RIN 2070-AJ12
2-ethoxyethanol, 2-ethoxyethanol acetate, 2-methoxyethanol, and
2-methoxyethanol acetate; Proposed Significant New Use Rule
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing a significant new use rule (SNUR) under
section 5(a)(2) of the Toxic Substances Control Act (TSCA) which would
require persons to notify EPA at least 90 days before commencing the
manufacture, import, or processing of 2-ethoxyethanol (CAS No. 110-80-
5) (2-EE), 2-ethoxyethanol acetate (CAS No. 111-15-9) (2-EEA), 2-
methoxyethanol (CAS No. 109-86-4) (2-ME), or 2-methoxyethanol acetate
(CAS No. 110-49-6) (2-MEA) for domestic use in a consumer product or
the manufacture or import of 2-MEA at levels greater than 10,000 pounds
per year. EPA believes that this action is necessary because these
chemicals may be hazardous to human health and their use in a consumer
product may result in human exposure. The required notice would provide
EPA with the opportunity to evaluate intended new uses and associated
activities, and if necessary, prohibit or limit those uses and
activities before they occur.

SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this Action Apply to Me?
You may be potentially affected by this action if you manufacture,
import, or process 2-EE (CAS No. 110-80-5), 2-EEA (CAS No. 111-15-9),
2-ME (CAS No. 109-86-4), or 2-MEA (CAS No. 110-49-6) for use in
consumer products or manufacture or import 2-MEA (CAS No. 110-49-6) at
levels greater than 10,000 pounds per year.
Persons who intend to import any chemical substance governed by a
final SNUR are subject to the TSCA section 13 (15 U.S.C. 2612) import
certification requirements, and to the regulations codified at 19 CFR
12.118 through 12.127 and 127.28. Those persons must certify that they
are in compliance with the SNUR requirements (see TSCA section 13 (15
U.S.C. 2612) and 19 CFR 12.118 through 12.127 and 127.28). The EPA
policy in support of import certification appears at 40 CFR part 707,
subpart B. In addition, any persons who export or intend to export a
chemical substance that is the subject of this proposed rule on or
after March 31, 2005 are subject to the export notification provisions
of TSCA section 12(b) (15 U.S.C. 2611(b)) (see 40 CFR 721.20), and must
comply with the
[[Page 9903]]
export notification requirements in 40 CFR part 707, subpart D.
Potentially affected entities may include, but are not limited to:
Manufacturers (defined by statute to include importers)
and processors of 2-EE, 2-EEA, 2-ME, and 2-MEA (NAICS 325 and 324110),
e.g., chemical manufacturing and petroleum refineries.

II. Background
A. What Action is the Agency Taking?
EPA is proposing to designate the manufacture, import, or
processing of 2-EE (CAS No. 110-80-5), 2-EEA (CAS No. 111-15-9), 2-ME
(CAS No. 109-86-4), and 2-MEA (CAS No. 110-49-6) for domestic use in
consumer products as a significant new use, as well as the manufacture
or import of 2-MEA (CAS No. 110-49-6) at levels greater than 10,000
pounds per year. ``Consumer product'' is defined at 40 CFR 721.3 as ``a
chemical substance that is directly, or as part of a mixture, sold or
made available to consumers for their use in or around a permanent or
temporary household or residence, in or around a school, or in
recreation.'' This proposed rule would require persons intending to
manufacture or import 2-MEA at levels greater than 10,000 pounds per
year as well as those intending to manufacture, import, or process 2-
EE, 2-EEA, 2-ME, or 2-MEA for domestic use in a consumer product to
submit a Significant New Use Notice (SNUN) to EPA at least 90 days
before such manufacture, import, or processing.
B. What is the Agency's Authority for Taking this Action?
Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to
determine that a use of a chemical substance is a ``significant new
use.'' EPA must make this determination by rule after considering all
relevant factors, including those listed in TSCA section 5(a)(2). Once
EPA determines that a use of a chemical substance is a significant new
use, and promulgates a SNUR, section 5(a)(1)(B) of TSCA requires
persons to submit a SNUN to EPA at least 90 days before commencement of
manufacture, import, or processing of the chemical substance for that
use.
C. What is the Applicability of the General Regulatory Provisions?
General regulatory provisions for SNURs appear under subpart A of
40 CFR part 721. These provisions describe persons subject to the rule,
recordkeeping requirements, and exemptions to reporting requirements.
