A. CONCENTRATION Apache Deewpater LLC does not anticipate encountering any H 2 S during the proposed operations.

Based on the BOEM H 2 S Map, there are two bloc ks in Mississipp i Canyon Protraction Area that reported H 2 S occurrences. The closest of these blocks is MC 948 which is approximately 25.5 miles from the proposed locations. However, the closest well to the propos ed location(s) is the previously referenced OCS-G-21770 001, whic h did not report any occurrence of H 2 S. Based on the proximity of the ExxonMobil well to the pr oposed locations and the long distance to the reported H 2 S occurrences, both of which were less than 20ppm, Apache does not expect H 2 S at the proposed location(s).

B. CLASSIFICATION In accordance with Title 30 CFR 250.490(c), Ap ache Deepwater requests that Mississippi Canyon Blocks 554/555 be classified by the BOEM as H 2 S absent.Apache Deepwater LLC Page E

MARINE MAMMAL INFORMATION Under Section 7 of the Endangered Species Act (ESA) all federal agencies must ensure that any actions they authorize, fund or carry out are not likely to jeopardize the continued existence of a listed species, destroy or adversely modi fy its designated critical habitat.

In accordance with the 30 CFR 250, Subpart B, e ffective May 14, 2007, and further outlined in Notice to Lessees (NTL) 2008-G04, lessees/opera tors are required to address site-specific information on the presence of federally listed threatened or endangered species and critical habitat designated under the ESA and marine mammals protected under the Marine Mammal Protection Act (MMPA) in the area of proposed activities under this plan.

NOAA Fisheries currently lists the Sperm Whale, Leatherback Turtle, Green Turtle, Hawksbill, Turtle and the Kemp’s Ridley Turtle as en dangered and the Loggerhead Turtle and Gulf Sturgeon as threatened. Currently there are no de signated critical habitats for the listed species in the Gulf of Mexico Outer Continental Shelf; how ever, it is possible that one or more of these species could be seen in the area of our operations.

The Environmental Impact Analysis in “Section O” of this plan further discusses potential impacts and mitigation measures related to threatened and endangered species.

Apache Deepwater LLC has determined that the wo rst-case scenario from the activities in this EP does not supersede the worst-case scenario from our Re gional OSRP (0-685) approved April 18, 2013. Apache Deepwater LLC hereby certifies it has the capability to respond, to the maximum extent practicable, to a worst-case discharge, or a substan tial threat of such a discharge, resulting from the activities proposed in our Joint Initial EP.

E. SPILL RESPONSE DISCUSSION FOR NEPA ANALYSIS Spill Response Discussion is included in this section as Attachment H-1

.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 444,250 barrels of crude oil with an API gravity of 32°.

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 BS EE Oil Spill Risk Analysis Model (OSRAM) for the Central and

Western Gulf of Mexico available on the BSEE website. The results are shown in Figure 1. The BSEE OSRAM identifies an 11% probability of impact to the shorelines of Plaquemines Parish, Louisiana within 30 days. Plaquemines Parish includes Barataria Bay, the Mississippi River Delta, Breton Sound and the affiliated islands and bays. This region is an extremely sensitive habitat and serves as a migratory, breeding, feedi ng and nursery habitat for numerous species of wildlife. Beaches in this area vary in grain particle size and can be classified as fine sand, shell or perched shell beaches. Sandy and muddy tidal flats are also abundant.

Response

Apache Deepwater LLC will make every effort to respond to the Worst Case Discharge as effectively as practicable. A de scription of the response equipmen t under contract to contain and

recover the Worst 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 14% or approximately 62,195 barrels of crude oil would be evaporated/dispersed w ithin 24 hours, with approximately 382,055 barrels remaining.

Figure 2 outlines equipment, personnel, materials and support vessels as well as temporary storage equipment available to respond to a sp ill of approximately 382,055 barrels. The volume accounts for the amount remaining after evaporatio n/dispersion at 24 hours. The list estimates individual times needed for proc urement, load out, travel time to the site and deployment. Figure

2 also indicates how operations will be supported.

Apache Deepwater LLC’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 aircraft s and 4 sorties (8,000 gall ons) from the Basleraircraft would provide a daily dispersant ca pability 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 attempte d. Slick containment boom would be immediately

called out and on-scene as soon as possible. Offshore response stra tegies may include attempting to skim utilizing a variety of CGA, MSRC, and NRCC equipment, with a total derated skimming capacity of 935,182 barrels. Temporary storage a ssociated with skimming equipment equals 348,944 barrels. If additional storage is neede d, an 80,000 barrel storage barge, an 83,937 barrel storage barge, and four 107,285 barr el storage barges may be mob ilized and centrally located to provide temporary storage allowing the skimmers to stay in the 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. Shoreline protection would include the use of CGA’s, MSRC’s, and NRCC’s near shore and shallow water skimmers with a totaled derated skimming capacity of 230,695 barrels. Temporary storage a ssociated with skimming equipment equals 6,890 barrels. If additional storage is neede d, an 86,948 barrel storage barge, a 25,000 barrel storage barge, three 20,000 barrel storage barges, and three 23,000 barrel storage barges may be mobilized and centrally located to provide temporary storage allowi ng the skimmers to stay in the area of operations as much as possible. On shore response may include the deployment of shoreline boom on beach areas, or protecti on and sorbent boom on vegetated areas. Master Service Agreements with AMPOL and OMI Envir onmental will ensure acc ess to 147,000 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 potentia l impact given actual se a and weather conditions. The State of Louisiana Initial Oil Spill Respon se Plan for Plaquemines Parish and Unified

