Exclusion and Monitoring Zones: Exclusion and monitoring zones will be established around acoustically active Project components (i.e., impact pile driving and DP thruster use for cable-lay operations). These zones will be established to monitor for ESA-listed species of sea turtles and whales that may enter the Project Area and to adjust Project operations accordingly to prevent exposure of these animals to potentially injurious levels of underwater noise. Exclusion and monitoring zones are not being established for Atlantic sturgeon because this species occurs only under the water surface and visual observers will not be able to detect the presence of Atlantic sturgeon in the Project Area and no remote sensing technology that could detect Atlantic sturgeon is feasible for deployment in the area.

a. Impact Pile Driving ofWTG Foundations- Prior to the onset of pile driving, when the 200-kilojoule (kJ) impact hammer is in use, an initial 200-m radius exclusion zone will be established around each jacket foundation. In addition, an initial monitoring zone extending 3.6 km (radius) from the pile will be monitored for each pile during impact pile driving activities utilizing the 200-kJ impact pile driving hammer. During the final phases of pile installation, when a 600-kJ impact hammer will be used, the exclusion zone will be expanded to the maximum radial distance of approximately 600 m. The monitoring zone will be expanded to the maximum radial distance of approximately 7 km. These distances are expected to equate to where 180 dBRMs and 160 dBRMs isopleth extend. DWBI will follow ramp-up and shutdown procedures in accordance with these monitoring zones (see below for further details).

b. Dynamic Position (DP) Vessel during Cable Installation- DP vessel use during cable installation will not produce sound levels at 180 dBRMs beyond 1 m from the source and thus, an exclusion zone will not be established. A monitoring zone, based on the extent to the 160 dBRMS isopleth, will be established around the DP vessel. The monitoring zone will extend an estimated 21 m from the source (i.e., DP vessel). All marine mammal sightings, including those beyond the 160 dBRMs isopleth will be recorded.

27. Field Verification of Monitoring and Exclusion Zones:

a. Impact Pile Driving ofWTG Foundations- Field verification of the initial 200-m radius exclusion zone and the 3.6-km radius monitoring zone for the 200-kJ impact pile driving hammer, as well as the 600-m radius exclusion zone and 7-km radius monitoring zone for 600-kJ impact pile driving hammer, will be conducted. Acoustic measurements will include the driving of the last half (deepest pile segment) for any given open-water pile and will include measurements from two reference locations at two water depths (a depth at mid-water and a depth at approximately 1m above the seafloor). If the field measurements determine that the actual 180 dBRMs and 160 dBRMs zones of influence are less than or extend beyond the proposed exclusion zone and monitoring zone radii, a new zone(s) will be established accordingly. The Corps and NMFS will be notified within 24 hours whenever any new exclusion and/or monitoring zone are established by DWBI that extends beyond the initially proposed radii. Implementation of the revised zone(s) smaller than the proposed radii will be contingent upon Corps and NMFS review and approval. In the event that a smaller zone(s) is determined to be appropriate, DWBI will continue to use the originally proposed zone(s) until agency approval is given.

b. DP Vessel during Cable Installation- Field verification of the preliminary 21-m radius monitoring zone (i.e., that the 160 dBRMs isopleth does not extend beyond 21-m) associated with DP vessel thruster use during cable installation will be performed using acoustic measurements from two reference locations at two water depths (a depth at mid-water and a depth at approximately 1-m above the seafloor). As necessary, the monitoring zone will be modified and implemented as described for impact pile driving).

28. Protected Species Observers: a. All observations for whales and sea turtles in the exclusion and monitoring zones

will be performed by NMFS-approved protected species observers (PSO). Observer qualifications will include direct field experience on a marine mammal/sea turtle observation vessel and/or aerial surveys in the Atlantic Ocean/Gulf of Mexico. It is anticipated a minimum of two PSOs will be stationed aboard each noise producing construction support vessel (e. g., den-ick barge, jackup barge, and cable-lay vessel). To increase the potential for detection, given the distance of the monitoring zone associated with the impact pile driving, at least two additional PSOs will be stationed aboard an observation vessel dedicated to

patrolling the monitoring zone while continuously searching for the presence of ESA listed species (i.e., whales and sea turtles; in the offshore marine environment, visual surface detection of Atlantic sturgeon is not feasible). Each PSO will monitor 360 degrees ofthe field ofvision. Each PSO will follow the specified monitoring period for each of the following construction activities:

1. Impact Pile Driving ofWTG Foundations- The PSOs will begin observation of the monitoring zone for at least 30 minutes prior to the softstmi of impact pile driving (see below for fmiher details). Use of pile driving equipment will not begin until the associated exclusion zone is clear of all ESA-listed whales and sea turtles for at least 30 minutes. Initial monitoring of the exclusion and monitoring zones prior to soft-stmi will be conducted with the assistance of night vision equipment to account for dark conditions at or just prior to dawn. In addition, soft-start of construction equipment, as described below, will not be initiated if the monitoring zone cannot be adequately monitored (i.e., obscured by fog, inclement weather) for a 30-minute period. If a soft-start has been initiated before the onset of inclement weather, activities may continue through these periods if deemed necessary to ensure the safety and integrity of the Project. Observation of both the exclusion and monitoring zones will continue throughout the construction activity and will end approximately 30 minutes after use of noise-producing equipment stops operation.

n. DP Vessel during Cable Installation- PSOs stationed on the DP vessel will begin observation of the monitoring zone as the vessel initially leaves the dock. Observations of the monitoring zone will continue throughout the construction activity and will end after the DP vessel has returned to dock.

b. For each of the two construction activities (impact pile driving and DP thruster use during cable installation), PSOs, using binoculars, will estimate distances to whales and sea turtles either visually, using laser range finders, or by using reticle binoculars during daylight hours. It is important to note that all pile driving activity will occur only during daylight hours. As cable-laying activities will operate 24 hours a day, during night operations, night vision binoculars will be used. If higher vantage points (greater than 25ft) are available, distances can be measured using inclinometers. Position data will be recorded using hand-held or vessel global positioning system (GPS) units for each sighting, vessel position change, and any environmental change.

c. For monitoring established exclusion and monitoring zones, each PSO stationed on or in proximity to the noise-producing vessel or location will scan the surrounding area for visual indication of whale and sea turtle presence that may enter the zones. Observations will take place from the highest available vantage point on the associated operational platform (e.g., suppmi vessel, barge or tug; estimated to be over 20 or more feet above the waterline). General360-degree scanning will occur during the monitoring periods, and target scanning by the PSO will occur when alerted of the presence of a whale or sea turtle.

d. Data on all observations will be recorded based on standard PSO collection requirements. This will include dates and locatiops of construction operations; time of observation, location and weather; details of whale and sea turtle sightings (e.g., species, age classification [ifknown], numbers, behavior); and details of any observed behavioral disturbances or injury/mortality. In addition, prior to initiation of construction work, all crew members on barges, tugs and support vessels, will undergo environmental training, a component of which will focus on the procedures for sighting and protection of whales and sea turtles. A briefing will also be conducted between the construction supervisors and crews, the PSOs and DWBI. The purpose of the briefing will be to establish responsibilities of each party, define the chains of command, discuss communication procedures, provide an overview of monitoring purposes, and review operational procedures. The DWBI Construction Compliance Managers (or other authorized individual) will have the authority to stop or delay impact pile driving activities, if deemed necessary. New personnel will be briefed as they join the work in progress.

29. Ramp-up/Soft-Start Procedures: A ramp-up (also lmown as a soft-start) will be used for noise-producing construction equipment capable of adjusting energy levels (i.e., pile driving operations). The DP vessel thrusters will be engaged from the time the vessel leaves the dock. Therefore, there is no opportunity to engage in a ramp-up procedure. The ramp-up procedure for noise-producing equipment utilized during impact pile driving of the WTG foundations is described below:

a. Impact Pile Driving of the WTG Foundations: The ramp-up procedure for noiseproducing equipment utilized during impact pile driving of the WIG foundations will not be initiated if the monitoring zone cannot be adequately monitored (i.e., obscured by fog, inclement weather, poor lighting conditions) for a 30-minute period. If a soft-start has been initiated before the onset of inclement weather, activities may continue through these periods if deemed necessary to ensure the safety and integrity of the Project. A ramp-up will be used at the beginning of each pile segment during impact pile driving in order to provide additional protection to Atlantic sturgeon, whales and sea turtles near the Project Area by allowing them to vacate the area prior to the commencement of pile driving activities. The ramp-up procedures require an initial set of three strikes from the impact hammer at 40 percent energy with a one minute waiting period between subsequent three-strike sets. The procedure will be repeated two additional times. If whales or sea tmiles are sighted within the impact pile driving monitoring zone prior to or during the soft-stati, activities will be delayed until the animal(s) has moved outside the monitoring zone and no whales or sea turtles are sighted for a period of 30 minutes.

30. Shutdown Procedures: The monitoring zone around the noise-producing activities (impact pile driving and DP thruster use during cable installation) will be monitored, as previously described, by PSOs for the presence of whales and sea turtles before, during and after any noise-producing activity. PSOs will work in coordination with DWBI's

Construction Compliance Managers (or other authorized individual) to stop or delay any construction activity, if deemed necessary. The following outlines the shutdown procedures:

a. Impact Pile Driving ofWTG Foundations- For impact pile driving, from an engineering standpoint, any significant stoppage of driving progress will allow time for displaced sediments along the piling surface areas to consolidate and bind. Attempts to restart the driving of a stopped piling may be unsuccessful and create a situation where a piling is permanently bound in a partially driven position. In the event that a whale or sea turtle is observed within or approaching the monitoring zone during impact pile driving, PSOs will immediately report the sighting to the on-site Construction Compliance Manager (or other authorized individual). Upon this notification, the hammer energy will be reduced by 50 percent to a "ramp-up" level. This reduction in hammer energy will effectively reduce the potential for exposure of whales, sea turtles, and Atlantic sturgeon to sound energy, proportional to the reduction in force; however, established exclusion and monitoring zones will remain constant for monitoring purposes. By maintaining impact pile driving at a reduced energy level, momentum in piling penetration can be maintained minimizing risk to both Project integrity and to whales, Atlantic sturgeon, and sea turtles.

After decreasing impact pile driving energy, PSOs will continue to monitor whale and/or sea turtle behavior and determine if the animal(s) is moving towards or away from the exclusion zone. If the animal(s) continues to move towards the sound source, then impact piling operations will be halted prior to the animal entering the exclusion zone. Ramp-up procedures for impact pile driving may be initiated when PSOs report that the monitoring zone has remained clear of whales and/or sea turtles for a minimum of 30 minutes since the last sighting.

31. Pile Driving- Time of Day Restrictions: Impact pile driving for jacket foundation installation will occur during daylight hours starting approximately 30 minutes after dawn and ending 30 minutes prior to dusk unless a situation arises where ceasing the pile driving activity would compromise safety (both human health and environmental) and/or the integrity of the Project. If a soft-start has been initiated prior to the onset of inclement weather (e.g., fog, severe rain events), the pile driving of that segment may be completed. No new pile driving activities will be initiated until 30 minutes after dawn or after the inclement weather has passed.

32. Reporting: DWBI will provide the following reports during construction activities:

a. DWBI will contact the Corps and NMFS at least 24 hours prior to the commencement of construction activities and again within 24 hours of the completion of the activity.

b. DWBI will contact the Corps and NMFS within 24 hours of establishing any exclusion and/or monitoring zone. Within seven days of establishing exclusion and/or monitoring zones, DWBI will provide a report to the Corps and NMFS detailing the field-verification measurements. This report will include the

following information: a detailed account of the levels, durations, and spectral characteristics of the impact pile driving sounds, DP thruster use, and the peak, RMS, and energy levels of the sound pulses and their durations as a function of distance, water depth, and tidal cycle.

c. DWBI must notify Corps and NMFS within 24 hours of receiving any field monitoring results which indicate that any exclusion or monitoring zones should be modified (i.e., due to in-field sound monitoring suggesting that model results. were too big or too small). No changes will be made to the exclusion or monitoring zones without written (e-mail) approval from the Corps and NMFS.

