Tris carbamoyl triazine; Proposed Modification of Significant New 
Uses

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Under section 5(a)(2) of the Toxic Substances Control Act 
(TSCA), EPA is proposing to amend the significant new use rule (SNUR) 
for the chemical substance identified generically as tris carbamoyl 
triazine, which was the subject to premanufacture notice (PMN) P-95-
1098. This action would amend the SNUR to allow certain uses without 
requiring a significant new use notice (SNUN), and would extend SNUN 
requirements to certain additional uses. EPA is proposing this 
amendment based on review of new toxicity test data.

DATES: Comments must be received on or before September 2, 2011.

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 identified generically 
as tris carbamoyl triazine (PMN P-95-1098). 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 
manufacturers 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; 
see also 19 CFR 127.28. 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. 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 a proposed or 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.

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 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.

deadline identified.

II. Background

A. What action is the agency taking?

    In the Federal Register of August 20, 1998 (63 FR 44562) (FRL-5788-
7), EPA published a final SNUR (codified at Sec.  721.9719) for the 
chemical substance identified generically as tris carbamoyl triazine 
(PMN P-95-1098), in accordance with the procedures at Sec.  721.160.
    EPA is proposing to amend the requirements of the SNUR as detailed 
in

[[Page 46680]]

this unit. The modified SNUR would require persons who intend to 
manufacture, import, or process the chemical substance for an activity 
designated as a significant new use to notify EPA at least 90 days 
before commencing that activity. The docket established for this 
proposed SNUR is available under docket ID number EPA-HQ-OPPT-2011-
0108. The docket includes information considered by the Agency in 
developing the final rule and the modified TSCA section 5(e) consent 
order negotiated with the PMN submitter.
PMN Number P-95-1098
    Chemical name: Tris carbamoyl triazine (generic).
    CAS number: Not available.
    Effective date of the TSCA section 5(e) consent order: April 25, 
1997.
    Effective date of the modified TSCA section 5(e) consent order: 
December 1, 2010.
    Federal Register publication date and reference for the final SNUR: 
August 20, 1998 (63 FR 44562).
    Basis for the modified TSCA section 5(e) consent order: The generic 
(non-confidential) use of the PMN substance is as a cross linking 
resin. The original TSCA section 5(e) consent order was issued under 
sections 5(e)(1)(A)(i), 5(e)(1)(A)(ii)(I), and 5(e)(1)(A)(ii)(II) based 
on the findings that the chemical substance may present an unreasonable 
risk of injury to the environment, that it will be produced in 
substantial quantities, and there may be significant or substantial 
human exposure to the chemical substance. The original 5(e) consent 
order required establishment of a hazard communication program; 
established a maximum manufacture and importation volume limit for 
submission of required human health testing; and prohibited purposeful 
or predictable releases of the PMN substance in concentrations that 
exceed 40 parts per billion (ppb) in surface waters. The proposed SNUR 
for this chemical substance is based on and consistent with the 
provisions of the modified TSCA section 5(e) consent order, discussed 
below. The proposed SNUR designates as a ``significant new use'' the 
absence of the protective measures required in the corresponding 
modified consent order.
    Human Health Toxicity Concerns: During the initial PMN review 
process, EPA established a no-observable-effect level (NOEL) of 15 mg/
kg/day and a lowest-observable-effect level (LOEL) of 150 mg/kg/day for 
systemic effects based on the results of a 28-day inhalation study in 
rats on the PMN substance, but did not determine that the PMN substance 
may present an unreasonable risk to human health as a result of 
