(b) Topographic Features Map The activities proposed in this plan are in water depths less than 305 meters (1000 feet) of a topographic “No Activity Zone”; therefore, no map(s) are required per NTL No. 2009-G39, " Biologically Sensitive Underwater Features and Areas." (c) Topographic Features Statement The activities proposed under this plan will be conducted outside all Topographic Feature Protective Zones; therefore, shunting of drill cuttings and drilling fluids is not required per NTL No. 2009-G39, "Biologically Sensitive Underwater Features and Areas." (d) Live Bottom (Pinnacle Trend) Map The activities proposed in this plan are not affected by a live bottom (Pinnacle Trend) stipulation. (e) Live Bottom (Low Relief) Map The activities proposed in this plan are not affected by a live bottom (low relief) stipulation. (f) Potentially Sensitive Biological Features ECOP does not propose bottom-disturbing activities within 30 meters (100 feet) of potentially sensitive biological features; therefore, the map described in NTL No. 2009-G39 “Biologically Sensitive Underwater Features and Areas” is not required. (g) ROV Monitoring Survey Plan This information is no longer required. (h) Threatened and Endangered Species Information Congress passed the Endangered Species Act (ESA) on December 28, 1973, recognizing that the natural heritage of the United States was of “esthetic, ecological, educational, recreational, and scientific value to our Nation and its people.” It was understood that, without protection, many of our nation’s living resources would become extinct. The purpose of the ESA is to conserve threatened and endangered species and their ecosystems. There are more than 1,900 species listed under the ESA. A species is considered endangered if it is in danger of extinction throughout all or a significant portion of its range. A species is considered threatened if it is likely to become endangered in the future. The Interior Department's U.S. Fish and Wildlife Service (USFWS) and the Commerce Department's National Marine Fisheries Service (NMFS) share responsibility for implementing the ESA. The USFWS has primary responsibility for terrestrial and freshwater organisms, while the responsibilities of NMFS for marine species.

1. Designated Topographic Features The topographic features of the Central Gulf provide habitat for coral reef community organisms. Since 1973 stipulations have been made a part of leases on or near these biotic communities so that impacts from nearby oil and gas activities were mitigated to the greatest extent possible. This stipulation does not prevent the recovery of oil and gas resources but serves to protect valuable and sensitive biological resources. There are no IPFs (including effluents, physical disturbances to the seafloor, and accidents) from the proposed activities in East Cameron Area Blocks 71/72 that could cause impacts to topographic features. The activities proposed in this plan will be covered by our regional OSRP. 2. Pinnacle Trend Area Live Bottoms A small portion of the Central Planning Area and the Eastern Gulf of Mexico OCS planning areas include portions of approximately 70 lease blocks that have been classified as being within the “pinnacle trend” area. The Department of the Interior, Bureau of Ocean Energy Management is the agency with jurisdiction over these leases. The term “live bottom” is used to refer to the biological assemblages attached to hard substrates found interspersed between sand and mud bottoms of the continental shelf. These assemblages often consist of colorful sponges, corals, sea whips and sea fans rising from the benthic environment. Some of these features have extensive vertical relief rising far into the water column and serving as a reefal habitat for numerous commercially and recreationally important fish species. A special “Live Bottom (Pinnacle Trend) Stipulation” is assigned to leases in those blocks intended to protect the pinnacle trend and associated hard-bottom communities from damage and, at the same time, provide for recovery of potential oil and gas resources. This stipulation was not invoked with the issuance of these leases. The activities proposed in this plan will be covered by our regional OSRP.

3. Eastern Gulf Live Bottoms A small portion of the Central Planning Area and the Eastern Gulf of Mexico OCS planning areas include portions of approximately 70 lease blocks that have been classified as being within the “pinnacle trend” area. The Department of the Interior, Bureau of Ocean Energy Management is the agency with jurisdiction over these leases. The term “live bottom” is used to refer to the biological assemblages attached to hard substrates found interspersed between sand and mud bottoms of the continental shelf. These assemblages often consist of colorful sponges, corals, sea whips and sea fans rising from the benthic environment. Some of these features have extensive vertical relief rising far into the water column and serving as a reefal habitat for numerous commercially and recreationally important fish species. A special “Live Bottom (Pinnacle Trend) Stipulation” is assigned to leases in those blocks intended to protect the pinnacle trend and associated hard-bottom communities from damage and, at the same time, provide for recovery of potential oil and gas resources. This stipulation was not invoked with the issuance of these leases. There are no IPFs from the proposed activities in East Cameron Area Blocks 71/72 that could cause impacts to Eastern Gulf live bottoms. The site-specific offshore location of the proposed activity is over 100 miles from the eastern gulf live bottoms. The activities proposed in this plan will be covered by our regional OSRP. 4. Benthic Communities There are no IPFs from the proposed activities in East Cameron Area Blocks 71/72 that could cause impacts to Benthic Communities. Chemosynthetic biologic communities that lie in water depths in excess of 300 meters (984 feet) are of concern for environmental protection measures. The water depth at the proposed location is approximately 52 feet. 5. Water Quality Effluents, physical disturbances to the seafloor and accidents from the proposed activities in East Cameron Area Blocks 71/72 could potentially cause impacts to water quality. Routine impact-producing factors that could result in water quality degradation from offshore OCS oil and gas operations include rig / anchor emplacement, platform and pipeline installation and removal, and the discharge of operational wastes. The major discharges from offshore oil and gas exploration and production activities include produced water, drilling fluids and cuttings, ballast water, and uncontaminated seawater. Minor discharges from the offshore oil and gas industry include drilling-waste chemicals, fracturing and acidifying fluids, and well completion and workover fluids; and from production operations, deck drainage, and miscellaneous well fluids (cement, BOP fluid); and other sanitary and domestic wastes, gas and oil processing wastes, and miscellaneous discharges. Since all discharges will be made in accordance with a general National Pollutant Discharge Elimination System (NPDES) permit issued by U.S. Environmental Protection Agency (USEPA), operational discharges are not expected to cause significant adverse impacts to water quality. Additionally, an analysis of the best available information from the National Marine Fisheries Service Endangered Species Act (ESA) Section 7 Biological Opinion on the Federally Regulated Oil and Gas Program Activities in the Gulf of Mexico (NMFS, 2020) concludes that exposures to toxicants in discharges from oil and gas activities are not likely to adversely affect ESA-listed species (i.e. to include ESA-listed fish, Giant manta rays, Gulf sturgeon, Oceanic whitetip shark).

