[Docket No. FR 4376-P-01]
RIN 2502-AH23


Manufactured Home Construction and Safety Standards

AGENCY: Office of the Assistant Secretary for Housing--Federal Housing 
Commissioner, HUD.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: HUD is proposing to amend the Federal Manufactured Home 
Construction and Safety Standards (FMHCSS) to update many of the 
standards that are incorporated by reference therein. These reference 
standards, which are developed by voluntary consensus or industry 
groups, provide necessary technical standards for the FMHCSS. These 
proposed amendments would keep the FMHCSS current with the industries 
that use these reference standards by incorporating the latest edition 
of these standards and new relevant standards.

DATES: Comment Due Date: December 29, 1998.

ADDRESSES: Interested persons are invited to submit comments regarding 
this proposed rule to the Rules Docket Clerk, Office of the General 
Counsel, Room 10276, Department of Housing and Urban Development, 451 
Seventh Street SW, Washington, DC 20410. Communications should refer to 
the above docket number and title. A copy of each communication 
submitted will be available for public inspection and copying between 
7:30 a.m. and 5:30 p.m. weekdays at the above address. Facsimile (FAX) 
comments will not be accepted.

FOR FURTHER INFORMATION CONTACT: David R. Williamson, Director, Office 
of Consumer and Regulatory Affairs, Room 9156, Department of Housing 
and Urban Development, 451 Seventh Street SW, Washington, DC 20410; 
telephone (202) 708-6423 (this is not a toll-free number). Persons with 
hearing or speech impairments may access that number toll-free via TTY

SUPPLEMENTARY INFORMATION:

I. Background

    The National Manufactured Housing Construction and Safety Standards 
Act of 1974 (42 U.S.C. 5401 et seq.) (the Act) authorizes the Secretary 
of HUD to establish and amend the Federal Manufactured Home 
Construction and Safety Standards (the Standards), codified in 24 CFR 
part 3280. The purposes of the Act are ``to reduce the number of 
personal injuries and deaths and the amount of insurance cost and 
property damage resulting from manufactured home accidents and to 
improve the quality and durability of manufactured homes'' (42 U.S.C. 
5401). Additionally, OMB Circular A-119, as revised on February 19, 
1998 (63 FR 8546) for consistency with the National Technology Transfer 
and Advancement Act of 1995 (Pub. L. 104-113; 110 Stat. 775) (NTTAA), 
requires Federal agencies to use appropriate technical standards that 
are developed or adopted by private sector standards entities. Section 
15(b)(7) of OMB Circular A-119 encourages agencies to review, in a 
timely manner, their regulations that may reference obsolete and 
outdated standards. In accordance with the Act and these purposes, HUD 
is issuing these proposed amendments to the FMHCSS for public comment.
    Through this proposed rule, HUD identifies those standards 
incorporated by reference in the FMHCSS for which it has evaluated 
updated voluntary consensus and industry standards and recommends 
adoption of updated standards in accordance with section 11 of OMB 
Circular A-119. This proposed rule only includes updates for those 
reference standards for which HUD is ready to accept a more recent 
edition. In those areas for which this rule is not proposing a more 
recent edition, HUD considers future rulemaking to be more appropriate. 
HUD intends to review the currency and applicability of the 
incorporated reference standards regularly, and to prepare proposed 
amendments to update them on a 2-year cycle. Where a reference standard 
change would impose additional compliance burdens or affect the 
performance of the homes, HUD will always consider the advisability of 
separate rulemaking.
    Since these proposed amendments only involve reference standards, 
the presentation of the changes and discussion is in the form of 
tables. These tables will list the reference standards by their 
designation, edition date, title, and the sections of the FMHCSS in 
which it can be found. Table 1 lists all the reference standards 
currently in the FMHCSS. Table 2 lists all the reference standards that 
this rule proposes to include in the FMHCSS. An indicator with each 
reference standard will provide the action being taken on each standard 
by this proposed rule. Table 3 lists those organizations providing the 
reference standards to be incorporated. Table 4 lists new reference 
standards that previously were not referenced in the FMHCSS, and 
provides specific comments about some of the standards. (Note: The 
reference standards in Table 4 are also listed in Table 2.) Table 5 
lists those reference standards that would be deleted from the FMHCSS.

