o A Field Sampling Plan (FSP) (Appendix A of the UFP-QAPP). The FSP describes the sampling objectives and activities for completing the Remedial Action data collection. The FSP includes guidance for all field work by detailing the sampling and data-gathering methods to be used during sampling activities. The FSP also includes a Waste Management Plan that describes the procedures for safe storage and disposal of wastes that will be generated during fieldwork. o The Data Management Plan (DMP) (This document) (Appendix B of the UFP- QAPP). The DMP details procedures to be used for managing field and laboratory data generated by the field investigations. • A Site Management Plan that addresses the coordination and control of Site activities during the field investigation. • A Site Health and Safety Plan (HASP). The HASP defines the preventative and protective procedures that will be implemented during the field activities to ensure the safety of the field team. As an appendix to the primary planning document, the UFP-QAPP, the DMP does not repeat information already presented in the UFP-QAPP. Accordingly, the information presented HGL, Data Management Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 2 elsewhere in the UFP-QAPP is incorporated into the DMP by reference to the appropriate UFP- QAPP worksheet(s). 2.0 FIELD DATA Site conditions during sampling and the care with which samples are collected and handled in the field may factor into their representativeness. This, in turn, could affect the ability of decision makers to make accurate and timely decisions concerning the contamination status of the Site. As appropriate, logbooks will be assigned to, and maintained by, key field team personnel. The logbooks will be used to record daily conditions/activities such as weather conditions, dates/times of significant events, level of personal protection equipment used, drilling activities, actual sample collection locations, photographs taken, problems encountered, and corrective actions taken to overcome problems. Additionally, the names of Site visitors and the purposes of their visits will be recorded. Finally, all logbooks will be maintained in accordance with HGL standard operating procedure (SOP) 300.04 Field Logbook Use and Maintenance and EPA Region 4 Laboratory Services and Applied Science Division (LSASD) SOP SESDPROC-1002-R0 Logbooks. Field logbooks and sample documentation, including chain of custody (CoC) forms and field sampling forms, provide a record that should allow a technically qualified individual to reconstruct significant field activities without resorting to memory. The field team leader is responsible for the maintenance and security of all field records at the end of each workday during field activities. At the completion of field activities, the field team leader will forward all field records to the HGL project manager. Field logbooks and field forms will be scanned into a legible PDF and retained in both electronic and printed versions for inclusion into Site reports as appendices. In addition, all logbooks and forms will be kept in the project file until project closeout, where they will be returned to EPA for permanent storage (if requested). 3.0 LABORATORY DATA Data management for analytical data generated is dictated by which laboratories perform analyses. Data resulting from analyses performed by the EPA Region 4 laboratory and the resulting data results are managed by EPA internally using Region 4 Laboratory Information Management System (R4LIMS) and EPA Region 4’s Environmental Quality Information System (EQuIS) data management software. Contract Laboratory Program (CLP) laboratory data is transmitted electronically to the EPA Region 4 LSASD Quality Assurance Section for data validation, and subsequently, the data and qualifiers are uploaded into the R4LIMS and EQuIS. Laboratory data generated during the Post and Lumber soil and sediment sampling investigation is planned to be from either the EPA Region 4 or a CLP laboratory. 4.0 ELECTRONIC DATA DELIVERABLES All field data and CoC information will be managed electronically using Scribe, which is a software tool developed by the EPA to assist in the process of managing environmental data. Scribe will be used to capture sampling, observational, and monitoring field data; print labels for collected samples; generate CoC documentation; and electronically transmit CoC reports and sample collection information to the EPA Region 4 or CLP laboratory. At the completion of field activities, electronic data deliverables (EDDs) of field data will be prepared as part of the data HGL, Data Management Plan, Holcomb Creosote Company Site, Yadkinville, North Carolina U.S. EPA Region 4 3 tabulation and evaluation process and will be provided to EPA in EQuIS format for upload to the regional EQuIS database, in accordance with the EPA Region 4 Superfund and Emergency Management guidance document SEMDPROC-009-R0 Environmental Data Submission. The EDD files presented in Table 4.1 below are expected to be required for this investigation.

Full analytical reports are provided to HGL via email in PDF and .data files containing analytical EDD files from R4LIMS@epa.gov. HGL also has secure access to the Region 4 EQuIS database to query and retrieve data for import to Microsoft Excel for preparation of data summary tables or for use in geographic information system (GIS) software for generation of figures. As part of TO closeout activities, HGL will provide EPA with a comprehensive, electronic final archive of sampling and monitoring data and data deliverables, including GIS files. All GIS files will be in standard Environmental Systems Research Institute format and have spatial reference information that describes the projection, datum, and where applicable, the collection methods. 5.0 REFERENCES U.S. Environmental Protection Agency (EPA), 2018.

If errors are made in any of these documents, corrections will be made by crossing a single line through the error and entering the correct information. All corrections must be initialed and dated. If possible, all corrections should be made by the individual making the error. Following are definitions of terms used in this section: Field Investigator Any individual who performs or conducts field sampling, observation and/or measurement activities in support of field investigations Project Leader The individual with overall responsibility for conducting a specific field investigation in accordance with this procedure Field Sample Custodian Individual responsible for identifying the sample containers and maintaining custody of the samples and the Chain-of-Custody Record Sample Team Leader An individual designated by the project leader to be present during and responsible for all activities related to the collection of samples by a specific sampling team Sampler The individual responsible for the actual collection of a sample Transferee Any individual who receives custody of samples subsequent to release by the field sample custodian Laboratory Sample Custodian Individual responsible for accepting custody of samples from the field sample custodian or a transferee One individual may fulfill more than one of the roles described above. COPY __________________________________________________________________________________ SESD Operating Procedure Page 6 of 15 SESDPROC-005-R3 Sample and Evidence Management Sample and Evidence Management(005)_AF.R3 Effective Date: May 25, 2016 2.2 Sample and Evidence Identification Procedures 2.2.1 Sample Identification The method of sample identification used depends on the type of sample collected. Field measurement samples are those collected for specific field analysis or measurement where the data are recorded directly in bound field logbooks or on the Chain-of-Custody Record. Examples of field measurements and analyses include XRF, pH, temperature, dissolved oxygen and conductivity. Samples collected for laboratory analysis will be identified by using a stick-on label or a tag which is attached to the sample container. In some cases such as biological samples, the label or tag may have to be affixed to a bag containing the sample. If a sample tag is used, the sample should be placed in a bag, then the sample and the tag will be placed in a second bag. The following information will be included on the sample label or tag using waterproof, non-erasable ink: • Project number; • Field identification or sample station number; • Date and time of sample collection; • Designation of the sample as a grab or composite; • Whether the sample is preserved or unpreserved; • The general types of analyses to be performed. Other information such as readily detectable or identifiable odor, color, or known toxic properties may be added as deemed necessary by the project leader or sample custodian. COPY __________________________________________________________________________________ SESD Operating Procedure Page 7 of 15 SESDPROC-005-R3 Sample and Evidence Management Sample and Evidence Management(005)_AF.R3 Effective Date: May 25, 2016 2.2.2 Digital Images – Photographs and Videos When digital images, which include but are not limited to photographs, digital still images and videos, are taken for purposes of documenting and supporting a field investigation, a record, containing relevant information, will be kept in a field logbook. The following information will be recorded in the log: • Digital Image Location or Station Identification • Description of what the digital image shows • Date and time the digital image was taken • Name of the individual that took the digital image • Digital file name (assigned by camera) • Orientation, if applicable • Other pertinent information When digital images are obtained during a field investigation, the permanent record for the official project file, will be stored on a project dedicated data storage device, which includes but is not limited to Secure Digital (SD) card, Compact Discs (CD), or Flash Drives. A new data storage device will be utilized for each project and once the project is completed the device, containing the unaltered investigation-related images, will be labeled with the project’s unique identification number and placed in the official file. Photographs taken for educational or other purposes should be stored on an additional storage device and should not be included in the official project file. It is SESD’s policy that, during a field investigation, official project specific digital images should be obtained using SESD issued electronics but in the event that the only option field personnel have is to utilize their own electronic equipment the following steps should be taken: • Record all required digital image information, as described above • Record devices make, model and owner’s name • Transfer all digital images to a project specific data storage device and adhere to requirements outlined in the EPA Records Management Policy (CIO 2155.3). COPY __________________________________________________________________________________ SESD Operating Procedure Page 8 of 15 SESDPROC-005-R3 Sample and Evidence Management Sample and Evidence Management(005)_AF.R3 Effective Date: May 25, 2016 2.2.3 Identification of Physical Evidence Physical evidence, other than samples, will be identified, when possible, by recording the necessary information on the evidence. When samples are collected from vessels or containers which can be moved (drums for example), the vessel or container should be marked with the field identification or sample station number for future identification. The vessel or container may be labeled with an indelible marker (e.g., paint stick or spray paint). The vessel or container need not be marked if it already has a unique marking; however, these markings will be recorded in the bound field logbooks. In addition, it is suggested that photographs of any physical evidence (markings, etc.) be taken and the necessary information recorded in the field logbook. Occasionally, it is necessary to obtain copies of recorder and/or instrument charts from facility owned analytical equipment, flow recorders, etc., during field investigations and inspections. A unique identifier will be recorded on the document with that information as well as the following recorded in the logbook: • Starting and ending time(s) and date(s) for the chart; • An instantaneous measurement of the media being measured by the recorder will be taken and entered at the appropriate location on the chart along with the date and time of the measurement; and • A description of the location being monitored and other information required to interpret the data such as type of flow device, chart units, factors, etc. The field investigator will indicate who the chart (or copy of the chart) was received from and enter the date and time, as well as the field investigator's initials. Documents such as technical reports, laboratory reports, etc., should be marked with the field investigator's signature, the date, the number of pages and from whom they were received. Documents that are claimed by a facility to be “confidential” and, therefore, potentially subject to the Confidential Business Information requirements, will be handled in accordance with SESD Operating Procedure for Control of Records (SESDPROC-002).

