the Initiation of a Proceeding to Consider Proposed 
Changes in Analytical Principles (Proposal Eight), October 5, 2018 (Petition).

Determination Report, March 29, 2018, at 26. III. Notice and Comment 
IV. Ordering Paragraphs 
I. Introduction 
On October 5, 2018, the Postal Service 
filed a petition pursuant to 39 CFR 
3050.11 requesting that the Commission initiate a rulemaking proceeding to consider changes to analytical principles relating to periodic reports.
1 
The Petition identifies the proposed analytical changes filed in this docket as Proposal Eight. 
II. Proposal Eight 
Background. The Postal Service seeks 
to modify the modeling methodology in 
First-Class Mail and Marketing Mail Letter cost models to reflect current operational flows. Petition, Proposal Eight at 1. The Postal Service states that Proposal Eight relates to the Commission’s directive in the FY 2017 Annual Compliance Determination Report for the Postal Service to ‘‘provide a plan to move the passthrough toward 100 percent’’ for USPS Marketing Mail Automation Letters Barcoding.
2The 
Postal Service states Proposal Eight ‘‘aligns the barcode cost avoidance and the associated passthrough with the Commission’s directive.’’ Id. 
The Postal Service states that it 
developed its current mail processing letter cost models when cancellation equipment had limited functionality. Id. at 2. The outgoing primary scheme could not isolate mail for all automated area distribution centers (AADCs), and mail for low volume AADCs flowed to the outgoing secondary scheme. Id. 
The Postal Service states that due to 
advances in Optical Character Recognition (OCR) technology, its Advanced Facer Canceller System (AFCS) is now able to read addresses and isolate locally-processed mail from mail destinating in the service territory of other processing facilities. Id. This 
capability eliminated the need for local separations on outgoing primary schemes, or the processing of pre- barcoded mail on the outgoing secondary scheme. Id. The Postal 
Service states the result is an increased quantity of mail processed on the outgoing primary scheme. Id. at 2–3. 
Proposal. The Postal Service proposes 
three operational and methodological changes: (1) Modification of models to reflect current operational flows; (2) correction of the exclusion of mechanical rejects from the Input Sub System (ISS); and (3) removal of the 
conflation of differential flows between Output Sub System (OSS) operations and automation barcode sortation (BCS) operations in the Marketing Mail Letters cost model. Id. at 3. 
The Postal Service states that 
modification 1 aligns the current operational flows of automation pre- barcoded Mixed AADC (MAADC) mail with modeled automation mail. Id. at 4. 
The modification changes the inflow of 10,000 pieces of modeled mail from the outgoing secondary entry point. Id. The 
Postal Service states that the ‘‘modification directly impacts only the Automation MAADC Presort Letters and Cards categories.’’ Id. 
The Postal Service states that the 
current letter models do not account for mechanical rejects that flow to manual operations. Id. The Postal Service states 
that the delivery BCS (DBCS) Input Output Sub System (DIOSS) reject rate is composed of the OSS rate of rejects flowing to manual operations. Id. Modification 2 ‘‘corrects the DIOSS operations’ treatment of rejects to that of traditional OSS/ISS operations for treatment of pieces flowing to manual operations and to OSS operations.’’ Id. 
The Postal Service suggests that the 
current Marketing Mail Letters cost 
model, calculating the barcode cost avoidance as the difference between modeled (Non-Automation) Machinable MAADC letters and Automation MAADC letters, ‘‘conflates the value of the barcode with intrinsic differences between non-barcoded and automation mail.’’ Id. at 5. Modification 3 corrects 
the model for machinable MAADC mail by using the same down flow densities as automation MAADC mail, ‘‘thereby accurately estimating the value of a barcode when used as a benchmark.’’ Id. The Postal Service states that this modification applies only to Marketing Mail Letters. Id. at 6. 
Rationale and impact. The Postal 
Service states that it intends for the proposal to modify the letter processing models to reflect ‘‘current operational reality.’’ Id. at 1. The Postal Service 
states that the proposal would increase the barcode cost avoidance of Marketing Mail Automation MAADC letters from $0.001 to $0.006, while reducing the passthrough from 1300 percent to 217 percent. Id. at 6. The Postal Service 
provides the change in mail processing unit costs for Marketing Mail Letters and First-Class Mail Letters and Cards. Id. at 7–8. 
III. Notice and Comment

No. RM2019–1 for consideration of matters raised by the Petition. More information on the Petition may be accessed via the Commission’s website at http://www.prc.gov. Interested

