Energy Conservation Program: Energy 
Conservation Standards for Manufactured Housing; Enforcement 
AGENCY : Office of Energy Efficiency and 
Renewable Energy, Department of Energy. 
ACTION : Notice of proposed rulemaking. 
SUMMARY : The U.S. Department of 
Energy (DOE) is proposing to establish enforcement procedures for its energy conservation standards for 
manufactured housing. DOE recently amended the compliance date for these standards in a final rule to delay compliance. DOE delayed the compliance date to allow DOE more time for this rulemaking to establish enforcement procedures that provide clarity for manufacturers and other stakeholders regarding DOE’s expectations of manufacturers and DOE’s plans for enforcing the standards. 
DATES : DOE will accept comments, data, 
and information regarding the notice of proposed rulemaking received no later than February 26, 2024. See section V, ‘‘Public Participation,’’ for details. 
ADDRESSES : The docket for this 
proposed rulemaking, which includes Federal Register notices, comments, and other supporting documents/ materials, is available for review at www.regulations.gov. All documents in 
the docket are listed in the www.regulations.gov index. However, 
not all documents listed in the index may be publicly available, such as information that is exempt from public disclosure.

I. Background 
The Energy Independence and 
Security Act of 2007 (‘‘EISA,’’ Pub. L. 
110–140) directs the U.S. Department of Energy (‘‘DOE’’ or, in context, ‘‘the Department’’) to establish energy conservation standards for manufactured housing.
1(42 U.S.C. 
17071) Manufactured homes are constructed according to standards administered by the U.S. Department of Housing and Urban Development (‘‘HUD Code’’). 24 CFR part 3280. See also generally 42 U.S.C. 5401–5426. Structures, such as site-built and modular homes, that are constructed to state, local, or regional building codes are excluded from the coverage of the HUD Code.
2 
EISA directs DOE to base its standards 
on the most recent version of the International Energy Conservation Code (‘‘IECC’’) and any supplements to that code, except in cases where DOE finds that the IECC is not cost-effective or where a more stringent standard would be more cost-effective, based on the impact of the IECC on the purchase price of manufactured housing and on total life-cycle construction and operating costs. (See 42 U.S.C. 
17071(b)(1)) 
On June 17, 2016, DOE published in 
the Federal Register a notice of 
proposed rulemaking (‘‘NOPR’’) to propose energy conservation standards for manufactured housing, including proposals recommended by the negotiated rulemaking working group for manufactured housing. 81 FR 39756 (‘‘June 2016 NOPR’’). DOE received nearly 50 comments on the proposed rule during the comment period. In addition, DOE also received over 700 substantively similar form letters from individuals. 
On August 3, 2018, DOE published a 
Notice of Data Availability (‘‘NODA’’), stating it was examining possible alternatives to the requirements proposed in the June 2016 NOPR and seeking further input from the public, including on first-time costs related to the purchase of manufactured homes. 83 FR 38073 (‘‘August 2018 NODA’’). Prior to the NODA, in December of 2017, the Sierra Club filed a lawsuit against DOE in the U.S. District Court for the District of Columbia, alleging that DOE had failed to meet its statutory deadline for establishing energy conservation standards for manufactured housing. Sierra Club v. Granholm, No. 1:17–cv– 
02700–EGS (D.D.C. filed Dec. 18, 2017). In November 2019, the court entered a consent decree in which DOE agreed to complete the rulemaking by stipulated dates. 
After evaluating the comments 
received in response to the June 2016 NOPR and the August 2018 NODA, DOE published a supplemental NOPR (‘‘SNOPR’’) on August 26, 2021, in which DOE proposed energy conservation standards for manufactured homes based on the 2021 IECC. 86 FR 47744 (‘‘August 2021 SNOPR’’). DOE’s primary proposal in the August 2021 SNOPR was a ‘‘tiered’’ approach based on the 2021 IECC. The ‘‘tiered’’ approach identifies a subset of less stringent energy conservation standards for certain manufactured homes (based on retail list price) in light of the cost-effectiveness considerations required by EISA. DOE’s alternate proposal was an ‘‘untiered’’ approach, wherein energy conservation standards for all manufactured homes would be based on certain thermal envelope components and specifications of the 2021 IECC. Both proposals replaced the

June 2016 NOPR proposal. Id. DOE 
sought comment on these proposals, as 
well as alternate thresholds, including a size-based threshold (e.g., square 
footage, number of sections) and a region-based threshold, and alternative exterior wall insulation requirements (R–21) for certain HUD zones. Id. 
On October 26, 2021, DOE published 
a NODA regarding updated inputs and results of the analyses presented in the August 2021 SNOPR (both ‘‘tiered’’ and ‘‘untiered’’ approaches), including a sensitivity analysis regarding an alternative sized-based tier threshold and an alternate exterior wall insulation requirement (R–21) for certain HUD zones. 86 FR 59042 (‘‘October 2021 NODA’’). In addition, DOE reopened the public comment period on the August 2021 SNOPR through November 26, 2021. DOE sought comments on the updated inputs and corresponding analyses, encouraged stakeholders to provide additional data to inform the analyses, and stated it might further revise the rulemaking analysis based on new or updated information. Id. 
