SUPPLEMENTARY INFORMATION: Section 933 of the FAA Reauthorization Act 
of 2024, titled ``Special Authority for Transport of Hazardous 
Materials by Commercial Package Delivery Unmanned Aircraft Systems,'' 
directs the Secretary of Transportation to use a risk-based approach to 
establish the operational requirements, standards, or special permits 
necessary to approve or authorize an air carrier to transport hazardous 
materials by UAS providing common carriage under Title 14 of the Code 
of Federal Regulations (14 CFR) part 135, or under successor 
authorities, as applicable, based on the weight, amount, and type of 
hazardous material being transported and the characteristics of the 
operations subject to such requirements, standards, or special purposes 
(see subsection (a)). The FAA and PHMSA addressed subsection (e)(1) of 
the FAA Reauthorization Act of 2024 by hosting a joint public meeting 
on August 22, 2024.\1\

---------------------------------------------------------------------------

    In addressing the statutory requirement, the FAA and PHMSA are 
providing guidance that will enable operators to account methodically 
for what can be unique risks associated with the transportation of 
hazardous materials by UAS. This guidance is intended for 14 CFR part 
135 UAS applicants and certificate holders who seek authorization to 
transport hazardous materials, including those certificate holders 
seeking to expand the scope of their current hazardous materials 
programs. The document is available at: https://www.faa.gov/hazmat/air_carriers/operations/drones.