Provisions relating to user fees appear at 40 CFR part 700. Persons
subject to the rule, when finalized, would be required to comply with
the same notice requirements and EPA regulatory procedures as
submitters of premanufacture notices (PMNs) under section 5(a)(1)(A) of
TSCA. In particular, these requirements include the information
submission requirements of TSCA section 5(b) and 5(d)(1), the
exemptions authorized by TSCA section 5(h)(1), (2), (3), and (5), and
the regulations at 40 CFR part 720. Receipt of a SNUN by EPA may
trigger regulatory action under TSCA sections 5(e), 5(f), 6, or 7, if
appropriate, to control the activities on which it has received the
SNUN. If EPA does not take action, EPA is required under TSCA section
5(g) to explain in the Federal Register its reasons for not taking
action.
Persons who intend to export a substance identified in a proposed
or final SNUR are subject to the export notification provisions of TSCA
section 12(b). The regulations that interpret TSCA section 12(b) appear
at 40 CFR part 707, subpart D. Persons who intend to import a chemical
substance identified in a final SNUR are subject to the TSCA section 13
import certification requirements, which are codified at 19 CFR
sections 12.118 through 12.127 and section 127.28. Such persons must
certify that they are in compliance with TSCA requirements. The EPA
policy relating to import certification appears at 40 CFR part 707,
subpart B.
III. Summary of this Proposed Rule
A. Why is EPA Taking this Action?
1. Background. On January 24, 1984, EPA published an Advance Notice
of Proposed Rulemaking (ANPRM) (49 FR 2921) which stated that EPA
determined, based on animal studies, that adverse reproductive and
developmental effects are associated with the subject glycol ethers,
i.e., 2-EE,
[[Page 9904]]
2-EEA, 2-ME, and 2-MEA, at concentrations to which humans may be
exposed. (Ref. 1). EPA was considering the regulatory options available
under TSCA section 6 to control any unreasonable risks from these
chemicals. It solicited comments on the appropriateness of imposing a
partial or total ban on these chemicals. EPA had also consulted with
the Occupational Safety and Health Administration (OSHA) and the
Consumer Product Safety Commission (CPSC) on possible actions under
their legal authorities. Later, in October 1984, the Agency concluded
that these chemicals may pose a significant hazard to humans (Ref. 2).
However, by 1986, EPA's investigation of risks to consumers had led the
Agency to conclude that the current information would not support an
unreasonable risk finding for consumer use. This conclusion was based
on the fact that because of wholesale switching to substitute solvents,
EPA had not been able to identify manufacturers who were currently
using these glycol ethers in their consumer products. EPA stated that
it would continue to consult with the CPSC pursuant to section 9(d) of
TSCA to resolve outstanding issues, particularly to clarify whether
these glycol ethers were being used in consumer products (Ref. 3).
Additionally, EPA stated it was satisfied that any risks from the
substitutes were less than those presented by 2-EE, 2-EEA, 2-ME, or 2-
MEA, and that use of substitutes would reduce overall risks to humans
(Ref. 4).
On May 20, 1986 (51 FR 18488), EPA issued a report to OSHA, under
section 9(a) of TSCA, stating that EPA had a reasonable basis to
conclude that the risk of injury to worker health from exposure to 2-
EE, 2-EEA, 2-ME, and 2-MEA during their manufacturing, processing, and
use is unreasonable and that this risk may be prevented or reduced
sufficiently by OSHA regulatory action (Ref. 3).
2. Initial regulatory response by OSHA. OSHA published its response
on December 11, 1986 (51 FR 44699), stating that it had preliminarily
concluded that occupational exposures to 2-EE, 2-EEA, 2-ME, and 2-MEA
at the current OSHA permissible exposure limits (PELs) may present
significant risks to the health of workers (Ref. 5). On April 2, 1987
(52 FR 10586), OSHA published an ANPRM under section 6(b) of the
Occupational Safety and Health Act of 1970 (29 U.S.C. 654), announcing
its intention to proceed to rulemaking to reduce occupational exposure
to 2-EE, 2-EEA, 2-ME, and 2-MEA (Ref. 6). On March 23, 1993 (58 FR
15526), OSHA published a proposed rule that would reduce the chemicals'
PELs and provide other protective measures for the approximately 46,000
workers exposed to the substances (Ref. 7). After publishing the 1993
proposal, OSHA held informal public hearings on the proposal, and the
record closed in March 1994 (Ref. 8).
