(C) Safety & pollution features :

LLOG will utilize a drillship, semi

- submersible moored rig or DP Semi

submersible rig for the proposed operations. A description of the drilling unit is

included on the OCS Plans Information Form. Rig specifications will be made part of the Application for Permit to Drill.

Safety features on the drilling unit will include well control, pollution prevention, and blowout prevention equipment as described in Title 30 CFR Part 250, Subparts C, D, E and G; and further clarified by BOEM’s Notices to Lessees, and currently policy making invoked by BOEM, EPA and USCG. Appropriate life rafts, life jackets, ring buoys, etc., will be maintained on the facility at all times.

Pollution prevention measures include installation of curbs, gutters, drip pans, and drains on the drilling deck areas to collect all contaminants and debris

### Anchor Pattern:

LLOG Exploration Offshore LLC has not as yet issued a specific anchor pattern to retain the
drilling rig. The anchor radius illustrated on Plats and Charts for the proposed Block MC707

- B well surface location is the ma ximum predicted radius of 7,000 ft. An anchor

- spread pattern
can be designed as an addendum to this report after t he drilling rig has been identified. The
anchor pattern will be designed to avoid any infrastructure and potentially sensitive seabed

habitats.

Bat hymetry
Water depth at the proposed MC707 -B well surface location is

- 1,567 ft below sea

- surface.
The seafloor deepens evenly to the ENE at 2.7 °.

Seabed Morphology, Faults and Sensitive Sessile Benthic Communities
The seabed within the radius of the proposed anchor pat tern deepens evenly to the ENE

.

The pr oposed well is locate d in an area of smooth seabed within a slight bathymetrical high

area

.

Ar eas considered to be potential sites for hosting sensitive sessile benthic communities are
located to the southwest of the proposed well location beyond the 2,000ft radius. Two
potential larger sites were identified, one to the WSW at 2,159ft from the propose location,

and the second to the SSW at 2,5 51ft. These must be avoided by at least 250ft by all
anchoring activities.

Tw o mud mounds are identified, one to the northea st and the other to the southwest of the
proposed well. These mud volcanoes must be avoided by all anchor activity.LLOG Exploration Offshore LLC Gardline Report 9946.01

- B Well Location



### Seabed faults occur to the southwest and the northwest of the 7,000ft radius. Avoidance of
the seabed fault scarps is r ecommended.

S ever al seabed drainage pathways traverse the anchor radius area . These should not affect

anchor positioning.

S everal pipelines and an existing well are located within the 7,000ft radius. The following are

### Anchor Pattern:

LLOG Exploration Offshore LLC has not as yet issued a specific anchor pattern to retain the
drilling rig. The anchor radius illustrated on Plats and Charts for the proposed Block MC707

- C well surface location is the ma ximum predicted radius of 7,000ft. An anchor

- spread pattern
can be designed as an addendum to this report after t he drilling rig has been identified. The
anchor pattern will be designed to avoid any infrastructure and potentially sensitive seabed

habitats.

B athymetry
Water depth at the proposed MC707 -C well surface location is

- 1,563 ft below sea

- surface.
The seafloor deepens evenly to the ENE at 1.9 °.

S eabed Morphology, Faults and Sensitive Sessile Benthic Communities
The seabed within the radius of the proposed anchor pat tern deepens evenly to the ENE

.

The p roposed well is locate d in an area of smooth seabed within a slight bathymetrical high

area

.

A reas considered to be potential sites for hosting sensitive sessile benthic communities are
located to the southwest of the proposed well location beyond the 2,000ft radius. Two

pot ential sites were identified, one to the WSW at 2,022ft from the propose d location, and the

second to the SSW at 2,450ft. These must be avoided by at least 250ft by all anchoring

activities.

T wo mud mounds are identified, one to the northeast and the other to the southwest of the
proposed well. These mud volcanoes must be avoided by all anchor activity.LLOG Exploration Offshore LLC Gardline Report TBA

INFORMATION REQUIREMENTS

A) Blowout scenario

The MC 707 prospect to be drilled to potential outlined in the Geological and Geophysical Information Section of this plan utilizing a typical subsea wellhead system, conductor, surface and intermediate casing strings from a pre

- existing wellbore and a M ODU rig with marine riser and a subsea BOP system. A hy drocarbon influx and a well control event occurr ing from the objective sand is modeled with no drill pipe or obstructions in the wellbore followed by a failure of the subsea BOP’s and loss of well control at the seabed. The simulated flow and worst case discharge (WCD) results for all wells are calculated and the highest WCD is used for this unrestricted blowout scenario.

B) Estimated flow rate of the potential blowout

E) Potential for the well to bridge over

Mechanical failure/collapse of the borehole in a blowout scenario is influenced by several factors including in

- situ stress, rock strength and fluid velocities at the sand face. Given the substantial fluidBLOWOUT SCENARIO

MC 707

2 velocities inherent in the WCD, and the scenario as defined where the formation is not supported by a cased and cemented wellbore, it is possible that the borehole may fall/collapse/bridge over within a span of a few days, significantly reducing the outflow of the rates. For this blowout scenario, no bridging is considered.

