EPA's Superfur.d Innovative Technology Evaluation (SITE) Program A technology dcmon5tration to be pe:formed at the Koppers . Company Superfund site, located in Morrisville, North Carolina A Vi,;itors' Day to be held on August 31, 1993 at the Koppers Company site INTRODUCTION _The U.S. Er.viconmental Protection Agency (EPA) identifies new · methods for hazardous wa,1c cleanup through its SITE Program. Under this progr=, created in 1986, innovative treatment tech- nDlogies that IT'.ay sigr.ificantly reduce the toxicity, mobility, or · volwne ofhaz.ardous waste are demonstrated and evaluated. 1he SITE Program also generates reliable performance and cost information on the technologies for use in evaluating cleanup alternatives for similarly contaminated sites. The technology proposed for demonstration is the Base-Catalyzed Decomposition (BCD) technology developed by EPA's Risk Reduction Engineering Laboratory in Cincinnati, Ohio, using the SAREX® TIITRM-O-DETOX™ system developed by ETG Environmental, Inc. (ETG), and Separation and Recovery Sys- tems, Inc. (SRS). The purpose of this demonstration is to assess how well the technology removes pentachlorophenol (PCP) and dioxins from the soil at the Koppers Company Superfund site in Morrisville, North Carolina. EPA'S SITE PROGRAM Each year, EPA solicits proposals from priva((; tc.:hnology devel- opers to demonstrate innovative technologies under the SITE Prc>gran1. Technology developers can submit dcm0nstratiou proposals any time throughout the year. For each technology sekx,1Cd, EPA, often "ith input from state and regional ag~ncies . dc,e;:.thc following: Identifies a site ,,;ith wastes suitable for treatment • Prepares a technology demonstration plan Notifies appropriate agcn:ies for intergov,,mn :,~,,ta! and -~ conun~ty revit:ws Pr~pares a fact shcct for the public, proposing the ,ite and technology match Prepares the demonstration site Conducts and audits field sampling and laboratory analyses Organizes a Visitors' Daytoviewthetechuologydemonstra- tion Evaluates technology performance Prepares an Applications Analysis Report and a Technology Evaluation _Report summarizing the demonstration results, as well as several other informational items such as bulletins, swnmaries, and a video CONTAMINATED MATERIALS ·----· OR SCREENED SOILS SCREW CONVEYOR MEOUIM TEMP.

Based on the process requirements of the BCD technology, ETG and SRS have developed the SAREX" IBERM-O-DETOX™ system in cooperation with EPA to evaluate the effectiveness of this process under real-time conditions in the field. TheSAREX"lHERM-O-DETOX™systemisbasedonaproven indirect-heat medium temperature them,al desorption (MTTD) unit. The unit is equipped with a multiple-shaft agitator for high heat transfer efficiency and excellent local mixing action. The BCD physicaVchemical process detoxifies and chemically · decomposes contaminants by removing chlorine atoms. Com- pounds that the BCD process can decompose include polychlori- nated biphenyls (PCB), PCP, chlorinated dibenzodioxins and furans, insecticides, and herbicides. The pr~s begins by mixing an inorganic reagent with the contaminated soil, sediment, or sludge. The mixture is heated in the MTTD unit for about 1 hour at 6.50 °F to 800 °F. Some of the chlorinated contaminants are decomposed during this step. The remaining organic contaminants are thermally desorbed and re- moved \\ith the off-gas. Clean soil exiting the solid reactor can be returned to the site. The remaining contaminants from the vapor condensate and residual dust are captured and treated for 2 to 4 hours at approximately 650 °F in a liquid-tank reactor (L TR). The L TR uses a high- . boiling-point hydrocarbon, a proprietary catalyst, and sodium hydroxide. Nitrogen is purged through the L TR to control oxygen levels, preventing the tank contents from oxidizing or igniting. · Oily residuals remaining in the L TR contain dust and sludge and are combustible. They can be burned in an oil-fired power plant, a cement kiln, or treated and reclaimed by waste oil recyclers. The aqueous condensate from the process can be discharged to a publicly·<l\vned treatment works after being polished through an activated carbon treatment process. Decontaminated sludge can be disposed of in the same manner as municipal sludge. Spent carbon from the water polishing can also be treated in this process. The only by-products produced by the BCD process are biphenyl, low-boiling olefinics, and sodium chloride. SITE DESCRIPTION The Koppers Company site is located in the Shiloh community, several miles north ofMorrisville, North Carolina. The site covers approxin1ately 52 acres at the intersection of Highway 54 and Koppers Road (see Figure 2). The southeastern section of the sll: the CELLON processing · area and former lagoon area. The CELLON process involved pressure-treating wood with PCP and then steaming it The water generated from this process, called rinsate, was collected, pro- cessed to remove the PCP by flocculation, and placed in two lagoons at the site for further treatment The rinsate did however contain PCP: The CELLON process was used at the site from . :. !968to 1975. Thetwolagoonswereclosedandemptiedin 1976. -: Water from the lagoons was sprayed onto the ground at the north ··· endofthesite,andthebottomsludgesfromthelagoonswerespread to dry. In 1980, high levels of PCP were found in the soils in the former lagoon area and CELLON processing area. PCP was alsodeiected in the groundwater. In I 989 thesitev.'aS added toEPA's National Priorities List (NPL). A remedial investigation (RI) V.'aS con- ducted, identifying the primary contaminants at the site as PCP, polychlorinated dibenzo-p-<lioxins (PCDD), polychlorinated dibenzofurans (PCDF), and isopropyl . ether (IPE). The RI indicated that the CELLON processing area and lagoon area served as sources for the migration of contaminants into the ground:-,,ater. TECHNOLIY DEMONSTRATION The BCD technology and SAREX® THERM-0-DETO)I."™ sys- tem demonstration at the Koppers Company site is scheduled to occur during August 1993. The primary objectives of this demonstration are to: • Determine how efficiently the BCD process removes PCP, dioxins, and furans from the contaminated soil Determine whether treatment residuals (air, water, oil) meet cleanup levels Evaluate the potential for the BCD process to form additional · volatile organic compounds when heated to high tempera-· tures Obtain information required to estimate treatment cost.s, including capital and operating expenses, for future S uperfund decision-making purposes CHURCH ROAD LEGEND • EXISTING WELLS · -PROPERTY BOUNDARY UNIT STRUCTURES/ KOPPERS SITE PROPERTY LINE > t; ..

The site covers approximately 52 acres at the intersection or' Highway 54 and Koppers Road . (see Figure 2). ETG's BCD technology and the SAREX"' THERM-0-DETOX'" system are heing demonstrated at the Koppers Company site in August 1993. Historv • II a ii " The Koppers Company site is a former wood treating facility. In 1961 the site was sold hy Cary Lumher Company to Unit Structures. Inc. and again sold in 1962 to Koppers Company. In 1986. the majority of the site was sold to Unit Structures (unrelated to the previously mentioned.Unit Structures. Inc.). In 1988 Koppers Company was bought hy Beazer East. Inc. (Beazer). Between 1968 until 1975 a process called CELLON was used to treat wood in the southeastern section of the site. The area is called the CELLON proce,sing area and the · former lagoon area on Figure 2. The treatment consisted of steaming the wood after pentachlorophenol (PCP) had heen·pressure-applied to the wood. Water generated from the steam. known as rinsate. was collected and processed to remove the PCP hy means of flocculation. The rinsate was then placed in two lagoons on the site for further treatment; however. the rinal rinsate did contain amounts of PCP. In I 976. the two lagoons at the site were closed. The water from the lagoons was sprayed onto the ground at the north end of the site. and the lagoon hottom sludges were mixed with surrounding soil anti spread to dry in the former lagoon area. Both areas were fertilized and seeded. In I 980. high levels of PCP were found in the soils of the former lagoon area and the CELLON processing area. PCP was also detected in the groundwater. During several separate actions hetween 1980 and 1986. llver 1.710 cuhic yards of contaminated soil was removed from the area hy Koppers Companv. Contaminated soil was reportedly hauled to a permitted facilitv for proper disposal. 6 l ' .,·1 I 7 I I I • • Demonstration Site CHURCH ROAD OW-2 • • ...

This was finalized in March 1989. In December 1992 the Record of Decision (ROD) was signed. A primary and contingency remedy was selected for soils. The primary remedy cnnsists of soil excavation and off site incineration. The contingency remedy consists of using the BCD technology. For groundwater at the site. carbon adsorption was selected. For surface water at the site. pond dt!watering was chosen. ■ Treatability studies of the BCD process will he conducted on soils at the site. Based on the results from these studies. the BCD technology may be selected to remediate the site.

North Carolina 27511 s I ,.I . I I • • Technology Background ■ EPA's Risk Reduction Engineering Laboratory (RREL) in Cincinnati. Ohio developed and patented the BCD technology. ETG and Separation and Recovery Systems, Inc. (SRS) developed the SAREX"' THERM-0-DETOX" system to be used with the BCD technology. • Through a cooperative effort between the EPA SITE Program. EPA Region 4. the NC-DEHNR. the BCD technology will he evaluated at the Koppers Company Superfund site in Morrisville. North Carolina. The technology demonstration will determine how d'fectively the BCD technology, in conjunction with the SAREX"' THERM-0-DETOX" system. removes PCP and furans from the soil at the site. Prnce.~s Description " The BCD physical/chemical process detoxifies and chemically decomposes contaminants by removing chlorine atoms. The BCD process can decompose polychlorinated biphenyls (PCB). PCP. chlorinated dibenzodioxins and furans. insecticides. and herbicides. " The SAREX"' THERM-0-DETOX" system is based on indirect-heat t,y low and medium temperature thermal desorption (L TTD and MTTD) units. The units are equipped with a multiple-shaft agitator for high heat transfer efficiency, excellent local mixing action. and retention-time variability (see Figure 3). • The process tiegins tiy mixing an inorganic dechlorination reagent with the contaminated soil. sediment. or sludge. The mixture is heated in the MTTD unit for about I hour at 650 °F to 800 °F. Some ot' the chlorinated contaminants are decomposed during this step. The remaining organic contaminants are thermally desorhed and removed with the off-gas. "' Clean soil exiting the MTTD can he returned to the site. The remaining contaminants from the vapor condensate and residual dust are captured and treated for 2 to 4 hours at about 650 °F in a liquid-tank reactor (L TR). The LTR uses a high-boiling-point hydrocarbon. a proprietary catalyst. and sodium hydroxide. Nitrogen is purged through the LTR to control oxygen levels. preventing thl! tank contents from oxidizing or igniting. 9 Technology CONTAMINATED MATERIALS OR SCREENED SOILS • • VAPOR RECOVERY SYSTEM ~----------, FEED J--, DE';,HLO'l:~t•ON VAPOR DISCHARGES HOPPER ~ EAG S I/-Z:/"-/"-d LOW TEMP.

They can be burned in an oil-tired power plant. a cement kiln. or treated and reclaimed by waste oil recyclers. The aqueous condensate from the process can be discharged to a publicly-owned treatment works after being pumped through an activated carbon treatment process. Decontaminated sludge can he Jisposed of in the same manner as municipal sludge. Spent carbon from the water pDlishing can also be treated in this process. ■ The only by-products produced hy the BCD process are nonchlorinated hydrocarbons. low-boiling olefinics. and sodium chloride. BCD Chemistry The base-catalyzed reaction to dehalogenate halogenated compounds can he generalized as follows: R-(Cl)x + R' R - H + NaCl R" • • • catalyst R-(CI). represents halogenated compounds such as PCP. PCBs . 2.4-dichlorophenoxyactic or 2_4.5-trichlorophenol. and dioxins. R' represents the hydrogen donor. Chloride on R-(CI\ is replaced by H to produce R-H. R' donates hydrogen and becomes R'' with the formation of sodium chloride (NaCl). This reaction completely clehalogenates halogenated rnmpounds . 11 • • Technology Equipment II The system includes the following components: (I) a medium-temperature thermal desorption (MTID) unit. (2) a vapor recovery system. and (3) a liquid-tank reactor (L TR). (see Figure 3). 11 Off-gas emissions are extremely low. and organic vapors are condensed and removed. The technology has minimum environmental impact and few permitting requirements. II The treated soil discharged from the MTID unit is free of organic rnntaminants. maintains its physical characteristics. and is suitable for on-site hackiill. " The system can he installed on two to three trailers for ease of mobilization. Operation ■ The system will be demonstrated over a period of 3 weeks. Because this is a pilot-scale remediation. ETG will vary the operating parameters during the technology demonstration to determine optimal conditions for the project. ■ Operating temperature. teed rate. reagents. and off-gas !low rate will he predetermined for each of the six test runs. Factors Affecting Performance 11 System performance could be affected hy the following iacrors: • Ot!gree of mixing • Heat transfer • Material temperature • Retention time • Reagent types and quantities ETG Technolouv Contact For more information on the system. please wnract: Dr. Yei-Shong Shieh ETG Envirnnmental.