expected exposure. However, the TSCA section 5(e) consent order 
required the PMN submitter to complete and submit a prenatal 
developmental toxicity study at a certain production volume limit. This 
is consistent with the exposure-based finding pursuant to section 
5(e)(1)(A)(ii)(II) of TSCA. The PMN submitter completed this study and 
based on the results the Agency established a NOEL of 30 mg/kg/day for 
maternal toxicity and 1,000 mg/kg/day for fetal toxicity. Using the 
results from both this prenatal developmental study and the earlier 28-
day study, the Agency then reevaluated the predicted workplace 
exposures and determined that there may be an unreasonable risk of 
maternal and systemic toxicity resulting from unprotected inhalation 
exposure to the PMN substance.
    Ecotoxicity Concerns: In addition, to address Agency environmental 
concerns, the PMN submitter completed a fish early-life stage toxicity 
test and a daphnid chronic toxicity test on the PMN substance. During 
the initial review of the PMN, EPA's preliminary Ecological Structural 
Activity Relationship (EcoSAR) analysis of test data on structurally 
analogous substances resulted in a predicted toxicity to aquatic 
organisms at concentrations that exceed the concentration of concern 
(COC) of 40 ppb of the PMN substance in surface waters. Based on the 
results of the submitted fish and daphnid tests, fish were identified 
as the most sensitive species and a revised COC for aquatic toxicity of 
66 ppb was established. Based on the revised COC, EPA then performed 
environmental modeling assessments for the PMN releases to surface 
waters and determined that the new COC would not be exceeded under 
expected conditions of manufacture, import, processing, distribution in 
commerce, use or disposal of the PMN substance.
    The Agency concluded, after examining this new information and 
reexamining the test data and other information supporting its findings 
under section 5(e)(1)(A)(ii)(I) of TSCA in the original TSCA section 
5(e) consent order, that the finding that certain activities involving 
the substance may present an unreasonable risk of injury to the 
environment is no longer supported. The Agency also concluded that 
certain additional activities involving the substance may present an 
unreasonable risk of injury to human health, pursuant to 
5(e)(1)(A)(ii)(I). To conform with these findings and to protect 
against the remaining potential risks, the Agency has modified the TSCA 
section 5(e) consent order (``modified order''); these modifications 
became effective on December 1, 2010. The modified TSCA section 5(e) 
consent order:
    1. Identifies those forms of the PMN substance that are exempt from 
the provisions of the consent order. These exemptions apply to 
quantities of the PMN substance after it has been completely reacted 
(cured).
    2. Adds protection in the workplace requirements for respiratory 
protection and alternative New Chemical Exposure Limit (NCEL) exposure 
monitoring to address the newly-identified potential risks from 
inhalation exposure in the workplace.
    3. Revises the hazard communication requirements to add the human 
health hazard and exposures and remove the environmental hazards and 
exposures.
    4. Removes all release to water requirements.
    5. Revises the recordkeeping requirements to reflect the 
aforementioned modified consent order requirements.
    The proposed rule would conform to the scope of the significant new 
uses in the SNUR to mirror the modified consent order.
    Recommended testing: EPA has determined that the results of the 90-
day inhalation toxicity test in rats (OPPTS Test Guideline 870.3465) 
would help further characterize the human health effects of the PMN 
substance. The modified TSCA section 5(e) consent order does not 
require submission of the aforementioned information at any specified 
time or production volume. However, the order's restrictions on 
manufacturing, import, processing, distribution in commerce, use and 
disposal of the PMN substance will remain in effect until the order is 
modified or revoked by EPA based on submission of that or other 
relevant information.

