The closure applications and corrective action plans provided the required information describing the history and conditions ofthe reserve pits(s), results of required water sampling, an assessment of the potential risks posed by the drilling waste to human health and the environment as well as proposed corrective actions. Corrective actions are completed at the sites. At Gwydry Bay State A-I, all drilling was excavated for disposal by injection. At Plaghm Beechey Point, the below grade reserve pit was capped in place with gravel from the exploration pad. At Placid et aI, additional capping material was placed in a small pool of water associated with the flair pit. Some residual sheening remains at Placid et al. ADEC has determined that these sites present no material or probable risk to the public health or the environment. Public notice requesting comments on the closure requests was published March 7 and 8, 2003 in the Anchorage Daily News and posted on the state web site March 7, 2003. No public comments objecting to closure approval were received in response to this public notice. ADEC has determined that the reserve pits at these sites meet the closure requirements of 18 AAC 60.440. Closure Approval Under authority of 18 AAC 60.440 (j), ADEC grants permanent closure approval to e Mr. Charles E. Terwilliger, Jr. Glenn Springs Holdings Inc. e April 17,2003 Page 2 of3 Glenn Springs Holdings Inc.

First let me say that I think most wells drilled in Alaska in 1973 probably had reserve pits. In reviewing subject file, on the Monthly Report of Drilling and Workover Operations for December 1973, is this entry for the period Dec 1-12, 73 "Construction of drilling pad, reserve pit, and fuel storage area". Further, our inspector reported inspecting the reserve pit on January 11, 1974. On August 14, 1974 our inspector inspected the CSO-Gwyder Bay State "A" No. 1 (S3c.31, T13N, R13E, U.M.) location for final abandonment and concluded "I gave Carl a copy of "Field Inspection Report" indicating the condition of the abandoned location was satisfactory". Judd, there was a reserve pit at subject location. It was abandoned and accepted as satisfactory byu the AOGCC in August 1974. By letter dated September 30,1992 we gave Location Clearance to ARCO for subject well. If you need additional information, please contact me by E-mail or phone 793-1226. Blair Wondzell, 793-1226 or "Peterson, Judd" wrote: Hey Blair, I got a call recently from an oil investor that was interested in purchasing some of the ARCO/Phillips ground that is going to be released. He was inquiring about the status of a City Services site, Gwydry Bay State A #1 drilled in 1974, Permit # 73-0028-0 located in 31-13N, 13E UM. His concern was environmental liability that they might inherit. The site has not been turned into the reserve pit closure program and I can find no information on this site in the ADEC files. From the maps it appears to be on an offshore bar or island. Could you check your file on this well and see it you can tell if there was a reserve pit constructed on the site? I suspect there was not and would like to mark if off my data base as not needing closure if there was no pit. Thanks, Judd Peterson , ~, 6/12/00 12:38 PM CONSERVATION COMMISSION WALTER J.

