Process Materials - DuPont Fayetteville Works OEQ-CFVV_00032171 PECTIONONE Introductior This confimator-y sampling (CS) Workplan was developed in accordance with requirements set forth in Resource Conservation and Recovery Act (RCRA) Permit No- NCD047368642-RI (permit) issued by the North Carolina Department of Environment and Natural Resources (NCDENR) to the DuPont Fayetteville Works (site) on December 2, 1997. The permit stipulates that DuPont prepare a CS Workplan to determine if the solid waste management units (SWMUs) and area of concern (AOC) listed in Appendix A of the permit have released hazardous waste or hazardous waste constituents to the environment (Table 1). This Workplan includes a: J Characterization of the, facility, SWMUs, and AOC C3 Project management plan L3 Confirmatory sampling and analysis plan Z1 Data management plan The following references were consulted in preparation of this document- Characterization of Hazardous Waste Sites, ,4 Methods Manual: Volume II, Available Sampling Methods, EPA Publication No. 600/4-84-076, EPA Region TV LStandard Operating Procedures and Quality Assurance Manual, and North Carolina Hazardous Waste Permitting Branch Confirmatory Sampling Warkplan Guidance - Interim Drafi Final, July 1994. 1.1 BACKGROUND E-L du Pont de Nemours and Company (DuPont) owns and operates the .Fayetteville Works Plant in the Duart Township of Bladen County, North Carolina. The facility is located 15 miles southeast of the city of Fayetteville on N.C. Route 87, along the B laden-C umber] and county line (Figure 1). The DuPont property was purchased as several parcels from several families in 1970. The first manufacturing area of the Fayetteville Works was constructed in the early 1970s, The facility is currently a manufacturer of plastic sheeting, fluorochemicals, and intermediates for plastics manufacturing. A former manufacturing area, which was sold in 1992, produced nylon strapping and Elastomeric Tape, The geographic location of the facility is 34"50'30" North latitude, 78'50'00" West longitude. The site contains 2177 acres cif relatively flat farmland and woodland bounded on the east by the Cape bear River, N,C, Highway 87 on the west, and farmland on the north and south. In addition to the manufacturing operations, DuPont operates a wastewater treatment plant (wwrp) for treatment of process waste. Hazardous waste generated as a result of the chemical process and laboratory analyses are currently managed in drums at the Hazardous Waste Container Storage Area prior to being shipped offsite for treatment, disposal, or recycling. In September 1993, a RCRA Facility Assessment (RFA) was submitted to the NCDENR, The RFA was resubmitted in December 1996 and identifies 24 SWMUs and four AOCs at the site. A Ago& figure identifying the location of these units is provided in Appendix A. Based in part on the RFA, the NCDENR identified three SWMUs and one AQC that require CS and are the subject of this Workplan (Figure 2). W66d..&C"e 4:XDSPA4103NCSVVPrEXT.DOC110-Feb-90105FA4103%PHI DEQ-CFW-00032172 mNt 0 1.1.1 Plant Site Operations 113troduction The DuPont Fayetteville Works consists of three main areas, where the following products are manufactured: Area 1 0 Butacite(& polyvinyl butyral sheeting - the plastic inner layer of automotive safety glass. Area 11 0 Nafiong Fluorocarbon membrane for electrolic cells. * Fluorocarbon intermediates for Naflong membrane, Teflon(P) resin, and Vitong elastomers. * Polysiloxane Abrasion Resistance Coating (PARC), Area.111 & Dymetrolg nylon strapping, 0 EPS Elastomeric tape for tape drives such as auto window regulators. 1.1.2 Regulatory The Fayetteville Works operates under permits from several regulatory programs; CR-A/solid waste, NPI)ES/water quality and air. 7V RCRA/Sofid Waste Permits: The facility received its initial RC: RA Permit (NCD047368642) to operate a hazardous waste container storage area and tanks in February of 1983. An amended Part A application was last submitted in 1991 to document upgrades to its fluorocarbon waste treatment and tank system. 11 The RCRA Part B permit application submitted in August 1993, identified a total of 71,750 gallons of container storage capacity at the container storage area. Waste stored included characteristic wastes (DOO I, D002, D003, D007, D009, and D029) and listed wastes (F002, F003, and F005). This permit was reissued and became effective on January 1, 1998, and will remain effective for 10 years, NPIDESAVater_Quality Permits: The Fayetteville Works also operates under a National Pollutant Discharge Elimination System (NPDES) Permit No- NCO003573 with discharge to the Cape Fear River. The earliest known water pollution control activity associated with the site was the issuance of a temporary discharge permit by the North Carolina State Stream Sanitation Committee. Since the original permit, this facility has been continuously permitted, holding discharge permits issued by the North Carolina Department of Water and Air Resources, and more recently, by the EPA/state NPDF-S branches, The most current NPDES permit will expire May 31,2001. W—dwa-1-cwe CO J:Z5FA410MCSWPTEXT, 00C%1 O-Feb,9805FAA I 03BPHI 1-2 DEQ-CFW-00032173 "16ECTIONONE Introductior Air Qualily, Permits, The Fayetteville Works currently has permitted air emissions sources. These sources are associated with boilers, process equipment such as exhaust stacks, condensers, mist eliminators, scrubbers, filters, and tank vents. The State regulatory agency established a system of source registration in 1971 and changed to emissions permitting in 1974. Permit requests were submitted to the State for the Fayetteville Works on an as -needed basis between 1971 and 1978. During the mid-1980's NCDENR began combining emissions permits into one or two facility emission permits. Presently, the. Fayetteville Works has all sources combined under one permit (No. 3735R,17), which is under continuous modifications as new sources are added to the facility. The objective of the CS is to determine if any of the units listed in Appendix A of the RCRA Part B permit have released hazardous waste, or hazardous waste constituents (Table 1). A release may be indicated by the discovery of any constituent previously or currently managed in a SWMU or A discovered by virtue of its detection in media beyond the engineered boundary of the unit and in concentrations of organic compounds above Practical Quanitation Limits (PQLs) or concentrations of"metals above the 95 percent Upper Tolerance Limit (95 percent UTL) for background soil concentrations. If a release is identified, then the unit will require a RR to dekm-nine the extent and impact of the release - A secondary objective of the CS is to provide data that will assist in the prioritization of those units that require an RFI. The purpose of this prioritization is to identify those units that pose the most potential for harm to human health and the environment. The prioritization will support risk management decisions making an effort to best utilize DuPont and NCDENR resources. wo.o..&C" 40 JA05FA4'fOMSWRTEXT DOr-%10-Vob-9MD6FA410MPH1 1-3 DEQ-CFW-00032174 Facility Characterization 2.1 REGIONAL SETTING The DuPont Fayetteville Works is located on 2,177 acres, 15 miles southeast of the City of Fayetteville at the Cumberland-13 laden County line. The site is bounded on the east by the Cape Fear River and on the west by NC 87- This area is characterized by generally low topographic relict' except along the west side of the Cape Fear River, The majority of the site is located on a relatively flat plateau with an elevation of approximately 145 feet above mean sea level (MSL). Relief is more moderate on the northern portion of the property along Willis Creek, west of the Cape Fear River, and near the Georgia Branch located in the southern region of the site. Slopes near the drainage areas range from approximately five to 20 percent while the slope on the plateau is generally less than 0.5 percent. The DuPont Fayetteville Works is located on the boundary between Cumberland and Bladen Counties with 75 percent of the land within Bladen County- This area is entirely within the Coastal Plan Physiographic Province, The Coastal Plain consists of a seaward thickening wedge of sedimentary deposits ranging in age frorn Cretaceous to Recent. These deposits are underlain by Paleozoic age metamorphic and Igneous rocks. In the northern Bladen County these "basement" rocks are approximately 400 feet below the surface. 10 The `Tuscaloosa Formation (also known as the Middendorf Fm.) of late Cretaceous age unconformably overlies the basement rocks. This formation consists of red, gray and yellow interbedded sands and clays. The sand layers are lenticular, poorly sorted and arkosic. The clay luycr� are massive, and dominate the formation in outcrop. Unconformably overlying the Tuscaloosa Formation, the Black Creek Fon-nation can be found at the surface in Bladen and Southern Cumberland Counties- In outcrop, the Black Creek is composed of dark gray, fine grained sandy clay and very fine to coarse sand. It is dark gray to black in the subsurface or in fresh exposures and brick red where it has been deeply weathered. The formatioi-I is approximately 300 feet thick in northern Bladen- Thc Duplin Marl of'Miocene age outcrops in a few areas along the Cape Fear River where it fills irregular depressions in the Black Creek Formation. The marl is composed of gray shells in a matrix of gray gilt and fine to medium sand. Surface deposits that cover much of the area are thought to be Pleistocene in age. They consist of white to tan very fine to coarse sand associated with a mottled tan sandy clay. Locally, the thickest deposits are found east of the Cape Fear River, while on the west side of the river they are often absent. The soil on the Fayetteville Works Plant site falls within the Norfolk -Goldsboro -Rains general classification (Soil Survey of Bladen County, 1990). These soils are on old, high stream terraces III the northern part ol'Bladen County- They range in being well to poorly drained soils that have a sandy or loamy surface layer and a loamy subsoil.