NC-DEHNR. the technology developers (ETG and SRS), and Beazer (Koppers Company's owner). • Assess the technology's ability to treat contaminated soil to levels determined in the site's ROD • Determine whether process eftluents meet applicable local. state. and federal standards for disposal or discharge • Evaluate potential effects on PCP and t't,rans. such as formation of other hazardous by-products resulting from the thermal reactions of chemicals in the BCD process. • Develop capital and operating cost estimates • Identify specific operating and maintenance concerns .that may affect the system's long-term reliability Demonstration Prouram Test Runs ■ A total of eight test runs will he conducted to attain the above objectives. six runs using the solids reactor and two runs using the liquid reactor. 11 Operating conditions for the first four solids runs will he varied slightly to determine which exhibit the greatest contaminant reduction and meet cleanup levels. The last two solids runs will use the optimum operating conditions determined during the first four solids runs. Sampling and Analvsis Program 11 The overall sampling objective is to produce well-documented. defensible data that are of known quality and are reproducible. Fnr this reason. EPA prepared a Category II quality assurance project plan (QAPP) that details sampling. analytical. quality assurance. and quality control procedures. Speciti.: sampling objectives are as follows: • Collect samples that are representative of the sampled media • Collect and analyze samples for target compounds necessary to determine the BCD system's performance • Verify the reproducibility of the treatment system's performance • Demonstration Approach Sampling and Measurement Locations • II • Locations at which samples will be collected are discribed in Table-I and shown in Figure 4 . These samples will be analyzed for the target compounds and physical characteristics (for example moisture content I needed to document the system's performance. Various process measurements will be recorded on log sheets to document the operating conditions during each run. Examples of these measurements include waste ieed rate and reactor temperature. The process conditions to he varied include the temperature settings of the solids reactors and the addition of the catalyst. The low temperature and medium temperature thermal desorption units will operate at the same temperature. During test run I :ind 2 they will be Dperated at 800 "F. and during test runs 3 and 4 they will operate at 650 "F. The catalyst will be added during runs I and 3. Oualitv Assurance Ohjectives and Audits • The quality assurance objective for this demonstration is to produce well-documented data of .known quality. Quality is measured by the data's.prec:ision.,accuracy, completeness. representativeness. and comparability. EPA will audit both the field demonstration and the laboratory analvsis to verifv the following: · · - The sampling. analytical. quality assurance. and quality control procedures from the ·approved quality assurance proje·~t plan (QAPP) are properly implemented Modifications to the approved field or laboratory procedures are appropriate 1-l I I I I t • • Demonstration Approach Table 1 -Sampling Locations and Descriptions Sampling De."icription Location I Comaminatt'd soil afler si:.e rt>d11c1ion.

The following site-specific health and safety provisions have been developed · for use during the Koppers site Superfund Innovative Technology Evaluation (SITE) BCD demonstration. This document addresses those items specified under Occupational Health and Safety Administration (OSHA) 29 Code of Federal Regulations (CFR) 1910.120 (b) Final Rule. This document will be provided to all PRC on-site personnel, subcontractors, and site visitors who may be exposed to hazardous conditions during the SITE BCD demonstration. The purpose of the health and safety plan (HSP) is to define requirements and designate the protocols to be followed during the SITE BCD demonstration at the Koppers site. All PRC personnel on site, including PRC employees, subcontractor employees, and site visitors must be informed of site emergency response procedures and any potential fire, explosion, health, or safety hazards of on-site activities. This HSP summarizes potential hazards and defines protective measures planned for site activities. A separate SITE demonstration, to be performed simultaneously with the BCD demonstration, will also be conducted at the Koppers site. This HSP only applies to the SITE BCD demonstration to be conducted at the Koppers site. This plan must be reviewed and approved by the PRC health and safety director (HSD), the PRC project manager, and the EPA Technical Project Manager (TPM). The compliance agreement form in Attachment A must be signed by all field personnel before they enter the site. Any revisions to this plan must be reviewed by the EPA TPM and approved by the PRC HSD. 2.0 HEALTH AND SAFETY PLAN ENFORCEMENT This section describes the responsibilities of project personnel and summarizes requirements for subcontractors and visitors who wish to enter the Koppers site. 1 • • 2.1 PROJECT PERSONNEL The PRC project manager, field site manager, HSD, and site health and safety officer (SHSO) will be responsible for implementation and enforcement of the health and safety provisions of this HSP. Their duties are described in the following sections. 2.1.1 Project Manager and Field Site Manager The PRC project manager, Robert Hutcheson, is ultimately responsible for ensuring that all project participants abide by the requirements set forth in this plan.

The SHSO will have advanced field work experience and will be familiar with health and safety requirements specific to the project. The SHSO will ensure that the Safety Meeting Sign-off Sheet (Attachment B) will be signed by all personnel who are to perform field work. The SHSO must also ensure that each field worker completes a Daily Site Log (Attachment C) before leaving the site. 2.2 SUBCONTRACTORS Subcontractor personnel participating in the SITE demonstration will be required to read and comply with all sections of this plan. All subcontractor personnel entering the site must sign the compliance agreement form. Subcontractor personnel must comply with all applicable OSHA CPR 1910.120 training, fit testing, and medical surveillance requirements. Subcontractors are responsible for providing personal protective equipment (PPE) required by this plan for their personnel (see Section 6.2, Protective Equipment and Clothing), and are ultimately responsible for the health and safety of their employees. 2.3 VISITORS Any visitor to PRC operations at the site will be required to read the PRC HSP and sign the compliance agreement form. Each visitor will be expected to comply with relevant OSHA requirements. Each visitor will also be expected to provide their own personal protection equipment (PPE) required by the HSP. Any visitor who does not adhere to the provisions of the HSP will be ordered to leave the work area. Any visitor who has not met OSHA training and medical surveillance requirements will not be permitted to enter areas where exposure to hazardous materials is possible. Exceptions will be strongly discouraged, but they can be made on a case-by-case basis under the following conditions: (1) respirators are not required, (2) the visitors' time on site is limited, (3) each visitor is given a pre-entry briefing, (4) each visitor is accompanied by trained personnel at all times, and (5) SHSO approval is obtained. 3 • 3.0 SITE BACKGROUND Past investigations have determined that wood treating processes conducted at the Koppers site from 1968 to 1975 contaminated site groundwater, surface water, and soil with pentachlorophenol (PCP), 2,4- dichlorophenol, isopropyl ether (IPE), and other organic contaminants. The following sections describe the Koppers site and its history. 3.1 SITE DESCRIPTION The Koppers site (Figure 3-1) is located in Morrisville, North Carolina, at the intersection of Highway 54 and Koppers Road. The site property currently is owned by two companies, Beazer East Inc. (Beazer) and Unit Structures Inc. (USI). The portion of the site owned by Beazer is inactive. The portion of the site owned by USI currently is used as a wood laminating facility. The site occupies approximately 52 acres and includes the wood laminating facility, an office, and several warehouses (Figure 3-2). Surrounding land is used for a mixture of commercial, light industrial, and rural residential purposes. 3.2 SITE msTORY From 1896 to 1961, the site property was owned by the Cary Lumber Company. In 1961, the site property was sold to USI. The company operations, however, were different than those of US! today. In 1962, the site property· was sold to Koppers. In 1968, Koppers began treating wood using the CELLON® process. This process consisted of injecting PCP into the wood. Butane was used as the carrier solvent. IPE was used as a co-solvent to increase the solubility of the PCP in butane. After application, the butane carrier was evaporated under reduced pressure, leaving a dry, crystalline salt residual of PCP. After the butane carrier was removed, a vacuum was pulled on the cylinder and the IPE and dissolved PCP were sent to a blowdown pit. The PCP residual on the treated wood was removed by steaming. Then the steam condensate was pumped to an aboveground flocculation tanks where flocculent was added to remove the PCP. After flocculation, the condensate passed through a sand filter before emptying into two unlined lagoons located on the property. The CELLON® process was discontinued in 1975, when Koppers began using pre-treated wood for their operations. 4 • • Some time after 1975, the name of the facility was changed from Koppers to Beazer. In 1986, Beazer sold a portion of the site property to US!. USI sold certain portions of the site back to Beazer in 1992. In 1976, Beazer began conducting environmental investigations of the CELLON® process area and the two lagoons. In 1977, as part of their reclamation project, the liquid contents of the two lagoons were pumped out and sprayed on the northern portion of the site. Fertilizer was added to the soils in this area and the soils were plowed. This area is now referred to as the land farm area. The bottom sludges in the lagoons were mixed with the soil surrounding the lagoons and spread out to dry. This area was fertilized and seeded. It is now referred to as the former lagoon area. Beginning in 1980, Beazer began conducting additional environmental investigations at the site. These investigations focused on both soil and groundwater. As a result of the investigations, Beazer removed about 220 cubic yards of soil from the former lagoon area in the spring of 1980. Later that year, Koppers removed an additional 240 cubic yards of soil from the former lagoon area. In 1986, soil was removed from the following areas: 1100 cubic yards from the former lagoon area, 50 cubic yards from the filter bed area, and 100 cubic yards from the blowdown pit area. According to Beazer, the removed soils were disposed of at permitted disposal facilities. In 1986, Beazer began sampling nearby residential wells to determine if the PCP had migrated off site. Also in 1986, the North Carolina Division of Health Services' (NCDOH), Superfund Branch, began to investigate the groundwater in the vicinity of the site. Some of the nearby residential wells showed detectable amounts of PCP and !PE. Beazer provided bottled water to residents whose wells showed detectable levels. Later, Beazer connected most of the residents to the city water system. Beazer and NCDOH, under a cooperative agreement, have continued to sample off-site residential wells on a quarterly basis. The NCDOH Superfund Branch developed a Hazard Ranking System (HRS) package of the site. On June 24, 1988, the site, based largely on its groundwater contamination, was proposed for inclusion on the National Priority List (NPL). The final rule and inclusion of the Koppers site on the NPL list occurred on March 31, 1989. 7 I • In March of 1989, EPA and Beazer signed an Administrative Order on Consent, which permitted Beazer to conduct its own Remedial Investigation/Feasibility Study (RI/FS) on the site. The RI/FS work plan was approved in November 1989 and the field work was started in 1990. The RI/FS field work covered site soils, groundwater, drainage pathways, and ponds. 4.0 SITE-SPECIFIC HAZARD EVALUATION PCP, 2,4-dichlorophenol, isopropyl ether, and 2,3, 7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 2,3, 7 ,8- tetrachlorodibenzofuran (TCDF), commonly referred to as dioxins, are the potential chemical contaminants expected to be encountered during field activities. Field activities to be performed during the SITE demonstration consist of soil sampling and sampling of oil and water from the treatment unit air scrubber system. In addition, sodium hydroxide and sodium bicarbonate, reagents which will be mixed with the soil prior to treatment, may be encountered during soil sampling. Hazardous materials expected to be encountered and a work task hazard analysis are provided in Tables 4-1 and 4-2, respectively. Table 4-3 presents additional hazards that may or may not be encountered during site activities. The material safety data sheets (MSDS) and Registry of Toxic Effects of Chemical Substances (RTECS) information included in Attachment D summarize toxicological, human health, and safety information for the expected contaminants. The following sections describe the possible exposure pathways and health effects of PCP and dioxins. 4.1 EXPOSURE PATHWAYS Exposure to on-site contaminants during field activities may occur through inhalation due to airborne contaminated dust and organic vapors, dermal contact, or ingestion. Descriptions of these exposure pathways are provided below. Exposure to sodium bicarbonate and sodium hydroxide may occur through inhalation and dermal contact during sampling of the soil-reagent mixture. 4.1.1 Inhalation A principal pathway of exposure to PCP, 2 ,4-dichlorophenol, and dioxins during this SITE demonstration is through inhalation of airborne dust contaminated with these compounds. PCP, 2,4-dichlorophenol, and dioxin concentrations in contaminated soil are known to be as high as 3,220 milligrams per kilogram 8 Substance PCP TCDD/TCDF 2,4-dichlorophenol Sodium Hydroxide 0 • TABLE 4-1 HAZARDOUS MATERIALS POTENTIALLY PRESENT AT KOPPERS SITE Environmental Media• Soil Soil Soil Soil Exposure Pathways Inhalation Skin Contact Ingestion Inhalation Skin Contact Ingestion Inhalation Skin Contact Ingestion Ingestion Skin Contact Inhalation 9 Toxic Characteristics" Eye, skin, and throat irritation, nausea, dizziness, loss of weight, chloracne, bronchitis Chloracne, hepatotoxicity, weight loss, thymic atrophy, suppression of cellular immunity, death, probable human carcinogens Mucous membrane and respiratory tract irritation, severe burns Edematous lips, chin, tongue, necrosis of mucous membranes, pneumonia, burns, tissue corrosion, ulcerations, pulmonary edema, squamous cell carcinoma, death due to shock, asphyxia Substance Sodium Bicarbonate Isopropyl ether Notes: • • TABLE 4-1 ( continued) HAZARDOUS MATERIALS POTENTIALLY PRESENT AT KOPPERS SITE Environmental Media' Soil Soil .

