Glycol Ethers Category; Toxic Chemical Release Reporting; 
Community Right-to-Know

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is redefining the glycol ethers category list of toxic 
chemicals subject to reporting under section 313 of the Emergency 
Planning and Community Right-to-Know Act of 1986 (EPCRA). EPA is 
changing the present definition of the glycol ethers category to 
exclude the high molecular weight glycol ethers that do not, in EPA's 
judgement, meet the criteria set out in EPCRA section 313(d). This 
redefinition of the glycol ethers category, which is based on EPA's 
review of available human health data on short-chain length glycol 
ethers, eliminates the EPCRA section 313 reporting requirements for 
those glycol ethers known as surfactant glycol ethers.

EFFECTIVE DATE: This rule is effective June 28, 1994.

SUPPLEMENTARY INFORMATION:

I. Introduction

A. Statutory Authority

    This action is issued under section 313(d) of the Emergency 
Planning and Community Right-to-Know Act of 1986 (42 U.S.C. 11023, 
``EPCRA''). EPCRA is also referred to as Title III of the Superfund 
Amendments and Reauthorization Act (SARA) of 1986.

B. Background

    Section 313 of EPCRA requires certain facilities manufacturing, 
processing, or otherwise using 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). Section 313 
established an initial list of toxic chemicals that was comprised of 
more than 300 chemicals and 20 chemical categories. Section 313(d) 
authorizes EPA to add chemicals to or delete chemicals from the list, 
and sets forth criteria for these actions. Under section 313(e), any 
person may petition EPA to add chemicals to or delete chemicals from 
the list. EPA has added to and deleted chemicals from the original 
statutory list.
    EPA issued a statement of petition policy and guidance in the 
Federal Register of February 4, 1987 (52 FR 3479), to provide guidance 
regarding the recommended content and format for petitions. On May 23, 
1991 (56 FR 23703), EPA published guidance regarding the recommended 
content of petitions to delete individual members of the section 313 
metal compound categories.

II. Effective Date

    This action becomes effective immediately. Thus, the last year in 
which facilities had to report releases of high molecular weight glycol 
ethers now excluded from the list was 1993, covering releases that 
occurred in 1992. The effect of this category redefinition is that, 
since the high molecular weight glycol ethers being excluded from the 
category will not be on the section 313 list when facilities report in 
1994 for releases that occurred in 1993, these reports and all 
subsequent reports need not include release data for these glycol 
ethers. Facilities will therefore not have to collect release 
information for any releases of the excluded glycol ethers that 
occurred during the 1993 reporting year or for any releases that occur 
in the future.
    Section 313(d)(4) provides that ``[a]ny revision [to the section 
313 list] made on or after January 1 and before December 1 of any 
calendar year shall take effect beginning with the next calendar year. 
Any revision made on or after December 1 and before January 1 shall 
take effect beginning with the calendar year following the next 
calendar year.'' The Agency interprets this delayed effective date 
provision to apply only to actions that add chemicals to the section 
313 list. For deletions, the Agency may, in its discretion, make such 
actions immediately effective. An immediate effective date is 
authorized, in these circumstances, under 5 U.S.C. section 553(d)(1) 
since a deletion from the section 313 list relieves a regulatory 
restriction.
    The Agency believes that the purpose behind the section 313(d)(4) 
effective date provision is to allow facilities adequate planning time 
to incorporate newly added chemicals to their Toxic Release Inventory 
(TRI) release data collection processes. A facility would not need 
additional planning time to not report releases of a given chemical. 
Thus, a reasonable construction of section 313(d)(4), given the overall 
purpose and structure of EPCRA -- to provide the public with 
information about chemicals which meet the criteria for inclusion on 
the section 313 list -- is to apply the delayed effective date 
requirement only to additions to the list. Where the Agency has 
determined, as it has with the excluded glycol ethers, that a chemical 
does not satisfy the criteria of section 313(d)(2)(A)-(C), no purpose 
is served by requiring facilities to collect release data or file 
release reports for that chemical, or, therefore, by leaving that 
chemical on the section 313 list for any additional period of time. 
Nothing in the legislative history suggests that section 313(d)(4) was 
intended to apply to deletions as well as additions; indeed, such a 
construction would be incongruous, since deleted chemicals, by 
definition, do not satisfy the criteria for being on the section 313 
list and their deletion from that list should not be delayed in the 
absence of any compelling reason to the contrary. This construction of 
section 313(d)(4) is also consistent with previous rules deleting 
chemicals from the section 313 list. Indeed, the Agency has not given 
any of its rules deleting chemicals from the section 313 list the 
delayed effective dates specified in section 313(d)(4).
    EPA has not deleted all glycol ethers from reporting requirements 
under EPCRA section 313. Reporting will still be required for those 
glycol ethers which meet the revised definition.