Command would be consulted to ensure that environmental and special economic resources would be correctly identified and prioritized to ensure optimal protection. Shoreline protection strategies depict the protection response modes applicable for oil spill clean-up operations. The

State of Louisiana Initial O il Spill Response Plan provides detailed shoreline protection strategies for this area, and it describes necessary action to k eep the oil spill from entering Louisiana’s coastal wetlands, base d 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 deployment and operation of equipment allowing a more effective res ponse to site-specific circumstances. Apache Deepwater LLC’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 scenario, Apache Deepwater LLC can be onsite with contracted oil spill recovery equipment with adequate re sponse capacity to contain and recover surface hydrocarbons, and prevent land impact, to the maximum extent practicable, within an estimated 82 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

Apache Deepwater LLC will take action to provide a safe, aggressive response to contain and recover as much of the spilled oi l as quickly as it is safe to do so. In an effort to protect the environment, response actions wi ll 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.

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

• 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 patchesShoreline 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 areasDecanting 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.

FRU 8 foot seas HOSS Barge/OSRB 8 foot seas Koseq Arms 8 foot seas

OSRV 4 foot seasEnvironmental 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.FIGURE 1

COASTAL ZONE MANAGEMEN T (CZM) INFORMATION (30 CFR 550.213 and 550.243)

Under the direction of the Coastal Zone Mana gement Act (CZMA), the states of Alabama, Florida, Louisiana, Mississi ppi and Texas developed Coastal Zone Management Programs (CZMP) to allow for the supervision of the significant land and water use activities that take place within or that could significantly impact their respective coastal zones.

Any new or unusual technology will/will not be us ed by Apache Deepwater LLC in regards to spill control, cleanup, prevention, etc.

Relevant enforceable policies were considered in certifying consistency for Louisiana and Mississippi.

A certificate of Coastal Zone Management Consis tency for the state of Louisiana & Mississippi

is enclosed as Attachment N-1

.As authorized by the Federal Coastal Zone Mana gement Act (CZMA), The State of Mississippi developed a Coastal Management Program (CMP) to allow for the review of proposed Federal license and permit activities affecting any coas tal use or resources, in or outside of the Mississippi Coastal Zone.

The OCS related oil and gas exploratory and deve lopment activities having potential impact on the Mississippi Coastal Zone are based on the loca tion of the proposed facilities, access to those sites, best practical technique s for drilling locations, drilling equipment guidelines for the prevention of adverse environmen tal effects, effective environmental protection, emergency plans and contingency plans.

Below are goals identified by the State of Mississippi and our comments and/or corresponding

cross references:



### Mississippi Coastal Program (MCP) Enforceable Policies

Goal 1: To provide for reasonable industrial expansion in the coastal area and to ensure

the efficient utilization of waterfront industrial sites so that suitable sites are conserved for water dependent industry.

The activities proposed in th is plan are based out of Louisiana. The activities w ill not provide any industrial expansion on the coastal area of Mississippi. Therefore Mi ssissippi coastal areas will be conserved for water dependent industry.

Goal 2: To favor the preservation of the coas tal wetlands and ecosystems, except where a specific alteration of specifi c coastal wetlands would serv e a higher public interest in compliance with the public purposes of the pub lic trust in which the coastal wetlands are

held.

Goal 2 is addressed in Section O - Environm ental Impact Analysis. The nearest proposed

activities will be

__ miles from the Mississippi coast.

Goal 3: To protect, propagate and conserve the state’s seafood and aquatic life in

connection with the revitalization of the se afood industry of the State of Mississippi.

Goal 3 is addressed in Section O - Environmental Impact Analysis. Little impact to the seafood industry can be expected due to the activities occurring 50 miles from the Louisiana coast.

Goal 4: To conserve the air and waters of the state, and to protect, maintain and improve the quality thereof for public use, for the propagation of wildlife, fish and aquatic life, and for domestic, agricultural, industrial, recreati onal and other legitima te beneficial uses.

Goal 4 is addressed in Section B - General In formation, Section G - Air Emissions Information, and Section O - Environmental Impact Analysis.Goal 5: To put to beneficial use to the fullest extent of wh ich they are capable the water resources of the state, and to prevent the waste, unreasonable use, or unreasonable method

of use of water.

The activities proposed in this plan are based in Louisiana . As such, Mississippi’s water resources should not be impacted by the proposed activities. Activi ties occurring at the sites in

the OCS will be conducted in accordance with Re gional Oil Spill Response Plan approved April 18, 2013 referenced in Section H of this plan.

Goal 6: To preserve the state’s historical and archaeological resources, to prevent their destruction, and to enhance these resources wherever possible.

Goal 6 is addressed in Section B - General In formation and Section O - Environmental Impact Analysis.

Goal 7: To encourage the preservation of na tural scenic qualities in the coastal area.

Goal 7 is addressed in Section F - Waste Disc harges Information, Section G - Air Emissions Information, Section H - Oil Spill Information a nd Section O - Environmental Impact Analysis.

Goal 8: To assist local governments in the provis ion of public facilities services in a manner consistent with the coastal program.

As the proposed activities are located 50 miles from the Louisiana coast and are based out of a

shorebase in Fourchon, LA , local governments should not be affected.Apache Deepwater LLC Page O

### (B) ANALYSIS

Site

- Specific at Mississippi Canyon Block 554 and 555

Proposed operations consist of the drilling, completion and installation of subsea wellheads for 3 locations (MC 554 A, MC 555 A, MC 555B).

