Significant New Use Rule on Certain 
Chemical Substances 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : EPA is proposing significant 
new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for two chemical substances which were the subject of premanufacture notices (PMNs). This action would require persons who intend to manufacture (defined by statute to include import) or process any of the chemical substances for an activity that is designated as a significant new use by this proposed rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA’s evaluation of the intended use within the applicable review period. Manufacture and processing for the significant new use is unable to commence until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required in association with that 
determination. 
DATES : Comments must be received on 
or before September 23, 2016.

SUPPLEMENTARY INFORMATION : 
I. General Information 
A. Does this action apply to me? 
You may be potentially affected by 
this action if you manufacture, process, 
or use the chemical substances contained in this proposed rule. The following list of North American Industrial Classification System (NAICS) codes is not intended to be exhaustive, but rather provides a guide to help readers determine whether this document applies to them. Potentially affected entities may include: 
Manufacturers (including importers) 
or processors of one or more subject chemical substances (NAICS codes 325 and 324110), e.g., chemical 
manufacturing and petroleum refineries. 
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. 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 these SNURs 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 this proposed rule on or after September 23, 2016 are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see § 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 email. 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. 
2. Tips for preparing your comments. 
When preparing and submitting your comments, see the commenting tips at http://www.epa.gov/dockets/ comments.html. 
II. Background A. What action is the agency taking? 
EPA is proposing these SNURs under 
TSCA section 5(a)(2) for two chemical 
substances which were the subject of PMNs P–14–321 and P–14–323. These SNURs would require persons who intend to manufacture or process any of these chemical substances for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity.

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 four bulleted TSCA section 5(a)(2) factors listed in Unit III. 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 or process the chemical substance for that use (15 U.S.C. 2604(a)(1)(B)(i)). TSCA furthermore prohibits such manufacturing or processing from commencing until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required in association with that determination (15 U.S.C. 2604(a)(1)(B)(ii)). As described in Unit V., the general SNUR provisions are found at 40 CFR part 721, subpart A. 
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 § 721.1(c), persons subject to these SNURs must comply with the same SNUN 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 must either determine that the significant new use is not likely to present an unreasonable risk of injury or take such regulatory action as is associated with an alternative determination before the manufacture or processing for the significant new use can commence. If EPA determines that the significant new use is not likely to present an unreasonable risk, EPA is 
required under TSCA section 5(g) to make public, and submit for publication in the Federal Register, a statement of 
EPA’s findings. 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 substances that are the subject of these SNURs, EPA considered relevant information about the toxicity of the chemical substances, likely human exposures and environmental releases associated with possible uses, and the four bulleted TSCA section 5(a)(2) factors listed in this unit. 
IV. Substances Subject to This Proposed 
Rule 
EPA is proposing significant new use 
and recordkeeping requirements for two chemical substances in 40 CFR part 721, subpart E. In this unit, EPA provides the following information for each chemical substance: 
•PMN number. 
•Chemical name (generic name, if 
the specific name is claimed as CBI). 
•Chemical Abstracts Service (CAS) 
Registry number (assigned for non- confidential chemical identities). 
•Tests recommended by EPA to 
provide sufficient information to evaluate the chemical substance (see Unit VII. for more information). 
•CFR citation assigned in the 
regulatory text section of this proposed rule. 
The regulatory text section of this 
proposed rule specifies the activities designated as significant new uses. Certain new uses, including production volume limits (i.e., limits on 
manufacture volume) and other uses designated in this proposed rule, may be claimed as CBI. PMN Number P–14–321 and P–14–323 
Chemical name: 
Hydrochlorofluoropropane and Hydrochlorofluoropropene (generic). 
CAS number: Claimed confidential. 
Effective date of TSCA section 5(e) 
consent order: August 12, 2016. 
Basis for TSCA section 5(e) consent 
order: The PMN states that the generic 
(non-confidential) use of the substances 
will be as site-limited, isolated and recycled intermediates. Based on test data on the PMN substances, EPA identified concerns for acute toxicity including lethality to animals. The Order was issued under TSCA section 5(a)(3)(B)(ii)(I) based on a finding that the substance may present an unreasonable risk of injury to human health. To protect against these risks, the consent order requires: 
1. Submission of certain toxicity 
testing on the PMN substances prior to exceeding the time trigger specified in the consent order of the PMN substances. 
2. Use of impervious gloves and 
protective clothing where dermal exposure is reasonably likely for workers. 
3. Use of respirators with an APF of 
1000, in conjunction with a minimum set of engineering controls to prevent inhalation exposure for workers, or, as an alternative to using respirators, maintain workplace airborne concentrations of the PMN substances at or below a specified New Chemical Exposure Limit (NCEL) of 130 parts per million (ppm) for P–14–321 and 33 parts per billion (ppb) for P–14–323 as an 8-hour time-weighted average, where inhalation exposure is reasonably likely for workers. 