3. EPA regulatory activities in the 1990's. In the period
immediately after OSHA published its proposed rule, EPA, on July 27,
1993 (58 FR 40262) (Ref. 9), promulgated a TSCA section 4 test rule to
require neurotoxicity testing of 2-EE (among other chemical
substances). The required testing was based on suggestive evidence of
neurotoxicity involving the alteration of motor performance and
avoidance conditioning in the offspring of rats exposed to 100 and 200
parts per million (ppm) (Refs. 10 and 11), as well as substantial
occupational and consumer exposure, and substantial environmental
release (Ref. 12). After publication of that rule, however, the
producers of 2-EE told EPA that there were no consumer uses of 2-EE
(Ref. 13). Given this information, and because OSHA was continuing to
work toward revising the PELs for glycol ethers, EPA believed that
exposure to 2-EE was not substantial and revoked the TSCA section 4
testing requirements for 2-EE in a settlement agreement with producers
in 1994 (Ref. 13). The settlement agreement required that the Chemical
Manufacturers Association (now the American Chemistry Council (ACC))
and the manufacturers and processors of these chemicals perform certain
neurotoxicity and pharmacokinetics testing on 7 of the 10 chemicals
subject to the final neurotoxicity test rule (Ref. 14). This revocation
was also reflected in the January 23, 1995 Federal Register (60 FR
4514) (FRL-4924-7) (Ref. 15). At the time that EPA was considering
revoking the testing requirements in the section 4 rule, the Agency
also believed it would be prudent to provide some mechanism to monitor
the possible re-emergence of the consumer use of 2-EE. Therefore, in
the same notice in which it proposed to revoke the testing requirements
of 2-EE (59 FR 33187, June 27, 1994) (Ref. 14), EPA announced its
intention to propose and promulgate a SNUR. The parties to the
settlement agreement supported such a SNUR (Ref. 13).
4. Final OSHA regulatory actions. OSHA reopened the record on
August 8, 2002 seeking comment on how the substances were being used in
the workplace, including their level of production, and the industries
and processes in which they were used (Ref. 16). Based on the
information submitted during this comment period, OSHA determined that
a major decline in the production of the substances was apparent and
that their use in several key industry sectors has been eliminated or
is in the process of being phased out. Additionally, OSHA determined
that where these substances were still being manufactured, their
production was virtually limited to ``closed systems'' and average
exposures already were at or below the proposed PEL (Ref. 8). OSHA
concluded that the proposed rule was no longer necessary and withdrew
its proposed Glycol Ethers rule on December 31, 2003 (Ref. 8).
B. What are the Uses and Production Levels of these Chemicals?
The chemical substances 2-EE, 2-EEA, 2-ME, and 2-MEA, are
considered members of a broad class of chemicals known as ethylene
glycol ethers. As with other glycol ethers, 2-EE, 2-EEA, 2-ME, and 2-
MEA are colorless, flammable liquids which are compatible with a broad
range of resins and can be mixed with both organic solvents and water.
They have relatively low vapor pressures, high boiling points, low
evaporation rates and high flash points. Due to these physical
characteristics, 2-EE, 2-EEA, 2-ME, and 2-MEA are potentially useful in
a wide variety of applications, particularly as solvents (Ref. 7). They
have been used in many industrial and consumer products, but concerns
for their health effects have caused these uses to be severely
curtailed in recent years.
U.S. production of 2-EE peaked at 200.7 million pounds in 1980 and
had decreased to 118 million pounds by 1999. U.S. consumption of 2-EE
(including consumption to manufacture 2-EEA) was 175 million pounds in
1980, and down to 53 million pounds in 1999, of which, 52 of the 53
million pounds was used to manufacture 2-EEA. U.S. consumption of 2-EE
for uses other than acetate production was less than 1 million pounds.
Production and/or imports of 2-EE were below 100 million pounds based
on data collected for the 2002 TSCA section 8(a) Inventory Update Rule
(IUR) (see 40 CFR part 710) (Ref. 17).
U.S. production of 2-EEA dropped from 136.7 million pounds in 1984
to 72 million pounds in 1999. In 1999, all but one million of those
pounds were exported. Data collected for the 2002 IUR show production
and/or import levels of less than 100 million pounds (Ref. 17).
[[Page 9905]]
U.S. production of 2-ME, which peaked at 97.3 million pounds in
1980, was down to 55 million pounds by 1999 (at which time most 2-ME
produced was exported). U.S. consumption, still 50 to 53 million pounds
in the early 1990's, had declined to approximately 3 million pounds in
1999. 2002 IUR data show that production and/or import was less than 50
million pounds (Ref. 17).
U.S. production of 2-MEA in 1991 was estimated to be 0.5 million
pounds. There were no reports of 2-MEA production or import under the
IUR in 1994, 1998, and 2002 (Ref. 17). Therefore, EPA is proposing that
persons intending to manufacture or import 2-MEA at levels greater than
10,000 pounds per year as well as persons intending to manufacture,
import, or process 2-EE, 2-EEA, 2-ME, or 2-MEA for domestic use in a
consumer product to submit a SNUN to EPA at least 90 days before such
manufacture, import, or processing.
