Significant New Use Rules on Certain 
Chemical Substances (21–2.B) 
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 chemical substances which are the subject of premanufacture notices (PMNs). This action would require persons to notify EPA at least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use by this proposed rule. This action would further require that persons not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice (SNUN), and EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken any risk management actions as are required as a result of that determination. 
DATES : Comments must be received on 
or before June 1, 2021.

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 provisions. This action may also affect certain entities through pre-existing import certification and export notification rules under TSCA, which would include 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 June 1, 2021 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 https://www.epa.gov/dockets/ commenting-epa-dockets. 
II. Background A. What action is the Agency taking? 
EPA is proposing these SNURs under 
TSCA section 5(a)(2) for chemical 
substances which are the subjects of PMNs P–19–82, P–20–76, and P–20–94. 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 these proposed SNURs, 
identified as docket ID number EPA– HQ–OPPT–2020–0581, includes information considered by the Agency in developing these proposed SNURs. 
B. What is the Agency’s authority for 
taking this action? 
TSCA section 5(a)(2) (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 TSCA section 5(a)(2) factors listed in Unit III. 
C. Do the SNUR general provisions 
apply? 
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 
VerDate Sep<11>2014 16:45 Apr 29, 2021 Jkt 253001 PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 E:\FR\FM\30APP1.SGM 30APP1jbell on DSKJLSW7X2PROD with PROPOSALS22925 Federal Register / Vol. 86, No. 82 / Friday, April 30, 2021 / Proposed Rules 
40 CFR 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 use is not likely to present an unreasonable risk of injury under the conditions of use for the chemical substance 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 chemical substance 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 
TSCA section 5(a)(2) 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 determining 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, and potential human exposures and environmental releases that may be associated with the substances, in the context of the four bulleted TSCA section 5(a)(2) factors listed in this unit. During its review of these chemicals, EPA identified certain conditions of use that are not intended by the submitters, but reasonably foreseen to occur. EPA is proposing to designate those reasonably foreseen conditions of use as well as certain other circumstances of use as significant new uses. 
IV. Substances Subject to This Proposed 
Rule 
EPA is proposing significant new use 
and recordkeeping requirements be added to 40 CFR part 721, subpart E for the chemical substances identified in this unit. For each chemical substance, EPA provides the following information in this unit: 
•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. 
•Potentially useful 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. In addition to those conditions of use intended by the submitter, EPA has identified certain other reasonably foreseen conditions of use. EPA has preliminarily determined that the chemicals under their intended conditions of use are not likely to present an unreasonable risk. However, EPA has not assessed risks associated with the reasonably foreseen conditions of use for these chemicals. EPA is proposing to designate these reasonably foreseen conditions of use and other circumstances of use as significant new uses. As a result, those significant new uses cannot occur without first going through a separate, subsequent EPA review and determination process associated with a SNUN. 
The substances subject to these 
proposed rules are as follows: 
PMN Number: P–19–82. 
Chemical name: Heptanal, 6-hydroxy- 
2,6-dimethyl-. 
CAS number: 62439–42–3. Basis for action: The PMN states that 
the use of the substance will be as a 
fragrance for scented papers, candles, detergents, cleaners, etc. and for non- TSCA fragrance applications. Based on the physical/chemical properties of the substance, test data on the substance, and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for aquatic toxicity, eye irritation, reproductive toxicity, skin sensitization, and specific target organ toxicity if the chemical is not used following the limitations noted. This proposed SNUR designates the following as ‘‘significant new uses’’ requiring further review by EPA: 
•Processing the PMN substance to a 
concentration of greater than or equal to 1.0% in the final end use formulation. 
•Release of the PMN substance 
resulting in surface water concentrations that exceed 14 ppb. 
Potentially useful information: EPA 
has determined that certain information about the effects 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 the results of aquatic toxicity, developmental toxicity, eye irritation/corrosion, and specific target organ toxicity testing would help characterize the potential environmental and health effects of the PMN substance. 
CFR citation: 40 CFR 721.11568. 
PMN Number: P–20–76. 
Chemical name: Glycine, reaction 
products with sodium O-iso-Pr carbonodithioate, sodium salts. 
