DOC Memorandum To.' Re: State of Alaska Cancelled or Expired Permit Action EXAMPLE' Point McIntyre P2-36AXX API# 029-22801-95 Oil and Gas Conservation Commission This memo will remain at the front of the subject well file. Our adopted conventions for assigning APl numbers, permit numbers and well names did not specifically address expired or cancelled permits. This omission has caused some inconsistencies in the treatment of these kinds of applications for permit to ddil. Operators have asked us to adopt formal procedures for this class of permit application in order to prevent future database disparities. If a permit expires or is cancelled by an operator, the permit number of the subject permit will remain unchanged. The APl number and in some instances the well name reflect the number of preexisting reddlls and or multilaterais in a well. In order to prevent confusing a cancelled or expired permit with an active well or multilateral these case sensitive well identifiers will be changed for expired and cancelled applications for permits to ddll. The AP! number for this cancelled or expired permit is modified so the eleven and twelfth digits is 95. The well name for a cancelled or expired permit is modified with an appended xx. These procedures are an addendum to the APl numbering methods described in AOGCC staff memorandum "Multi-lateral (wellbore segment) Ddiling Permit Procedures, revised December 29, 1995. AOGCC database has been changed to reflect these changes to this permit. St-eve McMains ' ~ '"'- Statistical Technician Environmental Department Alaska District Unocal Oil & Gas Div, J Unoca!

The information submitted complies with the requirements of the Solid Waste Management Regulations (18 AAC 60) and contains essentially the same information as previously submitted and approved for the Ruby No. 1 Solid Waste Oisposal Permit. Unocal plans to drill an exploratory well on Block 113, Prudhoe Bay Uplands, state Lease sale 69A (ADL 37311~), Section 2,.___TB.N,_~_R~_Meridian. An ice road will be constructed betwe~~ng"~:~~ ~nd the Ruby No. 2 location. Existing roads and structures within 2 miles of the proposed site will be utilized for all construction and equipment mobilization. The decision to construct the ice road and pad for Ruby No. 2 will be made at the end of the drilling operation of Ruby No. 1. At this time, Unocal anticipates spudding Ruby No. 1 approximately February 28th. The below-grade reserve pit will be located on the ice pad to contain the cuttings from the well. It is estimated that 6,200 cubic feet (1100 barrels) of drilling waste will be generated and disposed in the pit. No other drilling or domestic waste will De disposed in the pit. Drilling fluids will be disposed by annular injection in accordance with the General Wastewater Disposal Permit 8740-DB002 for the North Slope.

The specific items required by 18 AAC 60.210(b)(4) are addres- sed below. Part ~ Plate 4-1 shows the designated portion of the facility, including the active portion and the location of the proposed reserve pit. Since this is a new facility to be used for short-term explo- ration, there is no closed portion, and only one disposal cell in the reserve pit is planned. There are no containment structures or trenches at the facility. Part B The designated area for storage of cover material, as shown on Plate 4-1, is on the ice pad adjacent to the reserve pit. Part C Plate 4-1 shows the anticipated pattern and direction of surface- wager flow at the facility. Because of the presence of per- mafrost, there is no ground-water flow. Drainage and surface- water flow are discussed in greater detail in Attachment 6. Part.D The pad and the reserve pit location on the pad have been aligned to minimize impacts on drainage patterns. Because of the elevated flat surface, no diversion trench or other special drainage device is needed. The fluid management plan presented in Attachment 9 identifies methods to be used to minimize the accumulation of liq- uids in the reserve pit. 0056R - 4-1 February 14, 1989 ORGANIC SOIL STOCKPILe7 r-A ~- MINERAL SOIL STOCKPILE B ' 1 ~ - !