Inhalation of dust will be of concern on a windy day when dust is likely to be created. The potential for inhalation of organic vapors also exists. PRC personnel will monitor the concentration of dust and organic vapors with real-time field survey instrumentation. When appropriate, personal protection will be upgraded to Level C. 4.1.2 Denna! Contact Dermal contact with either contaminated soil or water and oil from the scrubber unit may occur during on-site sampling activities. Dermal contact will be prevented with the use of the proper PPE, such as inner and outer gloves. Safe operating procedures for PPE are described in Section 6.3. 4.1.3 Ingestion Ingestion of hazardous materials, although unlikely, may occur due to lack of proper hygiene or decontamination procedures. Section 9.2 discusses safe work practices that may prevent ingestion of hazardous materials. 4.2 HEALTH EFFECTS The following sections describe the health effects of PCP, 2,4-dichlorophenol, dioxins, !PE, sodium hydroxi\Je, and sodium bicarbonate. Health effect information is taken from the National Institute for Occupational Health and Safety (NIOSH, 1990) handbook and MSDSs. Table 4-4 presents permissible exposure levels (PEL) for chemical exposures to be potentially encountered on site, in accordance with OSHA 29 CFR 1910. Low, medium, or high levels of these contaminants may be encountered during sampling activities at the Koppers site. Potential exposure to contaminated soil or air scrubber water and oil may be through inhalation, skin contact, or ingestion. Effects of acute exposure to PCP include irritation of the eyes, skin, throat, and lungs, rapid heartbeat and breathing, fever, muscle weakness, loss of appetite, sweating, dizziness, and nausea. Very high doses may cause unconsciousness, seizures, and death due to cardiac arrest. Hot weather may increase the risk of acute poisoning. The effects of chronic exposure to PCP may include chloracne, bronchitis, and weight loss. 13 • • TABLE 4-4 PERMISSIBLE EXPOSURE LEVELS FOR ON-SITE CHEMICALS On-Site Chemical PEL Pentachlorophenol (PCP) 0.5 mg/m3 2,3, 7 ,8-tetrachlorodibenzo-p-dioxin (TCDD) None established 2,3, 7,8-tetrachlorodibenzofuran (TCDF) None established 2,4-dichlorophenol None established sodium hydroxide (NaOH) 2.0 mg/m3 sodium bicarbonate (NaHCO3) None established On-Site Chemical TLV isopropyl ether 1,050 mg/m3 14 • • Acute exposure to 2,4-dichlorophenol may result in irritation of the mucous membranes and upper respiratory tract. Prolonged contact may produce severe skin irritation or burns. No chronic symptoms are known to date. Exposure to high concentrations of isopropyl ether vapor may cause drowsiness, dizziness, nausea, vomiting, narcosis, and irritation of the eyes and nose. Repeated or prolonged exposure to the skin may result in drying and irritation of the skin. Ingestion of isopropyl ether causes symptoms similar to those for overexposure to vapor. Chronic exposure may cause headaches, dizziness, weight loss, and intoxication and depression. Acute and chronic effects of 2,3,7,8-TCDD exposure include chloracne, hepatotoxicity, psychological alterations, weight loss, thymic atrophy, gastric ulcers, peripheral neuropathy, thrombocytopenia, suppression of cellular immunity, and death. The liver appears to be the target organ following acute exposure. It should be noted that 2,3,7,8-TCDD is a probable human carcinogen. Ingestion of sodium hydroxide may cause: immediate burning of the mouth, esophagus, and stomach; edematous lips, chin, and tongue; painful swallowing; necrosis of the mucous membranes; vomiting; and a rapid, faint pulse. Death usually results from shock, asphyxia, or pneumonia two or three days after ingestion. Skin contact may not be painful for up to three minutes after contact; however, skin damage begins immediately. Damage may progress to severe burns, tissue corrosion, ulcerations, and permanent scarring if not immediately washed off. Inhalation may cause burns and pulmonary edema. Chronic effects may include squamous cell carcinoma of the esophagus years after ingestion and dermatitis due to repeated exposure. Acute exposure to sodium bicarbonate may result in irritation, and possible chemical burns, of the skin, eyes, and mucous membranes of the respiratory tract. No effects from chronic exposure to sodium bicarbonate have been reported. Worker exposure to on-site contaminated soil will be controlled through proper use of PPE and real-time air monitoring for dust. The need for respiratory protection (powered air purifying respirators) will be based on real-time air monitoring results. Initially, soil samples will be collected in Level C. If the concentration of the dust measured on the monitoring instrument is less than 5 mg/m3, the level of 15 • protection will be downgraded from Level C to Level D. The allowable particulate concentration (APC) was calculated for PCP based on the highest recorded soil concentration of PCP found on site which was found to be approximately 155 mg/m3• The PEL value for PCP is 0.5 mg/m3. PELs for 2,4- dichlorophenol and dioxins have not been established. 4.3 PHYSICAL HAZARDS Physical hazards associated with sampling and other activities present a potential threat to on-site personnel. Dangers are posed by underground utility lines, unseen obstacles, noise, heat, and poor illumination. Injuries may result from the following: • Accidents due to slipping, tripping, or falling • Improper lifting techniques • Moving or rotating equipment • Equipment mobilization and operation (for example, electrocution from contact with underground power lines) • Improperly maintained equipment Injuries resulting from physical hazards can be avoided by adopting safe work practices (SWP) and by using caution when working with machinery. SWPs to be used during on-site sampling are described in Section 9.2. To ensure a safe work place, the SHSO will conduct and document regular safety inspections and will ensure that site workers are informed of potential physical hazards related to the site. 5.0 TRAINING REQUIREMENTS All on-site PRC personnel, subcontractors, and site visitors who may be exposed to hazardous on-site conditions will be required to meet the training requirements outlined in OSHA 29 CFR 1910. 120, which covers hazardous waste operations and emergency response. All PRC personnel and each visitor entering the site will be required to read this HSP and sign the compliance agreement form, and site workers will be required to sign the Safety Meeting Sign-off Sheet. 16 • Before on-site activities begin, a briefing will be presented by the SHSO for all personnel who will participate in on-site activities. The following topics will be addressed during the briefing: • Names of the SHSO and the designated alternate • Site history • Hazardous chemicals that may be encountered during on-site activities • Physical hazards that may be encountered on site • Training requirements • Levels of protection to be used for specific work tasks • Work tasks • Environmental surveillance equipment use and maintenance • Action levels (Section 8.3, Monitoring Parameters) and identification of situations requiring an upgrade or downgrade in levels of protection • Site control measures, including site control zones, communications, and safe work practices (Sections 9.0, Site Control) • Emergency communication signals and codes • Decontamination procedures • Environmental accident emergency procedures (in case contamination spreads outside the exclusion zone) • Personnel exposure and accident emergency procedures (in case of exposure to hazardous substances, falls, and other hazardous situations) • Fire and explosion emergency procedures • Emergency telephone numbers • Emergency routes Other health and safety related topics that may arise before on-site activities begin also will be discussed at the briefing. 17 • Issues that arise during implementation of on-site activities will be addressed during "tailgate" safety meetings to be held daily before the shift begins. Any changes in procedures or site-specific health and safety related matters will be addressed during these meetings. 6.0 PERSONAL PROTECTION REQUIREMENTS PPE will be worn to protect field personnel from known or suspected physical hazards, air-, and soil- borne contamination. The levels of personal protection to be used for work tasks have been selected based on known or anticipated physical hazards, concentrations of contaminants that may be encountered on site, their chemical properties, toxicity, exposure routes, and contaminant matrices. The following sections describe levels of protection, limitations of protective clothing, the duration of work tasks, and respirator selection, use, and maintenance. 6.1 LEVELS OF PROTECTION Personnel will wear personal protective equipment when site activities involve known or suspected atmospheric contamination such as when airborne dust is generated by site activities or accidental direct dermal contact occurs. Full-face powered air purifying respirators will be used to protect the lungs, the gastrointestinal tract, and eyes against airborne contaminants. Chemical-resistant clothing will be used to protect the skin and body parts from direct contact. Levels of protection and their respective components are classified under four categories according to the degrees of protection: Level D: Level C: This level provides minimal protection against chemical hazards. Worn only as a work uniform, worn in areas posing no respiratory or skin hazards. Worn when the criteria described for Level C protection in Section 8. 3 for using air-purifying respirators are met, and a lesser level of skin protection is needed. 18 • Level B: Level A: • Worn when the highest level of respiratory protection is needed, but a lesser level of skin protection is required. Level B is the primary level of choice for unknown environments. PRC does not conduct site activities that require Level A protection. 6.2 PROTECTIVE EQUIPMENT AND CLOTHING The following general levels of protection and the associated PPE ensembles have been selected for use by field personnel during sampling activities (see Table 4-2, Work Task Hazard Analysis). Because the anticipated hazard level is medium, sampling will be performed using Level C protection. If site conditions or the results of air monitoring performed during on-site activities do not warrant Level C protection, all field personnel will downgrade to Level D protection. Descriptions of equipment and clothing required for Levels D and C protection are provided below. It is not anticipated that site activities will warrant Level A or Level B protection. • Level D Coveralls or work clothes, if applicable Steel-toed boots with shanks Hard hat (face shield optional) Disposable outer gloves (latex or nitrile), if applicable Safety glasses or goggles Chemical-resistant clothing (Tyvek® or Saranex®), if applicable Disposable boot covers (when entering wet or muddy areas with known elevated contamination levels, such as previously excavated waste areas) Hearing protection (for areas with a noise level exceeding 85 decibels on the A-weighted scale) • Level C Coveralls or work clothes, if applicable Chemical-resistant clothing (Tyvek® or Saranex®), if applicable 19 • • Outer gloves (neoprene or nitrile}, if applicable Inner gloves (latex or polyvinyl chloride) Steel-toed boots with shanks Disposable boot covers or chemical-resistant outer boots Full-face, air-purifying or powered air-purifying respirator with NIOSH- or Mine Safety and Health Administration (MSHA)-approved cartridges to protect against organic vapors, dust, fumes, and mists (cartridges will be changed at the end of each shift, with increased breathing resistance, or at breakthrough, whichever occurs first) Safety glasses or goggles (with half-face respirator only) Hard hat (face shield optional) Hearing protection (for areas with a noise level exceeding 85 decibels on the A-weighted scale) 6.3 LIMITATIONS OF PROTECTIVE CLOTIIlNG PPE clothing ensembles designated for use during site activities have been selected to provide adequate protection against contaminants at known or anticipated concentrations in soil matrices and ambient air. However, no protective garment, glove, or boot is entirely chemical-resistant, nor does any protective clothing provide protection against all chemicals. Permeation of a given chemical through PPE depends on contaminant concentrations, environmental conditions, the physical condition of the protective garment, and the resistance of the garment to the specific contaminant. Chemical permeation may continue even after the source of contamination has been removed from the garment. To obtain optimum use from PPE, the following procedures will be followed by all site personnel: • When using Tyvek® or Saranex® coveralls, don a new, clean garment after each rest break or at the beginning of each shift. • Inspect all clothing, gloves, and boots both before and during use for the following: --Imperfect seams --Nonuniform coatings --Tears 20 • • --Poorly functioning closures • Inspect reusable garments, boots, and gloves both before and during use for visible signs of chemical permeation such as the following: --Swelling --Discoloration --Stiffness --Brittleness --Cracks --Any sign of puncture --Any sign of abrasion Reusable gloves, boots, or coveralls exhibiting any of the characteristics listed above must be discarded. PPE clothing used in areas with known or suspected elevated concentrations of contaminants should not be reused. Reusable PPE will be decontaminated in accordance with procedures described in Section IO. I and will be neatly stored in the support zone, away from work zones. 6.4 DURATION OF WORK TASKS The duration of site activities involving use of PPE will be established by the SHSO or a designee and will be based on ambient temperature and weather conditions, the capacity of personnel to work in the designated level of PPE (taking into account such conditions as heat stress), and the limitations of the protective equipment. All rest breaks will be taken in the support zone after decontamination and removal of PPE. 6.5 RESPIRATOR SELECTION, USE, AND MAINTENANCE All PRC personnel and subcontractors taking part in site activities must fulfill worker provisions outlined in OSHA 29 CFR 1910.134. PRC and subcontractor personnel will be informed of the proper use, maintenance, and limitations of air-purifying respirators during the daily safety briefing, if applicable. All site personnel must complete a qualitative fit test for the respirator to be used on site. Respirator use is anticipated for the site. If necessary, a full-face, powered air-purifying respirator equipped with NIOSH-or MS HA-approved cartridges will be selected for use to protect against dusts and vapors. Respirators will be selected by the SHSO based on knowledge of the substances that may be 21 • present and the concentrations of compounds previously encountered at the site. Air-purifying respirators will be used only in conjunction with breathing-space air monitoring, which must be conducted in adherence to the action limits outlined in Section 8.1. Air-purifying respirators will be used only when the devices can provide protection against the substances encountered on site. Factors precluding the use of air-purifying respirators are as follows: • Concentrations of substances that may be immediately dangerous to life and health, as defined in the MSDS • High relative humidity (which reduces the sorbent life of the cartridges) • Identified substances with inadequate warning properties (for example, they are tasteless, odorless, and invisible), and respirator cartridges with an unknown sorbent service life, and respirator units with no end-of-service-life indicator Respirators will be inspected daily, and any necessary repairs will be made during the time of inspection. Damaged respirators will be properly disposed of. Respirators issued to individuals will be cleaned and disinfected in the support zone at least weekly. When a respirator is used by more than one person, the respirator will be.cleaned and disinfected after each use. After being cleaned, respirators will be placed in clean plastic bags and stored in the support zone. The following respirator inspection and cleaning procedures will be followed whenever respirator protection is used: • Daily Inspection and Checkout Procedures: Visually inspect the entire unit for obvious damage and deteriorated rubber. Inspect the face-piece harness for damage. Inspect the lens for damage and make sure the face piece has the proper seal. Pull the plastic cover off the exhalation valve and check the valve for debris and tears in the neoprene that could cause leakage. Unscrew the cartridges of both inhalation valves and visually inspect the neoprene valves for tears. Make sure the inhalation valves and cartridge receptacle gaskets are in place. 