Project Operations Plan (POP) has been prepared by Sirrine Environmental Consultants (SEC) for the Macon/Dockery Site Remedial Investigation/Feasibility Study (RI/FS) at the direction of the Macon/Dockery Site Steering Committee. The RI/FS is being prepared under an Administrative . Order of Consent agreed upon between the Site Steering , Committee and the United States Environmental Protection Agency (EPA) Region IV in April, 1988. The Work Plan for the Macon/Dockery site was approved by EPA Region IV following its submittal in March, 1989 (RI/FS Work Plan, Macon/Dockery Site; C. T. Main, March, 1989). The purpose of the POP is to provide detailed procedures for conducting the RI activities specified in the Work Plan. The POP combines two previously separate documents, the Quality Assurance Project Plan (QAPP) and the Field Sampling Plan (FSP), as directed by the EPA guidance document (EPA, 1988b). General requirements of the FSP include: Site Background Project Objectives • Sample Location and Frequency • Sample Designation Sampling Equipment and Procedures • Sampling Handling and Analysis Requirements of the QAPP include: • Project Description • Project Organization and Responsibilities 1 I I I I I I I I I I I I • I m g n u D • • • • QA Objectives Field Investigation Procedures Sample Custody Calibration Procedures Analytical Procedures Data Reduction, Validation, and Reporting Internal Quality Control Performance and Systems Audits ' Preventative Maintenance Data Assessment Corrective Actions In addition, the Health and Safety Plan to be used during the RI/FS effort has been included as Section 4.0 of this document. The POP has been prepared in accordance with the following documents: • • National Oil and Hazardous Substances Contingency Plan (EPA, 1985a) Guidance on Remedial Investigations Under CERCLA (EPA, 1985b) Interim Final Guidance for Conducting Remedial Investigations and Feasibility Studies Under CERCLA (EPA, 1988b) EPA -Region IV Standard Operating Procedures and Quality Assurance Manual (EPA, 1986c) The POP is subject to revision throughout the investigation to accommodate each phase of the RI process and unexpected field conditions. Any changes to POP procedures or sampling locations will be documented in writing to the EPA-Region IV Regional Project Manager (RPM) or his designated representative. 2 I I I I I I I g g D D D D I I • I I I 1.2 SITE LOCATION AND HISTORY The Charles Macon Drum and Lagoon Site and the Dockery Site, collectively referred to as the Macon/Dockery Site, are located in Richmond County, North Carolina. The Macon/Dockery Site is located approximately 1.6 miles southwest of Cordova, North Carolina and 0. 76 miles east of the Pee Dee River on State Road (SR) 1103. The Mac_on and Dockery properties are not contiguous. The Dockery property is located approximately 500 feet north of the Macon property on the west side of SR 1103 (Figure 1.1 ). The , combined area of the two.sites is approximately 17 acres. The Macon Site is located,at 34· 53' 30" north latitude, 79· 50' 18" west longitude,' and the Dockery Site is located at 34" 53' 52" north latitude, 79· 50' 18" west longitude. The Macon/Dockery Site was operated as a waste oil recycling and antifreeze manufacturing facility from 1979 to 1982. Following investigations by the North Carolina Department of Human Resources (DHR) and EPA, the Macon/Dockery Site was placed on the National Priorities List (NPL) in 1987. An Administrative Order by Consent between the EPA and the Respondents, Clark Equipment Company and Crown Cork and Seal Company, dated April 13, 1988, made provisions for a RI/FS in order to define the extent of environmental contamination if any and to identify and evaluate remedial alternatives. A RI/FS Work Plan for the Macon/Dockery Site was submitted by the respondents on March 27, 1989 and subsequently approved by EPA. From 1979 to 1982, Charles Macon operated a waste oil reclamation and antifreeze manufacturing facility at the Macon property. Drums containing waste paints, solvents, acids.and bases were also received and stored on-site. Waste oils were collected in 11 unlined lagoons on the Macon property and one unlined lagoon on the Dockery property. 3 I D D D D D SCALE 1:24 000 1•• ~I \ • , . .... -~66ij~~1::::J.. ..... ; /\ . ~ .

The details of subsequent investigations and actions by both OHR ,:ind the EPA are detailed in Section 1.3 of the Macon/Dockery Site Work Plan, March, 1989 .. The Work Plan also provides details of quantities and types of waste materials removed from the site during clean-up operations completed in January, 1984. 1.3 SITE DESCRIPTION 1.3.1 General Information For the purposes of this investigation, the Macon and Dockery Sites have been divided into the upper and lower Macon Sites and the upper and lower Dockery Sites. The upper site in each case is located adjacent to SR 1103 near the topographic ridge east of the sites. The lower site in each case is located topographically downgradient and west of the upper site. The Macon and Dockery properties are not contiguous. The Dockery property is located approximately 500 feet north of the Macon property on the west side of SR 1103. The Dockery Site is wooded with few cleared areas. One lagoon as well as several drum disposal areas were located at this site. A single unpaved road provides access to the site from SR 1103. Aerial photographs indicate that drums were deposited from SR 1103 west along the access road for approximately 600 to 700 feet. The lagoon on the Dockery Site was located about 2,400 feet west of SR 1103. The single lagoon was unlined and open areas around the lagoon were used for drum storage . The Macon property is approximately 60% wooded. Several cleared areas are present where buildings, lagoons, and drum disposal areas were located. The majority of oil reclamation activity occurred on the east side of the property adjacent to the SR. Two 5 I I I I I I I g u 0 H D D I I m I I I lagoons were located in a cleared area on the southwest side of the property. Three empty and apparently unused lagoons were located in the central portion of the lower Macon site adjacent to an orchard. 1.3.2 General Site Physiography/Geology The site is located on the western margin of the Sandhills Region of the Atlantic Coastal Plain. The topography in this area is generally smooth with extensive gently rolling interstream areas (Figure 1.1). Along the Pee Dee River, the topography becomes more rugged with deeply dissected stream valleys where tributaries flow into the river. The Macon/Dockery Site slopes moderately from a ridge toward the Pee Dee River from an approximate elevation of 275 feet mean sea level (MSL) near and parallel to SR 1103 to approximately 160 feet MSL at the western boundary of the sites. A broad, flat alluvial plain approximately 2,000 feet wide is located about 1,000 feet west of the site adjacent to the Pee Dee River. Surface water on the Macon Site drains to the west. Water which exits the northern portion of the site enters either a pond located west of the site or an unnamed first order tributary to Solomons Creek. Water exiting the southern portion of the site is ' expected to directly enter Solomons Creek. Solomons Creek enters the Pee Dee River approximately two miles downstream from where site runoff would be expected to enter Solomons Creek. Surface runoff from the Dockery Site exits the site via numerous gullies and intermittent streams. Water leaving the northern portion of the site enters a westward flowing first order tributary to the Pee Dee River. The tributary enters the Pee Dee River approximately one mile west of the site. Water leaving the southern portion of 6 I I I I m I m D D D I I m I I I I I I the site enters the same unnamed tributary to Solomons Creek as water leaving the northern portion of the Macon Site. Water from the Dockery Site enters the tributary approximately one-half mile upstream from the Macon Site. The site is located