On May 31, 2022, DOE published a 
final rule codifying the proposed energy conservation standards for manufactured housing in a new part of the Code of Federal Regulations (‘‘CFR’’) under 10 CFR part 460, subparts A, B, and C (‘‘May 2022 Final Rule’’). 87 FR 32728. Subpart A of 10 CFR part 460 presents generally the scope of the rule and provides definitions of key terms. Subpart B establishes new requirements for manufactured homes that relate to climate zones, the building thermal envelope, air sealing, and installation of insulation, based on certain provisions of the 2021 IECC. Subpart C establishes new requirements based on the 2021 IECC related to duct sealing; heating, ventilation, and air conditioning (‘‘HVAC’’); service hot water systems; mechanical ventilation fan efficacy; and heating and cooling equipment sizing. 
Under the energy conservation 
standards, the stringency of the requirements under subpart B are based on a tiered approach depending on the number of sections of the manufactured home. Accordingly, two sets of standards are established in subpart B (i.e., Tier 1 and Tier 2). Both Tier 1 and 
Tier 2 incorporate building thermal envelope measures based on certain 
thermal envelope components subject to the 2021 IECC that DOE determined applicable and appropriate for manufactured homes. Tier 1 applies these building thermal envelope provisions to single-section manufactured homes, but only includes components at stringencies that would increase the incremental purchase price by less than $750 in order to address affordability concerns that were raised by HUD and other stakeholders during the consultation and rulemaking process. Tier 2 applies these same building thermal envelope provisions to multi-section manufactured homes but at higher stringencies specified for site- built homes in the 2021 IECC, with an alternate exterior wall insulation requirement (R–21) for climate zones 2 and 3 based on consideration of the design and factory construction techniques of manufactured homes, as presented in the August 2021 SNOPR and October 2021 NODA. Manufacturers can comply with the building thermal envelope requirements through a prescriptive pathway (e.g., using 
materials with specified ratings) or a performance pathway based on overall thermal transmittance (Uo) performance. See 10 CFR 460.102(c). 
Further, the energy conservation standards for both tiers also include duct and air sealing, insulation installation, HVAC and service hot water system specifications, mechanical ventilation fan efficacy, and heating and cooling equipment sizing provisions, based on the 2021 IECC. DOE concluded that this approach is cost-effective based on the expected total life-cycle cost (‘‘LCC’’) savings for the lifetime of the home associated with implementation of the energy conservation standards. See e.g., 87 FR 32742. 
In the May 2022 Final Rule, DOE 
adopted a compliance date such that the standards would apply to manufactured homes that are manufactured on or after one year following the publication date of the final rule in the Federal Register, 
which is May 31, 2023. In doing so, DOE noted its belief that many manufacturers already have experience complying with efficiency requirements similar to what DOE required in the May 2022 Final Rule based on manufacturers’ previous experience with HUD Uo requirements and 
ENERGY STAR Version 2 efficiency requirements for homes produced on or after June 1, 2020. 87 FR 32759. DOE did not specify its approach for enforcement of the standards in the May 2022 Final Rule and noted that manufacturers would be able to comply with the standards as they were issued. In fact, DOE noted that many of the requirements in the standards would require minimal compliance efforts (e.g., documenting the use of materials already subject to separate Federal or industry standards, such as the R-value of insulation or U-factor values for fenestration). 87 FR 32758, 32790. Nevertheless, DOE stated in the May 2022 Final Rule that it may address 
compliance and enforcement issues and procedures in a future agency action (see 87 FR 32757–32758), which is 
discussed further in section II of this document. 
On March 24, 2023, DOE published in 
the Federal Register a NOPR proposing 
to amend the compliance date for the manufactured housing energy conservation standards (88 FR 17745, ‘‘March 2023 NOPR’’). In that NOPR, DOE described the need to amend the compliance date for the manufactured housing standards, noting that it had not yet issued procedures for investigating and enforcing against noncompliance with the standards, and that a delay was necessary to ensure that DOE can receive and incorporate meaningful stakeholder feedback into its enforcement procedures prior to part 460’s compliance date. Accordingly, DOE proposed to require compliance with the Tier 1 standards beginning 60 days after publication of its final enforcement procedures, and compliance with the Tier 2 standards beginning 180 days after publication of its final enforcement procedures. By final rule published on May 30, 2023 (May 2023 Final Rule) DOE amended the compliance date for part 460 consistent with its proposed compliance date in the NOPR for Tier 1 (i.e., 60 days 
after issuance of DOE’s enforcement procedures for part 460). However, for Tier 2, DOE amended the compliance date to July 1, 2025. 88 FR 34411. After consideration of comments on the NOPR, DOE determined that amending the compliance date to July 1, 2025, for Tier 2 homes would (1) provide greater certainty for manufacturers versus an indeterminate date, (2) ensure DOE will have enough time to develop enforcement procedures and engage in the rulemaking process, including providing adequate time for stakeholders to submit robust feedback on DOE’s proposed enforcement procedures, and (3) provide manufacturers with sufficient time to adjust their operations and practices 
consistent with DOE’s enforcement procedures. 88 FR 34412. 