We flew oveF~the CSO-Gwydyr Bay State "A" lid .... 1 location and it looked clean and smooth.- Bud Helmricks met our chopper.qn his, airstrip (Photo 1). We went to Bud's house where we discussed Arctic operations in general and Bud's life style in particular, while, his wife .put the final touches on dinner'. Bud. showed us how he converts potholes to dry land and obtains soil for his .runway and - other needs. He fills holes-with backhaul debris from location clean-ups, covers the debris with a layer of. dirt and reseeds (Photo 2). After dinner Bob Anderson, Oim Callender, Bill Copeland, Bud Helmricks and his son Jim, and I left by chopper to look.-at the two Union abandoned well sites Kalubik Creek Staging Area -..,.Union hired-Bud. Helmricks to clean, level and reseed the two well sites,~ airstrips and road connecting, the..Ka!ubik Creek . No. I location to the staging area ~wo miles.to the north.. All_~of the above were constructed with built, up ice .and snow,.--without gravel. : -:- -- .,~ Bill Copeland and Bob Anderson were primarily interested in th'e road and airstrips while the main concern-of Jim Callender .amd myself was the. well sites. We flew over the staging area. at the mouth o~.~the Kalubik River. The Homer L. Burrell -2- August 29, 1974 Wodeco rig which 'drilled the Kalubik Creek No. I was still stacked there. (Photo 3). Jim said that in 1970 this was one of the most complete rigs on the slope. Since then it has been cannibalized anti flooded once. Also, new drilling rigs of comparable depth capacity weigh much less and ~equire 1/3 the rig-up or rig-down time. As a result, even with the shortage of rigs on the slope, there are no known plans to use this one. We flew along the two mile road to the Union-Kaiubik Creek No. I abandoned location and airstrip. The. old ice road had been reseeded and was mostly revegetated. Union-Xalubik Creek No. 1 (.Sec. 10..,. T12N, RSE, U.M.) - ~I? landed near the abandoned well marker, Which l's'a 'j(~i'~i~'6f '9-5/~1'-- casing cemented in the hole and extending approximately 10' above ground level {Photo-4). The proper well information was. bead welded on the pipe. The well was P&A 3/27/70. The area was very clean and level {Photo 5). After cutting off about 240 pilings 3' below ground level (l' below permafrost top) and level- ing, the entire area was fertilized and reseeded with a mixture of native and domestic grasses recommended by a University of Alaska research team. The reseeding and natural encroachment has been very effective. It appears that the disturbed area will look like the surrounding tundra in a few more seasons. Hhere the tundra was removed to dig the reserve pit, a pond: now exists (Photo 6). This occurs even though the pit was filled level because without the insulat- ing tundra, the permafrost melts near the surface causing the ground to slump leaving a depression to catch water. The adjacent ice-airstrip has had an even better recovery than the drill site as can be expected due to a lower level of useage. Photo 7 shows the runway-unused turdra interface. approved the condition of this abandoned location.- Union-Kookpuk State No. 1 (Sec. 19, TliN, R7E,. U.M.) - Enroute to the Union- Kookpuk No. 1 we flew along the-old, now infamous,-road built years ago by. plowing the tundra into a bern and driving on the berm. It looked l ike-a semi-dry stream. Several lakes near it had drained and were dry. The Kookpuk No. 1 was P&A 3/10/67. From the air it was'difficult to spot the well pad (Photo 8). We landed near the well marker (Photo 9) which was a 2" pipe cemented inside the 9 5/8" casing. The well information was bead welded on a l' x 2' steel plate welded to the 2". pipe. About 1BO pilings were cut off about 3' below ground level. Then the well pad was leveled., hand picked clean, fertilized and reseeded with a mixture of native and domestic grasses. The final hand picking was in a pile at the edge of the pad (Photo lO). Helmricks will. haul this debris to his place by snow machine as soon as it snows. The entire area was smooth and clean (Photo Il) with the exception of the pile of debris and a small pond formed by soil slump at the reserve pit location {Photo 12). Reseeding and natural vege- tation has been effective on the pad and even better on the adjacent ice airstrip (Photo 13). I approved the condition of this abandoned location contingent upon removal of stockpiled debris to Helmricks' place in t974 as soon as travel by snow vehicle on the tundra is permitted. I gave Jim Callender and Bob Anderson, copies of "Field Inspection Reports" indicating satisfactory inspections of the Kookpuk and Kalubik Creek wells and the contingency on the Kookpuk well. Copies of the reports are attar, bed. Hot~'~r L. Butte11 -3- August 29, 1974 The weather had been chilly, windy and overcast all day and was now sprink- ling as we returned to Bud's in the chopper. Bud gave us a tour of his island. We saw his "climb down into deep freeze" 30' down into the permafrost, a prolific greenhouse which provided fresh vegetables for our dinner, the current land fill and reclaiming operation, hangar, vehicle maintenance shop and garage, and moving equipment. Bill Copeland had requested a ]ook at Thetis Island, which is in the Beaufort Sea, about 8 miles northeast of Bud's island. Union is still investigating using the island to drill an exploratory test offshore. We all boarded the chopper and flew to Thetis Island. Bud has a little cabin there built out of 6" x 10" timbers {Photo 14). A guide and his wife who work for Bud are liv- ing in the cabin and improving it. Bud rents the cabin complete with food, water and fuel to people looking for a lot of privacy and solitude. The island is all good gravel. Jim Callender and Bud discussed installation of strain gauges at strategic points around the island to measure and record stresses imposed by the winter ice. We returned to Bud's house, visited over hot tea, .then departed the BP Opera- tions. Center at 5:20 p.m. Carl Lesher and Yank Sumpter met our chopper on arrival. Carl, Yank, Bill and I left immediately for. the CSO-Gwydyr Bay State "A" No. 1 well site, while Jim and Bob went inside the BP Operations Center for their pre-scheduled tour. GSO-Gwvdvr ~,av Stai~e "A" Not 1 CS~c. 31. T13N. RI~F. U.M.) - We landed on the gravel Well pad in the mouth of the Kuparuk River at 6:00 p.m. On May 4, 1974, I made a pre-final inspection of this location with Carl and Yank. At that time, leveling and filling with heavy equipment was being completed so the equipment could be moved across the ice road before break-up. On July lO, 1974, Dr. Eb Rice, University of Alaska engineering professor, called me and asked that CSO not be required to remove the hydrology study station erected in a vertical joint of 13 3/8" casing off the southeast corner of the pad {Photo 15). Dr. Rice said the university wants to record river water levels for as long as they can keep the station and that they would assume respon- sibility for its removal when it was no longer useful. Permission was granted. I noted that the University of Alaska had erected a ladder at the hydrology station since my last visit. The gravel pad was level and very clean {Photo 16). Some shallow puddles of clear water were standing on the western side of the pad {Photo 17). The abandoned well marker was a 4" pipe secured inside the well casing. The marker extended 5' above ground level and had the proper well information bead welded on it (Photo 18). I gave Carl a copy of "Field Inspection Report" indicat- ing the condition of the abandoned location was satisfactory. A copy of the report was forwarded to Robert Brady, CSO Regional Production Manager in Denver, and a copy is attached. We returned to the BP Operations Center where Carl and Yank deplaned. Bob and Jim boarded and we flew to Deadhorse arriving at 6:55 p.m. We departed by commercial aircraft, an hour.late, at 8:00 p.m. and arrived in Anchorage at 10:30 p.m. Homer L. Burrell -4- August 29, 1974 In summary, I made satisfactory abandoned location inspections of one Cities Service well and two Union wells on the North Slope. ~'Field Inspection Reports" are attached. I also checked a potential Union offshore exploratory well loca- tion.