To document chain-of-custody, an accurate record must be maintained to trace the possession of each sample, or other evidence, from the moment of collection to its introduction into evidence. 3.2 Sample Custody A sample or other physical evidence is in custody if: • It is in the actual possession of an investigator; • It is in the view of an investigator, after being in their physical possession; • It was in the physical possession of an investigator and then they secured it to prevent tampering; and/or • It is placed in a designated secure area. 3.3 Documentation of Chain-of-Custody The following are used to identify and demonstrate how sample integrity is maintained and custody is ensured. Sample Identification A stick-on sample label or a tag should be completed for each sample container using waterproof, non-erasable ink as specified in Section 2.2.1. Sample Seals If appropriate, samples should be sealed as soon as possible following collection using a custody seal with EPA identification. The sample custodian or project leader will write the date and their initials on the seal. The use of custody seals may be waived if field investigators keep the samples in their custody as defined in Section 3.2, from the time of collection until the samples are delivered to the laboratory analyzing the samples. Field Sample Custodian The field sample custodian is the person designated by the project leader to receive and manage custody of samples while in the field, including labeling and custody sealing. COPY __________________________________________________________________________________ SESD Operating Procedure Page 10 of 15 SESDPROC-005-R3 Sample and Evidence Management Sample and Evidence Management(005)_AF.R3 Effective Date: May 25, 2016 Chain-of-Custody Record The field Chain-Of-Custody record is used to document the custody of all samples or other physical evidence collected and maintained by investigators. All physical evidence or samples will be accompanied by a Chain-Of-Custody Record. This form may be generated by sample custody management software (Section 5) or it may be a pre-printed multi-sheet carbonless form for hand entry of required information. The Chain-Of-Custody Record documents transfer of custody of samples from the sample custodian to another person, to the laboratory or other organizational elements. The Chain-of-Custody Record will not be used to document the collection of split samples where there is a legal requirement to provide a receipt for samples (see Section 4, Receipt for Samples Form (CERCLA/RCRA/TSCA)). The Chain-Of-Custody Record also serves as a sample logging mechanism for the laboratory sample custodian. A separate Chain-of-Custody Record should be used for each final destination or laboratory used during the investigation. All information necessary to fully and completely document the sample collection and required analyses must be recorded in the appropriate spaces to complete the field Chain-Of-Custody Record. The following requirements apply to Chain-Of-Custody records generated by either sample custody management software or by hand entry on pre-printed forms: • All sampling team leaders must sign in the designated signature block. • One sample should be entered on each line and not be split among multiple lines. • If multiple sampling teams are collecting samples, the sampling team leader's name should be clearly indicated for each sample. • The total number of sample containers for each sample must be listed in the appropriate column. Required analyses should be entered in the appropriate location on the Chain-of-Custody Record. • The field sample custodian, project leader or other designee, and subsequent transferee(s) should document the transfer of the samples listed on the Chain-of-Custody Record. Both the person relinquishing the samples and the person receiving them must sign the form. The date and time that this occurs should be documented in the proper space on the Chain-of-Custody Record. The exception to this requirement would be when packaged samples are shipped with a common carrier. Even though the common carrier accepts the samples for shipment, they do not sign the Chain-of- Custody Record as having received the samples. COPY __________________________________________________________________________________ SESD Operating Procedure Page 11 of 15 SESDPROC-005-R3 Sample and Evidence Management Sample and Evidence Management(005)_AF.R3 Effective Date: May 25, 2016 • The last person receiving the samples or evidence will be the laboratory sample custodian or their designee(s). The Chain-of-Custody Record is a uniquely identified document. Once the Record is completed, it becomes an accountable document and must be maintained in the project file. The suitability of any other form for chain-of-custody should be evaluated based upon its inclusion of all of the above information in a legible format. If chain-of-custody is required for documents received during investigations, the documents should be placed in large envelopes, and the contents should be noted on the envelope. The envelope will be sealed and an EPA custody seal placed on the envelope such that it cannot be opened without breaking the seal. A Chain-Of-Custody Record will be maintained for the envelope. Any time the EPA seal is broken, that fact will be noted on the Chain-Of-Custody Record and a new seal affixed, as previously described in this section. Physical evidence such as video tapes or other small items will be placed in an evidence bag or envelope and an EPA custody seal should be affixed so that they cannot be opened without breaking the seal. A Chain-Of-Custody Record will be maintained for these items. Any time the EPA seal is broken, that fact will be noted on the Chain-of-Custody Record and a new seal affixed. EPA custody seals can be used to maintain custody of other items when necessary by using similar procedures as those previously outlined in this section. Samples should not be accepted from other sources unless the sample collection procedures used are known to be acceptable, can be documented and the sample chain-of-custody can be established. If such samples are accepted, a standard sample label containing all relevant information and the Chain-Of-Custody Record will be completed for each set of samples. 3.4 Transfer of Custody with Shipment Transfer of custody is accomplished by the following: • Samples will be properly packaged for shipment in accordance with the procedures outlined in SESD Operating Procedure for Packing, Marking, Labeling and Shipping of Environmental and Waste Samples (SESDPROC-209). • All samples will be accompanied by the laboratory copy of the Chain-Of-Custody Record. If pre-printed forms are used, the white and pink sheets will be sent. If sample custody management software is used to generate the Chain-Of-Custody Record, the laboratory copy is identified with an “L” in the upper right corner. If multiple coolers are needed for shipment to a particular laboratory, the laboratory COPY __________________________________________________________________________________ SESD Operating Procedure Page 12 of 15 SESDPROC-005-R3 Sample and Evidence Management Sample and Evidence Management(005)_AF.R3 Effective Date: May 25, 2016 copy of the Chain-Of-Custody Record for the entire shipment is placed in a sealed plastic bag in one of the coolers. When shipping samples via common carrier, the "Relinquished By" box should be filled in; however, the "Received By" box should be left blank. The laboratory sample custodian is responsible for receiving custody of the samples and will fill in the "Received By" section of the Chain-of-Custody Record. One copy of the Record will be provided to and retained by the project leader. After samples have been received and accepted by the laboratory, a copy of the Chain-of-Custody Record, with ASB sample identification numbers, will be transmitted to the project leader. This copy will become a part of the project file. • If sent by mail, the package will be registered with return receipt requested. If sent by common carrier, an Air Bill should be used. The Air Bill number, shipment tracking number or registered mail serial number will be recorded in the remarks section of the Chain-Of-Custody Record.

