The closure applications provided the required infonnation describing the history of the site, the present condition of the site, results of any required water sampling and an assessment of the potential risks posed by the drilling waste to human health and the environment. ADEC coordinated review of the closure requests with the Alaska Department of Natural Resources, the Mental Health Trust, Tyonek Native Corporation and private land owners. Public notice requesting comments on the closure requests was published January 19 and 20, 1999 in both the Anchorage Daily News and the Peninsula Clarion. No objections to final closure approval were receiveå in response to the pubìic notice. ADEC has detemlÌned that the reserve pits at this site meet all the closure requirements of 18 AAC 60.440.

SECTIINONE Introduction This closure plan is submitted by Mobil Business Resources Corporation (Mobil) for the inactive reserve pit associated with the West Moquawkie 1 well. It was prepared in accordance with Alaska Department of Environmental Conservation (ADEC) inactive reserve pit closure regulatory requirements found in 18 Alaska Administrative Code (AAC) 60.440, and Interim Site Assessment Guidance for Inactive Drilling Waste Sites (ADEC 1991). Section 1 summarizes historical drilling waste management practices, the history of drilling waste regulations, and current inactive reserve pit closure requirements. Section 2 discusses the approach used to fulfill ADEC closure requirements. Section 3 includes all information stipulated by ADEC closure requirements, and Section 4 provides a summary of the findings and conclusions. 1.1. DRilliNG WASTES AND DISPOSAL PRACTICES This historical overview traces the waste management' practices that have evolved over the last half-century of oil exploration in Alaska. This overview is supplementary to the site-specific drilling records that frequently cannot be located. During the drilling of oil and gas wells, drilling mud is circulated in the drill hole for a number of reasons including: . To bring cuttings to the surface · To cool and lubricate the drill bit and stem · To counterbalance formation pressures, thereby reducing the chance for blowouts · To coat the borehole and prevent loss of fluids to subsurface formations A portion of formation cuttings and drilling mud generated during the drilling process must be managed as waste at the end of each drilling project. Drilling mud is composed of bentonite clay suspended in fresh water, salt water, or oil. A variety of other additives may be added to give the drilling mud specific properties; the choice of additives is dependent on the downhole conditions of the specific well, and they generally have low toxicity. Drilling waste quantities have been drastically reduced over the years through improved drilling techniques. Current drilling programs maximize recirculation of drilling muds to reduce both the raw materials cost and the amount of drilling waste. Until the mid-1980s, drilling wastes from onshore wells were disposed of in on-site reserve pits. Reserve pits were designed to provide secondary containment in the event of a spill or blow-out. Reserve pit structures were built adjacent to the drilling pad. The pit was generally located to minimize the distance between the well and the pit. In permafrost areas, gravel berms approximately three to five feet high were constructed to contain muds and cuttings placed directly on the tundra/land surface. Some of the early pits were excavated, and muds and cuttings were placed below-grade within gravel berms. Where there was no permafrost, drilling sites were often constructed by clearing surface vegetation and digging a below-grade reserve pit.

