1. Introduction/Purpose This document has been prepared for the American Coal Ash Association (ACAA), whose mission is to advance the management and use of coal combustion products (CCPs) in ways that are environmentally responsible, technically sound, commercially competitive, and supportive of a sustainable global community. ACAA is a nonprofit trade association devoted to the beneficial use of materials created when coal is burned to generate electricity. While ACAA is not a producer of CCPs, its members include CCP generators, marketers, and associated industries. Recent updates to the United States (U.S.) Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS) Code of Federal Regulation (CFR) Part 29, Section 1910.1200, 2012 (HCS, 2012) have brought the U.S. OSHA HCS into alignment with the United Nations (UN) Globally Harmonized System of Classification and Labelling System (GHS) - Revision 3; the update provides a common and coherent approach to classifying chemicals and communicating hazard information via Safety Data Sheets (SDSs) and labels distributed not only across North America, but globally (OSHA, 2012b; UNECE,2009). The revised standard was established to improve the quality and consistency of hazard information in the workplace, making it safer for workers by providing easily understandable information on the appropriate handling and safe use of chemicals. SDSs in the U.S. must follow the requirements set forth in OSHA HCS 2012. This document represents an update to the American Coal Ash Association Coal Combustion Product (CCP) Safety Data Sheet Guidance Document, dated September 2015. Its primary purpose is to assist ACAA member companies in developing SDSs for their CCPs. The update was required to incorporate new information on CCP composition, as well as updates to requirements associated with Crystalline Silica and Beryllium promulgated since 2015. During the development of the document, other regulatory updates/guidance that may affect the development of CCP SDSs were also incorporated. For purposes of this guidance document, CCPs include fly ash, bottom ash, circulating fluidized bed (CFB) fly ash, and CFB bed ash. This guidance document, and its associated appendices can serve as a guide for ACAA member companies in the development of U.S. OSHA compliant SDSs that accurately reflect the hazards associated with CCPs. It represents the information available at the time of development. As the guidance and associated appendices were based on composition data compiled in Appendix C (Composition Summary Data), only CCPs whose composition are limited to the substances identified at or below the levels specified are covered. Under the updated OSHA HCS 2012, it is the responsibility of the producer/distributor of a substance or mixture to provide a SDS if that product is considered hazardous per OSHA HCS 2012. OSHA HCS 2012 specifies that the chemical/product manufacturer is responsible for the development of the SDS (in this case, the CCP generator); however, it is also the responsibility of each workplace to ensure the safety of its workers and downstream users where their products are distributed. Therefore, it is in the best interest of the ACAA members—including generators, marketers, handlers, repackagers and distributors—to accurately and consistently assess the potential hazards associated with CCPs so that individual SDSs developed by each member company reflect the potential hazards of the CCPs during normal shipping and handling from initial development through the supply chain.

The SDS template, provided as Appendix B, has been developed per OSHA HCS 2012 specifications using the OSHA recognized American National Standards Institute (ANSI) Standard Z400.1: American National Standard for Hazardous Workplace Chemicals – Hazard Evaluation and Safety Data Sheet and Precautionary Labeling Preparation, as a guide. Publicly available information as well as data received directly from ACAA member companies were used to support the development of this document. Information on the different types of CCPs noted above were evaluated not only to confirm composition similarities, but to identify variations that could result in additional hazards associated with those variations. This report has been organized to assist the reader by providing a natural flow of information. The primary sections include: Introduction – This section provides an overview of the goals of the document.

Introduction to GHS/OSHA HCS 2012 – This section provides information on how hazards are evaluated and communicated under OSHA HCS 2012.

Coal Combustion Products – This section is a general information overview of the CCPs.

CCP Composition – This section provides a more detailed view on the composition of the various CCPs and how they are defined in both the U.S. and Europe.

GHS Classification – This section provides available test data on CCPs in support of the hazard classification. The hazard classifications of individual CCP components that may impact the overall CCP hazard classifications are also included.

SDS Development – This section provides guidance on the development of an SDS for CCPs.

2. Introduction to GHS/OSHA HCS 2012 With the adoption of HCS 2012, there was a major shift in the determination of the hazards of substances and mixtures. Previously, OSHA had specifically defined the substances determined to be hazardous to workers through a listing in 29 CFR 1910, Subpart Z. Under HCS 2012, it is still the responsibility of the chemical manufacturer/importer to assess the hazards of products distributed in the marketplace and communicate those hazards through the use of SDSs. HCS 2012 implements UN GHS Guideline, Revision 3 as the basis for this classification/hazard determination process. HCS 2012 also prescribes specific labeling, pictograms, and SDS format. The GHS Guideline requires an evaluation of physical/chemical, human health, and environmental hazards of products. This can be done by product testing, read-across to data from similar products or using a calculation process provided in the UN GHS Guideline for taking into consideration the individual components of the product. The GHS Classification system has been implemented, or is in the process of being implemented, in over 72 countries throughout the world. One of the earliest regions to adopt the GHS system was the European Union (EU). The EU instituted the system with the Classification Labelling and Packaging Regulation (EC/1272/2008). This regulation—in concert with the EU Registration, Evaluation and Authorisation (REACH) Regulation (EC/1907/2006)—led to the review of available information and the development of new information on the physical/chemical, human health and environmental characteristics of substances and mixtures. The data developed for REACH registration purposes is publicly available from the European Chemicals Agency (ECHA) and was used to assist in the classification of the CCPs evaluated and summarized in this guidance document. Conversely, Canada is one of the most recent to implement GHS. The promulgation of the Canadian Workplace Hazardous Materials Information System, 2015 (WHMIS, 2015) translates GHS, revision 5. The initial transition phase for SDSs distributed in Canada is currently underway. In this initial phase, all manufacturers and importers of hazardous materials must have a compliant SDS by May 31, 2018.

3. Coal Combustion Products 3.1 FLY ASH Fly ash is a fine, powdery, inorganic material resulting from the process of combustion of powdered coal that is carried by the flue gases. It may contain a small proportion of carbon particles resulting from the incomplete combustion of the parent fuel. Electrostatic precipitators or fabric filters remove the dust-like particles from the flue gasses of furnaces fueled by pulverized coal with or without co-combustion procedures. The combustion occurs at temperatures between 1300 – 1500 °Celsius (C). Typically about 60-80% of the ash is entrained in the flue gas and is termed fly ash. Fly ash particles are predominantly spherical in shape, and may include a small percentage of thin-walled hollow particles called cenospheres. The predominant elements in fly ash are Silicon, Aluminum, Iron and in some cases Calcium, which vary depending on the composition of its parent coal. Smaller amounts of Sulfur, Sodium, Potassium, Magnesium, Phosphorus, and Titanium are typically present as well (typically adding to less than 10%). Although the chemical composition of fly ash is typically reported as Oxides (e.g., Silicon as SiO2), most of its chemical constituents are bound in an aluminolisilate glassy phase, while others, to a lesser degree, form crystalline phases such as Quartz and Mullite, among others. The particles typically range in size from 1 to 100 microns in diameter, with median particle diameter of 20 to 25 microns. Fly ash is normally light gray or tan to dark gray in color and without odor. Fly ash has been further defined as: The finely divided residue that results from the combustion of ground or powdered coal that is

transported by flue gasses (ASTM Standard C125-18; ASTM International, 2018).

Discussion: This definition of fly ash does not include, among other things, the residue resulting from: (1) ) fluidized bed combustion; (2) the burning of municipal solid waste or any other refuse with coal; or (3) the burning of industrial or municipal solid waste in incinerators.

A fine powder mainly of spherical glassy particles, derived from the burning of pulverized coal, with or without co-combustion materials, which has pozzolanic properties and consists primarily of silicon dioxide (SiO2) and aluminum oxide (Al2O3) (Caddas-Vieira F. et al, 2013; EN-450 Standard).

