FERC Issues Order Amending License re Copper Valley Electric Association, Inc Under P-13124
(Targeted News Service Via Acquire Media NewsEdge) WASHINGTON, June 20 -- The U.S. Department of Energy's Federal Energy Regulatory Commission issued the text of the following delegated order: Copper Valley Electric Association, Inc.
Project No. 13124-015 ORDER AMENDING LICENSE (Issued June 20, 2014) 1. On April 14, 2014, Copper Valley Electric Association, Inc., licensee for the Allison Creek Project No. 13124, filed an application to modify the design of the project powerhouse, tailrace, and transmission line. Theproject is located on Allison Creek in Valdez, Alaska and does not occupy federal lands.
Background 2. The Commission issued an original license for the Allison Creek Project on August 1, 2013. The unconstructedproject, as amended, consists of: (a) a 16-foot-high, 130-foot-long diversion dam including a 50-foot-long overflow spillway section located 10,000 feet (about 1.9 miles) upstream of the mouth of Allison Creek and 2,350 feet downstream from the outlet of Allison Lake; (b) a screened intake in the spillway section; (c) a 42 to 36-inch-diameter, 6,900-foot-long buried steel penstock including a 700-foot-long tunnel section; (d) an approximately 4,000-foot-long temporary construction access road; (e) a 65-foot-wide, 65-foot-long, 48-foot-high powerhouse containing two horizontal Pelton turbine/generator units with a total installed capacity of 6.5 megawatts (MW); (f) a 120-foot-long tailrace extending from the west side of the powerhouse to Allison Creek via a concrete channel and the existing creek bed; (g) a 550-foot-long, 24-foot-wide permanent access road to the powerhouse; (h) a parking area; (i) a transformer located in a switchyard adjacent to the parking area; (j) a 3.8-mile-long, 34.5 kilovolt (kV) transmission line connecting to an existing substation; and (k) appurtenant facilities.
Proposed Amendment 3. The licensee states that following a reevaluation of its redundancy needs and construction costs, it has determined a single unit would provide satisfactory servicewhile improving project economics. Therefore,the licensee now proposes to install a single 6.5-MW Pelton turbine/generator unit. The unit would have a maximum hydraulic capacity of 80 cubic feet per second, identical to the combined maximum hydraulic capacity of the two units originally envisioned. The change in the number of units would allow the licensee to decrease the size of the powerhouse, reducing itto a structure 65 feet long, 55 feet wide, and 48 feet high. The licensee also proposes to construct the tailrace on the north side of the powerhouse, rather than the west side, reducing its length from 120 feet to 70.5 feet. The proposed tailrace would continue to return flow to Allison Creek upstream of a natural anadromous fish passage barrier.
4. The licensee also proposes to modify the voltage and route of the project transmission line. The line would continue to be 3.8 miles long; however, it would be energized to 25 kV and would follow a utility easement along a section boundary to the south of the original route. The line would interconnect at the same location as previously proposed. The revised route would generally be located on land owned by the State of Alaska but an approximately 400 foot long section would occupy land owned by a pipeline partnership.
Pre-Filing Consultation 5. Prior to filing its application with the Commission, the licensee consulted with the Alaska State Historic Preservation Officer (Alaska SHPO), the National Marine Fisheries Service (NMFS) and the Alaska Department of Fish and Game (Alaska DFG). The licensee provided a copy of its proposal to the U.S. Fish and Wildlife Service, but the agency informed the licensee that it lacked sufficient resources to evaluate the proposal, and therefore, did not object to the amendment.On May 8, 2013, the SHPO concurred that no historic properties would be affected. On April 3, 2014, NMFS replied by email and stated that the proposed license amendment does not pose any risk to salmon or other aquatic resources. The NMFS also pointed out that the new transmission line route reduces the possibility of some sensitive wetland impacts. The NMFS had no objections to the proposed amendment.
6. Alaska DFG commented in its email dated April 3, 2014, that it had no objection to the amendment and specifically stated it had no concerns with the new alignment of the transmission line or with the change in the footprint and location of the powerhouse. However, the Alaska DFG requested the single generator powerhouse be designed with a generator water bypass system to instantaneously maintain flow in the downstream reach in the event of a project shutdown. This would allow for bypass reach ramping and reduce effects on fish in the downstream reach, if the penstock must also be dewatered.
Public Notice 7. On May 1, 2014, the Commission issued a public notice that the amendment application was accepted for filing and soliciting comments, motions to intervene, and protests. On May 29, 2014, the U.S. Department of the Interior (Interior) filed comments pursuant to the public notice. In its letter, Interior expressed concerns about the licensee's lack of analysis in support of its license amendment application with regard to potential recreation and aesthetic impacts associated with the new routing of the transmission line. Because the new route is a significant change from the route analyzed in the June 21, 2013 environmental assessment (EA) prepared by Commission staff while reviewing the license application for the project, Interior recommends that the Commission scope, study, and analyze potential effects related to the proposed route. Interior also recommends that the licensee subsequently revise its April 14, 2014 application for amendment of license to consider these potential effects. Interior also stated in its letter that it had no comments on the proposed changes to the powerhouse and the tailrace.