CAS number: 2205080–23–3. Basis for action: The PMN states that 
the generic use of the substance will be as a mining chemical. Based on the physical/chemical properties of the substance, test data on the substance, and SAR analysis of test data on analogous substances, EPA has identified concerns for aquatic toxicity, carcinogenicity, genetic toxicity, reproductive toxicity, serious eye damage, skin corrosion, skin sensitization, and specific target organ toxicity if the chemical is not used following the limitations noted. This proposed SNUR designates the following as ‘‘significant new uses’’ requiring further review by EPA: 
•Domestic manufacture of the PMN 
substance. 
•Release of the PMN substance 
resulting in surface water concentrations that exceed 21 ppb. 
Potentially useful information: EPA 
has determined that certain information about the effects 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 the results of aquatic toxicity, carcinogenicity, eye irritation/corrosion, genetic toxicity, reproductive toxicity, skin sensitization, and specific target organ toxicity testing

would help characterize the potential 
environmental and health effects of the PMN substance. 
CFR citation: 40 CFR 721.11569. 
PMN Number: P–20–94. 
Chemical name: Alkanedioic acid, 
polymer with tri-alkyl- 
isocyanatocarbomonocycle, dialkylglycols, ester with 2,3- dihydroxypropyl alkyl ester, 2- hydroxyethyl methacrylate-blocked (generic). 
CAS number: Not Available. 
Basis for action: The PMN states that 
the use of the substance will be as a 
formulation component in UV/EB coatings, inks, 3D printing/ stereolithography/additive manufacturing, and adhesive manufacturing. Based on the physical/ chemical properties of the substance and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for eye irritation, skin irritation, and skin sensitization, if the chemical is not used following the limitations noted. This proposed SNUR designates the following as ‘‘significant new uses’’ requiring further review by EPA: 
•Use without personal protective 
equipment involving a National Institute for Occupational Safety and Health (NIOSH)-certified respirator with an Assigned Protection Factor (APF) of at least 50 (or 1,000 for spray applications), unless the substance was manufactured with no greater than 3.5% acrylate feedstock by weight and any residual isocyanate in the substance is present at no greater than 0.1% by weight. 
•Use of the PMN substance in a 
consumer product. 
Potentially useful information: EPA 
has determined that certain information about the effects 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 the results of occupational exposure monitoring would help characterize the potential effects of the PMN substance. 
CFR citation: 40 CFR 721.11570. 
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 other reasonably foreseen conditions of use, in addition to those conditions of use intended by the submitter. EPA has preliminarily 
determined that the chemical under the intended conditions of use is not likely to present an unreasonable risk. However, EPA has not assessed risks associated with the reasonably foreseen conditions of use. EPA is proposing to designate these conditions of use as well as certain other circumstances of use as 
significant new uses. As a result, those significant new uses cannot occur without going through a separate, subsequent EPA review and determination process associated with a SNUN. 
B. Objectives 
EPA is proposing these SNURs 
because the Agency wants: 
•To 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. 
•To 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 TSCA section 5(a)(3)(C) that the chemical, under the conditions of 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 TSCA 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. 
•To be able to complete its review 
and determination on each of the PMN substances, while deferring analysis on the significant new uses proposed in these rules unless and until the Agency receives a SNUN. 
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 https://www.epa.gov/tsca- inventory. 
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 these proposed SNURs, EPA concludes that the proposed significant new uses are not ongoing. 
EPA designates December 4, 2020 
(date of web posting of this proposed rule) 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. In developing this proposed rule, EPA has recognized that, given EPA’s general practice of posting proposed rules on its website a week or more in advance of Federal Register publication, this objective could be thwarted even before Federal Register publication of the proposed rule. 
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, then TSCA section 5(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 40 CFR 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 sections 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. 
VIII. SNUN Submissions 
According to 40 CFR 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. 
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 for this rulemaking. 
X. Statutory and Executive Order 
Reviews 
Additional information about these 
statutes and Executive orders can be found at https://www.epa.gov/laws- regulations-and-executive-orders. 
A. Executive Order 12866: Regulatory 
Planning and Review and Executive Order 13563: Improving Regulations and Regulatory Review 
This action proposes to establish 
SNURs for 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011). 