3.2 BOTTOM ASH Bottom ash is agglomerated ash particles, created in a combustion furnace of a coal-fired power station, that are too large/heavy to be carried in the flue gases, and therefore fall through open grates to an ash hopper at the bottom of the furnace. It is a semi-vitrified granular material with a size similar to sand or gravelly sand ranging in color from tan or light gray to dark grey with virtually no odor. Its composition is similar to that of fly ash as both originate from the same parent coal. Because bottom ash is collected at the bottom of the furnace, it cools down at a slower rate than fly ash allowing for a higher degree of crystalline phases to form, and consequently, slightly lower amounts of aluminosilicate glass. Sulfate levels are generally lower than those of fly ash. Bottom ash is generally extracted by a hydraulic process

from the base of the furnace. Typically about 10 to 20% of the residue from the burning of pulverized coal is recovered as bottom ash. In the United Kingdom, bottom ash is also known as Furnace Bottom Ash (FBA). 3.3 CFB ASH (FLUE AND BED) CCPs are also generated from Circulating Fluidized Bed Combustion (CFBC) facilities. In a CFBC boiler, fuel particles are suspended in a hot, bubbling fluidized bed of ash and other particulate materials (sand, limestone, etc.) through which jets of air are blown to provide the oxygen required for combustion. Ash generated from this process is termed CFB Fly Ash or CFB Bed Ash. CFB ash is similar to pulverized coal ash products with the exception that it will generally have higher levels of non-glassy aluminosilicates (mullite), calcium sulfate (anhydrite gypsum) and calcium oxide (due to the use of limestone in the CFB process which reacts with SOx emissions to produce anhydrite gypsum). 3.4 SYNTHETIC GYPSUM Synthetic gypsum, also called flue-gas-desulfurization (FGD) gypsum is produced through a chemical reaction in the scrubbers that remove sulfur from the flue gases of coal-fired power plants. The scrubbers remove sulfur dioxide (SO2) from power plant emissions by passing the flue gases through a slurry of limestone (calcium carbonate: CaCO3). The sulfur dioxide in the flue gases reacts with the calcium carbonate to produce calcium sulfite (CaSO3); calcium sulfite is then converted into gypsum (CaSO4 · 2H2O) by oxidizing it with air. Gypsum has a Chemical Abstract Services Number (CAS #) of 7778-18-9 with a chemical identity under Toxic Substances Control Act (TSCA) of sulfuric acid, calcium salt (1:1). Approximately half of all gypsum beneficially reused in the United States is FGD gypsum. Due to compositional differences between FGD gypsum and other CCPs such as fly ash and bottom ash, synthetic gypsum is not evaluated in this guidance document. A guidance document specific to the evaluation of synthetic gypsum is also available from the ACAA.

4. CCP Composition 4.1 COMPOSITION EVALUATION DETERMINATION Two distinct types of processes that generate CCPs were evaluated: (1) pulverized coal combustion and (2) fluidized bed combustion. Regardless of the process, the components of the different ashes are similar while the component percentages may vary. The CCPs included in the scope of this Guidance are: Ashes (residues) as well as the following alternate names for Ash(es); Ashes; Ash; Ash residues;

Ashes, residues, bottom; Bottom ash; Bottom ash residues; Waste solids, ashes are identified by the CAS number 68131-74-8 by the U.S. Environmental Protection Agency (EPA) on the TSCA Inventory and by the ECHA with the European Classification (EC) number of 931-322-8;

– The European Union and the TSCA Inventory acknowledge these CCPs as a singular substance of Unknown or Variable Composition/Biological (UVCB).

– The TSCA inventory further defines the ashes as: “A residuum from the burning of a combination of carbonaceous materials. The following elements may be present as oxides: aluminum, calcium, iron, magnesium, nickel, phosphorus, potassium, silicon, sulfur, titanium, and vanadium.”

Note: These metals and metal oxides are generally present as inclusions in the aluminosilicate matrix.

– The definition applied by the ECHA to EC # 931-322-8 is the same found on the U.S. TSCA Inventory.1

Fluidized Bed Combustion (FBC) Ash is categorized by the ECHA using the same CAS # (68131-74-8); however, it is assigned a distinct EC number (931-257-5). The name associated with the EC number is Fluidized Bed Combustion Ash (residues of coal combustion in fluidized bed combustion boilers).

Both of these ashes are recognized by U.S. and EU regulatory agencies as UVCB substances with a CAS# of 68131-74-8. It is important to note that due to the variable composition of the ashes, the GHS classification (and subsequent SDS requirements) of each type of ash (i.e., fly ash, bottom ash and fluidized combustion bed ash) as well as ashes formed by the same process but arising from different coal sources may vary. In order to assess the appropriate hazard classification, a compositional analysis of each ash must be performed. For purposes of this project and requirements set forth in HCS 2012, fly ash, bottom ash, CFB fly ash, and CFB bed ash are defined as a singular UVCB substance with a CAS # of 68131-74-8. Compositional variants that may result in different/unique hazard classifications have been explored using data originating from ACAA member companies (SDSs and ASTM Standard C618 test reports), the Electric

1 The TSCA inventory represents substances present in U.S. Commerce. It does not identify nor delineate substances based on hazard. If a substance is not on the TSCA Inventory, it may not be placed into commerce in the U.S. without EPA approval. Hydrates are considered to be listed if their parent compound is listed.

Power Research Institute (EPRI), the United Kingdom Quality Ash Association, the European Chemicals Agency, as well as CCP compositional data found in peer reviewed published literature. Note: Two additional CAS#s were also identified and considered for applicability prior to the assignment of CAS# 68131-74-8. They are: (1) CAS# 69012-84-6 which appears to have been merged with CAS# 68131-74-8 and (2) CAS# 71243-67-9 which is associated with pozzolans, coal ash on the TSCA Inventory. The TSCA Inventory further defines it as a “pulverulent substance derived from by-product coal ash which reacts with slaked lime in the presence of water to form a cementitious compound. The following elements may be present as oxides: aluminum, calcium, iron, magnesium, potassium, silicon, sodium, sulfur, and titanium.” In addition, potential impurities that may be present in the ash were evaluated for their ability to require disclosure on the SDS and for impacts they may have on the hazard classification of the finished product. These impurities may be trace elements present from the coal itself or pollution control additives. Trace Elements: The trace elements with potential human health and/or environmental

concerns including arsenic, beryllium, boron, cadmium, chromium, cobalt, lead, mercury, manganese, and nickel may be present in the CCPs.2 Based on an analysis of the elemental composition of coal fly ash and bottom ash using the 90th percentile concentrations, these identified trace elements were found to be present at less than 1000 mg/kg or 0.1% (EPRI, 2010). As such, these trace elements would be below the threshold level for SDS disclosure and will not have an impact on the final CCP hazard classification. These trace elements were not further considered in the determination of individual CCP classifications in this document as they do not meet threshold levels requiring disclosure/consideration in the SDS development. It is important it note however, that if an individual member has data indicating that any of these trace elements may exceed 0.1% in their CCP, SDS disclosure of the component as well as the hazard classification of the component and overall CCP would need to be re-evaluated.

Additives: Based on identified level of common industry additives, most would not meet the reporting threshold for disclosure on the SDS at typical use levels and they would therefore not alter the overall classification of the CCP. Further information on the impact of these additives is addressed in Section 5, Hazard Classification.

Table 1 provides information on the substances and concentrations present in typical CCP compositions at ≥0.01% and evaluated for this SDS Guidance. The substances listed in Table 1 do not represent a single CCP formulation nor should they be used to represent an individual ACAA member CCP composition. The substance list is not meant to be exhaustive, nor does it restrict the levels of these substances in CCPs to the identified levels. If the composition of a CCP varies in either composition or level of an individual component, the CCP hazard classifications assigned in Section 5.4 Table 7 may not apply.

2 OSHA has recently promulgated a rule regarding occupational exposures to beryllium. See section 5.5.3 for additional information related to Beryllium and regulatory obligations related to its presence in the workplace.

Notes: 1 If the composition of a CCP varies from the above table in either composition or percentage, the CCP classifications assigned in Section 5.4 Table 7 may not apply. 2 Represents a combination of amorphous silica and aluminum oxide. Aluminosilicates may be in the form of mullite (CAS#1302-93-8); pozzolans, coal ash (CAS#71243-67-9); or aluminosilicates (CAS# 1327-36-2). The form is dependent on the source of the coal and/ or the process used to create the CCP. Pulverized coal combustion would be more likely to create high levels of pozzolans, coal ash (particularly bottom ash) due to the high heat of combustion while the CFB process would be less likely to generate this glassy aluminosilicate. 3 For purposes of this evaluation the various forms of crystalline silica were considered the same substance. 4 Includes iron oxide. 5 For purposes of this exercise, calcium sulfate, calcium sulfate dihydrate and calcium sulfate (gypsum) were considered the same substance. 6 Although the maximum level of calcium oxide in the reviewed CCPs was ≤41%, some CCPs may have calcium oxide levels up to 60%. Calcium oxide levels exceeding 41% are not considered to be applicable to typical CCPs. Additional information related to CCPs with elevated levels of calcium oxide (>41%) are addressed in Section 5.5.1. 7 Although the maximum level of calcium sulfate in any of the ash formulations evaluated was ~6%, the ACAA technical committee indicated that calcium sulfate may be present in a CCP formulation up to a level of 12% due to the use of inorganic calcium compounds that may be used as pollution control additives. 8 Although the ASTM C618 limit for carbon in ash for concrete is 6%, unburned carbon can be found at higher levels in some CCPs with levels as high as 20% in ash from cyclone boilers. The carbon level is often measured by the Loss on ignition (LOI) value. Levels above 6% are not considered to be representative of typical CCP compositions. Additional information related to CCPs with elevated levels of carbon (>6%) are addressed in Section 5.5.2.

