28520 Federal Register / Vol. 86, No. 101 / Thursday, May 27, 2021 / Proposed Rules 
current proposal to remove the language 
from this regulation regarding test methods for gaseous fluorides would correct this inconsistency by removing this remaining language from South Carolina Regulation 61–62.5, Standard No. 2—Ambient Air Quality Standards. 
III. Analysis of the State’s Submittal 
The analysis previously provided by 
EPA in its June 29, 2017 action 
approving removal of gaseous fluorides (as hydrogen fluoride) from South Carolina Regulation 61–62.5, Standard No. 2—Ambient Air Quality Standards, remains applicable today. Gaseous fluorides (as hydrogen fluoride) are not criteria pollutants. They are hazardous air pollutants, which SC DHEC regulates under South Carolina Regulation 61– 62.5, Standard No. 8—Toxic Air Pollutants, a regulation that is outside of 
South Carolina’s SIP. Approving the removal of this language from the South 
Carolina SIP is appropriate because there are no primary or secondary national ambient air quality standards related to this pollutant and because the testing standards for gaseous fluorides do not function in the SIP because EPA previously removed the standards for these pollutants from the SIP. The remaining changes to South Carolina Regulation 61–62.5, Standard No. 2— Ambient Air Quality Standards are non- substantive formatting changes. For these reasons, this SIP revision would not interfere with any applicable requirement concerning attainment and reasonable further progress or any other CAA requirement pursuant to CAA section 110(l). 
IV. Incorporation by Reference 
In this document, EPA is proposing to 
include in a final EPA rule regulatory 
text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference South Carolina Regulation 61–62.5, Standard No. 2—Ambient Air Quality Standards, state effective on April 24, 
2020. EPA has made and will continue to make these materials generally available through www.regulations.gov and at the EPA Region 4 office (please contact the person identified in the 
FOR 
FURTHER INFORMATION CONTACT section of 
this preamble for more information). 
V. Proposed Action 
EPA is proposing to approve SC 
DEHC’s April 24, 2020 SIP submittal 
proposing revisions to South Carolina Regulation 61–62.5, Standard No. 2— Ambient Air Quality Standards and incorporate those revisions into the SIP. EPA has determined that these revisions meet the applicable requirements of sections 110 of the CAA and applicable regulatory requirements at 40 CFR part 51. 
VI. Statutory and Executive Order 
Reviews 
Under the CAA, the Administrator is 
required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. See 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. This proposed action merely proposes to approve state law as meeting Federal requirements and does not propose to impose additional requirements beyond those imposed by state law. For that reason, this proposed action: 
•Is not a significant regulatory action 
subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); 
•Does not impose an information 
collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); 
•Is certified as not having a 
significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); 
•Does not contain any unfunded 
mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); 
•Does not have Federalism 
implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); 
•Is not an economically significant 
regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); 
•Is not a significant regulatory action 
subject to Executive Order 13211 (66 FR 28355, May 22, 2001); 
•Is not subject to requirements of 
Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and 
•Does not provide EPA with the 
discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). 
Because this proposed rule merely 
approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law, this proposed rule for the State of South Carolina does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). Therefore, this action will not impose substantial direct costs on Tribal governments or preempt Tribal law. The Catawba Indian Nation (CIN) Reservation is located within the boundary of York County, South Carolina. Pursuant to the Catawba Indian Claims Settlement Act, S.C. Code Ann. 27–16–120 (Settlement Act), ‘‘all state and local environmental laws and regulations apply to the [Catawba Indian Nation] and Reservation and are fully enforceable by all relevant state and local agencies and authorities.’’ The CIN also retains authority to impose regulations applying higher environmental standards to the Reservation than those imposed by state law or local governing bodies, in accordance with the Settlement Act.

I. Background 
1. On January 15, 2021, the 
Commission released a NPRM seeking 
input on the feasibility of allowing 
flexible-use services in the 12.2–12.7 GHz band (12 GHz band) while protecting incumbents from harmful interference.
2In response to an 
unopposed motion filed by CCIA, et al. for an extension of time to file comments and replies to the NPRM,
3the Wireless Telecommunication Bureau 
(Bureau) released an Order on March 29, 2021, allowing an additional 30 days to file comments and replies (Extension Order).
4The Bureau agreed with the 
parties that a 30-day extension was ‘‘warranted to provide commenters with additional time to prepare comments and reply comments that fully respond to the complex economic, engineering, and policy issues raised in the NPRM.’’
5 
The Bureau, however, declined the 12 GHz Alliance’s request to suspend the deadlines until RS Access, LLC (RS Access) provided certain technical analyses, noting that such action might be rendered moot by the grant of the Extension Request.
6 
2. On April 26, 2021, the 12 GHz 
Alliance filed a request for a further extension of the comment and reply comment deadlines (Further Extension Request)
7stating that, as previously 
explained, ‘‘the submission of the RS Sharing Studies is a gating criteria with respect to the ability of satellite stakeholders to prepare meaningful comments and that absent [that submission] a further extension of the comment cycle may be required.’’
8The 
12 GHz Alliance notes that in the Extension Order, the Bureau ‘‘hoped that this issue would ‘be rendered moot’ by the extension of the comment cycle.’’
9The Further Extension Request has received both opposition10and 
support.11 
3. RS Access opposes the Further 
Extension Request, which it views as 
claiming that RS Access is somehow obliged to file comments before the deadline for initial comments. RS Access states that it ‘‘is preparing comments in anticipation of the May 7, 2021 deadline for initial comments, which will include a coexistence study demonstrating the feasibility of sharing between co-primary systems in the 12.2–12.7 GHz band.’’
12The 5G for 
12GHz Coalition also opposes the Further Extension Request, arguing that it is inappropriate because the Bureau dismissed this same request in the Extension Order.
13 
4. The Commission denies the Further 
Extension Request. As set forth in § 1.46 of the Commission’s rules,
14the 
Commission does not routinely grant extensions of time for filing comments