4. Use of engineering controls to limit 
worker exposure and air release of the PMN substances to the environment. 
5. Label containers of the PMN 
substances and provide Safety Data Sheets and worker training. 
6. Manufacture, process and use the 
PMN substances only in an enclosed process. 
7. Use of the PMN substances only as 
chemical intermediates. 
8. No predictable or purposeful 
release of the PMN substances from manufacturing, processing or use into the waters of the United States that result in surface water concentrations exceeding 8 ppb. 
9. Prohibition on the distribution of 
the PMN substances. 
The SNUR designates as a ‘‘significant 
new use’’ the absence of these protective measures. 
Recommended testing: EPA has 
determined that the results of a subacute

inhalation toxicity: 28-day study (OECD 
Test Guideline 412) in three species: Mouse, rat, and rabbit (6 studies total) and a combined repeated dose toxicity study with the reproduction/ developmental toxicity screening test (OECD Test Guideline 422) would help characterize the human health effects of the PMN substances. The submitter has agreed to complete this testing by the production limits identified in the consent order. 
V. Rationale and Objectives of the 
Proposed Rule 
A. Rationale 
During review of the PMNs submitted 
for the chemical substances that are 
subject to these SNURs, 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 the chemical substances. The basis for such findings is outlined in Unit IV. Based on these findings, TSCA section 5(e) consent orders requiring the use of appropriate exposure controls were negotiated with the PMN submitters. The SNUR provisions for these chemical substances are consistent with the provisions of the TSCA section 5(e) consent orders. These SNURs are promulgated pursuant to § 721.160 (see Unit VI.). 
B. Objectives 
EPA is proposing these SNURs for 
specific chemical substances which 
have 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 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 or processing a listed chemical substance for the described significant new use. 
•EPA would be able to either 
determine that the prospective manufacture or processing is not likely to present an unreasonable risk, or to take necessary regulatory action associated with any other determination, before the described significant new use of the chemical substance occurs. 
Issuance of a SNUR for a chemical 
substance does not signify that the chemical substance is listed on the TSCA Chemical Substance Inventory 
(TSCA Inventory). Guidance on how to determine if a chemical substance is on the TSCA Inventory is available on the Internet at https://www.epa.gov/tsca- inventory. 
VI. Applicability of the Proposed Rule 
to Uses Occurring Before the Effective Date of the Final Rule 
To establish a significant new use, 
EPA must determine that the use is not ongoing. The chemical substances subject to this proposed rule have undergone premanufacture review. In cases where EPA has not received a notice of commencement (NOC) and the chemical substance has not been added to the TSCA Inventory, no person may commence such activities without first submitting a PMN. Therefore, for chemical substances for which an NOC has not been submitted EPA concludes that the designated significant new uses are not ongoing. 
When chemical substances identified 
in this proposed rule are added to the TSCA Inventory, EPA recognizes that, before the rule is effective, other persons might engage in a use that has been identified as a significant new use. The identities of the two chemical substances subject to this proposed rule have been claimed as confidential and EPA has received no post-PMN bona fide submissions (per §§ 720.25 and 
721.11). Based on this, the Agency believes that it is highly unlikely that any of the significant new uses described in the regulatory text of this proposed rule are ongoing. 
Therefore, EPA designates August 15, 
2016 (the date of public release/web 
posting of this proposal) as the cutoff date for determining whether the new use is ongoing. This designation varies slightly from EPA’s past practice of designating the date of Federal Register publication as the date for making this determination. The objective of EPA’s approach has been to ensure that a person could not defeat a SNUR by initiating a significant new use before the effective date of the final rule. In developing this proposal, EPA has recognized that, given EPA’s practice of now posting proposed rules on its Web site a week or more in advance of Federal Register publication, this objective could be thwarted even before that publication. Thus, EPA has slightly modified its approach in this rulemaking and plans to follow this modified approach in future significant new use rulemakings. 
Persons who begin commercial 
manufacture or processing of the chemical substances for a significant new use identified as of August 15, 2016 would have to cease any such activity 
upon the effective date of the final rule. To resume their activities, these persons would have to first comply with all applicable SNUR notification requirements and wait until all TSCA prerequisites for the commencement of manufacture or processing have been satisfied. If such a person met the conditions of advance compliance under § 721.45(h), the person would be considered exempt from the requirements of the SNUR. Consult the Federal Register document of April 24, 1990 (55 FR 17376) for a more detailed discussion of the cutoff date for ongoing uses. 
