888 First Street NE, Room 1A, Washington, DC 20426. Submissions sent
via any other carrier must be addressed to: Debbie-Anne A. Reese,

The Commission's Rules of Practice and Procedure require all

list for the project. Further, if an intervenor files comments or
documents with the Commission relating to the merits of an issue that

l. Description of Request: The applicant requests approval to
replace the Thompson Falls Project's older Unit 6 Allis Chalmers
Vertical Francis turbine with a new and more efficient American Hydro
Vertical Francis turbine. The proposed scope of work for Unit 6
includes complete turbine replacement and generator stator rewind. The
applicant expects the turbine replacement to result in an increase of
1.91 megawatts (MW) to the total installed capacity of the unit,
increasing the project's authorized installed capacity from 92.37 MW to
94.28 MW. The applicant states that the hydraulic capacity would
increase from 23,252 cubic feet-per-second (cfs) to 23,350 cfs. The
applicant states the hydraulic throughput change that would result from
the new turbine is de minimis and would not cause any change in the
operation of the units or have quantifiable environmental effects.