Ail developmental and drilling activities at Ruby Nos. 1 and 2 will be carried out during the period December 1988 through April 1989. Ice road and pad construction for Ruby No. 1 began in late December 1988 and were completed by mid-January 1989. Rig-up at Ruby No. 1, which is dependent upon contractor availability, will probably begin around February 18, 1989. We anticipate spudding Ruby No. 1 on or about February 20. The decision to construct the ice road and pad for Ruby No. 2 will be made at the end of February after Ruby No. 1 well is drilled. If Ruby No. 2 is drilled, it will require about the same amount of time to complete. Rig-up would begin during the week of March 4, 1989 at the earliest. Rig-down and demobilization of rig, camp, and support equipment will be completed by mid-April 1989. The proposed dimensions of the reserve pit at the Ruby No. 2 drill site are shown on Plates 4-1 and 4-2. As shown on Plate 4-2, the reserve pit will be excavated to a depth of 10 feet and will have plan dimensions of 30 by 150 feet. The total capacity of this reserve pit, assuming 2 feet of freeboard, is 36,000 cubic feet. Drilling waste generated during drilling will include drill cuttings, drill mud, cement, and wash-down water. We estimate that approximately 6,200 cubic feet of solids and up to 12,000 cubic feet of waste fluid will be generated during drilling. The reserve pit will be excavated by ripping with a heavy tractor. The excavated organic soil cover and underlying mineral soils will be segregated and stored in separate stockpiles on the ice pad adjacent to the reserve pit as shown on Plates 4-1 and 4-2. These materials will be used to bury the drilling solids in place as discussed below and in Attachment 11. The volume of drilling fluid produced during drilling operations that enters the reserve pit will be minimized by utilizing equipment for separation of liquids and solids (i.e. shale shakers, centrifuges, etc.). If a signifi- 0056R - 5-1 February 14, 1989 cant amount of fluid accumulates in the reserve pit during drilling, it will be removed immediately and stored on site pending annular injection in accor- dance with the Fluid Management Plan (Attachment 9). This plan will prevent over topping while drilling is underway, and will prevent fluids from reaching the active layer. Solids will be discharged directly to the reserve pit where they most likely will freeze soon after placement. If solids tend to mound, they will be leveled with a small bulldozer or other appropriate type of earth-moving equipment. Significant accumulations of snow will be removed either by snow blower or other applicable methods. Snow that is contaminated with mud will be stored on-site until it can be injected down the backside of the well. Upon complecion of all drilling and testing, the reserve pit will be closed out in accordance with the procedures set forth in Attachment 11. For safety reasons, the reserve pit has been designed to provide for disposal of a quantity of drilling solids substantially in excess of 6,200 cubic feet, and sized to ensure a cap of at least 8 feet above the waste. Closure will include removing all pumpable fluids from the reserve pit, leveling the frozen solids, and backfilling the excavation with the soils stockpiled adjacent to the reserve pit. The top of the drilling wastes will be well below the depth of annual thaw. 0056R - 5-2 February 15, 1989 ATTACHMENT 6 DESCRIPTION OF PHYSICAL ENVIRONMENT (Specific Information to Describe Items Requested in 18 AAC 60.210(b)(6)) As shown on Plate 3-1, the Ruby No. 2 well site is located in the SW1/4 of Section 2, T8N, RSE, Umiat Meridian. This well site is approximately 25 miles south of the Beaufort Sea coast and 25 miles east of the Colville River. The proposed Ruby No. 2 well site location lies at an elevation of about 250 feet Mean Sea Level (MSL) datum. The surrounding terrain slopes gently down- ward to the Miluveach River in the west at a grade of about 2 percent. There are no lakes within 2 miles of the well site; however, a small westward-flow- ing tributary of the Miluveach River lies immediately south, and a marshy area bordering the Miluveach River lies approximately 1/4 mile west of the site. A map of the drainage in the vicinity of the well site is presented on Plate 4-1. As all site activities will take place during the winter, impacts to surface-water flows are not anticipated. No site-specific soil information is available in the vicinity of the well site. Regional studies* performed in adjacent areas by the U.S. Geolog- ical Survey and others indicate this area is generally underlain by alluvial sand and gravel deposited by streams flowing from the Brooks Range to the south. As a result, we anticipate the organic-rich surficial soil (tundra) is underlain at a depth of approximately 1 foot by sand and gravel containing variable amounts of silt. Bedrock probably lies within 20 feet of the ground surface at this site. Geology of the Shaviovik and Sagavanirktok Rivers Region, Alaska, 1961' U.S. Geological Survey Professional Paper 303D. Geology of the Chandler River Region, Alaska, 1963' U.S. Geological Sur- vey Professional Paper 303E. Alaska Regional Profiles - Arctic Region, 1975' State of Alaska. 0056R - 6-1 February 14, 1989 One of the dominant features of this area is the continuous layer of perennially-frozen ground known as permafrost. Permafrost at the site will extend from a depth of about 2 feet to approximately 1,500 feet. The active layer (that zone which undergoes annual thaw and refreezing) will be approxi- mately 2 feet thick in undisturbed areas. Ice wedges and lenses may be pres- ent within 20 feet of the surface. The presence of continuous permafrost pre- cludes subsurface drainage and the existence of freshwater aquifers. The climate in this area is typical of the North Slope--severely cold temperatures and blowing snow in the winter and mild temperatures during the brief summer. June, July, and August are generally the only months having mean temperatures above freezing, while the months December through March all have mean temperatures below 0°F. Preliminary findings indicate that there is no historical or archaeolog- ical significance in the proposed area. A letter has been sent to Mr. Greg Dixon of the Alaska Department of Natural Resources requesting agency approval for the project. Information pertaining to this project has been submitted to the Alaska Department of Fish and Game for their review. 