on the western margin of the Sandhills region of the Inner Coastal Plain Physiographic Province. The Sandhills region is characterized by deep sandy soil, rolling topography, and the highest elevations in the Coastal Plain. The lithology, as indicated by its name, consists of r~latively horizontal, interfingered marine deposits which slope approximately 15 feet per mile eastward toward the Atlantic Ocean. The Cretaceous Age Middendorf Formation crops out at the site. More detailed geologic information is presented in the Macon/Dockery Work Plan. Ground water at the Macon/Dockery Site is mainly derived from infiltration of precipitation through the soil. Ground water exists in primary pore spaces within the upper sediments and lower weathered residuum. The depth to ground water ranges from approximately 27 feet below surface at well MW-1, east of SR 1103 on the upper Macon site, to about 37 feet in well MW-4. Many domestic water wells in the vicinity of the site are less than 70 feet deep. 1.4 PROJECT OBJECTIVES The limited investigations of the Macon/Dockery Site to date have not adequately determined the extent of potential contamination of soils and ground water. The objective of the RI is to obtain the additional data necessary to characterize the site and determine potential risks to human health and the environment. The objective of the FS is to evaluate the results of the RI and provide a basis for selection of a cost effective remedial action that is protective of human health and the environment. 7 I I I I I I • I 0 D I I • I I I I I I Based on the data collected, the objectives of the RI are to: Determine the nature and extent of soil contamination, if any, . • Determine the surficial or buried presence of any remaining drums or other containerized waste materials, • Determine the nature and extent of ground water contamination, if any, Determine the potential mechanisms for off-site transportation of contamination, Identify potential receptors and analyze the predicted impact of contaminatfon ' on off-site receptors, Identify potential areas for remediation . Specific tasks will include sampling of soils, ground water, surface water, and streambed sediment plus a geologic and a hydrogeologic assessment of the site and surrounding areas. The RI field investigations will be conducted in a series of phases to allow for adequate evaluation of data collected in each step and for refinement of proposed sampling locations and analytical parameters. To provide better overall source characterization and assist in expediting the RI effort within the required schedule, certain sampling activities originally designated for Phase II have been coupled with previous Phase I Work Plan activities. The Phase I investigation will consist of a source area characterization, an initial hydrogeologic assessment, surface soil, groundwater, surface water and streambed sediment sampling . The Phase I activities consist of both source area characterization and media-specific investigations. A surface geophysical survey will be conducted to locate possible buried metallic material such as drums or tanks. Direct source area sampling will be conducted in former lagoon areas to evaluate the potential for residual waste materials. Addition'al surficial soil sample collection will be conducted in areas where waste storage is suspected. An initial evaluation of hydrogeologic conditions will be conducted to aid in the Phase II hydrogeologic investigation. Surface water and streambed sediment samples will also be 8 I I I • m D I I I I I I I I I I I I I collected during Phase I to evaluate possible contaminant transport pathways. Characterization analyses, including the designated Target Compound List (TCL) and Target Analyte List (TAL) parameters, will be conducted on Phase I samples as. outlined in the approved Work Plan. Results from the Phase I Characterization analyses will be used to develop a proposed list of indicator parameters to be used for analyses of the Phase II samples. The indicator parameters list will consist of TCL/TAL parameters detected 1in Phase I samples. The primary field activities to be conducted during Phase II consist of monitoring well installation· and ground wat~r sampling. The objectives and major elements of each phase are outlined below. Objectives of the Phase I Field Investigations are: Investigate the potential presence of residual sources of contamination at the site, • Characterize residual sources of contamination which may be present, Provide an initial assessment of the horizontal extent of residual sources and soil contamination which may be present at the site, Develop a set of site-specific indicator parameters for use during subsequent sampling and analyses, • Provide initial characterization of the geology and hydrogeology of the site to guide subsequent assessment efforts, • Provide an initial assessment of the potential presence of ground water contamination resulting from former activities at the site, • Characterize the nature of ground water contamination which may be present and ground water flow directions at the site, • Provide an initial assessment of potential surface water and streambed sediment transport pathways. 9 I I I I I n D • I I I I I I I I I I I Phase I Field Activities will include: • • • Development of a site base map, A surface geophysical survey to identify potential buried disposal areas, Initial source characterization in the former lagoon areas, Collection of surface soil samples from suspected waste disposal/storage areas, Collection of surface water and sediment samples from streams and ponds located downgradient from the site, • Collection of any liquids and/or waste material from existing tanks, A survey of private water wells in the vicinity of the site to determine, location, use, and present condition, Rehabilitation of the existing site monitoring wells, Installation of initial ground water monitoring wells for ground water sampling and water level measurements, • Hydraulic conductivity testing of the upper aquifer. Objectives of the Phase II Field Investigation are: • Characterize the horizontal extent of any residual sources or soil contamination identified during the Phase I field . investigation to the extent required for the assessment of remedial alternatives, • Investigate the extent of residual sources and soil contamination which may be present, • Investigate the extent and nature of ground water contamination which may be present, • Gather additional data sufficient to support the assessment and feasibility of any required remedial alternatives. 10 I I I I • g D I I I I I I I I I I I I Phase II Field Investigations will include: Sampling and analysis of ground water from appropriate privaJe wells, Excavation of soil borings in the former lagoon areas with documented residual contamination as needed to define vertical migration, Installation of additional ground water monitoring wells for more detailed assessment of site hydrogeology and the extent of contamination, Hydraulic testing (pumping test) of the site surficial aquifer. , 1.5 PROJECT SCHEDULE The estimated schedule for completion of the RI/FS is presented in Figure 1.2. Time zero of the schedule coincides with EPA approval of the site POP. Implementation of the RI/FS has been divided into discrete tasks to indicate the coordination of parallel and consecutive elements through completion of the project. Descriptions of the tasks are provided in the Macon/Dockery Site Work Plan. Procedures for implementing specific tasks are described in greater detail herein. 1.6 PROJECT ORGANIZATION The overall project management organization for the Macon/Dockery Site RI/FS is shown on Figure 1.3. Overall administrative responsibility for completion of the RI/FS is centered around the SEC project manager. The RI and FS project supervisors will be directly responsible for the coordination and implementation of these respective elements of the project.