III. Description of the EPCRA Section 313 Glycol Ethers Category

    In the Federal Register of July 6, 1993 (58 FR 36180), EPA issued a 
proposed rule to redefine the glycol ethers category on the EPCRA 
section 313 list of toxic chemicals. EPA has evaluated the current 
scope of the section 313 glycol ethers category and believes that it is 
overly broad. The existing category includes substances that 
traditionally have not been considered glycol ethers. Also, it is 
apparent that this category contains members that do not meet the EPCRA 
section 313(d)(2) criteria for listing. EPA has reviewed the current 
glycol ethers category and is redefining it to exclude the surfactant 
glycol ethers. Surfactant glycol ethers are those glycol ethers with 
pendant alkyl groups which typically consist of eight or more carbon 
atoms (i.e., high molecular weight glycol ethers). However, EPA does 
not believe that the category can be more narrowly defined at this 
time.
    EPA's revised glycol ethers category for which section 313 
reporting is required, consists of those glycol ethers which meet the 
following definition:

Certain Glycol Ethers:
    R - (OCH2CH2)n - OR'
Where:
    n = 1, 2, or 3;
    R = alkyl C7 or less, or
    R = phenyl or alkyl substituted phenyl;
    R' = H or alkyl C7 or less; or
    OR' consisting of carboxylic acid ester, sulfate, phosphate, 
nitrate, or sulfonate.

IV. Rationale for Redefinition

    EPA's concerns for the included chemicals is based on a review of 
available human health data on short-chain length glycol ethers. 
Specifically, EPA believes that these chemicals meet the criterion of 
EPCRA section 313(d)(2)(B) because the individual members of this 
category can be reasonably anticipated to cause one or more of the 
following effects: Kidney toxicity, liver toxicity, adverse blood 
effects, adverse central nervous system effects, reproductive effects, 
and developmental effects. EPA believes that the category can be 
redefined to exclude those glycol ethers known as surfactant glycol 
ethers because these high molecular weight glycol ethers do not meet 
the listing criteria in section 313(d)(2)(A) or (B). None of the 
chemicals in the current glycol ethers category meet the toxicity 
criterion of section 313(d)(2)(C) based on their ecotoxicity. EPA's 
rationale for this redefinition is detailed in the proposed rule and is 
based on the Agency's review of various relevant materials.