The Toxic Substances Control Act (TSCA) contains similar provisions. The laws do not require that homeowners or other off-site property owners be given this form. 4.2 Receipt for Samples Form If necessary, a Receipt for Samples form, using either the pre-printed form or one generated by sample custody management software, is to be used to satisfy the receipt for samples provisions of RCRA, CERCLA and TSCA. The form also documents that split samples were offered and either "Received" or "Declined" by the owner/operator of the facility or site being investigated (if a sample is split with a facility, state regulatory agency or other party representative, the recipient should be provided (if enough sample is available) with an equal weight or volume of sample). All information must be supplied in the indicated spaces to complete the Receipt for Samples form. • The sampler(s) must sign the form in the indicated location • Each sample collected from the facility or site must be documented in the sample record portion of the form. The sample station number, date and time of sample collection, composite or grab sample designation, whether or not split samples were collected (yes or no should be entered under the split sample column), a brief description of each sampling location and the total number of sample containers for each sample must be entered. • The bottom of the form is used to document the site operator's acceptance or rejection of split samples. The project leader must sign and complete the information in the "Split Samples Transferred By" section (date and time must be entered). If split samples were not collected, the project leader should initial and place a single line through "Split Samples Transferred By" in this section. The operator of the site must indicate whether split samples were received or declined and sign the form. The operator must give their title, telephone number and the date and time they signed the form. If the operator refuses to sign the form, the sampler(s) should note this fact in the operator's signature block and initial this entry.

When possible, the sample custody management software should be used during all field investigations. Once the appropriate information is entered into the computer, the software will generate stick-on labels for the sample containers and will generate sample receipt forms and chain-of-custody records for the appropriate laboratory. The advantages to this system include faster processing of samples and increased accuracy. Accuracy is increased because the information is entered only once, and consequently, consistent for the bottle labels, sample receipt forms and chain-of-custody records. .

Observations, data and calculations will be recorded at the time they are made. 2. Dedicated bound logbooks will be used. 3. Entries will be legible, containing pertinent, accurate, and inclusive documentation of project activities, free of personal feelings or other terminology which might prove inappropriate. 4. Unless prohibited by environmental conditions, pens with permanent ink will be used to record all data. When environmental conditions do not make it feasible to use permanent ink, entries should be made using a non-smear lead pencil (e.g., 2H or 3H). Upon returning from the field, the project leader will photocopy the penciled section of the logbook and certify, in writing, that the photocopied record is a true copy of the original logbook entry. The photocopy will be included in the project file. 5. Entries in logbooks shall be dated and signed or initialed by staff. 6. Data or other information that has been entered incorrectly shall only be corrected using a single strike-through, date and initials of the person making the correction. Under no circumstances should the incorrect material be erased, made illegible or obscured so that it cannot be read. 7. To demonstrate continuity of the work and maintain the integrity of the data collection process, pages should not be removed from any bound logbook. 8. Blank pages or spaces should not be present in logbooks. Blank areas should be lined through and initialed and dated to prevent the opportunity for back-filling. 9. Logbook pages and books shall be numbered. The numbering format will consist of “page x of y”, where “x” is the current page number and “y” is the total number of pages of the logbook. 10. To facilitate accurate and complete documentation of activities, SESD-generated forms may be used. In order to be utilized, SESD-generated forms must be bound prior to use and adhere to all requirements outlined in this procedure. In cases where unbound pages/forms are necessary due to project requirements or practicality, the appropriate Section Chief and System Manager will determine the best course of action. 11. If pre-printed adhesive labels are used in logbooks or bound forms to facilitate organization of information entry, the SESD staff responsible for taking notes will sign the label with the signature beginning on the label and ending on the page of the logbook such that the label cannot be removed without detection. Uncontrolled When Printed Logbooks SESDPROC-1002-R0 Effective Date: October 1, 2017 Page 4 of 10 1.2 Laboratory Logbooks The following are requirements for laboratory logbooks, in addition to those established in Section 1.1. Each sample preparation, analysis or equipment check is maintained using logbooks in the appropriate laboratory. Active logbooks are maintained within the laboratory where the instrument or equipment is located and should be maintained with the instrument throughout its useful life. At such time the instrument is removed from service, the logbook is transferred with the appropriate form to the LQM, and then to the SESD Records Room. 1.2.1 Instrument Maintenance Logbooks Each major instrument shall have a maintenance logbook. At a minimum the following information will be included: 1. Instrument serial number 2. Instrument’s unique name 3. Software version 4. In-service date (if known) In addition, maintenance, service and repair records are maintained in these logbooks. Preventive maintenance schedules should be noted in the log, or in a separate maintenance log. When a service or maintenance call is completed by the vendor, the analyst should place a copy of the documentation or transcribe the details for the work that was performed on the instrument in the logbook. The original work order invoice should be provided to the Office of Program Support for payment. Instrument Maintenance logbooks are purchased as bound record books that contain pre-numbered pages. The numbering convention does not account for the number of pages per book. 1.2.2 Instrument Logbooks Instrument logs shall include: 1. Instrument serial number 2. Date of analysis 3. Analyst and samples which have been analyzed 4. A reference or a record of which options or analytical conditions were used for analysis 5. Where appropriate, instrument acceptance criteria (e.g., tune criteria, sensitivity checks) 1.2.3 Preparation Logbooks Uncontrolled When Printed Logbooks SESDPROC-1002-R0 Effective Date: October 1, 2017 Page 5 of 10 Preparation logs shall document all information to reconstruct the preparation of samples, reagents, and standards, and should include, but not limited to: 1.

This is accomplished by printing a copy of the electronic record and including it in a notebook. These sequential logs must also include failed runs, or sequences which were abandoned prior to completion. When a pre- determined number of pages has been accumulated (e.g., 50 pages), the individual records are combined into a single bound logbook and retained as specified in the SESD Operating Procedure for Records Management (SESDPROC-1001). Any electronic records must accurately reflect actual analytical information. For analyses with holding times < 72 hours, or when time-critical or method-specified times are included in the analysis, the time of analysis must also be recorded. 1.2.5 Laboratory Equipment Logbooks Equipment Logbooks, such as balance logs, are maintained in the lab in close proximity to the equipment.

The official copy of this procedure resides on the LSASD Local Area Network (LAN). The Document Control Coordinator (DCC) is responsible for ensuring the most recent version of the procedure is placed on the LAN and for maintaining records of review conducted prior to its issuance. 1.2 General Precautions 1.2.1 Safety Proper safety precautions must be observed when managing IDW. Refer to the LSASD Safety, Health and Environmental Management Program (SHEMP) Procedures and Policy Manual and any pertinent site-specific Health and Safety Plans (HASP) for guidelines on safety precautions. These guidelines, however, should only be used to complement the judgment of an experienced professional. Address chemicals that pose specific toxicity or safety concerns and follow any other relevant requirements, as appropriate. 1.2.2 Procedural Precautions The following precautions should be considered when managing IDW: • Due to time limitations and restrictions posed by RCRA regulations on storage of hazardous waste, accumulation start dates should be identified on all drums, buckets or other containers used to hold IDW so that it can be managed in a timely manner. • During generation of both non-hazardous and hazardous IDW, keep hazardous IDW segregated from non-hazardous IDW to minimize the volume of hazardous IDW that must be properly managed. 2 Types of Investigation Derived Waste Materials which may become IDW include, but are not limited to: • Personal protective equipment (PPE) - This includes disposable coveralls, gloves, booties, respirator canisters, splash suits, etc. LSASDPROC-202-R4 Management of Investigated Derived Waste Effective Date: May 8, 2020 ______________________________________________________________________________________ Page 4 of 8 • Disposable equipment and items - This includes plastic ground and equipment covers, aluminum foil, conduit pipe, composite liquid waste samplers (COLIWASAs), Teflon® tubing, broken or unused sample containers, sample container boxes, tape, etc. • Soil cuttings from drilling or hand augering. • Drilling mud or water used for mud or water rotary drilling. • Groundwater obtained through well development or well purging. • Cleaning fluids such as spent solvents and wash water. • Packing and shipping materials. Table 1, found at the end of this procedure, lists the types of IDW commonly generated during field investigations and the current disposal practices for these materials. For the purpose of determining the ultimate disposition of IDW, it is typically distinguished as being either hazardous or non-hazardous. This determination is based on either clear regulatory guidance or by subsequent analysis. This determination and subsequent management is the responsibility of the program site manager. 