Operations will be conducted with either a Semisubmersible or DP Semisubmersible rig

.

1. Designated T opographic F eatures

Potential IPFs on topographic features include physical disturbances to the seafloor, effluents,

and accidents.

Physical disturbanc es to the seafloor : Mississippi Canyon Block 554 and 555 are 56 miles

from the closes

t designated Topographic Features Stipulation Block ( Sackett Bank ); therefore

, no adverse impacts are expected.

Effluents: Mississippi Canyon Block 554 and 555 are 56 miles from the closest designated

T opographic F eature s Stipulation Block ( Sackett Bank ); therefore

, no adverse impacts are expected.

Accidents: It is unlikely that an accidental surface or subsurface spill would occur from the proposed activities (refer to statistics in Item 5 , Water Q uality). Oil spills c ause damage to benthic organisms only if the oil contacts the organisms. Oil from a surface spill can be driven
into the water column; measurable amounts have been d ocumented down to a 10 m depth. At this depth, the oil is found only at concentrations sev eral orders of magnitude lower than the amount shown to have an effect on corals. Because the crests of topographic features in the Northern Gulf of Mexico are found below 10 m, no oil from a surface spill co uld reach their

sessile biota. Oil from a subsur face spill is not applicable due to the distance of these blocks from a topographic area. The activities proposed in this plan will be covered by Apache’s Regional OSRP (refer to information submitted in Section H ).

There are no other IPFs (including emissions and wastes sent to shore for disposal) from the proposed activities, which could impact topographic features.

2. Pinnacle T rend A rea L ive B ottoms

Potential IPFs on pinnacle trend area live bottoms include physical disturbances to the seafloor,

e ffluents, and accidents.

Physical disturbanc es to the seafloor : Mississippi Canyon Block 554 and 555 are 55 miles from the closest live bottom (pin nacle trend) area; therefore

, no adverse impacts are expected.Effluents: Mississippi Canyon Block 554 and 555 are 55 miles from the closest live b ottom (pinnacle trend) area; therefore

, no adverse impacts are expected.

Accidents: It is unlikely that an accidental surface or subsurface spill would occur from the proposed activities (refer to statistics in Item 5 , Water Q uality). Oil spills have the potential to

foul benthic communities and cause lethal and sublethal eff ects on live bottom organisms. Oil from a surface spill can be driven into the water column; measurable amounts have been documented down to a 10 m depth. At this depth, the oil is found only at concentrations several orders of magnitude lower than the amount shown to have an effect on marine organisms. Oil from a subsurface spill is not applicable due to the distance of these blocks from a live bottom (pinnacle trend) area. The activities proposed in this plan will be covered by Apache’s Regional
OSRP (refer to information submitted in Section H ).

There are no other IPFs (including emissions and wastes sent to shore for disposal) from the proposed activities which could impact a live bottom (pinnacle trend) area.

3. Eastern Gulf Live B ottoms

Potential IPFs on Eastern Gulf live bott oms include physical disturbances to the seafloor,
effluents, and accidents.

Physical disturbanc es to the seafloor : Mississippi Canyon Block 554 and 555 are not located in an area characterized by the existence of live bottoms, and this lease does not co ntain a Live

Bottom Stipulation requiring a photo documentation survey and survey report.

Effluents: Mississippi Canyon Block 554 and 555 are not located in an area characterized by the existence of live bottoms; therefore, no adverse impacts are expecte d.

Accidents: It is unlikely that an accidental surface or subsurface spill would occur from the proposed activities (refer to statistics in Item 5

, Water Q uality). Oil spills cause damage to live bottom organisms only if the oil contacts the organisms. Oil from a surface spill can be driven into the water column; measurable amounts have been documented down to a 10 m depth. At this depth, the oil is found only at concentrations several orders of magnitude lower than the

amount shown to have an effect o n marine invertebrates. Oil from a subsurface spill is not applicable due to the distance of these blocks from a live bottom area. The activities proposed in this plan will be covered by Apache’s Regional OSRP (refer to information submitted in Section

H )

.

There are no other IPFs (including emissions and wastes sent to shore for disposal) from the proposed activities which could impact an Eastern Gulf live bottom area.4. Benthic C ommunities

Mississippi Canyon Block 554 and 555 are located in wate r depths 984 feet (300 meters) or
greater. IPFs that could result in impacts to benthic communities from the proposed activities include physical disturbances to the seafloor.

Physical disturbances to the seafloor: Mississippi Canyon Block 554 and 555 are approximately 80 miles from a known benthic community site ( Benthic Mississippi Canyon

Block 969 ), listed in NTL 2009

- G40

. This Joint Initial Exploration Plan submittal includes the required maps, analyses, and statement(s). The proposed activities will be conducted in

accordance with NTL 2009

- G40 , which will ensure that features or areas that could support high

- density benthic communities will not be impacted.

If the DP Semisubmersible rig option is used for the proposed activities, then only an insign ificant amount of seafloor will be disturbed. In the event that a DP Semisubmersible is used, physical disturbances to the seafloor will be minimized and Apache’s proposed operations in Mississippi Canyon Block 554 and 555 would not cause impacts to benth ic communities.

There are no other IPFs (including emissions, effluents, wastes sent to shore for disposal, or accidents) from the proposed activities which could impact benthic communities.

5. Water Q uality

IPFs that could result in water quality degrad ation from the proposed operations in Mississippi Canyon Block 554 and 555 include disturbances to the seafloor, effluents and accidents.