Offshore accidents, such as blowouts and spills could also occur and have the potential to alter offshore water quality. Sediment disturbance is expected to result in minor, localized, temporary increases in water-column turbidity in offshore waters. Given the low frequency of blowouts, minimum impacts on water quality due to re-suspension of sediments are expected. Oil spills related to the proposed action are assumed to be mostly very small events (and for spills greater than 50 bbl) to occur very infrequently. It is unlikely that an accidental oil spill would occur from the proposed activities. If a spill were to occur, the dissolved components and small oil droplets would temporarily affect the water quality of marine waters. Dispersion by currents and microbial degradation would remove the oil from the water column or dilute the constituents to background levels. The activities proposed in this plan will be covered by our Regional OSRP. 6. Fisheries Effects on commercial fisheries from activities associated with this plan could come from emplacement of production platform(s), underwater OCS obstructions, oil spills, subsurface blowouts, pipeline installation and offshore discharges of drilling mud and produced waters (See Section 5, Water Quality above). An accidental oil spill that may occur as a result of the proposed action has the potential to cause some detrimental effects to fisheries. However, it is unlikely that an accidental surface or subsurface oil spill would occur from the proposed activities. If a spill were to occur in open waters of the OCS proximate to mobile adult finfish or shellfish, the effects would likely be sublethal and the extent of damage would be reduced to the capability of adult fish and shellfish to avoid a spill, to metabolize Hydrocarbons, and to excrete both metabolites and parent compounds. The effect of oil spills on fisheries is expected to cause less than 1 percent decrease in commercial populations or in commercial fishing. At the expected level of effect, the resultant influence on Central Gulf fisheries is negligible and will be indistinguishable from natural population variations. The activities proposed in this plan will be covered by our regional OSRP. Drilling mud discharges contain chemicals toxic to marine fishes; however, this is only at concentrations 4 or 5 orders of magnitude higher than those found more than a few meters from the discharge point. Offshore discharges of drilling muds will dilute to background levels within 1000 meters of the discharge point and have a negligible effect on Central Gulf fisheries. Additionally, an analysis of the best available information from the National Marine Fisheries Service Endangered Species Act (ESA) Section 7 Biological Opinion on the Federally Regulated Oil and Gas Program Activities in the Gulf of Mexico (NMFS, 2020) concludes that exposures to toxicants in discharges from oil and gas activities are not likely to adversely affect ESA-listed species (i.e. to include ESA-listed fish, Giant manta rays, Gulf sturgeon, Oceanic whitetip shark). There are no other IPFs (including emissions and wastes sent to shore for disposal) from the proposed activities which could cause impacts to fisheries.

7. Marine Mammals Marine mammals may be adversely impacted by several IPFs (including vessel traffic, subsurface noise, accidental oil spills, and loss of trash and debris), all of which could occur due to the proposed action in East Cameron Area Blocks 71/72. Chronic and sporadic sublethal effects could occur that may stress and / or weaken individuals of a local group or population and make them more susceptible to infection from natural or anthropogenic sources. Few lethal effects are expected from oil spills, chance collisions with service vessels and ingestion of plastic material. Oil spills of any size are estimated to be periodic events that may contact cetaceans. Disturbance (e.g., subsurface noise) may stress animals, weaken their immune systems, and make them more vulnerable to parasites and diseases that normally would not be fatal. The net result of any disturbance would depend on the size and percentage of the population affected, ecological importance of the disturbed area, environmental and biological parameters that influence an animal’s sensitivity to disturbance and stress, and the accommodation time in response to prolonged disturbance (Geraci and St. Aubin, 1980). Collisions between cetaceans and ships could cause serious injury or death (Laist et al., 2001). Sperm whales are one of 11 whale species that are hit commonly by ships (Laist et al., 2001). Collisions between OCS vessels and cetaceans within the project area are expected to be unusual events. The activities proposed in this plan will be covered by our Regional OSRP. ECOP and its personnel and subcontractors, while undertaking activities authorized under these leases, must implement and comply with the most current measures set forth in the following documents, to protect or minimize any of the species listed in the Endangered Species Act (ESA):
• Appendices A, B, C and J to the NMFS 2020 Biological Opinion on the Federally Regulated Oil and Gas Program Activities in the Gulf of Mexico issued on March 13, 2020.
Other guidance documents utilized and issued by the BOEM include:

• BOEM NTL No. 2016-G01 (Vessel Strike Avoidance and Injured/Dead Protected Species Reporting)
• BOEM NTL No. 2016-G02 (Implementation of Seismic Survey Mitigation Measures and
Protected Species Observer Program) There are no other IPFs (including physical disturbances to the seafloor and wastes sent to shore) from the proposed activities which could impact marine mammals.

8. Sea Turtles IPFs that could impact sea turtles include vessel traffic, subsurface noise, trash and debris, and accidental oil spills. Small numbers of turtles could be killed or injured by chance collision with service vessels or by eating indigestible trash, particularly plastic items, accidentally lost from drill rigs, production facilities, and service vessels. Drilling rigs and project vessels produce subsurface noise that could disrupt normal behavior patterns and create some stress potentially making sea turtles more susceptible to disease. Oil spills and oil-spill-response activities are potential threats that could have lethal effects on turtles. Contact with oil, consumption of oil particles, and oil-contaminated prey could seriously affect individual sea turtles. Oil-spill-response planning and the habitat protection requirements of the Oil Pollution Act of 1990 should mitigate these threats. Most OCS-related impacts on sea turtles are expected to be sublethal. Chronic sublethal effects (e.g., stress) resulting in persistent physiological or behavioral changes and / or avoidance of affected areas could cause declines in survival or productivity, resulting in gradual population declines. The activities proposed in this plan will be covered by our Regional OSRP. ECOP and its personnel and subcontractors, while undertaking activities authorized under these leases, must implement and comply with the most current measures set forth in the following documents, to protect or minimize any of the species listed in the Endangered Species Act (ESA):
• Appendices A, B, C and J to the NMFS 2020 Biological Opinion on the Federally Regulated Oil and Gas Program Activities in the Gulf of Mexico issued on March 13, 2020.

9. Air Quality The proposed development activities are located 19 miles from the nearest Louisiana shoreline. Emissions of pollutants into the atmosphere from the development operations proposed are not expected to have significant impacts on onshore air quality because of the prevailing atmospheric conditions, emission heights, emission rates, and the distance of these emissions from the coastline. The Projected Air Quality Emissions Report indicates that the BOEM exemption level will not be exceeded during the development operations proposed in the plan. 10. Shipwreck Sites (Known or Potential) IPFs that could cause impacts to known or potential shipwreck sites from the proposed activities in East Cameron Area Blocks 71/72 include physical disturbances to the seafloor such as rig emplacement. A current review by Gulf Ocean Services of existing historical hazard and archaeological surveys performed on Lease OCS00184 did not highlight any obstructions or shipwrecks near the proposed well site. Analyses of available shipwreck sources indicate that no shipwrecks have been reported within the survey area. No sonar targets, magnetic anomalies, or other features on the geophysical data were recorded which were interpreted as possible shipwrecks within 1,000 feet of the proposed well location. However, in the event items of significant cultural resource potential are discovered during the proposed operations, ECOP will immediately halt all operations and notify the appropriate department at the BOEM for further evaluation and assistance. 11. Prehistoric Archaeological Sites IPFs that could cause impacts to known or potential prehistoric archaeological sites from the proposed activities include physical disturbances to the seafloor such as rig emplacement. A current review by Gulf Ocean Services of existing historical hazard and archaeological surveys performed on Lease OCS00184 did not identify any features of cultural significance near the proposed well site. No sonar targets, magnetic anomalies, or other features on the geophysical data were recorded which were interpreted as possible high probability areas for prehistoric habitation within 1,000 feet of the proposed well location. However, in the event items of significant cultural resource potential are discovered during the proposed operations, ECOP will immediately halt all operations and notify the appropriate department at the BOEM for further evaluation and assistance.