3 Management of Non-Hazardous IDW Disposal of non-hazardous IDW should be addressed in the Sampling and Analysis Plan (SAP) or QAPP for the investigation. To reduce the volume of any IDW transported back to the Field Equipment Center (FEC), it may be necessary to compact the waste into a reusable container, such as a 55-gallon drum. If the waste is from an active facility, permission should be sought from the operator of the facility to place the non-hazardous PPE, disposable equipment, and/or paper/cardboard into the facility’s dumpsters. If necessary, these materials may be placed into municipal dumpsters, with the permission of the owner. These materials may also be taken to a nearby permitted landfill. On larger studies, waste hauling services may be obtained and a dumpster located at the study site. Disposal of non-hazardous IDW such as drill cuttings, drilling mud, purge or development water, decontamination wash water, etc., should be specified in the approved SAP or QAPP. It is recommended that these materials be placed into a unit with an environmental permit, such as a landfill or sanitary sewer. These materials must not be placed into dumpsters. If the facility at which the study is being conducted is active, permission should be sought to place these types of IDW into the facility’s treatment system. It may be feasible to spread drill cuttings around the borehole, or, if the well is temporary, to place LSASDPROC-202-R4 Management of Investigated Derived Waste Effective Date: May 8, 2020 ______________________________________________________________________________________ Page 5 of 8 the cuttings back into the borehole. Non-hazardous monitoring well purge or development water may also be poured onto the ground down gradient of the monitoring well when site conditions permit. Purge water from private potable wells which are in service may be discharged directly onto the ground surface. The minimum requirements for this subsection are: • Non-hazardous liquid and soil/sediment IDW may be placed on the ground or returned to the source if doing so does not endanger human health or the environment or violate federal or state regulations. Under no circumstances, however, should monitoring well purge water be placed back into the well from which it came. • Soap and water decontamination fluids and rinses of such cannot be placed in any water bodies and must be collected and returned to the FEC for disposition. • The collection, handling and proposed disposal method must be specified in the approved SAP or QAPP. 4 Management of Hazardous IDW Disposal of hazardous or suspected hazardous IDW must be specified in the approved SAP or QAPP for the study or investigation. Hazardous IDW must be disposed as specified in USEPA regulations. If appropriate, these wastes may be placed back in an active facility waste treatment system. These wastes may also be disposed in the source area from which they originated if doing so does not endanger human health or the environment. If on-site disposal is not feasible, and if the wastes are suspected to be hazardous, appropriate tests must be conducted to make that determination. If they are determined to be hazardous wastes, they must be properly contained and labeled. They may be stored on the site for a maximum of 90 days before they must be manifested and shipped to a permitted treatment or disposal facility. Generation of hazardous IDW must be anticipated, if possible, to allow arrangements for proper containerization, labeling, transportation and disposal/treatment in accordance with USEPA regulations. The generation of hazardous IDW should be minimized to conserve Division resources. Most routine studies should not produce any hazardous IDW, with the possible exception of spent solvents and, possibly, purged groundwater. The use of solvents during field cleaning of equipment should be minimized by using solvent-free cleaning procedures for routine cleaning and decontamination (see SESD Operating Procedure for Field Equipment Cleaning and Decontamination, SESDPROC-205). If solvents are needed, the volume should be minimized by using only the amount necessary and by capturing the residual solvent separately from the aqueous decontamination fluids (detergent/wash water mixes and water rinses). At a minimum, the requirements of the management of hazardous IDW are as follows: LSASDPROC-202-R4 Management of Investigated Derived Waste Effective Date: May 8, 2020 ______________________________________________________________________________________ Page 6 of 8 • Spent solvents must be left on-site with the permission of site operator and proper disposal arranged. • All hazardous IDW must be containerized. Proper handling and disposal should be arranged prior to commencement of field activities. 5 References LSASD Operating Procedure for Field Equipment Cleaning and Decontamination, LSASDPROC-205, Most Recent Version United States Environmental Protection Agency (US EPA). 2001.

Information 1.1 Purpose This document describes the methods to be used in submitting environmental data electronically to the United States Environmental Protection Agency (the EPA) Region 4 Superfund and Emergency Management Division (SEMD) personnel and their contractors as well as other EPA personnel working on the EPA Region 4 Superfund Program sites and/or projects. These methods occur during field activities that result in creating, handling, and managing field documentation and resulting in the creation of environmental data to be submitted to the EPA Region 4 data management system. The goal of this SOP for environmental data submission is to guide the EPA Region 4 SEMD personnel and contractors to submit the appropriate required electronic data. 1.2 Scope/Application The methods described in this document are to be used by all data providers when preparing and submitting environmental data electronically to the EPA Region 4, regardless of the originating program. The enforcement of such methods is supported by the SEMD Director’s Memo “Region 4 Data Management and Electronic Data Deliverables” that may be found at: http://www2.epa.gov/sites/production/files/2015-09/documents/ddeddmemo.pdf This document does not cover the use of DART, EQuIS™ Professional, or creating maps and reports. Extensive documentation on the use of EQuIS Professional and EQuIS Enterprise can be found at: https://help.earthsoft.com. 1.3 Documentation/Verification This procedure was prepared by persons deemed technically competent by the EPA Region 4 SEMD personnel, based on their knowledge, skills and abilities, and has been tested in practice and reviewed in print by a subject matter expert. The official copy of this procedure will be scanned into the EPA’s Superfund Enterprise Management System (SEMS) and published on EPA’s internet. The Document Control Coordinator (DCC) is responsible for ensuring the most recent version of the procedure is placed in SEMS and for maintaining records of review conducted prior to its issuance. 1.4 Acronyms CAD – Computer-Aided Drafting CLP – Contract Laboratory Program DART – Data Archival and ReTrieval DCC – Document Control Coordinator EDD – Electronic Data Deliverable EDGE – EQuIS Data Gathering Engine EPA Region 4 SEMD Page 6 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 EDP – EQuIS Data Processor EQuIS™ – Environmental Quality Information System EPA – United States Environmental Protection Agency GIS – Geographic Information System GNIS – Geographic Names Information System GPS – Global Positioning System LIMS – Laboratory Information Management System LSASD – Laboratory Services and Applied Science Division OSC – EPA’s On Scene Coordinator NPL – National Priorities List PRP – Potentially Responsible Party QAPP – Quality Assurance Project Plan R4DART – United States Environmental Protection Agency, Region 4 DART R4LIMS – United States Environmental Protection Agency, Region 4 LIMS RCRA – Resource Conservation and Recovery Act RPM – Remedial Project Manager SEMD – Superfund and Emergency Management Division SEMS – Superfund Enterprise Management System SMO – Sample Management Office URL – Uniform Resource Locator USGS – United States Geological Survey XML – Extended Markup Language 1.5 Definitions Activity Code (task_type) – Descriptive code for the EPA activity (RA - Remedial Action, RI – Remedial Investigation, etc.) for which the event is required.

Project – A project is defined as the data generated for a report. Project ID (task_code) – Unique ID associated with a project QAPP or for R4LIMS projects, it is associated with a single sampling event. For R4LIMS, this value is assigned by the Project Tracking System for the dataset being submitted. For all other project types, the R4DART will provide this Project ID. Project Number (task_code2) – A Project ID may have multiple Project Numbers or be the same as the Project ID. For R4LIMS, this value is assigned by the Project Tracking System for the Chain of Custody being submitted. For all other project types, R4DART will provide this Project Number. Project Tracking System – The EPA Region 4 LSASD’s project tracking system used for R4LIMS projects. Quality Assurance Project Plan – The controlling document for proposed field work. There may be multiple Project ID numbers assigned to the QAPP and will be used in EDDs generated for that project to uniquely identify the data to that event. Reference Value File – The reference value file (RVF) is associated with the EDP format file and is denoted with an .rvf file extension. This file contains the valid values reference tables that EDP uses to populate the drop-down menus that control when a specific type of value is required in an EDD. Example reference values are “mg/kg” (milligrams per kilogram) for a unit code or “GW” (groundwater) for a media code. These fields limit the type of data permitted in certain columns of the EDD, and the most recent valid values are in the RVF file. Therefore, it is extremely important to ensure you are using the most current file. Check the EarthSoft website to see if your version is current before working on your data. The link for this web site is provided below within section 2.3.2. EPA Region 4 SEMD Page 9 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 Scribe – Scribe is a software tool developed by EPA to assist in the process of managing environmental data.

