EXHIBIT 1

DESCRIPTION OF PROPOSED PROJECT

1. Description of Existing Structures

The Flood Control Acts of 1944 and 1946 approved the construction of the Clark Canyon dam as part of the Reclamations Pick-Sloan Missouri River Basin Program, East Bench Unit. The approximately 2,950-foot-long zoned, earth-fill dam includes a concrete intake structure and conduit in the reservoir, a shaft house at the crest of the dam, a 9-foot-diameter conduit that discharges water to a concrete stilling basin, a gate chamber with four high pressure gates, two of which act as emergency gates, and an uncontrolled concrete spillway.

2. Description of Proposed Project Features

Steel Liner – Clark Canyon Hydro proposes to install a new 8-foot-diameter steel penstock within the existing concrete conduit. The penstock will extend approximately 360 feet from the existing gate chamber to near the existing outlet works stilling basin. A trifurcation will then separate the flows into two steel penstocks (Powerhouse Penstocks) and one steel penstock, each of which will discharge into the existing outlet works stilling basin.

Powerhouse Penstocks – Two steel 8-foot-diameter, 35-foot-long penstocks (the length includes the reducing sections) will convey flows from the trifurcation to the proposed powerhouse.

20150421-5044 FERC PDF (Unofficial) 4/20/2015 5:32:03 PM

Directly upstream of the powerhouse, each of the two 8-foot-diameter penstocks will transition to a 6-foot diameter-steel penstock before entering the powerhouse. These penstocks will direct flows to both of the new turbines.

Outlet Stilling Basin Discharge – The 8-foot-diameter steel penstock leaving the trifurcation to the outlet stilling basin will be approximately 10 feet long. A 7-foot-diameter fixed cone valve with a reducer will be installed at the end of the 8 foot diameter steel penstock for controlled discharge into the existing outlet works stilling basin.

Powerhouse – The dimensions of the powerhouse will be approximately 41 feet by 62.5 feet. The powerhouse will contain two vertical Francis-type turbine/generator units with a combined generating capacity of 4.7 MW, and a combined discharge capacity of 700 cfs. The powerhouse will be a reinforced concrete substructure. Removable roof hatches will be provided for access to the equipment for maintenance. A crane will be provided for normal maintenance activities; however, a mobile crane will need to be brought to the site for installation and removal of the turbine/generator equipment. Controls, switchgear, and other electro-mechanical equipment will be located inside the powerhouse building. The powerhouse will include a control room.

Draft Tubes and Tailrace – Water discharged from the turbines will pass through integral steel draft tubes (approximately 25 feet long, within the powerhouse). Each draft tube will transition into a concrete draft tube/tailrace section with integrated stop log channels outside the powerhouse, channels approximately 15-foot-wide by 17-foot-long and will discharge into the existing spillway stilling basin. Draft tubes outlets inside the tailrace will be configured with stop log slots for removable bulkheads to allow for dewatering.

Powerhouse Substation – The powerhouse substation will be located northeast of the powerhouse (approximately 1,100 feet downstream of the powerhouse). The substation includes a 4.16 kV to 69 kV step-up transformer with switchgear on concrete pad foundations with containment and a grounding grid. Underground transmission line will be between the powerhouse and the powerhouse substation.

Transmission –The new transmission line will run from the powerhouse substation approximately 7.9 miles to the Peterson Flat substation and will be adjacent to and within sections of the Highway 324 right-of-way (ROW) as shown in the attached map. The new line will consist of a single pole at a voltage of 69kV with an average span distance of 428 feet, and 13 poles per mile on a proposed 80 foot corridor. The proposed transmission line will cross Bureau of Reclamation (BOR), Montana State Land and run adjacent to private lands within the Beaverhead County Highway 324 Right of Way (ROW).

3. Existing Reservoir

No proposed dams or reservoirs are included in the project. The existing Clark Canyon dam is federally owned. The reservoir has a capacity of 253,442 acre-feet and an active capacity of 126,117 acre-feet. The water surface area of the reservoir is 4,935 acres.

4. Transmission Line

A new transmission line will run from the powerhouse substation approximately 7.9 miles to the Peterson Flat substation and will be adjacent to and within sections of the Highway 324 right-of- way (ROW) as shown in the attached map. The new line will consist of a single pole at a voltage of 69 kV with an average span distance of 428 feet, and 13 poles per mile on a proposed 80 foot corridor. The proposed transmission line will cross Bureau of Reclamation and Montana State lands within the Beaverhead County Highway 324 ROW.

5. Proposed Generation and Facilities

The Project will have an installed generating capacity of 4.7 MW with two 2.35 MW Francis type units (turbine and generator). At the selected size, the project will use flows ranging from 87.5 cfs to 700 cfs (87.5 cfs to 350 cfs per unit), and will have a maximum static head of 110 feet and an average static head of 87 feet. On average, the project will generate approximately 15.4 GWh per year.