The remaining reserve pit solids were customarily covered with gravel or native soils before the site was abandoned. Since the rnid-1980s, drilling activities have mainly occurred at the North Slope oil fields. Most on-shore North Slope exploratory wells have been drilled from ice pads. Muds and cuttings are stored in ice pits until completion of the well. After completion, the muds and cuttings are ground and re-injected into the exploratory well, or are transported to development areas for injection or placement in regional below-grade disposal facilities. 1.2. DRilliNG WASTE MANAGEMENT REGULATIONS Throughout the years, numerous governmental agencies and commissions have regulated Alaskan oil and gas exploration and production activities, including the handling and disposal of drilling waste. The table below lists key milestones in the historical evolution of drilling waste management regulations, and entities responsible for regulatory enforcement and oversight. Date Event Pre-1955 United States Geological Survey (USGS) regulates all oil and gas operations in Alaska. At this time, there are no special requirements for drilling waste management. 1955-1959 Oil and Gas Commission is created to regulate drilling operations including disposal of produced waters, non- potable waters, and oil field wastes. 1959-1979 Alaska Department of Natural Resources, Division of Oil and Gas (ADNRlDOG) takes over responsibilities performed by the oil and gas commission. 1971 ADEC is created and given statutory authority for oversight of state environmental matters, including solid waste management. At this time, no special provisions are made for management of drilling wastes. 1979 Alaska Oil and Gas Conservation Commission (AOGCC) is created to regulate oil and gas activities. AOGCC's responsibilities include annual site inspection for suspended wells, and final site clearance for wells that have been plugged and abandoned. 1983 ADEC promulgates 18 AAC 60 for regulation of solid waste. 1983 ADNR/DOG requires that solid waste disposal (including drilling wastes) be discussed in the Plan of Operations for each drilling program. 1984 AOGCC is granted primacy for oversight of drilling waste disposal to the subsurface (Class 1\ disposal). 1987 ADEC revises 18 AAC 60, and adds design, construction, operation, and closure requirements for new reserve pits. 1989 ADEC requires closure of inactive reserve pits. No specific closure requirements are stipulated, but oil and gas operators are required to submit a list of their reserve pits to ADEC within 18 months. 1990 Alaska Oil and Gas Association (AOGA) establishes a Solid Waste Task Force to develop methods for inactive reserve pit closure. An advisory committee is formed shortly afterward, composed of ADEC, industry representatives, and environmental organizations. The industry representatives advocate a risk-based, qualitative decision framework for separating sites with negligible risk from those where corrective action should be considered. 1991 ADEC releases draft reserve pit closure guidance, Interim Site Assessment Guidance for Inactive Drilling Waste Sites. This document contains guidance on recommended number and type of sampling points, analysis parameters, site observations, risk assessment screening methodology, and possible corrective actions. 1993 ADEC releases draft revised regulations 18 AAC 60 for public comment. These draft regulations contain specific requirements for closure of inactive reserve pits.

REGULATORY REQUIREMENTS The ADEC enacted revised regulations for Solid Waste Management (18 AAC 60) on January 28, 1996. Section 440 of these regulations require the following for closure: · Closure plan (18 AAC 60.440(f)) · ADEC approval for closure (18 AAC 60.4400)) · Landowner notification (18 AAC 60.440(k)) If a reserve pit is not found, the closure plan must include documentation of a reasonable search according to 18 AAC 60.440(h). The regulatory requirements for closure are discussed in greater detail in the following sections. 1.3.1.

Landowner Notification 18 AAC 60.440(k) Section 18 AAC 60.440(k) requires notification of private landowners at the time of the pennanent site closure request. ADEC and landowner representatives accompanied Mobil personnel and contractors, as part of the site visit in September 1998. Section 3 of this report lists site visit dates and names of field participants, including landowners. This closure plan will be sent to the applicable landowner(s), as documentation of the closure request. 1.3.4. Closure Plan Addition For Pit Not Found 18 AAC 60.440(h) If the pit is not found, additional supporting documentation must be included: · Names of persons conducting the search · Field notes documenting the search · Recent aerial photograph of the area searched (photograph scale of 1 inch equals 200 feet) The minimum reasonable search shall be one of the following: · Four man-hour search by foot using a 7.5 minute series quadrangle topographic map · One-half hour helicopter survey · Aerial magnetometer survey URS Breiner WDødward Clyde S:\PROJECTS\WCC\986003NA\Template Material\west moquawie 1.doc\8-NOV-98\966011 NA\ANC 1-4 I· I I I I I I I I I I I I I I I I I I /~, /.