The EPA Region 4 EDD Format File Guide provides detailed information for the creation of the EDD files that are required to be submitted. EPA Region 4 EQuIS Data Processor Reference Manual. The EPA Region 4 EQuIS Data Processor Reference Manual provides the information needed to download, install and maintain the EDP software, as well as how to use the software to proof EDDs and create data packages. EPA Region 4 Geographic Information System Deliverable Guidance. The EPA Region 4 GIS Deliverable Guidance document provides specific requirements and file delivery formats for all GIS materials developed in support of the program. EPA Region 4 SEMD Page 10 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 2 Introduction 2.1 Data Sources Data is submitted electronically to the EPA Region 4 from multiple sources. It should be emphasized that the differences between the processes for data submittal arise solely from the inherent efficiencies afforded to EPA lead investigations because the work may be done ‘in-house’. There is no difference in the types of data submitted, or the format of the files being submitted. Regardless of how EDD files are created (or what organization led the investigation), the files must meet the specifications of the EPA Region 4 EDD Format File Guide. All GIS materials developed in support of the program must meet the specific requirements and file delivery formats specified in the EPA Region 4 Geographic Information System Deliverable Guidance. 2.2 Overview The following summary provides a general outline of the process for submitting environmental data to the EPA Region 4. Create the Site or Waterbody – If the site or waterbody does not exist in DART, it must be created. Creating the site or waterbody is the responsibility of the R4DART coordinator. Create the Project – For R4LIMS projects, before data can be accepted by LSASD, a receiving project must be created in the R4LIMS System. Creating the project is the responsibility of the EPA Region 4 Sample Coordinator or EPA LSASD project lead. Data Submittal Summary – For non R4LIMS, a projects summary of the data must be submitted to provide a check that all data is received. The data provider is responsible for this task. DART Reports – For R4LIMS projects, reports are sent out automatically after the chain-of- custody information is uploaded to the Project Tracking System. The data provider (or EPA LSASD project leader) is responsible for responding to these reports. Create EDD(s) – Create EDDs to match the Data Submittal Summary. The data provider (or the EPA LSASD project leader) is responsible for this task. Check EDD(s) with EDP – All EDDs must be checked with EDP prior to submittal to the R4DART coordinator. The data provider (or EPA LSASD project leader) is responsible for this task. Submit EDD(s) – Submit all EDDs to EPAR4@EQuISonline.com. Attach the EDD(s) to the requesting email. The data provider (or EPA LSASD project leader) is responsible for this task. Proof and Correct as Needed – Notify R4DART of any needed corrections or additions arising from the EDDs being rejected. It is the EPA Region 4’s responsibility to update or add any information needed and inform back to the data provider completion or denial of request with EPA Region 4 SEMD Page 11 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 alternate action. It is then the responsibility of the data provider (or the EPA LSASD project leader) to proof the data for accuracy and resubmit with any needed corrections. The system is designed for data to be submitted once (i.e., sample coordinates and screening intervals for a monitoring well are submitted one time). The details for successfully completing the above steps can be found in Section 3 for EPA fund lead data submittals and Section 4 for Potentially Responsible Party (PRP) lead data submittals. GIS Data Submittal – GIS data deliverables must accompany the submission of a final report to the EPA Region 4 (see Section 5 for instructions). 2.3 EDP Standalone If you are a data provider to the EPA Region 4 and do not have access to an EPA workstation, you will need to download and install the EQuIS Data Processor (EDP) Standalone software. There is no charge to the user for this software. If you have access to an EPA workstation and need EDP installed, email R4DART@epa.gov. 2.3.1 Obtaining EDP Standalone Instructions for obtaining, installing, registering, and maintaining EDP Standalone can be found in the EPA Region 4 EQuIS Data Processor Reference Manual. 2.3.2 Using EDP Standalone EDP Standalone can be used to create smaller EDD files, but its primary function is to check EDDs for errors and create data packages for submittal. The structure of the EPA Region 4 EDD files is determined by the format file. If the format of any of the EDDs must be changed (rarely), then it will be necessary for users of the standalone version of EDP to obtain the updated format file. Instructions for downloading and installing updated format files can be found in the EPA Region 4 EQuIS Data Processor Reference Manual. Likewise, if the valid values used by EPA Region 4 are updated, it will then be necessary for users of the EDP Standalone to obtain the updated reference value file (.rvf). The current version of the EPA Region 4 .rvf file is at: https://www.epa.gov/superfund/region-4-superfund-electronic-data-submission. This file is updated periodically when the valid values are updated. The EPA Region 4 will notify all data providers, currently in the database, when it is necessary to update these files, but it is the responsibility of the data provider to ensure that the most current version is being used. EPA Region 4 SEMD Page 12 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 2.3.3 Valid Values in EDP The EPA Region 4 valid values can be viewed in EDP by starting EDP, then clicking on the “Reference Values” tab in the lower left corner. If you need a valid value that is not in the list (rare analyte, new analytical method, etc.), you may request it be added as outlined in the EPA Region 4 EDD Format File Guide. 2.3.4 Data Package A data package is created by EDP when the ‘sign and submit’ function is used to save the EDD. This creates an archive file (.zip) containing all EDDs that were loaded into EDP. The data package must be properly named, including .dat file extension. 2.4 Information Required in EQuIS EDDs An EDD is a tab-delimited text file containing environmental data in the EPA Region 4 format. Detailed information on all EDD formats may be found in the EPA Region 4 EDD Format File Guide. Table 2-1 is a check list of which EDD files are required based on the type of field activity. When planning field activities, consider the data requirements to ensure appropriate data collection and reporting to meet project objectives. Verify with your RPM if you should be completing other EDDs in addition to the required EDDs for the field activity. A brief summary of the more commonly used formats can be found below. Location EDDs – These EDDs provide coordinates for sampling locations, along with a simple indication of the quality of the information. Because all other EDDs rely upon this information, the Location EDD is the first EDD that is submitted. Field Results EDDs – These EDDs provide the results of field analyses (e.g., XRF, pH, temperature, turbidity, etc.). Water Level EDDs – These EDDs provide groundwater elevation data. If a water level EDD is submitted, a Location EDD with the ground surface elevation (measured to top of casing for wells) is required. In addition, each Water Level EDD must have a matching Well Datum EDD (EPAR4_WellDatum_v1) to identify the measuring point of the Water Level Depth. The Well Datum EDD is required when submitting water levels for the first time and any time a well is modified. Geology EDDs – These EDDs provide information about well construction, lithology, etc. If groundwater samples are to be submitted, the screening intervals must have been recorded using the well construction EDD (EPAR4_WellConstruction_v1). Analytical Data EDDs – Provide the fixed-base laboratory analytical data. The data is in a three- file format. EPA Region 4 SEMD Page 13 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 EPA Region 4 SEMD Page 14 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 2.5 Common Fields in EDDs With few exceptions, the values described below are the first four columns of all the EPA Region 4 EDDs. See the EPA Region 4 EDD Format File Guide for details on your specific EDD format. 2.5.1 Data Provider Codes (sampling_company) Data Provider codes are used to identify the source of the data within DART. For R4LIMS projects, the data provider code is selected within the Project Tracking System as the project is created. For all other projects, the data provider code is determined by R4DART (and is then provided to the data provider). If a data provider code does not exist in the system, R4DART will create one. 2.5.2 Project IDs (task_code) The Project ID is a unique identifier for all data collected during an investigation. It allows data from a given study to be retrieved by the original report with which it was submitted. For R4LIMS fund lead projects, the Project ID is generated by the R4LIMS Project System when the project is created. The Project ID is provided to data providers via the LSASD Project Tracking System email reporting system. For non R4LIMS projects, the data provider requests the Project ID from the R4DART.When Collect, EDGE or Scribe are used for the project, the Project ID is entered during the initial setup with the Site Information. 2.5.3 Project Numbers (task_code2) The Project Number is typically the same as the Project ID. These are unique identifiers for all data collected during an event for the investigation or when multiple laboratories are needed. The Project Number allows data from a given study to be retrieved by the original report with which it was submitted. For R4LIMS fund lead projects, the Project Numbers are generated by the R4LIMS Project System when the project is created. The Project Numbers are provided to data providers via the LSASD Project Log Summary Report email. For non R4LIMS projects, the Project Number may be the same as the Project ID provided by R4DART. If a unique Project Number is required to track an individual event, request a new Project Number from R4DART. When Collect, EDGE or Scribe are used for the project, the Project Number is entered during the chain-of-custody setup. 