SEPA September 2024 United States Office of Chemical Safety and Environmental Protection Agency Pollution Prevention Risk Evaluation for Tris(2-chloroethyl) Phosphate (TCEP) Systematic Review Supplemental File: Data Quality Evaluation and Data Extraction Information for Environmental Release and Occupational Exposure CASRN: 115-96-8 September 2024 ------- This supplemental file contains information regarding the data extraction and quality evaluation results for data sources that were considered for the Risk Evaluation for Tris(2-chloroethyl) phosphate (TCEP) underwent systematic review. EPA conducted data extraction, and quality evaluation based on author-reported descriptions and results; additional analyses (e.g., statistical analyses) potentially conducted by EPA are not contained in this supplemental file. EPA used the TSCA systematic review process described in the Draft Systematic Review Protocol Supporting TSCA Risk Evaluations for Chemical Substances (also referred to as the '2021 Draft Systematic Review Protocol'). Data that met the RESO screening criteria during the full-text screening was extracted by three data types, general facility, occupational exposure, and environmental release, as explained in Section 6.2 of the 2021 Draft Systematic Review Protocol. Five different data quality evaluation forms were used depending on the data type and condition of use (COU), as explained in Appendix M of the 2021 Draft Systematic Review Protocol. All references with data points containing monitoring data (e.g., measured occupational exposures) underwent data quality evaluation as described in Section M.6.1, using the monitoring data quality metrics. All references with data points containing environmental release data (e.g., measured or calculated quantities of chemical release across facility fence line) underwent data quality evaluation as described in Section M.6.2, using the environmental release data quality metrics. All references with data points containing published models for environmental release or occupational exposure (e.g., published models used to calculate occupational exposure or environmental releases) underwent data quality evaluation as described in Section M.6.3, using the published models for environmental release or occupational exposure quality metrics. All references with data points containing completed exposure or risk assessments (e.g., completed exposure or risk assessments containing a broad range of data types) underwent data quality evaluation as described in Section M.6.4, using the completed exposure or risk assessments quality metrics. All references with data points containing reports for data or information other than exposure or release data (e.g., process description) underwent data quality evaluation as described in Section M.6.5, using the reports for data or information other than exposure or release data quality metrics. The extracted data and their data quality evaluation are available in the tables below. Additionally, each data type and condition of use is evaluated independently within a given study; therefore, each reference may have more than one overall quality determination (OQD) to reflect the quality of each outcome and the exposures and releases more appropriately as described by the study authors. No OQD is determined for each reference, as a whole, if it contains data from more than one evidence stream.

This ESD describes the following general categories and types of adhesives: nan It is therefore assumed that 62 percent of the 35 workers per site, or up to 22 workers per site, are potentially exposed to the chemical of interest while performing adhesive formulation process activities. No information was found that would provide bases for estimating the specific numbers of these 22 production workers that perform each of the exposure activities discussed in this section. Therefore, it can be conservatively estimated that all 22 workers per site are exposed during each activity.

Number of Production Workers Potentially Exposed to Adhesives during Motor and Non-Motor Vehicle, Vehicle Parts, and Tire Manufacturing (Except Retreading)A NIOSH Health Hazard Evaluation Report (NIOSH, 2006) included a study of a single automobile manufacturing facility. The study notes, at the investigated site, that approximately 120 workers per shift work in the body shop, approximately 120 workers per shift work in the paint shop, approximately 700 workers per shift work in the assembly area, and approximately 130 workers per shift work in skilled trades, such as maintenance workers and electricians. An additional 85 skilled-trade workers work during the midnight shift. It is not clear how many of these workers would be exposed to adhesives during manufacturing. Data from the FPA questionnaire indicates that the flexible packaging manufacturing industry utilizes the following PPE: chemical-resistant gloves and safety glasses. Heat-resistant gloves are used when applying hot-melt adhesives. Of the four sites that replied to the questionnaire, only one reported the use of respirators. This site applied solventless adhesives to substrates. In lieu of industry-wide survey data, this ESD assumes that the PPE reported by the questionnaires sites is representative of industry practices (FPA, 2009). potential for incineration, automated processes, and enclosed processes (see Control Technologies, pgs 61-62/189.

