National Environmental Policy Act – Annotated Environmental Impact Statement Template

Project Overview

CSA worked with BOEM and other Federal agencies to update the existing annotated template for Environmental Impact Statements (EISs) for the Atlantic Outer Continental Shelf (OCS) Construction and Operations Plans (COPs) for offshore wind energy. The primary changes to the existing template were:

▪ Streamline EISs in compliance with Secretarial Order 335 Streamlining National Environmental Policy Act Reviews and Implementation of Executive Order 13807, “Establishing Discipline and Accountability in the Environmental Review and Permitting Process for Infrastructure Projects”);

▪ Accommodate use of the NEPA process for purposes of compliance with Section 106 of the National Historic Preservation Act, pursuant to 36 CFR § 800.8(c);

▪ Accommodate use of the NEPA process for Marine Mammal Protection Act authorizations related to the project;

▪ Ensure consistency across EISs as the Template will be used by BOEM staff and provided to EIS contractors; accommodate design envelopes;

▪ Utilize the no action baseline approach outlined in Magee and Nesbit (2008) and Ecclestone (2011); and

▪ Identify EIS sections that can be pre-populated by BOEM, including sections that are common across multiple projects (e.g., regional setting descriptions and cumulative activities scenario).

This update included conducting interviews with BOEM staff and other Federal agencies that are Cooperating agencies for the preparation of the EISs to gather their input (e.g., concerns, required information to be included in the EIS, changes desired to meet their regulatory concerns). In addition, the Template included revisions to reflect the updated Council on Environmental Quality NEPA guidance. Once all the agency interviews were held and consultations with BOEM regarding the results of those interviews, CSA updated the Annotated EIS Template to reflect the desired changes and incorporate the updated guidance. This template will be used by BOEM third party EIS contractors.

Geophysical and Geotechnical Survey for Ocean-dredged Material Disposal Site Expansion Areas in the US Gulf of

Mexico

In July and August 2019, and in February 2020, CSA Ocean Sciences Inc. (CSA) conducted high-resolution geophysical surveys and sediment sampling within two proposed ocean dredged material disposal site (ODMDS) expansion areas located off Port Aransas and South Padre Island, Texas.

Additionally, sediment sampling was conducted in the ODMDS off Matagorda, Texas.

The geophysical sensor package included a multibeam sonar to record bathymetry and acoustic backscatter, a dual-frequency side-scan sonar, marine magnetometer, as well as a sound velocity profiler and installed tide gauges.

Horizontal positioning was improved via real-time kinematic (RTK) corrections. Vertical corrections were implemented via RTK tides and daily reference to National Oceanic and Atmospheric Administration (NOAA) tidal monitoring stations. Processed data products were interpreted to provide corrected bathymetric depth maps (reported in ft, MLLW), multibeam backscatter mosaics, side-scan sonar mosaics, and interpolated marine magnetic data.

Working in concert with EPA scientific crew, sediment and macrofauna samples were collected to characterize current benthic conditions within and outside ODMDS boundaries of Matagorda, Corpus Christ, and Brazos Island Harbor. A total of 90 samples were collected for physiochemical analysis and onboard sediment sieving for macrofauna identification.

Development of Environmental Observations (RODEO) II”

CSA Ocean Sciences Inc. (CSA) is under contract by the Bureau of Ocean Energy Management (BOEM) for an Indefinite Delivery/Indefinite Quantity (IDIQ) for the “Real-Time Opportunity of Development of Environmental Observations (RODEO) II” and was awarded the first Task Order entitled “Continuation of Observations at Block Island (BIWF)”.

The principal objective of this benthic monitoring was to collect data documenting the condition of the seafloor and associated benthic habitats in areas disturbed by construction of the BIWF and assess any alteration and/or recovery of these habitats post-construction of the BIWF. This effort is the continuation of benthic monitoring around wind turbine generator (WTG) foundations and within control areas, as well as collection of epibenthic fauna from foundations. The results of this monitoring effort is being compared to the previous BIWF seafloor monitoring results to effectively evaluate disturbance and recovery over the time period since construction of the BIWF which commenced initial operations in December 2016.

