The heavy equipment and camp were mobilized to Challenge Island alongside the existing Savant and ExxonMobil ice roads on March 4th and 5th, 2009. At completion of camp rig up and the arrival of BP oversight personnel on March 6th the actual pre job safety and excavation program was conducted with all personnel in attendance. A marker indicating original ground level was attached to the CI#1 marker post. The initial excavation was to about 1' of depth below island gravel level where soil samples were obtained from a 5 point quadrant. The diameter of the excavation was near 40'. Excavation continued until about 2' below original ground level where the top of the cellar was located and identified. Based on photos from previous site visits the top of the cellar is at 1' above sea level, therefore original ground level and marker on the post is at 3' above sea level. Excavation continued around the cellar until about 5' of the cellar was exposed. At this time the cellar steel was sheared to allow removal of the steel and cement from inside the cellar to that depth (this equates to approx. 4' below sea level). The marker post was left in place as a depth reference guide. Excavation around the cellar continued to nearly 11' below sea level (14' below island ground level) where seawater intrusion was noted at 2.5' to 3' below the estimated mud line depth. Samples were recovered and the cellar and its contained cement were removed to this depth. The marker post was observed to be unstable and did fall to the edge of the pit giving indication we were at the depth of the original well cutoff and welded plate on the 13-3/8" casing. The central area of the excavation was then cleared to expose the original well welded plate for placement of a new operator and well identifier plate which was welded directly to the old plate. Per request of the DNR the excavation was left open but the excavated cuttings from outside the cellar were arranged as a barrier wall fully around the excavation. No hydrocarbons were detected in the sampling program. Notification to the slope AOGCC inspector (Lou Grimaldi) was made to invite him to witness the site should he choose. At that time no site visit was requested. The cellar cement and steel was transported to Deadhorse for disposal, all equipment and the camp were demobilized back to Deadhorse concluding on March 12th, 2009. • • • • ~.~ .~ `` .+,,, ., t - _ 1. `l: <. ~ `'+... . t. ~ • x ~ ;:: ~~ _ _,. _, ~Y' yy~ r.

From our conversation, I understand that you hope to start mobilization toward the weekend; weather allowing. I checked the regulations in effect when the well work was actually completed and I did not find any depth specification for cutoff. As of 1986 the depth requirement was 2' BML and in 1999 the depth requirement was changed to 5' BML. I understand the difficulties that are involved with the proposed work at Challenge Island. BML is needed for the cutoff, however if 5' is not attainabie then it is acceptable to cutoff shallower however as deep as practicable. Please stay in contact as the work proceeds. A copy of this message should be available at the work site. I have copied the Inspectors. Tom Maunder, PE AOGCC From: Smith, James E [mailto:James.E.Smith@bp.com] Sent: Wednesday, March 04, 2009 8:38 AM To: Maunder, Thomas E (DOA) Cc: Srock, Wade L; Cismoski, Doug A; Rossberg, R Steven; Dunham, Don J (ANC) Subject: RE: Challenge Is. #1 (180-090) works under Sundry #308-138 Tom, In followup to our conversation this morning (3/4/09) I have summarized the key points from that discussion: 1. We are in the process of mobilizing the camp and equipment to perform the cellar and marker post removal from the Challenge Island #1 P&A well (AOGCC permit #180-090). 2. We learned last year that seawater influx into the excavation is a real possibility which may force the use of underwater divers to accomplish the cellar and post cutoff at 5' below the mudline. That depth is 13' below island ground level, the mudline itself is at 8' below island ground level. We have sourced alternative measures to allow removal of seawater influx but are still unsure that we will be granted EPA permits to allow dewatering to remove inflow liquids from the excavation. 3. We propose to attempt the final cutoff of the cellar and marker post at the 5' below mudline depth by cutting the cellar and marker post in stages of several feet per increment on the way down to the 5' below mudline depth. This is consistant with our intial proposal. 3/30/2009 Page 2 of 2 i 4. Should flooding of the excavation force the use of measures with inherent hazards (divers or other underwater work} to reach 5' below mudline we request your concurrence that cutoff at any obtainable depth below the mudline would be acceptable to the AOGCC as a minimum. It is our intention to perform this remediation work in a safe and environmentally sound manner to provide finalization to the Challenge Island #1 P&A well.