The layers of sand within the Black Creek Formation supply much of the groundwater locally, especially for the larger supply wells. The surficial deposits in the site area provide water for many small domestic wells. It is assumed that the general groundwater flow in the site area would be to the east toward the Cape Fear River. However, a natural high point directly east of the former WWT'P lagoons directs the groundwater flow in that area to the southwest and northwest, and if the groundwater flow follows the area's surface topography, it would eventually turn back to the east toward the river. *4�1 k I a 001041c] M Thl a VEM L, 113 11 111,111 Ll The Cape Fear River is located along the eastern boundary of the Fayetteville Works approximately 1850 feet away fTom the manufacturing and associated buildings. Willis Creek, a tributary of the Cape Fear Rivef is located in the northern portion of the site approximately 3,000 feet away from the manufacturing area. An effluent channel leading to the Cape Fear River is located ,just south of the plant and is used as the outfall area covered by NPDES Permit number NCO03573. Only parts of the Georgia Branch are within the southern boundary of the site. Surface water runoff firom the manufacturing areas which are not captured by the process sewer system, are captured by the storm sewer system and is directed to the wood -lined ditch which also discharges into the effluent channel. The plant facilities are located on a plateau area approximately 70 feet above the 100 and 500 year flood plains and at least 1,000 feet from the 100 year flood plains nearest approach.

The locations of each SWMU and AOC included in the CS are shown in Figure 2. These areas are discussed in terms of the dates of operation, unit and waste characterization, and potential migration pathways. Unit characterization describes the location, operational history, operational status, construction, and processes of each SWMU/AOC. Waste characterization describes the wastes managed by the units. Migration pathways define the environmental medium most likely to be impacted by a release from the unit- In most if not all cases, soil is the initial medium impacted by a release from a unit; hence, soils below the CS units will be the focus of the investigation. The RFA also provides a description of these units. The SWIG Us/AOC identified in the Hazardous Waste Management Permit as requiring a CS are- • SWMU 6 - Process Sewer System ❑ SWMU 7 - Storm Sewer System ❑ SWMU 9 (A, B Sr. Q - Former WWTP Lagoons ❑ AOC-C - Former Ag Products Gasoline/Diesel UST Area MUNE13 "M •�t1 Date of Operation. 1972 to present Unit Characterization SWMLJ 6 is a system of underground sewer pipes, manholes, and sumps which convey process wastewater from the main plant areas to the site's WWTP system (Figure 3)_ Plant personnel and site sewer map,,, indicate that the pipes are constructed of reinforced concrete, vitrified clay and steel. There are four process sewer sumps throughout the plant and all are in -ground and constructed of reinforced concrete these include the following: Butaciteg sump; PVA sump' Nation (P common sump-, Semiworks sump, All sumps are concrete -lined, and the Na one common sump is also polylined- Waste Characterization The unit manages wastewater from the ButaciteT) Area, DymetrolS Area, Naflong Area and Power House Area. The wastewater may contain any of the wastes generated or raw materials managed at the facility. Based on interviews with DuPont personnel, Appendix D contains a list of process materials that may be found in small quantities in the process sewer system. The following is a brief description of the waste streams from each process area that may enter the process sewer system'.

The Nafiong internal process sewers notTnaliy contain only cooling waster or steam condensate. During floor washing, small quantities of process materials and lute oils may be washed into the sumps. Closed sumps within the Naflont area are tested for pH and the presence of a heavy fluorocarbon liquid phase. If pH. is not neutral or if a fluorocarbon phase is detected, the sump material is drummed for disposal by incineration. Butaciteg Area: The process sewer from the Butacitek area contains process wastewater, cooling water, steam condensate, rain water and filtered water. a Power House Area. The waste stream that enters the process sewer system from the Power House Area consists of sulfuric acid and caustic from the neutralization sump and tank. Releases from SWMLJ 6 would impact soil and potentially groundwater. TA [Tj RZANUS i'l a Vjjji Dates of Operation: 1972 to present SWMU 7 consists of asysten-i of sumps, drains and ditches located throughout the plant which collect stormwater that is eventually routed to the Cape Fear River. The storm sewer system is constructed of earthen drainage ditches and a wood lined ditch, The stormwater collection system is designed to handle a combined rate of approximately 13,900 gallons per minute (gpm) Engineering control devices are in place to prevent the mixture and/or contact with plant process constituents, Rainfall accumulated in permed chemical containment areas and other engineered spill containment structures are routed through the process sewer system after the waters have been tested and approved for such discharge. Confirmatory sampling is being focused on a small section of the storm sewer system where solid polyvinyl alcohol (PVA) particles were observed in the storm sewer system actiacent to the PVA unloading area of the Butacite(-R) area, Methanol is normally present in PVA and is a likely contaminant resulting from the PVA being present in the storm sewer. This section of the storm sewer is shown on Figure 5. The unit manages storm water from throughout the plant- Small amounts of PVA from the rail 40 car unloading area have reportedly been conveyed to the storm sewer through surface water runoff.