II. Discussion of Proposed Rule 
Pursuant to section 413 of the Energy 
Independence and Security Act 
(‘‘EISA’’), DOE is authorized to initiate enforcement actions to ensure compliance with its energy conservation standards for manufactured housing. In this section, DOE provides a section-by- section analysis of its proposed rule to establish procedures for such enforcement actions. As discussed herein, DOE proposes to amend subpart

3As discussed in the Notice of Noncompliance 
section, for the first five years after the compliance 
date for a type of home (Tier 1 or 2), DOE will consider only units the manufacturer sold, 
imported, or distributed in commerce from the compliance date for that type of home (Tier 1 or 2) to the date the notice of noncompliance determination is issued. Once five years has passed from the compliance date for a type of home, DOE will consider units the manufacturer sold, imported, or distributed in commerce for the five 
years prior to the date the notice of noncompliance is issued. D to its regulations at 10 CFR part 460 
to set forth prohibited acts, civil penalty amounts, investigation and enforcement procedures, recordkeeping requirements, and civil penalty collection procedures. In particular, DOE proposes that it will determine compliance by reviewing certain manufacturer records. DOE is not proposing specific test procedures to demonstrate compliance with DOE’s standards. Nor is DOE proposing to require manufacturers to certify that their manufactured home models comply with DOE’s standards. In addition, DOE proposes to clarify that manufacturers may demonstrate compliance with the 10 CFR 460.205 requirements for sizing of heating and cooling equipment by using either the approach in the Air Conditioning Contractors of America (ACCA) Manual J and ACCA Manual S or the approach codified in HUD’s regulations at 24 CFR 3280.508. 
General Counsel Responsibilities 
Proposed § 460.302 provides that the 
Office of the DOE General Counsel may 
assist in investigations of alleged violations of part 460, prosecute civil enforcement actions under part 460, compromise and assess civil penalties initiated under part 460, represent DOE in any formal proceedings or hearings before an Administrative Law Judge 
(‘‘ALJ’’) in cases involving alleged violations of part 460, and refer cases to the Attorney General for the collection of civil penalties. 
Prohibited Acts and Civil Penalties 
Proposed § 460.304 lists prohibited 
acts that will be subject to civil 
enforcement action under part 460. These prohibited acts include the sale, importation, or distribution into commerce in the United States of a manufactured home that is not in compliance with any energy conservation standard or requirement in part 460. (42 U.S.C. 17071) They also include any failure of a manufacturer to maintain, provide to DOE, or permit DOE access to any information, records, or documents required under part 460. 
DOE also proposes in § 460.304 to 
clarify that certain acts relating to sizing of heating and cooling equipment comply with the energy conservation standard and do not constitute a violation under § 460.304(a)(2). Specifically, in § 460.304(d), DOE proposes to clarify that a manufacturer may use the approach codified in HUD regulations referencing the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Handbook of Fundamentals for determining manufactured home heat 
loss/heat gain. See 24 CFR 3280.508. 
DOE is proposing to clarify that this approach can be used in lieu of using Air Conditioning Contractors of America (ACCA) Manual J and ACCA Manual S for sizing of heating and cooling equipment as specified in the energy conservation standard at 10 CFR 460.205. DOE has tentatively determined that both approaches sufficiently align with the intent of 10 CFR 460.205 supporting appropriate sizing of heating and cooling equipment in manufactured housing and are not expected to impact the stringency of the energy conservation standards in § 460.205. Further, DOE understands that certain details of the final installation location, such as the house orientation, may not always be available when equipment sizing is occurring. Thus, DOE proposes to allow an alternate sizing approach to be used as specified by the ASHRAE Handbook of Fundamentals pursuant to the methodology adopted by HUD. 
Proposed § 460.304 explains the 
potential civil penalties for prohibited acts under part 460. It provides that a manufacturer that commits a prohibited act may be subject to assessment of a civil penalty of up to one percent of the manufacturer’s retail list price of the manufactured home per violation, in keeping with the maximum civil penalty for violations of provisions of DOE’s energy conservation manufactured housing regulations set forth in accordance with section 413(c) of EISA. 
Proposed § 460.304 also describes 
how DOE will calculate civil penalties for prohibited acts. It provides that each day a manufacturer fails to maintain, provide, or permit access to information, records, or documents will be considered a separate violation. It also provides that each failure to comply with a standard or requirement of part 460, per unit sold, imported, or introduced into commerce in the United States, will be considered a separate violation. For example, if a manufactured home model fails to comply with three standards in part 460, the manufacturer has sold, 
imported, or distributed in commerce 100 units of that model,
3and the retail list price of that model is $200,000, then 
the manufacturer will subject to a civil penalty of up to $600,000 ($200,000 retail list price × 1% × 3 violations × 100 
units). 