8. In a letter dated June 3, 2014, the licensee responded to Interior's comments on the revised transmission line route and provided an expanded explanation of the aesthetic and recreational effects of the proposed route.
Administrative Conditions A. Project Description 9. The licensee submitted, with its April 14, 2014 amendment application, a revised Exhibit A that describes the modification to the design of the powerhouse, tailrace, and transmission line. The licensee's revised Exhibit A conforms to the Commission's regulations and is approved in ordering paragraph (C), superseding the existing Exhibit A.
B. Exhibit Drawings 10. The licensee filed four revised Exhibit F drawings and five revised Exhibit G drawings with its application. We have reviewed the drawings and found that they conform to the Commission's rules and regulations and are approved in this order. Ordering paragraph (D) approves the nine drawings and the licensee is required to file them in electronic format as shown in ordering paragraph (E).
C. Construction Related Articles 11. The obligations set forth under the license articles, including the requirements that the licensee file plans and specifications with the Commission's Division of Dam Safety and Inspections (D2SI) - Portland Regional Engineer, are applicable to this amendment. The licensee may not begin construction until the D2SI - Portland Regional Engineer has reviewed and commented on the plans and specifications, determined that all preconstruction requirements have been satisfied, and authorizes start of construction.
Environmental Analysis 12. Concurrent with this order, Commission staff is issuing a supplemental EA to analyze the environmental impacts of the licensee's amendment request which relies, in part, on the EA that was issued by Commission staff on November 20, 2013 to support a previous amendment request that was filed by the licensee on September 27, 2013. Only the environmental impacts of the changes to the powerhouse, tailrace, and transmission line were considered in the supplemental EA.
A. Powerhouse and Tailrace 13. The environmental impacts of the powerhouse would be essentially the same as those considered during the preparation of the June 21, 2013, EA to support the license. Construction would essentially occur in the same location but the footprint of the new powerhouse would be slightly smaller than the powerhouse originally licensed. The new tailrace would also be about 45.5 feet shorter than the currently licensed tailrace, but it would also be constructed with a higher grade.
14. In, its comments, Alaska DFG requested the single generator powerhouse be designed with a generator water bypass system to instantaneously maintain flow in the downstream reach in the event of a project shutdown. The Alaska DFG made a similar 10(j) request during licensing. In the license order, the Commission concluded that the constant delivery of minimum flows at the project's diversion, required by license Article 403, would provide a stable amount of flow to protect fishery resources downstream of the powerhouse. Therefore, an additional failsafe provision for the powerhouse was not needed. Since there are no changes in this amendment that would alter this determination, we have not incorporated this recommendation. The licensee is still required to comply with Article 403, which should provide adequate protection for downstream fisheries.
B. Transmission Line 15. The project would be located in a scenic, largely undeveloped area above the south shore of Port Valdez and at the base of the Chugach Mountains. The dramatic natural landscape provides an important scenic backdrop to the Valdez community, and is integral to the multiple recreation and tourism activities occurring in the region, such as boating, fishing, camping, and sightseeing. The project area is most visible from Port Valdez, the city of Valdez, a portion of the Richardson Highway (a designated scenic byway), and from the Solomon Gulch Trail.
16. We've reviewed Commission staff's original EA issued June 21, 2011, for this project and staff's EA issued November 20, 2013 for the licensee's previous amendment application. We've also reviewed the Recreation and Aesthetic Resources report that was included in Volume III of the original license application filed on August 25, 2011, Interior's comments and the licensee's response to those comments. We agree with the licensee that the proposed new transmission line would have similar aesthetic and recreation effects as the licensed line. From key viewpoints, the proposed new line would be difficult to see, similar to the licensed line, and routing the line away from a one-mile stretch of the Solomon Gulch trail could improve aesthetics. We disagree with Interior that additional scoping and studies are warranted for the licensee's proposed changes. We recommend approving the licensee's proposed new transmission line with existing mitigation measures already required by the license.
17. The environmental effects of construction and operation of the amended powerhouse and tailrace are not significantly different from those that were already considered and approved in the project license. In addition, the proposed transmission line route would not result in any significant changes in recreation or aesthetics from the route that was previously studied and licensed. Implementation of environmental measures already required by the project license would minimize or avoid identified impacts.
18. In our supplemental EA Commission staff determined that the approval of the proposed amendment to the Allison Creek Hydroelectric Project would not constitute a major federal action significantly affecting the quality of the human environment.
Conclusion 19. We have reviewed the licensee's application to amend its license in order to change the number of generating units, modify the design of the powerhouse and tailrace, and revise the transmission line route and voltage at the unconstructed project. We conclude that the licensee's proposal would help reduce the cost and difficulty of project construction while adequatelyprotecting wildlifeand aesthetic resources. Therefore, the amendment application will be approved, as considered herein.
