3 LIST OF LISTS Consolidated List of Chemicals Subject to the Emergency Planning and Community Rightto-Know Act (EPCRA), Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and Section of the Clean Air Act This consolidated chemical list includes chemicals subject to reporting requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA), also known as Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA),the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and section of the Clean Air Act (). This consolidated list does not include all hazardous chemicals subject to the reporting requirements in EPCRA sections 311 and 312, for which material safety data sheets (MSDS) must be developed under the Hazard Communication Standard (29 CFR ). These hazardous chemicals are identified by broad criteria, rather than by enumeration. There are over 500,000 products that satisfy the criteria. See 40 CFR Part 370 for more information. This consolidated list has been prepared to help firms handling chemicals determine whether they need to submit reports under sections 302 and 313 of EPCRA and determine if releases of chemicals are reportable under section 102 and 103 of CERCLA and section 304 of EPCRA. It will also help firms determine whether they will be subject to accident prevention regulations under section. Separate lists are also provided of Resource Conservation and Recovery Act (RCRA) waste streams and unlisted hazardous wastes, of radionuclides reportable under CERCLA and of definitions or explanation of chemical categories listed under EPCRA section 313 and CERCLA. These lists should be used as a reference tool, not as a definitive source of compliance information. Compliance information for EPCRA is published in the Code of Federal Regulations (CFR), 40 CFR parts 355, 370, and 372. Compliance information for CERCLA is published in 40 CFR part 302 and for section is published in 40 CFR part 68. The chemicals on the consolidated list are ordered both by the Chemical Abstracts Service (CAS) registry number and alphabetically. Categories of chemicals which generally do not have CAS registry numbers, but which are cited under CERCLA, have N.A. listed in place of the CAS number. If the category of chemical is an EPCRA section 313, then the section 313 category code is also included in the CAS number column. The lists include chemicals referenced under five federal statutory provisions, discussed below. More than one chemical name may be listed for one CAS number because the same chemical may appear on different lists under different names. For example, for CAS number , the names toxaphene (from the section 313 list), camphechlor (from the section 302 list), and camphene, octachloro-(from the CERCLA list) all appear on this consolidated list. The chemical names on the consolidated lists generally are those names used in the regulatory programs developed under EPCRA, CERCLA, and section, but each chemical may have other synonyms that do not appear on these lists. 1 i

4 (1) EPCRA Extremely Hazardous Substances (EHSs) The presence of EHSs in quantities at or above the Threshold Planning Quantity (TPQ) requires certain emergency planning activities to be conducted. The extremely hazardous substances and their TPQs are listed in 40 CFR part 355, Appendices A and B. For section 302 EHSs, Local Emergency Planning Committees (LEPCs) must develop emergency response plans and facility owner or operator must notify the State Emergency Response Commission (SERC) or Tribal Emergency Response Commission and their LEPC if a chemical is present at the facility or above the EHS s TPQ. Additionally if the TPQ is equaled or exceeded, facilities with a listed EHS are subject to the reporting requirements of EPCRA section 311 (provide material safety data sheet or a list of covered chemicals to the SERC or TERC, LEPC, and local fire department) and section 312 (submit inventory form -Tier I or Tier II). The minimum threshold for section reporting for EHS substances is 500 pounds or the TPQ, whichever is less. TPQ. The consolidated list presents the TPQ (in pounds) for section 302 chemicals in the column following the CAS number. For chemicals that are solids, there are two TPQs given (e.g., 500/10,000). In these cases, the lower quantity applies for solids in powder form with particle size less than 100 microns, or if the substance is in solution or in molten form. Otherwise, the 10,000 pound TPQ applies. If a solid EHS is in molten form, the facility must multiply the amount of EHS on-site by 0.3 before comparing to the lower listed TPQ. If a solid EHS is in solution form, the facility must multiply amount EHS on-site by 0.2 before comparing to the lower listed TPQ. The reducing factors of 0.2 for molten solids and 0.3 for solids