(ETG) has received a contract from the State of North Carolina to prepare the Phase III final design report and develop a set of final plans and specifications for the detoxification of the Warren County PCB Landfill (Site). The North Carolina General Assembly has passed a bill requiring the utilization of Base-Catalyzed Decomposition (BCD) technology for detoxification of the landfill. The bill also specifies the detoxification treatment standard for residual concentrations of contaminants remaining in the soil shall be 200 ppb for PCBs and 200 ppt TEQ for dioxin/furans. Remedial actions at the landfill consist of detoxification of approximately 60,000 tons of materials (soil, sludge, kiln dust, etc.) contaminated with PCBs. The detoxified materials will be placed on-site after analytical testing has confirmed that the material has met the treatment standards established in the legislation for the project. The purpose of this Performance Demonstration Plan (PDP) is to establish that the solid and liquid phase BCD systems. while operating at maximum throughput, will meet material treatment standards and North Carolina air regulations and to obtain an operating permit from Toxic Substance Control Act (TSCA). The Contractor will develop a PDP and submitted for the review and approval of NCDENR, Environmental Protection Agency (EPA), and other regulating bodies as dictated by NCDENR. This PDP has been developed to meet the substantive requirements of TSCA, but may not meet all the requirements for a TSCA permit demonstration plan. This PDP describes monitoring and testing that will be conducted to verify full-scale system performance. ETG Environmental, lnc./BF A Environmental Consultants Final March 2000 Performance Demonstration Plan Warren County PCB Landfill • 2.0 DESCRIPTION OF THE BASE-CATALYZED DECOMPOSITION (BCD) SYSTEM The PCB landfill detoxification project combines the use of thermal desorption with solid and liquid phase BCD technology to completely dechlorinate contaminated material. The BCD detoxification system will include the following major process systems: 1) One continuous solid phase BCD/thermal desorption unit (CBCD), 2) One batch vacuum solid phase BCD/thermal desorption unit (BBCD), 3) Two air pollution control systems or vapor recovery systems (YRS), one each for the CBCD (CBCD-VRS) and BBCD (BBCD-VRS), and 4) One process condensate separation and aqueous phase treatment system (PCSAPT), and 5) One liquid phase BCD detoxification system (LBCD). In addition to the five major BCD process systems listed above. are the following systems: I) Contaminated material preparation system. This system prepares material to feed into the CBCD and BBCD system by removing large debris and mixing solid phase BCD additives into the contaminated soils. 2) Storm water/decontamination water treatment system. There will be requirements for a separate treatment system to treat storm water run-off from the contaminated areas of the landfill, as well as decontamination water generated on-site. The BCD process will· be designed to utilize the treated process condensate to cool and rehydrate the treated soils. The Site Operation Work Plan (SOWP) will incorporate. to the extent possible, utilization of the treated storm water/decontamination water for dust control and for use in the BCD process. The following sections describe each process system. The CBCD-VRS and BBCD-VRS descriptions are contained in the sections describing the CBCD and BBCD systems of equipment. The stormwater/decontamination treatment system is technically not a part of the BCD system and is described in Section 6 of this PDP. 2.1 Contaminated Material Preparation Area Drawing PFD-201 depicts the Material Preparation Process Flow. Contaminated materials from the landfill will be excavated and transported to the material staging area. A certified scale will be located between the material staging area and the material preparation area to determine the actual weight of material processed. The material will be screened utilizing a 2-inch by 2-inch screen. The oversize material will be stockpiled for further processing, which may include, but not be limited to, reprocessing, decontamination and/or disposal. The handling of oversize debris will be consistent with requirements set forth by TSCA. ETG Environmental. Inc./BF A Environmental Consultants 2 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill • The screened material will be fed into the hopper of the contaminated material pug mill plant, and conveyed to a pug mill mixer. The conveyor will be equipped with a magnet to remove metallic debris, as well as a weigh belt scale to determine the feed rate of material to the pug mill. Solid phase BCD reagents will be stored in a silo and fed into the pug mill at a set proportion (2 % to 5% weight/weight) to the quantity of contaminated material being fed to the pug mill. A radial stacker will stockpile the blended material. The material preparation system will be designed to process a minimum of 100 tons per hour of contaminated material. 2.2 Continuous Solid Phase BCDffhermal Desorption Unit (CBCD) Drawing PFD-202 depicts the CBCD Process Flow. A front-end loader will transport material from the blended material stockpile that is below 750 ppm PCBs and 15% moisture content into the hopper of an inclined belt conveyor. A weigh belt scale will measure the material feed rate into the CBCD. The conveyor will feed the hopper of the CBCD, with the material in the hopper providing the seal at the feed end of the CBCD. A twin screw feeder will transport material into the CBCD at a controlled rate. As material moves continuously through the CBCD, the temperature of the material will increase by indirect heat. The CBCD is essentially an inner-rotating drum surrounded by a fixed outer drum. Heated air produced from the combustion of #2 fuel oil (the oil burners are located external to the CBCD) will be released into the space between the inner and outer drums. The heat from this air will be transferred into the inner drum, heating the material as it moves through the CBCD. The heated air (burner exhaust gas) will not contact the waste material and will be released through stacks located on top of the CBCD. As the contaminated material travels from the feed end to the discharge end, the desired material temperature will be reached, resulting in partial chemical dechlorination/detoxification and physical separation of the contaminants (PCBs and dioxin/furans) from the materials into the vapor phase. A small portion of the burner exhaust gas, which has a low oxygen level, will be sent to the feed end of the CBCD and used as sweep gas to remove the contaminants/organics and water desorbed from the CBCD. The environment within the CBCD will be maintained as low oxygen (inert) to prevent combustion of organics within the CBCD. Nitrogen or inert gas will be added to the CBCD inlet and outlet seals to minimize oxygen intake, assuring the inert environment within the CBCD. The CBCD system is nominally designed for 15 tons per hour. The hot, treated material from the CBCD will be transferred to a discharge conveyor and into a double-shaft paddle mixer where water will be added to cool and rehydrate the treated material. Steam (from cooling of the material) and carryover particulates will be fed into a small scrubber, which will remove any particulate carryover and discharges clean air into the atmosphere. The cooled, hydrated material is discharged to the treated material stockpile area, utilizing a radial stacker. The treated material will then be sampled and analyzed to assure that the soil treatment standards are met. Once tested as clean, the materials will be relocated or backfilled. ETG Environmental. lnc./BF A Environmental Consultants 3 Final March 2000 Perfonnance Demonstration Plan iiiiiii' Warren County PCB Landfill The CBCD exhaust gases ( consisting of sweep gas, steam, and particulates) will pass through a hot cyclone to remove larger sized particulates. The removed particulates will be mixed with the treated materials for cooling and rehydration. The CBCD exhaust gases will exit the hot cyclone and enter into a direct contact quencher/scrubber. The quencher/scrubber uses direct contact water to rapidly cool the exhaust gases to condense steam and contaminants, as well as, to achieve additional particulate removal. The exhaust gases will then continue into a chilled water scrubber to achieve additional cooling/condensing and particulate removal, and then pass through a wet electrostatic precipitator (WESP) for final particulate/mist removal. The gases from the WESP will be reheated to reduce the relative humidity before entering into a flameless thermal oxidizer (FTO). An induced draft fan, located downstream of the reheater will be utilized to pull the gases through the VRS and maintain a slight negative pressure at the CBCD inlet. The FTO provides final polishing of the gases prior to discharge into the atmosphere through the process stack. The FTO virtually eliminates any non-condensable organics and residual organic contaminants that were not removed by the components of the CBCD-VRS described above. The process stack will be equipped with a continuous process monitor (CPM) to measure and record total hydrocarbons in the stack gas. The testing of stack emissions to determine that air treatment standards established for the project are met is further described in this PDP (Sections 3, 9 and 11 ), as well as the Air Monitoring Plan. A portion of the quencher/scrubber discharge is recycled to the inlet of the quencher/scrubber after being cooled through a non-contact plate type heat exchanger. The chilled water scrubber recycle is cooled utilizing prior to re-entering the scrubber. 2.2.1 Upset Conditions for CBCD The following are descriptions of bypass systems for the CBCD that are utilized in the event of upset conditions. a. The CBCD discharge screw conveyor can discharge material to a roll-off box to unload the CBCD in the event that the CBCD must be shut do\\'n. b. An emergency bypass, located upstream of the FTO fan, is provided to continue system operation in case of FTO upset. In this event, the bypassed air vapor will pass through carbon bed(s) before being discharged to the atmosphere. A back up generator will be installed to supply power to critical equipment ( e.g. discharge conveyor, ID fan. quencher/scrubber recycle pump, cooling tower recycle pump, emergency plant lighting, FTO fan, etc.), and the CBCD will be provided with a backup propane motor. Appendix A has been reserved for the equipment performance information to be provided by the Contractor. ETG Environmental, lnc.iBF A Environmental Consultants 4 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill • 2.3 Batch Vacuum Solid Phase BCDffhermal Desorption Unit (BBCD) The BBCD system allows for batch processing of the contaminated BCD blended materials, and specifically: • • • • • Treatment of materials that contain elevated levels of PCBs and/or moisture content without interfering with the production of the CBCD system, The BBCD can treat sludges, filter cake. spent carbon and filter media produced in the process condensate separation and aqueous phase treatment (PCSAPT) system, The BBCD allows for the treatment of concentrated organics, The BBCD may be the main producer of the organic stream for the LBCD system, and The BBCD and LBCD systems provide end points for the detoxification of the PCB contaminated materials. It is important to note that the BBCD system can treat all levels of PCB contamination and moisture content. The BBCD process flow diagram is provided in drawing PFD-203, which shows the major equipment components and solid, liquid and gas flows. Contaminated material will be prepared and blended as described in Section 2.1. Prepared material will be tested regularly for moisture content and PCB levels. This testing will determine whether material is sent to the CBCD or BBCD. The BBCD is designed to treat material with elevated PCB concentration greater than 750 milligrams per kilogram (mg/kg) or parts per million (ppm) and/or elevated moisture content (> 15% moisture). If no material with these levels of PCBs or moisture is excavated, the BBCD has operational flexibility to accept material with lower levels. The prepared material will be transferred by a front-end loader into a feed conveyor. From there. the material will be placed inside the rotating drum of the BBCD. The BBCD is similar to the CBCD in that the BBCD consists of an inner, rotating drum surrounded by a fixed. outer drum. Heated air from an external burner will be brought to optimum temperature in a burner box. The burner exhaust gas will then be directed into the desorption chamber though a central pipe. Once inside. additional pipes distribute the burner gas within the unit and then into the space between the inner and the outer drums. As the inner drum rotates, the material spills over the hot gas piping enhancing heat transfer though the unit. (There is no contact between the burner gas and the material.) Burner gases are discharged from the outer drum via a stack on top of the chamber. As the heat is conducted into the BBCD, an external pump applies vacuum. The temperature of the material is elevated to the desired level, initiating partial dechlorination/detoxification and thermal desorption of the contaminants/organics and water. By application of vacuum, oxygen is evacuated from the BBCD, resulting in an inert environment. The agitation of material combined with heat and vacuum result in efficient BCD treatment of contaminated materials. During the heating cycle, gases containing water, organics and particulates are removed from the BBCD by the external vacuum pump. The BBCD exhaust gases pass through a hot cyclone for large particulate removal. The removed particulates, if clean, will be mixed with ETG Environmental. Inc ./BF A Environmental Consultants 5 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill • the treated materials for cooling and rehydration; otherwise the collected particulates will be retreated in a subsequent batch cycle. BBCD exhaust gases will continue into a direct contact quencher/scrubber for cooling and additional particulate removal. The temperature of the exhaust gases will be quickly reduced by the direct contact with cooling water. which results in condensing of water and organics . . The cooled gases continue into a non-contact. shell-and-tube condenser for additional recovery of steam and organics. The gases then pass through a liquid ring vacuum pump into another condenser on the positive pressure side of the vacuum pump. The non-contact condensers utilize chilled water: the quencher/scrubber utilizes cooling tower water. At the conclusion of the batch cycle. the treated material will be removed by reversing the rotational direction of the BBCD inner drum. This hot, treated material is discharged into a mixer where water is added to cool and rehydrate the treated material. As with the CBCD, steam and particulates from the mixer enter a scrubber to be removed prior to discharge to the atmosphere. The cool. hydrated treated material will be discharged to the treated material stockpile for sampling and analysis. Clean treated material will be relocated or backfilled. Appendix B has been reserved for the BBCD equipment performance information to be provided by the Contractor. 2.3.1 Upset Conditions for BBCD An emergency bypass located upstream of the FTO fan. will be provided to continue system operation in case of FTO upset. In this event, the bypassed air vapor will pass through carbon bed(s) before being discharged to the atmosphere. In the event of a power failure in the batch system, the backup generator will power critical equipment associated with the batch system (i.e., vacuum pump, cooling water recirculating pump, FTO fan, etc.). 2.4 Process Condensate Separation and Aqueous Phase Treatment System (PCSAPT) Condensate will be collected from both the CBCD-VRS and the BBCD-VRS as illustrated in the process flow diagrams (Drawings PFD-202 and PFD-203). Drawing PFD-204 depicts the PCSAPT system. Condensate from the BBCD will be treated after the soil desorption process is complete (heating and cooling cycle). The condensate will be pumped to a centrifuge for separation of the organics and aqueous phases. The separated organics will be pumped to the organics tank. The aqueous phase will be pumped to the condensate collection tank. Bleed from the quencher/scrubber of the CBCD-VRS discharges directly into the condensate collection tank. The condensate collection tank also collects bleed from the chilled water scrubber, WESP, and the BBCD aqueous phase. Light organics may separate as "floaters" which can be skimmed off of the top and sent to the LBCD organic feed tank. ETG Environmental, Inc./BF A Environmental Consultants 6 Final March 2000 Performance Demonstration Plan Warren County PCB Landfill • Liquor pumped from the bottom of the condensate collection tank will enter a sludge holding tank to be homogenized prior to feed into a filter press to achieve liquid/solids separation. The sludge holding and condensate collection tanks also act as surge tanks when the filter press is in its cake discharge cycle. Due to the anticipated oily nature of the sludge holding tank liquor. a precoat will be used during each filter press cycle. The filter press system includes a precoat feed tank and precoat feed pumps. The sludge holding tank liquor will be pumped through the filter press using a diaphragm pump. When the pressure in the filter press reaches the maximum desired operating pressure, the diaphragm pump will be turned off and the filter press plates pressed to remove additional entrapped filtrate. At the completion of the press cycle, the pressure is released and the plates opened to drop the filter cake. The filter cake will be dumped into a storage container designed to be watertight and easily transported via fork truck. Filter cake will be sent to the BBCD for treatment as contaminated materials. due to its high moisture content, possibility of elevated PCBs. and the ability of the BBCD system to concentrate PCBs in the organic liquids. Filtrate from the filter press will continue into a storage tank. The storage serves as a surge tank and allows for additional physical separation of the filtrate into organic and aqueous phases. The organic fraction from the filtrate storage tank will be transferred to the LBCD organic feed tank. The aqueous phase will continue into the aqueous phase treatment components of the PCSAPT. The aqueous phase treatment will consist of particulate and organic removal devices. Filtrate from the filter storage tank will be pumped through a sand filter for final polishing of suspended solids. Depending upon the concentration and particle size distribution of the residual suspended solids and oil content of the filtrate. a multi media filter maybe substituted for the single layer sand filter. In either situation, the filter system will be equipped with a backwash system capable of removing sediment buildup. Water from the water storage tank will be used to backwash the filter media. The backwash water will be discharged into the condensate collection tank. The backwash system can be operated manually or automatically using either a differential pressure gauge or on a timed backup system. At a minimum, two media filters will be available to permit backwashing of one unit while the other is in operation. The filtrate passing through the filter media will pass through a minimum of two carbon vessels placed in series. There will be two dual carbon systems to permit continuous processing through the carbon system while the one system is under going a carbon change. Spent carbon and spent media filter will be treated in the BBCD system. The treated aqueous phase will be stored in the water storage tank. The effluent standard for the treated aqueous phase is set at the same standard for the treated soils, i.e. 200 ppb PCBs or less. The treated aqueous phase will then be suitable for recycling back into the BCD ETG Environmental, Jnc./BF A Environmental Consultants 7 Final March 2000 ·..:..