22 • • Make sure a protective cover is attached to the lens. Make sure the speaking diaphragm retainer ring is hand-tight. Don the respirator, and perform the negative pressure test. • Weekly Cleaning Procedures: Disassemble the respirator in the support zone by removing the cartridges, damaging them to prevent accidental reuse, and discarding them. To clean the respirator thoroughly, remove the inhalation and exhalation valves, speaking diaphragm, and any hoses. To clean the respirator, dissolve cleaning and disinfecting solution (usually provided by the manufacturer) in warm water in an appropriate tub. With gloved hands, swirl the respirator in the tub for at least 1 minute. A soft brush may be used to facilitate cleaning. Rinse the cleaned and disinfected respirator thoroughly with potable water to remove all traces of detergent and disinfectant. This step is very important in preventing dermatitis. Air dry the respirator on a clean surface. The respirator may also be hung upside-down, but care must be taken not to damage or distort the face piece. Reassemble the clean, dry, respirator and inspect it in an area separate from the disassembly area to avoid contamination. Inspect the respirator carefully for detergent or soap residue left by inadequate rinsing. Residue appears most often under the seat of the exhalation valve and can cause valve leakage or sticking. • Procedures to Follow after Routine Use in the Exclusion Zone: Wash and rinse the respirator in the support zone with soap and warm water. At a minimum, wipe the respirator with disinfectant wipes that have been soaked in benzoalkaloid or isopropyl alcohol. Allow the respirator to air dry in the support zone. The effectiveness of the respiratory protection program will be monitored continuously by the SHSO or the SHSO's designee. Monitoring of worker stress levels during activities that require respiratory protection will also be performed by the SHSO or the designee (Section 8.0, Environmental Surveillance). 23 • • 7.0 MEDICAL SURVEILLANCE The following section describes the PRC medical surveillance program, including health monitoring, documentation, record keeping, medical support, and follow-up procedures. This program will be followed for all activities at the Koppers site. 7.1 HEALTH MONITORING REQUlREMENTS All PRC and subcontractor personnel involved in on-site activities at the Koppers site must participate in a medical surveillance program, as required by OSHA 29 CFR 1910.120(1). PRC has established a medical surveillance program with Environmental Medicine Resources, Inc., of Atlanta, Georgia. Under this program, PRC personnel receive annual or biennial physical examinations consisting of the following: • A baseline medical examination that includes the following: Completion of a personal, family, and environmental history questionnaire Physical examination Vision screening Laboratory test Audiometric screening Pulmonary function test Resting electrocardiogram Chest x-ray (required once every 3 years) • A complete blood count that includes the following: White blood count Red blood count Hemoglobin test 24 • Hematocrit test Liver function test Kidney function test Lipid metabolism test Carbohydrate metabolism test • A urinalysis that includes the following: Sugar content test Albumin content test Specific gravity test • Laboratory chemistries for the following: Cholinesterase • Coproporphyrin and uroporphyrin Arsenic Cadmium Iron PRC receives a copy of the examining physician's written opinion after post-examination laboratory tests have been completed; PRC employees also receive a copy of the written opinion. This opinion includes the following information (in accordance with 29 CFR 1910.120(!)(7)): • The results of the medical examination and tests. • The physician's opinion as to whether or not the employee has any medical conditions that would place the employee at an increased risk of health impairment from work in hazardous waste operations or during an emergency response. 25 • • • The physician's recommended limitations, if any, on the employee's assigned work. Special emphasis is placed on fitness for duty, including the ability to wear any required PPE under conditions expected on site (for example, temperature extremes). • A statement that the employee has been informed by the physician of the medical examination results and of any medical conditions that require further examination or treatment. 7.2 DOCUMENTATION AND RECORDKEEPING REQUIREMENTS The PRC Chicago office will maintain medical surveillance records for each PRC employee performing hazardous waste site activities. These records will be in compliance with 29 OSHA CFR 1910.120(!). The records will also be maintained at Environmental Medicine Resources in Atlanta, Georgia. Any visitor or observer at the site will be required to provide documentation of compliance with OSHA 29 CFR 1910.120(!) before entering the site. In addition, PRC will be responsible for recording and reporting accidents, illnesses, and injuries involving PRC employees in accordance with OSHA 29 CFR 1910 and 1926 and EPA requirements. An accident report form, to be completed by the SHSO, is provided in Attachment F. A copy of this completed report will be added to PRC's medical surveillance records in the event of a reportable accident, illness, or injury. 7.3 MEDICAL SUPPORT AND FOLLOW-UP REQUIREMENTS PRC personnel will be required to seek medical attention and physical testing in the event of injury or possible exposure above established exposure limits. Depending upon the type of injury or exposure, follow-up testing, if required, must be performed within 24 to 48 hours of this incident. The type of test to be performed to monitor exposure effects will be based on the circumstances involved and will be selected by a qualified health professional from Environmental Medicine Resources. 8.0 ENVIRONMENTAL SURVEILLANCE Radian Corporation will be on site during the BCD demonstration to conduct air monitoring activities. Radian will monitor gases generated in the reactor at several points in the reactor system. 26 • • Off-gases that have been treated in the reactor unit scrubber system also will be monitored to ensure that the offgas treatment process is effective and toxic gases are not released. Radian will not perform personal air monitoring for workers on site. Air monitoring will be performed by PRC during designated sampling and other on-site activities to protect field personnel against exposure to airborne hazardous substances and to determine appropriate levels of PPE for work tasks. The following sections discuss initial air monitoring, periodic air monitoring, monitoring parameters, use and maintenance of survey equipment, and heat stress monitoring. 8.1 INITIAL AIR MONITORING Initial air monitoring of the work area will be performed before and during the sampling activity. This monitoring activity will be performed using real-time field survey instrumentation, such as a Miniram Model PDM-3 and a Photovac Microtip HL200, to determine the airborne concentrations of site derived dust and organic vapors, respectively. These airborne concentrations will also be monitored at the beginning of each work day to identify background contaminant concentrations and to detect any potentially hazardous situations that might have developed during off-shift periods. 8.2 PERIODIC AIR MONITORING Periodic air monitoring will be performed during all site activities. This type of monitoring will be performed as a minimum requirement when the following situations arise: • Work begins on a different portion of the site. • Workers experience physical difficulties. Required survey instrumentation, sampling procedures, and monitoring procedures are specified in Section 8.3. Sampling methods will be subject to review by the SHSO. 27 • • 8.3 MONITORING PARAMETERS Air monitoring for ambient airborne dust and organic vapors will be performed at shoulder height (in the breathing zone) on workers most likely to be exposed to potentially hazardous concentrations of contaminants. Situations that will require air monitoring, monitoring parameters, detection devices, and action levels are discussed below. 8.3.1 Ambient Airborne Dust The following instrument and monitoring frequency will be used to monitor for airborne dust during site activities. • Instrument: • Activity: • Monitoring Frequency: Miniram® Model PDM-3 Direct Real-Time Air Monitoring Monitoring will be performed continuously during on-site activities. Initially, Miniram® readings will be recorded in the field logbook every hour. If continued monitoring does not indicate the presence of airborne dust at or above 5 mglm', readings may be recorded every two hours or longer, based on the SHSO's review of the monitoring data collected. The PEL value of PCP is 0.5 mg/m3• No PEL values for 2,4-dichlorophenol or dioxin have been established. If the dust concentration does not exceed 5.0 mg/m3, the protection level will be downgraded from Level C to Level D. Action levels for on-site dust contaminants are detailed below. • General Action Levels Situation: Concentration of airborne dust are below 5 mg/m3 Action: Continue investigation without respiratory protection at Level D, continue monitoring Situation: Concentration of dust at or above 5 mg/m3 Action: Notify SHSO; upgrade to Level C protection and continue work unless otherwise specified 28 • • 8.3.2 Organic Vapors The following instrument and monitoring frequency will be used to monitor for organic vapors during site activities. • Instrument: • Activity: • Monitoring Frequency: Photovac Microtip HL-200 equipped with a 10.6 electron voltage lamp Direct Real-Time Air Monitoring Monitoring will be performed continuously during on-site activities. Initially, Microtip readings will be recorded in the field logbook every 30 minutes. If continued monitoring does not indicate the presence of organic vapors, readings may be recorded every hour or longer based on the SHSO's review of the monitoring data collected. Individual concentrations of organic vapors of concern will not be determined by field instruments because mixtures of organic vapors may be encountered and real-time field survey instrumentation may react to the total organic vapor mixture (by measuring positive interference, or giving a false-positive reading). Action levels for organic vapors are detailed below. • General Action Levels .Situation: Concentration at background concentration to 5 parts per million (ppm) above background concentration Action: Continue investigation without respiratory protection at Level D; continue monitoring Situation: Concentration 5 ppm to 25 ppm above background concentration Action: Notify SHSO; upgrade to Level C protection and continue work unless otherwise specified Situation: Concentration 25 ppm to 500 ppm above background concentration Action: Notify SHSO; evacuate exclusion zone; consult HSD about whether or not to continue site activities 29 • • 8.4 USE AND MAINTENANCE OF SURVEY EQUIPMENT All personnel using field survey equipment will be briefed by the SHSO on its operation, limitations, and maintenance. Maintenance and calibration will be performed in accordance with manufacturer guidelines by a designated individual familiar with the devices. Repairs, maintenance, and routine calibration of these devices will be recorded in an equipment maintenance logbook that will be signed by the service technician. The equipment maintenance logbook for each instrument will be kept in that instrument's case. Air monitoring equipment (such as the Miniram®) will be calibrated before work begins and at the end of the work day. Only routine maintenance (such as changing batteries and fans) will be performed by on-site personnel. Any additional maintenance will be performed by a trained service technician. 8.5 HEAT STRESS MONITORING Heat stress is a common and serious illness at hazardous waste sites. Occurrence of heat stress depends on such factors as environmental conditions, clothing, workload, an on-site worker's physical condition and characteristics, and the type of PPE required for the work task. Some types of PPE are water impermeable and heavy and may lead to potential heat stress conditions. Under heat stress conditions, the body's expenditure of energy increases and reduces the efficiency of the body's normal heat exchange mechanisms. Heat stress may be of particular concern when the dry-bulb air temperature exceeds 70°F. Depending on the degree and nature of possible heat stress to be encountered on site, the SHSO will choose from the following heat stress control actions: • Provide adequate liquids to replace lost body fluids. These liquids may be water, commercial mixes combined with potable water, or commercial liquids (such as Gatorade®). • Establish a work regimen that will provide adequate rest periods for cooling down. This action may require additional shifts for workers or earlier or later work schedules. 30 • • • Provide cooling devices, such as vortex tubes or cooling vests, to be worn beneath protective garments. • Require removal of impermeable protective garments during rest periods. • Ensure that all rest periods are taken in a shaded rest area, if possible. • Regulate rest periods, and ensure that workers will not be assigned other tasks during rest periods. • Notify all workers of health hazards and the importance of adequate rest, acclimatization, and proper diet; teach workers to recognize heat stress and to conduct first aid to prevent heat stress. The following chart contains general guidelines that can be used to pace hot-weather field work: Continuous Work 75 percent work and 25 percent rest each hour 50 percent work and 50 percent rest each hour 25 percent work and 75 percent rest each hour Light Work 82.4 83.5 84.9 86.4 Wet Bulb Globe Temperature' Degrees Fahrenheit {°F) Moderate Work 76.5 78.8 81.4 84.4 Heavy Work 73.4 75.0 78.6 82.4 ' Temperature adjusted for worker wearing coveralls. Subtract 5 degrees for water impervious clothing. Source: Modified from ACGIH 1990. Higher heat exposures than those shown above are permitted if workers have undergone medical surveillance and if it has been established that they are more tolerant of hot-weather work than an average worker. Workers will not be permitted to continue work when deep body temperatures exceed 100 .4 "F. If the SHSO determines that heat stress is a potential problem, body temperatures will be monitored periodically to ensure that overheating does not occur. 31 • • 9.0 SITE CONTROL Work areas on or near the site will, depending on environmental monitoring, be divided into an exclusion zone, a contamination reduction zone (CRZ), also known as decontamination zone, and a support zone. Generally, the exclusion zone will be designated by barricade tape or traffic cones. Access to a contaminated exclusion zone will be restricted to authorized personnel. A daily roster with the date of each person's entrance into the contaminated zone; the person's name, signature, and organization; the time of entry; and the time of exit will be kept for all personnel working in such an area. Any visitors to the area must present proper identification and be authorized for site entry. Visitors must comply with all provisions of this HSP. The SHSO will identify work areas that visitors or personnel are authorized to enter and will enforce site control measures. The following sections discuss site SWPs, HSP enforcement, and complaints. 9.1 COMMUNICATIONS The following hand signals will be employed by site personnel in emergency situations or when verbal communication is difficult. Signal Hands clutching throat Hands on top of head Thumbs up Thumbs down Arms waving upright Gripping partner's wrist 9.2 SAFE WORK PRACTICES Definition Out of air or cannot breathe Need assistance Okay, I am all right, or I understand No or negative Send backup support Exit area immediately Safe Work Practices (SWP) requirements for site activities include the following: 32 • • • All site personnel will enter a designated exclusion zone only through the contamination reduction corridor (CRC). All personnel leaving an exclusion zone must exit through the CRC and undergo the CRZ decontamination procedure. • Only equipment necessary to complete sampling will be permitted within an exclusion zone. All nonessential equipment will remain within the support zone. • All personnel will avoid contact with potentially contaminated substances. Walking through puddles or mud and kneeling on the ground will be avoided whenever possible. • Equipment will not be placed on potentially contaminated surfaces. • Food and beverages will not be permitted in the exclusion zone or CRZ. Possession or use of tobacco products and application of cosmetics are also prohibited in these areas. • Matches and lighters will not be permitted in the exclusion zone or CRZ. • During rest periods, all personnel will be required to observe each other for signs of toxic exposure and heat stress. Indications of adverse effects include, but are not limited to, the following: Changes in complexion and skin discoloration Changes in coordination Changes in demeanor Excessive salivation and pupillary response Changes in speech patterns • Site personnel will inform each other of nonvisual effects of illness, such as the following: Headache Dizziness Nausea Blurred vision Cramps Irritation of eyes, skin, or the respiratory tract The following sections describe safe work practices regarding sampling in trenches and confined spaces, avoidance of trip and fall hazards, site activities near utility and power Jines, avoidance of excessive noise exposure, ilJumination, sanitation, and site housekeeping. 