Operations of these additional UAS will be in full compliance with the terms of Exemption Nos. 11735 and 

11735A, and in accordance with the procedures set forth in the relevant pilot operating handbooks for each 

UAS. 

Trihydro refers the FAA to its original Petition for Exemption dated March 26, 2015 (Docket No. FAA20 15-0854) for a listing of the regulations for which an exemption is being sought, a demonstration of the 

public interest, and a showing of an equivalent level of safety. There have been no changes in the conditions 

and reasons relative to public interest and safety that were the basis for granting the original Exemption. 

Trihydro respectfully suggests that good cause exists for not publishing a summary of this petition for 

amendment in the Federal Register because the requested amendment would not set a precedent. 

If you have any questions or need additional information to process this petition for amendment, please 

contact me at (307) 745-7474, or by email at dforry@trihydro.com. 

Sincerely, 

Trihydro Corporation