Physical disturbances to the seafloor: Bottom area disturbances resulting from the emplacement of dr ill rigs, the d rilling of wells and the installation of platforms and pipelines

would increase water

- column turbidity and re

- suspension of any accumulated pollutants, such as

trace metals and excess nutrients. This would cause short

- lived impacts on water quality

conditi ons in the immediate vicinity of the emplacement operations.

Effluents: Levels of contaminants in drilling muds and cuttings and produced water discharg es, discharge

- rate restrictions and monitoring and toxicity testing are regulated by the EPA NPDES

per mit, thereby eliminating many significant biological or ecological effects. Operational discharges are not expected to cause significant adverse impacts to water quality.

Accidents: Oil spills have the potential to alter offshore water quality; however, it is unlikely that an accidental surface or subsurface spill would occur from the proposed activities. Between 1980 and 2000, OCS operations produced 4.7 billion barrels of oil and spilled only 0.001 percent
of this oil, or 1 bbl for every 81,000 bbl pro duced. The spill risk related to a diesel spill from drilling operations is even less. Between 1976 and 1985, (years for which data were collected), there were 80 reported diesel spills greater than one barrel associated with drilling activities.Conside ring that there were 11,944 wells drilled, this is a 0.7 percent probability of an

occurrence. If a spill were to occur, the water quality of marine waters would be temporarily affected by the dissolved comp onents and small oil droplets. Dispersion by curr ents and microbial degradation would remove the oil from the water column and dilute the cons tituents to background levels. Historically, changes in offshore water quality from oil spills have only been detected during the life of the spill and up to sever al months afterwards. Most of the components

of oil are insoluble in water and therefore float. The activities proposed in this plan will be covered by Apache’s Regional Oil Spill Response Plan (refer to information submitted in

Section H ).

There are no other IPFs (including emissions, physical disturbances to the seafloor, and wastes sent to shore for disposal) from the proposed activities which could cause impacts to water quality.

6. Fisheries

IPFs that could cause impacts to fisheries as a result of the proposed operations in Mississippi Canyon Block 554 and 555 include physical disturbances to the seafloor, effluents and accidents.

Physical disturbances to the seafloor: The emplacement of a structure or drilling rig results in

minimal loss of bot

tom trawling area t

o commercial fishermen. Pipelines cause gear conflicts

which result in losses of trawls and shrimp catch, business downtime and vessel damage. Most financial losses from gear conflicts are covered by the Fisher men’s Contingency Fund (FCF ). The emplacement and removal of facilities are not expected to cause significant adverse impacts

to fisheries.

Effluents: Effluents such as drilling fluids and cuttings discharges contain components and properties which are detrimental to fishery resou rces. Moderate petroleum and metal

contamination of sediments and the water column can occur out to several hundred meters down

current from the discharge point. Offshore discharges are expected to disperse and dilute to very near background levels in the water column or on the seafloor within 3,000 m of the discharge point, and are expected to have negligible effect on fisheries.

Accidents: An accidental oil spill has the potential to cause some d etrimental effects on
fisheries; however, it i

s unlikely that such an event would occur from the proposed activities (refer to Item 5

, Water Q

uality). The effects of oil on mobile adult finfish or shellfish would likely be sublethal and the extent of damage would be reduced to the c apacity of adult fi sh and

shell fish to avoid the spill, to metabolize hydrocarbons, and to excrete both met abolites and parent compounds. The activities proposed in this plan will be covered by Apache’s Regional
OSRP (refer to information submitted in Section H ).

There ar e no IPFs from emissions, or wastes sent to shore for disposal from the proposed activities which could cause impacts to fisheries.7. Marine M ammals

GulfCet II studies revealed that cetaceans of the continental shelf and shelf

- edge were almost

exclusivel y bottlenose dolphin and Atlantic spo tted dolphin. Squid eaters, including dwarf and pygmy killer whale, Risso’s dolphin, rough

- toothed dolphin, and Cuvier’s beaked whale, occurred most frequently along the upper slope in areas outside of anticyclones. IP Fs that could cause impacts to marine mammals as a result of the proposed operations in Mississippi Canyon

Block 554 and 555 include emissions, effluents, discarded trash and debris, and accidents.

Emissions : Noises from drilling activities, support ve ssels and helicopters may elicit a startle

reaction from marine mammals. This reaction may lead to disruption of marine mammals’ normal activities. Stress may make them more vulnerable to parasites, disease, environmental contaminants, and/or predati on (M ajors and Myrick, 1990). There is little conclusive evidence for long

- term displacements and population trends for marine mammals relative to noise.

Effluents: Drilling fluids and cuttings discharges contain components which may be detrimental

to marine mammals. Most operational discharges are dilut ed and dispersed upon release. Any potential impact from drilling fluids would be indirect, either as a result of impacts on prey items or possibly through ingestion in the food chain (API , 1989).

Discarded trash and debris: Both en tanglement in, and ingestion of debris have caused the death or serious injury of marine mammals (Laist, 1997; MMC, 1999). The limited amount of marine debris, if any, resulting from the proposed activities i s not expected to substantially harm marine mammals. Operators are prohibited from deliberately discharging debris as mandated by

MARPOL

- Annex V and the Marine Plastic Pollution Research and Control Act, and regulations imposed by various agencies includin g the United States Coast Guard (USCG) and the Environmental Protection Agency (EPA).