-..., SECTIINTWO Closure Approach The closure requirements of 18 AAC 60.440 were met using the following components: · Site history and records review · Visual observations made during a site visit · Sample collection and analysis · Assessment including a qualitative risk screening · Corrective action evaluation (if necessary) This section describes the approach taken to ensure that this assessment program meets the closure requirements. 2.1. SITE HISTORY AND RECORDS REVIEW All known and readily available ADEC and AOGCC files and records were researched to locate information about the reserve pit associated with the West Moquawkie 1 well. This information was used to evaluate the site history and environmental setting to fulfill closure plan requirements 18 AAC 60.440 subsections (f)(2) through (f)(4). 2.2. VISUAL OBSERVATIONS The field personnel noted observations on field checklists and in field notebooks, and documented field conditions with photographs. Specific field information required to support the closure plan submittal included: · General site information such as date of visit, field personnel, and weather conditions · Photographs showing site conditions · Biological, hydrological, ecological, geological, and economic observations · Assessment of reserve pit condition · Site map showing site observations 2.3. SAMPLE COLLECTION AND ANALYSIS Sample collection and analysis requirements for inactive reserve pit closure were generally based on the Interim Site Assessment Guidance for Inactive Drilling Waste Sites dated 1991. The regulations were finalized in 1996, five years after the sample collection site visit. The type of samples, sampling locations, and analyses taken are based on all of the following: · Sampling methodology described on page four through six of the guidance · Site specific conditions · Historic information about waste disposal practices at the site · Statistical significance desired to be achieved with the information gathered IIR$ BreIner WøødwanJ CIyr/Ð S:\PROJECTS\WCC\986003NA\Template Material\west moquawie 1.doc\B-NOV-98\966011NA\ANC 2-1 I I I I I I I I I I I I I I I I I I I --------., SECTIINTWO Closure Approach 2.3.1. Surface Water · Measure surface water conductivity and pH around the perimeter of the site. Use 50-foot intervals and take measurements as close as possible to the site. · Collect water samples at the two locations within 50 feet of pad perimeter which have the highest conductivity and/or pH field readings. If two locations can not be identified, take water samples at the two closest downgradient locations. · Collect a water sample for any standing water in the reserve pit or any standing water in drill pad depressions exceeding 50 square feet. Measure pH and conductivity for the sample. · Collect water samples at two upgradient locations at least 200 feet from the edge of the pad. · Collect a water sample of any seepages from the drill pad; measure conductivity and pH of the sample. A water body was considered to be appropriate and was sampled only if the data could be used to evaluate whether a release had occurred from an upgradient reserve pit. For some of the Mobil sites, the only downgradient water body within 1,000 feet of the reserve pits is a flowing stream, or a large coastal water body such as Cook Inlet or Prudhoe Bay. Not only would contaminants from the inactive reserve pit released to these types of water bodies be quickly diluted and dispersed, but potential influence from contaminant sources other than the targeted inactive reserve pit would cause difficulty in fonning conclusions. Thus, no water samples were collected from these type of water bodies because analysis of any data obtained would not be representative of surface water conditions affected by the reserve pit. Analytical results for samples collected from background (upgradient or cross-gradient) water sources are used to assess natural conditions at the site. Background water samples are collected from water bodies that do not appear to have been or could have been adversely impacted by human activities, and have similar characteristics with downgradient water bodies. 2.3.2. Soil · Collect soil samples of reserve pit drilling muds. · Collect one background sample. While not required for reserve pit closure under 18 AAC 60.440( e), discretionary soil samples were typically coll~cted and analyzed when visual evidence of a release was present (e.g., a large area of stained soil, distressed vegetation). 2.3.3. Groundwater · Groundwater will be sampled whenever there are public water systems groundwater withdrawal points within 1,000 feet of the site.