0056R - 6-2 February 14, 1989 ATTACHMENT 7 GEOTECHNICAL INFORMATION (Specific Information to Describe Items Requested in 18 AAC 60.210(b)(7)) Site-specific geotechnical information is not available. However, sev- eral studies have been performed in regions adjacent to the Ruby Prospect. These studies were referenced in Attachment 6. The geotechnical information presented below has been obtained from these studies and from our experience. SOIL CONDITIONS The soils at the site may be characterized by two strata. The first is the surface soils, which will consist of tundra (Pt) and organic silt (OL). This layer is typically less than 1 foot thick, has a high moisture content, and has excellent insulating characteristics. Beneath this strata, we expect to encounter silty sand (SM). The sand will be fine-grained, saturated, and contain varying amounts of silts. With increasing depths, the sand will prob- ably become gravelly. Bedrock probably lies within 20 feet of the surface at this site. The soil and bedrock pore water will not contain significant salt. Consequently, its freezing point will be at or near 32°F. THERMAL REGIME The mean annual air temperature of the site is approximately 10 to 12°F. Consequently, except for a small surface layer, probably 2 feet thick, all soils will be perennially frozen (permafrost) to depths exceeding 1,500 feet. THERMAL CONDUCTIVITY The reserve pit will be surrounded by permafrost. Williams and Burr (1979)* have researched the hydraulic conductivity of frozen soils. In * Williams, P.J., and Burr, T.P., 1974, Measurement of Hydraulic Conductiv- ity of Frozen Soils' Canadian Geotechnical Journal, Vol. II, No. 647. 0056R - 7-1 February 14, 1989 summary, they concluded that the hydraulic conductivity of saturated, frozen soil is very low. For practical purposes, the frozen soil can be considered impermeable. 0056R - 7-2 February 14, 1989 Ai~ohorag~ ATTACHMENT 8 LEACHATE GENERATION EVALUATION (Specific Information to Describe Items Requested in 18 AAC 60.210(b)(8)) This site and the proposed disposal activity have no potential for leachate generation for the following reasons' The Dry Option (V) (Table C) is the designated disposal option. Only drilling solids and minor amounts of drilling liquids will be disposed in the reserve pit. No sanitary trash or putrescible wastes will be placed in the facility. Ail development and closure activities will take place during the winter months. The drilling wastes will freeze in the reserve pit soon after placement, well before closure. As set forth in Attachment 11, containment will be achieved through freeze-back (Table D). The frozen drilling wastes will be encapsulated by the impermeable, native permafrost soils. 0056R - 8-1 February 14, 1989 ATTACHMENT 9 SELECTED OPTION FOR CONTAINMENT AND MONITORING AND FLUID MANAGEMENT PLAN (Specific Information to Describe Items Requested in 18 AAC 60.210(b)(9)) CONTAINMENT AND MONITORING OPTION Unocal certifies the containment and monitoring requirements of 18 AAC 60.530(a) will be met by freeze-back of the drilling wastes utilizing Dry Option V (Table C). Per Table D, monitoring requirements for containment by freeze-back include: a) site inspection; b) surface water or active thaw zone monitoring; and, c) installation and monitoring of thermistors. The proposed monitoring program that addresses these requirements is described in detail in Attachment 10. Unocal certifies that the drilling wastes will not contain hydrocarbons as free liquids. Although some of the cuttings from hydrocarbon-bearing for- mations may contain residual hydrocarbons adhering to or contained within the particles, no free hydrocarbons will be placed within the reserve pit. The following section describes the specific features of the fluid management plan. FLUID MANAGEMENT PLAN A fluid management plan has been prepared in accordance with the requirements set forth in 18 AAC 60.210(b)(9)(B). This plan will prevent overtopping during the period the pit is open, and will minimize contact of fluids in the reserve pit with the active layer. The specific features of the fluid management plan are presented below. Solids Control While Drilling The mud system on the drilling unit will be equipped with solids control equipment that will expel drilled solids having a relatively low fluid content to the reserve pit. This equipment will include high volume shale shakers, de-sander, de-silter, and a centrifuge. The primary function of this equip- ment is to remove drilled solids from the mud in ever-decreasing size frac- 0056R - 9-1 February 14, 1989 tions as the drilling fluid passes through the system. The net result of this operation is a scavenging of usable drilling fluid and discharge of low fluid content drilled solids. Fluid Discharges While Drillin~ Various downhole operations may result in discharge of limited quanti- ties of drilling fluids to the reserve pit. Operations requiring mud dilution may also result in some fluid discharges to the reserve pit. Precautions will be taken to minimize the impact of these activities. The bottom of the active zone within the reserve pit will be marked so as to be clearly visible to the operator. Fluid levels will not be allowed to accumulate to within 1 foot of that level to prevent overtopping of the reserve pit and minimize contact between the reserve pit fluids and the active zone soils. Fluid Removal and Disposal Fluids will be removed immediately from the reserve pit using pumping and transfer equipment currently available on the North Slope. Fluids will be stored on-site pending disposal by annular injection down the backside of the well. Accidental Fluid Releases Precautions will be taken to prevent accidental fluid releases on the drilling pad. Minor fluid releases, should they occur, will be contained properly and cleaned up. If necessary, fluid releases could be pumped or drained into the reserve pit until the problem could be corrected. Any emer- gency discharge of this type would be pumped out of the reserve pit as soon as possible. 