European Commission data (EC 2002) indicate that in 1999, EU imports of cars, light commercial vehicles and components were worth EUR 46.58 billion. During the same period, the EU exported the equivalent of EUR 61.35 billion. Thus there was a net trade surplus for the EU with the rest of the world amounting to EUR 14.8 billion in 1999. On this basis it could be argued that there is likely to be a net export from the EU of V6 in automotive goods. To be conservative, no attempt has been made to account for this trade in the assessment." (pg. 35/262)Imports of furniture into the EU were examined to identify whether additional V6 may be entering the EU via this route. Imports of upholstered furniture from outside the EU-15 amounted to 848 million Euros in 1997. Most of these were sourced from Poland (more than 50%). Imports have been increasing continuously since 1993 to satisfy a growing internal demand. Extra-European exports of upholstered furniture stood at 1.17 billion Euro in 1997, an increase of 25% on the previous year. Two countries accounted for more than half of these exports: the United States (39%) and Switzerland (15%) (UEA, 2002). Thus there was a net trade surplus for the EU with the rest of the world amounting to 322 million Euro in 1997. On this basis it could be argued that there is likely to be a net export from the EU of V6 in furniture products, especially as the main export market is the US and V6 is used to meet the US standard (California 117). To be conservative, no attempt has been made to account for this trade in the assessment." (pg. 36/263) "Moulded foam is mainly used in the automotive industry (seat cushions, headrests), with some use for office furniture. Slabstock foam is cut in accordance with the specifications demanded by customers, the main application being for furniture (EC, 1997). Slabstock foams are also used for rear car seats and fabric lining for seat covers and roofing in cars. The market for slabstock foams is around seven times larger than the market for moulded foams for car seats (Mark and Kamprath 2000)..,V6 is used in flexible slabstock polyether and moulded foams (Rhodia 2000)." pg. 31/262"Following manufacture, most (over 95%) of the V6 produced is used as a flame retardant in the production of flexible polyurethane (PUR) foam, mainly for use in the automotive industry. V6 is not used in rigid foams owing to cost considerations. Flexible foams are produced by pouring the blend of two raw materials (polyol and isocyanate) onto a rolling conveyer belt (slabstock foam) or into a mould (moulded foam). Moulded foam is mainly used in the automotive industry (seat cushions headrests), with some use for office furniture. The main application of slabstock foam is for furniture." (pg. 89/262)"Data provided by a foam producer indicates that V6 is used in the production of foams for use with textiles in the manufacture ofcar seat, door panels, soundproofing, head-liners and cushions. The bulk of the seats are made using foam that doesn't contain flame retardant. It is only the outer covering of foam associated with the covering fabric that contains V6. The assembly processes will vary depending on the product being made, but will usually involve the use of adhesives to laminate foam and the material being used for the interior of the car, cutting, trimming and stitching of components. Different operatives would carry out different tasks, so that, for example, one operator would laminate the foam and fabric, another would stitch and trim the seat covering and another would assemble the seat. Some of these activities may be carried out by employees in different companies." (pg. 107/262) "Flexible foams are produced by pouring the blend of the two raw materials (polyol containing additives including flame retardants such as V6, and di-isocyanate) onto a rolling conveyor belt (slabstock foam) or into a mould (moulded foam)...Blocks of PUR foam generally have to be cut into the required size/shape of the final product. This operation usually occurs after the blocks have cured and cooled. For some applications (e.g. seats for office furniture), PUR foam can be produced in a mould of the desired shape and so cutting is not required...Scrap foam may be sold as second quality foam, or will be granulated (to form 'crumb') and made into rebonded foam." pg. 31-32/262 "ISOPA data (undated) indicates that 400 foamers/moulders are involved in the production of furniture and bedding from PUR foam in Europe each year, consuming 530,000 tonnes of polyurethane. Given the price and specialist nature of V6, only a small number of foamers will use this flame retardant. Data have been provided by the producer of V6. The number of sites using V6 is known."