The BIWF benthic monitoring survey combined grab sampling and visual imagery to characterize the current state of benthic habitats around three of the five WTGs, as well as in three pre-determined control areas in biotopes similar to that where the WTG are located. Further, CSA performed epifaunal sampling on the WTG foundations to characterize the epifaunal communities associated with the introduced WTG foundation. Comparison to previous studies allows for an assessment of temporal changes to epifaunal communities, as well as the surrounding benthic habitats.

Benthic Habitat Assessment and Mitigation for Sensitive Resources on Grand Bahama Island

CSA Ocean Sciences Inc. (CSA) conducted a multi-phase project on the south coast of Grand Bahama Island to support an Environmental Impact Statement (EIS) and other marine management aspects associated with a coastal development project. CSA provided a benthic habitat characterization and mapping survey followed by a large-scale coral relocation effort completed prior to dredge activities to support the development project.

To assess the potential for project-related impacts that could require mitigation, CSA conducted a benthic resources survey in the area within the dredge footprint in 2019. Detailed aerial imagery was collected via an unmanned aerial vehicle (AUV) and verified (groundtruthed) by marine scientists to create geospatial polygon features in GIS in order to calculate the aerial extent of each habitat type to support mitigation planning efforts. Each habitat was then characterized by AAUS certified marine scientists using a spatially balanced, random sampling design that utilized qualitative assessments of benthic habitats, photo and video data collection, and random quadrat sampling for quantitative assessment of percent cover of abiotic and biotic functional groups, and enumeration, size-class designation, and health assessment of all observed stony corals and octocorals. All Endangered Species Act (ESA) and International Union for the Conservation of Nature (IUCN) listed species encountered during the survey were identified to species and the geographic location recorded.

Coral relocation was completed in Sep. 2022 by a dive team composed of trained and experienced marine biologists and scientific divers from CSA, supported by technical divers, two captained vessels, and vessel-based support staff. Over 5,500 viable stony corals and more than 1,800 octocorals were removed from within the impact area and securely reattached to boulders in a Mitigation Reef Site established to the west of the project area. A general assessment survey of habitat conditions downdrift of the project area was also conducted prior to initiation of construction activities.

Identifying Sensitive, Hard-Bottom Habitat in Shallow, Federal Waters of the Gulf of Mexico

The Bureau of Ocean Energy Management (BOEM) contracted CSA Ocean Sciences Inc. (CSA) to provide support to BOEM’s Office of Environment to identify and document the location of sensitive, hard-bottom habitat in shallow, Federal waters of the Gulf of Mexico (GOM) Outer Continental Shelf (OCS).

Much of the GOM seafloor is comprised of soft sediments, but there are four different shallow (<300 m water depth), hard-bottom habitat types described in Notice to Lessees (NTL) No. 2009-G39: topographic features, pinnacle trend features, live bottom/low relief features, and potentially sensitive biological features (PSBF). The first three habitats are defined by their biological and geophysical characteristics. PSBF is a general term for all other sensitive, hard-bottom habitats with moderate to high relief (≥2 m); identifying these types of habitats was the focus for this project.

These hard-bottom habitats attract corals and encrusting organisms, provide shelter for invertebrates and fish, are often high in biodiversity and biomass, and sensitive to disturbance. Identification these hard-bottom habitats is important to avoid or mitigate potential impacts to these benthic resources by BOEM-regulated activities.

BOEM’s understanding of the location of PSBFs and other sensitive, hard-bottom habitats in GOM shallow waters is incomplete; current maps used by BOEM to initiate environmental reviews do not include all features eligible for avoidance and may overestimate the extent of some features.

Knowledge of the location and size of PSBFs is critical for both effective and efficient environmental reviews performed by BOEM to ensure the protection of these sensitive habitats.

BOEM provided CSA with processed data products (e.g., bathymetry, backscatter, and/or amplitude maps, survey reports) from over 200 surveys from a prioritized list of OCS lease blocks to review.