33 • 9.2.1 Sampling in Trenches and Confined Spaces Sampling in trenches and excavations may pose physical hazards to personnel. The following precautions will be taken when sampling is conducted in excavations or trenches. • Trenches will be inspected by a competent person before workers enter them. A confined space entry permit system will be used to prevent workers from entering unsafe trenches. • Workers will not enter trenches alone. Standby personnel will always be present to respond in the event of an emergency. • The level of protection for entry personnel will be based on the results of air monitoring. • If the depth of the water present in trenches and excavations is 3 feet or above, sampling will not be conducted in those areas. All site personnel entering confined spaces will observe requirements specified in ANSI Z 117 .1-1977 (or the latest version). Each worker must complete a Confined Space Entry Permit for each confined space to be entered. This form (Attachment E), must be approved by the SHSO before work in the confined space begins. Before entry, a worker must have satisfactorily completed a confined space training program and a Confined Space Entry Permit. It is not anticipated that site activities will require confined space entry. 9.2.2 Avoidance of Trips and Falls Workers will be informed of any potential trip and fall hazards during regular health and safety meetings. Whenever possible, trip and fall hazards will be eliminated or clearly identified with yellow caution tape. 9.2.3 Site Activities Near Utility and Power Lines Site activities will proceed with caution in any area where historical data or instrument surveys indicate the presence of utility lines (such as gas, telephone, and other lines). All site activity locations will be coordinated by the PRC project manager. 34 • • 9.2.4 Avoidance of Excessive Noise Exposure Workers will be protected from excessive noise exposure by means of equipment maintenance, noise monitoring, and hearing conservation programs that comply with OSHA 29 CFR 1910.95. Hearing protection will be required if the sound level continuously equals or exceeds 85 decibels on the A- weighted scale or if the sound level exceeds 140 decibels regardless of the duration of exposure. Sound level will be measured with a sound level meter during site activities. The decibel level will be measured using a slow response setting on the A-weighted scale. Ear inserts with a noise reduction rating of at least 26 decibels on the A-weighted scale or similar equipment will be provided to PRC personnel. Such equipment will be worn during work tasks involving heavy equipment, internal combustion engines, or other sources of elevated noise levels. 9.2.5 Illumination Outdoor work will not be performed after sunset or when a lack of artificial or natural illumination makes outdoor work difficult. 9.2.6 Sanitation Potable water, drinking cups, nonpotable water, toilet facilities, washing facilities, and other sanitation requirements will be provided in compliance with specifications of OSHA 29 CFR 1910.120(n). 9.2. 7 Site Housekeeping Potentially hazardous wastes generated during site activities will be double bagged and drummed, if necessary, and handled in accordance with Resource Conservation and Recovery Act (RCRA) requirements. Nonhazardous waste and debris will be disposed of as standard municipal waste. 35 • • 9.3 HEALTH AND SAFETY PLAN ENFORCEMENT The SHSO will be responsible for enforcement of the HSP during on-site sampling activities. Personnel who fail to follow HSP procedures will face disciplinary action that may, at a maximum, include dismissal from the site. At least one copy of this HSP will be available to all site personnel at all times. Any necessary changes in HSP procedures will be made at the beginning of each work day by the SHSO. 9.4 COMPLAINTS Personnel will be encouraged to report to the SHSO any conditions or practices that they consider detrimental to their health or safety or that they believe are in violation of applicable health and safety standards. Such complaints may be made orally or in writing. Personnel who believe that an imminent danger threatens human health or the environment will be encouraged to bring the matter to the immediate attention of the SHSO for resolution. 10.0 DECONTAMINATION Decontamination is the process of removing or neutralizing contaminants from personnel or equipment. When properly conducted, decontamination procedures protect the worker from contaminants that may have accumulated on PPE, tools, and other equipment. Proper decontamination also prevents transport of potentially harmful materials to unaffected areas. Personnel and equipment decontamination procedures are described in the following sections. 10.1 PERSONNEL DECONTAMINATION Minimal personnel decontamination is anticipated for the Koppers site because disposable PPE will be used. If necessary, personnel decontamination will be completed according to the guidance given in the "Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities" (NIOSH 1985). Personnel and PPE will be decontaminated with potable water or a mixture of detergent and water. Liquid and solid wastes produced during decontamination will be collected, drummed, and disposed of 36 • • pending on-site analysis. If accepted, decontamination wastes will be disposed at the POTW. If decontamination wastes are not accepted at the POTW, a licensed disposal contractor will be hired for decontamination waste removal. The following decontamination procedures will be conducted if personnel decontamination is required: • Wash neoprene boots ( or disposable booties) with a Liquinox® or Alconox® solution, and rinse them with water. Remove and retain neoprene boots for reuse, if possible. Place disposable booties in plastic bags for disposal. • Wash outer gloves in a Liquinox® or Alconox® solution and rinse them in water. Remove outer gloves and place them in a plastic bag for disposal. • Remove the Tyvek® or Saranex® suit and place it in a plastic bag for disposal. • Remove the air-purifying respirator, if used, and place the spent filter in a plastic bag for disposal. The filter may be changed daily or at longer intervals, depending on the use and application. Clean and disinfect the respirator with towelettes or a non-phosphate cleaning solution. Place it in a plastic bag for storage. • Remove inner gloves and place them in a plastic bag for disposal. • Thoroughly wash hands and face with water and soap. Used, disposable PPE will be collected in 55-gallon drums and disposed of as municipal waste, unless otherwise specified. Further personnel decontamination procedures may be established as needed. 10.2 EQUIPMENT DECONTAMINATION Decontamination of all nondisposable sampling and field monitoring equipment used during site activities will be required. The equipment decontamination procedures described in the following sections are based on guidelines appropriate for low-level contamination. When appropriate, Liquinox® or Alconox® cleaning solutions and deionized water rinses will be used to decontaminate equipment. Wastewater from equipment decontamination activities will be disposed of in the same manner as personnel decontamination wastes, as discussed in Section IO. I. 37 • • 10.2.1 Sampling Equipment Sampling equipment such as stainless steel spades, spoons, soil and groundwater samplers, and stainless steel or aluminum pans will be decontaminated before and after each use. Distilled water will be used for the following sampling equipment decontamination procedures: • Scrub the equipment with a brush in a bucket containing Liquinox® or Alconox® solution and potable, distilled water. • Triple-rinse the equipment with distilled water, and allow it to air dry. • Reassemble the equipment and 'place it in a clean area on plastic or aluminum foil. If aluminum foil is used, wrap the equipment with the dull side of the aluminum foil toward the equipment. 10.2.2 Field Monitoring Equipment The Miniram® Model PDM-3 will be used for monitoring concentrations of dust in the atmosphere. This equipment will be cleaned daily by wiping it with isopropyl alcohol wipe. Also, the equipment will be stored in a bag to minimize the exposure to the dust. 11.0 EMERGENCY CONTINGENCY PLANNING The SHSO will be notified of any on-site emergencies and will be responsible for ensuring that appropriate emergency procedures are followed. Standard emergency procedures to be used by site personnel are described in the following sections. 11.1 INJURY IN THE EXCLUSION OR THE CONTAMINATION REDUCTION ZONE In the event of an injury in the exclusion zone or CRZ, all personnel will exit the exclusion zone and assemble at the decontamination line, and the SHSO will be immediately notified of the event if necessary. The SHSO will contact the HSD, and together they will evaluate the nature and extent of the injury. The affected person will be decontaminated to the extent practical before being moved to the support zone. Appropriate first aid procedures will be performed, an immediate request for an ambulance 38 • • will be made (if necessary), and the designated medical facility will be notified (if necessary). Emergency numbers for reaching an ambulance and the designated medical facility are provided in Section 11.5. No personnel will re-enter the exclusion zone until the cause of injury or illness is determined and re-entry is considered safe. In case of severe injury, the SHSO will implement procedures to minimize the possibility of further injury. If the need to transport the patient to the medical facility supersedes the need to decontaminate the patient, the medical facility will be notified that the patient has not been decontaminated before the patient arrives. Documentation requirements are outlined in Section 7 .2. 11,2 INJURY IN THE SUPPORT ZONE If an injury occurs in the support zone, the SHSO will be notified immediately. Appropriate first aid will be administered and, if necessary, the injured individual will be transported to the designated medical facility. If the injury does not affect the safety or performance of site personnel, operations will continue. I Documentation requirements are outlined in Section 7.2. 1L3 FIRE OR EXPLOSION In the event of a fire or explosion at the site, the Morrisville Fire Department will be contacted at (919) 469-2156 as soon as possible, and evacuation of the site will begin immediately. 11.4 PROTECTIVE EQUIPMENT FAILURE If any worker in the exclusion zone experiences a failure of protective equipment that affects his or her personal protection, the worker and all coworkers will immediately leave the exclusion zone. Re-entry to the exclusion zone will not be permitted until the protective equipment has been repaired or replaced and the cause of equipment failure has been determined and is no longer considered a threat. 39 • • 11.5 EMERGENCY INFORMATION TELEPHONE NUMBERS PRC will have a mobile telephone on site.

The PRC SITE team's responses to concerns follow. la. For sample point~ 2 and 3 (untreated and treated soil), Table 4-3 specifies 12 composite samples per run, while Table 4-1 specifies four 2.5-hour composite samples. The associated texi states that each of the 2.5-hour composites will consist of at least four grab samples. Please clarify the number of samples that will be collected, and explain the timing and procedures for collecting the subsamples. Response: Four composite samples will be collected per test run at sample locations 2 and 3. One composite sample will be collected from each sample location every 2 hours per 8-hour test run. A composite sample will consist of four grab samples with one grab sample collected every 30 minutes. Each grab sample will be contained within a compositing jar which will be covered with a Teflon®-lined lid and placed in a cooler in between collection of each grab sample. Originally, 12 composite samples were·to be collected per test run from each sample location (four samples every 2.5 hours for a total of 12 samples per sample location). lb. In Table 4-3 under sample location 2, there is an entry·labeled "sodium carbonate •reagent""with·zero samples.and one blank. What is meant by this entry? Response: One composite sample of.the sodium bicarbonate reagent will be collected during mixing of the contaminated soil.-with·-the reagent'." The·composite,sample will consist"of at least 4 grab samples and will be analyzed for PCDDs/PCDFs, SVOCs, VOCs, and metals. The QAPP will be revised to de_signate the sodium bicarbonate sample as sample location 11. The original entry was meant to refer to sampling of a "reagent blank" to assure that the reagent contains no contaminants of concern. le. Table 4-3 provides for matrix spike samples for PCP for contaminated soils, while the text explains that these samples are too concentrated for matrLx spiking. Consistency is needed. Response: Matrix spike samples will be collected for SVOCs analysis as outlined in Table 4- 3. The text of the QAPP will be revised for consistency. Id. Table 4-1 and Section 4.4.1 list six composite samples for sample location 1 for the TCLP procedure, while Table 4-3 lists only three samples and one field duplicate. How many samples are intended. Response: The collection of TCLP samples at sample location I has been canceled. TCLP samples (I per test run) will only be collected at sample location 3. • • le. Table 4-3 lists oil and grease (O&G) for sample location 1 while O&G is not listed for this stream in Table 4-1. Please clarify. Response: Analyses for oil and grease (O&G) will be conducted on samples collected from sample location I. Table 4-1 will be revised to correspond with Table 4-3. lf. Table 4-3 lists pH for sample location 2 while pH is not listed for this stream in Table 4- 1. Please clarify. Response: Samples will be collected for pH determination al sample location 2. Table 4-1 will be revised to indicate the collection of pH samples at sample location 2. lg. Table 4-1 lists moisture for san1ple location 2 for the purpose of converting data to a dry-weight basis to calculate the efficiency of the BCD process. This seems to be inconsistent with the discussion concerning equation 1-1, which calculates removal based on the total mass of contan1ii:tant. Please clarify. Response: The determination of moisture content will be used for the purpose of converting data to a dry-weight basis only. Table 4-1 of the QAPP will be revised to indicate the change in rationale for collection of moisture content at sample location 2. Since data from both locations 2 and 3 will be converted to a dry weight basis, the contaminant removal efficiency of the .BCD process will .be determined by contaminant·concemration as opposed to mass of contaminant. lh. • Table 4-3 lists metals, O&G, and bulk density for sample location 3 while these paran1eters·are not listed for this stream in Table 4-1. Please clarify. Is bulk density . needed to calculate the total.mass of treated soil? If so,.it should also be included for untreated soil (Sample Point No. 1)). ' · Response: The analysis of metals, O&G, and bulk density will be'conducted for samples collected at sample location 3. Also, bulk density will be determined for sojl at sample location I as indicated in Table 4-3. Table 4-1 of the QAPP will be revised for consistency. Bulk density is a non-critical parameter and will be used to determine soil property changes resulting from the L TTR/MTTR. Soil mass will be determined by weighing drums of soil entering the LTTR/MTTR units. li. Table 4-3 lists three time-integrated samples per test run for each of the gaseous streams while footnote "d" states one composite sample per run. Please clarify the number of samples per run for the gaseous streams in Table 4-3. Response: One time-integrated sample per test run will be collected for each gas stream sample location. Table 4-3 will be revised accordingly. lj. Table 4-3 lists metals analysis for sample location 6 while metals analysis is not listed for this stream in Table 4-1. Please clarify. Sodium hydroxide reagent is listed as a parameter for sample location 6 in Table 4-3 with zero samples and 1 blank to be taken. This entry is not understood. Please explain. 2 • • Response: Metals analysis will be conducted on samples collected from sample location 6 as indicated in Table 4-3. Table 4-1 will be revised to correspond with Table 4-3. ' Also, a separate sample of the sodium hydroxide reagent will be collected per test run of the LTR. The sample will be analyzed for PCDDs/PCDFs, SYOCs, VOCs, and metals. The QAPP will be revised to designate the sodium hydroxide reagent sample as sample location 12. lk. Sample locations 6 and 7 are described as solid samples in Table 4-3. These are oil samples, Please revise, Response: Sample locations 6 and 7 are the L TR influent and efflue_nt which consists primarily of LW I 10 oil from the LTTR/MTTR oil scrubber system. The QAPP will be revised to indicate sample locations 6 and 7 as being oil samples. 