Final rule; extension of compliance dates and corrections.
This document extends the compliance dates and makes minor corrections for certain requirements adopted in a final rule published under Docket No. RSPA-01-10373 (HM-220D) on August 8, 2002 (67 FR 51626), which amended requirements applicable to the maintenance, requalification, repair, and use of DOT specification cylinders. RSPA is taking action in response to appeals stating that the October 1, 2002 effective date is unreasonable. This action provides additional time, until May 30, 2003, for RSPA to fully evaluate and determine the merits of issues raised by appellants concerning these requirements and their requests for clarification of certain other Start Printed Page 61288requirements. These appeals will be fully addressed in a later document. Because these amendments do not impose new requirements, notice and public comment are unnecessary.
Effective Date: This rule is effective on October 1, 2002.
Compliance Date: However, certain regulatory actions will not occur until the date specified in the regulatory text.Start Further Info

On August 8, 2002, the Research and Special Programs Administration (RSPA, we) published a final rule under Docket No. 01-10373 (HM-220D) (67 FR 51625) amending the requirements of the Hazardous Materials Regulations applicable to the maintenance, requalification, repair, and use of DOT specification cylinders. The August 8, 2002 final rule, amended the HMR to:
(1) Prohibit a filled cylinder with a specified service life from being offered for transportation in commerce after its service life has expired.
(2) Remove authorization for the manufacture of DOT specification cylinders using aluminum alloy 6351-T6. Cylinders manufactured with this aluminum alloy have a greater risk of failure than other aluminum cylinders.
(3) Incorporate by reference new and updated Compressed Gas Association (CGA) standards and updated American Society for Testing and Materials (ASTM) standards.
(4) Require each person who performs a requalification function that requires marking of an inspection or retest date on a cylinder to have approval from the Associate Administrator for Hazardous Materials Safety (Associate Administrator).
(5) Standardize requirements for repair and rebuilding of DOT-4 series cylinders, other than the DOT 4L.
(6) Allow the application of requalification markings on cylinders by using alternative methods that produce durable, legible marks.
(7) Require pressure relief devices on all DOT-3 series specification cylinders to be set at test pressure with a tolerance of −10% to +0 beginning at the first requalification due on or after the effective date of this final rule.
In addition, we consolidated requirements for obtaining approval to be a cylinder requalifier, or an independent inspection agency, or to have chemical tests or analyses performed outside the United States on cylinders manufactured outside the United States in a new Subpart I in Part 107.
We received approximately 20 appeals of the implementation of HM-220D, either in total or in part. We received appeals from representatives of industrial gas trade associations, gas distributors, shippers, carriers, cylinder manufacturers and requalifiers.
Extension of Compliance Date
Most appellants request that we extend the October 1, 2002 effective date for certain requirements adopted in the final rule. They state a 60-day implementation period is unreasonable for certain requirements. They request that we delay implementation of the particular requirements until we have had an opportunity to further review and address their specific concerns. We agree that the October 1 effective date of certain provisions should be extended. Therefore, in this final rule, we are providing a May 30, 2003 compliance date for the following requirements:
—Sections 173.40(b) and 173.301a(d)(3)—Requiring the pressure at 55 °C (131 °F) in a cylinder not to exceed the service pressure of the cylinder. This provision affects Hazard Zone B gases, such as hydrogen sulfide.
—Sections 173.301(f)(2) and 177.840(a)(1)—Requiring the inlet port to the relief channel of the pressure relief device, when installed, must be in the cylinder's vapor space.
—Section 173.301(f)(3)—Requiring the set pressure of the pressure relief device to be at test pressure with a tolerance of −10% to +0 for DOT 3-series cylinders.
—Section 173.301(h)(2)—Allowing cylinders filled with a flammable, corrosive, or noxious gas to have the valves protected by loading the cylinders in an upright position and securely bracing in cars or motor vehicles, when loaded by the consignor and unloaded by the consignee.
Editorial Corrections and Clarifications
Appellants expressed concern about a requirement in the August 8, 2002 final rule that prohibits a welded cylinder from being used for Hazard Zone A materials (see §§ 173.226(a) and 173.228(b) of the August 8, 2002 final rule). Appellants ask us to provide time for transporting filled cylinders for reprocessing or disposal of the cylinder's contents. We agree. In this final rule, we are revising the prohibition to permit a welded cylinder that is filled with a Hazard Zone A material prior to October 1, 2002, to be transported for reprocessing or disposal until April 1, 2003.
In addition, in this final rule, we are clarifying a requirement applicable to cylinders used to transport oxygen. In § 173.302, the August 8, 2002 final rule included provisions applicable to aluminum cylinders used to transport oxygen. One of the requirements states that each valve or portion of a valve that comes into contact with the oxygen being transported must be constructed of brass or stainless steel. Several appellants point out that some aluminum oxygen cylinders have valve components made of non-metallic materials that may come in contact with the oxygen. It was not our intention to require persons transporting oxygen in aluminum cylinders to replace non-metallic valves or valve components with brass or stainless steel. Therefore, in this final rule we are clarifying that metallic portions of valves that may come into contact with the oxygen in the cylinder must be constructed of brass or stainless steel.
Appellants also point out that we inadvertently excepted all acetylene cylinders from the valve protection requirements in § 173.301(h) of the August 8, 2002 final rule. Appellants are correct that this was not our intent. As we stated in the preamble to the final rule (67 FR 51631), our intention was to except only acetylene MC cylinders and other types of small-capacity cylinders from the valve protection requirements. Therefore, in this final rule, we are revising the exception for acetylene cylinders to except small capacity MC and B style cylinders from valve protection requirements.
Partial Denial of Appeals
CGA and several other appellants also contend that HM-220D was issued as a final rule with no opportunity for public comment. They state that HM-220D should be withdrawn and converted to an NPRM with sufficient time provided for persons to review and comment on the proposals. We do not agree. We proposed to make the changes adopted under HM-220D in a notice of proposed rulemaking published under Docket No. RSPA-98-3684 (HM-220) on October 30, 1998 (63 FR 58460). The comment period for HM-220 closed September 30, 1999. In addition, we held three public meetings to discuss the HM-220 proposals on December 8, 1998 (63 FR 58460; October 30, 1998), January 28, 1999 (63 FR 72224; December 31, 1998), and April 13-15, 1999 (64 FR 9114; February 24, 1999). On February 13, 2002, we separated the proposals applicable to current DOT specification Start Printed Page 61289cylinders, from those applicable to the metric-marked cylinders, and placed them under Docket No. RSPA-01-10373 (HM-220D) (67 FR 6667). Therefore, RSPA finds the appellants' claim that we did not provide the public with an opportunity to comment on this rule is without merit and is denied.
RSPA's procedural regulations for handling appeals of final rules require us to take action on appeals within 90 days after the date of publication of the final rule (see 49 CFR 106.130). If we anticipate that our decision on an appeal may be delayed beyond the 90-day time frame, we must provide notice of the delay in the Federal Register. For the August 8, 2002 final rule, the 90-day deadline is November 6, 2002. We intend to consider the issues raised by appellants concerning the above listed sections of the August 8, 2002 final rule as expeditiously as possible; however, it is unlikely that we will be able to resolve all the issues by November 6, 2002. We plan to address all issues raised by appellants by May 30, 2003.Start List of Subjects
