Washington, D.C. 20426 Re: Susitna-Watana Hydroelectric Project, Project No. 14241-000 Filing of Initial Study Plan Meetings Transcripts and Additional Information in Response to October 2014 Initial Study Plan Meetings Dear Secretary Bose: By letter dated January 28, 2014, the Federal Energy Regulatory Commission (Commission or FERC) modified the procedural schedule for the preparation and review of the Initial Study Report (ISR) for the proposed Susitna-Watana Hydroelectric Project, FERC Project No. 14241 (Project).1 As required by the Commission’s January 28 letter, the Alaska Energy Authority (AEA) filed the ISR with the Commission on June 3, 2014 and conducted ISR meetings on October 15, 16, 17, 21, 22, and 23, 2014. Attached as Attachments A-1 through F-2 are the written transcripts (along with the agenda and PowerPoint presentations) for these ISR meetings. During the October ISR meetings, AEA and licensing participants identified certain technical memoranda and other information that AEA would file with the Commission by November 15, 2014. In accordance, AEA is filing and distributing the following technical memoranda and other information: • Attachment G: Glacier and Runoff Changes (Study 7.7) and Fluvial Geomorphology (Study 6.5) - Assessment of the Potential for Changes in Sediment Delivery to Watana Reservoir Due to Glacial Surges Technical Memorandum. This technical memorandum documents AEA’s analysis of the potential changes to sediment delivery from the upper Susitna watershed into the Project’s reservoir from glacial surges. • Attachment H: Riparian Instream Flow (Study 8.6) and Fluvial Geomorphology (Study 6.6) - Dam Effects on Downstream Channel and Floodplain Geomorphology and Riparian Plant Communities and Ecosystems − Literature Review Technical Memorandum. This literature review technical 1 Letter from Jeff Wright, FERC Office of Energy Projects, to Wayne Dyok, Alaska Energy Authority, Project No. 14241-000 (issued Jan. 28, 2014). 2 memorandum synthesizes historic physical and biologic data for the Susitna River floodplain vegetation (including 1980s studies), studies of hydro project impacts on downstream floodplain plant communities, and studies of un- impacted floodplain plant community successional processes. • Attachment I: Susitna River Fish Distribution and Abundance Implementation Plan, Appendix 3. Protocol for Site-Specific Gear Type Selection, Version 5. In accordance with the fish distribution and abundance studies, as described in Revised Study Plan (RSP) Sections 9.5 and 9.6 and in the Fish Distribution and Abundance Implementation Plan, this appendix establishes the protocol for site-specific gear type selection for fish surveys. Throughout study plan implementation, AEA has updated this appendix as needed to provide consistent direction to all field teams. Version 1 of Appendix 3 was originally filed with the Fish Distribution and Abundance Implementation Plan in March 2013. That version was updated twice (Versions 2 and 3) during the 2013 field season to accommodate protocol changes that related to FERC’s April 1, 2013 Study Plan Determination, field permits, and lessons learned during study implementation. Version 4 was the protocol used for the 2014 field season and was updated with respect to the prioritization of gear use and based on 2013 data collected. This version herein, Version 5, will be followed during the 2015 field season. • Attachment J: Fish Distribution and Abundance in the Upper and Middle/Lower Susitna River (Studies 9.5 and 9.6): Draft Chinook and Coho Salmon Identification Protocol. This document established a Chinook and coho salmon identification protocol to support accurate and consistent field identification across field teams. It will allow for additional quality control and assurance of field identification calls and for estimation and reporting of any field identification error that may occur in future sampling efforts. • Attachment K: Characterization and Mapping of Aquatic Habitats (9.9), Errata to Initial Study Report Part A - Appendix A, Remote Line Mapping, 2012. This errata provides a corrected version of map book for Remote Line Mapping, 2012. The version filed with the ISR (June 3, 2014) used a data query to build the maps in geomorphic reaches MR-1 to UR-5 that mistakenly did not include side slough habitat, so that no side sloughs were depicted on the Appendix A maps 1 through 21. This version was corrected by including side slough habitat in the data query for geomorphic reaches MR-1 to UR-5. This version now includes side sloughs. • Attachment L: Characterization and Mapping of Aquatic Habitats Study 9.9, Revised Map Book for 2012 Remote Line Mapping. This map book represents an update to the version published on June 3, 2014 with the Study 9.9 Initial Study Report and the errata provided concurrently with this filing (see Attachment K). The maps presented include all macrohabitat and mesohabitat line identifications available in the 2012 Remote Line Mapping ArcGIS 3 shapefile. This map book should be considered a full replacement for previous versions and represents the final product for the 2012 remote line habitat mapping effort. • Attachment M: Study of Fish Passage Barriers in the Middle and Upper Susitna River and Susitna Tributaries (Study 9.12), Fish Passage Criteria Technical Memorandum. This technical memorandum presents a proposed final list of fish species that will be included in the fish barrier analysis as well as depth, leaping and velocity passage criteria for selected fish species. AEA previously consulted with the federal agencies and other licensing participants regarding the information within the technical memorandum during a March 19, 2014 Fisheries Technical Meeting. In addition to the technical memoranda and other information identified above, AEA is filing a short errata (Attachment N) to the Mercury Assessment and