CSA worked in close coordination with the BOEM project team to review survey data and identify and describe potential hard-bottom areas. The outcome of this project will be an annotated inventory of identified shallow water hard-bottom habitat features within selected OCS blocks in the GOM.

Gulf of Mexico Mesophotic and Deepwater Coral Assessment

CSA was contracted by the Gulf of Mexico Fishery Management Council to compile and synthesize information on deep-water coral and coral related habitats throughout the Gulf of Mexico (GoM) Exclusive Economic Zone. The project focused on mesophotic (30 to 150 m) and deep-water corals (deeper than 50 m) in federal waters of the GoM from 9 to 200 nautical miles offshore. The project included the production of a report, along with the development of a corresponding geodatabase and web-based dashboard that contained coral presence, coral density, coral species diversity, and benthic habitat composition of areas that support corals more broadly, such as deep-water banks, hard-bottom habitats, and isolated patch reefs. The design and content of the project was the result of continual coordination and consultation with Council staff throughout the completion of the scope of work.

This project was designed to address the Council’s request to compile and synthesize information on GoM coral and coral-related habitats in mesophotic and deep-water areas that were proposed but not included in Coral Amendment 9, as well as the identification and review of other habitats in the region that might warrant similar conservation and management measures.

Objectives of the project to meet the goals of the Council included site selection for the project’s focus; literature review of the selected deep reef coral areas and identify other ecologically important coral habitat that may benefit from management measures; data compilation of the most up-to-date information on selected sites as it relates to the presence of deep reef corals;

geodatabase construction for spatial data; design and conduction of a general ecological assessment of those areas where corals are identified as a conspicuous element of the bottom, providing, to the extent practical, a consistent level of detail for comparison across and among areas; and design and creation of a web-based dashboard with an interactive map displaying the shape/area and coordinates of the areas to be considered and associated information.

Large Submarine Canyons of the US OCS Atlas Submarine Canyons of the US EEZ Atlas

CSA provided the BOEM Office of Environmental Programs (OEP) with a single depository of maps and information on United States Outer Continental Shelf (OCS) submarine canyons to inform the preparation of environmental documents in 2019. CSA developed and implemented an objective system to inventory and delineate large submarine canyons on the OCS in the Atlantic, Pacific, and Arctic Oceans and the Gulf of Mexico. In 2022, CSA provided a companion Atlas that included by including mapping of additional medium to large submarine canyons and expanded to include additional areas in the US Exclusive Economic Zone (EEZ), including the Commonwealth of Puerto Rico, the Commonwealth of Northern Mariana Islands, and U.S. overseas territories and possessions.

To accomplish this, submarine canyons were delineated using a methodology consistent with terrestrial watershed mapping tools in Esri ArcGIS. A criteria-based algorithm generated spatial polygons used to calculate canyon slope, length, and depth. A concurrent literature review of existing published information and data provided a synopsis of the history, known archaeological sites, anthropogenic impacts, alternate names, geography, size, geology, biology, water quality (e.g., temperature, salinity, chemistry), currents, and any official designation (e.g., part of a National Marine Sanctuary) at each canyon. The literature citations were cataloged in an EndNote library and a synopsis there of was embedded in the geodatabase files. The information was simplified to create the notable facts seen in the Atlas.

The products associated with this project include the data deliverables, as well as a professionally designed and printed Atlas incorporating the Canyon maps and notable literature summaries.

Port of Miami Harbor Expansion Project – Coral And Seagrass

Mitigation

CSA provided marine environmental services for addressing potential coral and seagrass impacts as part of the environmental mitigation activities associated with the Miami Harbor Construction Dredging (Phase 3) Project. The Phase 3 construction dredging consisted of federally authorized improvements to Miami Harbor, including the deepening and widening of several features of the existing federal channel and berthing areas for the local sponsor, the Port of Miami. The project was conducted by the U.S. Army Corps of Engineers (USACE) and the Port of Miami.

As part of the project, CSA conducted natural resource surveys of coral habitats prior to the development and approval of a coral relocation plan;

conducted pre- and post-construction seagrass surveys in the ingress/egress routes surrounding the Julia Tuttle Mitigation Site (JTMS) and Lummus Island Turning Basin staging area; and created a seagrass transplantation plan for review and approval by the Client and the USACE.