HERO ID: 10284991 Conditions of Use: Foam Recycling EXTRACTION Parameter Data Production, import, or use volume: "A survey carried out by EUROPUR (pers. comm. 7th December 2005) accounted for approximately 45 kilotonnes of rebonded foam produced in the EU, and it was estimated that approximately 60 kilotonnes are rebonded in total. A high proportion of this is produced in the UK (approximately 22 kilotonnes). Across the EU, only a low proportion of this willcontain flame retardants. Cheaper non-FR foam trim can be obtained exclusively but it is likely that a site rebonding FR-PUR will also be handling non-FR foam. It has been estimated that a typical site might rebond 3-5 kilotonnes of foam per year in total (pers. comm. 29th April 2004)." (pg. 33/262) "Use of Rebonded Foam - The relative high density and resilience of rebond make it suitable for applications including vibration sound dampening, sport mats, cushioning, packaging and carpet underlay and new applications are constantly being developed (ISOPA 2001a). In cars, rebond can be used for sound insulation, for example under the carpet in the boot. In cushioning, a strip of re-bonded foam is used along the front of some cushions on the basis that it is more hard wearing. There is also some use in office furniture (ISOPA 2003)." Pg. 33/262 "Rebonding - In a typical process, foam scrap is fed through a shredding machine and then into a granulator. The granules are screw conveyed into a vessel where the material is sprayed with pre-polymer and mixed to ensure a thorough coating. The coating granules are then screw conveyed into a rectangular or circular moulding press where the mix is compressed and consolidated as the pre-polymer cures. Curing is facilitated by steam injection (HMIP 1995). The condensate is ultimately removed under vacuum and vented to the air (pers. comm. 29th April 2004). The rebonded blocks are removed and allowed to stand in order to cool (HMIP, 1995). The foam product is then either cut (converted) in the usual way (EUROPUR, 2005a), or can be"peeled" from the block at the desired thickness and a suitable backing is then applied (EC, 2000). It has been reported that V6 is used as flame retardant for virgin and bonded flexible urethane foam (Ash 1997). While V6 will be present in off-cuts of slabstock foam which undergo rebonding, owing to cost considerations it is believed that V6 would not be added directly to the re-bonding process." (pg. 33/262)"Loose crumb - Shredded scrap foam is used directly for some applications. This is referred to as 'loose crumb' and is used in deep-buttoned soft-cushions for garden furniture and in some low-grade furniture applications. In Europe, the major use of loose crumb is reported to be in garden furniture. The foam industry has indicated that the market for reuse of scrap foam in this way is small and is deteriorating (Biirgi, 2002). To give a realistic worst case, and in the absence of firm information, it is assumed in this assessment that 70% of the scrap foam remaining in the EU will be rebonded and 30% will be recycled as loose crumb. While all such furniture previously was returned to the UK to meet the demand generated by UK regulations, 50% now stays in mainland Europe. For the purposes of this risk assessment it is assumed that 75% of scrap foam generated in the EU remains here, with the remaining 25% being exported to the US. Thus it is assumed that 75% of the V6 in scrap foam remains in the EU."

HERO ID: 10284991 Conditions of Use: Disposal EXTRACTION Parameter Data Process description: "The [plastic] ESD gives lifetimes for furniture of five to ten years. ISOPA (1997) gives PUR-specific lifetimes for furnishing/mattresses of greater than ten years. This is supported by reports that 50% of households change their upholstered furniture every eight to sixteen years (DTI undated). In the risk assessment, a lifetime of ten years is used. All in-service losses are evaluated on a regional basis (over 365 days per year) because no specific local source can be identified for these releases. All service is taken to be indoors." (pg. 44/262)"Disposal to landfill is considered likely to be the most significant route of disposal of flexible foam and other articles containing V6. Monitoring data for landfill leachate in England and Wales suggests that this is a significant exposure route for TCPP but not for TDCP. There are no monitoring data available on concentrations of V6 in landfill leachate. However, V6 has a lower volatility than both TDCP and TCPP and its water solubility and adsorption potential is intermediate between the two. It is therefore likely to be less mobile in landfills than TCPP. In addition, the tonnage of V6 in articles in service (and hence tonnages passing to landfill) per year, at the regional scale, is less than 5% of the equivalent tonnage of TCPP. Therefore the contribution of releases via landfill leachate to the PEC regional values is considered to be negligible for the present risk assessment."

The foam sheet is passed across a propane/air flame and the foam is then brought together with the textile material between pressure rolls. The flame treatment generates a chemically active surface which facilitates bonding to the textile substrate (HMIP, 1995). The high temperature used in flame bonding leads to emission of volatile organic compounds (VOCs), including benzene, together with hydrogen cyanide and particulate matter as a result of pyrolysis. Free di-isocyanates including toluene di-isocyanate (TDI), are also present in the fumes which are given off in the process, as a result of oxidation and chain scission (HMIP, 1995). Flame lamination companies within the EU have to comply with national emission regulations and most facilities achieve these requirements by the use of appropriate attenuation techniques. Activated carbon scrubbing techniques are often used to meet the more stringent national emission legislation (pers. comm. 22nd January 2007)."

Adhesives are generally composed of a binder material formulated with other components. Binders are typically natural or synthetic high molecular weight polymers. Binders may alternatively contain reactive organic compounds (e.g. prepolymers, oligomers, monomers) that form polymers during the bonding process. Some materials commonly used as binders in adhesive formulations are esters, natural and synthetic rubber, polyvinyl compounds, polyurethanes, epoxy resins, and acrylate polymers. Adhesives may also contain components such as non-reactive resins, plasticizers, fillers, thickeners, solvents, hardeners, and setting retarders (Ullmann, 1985).