2.5.4 Program/Activity Codes (task_type) The Program/Activity code identifies the program activity associated with the sampling event to the DART database. EPA Region 4 SEMD Page 15 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 For R4LIMS lead projects, the Program/Activity code is provided by the person entering project data into the R4LIMS Project System. For non R4LIMS lead projects, the Program/Activity code is determined by the site manager (RPM or OSC) and is then provided to the data provider for entry into the activity_code in the EDD. When Collect, EDGE or Scribe are used for the project, the Program/Activity Code is entered during the initial setup with the Site Information. 2.5.5 Station IDs (sys_loc_code) A Station ID is the permanent designation for a sample collection point. Once a sampling point has been established, the Station ID designation will be used for all future sampling events regardless of the entity leading the investigation. Note that the sampling point is established for a location, not a sample type. A Station ID is not a Sample ID. Sample IDs should be distinct from Station IDs to prevent confusion. Station ID designations should be simple and easy to remember. Do not use special characters such as the asterisk, quote, or percent symbol. The Station ID should be kept to 8 or fewer characters where possible. For example, two samples are collected from the same location in Sandy Creek, sample SC-001- SW (a surface water sample) and SC-001-SD (a companion sediment sample). Because they were collected at the same location, both will have the same Station ID, such as SC001. Additional example, a soil sample is collected as a part of a monitoring well installation. The subsurface soil sample is designated RF-007C-SB. The well being installed is being given the designation MW012. Sample RF-007C-SB (and all other samples collected at that well location) will have the Station ID MW012. It may help to think of the Station ID as the permanent name for a sampling location, while any number of samples (from any media available) may be collected at that given location. A Station ID is a point on a map, and many samples may be collected from that point during an investigation (or series of investigations). All environmental samples must have a Station ID (e.g., surface water, groundwater, sediment, surface soil, etc.). Field blanks (trip blanks, equipment rinse blanks, etc.) do not have coordinates, and therefore, do not have Station IDs. The logic for this is built into EDP—if you try to enter a Station ID for a sample type (media code) that does not allow it, EDP will display an error. Likewise, if a media code requires a Station ID that is missing, EDP will again display an error. EPA Region 4 SEMD Page 16 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 3 EPA Lead Data Submittals 3.1 EPA Lead Projects Data from all EPA lead projects (LSASD, States and EPA contractor performing organizations) using EPA laboratory resources (CLP and special purchase laboratories) must be permanently archived in DART. It is the responsibility of the EPA manager (RPM or OSC) to ensure that the data provider(s) for the investigation properly prepare and submit all EDDs. All questions about data submittals for EPA Lead projects should be directed to: R4DART@epa.gov. Procedures for projects that are being conducted by PRPs can be found below (Section 4). 3.2 Software Requirements The software listed below is required for electronic submittal of data from EPA lead projects in the EPA Region 4. 3.2.1 Collect, EDGE, or Scribe EQuIS Collect and EDGE are both EarthSoft developed applications and can create a Scribe like deliverable. Scribe is an EPA developed and distributed software program that is used in the EPA Region 4 to generate EDD files of chain-of-custody information. EDGE is available for free at the EarthSoft website: https://earthsoft.com/products/edp/edp-format-for-epar4/. EQuIS Collect Mobile app is available for free from the Google Play Store, Apple App Store, or Microsoft Store. Scribe is available for free at: https://www.ertsupport.org/Scribe. In the EPA Region 4, these programs are used with DART to provide more compatibility between Element and DART, making EDD creation and submittal easier. If using Scribe, the EPA Region 4 samplers should obtain the EPA Region 4 template for the necessary customizations specific for the EPA Region 4 Scribe configuration from: https://response.epa.gov/site/doc_list.aspx?site_id=ScribeGIS. Select the Scribe Template from the right-side category listing. 3.2.2 EQuIS Data Processor EDP is used to check EDDs for errors prior to submission and to create the data package for submittal. It can also be used to create smaller EDDs. It is available as a free download, if the data provider does not have access to an EPA workstation. See Section 2.3 for more information on EDP Standalone. EPA Region 4 SEMD Page 17 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 3.3 Create Site or Waterbody 3.3.1 Site Creation Before data can be submitted, the site must be created in DART. Proper site\waterbody creation is important to success. DART is intended to be a permanent archive for the data generated by these investigations. For EPA lead projects conducted by LSASD, the Project Leader has the responsibility for Site or Waterbody creation. For EPA lead projects not conducted by LSASD, the EPA Region 4 program office will submit the required information. Site creation requests must be sent to: R4DART@epa.gov. Begin by checking with the R4DART coordinator to see if the site has been created. Internal to the EPA Region 4, anyone with access to the R4LIMS Project Information may check the dropdown for R4LIMS projects. If the site is not within DART, it must be created. To create a site in DART: • Search for the site at the SEMS website at: https://cumulis.epa.gov/supercpad/cursites/srchsites.cfm • Verify the search results, identify if there is an EPA ID recorded, and copy the URL (website address) from the search results and paste it into an email to R4DART@epa.gov requesting the site be created. • If the site is not found on the SEMS website or does not have an EPA ID, go to the EPA EnviroFacts website at: https://enviro.epa.gov/. • This will utilize a Multisystem query retrieval and may return several related sites. Find the site matching the address and if the site is found, select the Facility Report icon. When the page is updated, if there is an EPA Registry ID listed, copy the URL (website address) from the Facility report feature and paste it into an email to R4DART@epa.gov requesting the site be created. • If the site is not in these databases, send the following information to R4DART@epa.gov: Site Name Address, City, State, Zip Code County RPM/OSC Lat/Long of Site Centroid NPL Status 3.3.2 Waterbody Creation First contact the R4DART coordinator to see if the waterbody already exists in DART. If the waterbody does not exist in the EQuIS DART database, it must be created. EPA Region 4 SEMD Page 18 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 To create a waterbody in DART, the project leader must provide the USGS GNIS ID number for the Waterbody. The GNIS ID numbers for all waterbodies in the US can be found at this website: http://geonames.usgs.gov/. • At the website, select ‘Search Domestic Names’. • In the dialog box that opens, enter the ‘Feature Name’. • Select your ‘Feature Type’ and ‘State’. • Click ‘Submit Query’. • In the dialog box that opens, click the Feature Name for details. • Copy the URL (website address) of the page that opens and paste it into an email to R4DART@epa.gov requesting the waterbody be created. If the waterbody does not exist in the USGS database, send the best available name to R4DART@epa.gov. 3.3.3 Criminal and Enforcement Confidential If the field investigation is criminal or enforcement confidential, extra precaution must be taken to keep the project data confidential. For these investigations, determine if the site is in DART as outlined above. If found, check the Facility Code field. If it does not begin with ‘R4SC-‘, copy the name and Facility Code of the site and forward to R4DART@epa.gov with a request to create the site as criminal or enforcement confidential. If the site or waterbody does not exist in DART, find the needed information as outlined above (Sections 3.3.1 and 3.3.2) and forward to R4DART@epa.gov. The subject line of the email should state the site is for criminal or enforcement confidential data. If the site or waterbody cannot be found in the EPA or USGS databases, send the best available information to R4DART@epa.gov. The subject line of the email should state the site is for criminal or enforcement confidential data. 3.4 Project Creation (Project ID) For R4LIMS fund lead projects, after the project has been created but prior to the field investigation, the data provider will receive an email with the Project Log Summary information required to successfully submit an electronic chain-of-custody to LSASD. Use the information in this report to setup your investigation in Collect, EDGE or Scribe. When a project for the investigation is logged into the R4LIMS System, a Project ID is assigned and a project is automatically created in the R4LIMS System. The Project ID is then embedded in the EDDs and is used to tie that data to the original study. EPA Region 4 SEMD Page 19 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 For non R4LIMS projects, contact R4DART for the assigned Project ID. As part of the project setup for non R4LIMS projects, information about the types of data that will be collected (and EDDs submitted) should be sent to R4DART using the Data Submittal Summary Template. 3.5 Chain of Custody All EPA lead projects in the EPA Region 4 must submit an electronic chain-of-custody to LSASD. For all soil and sediment type sampling, a copy of the chain-of-custody XML file must also be sent to R4DART@epa.gov. This file can be generated using Collect, EDGE or Scribe. This EDD file is different in one major aspect from all other EDDs submitted from EPA lead projects: These chain-of-custody EDDs must be submitted to R4SampleCustody@epa.gov and cc R4DART@epa.gov. This submittal does not satisfy the requirement for a signed chain-of-custody to accompany the samples at all times. 3.6 DART Reports After your chain-of-custody data is received and the samples are logged into the R4LIMS (Element) system, you will receive automated reports if additional information or corrections are required. These emails are sent the night samples are logged into the R4LIMS (Element) system and each Monday thereafter. When all needed corrections have been made to Project Log and Element, the project setup in the Project Tracking System is checked to see what additional EDDs (Location, Field Results, Geology, or Water Level) are required. The data provider will receive at least one DART report from the Project Tracking System, even if no errors are found and no additional data are required. This is to allow for an opportunity to proof and correct the data in the system. 