V. Response to Comments

    EPA received 11 comments on the proposed rule, all in support of 
the proposed redefinition of the glycol ethers category. However, 
several of the commenters expressed the opinion that the proposed rule 
does not narrow the definition sufficiently, and that EPA should 
consider a further narrowing of the definition in the future. As 
discussed below, EPA does not believe that it currently has sufficient 
data to further narrow the category definition.
    Two commenters, the Chemical Manufacturers Association (CMA), 
Propylene Glycol Ethers Panel, and CMA Ethylene Glycol Ethers Panel, 
stated that the name of the category should be changed to ``certain 
glycol ethers'' to more accurately characterize the chemicals that are 
within the category. EPA has incorporated this comment, since this 
category does not consist of all chemicals that contain the glycol 
ether functionality.
    One commenter, General Electric, suggested that the definition 
should not identify reportable glycol ethers by molecular structure. 
Instead, the commenter recommended listing the glycol ethers of concern 
individually, and identifying those which must be reported on an 
individual basis. All remaining glycol ethers would then be reported in 
an aggregate form. EPA believes this approach to defining the category 
is inappropriate and unnecessary. EPA has identified by molecular 
formula a specific group of glycol ethers having a common structure 
that pose similar hazards. EPA currently believes that the most 
appropriate way to report on this group of glycol ethers is in 
aggregate by category. A listing of glycol ethers as proposed by the 
commenter may exclude from reporting certain glycol ethers within the 
scope of the definition in this rulemaking that meet the section 
313(d)(2) criterion. Therefore, EPA is adopting the redefinition of the 
glycol ethers category based on a molecular structure formula. A 
reporting facility must make aggregate reporting threshold and 
estimated release determinations for all glycol ethers in the category.
    The Soap and Detergent Association proposed that the revised 
definition exclude sulfonate in the category of OR' because ``carbon 
sulfur bonds are not easily broken and, therefore, sulfonates are not 
readily hydrolyzable from surfactants.'' EPA proposed the inclusion of 
sulfonate not because of the possible reaction at the carbon sulfur 
bond in the sulfonate, e.g., desulfonation of aromatic sulfonates, but 
rather because the sulfonate ion is a reactive leaving group and thus 
can reasonably be anticipated to be hydrolyzed to yield a glycol ether 
of concern. Specifically hydrolysis of R-
(OCH2CH2)nOSO2R'' (where R'' is any organic 
substituent) yields R-(OCH2CH2)nOH and R''SO2OH. 
Therefore, EPA reaffirms its inclusion of sulfonate as an appropriate 
member in the category of OR'.
    The Chemical Manufacturers Association stated that the category 
should be limited to four specific ethylene glycol ether solvents: 2-
Methoxyethanol, 2-ethoxyethanol, and their acetates. As stated in the 
proposed rule, with respect to the glycol ethers and developmental 
effects, there is evidence that the toxicity is reduced going from the 
methyl to the butyl ether. However, data for other toxic effects on 
glycol ethers with pendant alkyl groups of one to seven carbons or a 
phenyl group do not indicate a trend towards increased toxicity based 
on chain length for other toxic effects. Low molecular weight ethylene 
glycol ethers disturb the hemopoiesis and the blood picture at low 
doses. Hemolysis has been reported in varying degrees for ethylene 
glycol ethers of one to five carbons in the alkyl chain. The optimum 
alkyl chain length for hemolysis is four carbons. 2-Phenoxyethanol has 
also been found to cause intravascular hemolysis. Therefore, the 
concerns for ethylene glycol ethers are not limited to the four 
specific compounds mentioned by the commenter.
    In the proposed rule, EPA requested comment on whether the 
definition of R' should include only straight chained alkyl groups of 
seven of fewer carbons or both straight and branched alkyl groups of 
seven or fewer carbons. No comments on this issue were received. 
Therefore, the definition of R' will include both straight and branched 
alkyl groups of seven or fewer carbons.
    Rochester Midland, Soap and Detergent Association, Henkel 
Corporation, and Union Carbide Corporation asked that the definition 
also exclude alkylated phenols containing seven or more carbon atoms. 
As stated in the proposed rule, 2-phenoxyethanol is known to cause 
hemolysis. No data have been found for alkyl substituted phenoxyethanol 
derivatives. Henkel Corporation stated that ``[t]he C8, C9, 
and C12 alkyl phenol ethoxylates have also been used for many 
years as surfactants. There is no evidence that they present adverse 
human effects such as those which caused the listing of the glycol 
ether category or would otherwise meet the section 313 criteria.'' 
However, this commenter did not supply data to substantiate this 