• Perfonnance Demonstration Plan Warren County PCB Landfill process, being primarily used for rehydration of the treated soils. As a backup system to ensure sufficient water is always available for the rehydration of the treated soils, a city water line will also be connected to the water storage tank. 2.5 Liquid Phase BCD Detoxification System Drawing PFD-205 contains a process flow diagram for the batch liquid BCD detoxification system. The LBCD system allows for batch processing of the PCB contaminated liquids and/or sludges. The batch LBCD system provides for an end point for the detoxification of the PCB contaminated materials. Organic materials from the PCSAPT will be sent to the liquid phase BCD detoxification system (LBCD). LBCD employs a potassium/sodium-based reagent, a hydrogen donor in the form of a high boiling point carrier oil, and catalyst to chemically detoxify the chlorinaied contaminants (PCBs. dioxins/furans). The carrier oils along with reagent. catalyst. and the contaminated liquids are placed in the reactor and heated to 600-650° F. Nitrogen will be used as necessary to provide an inert atmosphere within the LBCD reactor. The overall liquid BCD reaction process is represented as follows: Catalysts Acceptor -Cl + NaOH + Donor - H 600-650 F ------➔Donor+ Acceptor-H +NaCl+ H2O (Acceptor -Cl represents PCBs and polychlorinated dioxins/furans) During the LBCD process. gases (steam and light organics) will be forced through a condenser by the vapor pressure generated by the gas stream. The LBCD reactor is designed to operate at or below 5 pounds per square inch (psi). The condenser will cool the gases using non-contact chilled liquid from the chiller and separate gases that condense above 60- 800F. The gases will be vented to the CBCD-FTO for polishing before being discharged to the atmosphere. Samples of the oil mixture will be drawn from the sampling ports and screened for PCBs during processing. Once the PCBs concentration of the oil mixture has been reduced to a concentration acceptable for off-site disposal, the batch will be continued for an additional 1- 2 hours to ensure the completion of dechlorination. At the end of each batch, the liquid mixture will be cooled using a heat exchanger. The liquid will then be sent to the organics transfer tank for phase separation. The aqueous phase, if any, will be pumped to the PCSAPT for further treatment. The aqueous phase will be monitored for pH and if necessary neutralized as it is pumped to the condensate collection tank. Organics will then be pumped to the treated organic tank. When sufficient quantity of organics are collected for disposal off-site, a sample will be obtained and analyzed for the parameters required by the specific disposal facility. Upon acceptance by the disposal facility, the treated organics will be transported to their facility. The LBCD reactor design capacity is 600 gallons. The batch time is expected to be 8 -I 0 hours. Appendix C has been reserved for the LBCD manufacturer performance information. ETG Environmental. lnc./BF A Environmental Consultants 8 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill -. 2.6 Utility Requirements for CBCD, BBCD, PCSAPT, and LBCD The entire BCD System takes advantage of non-contact systems for heating the contaminated materials. These systems isolate the contaminated materials, thereby minimizing the waste stream that must be cleaned or disposed. Design capacity is approximately 15-16 tons per hour (tph) for the CBCD/BBCD systems combined. The LBCD system capacity is dependent upon PCB matrix and concentration of the PCBs. The entire system requires approximately 120-180 gallons per hour (gph) of #2 fuel oil and 2000 amp/480 volt 3 phase electricity. Water usage may range from 15-50 gpm. The factors affecting production rate include, but are not limited to, feed material moisture content. type of feed soils. system availability, weather, etc. A local power company will provide electric power for the system. its ancillary equipment, office trailers, decontamination areas. and other activities as needed. Fuel oil tanks and propane storage tanks will be located in a clean area adjacent to the treatment area. Fuel oil and propane piping will be installed from the storage tanks to the burners on each thermal desorption unit. All installations. procedures, equipment. and materials for the fuel oil and propane supply system adhere to applicable National Fire Protection Association (NFPA) and local regulations. In addition. an emergency generator will be installed prior to the performance demonstration test to provide necessary power to operate equipment essential for a safe shutdown of the equipment in case of power failure. A propane driven motor is provided to turn the CBCD drum in the event of a power failure or motor failure. Phone service will be provided to the site for communication and downloading, if desired, information gathered by the control systems. ETG Environmental, lnc ./BF A Environmental Consultants 9 Final March 2000 Perfonnance Demonstration Plan Warren County PCBLandfill 3.0 PERFORMANCE DEMONSTRATION The contractor will prepare and submit TSCA permit applications and demonstration test plans for: • Research and Development permit; • Performance Demonstration permit; • Operating permit for PCB Disposal by Non-Thermal Alternative Methods; and • Operating permit for PCB Incinerators. In addition, the contractors will prepare and submit an air discharge permit application with the North Carolina Division of Air Quality. 3.1 Material (soil) Treatment Standards The Warren County PCB Landfill is a closed TSCA landfill. The Governor and the State legislature are committed to the detoxification of the landfill and the joint Warren County - State PCB Landfill Working Group, on which some State officials serve, selected the BCD technology. The detoxification of the landfill represents a voluntary closure of this facility. The Working Group determined treatment standards for residual concentrations of contaminants remaining in the material above which treatment is necessary. However, it is recognized that these standards are more stringent than those typically required by USEP A or North Carolina Department of Environment and Natural Resources (NCDENR) for PCB cleanups. These treatment standards represent the desire of the Working Group to obtain a stringent cleanup that is highly protective of public health. The standards for material are as follows: a. PCBs -200 parts per billion (ppb) b. Dioxins/furans -200 parts per trillion (ppt) Toxicity Equivalent Concentration (TEQ) Based on the results of the treatability study conducted with site materials in 1998, all of the materials that are processed in the CBCD/BBCD are expected to meet the treated material (soil) performance standards in one pass through the units. Treated soil (including hot cyclone dust) will be back-filled on-site once testing has confirmed that the soil has met performance standards. Material that does not achieve the performance standards will be retreated. Condensate discharge from the CBCD/BBCD will be separated and treated on-site. The treated condensate will be used to cool and re-hydrate the treated material. Material sampling for compliance with the material treatment standards will be conducted after the treated condensate is added to the treated material. 3.2 Stack Emissions During full scale operation, there will be two stack discharge points from the BCD thermal desorption processes, one from the CBCD, and the other from the BBCD. The VRS ETG Environmental. lnc ./BF A Environmental Consultants 10 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill equipment has been designed based on the results of pilot scale testing on soil that contained typical levels of contamination. Contingencies were accounted for in the design of the VRS 's to handle variability in site soil conditions to ensure compliance with emission limits. During the performance demonstration (PD) test, stack emissions will be quantified by conducting stack sampling and analysis. The results of the PD test stack sampling will then be compared to the TSCA regulatory requirements and the applicable State of North Carolina regulations presented in Appendix D to demonstrate compliance. The regulations for stack emissions include standards for visible emissions, particulate matter, and toxic air pollutants (TAPs). In order to demonstrate that T APs are within regulated limits, air dispersion modeling and stack sampling and analysis will be performed. The NCDENR, Division of Air Quality Management Administration has established T APs screening levels, which provide an off- site. risk-based concentration for each TAP. Through the air dispersion modeling, allowable concentrations of each TAP emitted at the stack is established so that off-site concentration does not exceed the risk-based screening level. The actual stack concentrations measured during the PD test are then compared to the allowable stack emission limits to ensure the limits are not exceeded. A table of the North Carolina T APs screening levels and further details of the air dispersion modeling used to establish the allowable stack emissions, are presented in Appendix D. 3.3 Process Condensate Process condensate is generated from the CBCD and BBCD scrubbers/condensers, and the WESP. Process condensate will be separated and treated onsite in the PCSAPT. The treated aqueous phase condensate will be re-used within the CBCD/BBCD cooling mixer for soil rehydration. The BCD thermal desorption process is a net water user, and therefore, it is not expected that water will be discharged from the process. The PCSAPT will be designed to allow the treated aqueous phase condensate to be used to rehydrate the materials with the materials meeting the established treatment standards for PCBs. 3.4 Process Organics The process condensate generated from CBCD/BBCD scrubbers/condensers will be treated in the PCSAPTs. Separated organics (filter cake and/or organics separated by the PCSAPTs) will be treated in the LBCD. The LBCD is designed as a closed loop batch processing system. Gases generated during LBCD processing are condensed in a reflux condenser collected and treated as appropriate. The PCB laden organics will be treated in the LBCD to a standard acceptable for off-site disposal.

ETG Environmental, Inc./BF A Environmental Consultants 12 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill 5.0 WASTE FEED CHARACTERIZATION The Warren County PCB Landfill was specifically designed to accept PCB contaminated soils excavated along approximately 270 miles of roadway. Approximately 32,000 cubic yards of soils were received from State highway soils and another 8,000 cubic yards of soils were received from Fort Bragg, North Carolina. An area three feet wide and three inches in depth was excavated from along the roadways. Included in the excavation was the grass and under bush which were fairly extensive. The areas contaminated with PCBs were restricted from any activity from the time of discovery until the soils were excavated, allowing the grass and under bush to become quite thick. The soil organic matter content was analyzed and reported to be in the range of 2 to 5 percent. Prior to excavating the soils. a mixture of carbon slurry was sprayed on to the contaminated soils in an attempt to remediate the soils in place. The carbon slurry was placed at a rate of 1.477.96 pounds per shoulder mile: for a total of 155.90 tons of activated charcoal used. Following the placement of the carbon slurry, a thin layer of liquid asphalt tacking was sprayed in an effort to secure the carbon in place. This technology was eventually not acceptable to the EPA resulting in the necessity to excavate the soils. During the excavation, process water was sprayed onto the soils to reduce dust emissions. The soils were again sprayed with water for dust control measures during the actual loading out of the soils into trucks. In November 1982, Soil & Material Engineers, Inc. (S&ME) installed four soil borings into the landfill. Contained in Appendix E are the soil boring logs and moisture content results. In February 1997, S&ME installed two borings into the landfill for the purpose of investigating the integrity of the clay caps and to install two recovery wells. Unlike the soil borings installed in 1982. which used split spoon samplers to collect soil samples through the boring, soils were collected off the flights of the auger. The soils collected off the flights in 1997 were analyzed for moisture content. bulk density, dry density, particle size distribution, plasticity, specific gravity, organic content and permeability. Results of these tests are also included in Appendix E and are summarized on Table GTX-1380. The soils collected in February 1997 were given a soil classification of SM-silty sands using American Society for Testing and Materials (ASTM) Method D 2487. The soil description provided in the S&ME logs from November 1982 provide the following soil classifications: • Fine to medium sandy silt, • Fine to medium silty sand, • Fine to medium sandy clay, • Fine to medium silty sandy clay, • Fine to medium sandy clayey silt, • Fine to medium slightly clayey sand, • Fine to medium slightly clayey sandy silt, • Fine to medium to coarse silty sand, and • Fine to medium to coarse slightly clayey silty sand. ETG Environmental, lnc./BF A Environmental Consultants 13 Final March 2000 Performance Demonstration Plan Warren County PCB Landfill Using ASTM Method D 422, 83% to 99 % of the PCB contaminated soils collected in 1997 passed through the #4 sieve and 13% to 22% passed through the #200 sieve. There is anticipated to be minimal large oversized debris as a result of the method used to excavate the soils from the roadways, however, there will be some debris including gravel that may not pass a 2 inch by 2 inch screen. The moisture content of the PCB contaminated soils collected in 1982 as determined through ASTM Method D 2216 ranges between a low of 5.6% to a high of 28.4%. Tests performed on samples collected in 1997 provided similar results. Further tests conducted by GeoTesting Express on the PCB contaminated soils collected in 1997 indicated the soils to be not plastic. an organic content of 2% to almost 5% and a specific gravity range from 2.59 to 2.64. Appendix E also contains two tables of analytical results from an unknown source titled "Physical Characterization of PCB Contaminated Soils in Warren County"' and ''Chemical Characterization of PCB Contaminated Soils in Warren County". Tables 4-1 through 4-4 of ETG · s Pilot Scale Test Report provide analytical results of tests performed on the untreated rav,' materials provided to ETG for the pilot test. Other than PCBs there were no other chemical constituents of concern. Prior to treatment. the excavated materials will be sampled and analyzed for PCBs using the immunoassay PCB Screen and moisture content. The data generated along with physical characteristics of the material will be used to determine the material treatment scenario - CBCD or BBCD (Appendix F provides a guideline for such determination). It is imperative that the contaminated material used for the PD tests be of sufficient PCB concentration to demonstrate the effectiveness of the BBCD and CBCD processes to permit the full-scale operation of the BCD systems, for the full range of PCB concentrations anticipated for this project. Should the PCB concentration of the excavated materials be deemed insufficient by NCDENR and/or any other regulatory agency to judge the effectiveness of the BCD system, then the materials will be spiked with PCB oil to obtain the desired PCB concentration level. ETG Environmental. Jnc./BF A Environmental Consultants 14 Final March 2000 Performance Demonstration Plan Warren County PCB Landfill 6.0 STORMWATER/DECONT AMINATION WATER COLLECTION, STORAGE, AND TREATMENT During the Performance Demonstration, stormwater/decontamination water will be collected and stored for treatment and reuse on-site. During interim and full-scale operations, the stormwater/decontamination water treatment system will be fully operational and designed to utilize treated water for reuse on-site. The system is described as follows: 6.1 Decontamination Water Decontamination water will be generated from cleaning trucks, loaders and other equipment that come in contact with contaminated materials. Decontamination will be performed only on the decontamination pad where the water will be collected in sumps and transferred via pipe to a lined pond. The lined pond will also collect contaminated stormwater. Water from the lined pond will be pumped to a treatment system comprised of sand filtration followed by carbon polishing. The effluent will be discharged to the existing unlined pond at the site. 6.2 Stormwater Untreated material will be handled primarily under a structure with a roof to mm1m1ze contact with stormwater. The existing grade in the treatment area slopes from the treated material storage area down to the contaminated material area, with man-made diversions in place. This effect will minimize contact of stormwater with contaminated material and will ensure that any contaminated stormwater will not flow into uncontaminated areas. Stormwater suspected of being contaminated will be collected and treated on-site with the decontamination water, before being reused or discharged to an unlined pond. Also, any excess water from dewatering of excavated materials will be collected and treated within this system. ETG Environmental. lnc.1BF A Environmental Consultants 15 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill 7.0 PROCESS MONITORING PROCEDURES Operating parameters will be monitored to assure the efficient operation of system components and to establish the acceptable range of operating conditions. Table 7-1 identifies a preliminary list of the parameters, instruments, target values, frequency, instrument range, accuracy and calibration for the CBCD. Table 7-2 and Table 7-3 presents the same preliminary categories of infomrntion for the BBCD, and LBCD. respectively. These tables also indicate which parameters are recorded. The values for these parameters will be stored in a computer and can be made available for review. When process instrumentation indicate operations outside prescribed ranges. an alarm will be triggered warning the operator. The operator can then make the necessary adjustments to allow the system to operate within normal parameters. 7.1 Waste Feed Cutoff Systems The purpose of the Waste Feed Cutoff (WFC) systems is to provide a mechanism for immediate action whenever operating parameters deviate outside normal control limits. There are both automatic and manual waste feed cutoff conditions. The WFC systems are not applicable to the BBCD or the LBCD and, therefore. none are provided. Table 7-4 provides a preliminary list of the WFC parameters and actions to take if parameters deviate outside of the normal operations range. The CBCD waste feed conveyor will be shut off automatically if the following parameters are outside limits for normal operations: 1) CBCD desorber face pressure; 2) CBCD material exit temperature; 3) CBCD gas exit temperature; and 4) WESP exit gas temperature. In addition to the operating parameters shown on Tables 7-1 and 7-2, the total hydrocarbon analyzer in the stacks' continuous process monitoring system will be checked for calibration every day. The allowable operating range will be determined during the performance demonstration test. If the drift of the analyzer exceeds the allowable limit, the analyzer's calibration will be re-checked for accuracy. If accurate, the process will be shut off pending further evaluation. The waste feed system will also shut off automatically if a power failure occurs or the discharge system fails. The CBCD shall be provided with a propane powered emergency drive to continue rotating the CBCD drum at a very slow rate in case of power failure. A back up generator will be started to supply power to critical equipment (i.e. discharge conveyor, induced draft fan, quencher/scrubber recycle pump, cooling tower recycle pump, emergency plant lighting, FTO fan, etc.). In the event of a power failure in the batch system, critical equipment (i.e., vacuum pump, cooling tower recycle pump, FTO fan, etc.) will be powered by the backup generator. A description of these components is provided in Section 2.0. Visual inspection of particulate emissions from the stack, or any unusual situation that may occur that would require further inspection, will trigger a manual WFC. When the parameters deviate from the target values listed in Table 7-4 for the amount of time indicated, an automatic WFC will be activated. These parameters will be monitored continuously by system operators and will be checked by the on-duty supervisor. ETG Environmental. lnc./BF A Environmental Consultants 16 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill The WFC procedures provide assurances that the system will be operated within accepted operating conditions to accomplish the following: I) protection of human health ( off-site and on-site) and the environment, and 2) prevent damage to the equipment. If the WFC system is initiated. discharged soil will be segregated and sampled to determine if soil treatment standards have been met. At any point during operation of the CBCD. the operator has the option to initiate a WFC sequence manually. The protocol for conducting a WFC is as follows: a. The operator will first stop the feed and operation of the feed conveyor to a level in the hopper portion where a material seal is maintained to prevent ambient air from entering the CBCD. b. The CBCD will continue to process material until it is empty and discharge to the stockpile through the discharge screw, double paddle mixer/cooler. and stacking conveyor. c. The firing rate for the CBCD burners will be reduced due to the termination of material feed. Shell temperature will be closely monitored as the remaining material progresses through the unit. d. The use of treated process aqueous phase condensate to re-hydrate the treated materials will be discontinued when material is no longer being discharged into the double paddle mixer/cooler. e. The induced draft fan will maintain a slight draft in the CBCD to purge the system of process gases. Therefore. condensation of cooled gases and subsequent vapor phase treatment will continue to occur. Condensate collection separation and treatment will continue to occur until flows decline to a negligible level. f. The scrubbers will be manually shut down as the process gas drops below minimum temperature. g. The induced draft fan will be shut down.