SECTIINTWO Closure Approach 2.3.4. Analyses The samples were analyzed for selected organic and inorganic constituents. Analyses for organic constituents included benzene, ethylbenzene, toluene, and xylenes (BETX), Total Volatile Petroleum Hydrocarbons (TVPH), Total Extractable Petroleum Hydrocarbons (TEPH), and polychlorinated biphenyls (PCBs). Analyses for inorganic constituents consisted of the following metals: aluminum, barium, cadmium, chromium, lead, mercury, nickel, potassium, sodium, zinc, and chloride. Water collected for inorganic analyses were submitted as both unfiltered and filtered samples. Samples were filtered in the field using disposable 0.45 micron filters. Unfiltered samples were analyzed to measure total metals and filtered samples were analyzed to measure dissolved metals. F or chloride, only total chloride was measured. In addition, field measurements of water samples were taken for pH, conductivity, and temperature. 2.3.5. Variations from Regulations Adopted 1996 · The differences between the guidance followed during Mobil's 1991 assessment program and the regulations now in place are relatively minor. Differences include: · The 1991 guidance did not specify a maximum distance for a surface water sample near the reserve pit. Samples up to 50 feet :trom the pad were collected during the Mobil sampling program. The regulations extended the range of perimeter surface water samples up to 1,000 feet :trom the drill pad, and denoted samples within 50 feet as the point of compliance. · The 1991 guidance methodology screened conductivity and pH readings of water around the perimeter of the pad to select surface water sample locations. The regulations specify sampling locations in reference to the reserve pit location. · The regulations added arsenic, nickel and hardness (based on calcium and magnesium analyses) as analytes. The guidance listed mercury, PCBs, aluminum, cadmium and potassium as analytes, not required by regulations. · The regulations have sodium as an analyte, while the guidance listed chlorides and salinity. · The regulations do not require collection of any drill mud or soil samples. · The organic analyses in the 1991 guidance document were Total Extractable Petroleum Hydrocarbons and Volatile Petroleum Hydrocarbons using EPA 8015M meeting the California LUFT program. The regulations required Diesel Range Organics and BETX using EP A 8100M. These methods are all gas chromatograph methods which differ slightly in target carbon ranges that they are designed to measure. 2.4. ASSESSMENT The assessment has two components: chemical data evaluation for compliance point samples, and qualitative risk evaluation to detennine whether a material or probable risk to public health or the environment exists.

SECTIINTWO Closure Approach 2.4.1. Chemical Data Evaluation The chemical data evaluation establishes whether the compliance point sample exceeds applicable water quality standards. Appendix A presents a detailed discussion of how water quality standards were selected from among the relevant water quality criteria. 2.4.2. Qualitative Risk Evaluation The risk screening process from Section III of ADEC's Interim Site Assessment Guidancefor Inactive Drilling Waste Sites (ADEC 1991) was used to detennine risk, since 18 AAC 60.440 does not specify a qualitative risk screening approach. Only the risk screening section of the guidance document (Section III) has been incorporated. Sections I, II, and V of the guidance document have been superseded by the regulations in 18 AAC 60.440 and Section IV was not applicable. Based on discussions with ADEC staff, two modifications to the risk screening guidance were made: · The requirement to evaluate corrective action is eliminated from Step 1, if risk is found to be negligible · An option to perform a risk assessment is added to Step 2, if the risk screening approach indicates significant risk The risk screening process employs a two-step approach to evaluate risk. The first step establishes if there is a basis of concern. A basis for concern is established if evidence of a release or a mechanism for potential release is present (based on visual observations and review of analytical results from water samples), and there is proximity of the reserve pit to biological receptors. If there is none, the risk is determined to be negligible and site closure is warranted. If there is a basis of concern, the second step is to evaluate whether the concern constitutes a significant risk. The finding of significant risk is based on the likelihood of exposure and the likelihood of adverse consequences of exposure. If the risk is not significant, then site closure is warranted. In cases where risk is determined to be significant, a corrective action plan is developed, approved by ADEC, and implemented; or a risk assessment is performed. A risk assessment is more rigorous than the risk screening process described above, including a detailed analysis of all site-specific conditions. Figure 2-1 presents a flow chart of the risk evaluation methodology. Appendix B contains a detailed discussion of the process. 2.5. CORRECTIVE ACTION EVALUATION The site assessment may indicate that corrective action should be evaluated for the site. Corrective action is considered if there is evidence of a release of contamination to water at the point of compliance, and a risk evaluation detennines that there is a material or probable risk to public health or the environment. The responsible party may then: · Propose corrective action and an implementation schedule IJII$ Greiner WøtHIwanJ Clydø S:\PROJECTS\WCC\986003NA\Template Material\west moquawie 1.doc\8-NQV-98\966011 NA\ANC 2-4 I I I I I I I I I I I I I I I I I I I ~, SECTIINTWO Closure Approach Propose a monitoring program to establish whether contaminant levels are increasing or diminishing.