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 the TSCA section 5(a)(2) factors, listed in 
Unit III. of this document. Once EPA determines that a use of a 
chemical substance is a significant new use, TSCA section 5(a)(1)(B) 
and 40 CFR part 721 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

[[Page 46681]]

use. Persons who must report are described in Sec.  721.5.
    EPA may respond to SNUNs by, among other things, issuing or 
modifying a TSCA section 5(e) consent order and/or amending the SNUR 
promulgated under TSCA section 5(a)(2). Amendment of the SNUR will 
often be necessary to allow persons other than the SNUN submitter to 
engage in the newly authorized use(s), because even after a person 
submits a SNUN and the review period expires, other persons still must 
submit a SNUN before manufacturing on processing for the significant 
new use. Procedures and criteria for modifying or revoking SNUR 
requirements appear at Sec.  721.185.

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 to 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 authorizes EPA to consider any other relevant factors.
    To determine what would constitute a significant new use for the 
chemical substance identified generically as Tris carbamoyl triazine 
(PMN P-95-1098), EPA considered relevant information about the toxicity 
of the chemical substance, likely human exposures and environmental 
releases associated with possible uses, taking into consideration the 
four bulleted TSCA section 5(a)(2) factors listed in this unit.

IV. Rationale for the Proposed Rule

    During review of PMN P-95-1098, the chemical substance identified 
generically as tris carbamoyl triazine, EPA concluded that regulation 
was warranted under TSCA section 5(e), pending the development of 
information sufficient to make reasoned evaluations of the health or 
environmental effects of this chemical substance. The basis for such 
findings is outlined in Unit II. of this notice and in the Federal 
Register document of August 20, 1998 (63 FR 44562) (FRL-5788-7). Based 
on these findings, a TSCA section 5(e) consent order requiring the use 
of appropriate exposure controls were negotiated with the PMN 
submitter. The SNUR provisions for this chemical substance are 
consistent with the provisions of the original TSCA section 5(e) 
consent order. This SNUR was promulgated pursuant to Sec.  721.160.
    After the review of test data submitted pursuant to the TSCA 
section 5(e) consent order for P-95-1098 (see Unit II.) and 
consideration of the factors included in TSCA section 5(a)(2) (see Unit 
III.), EPA determined that the chemical substance may pose an 
unreasonable risk to human health, but no longer may present an 
unreasonable risk to the environment. Consequently, EPA is proposing 
this modification to the SNUR at Sec.  721.9719 according to procedures 
in Sec. Sec.  721.160 and 721.185 so that SNUR provisions for this 
chemical substance remain consistent with the provisions of the TSCA 
section 5(e) consent order, as modified.

V. Applicability of 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 section 5(a)(1)(B) of TSCA 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 as of the effective date of the 
final rule.
    Thus, any persons who begin commercial manufacture, import, or 
processing activities with the chemical substances that are not 
currently a significant new use under the current rule but which would 
be regulated as a ``significant new use'' if this proposed rule if this 
rule is finalized, must cease any such activity as of 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 
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.

VI. Test Data and Other Information

    EPA recognizes that TSCA section 5 does not require the development 
of any particular test data before submission of a SNUN. There are two 
exceptions:
    1. Development of test data is required where the chemical 
substance subject to the SNUR is also subject to a test rule under TSCA 
section 4 (see TSCA section 5(b)(1)).
    2. Development of test data may be necessary where the chemical 
substance has been listed under TSCA section 5(b)(4) (see TSCA section 
5(b)(2)).
    In the absence of a TSCA section 4 test rule or a TSCA section 
5(b)(4) listing covering the chemical substance, 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. In this case, EPA recommends 
persons, before performing any testing, to consult with the Agency 
pertaining to protocol selection. To access the Harmonized Test 
Guidelines referenced in this document electronically, please go to 
http://www.epa.gov/ocspp and select ``Test Methods and Guidelines.''
    The modified TSCA section 5(e) consent order for the chemical 
substance that would be regulated under this proposed rule does not 
require submission of the test at any specified time or volume. 
However, the restrictions on manufacture, import, processing, 
distribution in commerce, use and disposal of the PMN substance would 
remain in effect until the consent order is modified or revoked by EPA 
based on submission of that or other relevant information. These 
restricted activities cannot be commenced unless the PMN submitter 
first submits the results of toxicity tests that would permit a 
reasoned evaluation of the potential risks posed by this chemical 
substance. The test specified in the modified TSCA section 5(e) consent 
order is included in Unit II. The proposed SNUR would contain the same 
restrictions as the modified TSCA section 5(e) consent order. Persons 
who intend to commence non-exempt commercial manufacture, import, or 
processing for those activities proposed as significant new uses would 
be

[[Page 46682]]

required to notify the Agency by submitting a SNUN at least 90 days in 
advance of commencement of those activities.
    The recommended testing specified in Unit II. of this document may 
not be the only means of addressing the potential risks of the chemical 
substance. However, SNUNs submitted 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 tests.
    SNUN submitters should be aware that EPA will 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.

VII. SNUN Submissions

    According to 40 CFR 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 
on EPA Form No. 7710-25, generated using e-PMN software, and submitted 
to the Agency in accordance with the procedures set forth in Sec. Sec.  
721.25 and 720.40. E-PMN software is available electronically at http://www.epa.gov/opptintr/newchems.

VIII. Economic Analysis

    EPA evaluated the potential costs of establishing SNUN requirements 
for potential manufacturers, importers, and processors of the chemical 
substances during the development of the direct final rule. The 
Agency's complete Economic Analysis is available in the docket under 
docket ID number EPA-HQ-OPPT-2011-0108.

IX. Statutory and Executive Order Reviews

A. Executive Order 12866

    This proposed rule would modify a SNUR for a chemical substance 
that is the subject of a PMN and TSCA section 5(e) consent order. 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 is amending 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 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 SNURs covering over 
1,000 chemicals, the Agency receives only a handful of notices per 
year. For example, the number of SNUNs was four in Federal fiscal year 
2005, eight in FY2006, six in FY2007, eight in FY2008, and seven in 
FY2009. During this five-year period, three small entities submitted a 
SNUN. In addition, the estimated reporting cost for submission of a 
SNUN (see Unit VIII.) is minimal regardless of the size of the firm. 
Therefore, the potential economic impacts of complying with this SNUR 
would not be 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 reason 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,

[[Page 46683]]

contain any unfunded mandate, or otherwise have any effect on small 
governments subject to the requirements of sections 202, 203, 204, or 
205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 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 nor 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).

