Proposed Significant New Use Rule for 1-Propene, 2,3,3,3-
tetrafluoro-
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) for the
chemical substance identified as 1-Propene, 2,3,3,3-tetrafluoro- (CAS
No. 754-12-1) which was subject to premanufacture notice (PMN) P-07-
601. This proposed rule would require persons who intend to
manufacture, import, or process the substance for an activity that is
designated as a significant new use to notify EPA at least 90 days
before commencing that activity. The required notification would
provide EPA with the opportunity to evaluate the intended use and, if
necessary, to prohibit or limit the activity before it occurs.
DATES: Comments must be received on or before May 3, 2010.

SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this Action Apply to Me?
You may be potentially affected by this action if you manufacture,
import, process, or use the chemical substance contained in this
proposed rule. Potentially affected entities may include, but are not
limited to:
Manufacturers, importers, or processors of the subject
chemical substance (NAICS codes 325 and 324110), e.g., chemical
manufacturing and petroleum refineries.
This listing is not intended to be exhaustive, but rather provides
a guide for readers regarding entities likely to be affected by this
action. Other types of entities not listed in this unit could also be
affected. The North American Industrial Classification System (NAICS)
codes have been provided to assist you and others in determining
whether this action might apply to certain entities. To determine
whether you or your business may be affected by this action, you should
carefully examine the applicability provisions in Sec. 721.5. If you
have any questions regarding the applicability of this action to a
particular entity, consult the technical person listed under FOR
FURTHER INFORMATION CONTACT.
This action may also affect certain entities through pre-existing
import certification and export notification rules under TSCA. Chemical
importers are subject to the TSCA section 13 (15 U.S.C. 2612) import
certification requirements promulgated at 19 CFR 12.118 through 12.127
and 19 CFR 127.28 (the corresponding EPA policy appears at 40 CFR part
707, subpart B). Chemical importers must certify that the shipment of
the chemical substance complies with all applicable rules and orders
under TSCA. Importers of chemicals subject to a final SNUR must certify
their compliance with the SNUR requirements. In addition, any persons
who export or intend to export a chemical substance that is the subject
of this proposed rule on or after May 3, 2010 are subject to the export
notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see
Sec. 721.20) and must comply with the export notification requirements
in 40 CFR part 707, subpart D.
B. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or e-mail. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM
that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and
then identify electronically within the disk or CD-ROM the specific
information that is claimed as CBI. In addition to one complete version
of the comment that includes information claimed as CBI, a copy of the
comment that does not contain the information claimed as CBI must be
submitted for inclusion in the public docket. Information so marked
will not be disclosed except in accordance with procedures set forth in
40 CFR part 2.
2. Tips for preparing your comments. When submitting comments,
remember to:
i. Identify the document by docket ID number and other identifying

Federal Regulations (CFR) part or section number.
iii. Explain why you agree or disagree; suggest alternatives and
substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information
and/or data that you used.
v. If you estimate potential costs or burdens, explain how you
arrived at your estimate in sufficient detail to allow for it to be
reproduced.
vi. Provide specific examples to illustrate your concerns and
suggest alternatives.
vii. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
viii. Make sure to submit your comments by the comment period
deadline identified.
II. Background
A. What Action is the Agency Taking?
EPA is proposing a significant new use rule (SNUR) under section
5(a)(2) of TSCA for the chemical substance
[[Page 16708]]
identified as 1-Propene, 2,3,3,3-tetrafluoro- (PMN P-07-601; CAS No.
754-12-1). This SNUR would require persons who intend to manufacture,
import, or process the chemical substance for any activity designated
as a significant new use to notify EPA at least 90 days before
commencing the activity.