Vicinity of Offshore Location:
1. Essential Fish Habitat IPFs that could impact essential fish habitats as a result of the proposed operations in East Cameron Area Blocks 71/72 include emissions, effluents and accidents. The major effluent discharges from offshore oil and gas exploration and production activities include produced water, drilling fluids and cuttings, ballast water, and uncontaminated seawater (see Section 5, Water Quality, above). Minor discharges from the offshore oil and gas industry include drilling-waste chemicals, fracturing and acidifying fluids, and well completion and workover fluids; and from production operations, deck drainage, and miscellaneous well fluids (cement, BOP fluid); and other sanitary and domestic wastes, gas and oil processing wastes, and miscellaneous discharges.
Produced water will not be discharged during this operation. The activities proposed in this plan will be covered by our regional OSRP. There are no other IPFs (including physical disturbances or wastes sent to shore) from the proposed activities which could cause impacts to essential fish habitat. 2. Marine and Pelagic Birds IPFs that could impact marine and pelagic birds as a result of the proposed operations in East Cameron Area Blocks 71/72 include emissions, accidents and discarded trash and debris. Emissions of pollutant into the atmosphere from the activities associated with the proposed operations in this plan are not projected to have significant impacts on air quality that could harm marine and pelagic birds because of the prevailing atmospheric conditions, emission heights, emission rates and pollutant concentrations. An accidental oil spill that may occur as a result of the proposed action has the potential to cause some detrimental effects on marine and pelagic birds. Some physical oiling could occur during dives, as well as secondary toxic effects through the uptake of prey. However, it is unlikely that an accidental surface or subsurface oil spill would occur from the proposed activities. ECOP and its personnel and subcontractors, while undertaking activities authorized under these leases, must implement, and comply with the most current measures set forth in the following documents:
• Appendix B to the NMFS 2020 Biological Opinion on the Federally Regulated Oil and Gas Program Activities in the Gulf of Mexico issued on March 13, 2020.
Other guidance documents utilized and issued by the BOEM include:
• BSEE NTL No. 2015-G03 (Marine Trash and Debris Awareness and Elimination) The activities proposed in this plan will be covered by our Regional OSRP. There are no other IPFs (including effluents and physical disturbances to the seafloor) from the proposed activities which could cause impacts to marine and pelagic birds.

3. Public Health and Safety Due to Accidents There are no IPFs (including an accidental H2S releases) from the proposed activities that could cause impacts to public health and safety. Further, in accordance with 30 CFR 250.490(c) and NTL’s 2009-G27 and 2008-G04 we have submitted sufficient information to justify our request that the area of our proposed activities be classified by BOEM as H2S absent.
Coastal and Onshore: 1. Beaches Primary IPFs associated with offshore oil and gas exploration and development, and most widely recognized as major threats to the enjoyment and use of recreational beaches, are oil spills (accidents) and marine trash and debris. The operations proposed in this plan are not projected to have significant impacts on coastal beaches. An accidental oil spill that may occur as a result of the proposed action has the potential to cause some detrimental effects to beaches, however, it is unlikely that an accidental surface or subsurface oil spill would occur from the proposed development activities in East Cameron Area Blocks 71/72. The level of response to a spill will be based on volume, weather, and the characteristics of the product spilled. ECOP’s objectives for spill response are to ensure the safety of citizens and response personnel; control the source of the spill, have a coordinated response effort; maximize the protection of environmental sensitive areas; contain, recover and remove as much of the spill product as possible; recover and rehabilitate injured wildlife; minimize economic impacts; and keep the general public informed of the response activities.
The activities proposed in this plan will be covered by our regional OSRP. ECOP and its personnel and subcontractors, while undertaking activities authorized under these leases, must implement, and comply with the most current measures set forth in the following documents:

2. Wetlands According to the U.S. Department of the Interior ((Dahl, 1990); Henfer et al., 1994), during the mid-1980’s, 4.4 percent of Texas (3,083,860 ha) (Henfer et al., 1994), 28 percent of Louisiana (3,557,520 ha), 14 percent of Mississippi (17,678,730 ha) and 8 percent of Alabama (1,073,655 ha) were considered wetlands. More recent information indicates recent land change as a result of Hurricanes Katrina and Rita. The most notable was the 217-mi² of Louisiana’s coastal lands that were transformed to water after Hurricanes Katrina and Rita (Barras, 2006). The primary IPF associated with offshore oil and gas exploration and development, and most widely recognized as major threats to the wetlands are oil spills (accidents) and marine trash and debris. The operations proposed in this plan are not projected to have significant impacts on wetlands. ECOP and its personnel and subcontractors, while undertaking activities authorized under these leases, must implement, and comply with the most current measures set forth in the following documents:
• Appendix B to the NMFS 2020 Biological Opinion on the Federally Regulated Oil and Gas Program Activities in the Gulf of Mexico issued on March 13, 2020.

The activities proposed in this plan will be covered by our regional OSRP. 3. Shore Birds and Coastal Nesting Birds The primary IPF associated with offshore oil and gas exploration and development, and most widely recognized as a major threat to the shore birds and coastal nesting birds is oil spills (accidents) and marine trash and debris. The operations proposed in this plan are not projected to have significant impacts on shore birds and coastal nesting birds. An accidental oil spill that may occur as a result of the proposed action has the potential to cause some detrimental effects to shore birds and coastal nesting birds, however, it is unlikely that an accidental surface or subsurface oil spill would occur from the proposed activities in East Cameron Area Blocks 71/72. The level of response to a spill will be based on volume, weather, and the characteristics of the product spilled.

Other Environmental Resources Identified: 1. Bryde’s Whale
Gulf of Mexico Bryde's whales are members of the baleen whale family and a subspecies of the Bryde’s whale. With likely less than 100 individuals remaining, Gulf of Mexico Bryde’s whales are one of the most endangered whales in the world. Recovery of the species is dependent upon the protection of each remaining whale. The Gulf of Mexico Bryde’s whale has been consistently located in the northeastern Gulf of Mexico, along the continental shelf break between 100- and 400-meters depth. They are the only resident baleen whale in the Gulf of Mexico and are distinct from Bryde’s whales worldwide. The most significant threats facing Gulf of Mexico Bryde’s whales are energy exploration and development, oil spills and responses, vessel strikes, ocean noise, and entanglement in fishing gear. The Gulf of Mexico Bryde’s whale’s small population size and limited distribution increase their vulnerability. All Bryde’s whales are protected under the Marine Mammal Protection Act, including the Gulf of Mexico subspecies. In 2019, NOAA listed the Gulf of Mexico Bryde’s whale as endangered under the Endangered Species Act. Based on the location of the proposed activities in this Plan, there are no other IPFs (including emissions, effluents, physical disturbances to the seafloor, and wastes sent to shore) from the proposed activities which could cause impacts to the Bryde’s whales.