VII. Test Data and Other Information 
EPA recognizes that TSCA section 5 
does not require developing new 
information (e.g., generating test data) 
before submission of a SNUN. There is an exception: 
1. Development of test data is 
required where the chemical substance subject to the SNUR is also subject to a test rule, order, or consent agreement 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 test rule, order, or 
consent agreement under TSCA section 
4 covering the chemical substance, persons are required only to submit information in their possession or control and to describe any other information known to or reasonably ascertainable by them (see 40 CFR 720.50). However, upon review of PMNs and SNUNs, the Agency has the authority to require appropriate testing. 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 OCSPP test guidelines referenced in this document electronically, please go to http://www.epa.gov/ocspp and select ‘‘Test 
Guidelines for Pesticides and Toxic Substances.’’ 
The recommended tests specified in 
Unit IV. may not be the only means of addressing the potential risks of the chemical substance. However, submitting a SNUN that does not itself include information sufficient to permit a reasoned evaluation may increase the likelihood that EPA will either respond with a determination that the information available to the Agency is insufficient to permit a reasoned evaluation of the health and environmental effects of the significant 
VerDate Sep<11>2014 19:02 Aug 23, 2016 Jkt 238001 PO 00000 Frm 00040 Fmt 4702 Sfmt 4702 E:\FR\FM\24AUP1.SGM 24AUP1mstockstill on DSK3G9T082PROD with PROPOSALS57849 Federal Register / Vol. 81, No. 164 / Wednesday, August 24, 2016 / Proposed Rules 
new use or, alternatively, that in the 
absence of sufficient information, the manufacture, processing, distribution in commerce, use, or disposal of the chemical substance may present an unreasonable risk of injury. 
SNUN submitters should be aware 
that EPA will be better able to evaluate SNUNs and define the terms of any potentially necessary controls if the submitter provides detailed information on: 
•Human exposure and 
environmental release 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 compared to risks posed by potential substitutes. 
VIII. SNUN Submissions 
EPA recommends that submitters 
consult with the Agency prior to 
submitting a SNUN to discuss what information may be useful in evaluating a significant new use. Discussions with the Agency prior to submission can afford ample time to conduct any tests that might be helpful in evaluating risks posed by the substance. According to § 721.1(c), persons submitting a SNUN must comply with the same notification requirements and EPA regulatory procedures as persons submitting a PMN, including submission of test data on health and environmental effects as described in 40 CFR 720.50. SNUNs must be submitted on EPA Form No. 7710–25, generated using e-PMN software, and submitted to the Agency in accordance with the procedures set forth in 40 CFR 720.40 and 721.25. E– PMN software is available electronically at https://www.epa.gov/reviewing-new- 
chemicals-under-toxic-substances- control-act-tsca/how-submit-e-pmn. 
IX. Scientific Standards, Evidence, and 
Available Information 
EPA has used scientific information, 
technical procedures, measures, methods, protocols, methodologies, and models consistent with the risk assessment documents included in the public docket. 
The clarity and completeness of the 
data, assumptions, methods, quality assurance, and analyses employed in EPA’s decision are documented, as applicable and to the extent necessary for purposes of this proposed significant new use rule, in Unit II and in the documents noted above. EPA recognizes, based on the available information, that there is variability and uncertainty in whether any particular significant new use would actually present an unreasonable risk. For precisely this reason, it is appropriate to secure a future notice and review process for these uses, at such time as they are known more definitely. The extent to which the various information, procedures, measures, methods, protocols, methodologies or models used in EPA’s decision have been subject to independent verification or peer review is adequate to justify their use, collectively, in the record for a significant new use rule. 
X. Economic Analysis 
EPA has evaluated the potential costs 
of establishing SNUN requirements for 
potential manufacturers and processors of the chemical substances subject to this proposed rule, during the development of the direct final rule. EPA’s complete economic analysis is available in the docket under docket ID number EPA–HQ–OPPT–2016–0491. 
XI. Statutory and Executive Order 
Reviews 
A. Executive Order 12866 
This proposed rule would establish 
SNURs for two chemical substances that 
were the subject of PMNs. 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 (PRA) 
According to 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 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 proposed rule have already been approved by OMB pursuant to PRA under OMB control number 2070–0012 (EPA ICR No. 574). This proposed rule 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 (RFA) 
On February 18, 2012, EPA certified 
pursuant to RFA section 605(b) (5 U.S.C. 
601 et seq.), that promulgation of a 
SNUR does not have a significant economic impact on a substantial number of small entities where the following are true: 
1. A significant number of SNUNs 
would not be submitted by small entities in response to the SNUR. 
2. The SNUR submitted by any small 
entity would not cost significantly more than $8,300. 
A copy of that certification is 
available in the docket for this proposed rule. 
