Hazardous Materials: Chemical Oxygen Generators

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA).

ACTION: Final rule; confirmation of effective date.

SUMMARY: PHMSA is confirming the effective date of its direct final rule, published under Docket No. PHMSA-2009-0238 (HM-224G) on October 15, 2009, to amend the Hazardous Materials Regulations by revising the quantity limitation from 25 kg ``gross'' to 25 kg ``net'' for packages of chemical oxygen generators transported aboard cargo aircraft only.

The direct final rule stated that it would become effective on November 16, 2009 unless an adverse comment or notice of intent to file an adverse comment was received by November 16, 2009. PHMSA did not receive any adverse comments or notice of intent to file an adverse comment to its October 15, 2009 direct final rule.

SUPPLEMENTARY INFORMATION:

On January 31, 2007, PHMSA issued a final rule under Docket No.

RSPA-04-17664 (HM-224B) to enhance the safety standards for transportation by air of compressed oxygen, other oxidizing gases, and chemical oxygen generators (72 FR 4442). Specifically, the final rule amended the HMR to require cylinders of compressed oxygen and chemical oxygen generators to be transported in an outer packaging that: (1)

Meets the same flame penetration resistance standards as required for cargo compartment sidewalls and ceiling panels in transport category airplanes; and (2) provides certain thermal protection capabilities so as to retain its contents during an otherwise controllable cargo compartment fire.

In response to a petition, PHMSA determined it was necessary to revise the quantity limitation for packages of chemical oxygen generators transported aboard cargo aircraft only from 25 kilograms

``gross'' to 25 kilograms ``net,'' and published a direct final rule in the Federal Register on October 15, 2009.

PHMSA stated in the direct final rule that it would consider as adverse comments only those comments that explain why a rule would be inappropriate, or would be ineffective or unacceptable without a change. PHMSA did not receive an adverse comment or notice of intent to file an adverse comment in response to the direct final rule. In this present notice, PHMSA is confirming that the effective date for the

October 15, 2009 direct final rule is November 16, 2009.
