Analyzed Economic Effects
4 provisions identified: 3 benefits, 0 costs, 1 mixed.
Cylinder Service Life Extended Past 15 Years
If your company ships hazardous gases, one applicant asks to let certain cylinders stay in service beyond 15 years. The request covers transport by motor vehicle, rail freight, cargo vessel, and cargo aircraft (modes 1, 2, 3, 4).
Authorize Lithium-Ion Packs and Propulsion Tank
One applicant seeks permission to transport a single-tank propulsion system, lithium‑ion battery packs, and to move them from additional locations by motor vehicle (mode 1). This change would directly affect companies that handle or ship those propulsion systems and lithium‑ion battery packs.
Alternative Requalification Testing Allowed
An applicant requests a modification to allow alternative requalification testing for cylinders and to remove the requirement that the special permit grantee also be the owner of the cylinders. The modification applies for motor vehicle and cargo vessel transport (modes 1 and 3).
Boeing Added as Approved Carrier
An applicant proposes modifying a special permit to add The Boeing Company as an approved carrier for the permit, for motor vehicle transport (mode 1). This change affects who is authorized to carry the materials covered by that special permit.