4.2 ANALYTICAL METHODOLOGY General information on the composition associated with the various forms of CCPs considered in the development of this SDS Guidance are note in Section 4.1 above. It is important that each CCP be analyzed to determine its specific composition and individual component concentrations to generate a SDS that accurately reflects the hazards associated with that CCP. Appendix F provides a list of analytical techniques and methods that may be employed to assess the composition of the CCP and the potentially hazardous components that may either require disclosure on the SDS and/or affect the final CCP hazard classification(s). The analytical methods presented in Appendix F will identify and quantitate the levels of compounds typically present in a CCP composition as identified in the development of this SDS Guidance Document.3, 4, 5 Other substances deemed significant for evaluation by the United States Geological Survey (USGS) may also be evaluated for using compound-specific methods. Those compounds with associated methods include: mercury (direct mercury analyzer), selenium (hydride generation atomic absorption), chlorine (total chlorine analyzer) and sulfur (LECO SC 632) (Affolter, 2011). 4.3 COMMON PITFALLS IN COMPOSITION DETERMINATION/DISCLOSURE The composition of CCPs can be determined using varying methods such as X-Ray Fluorescence analysis (XRF), X-Ray Diffraction analysis (XRD), Inductively Coupled Plasma analysis (ICP) or other methodologies as found in Appendix F. The material characteristics and the test method must be considered when interpreting the raw analytical data in order to provide proper context for the results. It is recommended that a chemist or material scientist familiar with the coal combustion process be consulted to evaluate and interpret the analytical data to determine the CCP composition, as the results may be reported in terms of substances that are not actually present in the product. For example, some methods do not distinguish between various sulfur compounds and simply report all detected sulfur as sulfur trioxide, which is a gas not found in solid CCPs. Other examples of potentially misleading reporting conventions are presented in Table 2. These substances should not be directly used to determine the overall CCPs hazard classification, but rather should be evaluated by a chemist or materials scientist familiar with CCP compositions to assess the actual substances that may be present in the CCP.

3 The techniques/methods are not recommended by ACAA or any member companies, but may be used to determine the composition of a CCP. Other methods may be employed to assess individual CCP compositions. 4 The test methods specified result from input from ACAA members and the following ASTM Standards: C618-12a: Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete, D4326-13: Standard Test Method for Major and Minor Elements in Coal and Coke Ash by X-ray fluorescence, D311/311M-13: Standard Test Methods for Sampling and Testing Fly Ash or Natural Pozzolans for Use in Portland-Cement Concrete and D114-15: Standard Test Methods for Chemical Analysis of Hydraulic Cement. 5 Other compounds not identified as potentially present in a typical CCP composition during the development of this SDS Guidance may require additional techniques/methods not included in Appendix F.

5. Hazard Classification OSHA HCS 2012 generally aligns with the methodology set forth in the UN GHS, Revision 3 to assign appropriate physical and human health hazard categories to substances and mixtures (HCS, 2012). Hazard classes implemented from the GHS Guideline are: explosives flammable gases/aerosols gases under pressure flammable liquids/solids self-reactive substances/mixtures pyrophoric liquids/solids self-heating substances/mixtures oxidizing liquids/solids/gases organic peroxides metal corrosivity acute oral toxicity

dermal and inhalation toxicity aspiration hazard skin and eye corrosion/irritation respiratory or dermal sensitization mutagenicity carcinogenicity reproductive toxicity specific target organ toxicity-single

exposure specific target organ toxicity-repeated

exposure Within each hazard class, a set of criteria has been established by GHS to classify the substance or mixture into a specific hazard category (HCS, 2012, Appendix A and B). OSHA HCS 2012 also includes additional hazard classes that are not derived from the GHS Guideline. These include combustible dust, pyrophoric gases, and simple asphyxiant classifications. The pyrophoric gases and simple asphyxiant classifications do not apply to CCPs based on their physical form. However, the combustible dust classification cannot be ruled out based on the product form considering that some fly ash might contain high levels of unburned carbon. Signal words, hazard statements, precautionary statements and pictograms are then assigned to the substance or mixture as required by OSHA HCS 2012 based on the assigned hazard categories. To assign a hazard classification per OSHA HCS 2012, data on the actual product (in this case the final CCP) is first considered. If data on the CCP is inadequate to assess the hazard or is unavailable, information on similar materials (defined as read-across) or individual component data are used to assess the hazard classification. Note: Environmental/ecological hazard classifications are not mandatory under OSHA HCS 2012 and are not required for SDS development. This guidance document does not include the review and classification for CCPs with respect to environmental/ecological endpoints. 5.1 DATA SUPPORTING THE CCP HAZARD CLASSIFICATIONS Hazard classifications of the CCPs were based on data provided by registrants of “ashes (residue), coal.” This includes fly ash and fluidized bed combustion (FBC) ash under the European Union’s (EU’s) Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation as compiled in dossiers made available through the ECHA Dissemination Portal (ECHA, 2010a; ECHA, 2010b). Where applicable, hazard classifications also consider data for specific components such as respirable crystalline silica, identified skin and eye irritants, and pollution control additives that may be added

Although the REACH dossiers provide significant data to assess most OSHA recognized physical and chemical hazards, the carcinogenicity and combustible dust classifications required additional scrutiny based on OSHA HCS 2012 requirements.6 Table 3 provides a summary of the human health endpoints evaluated.

Since the exposure to 1.4 mg/L of respirable coal fly ash particles on three consecutive days for 4 hours/day did not result in mortality and the respirable fraction of ashes (residue) typically does not exceed 20% of the total mass, the registrant determined that the LC50 is expected to exceed 5 mg/L. Based on the HCS 2012 criteria, no classification with respect to acute inhalation toxicity is required.

An acute inhalation toxicity LC50 was determined to be greater than 5.38 mg/L with a Mass Median Aerodynamic Diameter (MMAD) for the product of 2.33 microns after 4-hour exposure to rats. Based on the HCS 2012 criteria, no classification with respect to acute inhalation toxicity is required.

Specific Target Organ Toxicity: Repeated Exposure (STOT-RE)

A long-term repeat inhalation exposure study (180 days) with fly ash dust conducted using rats did not result in significant adverse effects at the highest dose tested (NOAEC = 4.2 mg/m3) after the 180-day exposure period. Responses in the lungs were considered an adaptive response to inhaled particles and not unique to fly ash. As no effects were observed at the highest dose tested, it is not possible to assess the level at which toxicologically significant effects may occur in the rat. Therefore, a STOT-RE classification based on available test data is not possible based on inconclusive evidence. Based on HCS 2012 criteria, no classification with respect to STOT-RE is required.

A long-term repeat oral exposure study (90 days) with 50, 200, and 800 mg/kg/day FBC fly ash conducted using rats reported a NOAEL for males of 200 mg/kg/day. The value was established on the basis of biochemical and histopathological examination. The target organ is the liver. The NOAEL for females was the highest dose tested, 800 mg/kg/day.

5.2 SILICA CCPs may contain both amorphous and crystalline forms of silica. The term “crystalline” refers to the ordered arrangement of silicon and oxygen atoms in the silicon dioxide (SiO2) molecules in a fixed pattern, compared to the disordered and random molecular arrangement defined as amorphous silica. 5.2.1 Amorphous Silica and Aluminosilicates Amorphous silica and the aluminosilicates have not been linked to significant health effects. No specific hazard classifications associated with the chemical nature of these substances is attributable to the CCP. It is recognized however that the presence of these substances in a CCP dust may contribute to transient respiratory irritation classification of CCP assigned herein as a Single Exposure – Specific Target Organ Toxicity, Category 3 (Respiratory Irritation). 5.2.2 Crystalline Silica The most common forms of crystalline silica are quartz, cristobalite, and tridymite. This section serves to provide information related to: (1) the presence of crystalline silica and respirable crystalline silica (RCS) in CCPs, (2) health effects data, both epidemiological and animal associated with exposure to RCS, (3) recent regulatory rulings as they affect the data interpretation and (4) the implications for the hazard classification of CCPs containing RCS, per OSHA HCS 2012. 5.2.2.1 Presence of Crystalline Silica and RCS in CCPs As the temperature within the boiler during the coal combustion process exceeds the melting point of the inorganic fraction of the coal, the fly ash consists mainly of amorphous aluminosilicates. Rapid cooling of the fly ash as it exits the boiler in the flue-gas stream results in vitrification of the non-carbon material and transformation to glassy aluminosilicates. The aluminosilicates are typically a combination of the amorphous silica and aluminum oxide. CCP particles may contain crystalline silica that was a component of the pre-combustion coal, or has either passed through the combustion process unchanged, partially vitrified, or reformed at high temperatures. The amount of free crystalline silica present is dependent on various factors such as (1) the amount of crystalline silica in the coal; (2) the temperature of combustion, and (3) the pollution control technologies utilized (EPRI, 2006a). This free crystalline silica when present in a respirable form has been recognized as a human health hazard upon inhalation. Although the specific toxicological affects associated with crystalline silica and in particular the respirable portion of crystalline silica continues to be a controversial topic among scientists and regulators, a recent OSHA ruling identifies RCS as a Category 1 carcinogen.