Figure 3-1 is a general location map, and Figure 3-2 is vicinity topographic map showing the site location. Chris Holden and Diana Evans (Woodward-Clyde) along with John Winston (Mobil) conducted a site assessment during August 1991. Al Robb (Mobil), Judd Peterson (ADEC), and landowner Don Karabelnikoff (Tyonek Native Corporation) conducted the site inspection on September 17, 1998. Appendix C contains the field notes for the site visits. 3.1. RESERVE PIT LIST West Moquawkie 1 (API Number 502832003500) was the only well drilled from the pad. Review of drilling files did not establish the existence of a reserve pit. A reserve pit location could not established during the site visits. The pad was level without subsidence or benns which indicate reserve pit location. However, based on drilling practices used at the time when the well was drilled, it was assumed that a reserve pit was used to store drilling wastes. 3.2. SITE WELL AND RESERVE PIT HISTORY This well was originally completed as an exploratory well by Mobil Oil Company in 1970. The current well status is plugged and abandoned. The legal description of the well location is Section 36, Township 12N, Range 12W, Seward Meridian. Longitude/Latitude readings indicated that the revegetated gravel pad is· the location of West Moquawkie 1. A well marker found at the site provided positive identification. The well marker was found in brush in the central/western edge of the pad, cut off from the well head. An area in the center of the pad with wood debris and grout piles is the likely wellhead location. No ADEC or AOGCC records were located during the record search. Figure 3-3 presents an aerial photograph of the site taken during the 1991 site visit. Figure 3-4 is a site map made based on observations during the 1991 site visit. Drill pad boundaries encompass an area of approximately 250 feet by 280 feet. 3.3. SITE GEOLOGY, HYDROGEOLOGY, AND CLIMATOLOGY 3.3.1. Geology As previously stated, West Moquawkie 1 is located on the west side of the Cook Inlet. Geomorphologic features resulting from Pleistocene glaciation are evident throughout the Cook Inlet region, and are responsible for many distinctive land features, including glacial troughs, extensive U-shaped valleys, scoured valley floors, broad outwash plains, and marshy lowlands. Unconsolidated glacial deposits, typical of the lowland areas surrounding Cook Inlet, have been deposited and reworked by three main agents: glacial ice, flowing water in streams or deltas, and still water in ponds, lakes, and marine estuaries.