Production of the E-series glycol ethers, i.e., ethanol based
glycol ethers and their acetates, had been declining or has ceased and
EPA believes there is no ongoing use of these chemicals in consumer
products in the U.S. In response to a proposed TSCA section 4 test
rule, manufacturers of 2-EE told EPA that there was no consumer use of
2-EE (Ref. 13). In 2004, a representative for the Ethylene Glycol
Ethers Panel of the ACC confirmed that concerns over the toxicity of E-
series glycol ethers has subsequently resulted in the elimination of E-
series glycol ethers from all consumer products in the 1980's and the
development of alternatives to 2-ME, 2-EE, and 2-EEA (Ref. 18).
C. What are the Potential Routes of Exposure?
Despite the diminished potential for human exposure due to the
decline in production and use in industrial products and the
termination of the chemicals' use in consumer products as discussed in
Unit III.B., EPA believes there may still be some potential for human
exposure to 2-EE, 2-EEA, 2-ME, and 2-MEA. Their physical
characteristics discussed in Unit III.B. make them useful in a variety
of applications, particularly as solvents. ``A major route of exposure
is the skin. The ubiquity of solvents and the casual approach [of
consumers] to their use almost assure skin contact with liquid
solvents.'' (Ref. 19). Also, as members of the ethylene series (``E-
series'' used in Unit III.B.) of glycol ethers, 2-EE, 2-EEA, 2-ME, and
2-MEA are well absorbed from the skin. They are so readily absorbed
through the skin that the dermal to oral 50% lethal dose
(LD50) ratio is approximately one (Ref 19).
Although 2-EE, 2-EEA, 2-ME, and 2-MEA are not highly volatile, high
vapor concentrations can be generated under the conditions of solvent
use. When glycol ether vapors enter the lungs they can readily diffuse
across respiratory membranes and enter the bloodstream (Ref. 19).
D. What are the Potential Sources of Exposure?
EPA believes that 2-EE, 2-ME, 2-MEA, and 2-EEA are currently used
only in industrial products. EPA also believes that the documented
decline in production volumes of 2-EE, 2-EEA, 2-ME, and 2-MEA discussed
in Unit III.B. has probably already reduced the potential for
occupational exposure. OSHA reported in late 2003 that production, use,
and exposure to these glycol ethers has ceased or is virtually limited
to closed system production where there is little opportunity for
worker exposure. Exposure levels in those operations already are at or
below the proposed PELs. In addition, use of these glycol ethers has
largely been replaced by less-toxic substitutes, such as E-series butyl
glycol ethers, other ethylene glycol ethers, propylene glycol ethers,
and other types of solvents (Ref. 8). A decline in environmental
release of 2-EE is reflected in Toxics Release Inventory (TRI) data
from the years 1987 through 1996 which indicates a steady decline from
2,770,113 pounds in 1987 to 192,468 pounds in 1996 (Ref. 20) to 103,513
pounds in 2001 (Ref. 17).
EPA has found evidence which suggests that 2-EE, as well as 2-ME,
2-MEA, and 2-EEA, are not currently used in consumer products (Ref.
17), and the manufacturers of 2-EE which were parties to the 1994
settlement agreement told EPA that, to the best of their knowledge,
there were, at that time, no consumer uses of 2-EE (Refs. 9 and 13).
The ACC also reported in 2001, citing the SRI Chemical Economics
Handbook as its source, that the remaining domestic consumption of 2-EE
is in non-consumer solvents for paints, coatings, and other industrial
uses; the only remaining domestic use of 2-EEA is in machinery and
equipment paints and coatings; and the only remaining use of 2-ME,
other than as a chemical intermediate, is as a jet fuel deicer. No
information on current uses of 2-MEA was identified (Ref. 17).
E. What are the Health Effects of these Chemicals?
Toxicity studies in rats, rabbits, mice, and monkeys via
inhalation, dermal, and oral exposure, have shown clearly and
consistently that 2-EE and 2-ME can cause adverse hematologic,
reproductive, and developmental effects. These effects include
decreased white and red blood cell counts, decreased hemoglobin,
decreased fertility, decreased sperm count, decreased testes size and
weight, increased resorptions, increased fetal malformations, and
behavioral and neurochemical alterations in the neonate (Refs. 7 and
2).
Although data on workers is often compromised by confounding
exposure to other solvents, studies of workers exposed to 2-ME and 2-EE
have documented adverse effects on the hematologic and male
reproductive systems. Blood effects observed among the exposed workers
include bone marrow injury, reduced red and white blood cell counts,
and anemia, while the major reproductive effect observed is reduced
sperm count (Ref. 7). Thus, although the human data have their
limitations, there is evidence of certain adverse effects in humans
exposed to 2-EE and 2-ME and this evidence is consistent with a strong
body of evidence of the same or similar effects in experimental
animals.