Five feet and eleven feet below ground level two salt water flows were encountered. The flow~was of sufficient quanity to wash out the cutting from the bucket. Operations were suspended for the day. Overnight the 36" conductor hole filled up with salt water. A cellar jet was used to pump the water from the conductor hole. The hole was drilled to eighteen feet below ground level and the water was continuously jetted from the conductor hole overnight. The 36" conductor hole was drilled to 30 feet. The hole was opened to 56" to 20 feet below ground level and then opened to 60" to'20 feet below ground level. 54" corrugated culvert was set at 20' and the annulus packed with dry cement and dry gel, sealing off the water flow. 36" Conductor hole was drilled to 76' below ground level-and 30", 1/2 wall, 157.53#/ft. conductor was cemented in place with 300 sacks of Articset cement @ 16.0#fgal.

J.a. nuary 11., 1974 - I departed Anchorage by coammrcial aircraft at 7:0~ a.m. for' Deadhorse.

"A" Ne. 1 drilling well-on Gonder Island in the Beaufort Sea at the edge of ~ Kuparuk River delta. I arrived at Oeadhorse at 11:55 a.m. The Oeadhorse temperature was -26°F with a 15 knot west wind. Yank Sumpter., with Driiltng Services Inc. over- seeing drilling operations for Cities Service, was on the plane with me. Carl Lesher, CSO drilling engineer out of Denver,_ Colorado, was also on the plane although I didn't meet .Carl until I landed at Deadhorse. Carl alternates with Jim Gonders, CSO special projects engineer, currently at the well. Harm OeBoer, CSO expediter employed b~ Orilltng Services inc., - met the plane. I saw Red Morast, Mukluk fereamn, in the Oeadhorse ter- ~ ~u~ ~,L~ mlnal. I asked him for a State contract vehicle $o I-could tour the ,(~v6~ To area but he said all the Mukluk trucks were leased out and none were due to be returned very'.soon. Harm, Carl, Yank and I drove.to the Nabors Drilling Company camp to pick up a second vehicle. Enroute Harm advised us tha~ the casing power tongs broke at lO:O0 a.m. today after., rurming six Jot~ of 13 3/8" casing. Another set of casing tongs was borrowed from BP,_ thawed oat, and by the time we arrived two additional Joints had been run.. This set the BOP test schedele back several hours. Carl and Yank .continued on to the CSO drilling well while I stayed with Ham so we could tour the Prudhoe Bay area to moni mr the 1 iai ted acttvity. The vehicle we were to pick up was having a head :bolt heater repla~ so. we had lunch at the Nabors camp whtle the repatrwas being made.

Their 13 3/8" casing had stuck fast with 630 feet in ~ bole. By 6:45 p.m. the pipe had been freed and stuck again wtth 642 feet in the hole. This time there was four feet of verttcalmovement. ~orki'ng the pipe-failed to free it.

