United States Office of Environmental Revised December 2000 Environmental Protection Information EPA 745-R-00-004 Agency Washington, DC 20460 TOXICS RELEASE INVENTORY List of Toxic Chemicals within the Glycol Category

Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) requires certain facilities manufacturing, processing, or otherwise using listed toxic chemicals to report their environmental releases of such chemicals annually. Beginning with the 1991 reporting year, such facilities also must report pollution prevention and recycling data for such chemicals, pursuant to section 6607 of the Pollution Prevention Act, 42 U.S.C. 13106. When enacted, EPCRA section 313 established an initial list of toxic chemicals that was comprised of more than 300 chemicals and 20 chemical categories. EPCRA section 313(d) authorizes EPA to add chemicals to or delete chemicals from the list, and sets forth criteria for these actions.

This document is an updated version of the previous document, EPA 745-R-99-006, June 1999. This version has the following updates:

• The titles to Table 1 on page 6, Table 2 on page 185, and Table 3 on 187 are modified; and • The CAS number of second listing in Table 3 (Poly(oxy-1,2-ethanediyl), .alpha.- (phenylsulfonyl)-.omega.-methoxy-) on page 187 is changed from 7664-41-7 to 67584-43-4.

2 Section 1. Introduction

On June 28, 1994, EPA promulgated a final rule (published in the Federal Register July 5, 1994) modifying the definition of the glycol ethers category on the list of toxic chemicals under Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA), 42 U.S.C. 11001 et.seq. The effect of this modification, which is described at 59 FR 34386, is that many high molecular weight glycol ethers were excluded from the category. As described in the final rule, this modification was made retroactive for the 1993 reporting year for reports due July 1, 1994. This modification is also effective for all subsequent reporting years. As part of this modification and as the result of public comment, EPA changed the category name at 40 CFR 372.65(c) from 'glycol ethers' to 'certain glycol ethers'. However, this document will refer to the constituents of this category simply as glycol ethers. At the time of the modification, EPA indicated that the Agency would work with the public and the regulated community to develop, as appropriate, interpretations and guidance that the Agency determines are necessary to facilitate accurate reporting for the modified glycol ethers category. This document constitutes such guidance.

Who Must Report

A plant, factory, or other facility is subject to the provisions of EPCRA section 313, if it meets all three of the following criteria:

C It is included in Standard Industrial Classification (SIC) codes 10 (except 1011, 1081, and 1094); 12 (except 1241); 20 through 39; 4911 (limited to facilities that combust coal and/or oil for the purpose of generating power for distribution in commerce);, 4931 (limited to facilities that combust coal and/or oil for the purpose of generating power for distribution in commerce); 4939 (limited to facilities that combust coal and/or oil for the purpose of generating power for distribution in commerce); 4953 (limited to facilities regulated under the Resource Conservation and Recovery Act, subtitle C, 42 U.S.C. section 6921 et seq.); 5169; 5171; and 7389 (limited to facilities primarily engaged in recovery services on a contract or fee basis); or is a federal facility; and

C It has 10 or more full-time employees (or the equivalent 20,000 hours per year); and

C It manufactures, imports, processes, or otherwise uses any of the toxic chemicals listed on the EPCRA section 313 list in amounts greater than the "threshold" quantities specified below.

3 Thresholds

Thresholds are specified amounts of toxic chemicals manufactured, processed, or otherwise used during the calendar year that trigger reporting requirements.

If a facility manufactures or imports any of the listed toxic chemicals, the threshold quantity will be:

C 25,000 pounds per toxic chemical or category over the calendar year.

If a facility processes any of the listed toxic chemicals, the threshold quantity will be:

C 25,000 pounds per toxic chemical or category over the calendar year.

If a facility otherwise uses any of the listed toxic chemicals, the threshold quantity is:

C 10,000 pounds per toxic chemical or category over the calendar year.

EPCRA section 313 requires threshold determinations for chemical categories to be based on the total of all chemicals in the category manufactured, processed, or otherwise used. For example, a facility that manufactures three members of a chemical category would count the total amount of all three chemicals manufactured towards the manufacturing threshold for that category. When filing reports for chemical categories, the releases are determined in the same manner as the thresholds. One report is filed for the category and all releases are reported on this form.

Glycol Ethers Category Definition

The glycol ethers category is defined by the following formula:

R - (OCH2CH2)n - OR' where: n = 1, 2, or 3; R = Alkyl C7 or less, or phenyl or alkyl substituted phenyl; R' = H or alkyl C7 or less, or OR' consisting of a ester, sulfate, phosphate, , or sulfonate.

Chemicals that meet this category definition are reportable.

4 EPA is providing three lists of CAS numbers and chemical names to aid the regulated community in determining whether they need to report for the glycol ethers category. Section 2 (pages 5 to 159) lists individual chemicals that meet the definition of the EPCRA section 313 'certain glycol ethers' category. This list consists only of chemicals that have been assigned CAS numbers and, thus, is not exhaustive. If a facility manufactures, processes, or otherwise uses, in greater than threshold quantities, a glycol ether that meets the category definition, whether or not that chemical is on this list, they must report the chemical.

Section 3 (pages 160 to 161) lists chemical mixtures which contain glycol ethers that meet the definition of the EPCRA section 313 'certain glycol ethers' category. EPA has tried to make this list as complete as possible; however, not all mixtures that contain reportable glycol ethers will necessarily appear on this list. If a facility manufactures, processes, or otherwise uses a mixture which includes components, in greater than threshold quantities, that meet the definition of the EPCRA section 313 'certain glycol ethers' category, they must report the glycol ether component(s) that meet the category definition.

Section 4 (pages 162 to 180) lists oligomeric and polymeric chemicals (for the category formula, R - (OCH2CH2)n - OR', n is unspecified) that might contain a glycol ether component (n = 1, 2, or 3). EPA has tried to make this list as complete as possible; however, not all oligomeric or polymeric chemicals that might contain glycol ethers will necessarily appear on this list. If a facility manufactures, processes, or otherwise uses an oligomeric or polymeric chemical that contains components, in greater than threshold quantities, that meet the definition of the EPCRA section 313 'certain glycol ethers' category, they must report the glycol ether component(s) that meet the category definition.

Ethylene Glycol Ethers versus Ethers

The members of this category are glycol ethers derived from glycol, , and . This category does not contain glycol ethers based on propylene glycol, dipropylene glycol, or tripropylene glycol.

Individually Listed Glycol Ethers

There are two chemicals, 2-methoxyethanol (CAS number 109-86-4) and 2-ethoxyethanol (CAS number 110-80-5) that are on the individual chemical list and CAS number list (40 CFR 372.65(a) and (b)). Threshold determinations should be made for each of these chemicals individually and separately from the glycol ethers category.

De Minimis Concentrations The glycol ethers category is subject to the one percent de minimis concentration. Thus, mixtures that contain members of this category at concentrations in excess of one percent should be factored into threshold and release determinations.

5 Section 2. CAS Number List of Some Chemicals within the Glycol Ethers Category

EPA is providing the following list of CAS numbers and chemical names to aid the regulated community in determining whether they need to report for the glycol ethers category. The following list consists of individual chemicals that meet the definition of the EPCRA section 313 'certain glycol ethers' category. This list consists only of those chemicals that have been assigned CAS numbers and, thus, is not exhaustive. If a facility manufactures, processes, or otherwise uses, in greater than threshold quantities, a glycol ether that meets the category definition, whether or not that chemical is on this list, they must report the chemical.
