2 Deepwater Wind was awarded a 20 year contract (PPA) to supply power to LIPA in East Hampton 90 MW wind farm located 30 miles east of Montauk Will power 50,000 typical homes Allows LIPA to defer construction of fossil-fired generation in East Hampton

3 Project Timeline and Consultations January 25, 2017 March 31, 2017 April 24, 2017 June 14, 2017 June 22, 2017 LIPA Board Approves Project Selection and PPA NY State Comptroller Approves PPA Presentation to the East Hampton Trustees Meeting with Harbor Management Committee Meeting with Harbor Management Committee

4 Tonight s Agenda Process for Permitting the South Fork Wind Farm Opportunities for Stakeholder Involvement Applicable Science from the Block Island Wind Farm Learnings from the Block Island Wind Farm for Fisheries and Marine Habitat Process for Selection of Turbine Locations and Cable Route(s) Process for Establishing Community Benefits

5 In response to community input, we are investigating multiple routes to deliver power to East Hampton

6 Permitting and Site Control involves many Municipal, State, and Federal Agencies 6

7 Project Development Timeline Stakeholder outreach begins: BOEM Science and Stakeholder Involvement Science begins, ongoing Detailed science and engineering studies Permit application submission Permit review, science & engineering assessment Expected permit approval, construction begins Construction completed, SFWF operational Post- construction scientific monitoring

10 Fisheries Survey Timeline at BIWF Two Years Baseline Construction One year Foundation Installation One year Turbine Installation Post-Construction Two Years 10

11 Demersal Trawl Survey: Scope Conducted on commercial trawler from Pt. Judith Otter trawl consistent with other regional studies 20 minute tows, once a month Three Study Blocks Reference South 2 tows Reference East 2 tows Area of Potential Effect 2 tows Six Years of Surveys 2 years before construction 2 years during construction 2 years after construction 11

12 Demersal Trawl Survey: Results Baseline (filled symbols) vs. Construction (open symbols) No change in catch except skate, dogfish, and windowpane higher during construction REFE significantly higher catch than REFS No consistent difference between APE and Reference Sites Preliminary completing first post-construction survey in September

13 Condition and Stomach Contents: winter flounder, summer flounder, silver hake, red hake, spotted hake, and Atlantic cod Condition not affected by construction activity Prey availability not affected by construction activity 13

14 Lobster Trap Survey: Scope Commercial lobster boats from Pt. Judith and Newport Design consistent with other regional studies 5 night soak, twice a month Vented and ventless traps Four Study Blocks 2 Near Field 2 Far Field Six Years of Surveys: May October years before construction 2 years during construction 2 years after construction 14

15 Lobster Trap Survey: Results Preliminary completing first post-construction survey in October 2017 No negative impact on lobster abundances in the vicinity of the wind farm from construction Catch higher during construction than before at near field Catch highest in 2016 at all sites Far field higher catch than Near field Far field Near field 15

17 Benthic Assessment Sediment Profile Imaging (SPI) and Plan View (PV) High resolution imagery of seafloor Grab samples for laboratory testing Characterize baseline ecological conditions and seafloor habitats SPI/PV camera system Deployment of SPI/PV system

18 Hard Bottom Survey: Scope Assessment of barge anchoring activity on valuable hard bottom habitat Required as condition of construction permit Multi-scale data: Acoustic multi-beam data Towed video transects Plan-view images 3 Monitoring Areas 2 Controls 1 Potential Impact Targeted Sampling near anchor features 3 Surveys near WTG #5: Before construction (August 2015) After construction (March 2016) 1 year after construction (August 2016) 18

19 Hard Bottom Survey: Results Anchoring activity avoided the most valuable habitat areas, as planned Anchor scars were detected in patchy moderate value hard bottom habitat using acoustic data Anchor scars were recorded with video March 2016 Recolonization (<1 yr) of anchor scar edges by existing local fauna No negative effects were observed As a result, the requirement for monitoring 3 & 5 years after construction was waived by federal and state permitting agencies 19

20 Recreational Boating Survey: Scope Gathered information on recreational boating intensity Three year survey before, during, and after construction Two week-long studies per year Block Island Race Week Independence Day Monitor potential effects due to construction and operation Compare intensity of use between BIWF and adjacent areas Boating intensity recorded from fixed viewpoint at Southeast Light 210 view field out to 3.5 NM from shore 20

21 Recreational Boating Survey: Results Motorboat fishing is most prevalent recreational boating activity High interest in viewing turbines from boats Fishing activity at Southeast Ledge shifted to turbine area 2015 Baseline Year 2017 Post-Construction Year 21

22 Avian & Bat Surveys Pre-construction: Radar High Definition Aerial Videography Boat based point count / visual observation surveys Onshore point count surveys Acoustics Beached bird surveys Surveys at beach landing locations During construction: Beached bird surveys Vessel mounted acoustic recorders Post-construction: Radar Thermal Camera Turbine mounted acoustic recorders Boat based point count / visual observation surveys 22

23 Marine Mammal Voluntary Protection Voluntary time of year restriction on construction Protected Species Observers 23

24 Key Lessons Learned from BIWF Stakeholder engagement: early and often Scientific monitoring needs to be specific to conditions at site: habitat, resources, construction Monitoring must be carefully coordinated with construction activities Minimize effects with Management tools Monitor response of habitat and resources to ensure management is successful Construction can be successful in complex bottom with minimal disturbance to habitat and resources 24

25 Planning for Science at SFWF Example Surveys: Archeological (Marine and Terrestrial) Visual Impact Assessment (including historic properties) Wetland Delineation Sensitive Habitat Surveys Avian and Bat Surveys Benthic Surveys Fish and Fisheries Surveys Marine Mammal and Sea Turtle Surveys Example Desktop Studies: EMF modeling EFH Analysis Navigational Risk Assessment Air Emissions Analysis Underwater and In-Air Acoustic Modeling Marine Mammal Risk Assessment Sediment Transport Modeling 25

26 Geophysical and Geotechnical Multibeam depth sounder to determine water depths and general bottom topography. Seafloor imaging (side scan sonar survey) to identify natural and man-made acoustic targets; Magnetic intensity measurements for detecting ferrous objects; Subbottom profiler to map the near surface (chirp) and deeper (boomer) stratigraphy; Geotechnical to collect sediment samples to ground-truth geophysical information and assess technical properties (e.g. thermal resistivity) 26

27 Benthic Assessment Reconnaissance survey during G&G Characterize baseline ecological conditions and seafloor habitats Full benthic assessment after geophysical survey

28 What s next? Stakeholder engagement continues Review geophysical, habitat, fisheries, and archeological data from site and cable routes Investigate landing sites Review by federal and state agencies Preparation of permit applications 28

29 Block Island Wind Farm Process for Establishing Community Benefits Objectives of a Community Benefits Program: 1. Contribute to the long-term wellbeing of the community 2. Leave any disturbed areas better than we found them 3. Provide Transparency and Accountability Specific Benefits Established Based on Dialog with the Community Scarborough Beach