Shortly before ~rl~~. after trying everything else, they pulled hard on the cast~-~a-couple of times and t t came free. They proceeded to pull all of the': out of the hole and lay it dem.

Jim wtllleave for Tulsa as soon as the 13 3/8" castng is cemented and JOJm Ross just arrtved from Anchorage. Don Spafford, ~tth Recall, arrived here Thurs~ to install the 20" castnghead after 13 3/8" casing is .cemented. The Nabor's tool pusher is Bill Marmon. The last 90 foot stand of casing ~as pulled out .of the hole about g:O0 a.m. The gutlty centralizer was on the. botto~ Just above the castng shoe. The hinge was broken and the centralizer ~nt. They surmtz~ that some hard ftll accumulated in b~e hole ahead of tb~e castng and the centralizer hung on it and broke.

Butte11 -3- January 23, 1974 compounded by all new drtlllng crews whtch are mot famtliarywtth thts rig or with working as a team. As the result of th.is and a series of normal rig start-up problems, it wes ll:40 a.m. before the first joint of 13 3/8" casing was started in the hale. The casing was run without any centralizers in the hope that it would minimize bunching hard mate_rial in the hole that might stick the casing. All 2,700 ~t of casing was in the hole at 8:00 p.m. a~d mud was cirCUlated for Z 1/2 hours. Cement and materials were made ready and they started pumping cement slowly at 11:15 p.m. The cement plug was down at 1':45 a.m. The weather changed today, it warmed up to -6° F, the ~.nd switched froa west to south and increased steadily. By evening we had a real "arctic blow". January 14, 1974 - This morrjlil~ ~dhorse reP~orted-northwest winds of '~5'"knots ~sti'ng to 50 knots, ~rature-ll~ F and zero visibility. Tod~ was Arew change day but, due to the weather, the casing crew and several others, totaling 17, will be delayed until flights can be resumed. r~ BP was ready this morning to run their 13 3/8" casing in their No. A-7 well. They radioed this rig for return of their power casing tongs. When the wtnd dies down they will be returned. Progress toward testing the BOPE .pressed slowly forward today. A full open (FO) cementing tool was run in the 13 3/8" casing string 25 feet below the 20" casing shoe. After cementing, the above cementing tool was opened and fresh mud was circulated in the 13 3/8"-20" annulus to surface. This mud will be replaced with .on-~ztng fluid before run- ntng g 5/8" casing. The 13 3/8" casing was cut off at 8:30 p.m., the 2,000 pstg hydrtl was remo~, ~ the 20" to 13 3/8" trlange l~talled and pressure tested to 1,500 pstg. The road to this rig was drifted shut and the. ~mter truck was not able to move for 1 1/2 days. The camp water usage i.s 500 B/D and the rig water usage averages 1,000 B/D, At these.rates the mmeplent shed -supply gets low fast, This morning all unnecessary water usage was forbidden, At midnight about 1/2 of the outgoing personnel started out for Deadhorse in a truck behind a cat, a grader, and a water truck, in that order. At 6:30 ~.m. they radioed that they had reached the )labors camp, seven miles from here. Janum.~_].5,_]974 - The crew st?ted setting the drill spool ar~ bla~Jt preventers at 7:00 a.m. At lO:O0 a.m. the ~tnimj .out-going personnel left Demdhorse to catch the 12:30 p.m. flight. At 12.30 p.m. the ram BOP's and Itydrtl were bolted in place. Ntppling up and compacting all of the various valves, fill line, kill line, cb~ manifold, pitline and emariency fill lines continued for the remainder .of bhe day and through the night. Carl Lasher, Dick Semeniuk, Nabors drilling engineer, and I discussed details of the BOPE 'pressure test. Their BOP's ~ere fresh out of the shop where they had been completely overhauled. Hamer Lo Butte11 1974 The ~eather tocl~ was cle&r and .-20° F with a moderate breeze. January 16, 1974 - The weather continued mostly Clear, calm and -20o F. ~i~pl'lng" up was complete early but their test plug t~s too large te go through the BOP's. There was a tam hour delay until the proper slzed test plug was borrowed from BP. Carl Lesher, Yank Sumpter, Btll Ka~ and ! sta~ ser!ous pressure testtng at Btdmorntng after the necessary equipment wes assembled. On the ftrst serles of trials the hydrt1 was clo~ and leaked, the p~pe rams ~ere closed and t~o valves tn the choke manlfold and a unton leaked, then they suspected that the test plug leaked, and all at pressures of 200 psJg or less. As these leaks were repetred and test pressures were 1ncreased, more unlons and more valves on the choke-' manffold, kt11 11nes and ftll l*ines looked. panuer~ 17, 1974- At 3:00 a.m. *it vas -28° F, calm, clear, and all of '~b Valves had been repaired or replaced. Th~ .test plug was screwed onto a dr111 ptpe Jotnt and Installed tn the castnghead. The hydrJ1 was closed and the outstde valves on the Choke manlfold, ktll 11ne, f-ill 11ne, and emergency ftll line were closed. The 3" valve to the 20" casing was left open and all ptp*ing, valves, .choke manifold and hydrt1 were pressured to 2,500 pstg. At thts pressb~e there was a sltght pressure bleed matched by a dribble from the open valve to the 20" castng *ind*icattng a sl*ight 1oak by the test plu§. The hydrt1 was op-~d, the p*ipe rams closed and the assen~ly pressured to 3000 ps*ig. The results were the same. The ptpe rams ~ere ~ and the test plug ~as removed. The blJnd rams were closed and the assembly and 13 3/8" casing were pressured to 400 pstg. At th*Is pressure mud was flo~tng freely from the 3" valve to ~e 20" casJ~ Jnd!cattflg (1) the FO cemnttng tool was not shut, or (2) the 13 3/8 cast~, had beefl collapsed due to freeze back or (3)expansion of'-mud t~ 1500. feet of 13 3/8"-20" and 13 3/8'-open hole arum11 due to pressure Jnslde the 13 3/8" castng.