2. Gulf Sturgeon The Gulf sturgeon is a sub-species of the Atlantic sturgeon that can be found from Lake Pontchartrain and the Pearl River system in Louisiana and Mississippi to the Suwannee River in Florida. Hatched in the freshwater of rivers, Gulf sturgeon head out to sea as juveniles, and return to the rivers of their birth to spawn (lay eggs) when they reach adulthood. In the fall, movement from rivers into estuaries and associated bays begins in September and continues through November. Most subadult and adult Gulf sturgeon spend the cool winter months (October/November to March/ April) in bays, estuaries, and the nearshore Gulf of Mexico. Tagged fish have been found in well-oxygenated shallow water areas that support burrowing macro invertebrates. These areas may include shallow shoals (5 to 7 feet), deep holes near passes, unvegetated sand habitats such as sandbars, and intertidal and subtidal energy zones. Pollution and contamination from industrial, agricultural, and municipal activities is believed to cause a variety of physical, behavioral, and physiological impacts to sturgeon worldwide. In 1991, Gulf sturgeon were listed as threatened under the Endangered Species Act after their population was greatly reduced or eliminated throughout much of their range because of overfishing, dam construction, and habitat degradation. NOAA Fisheries and the U.S. Fish and Wildlife Service jointly manage and protect Gulf sturgeon. Based on the location of the proposed activities in this Plan, there are no other IPFs (including emissions, effluents, physical disturbances to the seafloor, and wastes sent to shore) from the proposed activities which could cause impacts to the Gulf sturgeon.
3. Giant Manta Ray
The giant manta ray is found worldwide in tropical, subtropical, and temperate bodies of water and is commonly found offshore, in oceanic waters, and near productive coastlines. As such, giant manta rays can be found in cool water, as low as 19°C, although temperature preference appears to vary by region. For example, off the U.S. East Coast, giant manta rays are commonly found in waters from 19 to 22°C, whereas those off the Yucatan peninsula and Indonesia are commonly found in waters between 25 to 30°C. The species has also been observed in estuarine waters near oceanic inlets, with use of these waters as potential nursery grounds. Based on the location of the proposed activities in this Plan, there are no other IPFs (including emissions, effluents, physical disturbances to the seafloor, and wastes sent to shore) from the proposed activities which could cause impacts to the giant manta ray.
4. Oceanic Whitetip Shark
The oceanic whitetip shark is found throughout the world in tropical and sub-tropical waters. It is a pelagic species, generally remaining offshore in the open ocean, on the outer continental shelf, or around oceanic islands in water depths greater than 600 feet. They live from the surface of the water to at least 498 feet deep. Oceanic whitetip sharks have a strong preference for the surface mixed layer in warm waters above 20°C and are therefore a surface-dwelling shark. The primary threat to the oceanic whitetip shark is incidental bycatch in commercial fisheries. Because of their preferred distribution in warm, tropical waters, and their tendency to remain at the surface, oceanic whitetip sharks have high encounter and mortality rates in fisheries throughout their range Based on the location of the proposed activities in this Plan, there are no other IPFs (including emissions, effluents, physical disturbances to the seafloor, and wastes sent to shore) from the proposed activities which could cause impacts to the oceanic whitetip shark.

5. Smalltooth Sawfish
Smalltooth sawfish live in tropical seas and estuaries (semi-enclosed areas where rivers meet the sea) of the Atlantic Ocean. They are most at home in shallow, coastal waters, and sometimes enter the lower reaches of freshwater river systems. There are few data about historical Smalltooth sawfish numbers. Smalltooth sawfish were once found in the Gulf of Mexico from Texas to Florida and along the East Coast from Florida to North Carolina. Their distribution has decreased greatly in U.S. waters over the past century, and today, the species is only found off the coast of Florida. Based on the location of the proposed activities in this Plan, there are no other IPFs (including emissions, effluents, physical disturbances to the seafloor, and wastes sent to shore) from the proposed activities which could cause impacts to the oceanic Smalltooth sawfish.
6. Nassau Grouper
The Nassau grouper is a reef fish. These large fish are associated with hard structure such as reefs (both natural and artificial), rocks, and ledges. They are late-maturing, long-lived, top-level predators found in southern coastal Florida, the Florida Keys, Bermuda, the Yucatan, and the Caribbean Sea. As juveniles they are found in nearshore shallow waters in macroalgal and seagrass habitats. They shift deeper as they grow, to predominantly reef habitat (forereef and reef crest). Nassau grouper are mostly absent from the continental United States—except Florida, where larger juveniles and adults have been recorded. No larval Nassau grouper or juveniles smaller than 20 inches in length have been collected or observed in Florida waters. However, sampling along shoreline habitats of the Florida Keys—where smaller juveniles might be expected—has been limited to date. Based on the location of the proposed activities in this Plan, there are no other IPFs (including emissions, effluents, physical disturbances to the seafloor, and wastes sent to shore) from the proposed activities which could cause impacts to the Nassau grouper.
(d) Environmental Hazards The site-specific environmental conditions have been taken into account for the proposed activities under this plan. Being located in the Gulf of Mexico, all oil and gas exploratory and development operations may at some time experience hurricane force winds, tropical storm activity and unusual surge and sea currents. In accordance with requirements set forth in Title 33 CFR 146.140, an Emergency Evacuation Plan (EEP) is prepared and submitted to the appropriate USCG Marine Safety Office or Unit for review and ultimate approval. This plan provides descriptions to help define the type of storm based on the winds associated with it (i.e., major gulf storm, squall, tropical depression, tropical storm, gale warning, storm warning, hurricane, etc). Major hurricanes (storm having wind speeds in excess of 74 mph) in the Gulf normally form in the southern Gulf or Caribbean Sea. Tropical disturbances (storms having wind speeds greater than 40 mph but less than 74 mph) that originate near the facility do not provide much warning, but usually pass the rig or facility prior to attaining hurricane status. Each tropical disturbance will be evaluated on its own merit and the operations modified accordingly. No impacts are expected on the proposed activities from site-specific environmental conditions.

¹ There are two subspecies of West Indian manatee: the Florida manatee (T. m. latirostris), which ranges from the northern Gulf of Mexico to Virginia, and the Antillean manatee (T. m. manatus), which ranges from northern Mexico to eastern Brazil. Only the Florida manatee subspecies is likely to be found in the northern Gulf of Mexico. On 30 March 2017, the USFWS announced the West Indian manatee, including the Florida manatee subspecies, was reclassified as Threatened. ² The Gulf of Mexico DPS of Bryde’s whales are protected by the Marine Mammal Protection Act (MMPA). Per 84 FR 15446, NMFS determined the Gulf of Mexico Bryde’s whale warranted listing as Endangered under the Endangered Species Act (ESA). ³ The Blue, Fin, Humpback, Sei, North Atlantic Right and Bryde’s Whales are uncommon in the Gulf of Mexico and are unlikely to be present in the projected area.

SPILL RESPONSE DISCUSSION For the purpose of NEPA and Coastal Zone Management Act analysis, the largest spill volume originating from the proposed activity would be a well blowout during production operations, estimated to be 3,940 barrels of condensate with an API gravity of 48°. Land Segment and Resource Identification Trajectories of a spill and the probability of it impacting a land segment have been projected utilizing information in the BOEM Oil Spill Risk Analysis Model (OSRAM) for the Central and Western Gulf of Mexico available on the BOEM website. The results are shown in Figure 1. The BOEM OSRAM identifies the highest probability of impact to the shorelines of Cameron Parish, Louisiana. Cameron Parish includes the east side of Sabine Lake, Sabine National Wildlife Refuge, Calcasieu Lake, Lacassine National Wildlife Refuge (inland) and Grand Lake. Cameron Parish also includes the area along the coastline from Sabine Pass to Big Constance Lake in Rockefeller Wildlife Refuge. This region is composed of open public beaches, marshlands and swamps. It serves as a habitat for numerous birds, finfish and other animals, including several rare, threatened and endangered species. Response EC Offshore Properties, Inc. will make every effort to respond to the Worst Case Discharge as effectively as practicable. A description of the response equipment under contract to contain and recover the Worst Case Discharge is shown in Figure 2. Using the estimated chemical and physical characteristics of condensate, an ADIOS weathering model was run on a similar product from the ADIOS oil database. The results indicate 61% or approximately 2,403 barrels of condensate would be evaporated/dispersed within 24 hours, with approximately 1,537 barrels remaining.
Natural Weathering Data: EC 72, Well 006 Barrels of Oil WCD Volume 3,940 Less 61% natural evaporation/dispersion 2,403 Remaining volume 1,537
Figure 2 outlines equipment, personnel, materials and support vessels as well as temporary storage equipment available to respond to the worst case discharge. The volume accounts for the amount remaining after evaporation/dispersion at 24 hours. The list estimates individual times needed for procurement, load out, travel time to the site and deployment. Figure 2 also indicates how operations will be supported. EC Offshore Properties, Inc.’s Oil Spill Response Plan includes alternative response technologies such as dispersants. Strategies will be decided by Unified Command based on a safety analysis, the size of the spill, weather and potential impacts. Although unlikely, if aerial dispersants are