In the Federal Register of February 1, 2010 (75 FR 4983) (FRL-8438-
4), EPA issued a direct final SNUR for the substance in accordance with
the procedures at Sec. 721.170(d)(4)(i). EPA received notice of intent
to submit adverse comments on this SNUR. Therefore, as required by at
Sec. 721.170(d)(4)(i), EPA is withdrawing the direct final SNUR, which
is published elsewhere in this Federal Register and is now issuing this
proposed SNUR on this substance. The record for the direct final SNUR
on this substance was established as docket EPA-HQ-OPPT-2009-0918. That
record includes information considered by the Agency in developing the
direct final rule and the notice of intent to submit adverse comments.
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, TSCA section 5(a)(1)(B) requires persons to submit a significant
new use notice (SNUN) to EPA at least 90 days before they manufacture,
import, or process the chemical substance for that use. The mechanism
for reporting under this requirement is established under Sec. 721.5.
C. Applicability of General Provisions
General provisions for SNURs appear in 40 CFR part 721, subpart A.
These provisions describe persons subject to the rule, recordkeeping
requirements, exemptions to reporting requirements, and applicability
of the rule to uses occurring before the effective date of the final
rule. Provisions relating to user fees appear at 40 CFR part 700.
According to Sec. 721.1(c), persons subject to this SNUR must comply
with the same notice requirements and EPA regulatory procedures as
submitters of PMNs under TSCA section 5(a)(1)(A). 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), (h)(2), (h)(3), and (h)(5), and the regulations at 40 CFR part
720. Once EPA receives a SNUN, EPA may take regulatory action under
TSCA section 5(e), 5(f), 6, or 7 to control the activities for 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.
Chemical importers are subject to the TSCA section 13 (15 U.S.C.
2612) import certification requirements promulgated at 19 CFR 12.118
through 12.127, and 19 CFR 127.28 (the corresponding EPA policy appears
at 40 CFR part 707, subpart B). Chemical importers must certify that
the shipment of the chemical substance complies with all applicable
rules and orders under TSCA. Importers of chemical substances subject
to a final SNUR must certify their compliance with the SNUR
requirements. In addition, any persons who export or intend to export a
chemical substance identified in a final SNUR are subject to the export
notification provisions of TSCA section 12(b) (15 U.S.C. 2611 (b)) (see
Sec. 721.20) and must comply with the export notification requirements
in 40 CFR part 707, subpart D.
III. Significant New Use Determination
Section 5(a)(2) of TSCA states 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.
In addition to these factors enumerated in TSCA section 5(a)(2),
the statute authorized EPA to consider any other relevant factors.
To determine what would constitute a significant new use for the
chemical substance that is the subject of this proposed SNUR, EPA
considered relevant information about the toxicity of the chemical
substance, likely human exposures and environmental releases associated
with possible uses, and the four bulleted TSCA section 5(a)(2) factors
listed in this Unit.
For the chemical substance 1-Propene, 2,3,3,3-tetrafluoro- (PMN P-
07-601; CAS No. 754-12-1), EPA did not find that the use scenarios
described in the PMN triggered the determination set forth under
section 5(e) of TSCA. EPA did, however, determine that certain changes
from the use scenario described in the PMN could result in increased
exposures, thereby constituting a ``significant new use.'' EPA has
determined that activities proposed as a ``significant new use''
satisfy the two requirements stipulated in Sec. 721.170(c)(2), i.e.,
these significant new use activities: ``(i) are different from those
described in the premanufacture notice for the substance, including any
amendments, deletions, and additions of activities to the
premanufacture notice, and (ii) may be accompanied by changes in
exposure or release levels that are significant in relation to the
health or environmental concerns identified'' for the PMN substance.
IV. Substance Subject to this Proposed Rule and Basis for the Action
EPA is proposing to establish significant new use and recordkeeping
requirements for the chemical substance identified as 1-Propene,
2,3,3,3-tetrafluoro- (PMN P-07-601; CAS No. 754-12-1). The specific
activities proposed as significant new uses and other requirements are
listed in 40 CFR 721.10182 of the proposed regulatory text.
PMN Number P-07-601
Chemical name: 1-Propene, 2,3,3,3-tetrafluoro-.
CAS number: 754-12-1.