F) Likelihood for intervention to stop blowout

The likelihood of surface intervention to stop a blowout is based on some of the following equipm ent specific to potential MODU’s to be contracted for this well. It is reasonable to assume that the sooner you are able to respond to the initial blowout, the better likelihood there is to control and contain the event due to reduced pressures at the wel lhead

, less exposure of well fluids to erode and compromise the well control equipment, and less exposure of hydrocarbons to the surface to safeguard personnel and equipment in an emergency situ ation. This equipment includes:

• Secondary Acoustic BOP Contr ol System – typically fitted on DP MODU’s presently operating in the GOM. This system has the ability to communicate and function specific BOP controls from the surface in the event of a failure of the primary umbilical control system. This system typica lly can establish BOP controls from the surface acoustic system package on the rig or by deploying a second acoustic package from a separate vessel of opportunity. This system may not be included on all MODU’s such as 4 th generation moored rigs. This sys tem is typically configured to function the following:

- Blind / shear ram close

- Pipe ram close

- LMRP disconnect

• ROV Intervention BOP Control System – includes one or more ROV intervention panels mounted on the subsea BOP’s located on the seabed allows a ROV utilizing standard ROV stabs to access and function the specific BOP controls. These functions will be tested at the surface as part of the required BOP stump test and selectively at the seafloor to ensure proper functionality. These function include the following (at a minimum):

- Blind/shear ram close

- Pipe ram close

- LMRP disconnect

- WH disconnect

• Deadman / Autoshear function – typically fitted on DP MODU’s and but to be on all MODU’s operating in the GOM according to new requirements, this equipment allows for an automated pre

- programmed sequence of functions to close the casing shear rams and the blind/shear rams in the event of an inadvertent or emergency disconnect of the LMRP or loss of both hydraulic and electrical supply from the surface control system.

In the event that the intervention systems for the subsea BOP’s fail, LLOG will initiate call out of a secondary containment / surface intervention system supported by the Helix Well Containment Group (HWCG) of which LLOG is a member. This syste m incorporates a capping stack capable of being deployed from the back of a vessel of opportunity equipped with an ROV or from the Helix Q4000 DP MODU. Based on the potential integrity concerns of the well, a “cap and flow” system can be deployed which may include the Helix Producer 1 capable of handling up to 55,000 BOPD flowback. The vertical intervention work is contingent upon the condition of the blowing out well and what equipment is intact to access the wellbore for kill or containment operations. The available intervention equipment may also require modifications based on actual wellbore conditions. StandardBLOWOUT SCENARIO

Last Revised: 5/27/2014 Page 3 of 6

3 equipment is available through the Helix Deepwater Containment System to fit the wellhead and BOP stack profiles used for the drilling of th e above mentioned well.

G) Availability of rig to drill relief well , rig constraints and timing of rigs

LLOG currently has one deepwater MODU under contract (Noble Amos Runner moored semi). In the

event of a blowout scenario that does not involve loss or damage to the rig such as an inadvertent disconnect of the BOP’s, then the existing contracted rig may be available for drilling the relief well

and vertical intervention work . If the blowout scenario involves damage to the rig or loss of the BOP ’s and riser, a replacement rig or rigs will be required.

With the current activity level in the GOM, 25 to 35 deepwater MODU’S are potentially available to support the relief well drilling operations. Rig share and resource sharing agreements are in place

bet ween members of the Helix Well Containment Group. The ability to negotiate and contract an appropriate rig or rigs to drill relief wells is highly probable in a short period of time. If the rig or rigs are operating, the time to properly secure the well and mobe the rig to the relief well site location is

estimated to be about 14 to 21 days. Dynamically positioned (DP) MODU’s would be the preferred option due to the logistical advantage versus a moored MODU which may add complications due to the mooring spread.

VESSELS OF OPPORTUNITY

Based on the water depth restrictions for the proposed locations the following “Vessels of Opportunity” are presently available for utilization for intervention and containment and relief well operations. These may include service vessels and drilling rigs capable of working in the potential water depths and may include moored vessels and dynamically positioned vessels. The specific conditions of the intervention or relief well operations will dictate the “best fit” vessel to efficiently perform the desired results based on the blowout scenario. The list included below illustrates specific option that may vary according to the actual timing / availability at the time the vessels are needed.

H) Measures taken to enhance ability to prevent blowout

Pursuant to BOEM

- 2010

- 034 Final Interim Rules, measures to enhance the ability to prevent or

reduce the likelihood of a blowout are largely based on proper planning and communication, identification of potential hazards, training and experience of personnel, use of good oil field practices and proper equipment that is properly maintained and inspected f or executing drilling operations of the proposed well or wells to be drilled.BLOWOUT SCENARIO

4 When planning and designing the well, ample time is spent analyzing offset data, performing any needed earth modeling and identifying any potential drilling hazards or well specific conditions to

s afeguard the safety of the crews when well construction operations are underway. Once the design criteria and well design is established, the well design is modeled for the lifecycle of the wellbore to ensure potential failure modes are eliminated. Pursu ant to BOEM

- 2010

- 0034 Interim Final Rules implemented additional considerations of a minimum of 2 independent barriers for both internal and external flow paths in addition to proper positive and negative testing of the barriers

.

The proper training of crew members and awareness to identify and handle well control event is the

best wa y prevent a blowout incident. Contractor ’s personnel and service personnel training requirements are verified per regulatory requi r ements per guidelines issued in BOEM

- 2010

- 034

Interim Final Rules

. Drills are performed frequently to verify crew training and improve reaction times.

Good communication between rig personnel, office support personnel is critical to the success of the operations. Pre

- spud meetings are conducted with rig crews and service providers to discuss, inform and as needed improve operations and well plans for safety and efficiency considerations. Daily meetings are conducted to discuss planning and potential hazards to ensure state of preparedness

and behavior is enforced to create an informed and safe culture for the operations. Any changes in the planning and initial wellbore design is incorporated and communicated in a Management of Change (MOC) process to ensure continuity for all personnel.

Use of established good oil field practices that safeguard crews and equipment are integrated to incorporate LLOG’s, the contractor and service provider policies.

Additional personnel and equipment will be used as needed to elevate awareness and provide rea l time monitoring of well conditions while drilling such as MWD/LWD/PWD tools used in the bottom hole assemblies. The tool configuration for each open hole section varies to optimize information gathered including the use of Formation

- Pressure

- While

- Drill ing (FPWD) tools to establish real time formation pressures and to be used to calibrates pore pressure models while drilling. Log information and pressure data is used by the drilling engineers, geologist and pore pressure engineers to maintain well control and reduced potential events such as well control events and loss circulation

events.

Mud loggers continuously monitor return drilling fluids, drill gas levels and cuttings as well as surface mud volumes and flow rates, rate of penetration and lithology/paleo to aid in understanding trends and geology being drilled. Remote monitoring of real time drilling parameters and evaluation of geologic markers and pore pressure indicators is used to identify potential well condition changes.