Following is an overview of the schedule of events leading up to the PD testing: Months 1-3: Prepare plans. submit permit applications, initiate equipment procurement, and implement Community OutReach and Involvement Plan. Months 3-4: Continue with Month ·s 1-3 activities, initiate site preparation activities, base line monitoring, clearing and grubbing. site security, temporary facilities, install utilities. Months 5-6: Install process pads and begin receiving equipment. Months 7-9: Build roof covered areas for soil. install power. complete receipt of equipment. finish component assembly. install conveyance piping from/to process condensate treatment facility and storm water treatment plants. begin shake down and perform clean soil tests. Month I 0: -Finish clean soil tests. and begin first of six PD tests. 8.1 Clean Material-CBCD/BBCD ShakeDown The purpose of the clean soil testing is to verify mechanical operation of the CBCD and BBCD systems. Prior to operations with contaminated materials, both CBCD and BBCD systems will process clean soil for 8 hours at anticipated feed rates and retention times. This amount of time is the minimum needed to ensure that all system components are functioning properly. Key information to be collected for the CBCD includes: soil feed rate, clean soil moisture content. soil exit temperature. and material handling and vapor recovery system (CBCD- VRS) equipment performance. Key information to be collected for the BBCD clean soil test includes: batch volume, vacuum pressure at the hot cyclone inlet. soil temperature verses time, and material handling and BBCD-VRS equipment performance. Approximately 10 to 12 tons of clean soil will be treated in the BBCD system and 120 -200 tons of clean soil treated in the CBCD system. 8.2 Contaminated Material -CBCD/BBCD PD TEST The goal of the PD testing is to demonstrate that the CBCD/BBCD systems can achieve the material treatment standards and stack emissions while processing maximum throughput. PD testing will be conducted on each type of BCD system (i.e. BBCD and CBCD). A rigorous monitoring and sampling program will ensure that requirements are met for all systems ETG Environmental. lnc./BF A Environmental Consultants 22 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill during full scale operations. Sampling and analysis will be conducted in accordance with Section 9.0. In accordance with the excavation plan described in the Site Operations Work Plan, the southern end of the PCB landfill will be uncovered and PCB contaminated material excavated. The excavated material will be transported via trucks to the screening and blending plant. The material will be v.;eighed using a truck scale that has been certified prior to staging at the screening and blending plant. Sufficient material will be excavated to perform the ramp up test on the CBCD and the three PD tests to be performed on the CBCD and BBCD systems. Samples of the staged excavated material will be collected. The samples will be screened in the field for PCBs using the immunoassay kits and analyzed for moisture content. In addition, samples will be submitted to a laboratory for PCBs, dioxin/furans and hazardous waste chemical characterization. The PCB and dioxin/furans analyses provide data on the concentration of the PCBs in the material. and the hazardous waste chemical characterization will confirm that no other chemicals of concern exist in the PCB contaminated materials. It is desired to perform the PD tests with materials representative of the levels of PCBs anticipated to be encountered throughout the project. If the material excavated is not of sufficient PCB concentrations then it will be spiked with PCBs. Materials with a moisture content greater than 15 percent will be treated in the BBCD system. The staged material will be loaded into the hopper of the screening plant contammg a maximum screen mesh size of 2-inch by 2-inch. Material not passing through the 2-inch by 2-inch screen will be discarded into an oversize pile. Material passing through the 2-inch by 2-inch screen will pass under a magnet to remove magnetic materials. Magnetic material collected on the magnet will be removed manually and placed in a stockpile for future decontamination and disposal. The non-magnetic screened material will be transferred to the pug mill plant where BCD reagents will be blended at a ratio of 2% to 5% by weight. Following is a description of the PD testing that will be performed: • The first test to be performed is the CBCD ramp-up test to determine the highest feed rate that will still produce material meeting the soil cleanup standard of 200 ppb PCBs. The CBCD will start with contaminated material and will slowly ramp up to maximum throughput conditions (i.e., highest feed rate and lowest material retention time that will still produce clean material). Contaminated material is needed to make this determination. This ramp up time may take approximately 24 hours or more to complete. The CBCD will then be shutdown for analysis of operational control parameters. • The day after the CBCD ramp up test is complete, PD testing will begin on the BBCD. Material will be added to the BBCD and the test will be started in the morning. Once heat is applied to the unit, the PD test will be started. The second and third BBCD PD tests are expected to occur during the two days following the first test. The operating ETG Environmental. Inc./BF A Environmental Consultants 23 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill time for each PD test of the batch system is anticipated to be completed within 9 to 12 hours. All three PD tests will be conducted at maximum throughput operating conditions (i.e., largest possible feed to the unit expected during full-scale operations). • After BBCD testing is complete, PD testing will continue on the CBCD. The test will be started in the morning. Once the CBCD has reached the proper temperature, material will be added. Once the feed rate is stabilized, the PD test will be started. The second and third CBCD PD tests are expected to occur on the two days following the first test. All three PD tests of the continuous system are expected to be completed within 9 to 16 hours of starting up the CBCD. In between tests, the CBCD will most likely be kept at or near the operating temperature. All three PD tests will be conducted at maximum throughput operating conditions (i.e .. highest feed rate and lowest retention time expected during full scale operations). Treated and untreated material. air. and condensate sampling will be conducted and the samples will be sent to a laboratory for detailed analyses during ramp up of the CBCD and the six PD tests. Because stack sampling may take up to 9 hours to complete, each PD test will last at least that long. Refer to Section 9.0 for details pertaining to sampling and analysis. In addition, critical process control data is monitored and recorded as described in Section 7.0. Successful PD test data (i.e .. chemical analyses confirming air and treatment standards are achieved) will be evaluated to establish an operating range for total hydrocarbon compounds as measured by continuous process monitor. This range will then be used as a guideline that the system is operating within the required emission standards. A detailed test report and compilation of test data will be submitted to NCDENR at the conclusion of PD testing. An outline of this report is shown in Appendix G. Interim operations will be conducted as described in Section l 0.0 after PD testing is completed. 8.3 Liquid BCD Reactor Prior to the treatment of PCB contaminated organic liquids, the liquid BCD reactor will be tested for mechanical operation. Carrier oil, catalysts, and process additives will be metered into the reactor and heated to 600 -650°F. Feed rates, batch volume, reactor pressure, and process liquid temperature will be monitored to determine that the equipment will operate as designed. The goal of the PD testing for the liquid BCD reactor is to demonstrate that the contaminated organic liquids from CBCD and BBCD process condensate will be treated to the required criteria as determined by the off-site disposal facility The first test will be started after the completion of both CBCD and BBCD PD tests. Samples of the organic mixture will be drawn from the sampling ports and screened for PCBs to determine the completion of the BCD process. At the end of the batch, process oil samples will be taken and sent to a commercial laboratory for detail analysis according to ETG Environmental. Inc./BF A Environmental Consu I tan ts 24 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill sampling and analysis procedures described in Section 9.0. A single PD test is anticipated to be completed in 8-10 hours. Critical process control data is also monitored and recorded as described in Section 7.0. It is imperative that the PCB contaminated organic liquid be of sufficient PCB concentration to demonstrate the effectiveness of the LBCD system for NCDENR and/or other regulatory agencies. If need be, the organic liquids to be treated will be spiked with PCB oil to achieve the desired PCB concentration levels. ETG Environmental, lnc./BFA Environmental Consultants 25 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill 9.0 PERFORMANCE DEMONSTRATION SAMPLING AND ANALYSIS During PD testing, the BBCD/CBCD will be tested to demonstrate that material treatment and air emission standards have been achieved. Treated process condensate and stormwater/decontamination water will also be tested to verify proper operation of these systems. Three replicate tests will be conducted for the BBCD, CBCD and LBCD systems. Each test will be performed during a 6 to 12 hour period. All sampling and analysis will be conducted in accordance with the approved sampling and analysis plan. which is summarized in Table 9-1. The Final Verification/Confirmation Sampling Plan (FVCSP) includes the procedures to be used for each sampling event. These sampling procedures will be used to ensure proper sampling protocols are adhered to during sampling. NCDENR will also review and approve the use of these sampling procedures prior to PD testing. Material will be selected for PD testing as described in Section 5.0. In summary, performance of the BBCD will be demonstrated through the processing of excavated materials exhibiting elevated PCB concentrations and/or moisture content. Contaminated materials considered representative of the majority of material that will be encountered at the site will be excavated and used to evaluate the CBCD. The excavated material will be sampled in accordance with the FVCSP and screened for PCBs and moisture content on-site to verify that it is representative of material to be treated in the CBCD. In the event that the material is not representative, then another source of contaminated material will be identified based on historical sample results, or the materials will be spiked with PCB oil to achieve the desired concentrations. Table 9-1 presents the estimated number and types of samples that will be collected and analyzed to demonstrate attainment of standards (this Table does not include any sampling and analysis associated with the ramp up). 9.1 Untreated Feed Material Chemical and physical analyses will be performed on the untreated feed material to assess characteristics and provide physical data to determine if the material will be treated by the BBCD or CBCD system. Additionally, this information will be used to evaluate handling methods and requirements before and after treatment. For the ramp up, one stockpile will be created and sampled following the procedure in the FVCSP. One composite sample will be analyzed on-site using the Immunoassay kit for PCBs and percent moisture. For each PD test run after the CBCD ramp up test, six material stockpiles will be created, one for each of the three BBCD tests and one for each of the three CBCD tests. Untreated feed material will be stockpiled, sampled (see FVCSP) and analyzed for PCBs, semi-volatile organic compounds (SVOCs), VOCs, dioxin/furans, total chlorides, metals, percent moisture, and density. Eight locations from each stockpile will be selected so that representative soil types and contaminant concentr~tions are sampled. Material from the eight locations will be collected and homogenized in a stainless steel bowl using a stainless steel trowel before ETG Environmental, lnc ./BF A Environmental Consultants 26 Final March 2000 Performance Demonstration Plan Warren County PCB Landfill being placed in the appropriate sampling container, with the exception of samples requiring VOC analysis. Four VOC samples will be collected directly into sample jars at four locations using a disposable spatula. The material will then be screened utilizing a 2 inch by 2 inch screen. Oversize material will be stored in a designated area for additional handling. 9.2 Treated Material During ramp up for the CBCD, one grab sample per each feed rate/retention time will be collected and analyzed onsite utilizing the immunoassay kit for PCBs. This data will be compared with material treatment standards and used to determine the maximum throughput rate for the PD tests. Note: The number of samples collected and analyzed will be Contractor specific and have not been listed in Table 9-1. These samples are for the Contractor to determine the feed rate to be used for the PD tests. The ability of the CBCD/BBCD to produce material that meets the project material treatment standards listed below will be demonstrated during the PD tests: • Project Material Treatment Standard: PCBs <200ppb, Dioxin <200 ppt TEQ For each PD test run, the conveyor from the CBCD will deposit treated material creating four stockpiles. For the BBCD, a single treated material stockpile will be created. The appropriate precautions will be taken in handling the treated material as temperatures may remain elevated within the stockpile. Samples to be analyzed for non volatile organic compounds will be collected as follows: • Two samples will be collected from each of the four CBCD stockpiles generated per PD test, for a total of eight samples. • Eight samples will be collected from the single BBCD stockpile generated per PD test. • The eight CBCD treated material samples will be homogenized in a stainless steel bowl using a stainless steel trowel before being placed in the appropriate sampling containers. • The eight BBCD treated material samples will be homogenized identical to the CBCD treated materials samples. Note: Never are the CBCD treated samples and BBCD treated samples homogenized together. Samples to be analyzed for volatile organic compounds will be collected as follows: • One sample from two of the four CBCD treated stockpiles will be collected and placed directly into sample jars. • Two samples from the BBCD treated stockpile will be collected and placed directly into sample jars.

During the processing, samples of the treated organics will be collected and screened for PCBs using an on-site immunoassay kit to determine the completion of the reactions. After the batch is completed, the treated organics will be processed through a centrifuge for removal of solids/salts. The solids/salts will be recycled back to the BBCD. The organic centrate will be pumped to a treated organic tank. When sufficient quantity of treated organics have been collected a grab sample will be collected and analyzed for PCBs and disposal parameters required by the disposal facility. 9.4 Air -Process Monitoring Stack emission tests will be conducted during the PD test to verify that CBCD/BBCD air emissions meet the established project requirements. Air samples will also be collected before the FTO to monitor its effectiveness. Three replicate stack tests will be conducted for each of the BBCD and CBCD PD tests. The stack sampling data collected during the PD tests will be compared to the allowable stack emissions determined by the air dispersion modeling. Appendix D provides an explanation of the model including inputs and resultant stack emission limits. Table 9-1 contains the sampling and analysis requirements for air san1ples. During the ramp up and throughout all of the PD testing, stack gas will be monitored for THC utilizing the CPM. All sampling protocols will be provided by the stack testing subcontractor and approved by NCDENR. ETG Environmental. Inc./BF A Environmental Consultants 32 Final March 2000 Perfonnance Demonstration Plan Warren County PCB Landfill 10.0 INTERIM OPERATIONS The BCD detoxification system will be shutdown until a TSCA operating permit is received. According to Mr. Winston Lue of the office of Pollution, Prevention and Toxics branch of TSCA, an interim operating permit may be issued to shorten the downtime between the conclusion of the PD test and the startup of the full-scale remediation operations. A Research and Development permit may be obtained to conduct the shakedown phase prior to proceeding with the Performance Demonstration test. Factors affecting the review process for both the interim permit and full-scale operating permit are: • Turnaround time for the stack testing results and laboratory analytical results: • Submission and quality of the Performance Demonstration Report: • Quality Assurance and Quality Control of the analytical data; • Consistency of analytical results collected from the three PD tests; • Delta between analytical results and treatment standards (air. and treated materials). • Mechanical performance of the processes (consistency, accuracy. instrumentation, operating parameters. etc.) The recommended schedule to expedite the TSCA permitting process from the completion of the PD test is as follows: Activity Stack Test Results Preliminary Compile Process Data Draft PD Report Submit Preliminary Data to NCDENR/ TSCA Stack Test Results Final Submit PD Report to NCDENR Receive NCDENR Comments Finalize PD Report Issue to NCDENR/TSCA TSCA Review/Respond to Questions Interim Permit Issued Commence BCD Detoxification Processing Final Permit Issued Time Line Week3 Week4 Week 5 Week6 Week 7 Week 8 Week 9 Week 11 Week 12 Week 13 Week 34 The Contractor is required to prepare a Performance Demonstration Report. The suggested outline of this report is presented in Appendix G. The project will commence under an interim permit until the final operating permit is received from TSCA. It will be the Contractor's responsibility to secure the site during all downtime period, including between the PD test and the start of the full-scale operations.

The owner or operator of any toxic air pollutant emission source subject to the requirements of this Section shall comply with the monitoring, recordkeeping, and reporting requirements in Section .0600 of this Subchapter. History Note: Authority G.S. 143-215.3(a)(l); 143-215.107(a)(4),(5); 143B-282; Eff. May 1, 1990: Amended Eff. April 1, 1999; October 1, 1991 . . 1106 DETERMINATION OF AMBIENT AIR CONCENTRATION (a) Modeling shall not be used for enforcement. Modeling shall be used to determine process operational and air pollution control parameters and emission rates for toxic air pollutants to place in the air quality permit for that facility that will prevent any of the acceptable ambient levels in Rule .1104 of this Section from being exceeded, with such exceptions as may be allowed under 1 SA NCAC 2Q .0700. Enforcing these permit stipulations and conditions shall be the mechanism used to ensure that the requirements of Rule .1104 of this Section, with such exceptions as may be allowed by ISA NCAC 2Q .0700. are met. (b) The owner or operator of the facility may request the Division to perform a modeling analysis of the facility or provide the analysis himself. If the owner or operator of the facility requests the Division to perform the modeling analysis, he shall provide emissions rates, stack parameters, and other information that the Division needs to do the modeling. The data that the owner or operator of the facility provides the Division to use in the model or in deriving the data used in the model shall be the process, operational and air pollution control equipment parameters and emission rates that will be contained in the facility's permit. If the Division's initial review of the modeling request indicates extensive or inappropriate use of state resources or if the Division's modeling analysis fails to show compliance with the acceptable ambient levels in Rule .1104 of this Section, the modeling demonstration becomes the responsibility of the owner or operator of the facility. (c) When the owner or operator of the facility is responsible for providing the modeling demonstration and the data used in the modeling, the owner or operator of the facility shall use in the model or in deriving data used in the model the process operational and air pollution control equipment parameters and emission rates that will be NORTH CAROLINA ADMmISTRA TIVE CODE S 37 D-1100-8 ENR -ENVIRONMENTAL MANAGEMENT 2D .1100 contained in his permit. Sources that are not required to be included in the model will not be included in the permit to emit toxic air pollutants. (d) For the following pollutants, modeled emission rates shall be based on the highest emissions occurring in any single 15 minute period. The resultant modeled 1-hour concentrations shall then be compared to the applicable 1-hour acceptable ambient levels to determine compliance. These pollutants are: (1) acetaldehyde (75-07-0) (2) acetic acid (64-19-7) (3) acrolein (107-02-8) ( 4) ammonia (7664-41-7) (5) bromine (7726-95-6) (6) chlorine (7782-50-5) (7) formaldehyde (50-00-0) (8) hydrogen chloride (7647-01-0) (9) hydrogen fluoride (7664-39-3) (10) nitric acid (7697-37-2) (e) The owner or operator of the facility and the Division may use any model allowed by 40 CFR 51.166(1) provided that the model is appropriate for the facility being modeled. The owner or operator or the Division may use a model other than one allowed by 40 CFR 51.166(1) provided that the Director determines that the model is equivalent to the model allowed by 40 CFR 51.166(1). Regardless of model used, the owner or operator and the Division shall model for cavity effects and shall comply with the modeling requirements for stack height set out in Rule .0533 of this Subchapter. (t) Ambient air concentrations are to be evaluated for annual periods over a calendar year, for 24-hour periods from midnight to midnight, and for one-hour periods beginning on the hour. (g) The owner or operator of the facility shall identify each toxic air pollutant emitted and its corresponding emission rate using mass balancing analysis, source testing, or other methods that the Director may approve as providing an equivalently accurate estimate of the emission rate. (h) The owner or operator of the facility shall submit a modeling plan to the Director and shall have received approval of that plan from the Director before submitting a modeling demonstration to the Director. The modeling plan shall include: (1) a diagram of the plant site, including locations of all stacks and associated buildings; (2) on-site building dimensions; NORTH CAROLINA ADMINISTRATIVE CODE S 37 D-1100-9 ENR -ENVIRONMENT AL MA.l\lAGEMENT 2D .1100 (3) a diagram showing property boundaries, including a scale, key and north indicator; (4) the location of the site on a United States Geological Survey (USGS) map; (5) discussion of good engineering stack height and building wake effects for each stack; (6) discussion of cavity calculations, impact on rolling and complex terrain, building wake effects, and urban/rural considerations; (7) discussion of reasons for model selection; (8) discussion of meteorological data to be used; (9) discussion of sources emitting the pollutant that are not to be included in the model with an explanation of why they are being excluded (i.e . why the source will not affect the modeling analysis); and (1 O) any other pertinent information.