DOE notes that section 413 of EISA 
does not specifically provide for the assessment of civil penalties for a manufacturer’s failure to maintain or provide to DOE information, records, or documents. However, section 413(a) requires the Secretary, by regulation, to establish standards for energy efficiency in manufactured housing. Section 413(c) provides that any manufacturer of manufactured housing that violates a provision of the regulations issued under section 413(a) is liable to the United States for a civil penalty. DOE is proposing to add these enforcement procedures pursuant to section 413(a) to 
carry out its obligation under EISA to ensure that manufacturers comply with DOE’s energy conservation standards. Accordingly, DOE is proposing to require manufacturers to maintain and provide information, records, and documents related to compliance with DOE’s energy conservation standards, and subjecting manufacturers that fail or refuse to do so to civil penalties, so that DOE can ensure that manufacturers provide DOE with the records necessary to determine whether they are complying with the manufactured housing energy conservation standards. DOE is also evaluating and considering its subpoena authority under EISA. 
In addition, the Secretary has the 
authority under 42 U.S.C. 7254 to prescribe procedural and administrative rules and regulations that the Secretary ‘‘may deem necessary or appropriate to administer and manage the functions now or hereafter vested in’’ the Secretary. Under 42 U.S.C. 7101(b), the term ‘‘function’’ includes reference to any duty, obligation, power, authority, responsibility, right, privilege, and activity, or the plural thereof. The Secretary has determined that the proposed recordkeeping requirements and civil penalties in this rulemaking are necessary to administer and manage the Secretary’s duties and obligations under EISA. 
Investigation Procedures 
Proposed § 460.306 explains how 
DOE will conduct investigations to 
determine whether manufacturers are in compliance with the energy conservation standards and other requirements of part 460. DOE may initiate an investigation on its own or upon receipt of information alleging 
VerDate Sep<11>2014 16:17 Dec 22, 2023 Jkt 262001 PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 E:\FR\FM\26DEP1.SGM 26DEP1khammond on DSKJM1Z7X2PROD with PROPOSALS88847 Federal Register / Vol. 88, No. 246 / Tuesday, December 26, 2023 / Proposed Rules

proposed rule shall be distinct from any other 
notices issued to a manufacturer by other agencies under their respective enforcement authority. potential noncompliance. DOE will not 
require manufacturers to certify to the Department that their designs or manufactured homes comply with part 460. Rather, DOE may request that a manufacturer provide one or more of the records listed in this section so that DOE can determine whether the manufacturer is in compliance with the requirements of part 460. If DOE makes such a request of a manufacturer during an administrative action, investigation, or audit conducted by DOE pursuant to part 460, the manufacturer will be required to provide the requested records to DOE. As discussed previously, if a manufacturer fails or refuses to do so, the manufacturer will be subject to civil penalties. 
Paragraph (a) of the proposed 
§ 460.306 lists four types of records that DOE may request from a manufacturer to determine whether the manufacturer is in compliance with part 460. These are records that manufacturers must already maintain or provide to the Department of Housing and Urban Development (‘‘HUD’’) pursuant to HUD regulations in 24 CFR part 3282.
4Under 
proposed paragraph (c), DOE may request additional available records if DOE determines they are necessary as part of an administrative action, investigation, or audit. During the course of any such action, investigation, or audit, DOE also may obtain additional information and records from publicly available sources. 
DOE proposes to require 
manufacturers to maintain the records listed in paragraph (a) in accordance with HUD requirements. DOE is also 
considering requiring the records it is proposing to require manufacturers to maintain in § 460.306(a) to be retained for a specific period of years. DOE requests comment on whether it should proceed with such a requirement and what period of time may be appropriate. While DOE is not proposing to require manufacturers to maintain any additional records, under paragraph (c), a manufacturer may be required to provide to DOE additional records in its possession if DOE requests such records pursuant to an administrative action, audit, or investigation conducted by DOE against the manufacturer. 
Warning Letters 
Proposed § 460.308 would allow DOE 
to dispose of a matter with a Warning 
Letter if DOE determines that a violation or alleged violation of part 460 does not warrant the assessment of a civil penalty. This proposed section specifies that a Warning Letter issued under this section does not constitute a formal adjudication of the matter and is not subject to the appeal procedures proposed in this proposed rulemaking. 
Notice of Noncompliance Determination 
Proposed § 460.310 provides that if 
DOE determines that a manufactured 
home design or model does not conform to a standard or requirement in part 460, based on DOE’s investigation or admissions by a manufacturer, DOE may issue a notice of noncompliance determination to the manufacturer.
5 
DOE will review records to evaluate whether one or more of the aspects of a manufactured home design or model is noncompliant. If DOE determines that one or more aspects of the design or model is noncompliant, DOE may issue to the manufacturer a notice of noncompliance determination addressing each violation depending on the facts of the specific case. A manufacturer that receives a notice of noncompliance determination from DOE would be required to provide to DOE, within the 30-day time period prescribed by DOE, information pertaining to the acquisition, ordering, storage, shipment, importation, or sale of units of the design or model of manufactured home determined to be noncompliant. 