d. Any observed behavioral reactions (e.g., animals departing the area) or injury or mortality to any marine mammals, Atlantic sturgeon, or sea turtles must be repmied to the Corps and NMFS within 24 hours of observation. If any sturgeon are observed, these instances will also be reported to the Corps and NMFS ([email protected]) within 24 hours.

e. A final technical report will be provided to the Corps and NMFS within 120 days after completion of the construction activities. This repmi must provide full documentation of methods and monitoring protocols (including verification of the sound levels actually produced within the exclusion and monitoring zones), summarizes the data recorded during monitoring, and comparing these values to the estimates of listed marine mammals and sea turtles that were expected to be exposed to disturbing levels of noise during construction activities, and provides an interpretation of the results and effectiveness of all monitoring tasks.

33. Strike Avoidance: All vessels associated with the construction, operation, maintenance and repair, and decommissioning of the BIWF will adhere to NMFS guidelines for marine mammal ship strike avoidance (see (http://www.nmfs.noaa.gov/pr/pdfs/education/viewing nmiheast.pdf), including maintaining a distance of at least 500 yards from right whales, at least 100 ft from all other whales, and having dedicated lookouts and/or protected species observers posted on all vessels who will communicate with the captain to ensure that all measures to avoid whales are taken.

PSOs will be placed on vessels with noise-producing equipment (e.g., vessels with the pile driver and the DP vessels) and vessels assigned to actively observe the Project's established exclusion and monitoring zones through construction. Other vessels will have a dedicated lookout to watch for whales and sea tmiles and to communicate with the captain.

34. Geophysical Surveys Mitigation and Monitoring: DWBI will use the following measures during all geophysical surveys (i.e., multi-beam sonar and sub-bottom profiler [chirp]):

a. Implementation of Ramp-Up: At the start of each survey day, instruments that have the capability of running at variable power levels and operate at a frequency detectable by ESA-listed species will initially be operated at low-levels, then gradually increased to minimum necessary power requirements for quality data

collection. This allows any listed species capable of detecting this noise to depart the area before full-power surveying commences. Surveys will not commence (i.e., ramp-up) when the exclusion zone cannot be effectively monitored.

b. Establishment of Exclusion Zone: Whenever multi-beam sonar or the chirp is in use, a 300-m radius exclusion zone (from the source) will be established around the operating vessel or the towed survey device. The sounds produced by this equipment cannot be perceived by sea tmiles or Atlantic sturgeon because the frequency is too high. Therefore, the exclusion zone will be maintained for listed whales. For example, if a sound source is towed 30m behind the survey vessel, the monitored area from the vessel will be out to 330m (or 300m from the source). The 300-m exclusion zone encompasses the 160 dBRMs isopleth, which for either geophysical survey device, is expected to occur within 150m or less from the operating device.

c. Visual Monitoring of the Exclusion Zones: The exclusion zone will be monitored by a trained Environmental Compliance Monitor who will keep vigilant watch for the presence of marine mammals within the exclusion zone. The exclusion zone will be monitored for 30 minutes prior to the ramp-up of sound sources. If the exclusion zone is obscured by fog or poor lighting conditions, surveying utilizing noise-producing equipment will not be initiated until the entire exclusion zone is visible for the 30-minute period. If marine mammals are observed within the 300-m safety exclusion zones during 30-minute period and before the ramp-up begins, surveying utilizing noise-producing equipment will be delayed until they move out of the area.

The Environmental Compliance Monitor assigned to the survey vessel, as well as all individuals onboard the survey vessel responsible for navigation duties, will receive training on marine mammal and sea tmile sighting and reporting and vessel strike avoidance measures. The training course will be modeled after a NMFS-approved marine mammal and sea turtle training program. The training will include details on the federal laws and regulations for protected species (ship strike infmmation, migratory routes, and seasonal abundance), as well as training on species identification.

All sightings ofNMFS-listed species will be recorded on an established NMFSapproved log sheet by the Environmental Compliance Monitor. The following data will be recorded:

1. Dates and location of operations; 11. Weather and sea-state conditions;

111. Time of observation; IV. Approximate location (latitude and longitude) at the time of the sighting; v. Details of sighting (species, numbers, behavior);

v1. General direction and distance of sighting from the vessel; VII. Activity of the vessels at the time of sighting; and

vm. Action taken by the Environmental Compliance Monitor.