Analytical data from the ECHA, EPRI and various ACAA member companies indicate that crystalline silica may be present in CCPs at levels of up to 36% (see Sections 5.1, Table 4, and Section 5.2.2.1). This value however, is insufficient to fully assess the hazards associated with the presence of crystalline silica in the product. To evaluate the human health hazards associated with crystalline silica, it is important to consider not only the form, but also the presence of respirable particles that may be present. The National Institute for Occupational Safety and Health (NIOSH) defines Respirable Crystalline Silica (RCS) as “that portion of airborne crystalline silica that is capable of entering the gas-exchange regions of the lungs if inhaled; by convention, a particle-size-selective fraction of the total airborne dust; includes particles with aerodynamic diameters less than approximately 10 microns (µm) and has a 50% deposition efficiency for particles with an aerodynamic diameter of approximately 4 µm.” (NIOSH, 2002) Recognizing that accurate determination of the particle size is important in understanding potential health effects that may result from exposure to RCS present in CCPs, EPRI developed and investigated the use of a new computer-controlled scanning electron microscopy (CCSEM) methodology as compared to the standard methodology using x-ray diffraction (XRD) to quantitively and qualitatively evaluate RCS size and shape in bulk fly ash samples as well as air/breathing zone samples of workers exposed to fly ash (EPRI, 2006b; 2008). In bulk ash samples, using CCSEM, the amount of RCS ranged from 0.1 to 3.2 volume percent in contrast to the XRD measurements indicating 7.0 to 16.0 weight percent of quartz (EPRI, 2006b). It was concluded that the traditional XRD methodology based on weight percent of total quartz may overestimate the actual concentration of RCS. The CCSEM analysis also compared the number percent particle size distribution (PSD) of the silica particles to a volume-based PSD. Looking strictly at the number percent PSD, most particles fall into the respirable range defined in this study as 4 microns. Number percent PSD gives each particle equal weighting which may not be representative of the contributions of the size and volume of the particles. From the volume PSD, this study observed that most of the volume contained in the silica particles is actually larger than 6 microns in size with only a small fraction (less than 1%) less than 4 microns (EPRI, 2006b). The EPRI study also provided information on the amount of RCS in various airborne dust samples from maintenance activities and ranged from 0.6 to 3.1% as determined by CCSEM (EPRI, 2008). In this study, the CCSEM volume percent RCS levels and XRD weight percent of quartz results were in reasonably good agreement for most airborne samples. In a NIOSH investigation of the potential exposures to crystalline silica as a constituent of the fly ash used in the cement manufacturing process, personal air samples collected from workers found that the levels of respirable dust and quartz (crystalline silica) did not exceed applicable exposure criteria even when the levels of total dust were found to exceed acceptable levels in effect at that time as well as recently updated RCS OELs of 0.05 mg/m3 (NIOSH, 2001). Therefore, even under dusty conditions in the workplace, the use of fly ash by workers in the cement plant did not result in significant exposure to RCS. For purposes of the CCP hazard classification and SDS development, the CCSEM results for RCS will be considered representative of the free respirable crystalline silica rather than using the total crystalline silica/quartz weight percent levels (based on XRD) or assuming that all silicon dioxide in the CCP is respirable. In his 2010 review to provide rationale for the Classification, Labelling and Packaging requirements for RCS according to Regulation (EC) No. 1272/2008, Morfeld cites a coal mine dust evaluation which concluded that the silicosis risk is expected to occur at quartz dust contents within the

FINAL AUGUST 2018

25

respirable mixed dust of 10% or higher. Therefore, the hazard classification for CCPs will be based on a level of RCS in the ranges of 0.1 to 10% to bracket the levels reported by EPRI (2008). 5.2.2.2 Health Effects The health effects associated with crystalline silica have been linked to the fraction of free airborne crystalline silica that when inhaled can penetrate the nose and upper respiratory tract and deposit into the deep tissues of the lung. These effects have been studied extensively for over twenty years in both in vitro and in vivo animal models as well as in epidemiological occupational studies on workers exposed to RCS. As a result of the findings from these studies and overall risk assessments by various scientific and technical bodies, the two most common effects associated with exposures to RCS include silicosis and carcinogenicity. Recent reviews sponsored by the Industrial Minerals Association (IMA)-Europe (Morfeld, 2010), EPRI (EPRI, 2006a), the American Chemistry Council (ACC, 2014), and the new OSHA Final Rule for RCS (OSHA, 2016) were used as the primary sources for assessing the health effects of RCS in CCPs. These reviews contained the most up-to-date information and utilize current risk assessment methodologies. It is noted however, that OSHA’s assessment of the toxicological effects of RCS did not result in the same conclusions of the IMA (Morfeld, 2010), the ACC (ACC, 2014) or EPRI (EPRI, 2006a) even though the same (or similar) data was reviewed. 5.2.2.2.1. Silicosis For many years, the prolonged inhalation of fine dust containing RCS has been recognized as a causative agent of silicosis (IMA, 2014a). Silicosis is defined by fibrotic changes (scarring) that affect the ability of the lung to exchange gases (MSHA, 2008). In terms of OSHA HCS 2012, substances or mixtures resulting in silicosis would be classified for Repeat Dose Toxicity – Specific Target Organ Toxicity (Lungs) when the level of RCS exceeds the threshold for this classification of 1%. Silicosis has primarily been observed in workers from industries where significant exposure to RCS occurs over long periods of time, typically over several to many years. Exposures to RCS in the natural environment are much lower than those found in the workplace and have been noted to be insufficient to cause this disease. Silicosis is therefore considered to be an occupational disease. Epidemiological and animal studies have shown clear a positive dose-response relationship between occupational exposure to RCS and silicosis. Inhalation studies with rats show a definite fibrogenic pulmonary response after repeated RCS exposure. Based on a review of epidemiological morbidity studies, the prevalence of silicosis is the most pronounced dose-response effect identified in workers exposed to RCS as compared to other endpoints such as chronic obstructive pulmonary disease (COPD), autoimmune diseases, or lung cancer. Researchers have concluded that no other non-malignant health effect is as specific and so clearly linked to RCS as silicosis (Morfeld, 2010). It is important to note; however, that the United States has shown a decline of more than 90% in the overall silicosis mortality rate from 1968-2010 resulting with death rates decreasing from 1,065 in 1968 to 101 in 2010 (ACC, 2014). CDC has suggested that many of the deaths attributed to RCS in the early years occurred prior to the implementation of the first permissible exposure limits for RCS established by OSHA in the early

1970s (ACC, 2014).7 This indicates that low levels of RCS do not result in silicosis and the current worker exposure levels are protective (ACC, 2014). Furthermore, silicosis typically appears only among workers exposed to levels of RCS above the original OSHA Permissible Exposure Limit (PEL) for RCS for extended periods of time. ACC provided summaries of data that show crystalline silica exposures in excess of OSHA’s existing PEL are averaging around 30% or more each year. This led Dr. Peter Morfeld to conclude that these significant overexposures are likely, “the driving cause of cases of silicosis, lung cancer, and other silica-related diseases reported in registries, screening programs and epidemiological studies and presumably is the reason why silicosis has not yet been eliminated from American workplace (ACC, 2014).” EPRI cites the American Conference of Governmental Industrial Hygienists (ACGIH) 2004 report on crystalline silica in which the ACGIH acknowledges that workers protected at the Threshold Limit Value (TLV) of 0.05 mg/m3” have not shown changes in life expectancy or lung function, although a small percentage may develop radiographic changes consist with pneumoconiosis (i.e., accumulation of dust in the lungs)” (EPRI, 2006a).8 With respect to CCPs, fly ash was tested in long-term inhalation exposures in rats and was found to result in minor adaptive effects in the lungs more generally associated with particulate dusts and tissue damage consistent with a fibrosis such as silicosis, but “the relative dose required to produce these effects was very high, and likely not representative of workplace exposures even under extreme conditions” (EPRI, 2006a). These findings are also in agreement with research performed by Meij, et. al., in which demonstrated that crystalline silica can be present as free individual particles or enclosed within glassy particles. Although it was found that more free than enclosed crystalline silica may exist, the free amount is dominated by larger particles considered to be non-respirable. This led the researchers to conclude that the vast majority (approx. 85%) of the RCS present in fly ash was found enclosed within glassy particles and thus not available to produce the surface-related, negative effects attributed to RCS (Meij, 2000). 5.2.2.2.2. Carcinogenicity The most controversial endpoint related to RCS exposure is the potential cancer risk due to airborne exposures. In 1997, the International Agency for Research on Cancer (IARC) classified RCS dust in the form of quartz or cristobalite as a Group 1 Human Carcinogen (carcinogenic to humans). The expert Working Group expressed difficulty in coming to this decision as indicated in this explanatory note preceding the conclusion: "In making the overall evaluation, the Working Group noted that carcinogenicity in humans was not detected in all industrial circumstances studied. Carcinogenicity may be dependent on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution of its polymorphs. Crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1). Amorphous silica is not classifiable as to its carcinogenicity to humans (Group 3)" (IARC, 1997; EPRI 2006a) Interestingly, the

7 The original OSHA PELs for crystalline silica were established based on the form of the crystalline silica, with the TWA for total quartz of 30 ÷ (%SiO2+2) mg/m3, and a PEL for RCS of 10 ÷ (%SiO2+2) ) mg/m3. 8 A recent OSHA ruling lowered the PEL for crystalline silica to 0.05 mg/m3 (OSHA 2017). ACGIH recently reduced their TLV for RCS to 0.025 mg/m3.