Proper equipment maintenance and inspection program for same to before the equipment is required. Programmed equipment inspections and maintenance will be performed to ensure the equipment operability and condition. Operations will cease as needed in order to ensure equipment and well conditions are maintained and controlled for the safety of personnel, rig and subsurface equipment

and the environment.

I) Measures to conduct effective and early intervention in the event of a blowout

In conjunction with the LLOG Exploration’s “Well Control Emergency Response Plan” and as required by NTL 2010

- N06, the following is provided to demonstrate the potential time needed for performing secondary intervention and drilling of a relief well to handle potential worst case discharge for t he proposed prospect. Specific plans are integrated into the Helix Well Containment Groups procures to be approved and submitted with the Application for Permit to Drill. Equipment availability, backup equipment and adaptability to the potential scenarios will need to be addressed based on the initialBLOWOUT SCENARIO

5 site assessment of the seafloor conditions for intervention operations. Relief well equipment such as backup wellhead equipment and tubulars will be available in LLOG’s inventory for immediate deployment as needed to address frilling the relief well(s).

SITE SPECIFIC PROPOSED RELIEF WELL AND INTERVENTION PLANNING

No platform was considered for drilling relief wells for this location due to location, water depth and lack of appropriate platform within the area. For this reason a moored or DP MODU will be preferred / required. If accessible and needed, there is presently located at the drill center for the MC 707

locations infrastructure to be used to tie

- in and access production flowlines to a shelf produc tion facility in GI 115 presently operated by LLOG. This may be a source for a “cap and flow” scenario.

Relief well sites have been initially identified to address blowout scenarios for the potential geologic targets for the proposed wells. Two relief w ell surface locations are proposed for the clustered 3

p roposed Exploration Plan wells in water depths around 2100’

. Actual relief well sites are common to

different p roposed Exploration Plan wells. Based o n actual seafloor state unforeseen at this time, the final location(s) may need to be revised. The locations have been selected based on proximity to the targets sands and potential shallow hazards.

LLOG selected Tesla Offshore LLC to provide this archaeological assessment of the proposed well and associated anchor radius based on high-resolution deep tow geophysical site survey centered in Block 707 (OCS-G 25103) with survey coverage extending into the adjacent survey blocks (MC 708, 751, and 752). The geophysical survey was conducted by Tesla Offshore between September 22 nd 

### and 27 th 

### , 2007,
aboard the M/V Terry Bordelon . A dedicated chase vessel was employed for acoustic tracking. An archaeological assessment based on the data set was prepared by Tesla Offshore and submitted to LLOG (reference number 07- 263 -13). Complete sonar survey coverage was obtained for the entire designated 7,000 foot radius surrounding the proposed well site. LLOG operates lease OCS-G 25103 and contracted Tesla Offshore, LLC to provide this archaeological analysis (NTL No. 2005-G07 ) in accordance with the Bureau of Ocean Energy Management, Gulf of Mexico OCS Region.

This archaeological assessment is intended to complement the geo-hazards assessment prepared under separate cover, which addresses hazard concerns in compliance with NTL 2008-G05 and Deepwater Benthic Communities requirements stipulated in NTL 2009-G40.

Water depth is approximately 1,570 feet surrounding the proposed drill site. Water depths across the survey grid increased to the east by an approximate rate of 210 feet per mile.

are reportedly silty clay (USDI, MMS Visual No. 3, 1983).TESLA OFFSHORE

Seafloor installations within 2,000 ft of the proposed surface location include Well No. SS1 in Block 707, located approximately 860 ’ to the SW , and its associated pipelines. The LLOG 3” pipeline (Segment 17505), LLOG 6” pipeline (Segment 17458), and LLOG 6” pipeline (Segment 17457) are parallel to one another and extend from Well No. SS1 to the WNW, while the LLOG 6” pipeline (Segment 18603)

and the LLOG 2” pipeline (Segment 18605) are parallel to one another and extend
from Well No. SS1 to the SSE. The LLOG 2” pipeline (Segm ent 18605) is located closest to the proposed surface location, approximately 710 ’ to the SW. All of these pipelines were installed following survey data acquisition, therefore their reported positions should be assumed correct; care should always be exercised near the reported position of any pipeline. The only other infrastructure within the survey grid is P&A Well No. 1 in Block 751, located approximately 8,4 30 ’ to the SW.

Magnetic data

is not required for survey in these water depths per NTL 2005- G07and NTL 2008-G05 (extended by NTL 2013-G02).

Side scan sonar verified that the seafloor immediately surrounding the proposed well site was clear of protruding obstructions. Three sonar targets were identified within the survey grid, and include targets 2, 3, and 4. Sonar target 1 was identified in Block 705 from supplemental survey data shot as part of an associated pipeline route survey. None of the reported targets are located within 2,000’ of the proposed surface location. Target No. 2 is a semi-ci rcular object measuring approximately 41’ by 11’ with 6.5’ of measured relief above the surrounding seafloor, and is located approximately 9,49 0’ WNW of the proposed well site. Target No. 3 is amorphous and measures approximately 70' by 40' with no measured relief above the surrounding seafloor, and is located approximately 5, 790 ’ NW of the proposed well

site. Target no. 4 consists of three parallel linear features measuring approximately 26’ by 8’ with no measured relief above the surrounding seafloor . It is located approximately 6,620 ’ NNE of the proposed well site. The targets do not appear to be culturally significant, and likely represent man-made debris or discrete areas of seafloor texture changes related to the numerous faults present in the survey area. Sonar data also recorded numerous fault scarps and outcrops; the nearest fault scarp is located approximately 1, 800 ’ WSW of the proposed well site. The nearest outcrop, which was an isolated feature, is located approximately 1,710’ SE of the proposed surface location. Two possible expulsion features were observed on the sonar data, located approximately 3,620 NE and 3, 520 ’ SW of the proposed surface

location.