Animal studies with 2-EEA and 2-MEA have shown that these acetates
induce adverse reproductive, developmental, and hematological effects
similar to those ascribed to their parent glycol ethers, 2-EE and 2-ME.
These studies confirm the findings of metabolic studies which indicate
that 2-ME, 2-EE, and their acetates follow similar metabolic pathways,
producing the same metabolites, which are the active agents most likely
responsible for the observed effects (Ref. 7).
IV. Determining a Significant New Use
Section 5(a)(2) of TSCA provides that EPA's determination that a
use of a chemical substance is a significant new use must be made after
consideration of all relevant factors including:
The projected volume of manufacturing and processing of a
chemical substance.
The extent to which a use changes the type or form of
exposure of human beings or the environment to a chemical substance.
The extent to which a use increases the magnitude and
duration of exposure of human beings or the environment to a chemical
substance.
The reasonably anticipated manner and methods of
manufacturing, processing, distribution in commerce, and disposal of a
chemical substance.
EPA construes the statute to allow consideration of any other
relevant factors, in addition to those enumerated
[[Page 9906]]
in section 5(a)(2)(A) through (D) of TSCA.
To determine what would constitute a significant new use of 2-EE,
2-EEA, 2-ME, and 2-MEA, EPA considered relevant information about the
toxicity of the substances, likely exposures/releases associated with
possible uses, and the four factors listed in section 5(a)(2) of TSCA.
The latest information available to EPA indicates that there is no
ongoing domestic use of 2-EE, 2-EEA, 2-ME, or 2-MEA in consumer
products. EPA believes that the renewed use of 2-EE, 2-EEA, 2-ME, or 2-
MEA in a consumer product would increase the magnitude and duration of
exposure. Considering the health concerns for 2-EE, 2-EEA, 2-ME, and 2-
MEA, EPA believes that individuals could suffer adverse effects from
their use in consumer products. Thus, EPA is proposing to designate
``domestic use in a consumer product'' as well as the manufacture or
import of 2-MEA at levels greater than 10,000 pounds per year as a
significant new use of 2-EE, 2-EEA, 2-ME, and 2-MEA.
Based on these considerations, EPA is pursuing the following
objectives with regard to the use of 2-EE, 2-EEA, 2-ME, and 2-MEA in
consumer products:
EPA wants to ensure that it would receive notice of any
person's intent to manufacture or import 2-MEA at levels greater than
10,000 pounds per year or intending to manufacture, import, or process
2-EE, 2-EEA, 2-ME, and 2-MEA for domestic use in a consumer product
before that activity begins.
EPA wants to ensure that it would have the opportunity to
review and evaluate data submitted in a SNUN before the notice
submitter begins manufacturing, importing, or processing 2-EE, 2-EEA,
2-ME, and 2-MEA for domestic use in a consumer product or manufacturing
or importing 2-MEA at levels greater than 10,000 pounds per year.
EPA wants to ensure that it would be able to regulate
prospective manufacturers, importers, or processors of 2-EE, 2-EEA, 2-
ME, and 2-MEA before use of any of these chemicals in a consumer
product occurs, provided that the degree of potential risk is
sufficient to warrant such regulation.
As noted in Unit III.B., the production of the chemicals included
in this SNUR have declined significantly over time. EPA is not aware of
current domestic consumer uses for the chemicals, and substitutes are
available. The Agency will use information submitted pursuant to the
Inventory Update Rule (40 CFR part 710) to track the production volumes
and uses of these chemicals. If needed, EPA may pursue additional
regulatory actions as appropriate under TSCA sections 4, 5, 6, or 8.
V. Test Data and Other Information
EPA recognizes that section 5 of TSCA does not require the
development of any particular test data before submission of a SNUN.
Persons are required only to submit test data in their possession or
control and to describe any other data known to or reasonably
ascertainable by them (15 U.S.C. 2604(d); 40 CFR 721.25).
However, SNUN submitters should be aware that EPA will be better
able to evaluate SNUNs which provide detailed information on:
Human exposure and environmental releases that may result
from the significant new use of the chemical substances.
Potential benefits of the chemical substances.
Information on risks posed by the chemical substances
relative to risks posed by potential substitutes.
Submitters should consider including with a SNUN any other
available studies on the chemical substances or studies on analogous
substances which may demonstrate that the significant new uses being
reported are unlikely to present an unreasonable risk.