Apache will operate in accordance with the regulations and also avoid accidental loss of solid waste items by maintaining waste management plans, manifesting trash sent to shore, and using special precautions such as covering outside trash bins to prevent ac cidental loss of solid waste. Special caution will be exercised when handling and disposing of small items and packaging materials, particularly those made of non

- biod egradable, environmentally persistent mater ials such as plastic or glass.

Informational placards will be posted on all vessels and facilities having sleeping or food preparation capabilities. All offshore personnel, including contractors and other suppo rt

services

- related personnel (e.g. helicopter pilots, vessel captains and boat crews) will be indoctrinated on waste procedures, and will view the video (or Microsoft PowerPoint presentation)

, “Think About It” ( previously “All Washed Up: The Beach Litter Problem” ). Thereafter, all personnel will view the marine trash and debris training video annually. Offshore personnel will also receive an explanation from Apache management or the designated leaseoperator management that emphasizes their commitment to waste management in accordance

with NTL No. 2012

- G01

.

Accidents: Collisions between support vessels and cetaceans would be unusual events, however should one occur, death or injury to marine mammals is possible. Contract vessel operators can

avoid marin

e mammals and reduce potential deaths by maintaining a vigilant watch for marine mammals and maintaining a safe d istance when they are sighted. Vessel crews should use a reference guide to help identify the twenty

- eight species of whales and dolphins, and the single species of manatee that may be encountered in the Gulf of Mexico OCS. Vessel crews must report sightings of any injured or dead protected marine mammal species immediately, regardless of whether the injury or death is caused by their vessel, to the Marine Mammal and Sea Turtle Stranding Hotline at (888) 404

- 3922, the NMFS Southeast Regional Office at (727)

824

- 5312, or the Marine Mammal Stranding Network at (305) 862

- 2850 . In addition, if the injury or death was caused by a collision with a con tract vessel, the BOEM must be notified within 24 hours of the strike by email to protectedspecies@ boemre.gov . If the vessel is the responsible party, it is required to remain available to assist the respectiv e salvage and stranding

network as needed.

Oil spills have the potential to cause sublethal oil

- related injuries and spill

- related deaths to marine mammals. However, it is unlikely that an accidental oil spill would occur from the proposed activities (re f

er to Item 5

, Water Q uality). Oil spill response activities may increase vessel traffic in the area, which could add to changes in cetacean behavior and/or distribution, thereby causing additional stress to the animals. The effect of oil dispersants on cetaceans is not

known. The acu

te toxicity of oil dispersant chemicals included in Apache’s OSRP is considered to be low when compared with the constituents and fractions of crude oils and diesel products. The activities proposed in this plan will be covered by Apache’s OSRP (refer to information

submitted in accordance with Section H ).

There are no other IPFs (including physical disturbances to the seafloor) from the proposed activities which could impact marine mammals.

8. Sea T urtles

IPFs that could cause impacts to sea turtles as a result of the proposed operations include emissions, effluents, discarded trash and debris, and accidents. GulfCet II studies sighted most loggerhead, Kemp’s ridley and leatherback sea turtles over shelf waters. Historically these species have been sig hted up to the shelf’s edge. They appear to be more abundant east of the Mississippi River than they are west of the river (Fritts et al., 1 983b; Lohoefener et al., 1990). Deep waters may be used by all species as a transitory habitat.

Emissions: Noise from drilling activities, support vessels, and helicopters may elicit a startle
reaction from sea turtles, but th is is a temporary disturbance.Effluents: Drilling fluids and cuttings discharges are not know n to be lethal to sea turtles. Most operational discharges are diluted and dispersed upon release. Any potential impact from drilling fluids would be indirect, either as a result of impacts on prey items or possibly through ingestion in the food chain (API, 1989).

Discarded trash and debris: Both entanglement in, and ingestion of, debris have caused the death or serious injury of sea turtles (Balazs, 1985). The limited amount of marine debris, if any, resulting from the proposed activities is not expected to s ubstantially harm sea tu rtles. Operators are prohibited from deliberately discharging debris as mandated by MARPOL

- Annex V and the Marine Plastic Pollution Research and Control Act, and regulations imposed by various agencies including the United States Coast Guard (USCG) and the Environmental Protection Agency (EPA). Apache will operate in accordance with the regulations and also avoid accidental loss of solid waste items by maintaining waste management plans, manifesting trash sent to shore, and using special precautions such a s covering outside trash bins to prevent ac cidental loss of solid

waste. Special caution will be exercised when handling and disposing of small items and packaging materials, particularly those made of non

- biodegradable, environmentally persistent

mater ial s such as plastic or glass.

Informational placards will be posted on all vessels and facilities having sleeping or food preparation capabilities. All offshore personnel, including contractors and other support

services

- related personnel (e.g. helicopter pilots, vessel captains and boat crews) will be indoctrinated on waste procedures, and will view the video (or Microsoft PowerPoint presentation)

, “Think About It” ( previously “All Washed Up: The Beach Litter Problem” ). Thereafter, all personnel will view the marine trash and debris training video annually. Offshore personnel will also receive an explanation from Apache management or the designated lease operator management that emphasizes their commitment to waste management in accordance

with NTL No. 2012

- G01

.