27

same working group of experts classified coal dust, which may contain up to 15% crystalline silica, as an IARC Group 3 carcinogen (not classifiable as to its carcinogenicity to humans) (IMA, 2014a).9 Following the IARC classification, the U.S. National Toxicology Program (NTP) also classified RCS as known to be a human carcinogen in the Ninth Report on Carcinogens in 2000 citing “sufficient evidence of carcinogenicity from studies in humans indicating a causal relationship between exposure to RCS and increased lung cancer rates in workers exposed to crystalline silica.” (NTP, 2016). The ACGIH listed respirable crystalline silica as a suspected human carcinogen in 2000, lowering the TLV to 50 ug/m3. In 2006, ACGIH lowered the TLV for respirable crystalline silica to 25 ug/m3 (OSHA, 2016). EPRI (2006a) generated a summary of mechanistic studies evaluated after the IARC 1997 classification that observed that crystalline silica is not directly genotoxic. The suggested mode of action for how RCS causes lung cancer has instead been established as an indirect or secondary effect of the silicosis (Morfeld, 2010). Evidence for this mode of action is supported by the negative mutagenicity studies conducted with fly ash and FBC fly ash that may also contain RCS. The epidemiological data further indicates that the carcinogenic effects associated with occupational RCS exposures are limited to the lung with no evidence of significant causality of other cancers. It is also important to note that the only animal species to produce lung tumors in response to RCS was the rat; no carcinogenic effects were seen in mice, hamsters or guinea pigs, which has led some researchers to conclude that the response in the rat is specific to that species (EPRI, 2006a). After the IARC and NTP classifications, several additional studies of lung cancer in RCS workers have been published, with additional reviews of existing animal toxicology and epidemiology data in human workers exposed to RCS conducted by various researchers and organizations. These more recent studies reflect updates from supplementary follow-up, data from nested case-control studies of previously assessed cohorts, or new results based on refined exposure assessments or adjustment for confounders. The conclusions from these more recent studies have called into question the validity of the carcinogenic risk of RCS from occupational exposures (EPRI, 2006a; ACC, 2014). In 2009, IARC established a new Working Group of 27 scientists from eight countries to conduct an additional review of the available scientific literature; this group reaffirmed the original classification of RCS dust as a Group 1 Human Carcinogen (IARC, 2012). This reassessment focused on quantitative exposure data from occupational exposures as well as a summary of findings from eight published meta-analyses reports of lung cancer. A member of this Working Group further analyzed the IARC database as well as some additional studies (Gamble, 2011). Gamble found that the association between RCS and carcinogenicity was consistently weak in the majority of the studies and showed a lack of exposure response trends. He concluded that the “weight of evidence from occupational epidemiology does not support a causal association of lung cancer and silica exposure, which is contrary to the IARC conclusion using essentially the same data”(Gamble, 2014). The ACC provided a review and summary of the epidemiological studies associated with crystalline silica with input from various experts and concluded that “the hypothesis that crystalline silica exposure is 9 Substance which cannot be classified as to its carcinogenicity due to inadequate evidence in humans and animals.

FINAL AUGUST 2018

28

causally associated with increased risk of lung cancer was – and has remained – controversial and unsettled. Epidemiological studies have been negative as often as they have been positive; exposure response trends have generally been absent even in the studies that appeared to be positive; and the effects of confounding factors such as smoking or other occupational exposures and/or the necessity of a mediating silicotics response cannot be ruled out where increased risks have been found.” (ACC, 2014). Environment Canada and Health Canada concluded the following in a recent assessment of potential health risks associated with exposure to quartz and cristobalite, “At this time, within the epidemiology literature there is debate on whether human workplace exposure to silica which does not cause silicosis can be associated with lung cancer… Thus, the question of whether silica exposure, in the absence of silicotic response, results in lung tumours remains unanswered.” (Environment Canada, 2013). Morfelds’ review identified lifestyle factors (especially smoking) and socioeconomic status as confounding factors in the excessive lung cancer risk and mortality patterns associated with worker exposure studies of RCS (Morfeld, 2010). He also recognized that lung cancer risks were observed only under high occupational exposure conditions. These observations, based on studies published in recent years, led EPRI to conclude that “given the lack of a direct association between crystalline silica and lung cancer among workers exposed to crystalline silica, there should be no concern regarding the potential carcinogenicity of crystalline silica in coal fly ash.” (EPRI, 2006a) 5.2.2.2.3. Relationship between Silicosis and Lung Cancer The relationship between silicosis and lung cancer is complex, as most studies have depended on cohorts of compensated workers with silicosis (silicotics) leading to a positive bias in results and conclusions. Recent literature provides evidence supporting the relationship between silicosis and lung cancer (EPRI, 2006a). In a meta-analysis study of workers exposed to RCS, there was no evidence that non-silicotics suffered from higher lung cancer risks especially after smoking habits were considered (Morfeld, 2010). IMA Europe has concluded that silicosis is the primary effect resulting from significant exposure to RCS and that it is a consequence of inflammation in the lung. Although excess cancer risks are observed in silicotics, the mechanistic role of silicosis in the development of lung cancer is not clear; additional data is necessary for an exact determination. ACC indicates in their review that studies, “supporting an association between silicosis and increased lung cancer risk (while not conclusive) are far more compelling than the mixed and inconclusive results of studies evaluating the association of silica exposure and lung cancer risk in the absence of silicosis or where silicosis status was unknown.” (ACC, 2014) Independently, Morfeld concluded that minimizing the risk of silicosis will also mitigate the lung cancer risk due to RCS (Morfeld, 2010). 5.2.2.3 Recent OSHA Ruling on RCS For purposes of this document, it is imperative to look not only to scientific documentation and technical interpretations of the available data, but to regulatory rule making and the associated requirements. The recent OSHA Final Silica Rule must be considered in the assignment of hazards to CCPs and information provided in the associated SDS and labels per OSHA HCS 2012. OSHA promulgated the Final Rule for Occupational Exposure to Respirable Crystalline Silica (RCS) (Final Rule) on March 25, 2016 (Federal Register Volume 81, No. 58, Pages 16285-16890). The Final Rule was based on OSHA’s extensive literature review and risk assessment of the health effects associated with

Page 30: AMERICAN COAL ASH ASSOCIATION COAL COMBUSTION … · Under HCS 2012, it is still the responsibility of the chemical manufacturer/importer to assess the hazards of products distributed

FINAL AUGUST 2018

29

exposure to RCS that determined that employees exposed to RCS at the previous PEL are at increased risk of developing silicosis and lung cancer. As a result, the Final Rule establishes a new PEL of 50 micrograms of RCS per cubic meter of air (50 ug/m3) as an 8-hour time-weighted average. In addition, the Final Rule includes other provisions to protect employees such as requirements for exposure assessment, methods for controlling exposure, respiratory protection, medical surveillance, hazard communication, and recordkeeping (OSHA, 2016). To support this change, OSHA conducted an extensive search and review of the peer-revised scientific literature on the health effects of inhalation exposure to crystalline silica. OSHA also used suitable exposure-response data from epidemiological studies to estimate quantitative risks for lung cancer and silicosis mortality. A draft document outlining OSHA’s findings on the health effects and the resulting quantitative risk assessment was submitted to a panel of scientific experts for independent peer review and subsequently opened for public comment. OSHA concluded in its Draft Rule for Occupational Exposure to Respirable Crystalline Silica (Draft Rule) that exposure to RCS causes silicosis and is the only known cause of silicosis. For the lung cancer endpoint, OSHA reviewed 60 epidemiological studies covering more than 30 occupational groups and concluded that the data provided evidence that exposure to RCS increases the risk of lung cancer among workers; this is consistent with the IARC Group 1 Human Carcinogen classification (OSHA, 2016). OSHA further concluded that RCS is an independent risk for lung cancer mortality and that silicosis is not a necessary precursor to lung cancer (OSHA, 2016). OSHA received both negative and positive comments and testimony regarding their findings and the proposed draft rule. OSHA indicated that the peer reviewers found that OSHA was reasonable in its interpretation of the studies and the health effects conclusions were generally well founded (OSHA, 2016). OSHA “believes that the external, independent peer-review process supports and lends legitimacy to its risk assessment methods and findings.” Stakeholders such as the American Public Health Association (APHA) and the National Consumers League (NCL) commented, “OSHA has thoroughly reviewed and evaluated the peer-reviewed literature on the health effects associated with exposure to respirable crystalline silica. OSHA’s quantitative risk assessment is sound.” Dr. Mirer, one of OSHA’s expert peer reviewers who served on several National Academy of Sciences committees setting risk assessment guidelines, further concluded that OSHA’s risk analysis is “scientifically correct, and consistent with the latest thinking on risk assessment.” (OSHA, 2016). Other stakeholders such as the American Chemistry Council (ACC) provided extensive comments and criticisms regarding the epidemiological studies used to support the risks and causality associated with RCS, lung cancer, and silicosis. In addition, ACS claimed that the methodology used to determine the risk assessment numbers were invalid as the uncertainty and confounding factors applied to the study results were not accounted for appropriately. The OSHA Final Rule incorporates responses and comments to the Draft Rule, OSHA’s final conclusion on the health effects of RCS and updated PELs. After its review of stakeholder comments, OSHA indicated that it“…did not find them adequate to alter OSHA’s overall conclusions of health risk…OSHA believes that the external, independent peer-review process supports and lends legitimacy to its risk assessment methods and findings.” (OSHA, 2016)