FORMER WWTP LAGOONS Dates of Operation: Lagoons A & B 1979 to 1990 Lagoon C 1972 to 1979 Unit Characterization SWMU 9 A and B. consists cif unlined lagoons used for the settling of sediments from process and sanitary wastewater. From 1979 until the current WWTP was completed, these lagoons served as biosludge settlement lagoons for the plant's wastewater before discharging to the Cape Fear River. These lagoons replaced SWMU 9 C lagoons prior to the startup of the Nafione area. The lagoons were inground, trapezoidal in. shape and consisted of approximately eight impoundment cells. SWMU 9 A and B dimensions were approximately 180 feet by 270 feet by 6 feet and were located east of the existing WWTP. The lagoons were made up of several impoundment cells that were operated by alternately filling the cell with treated effluent, letting Am& the sludge settle, then decanting the supernate to the WWTP. The two lagoons (SWMU 9 A and B) were dismantled in 1990. A plate and frame filter press was used to process the sludge present in the lagoon, Filtrate generated by sludge processing was returned to the WWTP. Sludge residuals that remained on the lagoons bottoms and sides after primary sludge processing, were removed. Cement kiln dust was used to bind any free liquid to insure scrapings passed the paint filter test. The lagoons were backfilled with the same soil that was removed to construct them. The sludge and scrapings were properly disposed of at the 13171 Sampson County Landfill. SWMU 9.C. were the first lagoons constructed at the facility in 1972- SWMU 9 C was constructed by building earthen berms using the soil excavated when the original Equalization Basin and original clarifier were built for the WWTP. The lagoons were constructed to handle blOSIUdge. generated at the WWTP from the Butaciteg process. The lagoons were operated by filling separate impoundment cells one at a time, letting the sludge settle, then decanting the supernate to the WWTP. Prior to the startup of the Naflon 9 process, SWMU 9 C lagoons had become full of sludge and Were closed. SWMU 9 A and B lagoons were constructed to replace SWMU 9 C. The locations of the former WWTP lagoons are shown on Figure 6, Waste Characterization SWMU 9 A and B received both process and sanitary waste from throughout the facility. However SWMU 9 C received process and sanitary waste from the Butacite(& area only. W-odwa-J-CW. GI JI1)5FA410ICSWPTEXr.

Potential releases from these SWMUs would primarily be to the subsurface soil and gToundwater. A system of groundwater monitoring wells has been installed as per NCDENR requirements. The wells in the area of this unit were designed 10 monitor impacts to the groundwater from past activities. The monitoring wells are constructed of either 2 inch or 4 inch diameter PVC pipe. Each well has a 5 foot screen with standard gravel packing - Date of Operation. 1977 to 1989 This area consisted of three 1,000 gallon underground storage tanks that contained gasoline and diesel fuel (42 fuel oil) used in association with the Agricultural Products test farm area. The tanks were removed in 1989. The holes were backfilled after tank removal and are now an unused, grass covered area. Figure 7 shows the location of AOC-C, .4 Waste Characterization These tanks handled gasoline and diesel fuel. The tanks were made of metal and were removed intact with no visual holes or defects noted at the time of removal. After the tanks were removed the tank excavations were also inspected for any sign of leakage and none was found. Releases from the tanks would impact soil and potentially groundwater. 3!1D5FA41031CSWPTEXT.DOC6IG-Fab-984[)5FA4102PHI 3-4 DEQ-CFW-00032180 A14 Project Management Plan 'Phis Project Management Plan (PMP) has been prepared by W-C Diamond Group as part of the Workplan preparation effort for implementation of a RCRA CS at the DuPont Fayetteville Works. The purpose of a PMP is to communicate and document the management approach for the project. The PMP contains the following sections, ❑ Technical approach D Project Schedule ❑ Persorwel (including roles and responsibilities) This PMP is intended as a supplement to the CS Workplan. Each project team member identified below will be familiar with the, CS Workplan. Additional documents (e.g., Waste Management Plan, Health and Safety Plan (HASP), field notes logbook, sample status logbook, etc.) may be developed as part of the pre -field mobilization effort as needed to ensure that all field activities are completed safely and effectively. The technical approach employed for this project will include: ❑ Selecting qualified personnel to perform management and technical duties 1* • Field investigation 0 Data review and interpretation 0 Project management 0 Report preparation activities U Effectively managing the personnel and project to meet the objectives of the CS Workplan ❑ Assembling and reviewing available data pertaining to site and technical studies 0 Executing effective investigative studies, as described in the CS Workplan ❑ Analyzing data and interpreting findings ❑ Presenting the data, findings, and conclusions resulting from the investigations ❑ Communicating with NCDENR (as required) The CS Workplan outlines an investigation that will be performed to determine if a release of hazardous constituents have occurred from the SWMUs and AOC listed in the permit as requiring CS (Table 1). If a release of hazardous constituents is determined to have occurred frorn a particular unit, a recommendation will be made to NCDENR to progress to the next phase of investigation, the RFI Workplan. If no releases have occurred from a particular unit, based on 10 the data, a recommendation of no further action will be made. Woodward.cwe W J;=FA4103%C34VPTEXT.17=1 O•Fao-WOUA4103%PH 1 4-1 DEQ-CFW-00032181 Project Management Plan The CS Workplan also describes the development and use of a Conceptual Evaluation Model (CEM) which will be used to prioritize all of the units that will require an RFL The CEM will be used to compare the relative potential for a unit, Or group of units, to pose a threat to human health and the environment. Based on the results of this evaluation, a risk management decision can be made regarding which units should be addressed first. A schedule has been developed for implementation of the CS Workplan and is presented in Appendix B. The duration of specift tasks reflect the current understanding that DuPont has regarding the scope of each task and is based on the experience of implementing similar programs at other DuPont facilities. Since implementation of the CS depends upon NCDF-NR approval of the CS Workplan, no fixed dates have been indicated on the schedule. DuPont understands that the CS is the first phase in a multi -phased RFI (if required). Since each phase builds on the preceding phase, a detailed schedule for the entire program cannot be completed at this time. If the CS phase of the investigation indicates a release of hazardous constituents from a particular unit, an, updated schedule will be prepared for the next phase of the investigation, the RFI Workplan. 91 9 0 N 1* 4 _161 to] N NO DuPont and W-C Diamond Group have carefully assembled a to of highly qualified professionals for the CS project possessing the knowledge and experience necessary to fulfill the needs of the Fayetteville CS.

