Chemical categories

Does your facility manufacture, process or otherwise use any listed chemical or chemical category ... 

Your company receives a nickel compound (nickel compound is a listed toxic chemical category) as a bulk solid and performs various size-reduction operations (e.g., grinding) before packaging the compound in 50 pound bags. Your company processes the nickel compound. 

A separate worksheet would be completed for each section 313 chemical or chemical category. Chemicals which are listed with specific qualifiers (e.g., solution manufacture) require that the threshold determinations only be based on the amount of the chemical meeting the qualifier. Use of the worksheet is divided into three steps ... 

Step 2 allows you to identify uses of the chemical or chemical category that were included In Step 1 but that are exempt under section 313. Do not include In Step 2 exempt forms of the chemical not included in the calculations in Step 1. For example. If you did not report the freon contained in the building s air conditioners in Step 1, you would not include the amount as exempt in Step 2. Step 2 is intended for use when one form or use of the chemical is exempt while others forms require reporting. Note the type of exemption for future reference. Also identify, if applicable, the fraction or percentage of the chemical present that Is exempt. Add the amounts in each activity to obtain a subtotal for exempted amounts of the chemical or chemical categories at the facility. 

Step 3 involves subtracting the result of Step 2 from the results of Step 1 for each activity. Compare this net sum to the applicable activity threshold. If the threshold is met or exceeded for any of the three activities, your facility must submit a Form R for that chemical or chemical category. This worksheet should be retained In either case, to document your determination for reporting or not reporting. Do not submit this worksheet, or any other calculations, with your Form R report. Retain the worksheet for your records. 

You must submit a report If you exceed any threshold for any listed chemical or chemical category. For example, if vour facility processes 22.000 pounds of a listed chemical and also otherwise uses 16,000 pounds of that same chemical, although you do not exceed the process threshold, you do exceed the othenwise used threshold (10,000 pounds) and you therefore must report. However, in preparing your reports, you must consider all non-exempted activities and all releases of that chemical from your facility, not just the releases from the otherwise use activity. 

De Minimis Limitation. A listed toxic chemical does not have to be considered if it Is present in a mixture at a concentration below a specified de nvnimis level. The de minimis level is 1.0%, or 0.1% if the chemical meets the OSHA carcinogen standard. See Table II for the de minimis value associated with each listed toxic chemical. For mixtures that contain more than one member of a listed chemical category, the de minimis level applies to the aggregate concentration of all such members and not to each individually. EPA included the de minimis exemption In the njle as a burden reducing step, primarily because facilities are not likely to have information on the presence of a chemical in a mixture or trade name product beyond that available in the product s MSDS. The de minimis levels are consistent with OSHA requirements lor development of MSDS information concerning composition. 

Enter the Chemical Abstracts Service (CAS) registry number in Section 1.2 exactly as it appears in Table II, pages 40-48, for the chemical being reported. CAS numbers are cross-referenced with an alphabetical list of chemical names in Table II of these instructions, tf you are reporting one of the chemical categories in Table II (e.g., copper compounds), enter not applicable, NA, In the CAS number space. 

Enter the name of the chemical or chemical category exactly as it appears in Table II. If the chemical name is followed by a synonym in parentheses, report the chemical by the name that directly follows the CAS number (i.e., not the synonym)...

You must estimate, as accurately as possible, the quantity (in pounds) of the chemical or chemical category that is released annually to each environmental medium. Include only the quantity of the toxic chemical contained in the wastestream in this estimate. If the toxic chemical present at your facility was part of a mixture or trade name product, calculate only the releases of the chemical, not the other components of the mixture or trade name product. If you are only able to estimate the releases of the mixture or trade name product as a whole, you must assume that the release of the toxic chemical is... 

Specific toxic chemicals with CAS Number are listed in alphabetical order on this page. A list of the same chemicals m CAS Number order begins on page 44. Covered Chemical Categories are listed beginning on page 48. 

Section 313 requires emissions reporting on the chemical categories listed below, in addition to the specific chemicals listed above. The metal compounds listed below, unless otherwise specified, are defined as including any unique chemical substance that contains the named metal (i.e., antimony, copper, etc.) as part of that chemical s structure. 

Chemical categories are subject to the 1 percent de minimis concentration unless the substance involved meets the definition of an OSHA carcinogen.

Both lead (CAS number 7439-92-1) and lead compounds (a chemical category) are listed substances subject to reporting under section 313. You have decided that if any of the... 

CAS number and the chemical name reported on page three must exactly match the listed section 313 CAS number and chemical name. Chemical categories should not be reported with a CAS number. A generic chemical name should only be provided if you are claiming the section 313 chemical identity as trade secret. Chemical names should be taken directly from the list in this document (see pages 40-48). Mixture names are to be entered in Part III, Section 1.4 if that is the sole identification. Mixture names that include the name (or CAS number) of one or more section 313 chemical(s) are not valid. 

The name of each toxic chemical and the associated Chemical Abstracts Service (CAS) registry number of each chemical if applicable. (CAS numbers are not used for chemical categories, since they can represent several individual chemicals.)... 

For example, if a mixture contains a chemical (i.e., 12 percent zinc oxide) that is a member of a reportable chemical category (i.e., zinc compounds), the notification must include that the mixture contains a zinc compound at 12 percent by weight. Supplying only the weight percent of the parent metal (zinc) does not fulfill the requirement. The customer must be told the weight percent of the entire compound within a listed chemical category present in the mixture. 

De minimis levels for each toxic chemical and chemical category are listed on pages 40-48. 

The purpose of this letter Is to inform you that a product that we sell to you. Furniture Lacquer KX2-1390, contains 20 percent toluene (Chemical Abstracts Service (CAS) number 108-88-3). We are required to notify you of the presence of toluene in the product under section 313 of the Emergency Planning and Community Right-to-Know Act of 1986. This law requires certain manufacturers to report on annual emissions of specified toxic chemicals and chemical categories. 

EPA. 1999g. Chemicals and chemical categories to which this part applies. Code of Federal Regulations. U.S. Environmental Protection Agency. 

Section 313 of the Emergency Plarming and Commimity Right to Know Act (EPCRA) of 1986 was enacted to facilitate emergency planning, to minimize the effects of potential toxic chemical accidents, and to provide the pubhc with information on releases of toxic chemicals in their communities. The crurent fist contains 581 individually listed chemicals and 30 chemical categories.
