Gold Ray Dam Interagency Technical Team Meeting
2
NEPA Update Deconstruction Plans Hydraulic Modeling Next Steps Agenda
3
Upstream habitat (wetlands, fish, frogs, riparian areas) Well levels Downstream domestic water intakes Sediment quality Recreation Economic impacts (fishing and river guides) Alternatives – dam rehab and power generation NEPA Update EA Issues from Scoping Mtg
4
Section 1 – Introduction Section 2 – Purpose and Need and Alternatives Purpose and need – complete No action Alternative 1 – Dam Removal Deconstruction plan Restoration plan Alternative 2 – Dam Rehabilitation Dam, forebay walls, etc. (structural) Fish Ladder Fish Screening Power generation – optional? NEPA Update EA Progress
5
Section 3 – Affected Environment and Environmental Consequences Section 4 - Preparers and Agencies Consulted Section 5 – Abbreviations/Acronyms Section 6 – References NEPA Update EA Progress
6
Dam complex SHPO coordination Determination of eligibility (DOE) nearly complete Likely eligible for National Register Removal likely adverse effect but mitigated Archaeology SHPO coordination done DOE underway – no shovel testing required NEPA Update Cultural Resources
7
Level 1 – based on records and site visit; no testing Look for indicators for contamination Recommend testing locations in power house and former transformer sites NEPA Update Environmental Site Assessment
8
Biological Assessment Content largely completed Confirm the action area Incorporate demo/restoration plan information Project Approach
9
Wetlands Report Submitting 2 wetland reports: Delineation Report and Indirect Wetland Impact Report Reports are drafted; waiting for 2 year event modeling to finalize maps Project Approach
10
Schedule Review draft EA and permit applications in middle of January Draft EA – 30 day review and revision Goals: Submit BA and permit applications in early February EA out for public review in mid to late February Project Approach