0056R - 9-2 February 14, 1989 A,c;{ora~e Surface- and Ground-water Inflows Ail work will be performed at this location during the winter months when surface water and the active zone are frozen. Free ground water does not exist within the permafrost at the site. As a result, surface- or ground- water inflow to the reserve pit will not occur. Snow Accumulation Some snow accumulation in the reserve pit is unavoidable. Significant accumulations of snow will be removed either by snow blower or by front-end loader and stored on-site. Snow that is contaminated with mud or drilling fluids will be stored on-site until it can be injected down the backside of the well. Small amounts of contaminated snow remaining in the reserve pit will be spread evenly over the bottom of the pit before closure. CERTIFICATION As required by 18 AAC 60.520(c), this fluid management plan is certified by an engineer registered in Alaska. Bernard Nidowicz, P.E. Civil Engineer - 5640 Harding Lawson Associates 601 East 57th Place Anchorage, Alaska 99518 (907) 563-8102 0056R- 9-3 February 14. 1989 ATTACHMENT 10 MONITORING PLAN (Specific Information to Describe Items Requested in 18 AAC 60.210(b)(10)) In accordance with the requirements of 18 AAC 60.210(b)(10) and 18 AAC 60.310, a monitoring plan has been developed for the proposed reserve pit at Ruby No. 2. The monitoring plan contains a visual monitoring program, a ther- mal monitoring program, and a surface-water quality monitoring program. It also identifies the remedial action procedures to be undertaken should prob- lems arise. Active thaw-zone monitoring is not proposed because it is believed that sufficient surface-water sampling points exist within 50 feet of the limits of the reserve pit. The Quality Assurance/Quality Control (QA/QC) for this monitoring plan is presented in Attachment 13. This monitoring program has been designed to monitor the reserve pit during drilling, to establish baseline data for indicator parameters, and to monitor the pi~ for five years after closure. In designing the monitoring program, we considered the location of surface water and continuous per- mafrost. To assist ADEC in its review of this permit application, the appli- cable subsection(s) of 18 AAC 60.310 are referenced in the sections below. VISUAL MONITORING PROGRAM In accordance with the provisions of 18 AAC 60.310(a) and (b), a visual monitoring program has been designed. Specific features of the visual moni- toring program are presented below. The visual inspections shall be conducted by the Drill Site Super- visor or his designee. The person conducting the visual inspection will be familiar with the permit requirements, the requirements of 18 AAC 60.310, and the requirements of the visual monitoring program. 0056R - 10-I February 14, 1989 The visual inspection will be conducted daily during drilling operations and during the first, third, and fifth summers (during the period August to September) following the reserve pit closure, or at a frequency appropriate to the reserve pit operations as specified in the permit. The inspection will be conducted to detect: 1) signs of damage or potential damage from settlement, ponding, leakage, thermal insta- bility, frost, action, erosion, thawing, or operations at the facility; 2) escape of waste or leachate or any improper waste disposal; and, 3) damage to the structural integrity of the con- tainment. A record of the inspections will be kept at Unocal's Anchorage office. Variations requiring remedial action will be reported to ADEC in a timely manner. A report will be submitted to the designated ADEC representative. This submittal will include all observations of a potential environmentally degrading nature and any action taken or planned to ameliorate the situation(s) to ensure that the reserve pits are in full compliance with 18 AAC 60. THERMAL MONITORING PROGRAM The proposed reserve pit will be located in continuous permafrost. In accordance with 18 AAC 60.310(g)(2), a thermal monitoring program has been designed. Thermistor string construction, installation, and monitoring proce- dures are presented in this program. The locations for the three thermistor strings proposed for this program are presented on the Site Plan, Plate 4-1. Ground temperature monitoring strings will be fabricated using Yellow Springs Instruments (YSI) Model 44034 or equivalent ther- mistor beads. The beads are factory-calculated and have an inter- changeability of 0.1°C and a resistance of 16,330 ohms at 0°C. Thermistor strings will be placed in small-diameter casings installed in the following manner. A boring will be drilled to the desired depth using hollow-stem, continuous-flight augers. 0056R - 10-2 February 14, 1989 The center rods will be withdrawn from the auger string, and the casing lowered inside. The well will be constructed from approxi- mately 1-inch diameter casing composed of polyvinylchloride (PVC) or ductile iron. Samples of the drilling solids will be obtained from the borings drilled for placement of thermistor strings in the former reserve pit. These samples will be tested to determine the crystalliza- tion temperature of the drilling solids. The well will be capped to prevent debris from falling inside. The cap will display the sample station number and the Alaska State Plane Coordinates for the sample station. Drill spoil will be used to backfill the annulus between the casing and the hole wall. The thermistor string will then be placed in the well. The thermistor string readings will be conducted by the Drill Site Supervisor or his designee. The person conducting the readings will be familiar with the per- mit requirements, the requirements of 18 AAC 60.310, and the requirements of the thermal monitoring program. The thermistor string readings will be taken after the reserve pits are closed, and during the first, third, and fifth summers (during the period August to September) following closure, or at a frequency appropriate to the reserve pit operations as specified in the permit. The readings will be taken to verify that the solid waste tempera- tures are at least 0.5°C below the crystallization point of the drilling solids. The readings will be conducted consistent with the provisions of the QA/QC Plan presented in Attachment 13. The results of thermal monitoring during subsequent years will be analyzed, and compared to the baseline data and the results from previous years to identify changes in the solid waste temperature. 