The RR Guidance Document (EPA Publication 530/SW-89-03 1) was used to develop monitoring and data collection elements of this Workplan. All analyses will be perfon-ned in accordance with procedures described in Test Methods for Evaluating Solid Waste, PhysicallChemical Methods, EPA Publication SW-846 [Third Edition (September 1986), as amended by Update I (July 1992)]. As described in the PMP in Section 4.0, the CS is the, first phase in a multi -phased RFL Only CS activities are described herein. Groundwater and soil (surface and subsurface) will be sampled during the CS. Unit -specific soil investigations will be performed to provide preliminary information on elevated constituent levels within or near the units. Urtit-9pecific groundwater investigations may be performed to determine groundwater elevation and flow direction, and to provide preliminary information on elevated constituent levels in the groundwater near the unit. Sampling locations and depths have been carefully selected to provide samples representative of site conditions, and biased.to sample the most likely point of release. Based on facility records and the RFA for DuPont Fayetteville Works (DERS, 1993 revised 1996), analytical parameters for each sample have been determined by considering knowledge of the waste and constituents handled in the units and the operational history of the units. In SWMUs where a variety of wastes could possibly have been managed, a 46 more extensive list of analytical parameters, such as volatile organics, will be implemented. For units with a well-defined operational history, a more specific sampling and analysis plan is applicable. The field procedures outlined in the guidance documents in Appendix C will be followed during all phases of the field investigations or variance will be noted- The data management plan in Section 6-0 details the use and presentation of collected data. ReleawsOf Organic constituents from the units will be determined by comparing the reported constituents to background which is assumed to be non -detect. An organic constituent release will be. confirmed for a unit if reported concentrations exceed the PQL. Also, releases of metals from a unit will be determined by comparing the analytical results to background concentrations for the metals listed on Table 2- ` o determine site background concentrations of metals, 4 soil borings will be advanced to approximately 12 feet below ground level (8GL). Figure 2 shows the proposed locations for the background soil borings. Soil samples will be collected at intervals which are geologically equivalent to sampling horizons around the MMUs. (i.e., background metal samples consisting of unsaturated surficial aquifer material will be collected for comparison to samples collected in that same horizon near a SWMU). A total of at least 12 soil samples (three per boring) Will be collected. 'Soil samples will be analyzed for the metals listed in Table 2. WbodWard-Chda W J1D5FA41034GSVVPTEXT. DOC% 1 O-Feb-MD5FA4 1 03TH1 5-1 DEQ-CFW-00032184 SECTIONFIVE Confirmatory Sampling And Analysis Plan 10 Background concentrations will be calculated using the UTL approach described in Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities {EPA, 1989a). The UTL is the upper limit of the tolerance interval which establishes a concentration that contains a specified portion (P) of the population with a specified level of confidence (Y). For calculation of background concentrations, a P of 95 percent and a Y of 95 percent will be used. Thus, there is a 95 percent confidence that the calculated UTL will contain 95 percent of the distribution of background concentrations for each constituent. .Procedures for calculating tolerance limits are detailed in Section 6.4.1. Soil samples will be classified by soil horizon and compared to background U'ri,s from the same horizon. Borings will be advanced using a GeoprobeTM or hollow -stem augers, and soil samples will be collected in split -barrel samplers or Shelby tubes. Some areas of the site may be inaccessible to drilling rigs, in those areas, a stainless steel hand auger will be used to collect samples. For logging purposes, all borings will be continuously sampled, but only the sampling intervals specified in each SWMU will be collected for laboratory analysis. Appropriate guidance documents are provided in Appendix C. Table ') describes soil boring depths and number of borings at each SWMU, and Table 4 summarizes the analytical parameters. All soil sample analyses will be reported on a dry weight basis to meet the requirements of the NCDENR Division of Waste Management- If groundwater elevation is above the base of the unit for 01 SWMU 6 and AC C - C, groundwater samples wwill be collect in lieu of soil samples for that unit. During the sampling activities, all work will be monitored with an organic vapor detector, such as a flame ionization detector (FID), as a means of assessing the presence of volatiles in soil at the various sampling locations. Other monitoring may be conducted to fulfill requirements of the pro ' iect HASP, All samples will be collected, preserved, transported, and analyzed in accordance with the guidance documents in Appendix C. All solid wastes generated will be placed into 55-gallon drums and scaled for final disposition at a later date. To avoid cross -contamination between sample locations, all field equipment will be decontarninated before use at each boring location, in accordance with guidance documents included in Appendix C. The groundwater investigation portion of the CS will focus on potential releases from SWMU 9 A, 13, and C and SWN4U 6 or ACC - C where the base of the unit is below the water table. Groundwater information collected from sarnple points, monitoring wells and temporary wells will be used to depict groundwater flow direction. Samples collected downgradient will be compared to upgradient samples for that area of investigation. If no significant increase in groundwater concentration levels exists between the upgradient and downgradient wells, and no elevated concentrations are detected in the downgradient groundwater and surrounding soil 110 samples (relative to site background information), then data from both media will confirm that no release has occurred.

The monitoring wells near SWMU 9 A, B, and C will be sampled within the same time period. If groundwater elevations are determined to be above the invert of SWMU 6 or ACC - C groundwater samples will be collected from GeoprobeTA pre -packed screens installed within the soil boring. To minimize turbidity and the effects of drilling, groundwater samples will be collected from the temporary wells a minimum of 48 hours following completion and development. Water levels will be measured in newly installed wells and existing wells ill the vicinity of the investigated SWMUs with an electronic water level indicator. Water level measurements in new and existing wells will be perfom-ied prior to sampling groundwater. Methods for purging and sampling monitor wells are detailed in the guidance documents in Appendix C and include methods described in the RCR,4 Groundwater Monitoring Guidance (EPA, 1992a) and in EP,4 Region IV &andard Operaling Procedures and Qualify Assurance Manual (FPA, 199 ]a), Analytical methods for background and SWMU soil and groundwater samples are listed in Tables'-), 4, and 5, 5.5 SAMPLING LOCATIONt Boring locations for each unit were selected using process and historical knowledge to determine where releases were likely to have occurred- If no information is available to predetermine soil -sample locations, then the borings will be located adjacent to the unit, and the soil samples will be, taken immediately below the base. Borings located within a unit shall not damage an engineered unit. Boring locations of units without well-defined boundaries (i.e., WWTP Lagoons) will be located within the known area. Samples will be taken below the base of the unit in native soils, VFM- Rnlq=- r 3 A total of 9 soil borings will be completed adjacent to the process sewer system. Sample locations were selected based on observations made during a January 1998 site inspection. Nine soil borings will be completed along the sides of pipes and pipe joints along the entire process sewer system (Figures 3 and 4). Soil boring locations were selected near sumps, lift stations and manholes where several process sewer lines converge. These locations were selected because they represent worst case locations for leakage around joints and connections. Soil samples will be collected from the base of the sewer line to two feet into natural soil (Table 3). The borings will be terminated at the first occurrence of saturated soils.

Samples collected along the process sewer trunk will be analyzed for the combination of all contaminants. It should be noted that analytical methods are not available for all of the process materials that may be found in trace quantities in the process sewer system.