As noted previously, DOE issued a 
final rule (88 FR 34411) to delay compliance until July 1, 2025, for Tier 2 homes, and until 60 days after issuance of enforcement procedures for Tier 1 homes. Accordingly, for the first five years after the compliance date for a type of home (Tier 1 or 2), DOE will request such information for the time from the compliance date for that type of home (Tier 1 or 2) to the date the notice of noncompliance determination is issued. Once five years has passed from the compliance date for a type of home, DOE will request such information for the five years prior to the date the notice of noncompliance is issued. For example, if DOE issues a notice of noncompliance determination for a Tier 2 manufactured home on August 1, 2027, DOE will request sales and other information for that model from July 1, 2025 (the compliance date for Tier 2 homes), through August 1, 2027. However, if DOE issues a notice of noncompliance determination for a Tier 2 home on August 1, 2031, DOE will request sales and other information for that model for the five years prior to August 1, 2031. DOE will give manufacturers 30 
calendar days to provide the requested information. A manufacturer that fails or refuses to provide such information will be subject to civil penalties under part 460. 
Civil Enforcement Procedures 
Prior to imposing a civil penalty for 
noncompliance with part 460, DOE 
proposes to provide manufacturers with written notice of the proposed penalty and options for responding to the notice. Under proposed § 460.312, a manufacturer that receives a Notice of Proposed Civil Penalty will have 30 days from receipt of the notice to exercise one of the following options: (1) request that DOE issue an Order assessing the civil penalty proposed in the notice, in which case the manufacturer waives the right to request a hearing before an ALJ; (2) request a settlement conference with the DOE attorney who issued the notice, in which case the manufacturer also may submit to DOE additional information and evidence related to the alleged violations, the amount of the proposed civil penalty, and the manufacturer’s ability to pay the proposed civil penalty; or (3) request a hearing before an ALJ. DOE is also considering providing manufacturers the option of seeking judicial review of the notice of civil penalty in a U.S. District Court in lieu of a hearing before an ALJ. DOE requests public comment on whether to include this option. 
DOE proposes in § 460.316 that if: a 
manufacturer does not respond to the notice within 30 days of receipt; the manufacturer selects option (2) but fails to attend the settlement conference; or the manufacturer selects option (2) and DOE and the manufacturer are unable to resolve the matter informally, DOE will issue a Final Notice of Proposed Civil Penalty to the manufacturer. The manufacturer will then have 15 days from receipt of the final notice to exercise one of the following options: (1) request that DOE issue an Order assessing the civil penalty proposed in the final notice, in which case the manufacturer waives the right to request a hearing before an ALJ; or (2) request a hearing before an ALJ. 
If the manufacturer fails to respond to 
the final notice within 15 days of receipt, the manufacturer waives the right to participate in the informal procedures set forth in this subpart and the right to request a formal hearing before an ALJ, and DOE will issue to the manufacturer an Order in which DOE finds that the manufacturer committed the violations alleged, and assesses the

624 CFR 3282.203(g) requires manufacturers to 
maintain a copy of the drawings, specifications, and 
sketches from each approved design received from a DAPIA under 24 CFR 3282.361(b)(4) and a copy of the approved quality assurance manual received from a DAPIA under 24 CFR 3282.361(c)(3). It requires the manufacturer to keep these materials current and readily accessible for use by the Secretary of HUD or other parties acting under the HUD regulations. civil penalty proposed, in the final 
notice. 
Proposed § 460.314 would allow DOE 
to compromise and settle civil penalty cases brought under part 460 at any time prior to a final decision by a Federal court of competent jurisdiction. In compromising or settling a civil penalty case, DOE may consider aggravating and mitigating factors. For more information on DOE’s civil penalty policy, see https://www.energy.gov/gc/articles/civil- penalties-energy-conservation- standards-program-violations-policy- statement. 
If DOE and the manufacturer agree to 
compromise the proposed civil penalty at any time prior to a final decision by a Federal court of competent jurisdiction, DOE will issue to the manufacturer an Order assessing the agreed upon civil penalty. If a manufacturer requested a hearing before an ALJ, and the ALJ’s initial decision recommending a civil penalty is not appealed, DOE will issue an Order assessing the civil penalty recommended by the ALJ. DOE proposes to give manufacturers 30 days after receipt of any Order assessing a civil penalty under part 460 to pay the 
civil penalty. 
DOE believes the procedures in 
proposed §§ 460.312 to 460.316 are necessary to provide for the expeditious resolution of civil penalty cases under part 460, while maintaining the opportunity for manufacturers to engage with DOE to settle cases and providing due process to manufacturers, including the opportunity for hearings before an ALJ and the opportunity to appeal ALJ decisions. 
Administrative Law Judge Hearing and 
Appeal 
Proposed § 460.320 explains that if a 
manufacturer responds to a Notice of Proposed Civil Penalty or Final Notice of Proposed Civil Penalty by electing a formal hearing before an Administrative Law Judge, DOE will conduct such hearings in accordance with DOE’s Procedures for Administrative Adjudication of Civil Penalty Actions, which are available at: https://www.energy.gov/gc/doe-procedures- administrative-adjudication-civil- penalty-actions. 