The workscope is described under approved Sundry #308-138 (approved 4/17/2008). The workscope of the Challenge Island #1 Remediation included deferral of the remediation should seawater influx force the need to use underwater divers or alternate methods to cut the cellar and marker post for removal. A test hole drilled April 26, 2008 did indicate that seawater was present at a depth that would force the use of divers or fluids removal. BP elected at that time to defer the work until the winter of 2008-2009 to allow adequate preparations for high risk diving operations and/or fluids handling. We have prepared the necessary safety and environmental safeguards for underwater work and are now in a position to continue the remediation. We currently estimate that this work will resume in March, 2009 (weather permitting). Your north slope AOGCC inspectors will be notified to witness the cutoff should they choose. Photos will be taken to document the cutoff completion, soil samples will be collected (per ADNR) and the excavation will not be backfilled (per the Corp. of Engineers). Any changes to this program plan will be promptly submitted to the AOGCC. Regards, James E.

Challenge Island #1 Well Cellar Removal Project. ~~:r~~~~~ MAY ~ ~ 2008 Dear Mrs. Foerster: BP Exploration (Alaska) Inc. transported a small shot-hole drilling auger to the Challenge Island #1 location on April 26, 2008 to drill a shallow test hole adjacent to the existing well cellar to confirm whether unfrozen sea water may be encountered during subsequent excavation of the cellar and marker post. Free seawater was encountered prior to the desired excavation depth below the island surface (water at 14-1/2', desired excavation depth was to be at least 15'). That water level rose and stabilized at 11-1/2' of depth below the island surface. Plans in place for the potential entrance of seawater mandated that a deferral of the project would be necessary to adequately prepare for the safe application of underwater divers and underwater operations to remove the cellar and marker post. Beginning in August, 2008 the BP planning team will reconvene to restart permitting, planning and crew training to allow removal of the Challenge Island #1 marker post and cellar. The proposed initiation of the actual excavation and removal operations with divers is estimated to be February, 2009 when equipment can be mobilized over ice to the well site. The estimated duration for removal efforts is still estimated at two weeks and would again follow the program outlined in the Sundry form #308-138 for this work with just the addition of divers for underwater cutoff of the cellar and marker post. If you have any questions or require additional information, please contact me at 907- 564-4194. Sincerely, Harold R.

The investigation for sea water was described as Phase III of the work plan. According to the sundry application (page 2, section 2.2, last sentence}, "The findings of the drilling investigation and recommendations for proceeding to Phase IV (Well Cellar and Marker Post Removal) will be presented in a short fetter report." I don't remember seeing any short report. Do you know if something has been submitted? By my read of the attachment to the sundry, sundry 308-138 authorizes the removal of the cellar and marker post so no additional approval should be necessary. I would suspect that the recommendations in the "short report" would cover potential changes to the proposed procedure due the Phase III findings. I hope this helps.

Subject: Challenge Island Well Cellar Removal Update All, On Saturday April 26, 2008 BPXA completed (via helicopter access) the test hole drilling component of the Challenge Island #1 well cellar removal program. The test hole was drilled to the target depth of 15'. At 14.5' seawater inflow was detected, that flow continued and filled the hole to a depth of 11.5' within 15 minutes and remained near static at that depth. Per program, BPXA is deferring cellar removal efforts until this coming winter when diving crews and underwater operations can be evaluated and accomplished if needed. Thank you for your quick turnaround with regards to the Challenge Island well cellar removal project. 1 will be in contact later this year as the 2008-09 winter season approaches.