This proposed rule is within the 
scope of the February 18, 2012 certification. Based on the Economic Analysis discussed in Unit IX. and EPA’s experience promulgating SNURs (discussed in the certification), EPA believes that the following are true: 
•A significant number of SNUNs 
would not be submitted by small entities in response to the SNUR. 
•Submission of the SNUN would not 
cost any small entity significantly more than $8,300. 
Therefore, the promulgation of the 
SNUR would not have a significant economic impact on a substantial number of small entities. 
D. Unfunded Mandates Reform Act 
(UMRA) 
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 effect on small governments subject to the requirements of UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.).

E. Executive Order 13132 
This proposed rule 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 proposed rule 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 proposed rule 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 proposed rule is not expected to affect energy supply, distribution, or use and because this proposed rule is not a significant regulatory action under Executive Order 12866. 
I. National Technology Transfer and 
Advancement Act (NTTAA) 
In addition, since this proposed rule 
would not involve any technical standards, NTTAA section 12(d) (15 U.S.C. 272 note), would not apply to this proposed rule. 
J. Executive Order 12898 
This proposed rule 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).

significant new uses subject to reporting. 
(1) The chemical substances identified generically as hydrochlorofluoropropane and hydrochlorofluoropropene (generic) (PMNs P–14–321 and P–14–323) are subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section. 
(2) The significant new uses are: 
(i) Protection in the workplace. 
Requirements as specified in 
§ 721.63(a)(1), (a)(2)(i), (a)(3), (a)(4), (a)(6)(v), (a)(6)(vi), and (c). When determining which persons are reasonably likely to be exposed as required for § 721.63(a)(4), engineering control measures (e.g., enclosure or 
confinement of the operation, general and local ventilation) or administrative control measures (e.g., workplace 
policies and procedures) shall be considered and implemented to prevent exposure, where feasible. The following National Institute for Occupational Safety and Health (NIOSH)-certified respirators with an Assigned Protection Factor (APF) of at least 1000 meet the requirements of § 721.63(a)(4): 
(A) Any NIOSH-certified powered air 
purifying full facepiece respirator equipped with appropriate gas/vapor (acid gas, organic vapor, or substance specific) cartridges. 
(B) Any NIOSH-certified powered air- 
purifying respirator equipped with a hood or helmet and appropriate gas/ vapor (acid gas, organic vapor, or substance specific) cartridges with evidence demonstrating protection level of 1,000 or greater. (Note: OSHA has assigned APFs of 1000 for certain types of hoods and helmets with powered air purifying respirators (PAPRs) or supplied air respirators (SARs) where the manufacturer can demonstrate adequate air flows to maintain positive pressure inside the hood or helmet in normal working conditions. However, the employer must have evidence provided by the respirator manufacturer that the testing of these respirators demonstrates performance at a level of protection of 1,000 or greater to receive an APF of 1,000. This level of performance can best be demonstrated by performing a Workplace Protection Factor (WPF) or Simulated Workplace Protection Factor (SWPF) study or equivalent testing. Without testing data that demonstrates a level of protection of 1,000 or greater, all PAPRs and SARs with helmets/hoods are to be treated as loose-fitting facepiece respirators, and receive an APF of 25.) 
(C) Any NIOSH-certified continuous 
flow supplied-air respirator equipped with a full facepiece. 
(D) Any NIOSH-certified continuous 
flow supplied-air respirator equipped with a hood or helmet with evidence demonstrating protection level of 1,000 or greater. (See Note under (II), above) 
(E) Any NIOSH-certified pressure- 
demand or other positive pressure mode supplied-air respirator equipped with a full facepiece. 
(1) As an alternative to the respiratory 
requirements listed here, a manufacturer or processor may choose to follow the New Chemical Exposure Limit (NCEL) provisions listed in the TSCA section 5(e) consent order for this substance. The NCEL is 130 parts per million for P–14–321 and 33 parts per billion for P– 14–323 as an 8-hour time weighted average (TWA) verified by actual monitoring data. 
(ii) Hazard communication program. 
Requirements as specified in § 721.72(a), (b), (c), (d), (f), (g)(1)(i), (g)(1)(fatal if inhaled), (g)(2)(ii), (g)(2)(iv), (g)(2)(v), and (g)(2)(do not release to water). 
(ii) Industrial, commercial, and 
consumer activities. Requirements as specified in § 721.80(a) and (g). It is a significant new use to manufacture, process, or use the PMN substances without the engineering controls described in the consent order to prevent worker and environmental exposures. It is a significant new use to manufacture the PMN substances for more than one year. 
(iii) Release to water. Requirements as 
specified in § 721.90(a)(4), (b)(4), and (c)(4) (N=8).