Proposed § 460.320 provides that after 
considering all matters of record in a proceeding, the ALJ will issue an initial decision. The ALJ’s initial decision will include a statement of the ALJ’s findings and conclusions on all material issues of fact, law, and discretion, as well as the ALJ’s reasons for such findings and conclusions. If the ALJ finds that a manufacturer committed a prohibited act and that a civil penalty is warranted, 
the decision will include the amount of the civil penalty. DOE notes that nothing in this subpart guarantees that a case will proceed to a formal hearing, as an ALJ may issue an initial decision after considering the pleadings and any motions for decision. 
Proposed § 460.320 provides that if 
the ALJ’s initial decision includes a finding that a manufacturer committed a prohibited act and a recommended civil penalty, and the initial decision is not appealed in accordance with DOE’s Procedures for Administrative Adjudication of Civil Penalty Actions, the DOE General Counsel will issue an Order assessing the civil penalty. The DOE General Counsel will include in the Order the ALJ’s findings of fact, conclusions of law and discretion, and the amount of the civil penalty. 
Finally, proposed § 460.320 provides 
that if the ALJ’s initial decision is appealed in accordance with DOE’s Procedures for Administrative Adjudication of Civil Penalty Actions, 
then the DOE Decision Maker will issue a final agency decision in accordance with those procedures. The proposed section deviates from the procedures with respect to judicial review, however, in that it provides that any such final agency decision may be appealed to a federal court with competent jurisdiction instead of to a federal circuit court of appeals. It also provides that only a final agency decision may be appealed to a federal court of competent jurisdiction. 
Collection of Civil Penalties 
DOE proposes that if a manufacturer 
fails to pay an assessed civil penalty 
within 30 days of receipt of the Order assessing the civil penalty, DOE may refer the debt to the U.S. Treasury Department or the Attorney General of the United States, or his or her delegate, for collection of the civil penalty. DOE proposes that in any such action, the validity and appropriateness of the Order assessing the civil penalty will not be subject to review. 
III. Expected Costs to Manufacturers 
From the Proposed Rule 
In the May 2022 Final Rule, DOE 
monetized the costs and benefits expected to result from the amended standards. These costs included costs to manufacturers to produce and transport compliant manufactured homes, the increased installed costs that the consumer would see when purchasing and installing a new manufactured home, along with the incremental utility bill savings and incremental maintenance costs that a consumer would expect to experience during the lifetime operation. At the time of the May 2022 Final Rule, DOE had not determined the specific procedures it would utilize to ensure compliance with the energy conservation standards being adopted, but DOE noted its expectation that only minimal compliance efforts would be required, and that such efforts would result in minimal additional costs to manufacturers. See 87 FR 
23758. Based on the procedures DOE is proposing in this document, DOE tentatively concludes, consistent with the expectations it stated in the May 2022 Final Rule, see Id., that the costs of complying with DOE’s enforcement mechanisms will be minimal. Specifically, in this rulemaking, DOE is not proposing to require manufacturers to conduct any testing of manufactured homes, require manufactured homes to be inspected prior to sale to consumers, or require manufacturers (or any third- party agency) to certify compliance with DOE’s energy conservation standards. Rather, the proposed regulations in this document outline DOE’s procedures for investigating potential instances of noncompliance, assessing civil penalties in accordance with EISA, and the associated appeals procedures. To ensure DOE is able to conduct such investigations, this proposed rule requires that a manufacturer maintain and provide to DOE information and records relevant to investigating and determining compliance with the energy conservation standards. However, the documentation that manufacturers would be required to maintain by § 460.306(a) of this proposed rule is already subject to separate, existing maintenance requirements imposed by HUD. Therefore, this proposed rule would not impose any new, additional costs beyond the costs already required by separate requirements. See 88 FR 
45237. Specifically, DOE is proposing to require manufacturers to maintain the following records in accordance with HUD requirements: the information and records submitted by a manufacturer and approved by its Design Approval Primary Inspection Agency (DAPIA) pursuant to 24 CFR 3282.203(g) and 3282.361(b)(4);
6the approved quality 
assurance manual received from a DAPIA pursuant to 24 CFR

7Id. 
824 CFR 3282.417(e) requires a manufacturer to 
maintain records related to such determinations, 
notifications, and corrections. 
924 CFR 3282.608(n) requires a manufacturer to 
maintain the approval notification from the DAPIA, the manufacturer’s final on-site inspection report and certification of completion, and the Production Inspection Primary Inspection Agency’s acceptance of the final site inspection report and certification. A manufacturer is required to make these records available for review by HUD in the factory of origin. In addition, 24 CFR 3282.608(q) requires a manufacturer to maintain all records for on-site completion for each home, as required by 24 CFR 3282.608, in the unit file to be maintained by the manufacturer. 3282.361(c)(3);7records related to a 
manufacturer’s determination of 
noncompliance, defect, serious defect, or imminent safety hazard, as well as any corrections made by the manufacturer that the manufacturer is required to maintain under 24 CFR 3282.417;
8and records and reports 
related to on-site construction of manufactured homes that the manufacturer is required to maintain pursuant to 24 CFR 3282.608.
