The U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) has prepared a draft environmental impact statement (EIS) for proposed energy conservation standards for manufactured housing.

Background

The Energy Independence and Security Act of 2007 (EISA) directs DOE to establish energy conservation standards for manufactured housing based on the most recent version of the International Energy Conservation Code (IECC). EERE issued a Supplemental Notice of Proposed Rulemaking (SNOPR) on August 26, 2021, that proposed energy conservation standards for manufactured housing based on the 2021 IECC. DOE’s proposed standards relate to the building thermal envelope; air sealing; installation of insulation; duct sealing; heating, ventilation and air conditioning (HVAC); service hot water systems; mechanical ventilation fan efficacy; and heating and cooling equipment sizing.

On October 26, 2021, in consideration of relevant information that had recently become available and in response to inputs received, DOE published a notification of data availability (NODA) for the manufactured housing energy conservation standards rulemaking. The analyses in the NODA included an update to the manufacturer's retail list price threshold for the tiered standards based on price, to reflect more recent data. Further, the NODA presented a sensitivity analysis in response to comments (including public comments received during EIS scoping) that used an alternate tiered approach based on size (i.e., single-section versus multi-section manufactured housing). DOE also performed a sensitivity analysis with alternate wall insulation requirements for climate zones 2 and 3 for both the tiered and the untiered standards.

DOE's proposed action would use a price-based tiered approach to address affordability and cost-effectiveness concerns with respect to energy cost savings and the cost of efficiency improvements relative to the retail list price of manufactured housing. DOE is also considering alternatives that use the size-based tiered approach (which also addresses affordability and cost effectiveness) and the untiered approach. Within these three approaches – tiered standards based on price, tiered standards based on size, and untiered standards – DOE is also considering options for exterior wall insulation requirements.

DOE has prepared the draft EIS to provide information to the public and to inform the final rulemaking to establish energy conservation standards for manufactured housing. The draft EIS presents information about the proposed action and alternatives; potential impacts to the human environment of the proposed action and alternatives; potential adverse environmental effects that cannot be avoided; and measures to mitigate potential adverse impacts.

Specifically, the draft EIS presents information about potential impacts related to: (1) energy resources; (2) air resources, including emissions of greenhouse gases and other pollutants, climate change, ambient air quality, and indoor air quality; (3) health and safety; (4) socioeconomics; and (5) environmental justice. The draft EIS also includes a summary of the information and analyses submitted by commenters during the scoping period for consideration by DOE in developing the EIS.


Draft EIS

Public Comment Opportunity for the Draft EIS

The notice of availability (NOA) for the draft EIS was published in the Federal Register on January 14, 2022. The public comment period for the draft EIS is open through February 28, 2022.

Public Meetings on the Draft EIS

The U.S. Department of Energy (DOE) will hold two virtual public meetings for the draft EIS on proposed energy conservation standards for manufactured housing at the following dates/times. DOE invites the public to provide comments on the analyses presented in the draft EIS. Those who would like to provide an oral comment on the draft EIS are asked to register by clicking on the “Register to Speak” button below, selecting the specific meeting(s) in which they wish to participate.

Please register if you would like to provide oral comments on the draft EIS during a meeting. Each speaker will have 5 minutes to present their comment(s).

An agenda will be provided in advance of the meetings.

Submitting Comments on the Draft EIS

DOE is seeking input from all interested stakeholders on the draft EIS. All parties may provide oral and/or written comments on the draft EIS for 45 days from publication of the NOA for the draft EIS in the Federal Register. Comments on the draft EIS are invited through February 28, 2022. Methods for submitting both oral and written comments are described below.

Comments should be directly relevant to the draft EIS, in accordance with the National Environmental Policy Act (NEPA) process. For example, these comments might relate to potential environmental impacts or mitigation measures.

Submitting Oral Comments

Individuals interested in providing oral comments on the draft EIS should register in advance of the public meetings, by selecting the specific meeting(s) in which they wish to participate (see above). Both public meetings will be recorded, and the record of each meeting will be made available on this website following the meetings. To appropriately document the comments received, each participant providing an oral comment during the public meeting will be asked to state and spell their name, and if representing an organization, to also identify that affiliation. Each speaker will have 5 minutes to present their comment(s) on the draft EIS.

Submitting Written Comments

The preferred method for submission of written comments is through this website's comment form. To submit an online comment on the draft EIS, please use the button below. Comment Form

If you cannot use the online comment form, written comments will be accepted by mail. Written comments may be mailed to:
NEPA Document Manager
DOE Golden Field Office

Golden, CO 80401

How Your Comments on the Draft EIS Will Be Used

The final EIS (which will be available on this website when completed) will include a summary of the information and analyses submitted during the comment period on the draft EIS for consideration by DOE in preparing the final EIS. Comments received on the draft EIS will be used to help inform DOE’s decision-making process for establishing energy conservation standards for manufactured housing.

DOE provides reasonable accommodation to individuals with disabilities as appropriate. If such accommodation is needed to participate in a meeting, or if a meeting notice or other information from this meeting is needed in another format (e.g., Braille, or large print), please notify the DOE contact by email ([email protected]) or by mail (NEPA Document Manager, DOE Golden Field Office, 15013 Denver West Parkway, Golden, CO 80401). Determinations on requests for reasonable accommodation will be made on a case-by-case basis.


Scoping Period

DOE sought input from all interested stakeholders on the scope of the EIS for 30 days after the Notice of Intent (NOI) to prepare an EIS was published in the Federal Register (July 7, 2021 through August 6, 2021.) Comments directly relevant to the scope of the EIS were invited, in accordance with the National Environmental Policy Act (NEPA) process.

In July 2021, DOE held two public scoping meetings at which DOE presented preliminary information on the scope of the EIS and invited oral comments. The recordings of these meetings are available on YouTube via the links below.

(Note: Comments were not taken on the proposed rule for energy conservation standards as part of the EIS scoping process, because those inputs were sought under a separate process. After the SNOPR was issued on August 26, 2021, DOE held one public webinar, and there was a 60-day public comment period during which DOE invited public comments on the proposed rule. With publication of the NODA on October 26, 2021, the public comment period was extended until November 27, 2021.)