in solution are not to be used for the 12 solid reactive chemicals are noted by footnote a in Appendix A and B in 40 CFR part 355. EHS. Releases of reportable quantities () of EHSs are subject to state and local reporting under section 304 of EPCRA. EPA has adjusted s for EHSs without CERCLA s to levels equal to their TPQs. The EHS column lists these adjusted s for EHSs not listed under CERCLA and the CERCLA s for those EHSs that are CERCLA hazardous substances (see the next section for a discussion of CERCLA s). Note that ammonium hydroxide is not covered under section 302; the EHS is based on anhydrous ammonia. Ammonium hydroxide (which is also known as aqueous ammonia) is subject to CERCLA, with its own. (2) CERCLA Hazardous Substances Releases of CERCLA hazardous substances, in quantities equal to or greater than their reportable quantity (), are subject to reporting to the National Response Center under CERCLA. Notification requirements for these releases are found in 40 CFR 302. Such releases are also subject to state and local reporting under section 304 of EPCRA. CERCLA hazardous substances, and their reportable quantities, are listed in 40 CFR part 302, Table Radionuclides listed under CERCLA are provided in a separate list in Appendix B of this document, with s in Curies. Chemical categories under CERCLA (including metal compound categories), which have N.A. listed for the CAS Number in the consolidated table, ii

5 are also listed in Appendix E of this document with further explanation of each chemical category, where information was available.. The CERCLA column in the consolidated list shows the s (in pounds) for chemicals that are CERCLA hazardous substances. Metals. For metals listed under CERCLA (antimony, arsenic, beryllium, cadmium, chromium, copper, lead, nickel, selenium, silver, thallium, and zinc), no reporting of releases of the solid form is required if the mean diameter of the pieces of the solid metal released is greater than 100 micrometers (0.004 inches) (Ref: Footnote after Table in 40 CFR 302.4). The s shown on the consolidated list apply to smaller particles. Note that the consolidated list does not include all CERCLA regulatory synonyms. See 40 CFR part 302, Table for a complete list. (3) Section List of Substances for Accidental Release Prevention Under the accident prevention provisions of section of the, EPA developed a list of 77 toxic substances and 63 flammable substances. Threshold quantities (s) were established for these substances. The list and s identify processes subject to accident prevention regulations. The list of substances and s and the requirements for risk management programs for accidental release prevention are found in 40 CFR part 68. This consolidated list includes both the common name for each listed chemical under section and the chemical name, if different from the common name, as separate listings. The section list includes several substances in solution that are covered only in concentrations above a specified level. These substances include ammonia (concentration 20% or greater) (CAS number ); hydrochloric acid (37% or greater) ( ); hydrogen fluoride/hydrofluoric acid (50% or greater) ( ); and nitric acid (80% or greater) ( ). Hydrogen chloride (anhydrous) and ammonia (anhydrous) are listed, in addition to the solutions of these substances, with different s. Only the anhydrous form of sulfur dioxide ( ) is covered. These substances are presented on the consolidated list with the concentration limit or specified form (e.g., anhydrous), as they are listed under section. Flammable fuels used as a fuel or held for sale as a fuel at a retail facility are not subject to the rule.. The section column in the consolidated list shows the s (in pounds) for chemicals listed for accidental release prevention. The applies to the quantity of substance in a process, not at the facility as a whole. (4) EPCRA Section 313 Toxic Chemicals (a.k.a Toxics Release Inventory (TRI) Chemicals) Emissions, transfers, and waste management data for chemicals listed under section 313 must be reported annually as part of the community right-to-know provisions of EPCRA (40 CFR part 372). These reports are also known as Toxics Release Inventory (TRI) reports. iii