A total of two shallow soil samples will be completed along the storm sewer drainage ditch adjacent to and dowaigradlent of the PVA unloading area where PVA flakes were observed in the storm sewer system (Figure 5). One soil sample will be collected for analysis from each location at 0 to 2 feet below the base of the storm sewer channel to determine if a release to soil has occurred. Samples will be analyzed for potential source materials that, according to existing records, could be present in this SWMU, Since PVA was observed in the storm sewer system and methanol is normally present in PVA, the samples will be analyzed for methanol_ EPAAnalysis Method(s) Because PVA is the only contaminant known to have entered the storm sewer system, the soil samples will be analyzed for methanol by Method 801 5B, ;Vill Six soil borings will be advanced around the Former WWTP Lagoons (Figure 6).

For the p1q meter, buffers will be at pH 4, pH 7, and pH 10. Two of the three buffers will be used to calibrate the meter. The pH 7 buffer is always one of the calibration buffers, and the second buffer (pH 4 or pH 10) will be consistent with the parameters of the samples collected in the field. if the samples are acidic, then the pH meter will be calibrated with the pH 4 buffer. If the samples are alkaline, then the pH meter will be calibrated with the pH 10 buffer. If the sample parameters for pH cannot be determined prior to calibration, then one buffer, either pH 4 or pH 10, will be used to calibrate the pH meter. If pH 4 is selected and the pH of the collected sample is above 7, then the pH meter will be recalibrated with the pH 10 buffer and the sample will be reanalyzed with the final result recorded in the field notebook- Likewise for the pH 10 buffer, if it is selected and the pH of the collected sample is below 7, then the pH meter will be recalibrated with the pH 4 buffer, and the sample will be reanalyzed- The buffers will be purchased from a laboratory chemical supply, and the exact pH will be noted in the field notebook. For the conductivity meter, reference solutions will be in the range of 1,000 µomhs/cm. The median standard will be used for calibration checks.

The sample number will indicate the type of sample media and the sampling location. The sample media will be indicated by the format of the sample name. A SWMU number and depth will be included in the sample name for soil samples. A monitor well (N4W) number (and no sample depth) will be included for groundwater samples. For example, the first soil sample collected at SWMU 6, Sampling Station Number 1, could be assigned the code: FVW nSW6 LU, LMXWV� --01 sitQ (Fayetteville Situ) SW M or Sample Location Number Depth (feet) 3a= CS data will be arranged and presented to facilitate interpretation and understanding of this information as it pertains to the overall objectives of the investigation. Typical data displays include tabulation of measurements and observations and graphical displays to summarize information as it relates to conditions present at the site. It is anticipated that raw data will be evaluated predominantly through use of the appropriate tables and screening procedures to evaluate outliers and to produce data summaries. Final data will be assessed using a variety of summary procedures, including tabular and graphic forms. v"= J3D5FA4103%CSWWTEXT DQQ%10-Feb-98%D5FA4103%PH1 6-2 DEQ-CFW-00032198 SECTIONSIX Tabular Displays Data Management Plan Raw data will be presented and evaluated in tabular form using electronic spread sheets.