The results of this study will be used to evaluate the necessity for further remedial action at this site and to support the selection and design of remedial alternatives if required. If contamination is confirmed, public health impacts will also be evaluated. The FSP for the Macon/Dockery Site provides the framework for the implementation of the ' data gathering tasks associated with the approved Work Plan. The tasks described in· the Work Plan provide the basis for the types of general activities and sampling locations further delineated in this FSP. Based on subsequent site inspections and discussions with EPA Region IV some of the general information presented in the Work Plan has been refined to provide the most appropriate technical methods for developing a consistent and complete RI database. The sampling objectives and sampling locations outlined in the Work Plan provide the basis for the efforts described in the subsequent FSP. As described previously, the sampling efforts and field testing will be conducted in two separate phases. The actual numbers of specific media samples will be dependent on certain site specific conditions such as depth to ground water, depth to target geologic units, the percent recovery obtained from sampling devices, etc. Specific criteria for sample selection and frequency have been included for each sampling method described. Should actual field conditions or observations made during field activities differ from the assumptions of the original Work Plan the RPM will be contacted with this information and 18 I I I I I I I I I I I I I I I I I I I appropriate modifications can be agreed upon before further work proceeds. The number of sampling locations originally proposed in the Work Plan is summarized in Tables 2.1 and 2.2 for the individual phases. Samples collected during the RI will be S(!bjected to field screening and/or laboratory analyses. All laboratory chemical analyses will be conducted by an active participant in the EPA Contract Laboratory Program (CLP). Sample collection procedures and protocols will be in general accordance with EPA's (EPA, 1986) procedu~es manual. Any modifications or changes to the procedures described herein will be documented or in the field log book and will be documented to the EPA RPM. ' 2.1.1 Data Quality Objectives Data Quality Objectives (DOOs) are based on the concept that different data uses may require different data quality. Three levels of analy1ical data quality, as summarized on Table 4-3 of the EPA DOO document (EPA, 1987a), will be generated and utilized during the Macon/Dockery RI. A brief description of each analy1ical level and its respective application is provided below: • Level I (screening): this analy1ical data quality level is acceptable for general site characterization and health and safety monitoring during implementation of field activities. Organic vapor analyzers (OVAs) will be utilized for health and safety monitoring and sample screening during sample collection activities for this project. Level Ill; this analy1ical data quality level employs analy1ical methods o)her than those specified in the CLP (RAS) Routine Analy1ical Services. This level does employ EPA-approved procedures, such as those in SW-846 (EPA, 198Gb). Some Level Ill procedures may be equivalent to CLP MS with the exception of the ex1ensive CLP required documentation. 19 I I I I I I I I I I I I I I I I I I I TABLE 2.1 SUMMARY OF PHASE I RI FIELD ACTIVITIES Activity Quantity Existing Monitoring Wells 3 New Monitoring Wells 4 Surface Soil Samples 26 Source Characterization Samples 12 Test Pits 12 Soil Boring • Surface Water Samples 7 Streambed Sediment Samples 7 Slug Tests 4 Tank Samples •• • Number of locations dependent on analytical results of test pit characterization samples. •• Actual number of locations will be determined by the number of tanks identified, accessibility, and presence of waste material. 20 I I I I I I I I I I I I I I I I I I I TABLE 2.2 SUMMARY OF PHASE II RI FIELD ACTIVITIES Activity New Monitoring Wells New Pumping Test Wells Monitoring Well Soil Boring Samples Private Well Samples Slug Tests Pumping Test Surface Water Samples (if required) Streambed Sediment Samples (if required} Quantity 14 2 12 * 8 1 2 2 * Actual number of locations will be determined by the number of wells identified, their hydrogeologic relationship to the Macon/Dockery site, accessibility, and integrity. 21 I I I I I I I I I I I I I I I I I I I • Level IV (conformational); this analytical data quality level requires full CLP analytical and data validation procedures. This quality of data is suitable for the evaluation and design of remedial alternativ~s and for risk assessment. To meet the objectives. of this RI/FS, samples of surface water, sediment, soil, and ground water subjected to laboratory analysis during this study will be analyzed in accordance with CLP protocols. 2.1.2 RI Sample Handling and Analytical Requirements The RI field investigation will be conducted in two primary phases, and several sub- phases, to allow for adequate evaluation of data collected in each step and, for refinement of proposed sampling locations and analytical parameters. The analytical program proposed for the Macon Dockery site RI field investigation includes ground water, surface water, streambed sediment, and soils analyses. Sample locations and collection procedures for each media are described in Sections 2.3 through 2.7 of this POP. These procedures have been developed based upon EPA (EPA, 1987b, EPA, 1986b) and EPA Region IV (EPA, 1986c) guidance documents. Sample handling and Chain-of-Custody (COC) procedures have also been developed for this project based upon these same guidance documents. These procedures are described in Section 2.12, Sample Chain of Custody. Analytical methods, and preservation, container, and holding time requirements for this project will be in accordance with the appropriate sections of the CLP Inorganic and Organic Statements of Work (EPA, 1987c, and EPA, 1988a, respectively), or SW-846 (EPA, 1986b). These method-specific requirements applicable to this project are described below in Sections 3.2 (Sampling Quality Assurance) and 3.4 (Analytical Procedures). Since all source characterization type samples are being collected in Phase I the Work Plan requires the use of the TCL and TAL parameter lists. To avoid processing 22 I I I I I I I I I I I I I I I I I I Phase II samples for analytical fractions not identified at the site these initial results I will be reviewed prior to Phase II. The results of chemical analyses conducted during the initial.phase of the RI (Phase I) will be used to develop a set of indicator parameters which will be used for I subsequent analyses conducted during the RI. Indicator chemicals will represent the major analytical fractions identified in the Pha~e I source characterization. This list:will be submitted to the EPA RPM an9 finalized prior to subsequent sampling and analyses. Samples which will be used to develop the Macon/Dockery Phase II site-specific list of indicator parameters are: • • Ground water samples (7) collect.ed from existing monitoring wells MW- 1, MW-2, and MW-4, and new wells MW-10, MW-11, MW-12, and MW-19 (Figures 2.1 and 2.2), Soil samples taken from test pi 1 ts excavated in former lagoon areas (Figures 2.1 and 2.2), Surficial soil samples taken from areas of the site suspected of being used for waste storage, ' Surface water and streambed sediment samples collect from potential ' transport pathways at site borders. QC samples will be collected during the entire field sampling program. Field blank, sampler rinsate blanks, trip blanks, and split and duplicate samples will be collected I ' as part of the QC program for this project. A'. discussion of the purpose of these QC I samples and the criteria for their collection is presented in Section 3. 7.1. 23 ..