0056R - 10-3 February 15, 1989 A record of the monitoring results will be kept at Unocal's Anchorage office. This record will be updated upon receipt of the results of the monitoring program. Variations requiring remedial action will be reported to ADEC in a timely manner. A report will be submitted to the designated ADEC representative. This submittal will include all observations of a potentially environmentally degrading nature and any action taken or planned to ameliorate the situation(s) to ensure that the reserve pits are in full compliance with 18 AAC 60. SURFACE-WATER QUALITY MONITORING PROGRAM Consistent with the provisions of 18 AAC 60.310(g)(3), a program for sampling surface waters within 50 feet of the facility has been designed to detect migration of waste or leachate from the designated portion of the pro- posed reserve pit. Specific features of the surface-water sampling program are presented below. The person(s) conducting the sampling will be familiar with the permit requirements, the requirements of 18 AAC 60.310, and the requirements of the surface-water sampling program. The sampling will be conducted one time during the first, third, and fifth summers (during the period August to September) follow- ing the reserve pit closure, or at a frequency appropriate to the reserve pit operations as specified in the permit. The data gen- erated during the first year will serve as the baseline data. The sampling will be conducted at the locations depicted on Plate 4-1. These sampling locations are approximate and are subject to change based on the surface-water conditions near the reserve pit at the time baseline sampling will be conducted. The final sample locations selected during baseline sampling will be monumented as described below so that the sample stations can be reestablished during subsequent sampling events. 0056R - 10-4 February 14, 1989 Sample station locations will be marked with a steel "rebar" wit- ness stake. An aluminum cap on top of the stake will display the sample station number. Field measurements of conductivity, temperature, alkalinity, and pH will be conducted at each sampling location at the time of sam- pling. The field measurements, surface-water sampling, and data evalua- tion and reporting will be conducted consistent with the provi- sions of the QA/QC Plan presented in Attachment 13. The samples will be submitted to an approved analytical laboratory for analysis. The parameters to be tested and the test methods to be used will be consistent with the provisions of the QA/QC Plan in Attachment 13, the permit requirements, and 18 AAC 60.310(h), Table B. The results of monitoring during subsequent years will be analyzed and compared to baseline data and the monitoring results from pre- vious years to identify any changes in water quality. A record of the monitoring results, including the associated qual- ity control data, will be kept at Unocal's office. This record will be updated upon receipt of the analytical results for the monitoring program. Variations requiring remedial action will be reported to ADEC in a timely manner. A report as described in Attachment 13 will be submitted to the designated ADEC representative. This submittal will include all observations of a potentially environmentally degrading nature and any action taken or planned to ameliorate the situation(s) to ensure that the reserve pits are in full compli- ance with 18 AAC 60. REMEDIAL ACTION PROCEDURES According to 18 AAC 60.210(10)(c) and 60.315(b) and (c), the required monitoring plan should outline the responsibilities and procedures for estab- lishing and taking the appropriate remedial action to repair a damaged facil- 0056R - 10-5 February 14, 1989 ity, clean up any improper waste disposal, and prevent the escape of waste or leachate. Unocal is required to take the appropriate corrective action. How- ever, since no need for remedial action has been documented at this time, a detailed remedial action plan cannot be developed. If and when problems are documented at the facility, Unocal will prepare a detailed remedial action plan specifying appropriate corrective actions for the identified problem(s). If a structural change in or damage to the facility occurs, or if any violation of permit conditions as observed through the visual monitoring pro- gram,~the thermal monitoring, or an inspection by ADEC, Unocal will: Take appropriate corrective action(s) to correct the violation or damage; Prevent the escape of waste or leachate; Clean up any improper waste disposal. If a significant change in water quality is detected within 50 feet of the designated portion of the facility, Unocal will: Determine the extent of contamination; Determine if migration of waste or leachate is the cause of the change in water quality; Evaluate the potential for a violation of the water quality stan- dards; Take corrective actions to prevent a violation of the water qual- ity standards; Notify the ADEC within seven days after detecting a violation of the water quality standards. 