There was no wellhead associated with this well.The casing conductor string was 7"and is set at a depth of approximately 52'.There was 708'of 2-1/2"tubing in the hole. Operations Summary: OCS began the rig up on location on 07/29/2016. This was to be a summer time operation meaning there was no snow pack and/or ice pack to use for the base of location.The use enviro-mats were used to build the base of location above the tundra surrounding the wellhead.All well work equipment was spotted into place to include a cement&pumping unit, steam boiler,fresh water conex,2 closed loop system pits,and extenda boom forklift.A work table/floor was constructed on and above the existing 7"casing using a 7"riser extension. Thawing operations inside of the tubing began on 8/02/2016 and continued to a depth of 18'below ground level at which time the workstring was unable to pass through the tubing any deeper. It is inferred that the 2-7/8"was collapsed from an inadequate freeze protection earlier in the well's life. It was approved to move forward with the plugging operations to cement through the tubing work string at this depth. The tubing workstring was left in the hole and tied back at surface using a keyhole engineered into the work platform. Thawing operations began in the IA and continued to a depth of 41'below ground level. A hard spot was noted at 41'and the workstring was unable to penetrate any deeper. Approval was given to use the 41'as the base depth for this P&A,and progress resumed. Preparations were made and the well was rigged up to be cemented using a workstring down both annuli. A cement head at the surface was rigged up from the cement pump to selectively divert cement to one annuli or another. A total of 2 bbls of cement were pumped down the tubing first,then 3 bbls of cement were pumped down the IA workstring and cement returns were observed at surface.Final cement in place was completed on the same day(8/02/2016).The workstrings were pulled from the wellbore per the pre-project procedure.The workstrings pulled full of hardened cement.The well riser and work table were removed,and a small void in the tubing from the workstring being pulled was observed. On 8/03/2016 a small top job was performed top filling the void with a total of 1.5 gallons of 14.9 ppg cement.The surface equipment was rigged down and removed from location,then the matting boards and supports removed. The 7" casing was cut off and capped with an API marker plate on 8/21/2016 leaving the top of the casing over 3'below original ground level. The well cellar area was back filled with fresh fill and all surface debris were cleaned from location.

Some of these wells require extensive cleanup of oil and other hazardous substances released to the environment. Since you are identified as a current or past owner and/or operator of these sites, please be advised you may be financially responsible or liable for the investigation and /or cleanup of any hazardous substance contamination that might be present. Alaska Statute 46.03.822 establishes who is liable for contamination. Records available to the ADEC indicate that you meet one or more of the following criteria: » owned or controlled the hazardous substance at the time of its release; » own(ed) or operate(d) the property or facility from which the release occurred; » owned or operated property at which the hazardous substance came to be located; and » arranged for transport, disposal or treatment of hazardous substances that were released. Site History From 1944 through 1982 the US Government drilled 136 wells to explore for oil and gas resources in the NPRA. It is our understanding that other federal agencies and some private companies may have operated or managed these sites in the past. We have also been informed that 23 of these well have been conveyed to public and private entities. The ADEC currently lists 14 of the 136 legacy wells on our database of contaminated sites. The Bureau of Land Management (BLM) is identified as the responsible party for the following sites. Wayne Svejnoha 0 2 February 4, 2014 • BLM Cape Halkett Drill Site (File # 300.38.108) • BLM East Simpson #2 (File # 300.38.109) • BLM East Teshekpuk Drill Site (File # 300.38.110) The U.S. Army Corps of Engineers, under the Formerly Used Defense Sites program, is working with ADEC under the Defense States Memorandum of Agreement on cleanup actions at the 11 Umiat test well sites. BLM is identified as the landowner in our records, and as such is identified as a potentially responsible party in addition to the Department of Defense: C Umiat Test Wells 1-11 (File # 335.38.001) The information contained in these files is part of the public record. Our databases are accessible on the Internet at: http://dec.alaska.gov/spar/csp/db_search.httn Additional Actions Needed ADEC sent a letter on July 11, 2013, identifying an additional 15 legacy well sites with confirmed releases (enclosed). As stated in the letter, ADEC recommends that BLM develop a plan to address known, suspected, and unknown releases at the legacy well sites, in coordination with the appropriate regulatory agencies. We expected a response to this letter before now. Please respond to this letter within 30 days. After we receive and review your response we will determine what additional actions will be taken regarding each site with known or suspected contamination. In addition, with your response, please complete and return the enclosed questionnaire requesting more information about past operators. In accordance with Alaska Statute Title 46, ADEC is authorized to provide regulatory oversight for any contamination response efforts initiated by the responsible party. However, if response actions by the responsible party are not satisfactory to ADEC, we may then assume the lead role in the investigation and cleanup efforts. In the event that State response actions are necessary, the responsible parties may be held financially liable for any response actions taken by the State. Alaska Statutes 46.04.010 and 46.08.070 establish cost recovery procedures for certain costs, including oversight activities, incurred by the State in responding to pollution incidents. If you are determined to be a responsible or liable party, ADEC may bill you at a later date for our expenditures associated with this pollution incident. Expenses for which we may seek reimbursement include: Staff time associated with general or technical assistance; work plan review; project oversight; general project management; legal services; interest; travel; equipment and supplies; and any contracting costs. Pursuant to Alaska Statute 46.08.075, the State may also file liens against all property owned by a person who is responsible or liable for State expenditures. Please respond in writing within thirty (30) days from the date of this letter addressing your intended actions with respect to this pollution incident. If you believe someone else is responsible for this pollution incident (e.g., a past owner or operation of the site) or if you have any questions concerning this matter, please contact Mr. Fred Vreeman at (907) 451-2181. The attached "ADEC Information Request" describes the minimum information expected in your response. Additional information may needed to evaluate the risks and responses required at each legacy well site.