6. Project Lands

The project is located on federal lands managed by the Bureau of Reclamation. FERC Form 587 is attached to this application as part of Exhibit 3.

7. Public Interest

The public interest will be served by the development of a source of non-polluting renewable energy at an existing dam without changing the authorized flow regime of the river.

STUDY PLAN

1. Completed Studies

Clark Canyon Hydro received an original license to construct a substantially similar hydroelectric project on August 26, 2009 (Project No. 12429).

Clark Canyon Hydro has already completed aquatic/fish, water quality, terrestrial, cultural, visual, transmission/interconnection, and other studies as part of the licensing effort. A brief summary of these previous efforts is listed below:

Cultural Resources The Nez Perce, Northern Arapaho, Shoshone-Bannock Tribes, Eastern Shoshone Tribe, and the Confederated Salish and Kootenai Tribes were invited to consult in the licensing process on May 22, 2006. A cultural resource inventory was prepared on September 13, 2006. A cultural resource inventory report was distributed to the tribes and the Montana SHPO on June 13, 2008.

Terrestrial Resources A proposed Vegetation Survey Plan was provided to the agencies for comment on March 9, 2007. After agency correspondence and survey efforts were completed, the final botanical survey report was filed with the Commission on October 8, 2007. The final botanical survey report included vegetation characterization and survey of sensitive plants, weed management plan, and revegetation guidelines.

Visual Resources Clark Canyon Hydro prepared and submitted for agency review a visual resources management plan in September 2007 with a final plan submitted November 5, 2007. On September 19, 2008, Clark Canyon Hydro filed the Final Visual Resources Management Plan with the Commission and Stakeholders.

Recreation Clark Canyon Hydro filed recreation resources information with Montana Department of Fish, Wildlife, and Parks; the National Park Service; and East Bench Irrigation District on February 6, 2008. Additional interstate highway access information was provided to Montana Department of Fish, Wildlife, and Parks; Montana Department of Transportation; Federal Highway Administration and East Bench Irrigation District on February 6, 2008. On March 5, 2008 Clark Canyon Hydro filed with the Commission and Stakeholders additional information including defining public access/recreational facilities within proposed project area in response to the Commission's December 7, 2007 letter. The Buffalo Bridge Fishing Access Road Management Plan was submitted to the Commission on July 18, 2011. The Interpretive Sign Plan was submitted to the agencies on October 14, 2010 and to the Commission on December 10, 2010.

20150421-5044 FERC PDF (Unofficial) 4/20/2015 5:32:03 PM

Aquatic/Fish Resources An Instream Flow Release Plan was filed on August 15, 2008, for Stakeholder comments and a final plan was filed with the Commission October 7, 2008. A Water Quality and Fisheries Protection Plan was filed for Stakeholder comments on August 15, 2008. The Riparian Habitat Protection Plan was submitted for agency comment on August 1, 2008 and then the final plan was completed in September 2008. On September 25, 2008 Clark Canyon Hydro filed with the Commission and Stakeholders a Water Quality and Fisheries Protection Plan. Water Quality Monitoring Reports for data collected during 2009 was filed with the Commission and Stakeholders on May 13, 2010 The Construction Water Quality Monitoring plan was provide to the Commission and Stakeholders on February 3, 2011. In 2014, Clark Canyon Hydro completed an aeration assessment/modeling effort for the proposed aeration equipment for the project and other equipment options.

Engineering Plans and Specifications From 2010 through 2014, Clark Canyon Hydro has engaged the Bureau of Reclamation to review the engineering design and prepare for construction under Memorandum of Understanding #R10MU60019. This process has included meetings, field exploration, dam safety risk analysis, dam excavation design, design review & approval and preparation for the Construction Operation and Maintenance Contract. On August 22, 2013, and June 4, 2014, Clark Canyon Hydro submitted updated engineering drawings, specifications and design reports to the Commission.

2. Proposed Studies

Based on its prior agency consultation, Clark Canyon Hydro does not believe that further resource studies are required to prepare a license application for the Clark Canyon Hydroelectric Project. Appropriate state and federal agencies and other stakeholder will have the opportunity to review the completed studies, and consult and comment on the proposed project.

3. New Roads At this time no additional roads are planned for the study phase of the Project. 4. Work Plan for New Dam Construction

The project does not include plans for any new dam construction.

5. Statement of Cost and Financing The cost to complete the proposed studies and licensing process during the requested three-year period is estimated at less than $250,000 because many studies have already been completed at a cost greater than $1.5 million. It is anticipated that these costs will be funded by Clark Canyon Hydro, LLC.