Accidents: Collisions between support vessels and sea turtles would be unusual events, however should one occur, death or inju ry to sea turtles is possible. Contract vessel operators can avoid sea turtles and reduce potential deaths by maintaining a vigilant watch for sea turtles and maintaining a safe distance when they are sighted. Vessel crews should use a reference guide to help identify the five species of sea turtles that may be encounte red in the Gulf of Mexico OCS. Vessel crews must report sightings of any injured or dead protected sea turtle species immediately, regardless of whether the injury or death is caused by their vessel, to the Marine Mammal and Sea Turtle Stranding Hotline at (888) 404

- 3922, the NMFS Southeast Regional

Office at (727) 824

- 5312, or the Marine Mammal Stranding Network at (305) 862

- 2850 . In addition, if the injury or death was caused by a collision with a contract vessel, the BOEM must be notified within 24 hours of the strike by email to protectedspecies@ boemre.gov

. If the vessel is the responsible party, it is required to remain available to assist the respective salvage and stranding network as needed.

All sea turtle species and their life stages are vulnerable to th e harmful effects of oil through direct contact or by fouling of their food. Exposure to oil can be fatal, particularly to juvenilesand hatchlings. However, it is unlikely that an accidental oil spill would occur from the proposed

activities (refer to Ite m 5 , Water Q uality). Oil spill response activities may increase vessel traffic in the area, which could add to the possibility of collisions with sea turtles. The activities proposed in this plan will be covered by Apache’s Regional Oil Spill Response Plan (refer to

information submitted in accordance with Section H ).

There are no other IPFs (including physical disturbances to the seafloor) from the proposed activities which could impact sea turtles.

9. Air Q uality

Mississippi Canyon Block 554 and 555 is located 77 miles from the Breton Wilderness Area and

50 miles from shore. Applicable emissio ns data is included in Section G of the Plan.

There would be a limited degree of air quality degradation in the immediate vicinity of the proposed activities. Plan Emissions for the proposed activities do not exceed the annual exemption levels as set forth by BOEM . Accidents and blowouts can release hydrocarbons or
chemicals, which c ould cause the emission of air pollutants. However, these releases would not

i mpact onshore air quality because of the prevailing atmospheric conditions, emission height,
emission rates, and the distance s of Mississippi Canyon Block 554 and 555 from the coastline. There are no other IPFs (including effluents, physical disturbances to the seafloor, wastes sent to shore for treatment or disposal) from the proposed activities which would impact air quality.

10. Shipwreck S ites (known or potential )

IPFs that could impact known or unknown shipwreck sites as a result of the proposed operations

in Mississippi Canyon Block 554 and 555 include disturbances to the seafloor and accidents (oil spill)

. Mississippi Canyon Block 554 and 555 are not located i n or adjacent to an OCS block designated by BOEM as having a high probability for occurrence of shipwrecks. Apache will

report to BOEM the discovery of any evidence of a shipwreck and make every reasonable effort to preserve and protect that cultural resou rce. There are no other IPFs (including emissions, effluents, wastes sent to shore for treatment or disposal, or accidents) from the proposed activities which could impact shipwreck sites.

Accidents: An accidental oil spill has the potential to cause som e detrimental effects to shipwreck sites if the release were to occur subsea. However, it is unlikely that an accidental oil spill would occur from the proposed activities (refer to Item 5 , Water Quality). The activities proposed in this plan will be cover ed by Apache’s Regional Oil Spill Response Plan (refer to

information submitted in accordance with Section H ).

Apache is familiar with the provisions of NTL 2008

- G0 6 . BOEM has determined that there is enough data gathered for grid area 16, therefore, Apa che will not be conducting any AUV/ROV surveys either pre

- spud or post

- drilling operations for the purpose of biological and physical

observations.There are no other IPFs (including emissions, effluents, or wastes sent to shore for treatment or

disposal) from the proposed activities that could cause impacts to shipwreck sites.

11. Prehistoric A rchaeological S ites

IPFs that could cause impacts to prehistoric archaeological sites as a result of the proposed operations in Mississippi Canyon Block 554 and 555 are physical disturbances to the seafloor and accidents (oil spill s ).

Physical Disturbances to the seafloor: Mississippi Canyon Block 554 and 555 are located inside the Archaeological Prehistoric high probability lines. Apache will report to BOEM the discovery of any object of prehistoric archaeological significance and make every reasonable effort to preserve and protect that cultural resource.

If the DP Semisubmersible rig option is used for the proposed activities, then only an insignificant a

mount of seafloor will be disturbed. In the event that a DP Semisubmersible is used, physical disturbances to the seafloor will be minimized and Apache’s proposed operations in Mississippi Canyon Block 554 and 555 would not cause impacts to prehistoric ar chaeological

sites.

Accidents: An accidental oil spill has the potential to cause some detrimental effects to prehistoric archaeological sites if the release were to occur subsea . However, it is unlikely that an accidental oil spill would occur from the proposed activities (refer to Item 5 , Water Quality). The activities proposed in this plan will be covered by Apache’s Regional Oil Spill Response Plan (refer to information submitted in accordance with Section H ).

Apache is familiar with the provisions of NTL 2008

- G06. BOEM has determined that there is enough data gathered for grid area 16, therefore, Apache will not be conducting any AUV/ROV surveys either pre

- spud or post

- drilling operations for the purpose of biological and physical

observations.

The re are no other IPFs (including emissions, effluents, wastes sent to shore for treatment or disposal) from the proposed activities that could cause impacts to prehistoric archaeological

sites.

Vicinity of Offshore Location

1. Essential F

ish H abitat (EFH)

IPFs that could cause impacts to EFH as a result of the proposed operations in Mississippi Canyon Block 554 and 555 include physical disturbances t o the seafloor, effluents and accidents.

EFH includes all estuarine and marine waters and substrates in the Gulf of Mexico.Physical disturbances to the seafloor: The Live Bottom Low Relief Stipulation, the Live

Bottom (Pinnacle Trend) Stipulation, and the Eastern Gulf Pinnacle Trend Stipulation would prevent most of the potential impacts on live

- bottom comm unities and EFH from bottom disturbing activities (e.g., anchoring, structure emplacement and removal).

