29 CFR Part 1910

[Docket No. OSHA-2007-0040]
RIN 1218-AC08

 
Updating OSHA Standards Based on National Consensus Standards

AGENCY: Occupational Safety and Health Administration (OSHA); 
Department of Labor.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: In this Notice of Proposed Rulemaking (NPRM), the Agency is 
proposing to remove several references to consensus standards that have 
requirements that duplicate or are comparable to other OSHA rules; this 
rulemaking also includes correcting a paragraph citation in one these 
OSHA rules. In addition, the Agency is proposing to remove the 
reference to American Welding Society standard A3.0-1969 ("Terms and 
Definitions") in its general-industry welding standards. OSHA also is 
publishing a direct final rule in today's Federal Register taking these 
same actions. This NPRM is the companion document to the direct final 
rule. This rulemaking is a continuation of OSHA's ongoing effort to 
update references to consensus and industry standards used throughout 
its rules.

DATES: Comments to this NPRM (including comments to the information-
collection (paperwork) determination described under the section titled 
SUPPLEMENTARY INFORMATION of companion direct final rule), hearing 
requests, and other information must be submitted by January 14, 2008. 
All submissions must bear a postmark or provide other evidence of the 
submission date. (See the following section titled ADDRESSES for 
methods you can use in making submissions.)

ADDRESSES: Comments and hearing requests may be submitted as follows:
     Electronic. Comments may be submitted electronically to 
http://www.regulations.gov, which is the Federal eRulemaking Portal. 

Follow the instructions online for submitting comments.
     Facsimile. OSHA allows facsimile transmission of comments 
and hearing requests that are 10 pages or fewer in length (including 
attachments). Send these documents to the OSHA Docket Office at (202) 
693-1648; hard copies of these documents are not required. Instead of 
transmitting facsimile copies of attachments that supplement these 
documents (e.g., studies, journal articles), commenters must submit 
these attachments, in triplicate hard copy, to the OSHA Docket Office, 
Technical Data Center, Room N-2625, OSHA, U.S. Department of Labor, 200 
Constitution Ave., NW., Washington, DC 20210. These attachments must 
clearly identify the sender's name, date, subject, and docket number 
(i.e., OSHA-2007-0040) so that the Agency can attach them to the 
appropriate document.
     Regular mail, express delivery, hand (courier) delivery, 
and messenger service. Submit three copies of comments and any 
additional material (e.g., studies, journal articles) to the OSHA 
Docket Office, Docket No. OSHA-2007-0040 or RIN No. 1218-AC08, 
Technical Data Center, Room N-2625, OSHA, U.S. Department of Labor, 200 
Constitution Ave., NW., Washington, DC 20210; telephone: (202) 693-
2350. (OSHA's TTY number is (877) 889-5627.) Note that security-related 
problems may result in significant delays in receiving comments and 
other written materials by regular mail. Please contact the OSHA Docket 
Office for information about security procedures concerning delivery of 
materials by express delivery, hand delivery, and messenger service. 
The hours of operation for the OSHA Docket Office are 8:15 a.m. to 4:45 
p.m., e.t.
     Instructions. All submissions must include the Agency name 
and the OSHA docket number (i.e., OSHA Docket No. OSHA-2007-0040). 
Comments and other material, including any personal information, are 
placed in the public docket without revision, and will be available 
online at http://www.regulations.gov. Therefore, the Agency cautions 
commenters about submitting statements they do not want made available 
to the public, or submitting comments that contain personal information 
(either about themselves or others) such as social security numbers, birth 
dates, and medical data.
    OSHA requests comments on all issues related to this NPRM. It also 
welcomes comments on its findings that there would be no negative 
economic, paperwork, or other regulatory impacts of this NPRM on the 
regulated community. This NPRM is the companion document to a direct 
final rule also published in today's Federal Register. If OSHA receives 
no significant adverse comment on the companion direct final rule, it 
will publish a Federal Register document confirming the effective date 
of the direct final rule and withdrawing this NPRM. Such confirmation 
may include minor stylistic or technical corrections to the document. 
For the purpose of judicial review, OSHA considers the date that it 
confirms the effective date of the direct final rule to be the date of 
issuance. However, if OSHA receives significant adverse comment on the 
direct final rule, it will publish a timely withdrawal of the direct 
final rule and proceed with this NPRM addressing the same standards.

the docket, go to http://www.regulations.gov or to the OSHA Docket 
Office at the address above. Documents in the docket are listed in the

SUPPLEMENTARY INFORMATION: 

I. Discussion of the Proposal

    OSHA is proposing to remove several references to outdated 
consensus standards in its general-industry rules that have 
requirements that duplicate or are comparable to other OSHA rules. In 
addition, the Agency is correcting a paragraph citation in one these 
OSHA rules. The Agency also proposes to remove the reference to 
American Welding Society standard A3.0-1969 ("Terms and Definitions") 
in its general-industry welding standards. This NPRM is the companion 
document to a direct final rule concerning the same standards published 
in the "Rules" section of today's Federal Register. For a complete 
discussion of this action, the relevant consensus standards and OSHA 
standards affected by this NPRM, as well as a discussion of the 
economic analysis and Regulatory Flexibility Act certification, 
paperwork determination, issues involving federalism and State-Plan 
States, and OSHA's response under the Unfunded Mandates Reform Act, see 
the preamble to the direct final rule.

II. Public Participation

    OSHA requests comments on all issues related to this NPRM. The 
Agency also welcomes comments on its findings that this rulemaking 
would have no negative economic or other regulatory impacts of this 
NPRM on the regulated community. If OSHA receives no significant 
adverse comment, it will publish a Federal Register document confirming 
the effective date contained in the companion direct final rule and 
withdrawing this NPRM. Such confirmation may include minor stylistic or 
technical corrections to the document. A full discussion of what 
constitutes a significant adverse comment is contained in the companion 
direct final rule.
    The Agency will withdraw the direct final rule if it receives 
significant adverse comment on the amendments contained in the direct 
final rule, and proceed with this NPRM by addressing the comment and 
publishing a new final rule. Should the Agency receive a significant 
adverse comment regarding some actions taken in the direct final rule, 
but not others, it may (1) finalize those actions that did not receive 
significant adverse comment, and (2) conduct further rulemaking under 
this NPRM for the actions that received significant adverse comment. 
The comment period for this NPRM runs concurrently with that of the 
direct final rule. Therefore, any comments received under this NPRM 
will be treated as comments regarding the direct final rule. Likewise, 
significant adverse comments submitted to the direct final rule will be 
considered as comments to this NPRM; the Agency will consider such 
comments in developing a subsequent final rule.
    Comments received will be posted without change to http://www.regulations.gov,
including any personal information provided. 

Accordingly OSHA cautions commenters about submitting personal 
information such as social security numbers and birth dates.