utilized, 8 sorties (9,600 gallons) from two of the DC-3 aircrafts and 4 sorties (8,000 gallons) from the Basler aircraft would provide a daily dispersant capability of 7,540 barrels. Slick containment boom and sorbent boom would be immediately called out and on-scene as soon as possible. Offshore response strategies may include collection of condensate with sorbent boom (inside hard boom), attempting to skim utilizing CGA spill response equipment, with a total derated skimming capacity of 122,055 barrels. Temporary storage associated with skimming equipment equals 4,498 barrels. If additional storage is needed, various storage barges with a total capacity 131,000 bbls may be mobilized and centrally located to provide temporary storage and minimize off-loading time. Safety is first priority. Air monitoring will be accomplished and operations deemed safe prior to any containment/skimming attempts. If the spill went unabated, shoreline impact in Cameron Parish, Louisiana would depend upon existing environmental conditions. Shoreline protection would include the use of CGA’s near shore and shallow water skimmers with a totaled derated skimming capacity of 34,874 barrels. Temporary storage associated with skimming equipment equals 903 barrels. If additional storage is needed, various storage barges with a total capacity 70,000 bbls may be mobilized and centrally located to provide temporary storage and minimize off-loading time. Onshore response may include the deployment of shoreline boom on beach areas, or protection and sorbent boom on vegetated areas. A Master Service Agreement with AMPOL will ensure access to 29,700 feet of 18” shoreline protection boom. Figure 2 outlines individual times needed for procurement, load out, travel time to the site and deployment. Strategies would be based upon surveillance and real time trajectories that depict areas of potential impact given actual sea and weather conditions. Applicable Area Contingency Plans (ACPs), Geographic Response Plans (GRPs), and Unified Command (UC) will be consulted to ensure that environmental and special economic resources are correctly identified and prioritized to ensure optimal protection. Shoreline protection strategies depict the protection response modes applicable for oil spill clean-up operations. As a secondary resource, the State of Louisiana Initial Oil Spill Response Plan will be consulted as appropriate to provide detailed shoreline protection strategies and describe necessary action to keep the oil spill from entering Louisiana’s coastal wetlands. The UC should take into consideration all appropriate items detailed in Tactics discussion of this Appendix. The UC and their personnel have the option to modify the deployment and operation of equipment to allow for a more effective response to site-specific circumstances. EC Offshore Properties, Inc.’s contract Incident Management Team has access to the applicable ACP(s) and GRP(s). Based on the anticipated worst case discharge scenario, EC Offshore Properties, Inc. can be onsite with contracted oil spill recovery equipment with adequate response capacity to contain and recover surface hydrocarbons, and prevent land impact, to the maximum extent practicable, within an estimated 48 hours (based on the equipment’s Effective Daily Recovery Capacity (EDRC)).

Initial Response Considerations Actual actions taken during an oil spill response will be based on many factors to include but not be limited to:
• Safety • Weather • Equipment and materials availability • Ocean currents and tides • Location of the spill • Product spilled • Amount spilled • Environmental risk assessments • Trajectory and product analysis • Well status, i.e., shut in or continual release
EC Offshore Properties, Inc. will take action to provide a safe, aggressive response to contain and recover as much of the spilled oil as quickly as it is safe to do so. In an effort to protect the environment, response actions will be designed to provide an “in-depth” protection strategy meant to recover as much oil as possible as far from environmentally sensitive areas as possible. Safety will take precedence over all other considerations during these operations. Coordination of response assets will be supervised by the designation of a SIMOPS group as necessary for close quarter vessel response activities. Most often, this group will be used during source control events that require a significant number of large vessels operating independently to complete a common objective, in close coordination and support of each other. This group must also monitor the subsurface activities of each vessel (ROV, dispersant application, well control support, etc.). The SIMOPS group leader reports to the Source Control Section Chief. In addition, these activities will be monitored by the Incident Management Team (IMT) and Unified Command via a structured Common Operating Picture (COP) established to track resource and slick movement in real time. Upon notification of a spill, the following actions will be taken:
• Information will be confirmed • An assessment will be made and initial objectives set • OSROs and appropriate agencies will be notified • ICS 201, Initial Report Form completed • Initial Safety plan will be written and published • Unified Command will be established
o Overall safety plan developed to reflect the operational situation and coordinated objectives
o Areas of responsibility established for Source Control and each surface operational site
o On-site command and control established

Dedicated off-shore skimming systems General
• Deployed to the highest concentration of oil • Assets deployed at safe distance from aerial dispersant and in-situ burn operations
CGA HOSS Barge
• Use in areas with heaviest oil concentrations • Consider for use in areas of known debris (seaweed, and other floating materials)
CGA 95’ Fast Response Vessels (FRVs)
• Designed to be a first vessel on scene • Capable of maintaining the initial Command and Control function for on water recovery
operations • 24 hour oil spill detection capability • Highly mobile and efficient skimming capability • Use as far off-shore as safely possible
CGA FRUs
• To the area of the thickest oil • Use as far off-shore as allowed • VOOs 140’ – 180’ in length • VOOs with minimum of 18’ x 38’ or 23’ x 50’ of optimum deck space • VOOs in shallow water should have a draft of <10 feet when fully loaded
T&T Koseq Skimming Systems • To the area of the thickest oil • Use as far off-shore as allowed • VOOs with a minimum of 2,000 bbls storage capacity • VOOs at least 200’ in length • VOOs with deck space of 100’ x 40’ to provide space for arms, tanks, and crane • VOOs for shallow water should be deck barges with a draft of <10 feet when fully loaded