Supplemental subbottom data showed penetration up to approximately 120 feet, consisting of well stratified, parallel layered, moderately reflecting sediments directly underneath the proposed well site. Numerous discrete faults were recorded throughout the survey area, most of which could not be connected across survey lines. Faults were recorded on the survey line closest to the proposed well site at depths of 15’ to 20’ BML approximately 280 ’ and 370 ’ to the SW. There is noTESLA OFFSHORE

of wrecks or other cultural debris were observed on the subbottom data.

No evidence of potential cultural resources was observed at the proposed well location. The proposed well site will be marked with DGPS during rig moves and drilling to comply

with the BOEM On -Site Requirements specified in NTL No. 2008-G05 (extended by NTL 2013-G02), Section VI, Item B-2(a). Pursuant to 30 CFR 550.194 (c), 30 CFR 550.101 (c), and NTL No. 2005-G07 , if any archaeological or potentially historically significant materials are observed during lease development, operations will immediately cease in that area and appropriate BOEM/BSEE personnel will be notified within 48 hours of discovery.

LLOG Exploration Offshore, L.L.C. and subcontractors will apply the safest and best available technologies during rig moves and drilling operations.

Features or areas that could support high density sensitive sessile benthic communities are not located within 2,000ft of the proposed well location. The closest occurrence of sensitive biology is

located 2,159ft to the WSW

. A ny seabed anchors will be at least 250ft from any area with the potential

to host sensitiv e sessile benthic communities.

The s ediment plume from the cuttings pile from the existing well located

Ladies/Gentlemen:
Gardline Surveys Inc was contracted by LLOG Exploration Offshore LLC to prepare a Site Clearance
Letter for the proposed MC707

- C well surface location in Mississippi Canyon, Block 707 (OCS

- G

25103 ). This letter addresses location prox imity to potential sensitive sessile benthic community sites.
LLOG Exploration Offshore LLC plans to drill the proposed exploration well from an anchored drilling
module; therefore, an anchoring assessment is included in this well clearance letter.

This sensitive sessile benthic community summary letter is issued as a supplement to Gardline Report
No. 9946 entitled: 3D Geohazard Assessment, Gulf of Mexico, Mississippi Canyon Block 707, dated
January 2014 . A Biological, Physical and Socioeconomic Map is included at the end of this appendix
illustrating the areas of potential seabed impact.

**Potential Sensitive Sessile Benthic**  **Communities.**
Features or areas that could support high density sensitive sessile benthic communities are not

located within 2 ,000ft of the proposed well location. The closest occurrence of sensitive biology is

located 2,022ft to the southwest. A ny seabed anchors will be at least 250ft from any area with the
potential to host sensitiv e sessile benthic communities.

## E. Oil Spill Response Discussion

See the following Oil Spill Response Discussion.

### SPILL RESPONSE DISCUSSION

For the purpose of NEPA and Coastal Zone Mana gement Act analysis, the largest spill volume originating from the proposed activity would be a well bl owout during drilling operations,
estimated to be 140,953 barrels of crude oil with an API gravity of 26.9°.

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 BO EM website. The results are shown in Figure 1. The BOEM OSRAM identifies a 4% probability of impact to the shorel ines of Plaquemines Parish, Louisiana within 10 days. Plaquemines Parish includes Barataria Bay, the Mississippi
River Delta, Breton Sound and th e affiliated islands and bays. This region is an extremely sensitive habitat and serves as a migratory, breeding, feeding and nursery habitat for numerous species of wildlife. Beaches in th is area vary in grain particle size and can be classified as fine sand, shell or perched shell beaches. Sa ndy and muddy tidal flats are also abundant.

Response

LLOG Exploration Offshore, L.L.C. will make every effort to respond to the Worst Case Discharge as effectively as practicable. A desc ription of the response eq uipment under contract

to contain and recover the Wors t Case Discharge is shown in Figure 2.

Using the estimated chemical and physical charact eristics of crude oil, an ADIOS weathering model was run on a similar product from the ADIO S oil database. The results indicate 13% or approximately 18,324 barrels of crude oil would be evaporated/dispersed w ithin 24 hours, with approximately 122,629 barrels remaining.

Spill Response MC 707, Well No. 2 Barrels of Oil

WCD Volume 140,953

Less 13% natural evaporation/dispersion 18,324

Remaining volume 122,629



### 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, tr avel time to the site and deployment. Figure 2 also indicates how operations will be supported.

LLOG Exploration Offshore, L.L.C.’s Oil Spill Response Plan includes alternative response technologies such as dispersants and in-situ burn. Strategies will be decided by Unified Command based on the size of the spill, weather and potential impacts. 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 dail y dispersant capability of 7,540 barrels. If the conditions are favorable for in-situ burning, the proper approvals have been obtained and the proper planning is in place, in-situ burning of oil may be attempted. Slick containment boom would be immediately called out and on-scene as soon as possible. Offshore response strategies may include attempting to skim utilizing CGA’s spill response equipment, with a total derated skimming capacity of 141,601 barrels. Temporary st orage associated with skimming equipment equals 10,198 barrels. If additional storage is needed, a 25,000 barrel storage barge, three 20,000 barrel storage barges, and a 47,000 barrel storage ba rge may be mobilized and centrally located to provide temporary storage allo wing the skimmers to stay in th e area of operations as much as possible. Safety is first priority. Air monito ring will be accomplished and operations deemed safe prior to any containment/skimming attempts.