(ETG) has received a contract from the State of North Carolina to prepare the Phase III final design report and develop a set of final plans and specifications for the detoxification of the Warren County PCB Landfill (landfill). The State of North Carolina legislature has passed a bill requiring the utilization of Base- Catalyzed Decomposition (BCD) technology for detoxification of the landfill. The bill also specifies the soil treatment standards required for the detoxification of the landfill. Remedial actions at the landfill consist of detoxification of approximately 60,000 tons of materials contaminated with polychlorinated biphenyls (PCBs). The detoxified soil will be placed on-site after analytical testing has confirmed that the soil has been treated to the standards established in the legislation for the project. Air monitoring is critical to the success of this environmental project. The air monitoring will ensure that the following objectives are accomplished: • Demonstrate protection of human health (on-site and off-site) and the surrounding environment. • Demonstrate compliance with emission limits established for the project and the requirements contained in the State of North Carolina Administrative Code. The pertinent sections are included in Appendix I. • Minimize the release of dust from excavation and earth moving activities. • Determine the concentration of specific contaminants in work areas. This Air Monitoring Plan (AMP) discusses the monitoring requirements for soil excavation, Performance Demonstration Plan (PDP) testing, and full-scale operation of the BCD system. The BCD system will include the following: • One continuous solid phase BCD/thermal desorption unit (CBCD), • One solid phase BCD/batch thermal desorption unit (BBCD), • Two air pollution control systems or vapor recovery systems (VRS), • Process Condensate Separation and Aqueous Phase Treatment System, and • One liquid phase BCD detoxification system (LBCD). There will be a separate system to treat contaminated storm/decontamination/excavation water. The BCD process will be designed to recycle the treated process water to cool and rehydrate the treated soils. The treated storm/decontamination water will be utilized to the extent feasible for dust control and in the BCD process. The purpose of the Air Monitoring Plan is to describe the equipment, procedures and analytical testing utilized for perimeter air monitoring, start-up monitoring, stack gas monitoring and personnel monitoring to ensure that the objectives stated above are met. This AMP includes the following sections: • Section 2 describes the equipment required for the measurement and recording of real-time air monitoring data. ETG Environmental, Inc / BF A Environmental Consultants 1 Final March 2000 Air Monitoring Plan Warren County PCB Landfill • Section 3 describes the actual air monitoring plans for the project. • Section 4 describes the general personnel monitoring. More specific personnel monitoring information is contained in the Health and Safety Plan (HASP). The site Health and Safety Officer (HSO) or his/her qualified representative will be responsible for air monitoring. Air monitoring personnel will be trained by the HSO in proper instrument use, action le vels. care and calibration. ETG Environmental, Inc / BF A Environmental Consultants 2 Final March 2000 Air Monitoring Plan Warren County PCB Landfill · 2.0 DIRECT READING MONITORING INSTRUMENTS Direct reading instruments provide information at the time of sampling. They supply the site supervisory personnel with the instantaneous data needed to make worker safety and process operation decisions. Overall, the instruments provide the user the capability to determine if site personnel or off-site areas are being exposed to concentrations which exceed exposure limits or actions levels for hazardous materials. Several types of direct reading instruments will be used at the work site. Additional information about each instrument is provided in the HASP. 2.1 Flame Ionization Detector/ Photoionization Detector Real-time organic vapor measurements will be made using a Foxboro organic vapor analyzer with a flame ionization detector, an HNu photoionization detector, or their equivalents. The instrument will be calibrated to read in ppm of benzene. The readings from these instruments will be compared with the action levels developed in the HASP for worker protection and with the action limits discussed later in this document. 2.2 Particulate Monitor Real-time dust monitoring will be performed using a direct reading, hand-held, aerosol monitor. A PDM-3 particular monitor or equivalent will be used. Readings will be measured in the employees breathing zone. The instrument will provide data on total and respirable particulate ( dust) in the air. 2.3 Combustible Gas Indicator / Oxygen Meter Combustible gas indicators /oxygen monitors are used to monitor the lower explosive limit and the percent oxygen concentrations. An Industrial Scientific TMX412 combustible gas indicator/oxygen meter or equivalent will be used. These instruments will be used during hot work and confined space entries. The HASP contains additional information on hot work and confined space entries. 2.4 Calibration and Maintenance of Monitoring Equipment Direct reading instruments require charging and cleaning to ensure that they are functioning properly. Equipment will be response checked daily and calibrated per the manufacturer's recommendations. Logs for each instrument will be kept on-site. Additional information on calibration and care of monitoring equipment is contained in the HASP. The HSO will be responsible for training personnel in the proper calibration, use and maintenance of equipment. ETG Environmental, Inc / BF A Environmental Consultants 3 Final March 2000 Air Monitoring Plan Warren County PCB Landfill 2.5 Data Collection and Recording A consistent methodology will be used to collect real-time air measurements. At each monitoring location, the instrument's measurements will be observed for a minimum of ten seconds. If readings are consistent and well below the action level, the operator will record the reading and move to the next monitoring area. If the readings vary considerably or approach the action level, sustained monitoring will take place. For each sustained monitoring event, 20 readings at 15-second intervals will be recorded over a five-minute span. All readings will be averaged at the end of the span and the result recorded on the monitoring form . If the average sustained reading approaches the action level, more frequent monitoring will be scheduled. If the average sustained reading exceeds the action level, the HSO will be notified immediately. Initial monitoring frequency will vary in each work area and with the phase of site-work. Refer to Section 3 of this plan for area specific information. All real-time monitoring data will be recorded on a specific form in the field. These forms will be kept on-site in an air monitoring logbook and organized chronologically. Monitoring data, including date and time of monitoring, instrument reading(s), and person's initials, will be recorded on the form. General weather information (i.e. temperature and relative humidity) that may impact air monitoring will also be included on the form. Examples of an air monitoring data form and calibration log are provided in Appendix II. Real-time monitoring results will be available on-site at all times for review by the appropriate parties. ETG Environmental, Inc / BF A Environmental Consultants 4 Final March 2000 Air Monitoring Plan Warren County PCB Landfill 3.0 SITE AIR MONITORING AND SAMPLING Site investigations have provided information on the hazardous compounds that have been previously identified at the site. Appendix III lists these compounds along with their physical properties and exposure limits. The data from the prior investigations, along with discussions with site representatives, is the basis for the air monitoring and sampling activities proposed in this section. Appendix III also presents calculations performed to determine the hazard level of soil PCB and Dioxin contamination as respirable dust. Maximum soil concentrations from previous analytical data were converted into the personnel exposure limit and compared to the dust exposure action level. The resultant personnel exposure limit level was 14 7 mg/m3, much higher than the dust action level of 5 mg/m3. 3.1 Background Monitoring The accumulation of background information on air quality at the site is critical to the process of developing an air monitoring plan. Background air monitoring data will be compared against operational air monitoring data to determine the impact of the detoxification activities on air quality. 3.1.1 Wind Speed and Direction Prevailing wind direction and wind speed information has been downloaded via Windrose from the Internet for the years 1984 to 1992 (the most recent available data). The Raleigh-Durham airport is the representative wind data location for the site. The prevailing wind direction is from southwest to northeast (32% of the time). The secondary wind direction is from northeast to southwest (24%), directly opposite of the predominant, prevailing winds. Most frequent wind speeds are from 4-10 miles per hour. Calm winds occur 7% of the time. Windrose data is presented in Appendix IV. The prevailing wind direction data has been used to locate the permanent air sampling locations. Drawing 102 locates these air sampling points and identifies the prevailing wind direction. 3.1.2 Meteorological Station A meteorological station will be located on-site to monitor temperature, barometric pressure, relative humidity, wind speed, wind direction and precipitation. The data collected from the station will be recorded daily in the logbook. The daily wind direction will determine the up-and downwind locations for real-time air monitoring. ETG Environmental, Inc / BF A Environmental Consultants 5 Final March 2000 Air Monitoring Plan Warren County PCB Landfill 3.1.3 Base Line Monitoring Prior to any site work, baseline air monitoring will be performed. Real-time organic vapor and dust monitoring equipment will establish the pre-existing levels for these constituents. Air samples upwind and downwind of the work areas will be collected and submitted to a laboratory for PCBs, Dioxin/Furans, Volatile Organic Compounds (VOCs) and dust analysis. This information will form the background data against which operational air monitoring results will be compared. Air samples to be analyzed for VOCs will be collected using SUMMA canisters. SUMMA canisters are vacuum tanks that use a regulator to collect a preset volume of air over a 24-hour period. The canister is then sent to a laboratory for analysis. Air samples to be analyzed for PCB and Dioxin/Furans will be collected using polyurethane foam (PUF) organic toxic samplers. These samplers extract a preset volume of air through a pol yurethane foam cartridge that is sent to a laboratory for analysis. Quantitative dust samples can be collected on a filter cartridge using a total suspended particulate (TSP) sampler which is sent to a laboratory for analysis. The PUF samplers and TSP samplers require permanent power to operate continuously for extended periods. These units will be used in remote locations at the state perimeter boundary, requiring that pre-set locations with electrical power be established. This limits the ability to monitor changing locations due to changing wind directions. See Table 3-2 for a listing of the analytical methods to be used to analyze the base line samples. 3.1.4 Sample Tracking All air emission samples collected will be tracked using Chain of Custody Records in compliance with United States Environmental Protection Agency (USEP A) procedures. 3.2 Construction Monitoring During the equipment mobilization and set-up phase, prior to any excavation, daily monitoring will be performed. Real-time organic vapor and dust monitoring equipment will measure dust and particulate levels within and outside of the work areas. Results will be compared against the Action Levels that are presented in Table 3-1. As discussed previously, direct readings that approach or exceed the action levels will result in additional monitoring or other remedial activities.

Particulate Readings: Real time readings will be averaged as described above, an upgrade will be implemented if two consecutive periods exceed a particular action level. Organic vapor meter should be calibrated to benzene equivalents. "Units" are indicated as prescribed by the specific direct reading instrument. This lattice is designed to correlate integrated sample results with real time/direct readings, to allow for timely and effective decisions to be made with regard to personal protective equipment and respiratory protection. Organic Vapors Readings: (I) To be used to determine sustained readings if instantaneous readings approach Action Limit. Sustained monitoring period consists of 20 readings taken every 15 seconds. All readings will be averaged at the end of the monitoring period. Two consecutive sustained monitoring periods warrant corrective action. Engineering controls may be used at any time to control emissions.

ETG Environmental, Inc / BF A Environmental Consultants 13 Final March 2000 Air Monitoring Plan Warren County PCB Landfill· 3.3 Landfill Excavation Excavation activities will take place during daylight hours for one, eight to ten hour, shift per day. It is anticipated that excavation will take place five days per week; this will vary with workload and weather requirements. The HSO will monitor airborne emissions and operator exposures during excavation activities. Emissions will be monitored in the landfill work area and up-and downwind from the excavation. Direct reading instruments will monitor for respirable dust and for VOCs at least twice per shift. During the first few weeks of excavation, periodic personnel samples will be collected and submitted for laboratory analysis (see the HASP). This sampling will occur concurrent with the excavation of PCB contaminated soils. 3.4 BCD Processing Area Several varied activities will occur in the BCD processing area. On the north end, soil screening, mixing and stockpiling will take place. The screening and mixing activities will be intermittent -three to six hours per day and approximately five days per week. Soil stockpiles will be maintained continuously. The batch and continuous BCD treatment equipment and the liquid BCD processing equipment will be located in the central area. This work area will be active 24 hours per day, seven days per week. Clean soil stockpiles awaiting final laboratory confirmation will be located along the south area. Clean soil stockpiles will be maintained continuously. Refer to Drawing 101 for the work area layout. Access to the BCD area will be limited to those trained and certified per the HASP. The HSO will monitor the airborne emissions and personnel exposures during all work shifts within and downwind of the BCD processing area. Direct reading instruments will monitor for VOCs at a minimum of twice per shift. Dust monitoring will occur concurrent with screening and stockpiling activities. 3.5 Stack Emission Monitoring and Stack Testing In addition to the process area monitoring, continuous process stack monitoring will be conducted. The monitoring points will be located at the discharge of the flameless thermal oxidizers (FTO) for both vapor recovery systems. Stack emission monitoring provides total hydrocarbon (THC) readings using the THC analyzer. The analyzer package will be capable of sample extraction, filtration and delivery to analyzer. The unit will operate unattended, including calibration gas sequencing and local data collection. The data collection computer will receive process concentration and calibration data from the analyzer, archive the data and generate the required reports. Local computer software will review the collected data and alert operators of any emission exceedance. Real-time stack emissions data can be accessed/viewed by site personnel using the same software. ETG Environmental, Inc / BF A Environmental Consultants 14 Final March 2000 Air Monitoring Plan Warren County PCB Landfill 3.5.1 Stack Testing Stack emission tests will be conducted during the PDP testing to verify that CBCD and BBCD emissions do not exceed established project requirements. A qualified stack-testing contractor will conduct all stack tests. The Contractor, with the assistance of the stack testing contractor will need to execute and submit to the NCDENR, Division Of Air Quality (DAQ) a Source Test Notification Form. A Source Test Notification Form is contained in Appendix V. The Source Test Notification Form provides the DAQ with necessary information to determine potential problem areas related to a proposed source-testing project prior to the actual test date. The primary goals of the Source Test Notification Form are to initiate communication between representatives of the permitted facility, the testing consultant and the DAQ and to identify and resolve any specific testing concerns prior to testing. Specifically, where modifications to standard test methods maybe required due to configuration of the stacks and/or stack emission airflow's, the modification and procedures can be discussed and approved prior to stack testing. The executed form should be issued at least 45 days prior to testing. During each of the three performances test runs, two stacks, one each for the CBCD and BBCD will be tested. The stack sampling will occur at the discharge of the CBCD-VRS and BBCD-VRS. Unlike continuous process stack monitoring, the stack testing will monitor for a wide range of constituents including: VOCs, PCBs, Dioxins/Furans, Semi- volatiles, Metals, HCl, and Particulate. Table 3-2 provides a list of the quantitative stack sampling. The Environmental Protection Agency (EPA) has created reference methodologies, which are included in 40 CFR 60 Appendix A or in SW-846 (EPA's Test Methods for Evaluating Solid Waste). Each methodology sets the sampling protocol used by the stack testing contractor. Below summarizes the EPA Methodologies related to this site-work: • VOCs -EPA Method SW-846 0030 (VOST) • PCB's -EPA Method 23 • Dioxins/Furans -EPA Method 23 • Semivolatiles -EPA Method SW-846 0010 • Metals -EPA Method 29 • HCl -EPA Method 26 (non-isokinetic) or 26A (isokinetic) • Particulate -EPA Method 5 ( total particulate) or 201 A (PM 1 o particulate) • THCs -EPA Method 25A Temperature-EPA Method 4 3.5.2 General Stack Sampling Procedures: Each test for the individual classes of target materials will consist of three sampling runs on each of the two stacks utilizing the equipment specified in the ETG Environmental, Inc I BF A Environmental Consultants 15 Final March 2000 Air Monitoring Plan Warren County PCB Landfill sampling methods (e.g., isokinetic sampling trains, continuous emissions monitors [CEMS], proportional sampling trains). Sampling traverse point locations will be determined by the use of EPA Method 1. Stack velocity and volumetric flowrate determinations will utilize EPA Method 2. Stack gas dry molecular weight and moisture will be determined by EPA Methods 3 and 4. The duration of the sampling runs will be determined in one of several ways. Run duration is defined in some sampling methods ( e.g., EPA Method 0030). Other methods may require the calculation of run duration based upon analytical quantification limits and sampling rate ( e.g., EPA Method 23). The duration of other sampling runs may be determined by or in consultation with North Carolina Department Environment and Natural Resources (NCDENR) in order to insure adequate sample volumes for target material quantification. Sampling will be performed isokinetically where required ( e.g., EPA Method 5 for particulate). All analytical procedures will be those specified in the individual sampling methods. Sample maximum hold times will be adhered to and all samples will be subject (in transit to laboratories) to custody and security procedures that will insure accurate sample analysis. 3.5.3 Stack Sampling Data The stack sampling data collected during the PD tests will be compared to the allowable stack emissions determined by the air dispersion modeling. NCDENR has provided health based standards for allowable concentrations at the property line. The air dispersion modeling will be used to convert allowable property line concentrations to allowable stack emissions. Appendix H of the PDP provides an explanation of the model (Screen3) including example inputs and resultant stack emission limits, and the NCDENR Air Emission Standards are included as Appendix I of this plan. 3.6 Perimeter Area The site perimeter has been established at the state property boundary. During all operations, the HSO or his/her representative will monitor the airborne emissions at least twice per shift, adjacent to the perimeter, at one upwind and two downwind locations. Direct reading instruments will monitor for VOCs and respirable dust. Additional quantitative monitoring will take place during the PD and early phases of work. See Table 3-2 for a summary of the sampling plan. Initially, two downwind and one upwind PCB, VOC, Dioxin/Furan and particulate air samples will be collected for laboratory analysis on a daily basis. Drawing 102 shows the proposed perimeter sampling locations based upon prevailing wind direction and soil treatment area. The frequency and numbers of samples collected will decrease as site work continues ( assuming earlier ETG Environmental, Inc / BF A Environmental Consultants 16 Final March 2000 Air Monitoring Plan Warren County PCB Landfill analysis proves low or no levels of constituents). PCB and Dioxin/Furan monitoring will be conducted on a time-weighted basis using PUF samples. VOC samples will be collected using SUMMA canisters. Particulate monitoring will target the respirable dust fraction (i.e. particles less than 10 microns in size) of total dust generated. Particulate will be monitored at each sampling location using a PDM-3 and in several locations using a TSP sampler. 3. 7 Engineering Controls Appropriate engineering controls will be instituted to reduce emissions in the event the action level is exceeded during remedial activities. Examples of engineering controls for dust control include spraying of water or chemicals, covering sources of dust, and reducing vehicle speeds on access roads or speed of excavation. Examples of engineering controls for VOCs include spraying stockpiles with foam or covering stockpiles with plastic sheeting or other barriers. ETG Environmental, Inc I BF A Environmental Consultants 17 Final March 2000 Air Monitoring Plan Warren County PCB Landfill 4.0 PERSONNEL MONITORING AND SAMPLING The Site's Health and Safety Plan provides detailed information on the personnel monitoring planned during each phase of site work. Table 4-1, summarizes the personnel monitoring and sampling plan. 4.1 Site Air Monitoring and Sampling Program The sampling and analysis will focus on PCBs, dioxin/Furans, organics and particulates/dust. The analytical results will be compared to the contaminant work zone action level lattice. Based upon the analytical results a sampling program will be finalized for the full-scale project. In addition, further engineering controls may be instituted to reduce airborne contaminants. Table 4-1 Personnel Monitoring and Sampling Summary depicts the site personal air monitoring and sampling program for the site. Periodically, minimally twice per shift, all operational areas will be surveyed to measure respirable dust levels during on-site activities, the HSO will monitor the work area with real time instruments. Air monitoring shall focus in the worker's breathing zone, although source readings may be taken for reference. Monitoring shall be conducted when material handling activities are being performed. Monitoring shall be conducted as frequently as necessary during all initial activities to determine the effectiveness of engineering controls and verify levels of protection. Once activities have been shown to produce consistent air monitoring results, which do not exceed action levels, the frequency of the air monitoring may be reduced at the discretion of the HSO. All instruments utilized shall be response checked daily and calibrated as per manufacturer's recommendations and in accordance with acceptable industrial hygiene protocol. A calibration log shall be kept for each instrument. The HSO shall be responsible for training personnel in the proper use and care of all monitoring instrumentation. 4.2 Integrated Personal Sampling In addition to real time air monitoring during remedial activities, a personal air monitoring program shall provide for the determination of worker's airborne exposure levels to specific contaminants. Such a determination will be made from laboratory analysis of air samples collected from representative workers during an average work shift. The selection of the workers to be monitored for daily exposure shall be done by the HSO based on his professional judgement of the characteristics of the jobs and the locations in each work area, and will be biased toward those workers determined to be highest at risk.

I Final March 2000 Air Monitoring Plan Warren County PCB Landfill Initially, personal air monitoring will be performed on one (1) to two (2) representative employees for three days over the first two (2) weeks of full-scale operations. These samples shall be screened for major contaminants of concern listed in Table 4-1. Screening for these specific contaminants shall take place during any new work phase. The continued sampling strategy shall depend on the results of the initial monitoring. Follow-up worst case samples shall be performed at the discretion of the HSO. If levels above the Action Level are detected, additional air sampling shall be performed. Air samples will be submitted to an AIHA accredited Laboratory for analysis. Personal air sampling results will be used to determine personnel exposure during remedial construction, and will determine if the level of personal protection is adequate for work being performed. Upgrades/down grades in levels of personal protective equipment are based on real-time direct reading instruments and verified by integrated personal sampling. Initial levels shall be established based on prior project experience with similar materials, calculated exposure values based on sample analysis, and real- time readings during sample collection. Calibrated personal air sampling pumps shall be used to draw air through appropriate sampling media in order to collect representative integrated air samples. For assessing employee exposures, sampling media shall be placed in the approximate breathing zone of representative, potentially exposed employees. Employees to be monitored shall be selected based on a worst case sampling strategy, such that those employees with the greatest potential for exposure shall be monitored ETG Environmental, Inc / BF A Environmental Consultants 22 Final March 2000 ~ ,s.~\i ~-----~,o~ ® CONFIDENTIAL -Do not copy or disseminate without prior permission of ETG Environmental, Inc.