Effluents: The Live Bottom Low Relief Stipulation, the Live Bottom (Pinnacle Trend) Stipulation, and the Eastern Gulf Pinnacle Trend Stipulation would prevent most of the potential impacts on live

- bottom communities and EFH from operational waste discharges. Levels of contaminants in drilling muds and cuttings and produced

- water discharges, discharge

- rate restrictions, and monitoring and toxicity testing are regulated by the EPA NPDES permit, thereby eliminating many significant biological or ecological effects. Ope rational discharges are not expected to cause significant adverse impacts to EFH.

Accidents: An accidental oil spill has the potential to cause some detrimental effects on EFH. Oil spills that contact coastal bays and estuaries, as well as OCS waters wh en pelagic eggs and larvae are present, have the greatest potential to affect fisheries. However, it is unlikely that an oil spill would occur from the proposed activities (refer to Item 5 , Water Q uality). The activities proposed in this plan will be cover ed by Apache’s Regional OSRP (refer to information

submitted in Section H ).

There are no other IPFs (including emissions, or wastes sent to shore for treatment or disposal) from the proposed activities which could impact essential fish habitat.

2. Marine and P

elagic B irds

IPFs that could impact marine birds as a result of the proposed activities include air emissions, accidental oil spills, and discarded trash and debris fr om vessels and the facilities.

Emissions: Emissions of pollutants into the atmosphere from these activities are far below

concentrations which could harm coastal and marine birds.

Accidents: An oil spill would cause localized, low

- level petroleum hydrocarbon contamination. However, it is unlikely that an oil spill would oc cur from the proposed activities (refer to Item 5

, Water Q uality). Marine and pelagic birds feeding at the spill location may experience chronic, nonfatal, physiological stress. It is expected that few, if any, coastal and marine birds would actually be affected to that extent. The activities proposed in this plan will be covered by Apache’s Regional OSRP (refer to information submitted in Section H ).

Discarded trash and debris : Marine and pelagic birds could become entangled and snared in

discarded tr ash and debris, or ingest small plastic debris, which can cause permanent injuries and death. Operators are prohibited from deliberately discharging debris as mandated by MARPOL

Annex V and the Marine Plastic Pollution Research and Control Act, and regula tions imposed byvarious agencies including the United States Coast Guard (USCG) and the Environmental

Protection Agency (EPA). Apache will operate in accordance with the regulations and also avoid accidental loss of solid waste items by maintaining waste management plans, manifesting trash sent to shore, and using special precautions such as covering outside trash bins to prevent

ac cidental loss of solid waste. Special caution will be exercised when handling and disposing of small items and packaging mate rials, particularly those made of non

- biodegradable, environmentally persistent materials such as plastic or glass. Informational placards will be posted on all vessels and facilities having sleeping or food preparation capabilities. All offshore

personne l, including contractors and other support services

- related personnel (e.g. helicopter pilots, vessel captains and boat crews) will be indoctrinated on waste procedures, and will v iew

the video (or Microsoft PowerPoint presentation)

, “Think About It” ( prev iously “All Washed Up: The Beach Litter Problem” ). Thereafter, all personnel will view the marine trash and debris training video annually. Offshore personnel will also receive an explanation from Apache management or the designated lease operator managem ent that emphasizes their commitment to waste management in accordance with NTL No. 2012

- G01

. Debris, if any, from these proposed

activities will seldom interact wit h marine and pelagic birds; therefore, the effects will be negligible.

There are no other IPFs (including effluents, physical disturbances to the seafloor, or wastes sent to shore for treatment or disposal) from the proposed activities which could impact marine and pelagic birds.

3. Public H ealth and S afety D ue to A ccidents.

There are no IPFs (emissions, effluents, physical disturbances to the seafloor, wastes sent to shore for treatment or disposal or accidents, including an accidental H2S releases) from the proposed activities which could cause impacts to public health and safety. In accord ance with

NTL No.’s 2008

- G 04, 2009

- G27

, and 2009

- G31, sufficient information is included in Section D to justify our request that our proposed activities be classified by BSEE as H 2 S absent.

Coastal and Onshore

1. Beaches

IPFs from the proposed activit ies that could cause impacts to beaches include accidents (oil spills) and discarded trash and debris.

Accidents: Oil spills contacting beaches would have impacts on the use of recreational beaches

and associated resources. Due to the distance from sh ore ( 50 miles) and the response capabilities that would be implemented, no significant adverse impacts are expected. The activities proposed in this plan will be covered by Apache’s Regional OSRP (refer to information submitted in

Section H ).Discarded trash and debris: Trash on the beach is recognized as a major threat to the

enjoyment and use of beaches. There will only be a limited amount of marine debris, if any, resulting from the proposed activities. Operators are prohibited from deliberately d ischarging debris as mandated by MARPOL

- Annex V and the Marine Plastic Pollution Research and Control Act, and regulations imposed by various agencies including the United States Coast
Guard (USCG) and the Environm ental Protection Agency (EPA). Apache will operate in accordance with the regulations and also avoid accidental loss of solid waste items by maintaining waste management plans, manifesting trash sent to shore, and using special precautions such as covering outside trash bins to prevent ac cidental loss of solid waste. Special caution will be exercised when handling and disposing of small items and packaging materials, particularly those made of non

- biodegradable, environmentally persistent materials such as plastic or glass.

