# SUPPLEMENTARY INFORMATION:

## I. Background

                    On December 23, 2010, PHMSA published an advance notice of proposed rulemaking (ANPRM; 75 FR 80765) seeking public comment on the possible incorporation of the most recent edition of the ASME's                     *Boiler and Pressure Vessel Code, Section XII*                     for the design, construction, and certification of cargo tank motor vehicles, cryogenic portable tanks and multi-unit-tank car tanks (ton tanks) and the National Board of Boiler and Pressure Vessel Inspectors' (National Board)                     *National Board Inspection Code*                     as it applies to the continuing qualification and maintenance of ASME stamped cargo tank motor vehicles, portable tanks, and multi-unit-tank car tanks (ton tanks) constructed to standards in ASME Section VIII or ASME Section XII. PHMSA received comments regarding the availability of the consensus standards referenced in the ANPRM and requesting a comment period extension.                

## II. Availability of Consensus Standards

Several commenters (National Tank Truck Carriers (NTTC), C & R Fleet Services, and WRD, Inc.) requested that PHMSA make the consensus standards referenced in the ANPRM available to the public electronically. The commenters cited costs to purchase and review the copyrighted documents as barriers to informed public comment on issues presented in the ANPRM. PHMSA agrees. PHMSA understands the costs of purchasing copyrighted consensus standards can create an unnecessary burden on interested parties and potentially limit public participation in the rulemaking process. This was not PHMSA's intent.

                    In response to commenter requests, PHMSA has obtained permission from ASME to post an electronic version of the 2010 edition of the ASME                     *Boiler and Pressure Vessel Code, Section XII*                     (ASME Section XII) on PHMSA's website. The electronic version of ASME Section XII will be available for the duration of the comment period (through May 23, 2011) at the following URL:                     *http://phmsa.dot.gov/​hazmat.*                     Further, in response to commenter requests, the National Board has voluntarily posted copies of the relevant                           ( print page 11192)                        sections (NBIC Part 2, Section 6, Supplement 6, “Continued Service and Inspection of DOT Transport Tanks,” and NBIC Part 3, Section 6, Supplement 6, “Repair, Alteration, and Modification of DOT Transport Tanks”) of the 2007 edition of the                     *National Board Inspection Code*                     for public review at                     *www.nationalboard.org*. Both documents are available electronically for review and comment, free of charge. However, PHMSA reminds the public that the documents are copyrighted and any reproduction of the documents without the permission of ASME or the National Board is prohibited.                

## III. Comment Period Extension

Several commenters to the December 23, 2011 ANPRM request a comment period extension (NTTC, C & R Fleet Services, Compressed Gas Association, and WRD, Inc.). Commenters cite difficulties in obtaining and reviewing copies of the referenced consensus standards, technical nature of the subject matter, and a wide range of potential burdens as reasons PHMSA should provide commenters with additional time to review the consensus standards and generate informed comment submissions to the docket. PHMSA agrees. Therefore, the comment period for the December 23, 2010 ANPRM is extended from March 23, 2011 until May 23, 2011.

## IV. Conclusion

PHMSA believes the electronic availability of the referenced consensus standards and the extension of the comment period will provide commenters with sufficient time to review the consensus standards and generate informed comments on the December 23, 2010 ANPRM.

Issued in Washington, DC, on February 22, 2011 under authority delegated in 49 CFR part 106.