The owner or operator of any toxic air pollutant emission source subject to the requirements of this Section shall comply with the monitoring, recordkeeping, and reporting requirements in Section .0600 of this Subchapter. History Note: Authority G.S. 143-215.3(a)(l); 143-215.107(a)(4),(5); 143B-282; Eff. May 1. 1990; Amended Eff. April 1, 1999; October 1, 1991 . . 1106 DETERMINATION OF AMBIENT AIR CONCENTRATION (a) Modeling shall not be used for enforcement. Modeling shall be used to determine process operational and air pollution control parameters and emission rates for toxic air pollutants to place in the air quality permit for that facility that will prevent any of the acceptable ambient levels in Rule .1104 of this Section from being exceeded, with such exceptions as may be allowed under 15A NCAC 2Q .0700. Enforcing these permit stipulations and conditions shall be the mechanism used to ensure that the requirements of Rule .1104 of this Section, with such exceptions as may be allowed by' 1 SA NCAC 2Q .0700, are met. (b) The owner or operator of the facility may request the Division to perform a modeling analysis of the facility or provide the analysis himself. If the owner or operator of the facility requests the Division to perform the modeling analysis, he shall provide emissions rates, stack parameters, and other information that the Division needs to do the modeling. The data that the owner or operator of the facility provides the Division to use in the model or in deriving the data used in the model shall be the process, operational and air pollution control equipment parameters and emission rates that will be contained in the facility's permit. If the Division's initial review of the modeling request indicates extensive or inappropriate use of state resources or if the Division's modeling analysis fails to show compliance with the acceptable ambient levels in Rule .1104 of this Section, the modeling demonstration becomes the responsibility of the owner or operator of the facility. (c) When the owner or operator of the facility is responsible for providing the modeling demonstration and the data used in the modeling, the owner or operator of the facility shall use in the model or in deriving data used in the model the process operational and air pollution control equipment parameters and emission rates that will be NORTH CAROLINA AD~STRATIVE CODE S 37 D-1100-8 ENR · ENVIRONMENTAL MANAGEMENT 2D .1100 contained in his permit. Sources that are not required to be included in the model will not be included in the permit to emit toxic air pollutants. (d) For the following pollutants, modeled emission rates shall be based on the highest emissions occurring in any single 15 minute period. The resultant modeled 1-hour concentrations shall then be compared to the applicable 1-hour acceptable ambient levels to determine compliance. These pollutants are: (1) acetaldehyde (75-07-0) (2) acetic acid (64-19-7) (3) acrolein (107-02-8) (4) ammonia (7664-41-7) (5) bromine (7726-95-6) (6) chlorine (7782-50-5) (7) formaldehyde (50-00-0) (8) hydrogen chloride (7647-01-0) (9) hydrogen fluoride (7664-39-3) (10) nitric acid (7697-37-2) (e) The owner or operator of the facility and the Division may use any model allowed by 40 CFR 51.166(1) provided that the model is appropriate for the facility being modeled. The owner or operator or the Division may use a model other than one allowed by 40 CFR 51.166(1) provided that the Director determines that the model is equivalent to the model allowed by 40 CFR 51.166(1). Regardless of model used, the owner or operator and the Division shall model for cavity effects and shall comply with the modeling requirements for stack height set out in Rule .0533 of this Subchapter. (f) Ambient air concentrations are to be evaluated for annual periods over a calendar year, for 24-hour periods from midnight to midnight, and for one-hour periods beginning on the hour. (g) The owner or operator of the facility shall identify each toxic air pollutant emitted and its corresponding emission rate using mass balancing analysis. source testing. or other methods that the Director may approve as providing an equivalently accurate estimate of the emission rate. (h) The owner or operator of the facility shall submit a modeling plan to the Director and shall have received approval of that plan from the Director before submitting a modeling demonstration to the Director. The modeling plan shall include: (1) a diagram of the plant site, including locations of all stacks and associated buildings; (2) on-site building dimensions: NORTH CAROLINA ADMINISTRATIVE CODE S 37 D-1100-9 ENR-ENVIRONMENTAL MANAGEMENT 2D .1100 (3) a diagram showing property boundaries, including a scale, key and north indicator; (4) the location of the site on a United States Geological Survey (USGS) map; (5) discussion of good engineering stack height and building wake effects for each stack; (6) discussion of cavity calculations, impact on rolling and complex terrain, building wake effects, and urban/rural considerations; (7) discussion of reasons for model selection; (8) discussion of meteorological data to be used; (9) discussion of sources emitting the pollutant that are not to be included in the model with an explanation of why they are being excluded (i.e. why the source will not affect the modeling analysis); and (10) any other pertinent information.

(ETG) has received a contract from the State of North Carolina to prepare the Phase III final design report and develop a set of final design plans and specifications for the detoxification of the Warren County PCB Landfill (Site). The State of North Carolina General Assembly has passed a bill requiring the utilization of Base Catalyzed Decomposition (BCD) technology for detoxification of the landfill. The bill also specifies the material treatment standards required for the detoxification of the landfill. Remedial actions at the landfill consist of detoxification of approximately 60,000 tons of material contaminated with polychlorinated biphenyls (PCBs). The detoxified soils will be placed on-site after analytical testing has confirmed that the material has met the treatment standards established in the legislation for the project. This Final Verification/Confirmation Sampling Plan (FVCSP) discusses the sampling and analytical requirements for material excavation, Performance Demonstration Plan (PDP) testing and full-scale operation of the BCD system. The BCD system will include the following: 1) One continuous solid phase BCD/thermal desorption unit (CBCD), 2) One solid phase BCD/batch thermal desorption unit (BBCD), 3) Two air pollution control systems or vapor recovery systems (VRS), one each for the CBCD (CBCD-VRS) and BBCD (BBCD-VRS), and 4) Process condensate separation and aqueous phase treatment system (PCSAPT), and 5) One liquid phase BCD detoxification system (LBCD). Included in the PDP will be requirements for the on-site treatment system for condensate produced from the CBCD-VRS and BBCD-VRS systems. There will be requirements for a separate treatment system to treat storm water run-off from the contaminated areas of the landfill. The BCD process will be designed to utilize the treated process water to cool and rehydrate the treated materials. The operation plan will be designed to utilize treated stormwater/decontamination water for dust control and for use in the BCD process. The PDP will also address requirements for the CBCD-VRS and BBCD-VRS. Requirements for air monitoring and sampling are not included in this Plan. The personnel monitoring, sampling and analytical, methodologies and requirements are contained in the Health and Safety Plan. The stack testing requirements are contained in the Performance Demonstration Plan. Perimeter and work zone monitoring, sampling and analytical, requirements and methodologies are contained in the Air Monitoring Plan. 1.1 Site History/Description The Warren County PCB Landfill is located in Warren County, North Carolina, and approximately 50 miles north of Raleigh, North Carolina. The Site is situated within a tract of land owned by the State of North Carolina that covers 19.317 acres. The Site includes a 2.54-acre landfill cell (PCB Landfill) that contains materials with elevated ETG Environmental, Inc / BF A Environmental Consultants 1 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill . levels of polychlorinated biphenyls (PCBs) and dioxins/furans. Approximately half of the remaining State property is undisturbed with moderately dense population of trees approximately 30 feet in height. A gravel road approximately 3,000 feet long provides access to the Site from State Route 1604. A site map is included in the bid specification drawings. The PCB Landfill is approximately 250 feet wide (measured in an east to west direction) and 500 feet long. Approximately 40,000 cubic yards of soils were deposited into the Landfill from the remediation of roadways throughout the State that were illegally sprayed with PCB oils to avoid proper disposal of the oils under Toxic Substance Control Act (TSCA). Approximately ten percent of the soils originated from the Fort Bragg Military Reservation near Southern Pines, North Carolina and are assumed to be of a similar nature to the balance of the contaminated soils. The PCB concentrations in the soil ranged from 259 parts per million (ppm) to a high of 853 ppm, with an average concentration of 500 ppm. Dioxin/furan concentrations ranged from 147 parts per trillion (ppt) [toxicity equivalent concentrations (TEQ)] to 238 ppt, with an average concentration of 200 ppt TEQ. This data has been reported in the Phase I Base Catalyzed Decomposition study, and is included as part of the bid specification. The maximum depth of the PCB Landfill at the center is approximately 36 feet, which includes the lower liner and existing cover. The depth at the perimeter is approximately 20 feet. The existing ground surface of the contiguous area begins at the same elevation as the perimeter of the PCB Landfill. In addition to the PCB-contaminated soils, a relatively small quantity of cement kiln dust (less than 2-percent of the total volume) occupies the northeast comer of the PCB Landfill. Approximately one-half of the PCB Landfill rises above the existing ground surface. The PCB Landfill was completed in 1983. Included, as part of the bid specifications is an Appendix titled, PCB Waste Disposal Site, Warren County that contains the as-built drawings for the landfill. As shown on the drawings the landfill was constructed as follows from top to bottom: 1' Top Soil 1' Fill for bridging and Liner Protection 10 Mil PVC Liner 2' Clay Liner 1' Fill for bridging 0' -24' PCB-contaminated Soils Filter Fabric 9" Sand for Leachate Collection System 5' Clay Liner 30 Mil PVC Liner 1' Fill for bridging and Liner Protection 9" Sand ETG Environmental, Inc / BF A Environmental Consultants 2 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill The bottom of the landfill is sloped from south to north and west to east at 2% grade. A single sump was installed in the northeast comer of the landfill approximately one foot in depth into the five-foot thick clay liner. A single polyvinyl chlorinated (PVC) collection pipe was installed from the sump extending through the surface of the landfill. A pneumatic positive displacement pump was placed into the sump and leachate from the landfill has been pumped from the sump through a sand filter and carbon system located at the northern end of the landfill. During evaluation of the potential detoxification technologies, the primary objective was to utilize a process that actually destroyed PCBs and dioxin/furans in a non-incineration manner. The BCD process utilizes chemical destruction to achieve this objective. The BCD process is a chemical reaction that destroys PCBs and dioxins/furans by removing the chlorine atom from the chlorinated compound and replacing it with hydrogen, thus rendering the molecule to a non-hazardous compound. The process is conducted in both the solid and liquid phase. ETG Environmental, Inc / BF A Environmental Consultants 3 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill 2.0 SCOPE AND OBJECTIVES This plan addresses sampling and analysis required during Performance Demonstration (PD) testing and full-scale operation. The activities generating work under this plan are summarized below. Air Monitoring: Upwind and downwind pre-established monitoring stations equipped with electrical power will be selected based upon historical predominant wind directions to monitor PCBs, dioxin/furans, volatile organic compounds (VOCs) and particulates periodically at the State boundary (see Air Monitoring Plan). Prior to remedial activities, baseline air monitoring will be conducted to establish background site conditions. Perimeter monitoring will be conducted during remedial activities to demonstrate the adequacy of engineering controls designed to maintain ambient air quality standards. Excavation Activities: Materials that exhibit contaminant concentrations in excess of the cleanup criteria of 200 ppb PCBs and 200 ppt TEQ dioxins will be excavated for on-site treatment. Excavation limits will be determined in the field based upon verification sampling with on-site screening (immunoassay testing) and confirmation sampling with off-site laboratory analysis. • BCD Process System: Excavated materials containing contamination concentrations in excess of treated cleanup criteria will be treated by the BCD process system, which includes the following: • Certified weigh scale for process tonnage verification, • Screening materials through a 2" by 2" screen, • Blending BCD reagents into the screened material, • Treating the materials on-site through either the CBCD or the BBCD, • Off-gases generated from the CBCD and BBCD will be treated through their respective vapor recovery systems (CBCD-VRS and BBCD-VRS), • Process stream generated by the condensing of vapors and removal of particulates from the CBCD-VRS and BBCD-VRS will be filtered, • Filtrate from the process condensate physical separation system will be treated in the aqueous phase treatment system, • Effluent from the aqueous phase treatment will be used for rehydration of treated materials and/or makeup water for the BCD process system, • Filter cake produced from the process condensate separation system will be treated, if required, in the BBCD or the LBCD system, • Organics collected from the process condensate separation system will be treated, if required, in the LBCD system, and • Treated organics will be disposed off-site at a disposal facility and treated materials will be backfilled on-site. Performance Demonstration (PD): The PD test will be conducted to verify the capability of the CBCD and BBCD systems to meet the cleanup standards for the material. Stack sampling will be conducted to ensure that CBCD-VRS and BBCD-VRS ETG Environmental, Inc / BF A Environmental Consultants 4 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill stack em1ss1ons are compliant with North Carolina State air em1ss1on requirements. Perimeter monitoring will be conducted to evaluate impact on ambient air quality. The PCSAPT and LBCD system effluents will be sampled and analyzed to verify they meet their respective performance criteria. Storm Water/Decontamination Water Treatment: Potentially contaminated storm water, decontamination water and water from dewatering activities in the landfill will be pumped to a lined pond. The water from the lined pond will be treated using a sand filter followed by carbon polishing. The treated water will be pumped to the existing unlined pond. It can then be used for dust control and/or BCD process make-up. Sampling and analysis of the treated water being discharged to the existing pond will be performed to confirm compliance with the Spray Irrigation System permit. Decontaminated Materials/Off-Site Disposal: Construction equipment, decontaminated process equipment, and associated pads and structures will come into contact with potentially contaminated materials. The equipment and areas will require decontaminating following the procedures set forth in 40 CFR 761.360 -761.378 prior to demobilizing from site. The goal of the project is to treat all contaminated materials on-site. However, there will be residual materials that will not be able to be treated, due to the physical/chemical characteristics or the completion of the processing, that will require off-site disposal. Sampling and analytical procedures must comply with 40 CFR 761. Groundwater Sampling: Monitoring wells exist on the site which are sampled semi- annually by the NCDENR. NCDENR personnel will continue to perform the required sampling and analysis, and this work will not be part of the scope of work for this project. ETG Environmental, Inc / BF A Environmental Consultants 5 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill 3.0 SAMPLING AND ANALYTICAL REQUIREMENTS This section describes the field sampling and analytical procedures required for the project, excluding the air monitoring requirements, which are found in the Air Monitoring Plan, Health and Safety Plan, and Performance Demonstration Plan. This Plan describes four categories of samples to be collected and analyzed for this project: 1) Verification Samples: Verification samples will be collected and analyzed in the field to provide the site management with information to make daily operational decisions. Examples of these tests are PCB Immunoassay, percent moisture, and pH. Verification samples can never serve the dual purpose as Control samples ( defined below). 2) Confirmation Samples: Confirmation samples will be analyzed by a laboratory certified to perform the applicable parameters under either North Carolina Administrative Code (NCAC) Subchapter 2H.0800, or the Environmental Protection Agency's (EPA) Contract Laboratory Program (CLP). Unless otherwise noted in this Plan, field procedures must be in compliance with the May 1996 US EPA Region IV Environmental Investigations Standard Operating Procedures and Quality Assurance Manual (SOP). Field procedures include, but are not limited to, proper chain of custody protocols, sampling methods, preservation, containerization, field blanks, duplicates, matrix and matrix spikes and shipping procedures. 3) Informational Samples: Informational samples can be analyzed either through field screening methods or the use of laboratory analysis. The designation "informational" means that the sample is not a regulatory or permitted sample/ discharge parameter. The informational samples are generally influent or intermediate process samples to determine the effectiveness of a process system or components of a process system. These samples allow the Contractor to monitor and adjust the effectiveness of the process system. The Contractor may desire to collect samples from additional locations or increase frequency of an informational sample location, as they deem appropriate. However, the Contractor will not be compensated by NCDENR for additional information samples collected and analyzed. 4) Control Samples: Control samples are collected at points of discharge (regulatory or required by permit). Only certified laboratories can analyze control samples, as these are considered confirmation samples. The sampling frequency of control samples shall not be decreased without the approval of the State and regulatory agency. As with confirmation samples, field procedures must be compliant with the EPA Region IV Environmental Investigations Standard Operating Procedures and Quality Assurance Manual (SOP). Table 3-1 provides the sampling location, frequency, quality control requirements, type of sample, data use (informational or control), analysis and minimum estimated samples for the full-scale operations. The following sections describe each sample area. ETG Environmental, Inc / BF A Environmental Consultants 6 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill 3.1 Untreated Materials Untreated materials will be sampled and analyzed during three phases of the project: • Performance Demonstration, • Excavation Activities, and • Post Excavation. 3.1.1 Performance Demonstration (PD) Sampling Untreated Materials Samples collected during the PD are to provide a baseline of the material contaminants and concentrations. The analysis will provide information on the PCB and dioxins/furans concentrations prior to treatment. The materials must contain sufficient PCB concentrations to properly demonstrate the CBCD and BBCD treatment process for full-scale operation, and to obtain approval by TSCA and the state to operate the BCD treatment system for the range of PCBs concentrations anticipated for this project (200 ppm to 900 ppm). If the materials excavated for the PD are not sufficiently concentrated with PCBs, the materials will require to be spiked with PCBs. In addition to the PCB and dioxins/furans analysis, untreated materials will be analyzed as indicated in the PDP. A stockpile of PCB-contaminated material, screened and blended with BCD additives will be prepared for each day's PD test, for a total of six stockpiles for the duration of the performance demonstration testing. Eight grab samples will be collected from each stockpile and then composited into one sample. A portion of the sample will be screened for PCBs using an immunoassay PCB test and analyzed for percent moisture. The remainder of the sample will be sent to a laboratory and analyzed for PCBs, dioxin/furans, semi-volatile organic compounds (SVOCs), total chlorides, metals, percent moisture and density. Four grab samples will be collected from each stockpile and sent to a laboratory and analyzed for VOCs. The purpose of these analyses is to fully characterize the materials to be treated. For more information regarding the performance demonstration sampling see the Performance Demonstration Plan. 3.1.2 Excavation Sampling Untreated Materials During full-scale operations, samples of the untreated material will be collected everyday of excavation activities. A daily composite sample will be generated by randomly sampling the material from the trucks transporting the excavated material to the soil preparation area. These samples, referred to as informational samples in Table 3-1, are for segregating the excavated materials prior to treatment through the CBCD or the BBCD. The following guideline will apply: ETG Environmental, Inc / BF A Environmental Consultants 7 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill • BBCD-Untreated material with a PCB concentration of 750 ppm or greater, or a percent moisture content of 15 percent or greater; • All other untreated materials to either the CBCD or BBCD. 3.1.3 Post Excavation Sampling Untreated Soils Verification and confirmation samples will be collected from the sidewalls and floor of the excavated landfill. Excavation will continue until the PCB- contaminated materials, the filter fabric and six-inches of the five-foot thick clay liner are removed. The Contractor will design a sampling grid over the base and sidewalls of the excavation. Grid nodes will not be greater than 50 feet apart. At each grid node, collect a sample from 0-3 inches into the base or sidewall. The Contractor may opt to collect up to five samples from each grid node and composite the samples into one composite sample. The Contractor will screen a portion of the sample representing the grid node and analyze the sample in the field for PCBs using an immunoassay test kit. This sample is referred to as a verification sample, and provides expedited information to the Contractor whether to cease excavation, or continue another six -inches in depth. If the verification sample results indicate the sample is at or below the cleanup standard of 200 ppb, then the remaining sample will be submitted as a confirmation sample to an approved laboratory for PCB analysis. Excavation will be complete when the confirmation sample results are below the cleanup standard. Excavation will continue in six-inch increments in depth until the cleanup standard is achieved. A portion of the sediments located in the existing pond have been tested and determined to contain levels of PCBs above the cleanup standard of 200 ppb. The affected area extends from the discharge pipe of the existing water treatment system and proceeds toward the center of the pond. The sediments will be excavated from the pond and post excavation samples will be collected and analyzed in the field using the PCB immunoassay test (verification) and then submitted to a laboratory for PCBs ( confirmation). At a minimum, three sediment samples will be collected to verify/confirm the remaining sediments are at or below the PCB cleanup standard of 200 ppb. 3.2 Treated Materials Treated soils will be sampled and analyzed during three phases of the project: • Performance Demonstration • First Two Weeks Of Full-scale Operations, and • Remainder Of Project. The sampling locations, frequency and parameters are different for all three phases. The sampling schedule for the PD is to demonstrate the operation of the system to the regulatory agencies in order to obtain the necessary permits.