Once raw data have been screened and the QC assessment has been completed, final tables and displays will be prepared- AM1�'inal project data will be displayed, where applicable, using a variety of graphical methods to AalloI and development ofa clear understanding of the sampling locations, areas where more data are needed, and levels of constituents at each sampling location. Spatial distribution of constituents found will be examined through displaying constituent concentrations on site facility maps representing the various sampling points. Where appropriate, maps will be prepared to indicate groundwater flow, changes in concentration in relation to distances from the source, and constituent concentration patterns. Features affecting intermedia transport will be displayed, as well as identification of potential receptors. Subsurface information will be displayed using vertical profiles and cross -sections to allow an examination of the change in impacts to soil or groundwater with depth. This type of display also will allow an examination of substrata- Hydrogeologic cross -sections will be used as appropriate to evaluate more fully the relationship of groundwater to potential releases from the site. At the present time, it is not anticipated that three-dimensional plots and stratigraphy fence diagrams will be necessary for description of features present at the site. Data collected during the CS investigation will be evaluated using statistical methods. Background concentrations will be established for naturally occurring substances such as metals for comparison with substance concentrations detected during the CS. The steps that will be AMR&. followed to statistically evaluate the data are- Woodward-C"o 40 JAQ5rA4103NCSWPTEXT 13QC%1G-FQb-98)05FA410MPH 1 6-3 DEQ-CFW-00032199 SECTIONSIX • Distribution testing • Handling, of nondetect values • Calculation of tolerance limits • Comparison of discrete sample values to limits Data Management Plan The calculations of tolerance limits and comparisons of discrete sample values are detailed in Section 6-4. Data Collection Planning The first -step in planning a statistical evaluation of a data set is to determine the requisite size of the data set. The distribution of the data will be tested to determine if the data set is normally or lognormally distributed (or nonnomial). Normal and lognormal distribution will be tested by observing a probability plot of the untransformed and the natural log transforrn of the data. Lognormality A06 Re will also be tested by calculating the Shapiro -Wilkes test statistic (EPA, 1989a and 1992b). The statistical method used in deriving the UTL (for background data) or the upper confidence limit (UCL) (fbr site data) will be dependent upon the distribution of the data. Nondetects in normally distributed data (ifnondelects are less than IS percent of the data set) will be handled by substituting the detection limit for the nondetect value, If the data are normally distributed and nondetects are greater than 15 percent of the data set, then Cohen's method will be used- lithe data are lognormafly distributed, nondetects will be handled using the Probability Plot method (also known as Helsel's Robust method), A criterion for determining whether a release has occurred from SWMUs/AOC included in the CS will be a comparison of sample data with area background concentrations. For organic AWIL. compounds, "background" concentrations will be the PQL. For naturally occurring substances, background concentrations will be those concentrations that occur in areas of the facility that have, not been affected by industrial activities. Waodwanf;-C� IV JAWAA I 0MG6WPrEXT.DQC%1 O-F e6-981D$FA410MPH1 6-4 DEQ-CFW-00032200 IECTIONSIX Data Management Plar The CS activities typically are not intended to generate sufficient numbers of samples from each environmental medium associated with a SWMU to allow generation of statistically -derived upper bound concentrations- As a result, maximum concentrations of naturally occurring chemical constituents detected at each SWMU investigated will be used as the basis for the comparison with background concentrations. This approach introduces a high level of conservatism. Data will be collected to characterize area background concentrations of naturally occurring substances in soil. 'The concentrations of naturally occurring chemical constituents in the background data will be used in the risk assessment to determine the presence of chemical constituents that might have been introduced to the environmental medium under evaluation as a result of industrial activities (Le., site -related), Background concentrations of naturally occurring substance,, in soils will be represented by collecting a set of 12 soil samples. Background concentrations of naturally occurring chemical constituents in groundwater will be obtained from published background values for the area - The UTL will be derived from background samples collected for soil samples only. The statistical method used in deriving UTLs will be dependent on the distribution (i.e., normal, lognormal, or nonnormal) of the data. is Calculation of Tolerance Limits After the underlying distribution of the data set is determined and nondetect values are evaluated, the UTI, of the data set will be calculated according to the appropriate distribution. For normally distributed data: Where: UTL = x + ks X � Sample mean k = Tolerance factor (95 percent coverage, 95 percent confidence) S = Standard deviation For lognormally distributed data: UTI, = e {x + ks) Where: X = Sample mean k = 'Tolerance factor (95 percent coverage, 95 percent confidence) 10 S = Standard deviation e = 2,718 Wbodward-C"a W J:%D5FA410MCSVIJPTP_XT DOCM-Feb-98%D5FA4103NPHI 6-5 DEQ-CFW-00032201 SECTIONSIX Data management Plan For nonparametric data sets, the UTL is assumed to be the maximum value of the data set, according to EPA guidance (EPA, 1992b), Discrete sample concentrations of the field sampling data will be compared to the background UTL concentrations. If the sample concentration is less than or equal to the background UTL concentration, then the sample may be assumed to be a me-mber of the background population. If a particular constituent in a field sample has a concentration greater than the background 1.31-L, then the constituent may be assumed to be a member of a population different from the background population. However, due to the nature of the UTL calculation, it is possible that as much as five percent of the true background population exceeds the UTL (EPA, 1992b). Thus, if less than five percent of the samples exceed the background UTL for a given constituent in a given area, the constituent may not be considered to be present above what could be expected from samples collected from a naturally occurring distribution of that constituent. All units designated for investigation in the RF1, by exhibiting a release as determined by this CS effort, will be subject to prioritization. The objective of the prioritization effort is to identify those units on the DuPont Fayetteville Works that have the greatest potential to adversely affect human health or the environment. Once the unit prioritization process has been completed, the RF1 can be focused on first investigating the higher priority units. Lower priority units may be addressed in order of importance (i.e., medium and low priority) at a later stage in the Corrective Action process. Prioritization ofthe SWMUs/AOCs will be performed by applying available site -specific information contained in the CEM and, when appropriate, professional judgment to determine which units (if any) are the most significant contributors to health and environmental risk. Prioritization will be based on the unit's potential to: 0 Cause fire/eNplosion or pose some other serious safety hazard 11 Release significantly beyond the perceived boundary of the unit :1 Adversely affect the health of'human (and, in some situations, ecological) receptors that might come in direct contact with affected media within the unit LJ Migrate to other environmental media such as air. groundwater, surface water, and sediments 13 Migrate to off -site receptors-, both human and ecological J.MSFAA1 031CSVVPTEXT.DQC%1 G.Feb•MDSFAA I 03TH 1 6-6 DEQ-CFW-00032202 SECTIONSIX Data Management Plan An excellent source of information to be used in creating the CEM unit prioritization process is NCDENR's Guidance. for the Use of RCRA National Corrective Action Priorilization System (NCAPS) in North Carolina, which was published on August 29,1995 (NCDENR, 1995). The guidance was based largely on the USEPA's NCAPS system to tank Hazardous Waste Treatment Storage and Disposal Facilities (TSDFs) in the United States. NCDENR augmented the EPA guidance with information, such as climatological information, that is specific to the state to allow for ranking of facilities located in North Carolina. The NCDENR NCAPS prioritization system will serve as ab.asis for the development of the CEM and prioritization of RFI units. The NCAPS scoring system is divided into four sections, namely groundwater, surface water, air, and on -site- Although the final criteria to be used in prioritizing the units have not been selected at this time, minimum criteria have been decided and consist of the following: D Confirmation and significance of release from each unit. Sample data collected from the CS or other activities at the facility forms the basis for such determination. However, in the absence of sample data, information included in documents such as the R-FA is critical to determining the confirmation or potential significance of a release, 40 El ldentification of the potential for migration to groundwater, such as the depth to groundwater, the net annual precipitation in an area, and the physical state (e.g., solid, liquid, gas) of the materials disposed in or present at each unit. Q Integrity of any containment systems that might be present at some or all units. Whether the unit exists as a surface impoundment, as a container/tank, as a pile of solid material, or as a landfill is significant to the evaluation of integrity. 0 Toxicity and persistence of'chemical constituents that are confirmed to be present or, in the absence ol'analytical data, that might be. present within a unit, D If'available, the quantities of waste materials that might have been disposed of within a unit. 0 Potential receptors and area groundwater use patterns in the vicinity of a unit. D Distances from a unit to the nearest potential receptors. �@- 0 Presence of an observed release from a unit, either by surface runoff or by discharge of groundwater into a nearby surface water body. D Physical and chemical characteristics of a chemical substance that are conducive to migration potential to surface water. 0 Integrity of unit in respect to containment.

The actual ranking of each criterion listed above will be quantitative, as presented in the NCAPS guidance. There also will be a need for subjective ranking, such as when there is a professional judgment input that is appropriate. Professional judgment criteria that will be considered include such factors as the existence of additional regulatory controls that apply at the units (i.e., -NPDES or solid waste), community concerns, and any additional site -specific information relevant to the prioritization process. Any additional criteria that might become relevant when the units are prioritized will be incorporated subjectively into the priontization. Weighting of some criteria over others, also a subjective criterion, likely will be considered when the prioritization is performed. When subjective inputs are part of the prioritization process, the reasoning behind such inputs will be included in the text of the CS Report. A limited amount of additional information regarding the site's environmental characteristics beyond that which presently exists or will be provided by this CS effort may be desirable to provide the appropriate level of infom-lation to support the prioritization process and resulting recommendations, If additional analytical data is deemed necessary and/or appropriate, DuPont will communicate and coordinate with NCDENR any sampling efforts that will be conducted to provide this information. a 4:;DSPA41035CSV4PTEXT.DOCNIO-Pa8-981t)5FA41035PHI 6-9 DEQ-CFW-00032205 SECTIONSEVEN Confirmatory Samplino Report The results of the investigation will be presented according to the schedule in Appendix B.

Potential huards are addressed in the Health and Safety Plan (HASP). This procedure must be carried out in the following rnamer: I - Be aware of safety- Don appropriate personal protective equipment (PPE), as prescribed by the project HASP for the project. 2. Locate the desired monitoring well using a current site map. Note the following information in the field notebook or sampling data sheets: date, time, job site location, well identification nw-nber, ambient weather conditions, name of sampling personnel, purge method and equipment, and any other field observations such as well box condition, standing water, etc- 11151 FVIMIMSJIMM�= T1 R 4. Check for the presence of volatile hydrocarbons in the well headspace with a calibrate-i photo ionization detector (PID)/flame ionization detector (FID). Record thrt. measurement, Take any additional safety precautions as indicated in the HASP for the headspace gas reading recorded. 5, If the well is known not to contain light non -aqueous phase liquid (LNAPL), take the depth -to -water measurement in the well using an electronic water level meter. Other -wise, use an interface probe to measure the LNAPL thickness and depth to water. Record all measurements in the field log, 6. Using the electronic water level meter or the interface probe, lower the probe end of the meter or interface probe until it touches the bottom of the well. 7, Holding the measuring tape near the measuring reference point, alternately raise and lower the probe to get an accurate feel of the bottom of the well. Record this measurement in the field log. S. Calculate the total volume of standing water within the well casing.