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by ACIGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we arc outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment of the contingency for assessment of known, likely, or unknown but possible contaminant releases. In addition, BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil, gasses, refined oil and fuel, drilling fluids that include various organics, metals, and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the process of being addressed, cleaned up, and closed. From our Waited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites, impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down -hole substances that were ejected from the holes over time or during blowouts or drilling operations. 1 Wayne Sve noha ? July 11, 2013 Y The.BLN-1 plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC — Contaminated Sites, Alaska Oil & Gas Conservation Commission, and ADEC — EH/Solid Waste. Other agencies will need to be consulted. as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re -visited in the fu=e xvhen they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) 'chis is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an Sl is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCL-A and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR, PA, and SI then a RI/FS under CERCLA, or a Site Characte-rizatiowlteportandcleanup-Alas,under-l-fi-AAC7iis`required. -- ----- - -- — --------- - DEC recommends that BLM incorporate into the strategic pian the processes outlined in this letter. A team of agencies composed of AOGC, DEC -CS, EPA as required, and DEC -EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense, and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared, the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi -site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups.

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by AOGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we are outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment or the contingency for assessment of known,likely, or unknown but possible contaminant releases. In addition,BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil,gasses,refined oil and fuel, drilling fluids that include various organics,metals, and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the process of being addressed, cleaned up, and closed. From our limited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites,impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits,continued surface runoff from drilling fluids uncontained at several sites, and down-hole substances that were ejected from the holes over time or during blowouts or drilling operations. , Wayne Svejnoha 2 July 11, 2013 The BLM plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC —Contaminated Sites,Alaska Oil& Gas Conservation Commission, and ADEC—EH/Solid Waste. Other agencies will need to be consulted as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re-visited in the future when they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) This is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an SI is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCLA and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR,PA, and SI then a RI/FS under CERCLA, or a Site Characterization Report and cleanup plan under 18 AAC 75 is required. DEC recommends that BLM incorporate into the strategic plan the processes outlined in this letter. A team of agencies composed of AOGC, DEC-CS, EPA as required,and DEC-EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense,and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared,the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi-site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups. r_\Q13 P\rc\Fo in.,l>;.,r1:i..c\C;.r1■.,,RPrir..1 Aornriec\nnT\RT.M\Proiects\Legacy Wells\7 11 13 Letter to BLM on Legacy Wells.docx Mayne Svejnoha 3 July 11, 2013 Please review the attached list of specific sites.