One existing monitoring well has been designated for use as a background well. Two streambed sediment/surface water sample locations have been designated as background locations. Two soil samples location have been designated as a I background samples for comparison with other soil. samples collected on the ' Macon/Dockery site. Background data collected during the RI will be used in I conjunction with existing site data and available literature to establish contaminant evaluation criteria for the Macon/Dockery site. 2.1.3 Site Security The objectives of site security during the field investigation are as follows: ,· Control access to the site durir;ig the RI I Prevent vandalism and/or theft of equipment. Gates and fences are located at both sides which can be locked to prevent unauthorized entry. One additional lockable gate will be added adjacent to the ' Macon site residence to provide full security. Any persons attempting to enter the site during working hours must be authorized by the on-site coordinator and will be requested to sign in, state his or her pu:rpose, and time of departure. Persons wishing to enter the site during the RI should have the approval of EPA. During non- work hours, the Richmond County Sheriff's: Department will be requested to observe the site during their patrol. At all times during the progress of the work, precautions shall be taken to prevent access to monitoring wells by unauthorized personnel. Temporary measures used to prevent access to incomplete wells which are left unattended due to construction schedules will be documented in the field log book. 26 I I I I I I I I I I I I I I I I I I I 2.2 2.1.4 Potable Water Supply Potable water will be needed during the field investigations for equipment decontamination, grout preparation, and drilling operations. Potable water will be obtained from the nearest treated municipal supply, brought in by tank truck, and stored on-site. Available sampling records will be collected for the water source prior to its use in field activities. If deemed necessary after reviewing these records, SEC will collect one sample for chemical analys~s prior to each of the RI phases. 2.1.5 Health and Safety Procedures Health and safety procedures which will be implemented during the scheduled field activities identified in this POP are described in Section 4; Macon/Dockery Site RI/FS Health and Safety Plan. GEOPHYSICAL SURVEY 2.2.1 Overview I . A geophysical survey will be conducted to: assist in identifying areas where tanks, drums, other metallic vessels, or other areas of metallic debris may have been buried. The surface geophysical survey will be conducted using electromagnetic (EM) instrumentation, as described in EPA {198,0, Section 8.4.2.1. The EM method has several advantages over other available geophysical techniques. Continuous readings ' can be made along survey lines so that t~e potential for detection of subsurface anomalies is increased. Also the equipment provides excellent flexibility to adjust ! survey lines for physical obstructions and interferences. A Geonics Model EM-31 will be employed for the purposes of this st1.1dy: The EM-31 generally measures the 27 I I I I I I I I I I I I I I I I I I I quadrature-phase component of an induced magnetic field. The deductibility of large metal objects by the EM-31 is enhanced by-measuring the in-phase component of the induced magnetic field instead of the quadrature-phase component. 2.2.2 Survey Procedure The EM-31 will be operated as follows: 1. The Mode switch will be placed in the COMP position instead of the OPER position. 2. The COARSE and FINE compensation controls are adjusted so that a meter deflection of 20% of full scale is obtained. This procedure, adjusting to 20% I of full scale rather than to zero, allows for negative readings and sudden changes in reference levels due to a bump or other sudden movement. 3. It is recommended for Step #2 above that the Range be set at the 30 mmho/m range. More or less sensitive positions may be employed. 4. The EM-31 is operated continuously as the operator moves from one measuring station to the next. The EM-31 survey will be conducted in areas of the Macon/Doc:,ery site where waste materials were likely stored or disposed. The survey will be initiated by establishing a baseline along one perimeter of the site with stakes set at a 50-foot spacing. At the first baseline position, the EM-31 will be turned go· from the baseline to establish the first survey line. Although a 50-foot grid spacing will be employed as a guideline for the survey, more dense survey transects will be completed in highly suspect areas (Figures 2.3 and 2.4). 28 liiil LEGEND ~ Woods Line ~ L~goon Road Approximate Area of EM-31 Survey .. -liiil llill liiiiil lill -lliil iiiil lilll■liSIRRINE 1■•■11 ENVIRONMENTAL llll CONSULTANTS f.reenvl lie, South Corol!M DRAWING-TITLE EM-31 Survey Area Macon Site SEC DRAWING MJMBER Figure 2.3 - "" () iilil 0 SCALE ,:,o DO iilil liill -iiil liilll - LEGEND ~ Wagg~ ~ine 0 Lagoon Road (2G3 Appro1drnate Aroa at EM-31 Survey Coo,, i~hl ©-----s, ..... i. • .,,-,,.1 c .... 1,.,.,., 1,. 111••SIRRINE II■■ ENVIRONMENTAL llll■coNsuLTANTs Greenvl Ile, South Co..-ollno DRAWING TITLE EM-31 Survey Area Dockery Site SEC DRA•ING NUMBER Figure 2.4 liiiiiil I I I I I I I I I I I I I I I I I I I Transect distance, bearing, and instrument readings will be recorded for each transect line. At the completion of each transect, survey results will be reviewed to determine the necessity of additional EM-31 coverage, along and/or adjacent to the completed transect. Careful attention will be afforded. to the presence and quantity of metallic surface debris located along the transect line. It is anticipated that some interference of the survey will be caused by the large amount of metallic surface debris located at the site. The presence of surface metallic debris will be considered when analyzing anomalous EM readings. Neither the EM-31 nor the metal detector are required to contact the ground surface during operation. Therefore, no field decontamination procedures are required. If it is necessary to place the instrument(s) on the ground, the instrument(s) will be placed on clean plastic sheeting. 2.2.3 Quality Control for Geophysical Survey All EM field measurements will be recorded in the field log book. The survey results will be presented based on the following information: Survey run number Bearing Distance EM reading All survey lines will be referenced to established benchmarks located on the base map. 31 I I I I I I I I I I I I I I I I I I I Prior to the start of each day of the EM survey, a background survey will be I conducted at a location removed from the potential source areas of the site to establish a baseline. A fixed transect line of approximately 100-feet will be surveyed. This same line will be surveyed at the erid of each survey day to provide quality control of the instrument's performance. In addition, during each day of the survey, 5% of the surveyed area will be duplicated to provide additional quality control of the EM survey equipment. 2.3 SOIL SAMPLING PROGRAM 2.3.1 Surface Soil Sampling I Surface soil samples will be collected fr?mi various locations at the Macon/Dockery site where historical aerial photographs indicate that drums have been stored. Composite soil samples will be collected. from suspect areas identified on the photographs and from the site reconnaissance. Surface soil samples will be collected from the general locations specified on Figures 2.5 and 2.6, as outlined in Section I 2.2.2, Soil Sampling, of the Macon/Dockery Site Work Plan, March 1989. 2.3.2 Surface Soil Sampling Procedures Twenty-six surface soil samples will be collected from designated suspect areas at the Macon/Dockery site. Exact sample locations will correspond to the most visibly • I I contaminated surface soils observed in that area. Most of the soil sampling locations designated in the Work Plan are in areas where a vegetative turf is established. At I these locations a clean stainless steel trowel will be used to carefully remove the turf. When the clean soil surface is exposed, a hole will be advanced to a depth of two feet using a stainless steel hand auger. All 2uger cuttings will be collected . and carefully placed in a glass or Teflon-coate:d siainless steel pan to be mixed (or composited) prior to filling the sample containers. 32 I!!!!!!! == LEGEND ~ Woods Line ~ Lagoon Road + Soll Sample Localion Suspect Area liiiil -.. .. -iiiiil ~ -••.-----z - ••1SIRRINE llll■ ENVIRONMENTAL II■ CONSULTANTS Greenvl lie, South Carolln<1 DRAWING TITLE Surface Soll Sample Location Map Macon Site SEC DRAWING MJWBER Figure 2.5 iiiiil ----II!!!!!!! l!!!!!!I liiiiil liiiil liiill SCALE 0 150 ~ -.. ..