Basis for action: The PMN states that the substance will be used as a
motor vehicle air conditioning (MVAC) refrigerant in new passenger cars
and vehicles (i.e., as defined in 40 CFR 82.32 (c) and (d)). Initial
charging of MVAC units with the PMN substance will be done by the motor
vehicle original equipment manufacturer. All servicing, maintenance,
and disposal involving the PMN substance will be done only by Clean Air
Act (CAA) section 609 certified technicians using CAA section 609
certified refrigerant handling equipment. Based on test data on the PMN
substance, EPA identified health concerns for developmental toxicity
and lethality to workers and consumers if they were exposed to a
significant amount of the PMN substance via inhalation. The PMN
substance has an ozone depletion potential of zero, and, based on test
data, has a low global warming potential (GWP100 of about 4). For the
use scenario described in the PMN, significant industrial or commercial
worker exposure is unlikely
[[Page 16709]]
due to the use of CAA section 609 certified refrigerant handling
equipment and other protective measures. Potential consumer (vehicle
passenger) exposure from refrigerant leaks into the passenger
compartment of a vehicle is not expected to present significant risk of
serious health effects. Flammability concerns with the PMN substance
are being addressed through regulatory actions by EPA's Office of Air
and Radiation (see the following paragraph). Further, ``do-it-
yourself'' consumer exposures are not expected because the PMN
substance only will be sold or distributed in 20-pound containers or
larger. Therefore, EPA has not determined that the manufacturing,
processing, or use of the substance as described in the PMN may present
an unreasonable risk. EPA has determined, however, that (1) use of the
substance other than as a MVAC refrigerant in new passenger cars and
vehicles as defined in 40 CFR 82.32 (c) and (d), (2) initial charging
of MVAC units with the PMN substance by any person other than CAA
section 609 certified technicians without using CAA section 609
certified refrigerant handling equipment, (3) servicing, maintenance,
and disposal involving the PMN substance by persons other than CAA
section 609 certified technicians without using CAA section 609
certified refrigerant handling equipment, or (4) sale or distribution
of the PMN substance in containers smaller than 20-pounds (net weight)
may cause serious health effects in accordance with 40 CFR
721.170(b)(3)(i).
This proposed SNUR is intended to complement recently proposed and
forthcoming regulations on the PMN substance under the CAA in that this
SNUR addresses health risk issues of the subject refrigerant. On
October 19, 2009, EPA published a proposed rule on the PMN substance
entitled ``Protection of Stratospheric Ozone: New Substitute in the
Motor Vehicle Air Conditioning Sector under the Significant New
Alternatives Policy (SNAP) Program'' (74 FR 53445) (FRL-8969-7). The
SNAP Program, mandated under section 612 of the CAA, requires EPA to
develop a program for evaluating alternatives to ozone-depleting
substances and to create lists of substitutes for specific uses that do
not present greater overall risk to human health and the environment
than other alternatives that are available. In the October 19, 2009,
action, EPA proposed to find HFO-1234yf acceptable, subject to certain
use conditions, as a substitute for CFC-12 in new motor vehicle air
conditioning systems (passenger cars and trucks). The proposed use
conditions include incorporation of engineering strategies and/or
devices to mitigate flammability risks for this substance (see Unit V.
of the proposed SNAP rule). Use of most flammable refrigerants,
including the PMN substance, in existing MVAC systems as a retrofit has
previously been determined by EPA to be unacceptable. The proposed SNAP
rule would require a petition and a new SNAP submission specifically
for the use of the PMN substance in existing MVAC equipment as a
retrofit before EPA would consider allowing such use (see Unit VI. of
the proposed SNAP rule). EPA also intends to promulgate a follow-on
rulemaking under section 609 of the CAA to address service equipment,
technician certification, and end-of-life disposal specifications.
Recommended testing: EPA has determined that the results of an acute
inhalation toxicity study (OPPTS Harmonized Test Guideline 870.1300 or
Organisation for Economic Co-operation and Development (OECD) 403 test
guideline) with rabbits would help characterize the human health
effects of the PMN substance. Exposure concentrations of 10,000,
50,000, and 100,000 parts per million (ppm) should be used. Further,
rabbits should be exposed for 1 hour, and pregnant rabbits should be
exposed on Gravid Day 12.