Vessels of Opportunity (VOO) • Use EC Offshore Properties, Inc.’s contracted resources as applicable • Industry vessels are ideal for deployment of Vessel of Opportunity Skimming Systems
(VOSS) • Acquire additional resources as needed • Consider use of local assets, i.e. fishing and pleasure craft for ISB operations or boom
tending • Expect mission specific and safety training to be required • Plan with the US Coast Guard for vessel inspections • Place VOOs in Division or Groups as needed • Use organic on-board storage if appropriate • Maximize non-organic storage appropriate to vessel limitations • Decant as appropriate after approval to do so has been granted • Assign bulk storage barges to each Division/Group • Position bulk storage barges as close to skimming units as possible • Utilize large skimming vessel (e.g. barges) storage for smaller vessel offloading • Maximize skimming area (swath) to the optimum width given sea conditions and available
equipment • Maximize use of oleophilic skimmers in all operations, but especially offshore • Nearshore, use shallow water barges and shuttle to skimming units to minimize offloading
time • Plan and equip to use all offloading capabilities of the storage vessel to minimize
offloading time Adverse Weather Operations: In adverse weather, when seas are > 3 feet, the use of larger recovery and storage vessels, oleophilic skimmers, and large offshore boom will be maximized. KOSEQ Arm systems are built for rough conditions, and they should be used until their operational limit (9.8’ seas) is met. Safety will be the overriding factor in all operations and will cease at the order of the Unified Command, vessel captain, or in an emergency, ”stop work” may be directed by any crew member. Surface Oil Recovery Considerations and Tactics (Offshore and Near-shore Operations)
Maximization of skimmer-oil encounter rate
• Place barges in skimming task forces, groups, etc., to reduce recovered oil offloading time
• Place barges alongside skimming systems for immediate offloading of recovered oil when practicable
• Use two vessels, each with heavy sea boom, in an open-ended “V” configuration to funnel surface oil into a trailing skimming unit’s organic, V-shaped boom and skimmer (see page 7, CGA Equipment Guide Book and Tactic Manual (CGATM)
ATTACHMENT LPUBLIC INFORMATION COPY
7
• Use secondary vessels and heavy sea boom to widen boom swath beyond normal skimming system limits (see page 15, CGATM)
• Consider night-time operations, first considering safety issues • Utilize all available advanced technology systems ( IR, X-Band Radar, etc.) to determine
the location of, and move to, recoverable oil • Confirm the presence of recoverable oil prior to moving to a new location
Maximize skimmer system efficiency
• Place weir skimming systems in areas of calm seas and thick oil • Maximize the use of oleophilic skimming systems in heavier seas • Place less mobile, high EDRC skimming systems (e.g. HOSS Barge) in the largest
pockets of the heaviest oil • Maximize onboard recovered oil storage for vessels. • Obtain authorization for decanting of recovered water as soon as possible • Use smaller, more agile skimming systems to recover streamers of oil normally found
farther from the source. Place recovered oil barges nearby
Recovered Oil Storage • Smaller barges in larger quantities will increase flexibility for multi-location skimming
operations • Place barges in skimming task forces, groups, etc., to reduce recovered oil offloading
time • Procure and deploy the maximum number of portable tanks to support Vessel of
Opportunity Skimming Systems if onboard storage is not available • Maximize use of the organic recovered oil storage capacity of the skimming vessel
Command, Control, and Communications (C3)
• Publish, implement, and fully test an appropriate communications plan • Design an operational scheme, maintaining a manageable span of control • Designate and mark C3 vessels for easy aerial identification • Designate and employ C3 aircraft for task forces, groups, etc. • Use reconnaissance air craft and Rapid Response Teams (RAT) to confirm the presence
of recoverable oil

On Water Recovery Group When the first skimming vessel arrives on scene, a complete site assessment will be conducted before recovery operations begin. Once it is confirmed that the air monitoring readings for O2, LEL, H2S, CO, VOC, and Benzene are all within the permissible limits, oil recovery operations may begin. As skimming vessels arrive, they will be organized to work in areas that allow for the most efficient vessel operation and free vessel movement in the recovery of oil. Vessel groups will vary in structure as determined by the Operations Section of the Unified Command, but will generally consist, at a minimum, of the following dedicated assets:
• 3 to 5 – Offshore skimming vessels (recovery) • 1 – Tank barge (temporary storage) • 1 – Air asset (tactical direction) • 2 – Support vessels (crew/utility for supply) • 6 to 10 – Boom vessels (enhanced booming )
Example (Note: Actual organization of TFs will be dependent on several factors including, asset availability, weather, spilled oil migration, currents, etc.) The 95’ FRV Breton Island out of Venice arrives on scene and conducts an initial site assessment. Air monitoring levels are acceptable and no other visual threats have been observed. The area is cleared for safe skimming operations. The Breton Island assumes command and control (CoC) of on-water recovery operations until a dedicated non-skimming vessel arrives to relieve it of those duties. A second 95’ FRV arrives and begins recovery operations alongside the Breton Island. Several more vessels begin to arrive, including a third 95’ FRV out of Galveston, the HOSS Barge (High Volume Open Sea Skimming System) out of Harvey, a boom barge (CGA 300) with 25,000’ of 42” auto boom out of Leeville, and 9 Fast Response Units (FRUs) from the load-out location at C-Port in Port Fourchon. As these vessels set up and begin skimming, they are grouped into task forces (TFs) as directed by the Operations Section of the Unified Command located at the command post. Initial set-up and potential actions:
• A 1,000 meter safety zone has been established around the incident location for vessels involved in Source Control
• The HOSS Barge is positioned facing the incident location just outside of this safety zone or at the point where the freshest oil is reaching the surface
• The HOSS Barge engages its Oil Spill Detection (OSD) system to locate the heaviest oil and maintains that ability for 24-hour operations
ATTACHMENT LPUBLIC INFORMATION COPY
9
• The HOSS Barge deploys 1,320’ of 67” Sea Sentry boom on each side, creating a swath width of 800’
• The Breton Island and H.I. Rich skim nearby, utilizing the same OSD systems as the HOSS Barge to locate and recover oil
• Two FRUs join this group and it becomes TF1 • The remaining 7 FRUs are split into a 2 and 3 vessel task force numbered TF2 and TF3 • A 95’ FRV is placed in each TF • The boom barge (CGA 300) is positioned nearby and begins deploying auto boom in
sections between two utility vessels (1,000’ to 3,000’ of boom, depending on conditions) with chain-link gates in the middle to funnel oil to the skimmers
• The initial boom support vessels position in front of TF2 and TF3 • A 100,000+ barrel offshore tank barge is placed with each task force as necessary to
facilitate the immediate offload of skimming vessels The initial task forces (36 hours in) may be structured as follows: TF 1
• 1 – 95’ FRV • 1 – HOSS Barge with 3 tugs • 2 – FRUs • 1 – 100,000+ barrel tank barge and associated tug(s) • 1 – Dedicated air asset for tactical direction • 8 – 500’ sections of auto boom with gates • 8 – Boom-towing vessels • 2 – Support vessels (crew/utility)
TF 2
• 1 – 95’ FRV • 4 – FRUs • 1 – 100,000+ barrel tank barge and associated tug(s) • 1 – Dedicated air asset for tactical direction • 10 – 500’ sections of auto boom with gates • 10 – Boom-towing vessels • 2 – Support vessels (crew/utility)
TF 3
• 1 – 95’ FRV • 3 – FRUs • 1 – 100,000+ barrel tank barge and associated tug(s) • 1 – Dedicated air asset for tactical direction • 8 – 500’ sections of auto boom with gates • 8 – Boom-towing vessels • 2 – Support vessels (crew/utility)

Radio Tactical use of Vessels of Opportunity (VOO): EC Offshore Properties, Inc. will take all possible measures to maximize the oil-to-skimmer encounter rate of all skimming systems, to include VOOs, as discussed in this section. VOOs will normally be placed within an On-water recovery unit as shown in figures below. Skimming Operations: PIDVs are the preferred VOO skimming platform. OSROs are more versed in operating on these platforms and the vessels are generally large enough with crews more likely versed in spill response operations. They also have a greater possibility of having on-board storage capacity and the most likely vessels to be under contract, and therefore more readily available to the operator. These vessels would normally be assigned to an on-water recovery group/division (see figure below) and outfitted with a VOSS suited for their size and capabilities. Specific tactics used for skimming operations would be dependent upon many parameters which include, but are not limited to, safety concerns, weather, type VOSS on board, product being recovered, and area of oil coverage. Planners would deploy these assets with the objective of safely maximizing oil- to-skimmer encounter rate by taking actions to minimize non-skimming time and maximizing boom swath. Specific tactical configurations are shown in figures below.