A i stainless steel spoon will be used for mixing.1 The soil will be scraped from the sides, corners, and bottom of the pan, rolled to the middle of the pan, arid gently mixed. The sample will then be quartered and separated into the four corners of the mixing pan. When the soil has been thoroughly mixed and is as homogeneous as possible it will be divided and placed in the appropri~te sample containers (Section 3.2). Each sample container will be carefully filled as full as possible to eliminate free air space. The container may be gently tapped': during the procedure to assist in filling each jar completely. Surface soil samples collected during Phase I of the RI will be analyzed for the TAL parameters. 2.3.3 Test Pits/Subsurface Soil Sampling -Potential Source Areas Source area characterization will be conduct~d in several former lagoon areas in, an effort to detect any residual source material. During the early field effort, the location of the former lagoons will be delineated based upon available aerial photographs. Subsurface soil samples will be collected using one or a combination of two methods. Both test pits and soil borings will be utilized, as appropriate, to characterize the quality of soil in potential source areas. Test pits will serve to characterize the levels of contamination in the upper 1 O feet. Where :significant contamination is confirmed, I soil borings will then be utilized to define the _vertical distribution at locations below 10 feet. Test pits (EPA, 1987c, section 8.2) will:be excavated in these areas to enable both visual observation and sample collection of the subsurface material. Test pits proposed for Phase I are particularly applicable to the Macon/Dockery RI due to the absence of well-defined waste management area boundaries. The use of soil borings only would increase the potential for missing ,the actual waste management areas. Soil borings will be utilized in the Phase II inv~stigation to assess the vertical extent 35 I I I I I I I I I I I I I I I m 0 D m contaminated areas where residual contamination is confirmed. Subsurface soils I samples will be collected from the locations specified on Figures 2.5 and 2.6. ' : ' 2.3.4 Test Pit Excavation and Sampling Procedures : Test pits will be excavated to provide initi~I source characterization in and around the former lagoon areas. The objective ot' source characterization is to determine I the potential presence and concentrations of residual contaminants, if any, at each ' of the designated lagoon areas. This information will be used primarily to evaluate alternatives for source control. Test pits' will allow sampling and direct visual characterization of any residual wastes which may be present and assessment of I former lagoon conditions. i A total of 12 test pits will be excavated during the RI (Figures 2.1 and 2.2). The I proposed test pits will be excavated during Phase I to collect samples which will be I used to develop the site-specific indicator parameter list. Additional test pits may be excavated during Phase II based upon the electromagnetic survey results. One composite soil sample will be selected for TCLJTAL analysis from each test pit. The test pits will be excavated with a standard backhoe in accordance with EPA Superfund field investigation guidelines (EPA, 1987b). The final orientations and dimensions of test pits will be determined in t.he field based on observed conditions. Minimum test pit dimensions will be approximately 12 feet x 4 feet x 10 feet (length X width X depth). I Four grab samples will be collected from the natural soils excavated from each test pit. For sample parameters other than volatile organics, the grab samples from each test pit will be combined in the field by mixing in a glass or stainless steel pan to form one composite sample from each test pit for analysis. The I 36 I I I I I I I I I I I I I I a D I grab samples will be combined by mixing with a stainless steel spoon as described in Section 4.6.3.3.4 of the Region IV SOPQAM (EPA, 1986c). A discrete volatile organic sample will be collected from each test pit prior to the other samples to minimize volatilization of organics. All rocks, twigs,· or foreign ' debris will be removed from the sample prior to homogenizing. ' All samples collected from the test pits shall be selected from the most heavily contaminated soils exposed in each test pit, based on the results of screening ~ith . ' ' an OVA and visual assessment. The samples will be carefully selected from the material removed by the backhoe to assure t~at material which has come into contact with the backhoe bucket is not included. In:addition, soil selected for sampling· will be trimmed with a stainless steel or Teflon s9oop prior to final sample collection. A separate stainless steel scoop will then be used to collect the sample. Soil samples collected from the test pits excavated during Phase I will be subjected to TCL/TAL analyses. Each test pit will be described in the field log book. Data recorded will include: ' • • • • Date of excavation Approximate surface elevation Total depth of excavation Dimensions of pit Method of sample acquisition Type and size of samples • Soil and lithologic descriptions Ground water occurrence Organic vapor readings ' • Other pertinent information, such as waste material encountered I 37 I I I I I I I I I I I I I n D I I I Final test pit lithologic logs will be typed on the form included as Figure 2.7. ' After logging, each test pit will be pho)ographed and backfilled. The approximate location and orientation of each test pit will be plotted on the field plan and the location will be staked for future reference. ' 2.3.5 Soil Boring Sc1mpling -Potential Source Areas Soil borings will be conducted to characterize potential source areas vertically ' if necessary based upon the results of the soil samples collected from test pits. For test pit locations in Phase I that do not present a risk to human health and ' the environment, no further characterization will be conducted. If contamination of concern is confirmed in the soil samples, collected from a test pit, a soil boring will be conducted immediately adjacent to the pit. The boring will be i sampled at five-foot intervals from the bottom; of the test pit to the water table. All samples will be transported to the analytical laboratory for potential analyses. Analyses of the samples will be conducted of each sample in vertical succession until two consecutive samples are determined to be below or near the quantitation limit. Based upon the presence of waste material arid a underlying synthetic liner in lagoon 10, soil borings through the lagoon may not be advisable. Following the initial test pit excavation in lagoon 10, an evaluation will:be made regarding the necessity and appropriate methods for further investigation ~eneath the lagoon liner. 38 I I I I I I I I I I I I I I n 0 I SIRRINE ENVIRONMENTAL CONSUL TAN TS PROJECT: CLIENT: CONTRACTOR: EQUIPMENT USED: SAMPLE DEPTH NOJ STllATA (FT) DEPTH CHANGE RANGE (FT) - - -- L-- L... - ~ - ~ - L - GROUND WATER DATE TIME• NOT ENCOUNTERED T FIGUR.E 2.7 ' TEST PIT REP'ORT TEST PIT NO. i I JOB NO: LOCATION: ' ELEVATION: DATE START: DATE ANISH: ' LOGGED BY: I ' FIELD CLASSIFICATION· REMARKS ' ' I , ' : ' I : I ' I ' I I ' ' ' ' I ' i AS1MCOMPONENT%.