II. Comments Requested

    This proposed rule invites public comment prior to the final 
issuance of changes to the standards referenced in part 3280. 
Commenters are urged to identify and address the particular standards 
for which comment is being submitted. Commenters also may offer 
suggestions for more appropriate or more current substitutions of 
specific proposed standards.

III. Reference Standards Currently In Effect (Table 1)

    Table 1 lists those reference standards currently in effect in the 
FMHCSS. The last column in Table 1 indicates those sections of part 
3280 in which the applicable standard is referenced.

IV. Proposed Changes To Reference Standards (Table 2)

    Table 2 is the list of updated standards being proposed. Those 
reference standards that would be deleted from HUD's incorporation by 
reference do not appear in this table; however, they are listed, along 
with the reason for deletion, in Table 5. When the most recent edition 
of a reference standard is being proposed, it is indicated by a ``U.'' 
If the current edition would be retained because it is the most 
current, it is indicated by a ``NC.'' Updated reference standards that 
would impose new or significantly altered requirements are on hold and 
are indicated by ``H.'' New reference standards proposed to be 
incorporated are indicated by an ``N''; the new standards are listed in 
Table 5. The indicator is located just above the first letter of the 
standards designation.

VI. New Reference Standards (Table 4)

    In order to remain abreast of the industries that use those 
reference standards incorporated into the FMHCSS, and to be in accord 
with section 11 of OMB Circular A-119, HUD is proposing to incorporate 
the latest edition of those reference standards and incorporate new 
relevant reference standards. However, this proposed rule only includes 
updates for those reference standards for which HUD is ready to accept 
a more recent edition. In those areas for which this rule is not 
proposing a more recent edition, HUD considers future rulemaking to be 
more appropriate. Those new reference

[[Page 58583]]

standards not previously incorporated into the FMHCSS are listed in 
Table 4. Those reference standards being deleted from the FMHCSS are 
listed in Table 5.

                                                Table 4.--List of New Reference Standards Being Proposed
--------------------------------------------------------------------------------------------------------------------------------------------------------
AAMA/NWWDA 101/I.S.2- 97................         1997  Voluntary Specifications for Aluminum, Vinyl (PVC)   3280.304(b)(1).
                                                        and Wood Windows and Glass Doors.                   3280.405(c)(2).
  The AAMA/NWWDA 101/I.S.2-97 standard would replace the NWWDA standards I.S.1, .2, .3, and .4.
AAMA 1600...............................         1990  Voluntary Specification for Skylights..............  3280.403(b).
ANSI/NSF 61.............................         1997  Drinking Water Systems Components-Health Effects...  3280.604(b)(2).
  The requirements of the ANSI/NSF 61 standard were previously part of NSF 14, but would now be addressed separately.
ASSE 1051...............................         1996  Air Admittance Valves for Plumbing Drainage Systems- 3280.604.
                                                        Fixture and Branch Devices.                         3280.611(d).
  The ASSE 1051 standard would provide an alternative to the prescriptive requirements for anti-siphon trap vent devices that are specified in Sec.
3280.611(d).
ANSI A208.2.............................         1994  Medium Density Fiberboard..........................  3280.304(b)(1).
  The ANSI A208.2 standard would incorporate the MDF standard that is used by the industry and establish it as the base level for the performance of
this product. It would also codify a mandatory formaldehyde emission level for MDF. However, as this standard is currently being used by the industry,
its incorporation is not believed to have either an economic or environmental impact.
ASTM C920-95............................         1995  Standard Specification for Elastomeric Joint         3280.611(d)(5).
                                                        Sealants.
ASTM F876-96............................         1996  Standard Specification for Crosslinked Poluethylene  3280.604(a).
                                                        (PEX) Tubing.
ASTM F877-96............................         1996  Standard Specification for Crosslinked Poluethylene  3280.604(a)
                                                        (PEX) Plastic Hot and Cold Water Distribution
                                                        Systems.
ASTM F1807-97...........................         1997  Specification for Metal Insert Fittings Utilizing a  3280.604(a).
                                                        Copper Crimp Ring for SDR-9 Crosslinked
                                                        Polyethylene Tubing.
  ASTM F876, F877, and F1807 are being incorporated to provide an appropriate reference for the Crosslinked Polyethylene (PEX) systems currently being
installed in manufactured homes. Present PEX installations require that HUD and DAPIAs verify that each system, which is the tubing and specific
connectors, is listed for its intended use. With the availability of an appropriate fitting standard, this should no longer be necessary in all cases.
Where fittings other than the metal insert type are desired, an appropriate listing of the system would still be required. HUD will consider
incorporating other fitting standards recommended in response to this proposed rule change.
NFRC-100................................         1997  Procedure for Determining Fenestration Product U     3280.508(e).
                                                        Factors April 1997 Edition.
  The NFRC-100 standard would provide an alternative for those window manufacturers who used this method in order to comply with the mandatory
requirements of other programs.
PS 20...................................         1994  American Softwood Lumber Standard..................  3280.304(b)(1).
UL 2021.................................         1997  Fixed and Location-Dedicated Electric Room Heaters.  3280.703.
                                                                                                            *Replaces UL 1025-1991

