Hazardous Materials Packaging-Composite Cylinder Standards; Public Meeting

Notice of public meeting.

This notice is to advise interested persons that PHMSA will conduct a public meeting to provide further clarification regarding PHMSA's intent to modify certain special permits in accordance with 49 CFR 107.121. These special permits authorize the manufacture, marking, sale and use of non-DOT specification composite cylinders. The non-DOT specification cylinders authorized by PHMSA's special permits conform to the basic requirements for fiber reinforced plastic (DOT-FRP) or fully wrapped carbon-fiber reinforced aluminum lined cylinders (DOT- CFFC) standards. PHMSA believes that these special permits should be modified to reflect the appropriate International Standards Organization (ISO) standards for composite cylinders ISO 11119 Parts - 1, -2, -3 incorporated by reference into the Hazardous Materials Regulations (HMR).