Challenge Island #1 Project Phase III and IV Well Cellar Removal Operations Program 1. Project Background and Objectives BP has requested Fairweather E&P Services, Inc. to remove the cellar and marker post from the Challenge Island #1 well (CI#1) which was plugged and abandoned in 1981. The need for this work arose from an August 2007 flyover of the well location that revealed that Challenge Island had naturally shifted and the well was now in open water approximately 25 feet north of the island. Figure 1 shows the well location during August 2007. The cellar removal program consists of four (4) phases: reconnaissance trip to the well; permitting and planning; investigation of seawater presence; and the well cellar and marker post removal operations. Fairweather performed the Phase I site reconnaissance trio on January 30, 2008. The results of that investigation revealed that the island has been naturally replenished with gravel around the well where there is approximately 145f feet of gravel on both the north and south sides of the island and the well is essentially in the middle of the island from a north/south perspective (see Figure 2). The well cellar and marker post are all that is currently present on the surface of Challenge Island with the top of the well cellar just 3 inches below the level of the gravel island. Water depth is estimated at 9 feet deep on the north side at the toe of the island and 5 feet deep in the lagoon on the south side of the island, thus establishing a declination line difference of approximately 4 feet from the lagoon to the north side of the island. Based on this information, the location of the well indicates a mud line depth of approximately 7 feet below sea level or 8 . feet below island level. Island level is 1 foot above sea level in the vicinity of the well. AOGCC regulations require a cut off depth of 5 feet below mud line which indicates a cellar and marker post cut off point of approximately 13 feet below island level to comply with the regulations. Phase II of the project, Permitting and Planning, will be completed prior to commencement of field operations. Permits for the project will include the following: Agency PermitlAutharization AOGCC Sundry Notice, Form 10-403 ADNR Land Use Permit (existing BP permit) USACE Nationwide Permit 22, Removal of Vessels North Slope Borough Administrative Approval USFWS Letter of Authorization for the Taking of Polar Bears 2. Phase III: Drilling to Perform Seawater Investigation Prior to removal of the CI#1 well cellar and marker post, a drilling investigation will be completed near the well cellar to determine if sea water incursion is present at the proposed cut off depth. The drilling investigation activities are detailed below. • • 2.1 Phase III Mobilization The drill rig and personnel will be transported to the CI#1 site via helicopter. Drilling. is not expected to exceed one day. Personnel and equipment for this phase of the project will include: Personnel: 1 ea Supervisor/polar bear watch 1 ea Driller 1 ea Drill helper 2 ea Helicopter pilots Equipment: Mobile B-24 drill rig 3.5-inch diameter solid flight auger and drilling tools Emergency supply kit Communications: Cellular and satellite telephone 2.2 Drilling Investigation Prior to Phase IV work taking place a test boring will be drilled immediately adjacent to the CI#1 well cellar to determine if seawater intrusion is likely to be present at the proposed cut off depth. Because the known mud line is at approximately 8 feet below the island surface and AOGCC regulations require a cut off depth of 5 feet below mud line, the investigation boring will be advanced to approximately 15 feet below the island surface to determine if seawater is present. No soil or water sampling is planned. The intrusion of seawater will be determined by examining the drill auger for saturated soil conditions, lead line, or looking down the auger hole with a flashlight if the hole will stay open. The findings of the drilling investigation and recommendations for proceeding to Phase IV (Well Cellaz and Marker Post Removal) will be presented in a short letter report. 3. Phase IV: Well Cellar and Marker Post Removal Operations Plan Removal of the CI#1 well cellar and mazker post to the required depth may require several different methods for removal depending on the results of the Phase III Investigation and whether seawater is present at or above the cutoff depth. Two removal scenarios are detailed in the following sections. 3.1 Safety The field crew will place the highest priority on safety and will continually re-evaluate the safety aspects of the job as variable working conditions are encountered in the field. A safety plan is also available for this project. 2 • Potential subcontractors to Fairweather for the work program include Offshore Divers of Anchorage, Alaska and Cruz Construction of Palmer, Alaska. Cruz Construction will provide logistical support for the project (either Scenario 1 or 2). Offshore Divers will provide diving support if sea water intrusion is discovered (Scenario 2) during the Phase III drilling investigation. Both of these companies have excellent safety records and have worked extensively with Fairweather on previous projects and are well qualified to assist Fairweather in the project execution. 3.2 Phase IV Mobilization Necessary equipment, personnel and the minimum 1S man camp will be transported to the CI#1 site via all terrain vehicles and trailers from Deadhorse. Figure 3 shows the sea ice travel route from the Endicott causeway to Challenge Island. Personnel will travel to the to 'on by all terrain vehicle and helicopter. The camp will be located on the , ~~'~ ~ ~ ~ $~I just s~ of the CI#1 location. Personnel and equipment for the project under Scenario 1 will include the following: Personnel: 1 ea 1 ea 1 ea 1 ea 1 ea 1 ea Working foreman Mechanic/welder Equipment operator Roustabout Polar bear watch Cook Equipment: 1 ea 1 S man camp 2 ea All terrain travel vehicles and trailers 1 ea Volvo L120 loader or equivalent 1 ea Hitachi EX 4S0 excavator or Hitachi 200 excavator 3 ea Heaters 2 ea Light plants 1 ea Fresh water tank/snow melter 1 ea Double wall fuel tank 1 ea Spill kit 1 ea Shop with welding machine and tools 1 ea Air compressor 1 ea Pneumatic reciprocating saw 1 ea Harness assemblies for non-hazardous confined space entry Communications: Cellular and satellite telephone Under Scenario 2 (seawater intrusion present) the following additional personnel and equipment would be needed: Personnel: Sea Dive crew Equipment: 1 ea Shallow dive spread with underwater cutting capability • • 1 ea Heated connex for dive support 3.3 Well Cellar and Marker Post Removal Scenarios Scenario 1: No Seawater Intrusion at or Above Cutoff Depth 1. Rig excavator with a hydraulic hammer to chip up the interior contents of the cellar to 5 feet below grade. Remove the hammer and switch to the excavator bucket and remove chipped cellaz contents and set aside in same cuttings bin for G&I disposal. 2. Excavate gravel from around the cellar to 6 feet below grade. Slope the sidewalls as necessary to comply with OSHA requirements for slope stability for given excavation material. The excavation will be treated as a non hazardous confined space and will be vented with indirect fired forced air heaters. Cut away sections of the cellaz at 5 feet below grade with cutting torches or pneumatic saw to remove the top 5 feet of cellar. Cutoff marker post at 5 feet below grade as well. Set scrap steel aside in steel dumpster for backhaul. 4. Repeat steps one through three above until cellar and well marker post is cut off to program depth of 13 feet below island level. 5. Weld a steel marker plate on the well casings, if necessary. A steel plate currently '~ exists on top of the casings. ~ ~~~~~ s~.ov~~ ~~ ~~~~ ~~ ~ r p~t~.