assertion. The Soap and Detergent Corporation provided two studies to 
support its position (Smyth and Calandra, 1969; Dudek and Ribelin, 
1988). Neither of these studies specifies the composition of the test 
material by number of ethylene oxide units. The commenter did provide 
the typical weight percent of the test substances as sold in commerce. 
Even if EPA assumed these typical compositions represent the test 
materials of these two studies, the dose levels presented in the 
studies would not be considered adequate to establish the lack of 
toxicity associated with ethylene glycol ethers with alkyl groups 
consisting of seven or greater carbon atoms.
    Because only phenoxyethanol has been tested for systemic toxicity, 
change in the glycol ethers category definition which would exclude 
alkylphenol ethoxylates is not supportable, based on the available 
data. To evaluate the alkylphenol ethoxylates subcategory of the 
ethylene glycol ether category, EPA would require subchronic toxicity 
data for one or more specific members of the category (e.g., 2-
nonylphenoxyethanol). In the absence of these data, the Agency believes 
that the glycol ethers category should continue to include these 
substances.
    General Electric contended that individual glycol ethers should be 
listed in lieu of a category because EPCRA section 313 ``clearly states 
that additions to the EPCRA section 313 list must be done on a 
chemical-by-chemical basis. Each statutory provision that deals with 
revising the section 313 list speaks only in terms of a chemical-by-
chemical basis, and EPCRA is silent on the issue of regulating by 
chemical categories.'' The Agency believes that the statutory authority 
to add ``a chemical'' to the list may be reasonably interpreted to 
include the authority to add groups or categories of chemicals to the 
list, particularly in light of the fact that the original list adopted 
by Congress in section 313(c) of EPCRA included 20 chemical categories. 
These consist mostly of metal compounds categories, but also include 
categories of organic chemicals, such as glycol ethers (as noted in the 
proposed rule, Congress listed this category without a delimiting 
definition).
    General Electric further contended that Congress listed ``glycol 
ethers'' in addition to the two individually listed glycol ethers, ``2-
methoxyethanol'' and ``2-ethoxyethanol,'' to allow facilities the 
option of aggregating the releases of the two individually listed 
glycol ether chemicals and filing one TRI Form R report for ``glycol 
ether'' rather than two separate Form R reports. EPA does not accept 
this interpretation of Congress' intent in listing 20 chemical 
categories on the original EPCRA section 313(c) list of chemicals 
subject to TRI reporting. There is no clear statement of Congressional 
intent to adopt the type of ``optional'' reporting scheme advocated by 
General Electric. Indeed, the legislative history cited by General 
Electric supports EPA's current interpretation and implementation of 
EPCRA's reporting structure, i.e., persons manufacturing, processing, 
or otherwise using more than one member of a chemical category above 
the applicable reporting threshold may report the releases of all such 
chemicals, in the aggregate, on a single Form R report, rather than 
listing data separately for each chemical in the group.
    Furthermore, contrary to General Electric's contention, several of 
the original chemical categories did not have corresponding 
``individual'' chemicals listed on the original (CAS number specific) 
section 313(c) list. In their comments, General Electric acknowledged 
this to be the case only with regard to the polybrominated biphenyls 
(PBBs) category. However, there was no individual listing for any 
barium compounds, cadmium compounds, chromium compounds, or several 
other metal compounds in the original list transmitted to EPA by 
Congress. See 53 FR 4500; February 16, 1988. Taken to its logical 
conclusion, General Electric's interpretation would result in no 
reporting of any members of the PBBs category unless and until EPA 
listed individual members of that category. EPA does not believe that 
this would be consistent with Congress' intent in listing this category 
on the initial section 313(c) list. If Congress had intended to include 
category listings as an optional method of reporting individually 
listed chemicals, it could have clearly stated so in the statute. At a 
minimum, some members of all the listed chemical categories would have 
been included in the CAS number specific list. In sum, EPA believes 
that its interpretation of the category reporting structure is a 
reasonable reading of EPCRA.
    General Electric objected to the continued listing of a glycol 
ethers category because categories are difficult for EPA to administer 
and/or for the public and industry to understand. In addition, the 
commenter contended that industry compliance with reporting and 
supplier notification requirements is more difficult for categories, 
such as glycol ethers, because facilities are not provided with 
discrete chemical names and Chemical Abstract Service (CAS) registry 