The Fast Response Unit (FRU): A self-contained, skid based, skimming system that is deployed from the right side of a vessel of opportunity (VOO). An outrigger holds a 75’ long section of air inflatable boom in place that directs oil to an apex for recovery via a Foilex 250 weir skimmer. The outrigger creates roughly a 40’ swath width dependent on the VOO beam. The lip of the collection bowl on the skimmer is placed as close to the oil and water interface as possible to maximize oil recovery and minimize water retention. The skimmer then pumps all fluids recovered to the storage tank where it is allowed to settle, and with the approval of the Coast Guard, the water is decanted from the bottom of the tank back into the water ahead of the containment boom to be recycled through the system. Once the tank is full of as much pure recovered oil as possible it is offloaded to a storage barge for disposal in accordance with an approved disposal plan. A second 100 barrel storage tank can be added if the appropriate amount of deck space is available to use as secondary storage. Tactical Overview Mechanical Recovery – The FRU is designed to provide fast response skimming capability in the offshore and nearshore environment in a stationary or advancing mode. It provides a rated daily recovery capacity of 4,100 barrels. An additional boom reel with 440’ of offshore boom can be deployed along with the FRU, and a second support vessel for boom towing, to extend the swath width when attached to the end of the fixed boom. The range and sustainability offshore is dependent on the VOO that the unit is placed on, but generally these can stay offshore for extended periods. The FRU works well independently or assigned with other on-water recovery assets in a task force. In either case, it is most effective when a designated aircraft is assigned to provide tactical direction to ensure the best placement in recoverable oil. Maximum Sea Conditions – Under most circumstances the FRU can maintain standard oil spill recovery operations in 2’ to 4’ seas. Ultimately, the Coast Guard licensed Captain in charge of the VOO (with input from the CGAS Supervisor assigned) will be responsible to determine when the sea conditions have surpassed the vessel’s safe operating capabilities. Possible Task Force Configuration (Multiple VOOs can be deployed in a task force) 1 – VOO (100’ to 165’ Utility or Supply Vessel) 1 – Boom reel w/support vessel for towing 1 – Tank barge (offshore) for temporary storage 1 – Utility/Crewboat (supply) 1 – Designated spotter aircraft

The VOSS (yellow) is being deployed and connected to an out-rigged arm. This is suitable for collection in both large pockets of oil and for recovery of streaming oil. The oil-to-skimmer encounter rate is limited by the length of the arm. Skimming pace is < 1 knot.
Through the use of an additional VOO, and using extended sea boom, the swath of the VOSS is increased therefore maximizing the oil-to-skimmer encounter rate. Skimming pace is < 1 knot.

The Koseq Rigid Sweeping Arm: A skimming system deployed on a vessel of opportunity. It requires a large Offshore or Platform Supply Vessel (OSV/PSV), greater than 200’ with at least 100’ x 50’ of free deck space. On each side of the vessel, a 50’ long rigid framed Arm is deployed that consists of pontoon chambers to provide buoyancy, a smooth nylon face, and a hydraulically adjustable mounted weir skimmer. The Arm floats independently of the vessel and is attached by a tow bridle and a lead line. The movement of the vessel forward draws the rubber end seal of the arm against the hull to create a collection point for free oil directed to the weir by the Arm face. The collection weir is adjusted to keep the lip as close to the oil water interface as possible to maximize oil recovery while attempting to minimize excess water collection. A transfer pump (combination of positive displacement, screw type and centrifuge suited for highly viscous oils) pump the recovered liquid to portable tanks and/or dedicated fixed storage tanks onboard the vessel. After being allowed to sit and separate, with approval from the Coast Guard, the water can be decanted (pumped off) in front of the collection arm to be reprocessed through the system. Once full with as much pure recovered oil as possible, the oil is transferred to a temporary storage barge where it can be disposed of in accordance with an approved disposal plan. Tactical Overview Mechanical Recovery – Deployed on large vessels of opportunity (VOO) the Koseq Rigid Sweeping Arms are high volume surge capacity deployed to increase recovery capacity at the source of a large oil spill in the offshore and outer nearshore environment of the Gulf of Mexico. They are highly mobile and sustainable in rougher sea conditions than normal skimming vessels (9.8’ seas). The large Offshore Supply Vessels (OSV) required to deploy the Arms are able to remain on scene for extended periods, even when sea conditions pick up. Temporary storage on deck in portable tanks usually provides between 1,000 and 3,000 bbls. In most cases, the OSV will be able to pump 20% of its deadweight into the liquid mud tanks in accordance with the vessels Certificate of Inspection (COI). All storage can be offloaded utilizing the vessels liquid transfer system. Maximum Sea Conditions - Under most circumstances the larger OSVs are capable of remaining on scene well past the Skimming Arms maximum sea state of 9.8’. Ultimately it will be the decision of the VOO Captain, with input from the T&T Supervisor onboard, to determine when the sea conditions have exceeded the safe operating conditions of the vessel. Command and Control – The large OSVs in many cases have state of the art communication and electronic systems, as well as the accommodations to support the function of directing all skimming operations offshore and reporting back to the command post. Possible Task Force Configuration (Multiple Koseq VOOs can be deployed in a task force) 1 – > 200’ Offshore Supply Vessels (OSV) with set of Koseq Arms 2 to 4 portable storage tanks (500 bbl) 1 – Modular Crane Pedestal System set (MCPS) or 30 cherry picker (crane) for deployment 1 – Tank barge (offshore) for temporary storage 1 – Utility/Crewboat (supply) 1 – Designated spotter aircraft 4 – Personnel (4 T&T OSRO)

Scattered oil is “caught” by two VOO and collected at the apex of the towed sea boom. The oil moves thought a “gate” at that apex, forming a larger stream of oil which moves into the boom of the skimming vessel. Operations are paced at >1. A recovered oil barge stationed nearby to minimize time taken to offload recovered oil.
This is a depiction of the same operation as above but using KOSEQ Arms. In this configuration, the collecting boom speed dictates the operational pace at > 1 knot to minimize entrainment of the oil.

Clean Gulf Associates (CGA) Procedure for Accessing Member-Contracted and other Vessels of Opportunity (VOOs) for Spill Response
• CGA has procedures in place for CGA member companies to acquire vessels of opportunity (VOOs) from an existing CGA member’s contracted fleet or other sources for the deployment of CGA portable skimming equipment including Koseq Arms, Fast Response Units (FRUs) and any other portable skimming system(s) deemed appropriate for the response for a potential or actual oil spill, WCD oil spill or a Spill of National Significance (SONS).
• CGA uses Port Vision, a web-based vessel and terminal interface that empowers CGA to
track vessels through Automatic Identification System (AIS) and terminal activities using a Geographic Information System (GIS). It provides live AIS/GIS views of waterways showing current vessel positions, terminals, created vessel fleets, and points-of-interest. Through this system, CGA has the ability to get instant snapshots of the location and status of all vessels contracted to CGA members, day or night, from any web-enabled PC.