6 Section 313. The notation 313 in the column for section 313 indicates that the chemical is subject to reporting under section 313 and section 6607 of the Pollution Prevention Act under the name listed. In cases where a chemical is listed under section 313 with a second name in parentheses or brackets, the second name is included on this consolidated list with an X in the section 313 column. An X in this column also may indicate that the same chemical with the same CAS number appears on another list with a different chemical name. Diisocyanates, Dioxins and Dioxin-like Compounds, and PACs. In the November 30, 1994, expansion of the section 313 list, 20 specific chemicals were added as members of the diisocyanate category, and 19 specific chemicals were added as members of the polycyclic aromatic compounds (PAC) category. The PAC category was expanded to 25 total chemicals by additions made in October 1999 and November In October 1999, EPA added a category of dioxin and dioxin-like compounds that includes 17 specific chemicals. These chemicals are included in the CAS order listing on this consolidated list, although chemicals belonging to these categories are reportable under section 313 by category, rather than by individual chemical name. The symbol # following the 313 notation in the section 313 column identifies diisocyanates, the symbol! identifies the dioxin and dioxinlike compounds, and the symbol + identifies PACs, as noted in the Summary of. Ammonium Salts. The EPCRA section listing for ammonia includes the following qualifier includes anhydrous ammonia and aqueous ammonia from water dissociable ammonium salts and other sources; 10 percent of total aqueous ammonia is reportable under this listing. The qualifier for ammonia means that anhydrous forms of ammonia are 100% reportable and aqueous forms are limited to 10% of total aqueous ammonia. Therefore, when determining threshold and releases and other waste management quantities all anhydrous ammonia is included but only 10% of total aqueous ammonia is included. Any evaporation of ammonia from aqueous ammonia solutions is considered anhydrous ammonia and should be included in threshold determinations and release and other waste management calculations. In this document ammonium salts are not specifically identified as being reportable EPCRA section 313 chemicals. However, water dissociable ammonia salts, such as ammonium chloride, are reportable if they are placed in water. When ammonium salts are placed in water, reportable aqueous ammonia is manufactured. As indicated in the ammonia qualifier, all aqueous ammonia solutions from water dissociable ammonium salts are covered by the ammonia listing. For example, ammonium chloride is a water-dissociable ammonium salt and reportable aqueous ammonia will be manufactured when it is placed in water. Unlike other ammonium salts, ammonium hydroxide is specifically identified as being a reportable EPCRA section 313 chemical. This is because the chemical ammonium hydroxide (NH4OH) is a misnomer. It is a common name used to describe a solution of ammonia in water (i.e., aqueous ammonia), typically a concentrated solution of 28 to 30 percent ammonia. EPA has consistently responded to questions regarding the reportability of these purported ammonium hydroxide solutions under the EPCRA section 313 ammonia listing by stating that these are 28 to 30 percent solutions of ammonia in water and that the solutions are reportable under the EPCRA section 313 ammonia listing. For a more detailed discussion, see page of the Federal Register final rule of June 30, 1995 (60 FR 34172). (See also EPA s EPCRA iv

7 section 313, Guidance for Reporting Aqueous Ammonia, EPA 745-R00-005, Stayed TRI Chemicals. There are two EPRCA section 313 chemicals that are listed in the CFR but for which the Agency has issued an administrative stay that excludes them from reporting until the stays are lifted. These chemicals, identified by 313s in the Sec. 313 table column, are methyl mercaptan (CAS number ), and 2,2-dibromo-3nitrilopropionamide (CAS number ). Check the TRI Web site for updated regulatory information. On October 11, 2011, EPA reinstated the TRI reporting requirements for hydrogen sulfide. This action will be effective for the 2012 TRI reporting year, with the first 2012 TRI reports due from facilities by July 1, For more information, see TRI Reporting Thresholds. Reporting under EPCRA section 313 is triggered by the quantity of a chemical that is manufactured, processed, or otherwise used during the calendar year. For most TRI chemicals, the thresholds are 25,000 pounds manufactured or processed or 10,000 pound otherwise used. Sixteen TRI chemicals and four TRI chemical categories that meet the criteria for persistence and bioaccumulation have lower thresholds, such as 10 or 100 pounds and 0.1 grams. These 20 chemical listings and their reporting thresholds can be found at (5) Chemical Categories The CERCLA and EPCRA section 313 lists include a number of chemical categories as well as specific chemicals. Categories appear on this consolidated list at the beginning of the CAS number order listing. The specific chemicals or substances that are included in the CERCLA category Radionuclides can be found in Appendix B. Appendix D contains explanations