Administrator to do so. Accordingly, PHMSA did not propose adopting this provision in
the August 15, 2012, NPRM. During the comment period, PHMSA was alerted that

cylinders. While this petition has merit, we did not receive it in time to address in this
rulemaking. We will consider this petition in a future rulemaking.
Additional Clarification on the Requirements for Lithium Batteries:
On August 15, 2012, PHMSA published an NPRM associated with this rulemaking

regarding the requirements for the air transportation and handling of lithium batteries.
However, in that NPRM, PHMSA did propose the incorporation by reference of the 2013-
2014 Edition of the ICAO Technical Instructions which covers the air transportation of