Thts t*ime the test plug held t*ight and there was no leakage or pressure loss. ! 1nspected the BOP remote closJng controls and had them close the BOP's w-i th them. The test plug was recovered aad the kelly was connec~ to the swlvel. Ustng a spectal, test n*ipple and a small pump the keTtyco~, Jnstde BOP, kelly valve, and eeergenr~ floor valve ~ere each operated _andfte_sted _to 3,000 9stg wt.~hout a_Ry p~e. s.sure losses.

GonderS 9/18/'73 CITIES SERVICE OIL COMPANY DRILLING PROCEDURES 1. Low pump rates will be taken every 500' of hole or when jet sizes in the bit are changed or when the mud weight is changed. The low pump rate will be recorded on the drilling report at the time it is taken. Two rates will be taken each time. This pressure loss will be used in conjunction with SIDPP to circu- late out a kick. 2. Mud weight will be increased only when the bit is off bottom and not drilling. 3. Bottoms up will be circulated before tripping out of the hole. 4. All trips will measure the 1st 5 stands and 2nd 5 stands for fill-up. The hole will be filled on every 10 stands of drill pipe and on every stand of heavyweight or drill collars. With any deviation from the calculated fill rate the trip will be stopped and the bit returned to bottom. J. G, Gonders September 19, 1973 CITIES SERVICE OIL COMPANY DRILLING BREAK PROCEDURE 1. A drilling break is a drilling rate 2 times faster than that of the last 25 or more feet. 2. Drill only 4 feet of a Drilling Break Pick Up Off Bottom high enough for Kelly to clear BOPE. If drag is encountered during pick up, work drillstring only a minute or so, even if it does not free up. 3. Shut Pump Down and Check the Hole For Flow. Check the Mud Volume Charts and Guages, the Mud Weight Guages, In and Out and the Pit Markers in each mud tank and write down the changes shown, if any. Weigh the mud in the Shale Shaker Box and record the weight. Weigh the mud at the pump suction and record the weight. 4. If the Hole Flows., shut the Hole in following the Well Kill Pro- cedure. Notify Cities Service Representative and Toolpusher. 5. If the Hole Does Not Flow, circulate bottoms up. (The time required to circulate bottoms up can be learned from the mud loggers at any depth). Continue to watch the mud volume and weight. a. If the mud circulated from bottom is cut with water or gas no more than 10 feet additional hole is to be drilled before circulating bottoms up again. Notify Cities Service Representative and Toolpusher. (1) A maximum of 30 feet of hole in a drilling break is to be drilled before circulating bottoms up. (2) No Connection is to be made in or after a drilli.ng break before circulati.ng bottoms up. (3) Circulate Bottoms Up after maki.ng the connection before dri 11 i ng ahead. 5. Continued b. If the mud circulated from bottom is not cut: (1) Drill Ahead, using same procedures used before the dri 11 i ng break. (2) Continue to watch closely the mud volume and weight indicators. J. G.
