Department of Transportation July 31, 2008 – Federal Register Recent Federal Regulation Documents

PHMSA's Office of Pipeline Safety (OPS) is requesting each operator of a rural low-stress hazardous liquid pipeline to complete a voluntary survey to gather information concerning the mileage and characteristics of these pipelines to assess the costs of subjecting rural low-stress pipeline mileage to the pipeline safety standards and regulations pursuant to the PIPES Act. The purpose of this notice is to request all operators of LSPs to complete the voluntary survey, including operators of low-stress pipelines that will not be subject to the pipeline safety standards and regulations until Phase II of the rulemaking proceeding.

The FAA is superseding an existing airworthiness directive (AD) for RRD Dart 528, 529, 532, 535, 542, and 552 Series turboprop engines. That AD currently requires a dimensional inspection of the intermediate pressure turbine (IPT) disk or an ultrasonic inspection of the seal arm contact between the high pressure turbine (HPT) and the IPT disk seal arm and reworking or replacing the IPT disk if worn beyond acceptable limits. This AD continues to require those actions. This AD results from us including an incorrect engine model and omitting an engine model from the applicability of the existing AD. We are issuing this AD to prevent HPT disk failure, which can result in an uncontained engine failure and damage to the airplane.

PHMSA proposes to amend the Hazardous Materials Regulations to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. These revisions are necessary to harmonize the Hazardous Materials Regulations with recent changes to the International Maritime Dangerous Goods Code, the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air, and the United Nations Recommendations on the Transport of Dangerous Goods. The proposals include amendments and clarifications addressing the safe transportation of batteries and battery-powered devices. Consistent with recent changes to the International Civil Aviation Organization's Technical Instructions, PHMSA is proposing to clarify the prohibition against transporting electrical devices, including batteries and battery-powered devices that are likely to create sparks or generate a dangerous amount of heat. PHMSA also is proposing to modify and enhance requirements for the packaging and handling of batteries and battery-powered devices, particularly in air commerce, to emphasize the safety precautions that are necessary to prevent incidents during transportation. PHMSA developed these proposals in conjunction with the Federal Aviation Administration in order to enhance the safe transportation of batteries and battery-powered devices.