FINAL AUGUST 2018

In the Final Rule OSHA states that, “Multiple organizations with great expertise in this area, including the American Cancer Society, submitted comments supporting the thorough and authoritative nature of IARC’s findings regarding silica’s carcinogenicity (e.g., Document ID 1171; 1878). OSHA places great weight on the IARC and NTP classifications and, based on their findings, concludes that the carcinogenic nature of crystalline silica dust has been well established.” Relative to the updated PELs, OSHA concludes “that long-term exposure at and above the previous PELs would pose a significant risk to workers’ health, and that adoption of the new PEL and other provisions of the final rule will substantially reduce this risk.” (OSHA, 2016) 5.2.2.4 RCS Carcinogenicity Classification: Implications on CCP Hazard Classification The reviews and hazard assessments of the health effects of RCS, as summarized in section 5.2.2.2, indicate that most researchers and regulators agree that RCS may causes systemic target organ toxicity after repeated exposures (STOT-RE) in humans in the form of silicosis and that it should be classified as a STOT-RE Category 1 (Lungs) based on the potential silicotic effects. The identification of RCS as a carcinogen; however, varies from not classified to the most severe classification, Carcinogen Category 1A per OSHA HCS 2012 criteria (Gradient, 2015a). The IMA-Europe position paper, while supporting the STOT-RE classification, concluded that no carcinogenicity classification for RCS is warranted (when silicosis is defined as the endpoint for classification) (IMA, 2014b). However, both IARC and NTP have recently reevaluated the classification of RCS and confirmed that RCS is a human carcinogen. Although levels of RCS in the fly ash and FBC fly ash evaluated in support of European Union REACH registration and summarized in Section 5.1 above were not disclosed, RCS may be present in CCPs. As a result, the toxicology testing performed for REACH registration of CCPs as described in Section 5.1 confirm the IMA Europe conclusions based on the negative mutagenicity studies and minimal effects observed in repeated inhalation studies in animals. The EPRI analysis also suggests that carcinogenic effects are not a concern from exposures to CCPs (EPRI, 2006a). The various assessments of RCS and their associated conclusions summarized in section 5.2.2.2, which considered free RCS are further compounded when the availability of the RCS in a UVCB substance such as a CCP is taken into consideration. For example, as noted in Section 5.2.2.2.2, IARC classified coal dust, which often contains greater than 0.1% RCS, as an IARC Group 3 carcinogen (not classifiable as to its carcinogenicity to humans) (IMA, 2014a).10 This is likely due to a lack of bioavailability of the RCS within the coal dust; RCS is generally bound in the amorphous aluminosilicate matrix of coal and associated CCPs. Data generated by an ACAA member company has shown that fly ash derived CCP materials tested using scanning electronic microscope techniques resulted in less than 0.1% crystalline silica even though the total crystalline silica as determined by XRD was greater than 0.1% (Confidential ACAA Member Company, 2017). This suggests that the bioavailability of the RCS may be dependent on the matrix or structure it is embedded in and limits potential for exposures. Regardless of the scientific debate on the appropriate hazard classification of RCS and UVCB substances and mixtures containing RCS, the OSHA Final Rule states that RCS is a Carcinogen Category 1A and Repeat Dose STOT Category 1 (Silicotic lung effects). On the basis of OSHA’s classification, and the lack

of definitive toxicological data on carcinogenicity of the final CCPs, CCPs that contain RCS at or above 0.1%, must be evaluated to apply the appropriate classification based on the level of RCS present. Therefore, CCPs containing RCS11 in the form of an identified impurity, additive or individual constituent will be classified under HCS 2012 as: Not classified, when the RCS concentrations is below 0.1% in a CCP;

Carcinogen Category 1A, when the RCS concentrations is between 0.1 and 1% in a CCP; or

Carcinogen Category 1A and STOT RE Category 1, when the RCS concentration is greater than or equal to 1% in a CCP.

5.3 CCP COMPOSITION VARIATIONS THAT IMPACT HAZARD CLASSIFICATIONS 5.3.1 Irritation/Corrosivity Multiple substances classified either as skin or eye irritants may be present in the CCPs naturally or due to the use of pollution control additives. The presence/level of these substances in the fly ash and FBC ash formulations evaluated for REACH registration purposes was evaluated to determine if these substances: 1) were included in the formulations tested at similar levels; 2) may be present at different concentrations than those tested; or 3) are unique to the information gathered during the course of this project on CCPs. If these individual components were present at higher concentrations or were not noted in the tested products, the potential contribution to the hazards of the formula and the need for additional hazard classifications for the ashes was assessed. The individual components (natural and additive based) classified as either skin or eye irritants or skin corrosive substances are presented in Table 5. The table also specifies the classification of the individual substances with the anticipated maximum levels likely to be present in the CCPs based on a review of CCP formulations tested under REACH, data from ACAA member companies, publicly available sources of CCP composition data and information from industry experts. Table 5: Example Skin/Eye Irritants or Corrosive Substances that MAY be present in the typical CCP1

Notes: 1 This table represents irritating or corrosive substances at the maximum level that MAY be present in CCPs based on compositional information submitted by ACAA member companies or identified in technical publications.

11 It has been concluded that “…there is no evidence that the health effects associated with respirable crystalline silica exposures are caused by other dust fractions, by other occurrences of crystalline silica, or by other routes of exposure to crystalline silica” (Morfeld, 2010). Therefore, only the respirable fraction of crystalline silica was considered in development of the GHS classifications of the CCPs and subsequent SDS development.

2 When the Calcium Oxide levels are determined by XRF analysis, the presence of calcium aluminosilicate, and other calcium species in the form of sulfate, carbonate, chloride, etc. may falsely elevate the level of CaO reported.

As mentioned previously, hazard classification per the OSHA HCS 2012 follows a hierarchy with the classifications based first on actual product testing; in the absence of those data, read-across to data on similar products is used and finally data on individual components of the product. Although data on both a representative fly ash and FBC ash are available for skin and eye irritation, there are distinct differences in the results from the various studies. A review of the formulations indicate that this is likely due to different levels of some of the ash components. A comparison of the compositional and toxicology data between these two materials demonstrates that: The fly ash tested for REACH registration purposes was not irritating or corrosive to skin or eyes;

however, the exact level of calcium oxide in the sample tested was not provided and cannot be confirmed as representative of the ACAA member formulations.

Two FBC fly ash compositions tested under the REACH registration showed variable results.

– The FBC fly ash composition with a total calcium oxide level of 35.65% (free calcium oxide level of 19.91%) was determined to be:

An eye irritant, Category 2A; but

Non-irritating to skin.

– The FBC fly ash composition with a total calcium oxide level of 19.46% (free calcium oxide level of 8.41%) was determined to be:

Non-irritating to skin; and

Non-irritating to eyes. Notes: 1. See Section 5.1, Table 3 for additional information. 2. The level of total calcium oxide reported in analytical data may be falsely elevated based on the presence

of other compounds in the ash such as calcium aluminosilicate, and other calcium species in the form of sulfates, carbonates, or chlorides.

Based on the data reviewed, the level of calcium oxide was determined to be the primary driver for the skin/eye hazard classifications. The following conclusions can be made: CCPs with levels of total calcium oxide at or below 20% or, if determined, free (reactive) calcium

oxide at or below 8%, would NOT be classified for either skin or eye irritation.

CCPs with levels of total calcium oxide above 20% but less than 41% or, if determined, free (reactive) calcium oxide above 8% but less than 20%, would be classified as an Eye Irritant Category 2A, but not as a skin irritant.

Note: If free CaO in the CCP is determined, that level should be used to assess the classification of the CCP as an eye irritant. Where data on the free CaO has not been assessed, total CaO as determined by XRF analysis, should be used to determine the irritation classification of the CCP.