If a bailer is to be used, attach a sufficient length of new rope to the bailer. H. If a centrifugal, peristaltic, or, bladder pump is to be used, attach sufficient hose to the pump and lower it into the well. 12, Begin purging the well, The well should be purged at a rate low enough to prevent water from cascading down the sides of the well, if at all possible. 13. When no sediments are visible in the purging water, connect the water quality meters. 14, Measure the temperature, electrical conductivity, and pH of the water withdrawn from the well. Record these values in the field log. Repeat the measurements at regular intervals. 15. Continue purging the well until the measured parameters stabilize, to within 10 percent for two consecutive measurement. If the measured parameters do not stabilize, five well volumes should be removed, At this point, the well is ready for sampling. 16- If the well is purged to dryness or is purged such that recovery exceeds two full hours, the well should be sampled as soon as a sufficient volume of groundwater has entered the well to enable the collection of the necessary groundwater samples.

This procedure must be carried out in the following manner. I - Be aware of safety, Don appropriate personal protective equipment (PPE), prescribed by the project Health and Safety Plan for the site. i 2. Be certain that measured groundwater parameters have stabilized. 3. The choice of sampling containers, preservation, and holding times should be based on consideration of the desired analytes. 4- When using a bailer, care must be taken to minimize agitation or aeration of the 14 water; ibis could lead to the loss of volatiles and to a nonrepresentative sample. The decontaminated bailer should be lowered slowly into the well, filled, and then lifted out while preventing the bailer or the rope from contacting my potentially contaminated surface, such as the ground. 5- The more volatile samples sbould be collected first. For example, volatile organic analysis (VOA) bottles and total organic halide (TOX) should be filled first, followed by serni-volatile organics, inorganics, and metals. 6. Care must be taken to prevent the sample container rim or cap from contacting any potentially contarninated surface such as fingers, rope, bailer, or pump tubing. 7- When pouring from the bailer, direct a slow, steady stream of water into the sample container, trying to minimize the aeration of the sample. 8. For sample containers with septums, fill the sample container to the top of the container so that a meniscus is formed. Allow any air bubbles to rise to the surface. Carefully and quickly screw the cap onto the container and finger tighten.

These hazards will be addressed in the job -specific Health and Safety Plan. PENEWMEW Of This procedure must be carried out in the following manner; 1. Be aware of safety. Don appropriate personal protective equipment (PPE), as prescribed by the project Health and Safety Plan. The use of this instrument itself requires no special PPE. 2, The instrument is recharged by connecting the charger. This should be performed the night before field use. 3. Unscrew the metal sample tube from the rest of the unit to check that the porous aluminurn air filter is not dirty or missing. Also note that the outside surface of the filter must be inside the sample tube. Without the filter, readings will be extremely erratic. Put the sample tube back on the instrument, 4. Depress the "On/Off" key. This powers the lamp and starts the sample pump. Aix - should now be pulled into the instrument through the sample tube. 5. Calibration of the instrument should be performed as per the attached instructions. First the instrument baseline should be set to zero using the "zero air." 6, Then the "span gas" (the isobutylene) is used to calibrate over a range. Span gas should be of a practical range (100 and 250 ppin are good). 7. When the flow regulator is being removed from the cylinder, it will pop off at the end of the threads. This is not a hazard, but be sure to hold the regulator firmly as it is unthreaded. 8. After calibration is complete, return the instrument to "Run" mode. Calibration should be done every day. The instrument does not have to be running, however, to hold calibration. APN'1203.d; CO3VF1DENrZAL 23[QMMM= DEQ-CFW-00032249 Revised: May-95 Revision A. I Page 2 of 5 9. As a check for the instrument, pass a source of volatiles (such as correction fluid or a marker) near the sample tube. The instrument should register a value. An alternate check is to half` fill the Tedlar& bag with the span gas, and check the concentration in run mode. If the instrument registers within approximately +/-10pereent, then calibration is still valid. 2.1 Special Conqiderations/Requiremeuts/Equipment Personnel implementing this guidance document should ensure that the following are in place: 13 "White -Out" correction fluid or permanent marker * "Zero air" cylinder * Constant flow pressure regulator Isobatylene cylinder J Model 580E Portable organic vapor monitor (OVM) 13 TedlarOD bag 0 Tf.&O) tubing assembly Optional Equipment: L) Communications software 13 Communication,, cable C3 Percale -female gender changer 1, Volatile chemicals that have an Ionization Potential (IP in eV) greater than the IP of the PID lamp are undetectable by that lamp. 2- High humidity interferes with the readings of the instrument. 3. Chemicals with a different response factor than isobutylene may give readings higher or lower than the actual concentration, 4, The instrument assumes a linear response of signal to concentration. When a concentration greatly exceeds the concentration of the span gas, the value becomes increasingly inaccurate.

Be aware of safety- Don appropriate personal protective equipment (PPE), as prescribed by the project Health and Safety Plan for the project. 2. Prior to installing a well or a piezometer, a bore hole mast first be advanced to the required depth (see Guideline 5002 for hollow -stem auger drilling procedures, or Guideline 5001 of rotary drilling procedures). Well/piezometer installation takes place at Step 8 of Guideline 5002, or at Step 8 of Guideline 5001. 3. The diameter of the well to be installed will depend on the, intended use for the well and possible engineering considerations and needs. A minimum two-inch annular space is required between the borehole and the casing (for example the inner diameter of the auger used to install a four -inch well shale be 8-1/4 inches). When drilling with hollow -stem augers, the inside diameter of the augers is what must be measured to determine borehole size. 4, All well screen and well casing used should be new and of adequate structural integrity, and should be made of material that will be compatible with the contwnination present (or anticipated), Screen size should be determined using sieve analysis. Screen length should be adequate to monitor the zone of interest, and in general should not be less than five feet long nor greater than 20 feet. lower the section into the open bore hole. For piezometers, solid well casing will be perforated over a specified length, a threaded sump placed on the bottom of the casing, and the casing will then be lowered into the open bore hole, CONFIDENTIAL APPC4101,doc DEQ-CFW-00032254 INSTALLATION OF MONITORING/INJECTION/RECOVIER YYOBSERVATION WELLS, AND PIEZOMETERS /GUIDELINE NO. 4101 Revised: May-95 Revision No, I Page 2 of 4 Teflonll� tape can be used to wrap the threads to ensure a tight fit and minimize leakage. Teflon'& "0" rings can also be used ("0" rings made of other materials are not �icceptable if the well is to be sampled for organic compounds). 6. Thread additional lengths of well screen together, as needed, until the appropriate total well screen length is achieved. Do not use cement or glue. T Thread solid well casing (in 10-foot lengths) onto the well screen section to complete the well to a height approximately two feet above the ground surface. Do not use cement or glue. Centralizers should be placed on wells greater than 50 feet. T. Once the well screen and casing have been placed in the bore hole, place filter pack material in the annulus between the bore hole wall and the well screen. The type of filter pack material used will depend on the intended use of the well and the geologic f0mation that the bore hole penetrates (sieve analysis). 9. Pour a minimum of six inches of the filter pack material under the bottom of the well screen to provide a firm footing and unrestricted flow under the screened area. Filter pack should extend a minimum of two feet above the top of the well screen, and should be placed by a tremie pipe where possible. If drilling with hollow -stem augers, the augers should be lifted as the sand is tremied into the borehole. If it is impracticable to tremie the filter pack, pouring the sand is acceptable in shallow bore holes (less than 50 feet), where the annular space is large enough to prevent bridging. The level of the filter pack materials must be measured at appropriate intervals to ensure no bridging has occurred. 10. Once the filter pack material has been placed, place a seat above the filter pack in the annulus of the bore hole to provide a watertight seal. The seal should be a minimum of two feet thick and should consist of a minimum of 20 percent solids bentonite. This type of bentonite is available in either powder or pellet form. The preferred method of placing either bentonite pellets or a bentonite powder/water mixture is by tremie pipe. If this method is not practicable (pellets only), pouring the pellets is acceptable in shallow bore holes (less than 50 feet), where the annular space is large enough to prevent bridging. The pellets must be tamped, and measured at appropriate intervals to ensure they have not bridged.