Chemical repackaging - Generic scenario for estimating occupational exposures and environmental releases (revised draft). 11182966 Repackaging Parameter EXTRACTION Data Production, import, or use volume: Life cycle description: Process description: Throughput: Number of sites: Chemical concentration: Physical form: Table B-l presents PMN data on repackaging rate in kg chemical/site-yr. Repackaging Pre-manufacture notices (PMN) submitted from 2010 to 2020 under EPA's New Chemicals Program indicated imported and repackaged chemicals can be solids or liquids and may be neat or in solutions/mixtures and contained in various packaging types. After they arrive at the repackaging site, repackaging operations occur where the chemical is transferred from the transport container it was imported in to a new one of a different size in order to meet the customer's needs (JACO, 2021). Chemicals may also be transferred from original containers to intermediate storage containers before packaging into smaller containers (Cooke, 2013; NIOSH, 2009). Chemicals are expected to be received at repackaging sites in drums or larger bulk containers (supersacks, totes, tank trucks, etc.) (Cooke, 2013; NIOSH, 2009). The chemical of interest may be received in its final formulation and transferred directly from these large containers into smaller containers, charged to a temporary storage tank, or it may be charged to a mixing tank and diluted or mixed with other chemicals before it is repackaged. Once the chemical has been formulated to desired specifications, it can be repackaged. Workers may be potentially exposed during the unloading of chemicals from the original transport containers into temporary storage or new transport containers. Releases of chemicals may also occur during this stage, from open container surfaces (e.g., if the chemical is volatile), transfer operations (e.g., if the chemical is volatile or a powder), and original transport container disposal.Repackaging operations for liquid chemicals typically involve pouring or pumping the product from the original containers or mixing /storage tanks into the new containers. A study conducted by the Health and Safety Laboratory in the U.K. investigated two chemical repackaging sites (Cooke, 2013). At both of these sites the chemical was delivered to the site by road tanker and pumped into dedicated storage tanks. One of the sites, a hydrazine supplier, pumped the hydrazine into a mixing vessel where it was diluted with water and packaged into smaller containers for sale to customers. At the other site, trichloroethylene was pumped from storage tanks into a closed loop system where workers using a hydraulic lance connected to a semi-automated filling system transferred the chemical into new containers (Cooke, 2013). The usual process for repackaging solid chemicals differs from the processes for liquids. A NIOSH Health Hazard Evaluation Report (HHE) from 2009 investigated a repackaging facility that was transferring bulk shipments of silane-coated glass beads ranging between 0.2 - 1.2mm in diameter. At this facility, 2,200 lb supersacks of the product are lifted with a forklift over a metal bin, then cutting the bottom of the container with a knife to empty the beads into the bin. The metal bin is then lifted by a forklift, and the glass beads are poured into hoppers. From the hoppers the beads are gravity fed into smaller cardboard boxes or paper sacks that are shipped to customers (NIOSH, 2009). Workers may be potentially exposed during the transfer of chemicals from temporary storage into new transport containers. Releases of chemicals may also occur during this stage from open container surfaces (e.g., if the chemical is volatile), transfer operations (e.g., if the chemical is volatile or a powder), and cleaning any equipment that was used in during the process. The number of operating days is given in a range of 174-260 days/yr with an EPA default of 260 days/yr. Table 1-2 presents the number of repackaging sites based on 2019 U.S. Census data. A fraction of completed IRERs from 2010-2020 were reviewed, 21 submissions contained information on chemical repackaging. In these submissions, chemicals were repackaged at concentrations ranging from 1% to 100%, with a 50th percentile of 93%, a 95th percentile of 100%, and a mode of 100%. Solid or liquid.