Clean up location, backhaul debris and demobilize camp and all equipment. Scenario 2: Seawater Intrusion Present at or Above Cutoff Depth 1. With the presence of water intrusion into the cellar area during excavation, a 5 man dive team will be mobilized to the location. 2. A portion of the top of the cellar and well marker post may be cut off using the techniques discussed above in Scenario 1 depending upon what depth water intrusion begins. Removal techniques described below assume seawater has entered the excavation to sea level. 3. Rig excavator with a hydraulic hammer to chip up the interior contents of the cellaz to 5 feet below grade. Switch to excavator bucket and remove chipped cellaz contents and set aside in cuttings bin for G&I disposal. Repeat this process 4 • • until cellar contents are removed from the interior of the cellar to at least 2 feet below the program cutoff depth. 4. Approximately SO% of the external wall of the cellar will be excavated to approximately 2 to 4 feet below the cut off elevation. This excavation will be sloped 3:1 for diver safety. S. A quarter of the cellar circumference will be cut by the diver at the cut off elevation. Four inches will be left uncut at each end and middle of the circumferential cut. The cellar wall then will be cut vertically from the bottom to the top leaving four inches uncut on each side at the center and the top. At the completion of the vertical cuts the excavator will be used to break off uncut hangers and remove the section of cellar wall. 6. The excavator will excavate a new section of the cellar wall at a 3:1 slope and the quarter wall section removal procedure will be repeated. 7. At the completion of the cellar wall removal, the marker post and any casings that extend above the cutoff depth will be removed. 8. a ..,.,,.. ~w,,.,,. Do NoT B¢c~cF/~ - P.~¢ co~° of ~->ti~s, ~~ 9. Clean up location, backhaul debris and demobilize all equipment. At the completion of operations and demobilization, reports will be prepared to document the well cellar removal operations for agencies such as the North Slope Borough, AOGCC and ADNR 4. Waste Management The contents of the well cellar will be removed and backhauled to CC2A or other G&I disposal location designated by BP. Other solid waste debris created during activities associated with the site work will be backhauled to an ADEC-approved solid waste disposal facility. Food wastes will be containerized and stored inside the camp facility to prevent the attraction of wildlife. Food and other solid wastes will be transported to Prudhoe Bay for disposal in conjunction with other project support trips. Camp gray water will be discharged to a holding tank that will be transported back to Prudhoe Bay for gray water disposal. Pacto toilets in the camp will eliminate blackwater disposal needs. 3. Water Use Camp water will be supplied by a snow melter thus eliminating the need for freshwater from sources onshore. Drinking water will be bottled water. • 6. Wildlife Issues The usual wildlife that could be in the area during the winter includes owls, ravens, seals, arctic foxes, and polar bears. A Polar Bear and Wildlife Interaction Plan has been prepared for the project and will be reviewed by all project personnel prior to conducting field operations. 7. Oil Spill Response ' Onsite volumes will be less than 10,000 gallons of diesel and all tanks will be double walled tanks in a containment area or on mobile sources such as sleds. Fuel transfer procedures will be followed to minimize the potential for any spills. These practices will include two person fueling operations to watch tank levels while fueling, use of drip pans under connections, twice dail inspection of fuel tanks and daily fuel use tallies. 14GL ~/~ic~ s w/~ f~ S,~' ~9•~'GRra=rte rq~ovc~ B~• ~iJ 8. Historical, Archaeological and Cultural Resources I Cultural resources are not anticipated to be encountered on the project as all access to the site will be by the North Slope gravel road system and sea ice trail. The Challenge Island site itself is a highly dynamic marine environment with continual removal and depositing of sediments occurring on an annual basis and only the area immediate to the well will be excavated. Therefore, no cultural resources are anticipated to be impacted by the project activities. 6 • Figure 1.