No specific infonnation about local ground water at the site was available. During the site visit, no drinking water wells were found within 1,000 feet of the drill site. 3.3.2.2. Surface Water There are several small rivers and streams in the area, such as the Beluga and Chuitna Rivers. Tyonek Creek is approximately ~ mile southwest of the site. Area rivers and streams are generally silt laden, with a high sediment load. There are numerous lakes and ponds in the area, most of are frozen from November to May. Area streams may freeze later and thaw earlier than the lakes and ponds. The West Moquawkie 1 site is situated on a relatively level area and surrounded by dense vegetation. There was no obvious drainage pattern at the site, but it is assumed that surface water runoff from the pad eventually drains towards Cook Inlet. Except the Tyonek Creek, there was no surface water evident in the vicinity of this drill site within 'l2 mile. 3.3.2.3. Climatology Coastal areas of Cook Inlet experience weather conditions that are characteristic of a transition climatic zone. Generally, the transition zone consists of a band of varying width between the maritime and continental climatic zones. Climate at the site is variable; it may be continental, maritime, or a combination, resulting in temperatures and precipitation that are more extreme than maritime, but less than continental. Cook Inlet is a major factor moderating area climate. Temperatures seldom rise above 80°F in summer or drop below -30°F in winter. Wind velocities rarely exceed 38 knots and average about 6 knots in lowland areas. Annual precipitation converted to rainfall ranges from 15 to 20 inches. Snow cover is typically present at the site between mid-November and mid-March. 3.4. SITE ECOLOGICAL, BIOLOGICAL, HISTORICAL, AND HUMAN RESOURCES 3.4.1. Ecologicall Biological Resources The West Moquawkie 1 site is located in a spruce/hardwood forest (ADF&G 1984). There is a fairly dense mixed forest in the site vicinity. The plant community is characterized by spruce (Picea spp.), birch (Betula spp., quaking aspen (Populus trem ulo ides ), black cottonwood (Populus balsamifera spp. trichocarpa), and balsam poplar (Populus balsamifera spp. balsamifera) (ADF&G 1984, Fall et al. 1984). Shrubs include willow (Salix spp.), alder (Alnus spp.), rose (Rosa spp.), high bush cranberry (Viburnum edule), and raspberry (Rubus idaeus subsp. melanolasius). URS SteIDel WIHHIwanI Clyde S:\PROJECTS\WCC\986003NA\Template Material\west moquawie 1.doc\8-NOV-98\966011 NA\ANC 3 - 2 I· I I I I I I I I I I I I I I I I I I ,~ SECTIINTHREE Closure Plan Numerous species of birds and mammals occur in the vicinity of the West Moquawkie 1 site (Fall et al. 1984, USFWS 1985, ADF&G 1988). Evidence of moose (Alces alces) was observed during the site inspection. Although not observed, many other mammals are common to the community. Larger mammals include bear (black Ursus american us and/or brown Ursus horribilis arctos), coyote (Canus latrans), and gray wolf (Canus lupus). In addition small rodents such as mice, voles, and bats, and fur bearers such as snowshoe hare (Lepus americanus), red squirrels (Tamiasciurus hudsonicus), muskrat (Ondatra zibethicus), red fox (Vulpes vulpes), weasels (Mustela nivalis), wolverines (Gulo gulo), marten (Martes americana), mink (Mustela vison), lynx (Felis lynx canadensis), river otter (Lutra canadensis), and beaver (Castor canadersis) are found. Bird species likely to be present in the vicinity of the West Moquawkie 1 site include various species of songbirds which may nest in forest habitats such as sparrows (Passerculus sandwichensis Spizella arborea and Junco spp.), warblers (Dendroica spp.), flycatchers (Empidonax trailli and Contopus borealis), swallows (Iridoprocne bicolor), blackbirds (Euphagus spp.), chickadees (Parus spp.), and thrushes (Hylocichla spp.). Raptors include the great homed owl (Bubo virgin ian us ), marsh hawk (Circus cyaneus), goshawk (Accipiter genti/is laingi), bald eagle (Haliaeetus leucocephalus), and osprey (Pandion haliaetus). Upwards of several hundred thousand ducks and geese use the coastal areas of the upper Cook Inlet as feeding and resting areas during spring and fall migration (ADF &G 1988). However, these waterfowl are generally concentrated in the wetlands seaward of the site. Trumpeter swan (Cygnus buccinator) nesting and breeding habitat is located on the east side of the Beluga River, approximately 20 miles northeast of the site (ADF&G 1984). Spawning, rearing, and migration of Dolly Varden (Salvelinus malma), whitefish (Coregonus clupeaformis), rainbow trout (Salmo gairdnerii), and king, pink, coho, sockeye, and chum salmon (Oncorhynchus spp.) occur in streams throughout the area (ADF&G 1984). It is unlikely that these commercially valued resources would be exposed to site reserve pit contaminants, since there was no evidence of a release or mechanism for potential release present. 3.4.2. Sensitive and Endangered Species As shown in Appendix B, Table B 1, certain threatened, endangered, or species of special concern have been identified for Alaska. Although none were observed during the site visit, the following describes the species that may be encountered in the vicinity of West Moquawkie 1: · American peregrine falcon (Falco peregrinus anatum), United States Fish and Wildlife Service (USFWS) endangered species, and Peale's peregrine falcon (Falco peregrinus paelei), United States Forest Service (USFS) sensitive species - depend on cliffs for nesting sites but may be casual visitors or may pass through the vicinity of the site during migration. · Trumpeter swan (Cygnus buccinator), USFS sensitive species - utilize nesting areas located to the east of the Beluga River, and may be visitors to the vicinity of the site. · Osprey (Pandion haliaetus), USFS sensitive species - utilize river, lake and coastal habitats, nest in dead trees, rock pinnacles and on ground surfaces, and may be in the vicinity of the site.