All observation data will be provided to NMFS within 60 days of the completion of surveys. In addition, during all survey operations DWBI will report all sightings ofESA-listed species, regardless of condition, to NMFS ([email protected]) within 24 hours of the observation and record as much information as possible (e.g., species, size, decomposition state, obvious injuries etc.).

d. ShutDown: If a listed whale is spotted within or transiting towards the exclusion zone when equipment is operating that can be heard by that individual (i.e., the chirp), an immediate shutdown of the equipment will occur. Subsequent restart or ramp-up of equipment will occur only after the whale has cleared the safety exclusion zone.

Sea Turtles and Atlantic Sturgeon: 35. All endangered species observers contracted by DWBI must be approved by the Corps and NMFS. DWBI shall provide the Corps, and the Corps shall transmit to NMFS, the names and resumes of all endangered species monitors to be employed at the Project site at least 30 days prior to the start ofWTG construction. No observer shall work at the Project site without written approval ofNMFS. If during Project construction or DP vessel operations, additional endangered species monitors are necessary, DWBI shall provide those names and resumes, and the Corps shall transmit those names and resumes to NMFS for approval at least 10 days prior to the date that they are expected to start work at the site.

36. Designated exclusion zones for all noise-producing activities must be monitored by NMFS-approved observers. The exclusion zone is considered that area ensonified by injurious levels (i.e., underwater noise levels greater than or equal to 180 dBRMS). Monitoring shall be as follows:

a. Impact Pile Driving Operations: Observers must begin monitoring the exclusion zone at least 60 minutes prior to the initiation of soft-start pile driving. Full energy pile driving must not begin until the zone is clear of all sea turtles for at least 60 minutes. Monitoring will continue through the pile driving period and end approximately 60 minutes after pile driving is completed. Observers must notify operators if any sea turtles appear to be moving toward the exclusion zone, so that operations can be adjusted (i.e., pile driving energy reduced) to minimize the size of the exclusion zone. If the latter occurs, the observer must monitor the area within and near the exclusion zone for 60 minutes, and if clear after 60 minutes after the last sighting, notify the operator that full energy pile driving may resume.

b. DP vessel operations: Observers will begin monitoring the exclusion zone as soon as the vessel leaves the dock and continue throughout the construction activity. Observers must notify the vessel operator if any sea turtles appear to be moving toward the exclusion zone, so that operations can be adjusted (i.e., reduced DP thruster energy) to minimize the size of the exclusion zone. If the latter occurs, the observer must monitor the area within and near the exclusion zone for 60

minutes, and if clear after 60 minutes of the last sighting, notifY the vessel operator that full energy thruster use may resume. As DP vessels will be operational for 24 hours, at least two observers shall be onboard the vessel, working a 12-hour on, 12-hour off schedule. That observer working the night shift needs to be provided night-vision binoculars.

37. Field verification of modeled noise levels for injury or mortality must be undertaken and must be conducted throughout the work period to confirm modeled sound levels. This needs to be conducted for: (1) impact pile driving operations; and (2) DP thruster use. Acoustic verification and monitoring must be conducted during impact pile driving (for the installation of each WTG foundation pile) and DP thruster use to ensure the exclusion zone is appropriately defined and thus, monitored by the observer required in Condition 39. Acoustic monitoring must be sufficient to determine source levels (i.e., within 1 m of the source), as well as the following:

a. Atlantic sturgeon acoustic injury thresholds: Distance to the 206 peak sound level ( dBPeak) and 187 cumulative sound exposure level ( dBcsEL) isopleths.

b. Sea turtle acoustic injury threshold: Distance to the 207 dBRMs isopleth.

Results of this monitoring must be reported, via email, ([email protected]) to NMFS. For pile driving operations, results must be provided to NMFS prior to the installation ofthe next pile or within 24 hours of installation, whichever is sooner. For DP vessel operation, results must be provided every 24 hours. If there is any indication that injury thresholds have been attained in a manner not considered in the NMFS Biological Opinion dated January 30, 2014 (i.e., extent of206 dBPeak or 187 dBcsEL [Atlantic sturgeon]; 207 dBRMs [sea turtles]), NMFS must be contacted immediately.

