k. Description of Project: The proposed project would consist of a dam (height is undetermined) located within the Boulder Creek Canyon immediately upstream
of its confluence with the Chickaloon River. The dam would impound Boulder Creek to a maximum elevation of 1,555 feet, forming
a reservoir with a maximum surface area of 270 acres. The proposed dam would be built and operated as a storage-based generation
facility and create impoundment capacity suitable for capturing and storing large runoff events in the summer and fall. This
would provide stable baseload generation during winter months when precipitation occurs as snow and natural inflows are minimal.
An 8-foot diameter concrete lined horseshoe tunnel would extend approximately 8,000 feet from the dam downhill before transitioning
to a smaller 5-foot diameter steel penstock for approximately 1,000 feet to the proposed powerhouse. The tunnel and penstock
would convey flow through an elevation drop of approximately 440 feet to the powerhouse site located along the Chickaloon
River at an elevation of approximately 980 feet. The powerhouse would contain two Francis-type turbine-generator units with
a rated capacity of 4.2 megawatts (MW) each for a total powerhouse capacity of 8.5 MW. The potential annual energy generation
would be 29 gigawatt-hours (GWh).

  Adjacent to the powerhouse would be a substation with a new high voltage transmission line spanning approximately 4,300 feet
  to an existing transmission line corridor along the Glenn Highway.

When a Declaration of Intention is filed with the Federal Energy Regulatory Commission, the Federal Power Act requires the
Commission to investigate and determine if the project would affect the interests of interstate or foreign commerce. The Commission
also determines whether or not the project: (1) would be located on a navigable waterway; (2) would occupy public lands or
reservations of the United States; (3) would utilize surplus water or water power from a government dam; or (4) would be located
on a non-navigable stream over which Congress has Commerce Clause jurisdiction and would be constructed or enlarged after
1935.