Additives in plastics processing (converting into finished products) -generic scenario for estimating occupational exposures and envi- ronmental releases. Draft. 6549571 Additives in Plastics Processing (Converting into Finished Products) Parameter EXTRACTION Data Production, import, or use volume: Life cycle description: Process description: Throughput: Number of sites: Chemical concentration: Table 2 presents the types of thermoplastic resins, common uses, and 2003 production volume. The plastic manufacturing industry can be divided into four sections: polymer manufacturing, compounding, converting, and "in-house" manufacturing. This generic scenario will address converting operations. Polymer manufacturing will not be included in this scenario. Compounders produce masterbatches of plastic resins with specific properties by blending the polymer (resin), additives, fillers, and reinforcements. Converters receive the masterbatch of plastic resin from compounders and form finished plastic products. Compounding and converting may take place as the same facility ("in-house" manufacturing) or at separate facilities. This scenario assumes that compounding and converting take place at separate facilities; therefore, in-house manufacturing is not covered in this scenario. Various plastic processing operation descriptions are provided in Table 5, and a Process Diagram is provided on PDF pg. 10. More generally, polymer resin is received at the compounding sites from the resin manufacturer in the form of pellets. A compounding site blends the resin and additives to produce a masterbatch. The converting site then processes the masterbatch by shaping the plastic into the desired form for the final plastic product. The blending and forming may take place at the same facility ("in house" manufacturing) or separate facilities. As a conservative estimate, it is assumed that the compounding of the plastic resin and the converting of the resin into plastic products take place at separate facilities. Therefore, in-house manufacturing is not covered in this scenario. After shaping, finishing operations such as filing, grinding, sanding, polishing, painting, bonding, coating, engraving etc. are performed to complete the finished plastic product. This scenario covers the converting of plastic resins into finished products. Daily use rate = amount of resin / # converting sites / days of operation x fraction of additive x fraction of chemical in additive Overall, there were 12,191 Plastic Product Manufacturing establishments in 2001. Table 1 provides Number of Establishments for subcategories of NAICS 3261 Plastic Product Manufacturing. Default values used to represent the weight fraction of various additives in plastic resin range from 0.001 - 0.5. These values are provided in Table 2 and Table 3.

Tetrakis(2-chloroethyl) dichloroisopentyl diphosphate (V6) is an additive flame retardant produced from pentaerythritol, phosphorus trichoride, chlorine and ethylene oxide, and finds application mainly in the production of flexible PUFs for use in the automotive and furniture industry. Its application as additive FR in these products makes it subject to volatization or leaching from the polymer matrix. It exists in the same market domain with TCPP and TDCPP and is often used in cases where specific standards need to be met by enhanced flame retardant properties. Commercial V6 mixture (Antiblaze V6) has 4.5-10% TCEP as its main impurity by weight" pgs. 24-25/39 "Tris(l-chloro-2-propyl) phosphate (TCEP) is a non-volatile, colourless to pale yellow liquid, manufactured via the reaction of phosphorus oxychloride with ethylene oxide. On thermal decomposition, it forms carbon monoxide, hydrogen chloride, 2-chloroethane and dichloroethane."

"Although additives can be added to the monomer prior to polymerization, they are usually introduced immediately after polymerization, blended, and extruded to form granular(pelletized) products and compounds. Many additives are not introduced until the granules are processed into moldings, films, orfibers" (p. 2)."More than 90% of the flame retardants used in thermoplastics are of the additive type. They are added before, during, or after polymerization, but usually when the polymers are processedinto compounds or finished products. In the latter case, the retardant is often used as a highly concentrated masterbatch containing 50-80% of the agent" (p. 40).

These areas were chosen because they contain articles (such as computers, flat screen monitors, and/or building materials) that are known, or suspected, to contain TCEP.

(p. 3-15)Exposure to reactive flame retardants could occur at all points in the life cycle, including manufacture, use, and disposal (p. 3-2)." "See 3.1 on p. 3-1 - 3-2""Flexible foam is made either in large slabs ("slabstock") that are cut to shape, or in molds that have the shape of the finished product. The basic ingredients include polyols, isocyanates, blowing agents, and other additives (including flame retardants). In manufacturing slabstock, the ingredients are blended in a mixing head and deposited on a conveyor belt, where the polymerization reactions occur, and the foam is expanded by blowing agents into a large (e.g., 60 foot) "bun." The buns are cured before being cut into shapes for a finished product. In molded foam, the polymerization reactions occur within the mold, and are heated to accelerate curing.Furniture and other foam product manufacturers typically receive cured foam and do not directly handle flame retardant chemicals. Because slabstock is made in very large buns, uses requiring smaller pieces of foam may consist of off-cuts from larger buns. This may be why smaller polyurethane foam products may contain flame retardants, even when they are not required to do so by regulation.""""Flame retardants used in FPUF are typically classified as "additive." Additive flame retardants are blended evenly into the foam, but remain unbound."""

Akzo's Fyrol CEF contains 10.8% phosphorus and 36.7% chlorine, and is made from a three-to-one mole ratio of ethylene oxide (qv) and phosphorus oxychloride ((69)). This phosphate is used in rigid polyurethane and polyisocyanurate foams, carpet backing, flamelaminated and rebonded flexible foam, flame-retardant coatings, most classes of thermosets, adhesives (qv), cast acrylic sheet, and wood-resin composites such as particle board. It is used with melamine in flexible urethane foam cushions and institutional mattresses.