If the spill went unabated, shoreline impact in Plaquemines Parish, Louisiana would depend upon existing environmental conditions. Shorelin e protection would include the use of CGA’s

near shore and shallow water skimmers with a totaled derated sk imming capacity of 22,086 barrels. Temporary storage associated with skim ming equipment equals 825 barrels. If additional storage is needed, a 23,000 barrel storage barge may be mobilized and centrally located to provide temporary storage allowing the skimmers to stay in the area of operations as much as possible. Onshore response may include the de ployment of shoreline bo om on beach areas, or protection and sorbent boom on vegetated areas. Master Service Agreements with AMPOL and
OMI Environmental will ensure access to 147,00 0 feet of 18” shoreline protection boom. Figure

2 outlines individual times needed for procurem ent, load out, travel time to the site and deployment. Strategies would be based upon survei llance and real time traj ectories that depict areas of potential impact given actual sea and w eather conditions. The Stat e of Louisiana Initial Oil Spill Response Plan for Plaquemines Parish and Unified Command would be consulted to ensure that environmental and special economic resources would be co rrectly identified and prioritized to ensure optimal protection. Shorel ine protection strategies depict the protection response modes applicable for o il spill clean-up operati ons. The State of Louisiana Initial Oil Spill Response Plan provides detailed shoreline protection strategies for this area, and it describes necessary action to keep the oil spill from entering Louisiana’s coastal wetlands, based on the assumption that removal of the released oil will be much easier and less damaging to fragile coastal ecosystems if done in the open waters of the Gulf of Mexico. Supervisory personnel have the option to modify the deploym ent and operation of equipment allowing a more effective response to site-speci fic circumstances. LLOG Exploration Offshore, L.L.C.’s contract Spill Management Team holds a copy of the State of Louisiana Initial Oil Spill Response Plan.

Based on the anticipated worst case discharge sc enario, LLOG Exploration Offshore, L.L.C. can be onsite with contracted oil spill recovery equi pment with adequate response capacity to contain and recover surface hydrocarbons, and prevent land impact, to the maximum extent practicable, within an estimated 57 hours (based on the equi pment’s Effective Daily Recovery Capacity (EDRC)).

### Initial Response Considerations Actual actions taken during an oil spill response will be based on many factors which include but

are not limited to:

• 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

LLOG Exploration Offshore, L.L.C. will take acti on 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 supe rvised by the designation of a SIMOPS group as necessary for close quarter vessel response activitie s. Most often, this gr oup will be used during source control events that require a significant nu mber of large vessels operating independently, but in coordination to complete a common objective, in a small area and in close coordination and support of each other. This group must also monitor the subsurface activ ities of each vessel (ROV, dispersant application, well control sup port, etc.). The SIMOPS group leader reports to

the Source Control Section Chief.

In addition, these activities will be monitored by the spill mana gement team (SMT) and Unified

Command via a structured Common Operating Picture (COP) esta blished 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 agen cies will be notified

• ICS 201, Initial Report Form will be completed

• Initial Safety plan will be written and published

• Unified Command will be established

o Overall safety plan developed to reflect the operational situa tion and coordinated objectives

o Areas of responsibility esta blished for Source Control a nd each surface operational

site

o On-site command and control established

### Decanting Strategy Recovered oil and water mixtures will typically se parate into distinct phases when left in a quiescent state. When separati on occurs, the relatively clean water phase can be siphoned or decanted back to the recovery point with minima l, if any, impact. Decanting therefore increases the effective on-site oil storage capacity a nd equipment operating time. FOSC/SOSC approval will be requested prior to decanting operations. This practice is routinely used for oil spill

recovery.

Dedicated off-shore skimming systems

General

• Deployed to the highest concentration of oil

• Assets deployed at safe distance from aer ial 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 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 dr aft of <10 feet when fully loaded

Storage Vessels

• Establish availability of CGA c ontracted assets (See Appendix E)

• Early call out (to allow for tug boa t acquisition and deployment speeds)

• Phase mobilization to allow storage vessels to arrive at the same time as skimming

systems

• Position as closely as possible to ski mming assets to minimize offloading time

Vessels of Opportunity (VOO)

• Use {Company Name}’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

• Expect mission specific and sa fety 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 st orage if appropriate

• 

### Maximize non-organic storage approp riate to vessel limitations

• 

### Decant as appropriate after approv al 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 a nd 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. Safety will be the overriding factor in all operations and will cease at the orde r 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 tra iling skimming unit’s organic, V-shaped boom and skimmer (see page 7, CGA Equipment Guide Book and Tactic Manual (CGATM)

• Use secondary vessels and heavy sea boom to widen boom swath beyond normal skimming system limits (see page 15, CGATM)

• Consider night-time operations, fi rst considering safety issues

• Utilize all available advanced technology syst ems ( 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 sk imming 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 in crease 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 o nboard storage is not available

• Maximize use of the organic recovered o il storage capacity of the skimming vessel

Command, Control, and Communications (C 3 

### )

• Publish, implement, and fully test an appropriate communications plan

• Design an operational scheme, maintain ing a manageable span of control

• Designate and mark C 3 

### vessels for easy aerial identification

• Designate and employ C 3 

### aircraft for task forces, groups, etc.

• Use reconnaissance air craft and Rapid Res ponse Teams (RAT) to confirm the presence

of recoverable oil

### Near Shore Response Actions

Timing

• Place near shore assets on standby and depl oy in accordance with planning based on the actual situation, actual traj ectories and oil budgets

• VOO identification and training in advance of spill nearing sh oreline 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

Equipment Deployment

Surveillance

• Provide trained observer to direct skimming operations

• Continual surveillance of oil movement by re mote 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 Re sponse Team level (Region 6)

Vessel Deployment Dedicated Near Shore skimming systems

• Fast Response Vessels (FRV)

• Egmopol and Marco Shallow Water Skimmer (SWS)

• Operate with aerial spotter directi ng systems to observed oil slicks

VOO

• Use LLOG Exploration Offshore, L.L.C.’s contracted resources as applicable

• Industry vessels are usually best for depl oyment 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 sa fety 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

• Environmental risk assessments (ERA) to determine prioritie s for area protection

• Time to acquire personnel and eq uipment and their availability

• Previous contingency planning contained in the appropriate Area Contingency Plan, and currently for Louisiana, The State of Loui siana Initial Oil Spill Response Plan, Deep Water Horizon, dated 2 May 2010

Actions

Placement of boom

• Position boom in accordance with the ERA based on the actual situation or the appropriate ACP

• Assess timing of booming operations to ensure it is where it needs to be at time of impact. 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