VII. Findings and Certifications

A. Unfunded Mandates Reform Act

    This rule does not impose any Federal mandates on any State, local, 
or tribal governments, or on the private sector, within the meaning of 
the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4; approved March 
22, 1995).

B. Impact on the Environment

    A Finding of No Significant Impact with respect to the environment 
was made in accordance with HUD regulations in 24 CFR part 50 that 
implement section 102(2)(C) of the National Environmental Policy Act of 
1969 (42 U.S.C. 4223). The Finding is available for public inspection 
between 7:30 a.m. and 5:30 p.m. weekdays in the Office of the Rules 
Docket Clerk, Office of General Counsel, Room 10276, Department of 
Housing and Urban Development, 451 Seventh Street SW, Washington, DC 
20410.

C. Impact on Small Entities

    The Secretary, in accordance with the Regulatory Flexibility Act (5 
U.S.C. 605(b)), has reviewed this proposed rule before publication and 
by approving it certifies that this rule is not anticipated to have a 
significant economic impact on a substantial number of small entities. 
HUD has evaluated the potential effects of this proposed rule and 
determined that it would not place major burdens on manufactured home 
manufacturers or their suppliers. In its evaluation, HUD noted that new 
or updated references are being proposed only for the purpose of 
remaining abreast of the manufactured home industry. The inclusion of 
reference standard changes that would impose significant new 
requirements is not being addressed with this proposed rule. While HUD 
does not anticipate that this proposed rule would have a significant 
economic impact on a substantial number of small entities, HUD 
specifically requests comments regarding alternatives to compliance 
that may be less burdensome on such entities.

D. Federalism Impact

    The General Counsel, as the Designated Official under section 6(a) 
of Executive Order 12612, Federalism, has determined that the policies 
contained in this proposed rule are covered by section 604(d) of the 
National Manufactured Housing Construction and Safety Standards Act of 
1974, and therefore, would not have substantial direct effects on 
States or their political subdivisions, or the relationship between the 
Federal Government and the States, or on the distribution of power and 
responsibilities among the various levels of government. As a result, 
the rule is not subject to review under the Order.

VIII. Incorporation by Reference

    Before HUD issues a final rule, these reference standards will be 
approved by the Director of the Federal Register for incorporation by 
reference in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies 
of these standards may be obtained from the organizations listed in 
Table 3.

Catalog of Federal Domestic Assistance

    The Catalog of Federal Domestic Assistance number for Manufactured 
Home Construction and Safety Standards is 14.171.