38. Field verification of modeled noise levels for behavioral disturbance must be undertaken and must be conducted throughout the work period to confirm modeled sound levels. This needs to be conducted for impact pile-driving operations. These reasonable and prudent measures functions as a surrogate for monitoring incidental take. Acoustic verification and monitoring must be conducted during impact pile driving for the installation of each WTG foundation pile. Acoustic monitoring must be sufficient to dete1mine source levels (i.e., within 1m of the source), as well as the following:

a. Atlantic sturgeon acoustic behavioral disturbance thresholds: Distance to the 150 dBRMS isopleth.

b. Sea turtle acoustic behavioral disturbance threshold: Distance to the 166 dBRMs isopleth.

Results of this monitoring must be repmied, via email ([email protected]) to NMFS. For pile driving operations, results must be provided to NMFS prior to the installation of the next pile or within 24 hours of installation, whichever is sooner.

39. Any ESA listed species, including Atlantic sturgeon, observed during activities authorized under this Permit must be recorded, with information submitted to NMFS within 30 days. Any dead or injured individuals must be reported to NMFS within 24 hours. In the event of any observations of dead sea turtles or Atlantic sturgeon, dead specimens should be collected with a net and preserved (refrigerate or freeze) until disposal procedures are

discussed with NMFS.

40. Reasonable attempts should be made to collect any dead sea turtles or sturgeon. These individuals shall be held in cold storage until disposition can be discussed with NMFS. The Corps or Deepwater Wind must contact NMFS within 24 hours of any observations of dead or injured ESA listed species. NMFS will provide contact information when alerted of the statt of project activity. Until alerted otherwise, the USACE should contact the Section 7 Coordinator by phone (978)281-9328 or fax 978-281-9394). Take infmmation should also be repmted by e-mail to: [email protected].

Other Stipulations: 41. N mth Atlantic Right Whales Impact A voidance: In order to avoid potential impacts to Nmth Atlantic Right Whales, impact driving of wind turbine foundations shall not occur between November 1 and April 30th of any calendar year(s).

42. Nearshore Transmission Cable Burial Depth: The minimum transmission cable burial depth between Mean High Water (MHW) and Mean Low Water (ML W) shall be Elevation minus 10 feet ML W. Transmission Cable installation depth below beaches and dunes at cable landing locations shall also achieve a minimum burial depth of 1 0' below the beach sediment surface. Burial depth below dunes shall be based on the elevation of the beach at the base of the dunes and shall not include the dune height in the burial depth measurement. A post installation survey, stamped by a RI registered Land Surveyor or Engineer, that provides the elevation of the top of the cable on the mean low water datum and horizontally on the RI State Plane coordinate system shall be submitted to the Corps to confirm this requirement has been met. This survey shall be submitted within 15 days of transmission cable installation at the beach landing locations.

43. Post Construction Avian Monitoring: Post construction avian monitoring will be as described in the modified Avian and Bat Post Construction Monitoring Plan dated February 28, 2014.

44. Environmental Compliance Monitor: DWBI shall employ an Environmental Compliance Monitor (ECM) to monitor environmental compliance during all construction activities associated with the BIWF. The ECM shall be a third-party entity hired by DWBI.

45. Cable Location and Scour Protection: Within 15 days of completing the installation of the submarine transmission cable, DWBI shall submit a post-construction survey, stamped by a Rhode Island-registered Professional Land Surveyor or Engineer, of the actual cable location and the proposed cable easement with State Plane and LAT /LON coordinates for the cable angle points, easement comers I angle points of all scour protection matting (concrete filled bags, concrete mats, stone, etc.) installed on the ocean floor to protect the transmission cable. If the area of the ocean bottom impacted by protective armoring exceeds the 2.1 acres of total ocean bottom coverage estimated within the Environmental Report/COP, the Corps may require marine habitat compensation to be determined after submission of the post-installation survey.
