`By letter dated September 11, 2023, you submitted design documents for the High Falls,

`Project for the following proposed construction:
`
`Installation of access stairs at Saranac River near the High Falls Development.
`•
`• Regrading in front of the powerhouse main door and construction of sidewalk
`slab, and regrading of vehicle parking area and construction of concrete slab at
`the Kents Falls Development.
`• Access road improvements and construction of new concrete slab within vehicle
`access area and debris stockpiling area at the right abutment of the Cadyville

`
`
`
`
`
`Our review of the design drawings find that the proposed work would not affect the safety
`of the project structure, or the adequacy of the project works to perform their intended
`functions.
`
`You are reminded to obtain permits and concurrence for the proposed construction from
`all necessary state and federal resource agencies. Any drawdown of the headpond levels or
`modifications of the operation modes should be coordinated with the agencies to address
`any potential environmental concerns. Please note that if any changes are made that result
`in the modification of project operations, it is also your responsibility to coordinate these
`changes with FERC.
`
`Your cooperation and continued interest in dam safety are appreciated. If you have any
`questions, please contact Mr. Eyob at (212) 273-5929 or email at mussie.eyob@ferc,gov.
`
`Sincerely,
`
`