0056R - 10-6 February 14, 1989 ATTACHMENT 11 CLOSURE PLAN (Specific Information to Describe Items Requested in 18 AAC 60.210(b)(11)) GENERAL The pit will be closed out prior to demobilizing equipment from the location. The option selected for close-out is containment by freeze-back (18 AAC 60.530), Dry Option V. We consider this option appropriate and in compli- ance with 18 AAC 60 for closing out a reserve pit at this drill site. The waste will be consolidated and graded prior to close out, and a cap consisting of a minimum of 8 feet of native soils will be placed on the waste. Plate 11- 1 shows a plan view of the drill site highlighting the area to be closed. Plate 11-2 shows cross sections of the proposed close-out plan. The plan for closing out the pit is as follows: Consolidate and regrade waste in pit. Cover the regraded waste with a minimum of 8 feet of native soils. The soil will be placed such that the surficial soil will consist of peat and organic silt. Install monitoring instruments and initiate monitoring program as outlined in Attachment 10 (Monitoring Plan). If the waste does not remain frozen* or if a significant adverse change in water quality is detected at the monitoring stations, the following actions will be taken. Determine how much additional cover material is necessary to pro- vide permanent freeze back and apply it. Determine the extent of any vadose zone contamination beyond the perimeters of the facility and if migration from the facility is the cause. * Frozen is defined as a temperature at least 0.5°F below the crystalliza- tion point of the waste. 0056R - 11-1 February 14, 1989 D NOTES: 400' 1) See Plate 11-2 for Generalized Subsurface Profiles CC' and DD' 2) See Plate 4-1 for Drainage Map KEY: O THERMISTOR STRING LOCATION "~ A~ch0rage NOT TO SCALE ~ ' Harding Lawson Associates Engineers, Geolog~s ~ & Geophysicists ...... ~,P~AWN Ruby Prospect Closure Site Plan Lease Sale 69A North Slope, Alaska P L :,T =._ 11-1 0382,199.08 ~ 2/89 2I ACTIVE ZONE _ ;~,-'' ,- .,. -..:: , ._-. :-.:o...o...'. , .....

This attachment details the Quality Assurance (QA) and Quality Control (QC) procedures that will be used to ensure that the technical data generated during monitoring activities are accurate, precise, complete, and representa- tive of actual field conditions. QA is an integrated program designed for assuring reliability of monitoring and measurement data. QC is the routine application of procedures for obtaining prescribed standards of performance in the monitoring and measurement process. MONITORING PROGRAMS AND METHODOLOGIES The following sections discuss the thermal monitoring system and surface-water collection methods that will be used for implementing the moni- toring program at Unocal's reserve pit at Ruby No. 2. Thermal Monitoring Program The purpose of this plan is to detail procedures that will be used to ensure that the thermal data generated during closure and post-closure moni- toring of the reserve pit are representative of actual field conditions. The construction and installation details for the thermistor strings are described in Attachment 10. The thermistor string monitoring procedures are as follows: Completed thermistor strings will be calibrated in an isothermal bath and correction factors will be calculated for each thermistor. The thermistor string readings will be obtained using a switchbox and a Data Precision model 248 multi-meter or equivalent. The multi-meter is capable of measuring and 0056R - 13-1 February 14, 1989 resolving resistance to 1 ohm. When combined, the YSI thermistors and the multi-meter have a precision of ~ 0.1°C and an accuracy of ± 0.2°C. The resistance values obtained in the field will be converted to ground tempera- tures using accepted relationships and the calibration data. If faulty or suspected points are detected when the data is analyzed, the strings will be removed from the well. They will then be recalibrated; if necessary, the faulty beads will be replaced. Documentation on all recalibra- tion will be maintained in the project files. Surface-water, Quality Monitoring Program The parameters to be included in this surface-water quality monitoring program will be specified by the ADEC at the time the reserve pit permit is issued. The program is designed to detect the migration of waste from the reserve pit. This section discusses the surface-water collection and analyt- ical methods that will be used to implement the monitoring program. These procedures were developed to provide a consistent and reproducible format for conducting the monitoring program that will produce data that is representa- tive of actual site conditions. Surface-water samples will be collected by direct submersion of the appropriate sample containers, with minimal aeration to prevent oxidation of reduced compounds. Prior to collection, the sample bottle will be rinsed with one volume of water from the sampling location. A representative water sample will be placed in a transfer bottle used solely for the field determination of the following parameters: specific con- ductance; temperature; pH; turbidity; and, alkalinity. The instruments to be used for these measurements are presented in Table 13-1. They will be cali- brated in accordance with the Instrument Calibration section and maintained for proper operation in accordance with the manufacturer's instructions. 0056R - 13-2 February 14, 1989 Table 13-1. Field Measurement Instrumentation Parameter Ins trument Temperature Conductivity pH Alkalinity Turbidity YSI Model 33 SCT Meter YSI Model 33 SCT Meter Corning pH Meter Model 140 Hach Digital Titrator Hach Turbidity Meter Model 18900 Equivalent or better instruments may be substituted. Chemical analysis will be performed using only those methods set forth in 18 AAC 60.310(h), Table B. Sample collection, preservation techniques, and holding times will be in accordance with the particular methods of analysis. Table 13-2 is a tentative list describing proper sample handling protocols for potential parameters to be measured for this monitoring program. SAMPLE CUSTODY PROCEDURES Sample custody procedures will be followed through sample collection, transfer, analysis, and ultimate disposal. The purpose of these procedures is to assure that the integrity of samples is maintained during their collection, transportation, and storage prior to analysis. As few people as possible will handle samples. The field engineer will be personally responsible for the care and custody of the collected samples until they are properly transferred to the next custodian. Each sample will be labeled and sealed properly immediately after collection. 