5.3.2 Acute Toxicants Multiple substances classified as acutely toxic may be present in the CCPs naturally or due to the use of various pollution control additives. The level of the identified acutely toxic substances in a typical CCP was evaluated in consideration of the OSHA HCS 2012 classification criteria and the lack of classification from the testing of a fly ash and two FBC ashes (Section 5.1, Table 3) to determine if the presence of these substances could result in additional hazards associated with the CCP when present. The individual components (natural and additive based) classified as acutely toxic (and the route of exposure: oral, inhalation or dermal) are presented in Table 6. The table provides the hazard classification associated with each substance as well as the maximum level present in the CCPs based on a review of the formulation data from ACAA member companies and various publicly available sources by the industry’s technical experts. Table 6: Acutely Toxic Substances that MAY be present in CCPs1

Substance Source Typical CCP

Level Classification

Calcium oxide X X <41% Acute Oral Toxicity – Category 4

Magnesium sulfate X <2%

Acute Oral Toxicity – Category 4 Acute Inhalation Toxicity – Category 4 Acute Dermal Toxicity – Category 4

Manganese dioxide X <1% Acute Oral Toxicity – Category 4 Acute Inhalation Toxicity – Category 4

Note: 1 This table is not inclusive of all acutely toxic substances that may be present in all CCPs. It represents acutely toxic substances that MAY be present in a typical CCPs at levels that would require consideration in the hazard classification of the CCP. These substances were determined based on compositional information submitted by ACAA member companies or otherwise identified in technical publications.

Using these data and the calculation methodology detailed in OSHA HCS 2012, the presence of these substances at the levels identified in Table 6 would not result in a classification of any typical CCPs for acute toxicity per OSHA HCS 2012. 5.3.3 Substances Defined as Toxic to Reproduction Bromide salts may be present in the final CCP when sodium or calcium bromide is introduced as a pollution control additive in the coal combustion process. Typical additive levels for these substance is 2% as provided by ACAA member company representatives. A review of reproductive toxicity data on sodium bromide (as a representative inorganic bromide salt) indicates that bromide salts may result in reproductive toxicity as well as developmental effects (HSDB 2015; CA EPA 2001). This data would require that bromide salts when present at ≥0.1% be considered during the CCP hazard classification with the final CCP product classified as Toxic to Reproduction Category 2 per OSHA HCS 2012.

FINAL AUGUST 2018

34

As inorganic bromide salts were not noted as present in the fly ash or FBC ashes tested for REACH registration (Section 5.1, Table 3), the use of bromide salts as a pollution control additive will result in the overall CCP being classified as Toxic to Reproduction, Category 2, unless analytical data is available showing that the level of the salts is <0.1%. If this test data is available, no classification is required. 5.3.4 Single Exposure – Specific Toxic Organ Toxicity A large part of the identified CCPs compositions consist of substances present in a dust matrix. As the CCP dust itself may result in mechanical irritation of the respiratory tract, the CCPs would be classified as a Specific Toxic Organ Toxicity-Single Exposure (STOT-SE), Category 3 (respiratory irritation). 5.4 FINAL CCP HAZARD CLASSIFICATION When regulatory requirements, the physical and toxicological data of fly ash, CFB fly ash, and available data on individual components are considered, multiple hazard classifications may be applicable to the typical CCP composition based on component levels. The various classifications that are or may be applicable to a CCP based on component compositions are detailed below along with the rationale for applying those classifications. Specific Target Organ Toxicity (STOT), Single Exposure (SE), Category 3 (Respiratory Irritation)

Due to the overall level of aluminosilicates, calcium oxide, and the form of the CCP as a dust, it is recommended that all CCPs be classified as a STOT-SE (Respiratory Irritation) based on mechanical irritation.

Carcinogen Category 1A

When the level of RCS is undetermined or when the RCS is present at ≥0.1%, the CCP would be classified as a Carcinogen Category 1A. This classification is primarily based on the recently updated OSHA Silica Rule (OSHA, 2016) which classifies RCS as a Carcinogen Category 1. OSHA HCS 2012 indicates that all OSHA defined carcinogens must be considered in the overall CCP classification when present at ≥0.1%.

Specific Target Organ Toxicity (STOT), Repeat Exposure (RE), Category 1

When the level of RCS is undetermined or when the RCS is present at ≥1%, the CCP would be classified as a STOT-RE Category 1 (lungs). This classification is based on a review of available toxicological and epidemiological data on RCS that support the classification due to silicotic effects.

Eye Irritation, Category 2A

Multiple eye irritants were identified as possible components of a typical CCP formulation. When the presence of these substances was critically evaluated, it was determined that the level of calcium oxide was the primary driver of this hazard. The final eye irritation category that would apply to a CCP is therefore dependent on the level of CaO present. Calcium oxide is classified as a Skin Irritant Category 2 and an Eye Irritation - Category 1.

Using data available from REACH registration of CCPs it was determined that CCPs with levels of total CaO greater than 20% but less than 41% total calcium oxide, or greater than 8% but less than 20% free CaO, would be classified under OSHA 2012 as an Eye Irritant, Category 2A.

Notes:

1. No skin irritation classification applies to the CCP when the level of CaO is below 41% (total), or 20% (free).

2. CCPs with levels of total CaO at or below 20% (total) or, if determined, free (reactive) CaO ≤8%, would NOT be classified for eye irritation.

Toxic to Reproduction, Category 2

CCPs should be classified as Toxic to Reproduction, Category 2 classification if sodium bromide or other pollution control additives containing inorganic bromide salts are incorporated into the CCP process and

– The level of bromides is ≥0.1%; or

– No data are available on the level of bromides in the final product.

Note: Per OSHA HCS 2012 Appendix A, when a reproductive toxicant is included at a level of greater than or equal to 0.1%, the final product should also be classified as Toxic to Reproduction. Sodium bromide and other related bromide salts are classified as reproductive toxins.

Carcinogenicity, Category 1A

CCPs with an unknown level of RCS or with an RCS level of >0.1% are classified as a Carcinogen, Category 1A.

Note: In OSHA’s Final Rule, RCS has been defined by OSHA as a Carcinogen, Category 1A. HCS 2012 indicates that all OSHA defined carcinogens must be considered in the overall product classification.

Table 7 highlights the hazard classifications that may be applicable to typical CCPs; these classifications were derived based on data provided from ACAA member companies on CCP compositions considering the hazard classifications associated with individual component variations and CCP formulations tested under REACH. The classifications provided are those associated with typical CCP compositions that conform to the specification summarized in Table 1. Table 7: CCP Composition Hazard Classifications 1, 2

Notes: 1 These classifications only apply to CCP formulations that meet the composition specifications detailed in Appendix C. Should a CCP have additional substances present, or have substance(s) above the maximum percentage identified in Appendix C, an evaluation of those differences should be assessed to confirm that one of the classifications defined would still apply. 2 When the Calcium Oxide levels are determined by XRF analysis on pulverized coal ash, the presence of calcium aluminosilicate and other non-CaO calcium species may falsely elevate the level of CaO reported. If the CaO levels are only determined by XRF analysis, the total CaO level should be used to determine the classification of the CCP as an Eye Irritant, Category 2A. If free CaO is determined, the free CaO level should be used to assess the classification of the CCP as an Eye Irritant, Category 2A. 3 The level of inorganic bromide salts may be determined through analytical testing of the CCP or by confirmation that bromide salts are or are NOT used as pollution control additives in the coal combustion process.

The ACAA recognizes that there may be CCPs with compositional variations outside the ranges specified in Table 1 that would result in additional or different hazard classifications other than those specified in Table 7. Section 5.5 provides information on those variations and potential alternative hazard classifications that may need to be considered prior to generation of a specific CCP SDS. 5.5 OTHER CONSIDERATIONS Although the ACAA recognizes that a CCP could have a composition differing from the typical composition provided in Table 1, this guidance document does not cover the SDS development of all potential CCP formulations. Therefore, compositional variations that do not fall within the typical CCP compositional ranges summarized in Table 1 must be considered prior to generation of the SDS. It is the responsibility of individual companies to assess their individual CCP compositions and requirements associated with the development of SDS. The presence of the additional substances or compositional variations that do not fall within the typical CCP compositional ranges in Table 1 may require modification of the SDS including (but not inclusive of): composition information, hazard classification(s), signal words, pictogram(s), hazard and precautionary statements, permissible exposure limits and other associated information. The atypical CCP compositional configurations included in this section are those that have been identified by various ACAA member companies or specified by OSHA. They are not meant to represent all possible configurations that may lead to SDS modifications.

5.5.1 Higher levels of Calcium Oxide Typical CCPs have CaO present at levels of ≤41% or, if determined, free (reactive) CaO at ≤20%; some CCPs however, may have calcium oxide in excess of these levels. If the level of calcium oxide in a CCP is greater than 41% or, if determined, the free (reactive) calcium oxide is greater than 20%, the irritation classifications specified in section 5.2 would be superseded with the following classifications: A Category 1 Eye irritant classification hazard would be assigned to the CCP (in place of a

Category 2 eye irritant classification).