and definitions for the EPCRA section 313 (TRI) chemical categories. For the CERCLA listed categories reported with CAS number of N.A., Appendix E contains information available on the CERCLA chemical categories from their original statutory and regulatory sources. Specific chemicals listed as members of the diisocyanates, dioxin and dioxin-like compounds, and PAC categories under EPCRA section 313 are included in the list of specific chemicals by CAS number, not in the category listing. EPA has attempted to identify those chemicals on the consolidated list that are clearly reportable under one or more of the EPCRA section 313 (TRI) chemical categories. For example, mercuric acetate (CAS number ), listed under section 302, is not specifically listed under section 313, but is reportable under the section 313 Mercury Compounds category (no CAS number). Listed chemicals that have been identified as being reportable under one or more EPCRA section 313 categories are identified by 313c in the Sec. 313 table column. The chemicals on the consolidated list have not been systematically evaluated to determine whether they fall into any of the CERCLA listed categories. Some chemicals not specifically listed under CERCLA may be subject to CERCLA reporting as part of a category. For v

8 example, strychnine sulfate (CAS number ), listed under EPCRA section 302, is not individually listed on the CERCLA list, but is subject to CERCLA reporting under the listing for strychnine and salts (CAS number ), with an of 10 pounds. Similarly, nicotine sulfate (CAS number ) is subject to CERCLA reporting under the listing for nicotine and salts (CAS number , 100 pounds), and warfarin sodium (CAS number ) is subject to CERCLA reporting under the listing for warfarin and salts, concentration >0.3% (CAS number , 100 pounds). Note that some CERCLA listings, although they include CAS numbers, are for general categories and are not restricted to the specific CAS number (e.g., warfarin and salts). The CERCLA list also includes a number of generic categories that have not been assigned s; chemicals falling into these categories are considered CERCLA hazardous substances, but they are not required to be reported under CERCLA unless otherwise listed under CERCLA with an. (6) RCRA Hazardous Wastes The consolidated list includes specific chemicals from the RCRA P and U lists only (40 CFR ). This listing is provided as an indicator that companies may already have data on a specific chemical that may be useful for EPCRA reporting. It is not intended to be a comprehensive list of RCRA P and U chemicals. RCRA hazardous wastes consisting of waste streams on the F and K lists, and wastes exhibiting the characteristics of ignitability, corrosivity, reactivity, and toxicity, are provided in Appendix C in this document. This list also includes K181 hazardous waste with a statutory one-pound (indicated by an asterisk * following the. The descriptions of the F and K waste streams have been abbreviated; see 40 CFR part 302, Table 302.4, or 40 CFR part 261 for complete descriptions. RCRA Code. The letter-and-digit code in the RCRA Code column is the chemical's RCRA hazardous waste code. in Section 313 column Summary of + Member of EPCRA Section 313 PAC category. # Member of EPCRA Section 313 diisocyanate category. c Although not listed by name and CAS number, this chemical is reportable under one or more of the EPCRA section 313 chemical categories. s Indicates that this chemical is currently under an administrative stay of the EPCRA section 313 reporting requirements, therefore, no Toxics Release Inventory reports are required until the stay is removed.! Member of the EPCRA section 313 dioxin and dioxin-like compounds category. X Indicates that this is a second name for an EPCRA section 313 chemical already included on this consolidated list. May also indicate that the same chemical with the same CAS number appears on another list with a different chemical name. vi

9 in CERCLA column * The Agency may adjust the statutory for this RCRA hazardous substance (K181 waste) in a future rulemaking; until then the statutory one-pound applies. PMN This EHS chemical was identified from a Premanufacture Review Notice (PMN) submitted to EPA. The submitter has claimed certain information on the submission to be confidential, including specific chemical identity. & Indicates that no is assigned to this generic or broad class, although the class is a CERCLA hazardous substance. See 50 Federal Register (April 4, Releases in amounts less than 1,000 pounds per 24 hours of nitrogen oxide or nitrogen dioxide to the air that are the result of combustion and combustion related activities are exempt from the notification requirements of EPCRA section 304 and CERCLA. vii