11, Table 4-3 lists particulate loading and moisture content for sample location 8 while these are omitted from Table 4-1; on the other hand, Table 4-1 lists O&G and pH for this sample point, both of which are inappropriate for gas san1ples, Please clarify, Response: Particulate loading and moisture content samples will be collected for analysis at sample location 8 as indicated in Table 4-3. Table 4-1 of the QAPP will be revised accordingly. Also, oil and grease (O&G) samples and pH samples will be removed from sample location 8 in Table 4-1. lm,. -Table 4-3 lists three time-integrated.samples per run for.sample.location 8. Footnote "d" .states that there is 1 composite. (integrated) sample ·per run. Please:clarify the number of .-samples per-run for sample-location 8 in Table 4-3, , ·Response: As stated in'Response Ii, onetime-integrated·sample·per test run will be collected from each gas stream location. Table 4-3 of the QAPP will be revised for consistency. ln. For sample location 9 in Table 4-3, seven samples are listed per test run. Footnote "r' states that there is 1 san1ple for each thermal desorber run and L TR run, Please correct the number of samples per run for sample location 9 in Table 4-3, Response: One time-integrated gas sample will be collected from the stack gas sample location (designated as sample location 5 in the revised QAPP) during six runs of the L TTR/MTTR and two runs of the L TR. Table 4-3 of the QAPP will be revised to indicate the changes. lo. Three samples per test run are listed for sample locations 10 and 11 while footnote "c" lists four composites for each five runs, Please clarify the number· of samples per run for these streams, Response: The condensate water will be stored in the condensate storage tank for use in the L TTR/MTTR water scrubber system during the course of the demonstration. The condensate water will be treated at the end of the demonstration, prior to demobilization. Three grab samples will be collected from the condensate storage tank (designated as sample location 9 in 3 • • the revised QAPP) prior to treatment. The treated condensate (wastewater) will be placed into a treated wastewater storage tank. Three grab samples (designated as sample location 10 in the revised QAPP) will be collected at the end of wastewater treatment. Tables 4-1 and 4- 3 in the QAPP will be revised to indicate the change in sample frequency. Also a sample of the scrubber water/cooling water supply source will be collected to assure that no contaminants of concern are detected with the water supply. lp. Preliminary samples will be analyzed on site with a portable gas chromatograph. Which samples will be used. for this purpose? Response: Preliminary samples will be analyzed on site for all sample locations (primarily for sample locations I and 3) except gas sample locations. Data will be used for process control only and is considered non-critical. · lq. For most analyses at sample point 1, three composite samples will be collected over the entire project. Section 3.3.1 explains the compositing procedure once subsantples have been collected. However, there is no explanation regarding how the initial subsamples will be collected. These should be tinted to be representative of the entire mass of soil that is treated. Response: The text describes collection of grab samples in paragraph 3 of Section 4.4.1. A determination of collection times. for grab samples will·be;estimated during manual screening of the soils based on the time necessary to screen approximately 0.5 ton. Screening of soils for the demonstration will be completed.prior to the start.of the.BCD process demonstration. The text of the QAPP .will be revised to ,indicate. the method for determining the grab sample. collection time interval. lr. .According.to page 4.0-3_, san1ples of treated soil will be,collected before it is cooled \\ith process water. This approach raises.two co~cerns. ;First,,this approach will overlook any addition of contaminants from the process cooling water. Second, volatiles would likely be lost during the sampling procedure. Is the description of this sampling point in the tex1 correct, or will the soils actually be sampled once they have cooled to room temperature, as is suggested in Figure 4-1? Response: Treated soils (sample location 3) will be collected after it is cooled with process water .. The text of the QAPP will be revised to indicate the point of collection for soils at sample location 3. The cooling water will consist of either tap water obtained from the local municipal water supply system, or treated condensate water from the BCD process. Samples of the cooling water will be collected to assure no contaminants of concern are detected in the cooling water supply source. ls. Approximately 10 percent of the samples in Table 4-3 are field duplicates. However, there is no indication of how such duplicates will be collected. Please provide procedures for collecting field duplicates. How will the data from such duplicates be treated? 4 • Response: Field duplicate samples will be generated by collecting twice the necessary volume for a designated sample. Double volume samples will be composited and quartered prior to containerization. The data for duplicate samples will be used to assess sample variability. The duplicate results will be averaged for the sampling event that was duplicated. The text of the QAPP will be revised to indicate the collection method and use of duplicate sample data. lt. Volatile organics will collected with methanol extraction procedure. Please note that this approach will result in poorer detection lin1its for the VOCs than are listed in Table 3-4. Please revise this table accordingly to be sure· that all parties are in agreement regarding this detem1ination. Also note that this procedure will require that the mass of soil and the volume of methanol be recorded to permit a calculation of the final concentrations in the soil. Response: Volatile organic samples will be collected as individual grab samples and analyzed by Method 8240. The methanol extraction method will not be used. The text of the QAPP will be revised to indicate the change in the volatile organic sample collection procedure. 2. How will the mass of treated and untreated soil be detemtined? lb.is information is needed to estimate treatment cost (objective 4) and for calculating removal efficiencies. Will the soil be weighed in some manner, or will soil mass be estimated from volume and bulk density measurements? It is unclear whether soil mass should be considered.as critical or-noncritical. Section 1.5 discusses calculation of the removal efficiency based on the total amount of contaminant rather than the contaminant concentration. These procedures will require that the mass of material used and recovered for each run be measured in a traceable manner. -However; the mass of feed material or product has not been designated as a critical paran1eter, and no QA objectives been set for mass.determinations. If the data for this·project will be analyzed according to equation 1-1, the mass detem1inatious will be critical and QA objectives must be set. Appropriate calibration and QC procedures will also have to specified. Please make appropriate revisions. Response: The soil mass is considered a critical measurement for determining treated cost. and will be determined by weighing feed soil entering the L TTR and MTTR. Drummed contaminated soils will be emptied into the L TTR/MTTR feed hopper. The drums will be weighed prior to and after emptying the contents: of the drums. The mass of treated soil will not be measured. As stated in Response lg, removal efficiency will now be determined by concentration. 3. Section 1.3 lists 5 objectives for this demonstration. There are two concerns related to these objectives. 3a. The second objective is to "Determine the ability of the process to produce effiuents (treated soil, oil, water, and gases) that meet applicable local, state, and federal standards for disposal or discharge." Later in this section (page 24), the measurements critical to this objective are listed as PCP, PCDDs, and PCDFs in gas, water, and oil, as well as particulate matter in the stack gas. However, the numerical values for the local, state, and federal standards are note presented. Without these values, the 5 • • appropriateness or the sampling and analysis procedures cannot be evaluated. Please supply the numerical values for these standards, if possible. I Response: The soil residual must be treated. For soil, PCP must be treated to less than 95 ppm and dioxins and furans must be treated to less than 7 ppb.The appropriate re~triction for disposal of residual wastewater and air are listed below. Federal Effluent Requirements (40 CFR Part 268) HXCDD -all Hexachloro-dibenzo-p-dioxins HXCDF -all Hexachloro-dibenzofurans PeCDD -all Pentachloro-dibenzo-p-dioxins PeCDF -all Pentachloro-dibenzofurans TCDD -all Tetrachloro-dil:ienzo-p-dioxins TCDF -all Tetrachloro-dibenzofurans 2,4,5-TricWorophenol 2,4,6-Trich!orophenol 2 ,3 ,4 ,6-Tetrachlorophenol Pentachlorophenol Phenol 2,4-Dichlorophenol 2,6-Dichlorophenol . · Hexachlorod ibenzo-p-dioxin Pentachlorodibenzofurans Pentachlorodibenzo-p-dioxin Oil and grease _Phenols pH < I ppb < I ppb < I ppb < i ppb < I ppb < I ppb < I ppb < 0.05 ppm < 0.05 ppm < 0.01 ppm ..::;_ 0.039 mg/1 ..::;_ 0.044 mg/1 ..::;_ 0.44 mg/I ..::;_ 0.000063 mg/1 ..::;_ 0.000063 mg/I ..::;_ 0.000063 mg/I 1.5 lb/1000 cubic feet·of wastewater 0.14 lb/1000 cubic feet·of wastewater 8.0 to 9.0 at all times State Air Emmission Requirements (NCAC Part 20) HXCDF Pentachlorophenol Phenol Tetrachlorodibenzo-p-dioxin Sodium dioxide Nitrogen dioxide Particulates 0. 0051 lb/yr 0.063 lb/day 0.0064 lb/hr 0.24 lb/hr 0.00020 lb/day 2.3 lbs/million BTU input 0.6 lb/million BTU input 1.83 lb/hr per 600 lb/hr process material 3b. The third objective is to "Evaluate potential effects or chemical and thermal reactions or the BCD process on PCP, dioxins, and furans, such as forming other hazardous compounds." The discussion on page 24 states that for the third objective "the critical parameters are PCP, PCDDS, and PCDFs in the contaminated feed soil, treated sludge, treated liquid effiuent, and gas exiting the stack.". The measurement or these paran1eters 6 • • • is critical to the first objective; their applicability to the third objective is unclear. If one objective of this project is actually to identify reaction products, one would expect to employ analytical methods that are oriented towards the identification of such products. Rather, this project simply employs EPA method 8270 for standard analyte list. To identify reaction products, one might concentrate on identifying likely products, such as cWorinated phenols or partially oxygenated forms of pentacWorophenol. Perhaps reaction products have been identified from laboratory studies, and these products could be searched for during the current project. Please clarify this objective, and indicate which methods are critical to its attainment. Perhaps this objective could be addressed more easily with .a small scale;laboratory study, Response: Objective 3 is considered a secondary objective of the demonstration. Page 24 of the QAPP will be revised. The primary reason for choosing Method 8270 was the large number of compounds .which can be analyzed, simultaneously. Many of these compounds may be degradation or breakdown products of the thermal decomposition of PCP. These compounds include many of the chlorinated phenols, non-chlorinated phenols, ethers, and phenyl ethers. Another important reason for choosing Method 8270 is in the qualitative, positive identification of target compounds. The ability to positively identify compounds is a major advantage of this method. Another advantage for the use of Method 8270 is that it is possible to identify ,compounds which are no( included: in the target, analyte list. .This is performed through .'tentatively.identified compounds (TlCs). The 20 TICs,with the highest peaks will be identified if_possible. The .mass spectrometer software .program includes a 50,000 chemical ,compound·librnry of mass spectra data. This library can be invoked to help in the identification and quantitation·of.non°identified chemical compounds found in samples. This may ,be· extremely helpful -when•.searching for PCP degradation products. 4. It is questionable whether the accuracy objective of 50-150 percent recovery can be achieved for pentacWorophenol (Tables 5-4 and 3-1) without preliminary effort. PCP is .notorious for poor recoveries. In fact, Table 6 in Method 8270 lists the range of recoveries for PCP as 14-176 percent. The addition of sodium carbonate may further stabilize the PCP in the soil matrix and decrease recoveries. It is suggested that adequate recoveries be demonstrated for PCP before this project is initiated. The addition of a strong mineral acid to .the soil may be necessary to release the PCP during extraction. Response: Tables 3-1 and 5-4 will be changed to indicate that the accuracy objective for PCP is 14-to 176-percent, as is specified in Table 6 of SW-846 Manual Method 8270. PRC agrees that the recovery of PCP can be very poor when PCP analysis is performed with standard EPA SW-846 Manual Method 8270. The poor recoveries of PCP may be compounded by the addition of sodium carbonate during sample treatment. To address the concern of low PCP recovery inherent in Method 8270, PRC will be collecting a sample during the dry-run week (August 16) which has been run through the THERM-O- DETOX treatment process, and will have had sodium carbonate added to it. This sample will 7 be submitted to Versar before the start of the demonstration activities. Four aliquots of this · sample will then be spiked with PCP at each of four levels --10, 100, 1,000, and 2,000 parts per million, and analyzed using Method 8270. Versar will then perform a statistical analysis of the matrix spike data including: mean percent recovery, standard deviation, and determining the 95 percent confidence interval for percent recovery. Versar will transfer this data to the PRC project manager before the de_monstration activities begin. The 95 percent confidence interval from this evaluation should.fall within the range of 14-to 176-percent. If the 95 percent confidence interval exceeds these ranges PRC will contact the EPA TPM to determine corrective action. Corrective actions which may be taken includes acidifying samples and analyzing the acidified sample extracts by Method 8270. This course of action may reduce the number of compounds which can be reported due to the possibility of acidic breakdown of some Method 8270 analytes. This action may also limit the T!Cs data derived from the sample analysis, for the same reason. Another corrective action may include analysis of samples with Method 8270 and a separate analysis of samples with EPA SW-846 Manual Methods 8040 or 8151. These are gas chromatographic methods specifically designed to determine phenols and chlorinated acids. The main advantage to the use of these methods is that they should provide better recoveries for PCP and other chlorinated phenols. Another advantage is that the quantification of PCP may be more accurate with these methods than with Method 8270. Disadvantages of the use of these.methods are that the;number.ofianalytes reported.is much -smaller than.with Method 8270, and·the identification of:specific compounds is not as exact as ,with-Method 8270. Method 8040 and 8151 require,second column confirmation, or mass . spectrometer confirmation using Method 8270, for-positive-identification of compounds. Corrective actions which will be used will be detem1ined by the EPA TPM and the PRC project manager. 