3.6.1 Sample Information Requests These email alerts are triggered by missing or incorrect information in Project Log or Element that will prevent the lab analytical data from loading to DART once reported. These corrections must be made before the data is reported by the LSASD laboratory. If the corrections are not made before the data is reported, it will be necessary for the lab to re-report the data. These emails contain a due date in the subject line. Corrections and missing data must be submitted prior to the due date. EPA Region 4 SEMD Page 20 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 3.6.1.1 Corrections to Project Log For R4LIMS lead projects, if the Project Summary report email shows information missing, forward the email to R4DART@epa.gov and supply the missing information. This portion of the report checks for: • Valid site or waterbody selected, • Valid Project ID selected, • Valid program\activity selected, and • Valid data provider selected. 3.6.1.2 Corrections to Element Errors within Element are not easily corrected when system information conflicts with the official hardcopy. Changes to Element must be accompanied by supporting information, such as corrected chain-of-custody, logbook information, and explanation (to attach to official documents in the file). Information presented in this portion of the email shows your sampling information as it currently resides in Element. Station IDs and Media Codes are checked to ensure compliance with business rules. If you have a missing or incorrect Station ID or Media Code, type the correct value in the appropriate ‘Edited’ column and forward the email to R4DART@epa.gov and cc R4SampleCustody@epa.gov. Should an error on the chain-of-custody be found after the samples and electronic chain-of- custody xml file have been sent to R4SampleCustody@epa.gov (cc R4DART@epa.gov), an updated electronic chain-of-custody needs to be recreated and then sent to R4COCCorrections@epa.gov and again cc R4DART@epa.gov. Errors of this type may be a mislabeled sample, the wrong location code used, or a date and time wrongfully entered. 3.6.2 EDD Requests These emails contain a due date in the subject line. Requested EDDs must be submitted prior to the due date. • After any errors in Project Log and Element are corrected, a Location EDD is requested for Station IDs that cannot be matched in DART. A weekly reminder to submit the Location EDD will be sent until the data are received. • Once the Location EDD has been received, requests for any additional EDDs will be sent based upon the information in the project setup. 3.6.3 ‘Overdue’ Reports If corrections and EDDs are not submitted before the analytical data is reported by the lab for R4LIMS lead projects, ‘Overdue’ reports will be generated. These reports will be sent each Monday morning until the requested data is received. EPA Region 4 SEMD Page 21 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 3.7 Creating EDDs EDDs can be created in a number of ways. The best method will depend upon the amount of data to be submitted, and how the chain-of-custody was generated. It should be noted that for small amounts of data, any of the EDD(s) listed below can be created directly in EDP. Detailed instructions for creating EDDs can be found in the EPA Region 4 EDD Format File Guide and the EPA Region 4 EQuIS Data Processor Reference Manual. 3.7.1 Location EDDs Each email request for a Location EDD has the list of missing Station IDs within the email body. Submit the required information via Location EDD as soon as possible and prior to the analytical data being generated. 3.7.2 Field Results EDDs Field results should be sent to DART as soon as the locations have been submitted. These are typically the direct measurements taken during the field event. In place of a CAS-RN, all field parameters use a FI- prefix for the code. Fields results are not permitted to be entered within the analytical results EDD. 3.7.3 Water Level EDDs Required for all groundwater elevation measurements and for all surface water elevation measurements tied to groundwater elevation. The measuring from datum must be recorded for the elevation to be calculated using the depth to water. 3.7.4 Geology EDDs It is recommended that these EDDs be prepared by professionals with experience with this type data. Details for the various formats are specified in the EPA Region 4 EDD Format File Guide. 3.7.5 Analytical Data EDDs Preparation of these files should be performed by individuals with experience in understanding unfiltered laboratory reports. The format is specified in the EPA Region 4 EDD Format File Guide. Element – Analytical data reported by the EPA Region 4 LIMS (Element) are formatted for EQuIS and are automatically loaded upon receipt of a valid Location EDD. This includes any samples that are shipped to the CLP. Subcontracts/Interagency Agreements – Any non-Element data must be placed in the EQuIS format by the data provider. To help ensure accuracy, the performing laboratory should be requested to report the data in the EPA Region 4 EQuIS format as part of the bid. If the data provider has been tasked to validate the data, then validation qualifiers, interpreted qualifiers, and the validation stage are added to the laboratory deliverable prior to error checking and submittal. EPA Region 4 SEMD Page 22 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 3.8 Error Checking with EQuIS Data Processor For information on obtaining, installing, maintaining and using EDP Standalone, refer to the EPA Region 4 EQuIS Data Processor Reference Manual. If you are using EDP Standalone, be sure the EPA Region 4 format and reference values are all up to date before using. If you are using EDP on an EPA workstation, start EDP by logging in to EQuIS Professional and selecting your site (facility). Once connected to the database, select the EDP icon in the upper left corner. Data Providers must use EDP to check all EDDs for errors before submission. EDP contains a help file to assist with error correction. Let the mouse hover over any cell with a non-white background to view a detailed error message. Hover the mouse over any column header to view additional information specific to the field. Instructions for using EDP can be found in the EPA Region 4 EQuIS Data Processor Reference Manual. When you email the EDD to EPAR4@EQuISOnline.com and there are errors, the system will automatically send the data provider an email that the EDD was rejected and an error log will be attached. If you are unable to correct the problem, email the EDD’s Error Log along with the file causing the problem to R4DART@epa.gov with your contact information. 3.9 Submitting EDDs After correcting any errors in your EDD, save the file from EDP using the sign and submit menu option to save the data package. A user name and password is required to successfully create the EDD package and upload the data into DART. If you do not have a valid user name and password for DART, email R4DART@epa.gov and provide the Site, RPM, data provider company, and data provider email address. After processing with EDP, the submitted file IS REQUIRED to be named according to the following convention that includes the following elements connected with underscores: • Task Code • Site Name • Data Provider Company Code • Date Submitting (YY MM DD) • Type (Loc-Location/Ch-Chemistry/FR-FieldResults/WL-WaterLevel/GEO-Geology/ WC-Well and Well Construction /VI-Vapor Intrusion) • .FacilityCode.EPAR4.dat For example: 13-0001_YourSite_ YourCompanyCode_19 01 08_Ch.110001224773.EPAR4.dat EPA Region 4 SEMD Page 23 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 NOTE: The EPA electronic mail system will reject files with a .zip format due to security concerns. To match how the EPA Region 4 laboratory submits EDDs, you must rename the EDD file extension from .zip to .dat before emailing the EDD to the EPA Region 4. Files must be submitted with the “.dat” extension. NOTE: The EPA electronic mail system will reject files with more than three (3) periods. Thus, it is important to connect the file naming elements using underscores rather than periods. If the EDD contains data for a field that will need to update values already in the database, use “EPAR4update.dat” rather than “EPAR4.dat”, which only merges the data. An example is replacing estimated coordinates with surveyed coordinates. Attach the EDD to the automated email you received requesting the sampling for R4LIMS lead projects and forward to EPAR4@EQuISonline.com. If the file is named improperly or not attached to the requesting email, it will be returned to the data provider. 3.10 Proofing and Corrections Notify the DART coordinator of any errors you find in the system. Send corrections to R4DART@epa.gov. After the data has been successfully loaded, an automated email will be sent to the data provider from EPAR4@EQuISOnline.com notifying that the file has been accepted and no errors were found. If the data are rejected, an automated email will be sent to the data provider from EPAR4@EQuISOnline.com with the error log attached as a .dat file. To open the error log, download the .dat file from the email and rename the file extension from .dat to .zip prior to opening. Once the errors have been corrected, recreate the EDD package following the same process as the original sign and submit. The one exception will be the file name, which may not be identical to any previous submissions. For each resubmittal, add a capital letter suffix (i.e., “A” then “B”, etc.) to the file name. After the “Type”, insert an underscore followed by the capital letter suffix (i.e., Type_A.FacilityCode). For example: 13-0001_YourSite_YourCompanyCode_19 01 08_Ch_A.110001224773.EPAR4.dat The data provider is responsible for the receipt of all automated emails based on the information provided when requesting a user name and password. Should the data provider not receive the automated emails regarding their EDD submission or feel an error was inaccurately returned, notify the EPA Region 4 at R4DART@epa.gov for any errors found. EPA Region 4 SEMD Page 24 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 4 PRP Lead Data Submittals 4.1 PRP Lead Projects Responsible Parties conducting environmental investigations in the EPA Region 4 for the Superfund program must report their data to the EPA Region 4 electronically. The types of data required to be submitted are outlined in Section 2.4. The responsible party is responsible for the information contained in the files submitted by the data provider. Address all data submittals questions to R4DART@epa.gov. Procedures for EPA lead projects can be found in Section 3. 