In view of the potential risks posed by these chemicals, EPA would
recommend that potential SNUN submitters include data that would permit
a reasoned evaluation of risks posed by these chemicals. EPA encourages
persons to consult with the Agency before submitting a SNUN for these
substances. As part of this optional pre-notice consultation, EPA would
discuss specific data it believes are necessary to evaluate a
significant new use. A SNUN submitted without sufficient data to
reasonably evaluate risks posed by a significant new use of 2-EE, 2-
EEA, 2-ME, and/or 2-MEA may increase the likelihood that EPA will take
action under TSCA section 5(e) to prohibit or limit activities
associated with these chemicals. EPA recommends that potential SNUN
submitters contact the Agency early enough that they will be able to
conduct any appropriate tests.
VI. Recordkeeping Requirements
In addition to the recordkeeping requirements of 40 CFR 721.40
which require persons subject to a SNUR to retain documentation of
information contained in a SNUN, EPA is proposing to require the
recordkeeping requirements in 40 CFR 721.125 (a), (b), and (c) in this
SNUR. Section 721.125(a) requires records documenting manufacture and
importation volume and dates; Sec. 721.125(b) documents volumes
purchased in the U.S. by processors, the names and addresses of
suppliers, and the dates of purchase; and Sec. 721.125(c) requires
records documenting the names and addresses (including shipment
destination address, if different) of all persons outside the site of
manufacture, importation, or processing to whom the manufacturer,
importer, or processor directly sells or transfers the substance, the
date, and the quantity of each sale or transfer. EPA is also proposing
to require the maintenance of records documenting the compliance with
the significant new use of domestic use in a consumer product or the
manufacture or import of 2-MEA at levels greater than 10,000 pounds per
year. For the significant new use of 2-MEA manufacture or import at
levels greater than 10,000 pounds per year, records required by Sec.
721.125(a) would be sufficient. For the significant new use of domestic
use in a consumer product, required documentation must demonstrate
compliance with the significant new use, i.e.,: 1) That 2-EE, 2-EEA, 2-
ME or 2-MEA were not manufactured, imported, or processed for use in a
consumer product; and, 2) that, where no significant new use notice is
filed, any recipients of these chemicals either (a) were notified of
the SNUR and its provisions by the manufacturer, importer, or
processor, (b) knew of the SNUR independently, or (c) cannot undertake
the significant new use. See 40 CFR 720.5(a)(2). These records will
enable EPA to determine compliance with the SNUR.
VII. SNUN Submissions
SNUNs should be mailed to the Environmental Protection Agency, OPPT
Document Control Office (7407M), 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. Information must be submitted in the form
and manner set forth in EPA Form No. 7710-25. This form is available
from the Environmental Assistance Division (7408M), OPPT, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001 (see 40 CFR 721.25(a) and 720.40(a)(2)(i)).
VIII. Alternatives
Before proposing this SNUR, EPA considered promulgating a TSCA
section 8(a) reporting rule for 2-EE, 2-EEA, 2-ME, and 2-MEA. Under
such a rule, EPA could generally require any person to report
information to the Agency when they intend to manufacture, import, or
process 2-EE, 2-EEA, 2-ME, or 2-MEA. However, in the case of these
particular substances, the
[[Page 9907]]
use of TSCA section 8(a) rather than SNUR authority would have several
drawbacks. First, EPA would not be able to take immediate follow-up
regulatory action under TSCA sections 5(e) or 5(f) to prohibit or limit
the activity before it begins. In addition, EPA may not receive
important information from small businesses, because such firms
generally are exempt from TSCA section 8(a) reporting requirements. In
view of the level of health concerns for 2-EE, 2-EEA, 2-ME, and 2-MEA,
EPA believes that a TSCA section 8(a) rule for these substances would
not meet EPA's regulatory objectives.
Currently 2-EE, 2-EEA, 2-ME, and 2-MEA are not subject to any other
Federal regulation which would notify the Federal Government of
activities that might result in adverse exposures associated with the
proposed significant new uses, or provide a mechanism that could
protect against potentially adverse exposures associated with those
uses before they occur.
IX. Applicability of Rule to Uses Occurring Before Effective Date of
the Final Rule
As discussed in the Federal Register of April 24, 1990 (55 FR
17376), EPA believes that the intent of TSCA section 5(a)(1)(B) is best
served by designating a use as a significant new use as of the date of
publication of the proposed SNUR rather than as of the effective date
of the final rule. If uses begun after publication of the proposed SNUR
were considered to be ongoing rather than new, it would be difficult
for EPA to establish SNUR notice requirements, because any person could
defeat the SNUR by initiating the proposed significant new use before
the rule became final.
Any person who, after publication of this proposed SNUR, begins to
manufacture, import, or process 2-EE, 2-EEA, 2-ME, or 2-MEA for a
proposed significant new use must stop such activity before the
effective date of the final rule. Persons who cease those activities
will have to meet all SNUR notice requirements and wait until the end
of the notice review period, including all extensions, before engaging
in any activities designated as significant new uses. If, however,
persons who begin to manufacture, import, or process any of these
chemicals between the proposal and the effective date of the final SNUR
meet the conditions of advance compliance as codified at 40 CFR
721.45(h), those persons would be considered to have met the
requirements of the final SNUR for those activities.
