SUPPLEMENTARY INFORMATION: Throughout this document wherever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean the EPA. I. Background On August 29, 2016, the EPA finalized revised Standards of Performance (NSPS) for new MSW landfills and EG for existing MSW landfills in 40 CFR part 60, subparts XXX and Cf, respectively. See 81 FR 59331 and 59313. These rulemaking actions were taken in accordance with section 111 of the CAA. Section 111(d) of the Act requires the EPA establish procedures for a state to submit a plan to the Agency that establishes standards of performance for any ’existing’ source for any air pollutant, (1) for which air quality criteria have not been issued or which is not included on a list published under CAA section 108, or emitted from a source category which is regulated under CAA section 112, but (2) to which a new source performance standard under section 111(b) would apply if such existing source were a ‘new’ source. The EPA established general provisions for submittal of state plans for 111(d) sources in 40 CFR part 60, subpart B. State plan submittals for 111(d) sources must be consistent with the requirements of these general provisions and also establish performance standards and other requirements at least as stringent as those established by the relevant EG as published in 40 CFR part 60. Upon state plan submittal, the EPA reviews a state’s plan for consistency with the requirements of the general provisions and specific EG. If the state plan is complete and approvable with reference to these requirements, the Agency notifies the public, promulgates the plan in 40 CFR part 62 and delegates implementation and enforcement of the standards and requirements of the EG to the state under the terms of the state plan as published in the CFR. Today’s E:\FR\FM\01JYP1.SGM 01JYP1 Federal Register / Vol. 86, No. 124 / Thursday, July 1, 2021 / Proposed Rules action concerns the completeness and approvability of Colorado’s 111(d) state plan for existing MSW landfills. khammond on DSKJM1Z7X2PROD with PROPOSALS II. Summary and Analysis of the Plan Submittal The Executive Director of CDPHE submitted a final 111(d) state plan for existing MSW landfills on March 23, 2021 in response to the August 29, 2016 finalization of the revised EG published at 40 CFR part 60, subpart Cf. The EPA has reviewed the Colorado plan submittal in the context of the plan completeness and approvability requirements found in 40 CFR part 60, subparts B and Cf, as well as the general provisions for plan approval found in 40 CFR part 62, subpart A. The EPA is proposing with this action to approve Colorado’s submittal. If EPA finalizes the proposed action in a future final rulemaking, EPA will promulgate the plan under 40 CFR part 62, subpart G. The Colorado state plan submittal package includes all materials necessary to be deemed administratively and technically complete according to the criteria of 40 CFR part 60, subpart B. Colorado has chosen to author a state plan document (the ‘‘111(d) Plan for Existing Municipal Solid Waste Landfills in Colorado’’) and provide all implementation and enforcement authority for all state plan requirements through revisions to the Code of Colorado Regulations (CCR). Specifically, the State has appropriately incorporated all general EG performance standards and other source requirements in 5 CCR 1001–8 and has given more specific instruction to designated facilities within the state plan document. Both the adopted state plan document and the relevant CCR section, as well as all other relevant plan submittal materials may be found in the docket for today’s action. Necessary State legal and enforcement authorities required for plan approval are located elsewhere in Colorado statute, rules and regulations and have been reviewed and approved of by the EPA in the course of prior section 111(d) or 111(d)/129 state plan approvals. See 40 CFR 62.1350–1400. Following the EPA’s review of the submittal materials, the Agency finds the state plan package to be approvable according to all plan requirements. Analysis of the submitted state plan’s completeness and approvability, with reference to the relevant general and source category specific plan requirements of 40 CFR part 60, subparts B and Cf, and a detailed explanation of the rationale supporting this proposed approval is available in VerDate Sep<11>2014 16:17 Jun 30, 2021 Jkt 253001 the Technical Support Document (TSD) in the docket of this proposed rule. III. Proposed Action The EPA is proposing to approve the Colorado section 111(d) state plan for MSW landfills. The state plan was submitted in full compliance with the requirements of 40 CFR part 60, subparts B and Cf. Therefore, the EPA is proposing to amend 40 CFR part 62, subpart G to reflect this approval action. This approval is based on the rationale provided in section II of this preamble and discussed in detail in the TSD associated with this rulemaking action. The Agency’s approval is in accordance with the general provisions of plan approval found in 40 CFR part 60, subpart B and in part 62, subpart A of that Title and is pursuant to the Agency’s role under 42 U.S.C. 7411(d). The EPA’s proposed approval of the Colorado plan is limited to those landfills that meet the criteria established in 40 CFR part 60, subpart Cf and grants the State authority to implement and enforce the performance standards and source requirements of the EG, except in those cases where authorities are specifically reserved for the EPA Administrator or his designee. Authorities retained by the EPA Administrator are those listed in 40 CFR 60.30f(c) IV. Incorporation by Reference In this document, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference of the state plan. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference CDPHE and Colorado Air Quality Control Commission regulations regarding MSW landfills discussed in section II of this preamble. The EPA has made, and will continue to make, these materials available through the docket for this action, EPA–R08–OAR–2021–0004, at https://www.regulations.gov and at the EPA Region 8 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). V. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a 111(d) state plan submittal that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7411(d); 40 CFR 62.02(a). Thus, in reviewing 111(d) plan submittals, the EPA’s role is to approve state choices, provided that they meet the criteria of the CAA and the relevant provisions of 40 CFR part PO 00000 Frm 00047 Fmt 4702 Sfmt 4702 35045 60. Accordingly, this action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this 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). In addition, the Colorado 111(d) state plan for existing MSW landfills is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the proposed rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