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 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 proposed SNURs would need to certify their compliance with the SNUR requirements should these proposed rules be finalized. The EPA policy in support of import certification appears at 40 CFR part 707, subpart B. In addition, pursuant to 40 CFR 721.20, any persons who export or intend to export a chemical substance that is the subject of this proposed rule on or after November 15, 2018 are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) 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 CBI 
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 13 chemical 
substances which were the subjects of PMNs P–16–192, P–16–354 and P–16– 355, P–16–380 through P–16–385, P– 
16–483 and P–16–484, P–16–575, and P–16–581. These proposed 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. 
The record for the proposed SNURs 
on these chemicals was established as docket EPA–HQ–OPPT–2017–0575. That record includes information considered by the Agency in developing these proposed SNURs. 
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)(i) (15 U.S.C. 2604(a)(1)(B)(i)) 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. TSCA prohibits such manufacturing or processing from commencing until EPA has conducted a review of the SNUN, 
made an appropriate determination on the SNUN, 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 rule. Provisions relating to user fees appear at 40 CFR part 700. Pursuant 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) (15 U.S.C. 2604(a)(1)(A)). In particular, these requirements include the information submission requirements of TSCA sections 5(b) and 5(d)(1) (15 U.S.C. 2604(b) and 2604(d)(1)), the exemptions authorized by TSCA sections 5(h)(1), 5(h)(2), 5(h)(3), and 5(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 authorizes EPA to consider any other relevant factors. 
To determine what would constitute 
significant new uses for the chemical substances that are the subject of these SNURs, EPA considered relevant information about the toxicity of the chemical substances, and potential human exposures and environmental releases that may be associated with the conditions of use of the substances, in the context of 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 13 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 (if assigned for non- confidential chemical identities). 
•Basis for the SNUR. 
•Information identified by EPA that 
would help characterize the potential health and/or environmental effects of 
the chemical substances if a manufacturer or processor is considering submitting a SNUN for a significant new use designated by the SNUR. 
This information may include testing 
not required to be conducted but which would help characterize the potential health and/or environmental effects of the PMN substance. Any recommendation for information identified by EPA was made based on EPA’s consideration of available 
screening-level data, if any, as well as other available information on appropriate testing for the chemical substance. Further, any such testing identified by EPA that includes testing on vertebrates was made after consideration of available toxicity information, computational toxicology and bioinformatics, and high- throughput screening methods and their prediction models. EPA also recognizes that whether testing/further information is needed will depend on the specific exposure and use scenario in the SNUN. EPA encourages all SNUN submitters to contact EPA to discuss any potential future testing. See Unit VII. for more information. 
•CFR citation assigned in the 
regulatory text section of these proposed rules. 
The regulatory text section of these 
proposed rules specifies the activities designated as significant new uses. Certain new uses, including production volume limits and other uses designated in the proposed rules, may be claimed as CBI. 
The chemical substances that are the 
subject of these proposed SNURs are undergoing premanufacture review. EPA has initially determined under TSCA section 5(a)(2), 15 U.S.C. 2604(a)(2), that certain changes from the conditions of use described in the PMNs could result in changes in the type or form of exposure to the chemical substances and/or increased exposures to the chemical substances and/or changes in the reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of the chemical substances. Consequently, EPA is proposing to designate these changes as significant new uses. 
PMN Number: P–16–192 
Chemical Name: Silanized 
amorphous silica (generic). 
CAS Number: Not available. 
Basis for action: The PMN states that 
the use of the substance will be as a 
reinforcing filler for the production of rubber goods. Based on test data for crystalline silica, EPA identified concerns for lung effects if the chemical substance is not used following the limitations noted below. The conditions of use of the PMN substance as described in the PMN include the following protective measures: 
1. Manufacture of the PMN substance 
in an amorphous form. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of this protective measure. 
Potentially useful information: EPA 
has determined that certain information about the physical-chemical properties of the PMN substance may be potentially useful if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this proposed SNUR. EPA has determined that information about the physical form, particle size, and water solubility would help characterize the potential health effects of the PMN substance. 
CFR citation: 40 CFR 721.11182. 
PMN Numbers: P–16–354 and P–16–355 
Chemical name: Esteramine (generic). 
CAS number: Not available. Basis for action: The PMNs state that 
the generic (non-confidential) use of the 
substances will be as a chemical intermediate. Based on the physical/ chemical properties of the PMN substances and Structure Analysis Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for irritation and developmental/reproductive toxicity, and aquatic toxicity at surface water concentrations exceeding 1 part per billion (ppb), if the chemical substances are not used following the limitations noted below. The conditions of use of the PMN substances as described in the PMNs include the following protective measures: 
1. No release of a manufacturing, 
processing, or use stream associated with any use of the substances, other than the confidential chemical intermediate use described in the PMNs, into the waters of the United States exceeding a surface water concentration of 1 ppb; and 
2. No manufacturing, processing or 
use of the PMN substances resulting in inhalation exposures to the substances. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of these protective measures. 
Potentially useful information: EPA 
has determined that certain information about the aquatic and human health toxicity of the PMN substances may be potentially useful to characterize the health and environmental effects of the PMN substances if a manufacturer or