9 
In light of the previous, DOE 
tentatively concludes additional costs imposed by this proposed rule would be minimal. For this reason, the adoption of the enforcement procedures proposed in this document would not alter DOE’s assessment in the May 2022 Final Rule of the costs resulting from the adoption of DOE’s energy conservation standards. 
IV. Procedural Issues and Regulatory 
Review 
A. Review Under Executive Orders 
12866, 13563 and 14094 
Executive Order (‘‘E.O.’’) 12866, 
‘‘Regulatory Planning and Review,’’ 58 FR 51735 (Oct. 4, 1993), as supplemented and reaffirmed by E.O. 13563, ‘‘Improving Regulation and Regulatory Review,’’ 76 FR 3821 (Jan. 21, 2011), and amended by E.O. 14094, ‘‘Modernizing Regulatory Review,’’ 88 FR 21879 (April 11, 2023) requires agencies, to the extent permitted by law, to (1) propose or adopt a regulation only upon a reasoned determination that its benefits justify its costs (recognizing that some benefits and costs are difficult to quantify); (2) tailor regulations to impose the least burden on society, consistent with obtaining regulatory objectives, taking into account, among other things, and to the extent practicable, the costs of cumulative regulations; (3) select, in choosing among alternative regulatory approaches, those approaches that maximize net benefits (including potential economic, environmental, public health and safety, and other advantages; distributive impacts; and equity); (4) to the extent feasible, specify 
performance objectives, rather than specifying the behavior or manner of compliance that regulated entities must adopt; and (5) identify and assess available alternatives to direct regulation, including providing economic incentives to encourage the desired behavior, such as user fees or marketable permits, or providing information upon which choices can be made by the public. DOE emphasizes as well that E.O. 13563 requires agencies to use the best available techniques to quantify anticipated present and future benefits and costs as accurately as possible. In its guidance, the Office of Information and Regulatory Affairs (‘‘OIRA’’) within the Office of Management and Budget (OMB) has emphasized that such techniques may include identifying changing future compliance costs that might result from technological innovation or anticipated behavioral changes. For the reasons stated in the preamble, this proposed regulatory action is consistent with these principles. 
B. Review Under the Regulatory 
Flexibility Act 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) requires the 
preparation of an initial regulatory flexibility analysis (IRFA) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by E.O. 13272, Proper Consideration of Small Entities in Agency Rulemaking, 67 FR 53461 (Aug. 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the potential impacts of its rules on small entities are properly considered during the rulemaking process. (68 FR 7990). The Department has made its procedures and policies available on the Office of General Counsel’s website: www.energy.gov/gc/ office-general-counsel. 
The proposed rule would establish 
enforcement procedures for DOE’s manufactured housing energy conservation standards. The proposed 
regulations largely outline DOE’s procedures for investigating instances of noncompliance, assessing civil penalties in accordance with EISA, and associated appeals procedures. DOE expects any costs borne by manufacturers as a result of the proposed rule to be negligible. Moreover, the proposed rule would apply equally across manufacturers and does not place small entities at a significant competitive disadvantage. Accordingly, DOE certifies that this proposed rule would not have a 
significant economic impact on a substantial number of small entities, and, therefore, no regulatory flexibility analysis is required. Accordingly, DOE did not prepare an IRFA for this proposed rulemaking. DOE’s certification and supporting statement of factual basis will be provided to the Chief Counsel for Advocacy of the Small Business Administration for review under 5 U.S.C. 605(b). 
C. Review Under the Paperwork 
Reduction Act of 1995 
The proposed rule would impose no 
new information or record keeping requirements. Accordingly, OMB clearance is not required under the Paperwork Reduction Act. (44 U.S.C. 3501 et seq.) 
D. Review Under the National Environmental Policy Act of 1969 
DOE is analyzing this proposed 
regulation in accordance with the National Environmental Policy Act of 
1969 (‘‘NEPA’’) and DOE’s NEPA implementing regulations (10 CFR part 1021). DOE’s regulations include a categorical exclusion for amending an existing rule or regulation that does not change the environmental effect of the rule or regulation being amended. 10 CFR part 1021, subpart D, appendix A5. DOE anticipates that this rulemaking qualifies for categorical exclusion A5 because it is a rulemaking that is amending an existing rule or regulation that does not change the environmental effect of the rule or regulation being amended, and categorical exclusion A6, because it is procedural. No extraordinary circumstances exist that require further environmental analysis, and it otherwise meets the requirements for application of a categorical exclusion. See 10 CFR 1021.410. 
Accordingly, neither an environmental assessment nor an environmental impact statement is required. 