The sampling schedule for the first two weeks has been designed to confirm. The majority of the sampling and analysis results collected for the PD. Assuming, the first two weeks of full-scale operations demonstrate consistent results to those collected in the PD, through a reduced sampling schedule has been proposed for the remainder of the project. Upsets to the operation of the system and/or non-compliance sample results will require a more stringent sampling schedule. 3.2.1 Performance Demonstration (PD) Sampling Treated Materials Treated samples will be collected from each PD test. Materials treated in the CBCD will be stockpiled into four distinct piles for each performance demonstration test. Two samples from each soil pile will be collected, for a total of eight samples. The eight samples will be composited into one sample and sent to a laboratory for PCB, dioxin/furans, SVOCs, total chlorides, metals, percent moisture, density, ignitability and corrosivity. One grab sample will be collected from two of the four stockpiles and analyzed for VOCs. Materials treated through the BBCD will be staged in one stockpile. Eight samples will be collected and then composited into one sample and analyzed for the same parameters for the treated CBCD materials. Two grab samples will be collected from the stockpile and analyzed for VOCs. The analytical results will confirm the treated materials meet the soil cleanup criteria for this project, and al so that the treated materials are not hazardous for other constituents. NOTE:there was no indication during any of the previous phases of the project that the treated materials would be hazardous for other constituents, this is solely being conducted as a confirmation. 3.2.2 First Two Weeks Full-scale Operations Sampling Treated Materials The sampling plan for treated materials is predicated on the successful completion of the performance demonstration test and that no other contaminants of concern were identified. Treated materials from the CBCD and BBCD will be separated into distinct stockpiles. Each CBCD stockpile will contain two days of processed material and each BBCD stockpile will contain one week of processed material. Eight grab samples will be collected from each two-day stockpile. The eight samples will be composited into one composite sample for each stockpile. The samples will be sent to a laboratory for PCBs and dioxin/furans analysis. An expedited analytical tum around time will be requested so analytical results for the first samples are received before the two-week full-scale operation period is concluded. ETG Environmental, Inc / BF A Environmental Consultants 13 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill 3.2.3 Remainder Full-scale Operations Sampling Treated Material Treated materials from the CBCD will continue to be grouped in two-day stockpiles. The sampling protocol will remain the same, with eight grab samples collected per stockpile and then composited into one sample. A laboratory will analyze the sample for PCBs. A monthly stockpile will be generated of materials treated in the BBCD unit or one sample per batch for materials treated with an initial PCB concentration greater than 750 ppm. Eight grab samples will be collected from the monthly stockpile and composited into one sample. Similarly, each batch stockpile treated from materials containing PCBs greater than 750 ppm will have eight grab samples collected and composited into one sample. The samples will be sent to a laboratory for PCBs and dioxin/furans analyses. 3.3 Liquid BCD Detoxification System Sampling Organics collected from the process condensate separation and aqueous phase treatment system (PCSAPT) will be transferred and stored in the organic pre-treatment storage tank. Organics collected will be sampled once every two days and screened for PCB concentration using a PCB immunoassay test. Organics containing PCB concentrations above disposal facility acceptance criteria will require detoxification/dechlorination treatment in the LBCD process. Organics requiring treatment will be pumped into the LBCD reactor containing a heated mixture of carrier oil, sodium hydroxide and a catalyst. The sampling frequency may be modified to correspond with the quantity of organics being treated per LBCD batch and the variance of PCB concentrations contained in the collected organic stream. At a predetermined time, when the reaction period is anticipated to be completed (note: batch specific, dependant upon initial PCB concentration and other variables) samples will be collected from set sample ports. The sample will be screened for PCBs using the immunoassay test. When the reaction has been verified to be complete (i.e. PCB concentration below the disposal facility 's acceptance criteria) the reaction process will continue for an additional 1 to 2 hours as a precautionary measure. At the conclusion of the process, the treated organics will be cooled and then pumped to the organics transfer tank for physical separation of liquids. The organics transfer tank will be equipped with sample ports vertically aligned along the tank to collect samples at various levels throughout the tank. A corresponding manifold system will also be provided on the tank to allow decanting of the tank from various levels. Separated aqueous (water) phase, if any, will be removed from the tank and pumped upstream to the PCSAPT system. When sufficient quantity of organics are collected in the treated organic tank, a confirmation sample will be collected and analyzed for PCBs, and any other parameters required by the disposal facility. A certified laboratory will analyze the confirmation sample. ETG Environmental, Inc / BF A Environmental Consultants 14 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill . 3.4 Process Condensate Separation and Aqueous Phase Treatment Sampling The PCSAPT system is designed to separate process condensate into filter cake, aqueous phase, and organic phase and treat the aqueous phase. The following samples will be collected, at a minimum, to monitor the PCSAPT performance. 3.4.1 Condensate Collection Tank In an effort to evaluate the quality of the filter press feed, samples will be collected from the condensate collection tank. Data from these samples will allow the treatment operator to evaluate the scrubbers performance and contaminant loading into the PCSAPT. Samples will be collected from sample ports installed in line. The samples will be analyzed for TSS , pH, total organic carbon (TOC) and chlorides. The results are for informational purposes only. During the first PD and two weeks of full-scale operations a sample will be collected daily from each unit. Thereafter, the minimum sample schedule will be weekly. 3.4.2 Filter Cake Sampling The condensate and particulates from the condensate collection tank will be pumped into a filter press. The filter press will further separate the condensate into filter cake and filtrate. A composite sample of each day's production of filter cake during the PD and first two weeks of full scale operation will be screened for PCBs using the immunoassay test and tested on site for percent moisture. These samples are for informational purposes, as the filter cake may be reprocessed through the BBCD process, due to the anticipated elevated level of PCBs in the filter cake. The daily composite sample will be prepared by taking, two grab samples from each filter cake discharge in a 24-hour period and compositing the grab samples. It is anticipated that after two weeks of full-scale production, the sampling frequency can be reduced to once a week. 3.4.3 Sand Filter Influent Sampling Prior to the sand filter treatment, the process condensate has been treated through a series of unit operations. At this stage of the treatment process, the majority of solids, and heavy and light organics will have been removed from the condensate. To evaluate the performance of the process condensate separation system, a sample of the aqueous filtrate will be collected prior to proceeding through the aqueous phase portion of the treatment system (sand filtration and carbon polishing). The sample will be collected from a sample port located in line of the system. During the PD and first two weeks of full-scale operations a sample will be collected daily. ETG Environmental, Inc / BF A Environmental Consultants 15 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill · After which a sample will be collected, at a minimum, once per week. The sample will be analyzed on site for total suspended solids (TSS) and for PCBs. The sample is for informational purposes for the treatment operator to: 1) Evaluate the loading of PCBs and TSS on the aqueous phase treatment system, and 2) Monitor performance of the condensate separation system. The TSS loading will provide information to the treatment operator to anticipate and track backwashing cycles for the sand filters. The PCB concentration will enable the treatment operator to monitor effectiveness of PCB removal. Depending upon sampling results, more frequent sampling may be required. The filtrate stream will also be monitored for flow rate and total flow. 3.4.4 Midfluent Carbon System Sampling The aqueous phase treatment system concludes with, a minimum of two carbon units placed in series for polishing. A sample will be collected after the first carbon unit and analyzed on site for PCBs using the immunoassay test. The sample will be collected from a sample port located in line of the system. This data will determine when break through for PCBs has occurred, and carbon change-out is required. The data will also provide information to the treatment operator regarding carbon efficiency and anticipated carbon change-outs. A sample result above 200 ppb will require the carbon to be changed-out. Sample frequency will be, at a minimum, one sample per week, data results may dictate more frequent sampling. 3.4.5 Effluent Carbon Treatment Sampling The PCSAPT system concludes with the second carbon-polishing unit. Effluent from the PCSAPT will be used to rehydrate the treated materials. To monitor the effectiveness of the PCSAPT system for treatment of PCBs, an effluent sample will be collected at least weekly. The sample will be obtained from a sampling port installed in the system between the final carbon unit and the treated process water storage tank. The sample will be sent to laboratory and analyzed for PCBs. The target cleanup level is less than <200 ppb. 3.5 CBCD Quencher/Scrubber Recycle In an effort to evaluate the quality of the CBCD quencher/scrubber recycle, samples will be collected from the CBCD quencher/scrubber system. Data from these samples will allow the treatment operator to evaluate the CBCD quencher/scrubber performance. Samples will be collected from either a sample port installed in the recycle line, or directly from the recycling tank. ETG Environmental, Inc / BF A Environmental Consultants 16 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill The samples will be analyzed for TSS, pH, total organic carbon (TOC) and chlorides. The results are for informational purposes only. During the first PD and two weeks of full-scale operations a sample will be collected daily from each unit. Thereafter, the minimum sample schedule will be weekly. 3.6 Storm Water/Decontamination Water Sampling Water that may have come in contact with PCB-contaminated materials will be collected and treated in a separate system (not the PCSAPT). This water includes, but is not limited to, storm water run off from the process pad, decontamination water and water generated from dewatering the landfill. These water sources will be collected in a lined pond constructed at the north-end of the process pad. The water will be pumped through a sand filter followed by carbon polishing (minimum two carbon units in series). The treated water will be ( 1) discharged into the existing pond, currently used for discharge of treated water from the landfill, or (2) directly reused in the BCD process system. The treated water from the existing pond can then be used for dust control or process water make-up if desired. Sampling ports will be installed on the Storm Water/Decontamination Water treatment system in order to collect samples prior to treatment, midfluent of the carbon system and effluent quality. The influent and midfluent samples are for informational purposes, the effluent sample is a control sample and subject to applicable permits requirements. Currently, the Spray Irrigation System permit requires that the concentration of PCBs in the effluent wastewater to be applied by the system shall not exceed 1 ppb PCBs. The sampling frequency is once per month. The proposed sampling frequency for this project is once per week for the first four weeks of full-scale operation, followed by monthly, thereafter. The samples will be analyzed for PCBs. At a minimum, a laboratory certified to perform PCB analysis must analyze the effluent sample (control sample). All chain of custody's and sampling protocols must be followed. The actual permit received by the Contractor for the spray irrigation system will predicate the sampling frequency and analytical requirements. 3. 7 Miscellaneous Sampling The intent of the project is to treat all PCB-contaminated materials on-site. However, due to logistics, there will be a relatively small quantity of residual materials that will require disposal off-site. These may include, but not be limited to: • Spent Personal Protective Equipment (PPE), • Porous oversize debris, • Sand and carbon from last units used for treatment, • Decontamination water generated after treatment systems are dismantled, • Spent rags and materials used for decontaminating equipment, and • Miscellaneous trash and debris including scrap steel. ETG Environmental, Inc / BF A Environmental Consultants 17 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill These waste streams will require sampling and analytical data for proper disposal and documentation. The disposal facility requirements, the physical nature of the waste stream (porous, non-porous, solid, liquid, etc.), and how the waste was generated will determine the sampling and analytical requirements. The Contractor must make provisions within their Bid to account for the sampling, analytical and disposal costs for their residual waste streams being disposed off-site. ETG Environmental, Inc / BF A Environmental Consultants 18 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill 4.0 SAMPLING PROCEDURES AND PROTOCOLS This section describes the procedures to be followed for the collection of samples, decontamination of sampling equipment, and sampling preservation and handling methodologies. 4.1 Equipment Decontamination The decontamination procedures for aqueous and non-aqueous sampling equipment are described below: 4.1.1 Equipment Decontamination Aqueous Sampling All field sampling equipment will be laboratory cleaned, wrapped, and dedicated to a particular sampling point or location during a sampling episode. In instances where this will not be feasible, permission for field cleaning must be obtained from the NCDENR prior to the collection of any samples and be referenced in the approved site specific field sampling quality assurance project plan. The field sampling equipment cleaning and decontamination procedures will be as follows: 1. Laboratory grade glassware detergent plus tap water wash 2. Generous tap water rinse 3. Distilled and deionized (American Society for Testing and Materials (ASTM) Type II) water rinse 4. 10% nitric acid rinse* (trace metal or higher grade HN03 diluted with Distilled and deionized (ASTM Type II) Water) 5. Distilled and deionized (ASTM Type II) water rinse* 6. Acetone (pesticide grade) rinse** 7. Total air dry or pure nitrogen blow out*** 8. Distilled and deionized (ASTM Type II) water rinse*** Only if sample is to be analyzed for metals. * ** *** Only if sample is to be analyzed for non-volatile organics. Only if sample is to be analyzed for organics. Wherever possible, sampling devices will be numbered in a manner that will not affect their integrity and wrapped in a material ( e.g., aluminum foil) that has been cleaned and oven baked at 105°C or cleaned in the same manner as the equipment. Equipment will be custody sealed and information concerning decontamination methodology, date, time, and personnel should be recorded in the field logbook. The use of distilled and deionized water commonly available from commercial vendors may be acceptable for sampling equipment decontamination. NCDENR ETG Environmental, Inc / BF A Environmental Consultants 19 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill may require specific lot numbers from containers or analytical verification that the distilled and deionized water meets ASTM Type II specifications. Hexane is not a necessary solvent for dioxin, PCB, or other chlorinated organic sampling. The cleaning procedure outlined above is adequate for all sampling episodes. In those instances where acetone is a parameter of concern another solvent may be used. All substitutes must be approved by NCDENR. Decontamination will be carried out over a container and the material properly disposed off-site, or treated on site. Decontamination wastes must be disposed of properly. 4.1.2 Equipment Decontamination Non-Aqueous Sampling While it is preferred that all non-aqueous field sampling equipment be laboratory cleaned, wrapped, and dedicated to a particular sampling point or location during a sampling episode, field cleaning may be more practical. The field sampling equipment cleaning and decontan1ination procedures will be as follows: 1. Laboratory grade glassware detergent and tap water scrub to remove visual contamination. 2. Generous tap water rinse. 3. Distilled and deionized (ASTM Type II) water rinse. NOTE: If visual contamination persists, or gross contamination is suspected, the full eight step decontamination procedure found in Section 4.1.1 above will be performed. Wherever possible, sampling devices will be numbered in a manner that will not affect their integrity and wrapped in a material ( e.g., aluminum foil) that has been cleaned and oven baked at 105° C or cleaned in the same manner as the equipment. Equipment will be custody sealed and information concerning decontamination methodology, date, time, and personnel will be recorded in the field logbook. The use of distilled and deionized water commonly available from commercial vendors may be acceptable for sampling equipment decontamination. NCDENR may require specific lot numbers from containers or analytical verification that the distilled and deionized water meets ASTM Type II specifications. Decontamination will be carried out over a container and the residual liquid material must be properly disposed, or treated on site. ETG Environmental, Inc / BF A Environmental Consultants 20 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill When analysis for metals is required it may be necessary to use carbon steel split spoon sampling devices instead of stainless steel. If this is the case and it is necessary to utilize the acid rinse for removal of visible contamination, the nitric acid rinse may be lowered to a concentration of 1 % instead of 10% so as to reduce the possibility of leaching metals from the spoon itself. 4.2 Analytical Methodology Reference Table The following Table 4-2 Analysis of Target Compound List/Target Analyte List is designed to present field sampling personnel with information "at a glance" on sampling containers and field preservation requirements. The following Table is organized by analytical methodology, including the USEPA-Contract Laboratory Program, USEPA SW-846, and 40 CFR Parts 141 and 143 (National Primary and Secondary Drinking Water Regulations). The analytical methodologies in 40 CFR Part 136.3 include the 600 series methods and 40 CFR Part 141 includes the 500 series methods. These test procedures are incorporated as they exist on the day of approval and a notice of any change in these test procedures will be published in the Federal Register. In addition to providing field personnel with necessary sampling information, laboratory personnel will find these charts helpful in choosing a particular analytical methodology for a specific matrix. Quality Assurance/Quality Control (QA/QC) Personnel and those individuals involved with data validation will find the section on holding times particularly useful in ensuring the quality of analytical data. Finally there are descriptions for sample container preparation requirements which, when performed accurately, help ensure that analytical data generated from sample results is representative and is not subject to contamination from sample containers. A List of Acronyms is provided which included an explanation of abbreviations contained within Table 4-2. 4.3 Sampling Equipment Collection of environmental and waste samples often requires various types of sampling equipment to compliment specific situations encountered in the field. Selection of approved sampling equipment is based on the sample type, matrix, and physical location of the sample point and other site specific conditions. Consideration must also be given to the compatibility of the material being sampled with the composition of the sampler. This section addresses sampling equipment for the general types of samples encountered: environmental samples such as soil, sediment, wastewater samples; and residual and waste samples which are comprised of process wastes or other man-made waste materials.