Synopsis 1. In this Notice of Proposed Rulemaking (NPRM), the Commission proposes to revise the applicable technical rules for operation of part 74 low-power auxiliary station (LPAS) devices to permit a recently developed type of wireless microphone system, termed herein as a Wireless MultiChannel Audio System (WMAS), to operate in the broadcast television (TV) bands and other part 74 LPAS frequency bands on a licensed basis. This emerging technology would enable more wireless microphones to operate in the spectrum available for wireless microphone operations, and thus advances an important Commission goal of promoting efficient spectrum use. The Commission propose and seek comment on technical rules for WMAS operations under our part 74 LPAS rules for licensed wireless microphone operations as well as the particular frequency bands in which WMAS wireless microphones would be permitted to operate. The Commission also seeks comment on whether to permit WMAS under the part 15 rules that allow unlicensed wireless microphone operations in the TV bands, the 600 MHz guard band, and 600 MHz duplex gap. The Commission also proposes to update our existing part 74 LPAS and part 15 technical rules for wireless microphones, which already rely on certain European Telecommunications Standards Institute (ETSI) standards, to incorporate the latest version of that standard where appropriate. Finally, the Commission proposes to update the wireless microphone rules to reflect the end of the post-Incentive auction transition period. Its aim in this proceeding is to enhance the spectral efficiency of wireless microphone use. The Commission does not intend to alter the existing spectrum rights—or PO 00000 Frm 00048 Fmt 4702 Sfmt 4702 expectations regarding access and availability of spectrum—vis-a`-vis all the various authorized users, whether broadcast licensees, white space device users, the wireless microphone users themselves, or others, that share frequency bands with wireless microphones. 2. Background. Many types of users employ wireless microphones in a variety of settings including theaters and music venues, film studios, conventions, corporate events, houses of worship, and internet webcasts. Wireless microphone operations range from professional uses, with the need for numerous high-performance microphones, to an individual consumer’s use of a handheld microphone at a conference or in a karaoke bar. These devices are authorized for operations both on a licensed and unlicensed basis, depending on the frequency band. Most licensed wireless microphones operate under the part 74 rules for low power auxiliary stations (LPAS) on a secondary basis. Under those rules, they can operate on unused spectrum in the TV bands (both VHF and UHF), a 4megahertz portion of the 600 MHz duplex gap, certain frequencies in the 900 MHz band, the 1435–1525 MHz band (shared with federal Aeronautical Mobile Telemetry (AMT) service), and portions of the 7 GHz band. Entities eligible for part 74 licenses include broadcast station licensees and networks, certain cable television operators, motion picture/TV producers, and professional sound companies and venue operators that routinely use 50 or more wireless microphones. Unlicensed wireless microphones also operate in certain bands under the part 15 rules— including the VHF and UHF–TV bands where they generally share the same basic technology used by licensed LPAS wireless microphones (although unlicensed operations are limited to lower, more restrictive power levels than licensed operations). 3. Historically and currently, most wireless microphones—both licensed and unlicensed—operate on unused spectrum in the TV bands where they share use of unused TV band spectrum with unlicensed white space devices. The spectrum available for these devices has decreased in recent years as a result of the Commission’s actions that repurposed some portions of the TV bands for wireless services and repacked the TV bands. In 2015 and 2017, the Commission took several actions focused either on promoting more efficient use of the spectrum by both licensed and unlicensed wireless microphone operations in the repacked E:\FR\FM\01JYP1.SGM 01JYP1

SUPPLEMENTARY INFORMATION: Throughout this document wherever ``we,'' 
``us,'' or ``our'' is used, we mean the EPA.

I. Background

    On August 29, 2016, the EPA finalized revised Standards of 
Performance (NSPS) for new MSW landfills and EG for existing MSW 
landfills in 40 CFR part 60, subparts XXX and Cf, respectively. See 81 
FR 59331 and 59313. These rulemaking actions were taken in accordance 
with section 111 of the CAA. Section 111(d) of the Act requires the EPA 
establish procedures for a state to submit a plan to the Agency that 
establishes standards of performance for any 'existing' source for any 
air pollutant, (1) for which air quality criteria have not been issued 
or which is not included on a list published under CAA section 108, or 
emitted from a source category which is regulated under CAA section 
112, but (2) to which a new source performance standard under section 
111(b) would apply if such existing source were a `new' source. The EPA 
established general provisions for submittal of state plans for 111(d) 
sources in 40 CFR part 60, subpart B. State plan submittals for 111(d) 
sources must be consistent with the requirements of these general 
provisions and also establish performance standards and other 
requirements at least as stringent as those established by the relevant 
EG as published in 40 CFR part 60. Upon state plan submittal, the EPA 
reviews a state's plan for consistency with the requirements of the 
general provisions and specific EG. If the state plan is complete and 
approvable with reference to these requirements, the Agency notifies 
the public, promulgates the plan in 40 CFR part 62 and delegates 
implementation and enforcement of the standards and requirements of the 
EG to the state under the terms of the state plan as published in the 
CFR. Today's

[[Page 35045]]

action concerns the completeness and approvability of Colorado's 111(d) 
state plan for existing MSW landfills.