• Shoreline Cleanup and Assessment Team Reports and recommendations

• Determination of Archeological site s 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

• Staging of equipment and housing of respons e personnel as close to the job site as possible to maximize on-site work time

• Boom tending, repair, replacement and security (u se of local assets may be advantageous)

• Constant awareness of weather and oil moveme nt for resource redeployment as necessary

• In-situ burn may be considered when marshes have been impacted

• Passive clean up of marshes should be consider ed and appropriate stoc ks of sorbent boom and/or sweep obtained

• Earthen berms and shoreline protection boom may be considered to protect sensitive

inland areas

### Decanting Strategy Recovered oil and water mixtures will typically se parate into distinct phases when left in a quiescent state. When separati on occurs, the relatively clean water phase can be siphoned or decanted back to the recovery point with minima l, if any, impact. Decan ting therefore increases the effective on-site oil storage capacity a nd 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 rela tion 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 a nd/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 opera tions ceased when seas reache d 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 wint er and easterly winds in the summer. Average wind speed is generally 14-15 mph along the coast. Wave he ights 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 temperatur e will range from 50 and 60  ̊ F.

The Atlantic and Gulf of Mexico hurricane seas on is officially from 1 June to 30 November. 97% of all tropical activity occurs within this window. The Atlant ic 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 occurri ng then. Maximum activity is in early to mid September. Once in a few years there may be a hurri cane occurring "out of season" - primarily in May or December. Globally, September is the mo st active month and May is the least active

month.

two.

7. All activities that involve seafloor disturbances, including anchor emplacemen ts, in any OCS block designated by the BOEMRE as having high

- probability for the occurrence of shipwrecks or prehistoric sites, including such blocks that will be affected that are adjacent to the lease block in which your planned activity will occur. I f the proposed activities are located a sufficient distance from a shipwreck or prehistoric site that no impact would occur, the EIA can note that in a sentence or two.

8. All activities that you determine might have an adverse effect on endangered or threatene d marine

mammals or sea turtles or their critical habitats.

9. Production activities that involve transportation of produced fluids to shore using shuttle tankers or barges.Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

## B. Impact Analysis

LLOG does not anticipate any unforeseen incidents from the proposed activities which could significantly impact the associated environment. LLOG activities

associated with this Revised Exploration Plan (Plan) will be performed with prudent and industry accepted standards, and in compliance with the federal agency regulations and oversight.

The “Oil Spills Information” Section of this Plan details the potential worse case discharge volume which has been calculated based on the new Bureau of Ocean Energy Management (BOEM ) Notice to Lessees (NTL 2010

- N06). R esponse details associated with an unanticipated spill from this site are detailed in our Regional Oil Spill Response Plan (OSRP) which outlines the potential spill scenario, spill volumes, anticipated trajectory of the spill, response equipment

av ailable, and actions to be taken to respond to the potential spill incident. Additional measures implemented by LLOG is trajectory analyses to be obtained prior to and during the proposed activities, contractual arrangements with well control specialists and preliminary reviews of potential well intervention scenarios, and to supplement existing contracted response/clean

- up equipment with equipment offered by Helix which specializes in subsea deepwater well intervention, containment and processing.



## S ite Specific at Offshore Location

• Designated Topographic Features

There are no anticipated emissions, effluents, physical disturbances to the seafloor, wastes transported to shore, and/or accidents from the proposed activities that could cause impacts to topographic features.

The proposed surface disturbances within Mississippi Canyon Block 707

is located approximately 58 miles away from the from the closest designated topographic feature ( Diaphus Bank).

The crests of these designated topographic featur es in the northern Gulf are typically found below 10 m; therefore, concentrated oil from a surface spill is not likely to reach sessile biota. S ubsurface spills could cause adverse impacts to a designated topographic feature; however, due to the

offset di stance this should not have an impact.

In the event of an unanticipated spill, LLOG would immediately implement its Regional Oil Spill Response Plan and active source control and countermeasures to minimize these potential impacts.Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

### • Pinnacle Trend Area Live Bottoms

There are no anticipated emissions, effluents, physical disturbances to the seafloor, wastes sent to shore and/or accidents from the proposed activities that could cause impacts to a pinnacle trend area.

The proposed surface disturbance within Mississippi Canyon Block 707 is located a significant distance (> 1 00 miles) from the closest pinnacle trend live bottom stipulated block. The crests of these pinnacle trend areas are much deeper than 20 m . In the event of an accidental oil spill from the proposed activities, the gravity of such oil (high gravity condensate and/or diesel fuel) would rise to the surface, quickly dissipate, and/or be swept clear by currents moving around the bank; and thus not impacting the pinnacles.

During the surface location disturbance review, LLOG reviews potential surface impacts, and would be able to identify any pinnacles within the vicinity and would avoid placement of any surface disturbances such as a drilling rig and associated anchors. T hese surface locatio n disturbance areas would be avoided and/or mitigated during the review and approval process by the BOEM.

In the event of an unanticipated spill, LLOG would immediately implement its Regional Oil Spill Response Plan and activate source

control and counter measures to minimize these potential impacts.

• Eastern Gulf Live Bottoms

There are no anticipated emissions, effluents, emissions physical disturbances to the seafloor, wastes sent to shore, and/or accidents from the proposed activities that could cause i mpacts to Eastern Gulf live

bottoms.

The proposed surface disturbance within Mississippi Canyon Block 707 is located a significant distance (> 1 0 0 miles) from the closest Eastern Gulf live bottoms stipulated block. D uring the surface location disturbanc e review, LLOG previews potential surface impacts, and would be able to identify any live bottom areas within the vicinity and would avoid placement of any surface disturbances such as a drilling rig and associated

anchors. In the event of an accidental o il spill from the proposed activities, the gravity of such oil (high gravity condensate and/or diesel fuel) would rise to the surface, quickly dissipate, and/or be swept clear by currents moving around the bank; and thus not impacting the Eastern Gulf

live bottoms because of the depth of the features and dilutions of spills.Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

### In the event of an unanticipated spill, LLOG would immediately implement its Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potentia l impacts.