8 • • 2.0 RESPONSE TO MINOR ISSUES RREL's QA Manager identified nine minor issues regarding the subject QAPP. The PRC SITE team's response follow. l. There are also some concerns regarding stack sampling procedures. la. The estimated stack diameter and flow rate of the stack gas is needed to select the proper sampling equipment. What are the approximate diameters and gas flow rates at the various stack sampling locations for this process? Response: Gas samples to be collected during the demonstration include L TTR/MTTR off- gas, stack gas, and BCD liquid reactor off-gas (designated as sample locations 4, 5, and 8 in the _revised QAPP). The LTTR/MTTR off-gas· will be collected after the gas stream has passed through the oil and water scrubbers and condenser, prior to carbon polishing . . Originally, a separate off-gas sample was to be collected for the L TTR and MTTR (designated as sample locations 4 and 5 in Draft QAPP; see Attachment A for revised sample location map). The stack gas sample will be collected after the carbon polishing unit, prior to release of the gas stream to the atmosphere. The BCD liquid reactor off-gas stream will be sampled as the gas exits the reactor. The off-gas·flow rates-of the LTTR/MTTR and the BCD liquid·reactor is estimated at 65 cubic· feet per minute (cfm) and 6 cfm;. respectively. -The diameters of the off-gas/stack gas pipes are estimated to range between 2 to 4 inches. Radian .will finalize specific sampling · procedures during the week of the dry-run. lb. It inmclear whether gas san1ples will be analyzed for PCDDs/PCDFs by Method 23 (HRGC/HRi\1S) or by. Method 8280 (HRGC/LRMS). ·Samples.will be collected by Method 23, and such samples are normally aiialyzed as well by Method 23. However, Table 5-3 specifies Method 8280, although Table 3-2 gives detection limits from Method 8290, the SW-846 equivalent to Method 23. Clarification is requested. The primary difference here is that Method 23, which is based on high resolution mass spectrometry, gives more definitive identification and frequently better detection limits. If Method 8280 is indeed intended for the air samples, the detection limits in Table 3-2 for PCDD/PCDFs in air should be adjusted accordingly. The QAPP should also explain what changes, if any, will be needed to analyze Method 23 samples by Method 8280. Will labelled surrogates be added to the resin bed_ prior to sample collection? In Section 4.4.4, page 19, the discussion of the Method 23 train states that separate trains will be run for PCB, PCDDs, PCDFs, and SVOCs. PCBs have not been previously identified as part of·this project. Three sampling trains have been discussed, one for PCDDs/PCDFs, a second for SVOCs including PCP, and a third for particulates. Please clarify this discussion. Also, there is a typographical error in the description of the resin in the same paragraph: "SAD" should be XAD-2. Response: Method 8290 will be used for PCDDs/PCDFs analyses. Table 5-3 of the QAPP will be changed for consistency with Table 3-2. 9 • Also, the listing of a PCB gaseous sample train, and the "SAD" designation for "XAD-2" in Section 4.4.4, page 19, are typographical errors. The text of the QAPP will be revised appropriately. le. The minimum sample volume listed for the VOST train (VOCs in gas) is 1.8 liters. Twenty liters (0.02 dscm) is the typical volume collected and is the volume used to calculate the detection limits given in Table 3--4. Please clarify. Response: Samples for VOC analyses will be collected using passivated Summa canisters. The VOST sample train will not be used to collect a sample for VOC analysis. The text of the QAPP will be revised to indicate the change in VOC sample collection methods. Attachment A list the standard operating procedures for the gas chromatography/mass spectrometry analysis of air toxics canister samples using Method T0--14. Id. Section 4.7.1 discusses guidelines concerning construction and geometry_of a "standard pi tot tube." Will a standard pilot tube be used for this project? A type "S" pi tot tube is usually used for Method 5 sampling unless small ducts or stacks are involved. Please clarify. Response: A standard pilot tube will be used for this project. The ducts are too small to a Type S pitot. Where possible, we will install 4-inch PVC tubing (with no glued joints) with ports.at•appropriate distances,to.comply with the 8 and 2·diameter rule of EPA Method I. Gas velocity .and temperature will be measured with a standard pitot and them10couple as ,described in.EPA Method IA and 2C. It may not be feasible to -install a 4-inch diameter ,sample line, in which case the-smallest possible:standard pitot will be used, although the EPA methods cited do not apply to ducts less than 4-inches in diameter. If this approach is found to be ineffective, alternate techniques, such as use of a hot wire anemometer or measurement of total.duct gas. volume over: time, -may be attempted. le. Will the thermal desorbers and the BCD liquid reactor be operated simultaneously? If so, how can the gas emission at sample point 9 be apportioned between the various sources? Response: The thermal desorbers and the BCD liquid reactor will not be operated simultaneously. The demonstration schedule presented in the QAPP will be revised to indicate the days of operation for the respective units. 2. Scheduled QC and calibration 2a. In s~..:tion 3, page 5 of 14, it is stated that untreated soil (before and after the addition of sodium bicarbonate) will not be spiked for PCP because the expected level of PCP is greater than 1000 mg/kg. If matrix spiking is not used, how will the accuracy of PCP in this matrix be determined? Accuracy must be dctern1ined for each critical parameter in each critical matrix. Please describe the procedure for determining the accuracy of PCP in the feed soil. The next sentence in the same paragraph states that precision of PCP in feed soil will be assessed by serial dilution. There is no explanation why this procedure is being used over the typical laboratory duplicate. Please explain. 10 • • Response: Matrix spike samples and field duplicates will be collected for sample locations 1 and 2. The text of the QAPP will be revised accordingly. 2b. Table 5-4 specifies a 5% frequency for MS/MSDs. This appears to contradict Table 4-3, which specifies a definite number of MS/MSDs, typically at a higher frequency than 5%. It is recommended that Table 5-4 be modified to be consistent with Table 4-3. Response: Table 5-4 of the QAPP will be modified to be consistent with Table 4-3. 2c. In Table 5-4 corrective action for MS/MSDs is to flag the data. It is recommended that, at a minimwn, the project manager be notified as soon as possible. Response: The text of the QAPP will be modified to indicate notification of the PRC and EPA project managers upon initiation of corrective actions for MS/MSDs. 2d. In Table 5-4 the acceptance criterion for initial calibration for dioxins is RSD < 30%. To what measurement does this apply? The method requires that the RSD of each standard injected in triplicate be < 15%. Is the intent of this entry to relax this criterion somewhat? Or does this criterion apply to the linearity of the calibration curve? Response: Table 5-4 will be changed to indicate that the acceptance criteria for initial .calibration for dioxins is .:'o.-15 percent, as is specified in EPA SW-846 Manual Method 8280: 2e. In Table 5-4 there is, no procedure listed to determine accuracy ·for total organic carbon analysis. , Section 3 mentions matrix spikes .. ·Please resolve this :inconsistency. Response: Total organic carbon analytical accuracy is assessed ·through the use of matrix spike san1ples. The matrix spike will be composed of potasium hydrogen phthalate. Acceptable matrix spike recovery control limits generated by Versar are 80-to 120-percent recovery. This matrix spike recovery acceptance criteria will be added to Table 5-4. 2f. According the Sections 9.1 and 9.2, accuracy for PCDDs/PCDFs will be determined by MS/MSDs. This is probably incorrect because later in these subsections and in other sections of the QAPP, other procedures are specified for accuracy and precision for PCDD/PCDF analyses. Please resolve these inconsistencies. Response: Sections 9-1 and 9-2 will be changed to indicate that accuracy for PCDDs/PCDFs will be_ evaluated through the use of laboratory control standards. The accuracy criteria is 40- to 120-percent recovery. Accuracy will also be estimated by determining internal standard recoveries for each congener class. 2g. Page 3.0-4 states that precision for particulate matter will be determined by analyzing duplicate aliquots of a field sample. A Method 5 sampling train is not appropriate for aliquoting procedures. Precision of a Method 5 train is not routinely determined. Please clarify. Response: Precision for particulate matter will not be determined experimentally during the demonstration. The reference to particulate matter in the first sentence on page 4 of Section 3 11 • • should be deleted. Note that footnote "f" to Table 3-1 (relating to particulate matter) says, ("Precision and accuracy are based on EPA collaborative test." The following sentences will be inserted on page 4 of Section 3 of the QAPP. · Precision and accuracy for measuremerits of particulate loading and moisture in gas streams are not readily measured experimentally in a demonstration test. Adherence to method protocols, which include performance-related activities such as sampling equipment calibration, isokinetic sampling, balance calibration, desiccating filters to a constant weight, etc. is the basis for achieving acceptable method accuracy and precision. 2h. Footnote "d" to Table 3-1 indicates that the laboratory for gaseous PCDD/PCDF.sample analyses has not been detennined. This is probably an oversight. Section 2 identifies three subcontract laboratories; which one will do these analyses? Response: Gaseous sample analyses for PCDDs/PCDFs will be performed by IT Corporation. The text of the QAPP will be changed accordingly. 3. Project organization. 3a. According to Figure 2-1, the QA manager is "to be assigned." This person should be identified in the revised. document to be sure that this .function is covered. Response: The IT QA.-Coordinator is Mary Tyler. The text of the QAPP will be revised accordingly. 3b. There is· some ambiguity regarding which laboratories will perform which analysis. Will Radian ·perfonn all analyses on all gas samples, including .. dioxins and furans? Will all · dioxin,and.furan determinations be performed by IT?,,Clarification is needed to assure that samples are sent to the correct laboratory. Response: All gas sample analysis will be performed by Radian, except those to be analyzed for PCDDs and PCDFs. IT Corporation will perform PCDD/PCDF analysis on all gas, soil, water, and oil samples. Versar will perform all listed analysis for soil, water, and oil, except for samples listed for PCDD/PCDF analysis. Table 3-1 of the QAPP will be revised to indicate the appropriate lab for each listed analysis. 3c. Figure 2-1 suggests that the QA managers actually report to the project man°agers and thus lack essential managerial independence. Please clarify. Response: Figure 2-1 of the QAPP will be modified to indicate managerial independence of the QA managers. 3d. Who is responsible for the physical measurements such as particle size distribution and bulk density? Who is responsible for field measurements such as PCP? Response: Versar is responsible for all physical measurements on soil samples including particle size distribution and bulk density. As stated in the 3b response, Table 3-1 of the 12 • • QAPP will be revised to indicate the appropriate lab for each listed analysis. PRC is responsible for all field measurements, such as PCP in soil and water. Radian will measure air flows and ETG will perform all p~ocess measurement. · 4. Please describe the sample numbering system that will be employed during this project. Entering this information in the QAPP helps the sampling team to properly id~ntify samples. Response: Samples will be labeled according to sample location numbers (SL#), test run number (TR#), and composite number (C#). For" example, the third composite sample collected during the fifth test run of the L TTR/MTTR at san1ple location 3 will be labeled SL3-TR5-C3. The text of the QAPP will be revised to indicate the san1ple numbering system. 5. Table 4-4 should be modified to provide for addition of sulfuric acid to pH < 2 as a preservative for water samples collected for oil and grease. Response: Table 4-4 of the QAPP will be revised to indicate the addition of sulfuric acid to pH < 2 for preservation of water san1ples collected for oil and grease analysis. 6. According to Figure 4-1, the BCD process employs activated carbon beds for cleaning water and gas before discharge. How will the lifetime of this units be estimated for the · purpose of calculating operating .costs? How• will;disposal costs for the these systems be estimated, considering that.they may·be badly:contaminated? Response: Capacity and cost for granular activated carbon (GAC) units are readily available · from manufacturers literature. •By .measuring inputs to both water and air GAC during the demonstration, ·an estimation.of operating and disposal costs will be determined. 7. There are a number of•issues-related to the analytical methods listed in Tables 5-1, 5-2, and 5-3. 7a. First, Table 5-1 should distinguish between aqueous samples and oil samples. The term liquid includes both oil and water although different preparation procedures are typically required. Modified Method 3020 is listed for the preparation of liquid samples for arsenic, lead, and selenium analyses. Methods 7060 and 7740 have preparation procedures for aqueous samples contained in them. V.'hy is a modified method being proposed? Method 3020 is acceptable for preparing aqueous samples for lead analysis. Why is a modified method being proposed? What preparation method will be used for oil samples? Response: Table 5-1 will be changed to indicate three types of matiices: (1) water; (2) solid, sludge, and oil; and (3) gas. Oil samples are treated differently than water samples, and the preparation techniques employed for oil samples are usually by solvent dilution for organics, and by solvent digestion for metals. Oils typically do not have the same density as water (LO gram per milliliter). For example, a degreasing oil may contain greater than 1,000,000 milligrams per liter of tetracholorethylene. To obtain more realistic and accurate data, oil samples will be reported on· a weight-to-weight basis. 13 • • Table 5-1 will be changed to indicate that water sample preparation methods for arsenic will be EPA SW-846 Manual Method 7060, and for selenium will be EPA SW-846 Manual Method 7740. The aqueous sample preparation method used for the analysis of lead will be EPA SW-846 Manual Method 3020. Oil samples will be prepared by EPA SW-846 Manual Method 3040 for metals analysis. 7b. Method 3520 is listed in Table 5-2 for preparing solid samples for SVOC analysis. Was Method 3550 intended? Response: The preparation methods used for soil and sludge sample preparation will include both EPA SW-846 Manual Methods 3540 and 3550. The analytical laboratory performing sample analysis will be given the option of choosing the preparation method, and will be responsible for verifying the methods applicability to sample matrices encountered during this demonstration. 7c. Modified Method 3050 is listed for arsenic, lead, and seleniwn. Footnote "d" indicates that the modification involves the addition of hydrogen peroxide. Method 3050 already includes the use of peroxide. Please explain. · Response: Table 5-2 will be changed to read Method 3050 and footnote "d" will be removed. 7d. Methods 413.2 and 9252 arc listed for preparing solid •san1ples in Table 5-2 for oil and . grease and chloride analyses. These methods are for water•samples. Please supply . appropriate methods for ·preparing solid san1ples. Response: The method used for the analysis of oil and grease in soil, sludge, and oil samples will follow the same procedures that are listed in·EPA SW-846 Manual Method 9071. This . method is·applicable to sludge samples,'and-Versar has indicated that,they follow the sample preparation and analysis procedures for soils, sludge, and oil. Table 5-2 will be changed to show that Method 9071 will be followed for soil, sludge, and oil analysis of oil and grease. The method used for the analysis of chloride in soil, sludge, and oil will involve the separation and transfer of chloride ions from the soil, sludge, and oil into water. Once the chloride ions have been exchanged to water the remainder of the analysis steps are identical to those listed in EPA SW-846 Manual Method 9252. PRC and Versar have not been able to identify a specific EPA-approved method performing soil, sludge, and oil sample analysis for chloride. The method which Versar will use will be referred to as Modified Method 9252. The standard operating procedure for Modified Method 9252 will be provided to EPA by Versar. Table 5-2 will be changed to indicate that Modified Method 9252 will be used for , preparation and analysis of chloride samples. 8. According to Table 1-9 (schedule) only one week is allowed for shakedown and process optimization. Will this be enough time for optimization, including completion and interpretation of analytical results? 14 • • Response: The schedule of activities to be presented in the revised QAPP is as follows: Week 6f August 9 Week of August 16 Week of August 23 Week of August 30 Week of September 6 Equipment mobilization and soil delineation, excavation, and preparation Dry run of BCD process equipment Three test runs using the LTTR/MTTR, one test run using the LTR, and the visitors day (tentative) Three test runs using the L TTR/MTTR, and one test run using the LTR Equipment demobilization 9. Data reduction and reporting. Who will store raw data and samples, and for how long? Providing a checklist of forms that will be required in the analytical report for each analysis will expedite the report preparation procedure. Will the investigators require data-.on magnetic media? , Response: Samples·will·be stored by the.respective analytical labs for at least 4 weeks after the submittalof data analysis reports .. -The data analysis reports will be·stored for no less than I year. 15 • • 3.0 CHANGES RECOMMENDED BY SITE TEA.i\1 MEMBERS The SITE team QA managers identified changes to the QAPP that are listed below. 