II. Summary and Analysis of the Plan Submittal

    The Executive Director of CDPHE submitted a final 111(d) state plan 
for existing MSW landfills on March 23, 2021 in response to the August 
29, 2016 finalization of the revised EG published at 40 CFR part 60, 
subpart Cf. The EPA has reviewed the Colorado plan submittal in the 
context of the plan completeness and approvability requirements found 
in 40 CFR part 60, subparts B and Cf, as well as the general provisions 
for plan approval found in 40 CFR part 62, subpart A. The EPA is 
proposing with this action to approve Colorado's submittal. If EPA 
finalizes the proposed action in a future final rulemaking, EPA will 
promulgate the plan under 40 CFR part 62, subpart G.
    The Colorado state plan submittal package includes all materials 
necessary to be deemed administratively and technically complete 
according to the criteria of 40 CFR part 60, subpart B. Colorado has 
chosen to author a state plan document (the ``111(d) Plan for Existing 
Municipal Solid Waste Landfills in Colorado'') and provide all 
implementation and enforcement authority for all state plan 
requirements through revisions to the Code of Colorado Regulations 
(CCR). Specifically, the State has appropriately incorporated all 
general EG performance standards and other source requirements in 5 CCR 
1001-8 and has given more specific instruction to designated facilities 
within the state plan document. Both the adopted state plan document 
and the relevant CCR section, as well as all other relevant plan 
submittal materials may be found in the docket for today's action. 
Necessary State legal and enforcement authorities required for plan 
approval are located elsewhere in Colorado statute, rules and 
regulations and have been reviewed and approved of by the EPA in the 
course of prior section 111(d) or 111(d)/129 state plan approvals. See 
40 CFR 62.1350-1400. Following the EPA's review of the submittal 
materials, the Agency finds the state plan package to be approvable 
according to all plan requirements.
    Analysis of the submitted state plan's completeness and 
approvability, with reference to the relevant general and source 
category specific plan requirements of 40 CFR part 60, subparts B and 
Cf, and a detailed explanation of the rationale supporting this 
proposed approval is available in the Technical Support Document (TSD) 
in the docket of this proposed rule.

III. Proposed Action

    The EPA is proposing to approve the Colorado section 111(d) state 
plan for MSW landfills. The state plan was submitted in full compliance 
with the requirements of 40 CFR part 60, subparts B and Cf. Therefore, 
the EPA is proposing to amend 40 CFR part 62, subpart G to reflect this 
approval action. This approval is based on the rationale provided in 
section II of this preamble and discussed in detail in the TSD 
associated with this rulemaking action. The Agency's approval is in 
accordance with the general provisions of plan approval found in 40 CFR 
part 60, subpart B and in part 62, subpart A of that Title and is 
pursuant to the Agency's role under 42 U.S.C. 7411(d). The EPA's 
proposed approval of the Colorado plan is limited to those landfills 
that meet the criteria established in 40 CFR part 60, subpart Cf and 
grants the State authority to implement and enforce the performance 
standards and source requirements of the EG, except in those cases 
where authorities are specifically reserved for the EPA Administrator 
or his designee. Authorities retained by the EPA Administrator are 
those listed in 40 CFR 60.30f(c)

IV. Incorporation by Reference

    In this document, the EPA is proposing to include in a final EPA 
rule regulatory text that includes incorporation by reference of the 
state plan. In accordance with requirements of 1 CFR 51.5, the EPA is 
proposing to incorporate by reference CDPHE and Colorado Air Quality 
Control Commission regulations regarding MSW landfills discussed in

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a 111(d) 
state plan submittal that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7411(d); 40 CFR 62.02(a). 
Thus, in reviewing 111(d) plan submittals, the EPA's role is to approve 
state choices, provided that they meet the criteria of the CAA and the 
relevant provisions of 40 CFR part 60. Accordingly, this action merely 
proposes to approve state law as meeting Federal requirements and does 
not impose additional requirements beyond those imposed by state law. 
For that reason, this 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).
    In addition, the Colorado 111(d) state plan for existing MSW 
landfills is not approved to apply on any Indian reservation land or in 
any other area where EPA or an Indian tribe has demonstrated that a 
tribe has jurisdiction. In those areas of Indian country, the proposed 
rule does not have tribal implications and will not impose substantial 
direct costs on tribal governments or preempt tribal law as specified 
by Executive Order 13175 (65 FR 67249, November 9, 2000).