B. Paperwork Reduction Act (PRA) 
According to the 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, Regulatory Support Division, Office of Mission Support (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) 
Pursuant to section 605(b) of the RFA, 
5 U.S.C. 601 et seq., I hereby certify that 
promulgation of this proposed SNUR would not have a significant adverse economic impact on a substantial number of small entities. 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 final 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 small number of notices per year. For example, the number of SNUNs received was seven in Federal fiscal year (FY) 2013, 13 in FY2014, six in FY2015, 12 in FY2016, 13 in FY2017, and 11 in FY2018, only a fraction of 
these were from small businesses. In addition, the Agency currently offers relief to qualifying small businesses by reducing the SNUN submission fee from $16,000 to $2,800. This lower fee reduces the total reporting and recordkeeping of cost of submitting a SNUN to about $10,116 for qualifying small firms. Therefore, the potential economic impacts of complying with this proposed SNUR are not expected to be significant or adversely impact a substantial number of small entities. In a SNUR that published in the Federal Register of June 2, 1997 (62 FR 29684) 
(FRL–5597–1), the Agency presented its general determination that final SNURs are not expected to have a significant economic impact on a substantial number of small entities, which was provided to the Chief Counsel for Advocacy of the Small Business Administration. 
D. Unfunded Mandates Reform Act 
(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 
VerDate Sep<11>2014 16:45 Apr 29, 2021 Jkt 253001 PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 E:\FR\FM\30APP1.SGM 30APP1jbell on DSKJLSW7X2PROD with PROPOSALS22928 Federal Register / Vol. 86, No. 82 / Friday, April 30, 2021 / Proposed Rules 
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. 1531–1538 et seq.). 
E. Executive Order 13132: Federalism 
This action will not have federalism 
implications because it is not expected 
to 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 (64 FR 43255, August 10, 1999). 
F. Executive Order 13175: Consultation 
and Coordination With Indian Tribal Governments 
This action will not have Tribal 
implications because it is not expected 
to have substantial direct effects on Indian Tribes, significantly or uniquely affect the communities of Indian Tribal governments, and does not involve or impose any requirements that affect Indian Tribes, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000). 
G. Executive Order 13045: Protection of 
Children From Environmental Health and Safety Risks 
This action is not subject to Executive 
Order 13045 (62 FR 19885, April 23, 1997), because this is not an economically significant regulatory action as defined by Executive Order 12866, and this action does not address environmental health or safety risks disproportionately affecting children. 
H. Executive Order 13211: Actions 
Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use 
This proposed rule is not subject to 
Executive Order 13211 (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 section 12(d), 15 U.S.C. 272 note, does not apply to this action. J. Executive Order 12898: Federal 
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations 
This action does not entail special 
considerations of environmental justice related issues as delineated by Executive Order 12898 (59 FR 7629, February 16, 1994).

Government Affairs Bureau at (202) 418–0530 (VOICE), (202) 418–0432 (TTY). 
In support of its channel substitution 
request, the Petitioner states that the Commission has recognized that VHF channels have certain propagation characteristics which may cause reception issues for some viewers, and also that the reception of VHF signals requires larger antennas, that are generally not well suited to the mobile applications expected under flexible use, relative to UHF channels. According to the Petitioner, KECI–TV has received numerous complaints from viewers unable to receive an over-the-air signal, despite being able to receive signals from other stations. In addition, the Petitioner states that while the proposed channel 20 noise limited contour does not completely encompass the relevant channel 13 noise limited contour, there would be a loss of service to only 65 people. In addition, the Petitioner states that KECI–TV’s proposed channel 20 facility is predicted to serve a total of 252,689 persons, a net gain of 38,879 potential viewers over the existing KECI–TV channel 13 facility. The Bureau used the technical parameters of KECI–TV’s original post-transition digital channel 13 facility (File No. BPCDT– 20080327AFR) in determining any predicted loss which may occur from the proposed channel substitution. 
Pursuant to §§ 1.415 and 1.419 of the 
Commission’s rules, 47 CFR 1.415, 1.419, interested parties may file comments and reply comments on or before the dates indicated in the