Generally, the sampling 1procedure to be used to collect subsurface soil samples from borings is in accordance with ASTM D1587-74 I and will be performed as follows: A borehole will be advanced using hollow stem augers to a depth of fifteen feet. At this point, a stainless steel split spoon will b~ driven into the undisturbed soil below the augers. These auger advancement and stainless steel split spoon sampling techniques will be performed as described above at five-foot depth intervals from ,the I bottom of the test pit to the top of the water table. ' Immediately after removing the stainless steel ~plit spoon from the ground, the sample will be withdrawn from the spoon using a stainless steel spoon. A portion of the ' sample will be collected immediately for volarne organic analyses. As the remainder of the sample is removed from the spoon, it will be placed in a glass or Teflon-coated stainless steel pan to be mixed prior ·to filling I the sample containers. Sample mixing will be performed immediately, after removal from the stainless steel I split spoon. A stainless steel spoon will be us¢d for mixing. The soil will be scraped I ' from the sides, corners, and bottom of the p~n, rolled to the middle of the pan and gently mixed. The sample will then be quartered and separated into the four corners : of the mixing pan. Each quarter of the sample, will be mixed individually following the I same procedures outlined above. Each quarter will then be rolled into the center of the mixing pan; and gently mixed again. 40 I I I I I I I I I I I I 0 D E I I I I When the soil sample has been thoroughly mixed and is as homogeneous as possible, it will be divided and placed in: the appropriate sampl~ containers as described in Section 3.2. Each sample container will be carefully. filled as full as I I possible to eliminate free air space. The container may be gently tapped during this procedure to assist in filling each jar completely. 2.3.7 Soil Boring Sampling -Monitoring WeHs During the installation of ground water monitoring wells in Phase II, subsurface soils i samples will be collected for chemical analys,es. Soil samples will be collected from the boreholes of Phase II monitoring wells MW-2A, MW-6, MW-7, MW-BA, MW-9, MW- 11A, MW-13A, MW-14, MW-15, MW-16, MW-17, and 18 (Figures 2.1 and 2.2). 2.3.8 Soil Boring Sampling Procedures -Monitoring Wells ' Subsurface soil samplers will be collected usi~g stainless steel split spoon samplers at five-foot intervals. The soil borings, upon completion, will be used for the installation of Phase II ground water monitoring wells. Prior to sampling any vegetative turf will be carefully removed using \a stainless steel trowel. When a clean soil surface is exposed, a stainless steel split ~peon will be driven 24-inches into the ground using the drill rig. Soil sampling will be conducted at five-foot intervals in the Phase II monitoring well test borings. The samples will be collected at alternating five-foot intervals for I chemical analyses and lithologic description. T~is sampling sequence will extend from the land surface to the water table. Samples 'tor lithologic analyses will continue to ' the depth of the boring at five-foot intervals. This sampling sequence is necessary due to the lack of sufficient sample volume 'trom a split spoon within a five-foot interval for complete TCL/TAL analyses. Due to the non-cohesive nature of tl:le 41 I I I I I I I m I I I sediments expected at the Macon-Dockery ·site, sample recovery may become an ' ' additional volume limiting problem. Further, these borings are located outside of the potential source areas, therefore, significant residual source material in the unsaturated ' I ' soils is unlikely. ' Following collection, all samples will be transported to the laboratory for processing. I Complete analysis will be conducted for the two initial samples from a particular location. If results of these samples indicate that parameter concentrations are below ' or slightly above the quantitation limit, the remainder of samples from that boring will not be processed. If only discrete analyti~al fractions are found, these will' be evaluated until the criteria is met. If the res\Jlts of these samples do not meet this criteria, additional samples will be processed sequentially until two consecutive samples are below or slightly above the quahtitation limit. Immediately after removing the stainless steef split spoon from the ground, the I sample will be withdrawn from the spoon using a stainless steel spoon. A portion of the sample will be collected immediately for volatile organic analyses. As the remainder of the sample is removed fr.om the spoon it will be placed in ' a glass or Teflon-coated stainless steel pan to be mixed prior to filling the sample containers. I Sample mixing will be performed immediately after removal from the stainless steel split spoon. A stainless steel spoon will be used for mixing. The soil will be scraped from the sides, corners, and bottom of the pan, rolled to the middle of the pan and ' ' gently mixed. The sample will then be quartered and separated into the four corners ' ' of the mixing pan. Each quarter of the sample will be mixed individually following the ' same procedures outlined above. When the soil sample has been thoroughly mixed and is as homogenous as possible, it will be 1divided and placed in the appropri~te sample containers as described in Section 3.2. 42 I I I I I I I I I I I I I I I I I I I Each sample container will be carefully filled as full as possible to eliminate free air space.

Nine surface water, sample locations have been identified I I ; ' in the vicinity of the site. A total of seven surface ,water samples will be collected during I Phase I of the RI. Two additional locations have been selected for sample collection during I Phase II if necessary based upon the results of Phase I samples. Sample locations are shown on Figure 2.8. To prevent sample dilution and elevated levels of suspended solids, I no surface water samples will be collected during oj immediately after any major rain event and always preceding collection of the streambed sediment sample. Surface water samples I will be analyzed for TCL/T AL parameters. Surface: water samples will be collected either directly with the sample container or with a dipper1 constructed of inert material such; as stainless steel, Teflon, or glass. Each surface water sample will be divided into sam'ple containers required for the different methods of analysis. The containers for volatiles will be completely filled such that a convex meniscus is formed allowing no headspace in the vial. If no surface water is present at a given locc1tion only the sediment sample will be collected. 2.5.1 Stream Sampling Procedures I Prior to obtaining a surface water sample from· a stream for semi-volatiles, pesticides, I I and inorganics, a dipper will be attached, if necessary, to a long pole to allow access I to any point in the stream. The dipper will initially be flushed thoroughly with water from the stream. To collect the sample, the :dipper device will be submersed with ' minimal surface disturbance. When the sam~le has been collected in the dipper, it 54 I I I I I I I I I I I I I g 0 I will be gently transferred to the sample containers. To obtain a surface water sample from a stream for volatile organics, the sample will be collected directly in the sample container. I 2.5.2 Pond Sampling Procedure I An alternate procedure will be used to sample the small pond to account for possible I contaminant stratification. A vertical composite will be obtained from the center of the . ' pond by withdrawing discrete water sampl~,s from a deep, midpoint, and shallow water depth and compositing into one sample. The vertical composite will be mixed by gently transferring the sample to an open glass, Teflon, or stainless steel container. ' Sample containers for semi-volatiles, pesticides, and inorganics will then be filled I directly from the open mixing container using care to avoid agitation of the sample. I The sample for volatile organics will be directly collected from the midpoint location and not composited. The pond samples will be collected using a: Bacon Bomb Sampler. This stainless steel sampling device allows collection of water samples at discrete intervals. 2.5.3 Sampling Personnel and Equipment The following field personnel will direct and complete surface water sampling activi!ies as detailed above: On-site Coordinator/Field Hydrogeologist • Field/Office liaison • • Confirmation of sampling location$ Overall technical oversight 55 I I I I I I I I I I I I I I I I I I I Technician • Sample collection • Assistance with record keeping Sample packaging and shipment ; I The equipment required for the described tasks includes: ! • • • • • • • Bacon Bomb sampler Camera Field log book Thermometer Specific Conductivity meter Stainless steel or Teflon dipper Sample containers and labels Coolers with ice packs Sample document control forms Decontamination equipment Health and Safety equipment 2.5.4 Decontamination for Surface Water Sampling Equipment I Decontamination of surface water sampling e9uipment will be accomplished by using the following procedure: I 1.

The sampling program will consist of sampling existing and newly constructed monitoring wells during Phase I of the investigation and sampling all wells constructed during Phase II of the investigation as outlined in Section , 2 of the Work Plan. The locations of existing and; planned wells are presented in Figures ' 2.1 and 2.2. The sampling program will include collection of samples for laboratory analysis, field analysis of pH, specific conductance,· and temperature, and ground water ' level measurements. Following the private well survey conducted during Phase I of the RI, appropriate private ' wells in the vicinity of the Macon/Dockery site will be selected for sampling. These well will ' be sampled in accordance with procedures outlined in EPA (1986c) and chemical analyses conducted for appropriate site-related indicator parameters. 2.8.1 Ground Water Sampling Procedures One set of ground water samples will be collected from the existing wells and new ' wells MW-10, MW-11, MW-12, and MW-19 during Phase I.