PTFE is always the preferred material but may not always be practical. Therefore, there are specific conditions under which material other than PTFE may be used. Some of these include the use of stainless steel equipment for soil and sediment sampling, and the use of carbon steel split spoons for soil samples at depth. In some cases such as wastewater sampling, collection directly into the laboratory provided sample container eliminates the need for sampling equipment, as well as field blank quality assurance samples. While the preferred material of construction for sampling equipment used in waste sampling is PTFE or stainless steel, collection of some waste samples may not be possible with standard equipment. Therefore, alternate equipment constructed of different material may be necessary. In all cases, the material of construction will be compatible with the sample being collected and will not interfere with the parameters of concern. 4.3.1 Non-Aqueous Sampling Equipment Soils/Sediments There are many factors involved when choosing the proper sampling equipment for non-aqueous samples. The most important aspect of sampling is to get a representative sample of all horizons present. An attempt must also be made to maintain sample integrity by preserving its physical form and therefore, its chemical composition. The use of proper sampling equipment can accomplish these goals. Soil/Sediment samples will be collected to determine contamination in soils or extent of contamination. For the Warren County PCB Landfill Detoxification project surface sampling and waste pile sampling are two types of non-aqueous samples to be collected. Surface Samples The trowel or scoop will be used in collecting surface soil samples. They can also be used for a variety of other solid waste samples. The preferred sample equipment for the surface soils on this project is a trowel, which looks like a small shovel or a laboratory scoop. A laboratory scoop is similar to the trowel, but the blade is usually more curved and has a closed upper end to permit the containment of material. Scoops come in different sizes and makes. Many are coated with chrome paint which can peel off and get into the sample: these are unacceptable. Stainless steel scoops are preferred; however, scoops made from alternative materials may be applicable in certain instances. The decision for equipment construction of material other than stainless steel will be made at the discretion of NCDENR. ETG Environmental, Inc / BF A Environmental Consultants 28 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill · Waste Pile Sampler For collecting samples from the various material piles (treated and untreated) a waste pile sampler is recommended. It can also be used for sampling granular or powdered wastes or materials in large bins, barges, or soils. The waste pile sampler is essentially a large sampling trier. It is commercially available but it can be easily fabricated from sheet metal or plastic pipe. A polyvinyl chloride plumbing pipe 1.52 m (5 ft.) long by 3.2 cm (1 ¼ in.) in diameter by 0.32 cm (1/8 in.) wall thickness is adequate. The pipe is sawed lengthwise (about 60/40 split) until the last 10 cm ( 4 in.). The narrower piece is sawed-off and hence forms a slot in the pipe. The edges of the slot and the tip of the pipe are sharpened to permit the sampler to slide into the waste material being sampled. The unsplit length of the pipe serves as the handle. The plastic pipe can be purchased from hardware stores. Procedures for Use 1. Insert the sampler into the waste material being sampled at 0° to 45° from horizontal. 11. Rotate the sampler two or three times in order to cut a core of the material. 111. Slowly withdraw the sampler, making sure that the slot is facing upward. 1v. Transfer the sample into a laboratory cleaned sample container with the aid of a spatula and/or brush. v. Follow procedures and preservation and transport. 4.3.2 Aqueous Sampling Equipment Wastewater sampling equipment is typically designed to collect aqueous sample from the influent and effluent to a treatment facility. Since large volumes of water are being monitored over time, their ability to composite samples makes them most suitable. Samples may be collected manually or with automatic samplers. Whichever technique is adopted, the success of the sampling program is directly related to the care exercised during sample collection. Optimum performance will be obtained by using trained personnel. a) Manual Sampling There is minimal initial cost involved in manual sampling. The human element is the key to the success or failure of any manual sampling program. It is well suited to the collection of a small number of samples, but is costly and time consuming for routine and large sampling programs. ETG Environmental, Inc / BF A Environmental Consultants 29 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill . b) Automatic Sampling The project has been designed to include sample parts to obtain grab samples from various locations throughout the process Condensate Separation Aqueous Phase Treatment System and Storm Water/Decontamination Water Treatment System. However, automatic samplers can be beneficial because of their cost effectiveness, versatility, reliability, increased capabilities, greater sampling frequency and application to monitoring requirements specific to discharge permits. Automatic samplers are available with widely varying levels of sophistication, performance, mechanical reliability and cost. However, no single automatic sampling device is ideally suited for all situations. For each application, the following variables should be considered in selecting an automatic sampler: 1. Variation of water or wastewater characteristics with time. 2. Variation of flow rate with time. 3. Specific gravity of liquid and concentrations of suspended solids. 4. Presence of floating materials. Selection of a unit should also be preceded by careful evaluation of the range of intended use , the skill level required for installation and the level of accuracy desired. There are usually five interrelated subsystems in the design of an automatic sampler to consider. These are the sample intake, gathering, transport, storage, and power subsystems. 4.4 Sample Collection This section discusses the types of samples anticipated to be collected during the Warren County PCB Landfill Detoxification project. 4.4.1 Grab Sample A grab sample is a discrete aliquot that is representative of one specific sample site at a specific point in time. Since the entire sample is collected at one particular point and all at one time, a grab sample is representative only of those static conditions. If the source or condition is fairly consistent over a period of time and/or geographical area, the grab sample can be considered to be fairly representative. However, for sources that vary greatly over time, distance or area (e.g., release of contaminants into moving water or air) the representativeness of a grab sample is not as great. 4.4.2 Composite Sample A composite sample is a non-discrete sample composed of more than one specific aliquot collected at various sampling points and/or at different points. Composite samples may give an "average" concentration or composition of contaminant in ETG Environmental, Inc / BF A Environmental Consultants 30 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill individual grab samples is diluted proportionately to the number of samples taken. It is advisable that if a positive identification is made in the course of analyzing a composite sample, that the discrete samples then be analyzed individually to determine the true distribution of contaminant throughout each component of the composite. When collecting samples at hazardous waste sites, primarily grab sampling is employed. However, compositing samples have merit when performed for specific purposes and under known conditions, such as this project, where composite samples represent "average" concentrations over specific areas and/or processing days. 4.4.3 Surficial Sampling Surficial sampling is used to assess the existence and/or extent of contamination on various surfaces rather than in a soil, water or air matrix. For example, the interior of a building may be assessed by collecting wipe samples of the process vessels and interiors of ventilation ducts . The three types of samples (wipe, chip and sweep) are for similar purposes, the three types of sampling are performed in very different ways because they are intended to assess different surface areas. A) Wipe Samples This method of monitoring surficial contamination is intended for non- volatile species of analytes ( e.g., PCB, TCDD, TCDF) on non-porous surfaces (e.g., metal, glass). Sample points should be carefully chosen and should be based on site history, manufacturing processes, personnel practices, obvious contamination, migration pathways and available surface area. Suggested sampling points include process vessels, ventilation ducts and fans, exposed beams, window panes, etc. The area wiped should be large enough to provide a sufficient amount of sample for analysis (smaller sample volumes cause higher detection limits). To collect a wipe sample the following equipment is needed: A ruler or measuring tape to measure out the area being wiped Disposable surgical gloves, to be changed prior to handling clean gauze, sample container or solvent Sterile, wrapped gauze pad (3 in. x 3 in.) Appropriate pesticide grade solvent or distilled and deionized water To facilitate the collection of a wipe sample, 3 in. x 3 in. gauze should be utilized. The use of filter paper for wipe sampling is not recommended. Filter paper will tend to rip and crumble if the surface wiped is slightly ETG Environmental, Inc / BF A Environmental Consultants 31 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill rough. If filter paper is to be used, it should be four inch diameter heavy gauge paper, such as Whatman #4 Filter Paper. The solvent of choice may change based upon the analytes of interest and surface being sampled. Gauze pads for semi-volatiles, pesticide and PCB samples should be moistened in a 1 :4 acetone/hexane mixture, and those for metals with distilled and deionized water. The gauze pad should be soaked and excess squeezed out immediately before the collection of each sample. Use of pre-soaked pads is not acceptable. Alternate solvents may be acceptable for certain parameters, however, their approval for use will be at the discretion of NCDENR. Occasionally samples are desired from painted or waxed surfaces. Since hexane may degrade the finish or pick up interfering substances, an alternative solvent should be used. In this case, methanol or distilled/deionized water for semi-volatiles, pesticides and PCBs and distilled and deionized water alone for metals should be used. Surface interference's should be recorded in the field logbook. Once the sample location has been determined, sample collection can begin. It is recommended that an area be premeasured ( e.g. 25 cm x 25 cm) to allow for easier calculation of final results. However, this is not always feasible and may be done after area is wiped. Wearing a new pair of disposable surgical gloves, remove the gauze pad from its sterile wrapping and soak it with the appropriate solvent. Wipe entire area to be sampled once in the horizontal direction and once in the vertical direction, applying moderate pressure. Wipe the entire area so that all the sample material is picked up. Place the gauze pad into the sample container. A blank must always be collected for each wipe sampling episode in order to ensure the quality of the data. This blank will help to identify potential introduction of contaminants from the pad, solvent, sample container or ambient air conditions. To perform a wipe blank, start by wearing new gloves, then wet a gauze pad with the solvent or water (for each collection parameter) and place the pad directly into the sample bottle. When samples are submitted for analysis, the laboratory should be told to rinse the sample jars with the appropriate extraction or digestion solvent, depending on the analysis to be performed, when transferring sample to the extraction glassware. This will ensure that the entire sample has been removed from the container. B. Chip Samples This method of monitoring surficial contamination is intended for non- volatile species of analytes (e.g., PCB, TCDD, TCDF) on porous surfaces ETG Environmental, Inc / BF A Environmental Consultants 32 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill • (e.g., cement, brick, wood). Sample points should be carefully chosen and should be based on site history, manufacturing processes, personnel practices, obvious contamination and available surface area. Suggested sampling points include floors near process vessels and storage tanks, loading/unloading areas, etc. The sampling area should be large enough to provide a sufficient amount of sample for analysis (smaller sample volumes cause higher detection limits). To facilitate the calculations once the analytical data is received, the area sampled should be measured. To collect a chip sample, the following equipment is needed: A ruler, or measuring tape to measure out area to be sampled Disposable surgical gloves, to be changed prior to collection of each sample Decontaminated chisel of borosilicate construction and hammer or electric hammer Dedicated natural bristle brush and a dust pan lined with aluminum foil or one that is dedicated, decontaminated and constructed of a pre-approved material which will not interfere with the contaminants of concern Container for sample Once the sample location has been determined and marked off, sample collection can begin. Wearing a new pair of disposable gloves, and using a decontaminated chisel and hammer, break up the surface to be sampled. An effort should be made to avoid scattering pieces out of the sampling area boundary. Any pieces that fall outside the sampling area should not be used. The area should be chipped to less than one-quarter inch (preferably 1/8 in.). Record how deep chips were taken. Collect the chipped pieces using a dedicated, decontaminated dust and natural bristle brush and transfer the sample directly into the bottle. C. Sweep Samples This method of monitoring surficial contamination is intended for non- volatile species of analytes ( e.g., PCB, TCDD, TCDF) in residue found in porous (e.g., asphalt) or non-porous (e.g., metal) surfaces. Sweep sampling allows collection of dust/residue samples that may help in the assessment of contaminant determination and delineation. Sample points should be carefully chosen and should be based on site history, manufacturing processes, personnel practices, obvious contamination, migration pathways and available surface area. Suggested sampling points include areas in ventilation systems where dust can collect, floor surfaces near process vessels and storage tanks ( e.g., linoleum floors where a solvent cannot be used or too much residue exists for a wipe sample to be easily collected), street gutters where ETG Environmental, Inc / BF A Environmental Consultants 33 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill contaminated sediments may have migrated and accumulated, etc. The area sampled should be large enough to provide a sufficient amount of sample for analysis. To collect a sweep sample the following equipment is needed: Dedicated natural bristle brush Decontaminated stainless steel spatula and/or a dust pan lined with aluminum foil , or one that is dedicated, decontaminated and constructed of a pre-approved material which will not interfere with the contaminants of concern Disposable dedicated surgical gloves to be changed prior to collection of each sample. Container for sample Once the sample location has been determined, sample collection can begin. Wearing a new pair of disposable gloves, sweep all residue in the area to be sampled onto a decontaminated or dedicated dust pan or directly into the sample container. A decontaminated or dedicated spatula may be used to aid in transferring the sample into the sample bottle. D. Rinsate Samples This method of sampling is utilized to determine if surfaces contain hazardous waste residual after being cleaned. It is normally associated with drum storage pads, floors of buildings and the inside of waste tanks. Rinsate samples are performed by collecting the water from the last rinse when cleaning a tank or surface area. This water, which is normally potable water, is then analyzed and compared against a blank consisting of the same type of water. 4.4.4 Post Sampling Activities There are several steps to be taken, even after the transfer of the sample into the sample bottle, that are necessary to properly complete collection activities. Once the sample is transferred into the appropriate container, the bottle will be capped and, if necessary, the outside of the bottle will be wiped with a clean paper towel to remove excess sampling material. The bottle is not to be submerged in water in an effort to clean it. Rather, if necessary, a clean paper towel moistened with distilled and deionized water is to be used. The sample will be preserved immediately (4°C or appropriate reagent), properly labeled, packaged for transportation and custody sealed. Information such as sample number, location, collection time and sample description will be recorded in the field logbook. Associated paperwork ( e.g., Chain of Custody forms, ETG Environmental, Inc / BF A Environmental Consultants 34 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill Sample Analysis Request forms) will then be completed and remain with the sample. The samples will be packaged in a manner that will allow the appropriate storage temperature to be maintained during shipment to the laboratory. Samples will be delivered to the laboratory so the proper temperature level is assured and analytical holding times are not exceeded. 4.5 Documentation Proper documentation of all site activities will be a crucial part of the field investigation process. Documentation must be maintained to trace the repossession and handling of samples from the time of collection through analysis and disposition. Documentation procedures include: sample labels, sample seals, field log books, chain of custody records, sample analysis request forms , and laboratory sample logs. The details of all sampling activities must be recorded in a field logbook. When samples are collected, documentation in the form of sample analysis request forms must be completed. Proper completion of these forms and the field log book are necessary to support potential enforcement actions that may occur from the results of sample analysis. 4.5.1 Field Log Books Field logbooks must be bound and will have numbered, water resistant pages. All pertinent information regarding the site and sampling procedures must be documented. Notations will be made in logbook fashion, noting the time and date of all entries. Information recorded in this notebook should include, but not be limited to, the following: Name of person keeping log; field instrument calibration information; location of sampling points (including justification) number of samples taken, volume of samples taken; preservation; method of sample collection and any factors that may affect its quality; date and time of sample collection and any factors that may affect its quality; name of collector; all sample identification numbers; description of samples; weather conditions on the day of sampling and up to forty-eight hours previous and any field observations. 4.5.2 Documenting Sampling Points Sampling points should be documented as to their exact location for purposes of future sampling. This is accomplished through the use of a monument, measuring tape and compass, or surveying instrumentation for samples collected in the field. A monument( s) will be installed to act as a stationary reference point from which all sampling points can be measured using a compass and measuring tape, or surveying instrument. When establishing a sampling point, follow this procedure: ETG Environmental, Inc / BF A Environmental Consultants 35 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill . Standing at the monument, facing sampling point, use the compass hairlines to determine degree of direction. Line of sight should run from the monument, through both hairline needles on the compass, to the sampling point. When first establishing the sampling point, record the degree and direction reading from the compass in the field notebook, along with the distance measurement, from the monument to the exact sampling point. In the future, field investigating teams should have no difficulty finding the exact locations from which previous samples were taken when they are provided with the monument and compass data. 4.5.3 Photo-Documentation All sampling points should be documented on film. A film record of a sampling event allows positive identification of the sampling point. Photographs are the most accurate and convenient demonstration of the field personnel's observations. Photographs taken to document sampling points should include two or more reference P,oints to facilitate relocating the point at a later date. Keeping a record of photographs taken is crucial to their validity as a representation of an existing situation. Therefore, for each photograph taken several items should be noted in the field notebook: 1. Date 2. Time 3. Photographed by (signature) 4. Name of site 5. General direction faced and description of the subject taken 6. Sequential number of the photograph and the roll number Photo-documentation is invaluable if the sampling and subsequential analytical data ends in litigation, enforcement, or cost recovery actions. Video coverage of a sampling episode can be equally or even more valuable than photographs because it can be used to prove that samples were taken properly as well as where they were taken. It can be used as a record of site conditions and can give those who have not been on-site an idea of the circumstances. 4.5.4 Sample Collection Paperwork A) Sample Labels Sample labels are an important part of proper documentation as their use not only reduces the possibility of confusing sample containers, but also provides the information necessary during handling to complete chain-of-custody forms. ETG Environmental, Inc / BF A Environmental Consultants 36 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill. Sample containers should be pre-labeled before sample collection and the labels themselves protected from the sample matrix with a clear tape covering. Sample labels should include the sample number; parameter sampled; date; time sampled; sampler's initials; preservative; and site name or location. B) Chain of Custody/Sample Analysis Request When samples are collected for laboratory analysis, additional documentation procedures are required. The Chain of Custody (COC) form is intended as a legal record of possession of the sample. The COC should be initiated at the laboratory at sample container receipt, remains with the sample at all times and bears the name of the person assuming responsibility for the samples. This person is tasked with ensuring secure and appropriate handling of the bottles and samples. When the form is completed, it should indicate that there were no lapses in sample accountability. In order to assure that the proper analysis is performed on the samples, the laboratory performing the analysis may require additional information and/or the regulatory agency involved. Such as identification of samples by number, location and the time collected and desired analysis. This information should act as a confirmation to laboratory contacts made prior to the sample event initiation. ETG Environmental, Inc / BF A Environmental Consultants 37 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill 5.0 QUALITY ASSURANCE AND QUALITY CONTROL Quality assurance measures are associated with each sampling and analysis event as an additional measure of control to assure that the sample delivered to the laboratory for analysis is representative of site conditions. The sampling plan outlines how the representative quality of the samples will be assured. This includes but is not limited: laboratory Standard Operating Procedure (SOP), field SOP, sample bottle preparation, equipment decontamination, trip blanks, field blanks, duplicates, split samples, performance evaluation samples, sample preservation and handling, chain of custody, analysis request, analytical methods, parameters and deliverables. 5.1 Laboratory Procurement The Contractor will provide as part of this Plan the QA/QC package of each laboratory procured for the project. The laboratory must provide a statement (on all Analytical Reports) certifying that the laboratory is either certified for applicable parameters under 15 North Carolina Administrative Code (NCAC) Subchapter 2H.0800, or that it is a contract laboratory under EPA's CLP. When selecting a laboratory, the following factors are to be considered: Whether the laboratory has maintained the required certifications and approvals for specific parameters for which samples are to be analyzed. Whether the laboratory is available to perform the analysis requested. Whether the laboratory has the capacity to handle all the samples that will be delivered. Whether the laboratory can perform the analysis within the time frame specified (if applicable). Whether the laboratory has sufficient backup instrumentation procedures. The laboratory's proximity to the site or capability to pick up and deliver as needed. 