3.1 CHANGES RECOMMENDED BY RADIAN CORPORATION la. After the first sentence in the second paragraph of Section 3.1, insert: For gas samples, duplicate media spiked samples (spiked blank sorbent resins), rather than matrix spiked samples, will be used for semivolatile and volatile organics. Matrix spikes of impinger solution aliquots will be used for metals and HCI in gas samples. I b. To the end of the last paragraph on page I of Section 3. I, add: Precision for PCDD/PCDF analysis in gas samples will be estimated as the relative standard deviation for recoveries of the pre-sampling surrogate spike in the replicate test runs. le. Change the first sentence of the last paragraph on page _4 of Section 3.1 to read: Accuracy for SVOCs, VOCs, metals, chloride, HCl/chlorine, and TOC will be estimated as percent recovery of the true analyte from matrix spike samples (media spike samples for SVOC and VOCs in gas.samples.) [Note: the change is shown in parenthesis.] Id. To the second paragraph on page five of Section 3.1, add: Accuracy for PCDD/PCOF in gas--samples will be estimated from pre-sampling surrogate spike recoveries. 2. Change precision objective for metals in gas samples listed in Table 3-1 to 20 RPO and recovery objective of 75-125%. Also, change precision for HCl/chlorine in gas samples to 20 RPO. 3. Change the precision objective for metals trains in Table 3-6 to 20 RPO. 4. Insert the following to replace Section 4.4.5. The LTTR/MTTR and LTR will be run separately; thus, the resulting stack gas from each of these two processes will be sampled separately. The reactor off-gases will be sampled at he carbon bed siack for PCODs/PCDFS, particulates, moisture, SVOCs, VOCS, and HCI/Cl2• These samples will be collected through ports installed in the carbon bed exit line. The exit line from the carbon bed will be modified to accept 4-inch PVC tubing. The tubing will then be routed to facilitate sampling. Ports will be installed at appropriate distances to comply with the 8 and 2 diameter rule of EPA Method l. Gas velocity and temperature will be measured with a standard pitot and thermocouple ·as specified in EPA Method IA. The gas samples will be collected by either standard U.S. EPA stack sampling methods as published in 40 CFR Part 60 (Standards for Performance for New Stationary Sources, Appendix A, 16 • • Reference Methods) or methods outlined in the, Methods Ma.nual for Compliance with the BIF Regulations. The sampling trains to be used during the tesrare briefly described below. Samples for SVOCs will be collected by a modified Method 5 (MM5) sampling train, Method 0010 in SW-846. Samples for PCDDs/PCDFs will be collected by M23. The MM5 and M23 train are shown schematically in Figure _. The sampling approach and requirements for both MM5 and M23 are identical. Differences exist in the preparation and recovery of the trains. Method 23 has more stringent requirements for preparing the filter and XAD resin than does Method 0010. • A heated, three-foot borosilicate glass-lined sampling probe will be insened into the duct to withdraw the sample. The probe will be equipped with a stainless steel (316) nozzle, sized to withdraw the sample isokinetically. • Gas will pass from the probe to a borosilicate filter holder contai.ning a 90 mm Reeves-Angel 934 A-H glass fiber filter (or equivalent). The filter assembly will be enclosed in a heated chamber capable of maintaining a temperature of 120 °C. • The filter will be followed by an impinger train consisting of a spiral-type, ice water-cooled condenser; an ice water-jacked sorbent module containing . approximately 20. grams of 30/60 mesh XAD-2 resin (pre-extracted); a temperature sensor; a I-liter con'densate trap; two standard Greenburg-Smith • , impingers; 'each containing approximately 100 mis of deionized water and a final modified Greenburg-Smith impinger containing silica gel plus a ·thermocouple to detect sample gas exit temperatures. The impinger train is contained within an ice bath. • A vacuum line will connect·the outlet of the impinger train to a control module.consisting of a vacuum pump, a calibrated dry gas meter, a calibrated orifice and an inclined manometer. For each test run, the following material will be recovered from the MM5 and the M23 sampling trains as described in Method 0010 and M23; rinsate from the sample probe and the front half of the filter holder, the filter, the XAD-2 resin sorbent module, liquids collected in the I-liter condensate trap, and rinsate from components between the back half of the filter holder and the condensate trap. M23 also includes a final toluene rinse. The recovered material will be extracted and analyzed for SVOCs, or dioxins and furans. Each sampling train will generate several samples, however, the extracts of each sample will be combined to produce one final sample per train. The BIF Method 0050 sampling train will be used to measure particulate HCI/CI, and moisture content of the gas stream. The BIF Method 0050 train is shown schematically on Figure_. This sampling· is similar to the MM5/M23 train described above, with the following exceptions: • , The water cooled condenser and sorbent module are removed. 17 • • • The impinger train will consist of five impingers. The first is empty. The second and third will contain 100 ml of 0.1 N sulfuric acid. The fourth impinger will contain 100 ml of 0.1 N sodium hydroxide. The last impinger will contain silica gel as a final ,water trap. Volatile organic compounds will be collected using passivated Summa canisters for analysis by GC-MS following the general guidelines of U.S. EPA Compendium Method TO-14. 5.

STANDARD OPERATING PROCEDURE FOR THE GAS CHROMATOGRAPHY/MASS SPECTROMETRY ANALYSIS OF AIR TOXICS CANISTER SAMPLES USING METHOD TO-14 1.0 PURPOSE This standard operating procedure provides a method for the analysis of canister air samples by gas chromatography, using the.method and analyte list from EPA Compendium Method TO-14 with a Finnigan 4500 GC/MS/DS in either multiple ion detection (MID) mode or the full scan mode in conjunction with the sample interface system built by Radian Corporation. This analytical method can be used to quantify many volatile organic compounds with boiling points less than 200'C. Analytical properties of polar compounds in canisters are not well defined currently. The GC/MS analysis of gas samples from·canisters.in restricted t~ use by, or under the supervision of, analysts experienced in the use of GC/MS systems, and•skilled.in the interpretation of mass spectra and their use as quantitative tools. 2.0 SCOPE AND APPLICABILITY This method may be applied to the analysis of air toxics samples which are introduced to the GC/MS using the Radian sample interface system with the method and analyte list from EPA Compendium Meihod TO-14. The method is applicable to ambient air, indoor air, to landfill gas, and to any air samples with volatile organic analytes present below hundreds of ppbv. The method is not applicable directly to samples from combustion processes. A modification of the method to allow direct gaseous injection may be performed to analyze air samples which contain high levels of organic compounds. 3.0 METHOD SUMMARY Field samples are received at the Radian laboratory in canisters. These samples are logged into the Radian Sample and Analysis Management (SAM) system and scheduled for analysis in the GC/MS laboratory. An analytical mode, either full scan for maximum nexibility or MID for maximum sensitivity, is selected and appropriate gaseous calibration standards are prepared. The instrument is tuned and the range of calibration standards is analyzed. A calibration curve is obtained by linear • • regression, with a goal of a correlation coefficient of 0.995 for each analyte. After the calibration samples have been analyzed, a zero air sample containing pre-purified humidified air is analyzed. Then, the samples are analyzed. Quantities of the analytes in the sample are calculated from the linear regression and reported through the SAM system. If qualitative/semi-quantitative analysis of non-target analytes is desired, enhanced mass spectra obtained in the full scan mode are searched against the 42,222-compound NIH/EPA reference library, and the data are interpreted by an experienced mass spectroscopist. Semi-quantitative calculations are performed by comparison of the signal level for a tentatively identified compound (TIC) to a compound in the sample with a concentration which is accurately known_. 4.0 INTERFERENCES This analytical method is based on the identification of mass spectra using the appearance of the spectra, comparison to reference spectra, and (for the target analytes) comparison to accurately known retention time. Any elements of the gas matrix which might interfere with the ability to ,identify the mass spectra, obtain accurate-peak areas,·or obtain.an accurate retention time which can be compared to a reference standard will affect the performance of the analysis. If intense .,interfering peaks.are encountered, the chromatography will be distorted. The only possible solution to the problem of.excessive compou·nd ·loading is dilution of the sample or analysis of a smaller volume. If a coeluting compound is encountered, the mass spectrum generally can be interpreted unless the coeluting compound is an.isomer of. the compound of interest and the masses·are the same or approximately the same. In this case, within the limits of the present method, the problem cannot be resolved. The analysis of blanks will demonstrate that the analytical system is free from interferences and a field blank can serve as a check on the occurrence on contamination in the sampling and handling procedures. The laboratory where volatile analysis occurs is completely free of solvents. 5.0 MATERIALS AND APPARATUS 5.1 Calibration Standards: supplied in a canister ready for use on the analytical system. Calibration standards are prepared in the Radian Volatile Organic Compound (VOC) laboratory. Standard canister numbers, analyte concentrations, source of supply, name of preparer, date prepared, and date received are supplied to the GC/MS laboratory with the standards. 2 • 5.2 5.3 5.4 5.4. l 5.4.2 5.4.3 5.4.4 5.4.5 • Radian Sample Interface System: designed and built by Radian to interface between ttie sample contained in the canister and the analytical system.

Glass Jet Separator. to accept a flow rate of approximately 15 mL/min from the mega bore column and 15 mL/min of makeup gas while allowing the mass spectrometer to operate at a vacuum of 10 .. torr or better. Data System: to allow for the continuous acquisition and storage on machine-readable media of mass spectra or MID data obtained throughout the duration of the chromatographic program, interfaced to the MS. The computer must have software that allows searching any GC/MS data file for ions of a specified mass and performing quantitative calculations against the linear regression generated by the calibration of the instrument. The software must allow integration of the ion abundances at a specified mass between a selected time or scan number limits.· The data system also must include the most 3 6.0 • • recent version of the EPA/NIH mass spectral reference library for identification of mass spectra. CHEMICALS AND REAGENTS Analytical standards are prepared in the VOC laboratory in canisters at the approximate dilution, so no chemicals outside the canisters are handled in the MS laboratory. 7.0 SAFETY Standard safety procedures for the mass spectrometry laboratory require that safety glasses with side shields be worn at all times. The use of equipment, the canisters, and the interface requires attention to electrical hazards, as well as sharp, hot surfaces. No analyst is allowed to operate the instrumentation without appropriate training and an SOP for the use of the Radian interface is available (Radian SOP 262-A T-00 I). 4 8.0 • PROCEDURE 8.1 Preparation of the Gas Chromatograph 8.2 8.1.l Install the chromatographic column: DB-624 megabore (0.53 mm) fused silica capillary column or equivalent, 30 min length. 8.1.2 8.1.3 8.1.4 8.1.5 8.1.6 Set the column-helium carrier gas flow to 15 mL/min.

Sensitivity is enhanced over the full scan mode, since no time is spent. monitoring masses which are not specifically of interest. However, only information specifically requested is obtained when the mass spectrometer_ is operated in the MID mode, so use of the MS as a universal detector is sacrificed for the additional sensitivity. 8.3.2.1 to 8.3.2.8. of Radian SOP 327-MS-038 detail the set up procedures for MID mode and should be followed as detailed there. 6 8.4 • • Initial Calibration 8.4.1 An initial calibration curve, either three-or five~point, must be prepared from canister standards provided by the VOC laboratory.

The actual files listed on the streamer tape are recorded in the tape logbook which is maintained for each instrument in the GC/MS laboratory. An archivial copy of a data package is r·etained for at least five years in the laboratory data archive. .. • • 9.3 Analysis Log Book Each analysis performed on each instrument in the GC/MS laboratory is logged into an analysis logbook for each instrument which contains the 'following information: file name, date, GC parameters, GC column, sample identifier, SAM number, method, and analyst. The specifics of the information to be recorded are listed in Section 10 of Radian SOP 327-MS-038. 10.0 QUALITY CONTROL I 0.1 Detection Limits Detection limits for air toxics canister analysis have been experimentally determined using the EPA method of seven replicates at 99% confidence level. The detection limits, determined according to Radian SOP 327-MS-027, are listed in Section 11 of Radian SOP 327-MS-038. Method precision, as.defined by the reproducibility of replicate.measurements has.been determined. Accuracy as determined by the analysis of. external audit ,samples. has been determined by the . accumulation of a historical database for ·audit samples . 10.2 . Method Quality Control Checks The quality control checks listed below are used to assure the production of data of known quality. 10.2.1 10.2.2 10.2.3 Calibration Criteria: A three-or five-point calibration is performed initially for the method and a linear regression is performed on the calibration data points. A correlation coefficient of 0.995 or better must be obtained for each of the target analytes. If the correlation coefficient is less than 0.995 for the analytes, additional calibration samples are analyzed until the criterion is met. Tuning Criteria: The instrument is tuned according to the manufacturer's criteri~ for perfluorotributylamine, with masses 13 I and 219 at 30% of mass 69, the base peak. If these criteria are not met, the instrument is tuned until the criteria are met. Analysis of Zero Air Samples: No target analytes should be observed in the zero air samples at levels above the method detection limits. If 11 • 10.2.4 • target analytes are observed, a new zero air sample is analyzed until a clean blank is obtained. Daily Calibration Check: A daily calibration check at the mid-point of the calibration range is performed prior to the initiation of any quantitative analysis. The amounts for the calibration check are generated in the data system by linear regression. Percent recoveries are calculated for the calibration curve. For the linear regression obtained from the original calibration data to be valid, the percent recoveries must be within 30 percent of the initial curve. 1( this criterion cannot be met, an additional daily calibration check sample is analyzed. If the criterion still is not met, a new multi-point calibration is generated. 12 •• I 1.0 DOCUMENTATION The analyst will report the following information .as specified in Section 11 of Radian SOP. 327- MS-038: canister information, program instructions, library and standards information, sample dilution, tuning data, calibration data, zero air sample data, sample data, calculation sheets, reference spectra, appropriate sections of the instrument logbook, and a tabulation of instrument conditions. The SAM work order number is used as the data file reference number if the sample is logged into SAM. All data are recorded on hardcopy from a computer or in black ink. Corrections should be made by crossing through the original entries with a_single line so the original entry is not obscured, and initialling the change. All instrument maintenance is documented in a maintenance log kept next to the instrument. Blank sample canister numbers are documented in the analysis log and on all chromatograms and analytical data. 13