• Chemosynthetic Communities

Water depths in Mississippi Canyon Block 707 range from 1525’ to 1575’ including anchor radius. T he proposed activities are not located within the vicinity of any known chemosynthetic communities, which typically o c cur in water depths greater than 300 meters. Based on the water depth, there are no anticipated emissions, effluents, emissions physical dist urba nces to seafloor, wastes sent to shore, and/or accidents from the proposed activities that could impact these types of communities.

• Water Quality

Bottom disturbances which may result based on placement of drilling rigs during an exploratory phase could increase water column turbidity and redistribution of any accumulated pollutants in the water column; which

c ould cause temporary impacts on w ater quality conditions in the immediate vicinity.

Associated overboard effluents are regulated by the EPA Region VI NPDES General Permit GMG290000 which mandates volume discharge rate limitations, certain testing requirem ents for toxicity and oil and grease limitations. A s such, it is not anticipated these discharges authorized under the approved EPA NPDES permit will cause significant adverse impacts to water quality.

Certain wastes generated from the proposed activitie s will be manifested and sent to shore for treatment and/or disposal at approved facilities. Other waste which may be considered hazardous will be collected and transported in sealed containers and transported to approve disposal sites

in accordance with the RCRA regulations and guidelines.

An accidental oil spill release from the proposed activities, and cumulative similar discharge activity within the vicinity could potentially cause temporary impacts to water quality. In the event of such a r elease, t he water quality would be temporarily affected by the dissolved components and small droplets. Currents and microbial degradation would remove the oil from the water column or dilute the constituents to background levels.

In the event of an unanticipated blowout, LLOG will implement industry wide standards for using proven equipment and technology for such responses. LLOG would immediately implement its Regional Oil SpillRevised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

### Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Fisheries

Accidental oil spill releases from the proposed activities, and cumulative similar discharge activity within the vicinity may potentially cause some detrimental effects on fisheries. It is unlikely a spill would occur; however, such a release in open waters closed to mobile adult finfish or shellfish would likely be sub

- lethal 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.

In the event of an unanticipated blowout, LLOG will implement industry wide standards for using proven equipment and technology for such responses. LLOG would immediately implement its Regional Oil Spill Response Plan an d activate source control and countermeasures to minimize these potential impacts.

• Marine Mammals

GulfCet II studies reveal that cetaceans of the continental shelf and shelf edge are comprised of bottlenose dolphin and Atlantic spotted dolphin. Squid eaters, including dwarf and pygmy killer whale, Risso’s dolphin and Cuvier’s beaked whale occur most frequently along the upper slope in areas outside of anticyclones.

As a result of the proposed activities, marine mammals may be adversely impacted by emiss ions, effluents, waste sent to shore and/or accidents.

Chronic and sporadic sub

- lethal effects would 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 s ources. Few lethal effects are expected from an accidental oil spill, chance collisions with service vessels and ingestion of plastic material.

The net results of any disturbance would depend on t he size and percentage of the population affected, ecologi cal 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 betwee n cetaceans and ship could cause serious injury or death (Laist et al., 2001).Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

### 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.

LLOG does not anticipate the incidental taking of any marine mammals as the result of the proposed activities. T he proposed activities will be conducted by our company and its contractors under the additional criteria

addressed in BSEE NTL No. 2012

- G01 “Marine Trash and Debris Awareness Training and Elimination” and Joint NTL No. 2012

- G01 “Vessel Strike Avoidance and Injured/Dead Protected Species Reporting”. The proposed operations will be conducted in accordance with the regula tions via manifesting waste sent to shore and ensuring such wastes are contained to prevent loss. Informational placards will be maintained on the facility, and LLOG and the associated contractors obtain training on at least an annual basis to ensure personnel are aware of the reporting and operational requirements.

LLOG will conduct the proposed activities under EPA’s Region VI NPDES General Permit GMG290000 which authorizes the discharge of certain effluents, subject to certain limitations, prohibitions and recordkeeping requirements. A s such, it is not anticipated these discharges authorized under the approved EPA NPDES permit will not cause significant adverse impacts to water quality.

In the event of an unanticipated blowout, LLOG will implement ind ustry wide standards for using proven equipment and technology for such responses. LLOG would immediately implement its Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Sea Turtles

Sma ll 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 drilling rigs, production facilities and service vessels. Drilling rigs and projec t vessels produce noise that could disrupt normal behavior patterns and create some stress to sea turtles, making them more susceptible to disease. A ccidental oil spill releases are potential threats which could have lethal effects on turtles. Contact an d/or consumption of this released material could seriously affect individual sea turtles. Most OCS related impacts on sea turtles are expected to be sub

lethal. Chronic and/or avoidance of affected areas could cause declines in survival or productivity, resulting in gradual population declines.Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

### LLOG will conduct the proposed activities under EPA’s Region VI NPDES General Permit GMG290000 which authorizes the discharge of certain effluents, subject to certain limitations, prohibitions and recordkeeping r equirements. A s such, it is not anticipated these discharges authorized under the approved EPA NPDES permit will not cause significant adverse impacts to water quality.

Additionally, LLOG and its contractors will conduct the proposed

activities under the additional criteria addressed by BSEE NTL No. 2012

- G01 “Marine Trash and Debris Awareness Training and Elimination” and

Joint NTL No. 2012

- G01 “Vessel Strike Avoidance and Injured/Dead Protected Species Reporting”. The proposed operations will be conduct ed in accordance with the regulations via manifesting waste sent to shore and ensuring such wastes are contained to prevent loss. Informational placards will be maintained on the facility, and LLOG and the associated contractors obtain training on at least an annual basis to ensure personnel are aware of the reporting and operational requirements.

In the event of an unanticipated blowout, LLOG will implement industry wide standards for using proven equipment and technology for such responses. LLOG would immediately implement its Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Air Quality

The proposed activities are located approximately 51 miles to the nearest

shoreline. LLOG has add ressed the air quality issues associated with the proposed activities in the “Air Emissions Information” section of this Plan as a result of the proposed activities.

