However, Scott Sappington expressed concern about the drainage that was coming out from under ~he downhill side of West Kurupa as he felt it contained fuel oil. He also expressed concern over the same type of drainage at East Kurupa, but he said that it did not appear to have fuel oil in it. He did take samples of the water to have it analyzed.

Consequently, we are presenting the following list of your abandoned and/or suspended ~,~ells. Many of these are now more than one year old and are not in compliance with regulations. Others should have the final inspection completed this summer while weather permits. This list covers the years 1975 to date. There may be some earlier %~ells that also need inspec- tion. If you have any earlier wells to be inspected this summer please inform us. Therefore, %~e are requesting a _cned. ule from you for this summer when our field inspectors can accompany your representa- tives to these sites for the final clean up inspection. ~rs tru~; ;/""?

Attachment B Development Plan Wes~ Kurupa Unit Well No. 1 I. DESCRIPTION OF AREA AND NATURAL SETTING The proposed location is approximately 86 miles west-southwest of Umiat and 140 miles south of the Beaufort Sea in the foothills of the North Slope of the Brooks Range. There are no roads, towns, camps or airstrips in the immediate vicinity of the location. The site lies near. the Kurupa P~ver and is at an elevation of 1351' above sea level. Hilly terrain is prevalent, increasing in ele- vation towards the Brooks Range to the south. Vegetation is limited to tundra grasses with scattered iow shrubbery along streams. There are no large trees in the area. The only active stream channel in the vicinity is the Kurupa River, which flows in a northerl~ direction, roughly 1-1/2 miles southeast of the location. No wildlife has been observed in the vicinity on previous visits. II. CONSTRUCTION -AND OPERATING PLANS A. Access and Operating Plans Upon receiving an approved drilling permit, Amoco plans to move in surveyors and stake the well location, pads for drill- ing rig, campsite, and staging area, as well as airstrip, road and gravel source area. Following freeze-up, earthmov~n~ '11 -2- of gravel required for this location. Gravel will be obtained from unvegetated gravel bars along the river channel extending in a southwesterly direction' from approximately Section 34, T65, R14W, UPM. The river is a meandering stream that has narrow elongated gravel bars near the stream bed that are unvegetated and above the normal water level. The gravel will be mined from these bars down to the stream water level. The haul road which will be utilized to transport this gravel will follow the stream bed. The area of the river channel that will be required for obtaining the requested 70,000 cubic yards of gravel is not known at this- time due to unknown depth and area of the indicated gravel bars. · Crews will be maintained at the location in a camp to be fur- nished by. the drilling contractor. Drilling operations will proceed on a 24-hour per day basis. A contract caterer will provide food, linen and janitor service at the camp. Location and Details of Planned Construction and Other Surface Alterations Areas of planned construction have been sketched on the map ~ncluded as Attachment B-1'. More detailed views of the drill- ing and camp areas are S~hown on Attachments B-2 and B-3. In an effort to minimize the impact of this proposed explora- tory well on the environment, we plan to conduct all operations during the winter months. Initial move-in of men and equipment will commence after freeze-up of the tundra surface and opera- tions will be discontinued prior to the spring thaw. In the event that total well depth is not reached in this time inter- val, equipment will be stored at the location 'throughout the summer and operations will be resumed the following winter. Every effort will be taken to minimize the disturbance within the area. We propose to utilize nearby gravel sources.to con- struct all=weather pads for only the drilling rig, camp and materials storage areas. Gravel quantities will be minimized in the construction of these all-weather pads by utilizing styrofoam type insulation to assist in maintaining a frozen Subgrade. Sufficient gravel fill will be required under the insulation to-provide a flat surface, and at least tw° feet of gravel will be required over the insulation to distribute loading and to insure that the insulation, is not compressed. The insulation will be totally covered and will not be removed when operations are terminated. The use of gravel is not anticipated in the construction of the roads or airstrip at the site. We propose to utilize only ice and snow in the-construction of these facilities to pro- vide surfaces usable in the'winter. This type construction should not leave a lasting scar following teraztnation of our activities. Construction is planned as follows: le · Drilling Pad - approximately 400' x 100' to accommodate drilling rig and associated equipment, reserve pit and burn pit. The drilling contractor and specific drilling rig to be used have not yet been selected. Attachments B-1 through B-3 have been prepared using a rig layout for a Parker Drilling rig currently on the North Slope. Pad configuration and dimensions are subject to change depend- /rig upon the drilling rig selected for the job. The location selected is on the side of a hill and if gravel is encountered in leveling the location, it will be used to.supPlement river bed gravel in the construction of the .all-weather pad. The reserve pit will be located adjacent to the drilling rig and will have a capacity of approximately 30,000 barrels, requiring approximate dimensions of 80' x 310' x 6' deep. The pit will be excavated as required and diked w~th earthen and gravel walls. The pit will be sealed with bentonite to prevent seepage. _ Two additional small pits will be required on the drill- ~ng pad to provide fOr diposal of incinerator ash and for burning waste petroleum products recovered during testing operations. Both the burn pit and the reserve pit will be back-filled with at least five feet of gravel upon completion of-drilling operations to insure that liquid rema/ning in the pits are kept in a frozen state. Camp Area - approximately 80' x 350'. The layout may be revised upon selection of the drilling contractor. A 50-man camp is anticipated, complete with quarters, galley, utilities, water treating and sewage and solid waste disposal facilities. A pit will be constructed adjacent to the camp pad to retain water discharged from the sewage treatment system. This water will be reused, where possible, as drilling make-up Water. 