A Category 2 Skin Irritant classification would be added. Information associated with these more severe classifications will require adjustments to information in multiple sections of the SDS. 5.5.2 Loss on Ignition Value A large part of the identified CCPs compositions consist of substances present in a dust matrix. Typical CCPs have a residual carbon content of <6%. Based on the potential for elevated levels of residual carbon to be present in the CCPs, the potential for the generation of a combustible dust (as defined by OSHA) was evaluated (OSHA 2013b). A combustible dust classification would most likely apply to CCPs when the carbon content has been inadequately spent, resulting in an Loss on Ignition (LOI) value of >6%. Prior to assigning such a classification however, additional factors may be considered; including product test data, overall product composition and particle size (Amyotte et al 2005; Collette et al 2010). OSHA does not require testing to assign a combustible dust hazard; the classification can be assigned based on available data from deflagration or explosive events, product test data, or published test data on similar materials (OSHA 2013b). No specific testing methodology is specified by OSHA; however, various methodologies are available to assess this property such as ASTM D5373/6316. The applicability of a combustible dust classification is not within the scope of this Guidance as the typical CCP composition defined in Table 1 only includes CCPs with LOIs of ≤6%. CCPs with >6% LOI should be critically reviewed by the individual CCP manufacturer/distributor to assess the need for the combustible dust classification. If deemed appropriate, information associated with classification would need to be added to Section 2 and 3 of the SDS with adjustments to associated information made throughout the SDS. 5.5.3 Beryllium OSHA has recently published a final rule related to beryllium exposures in the workplace. The rule was issued to prevent chronic beryllium disease and lung cancer in workers by limiting inhalation exposure to beryllium and beryllium compounds. According to 29 CFR, section 1910.1024, the standard does not apply to materials containing <0.1% beryllium by weight, where objective data is available showing that exposures will remain below the 8-hour time-weighted average (TWA) of 0.2 ug/m3 and the 15-minute short-term exposure limit (STEL) of 2.0 ug/m3 (OSHA 2017a, OSHA 2017b).

Beryllium concentrations in CCPs are generally lower than 25 ppm (0.0025%) and typically range from 3 – 10 ppm (0.0003-0.001%) (EPRI, 2006c). Consistent with this assessment, recent data from an ACAA member company show beryllium levels in 30 distinct CCPs were less than 6.5 ppm (<0.00065 %) (Confidential ACAA member company data, 2017).

Although the level of beryllium in CCPs has been shown to be consistently two or more orders of magnitude lower that the 0.1% applicable to carcinogens as specified in the rule, no data was available from the document authors regarding occupational exposures to beryllium associated with CCP generation/use. Further, the beryllium particle size distribution within the CCP matrix is not known.

Based on current data, no additional information related to beryllium is recommended for inclusion in CCP SDSs at this time; however, it may be in ACAA member companies best interest to perform occupational exposure testing for beryllium to confirm compliance with the new OSHA Beryllium Rule. Occupational exposure test data below the OSHA PELs would further support the absence of beryllium disclosure on the SDS.

6. SDS Development Information prescribed by OSHA in the HCS 2012 (29 CFR 1910.1200) and associated OSHA guidance was used to develop and generate a SDS for the CCPs (OSHA 2012a, OSHA 2012b, OSHA 2012c, OSHA 2012d, OSHA 2012e, OSHA 2012f, OSHA undated a, and OSHA undated b). The data included is applicable to the development of SDSs for CCP compositions that conform to the typical CCP composition as summarized in Section 4.1, Table 1. Individual CCP hazard classifications that are associated with variations in that typical composition are summarized in Section 5.4 Table 7. 6.1 GENERAL COMMENTS The American National Standard for Hazardous Workplace Chemicals: Hazard Evaluation and Safety Data Sheet and Precautionary Labeling Preparation Standard (ANSI Z400.1, 2010) is referenced in OSHA HCS 2012. ANSI Z400.1 provides recommendations on SDS format that can be used to meet the requirements of OSHA HCS 2012. Its recommendations are used throughout this guidance document to generate the CCP SDS template. These recommendations provide guidance to improve the readability and comprehensibility of the generated SDS including: Use of a vertical (portrait) format on a standard paper size (8-1/2 x 11 inch).

Use of 10 to 14-point simple fonts, with the use of multiple fonts being avoided.

Avoid long strings of text typed in upper-case letters.

Use only common abbreviations and acronyms. Provide full definitions in the legend in Section 16.

Choose commonly used words, but avoid colloquialisms and slang.

Include ample margins so that copying and binding do not cut off information.

Use left justification of text, consistent line spacing and spaces to separate fields and sections.

Avoid footnotes on the SDS. Pertinent information may be placed in parentheses or as a “note” directly following information requiring clarification.

Use Arabic numbers (e.g., 1, 2, 3), where required. It is further noted that the audiences required to acknowledge and understand the information provided in the SDS vary widely and can range from an untrained person requiring general information to highly technical staff. The information conveyed must be sufficiently complete for the technical specialist yet understandable for general use. 6.2 SDS SECTION-BY-SECTION COMMENTS This portion of the Guidance document is partitioned into individual sections required for inclusion in a OSHA HCS 2012 compliant SDS. Under each section (and subsections) the following information is provided: The purpose of the section;

If the RCS level has not been determined, footnote the crystalline silica value to indicate that the respirable portion of the substance in the CCP has not been determined. 3 Aluminosilicates may be in the form of mullite (CAS#1302-93-8); pozzolans, coal ash (CAS#71243-67-9); or aluminosilicates (CAS# 1327-36-2). The form is dependent on the source of the coal and or the process used to create the CCP. Pulverized coal combustion would be more likely to create high levels of pozzolans, coal ash (particularly bottom ash) due to the high heat of combustion while the CFB process would be less likely to generate this glassy aluminosilicate.

Appendix A CCP Safety Data Sheet (SDS) Checklist

CCP SDS Checklist Page 1 of 7 Preparation Date: 2018-01-04

This SDS Checklist was developed to provide ACAA member companies the information necessary to develop a Safety Data Sheet (SDS) for Coal Combustion Products. When used in concert with the SDS Guidance Document and the SDS Template for Coal Combustion Products (CCPs), the checklist can be used by ACAA Member Companies to develop the SDSs required based on Company and product specific information on their CCPs. Prior to developing an SDS using the SDS Guidance Document and associated Appendices, confirm that the CCP formulation meets the composition specifications detailed in Appendix C (Composition Summary Workbook). Should the CCP being evaluated have additional substances present, or have substances above the maximum percentage identified, the SDS Guidance Document should not be used until an assessment of the compositional differences is evaluated to confirm that the compositional differences do not result in additional GHS classifications of the CCP. This checklist specifies the information required/recommended for inclusion in the SDS per the OSHA HazCom 2012 Rule as specified in 29 CFR 1910.1200, the OSHA recognized ANSI Z400.1 Standard (Hazard Evaluation and Safety Data Sheet and Precautionary Labeling Preparation Standard), or recommendations based on expert judgement. An SDS Template that can be used to communicate the necessary information detailed on a Section by Section basis is available as Appendix B to the SDS Guidance Document. Additional information and further guidance on how to populate the SDS, including appropriate information to be provided can be found in the SDS Guidance Document.

Hazard Statement(s):

Precautionary Statement(s):

* Fly ash and other coal combustion products (CCPs) are UVCB substances (substance of unknown or variable composition or biological. Various CCPs, noted as Ashes; Ash; Ash residues; Ashes, residues, bottom; Bottom ash; Bottom ash residues; Waste solids, ashes under TSCA are defined by the US EPA as: “The residuum from the burning of a combination of carbonaceous materials. The following elements may be present as oxides: aluminum, calcium, iron, magnesium, nickel, phosphorus, potassium, silicon, sulfur, titanium, and vanadium.” Ashes including fly ash and fluidized bed combustion ash are identified by CAS number 68131-74-8. The exact composition of the ash is dependent on the fuel source and flue additives composed of a large number of constituents. The classification of the final substance is dependent on the presence of specific identified oxides as well as other trace elements.

1 The test methods defined will identify compounds present in a typical CCP composition (as determined in the ACAA SDS Guidance Document) that are to be considered in the development of final CCP classification and SDS disclosure and development specifications as specified in OSHA HCS, 2012.  Should additional hazardous substances be identified above 0.1%, they must be considered in the product hazard classification and SDS development process. 

2 The aluminum oxide and amorphous silicon dioxide levels should be added together and evaluated as aluminosilicates for reporting purposes. 

3 Silicon dioxide reported under XRF represents total SiO2.  To determine the level of amorphous SiO2, subtract the level of crystalline SiO2 determined by XRD or PLM from the total SiO2 determined from the XRF analysis.