The May 18t" letter concerned the condition of certain Pt. Thomson Unit wells. Your letter concerns the abandoned Challenge Island # 1 well, which was operated by BP Exploration (Alaska), Inc,'s ("BPXA") predecessor SOHIO Alaska Petroleum Company. The island where the well is located has physically shifted in the twenty-six years since the well was abandoned. Now, the well's abandonment marker and a portion of its cellar are awash. Your letter states that you plan to accomplish intervention work on the remaining structure of the Challenge Island # 1 well during the 2008 - 2009 winter season. Please remember that the actual work plan needs to be submitted (on Form 10-403) to the Commission for approval. We appreciate BPXA's responsiveness to the Commission's concerns regarding the abandoned Challenge Island #1 well.

The AOGCC requested information on these wells by November 14, 2007. Please note that the Challenge Island #1 was operated by our heritage company, SOHIO Alaska Petroleum Company, and the well was not a part of the Point Thomson Unit. We request that all future correspondence related to the condition of this abandoned well be directed to BP Exploration (Alaska}, lnc. (BP). Our records indicate that in 1981 the well was plugged and abandoned in accordance with then current AOGCC regulations. An AOGCC inspector witnessed the plugging and abandonment operations and the AOGCC issued location clearance. Documentation supporting our compliance with AOGCC regulations then in effect is located in AOGCC's online database under Document Name: 180-090. We recently learned that subsequent to 1981, Challenge Island physically shifted as a result of local environmental conditions, and the abandoned well site is now located slightly offshore beyond the inter-tidal zone of the island. Consequently a portion of the well cellar and the vertical well marker are visible above the water surface (see attached photo}. We have advised the United States Coast Guard, United States Army Corp of Engineers and Alaska Department of Natural Resources. BP ~xplcsratian (Alaska) Inc. Although we believe that BP has complied with its legal obligations w€th regard to the abandonment of this well, we nevertheless appreciate the AOGCC's concerns, and we have decided to assist the State in this matter. Accordingly, we are developing an intervention plan, and we anticipate obtaining approval of this plan soon from the other parties who formerly owned an interest in this well. We will then submit a detailed intervention plan and request appropriate approval from the AOGCC. We anticipate performing the intervention in the winter of 2008-09.