To mitigate impacts, CSA relocated Acropora cervicornis (staghorn coral) colonies, a species listed as Threatened and protected under the Endangered Species Act of 1973, and non-Acropora hard coral colonies to a hardbottom reef south of the Miami Harbor Chanel entrance and a newly constructed artificial (mitigation) reef created for the project. In accordance with the National Marine Fisheries Service’s (NMFS’) Biological Opinion, CSA also collected and transferred staghorn coral fragments to the University of Miami Rosenstiel School of Marine and Atmospheric Science for out-growing in their permitted Acropora nursery to help achieve recovery goals of the species via future out-planting to a natural reef system. An initial post-relocation survey of the coral colonies and found them to be living with no consequential decline in health at the time. Long-term monitoring is being conducted by the local sponsor.

In addition, CSA harvested seagrass from an approved donor area and transplanted over 115,000 seagrass plants into the 17-acre JTMS, a newly filled dredge hole north of the Julia Tuttle Causeway in Miami. A comprehensive evaluation of the entire planted area and all planting units was conducted and, despite frequent feeding by manatees on the planted seagrass, the percent survival was documented at 97.6%—much higher than the mandated 70% survival.

Great Lakes Dredge and Dock and CSA staff initiated the further preservation and protection of hardbottom community resources by detaching an additional 644 hard corals and octocorals, along with 50-barrel sponges (Xestospongia muta). The organisms were then reattached at either the mitigation reef or adjacent hard bottom areas or donated to the Patricia and Phillip Frost Museum of Science for education and display purposes in their coral reef exhibit.

Lima, Mike, and November Wharves Coral Translocation Project

Repairs are planned to upgrade and modernize Lima, Mike, and November Wharves within Inner Apra Harbor in accordance with Naval Base Guam (NBG) Apra Harbor ship repair and heavy weather mooring mission requirements. Following the U.S. Navy consultation with the National Marine Fisheries Service on potential impacts to essential fish habitat and endangered species that could be present within the wharves repair project area the Navy proposed to translocate 4,100 healthy coral colonies from the Wharf Repair Project Area to a recipient site located on top of Mound 9 in Outer Apra Harbor.

The objective of the Lima, Mike, and November Wharves Coral Translocation Project was to 1) delineate and stabilize an ~400 m2 coral habitat area on the top of Mound 9 and 2) collect and translocate 4,100 healthy coral colonies from the wharf faces and adjacent seafloor to the delineated rehabilitation area.

Existing loose coral colonies present at the site were removed and cached immediately outside the boundary of the rehabilitation footprint.

Anthropogenic debris from within and immediately surrounding the rehabilitation site were collected and removed from the site. Limestone boulders (200) measuring approximately 0.6 to 1.2 m in diameter were then loaded onto a barge, transported to the site, and individually placed in four discrete, roughly 10- to 11-m diameter clusters within the rehabilitation footprint.

Coral colonies on the wharf faces and immediately adjacent seafloor were carefully removed using hammers and chisels and placed in metal-frame racks suspended just below the surface with large lift bags. The racks of corals were towed to the rehabilitation site at Mound 9 and then lowered to the bottom where the corals were temporarily cached before reattachment.

All transferred corals were identified to the lowest possible taxonomic level within the allowable timeframe and censused by size class (>5 to 10 cm, >10 to 20 cm, >20 to 40 cm, and >40 to 80 cm) prior to attachment. A total of approximately 4,570 corals representing at least 31 species were removed from the wharf faces and adjacent seafloor and transported and attached to the boulders and to concrete-reinforcement rod-rock rubble structures using a Portland cement mixture. In addition, ~50 corals of opportunity that had been temporarily removed from the Mound 9 site footprint prior to boulder placement in October 2020 were also reattached at the site. The introduction of the coral colonies provided an estimated additional >200 m2 of surface area to the rehabilitation site, in addition to the nearly 700 m2 of boulder surface area.