0056R - 13-3 February 14, 1989 Anchorage Documentation Sample identification documents will be carefully prepared so that iden- tification and chain-of-custody records can be maintained and sample disposi- tion can be controlled. Forms will be filled out with waterproof ink. The sample identification documents that will be utilized include sample labels, field notebook, and chain-of-custody forms. Sample Labels Sample labels identify the samples. Where necessary, the label is pro- tected from water and solvents with clear label-protection tape. Each label will contain the following information: Name of collector; Date and time of collection; Place of collection; Sample number; Preservative (if any). Field Notebook Information pertinent to the field survey, measurements, sampling and/or health and safety monitoring will be recorded in a bound field notebook. Entries in the field notebook may include the following: Name and title of author, date and time of entry, and physi- cal/environmental conditions during field activity; location of sampling or measurement activity; Name(s) and title(s) of field crew; Type of sampled or monitored media; Sample collection or measurement method(s); Number and volume of sample(s) taken; Description of sample station reference points; Sample identification number(s); 0056R - 13-4 February 14, 1989 Sample preservative (if any); Sample distribution (e.g. laboratory); Field observations/comments; Field measurements data (pH, etc.). Chain-of-Custody Record A chain-of-custody record will be filled out and will accompany every sample and every shipment of samples to the analytical laboratory. This record will provide the documentation necessary to trace sample possession from the time of collection to receipt at the laboratory. The record will contain the following information: Sample or station number of sample I.D.; Signature of collector, sampler, or recorder; Date and time of collection; Place of collection; Sample type; Analyses requested; Signatures of persons involved in the chain of possession; Inclusive dates of possession; Method of shipment, courier name, other pertinent shipping infor- mation. Sample Transfer and Shipment Samples will be packaged properly for shipment and dispatched to the appropriate laboratory for analysis. The shipper will relinquish custody of the samples on the chain-of-custody form and seal it inside the shipping con- tainer. The shipping container will be adequately secured and sealed with evidence tape. A designated sample custodian for the analytical laboratory will accept custody of the shipped samples and verify that the information on the sample label matches that on the chain-of-custody record(s). The custodian will com- plete the laboratory portion of the record, which includes sample condition 0056R - 13-5 February 14, 1989 and temperature. The laboratory personnel will be responsible for the care and custody of samples from the time they are received until the sample is exhausted. Ail data sheets, chromatographs, and laboratory records will be retained as part of the permanent documentation. QUALITY ASSURANCE/QUALITY CONTROL Quality Control Checks The quality control checks represent controlled samples introduced into the sample analysis stream used to evaluate the chemical analysis program for accuracy, precision, and representativeness. Both field and laboratory QC samples will be used in the monitoring program. Field quality control will consist of the collection of one field dupli- cate and one trip blank. The field duplicate will be used to evaluate both the overall sampling program for representativeness of on-site conditions and the laboratory's ability to report precise data. The duplicate will be uniquely identified when it is submitted to the laboratory for analysis. The relative percent difference will be calculated for detected compounds in the duplicate samples. The trip blank will be used to assess the potential for contamination to samples collected for volatile organic compound (VOC) analyses from sample containers, sample transport, and on-site conditions. The trip blank will be shipped in the same container as all field samples submitted for VOC analyses. The laboratory QC checks will include method blanks, duplicates, and matrix spikes at a frequency of one each per sampling event. The method blank is an aliquot of analyte-free water prepared and analyzed with the sample batch to assess the potential for sample contamination by laboratory proce- dures. Duplicates will be prepared by dividing a field sample into two sepa- 0056R - 13-6 February 14, 1989 rate samples, and performing identical sample preparation and analyses on the duplicates. Relative percent difference will be calculated for detected ana- lyres. Matrix spikes will be prepared by adding an analyte of known concen- tration to a field sample prior to preparation and analyses. Percent recovery will be calculated for the spiked analytes. In addition, the laboratory will perform all required method-specific quality control analyses. Instrument Calibration The SCT, pH, and turbidity meters and thermistor strings will be cali- brated immediately prior to use in the field. The calibration procedures will follow standard manufacturer's instructions to assure that the equipment is functioning within tolerances established by the manufacturer. Copies of the instrument operation and calibration manuals will be brought to the field with the corresponding instrument. A record of the instrument calibration will be maintained in the field notebook. The laboratory instruments will be calculated according to the labora- tory's standard operating procedures based upon manufacturer's instructions. ASSESSMENT OF DATA PRECISION, ACCURACY, REPRESENTATIVENESS, AND COM- PLETENESS The QA/QC program will evaluate data based on the quality control checks described above (blanks, spikes, and duplicates). The procedures for evaluat- ing both the field and laboratory QA/QC data are the same and are presented below. The 'evaluation procedure for blanks is a qualitative review of the chem- ical analysis data reported by the laboratories. The trip blank should not contain more than four target compounds with concentrations greater than five times the method detection limit. 