X. Economic Analysis
EPA has evaluated the potential costs of establishing SNUR
reporting requirements for potential manufacturers, importers, and
processors of the chemical substances included in this proposed rule.
While there is no precise way to calculate the total annual cost of
compliance with the final rule, given the uncertainties related to
predicting the number of SNUN's that would be submitted as a result of
this SNUR, EPA estimates that the cost for preparing and submitting a
SNUN is $7,174, including a $2,500 user fee required by 40 CFR part
700.45(b)(2)(iii) (Ref. 18). Small businesses with annual sales of less
than $40 million when combined with those of the parent company (if
any) are subject to a reduced user fee of $100 (40 CFR part
700.45(b)(1)). Based on past experience with SNURs and the low number
of SNUNs which are submitted on an annual basis, EPA believes that
there will be few, if any, SNUNs submitted as a result of this SNUR.
The costs of submission of SNUNs will not be incurred by any company
unless a company decides to pursue a significant new use as defined in
this SNUR. Furthermore, while the expense of a notice and the
uncertainty of possible EPA regulation may discourage certain
innovations, that impact would be limited because such factors are
unlikely to discourage an innovation that has high potential value.
EPA's complete economic analysis is available in the public docket for
this proposed rule (Ref. 18).
Under section 12(b) of TSCA, exporters must notify EPA if they
export or intend to export a chemical substance or mixture for which a
rule has been proposed or promulgated under section 5 or 6. Notice must
be provided for the first export or intended export to a particular
country in a calendar year. In an economic analysis of an amendment to
the rules implementing TSCA section 12(b), EPA estimated that the one-
time cost of preparing and submitting an export notification was $62.60
in 1992, or $93.02 when inflated to 2003 dollars by a factor of
approximately 1.5, from the Employment Cost Index for White Collar
Occupations. The total costs of export notification will vary per
chemical, depending on the number of required notifications (i.e.,
number of countries to which the chemical is exported). EPA is unable
to make any estimate of the likely number of export notifications for
chemicals covered in this SNUR (Ref. 17).

XII. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993), the Office of Management and
Budget (OMB) has determined that proposed or final SNURs are not a
``significant regulatory action'' subject to review by OMB, because
they do not meet the criteria in section 3(f) of the Executive Order.
B. Paperwork Reduction Act
According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et
seq., an Agency may not conduct or sponsor, and a person is not
required to respond to a collection of information that requires OMB
approval under the PRA, unless it has been approved by OMB and displays
a currently valid OMB control number. The OMB control numbers for EPA's
regulations in title 40 of the CFR, after appearing in the Federal
Register, are listed in 40 CFR part 9, and included on the related
collection instrument or form, if applicable.
The information collection requirements related to this action have
already been approved by OMB pursuant to the PRA under OMB control
number 2070-0038 (EPA ICR No. 1188). This action would not impose any
burden requiring additional OMB approval. If an entity were to submit a
SNUN to the Agency, the annual burden is estimated to average 105 hours
per submission. This burden estimate includes the time needed to review
instructions, search existing data sources, gather and maintain the
data needed, and complete, review, and submit the required SNUN.
Send any comments about the accuracy of the burden estimate, and
any suggested methods for minimizing respondent burden, including
through the use of automated collection techniques, to the Director,
Collection Strategies Division, Office of Environmental Information
(2822T), Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. Please remember to include the OMB control
number in any correspondence, but do not submit any completed forms to
this address.
C. Regulatory Flexibility Act
Pursuant to section 605(b) of the Regulatory Flexibility Act (RFA)
(5 U.S.C. 601 et seq.), the Agency hereby certifies that promulgation
of this SNUR would not have a significant adverse economic impact on a
substantial number of small entities. The rationale supporting this
conclusion is as follows. A SNUR applies to any person (including small
or large entities) who intends to engage in any activity described in
the rule as a ``significant new use.'' By definition of the word
``new,'' and based on all information currently available to EPA, it
appears that no small or large entities presently engage in such
activity. Since a SNUR only requires that any person who intends to
engage in such activity in the future must first notify EPA by
submitting a SNUN, no economic impact would even occur until someone
decides to engage in those activities. Although some small entities may
decide to conduct such activities in the future, EPA cannot presently
determine how many, if any, there may be. However, EPA's experience to
date is that, in response to the promulgation of over 1,000 SNURs, the
Agency receives on average only 10 notices per year. Of those SNUNs
submitted, none appear to be from small entities in response to any
SNUR. In addition, the estimated reporting cost for submission of a
SNUN (see Unit X.), are minimal regardless of the size of the firm.