acetates (salts), (generic) (P–16–383), propanoic acid, 2-hydroxy-, compds. with hydrolyzed bisphenol A- epichlorohydrin-polyethylene glycol ether with bisphenol A (2:1) polymer- N1-(1,3-dimethylbutylidene)-N2-[2-[(1, 3-dimethylbutylidene)amino]ethyl]-1,2- ethanediamine-dialdehyde-2- (methylamino)ethanol reaction products formates (salts), (generic) (P–16–384), formic acid, compds. with hydrolyzed bisphenol A-epichlorohydrin- polyethylene glycol ether with bisphenol A (2:1) polymer-N1-(1,3- dimethylbutylidene)-N2-[2-[(1, 3- dimethylbutylidene)amino]ethyl]-1,2- ethanediamine-dialdehyde-2- (methylamino)ethanol reaction products sulfamates (salts), (generic) (P–16–385). 
CAS Numbers: Not available. Basis for action: The PMNs state that 
the generic (non-confidential) use of the 
substances will be as a component of an electrocoat resin. Based on the physical/ chemical properties of the PMN 
substances and test data on analogous substances, EPA has identified concerns for lung effects and toxicity to aquatic organisms at concentrations that exceed 16 ppb if the chemical substances are not used following the limitations noted below. The conditions of use of the PMN substances as described in the PMNs include the following protective measures: 
1. No manufacturing, processing or 
use of the PMN substances resulting in inhalation exposures to the substances; and 
2. No release of a manufacturing, 
processing, or use stream associated with any use of the substances exceeding a surface water concentration of 16 ppb. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of these protective measures. 
Potentially useful information: EPA 
has determined that certain information about the health and environmental effects of the PMN substances may be potentially useful if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this proposed SNUR. EPA has determined that the results of specific target organ, pulmonary, and acute aquatic toxicity testing would help characterize the potential health and environmental effects of the PMN substances.

heteroaromatics, (generic) (P–16–483) and Inorganic acids, metal salts, compds. with substituted aromatic heterocycle, (generic) (P–16–484). 
CAS numbers: Not available. 
Basis for action: The PMNs state that 
the generic (non-confidential) use of P– 
16–483 will be as a plastic additive and the generic (non-confidential) use of P– 16–484 will be as a chemical intermediate. Based on test data submitted on P–16–483 and data for analogous compounds, EPA has identified concerns for irritation, specific organ effects, and aquatic toxicity if the chemical is not used following the limitations noted below. The conditions of use of the PMN substances as described in the PMNs include the following protective measures: 
1. No use of the substances other than 
the confidential use described in the PMNs; 
2. No release of a manufacturing, 
processing, or use stream associated with any use of the substances exceeding a surface water concentration of 34 ppb; and 
3. No manufacturing, processing or 
use of the PMN substances without the engineering controls described in the PMNs to limit exposure to dust. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of these protective measures. 
Potentially useful information: EPA 
has determined that certain information about the human health and environmental toxicity of the PMN substances may be potentially useful to characterize the effects of the PMN substances if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this proposed SNUR. EPA has determined that the results of aquatic toxicity and specific organ toxicity and aquatic toxicity testing would help characterize the potential health and environmental effects of the PMN substances.