Near Shore Response Actions Timing
• Put near shore assets on standby and deployment in accordance with planning based on the actual situation, actual trajectories and oil budgets
• VOO identification and training in advance of spill nearing shoreline if possible • Outfitting of VOOs for specific missions • Deployment of assets based on actual movement of oil
Considerations
• Water depth, vessel draft • Shoreline gradient • State of the oil • Use of VOOs • Distance of surf zone from shoreline
Surveillance
• Provide trained observer to direct skimming operations • Continual surveillance of oil movement by remote sensing systems, aerial photography
and visual confirmation • Continual monitoring of vessel assets
Dispersant Use
• Generally will not be approved within 3 miles of shore or with less than 10 meters of water depth
• Approval would be at Regional Response Team level (Region 6) Dedicated Near Shore skimming systems
• FRVs • Egmopol and Marco SWS • Operate with aerial spotter directing systems to observed oil slicks
VOO
• Use EC Offshore Properties, Inc.’s contracted resources as applicable • Industry vessel are usually best for deployment of Vessel of Opportunity Skimming
Systems (VOSS) • Acquire additional resources as needed • Consider use of local assets, i.e. fishing and pleasure craft • Expect mission specific and safety training to be required • Plan with the US Coast Guard for vessel inspections • Operate with aerial spotter directing systems to oil patches

Shoreline Protection Operations Response Planning Considerations
• Review appropriate Area Contingency Plan(s) • Locate and review appropriate Geographic Response and Site Specific Plans • Refer to appropriate Environmentally Sensitive Area Maps • Capability for continual analysis of trajectories run periodically during the response • Environmental risk assessments (ERA) to determine priorities for area protection • Time to acquire personnel and equipment and their availability • Refer to the State of Louisiana Initial Oil Spill Response Plan, Deep Water Horizon,
dated 2 May 2010, as a secondary reference • Aerial surveillance of oil movement • Pre-impact beach cleaning and debris removal • Shoreline Cleanup Assessment Team (SCAT) operations and reporting procedures • Boom type, size and length requirements and availability • Possibility of need for In-situ burning in near shore areas • Current wildlife situation, especially status of migratory birds and endangered species in
the area • Check for Archeological sites and arrange assistance for the appropriate state agency
when planning operations the may impact these areas Placement of boom
• Position boom in accordance with the information gained from references listed above and based on the actual situation
• Determine areas of natural collection and develop booming strategies to move oil into those areas
• Assess timing of boom placement based on the most current trajectory analysis and the availability of each type of boom needed. Determine an overall booming priority and conduct booming operations accordingly. Consider:
o Trajectories o Weather forecast o Oil Impact forecast o Verified spill movement o Boom, manpower and vessel (shallow draft) availability o Near shore boom and support material, (stakes, anchors, line)
Beach Preparation - Considerations and Actions
• Use of a 10 mile go/no go line to determine timing of beach cleaning • SCAT reports and recommendations • Determination of archeological sites and gaining authority to enter • Monitoring of tide tables and weather to determine extent of high tides • Pre cleaning of beaches by moving waste above high tide lines to minimize waste • Determination of logistical requirements and arranging of waste removal and disposal

• Staging of equipment and housing of response personnel as close to the job site as possible to maximize on-site work time
• Boom tending, repair, replacement and security (use of local assets may be advantageous) • Constant awareness of weather and oil movement for resource re-deployment as
necessary • Earthen berms and shoreline protection boom may be considered to protect sensitive
inland areas • Requisitioning of earth moving equipment • Plan for efficient and safe use of personnel, ensuring:
o A continual supply of the proper Personal Protective Equipment o Heating or cooling areas when needed o Medical coverage o Command and control systems (i.e. communications) o Personnel accountability measures
• Remediation requirements, i.e., replacement of sands, rip rap, etc. • Availability of surface washing agents and associated protocol requirements for their use
(see National Contingency Plan Product Schedule for list of possible agents) • Discussions with all stakeholders, i.e., land owners, refuge/park managers, and others as
appropriate, covering the following: o Access to areas o Possible response measures and impact of property and ongoing operations o Determination of any specific safety concerns o Any special requirements or prohibitions o Area security requirements o Handling of waste o Remediation expectations o Vehicle traffic control o Domestic animal safety concerns o Wildlife or exotic game concerns/issues
Inland and Coastal Marsh Protection and Response Considerations and Actions
• All considered response methods will be weighed against the possible damage they may do to the marsh. Methods will be approved by the Unified Command only after discussions with local Stakeholder, as identified above.
o In-situ burn may be considered when marshes have been impacted • Passive clean up of marshes should considered and appropriate stocks of sorbent boom
and/or sweep obtained. • Response personnel must be briefed on methods to traverse the marsh, i.e.,
o use of appropriate vessel o use of temporary walkways or road ways
• Discuss and gain approval prior cutting or moving vessels through vegetation • Discuss use of vessels that may disturb wildlife, i.e, airboats • Safe movement of vessels through narrow cuts and blind curves

• Consider the possibility that no response in a marsh may be best • In the deployment of any response asset, actions will be taken to ensure the safest, most
efficient operations possible. This includes, but is not limited to: o Placement of recovered oil or waste storage as near to vessels or beach cleanup
crews as possible. o Planning for stockage of high use items for expeditious replacement o Housing of personnel as close to the work site as possible to minimize travel time o Use of shallow water craft o Use of communication systems appropriate ensure command and control of assets o Use of appropriate boom in areas that I can offer effective protection o Planning of waste collection and removal to maximize cleanup efficiency
• Consideration or on-site remediation of contaminated soils to minimize replacement operations and impact on the area

Decanting Strategy Recovered oil and water mixtures will typically separate into distinct phases when left in a quiescent state. When separation occurs, the relatively clean water phase can be siphoned or decanted back to the recovery point with minimal, if any, impact. Decanting therefore increases the effective on-site oil storage capacity and equipment operating time. FOSC/SOSC approval will be requested prior to decanting operations. This practice is routinely used for oil spill recovery. CGA Equipment Limitations The capability for any spill response equipment, whether a dedicated or portable system, to operate in differing weather conditions will be directly in relation to the capabilities of the vessel the system in placed on. Most importantly, however, the decision to operate will be based on the judgment of the Unified Command and/or the Captain of the vessel, who will ultimately have the final say in terminating operations. Skimming equipment listed below may have operational limits which exceed those safety thresholds. As was seen in the Deepwater Horizon (DWH) oil spill response, vessel skimming operations ceased when seas reached 5-6 feet and vessels were often recalled to port when those conditions were exceeded. Systems below are some of the most up-to-date systems available and were employed during the DWH spill.
Boom 3 foot seas, 20 knot winds Dispersants Winds more than 25 knots
Visibility less than 3 nautical miles Ceiling less than 1,000 feet.
FRU 8 foot seas HOSS Barge/OSRB 8 foot seas Koseq Arms 8 foot seas OSRV 4 foot seas

Environmental Conditions in the GOM Louisiana is situated between the easterly and westerly wind belts, and therefore, experiences westerly winds during the winter and easterly winds in the summer. Average wind speed is generally 14-15 mph along the coast. Wave heights average 4 and 5 feet. However, during hurricane season, Louisiana has recorded wave heights ranging from 40 to 50 feet high and winds reaching speeds of 100 mph. Because much of southern Louisiana lies below sea level, flooding is prominent. Surface water temperature ranges between 70 and 80˚F during the summer months. During the winter, the average temperature will range from 50 and 60˚F. The Atlantic and Gulf of Mexico hurricane season is officially from 1 June to 30 November. 97% of all tropical activity occurs within this window. The Atlantic basin shows a very peaked season from August through October, with 78% of the tropical storm days, 87% of the minor (Saffir-Simpson Scale categories 1 and 2) hurricane days, and 96% of the major (Saffir-Simpson categories 3, 4 and 5) hurricane days occurring then. Maximum activity is in early to mid September. Once in a few years there may be a hurricane occurring "out of season" - primarily in May or December. Globally, September is the most active month and May is the least active month.