4.2 Software Requirements All data providers are required to use EDP to check their data files for errors prior to submittal. EDP is software used to check all EDDs for errors prior to submittal and to create properly formatted data packages. EDP can also be used to create smaller EDDs. EDP is available as a free download. 4.3 Site Creation All National Priorities List sites in the EPA Region 4 have been created in DART. If, however, a site is found to be missing (or a new site is added to the NPL), it must first be created using information from EPA’s national database as described in Section 3.3.1. To create the site, the RPM or OSC must email the URL (website address) from their search results (SEMS or Envirofacts as detailed in Section 3.3.1) to R4DART@epa.gov. If the site is not in these databases, the RPM or OSC must send the following information to R4DART@epa.gov: Site Name Address, City, State, Zip Code County RPM/OSC Lat/Long of Site Centroid NPL Status 4.4 Project Creation (Project ID) For current and historical data (as defined in the EPA Region 4 EDD Format File Guide), the project must be created manually (assuming no past fund lead projects are available in the R4LIMS Project System). The R4DART coordinator will use the DART system to setup the proposed data submittal, and to get the data provider contact information (email address) in the system. EPA Region 4 SEMD Page 25 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 When the project has been successfully established, a report may be sent to the data provider containing any existing Station IDs and their coordinates. The data provider must review the report for existing sampling stations. If samples are to be collected (or were collected) at an existing Station, the established Station ID must be used. 4.5 Data Submittal Summary After the project is created, the EPA Region 4 will notify the data provider to submit the Data Submittal Summary for non R4LIMS sampling and email to R4DART@epa.gov for tracking. When this information has been received and accepted by the RPM, the R4DART will be prepared to receive the project data. Information on the Data Submittal Summary format can be found in the EPA Region 4 EDD Format File Guide and downloaded from the Superfund website at: http://www2.epa.gov/superfund/region-4-superfund-electronic-data-submission 4.6 DART Reports After the information from the Data Submittal Summary is entered into the Project Tracking System and accepted by the RPM, automated reports detailing any errors or additional information needed will be sent to the data provider. These emails are sent the night the Data Submittal Summary is loaded, and each Tuesday thereafter until all data for the given project has been received. Note the order for the data submittals below. This order is both dictated by a desire to offer data providers with the opportunity to review each step in the data submittal process, and by the database logic of DART. 4.6.1 Location EDD Request If the Data Submittal Summary contains additional information for an established sampling station, the data provider MUST use the Station ID(s) provided. Because the system will begin requesting the remaining EDDs upon receipt of the first Location EDD file, the data provider may prefer to submit all Station IDs in a single Location EDD file. Multiple Location EDDs may be submitted if needed. If the Location EDD is found to contain an error not related to the coordinates, the PRP must send a spreadsheet with a list of the incorrect and corrected information. For coordinates with errors (or if better coordinates become available), the original Location EDD may be edited and re-submitted. Delete the rows in the original Location EDD that do not need to be updated, edit the coordinates for the remaining rows, and re-submit to R4DART@epa.gov. The phrase ‘Updated coordinates’ should be in the subject line. EPA Region 4 SEMD Page 26 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 4.6.2 Other EDD Requests Upon receipt of the Location EDD, the Project Tracking System will make weekly requests for the remaining EDDs that were specified in the original Data Submittal Summary and accepted by the PRP. The remaining EDDs will be checked against Station IDs as they are received, and will be rejected if no matching Station ID can be found. 4.7 Creating EDDs EDDs can be created using spreadsheet software, directly in EDP, or in a word processor such as Notepad. More information about the file format can be found in the EPA Region 4 EDD Format File Guide. The best method for creating EDDs will depend upon the amount of data to be submitted. It should be noted that for small amounts of data, any of the EDD(s) listed below can be created directly in EDP. Detailed instructions for creating EDDs can be found in the EPA Region 4 EDD Format File Guide and the EPA Region 4 EQuIS Data Processor Reference Manual. 4.8 EQuIS Data Processor For information on obtaining, installing, maintaining, and using EDP Standalone, refer to the EPA Region 4 EQuIS Data Processor Reference Manual, and Section 2.3 of this guidance document. Use EDP to check all EDDs for errors before submission. EDP contains a help file to assist with error correction. Hover the mouse over any cell with a non-white background to view a detailed error message. Hover the mouse over any column header to view additional information specific to the field. If you have errors you are unable to correct, email the EDD’s Error Log along with the file(s) causing the problem to R4DART@epa.gov with your contact information. Place the site name and the Project ID in the subject line. If you need to update the EDP Standalone appearance options for 508 compliancy, email R4DART@epa.gov for assistance. 4.9 Submitting EDDs Remember to submit Location EDDs before submitting any other EDDs. The database structure requires locations to be loaded prior to all other environmental data. While EDP permits the submittal of combined EDDs, this feature is not fully supported in the EPA Region 4 implementation. Submit each EDD separately (except for Analytical EDDs, which are always submitted as a three file set, and first time water levels will need a well datum EDD together – See the EPA Region 4 EDD Format File Guide). EPA Region 4 SEMD Page 27 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 When all errors have been corrected, save the EDD(s) using ‘sign and submit’ (see EPA Region 4 EQuIS Data Processor Reference Manual). Name all files as specified below. Improperly named files will be returned to the data provider. The required names can also be found in the EDD request reports sent to the data provider. After processing with EDP, the submitted file IS REQUIRED to be named according to the following convention that includes the following elements connected with underscores: • Task Code • Site Name • Data Provider Company Code • Date Submitting (YY MM DD) • Type (Loc-Location/Ch-Chemistry/FR-FieldResults/WL-WaterLevel/GEO-Geology/ WC-Well and Well Construction /VI-Vapor Intrusion) • .FacilityCode.EPAR4.dat For example: P2013-0001_YourSite_ YourCompanyCode_19 01 08_Ch.110001224773.EPAR4.dat NOTE: The EPA electronic mail system will reject files with a .zip format due to security concerns. To match how the EPA Region 4 laboratory submits EDDs, you must rename the EDD file extension from .zip to .dat before emailing the EDD to the EPA Region 4. Files must be submitted with the “.dat” extension. If the EDD contains data for a field that will need to update values already in the database, use “EPAR4update.dat” rather than “EPAR4.dat”, which only merges the data. An example is replacing estimated coordinates with surveyed coordinates. To submit your prepared data package, attach the data package to the EDD request and forward to EPAR4@EQuISonline.com. Any time there has been a data request sent, data packages must be attached to the requesting report. 4.10 Proofing and Corrections After the data has been successfully loaded, an automated email will be sent to the data provider from EPAR4@EQuISOnline.com notifying that the file has been accepted and no errors were found. If the data is rejected, an automated email will be sent to the data provider from EPAR4@EQuISOnline.com with the error log attached as a .dat file. To open the error log, download the .dat file from the email and rename the file extensions from .dat to .zip prior to opening. Once the errors have been corrected, recreate the EDD package following the same process as the original sign and submit. The one exception will be the file name, which may not be identical to any previous submissions. For each resubmittal, add a capital letter suffix (i.e., “A” EPA Region 4 SEMD Page 28 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 then “B”, etc.) to the file name. After the “Type”, insert an underscore followed by the capital letter suffix (i.e., Type_A.FacilityCode). For example: P2013-0001_YourSite_ YourCompanyCode_19 01 08_Ch_A.110001224773.EPAR4.dat The data provider is responsible for the receipt of all automated emails based on the information provided when requesting a user name and password. Should the data provider not receive the automated emails regarding their EDD submission or feel an error was inaccurately returned, notify the EPA Region 4 at R4DART@epa.gov for any errors found. EPA Region 4 SEMD Page 29 of 29 Environmental Data Submission Effective Date: January 9, 2020 SEMDPROC-009-R0 5 Information Required in GIS Submittals Initial draft submittal and final version of spatially enabled files acquired or developed to support mapping, spatial analysis, and/or report generation by a data provider are considered property of the EPA Region 4 SEMD and are required to be submitted to the EPA Region 4. GIS data submittals must meet the project, metadata, organizational, and delivery requirements in acceptable GIS data formats as specified in the EPA Region 4 Geographic Information System Deliverable Guidance. GIS data and map files will be packaged into zip files and submitted electronically. All electronic submissions will require the completion of an online GIS Data Submittal form. This form and zip file(s) should contain all information necessary to understand the data submittal. The EPA Region 4 will not accept any GIS data that does not have this form completed and accompanying the submittal. To submit your GIS data to the EPA Region 4, please zip all files and use the link below to access the EPA Region 4 online GIS Data Submission form: https://arcg.is/1aDXya
