All comments, including any The Department of Labor, as part of its continuing effort to reduce paperwork and respondent (i.e., employer) burden, conducts a preclearance consultation program to provide the public with an opportunity to comment on proposed and continuing information collection requirements in accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3506(c)(2)(A)). This program ensures that information is in the desired format, reporting burden (time and costs) is minimal, collection instruments are clearly understood, and OSHA’s estimate of the information collection burden is accurate. The Occupational Safety and Health Act of 1970 (the OSH Act) (29 U.S.C. 651 et seq.) authorizes information collection by employers as necessary or appropriate for enforcement of the Act or for developing information regarding the causes and prevention of occupational injuries, illnesses, and accidents (29 U.S.C. 657). The OSH Act also requires that OSHA obtain such information with minimum burden upon employers, especially those operating small businesses, and to reduce to the maximum extent feasible unnecessary duplication of efforts in obtaining information (29 U.S.C. 657). Paragraph (a)(4) of the Standard requires that employers obtain the SUMMARY: srobinson on DSKHWCL6B1PROD with NOTICES DATES: VerDate Mar<15>2010 17:52 Apr 19, 2011 Jkt 223001 PO 00000 Frm 00080 Fmt 4703 Sfmt 4703 manufacturer’s written approval before modifying a truck in a manner that affects its capacity and safe operation; if the manufacturer grants such approval, the employer must revise capacity, operation, and maintenance instruction plates, tags, and decals accordingly. For front-end attachments not installed by the manufacturer, paragraph (a)(5) mandates that employers provide a marker on the trucks that identifies the attachment, as well as the weight of both the truck and the attachment when the attachment is at maximum elevation with a laterally centered load. Paragraph (a)(6) specifies that employers must ensure that the markers required by paragraphs (a)(3) through (a)(5) remain affixed to trucks and are legible. Paragraphs (l)(1) through (l)(6) of the Standard contain the paperwork requirements necessary to certify the training provided to powered industrial truck operators.

procedures for examining the trailing cable to ensure the cables are in 
safe operating condition by a visual inspection of the entire cable, 
observing the insulation, the integrity of splices, nicks and 
abrasions. The petitioner further states that if regulations are 
subsequently promulgated that supersede the requirements of 30 CFR 
75.503 (18.35(a)(5)(i), the standard, unless it is determined by the 
Secretary or his representative after opportunity for input from the 
operator that the alternative method contained in the petition will at 
all times guarantee no less than the same measure of protection 
afforded the subsequent promulgated standard. The petitioner asserts 
that the proposed alternative method will provide for a level of safety 
equal to or greater than the statute in place.