with particle size less than 10 micrometers. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of these protective measures. 
Potentially useful information: EPA 
has determined that certain information about the toxicity of the PMN substance may be potentially useful to characterize the health effects of the PMN substance if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this proposed SNUR. EPA has determined that the results of pulmonary effects toxicity testing of the PMN substance may be potentially useful in characterizing the health effects of the PMN substance. 
CFR citation: 40 CFR 721.11193. 
V. Rationale and Objectives of the Proposed Rule 
A. Rationale 
During review of the PMNs submitted 
for the chemical substances that are the 
subject of these proposed SNURs and as further discussed in Unit IV, EPA identified certain reasonably foreseen changes from the conditions of use identified in the PMNs and determined that those changes could result in changes in the type or form of exposure to the chemical substances and/or increased exposures to the chemical substances and/or changes in the reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of the chemical substances. B. Objectives 
EPA is proposing SNURs for 13 
specific chemical substances which are undergoing premanufacture review because the Agency wants to achieve the following objectives with regard to the significant new uses that would be designated in this proposed rule: 
•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 obligated to make a 
determination under TSCA section 5(a)(3) regarding the use described in the SNUN, under the conditions of use. The Agency will either determine under section 5(a)(3)(C) that the significant new use is not likely to present an unreasonable risk, including an unreasonable risk to a potentially exposed or susceptible subpopulation identified as relevant by the Administrator under the conditions of use, or make a determination under section 5(a)(3)(A) or (B) and take the required regulatory action associated with the determination, before manufacture or processing for the significant new use of the chemical substance can occur. 
Issuance of a proposed 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/ existingchemicals/pubs/tscainventory/ index.html. 
VI. Applicability of the Proposed Rules 
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 were undergoing premanufacture review at the time of signature of this proposed rule and were not on the TSCA Inventory. 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 the chemical substances subject to this proposed SNUR, EPA concludes that the proposed significant new uses are not ongoing. 
EPA designates October 10, 2018, as 
the cutoff date for determining whether the new use is ongoing. The objective of EPA’s approach is to ensure that a person cannot defeat a SNUR by initiating a significant new use before 
the effective date of the final rule. 
Persons who begin commercial 
manufacture or processing of the chemical substances for a significant new use identified on or after that date 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 EPA would have to take action under section 5 allowing manufacture or processing to proceed. 
VII. Development and Submission of 
Information 
EPA recognizes that TSCA section 5 
does not require development of any particular new information (e.g., generating test data) before submission of a SNUN. There is an exception: If a person is required to submit information for a chemical substance pursuant to a rule, order or consent agreement under TSCA section 4 (15 U.S.C. 2603), then TSCA section 5(b)(1)(A) (15 U.S.C. 2604(b)(1)(A)) requires such information to be submitted to EPA at the time of submission of the SNUN. 
In the absence of a 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 § 720.50). However, upon review of PMNs and SNUNs, the Agency has the authority to require appropriate testing. Unit IV. lists potentially useful information for all 
SNURs listed here. Descriptions are provided for informational purposes. The potentially useful information identified in Unit IV. will be useful to EPA’s evaluation in the event that someone submits a SNUN for the significant new use. Companies who are considering submitting a SNUN are encouraged, but not required, to develop the information on the substance, which may assist with EPA’s analysis of the SNUN. 
EPA strongly encourages persons, 
before performing any testing, to consult with the Agency pertaining to protocol selection. Furthermore, pursuant to TSCA section 4(h), which pertains to reduction of testing in vertebrate animals, EPA encourages consultation with the Agency on the use of alternative test methods and strategies (also called New Approach Methodologies, or NAMs), if available, to generate the recommended test data. EPA encourages dialog with Agency representatives to help determine how best the submitter can meet both the

data needs and the objective of TSCA 
section 4(h). 
The potentially useful information 
described in Unit IV. may not be the only means of providing information to evaluate the chemical substance associated with the significant new uses. However, submitting a SNUN without any test data may increase the likelihood that EPA will take action under TSCA section 5(e) or 5(f). 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 substances. 
•Information on risks posed by the 
chemical substances compared to risks posed by potential substitutes. 
VIII. SNUN Submissions 
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 § 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 § 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. 
IX. 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. EPA’s complete economic analysis is available in the docket under docket ID number EPA– HQ–OPPT–2017–0575. 
X. Statutory and Executive Order 
Reviews 
A. Executive Order 12866 
This proposed rule would establish 
SNURs for 13 new 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 action have already been approved by OMB pursuant to PRA under OMB control number 2070–0012 (EPA ICR No. 574). This action does 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. 
605(b)), 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 SNUN submitted by any small 
entity would not cost significantly more than $9,816. 
A copy of that certification is 
available in the docket for this action. 
This proposed rule is within the 
scope of the February 18, 2012 certification. Based on the Economic Analysis discussed in Unit XI. 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 $9.816. 
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 will be impacted by this proposed rule. As such, EPA has determined that this proposed rule does 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. 1502, 1503, 1504, or 1505 et seq.). 
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 does 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 (NTTAA) 
In addition, since this action does not 
involve any technical standards, NTTAA § 12(d) (Pub. L. 104–113, 12(d)), 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).
