Amendment No. 11 revises the certificate of compliance to add a new concrete cask, transfer cask, fuel baskets and revised contents. Amendment No. 11 also adds a definition for the concrete cask lid, clarifies the definition for the concrete cask to exclude the lid, 
clarifies the definition of storage cask, and provides alternate fabrication criteria and techniques for the concrete cask lid. Amendment No. 12 and revisions to Amendment Nos. 0 through 9 add definitions for the storage cask and concrete cask lid, revise the definition of the concrete cask, and provide alternate fabrication criteria and techniques for the concrete cask lid to the certificate of compliance. 
In the direct final rule, the NRC stated 
that if no significant adverse comments were received, the direct final rule would become effective on October 16, 2023. The NRC did not receive any comments on the direct final rule. Therefore, this direct final rule will become effective as scheduled.

AGENCY : Office of Energy Efficiency and

ACTION : Final rule; technical 
amendment. 
SUMMARY : The Department of Energy 
(DOE) is amending its standards for 
commercial packaged boilers (CPB) in compliance with a United States Court of Appeals for the District Court of Columbia Circuit court decision vacating the January 10, 2020 rule that amended standards for CPB. 
DATES : This action is effective on 
September 19, 2023. However, the opinion had legal effect on August 28, 2023.

SUPPLEMENTARY INFORMATION : The 
Energy Policy and Conservation Act of 1975 (EPCA), as amended, requires DOE to, among other things, periodically consider whether amended energy conservation standards for commercial packaged boilers are warranted. On January 10, 2020, DOE published a final rule, 85 FR 1592 (January 10, 2020; ‘‘January 2020 Final Rule’’), amending energy conservation standards for commercial packaged boilers (‘‘CPB’’). A commercial packaged boiler is a packaged boiler that meets all of the following requirements: (1) has rated input of 300,000 Btu/h or greater; (2) is to any significant extent, distributed in commerce for space conditioning and/or service water heating in buildings but does not meet the definition of ‘‘hot water supply boiler’’; (3) does not meet the definition of ‘‘field-constructed’’; and (4) is designed to operate a steam pressure at or below 15 psig; operate at or below a water pressure of 160 psig and water temperature of 250 °F, or 
operate at a steam pressure at or below 15 psig and at or below a water pressure of 160 psig and water temperature of 250°F. 10 CFR 431.82. 
The American Public Gas Association 
(‘‘APGA’’), Air-Conditioning, Heating and Refrigeration Institute (‘‘AHRI’’), and Spire Inc. filed petitions for review of DOE’s January 2020 Final Rule in the United States Courts of Appeals for the 
D.C. Circuit, Fourth Circuit, and Eight Circuit, respectively. American Public Gas Association v. DOE, 22 F.4th 1018 
(D.C. Cir. 2022). The Petition was consolidated in the D.C. Circuit. In a January 18, 2022, opinion, the D.C. Circuit determined that DOE failed to 
provide meaningful responses to comments with respect to three distinct issues related to modeling used during the rulemaking proceeding: (1) the random assignment of boiler efficiencies to buildings; (2) forecasted fuel prices; and (3) estimated burner operating hours. As such, the court concluded DOE failed to adequately explain why the January 2020 Final Rule satisfies the applicable clear and convincing 
evidence standard and remanded, but did not vacate, the January 2020 Final Rule to DOE to cure the failures to explain. 
On remand, DOE published a 
supplemental response to comments providing additional explanation regarding these three issues. 87 FR 23421 (April 20, 2022). APGA, AHRI, and Spire Inc. filed separate petitions for review of the supplemental response to comments, which were consolidated in the D.C. Circuit. The D.C. Circuit issued an opinion on July 7, 2023, granting the petition for review and vacating the energy conservation standards for CPBs established in the January 2020 Final Rule, and remanding the proceedings to DOE. (See 10 CFR 431.87) 
This final rule is not subject to the 
requirement to provide prior notice and an opportunity for public comment pursuant to 5 U.S.C. 553(b)(B). DOE finds good cause to waive the requirement to provide prior notice and an opportunity for public comment as such procedure is unnecessary. DOE must comply with the order of a Federal court, and has no discretion to do otherwise. In implementation of that order, DOE is vacating the current energy conservation standards for commercial packaged boilers. Comments suggesting any other course would serve no useful purpose. 
Approval of the Office of the Secretary 
The Secretary of Energy has approved 
publication of this final rule; technical 
amendment. Signing Authority 
This document of the Department of 
Energy was signed on September 8, 2023, by Francisco Alejandro Moreno, Acting Assistant Secretary for Energy Efficiency and Renewable Energy, pursuant to delegated authority from the Secretary of Energy. That document with the original signature and date is maintained by DOE. For administrative purposes only, and in compliance with requirements of the Office of the Federal Register, the undersigned DOE Federal Register Liaison Officer has been authorized to sign and submit the document in electronic format for publication, as an official document of the Department of Energy. This administrative process in no way alters the legal effect of this document upon publication in the Federal Register. 
Signed in Washington, DC, on September 
11, 2023. 
Treena V. Garrett, Federal Register Liaison Officer, U.S. 
Department of Energy.

SUPPLEMENTARY INFORMATION : On August 
30, 2021 (88 FR 44031), the DNFSB published a direct final rule to implement the Debt Collection Act (DCA), as amended, 31 U.S.C. 3701, et seq. The DCA governs the federal 
government’s debt collection activities. In accordance with this law, the Treasury Department and the Department of Justice jointly promulgated Federal Claims Collection Standards (FCCS), 31 CFR parts 900 through 904. Agencies may adopt the FCCS without change or may prescribe agency regulations for collecting debts by administrative offset that are consistent with the FCCS. 31 U.S.C. 3716. These regulations are required before an agency may collect a debt by administrative offset. 
In the direct final rule, the DNFSB 
stated that, if no significant adverse comments were received, the direct final rule would become effective on October 11, 2023. The DNFSB received one comment. The DNFSB evaluated the comment against the criteria described in the direct final rule and determined that the comment was not significant and adverse. Specifically, the commentator stated that the rule would be ‘‘great’’ due to ‘‘the added measure of structure and accountability that will result from this rule.’’ The comment was positive and supportive. The direct final rule will become effective as scheduled.

SUPPLEMENTARY INFORMATION : 
I. Background 
These regulations implement the debt 
collection procedures provided under section 5 of the Debt Collection Act (DCA), as amended, codified at 5 U.S.C. 5514. The DCA authorizes the federal government to collect debts by offset from the salaries of federal employees without the employee’s consent, provided that the employee is properly notified and given the opportunity to exercise certain administrative rights. 
The DCA, codified at 5 U.S.C. 5514, 
made changes in the way executive agencies collect debts owed to the federal government. The purpose of the DCA is to improve the ability of the government to collect money owed to it. The DCA requires each agency to establish a salary offset program for the collection of debts owed by federal employees to the federal government. Before an agency may collect a debt by salary offset, an employee-debtor must be provided with notice of the debt and the opportunity to (1) inspect and copy government records relating to the debt, (2) enter into a written repayment agreement, and (3) request an impartial hearing on the agency’s determination of the existence or the amount of the debt. The employee must notify the agency of his or her intent to exercise these rights within the time prescribed in the agency’s regulations.