E. Review Under Executive Order 13132 
Executive Order 13132, ‘‘Federalism,’’ 
64 FR 43255 (Aug. 10, 1999), imposes 
certain requirements on agencies formulating and implementing policies or regulations that preempt State law or that have federalism implications. The Executive order requires agencies to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and to carefully assess the necessity for such actions. The E.O. also requires agencies to have an accountable process to ensure meaningful and timely input by State and local officials in the development of regulatory policies that 
VerDate Sep<11>2014 16:17 Dec 22, 2023 Jkt 262001 PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 E:\FR\FM\26DEP1.SGM 26DEP1khammond on DSKJM1Z7X2PROD with PROPOSALS88850 Federal Register / Vol. 88, No. 246 / Tuesday, December 26, 2023 / Proposed Rules 
have federalism implications. On March 
14, 2000, DOE published a statement of policy describing the intergovernmental consultation process it will follow in the development of such regulations. (See 65 FR 13735.) DOE examined this proposed rule and determined that it would not preempt State law and would not have a substantial direct effect on the 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. No further action is required by E.O. 13132. 
F. Review Under Executive Order 12988 
With respect to the review of existing 
regulations and the promulgation of 
new regulations, section 3(a) of E.O. 12988, ‘‘Civil Justice Reform,’’ 61 FR 4729 (Feb. 7, 1996), imposes on Federal agencies the general duty to adhere to the following requirements: (1) eliminate drafting errors and ambiguity; (2) write regulations to minimize litigation; and (3) provide a clear legal standard for affected conduct, rather than a general standard and promote simplification and burden reduction. Section 3(b) of E.O. 12988 specifically requires that executive agencies make every reasonable effort to ensure that the regulation: (1) clearly specifies its preemptive effect, if any; (2) clearly specifies any effect on existing Federal law or regulation; (3) provides a clear legal standard for affected conduct, while promoting simplification and burden reduction; (4) specifies its retroactive effect, if any; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under any 
guidelines issued by the Attorney General. Section 3(c) of E.O. 12988 requires executive agencies to review regulations in light of applicable standards in section 3(a) and section 3(b) to determine whether they are met, or it is unreasonable to meet one or more of them. DOE has completed the required review and determined that, to the extent permitted by law, the proposed rule would meet the relevant standards of E.O. 12988. 
G. Review Under the Unfunded 
Mandates Reform Act of 1995 
Title II of the Unfunded Mandates 
Reform Act of 1995 (UMRA) (Pub. L. 104–4) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and tribal governments and the private sector. For a proposed regulatory action likely to result in a rule that may cause the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector of $100 million or more 
in any one year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish a written statement that estimates the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a) and (b)). The section of UMRA also requires a Federal agency to develop an effective process to permit timely input by elected officers of State, local, and tribal governments on a proposed ‘‘significant intergovernmental mandate’’ and requires an agency plan for giving notice and opportunity for timely input to potentially affected small governments before establishing any requirements that might significantly or uniquely affect small governments. On March 18, 1997, DOE published a statement of policy on its process for 
intergovernmental consultation under UMRA (62 FR 12820) (also available at www.energy.gov/gc/office-general- counsel). This proposed rule contains neither an intergovernmental mandate nor a mandate that may result in the expenditure of $100 million or more in any year by State, local, and tribal governments, in the aggregate, or by the private sector, so these requirements under the Unfunded Mandates Reform Act do not apply. 
H. Review Under the Treasury and 
General Government Appropriations Act of 1999 
Section 654 of the Treasury and 
General Government Appropriations Act of 1999 (Pub. L. 105–277) requires Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well-being. This proposed rule would not have any impact on the autonomy or integrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking Assessment. 
I. Review Under Executive Order 12630 
DOE has determined, under E.O. 
12630, ‘‘Governmental Actions and 
Interference with Constitutionally Protected Property Rights,’’ 53 FR 8859 (Mar. 18, 1988), that this proposed rule would not result in any takings which might require compensation under the Fifth Amendment to the United States Constitution. 
J. Review Under the Treasury and 
General Government Appropriations Act, 2001 
Section 515 of the Treasury and 
General Government Appropriations Act, 2001 (44 U.S.C. 3516, note) provides for agencies to review most disseminations of information to the public under guidelines established by each agency pursuant to general guidelines issued by OMB. OMB’s guidelines were published at 67 FR 8452 (February 22, 2002), and DOE’s guidelines were published at 67 FR 62446 (October 7, 2002). DOE has reviewed the proposed rule under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines. 
K. Review Under Executive Order 13211 
Executive Order 13211, ‘‘Actions 
Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use,’’ 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to OIRA, a Statement of Energy Effects for any proposed significant energy action. A ‘‘significant energy action’’ is defined as any action by an agency that promulgated or is expected to lead to promulgation of a final rule, and that: (1) is a significant regulatory action under E.O. 12866, or any successor order; and (2) is likely to have a significant adverse effect on the supply, distribution, or use of energy, or (3) is designated by the Administrator of OIRA as a significant energy action. For any proposed significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use should the proposal be implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use. This proposed rule establishes enforcement procedures for DOE’s manufactured housing energy conservation standards and therefore does not meet the second criterion. Additionally, OIRA has not designated this proposed rule as a significant energy action. Accordingly, the requirements of E.O. 13211 do not apply. 
V. Public Participation Submission of Comments