The Arcon Barrow Core Test #1 site is approximately 5 miles northeast of downtown Barrow in an area of town referred to as NARL, the former Naval Arctic Research Laboratory, which is accessible from Stevenson Street. The BLM manages the tract of land on which the core test is located and the tract is part of the National Petroleum Reserve in Alaska. The last inspection of the site was July 2012. Site Description: The Arcon Barrow Core Test #1 site consists of open casing located inside a constructed wooden cellar and a small amount of associated scattered surface debris in an area measuring 30 feet north to south by 15 feet east to west [Figure 1]. The U.S. Navy drilled this core test in 1947. There is no pad or reserve pit associated with the core test. Instead of digging a cellar, the U.S. Navy constructed a 5x5 -foot box to use as a mud pit [Figure 2]. This box contains the core test and has grass and other vegetation growing inside of it. There are no visible drilling muds inside this box. One of the large timbers used for rig support is present and the cellar is intact. The immediate area surrounding the core test is largely devoid of garbage, with the exception of some busted cement near the 5x5 -foot box. Surface Risk Assessment: Low.Justification: There are no known contaminants present on the site. Arcon lies about 100 feet from the shoreline of Imikpuk Lake. Erosion from the lake is not likely to have any effect on this core test in the near future, as erosion is very minimal. Imikpuk Lake is a relatively small, shallow -thaw lake with beach deposits and no bluffs or exposed permafrost. The lake does not serve as Barrow's drinking water source due to possible contaminants from gasoline and diesel spills that occurred near the lake in the 1970s (Alaska Department of Environmental Conservation 2012). The site is accessible by residents of Barrow, who travel along Stevenson Street to access seasonal cabins for subsistence use. With the large amount of development and infrastructure near the site that prevents off-road travel, it is unlikely that the site poses a travel risk to local residents [Figure 3]. The BLM will need to prepare a determination of eligibility pursuant to Section 106 of the National Historic Preservation Act, due to the age of the site. If the site is not eligible, then the surface debris should be removed as funding allows or in conjunction with other scheduled operations, if possible.

BLM Open File Report 127 • February 2013 13 Section 2: Wells BLM Monitors • • Legacy Wells Summary Report SUBSURFACE INFORMATION Well Information: • Well History: The U.S. Navy drilled the Arcon Barrow Core Test #1 in 1947 upon completion of the Skull Cliff test well using a Failing 314 -C drill rig. A camp area was created by clearing away vegetation with a bulldozer in order to place temporary infrastructure to support drilling operations. (Note: camp area is currently unidentifiable due to later construction/ improvements by the U.S. Navy at NARL). The drill rig was set up within the camp area to drill for stratigraphic information and experiment with reverse circulation for coring. The rig was set up on 12x12 -foot timbers, 24 inches off the ground. Instead of digging a cellar, a 5x5 -foot box was constructed to use as a mud pit. The core test reached a total depth of 1,442 feet, which was the maximum depth that the rig was capable of drilling safely. • Well Condition: There is no wellhead associated with Arcon #1 [Figure 4]. It has 2 -inch tubing with a water type valve inside a 5% -inch open casing. Both the tubing and the 5 %-inch casing have clamps. The open casing with tubing is approximately 36 inches high. A plumb -bob was dropped downhole and hit solid at 6 feet, likely an ice plug. A little diesel fuel mixed with water is present in the casing between the ice plug and the surface. Grass and other vegetation are growing inside the box that contains the core test. There are no visible drilling muds in the box. • Wellhead Components: None. There is no wellhead at this site. Geologic Setting: The test hole encountered the Gubik, Grandstand, and Topagoruk formations. There were no appreciable shows of oil and gas (Collins and Brewer 1961). Development Potential: Gas development has occurred near this area for several decades. No detrimental effects from the Arcon #1 core test have been observed to date. There are no documented plugs [Figure 5]. The BLM plans to plug this core test within the next three years. Groundwater Resource: None. Continuous permafrost is about 1400 feet thick throughout the entire Barrow region. Fresh water aquifers are not present. Barrow, the closest population center to the Arcon #1 site, gets its drinking water from treated surface water, rather than from aquifers. The active layer measures between 20 to 55 inches (Alaska Department of Environmental Conservation 2012). Other Information: There were no hydrocarbons present on the surface near the core test. 14 BLM Open File Report 127 • February 2013 Legacy Wells Summary Report Section 2: Wells BLM Monitors A .Af efn-8a -tow Core 7es1 #1 D rli . _- 9 7!8" D ole drilled %via Hughes OSQ•7 rock nil 52.7' of 7' casing was cementer) 60.75' w/13 sz of cement A F 7/8' Hughes rock oil was t sed to drill to 100'. r. 4 Failing reverse cirr. here, swivel and drill pipe installed Used lo core from 10C143'.