CFR citation: 40 CFR 721.10182.
V. Rationale and Objectives of the Proposed Rule
A. Rationale
During the review of the chemical substance P-07-601, EPA
determined that one or more of the criteria of concern established at
Sec. 721.170 were met, as discussed in Unit IV.
B. Objectives
EPA is proposing this SNUR for a chemical substance that has
undergone premanufacture review because the Agency wants to achieve the
following objectives with regard to the significant new uses designated
in this proposed rule:
EPA would receive notice of any person's intent to
manufacture, import, or process a listed chemical substance for the
described significant new use before that activity begins.
EPA would have an opportunity to review and evaluate data
submitted in a SNUN before the notice submitter begins manufacturing,
importing, or processing a listed chemical substance for the described
significant new use.
EPA would be able to regulate prospective manufacturers,
importers, or processors of a listed chemical substance before the
described significant new use of that chemical substance occurs,
provided that regulation is warranted pursuant to TSCA sections 5(e),
5(f), 6, or 7.
Issuance of a SNUR for a chemical substance does not signify that
the chemical substance is listed on the TSCA Inventory. Guidance on how
to determine if a chemical substance is on the TSCA Inventory is
available on the Internet at http://www.epa.gov/opptintr/newchems/pubs/invntory.htm.
VI. Applicability of the Proposed Rule to Uses Occurring Before
Effective Date of the Final Rule
To establish a significant ``new'' use, EPA must determine that the
use is not ongoing. EPA solicits comments on whether any of the uses
proposed as significant new uses are ongoing.
As discussed in the Federal Register of April 24, 1990 (55 FR
17376), EPA has decided 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 rule rather than as of the
effective date of the final rule. If uses begun after publication of
the proposed rule were considered ongoing rather than new, it would be
difficult for EPA to establish SNUR notice requirements because a
person could defeat the SNUR by initiating the significant new use
before the rule became final, and then argue that the use was ongoing
before the effective date of the final rule. Thus, persons who begin
commercial manufacture, import, or processing with the chemical
substances that would be regulated as a ``significant new use'' through
this proposed rule, must cease any such activity before the effective
date of the rule if and when finalized. To resume their activities,
these persons would have to comply with all applicable SNUR notice
requirements and wait until the notice review period, including all
extensions, expires.
EPA has promulgated provisions to allow persons to comply with this
proposed SNUR before the effective date. If a person were to meet the
conditions of advance compliance under Sec. 721.45(h), the person
would be considered to have met the requirements of the final SNUR, for
those activities.
VII. Test Data and Other Information
EPA recognizes that TSCA section 5 does not require developing any
particular test data before submission of a SNUN, except where the
chemical substance subject to the SNUR is also subject to a test rule
under TSCA section 4 (see TSCA section 5(b)).
[[Page 16710]]
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 (see Sec. 720.50). However, upon review of PMNs
and SNUNs, the Agency has the authority to require appropriate testing.
EPA recommended certain testing listed in Unit IV. Descriptions of
tests are provided for informational purposes. EPA strongly encourages
persons, before performing any testing, to consult with the Agency
pertaining to protocol selection. To access the OPPTS harmonized test
guidelines referenced in this document electronically, please go to
http://www.epa.gov/oppts and select ``Test Methods and Guidelines.''
The Organisation for Economic Co-operation and Development (OECD) test
guidelines are available from the OECD Bookshop at http://www.oecdbookshop.org or SourceOECD at http://www.sourceoecd.org.
The recommended test(s) may not be the only means of addressing the
potential risks of the chemical substance. However, SNUNs submitted for
significant new uses without any test data may increase the likelihood
that EPA will take action under TSCA section 5(e), particularly if
satisfactory test results have not been obtained from a prior PMN or
SNUN submitter. EPA recommends that potential SNUN submitters contact
EPA early enough so that they will be able to conduct the appropriate
test(s).