5.2 Sample Containers Prior to the collection of a sample, consideration must be given to the type of container that will be used to store and transport the sample. The party requesting the analysis is responsible for requesting the proper sample containers. Their selection is based on the sample matrix, potential contaminants to be encountered, analytical methods requested, and the laboratory's internal quality assurance requirements. Selection of appropriate sample containers should also be based upon review of the criteria listed below, and the information contained in Table 4-2. ETG Environmental, Inc / BF A Environmental Consultants 38 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill 5.2.1 Reactivity of Container Material with Sample Choosing the proper composition of sample containers ensures that the chemical and physical integrity of the sample is maintained. For sampling potentially hazardous material, glass is the recommended container type because it is chemically inert to most substances. Plastic containers are not recommended for most hazardous wastes because the potential exists for contaminants to adsorb to the surface of the plastic or for the plasticizers to leach into the sample. In some instances, the sample characteristics or analytes of interest may dictate that plastic containers be used instead of glass. Because some metals species will adhere to the sides of glass containers in an aqueous matrix, plastic bottles must be used for samples collected for metals analysis. In the case of a strong alkali waste or hydrofluoric solution, plastic containers may be more suitable because glass containers may be etched by these compounds creating adsorptive sites on the container surface. 5.2.2 Volume of the Container The analytical method and the sample matrix will dictate the volume of sample to be collected. The laboratory must supply bottles of sufficient volume to perform the required analysis. In most cases, the methodology dictates the volume of the sample material required to complete the analysis. However, individual laboratories may provide larger volume containers for various analytes to ensure sufficient quantities for replicates or other quality control checks. 5.2.3 Color of Container Whenever possible, amber glass containers should be used to prevent photodegradation of the sample, except when samples are being collected for metals analysis. If amber containers are not available, containers holding samples should be protected from light. However, 40ml clear glass vials are often provided by laboratories for Volatile Organic Analysis (VOA)/aqueous analysis and are acceptable for use. 5.2.4 Container Closures Container closures should form a leak-proof seal (i.e., screw caps or ground glass stoppers). Closures must be constructed of a material, which is inert with respect to the sampled material, such as PTFE (e.g., Teflon®). Alternately, the closure may be separated from the sample by a closure liner that is inert to the sample material such as PTFE liner or septum. ETG Environmental, Inc / BF A Environmental Consultants 39 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill 5.2.5 Decontamination of Sample Containers and Chain of Custody Sample containers must be laboratory cleaned, preferably by the laboratory performing the analysis. The cleaning procedure is dictated by the specific analysis to be performed on the sample. The sample bottles prepared for shipment will be accompanied by a chain of custody and the cooler or shuttle containing them should be custody sealed. The chain of custody must also accompany the bottles during transportation to the field, sample collection, transportation back to the laboratory, during analysis and identify final disposal of the sample container. When collecting a sample, sampling personnel should record the seal number associated with each sample shuttle or cooler and record whether the seal was intact upon arrival in the field. This assures that the sample containers were not tampered within the time between their preparation and their arrival in the field. After sample collection, the bottles again will be sealed into the shuttle or cooler and the seal number will be recorded in the field logbook. Upon arrival at the lab, the person receiving the sample will note the number and condition of the custody seal. 5.2.6 Sample Bottle Storage and Transport No matter where the sample bottles are, whether at the laboratory waiting to be packed for shipment or in the field waiting to be filled with sample, care must be taken to avoid contamination. Sample shuttles, or coolers, and sample bottles themselves must be stored and transported in clean environments. Sample bottles and clean sampling equipment must never be stored near solvents, gasoline, or other equipment that is a potential source of contamination. When under chain of custody, sample bottles must be secured in locked vehicles or storage areas, custody sealed in shuttles or in the presence of authorized personnel. 5.3 Procedures for Quality Assurance and Quality Control (QA/QC) QA/QC samples are intended to provide control over the collection of environmental measurements and subsequent validation, review, and interpretation of generated analytical data. QA/QC samples will be performed for "Control Samples" as identified in Table 3-1. The various types of blank samples and related QA/QC concerns such as packaging, handling, preparation and actual procurement of samples from field locations are discussed below. The trip blank is used exclusively for volatile organic analysis (aqueous sampling only) and its purpose is to measure possible cross contamination of samples during shipping to and from the site. The trip blank is never opened and travels to the site with the empty sample bottles and back from the site with the collected samples in an effort to simulate sample handling conditions. Contaminated trip blanks may also indicate inadequate bottle cleaning or blank water of questionable quality. ETG Environmental, Inc / BF A Environmental Consultants 40 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill · The primary purpose of this type of blank is to detect additional sources of contamination that might potentially influence contaminant values reported in actual samples both quantitatively as potential sources of contamination. Laboratory reagent water Sample containers Cross contamination in shipment, bottle handling and storage Ambient air or contact with analytical instrumentation during preparation and analysis at the laboratory Laboratory reagents used in analytical procedures The purpose of a field blank is to place a mechanism of control on sample equipment handling, preparation, storage, and shipment. The field blank travels and is stored with the samples bottles, and is also representative of bottle shipment effects on sample quality. By being opened in the field and transferred over a cleaned sampling device (where applicable), the field blank is indicative of ambient conditions and/or equipment conditions that may potentially affect the quality of the associated samples. The primary purpose of this type of blank is to provide an additional check on possible sources of contamination beyond that which is intended for trip blanks. A field blank serves a similar purpose as a trip blank regarding blank water quality and sample bottle preparation. However, it is primarily used to indicate potential contamination from ambient air as well as from sampling instruments used to collect and transfer samples from point of collection into sample containers (it may also be referred to as the field rinsate blank). The following is a breakdown by matrix of blank sample requirements. 5.3.1 Non-Aqueous Matrix a. Field Blanks 1. Description -The performance of field blanks requires two (2) sets of identical bottles; one set filled with demonstrated analyte free water provided by the laboratory performing the sample analysis, and one empty set of bottles. The bottles should also be identical to those provided for aqueous sample collection. Note: Since field blanks are aqueous, the laboratory must provide water for volatile analysis in 40 ml septum vials. Although for soil VOA sample collection in the laboratory may provide 4 oz. Wide mouth bottles. At the field location, in an area suspected to be contaminated, the water is passed from the full set of bottles through the dedicated or field decontaminated sampling device(s) and into the empty set of bottles. This will constitute identical bottle to bottle transfer. Field blanks must be preserved in the same manner as samples and ETG Environmental, Inc / BF A Environmental Consultants 41 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill 5.3.2 only need to be collected and analyzed for volatile organics when volatile organics constitute a parameter being investigated. 11. Frequency -For sampling events lasting more than one day, field blanks for the non-aqueous matrix should be performed at a rate of 10% of the total number of samples collected throughout the event. If, for example, 40 samples were to be collected over a six-day period, then only four field blanks would be required. For one-day sampling events, with the total number of samples collected being less than 10, it is required that one field blank be collected. One a site specific basis, QA frequency requirements may be amended at the discretion of NCDENR. However, it is not necessary to collect more than one field blank per day. b. Trip Blanks TRIP BLANKS ARE NOT REQUIRED FOR THE NON-AQUEOUS MA TRIX unless specifically requested for Special Analytical Services (SAS) by NCDENR. Aqueous Matrix a. b. Field Blanks l. Description -Same as a.1. above with one exception: Field blanks must be analyzed for all the same parameters as samples collected that day. 11. Field blanks will not be required when a sample is collected directly from a source into sampling container. 111. Frequency -Field blanks for the aqueous matrix must be performed at a rate of one per day. Trip Blanks 1. Description -Trip blanks are required for aqueous sampling events. They consist of a set of sample bottles filled at the laboratory with laboratory demonstrated analyte free water. These samples then accompany the bottles that are prepared at the laboratory into the field and back to the laboratory, along with the collected samples for analysis. These bottles are never opened in the field. Trip blanks must return to the lab with the same set of bottles they accompanied to the field. At a minimum trip blanks must be analyzed for volatile organic parameters. 11. Frequency -Trip blanks will be included at a rate of one per sample shipment. ETG Environmental, Inc / BF A Environmental Consultants 42 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill . 5.3.3 Air Matrix Trip and field blank procedures and frequencies for the various air sampling methods available should follow the specifications of the individual analytical method utilized. QA sample requirements may be amended at the discretion of NCDENR. 5.3.4 Blank Water Quality The demonstrated analyte free water used in the field and trip blanks must originate from one common source and physical location within the laboratory and must be the same as the method blank water used by the laboratory performing the specific analysis. The use of commercially prepared water or water not originating from the laboratory analyzing the samples is not permitted. An exception to this requirement is allowable if: 1. it is the same water used for method blank analysis, 2. the laboratory has analyzed that water and generated data from a specific batch/lot of containers, 3. The blank sample is drawn from an unopened container from the same batch/lot thus documenting the water is free of contaminants ( demonstrated analyte free). The laboratory performing the analysis may be required to provide documentation that trip and field blank water was demonstrated analyte free if contamination is detected in blanks, or at NCDENR's discretion. This would be verified by analytical results of method blanks run by the laboratory on the day of trip and field blank preparation and shipment. This does not, however, change requirements for the analysis of method blanks on the day of sample analysis at the laboratory. A method blank is blank water, which is carried through the entire sample preparation procedure and analysis at the laboratory. It is utilized as a check on laboratory procedures as well as possible contamination from laboratory equipment (i.e. reagents, glassware, etc.). The use of solid method blanks for volatiles and extractable organics is unacceptable to NCDENR. Method blanks associated with non-aqueous samples should consist of laboratory demonstrated analyte free water (documentation available upon request) which is prepared and analyzed in the same manner as the samples. 5.3.5 Sample Handling and Holding Times a. Handling Time Field trip and blank samples must travel with sample containers and must arrive on-site within one day of their preparation in the lab. Blanks and ETG Environmental, Inc / BF A Environmental Consultants 43 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill their associated sample may be held on-site for no longer than two calendar days, and must arrive back in the lab within one day of shipment from the field. This constitutes a maximum of a four (4) day handling time. Blanks and all samples must be maintained at 4°C while stored on- site and during shipment. Sample bottles and blanks must be handled in the same manner prior to their return to the laboratory. The only acceptable exception to handling time requirements is when sampling storm water runoff. The spontaneity of storm conditions precludes any possibility for preplanning sample bottle shipment. Therefore, due to these obvious logistical constraints, trip and fi eld blanks are not normally required. While the exception is understandable, the storage of these sample bottles must be carefully controlled to ensure the possibility of cross contamination is kept to an absolute minimum. b. Maximum Holding Time The clock governing holding times for samples and blanks analyzed by CLP methodologies begins when the sample is received in the laboratory as documented on the laboratory 's chain of custody form verified time of sample receipt (VTSR). Holding times for individual parameters are dictated by the specific analytical method being used. The holding time clock for samples and blanks analyzed by SW-846 or 40 CFR, Parts 136 ad 141 , begins at the time of sample collection. 5.4 Additional QA/QC Samples Additional parameter blanks will be required for specific "control" samples as identified in Table 3-1. 5.4.1 Duplicate Samples Obtained in the Field Collection of duplicate samples provides for the evaluation of the laboratory's performance by comparing analytical results of two samples from the same location. Duplicate samples can be included at the discretion of the Contractor or requested by NCDENR. 1. Aqueous Matrix Duplicates Duplicates of water samples (process water effluent) should be obtained by alternately filling sample containers from the same sampling device for each parameter. ETG Environmental, Inc / BF A Environmental Consultants 44 Final March 2000 Final Verification/Confinnation Sampling Plan Warren County PCB Landfill 11. Non-Aqueous Matrix Duplicates Obtaining duplicate samples in a soil or sediment matrix requires homogenization of the sample aliquot prior to filling sample containers. Regardless, volatile organic samples must always be taken from discrete locations or intervals without compositing or m1xmg. This practice is necessary to prevent loss of volatile constituents and to preserve, to the extent practicable, the physical integrity of the volatile fraction. Homogenization of the sample for remaining parameters is necessary to generate two equally representative samples. Note that enough sample must be collected at one time in order to fill all the necessary sample containers. It may be necessary to co-locate or depth integrate collection so enough sample volume is available. Moisture content, particle size, and adsorption properties of various soils, sediments and waste materials may inhibit the ability to achieve complete mixing prior to filling sample containers. Homogenization will be accomplished by filling a properly decontaminated stainless steel tray or bowl with the sample and mixing it with a decontaminated stainless steel or Teflon® instrument. The extent of mixing required will depend on the nature of the sample and should be done to achieve a consistent physical appearance prior to filling sample containers. Once mixing is completed the sample will be divided in half and containers will be filled by scooping sample material alternately from each half. 5.4.2 Splitting Samples with Responsible Parties It is possible that other interested parties may desire to obtain samples for analysis which are duplicates of those obtained by NCDENR personnel or the Contractor. If this becomes necessary, procedures for obtaining duplicate samples described above will be followed. In order to maintain the integrity of any sample "split" between interested parties, the following procedures will be followed: 1. Personnel authorized by NCDENR using approved NCDENR sampling methods shall be permitted to obtain all sample aliquots. 11. Other interested parties must provide their own sample containers, blank samples, preservatives, sample shuttles, chain of custody forms, etc. ETG Environmental, Inc / BF A Environmental Consultants 45 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill n1. Sampling procedures shall be witnessed by NCDENR personnel to verify consistent handling and packaging of each set of samples. 1v. Analytical data generated by interested parties which is submitted for purposes of challenging NCDENR results or for informational purposes only shall first be subject to standard NCDENR "Quality Assurance Data and Validation of Analytical Sample Deliverables" procedures prior to being evaluated and considered for inclusion in the site evaluation process. v. Duplicate samples, trip blanks and field blanks must be included as part of those samples which are split between the two or more parties involved. v1. All interested parties desiring to obtain split samples during planned sampling episodes must provide NCDENR with a minimum of two weeks notice. This is essential for planning purposes and to avoid confusion or delays in the field. 5.4.3 Performance Evaluation Samples (PE) In certain instances when a laboratory's quality assurance performance is in question, splitting samples may not prove as useful as providing blind performance evaluation samples to a laboratory since analytical performance and accuracy differs from laboratory to laboratory. One laboratory cannot be considered a "referee" whose performance can be considered the standard against which another's can be measured. Performance evaluation samples provide information on a laboratory's performance based upon analysis of that sample which contains parameters of a known and defined concentration. Therefore, at the discretion of NCDENR, PE samples may be required as a QA/QC check on laboratory performance for a particular sampling event or site investigation. Performance Evaluation samples can be employed in two ways. First, the PE sample can be used to pre-qualify a laboratory. Since the current NCAC Laboratory Certification procedures apply only to aqueous samples, a soil PE sample is useful in pre-qualifying a laboratory for soil or sediment evaluation projects. Second, a PE sample submitted blind with a sample lot to a contract laboratory is an available method for evaluating the quality of the analytical data. PE samples consist of pre-measured, pre-determined samples of known origin and concentration, which are submitted for analysis along with a sample shipment from the field. The PE samples will be provided by NCDENR and the Contractor is responsible for their delivery to the laboratory performing the analysis along with other samples submitted for analysis of a PE sample is then compared to known concentrations as a measure of laboratory performance. Deviations from known concentrations may indicate improper calibration or other laboratory error ETG Environmental, Inc / BF A Environmental Consultants 46 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill that may have influenced the results reported for those samples collected in the field. Dioxin PE samples are the most frequently utilized. Others include PCBs, BNAs, VOAs and Pesticides in soil; Metals in sediment; and EPA prepared PE samples in an aqueous matrix. The particular concentration and species as well as assigned code number remain confidential until data is reviewed and validated. 5.4.4 Matrix Spike/Matrix Spike Duplicate Analyses When performing CLP organic extractable analysis, the laboratory must be supplied with triple sample volume for each Sample Delivery Group (SDG) in order to perform matrix spike and matrix spike duplicate analyses. This does not include field or trip blanks. Blanks do not require separate matrix spike or duplicate analyses regardless of their matrix. As stated in the CLP Statement of Work (SOW), the limits on an SDG are: each case of field samples, or each 20 field sample within a Case, or each fourteen calendar day period during which field samples in a Case are received (said period beginning with the receipt of the first sample in the SDG), whichever comes first. 5.4.5 Background/(Baseline) Samples Background samples are used for comparison of site conditions to the surrounding environment. They should be collected and handled in the same manner as all other samples. Baseline air samples will be collected prior to site construction activities. When dioxin or dioxin/furan sampling is performed, quality control samples may be required to accompany environmental samples regardless of the laboratory's status in the Contract Laboratory Program. 5.5 Sample Presenration Requirements Certain analytical methodologies for specific analytes require chemical additives in order to stabilize and maintain sample integrity. Generally this is accomplished under two scenanos: Preservative may be added to the sample bottles by the laboratory prior to shipment into the field or, Preservatives are added in the field immediately after the samples are collected. ETG Environmental, Inc / BF A Environmental Consultants 47 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill Many laboratories provide pre-preserved bottles as a matter of convenience and to help ensure that samples will be preserved immediately upon collection. A problem associated with this method arises if not enough sample is collected, resulting in too much preservative in the sample. More commonly encountered problems with this method include the possibility of insufficient preservative provided to achieve the desired pH level or the need for additional preservation due to chemical reactions caused by the addition of sample liquids to pre-preserved bottles. NCDENR approves the use of pre- preserved bottles. However, field sampling teams must always check the pH level and be prepared to add additional preservatives to samples if necessary. When samples are preserved after collection, special care must be taken. The transportation and handling of concentrated acids into the field requires additional preparation and adherence to appropriate preservation procedures. All preservation acids used in the field should be trace metal grade or higher. The following guidelines are recommended to achieve safe and accurate preservation of samples in the field. I. Sampling teams must be properly equipped to conduct preservation of samples in the field. To accomplish this task the following items are necessary: Graduated pipets Pipet bulbs Preservatives in glass containers with their content and concentration clearly labeled pH paper Carrying case clearly labeled and constructed of appropriate material to facilitate safe transportation of preservatives in vehicles and in the field. 2. Sampling teams must also be properly equipped with appropriate health and safety equipment. Use of and immediate access to the following items are strongly recommended. Protective goggles Disposal gloves Lab apron First aid kit Portable eye wash station Containerized tape water for immediate flushing if spillage occurs onto clothing 3. A level surface area should be designated to conduct preservation activities. A clean sheet of plastic sheeting should be placed over the area and secured. ETG Environmental, Inc / BF A Environmental Consultants 48 Final March 2000 Final Verification/Confirmation Sampling Plan Warren County PCB Landfill 4. Personnel assigned to conduct preservation activities must be familiar with specified preservation requirements and verify that the necessary pH level has been achieved. To accomplish this task, a small amount of the preserved sample aliquot should be placed into a separate clean beaker or the container lid. The liquid should then be checked with the pH paper so as to indicate that the desired pH level has been achieved. Under no circumstances should the test sample aliquot be returned into the container retaining the sample for analysis. Volatile organics being analyzed for 602, 603 , 624 and 1624 ( drinking water and wastewater analysis) must be preserved with HCI. Preservation requirements for other individual parameters are referenced in the charts found in Table 4-2. These charts also indicate any additional preservation required upon arrival of samples at the laboratory as cited in the specific methodologies. The source of preservatives is also of concern. They may be provided in bulk by the laboratory performing the analysis or purchased from a commercial laboratory supply vendor. All preservative containers must be labeled with respect to contents, concentration, laboratory grade and the date of purchase or preparation. Again, under no circumstances should the test sample aliquot be returned into the container retaining the sample for analysis. 5. Preservation must take place immediately upon sample collection except when samples are to be filtered. Samples requiring filtration must be processed immediately after collection. Filtered samples will then be preserved immediately following the filtration process. 6. Samples must be placed into a cooler and maintained at 4°C immediately upon collection and preservation.