May - Revision No. Page 3 o Fq The bentonite seal must be allowed to hydrate for eight hours or the manufacturer's recommended hydration time, whichever is greater. Measure the seal after hydration time to ensure that the required two feet of seal is present. 1. After the bentonite seal has hydrated, grout the remainder of the borehole to prevent surface water infiltration. 12. The grout, material used will conform to applicable local, state, or federal regulations. Unless otherwise specified, the grout will be a mixture of Portland cement and bentonite powder. The grout will have a minimum density of 9.4 lbs/gal (going in and coming out of the hole) to ensure proper set-up. The grout density should be measured with a mud balance. 13. Once the grout has been mixed, tremle it into the annulus between the well casing and the bore hole wall. Remove the drill rig auger flights/steel casing that remain in the bore hole as the grout mixture is added. Be sure to leave the auger flights/steel casing at least one foot below the top of the grout, to prevent caving of the bore hole. Unless otherwise specified, the grout will be allowed to handle a minimum of 24 hours before well development. 14. For well protection and security, install a steel protective casing with locking cap approximately three feet above the surface (two feet below). If the well is installed in a roadway, install the steel protective casing to a height slightly above the road surface to prevent inflow of surface waters. Well protection and security may differ if engineering remediation design dictates the necessity for something different The outer protective casing should be installed into the borehole a minimum of 24 hours after the grout has been poured. 15. Prior to the use of a well or piezometer, well development must be perforTned to rest the natural hydraulic properties of the formation that were disturbed during drill operations (see Guideline 4102 for well development procedures). 16. Decontaminate all equipment prior to moving to the next location. See Guideline 720] for procedures concerning equipment decontamination.

Well development occurs a minimurn of 24 hours after the installation of monitoring wells, recovery wells, injection wells, observation wells, and piezometers (see Guideline 410 1). Either a truck -mounted hydraulic surge block, a submersible pump, or bailer are used to develop a well. 3. Prior to initial surging of the well, purge the well of approximately three to five well bore volumes to clear out any fine sediments that accumulated in the well during installation. A submersible pump or bailer can be used to purge the well. 4. Slowly lower the surge block into the well, using a truck -mounted hydraulic winch, until it is near the top of the screened section. 5- Using the hydraulic winch, alternately raise and lower the surge block through a vertical distance of one to two feet- The velocity of the surge block motion will depend on the tightness of the formation in which the well is installed. 6, After surging the well a few times at a given depth, move the surge block deeper into the well by one or two feet and repeat Step S. 7, Repeat Steps 5 and 6 until the surge block has been lowered to the bottom of the screened section of the well. 8, Slowly raise the surge block out of the well. 9.

Prior to drilling, inform Utilities Locating Service so that any underground utilities in the vicinity of the drilling site can be marked and identified. 3. If possible, use a hand auger to advance a hole where the drilling is to take place, and use a hand-held locator to check for the presence of any underground pipes or cables. 4. When using water rotary, the potable water that is to be used must be analyzed for the 40 contaminants of concern prior to drilling_ When using air rotary, the air compressor most have an in -line organic filter system to filter the air coming from the compressor. When using mud rotary, only pre -analyzed potable water and bentonite drilling muds may be used. All drilling materials must have adequate manufacturer documentation for material use and constituents. 5. The water, air, or mud forced down the drill pipe, escapes through small ports at the bottom of the di -ill bit, thereby lifting the cuttings and cooling the bit. The cuttings are blown out of the top of the hole where they collect at the surface around the borehole. As these cuttings collect, periodically remove them and place them on polyethylene sheeting to avoid any possible leaching of contaminants that may be present. 6. Initially, advance the borehole at a slow rate as an extra precaution, so that any possiblo contact with underground utilities will be less damaging, 7. If sampling or geotechnical evaluation is to take place during drilling, advancement the borehole can be temporarily halted and the drill pipe removed from the borehol thereby allowing the undistui-bed soil immediately beneath the borehole to be sampl or evaluated (see Guidelines 1403 or 1406 for operating procedures for vario sampling and testing techxiiques).

During the first five to seven feet of drilling, the hollow stem auger is advanced at a slow rate as an extra precaution so that any possible contact with underground utilities will be less damaging, L] 5. Hollow -stem auger flights are five feet in length, therefore drilling is temporarily halted at five-foot intervals so that additional auger flights can be attached. Auger flights are attached to one another by threaded ends and bolts. Only TeflonO "0" rings are acceptable to make augers watertight. 6, As excavated soil accumulates at the top of the bore hole, it is shoveled into a wheelbarrow and moved out of the, way.

Potential hazards will be addressed in the project Health and Safety Plan. This procedure must be carried out in the following manner: 1. Be aware of safety. 2, Obtain a chain -of -custody and fill out all appropriate areas, including: analytical laboratory address, type of analysis, number and type of samples, turnaround time, etc. Sign the chain -of- custody as the "Relinquisher." 3, For glass sample containers, first place the sample container in shipping foam or a bubble -pack wrapper to protect it from possible breakage during shipment. 4- If using, place the metal sample liners or cylinders into a Ziplocv plastic bag to prevent any possible moisture ftom reaching the soil samples. Glass sample containers should be wrapped in bubble wrap or placed in foam molds to prevent breakage. 5. Place the metal sample liners or sample containers into a large plastic bag and place the bag into an ice chest. 6. Fill the bag with ice. Seal the bag by twisting and taping with strapping tape to prevent leakage. Place packing material into the ice chest to fill any voids, if needed, to prevent movement of the sample containers during shipment, 7. If the analytical laboratory sends a representative to pick up the ice chest, have the representative sign the chain -of -custody as the "Receiver." If the ice chest is to be shipped to the analytical laboratory, the lab representative receiving the ice chest will open the ice chest, check the containers, sign the chain -of -custody as the "Receiver," make a photocopy of the chain -of -custody, and will send the photocopy back to the "Relinquisher."