numbers. The commenter contended that these problems are magnified in 
the case of the glycol ethers category because the category is defined 
by molecular structure formula.
    Since the glycol ethers category consists of chemicals that are 
similar chemically and in potential effect, EPA believes that this 
category will not be difficult for the public or industry to understand 
or for the Agency to administer. The Agency will work with the public 
and the regulated community to develop, as appropriate, any 
interpretations and guidance the Agency determines are necessary to 
facilitate accurate reporting for the ``certain glycol ethers'' 
category. The Agency does not believe that the glycol ethers category 
is unique in that it is defined by molecular structure formula. All of 
the metal compound categories are defined based on molecular structure 
formula, i.e., to be considered a member of a metal compound category, 
the compound must consist of the parent metal and at least one 
substituent group. Both the chlorophenols and cyanide compound 
categories are defined by molecular structure formulas on the EPCRA 
section 313 list. EPA believes that defining the category by molecular 
structure formula ensures that all members of the category that meet 
the EPCRA section 313(d)(2) criteria are included and thus reportable.
    Three commenters, the Soap and Detergent Association, Proctor and 
Gamble Co., and Union Carbide contended that EPA should be consistent 
between EPCRA and TSCA on its treatment of identical materials. Union 
Carbide cited the TSCA section 8(b) Inventory provisions. EPA believes 
that the differing treatment of glycol ether species with a low degree 
of ethoxylation under EPCRA and TSCA is appropriate given the differing 
purposes and standards of TSCA section 8(b) and EPCRA section 313. TSCA 
is concerned with the regulation of unreasonable risks to human health 
and the environment posed by chemical substances and mixtures in 
commerce; the section 8(b) Inventory, with few exceptions, provides a 
list of those chemical substances and mixtures. For purposes of 
developing an inventory of chemical substances in commerce, it is less 
important to specify whether those substances consist of a discrete 
species, e.g., chloroform, or a species with a range of molecular 
weights. EPCRA's goal is to provide the general public with a broad 
range of information on releases of certain chemicals.
    Under TSCA, for example, glycol ether surfactant ``mixtures'' are 
considered as a single entity for purposes of entry on the Inventory; 
however, for purposes of reviewing the potential health or 
environmental unreasonable risks posed by activities involving such 
chemical substances, the impacts of their various components would be 
considered. Because the intent of EPCRA section 313 is community right-
to-know, EPA wants to ensure that the public has access to information 
on each listed toxic chemical or chemical category to which the public 
could be exposed, regardless of whether it is in a mixture. Therefore, 
where a surfactant contains species with a low degree of ethoxylation 
that fit the glycol ether category definition, EPA requires that those 
chemicals be reported.
    Union Carbide also contended that ``[a]s a legal matter, the 
current and proposed definitions exclude polymers from the category of 
glycol ethers. Since polymers potentially include their low molecular 
weight species (n = 1, 2, 3), the exemption for polymers precludes the 
need to report low molecular weight species under [s]ection 313.''
    EPA disagrees with Union Carbide's conclusion regarding species 
with low degrees of ethoxylation. The proposed definition being 
finalized today continues to exclude polymer molecules (i.e., those 
molecules which include at least four covalently linked subunits at 
least two of which are internal subunits), and to include low molecular 
weight glycol ethers with a low degree of ethoxylation. The change in 
regulatory text deleting the phrase ``polymers are excluded from this 
category,'' does not change EPA's position regarding the scope of the 
glycol ethers category.
    One commenter, the Cosmetic, Toiletry, and Fragrance Association, 
stated support for the proposal to change the definition of glycol 
ethers on other EPA lists. Today's action is not intended, and should 
not be inferred to affect the definition or regulatory requirements for 
glycol ethers under any statute or EPA program other than the Toxic 
Release Inventory reporting requirements under EPCRA section 313 and 
the Pollution Prevention Act section 6607. Specifically, the 
redefinition of glycol ethers on the EPCRA section 313 list does not in 
any way alter their definition under section 112(b) of the Clean Air 
Act (CAA), 42 U.S.C. section 7412(b) as amended, or, by virtue of their 
status as ``hazardous air pollutants'' (HAP) under the CAA, as 
``hazardous substances'' under section 101(14) of the Comprehensive 
Environmental Response, Compensation and Liability Act (CERCLA), 42 
U.S.C section 9601(14).