Potential for Bioaccumulation Study (Study 5.7), Evaluation of Continued Mercury Monitoring Beyond 2014 Technical Memorandum. This technical memorandum, which was originally filed on September 30, 2014, evaluates the need for continued monitoring of mercury data beyond 2014 and whether the existing data collection efforts are sufficient to satisfy objectives for characterizing baseline mercury conditions in the Susitna River and tributaries (RSP Section 5.7.1). Since the filing of this TM and based upon the ongoing QA/QC of the data reported in that TM, AEA discovered errors in the TM. The attached TM corrects those errors. Additionally, the errata corrects corresponding errors in the Mercury Assessment and Potential for Bioaccumulation presentation presented during the October 16, 2014 ISR meeting. Finally, AEA notes that data collected during the Study Plan implementation, to the extent they have been verified through AEA’s quality assurance and quality control (QAQC) procedures and are publicly available, can be accessed at http://gis.suhydro.org/isr_mtg. On November 14, 2014, AEA posted the following data to this website: • Baseline Water Quality Data (Study 5.5), 2013 QAQC water quality data and DVRs per the Quality Assurance Project Plan. • Breeding Survey Study of Landbirds and Shorebirds (Study 10.16), cumulative 2013-2014 data. • Characterization and Mapping of Aquatic Habitats (Study 9.9), ArcGIS shapefile “ISR_9_9_AQHAB_RemoteLineMapping_2012.shp” used to generate the maps in Attachment L. 4 AEA appreciates the opportunity to provide this additional information to the Commission and licensing participants, which it believes will be helpful in determining the appropriate development of the 2015 study plan as set forth in the ISR. If you have questions concerning this submission please contact me at wdyok@aidea.org or (907) 771-3955. Sincerely, Wayne Dyok Project Manager Alaska Energy Authority Attachments cc: Distribution List (w/o Attachments) Susitna-Watana Hydroelectric Project (FERC No. 14241) Characterization and Mapping of Aquatic Habitats Study 9.9 Revised Map Book for 2012 Remote Line Mapping Prepared for Alaska Energy Authority Prepared by R2 Resource Consultants, Inc. November 2014 REVISED MAP BOOK CHARACTERIZATION AND MAPPING OF AQUATIC HABITATS (9.9) Susitna-Watana Hydroelectric Project Alaska Energy Authority FERC Project No. 14241 Page 1 November 15, 2014 Introduction Since ground-based mapping of 235 miles of river was impractical, remote mapping was combined with ground-based data collection in representative proportions of river habitats to form a habitat characterization of the river (ISR Study 9.9 Section 4.1). This combination of methods allowed for optimum spatial coverage from remote imagery in concert with efficient collection of detailed data at selected habitats by ground-based crews. For remote line mapping all main channel habitats were identified to Level 4 (mesohabitat), although remote imagery was challenging for distinguishing run and glides as well as pools. Off-channel habitat was classified to Level 3 (macrohabitat). This map book represents an update to the version published on June 3, 2014 with the Study 9.9 Initial Study Report and the errata issued on November 15, 2014. In the previous versions of this map book, some macrohabitat units were not easily visible due to overlapping mesohabitat layers, in particular within main channel macrohabitats (main channel, split main channel, multiple-split main channel and side channel). The maps presented herein were updated to be comprehensive of all macrohabitat and mesohabitat line identifications available in the 2012 Remote Line Mapping ArcGIS shapefile. Habitat spelling and naming conventions were updated to reflect 2014 usage. The original hierarchical habitat category structure has been preserved; the changes recommended by the FERC Study Plan Determination of April 1, 2013 (reclassifying Clearwater Plume, Backwater and Beaver Complex habitat from L3 macrohabitat to L4 mesohabitat) are noted in the legend of each map. Tributaries, named and unnamed, are now represented by a point with an associated tributary name as annotation. This map book should be considered a full replacement for previous versions and represents the final product for the 2012 remote line habitat mapping effort. The ArcGIS shapefile “ISR_9_9_AQHAB_RemoteLineMapping_2012.shp” used to generate these maps can be located at: http://gis.suhydro.org/isr_mtg/ 0 10 MilesMiles Legend #*Instream Flow Focus Area Geomorphic Reach !(Impediment Remote Line Mapping Map Extent and Number ^^ProposedProposedWatana DamWatana Dam Talkeetna Anchorage 0 100mi r #* #* #*#* #* #* #* #*#* #* e!( !( !( Impediments Devils Canyon ProposedWatana ReservoirPortageCrDevilCrProposedWatana Dam F o g C r StephanLakeIndianR LaneCrBigLake TsisiCrKosinaCrOshetnaRGooseCrBlackRChunilnaCrTalkeetnaLarsonLake G o ld C rIronCrSheepR SwanLakeTokositn aRChulitnaRiverR iv e r WhiskersCrDeadmanCrTsusenaCrW a t a n a C r CoalCrJayCrTyone R FA-104 FA-113FA-115 FA-128 FA-138 FA-141 FA-144 FA-151 FA-173 FA-184 TalkeetnaTalkeetna TrapperTrapperCreekCreek Parks HwyParks HwyPetersville Rd Petersville Rd SusitnaRiverSusitna R UR-1 UR-2 UR-3 UR-4 UR-5 UR-6 MR-2 MR-3 MR-4 MR-5 MR-6 MR-7 MR-8 MR-1 2 4 3 56 7 8910111213141516171819202122 23 2425262728 3334353637 3839 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 29 303132 Map Key Projection: AK SP Zone 4 NAD 1983Date Created: 11/10/2014Map Author: R2 - Joetta ZablotneyFile: Map_ISR_FA_AQHAB_MSME.mxdOrthophoto Source: 2010 MDA Information Systems, USGS, NASA Macrohabitat (2012) Main Channel Split Main Channel Multiple Split Main Channel Side Channel Side Slough Upland Slough Tributary Mouth Clearwater Plume* Backwater* Beaver Complex* Mesohabitat (2012) Rapid Riffle Run/Glide Pool Map 1 of 55* FERC Study Plan Determination April 1, 2013 changed to mesohabitats.