Informational placard s will be posted on all vessels and facilities having sleeping or food preparation capabilities. All offshore personnel, including contractors and other support

services

- related personnel (e.g. helicopter pilots, vessel captains and boat crews) will be

in doctrinated on waste procedures, and will view the video (or Microsoft PowerPoint presentation)

, “Think About It” ( previously “All Washed Up: The Beach Litter Problem” ). Thereafter, all personnel will view the marine trash and debris training video annuall y. Offshore personnel will also receive an explanation from Apache management or the designated lease operator management that emphasizes their commitment to waste management in accordance

with NTL No. 2012

- G01

.

There are no other IPFs (emissions, efflue nts, physical disturbances to the seafloor, or wastes sent to shore for treatment or disposal) from the proposed activities which could impact beaches.

2. Wetlands

IPFs from the proposed activities that could cause impacts to wetlands include accidents (oil spills) and discarded trash and debris.

Accidents: It is unlikely that an oil spill would occur from the proposed activities (refer to Item

5 , Water Quality). Due to the distance from shore ( 50 miles) and the response capabilities that would be implemented, no impacts are expected. The activities proposed in this plan will be covered by Apache’s Regional OSRP (refer to information submitted in Section H ).

Dis carded trash and debris: There will only be a limited amount of marine debris, if any, resulting from the proposed activities. Operators are prohibited from deliberately discharging debris as mandated by MARPOL

Apache will operate in accordance with the regulations and also avoid accidental loss of solid waste items by maintaining waste management plans, manifesting trash sent to shore, and using special precautions such as covering outside trash bins to prevent accidental loss of solid waste. Specialcaution will be exercised when handling and disposing of small items and packaging materials,

particularly those made of non

- biodegradable, environmentally persistent materials such as plastic or glass.

Informational placards will be posted on all vessels and facilities having sleeping or food preparation capabilities. All offshore personnel, including contractors and other support

services

- related personnel (e.g. helicopter pilots, vessel captains and boat crews) will be indoctrinated on waste procedures, and will view the video (or Microsoft PowerPoint

.

There are no other IPFs (emissions, effluents, physical disturbances to the seafloor, or wastes

sent to shore for treatment or disposal) from the proposed activities which could impact

wetlands.

3. Shore B irds and C oastal N esting B irds

Accidents: Oil spills could cause impacts to shore birds and coastal nesting birds. However, it is unlikely that an oil spill would occur from the proposed activities (refer to Item 5 , Water Q uality). Given the distance from shore ( 50 miles) and the response capabilities that would be implemented, no impacts are expected. The activities proposed in this plan will be covered by Apache’s Region

al OSRP (refer to information submitted in Section H ).

Discarded trash and debris: Coastal and marine birds are highly susceptible to entanglement in floating, submerged, and beached marine debris: specifically plastics. Operators are prohibited

from d eliberately discharging debris as mandated by MARPOL

- Annex V and the Marine Plastic Pollution Research and Control Act, and regulations imposed by various agencies including the United States Coast Guard (USCG) and the Environmental Protection Agency (EPA)

. Apache will operate in accordance with the regulations and also avoid accidental loss of solid waste items by maintaining waste management plans, manifesting trash sent to shore, and using special precautions such as covering outside trash bins to preve nt accidental loss of solid waste. Special caution will be exercised when handling and disposing of small items and packaging materials, particularly those made of non

- biodegradable, environmentally persistent materials such as plastic or glass.

Inform ational placards will be posted on vessels and every facility that has sleeping or food preparation capabilities. All offshore personnel, including contractors and other support

services

- related personnel (e.g. helicopter pilots, vessel captains and boat crews) will be indoctrinated on waste procedures, and will view the video (or Microsoft PowerPoint presentation)

6. Other En vi ronmental Resources Identified

There are no other environmental resources identified for this impact assessment.

(C) IMPAC TS ON PROPOSED ACTIV ITIES

The site

– specific environmental conditions have been taken into account for the proposed

activities. No impacts are expected on the proposed activities from site

- specific environmental

conditions.

(D) ENVIRONMENTAL HAZARD S

During the hurricane season, June through November, the Gulf of Mexico is impacted by an average of ten tropical storms (39

- 73 mph winds ), of which six become hurricanes ( > 74 mph winds) . Due to its location in the gulf, Mississippi Canyon Block 554 and 555 may experience hurricane and tropical storm force winds, and related sea currents. These factors can adversely impact the integrity o

f the operations covered by this plan. A significant storm may present physical hazards to operators and vessels, damage exploration or production equipment, or resultin the release of hazardous materials (including hydrocarbons). Additionally, the displa cement of

equipment may disrupt the local benthic habitat and pose a threat to local species.

The following preventative measures included in this plan may be implemented to mitigate these impacts:

1. Drilling & completion

a. Secure well

b. Secure rig / platform

c. Evacuate personnel

Drilling activities will be conducted in accordance with NTL No.’s 2008

- G09, 2009

- G10 , and

2010

- N10

.

2. Structure Installation Operator will not conduct structure installation operations during Tropical Storm or

Hurricane threat.

( E ) A LTERNATIVES

No alternatives to the proposed activities were considered to reduce environmental impacts.

( F ) MITIGATION M EASURES

No mitigation measures other than those required by regulation will be employed to avoid, diminish, or eliminate potential impa cts on environmental resources.

( G ) CONSULTATION

No agencies or persons were consulted regarding potential impacts associated with the proposed activities. Therefore, a list of such entities has not been provided.