 VI. Rulemaking Record

    The record supporting this final rule is contained in the docket 
number OPPTS-400073B. All documents, including an index of the docket, 
are available for viewing and photocopying in the TSCA Nonconfidential 
Information Center (NCIC), also known as the TSCA Public Docket Office, 
from noon to 4 p.m., Monday through Friday, excluding legal holidays. 
The TSCA NCIC is located at EPA Headquarters, Rm. NE-B607, 401 M St., 
SW., Washington, DC 20460.

VII. Regulatory Assessment Requirements

A. Executive Order 12866

    Under Executive Order (E.O.) 12866 (58 FR 51735, October 4, 1993), 
the Agency must determine whether the regulatory action is 
``significant'' and therefore subject to review by the Office of 
Management and Budget (OMB) and the requirements of the Executive 
Order. Section 3(f) of the Order defines a ``significant regulatory 
action'' as an action likely to lead to a rule (1) Having an annual 
effect on the economy of $100 million or more, or adversely and 
materially affecting a sector of the economy, productivity, 
competition, jobs, the environment, public health or safety, or State, 
local or tribal governments or communities (also referred to as 
``economically significant''); (2) creating serious inconsistency or 
otherwise interfering with an action taken or planned by another 
agency; (3) materially altering the budgetary impacts of entitlements, 
grants, user fees, or loan programs; or (4) raising novel legal or 
policy issues arising out of legal mandates, the President's 
priorities, or the principles set forth in this Executive Order.
    Pursuant to the terms of this Executive Order, it has been 
determined that this final rule is not ``significant'' and therefore 
not subject to OMB review.

B. Regulatory Flexibility Act

    The Regulatory Flexibility Act of 1980 requires each Federal agency 
to perform a Regulatory Flexibility Analysis for all rules that are 
likely to have a ``significant impact on a substantial number of small 
entities.''
    40 CFR part 372 exempts certain small businesses (specifically, 
those facilities with fewer than 10 full-time employees) from 
reporting. This exclusion exempts about one-half of all manufacturing 
facilities in Standard Industrial Classification (SIC) codes 20 through 
39 from section 313 reporting. Additionally, facilities which 
manufacture or process less than 25,000 pounds or otherwise use less 
than 10,000 pounds of these chemicals annually are not required to 
report for these chemicals. Thus, many small facilities will not incur 
any regulatory costs in association with this rule. Small businesses 
are not expected to be adversely affected by this rule, since the rule 
would increase the likelihood that they would not be required to report 
glycol ether releases. Therefore, EPA certifies that this rule is not 
likely to significantly impact small entities.

C. Paperwork Reduction Act

    There are no unique reporting requirements associated with this 
final rule because it redefines the glycol ethers category to exclude 
certain high molecular weight glycol ethers from reporting under 
section 313. Reporting of chemicals that are subject to section 313 has 
been approved by OMB under the provisions of the Paperwork Reduction 
Act, 44 U.S.C. 3501 et seq., and has been assigned the OMB control 
number 2070-0093.
    The public reporting burden for section 313 chemicals is estimated 
to average 43 hours per response, including time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. This rule's redefinition will reduce the 
number of responses required, thus reducing overall burden.