Historical Resources Basic regional industries include oil and gas production, fishing, fish processing, recreation, tourism, transportation and support services, mining, and timber harvesting. Natural gas was discovered in the Beluga River area in 1962. Since that time, refmeries and processing plants have accompanied development of oil and gas fields in the site vicinity. Chugach Electric Association Beluga Power Plant has been in operation since 1963. Recreational and commercial fisheries (both salmon and halibut) are also important economic resources for the Kenai Peninsula. 3.4.4. Human Resources The site investigated in this report is in the northwest portion of Kenai Peninsula Borough (KPB). The village ofTyonek, the closest permanent human settlement, is approximately 6 miles east of the site. Tyonek is a Native community with a population of 148. Located 43 air miles from Anchorage, with no connecting roads, Tyonek is isolated from other populated areas. Tyonek residents participate in subsistence harvest of natural resources, and commercial fishing provides livelihood for some residents. 3.5. PIT CONDITION ASSESSMENT No evidence of a reserve pit was present during the site visit. The wellhead location was not determined, since the well marker was found cutoff on the pad. The surface of the drill pad was covered with gravel, and no standing water was present. Potential contaminant release mechanisms are absent, since no surface water is in contact with or perched over probable reserve pit wastes. 3.6. SAMPLE ANALYSIS RESULT EVALUATION No samples were collected at West Moquawkie 1 since there was no pad or perimeter water present at the stie.

SECTIINTHREE Closure Plan 3.7. SUBSTANTIAL EFFECTS AT COMPLIANCE POINTS There was no surface water present at the drill site perimeter during the site visit. No drilling waste was in contact with surface water. Therefore, mechanisms for potential release and significant migration pathways are absent, indicating that the substantial effects at surface compliance points are limited. There were no drinking water wells within 1,000 feet of the drill site location. Both the 1991 guidance and regulations do not require evaluation of a groundwater pathway unless a public or private groundwater withdrawal system is located within 1,000 feet of the reserve pit boundary. No impacts through groundwater are possible if water receptors are not present. 3.8. QUALITATIVE RISK EVALUATION The qualitative risk screening process introduced in Section 2.4.2 was used to make the risk screening evaluation. The risk screening process uses two steps to make this determination. The first step establishes if there is a basis of concern. If there is none, the risk is determined to be negligible and site closure is warranted. If there is a basis of concern, it is necessary to determine if that concern constitutes a significant risk. If the risk is not significant, then site closure is also warranted. In cases where risk is determined to be significant, a corrective action plan is developed and implemented. Screening methodology is discussed in detail in Appendix B. Results of the risk screening model are summarized in Table 3-1. The inactive potential reserve pit and associated drilling waste are assumed to be covered. There was no visual evidence of contamination associated with the reserve pit. Therefore, no evidence of a release of chemical contamination was present. In addition, no mechanism for release was present since the potential reserve pit was covered, and there was no surface water perched over the probable reserve pit. There are biological receptors present and nearby. The site is accessible by road, and the town of Tyonek is located approximately six miles from the site. Visits by area hunters and local inhabitants are possible. Evidence of site use by wildlife existed; however no wildlife, including threatened and endangered species, was present during the site visit. Although receptors were identified in the site vicinity, any risk posed by the site is negligible, since no evidence of contaminant release or mechanism for release was found. 3.9. CORRECTIVE ACTION EVALUATION The results of the risk model indicate any risk , currently posed is negligible. Therefore, a corrective action evaluation is unnecessaÍy. 3.10. CORRECTIVE ACTION PROPOSAL Since negligible risk has been demonstrated for this site, the recommended corrective action is no action.

