the MHCCs recommendations in the current rulemaking and HUDs delay further risks the health and financial well-being of new manufactured home residents.
Another commenter continued that HUD states that given this DOE
rulemaking, it has decided to postpone action on certain MHCC
recommendations affecting 3280.502
and 3280.506b. The proposed rule cites no legal authority for this postponement, nor is HUDs proposed action one of the three outcomes permitted by the statutory text: 11 The adoption, modification, or rejection of the proposed revisions recommended by the MHCC. Moreover, the proposed rule does not fulfill HUDs obligation to publish for public comment the proposed revised standards recommended by the MHCC. Because HUD has failed to identify the specific changes to the Standards that it is postponing, HUD denies the public an opportunity to meaningfully comment on this aspect of the proposed rule.
Even if DOEs standards for energy efficiency would ultimately supersede the MHCCs approved recommendations, HUD has ample time to implement the MHCCs recommended energy efficiency improvements before compliance with any conflicting DOE standards would be required.
Another commenter recognized the valuable role energy efficiency requirements play in reducing the energy burden of households particularly low-and moderate-income households and supporting affordability across the life cycle of homeownership and rental. DOEs delay does not absolve HUD of its obligation to provide manufactured homeowners with energy efficient homes. The commenter recommended HUD
incorporate provisions of the International Energy Conservation Code appropriate for manufactured homes into the federal standards. HUD should also work diligently with DOE to assure the implementation of the requirements in 42 U.S.C. 17071.
HUD Response: HUD reviewed the comments and intends to move forward with more recent MHCC
recommendations. HUD will continue to collaborate and cooperate with other federal agencies, including DOE, as needed and necessary.
IV. Incorporation by Reference The reference standards proposed for incorporation are approved by the Director of the Federal Register for 11 See

incorporation by reference in accordance with 5 U.S.C. 552a and 1
CFR part 51. Copies of these standards may be obtained from the organization that developed the standard. As described in 3280.4, these standards are also available for inspection at HUDs Office of Manufactured Housing Programs and the National Archives and Records Administration.
This final rule incorporates by reference the following six consensus standards for Manufactured Housing:
1. ANSI/ASHRAE 62.22010, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. This standard defines the roles of and minimum requirements for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality in low-rise residential buildings. It is ASHRAEs Indoor Air Quality standard for residential buildings. It applies to spaces intended for human occupancy within singlefamily houses and multi-family structures of three stories or fewer above grade, including manufactured and modular houses. This standard is available online for review via readonly, electronic access at http
ibr.ansi.org/Standards/.
2. ANSI/UL 20342016. Standard for Single and Multiple Station Carbon Monoxide Alarms. These requirements cover electrically operated single and multiple station carbon monoxide CO
alarms intended for protection in ordinary indoor locations of dwelling units, including recreational vehicles, mobile homes, and recreational boats with enclosed accommodation spaces and cockpit areas. The carbon monoxide alarms covered by these requirements are intended to respond to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired appliances, and fireplaces. Carbon monoxide alarms are intended to alarm at carbon monoxide levels below those that cause a loss of ability to react to the dangers of carbon monoxide exposure. Carbon monoxide alarms covered by this standard are not intended to alarm when exposed to long-term, low-level carbon monoxide exposures or slightly higher short-term transient carbon monoxide exposures, possibly caused by air pollution or properly installed and maintained fuelfired appliances and fireplaces.

ibr.ansi.org/Standard.

standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.

LIBRARY.
4. NFPA 702005. National Electrical Code, Article 550.17. The provisions of this article cover the electrical conductors and equipment installed within or on mobile and manufactured homes, the conductors that connect mobile and manufactured homes to a supply of electricity, and the installation of electrical wiring, luminaires fixtures, equipment, and appurtenances related to electrical installations within a mobile home park up to the mobile home service-entrance conductors or, if none, the mobile home service equipment. More specifically, Article 550.17 provides that the wiring of each mobile home be subjected to a 1-minute, 900-volt, dielectric strength test with all switches closed between live parts including neutral and the mobile home ground. Alternatively, the standard allows a test to be performed at 1080 volts for 1 second. This test shall be performed after branch circuits are complete and after luminaires fixtures or appliances are installed.

5. NFPA 720. Standard for the Installation of Carbon Monoxide CO
Detection and Warning Equipment. This document does not attempt to cover all equipment, methods, and requirements that might be necessary or advantageous for the protection of lives from carbon monoxide exposure. The effects of exposure to carbon monoxide vary significantly among different people.
Infants, pregnant women, and people with physical conditions that limit their bodies ability to use oxygen can be affected by low concentrations of carbon monoxide. These conditions include, but are not limited to, emphysema, asthma, and heart disease, all of which are usually indicated by a shortness of breath upon mild exercise. People in need of warning about low levels of carbon monoxide should explore the use of specially calibrated units or other alternatives. This standard is primarily concerned with life safety, not with protection of property. It covers the selection, design, application, installation, location, performance, inspection, testing, and maintenance of