15Extension Order at para. 3. in rulemaking proceedings. In this 
proceeding, the Bureau has already granted a 30-day extension of comment and reply deadlines to allow parties 
additional time to develop submissions that address complex issues raised in the Notice.
15Because a further 
extension of time would only delay receipt of these comments and parties will have time to reply to these submissions, the Commission is not persuaded that such an extension is warranted. To the extent that members of the 12 GHz Alliance have input on whether filings in the comment stage demonstrate the feasibility of sharing in this band, they may submit such input at the reply stage and in subsequent ex parte presentations. The Commission 
therefore denies the Further Extension Request. The deadlines for filing comments and reply comments in this proceeding continue to be May 7, 2021, and June 7, 2021, respectively. 
II. Ordering Clause 
5. Accordingly, it is ordered that, 
pursuant to section 4(i) of the 
Communications Act of 1934, as amended, 47 U.S.C. 154(i), 0.131, 0.331, and § 1.46 of the Commission’s rules, 47 CFR 0.131, 0.331, and § 1.46, the Further Extension Request filed by WorldVu Satellites Limited (ONEWEB), Kepler Communications, SpaceX Holdings, LLC, Intelsat License LLC, and SES S.A., on April 26, 2021, is denied.

Synopsis 
1. In 2017, the Commission 
established service rules for fixed and 
mobile operation in the 24.25–24.45 GHz and 24.75–25.25 GHz bands (collectively, 24 GHz band) under the Upper Microwave Flexible Use Service (UMFUS). The Commission applied the UMFUS rules, including the technical rules, to the 24 GHz band. The UMFUS rules specify that emissions outside of a licensee’s assigned frequency block must be limited to ¥13 dBm/MHz. With respect to the passive systems operating in the 23.6–24 GHz band, the Commission noted that ongoing international studies include analyses to determine International Mobile Telecommunications (IMT) out-of-band emission limits necessary to protect passive sensors onboard weather satellites in that band, and it acknowledged that the Commission’s UMFUS rules might be revisited once these international studies have been completed. 
2. WRC–19 allocated 24.25–25.25 GHz 
to mobile (except aeronautical) on a primary basis in Regions 1 and 2, globally identified the 24.25–27.5 GHz band for IMT, and established limits of unwanted emissions that apply to IMT in the 24.25–27.5 GHz band to protect Earth Exploration-Satellite Service (EESS) passive systems in the 23.6–24.0 GHz band from harmful interference. To protect EESS passive systems, WRC–19 modified a footnote to the International Table of Allocations to specify that Resolution 750 (Rev. WRC–19) applies to the 24.25–27.5 GHz band. Resolution 750 specifies unwanted emission limits as the amount of power that may be radiated into any 200 megahertz of the 23.6–24.0 GHz passive band by IMT base stations and IMT mobile stations operating in the 24.25–27.5 GHz band. Resolution 750 specifies unwanted emission limits in terms of Total Radiated Power (TRP) that currently apply to IMT stations and stricter emission limits that are effective for IMT stations brought into use after September 1, 2027. These unwanted emission limits are shown in Table 1.

3. The WRC–19 Final Acts updated 
the ITU Radio Regulations, including Resolution 750. The National Telecommunications and Information Administration (NTIA), FCC, and the Department of State share responsibility for implementing the WRC Final Acts in the United States. The Commission has authority to implement the changes to the Radio Regulations through its rulemaking proceedings. Given the importance of limiting unwanted emissions into the passive 23.6–24.0 GHz band, OET and WTB seek to develop a record on implementing the changes to the emission limit in Resolution 750 applicable to active services in the 24 GHz band. 
4. OET and WTB seek comment 
broadly on implementing certain of the WRC–19 outcomes with respect to the 24.25–27.5 GHz band. Noting that the United States is a signatory to the treaty text of the Radio Regulations, OET and WTB seek comment on modifying the Commission’s rules in response to the unwanted emission limits and international allocation table footnotes adopted for the 24.25–27.5 GHz band at the WRC–19. These rule changes could include, for example, adding footnotes to the United States Table of Frequency