Therefore, EPA believes that the potential economic impact of complying
with this SNUR is not expected to be significant or adversely impact a
substantial number of small entities. In a SNUR that published on June
2, 1997 (62 FR 29684) (FRL-5597-1), the Agency presented its general
determination that proposed and final SNURs are not expected to have a
significant economic impact on a substantial number of small entities,
which was provided to the Chief Counsel for Advocacy of the Small
Business Administration.
D. Unfunded Mandates Reform Act
Based on EPA's experience with proposing and finalizing SNURs,
State, local, and Tribal governments have not been impacted by these
rulemakings, and EPA does not have any reasons to believe that any
State, local, or Tribal government would be impacted by this
rulemaking. As such, EPA has determined that this regulatory action
would not impose any enforceable duty, contain any unfunded mandate, or
otherwise have any affect on small governments subject to the
requirements of sections 202, 203, 204, or 205 of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
E. Executive Order 13132: Federalism
This action would not have a substantial direct effect on States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government, as specified in Executive Order 13132, entitled
Federalism (64 FR 43255, August 10, 1999).
F. Executive Order 13175: Consultation and Coordination with Indian
Tribal Governments
This proposed rule would not have Tribal implications because it is
not expected to have substantial direct effects on Indian Tribes. This
proposed rule would not significantly or uniquely affect the
communities of Indian Tribal governments, nor would it involve or
impose any requirements that affect Indian Tribes. Accordingly, the
requirements of Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000), do not apply to this proposed rule.
[[Page 9909]]
G. Executive Order 13045: Protection of Children from Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997), because this is not an economically
significant regulatory action as defined by Executive Order 12866, and
this action does not address environmental health or safety risks
disproportionately affecting children.
H. Executive Order 13211: Actions that Significantly Affect Energy
Supply, Distribution, or Use
This proposed rule is not subject to Executive Order 13211,
entitled Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001),
because this action is not expected to affect energy supply,
distribution, or use.
I. National Technology Transfer Advancement Act
In addition, since this action does not involve any technical
standards, section 12(d) of the National Technology Transfer and
Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15
U.S.C. 272 note), does not apply to this action.
J. Executive Order 12898: Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations
This action does not entail special considerations of environmental
justice related issues as delineated by Executive Order 12898, entitled
Federal Actions to Address Environmental Justice in Minority
Populations and Low-Income Populations (59 FR 7629, February 16, 1994).
K. Executive Order 12988: Civil Justice Reform
In issuing this proposed rule, EPA has taken the necessary steps to
eliminate drafting errors and ambiguity, minimize potential litigation,
and provide a clear legal standard for affected conduct, as required by
section 3 of Executive Order 12988, entitled Civil Justice Reform (61
FR 4729, February 7, 1996).
List of Subjects in 40 CFR Part 721
Environmental protection, Chemicals, Hazardous substances,
Reporting and recordkeeping requirements.
Dated: February 16, 2005.
Charles M. Auer,
Director, Office of Pollution Prevention and Toxics.
Therefore, it is proposed that 40 CFR part 721 be amended as
follows:
PART 721--[AMENDED]
1. The authority citation for part 721 would continue to read as
follows:
Authority: 15 U.S.C. 2604, 2607, and 2625(c).
2. Add new Sec. 721.10001 to subpart E to read as follows:
Sec. 721.10001 2-Ethoxyethanol, 2-ethoxyethanol acetate, 2-
methoxyethanol, and 2-methoxyethanol acetate.
(a) Chemical substances and significant new uses subject to
reporting. (1) The chemical substances identified as 2-ethoxyethanol
(CAS No. 110-80-5), 2-ethoxyethanol acetate (CAS No. 111-15-9), 2-
methoxyethanol (CAS No. 109-86-4), and 2-methoxyethanol acetate (CAS
No. 110-49-6) are subject to reporting under this section for the
significant new use described in paragraph (a)(2) of this section.
(2) The significant new use is domestic use in a consumer product
or the manufacture or import of 2-methoxyethanol acetate at levels
greater than 10,000 pounds per year.
(b) Specific requirements. The provisions of subpart A of this part
apply to this section except as modified by this paragraph.
(1) Recordkeeping. Recordkeeping requirements as specified in Sec.
721.125 (a), (b), and (c) apply to the significant new use specified in
Sec. 721.10001. In addition, records documenting compliance with the
significant new use of domestic use in a consumer product or the
manufacture or import of 2-methoxyethanol acetate at levels greater
than 10,000 pounds per year must be maintained.