0056R - 13-7 February 14, 1989 The method blanks should not contain target compounds above the method detection limit or common laboratory contaminants (i.e. acetone, phthalates, etc.) with concentrations greater than five times the method detection limit. Duplicate analyses will be used to assess precision, a measure of agree- ment between measurements performed using the same test procedure. Relative percent difference will be calculated for detected analytes as follows: where: "D1 - D2" RPD - x 100 (D1 + D2)/2 RPD - relative percent difference D 1 - first sample value D 2 - second sample value To assess precision, the RPD will be compared to performance criteria based upon historical data of the laboratory for a particular analytical method. Matrix spike analyses will be used to assess accuracy, a measure of the agreement between a sample's known value and the actual measured value. Accu- racy will be calculated in terms of percent recovery as follows: where' Percent Recovery X = observed value T = true value X x 100 T To assess accuracy, the percent recovery will be compared to performance cri- teria based upon historical data of the laboratory for a particular analytical method. Representativeness is the degree to which data accurately and precisely represents an environmental condition. 0056R - 13-8 February 14, 1989 Completeness will be calculated upon the completion of each monitoring sampling event using the following equation: valid data obtained Completeness - x 100 total data planned DATA REDUCTION, VALIDATION, AND REPORTING Data collected during the monitoring program will be appropriately iden- tified, validated, and recorded in a report placed on file in Unocal's Anchor- age office. When test data have been reduced, the method of reduction will be described in the reports. Field measurements and analytical results will be entered into a data summary for the reserve pit. Field Measurement Data Validation of data obtained from field measurements will be performed by the field Quality Assurance Officer. Such validation will be performed by periodically checking procedures utilized in the field and comparing the data to previous measurements. Data that cannot be validated will be so docu- mented. The following reporting requirements will be followed for field data: pH' Field measurements will be reported to the nearest 0.1 pH unit. Electrical conductivity' Field measurements will be re~orted to within 10 percent of the total conductivity in umhos/cm~. Water temperature' Field measurements will be reported to the nearest O.I°C. Turbidity: Field measurements will be reported to the nearest 1 NTU. 0056R - 13-9 February 14, 1989 Alkalinity' Field measurements will be reported to the nearest 1 mg/1. Thermistor Strings: Field measurements will be reported to the nearest 0.1°C. Laboratory Analytical DaTa Calculations performed by the laboratories for reporting chemical con- centrations will be performed according to the procedures specified in the methods of analysis. Validation of analytical data will be performed by senior chemists at the respective laboratories and by the field Quality Assurance Officer (or designated representative) for Unocal prior to and following data entry into the data summary and prior to subsequent reporting. The data validation pro- cess includes the specific procedures to be used for evaluating and/or calcu- lating the precision, accuracy, and completeness of the chemical data as described in the Data Assessment section. Should poor laboratory performance be documented from the precision or accuracy evaluations or from detected concentrations in field or laboratory blanks, the Quality Assurance Officer (or designated representative) will notify the appropriate laboratory, and the laboratory will initiate the appro- priate corrective action. REPORTING REQUIREMENTS A report will be prepared that will summarize both the field activities performed and the results obtained. The report will be on file in Unocal's Anchorage office and will be distributed to ADEC and maintained in accordance with permit requirements. These reports, to the eXtent applicable, will include the following: 0056R - 13-10 February 14, 1989 Summary of laboratory data; Presentation of results of QA/QC assessment; Summaries of field procedures; Summaries of field data from field measurements; Comparison of current and baseline data sets. 0056R - 13-11 February 14, 1989 February 2, 1989 Telecopy: (907)276-7542 Mr. Roy D.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe.

CONi:i ENTIAL Drilling Fluid Program The drilling fluid program has not yet been finalized for the Ruby State #2 well but the system most likely to be used is as follows- 70' - 2300' (12-1/4" hole) Conventional spud mud using gel and gelex (bentonite and extended bentonites) for viscosity along with soda ash to treat out calcium. The viscosity would De controlled for hole cleaning. 2300' - 4500' (8-1/2" hole) Low solids/non dispersed system using gel, Cypan, and XC polymer as the principle ingredients. In addition, other ingredients such as sodium bicarOonate (calcium control), caustic soda (PH control), and SP-IO1 and CMO (viscosity control) may be used as required. This mud system is similar to one that has been used extensively on the Monopod and Grayling Platforms in the Cook Inlet recently. Both of these systems, as well as some others being considered are generic muds which are on the approved lists. trf RUBY STATE #2 1980' NSL, 2375' EWL, SEC. 2, T8N, R8E, UM SURFAOE CONFIDENTIAL 16", 70' CONDUCTOR OEMENTED 9 5/8", 2300' SURFAOE OEMENTED 7", 4500' PRODUCTION CEMENTED (IF REQUIRED) PERMAFROST 10 ~"- ..~. :;'}327 · ~ ,* o .