Well Evacuation Each well will be purged prior to sample collection to remove any stagnant water from the well, thereby ensuring that the saniples collected are representative of the ' . . water quality surrounding each well. Prior to well evacuation or sample collection, the ground water depth is determined using an electronic water level meter as ' described in Sectior.i 2.8.8. Following each use, the instrument is cleaned according to the field cleaning procedure described in :Section 2.8.6. For wells that recover quickly, three to five volumes of water will be removed. ' Specific conductance, pH, and water temperature will be measured periodically during ' well evacuation. Wells that can be evacuated to dryness with less than five well ,. ' ' volumes being removed will be sampled as ,soon as the well has recovered enough to yield sufficient volume for a sample. Well purging will be accomplished using Teflon bailers with Teflon-coated stainless steel leaders. Only the bailer and leader will be allowed to contact the water colcimn. Only new polypropylene rope will be used: at each sample location. Care will be taken to ensure that the rope does ont cor;itact the ground during well evacuation or sample collection. Purging techniques will be in accordance with procedures ' described in Section 4.7.5.3 of the EPA Region IV SOPQAM (April, 1986). The volume of water to be evacuated is calcula\ed using the following equation: where: 1r = 3.14159 r = radius of well casing 75 I I I I I I I I I I I I I I I I I I I h = height of water column in well (Tbtal well depth -depth to ground water ' prior to purging.)

Wrap equipment completely with aluminum foil to prevent contamination during I I storage or transport to and from the fieldl and between sampling locations. Water rinsate from the decontamination process will be allowed to percolate into the I I soil in confined, designated areas. These sites will be located in areas where near i surface soils are expected to be contaminat~d. The boundaries of these sites will be 77 I I I I I I I I I I I I I I I I I I I surveyed and included on the site plan. Dilute acid rinsate will be further diluted with tap water prior to disposal. 2.8.7 Quality Control for Ground Water Sampling QC for ground water sampling consists of traceable documentation of sample I collection activities, proper field preservation t!lchniques, and measurement of sample handling effectivenel5S using appropriate blank samples. Ground water sample collection activities will lbe traceable through a permanent field ' log book maintained by field personnel. The field log will include the information I given on the sample label as well as the sampling equipment used. All ground water samples will be labeled at the time of sampling in accordance with Section 2_.11. ' Field preservation of ground water samples being sent to the analytical laboratory will I comply with the requirements given in Table, 3.1. Necessary preservatives will be added and samples will be cooled immediately after collection. Shipping containers will be prepJred for transportation to the labora,tory I in accordance with Section 2.12, Sample COC. Ground water samples will be placed in clean glass jars to be field analyzed for pH, ' specific conductance, and temperature. Field calibration of analytical equipment will be in accordance with Section 3.5. Laboratory accuracy and precision will be verified through the use of MS and MSD samples in accordance with standard CLP lprotocols. Additional QC samples', as I describe in Section 3.7, will be collected as appropriate during the ground water sampling investigation. 78 I I I I I I I I I I I I I I I I I I 2.8.8 Ground Water Level Measurement ' ' Water level measurements will be taken frorl) all monitoring wells at the site during : the RI. Water level measurements will be ,made on a bi-monthly basis or niore I frequently during the RI to monitor water level fluctuations. Water level measurements will be taken from all monitoring wells at the ~ite on the same day at least two ti~es during the RI to provide two complete sets oi comparable measurements. Surveyed I . elevations will be established at each well to determine water level elevations. These water level measurements will be us~d to caldulate hydraulic gradients and determine ' I' directions of ground water flow at the site. 2.8.8.1 Equipment and Procedures All water level measurements will be made using an electronic water level I meter. The water levels will be measured by slowly lowering the instrument probe into the well. When the probe reaches the water surface, the circuit i is completed and a buzzer is activated. The distance from the top of the well ' casing to the water level is then measured and recorded. The water level ' indicator cable is calibrated in increments 'of 0.05 feet. Water levels will be estimated to nearest 0.01 feet. i All water level measurements will be recorded in the field log book including: date and time of measurement, description:of measuring point and the name of I the individual making the measurement. 1When the well cap is removed, an I • OVA will be used to screen the air space: immediately above the well casing. The level of vapors detected and any odors noted will also be recorded. I 79 I I I I I I I I I I I A history of all ground water level measurements taken during the RI will be maintained for each well on a Ground Water Level Monitoring Report (Figure I 2.12). Complete sets of water level measurements taken on the· same day ' will be recorded on the Water Level Summary Report (Figure 2.13). 2.8.8.2 Equipment Decontamination All equipment will be decontaminated between wells in accordance with the ' : procedures described in Section 2.8.6. 2.8.9 Total Well Depth Measurement The total depth of all monitoring wells will be measured prior to initiating well I evacuation. The well depth is determined by; slowly lowering a heavy stainless steel i weight attached to a fiberglass tape measure into the well. When the bottom of! the well is encountered, the tape will be raised slightly and slowly lowered until the weight is resting on the bottom of the well and the tape remains taut. The depth of the well is then read directly from the tape. The length of the height will be added to the I depth read from the tape and recorded in the field log book. Both the tape measure and the stainless steel weight will be decontaminated between wells in accordance I with the procedures described in Section 2.8.6. I 2.9 HYDRAULIC TESTING I I I I I I Slug tests will be performed during Phase I and II of the RI to determine I representative hydraulic conductivity values for the sites. 80 I I I I I I I I I I I I I I I I I I I ' FIGURE 2.12 SIRRINE I !