• Ship Wreck Sites (Known or Potential)

There are no physical disturbances to the seafloor which could impact known or potential shipwreck sites, as the review of high resolution shallow hazards data indicate there are no known or potential shipwreck sites located within the survey area. As such, LLOG does not anticipate any IPF’s as a result of the proposed activities.

• Prehistoric Archaeological Sites

There are no physical disturbances to the seafloor which could cause impacts to prehistoric archaeological sites, as the review of high resolution shallow hazards data and supporting studies di d not reflect the occurrence of prehistoric archaeological sites. As such LLOG does not anticipate any IPF’s as a result of the proposed activities.Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

### Vicinity of Offshore Location

• Essential Fish Habitat

As a result of the proposed activities, essential fish habitat may be adversely impacted by effluents and/or accidents.

An Accidental oil spill that may occur as a result of the proposed activities has potential to cause some detrimental effects on essential fish habitat. It is unlikely that an accidenta l oil spill release would occur; however, if a spill were to occur in close proximity to finfish or shellfish, the effects would likely be sub

- lethal 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.

In the event of an unanticipated blowout, LLOG will implement industry wide standards for using proven equipment and technology for such responses. LLOG would immediately im plement its Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Marine and Pelagic Birds

As a result of the proposed activities, marine and pelagic birds may be adversely impacted by an a ccidental oil spill, by the birds coming into

contact with the released oil.

In the event of an unanticipated blowout resulting in an oil spill, it is likely to have an impact based on the industry wide standards for using proven equipment and technology for such responses. In that event, LLOG will implement the Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Public Health and Safety

There are no anticipated emissions, effluents, wast es sent to shore, and/or accidents from the proposed activities that could cause impacts to the public health safety. BOEM classified the proposed objective area as absent of hydrogen sulfide.Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

### Coastal and Onshore

• Beaches

As a result of the propose d activities, beaches may be adversely impacted by an accidental oil spill. H owever, due to the distance from shore ( approximately 51 miles), and the response capabilities that would be implemented, no significant adverse impacts are expected. Both histo rical spill data and the combined trajectory/risk calculations referenced in the publication of OCS EIA/EA BOEMRE 2002

- 052 indicate there is little risk of contact or impact to the coastline and associated environmental

resources.

In the event of an unant icipated blowout, LLOG will implement industry wide standards for using proven equipment and technology for such responses. LLOG would immediately implement its Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Wetlands

As a result of the proposed activities, wetlands may be adversely impacted by an accidental oil spill. H owever, due to the distance from shore (approximately 51 miles) and the response capabilities that would be implemen ted, no significant adverse impacts are expected. Both historical spill data and the combined trajectory/risk calculations referenced in the publication of OCS EIA/EA BOEMRE 2002

- 052 indicate there is little risk of contact or impact to the coastline and associated environmental

resources.

In the event of an unanticipated blowout, LLOG will implement industry wide standards for using proven equipment and technology for such responses. LLOG would immediately implement its Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Shore Birds and Coastal Nesting Birds

As a result of the proposed activities, shore birds and coastal nesting birds may be adversely impacted by an accidental oil spill. However, due to the distance from shore (approximately 51 miles) and the response capabilities that would be implemented, no significant adverse impacts are expected. Both historical spill data and the combined trajectory/risk calculations

referenced in the publication of OCS EIA/EA BOEMRE 2002 -052 indicate there is little risk of contact or impact to the coastline and

associated environmental resources.Revised Exploration Plan Mississippi Canyon Block 707

LLOG would immediately implement its Regional Oil Spill Response Plan and activate source control and countermeasures to minimize these potential impacts.

• Coastal Wildlife Refuges

As a result of the propos ed activities, coastal wildlife refuges may be adversely impacted by an accidental oil spill. H owever, due to the distance from shore (approximately 51 miles) and the response capabilities that would be implemented, no significant adverse impacts are expe cted. Both historical spill data and the combined trajectory/risk calculations referenced in the publication of OCS EIA/EA BOEMRE 2002 -052 indicate there is little risk of contact or impact to the coastline and

associated environmental resources.

Other Resources Identified

LLOG has not identified any other environmental resources other than those

addressed above.Revised Exploration Plan Mississippi Canyon Block 707

– OCS -G- 25103 

## C. Impacts of Propos ed Activities

LLOG does not anticipate any impacts on the offshore site specific locations, offshore vicinity, and/or coastal and onshore environmental conditions based on the potential impacts identified in the EIA worksheets and historical operations in the exploration of this reservoir.



## D. Environmental Hazards

Mississippi Canyon Block 70 7 is not located within a geographic area impacted by strong environmental phenomena, other than potential hurricanes in the Gulf of

Mexico. The Gulf of Mexico may exper ience several hurricanes throughout the season which typically runs from June through November. A severe hurricane may impact the activities covered in this Plan. Such impacts may be damage to the drilling rig, the unanticipated release of hydrocarbons depending upon the current status of the well. Additionally, this block has the potential to be affected by the “Loop Current” which is a warm ocean current in the Gulf of Mexico that flows northward between Cuba and the Yucatan Peninsula, moves northward into the Gulf of Mexico, then loops east and south before exiting to the east through the Florida Straits. While the loop current is present approximately 95% of the time, it is most active in the summer and fall seasons.

To mitigate potential impacts to the well during impending hurricanes or loop currents, LLOG will take precautionary measures by securing the well, rig and evacuation of personnel; and will comply with the requirements of NTL’s 2008

- G09 and 2009-G10.



## E. Alternatives

LLOG did not consider any alternatives to reduce environmental impacts as a result of the proposed activities.



## F. Mitigation Measures

LLOG will not implement any mitigation measures to avoid, diminish or eliminate potential environmental resources, other than those required by regulation and policy.



## G. Consultation

LLOG has not contacted any agencies or persons for consultation regarding potential impacts associated with the proposed activities. Therefore, a list of such entities is not being provided.Revised Exploration Plan Mississippi Canyon Block 707