The Review Procedure The ~uahtanve risk screening procedure reqmred m the above referenced document determines whether a s~te presents neghg~ble levels of risk. or ~f it ~s a s~gruficant risk generator A decision scheme ~s then employed to establish t l) whether or not there ~s a Mr. Steven D.

The first step in this screenlng criteria ~s establishing a Dasls of concern' "If the waste site has released contaminants or there are mechanism for r~otenuai releases and there are receptors nearby, then. there may be cause for concern, and the waste site should be studied further.' and "If there :s no release of contamination or no mechanisms for potenual releases and there are no recer~tors nearby, then there ~s not a bas~s for concern and the x,.aste s~te should be considered c:osea." The criteria that are measured at a ~xaste site to satlsfx tae above logical arguments are: Evidence of release of chem~ca! contamlnauon at the waste site In excess of Alaska Water Quality Standards for one or more target comr>ounds, or Mechanism for potential release, and Proximity of the waste sire to biolomcai recentors. If either of the first two criteria and the last criteria are met. there Is a basis for concern, and before proceeding w~th Step 2. a corrective action plan shall be prepared for the site which shall ~dentffy alternative wavs to correct or m~tigate the basis of concern, r~revent its recurrence, and select a preferred approach. Correct,ye acuon alternatives shall be described at a conceptual level, and the select,on of a prefer'rea approach shall be based on balancing protecuveness with implementablht.,, and cost-effectiveness. The second step determines whether contamination at a waste site present a risk to receptors that ~s s~gnificant. If risk is found not to be significant, it is considered to be "negligible." The finding or'-s_igruficant risk is based on the likelihood of exposure and the Irkelihood of adverse consequences of exposure' "For r~sk to be considered sigmficant, the receptors must be vulnerable to exposure, and the consequences of exposure must be 'adverse to human or ammal health or the environment." and. conversely. "If exposure is unlrkel;' or the consequences of exposure are not 'adverse.' then the risk is negligible. *Ir Eteven D Taylor January '_2. 1995 BPXA inacuve Dnii',n__~ Waste Disposal Facmtv.

Sec. 8, T10N, R12E, UPM. March 11.? 1981 I left Anchorage at 9:15 AM by a SOHIO charter, A'~a'ska A~rli'n'es, to Prudhoe Bay arriving at 10:45 AM. I left Prudhoe by SOHIO's chartered CASA 212 and arrived at Challenge Island at 11:30 AM. I witnessed the plugging and abandonment of Challenge Island No. I from March 11, 1981 to March 16, 1981. The SOHIO super- visor was Bill Struble. Work consisted of the following= EZ dx~tl a't 5424' w/100 sack cap, raged plug~ EZ drill at 3516' w/100 sack cap~ EZ drill at 2740' w/100 sack cap, tagged plug~ Cement plug from 55' below ground level to bottom of cellar~ Welded plate on top of 13 3/8= and installed marker post with required data. March 12, 1981 The cement was not set up on the plug set above '%he EZ drill at 2740'. The bit went all the way down to the EZ drill. I informed Bill Struble the cement had to be circulated out and another plug set. This was done and the next plug was set at 2410t and was tagged with 50,000 pound for 10 minutes with no loss on weight indicator. I made a sketch and recorded the data concerning the plugging of this well. In summary~ I witnessed the plugging and abandonment of Challenge Island No. 1.

Dick Judd called to review their present situation and their abandonment program. They have perforated the drill pipe twice and have placed two separate cement plugs. Following the second plug the drill pipe was pressured to 1500 psi and held. There is zero pressure now at the surface on the drill pipe and annulus. They attempted to perforate the drill pipe at 8054'/ 8061' and did not get penetration. They are preparing to try again to perforate this interval. When they get the drill pipe perforated they plan to pump in a 20 sax cement plug. They will try and balance this plug to give them 265' of fill in and outside of the drill pipe. They will then try to backoff and recover the drill pipe above this plug. They want to check the integrity of the casing above the last plug before any more plugs are set. I gave him verbal approval on this procedure.