After water levels have stabilized from the pre-test, at least 12 hours of water level data will be collected immediately prior to conducting the test. The pumping test will be condudted for a minimum of 24 hours at a ! constant pumping rate. Recovery will be mor;iitored for a minimum of 12 hours after pumping has ceased. Ground water, pH, specific conductivity, and discharge rate will be monitored throughout the test. The pumping test will be conducted in I accordance with procedures described in :Groundwater and Wells (Johnson Division, I 1986) and Groundwater Pumping Tests (Walton, 1987). The pumping test location will be selected after chemical analyses of ground water : ' samples have been completed. The test location will be selected to minimize potential impact to existing ground water conditions. If analyses indicate that the ground water contains hazardous constituents above action levels at the test location, water from I ' . I the pumping test will be discharged according to state requirements or containerized ! for proper disposal. 85 I I I I I I I I I I I I I I I I I I I Appropriate data analysis methodology will b:e selected based on t~e characteristics of the drawdown curve. Porous media analyses, based on Thei~ (1935), will be performed if appropriate. 2.9.5 Equipment Decontamination I Equipment will be ·decontaminated in accordance with procedures described in , I Section 2.8.6. 2.10 SOIL GAS SURVEY ' Following completion of Phase I of the RI, an evaluation will be made to determine· the appropriateness of a soil gas survey. If it is determined that a soil gas survey is necessary, ' a modification to the POP will be submitted to the RPM for approval. This modification will I present detailed procedures for conducting a ~oil gas survey at the Macon/Dockery site. 2.11 SAMPLE IDENTIFICATION Prior to collecting each sample, the sample cont1iners will be labeled with the following information: 1 • Date and time of sample collection • Sample identification code • Name of person who collected sample Type of preservative added to sample • Parameters to be analyzed 86 I I I I I I I I I I I I I I I I I I I Other media specific information, such as sampling interval, may be added. The sample identification code will consist of the SEC job identification number, a sample media code, a sample location number, and a sample replicate number. The format for the sample identification number is as follows: 9168-SW-2-1 where: 9168 = Macon/D'ockery job identjfication number SW = sample media code 2 = sample location number 1 = sample replicate number Sample media codes are SW for surface water samples, MW for ground water samples, SEO for sediment samples, SL for soil samples, and W for waste samples. The sample ' location number on the label will correspond to the: sample location numbers assigned on the field site map. ' ' If it is determined during the field sampling program that additional samples are needed in locations other than those designated in the POP ihe following procedure will apply: ' I 1. Collect sample in accordance with the apl?ropriate media sampling procedure in ' the POP. 2. Assign a sample identification code using the next highest sample location number. 3. Mark location where sample was collected with a stake and write the sample identification code on the stake. 87 I I I I I I I I I I I I I I I I I I I ' 4.

Therefore, COC procedures will be instituted and followed throughout the RI. ' I I COC procedures include field custody, laboratory custody and evidence files. The National I Enforcement Investigation Center (NEIC) of the EPA defines custody of evidence in the following ways: • In actual physical possession • In view after being in physical possessionl • In a locked repository • In a secure, restricted area It is necessary to establish documentation to trace sample possession from the time of collection until disposal. The following list outlines field custody requirements: I I ' ' • As few people as possible shall handle sample(s). ' • Sampler shall be responsible for the care and custody of the samples until they are transferred or dispatched properly. Samples shall be stored by those individuals or facilities designated on the COC form. The following methodologies will be used to ensure pr6per transfer documentation: ' Samples shall be accompanied by a COC record at all times. 88 I I I I I I I I I I I I I I I I I I I • Samples shall be packed properly for shipment so that bottles will not dislodge I • and/or break during shipment.

The mode of travel must be I such that the sample is not altered physically, chemically or biologically. The travel time to the laboratory must not interfere I with the sample holding time. The COC must also be maintained during the transportation I process. When sent by common carrier, the packaging, labeling and shipping of I hazardous waste and substances is regulated by th'e U.S. Department of Transportation (DOT) under CFR 49 Parts 171 and 173. Samples obtained at uncontrolled hazardous waste sites are classified as either environmental samples or hazardous samples. Environmental samples are those which contain low levels of contaminants and require implementation of limited precautionary 92 I I procedures. Samples at the Macon/Dockery Site are tentatively being considered I I I I I I I I g I I I I m g I environmental samples. Hazardous dangerous levels of contaminants i.e. samples are I those which could possibly contain ' ' Hazardous samples must be packaged and label_ed ' according to procedures specified by the U.S. Dot or the state DOT, whichever is more stringent. Samples collected at the site will be immediately placed in the sample cooler. The sealed and labeled container will be placed insi~e a secure ice chest and packed to pr~vent breakage. Once the cooler is filled with samples, it will be closed and securely positioned in an SEC sampling vehicle or other secure storage facility until the completion of the day's I sampling activities. The following protocol will be followed for packaging of samples: I Only waterproof metal or equivalent strength plastic ice chests and coolers will :be used. Following the completion of the sample label and tag, the sample will be carefl:Jlly I placed or poured into the container in the field. The sample tag will then be attached to the container. 1 • The labels will be permanently affixed to each container. All labels will be completed with an indelible pen. I A custody seal will be placed on the samp,le container. The volume level will be marked on each bottle with a grease pencil. I • Strapping tape will be placed around the lid: of all sample bottles except for volatile ' organic samples. 93 I I I I I I I I I I I • All bottles will be placed upright in the cooler in such a way that they do not touch ' and will not touch during shipment. • Additional inert packing material will be placed in the cooler to partially cover the sample bottles. Ice or freeze packs will be placed around, among, and on top of the sample bottles. • Each cooler will be filled with additional cushioning materials to prevent movement of samples during shipment. ' I • The COC record will be placed in a waterproof plastic bag and taped to the inside lid of the cooler. If the cooler is equipped with a drain plug: it will be taped shut. I The lid will be secured with strapping tape at a minimum of two locations. No I labels will be covered. A custody seal will be placed around the secured coo_ler. The completed shipping label will be attached to the top of the cooler. I ' I ' "This Side Up" labels will be placed on the ~ides of the cooler, and "Fragile" labels will be placed on two sides. ' • Numbered and signed custody seals will be placed on the front right and back : ' left of each cooler. These seals will be covered with clear tape. ' • The weight limit of the shipper will be maintained. 94 I I I I I m D 0 D 0 D I I I I ! I As soon as field personnel are ready to transport samples from the field to the laboratory, they will notify the laboratory by telephone of the shipment. If the samples, are transported ' by field personnel, the estimated time of arrival at the laboratory will be given. If the samples are shipped by commercial carrier, the· laboratory will be telephoned as soon as the shipping containers are consigned to the shipper. Figure 2.15 contains the information I that must be provided to the laboratory. A blank ;of this form will be completed at the laboratory during the telephone conversation. ' The final step in providing information to the laboratory is shown on Figure 2.16. The Request for Analysis form will be completed by the ,field personnel and included with the COC record. It is imperative that the Request fo~ Analysis form be provided so that ' analy1ical requirements are defined and sample holding times are not exceeded. It is I anticipated that all samples will be shipped from the site via Federal Express. 95 I I I I m a I D 0 D I D u m I • I I I FIGURE 2.15: SHIPMENT INFORMATION ' I (Field to Lab by Telephone) Date of Shipment: __________________ _ Laboratory Destination: --------'----------- Laboratory Project Contact: __ ----,---~---------- (Name) (Telephone Number) Number Containers Shipped:------'----- Mode of Shipment: ____________ _ Shipment Number(s): -------~---- Time of Shipment: --------~---- Date/Time of Shipping Info Release to Lab: ----,----------- Signature of Releaser: ------------------ NOTE: PROVIDE THIS INFORMATION,TO RECEIVING LABORATORY AS SOON AS POSSIBLE AFTER SAMPLES ARE SHIPPED. 1 I ------------------·-FIGURE 2.16 11111~!~~~~~ REQUEST FOR ANALYSIS (This form must accompany samples - Do Not send under separate cover) Post Office Box 24000 Greenville; South Carolina 29616 PROJECT NAME DATE SAMPLES SHIPPED PRO.MGR.
