          - [Project No. 14857-000]

On September 11, 2017, Watterra Energy, LLC (Watterra Energy) filed a preliminary permit application pursuant to section 4(f) of the Federal Power Act proposing to study the feasibility of the proposed Saylorville Dam Hydroelectric Project No. 14857-000, to be located at the existing Saylorville Dam on the Des Moines River, near the City of Des Moines in Polk County, Iowa. Saylorville Dam is owned by the United States government and operated by the United States Army Corps of Engineers.

The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owner's express permission.

Watterra Energy's proposed project would consist of: (1) A new 20-foot-diameter steel penstock that would be inserted into an existing 22-foot-diameter by 640-foot-long concrete conduit; (2) a new 55-foot-wide by 70-foot-long by 30-foot-high concrete powerhouse; (3) three new 5.22-megawatt (MW) turbines, with a combined generating capacity of 15.66 MW; (4) a new 70-foot-long by 55-foot-wide substation; (5) a new 7,000-foot-long, 13.8-kilovolt transmission line; and (6) appurtenant facilities. The project would have an estimated annual generation of 58 gigawatt-hours.