3. Staging Area - approximately 400' x 400'. The layout will provide material and fuel storage, t~bular goods racks, and an aircraft hang~r and taxiway. This area may also be modified upon selection of rig and camp. Ce 4. Airstrip - approximately 5000' x 150' of usable surface, overall width 200'. Strip to be oriented with a bearing S 85° E on the flat area southeast of the wellsite. The strip will be constructed of ice and snow to give a. surface which will accommodate Hercules type aircraft capable of payloads ~up to $0,000 lbs. · $. Access Road - No permanent roads will be constructed in the area. Winter roads will be constructed of ice and snow. A winter access road will be built from the south- east end of the airstrip to the stream and proposed gravel source beginning in Section 34, T6S, R14E. A~ survey plat will be furnished showing actual layout of the rig and completion of further .ground surveying. Cutting or disturbance of the tundra will be avoided except where necessary to level the wellsite or for pit construction. Production, Transportation and Marketing Facilities in the Event.of Discovery of Commerical Quantities of, Hydrocarbons ,. In the event of an oil .discovery, tentative plans are to install treating facilities on the drilling pad. The crude will eventually be delivered to market at some delivery point on the trans-Alaska pipeline, roughly 160 miles to the east.. The type and capacity of the facilities will be dependent upon the quality of the discovery and upon the eventual market for the oil.~ In the event of a gas discovery, th~ type of facility will also be dependent upon the gas market. It is likely that a gas discovery at this location would be shut-in for some time unless of sufficient magnitude to attract an immediate market outlet. Planned and Alternate Water Supply Sources The primary source of water for camp and drilling operations will be the Kurupa River near the proposed gravel source in Section 34, T6S, R14W. If the water table in the area is sufficiently high, water may be taken from the'gravel pit" following.completion of mining operations.. It is felt that sufficient quantities of water will be available from the river. If the river flow stops prior to completion of drill- ing operations, however, water .may be hauled from the COlville River some 10 miles to the north, which is believed to be of sufficient size not to freeze up. III. SURFACE PROTECTION AND RESTORATION PLANS A. Handling and .Disposal of Waste Materials Excess-drilling fluids, previously described as a fresh water- base mixture of relatively bland materials, will be disposed of by back-filling the reserve pit at the conclusion of the drilling operation. Oil or substances which may cause damage to vegetation will be treated or disposed of prior to back- filling pits. Combustible waste will be disposed of by incineration where possible or by open burning in a burn pit. 'Ashes from incineration processes will be placed in the burn pit and buried at the conclusion of the operation. Non- combustible wastes will be buried when pits are back-filled or will be removed from the area. We tentatively plan to dispose of sewage by means of a physical- chemical disposal plant. The exact size and type of such a unit will not be known until a specific contractor and rig are selected. The equipment will likely be equipped with incinera- ~on .capabilities for sewage, dunnage, and other solid wastes. Liquid effluent from the sewage treatment plant will be utilized as make-up water from the drilling mud system. The design of sewage and solid waste disposal systems will be reviewed with the Department of Environmental Conservation of the State of Alaska for its approval. B. Surface Restoration All pits will be back-filled 'and dikes surrounding storage .areas will be leveled. The reserve pit will be mounded over the gravel to allow for a certain amount of settling subse- quent to back-filling. Ail debris and waste materials will be incinerated, buried'or removed from the area. The required surface dry-hole marker will be installed on the wellhead if appropriate and the cellar.back-filled. The pad surface will be reseeded and/Or fertilized according to recommendations to be solicited from the Bureau of Land Management. C. Fuel Storage and Handling Fuel required during dirt work and drillin~ operations in- cludes diesel, regular gasoline, aviation gasoline and Jet fuel. Storage units will consist of barrels and fabric bladder tanks. Ail fuel storage areas will be Surrounded by dikes constructed of gravel of sufficient height to contain the maximum stored volume. The sides and bottom of each storage area will be lined with an oil-resistant plastic material and seams sealed to present an impervious barrier. The plastic material will be removed prior to abandoning the location. D. Oil Flow Containment Although chances of a blowout are considered extremely remote, the following is a brief contingency plan for' oil containment in the event of an uncontrolled oil flow: The drilling pad will be contoured to provide drainage from north to south toward the reserve pit and eventually toward a small valley proceeding easterly through the northern portion of Section 4, T7S, R14W. This valley, which drains a large area to the southwest, is dry follow- ing break-up and run-off. The valley may be dammed at a point in the north half of -Section 4 to create a large containment area. Heavy equipment will be on hand throughout the drilling opera- tion to create such a dike or dam. e The oil that would be trapped behind the earthen dike would be collected, transferred to a burn pit and ignited. 4, Appropriate action will be taken as required to prevent possible pollution of active streams.