SNUN submitters should be aware that EPA would be better able to
evaluate SNUNs which provide detailed information on the following:
Human exposure and environmental release that may result
from the significant new use of the chemical substance.
Potential benefits of the chemical substance.
Information on risks posed by the chemical substance
compared to risks posed by potential substitutes.
VIII. SNUN Submissions
As stated in Unit II.C., according to Sec. 721.1(c), persons
submitting a SNUN must comply with the same notice requirements and EPA
regulatory procedures as persons submitting a PMN, including submission
of test data on health and environmental effects as described in Sec.
720.50. SNUNs must be submitted to the Environmental Protection Agency
on EPA Form No. 7710-25 in accordance with the procedures set forth in
Sec. Sec. 721.25 and 720.40. This form is available from the
Environmental Assistance Division (7408M), 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001 (see Sec. Sec. 721.25 and 720.40). Forms and
information are also available electronically at http://www.epa.gov/opptintr/newchems.
IX. Economic Analysis
EPA has evaluated the potential costs of establishing SNUN
requirements for potential manufacturers, importers, and processors of
the chemical substance at the time of the direct final rule. The
Agency's complete economic analysis is available in the public docket
for the direct final rule (EPA-HQ-OPPT-2008-0918).
X. References
The official record for this proposed rule has been established.
The following is a listing of the documents that have been placed in
the proposed rule phase of the docket under docket ID number EPA-HQ-
OPPT-2008-0918, which is available for inspection as specified under

XI. Statutory and Executive Order Reviews
A. Executive Order 12866
This proposed rule would establish a SNUR for a chemical substance
that was the subject of a PMN. The Office of Management and Budget
(OMB) has exempted these types of actions from review under Executive
Order 12866, entitled Regulatory Planning and Review (58 FR 51735,
October 4, 1993).
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. EPA would amend the table
in 40 CFR part 9 to list the OMB approval number for the information
collection requirements contained in this proposed rule. This listing
of the OMB control numbers and their subsequent codification in the CFR
satisfies the display requirements of PRA and OMB's implementing
regulations at 5 CFR part 1320. This Information Collection Request
(ICR) was previously subject to public notice and comment prior to OMB
approval, and given the technical nature of the table, EPA finds that
further notice and comment to amend it is unnecessary. As a result, EPA
finds that there is ``good cause'' under section 553(b)(3)(B) of the
Administrative Procedure Act, 5 U.S.C. 553(b)(3)(B), to amend this
table without further notice and comment.
The information collection requirements related to this action have
already been approved by OMB pursuant to PRA under OMB control number
2070-0012 (EPA ICR No. 574). 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 between 30 and
170 hours per response. 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 discussed in this unit. The requirement to submit a SNUN
applies to any person (including small or large entities) who intends
to engage in any activity described in the rule as a ``significant
[[Page 16711]]
new use.'' Because these uses are ``new,'' based on all information
currently available to EPA, it appears that no small or large entities
presently engage in such activities. A SNUR requires that any person
who intends to engage in such activity in the future must first notify
EPA by submitting a SNUN. Although some small entities may decide to
pursue a significant new use 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 1,400 SNURs, the
Agency receives on average only 5 notices per year. Of those SNUNs
submitted from 2006-2008, only one appears to be from a small entity.
In addition, the estimated reporting cost for submission of a SNUN (see
Unit IX.) is minimal regardless of the size of the firm. Therefore, the
potential economic impacts of complying with this SNUR are not expected
to be significant or adversely impact a substantial number of small
entities. In a SNUR that published in the Federal Register of June 2,
1997 (62 FR 29684) (FRL-5597-1), the Agency presented its general
determination that 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 proposed
rule. As such, EPA has determined that this proposed rule 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
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
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 9,
2000), do not apply to this proposed rule.
G. Executive Order 13045
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
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 and because this action is not a significant
regulatory action under Executive Order 12866.
I. National Technology Transfer and 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
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).