List of Subjects in 40 CFR Part 721

    Environmental protection, Chemicals, Hazardous substances, 
Reporting and recordkeeping requirements.

    Dated: July 22, 2011.
Wendy C. Hamnett,
Director, Office of Pollution Prevention and Toxics.

    Therefore, 40 CFR part 721 is proposed to be amended as follows:

PART 721--[AMENDED]

    1. The authority citation for part 721 continues to read as 
follows:

    Authority:  15 U.S.C. 2604, 2607, and 2625(c).

    2. Amend Sec.  [emsp14]721.9719 as follows:
    a. Revise the section heading.
    b. Revise paragraphs (a)(1), (a)(2)(i), and (a)(2)(ii).
    c. Remove paragraph (a)(2)(iii).
    d. Revise paragraph (b)(1).
    e. Remove paragraph (b)(3).
    The revisions and addition read as follows:

Sec.  721.9719  Tris carbamoyl triazine.

    (a) * * *
    (1) The chemical substance identified generically as tris carbamoyl 
triazine (PMN P-95-1098) is subject to reporting under this section for 
the significant new uses described in paragraph (a)(2) of this section. 
The requirements of this rule do not apply to quantities of the 
chemical substance after it has been completely reacted (cured).
    (2) * * *
    (i) Protection in the workplace. Requirements as specified in Sec.  
721.63 (a)(4), (a)(5), (a)(6)(v), (b) (concentration set at 1.0 
percent), and (c). Respirators must provide a National Institute for 
Occupational Safety and Health (NIOSH) assigned protection factor (APF) 
of at least 5. As an alternative to the respiratory requirements 
listed, a manufacturer, importer, or processor may choose to follow the 
new chemical exposure limit (NCEL) provisions listed in the Toxic 
Substances Control Act (TSCA) section 5(e) consent order for this 
substance. The NCEL is 1.0 mg/m\3\ as an 8-hour time weighted average. 
Persons who wish to pursue NCELs as an alternative to the Sec.  721.63 
respirator requirements may request to do so under Sec.  721.30. 
Persons whose Sec.  721.30 requests to use the NCELs approach are 
approved by EPA will receive NCELs provisions comparable to those 
contained in the corresponding section 5(e) consent order. The 
following NIOSH-certified respirators meet the requirements for Sec.  
721.63(a)(4):
    (A) Air purifying, tight-fitting half-face respirator equipped with 
the appropriate combination cartridges; cartridges should be tested and 
approved for the gas/vapor substance (i.e., organic vapor, acid gas, or 
substance-specific cartridge) and should include a particulate filter 
(N100 if oil aerosols are absent, R100, or P100);
    (B) Air purifying, tight-fitting full-face respirator equipped with 
the appropriate combination cartridges, cartridges should be tested and 
approved for the gas/vapor substance (i.e., organic vapor, acid gas, or 
substance-specific cartridge) and should include a particulate filter 
(N100 if oil aerosols are absent, R100, or P100);
    (C) Powered air-purifying respirator equipped with loose-fitting 
hood or helmet equipped with a High Efficiency Particulate Air (HEPA) 
filter; powered air-purifying respirator equipped with tight-fitting 
facepiece (either half-face or full-face) equipped with a High 
Efficiency Particulate Air (HEPA) filter;
    (D) Supplied-air respirator operated in pressure demand or 
continuous flow mode and equipped with a hood or helmet, or tight-
fitting face piece (either half-face or full-face).
    (ii) Hazard communication program. Requirements as specified in 
Sec.  721.72 (a), (b), (c), (d), (e) (concentration set at 1.0 
percent), (f), (g)(1)(ii), (g)(1)(iv), (g)(1)(ix), (g)(2)(ii), 
(g)(2)(iv), and (g)(5).
    (b) * * *
    (1) Recordkeeping. Recordkeeping requirements as specified in Sec.  
721.125 (a), (b), (c), (d), (f), (g), and (h) are applicable to 
manufacturers, importers, and processors of this substance.