SECTIONFOUR Summary and Conclusions The qualitative risk screening presented in Section 3.8 established that there is no basis for concern_ Therefore, Mobil requests that the West Moquawkie 1 reserve pit be closed under regulation 18 AAC 60.440 (f), based on the following: · There is no visual evidence of chemical contamination (e.g., large area of stained soil, distressed vegetation) on or around the drill pad. · The drill site (including the .reserve pit) is assumed to be covered with gravel, and no exposed drilling waste is present. Therefore, mechanisms for potential contaminant releases are absent. · No drilling waste is in contact with surface water. Also, no surface water is located on the pad. Therefore, significant migration pathways are absent, indicating that mobility of possible contaminants are limited. · No drinking water supplies are endangered by the site. · No threatened or endangered species were seen at the site during the site visit, and no economically or commercially important species are endangered by the site. · Representatives of ADEC and landowner Don Karabelnikoff (Tyonek Native Corporation) inspected the site on September 17, 1998.

Sample salinity determines whether to use freshwater or marine aquatic life criteria at a specific site. Freshwater aquatic life criteria are applied where salinity is less than or equal to 1 part per thousand (ppt) [40 CFR 131.36 (c)(4) and 18 AAC 70.040]. However, salinity was not included as a sample parameter in the 1991 field program. Therefore, the application of the marine or freshwater aquatic life criteria are based upon the waterbody type. The site included in this report is inland and not within a marine waterbody. Therefore, the freshwater aquatic life criteria are appropriate for this location. Alaska regulations specify water quality criteria for each protected use class (18 AAC 70.020). As codified in 18 AAC 70.050, waters of Alaska are protected for all usage classes unless the waterbody is specifically excluded. This site is not specifically excluded or reclassified (18 AAC 70.230). Target constituents of concern for the inactive reserve pit closure program are shown in the Alaska Department of Environmental Conservation (ADEC) Interim Site Assessment Guidance For Inactive Drilling Waste Sites (June 1991). The discussion below pertains only to the parameters measured for the reserve pit closure program. Samples were collected to provide data on constituents in the following regulatory groups (18 AAC 70.020): · Toxic and Other Deleterious Organic and Inorganic Substances · Petroleum Hydrocarbons, Oils and Grease · pH · Dissolved Inorganic Substances Toxic and Other Deleterious Organic and Inorganic Substances The Toxic and Other Deleterious Organic and Inorganic Substances-Freshwater group does not specifically state numerical levels for target constituents; rather it incorporates the following by reference: · EP A Water Quality Criteria as referenced in 18 AAC 70.020, Note 5 · Alaska Drinking Water Standards (18 AAC 80) Water quality criteria applicable to this site are presented in Table A.l. The EP A Water Quality Criteria reference encompasses pre-1985 federal water quality criteria documents. Applicable EP A Water Quality Criteria are shown in the A WQS column on Table A.l. Detailed footnotes in Table A.l indicate the source values for the various criteria. The AWQS under 18 AAC 70.020 (b) and 18 AAC 70.040 dictate how the applicable water quality standards are determined from the list of criteria. For target constituents under Toxic and Other Deleterious Organic and Inorganic Substances - Freshwater, the most stringent of the Alaska Drinking Water Standards (ADWS), the EPA Water Quality Criteria for Water, or applicable NTR criterion is selected. The most stringent criteria (i.e., the controlling standard) are shown in the last column. The National Toxics Rule (NTR) criteria (40 CFR 131) imposed selected criteria to bring Alaska into compliance with federal water quality requirements. Not all criteria are applicable to Alaska. In Table A.I outlined values represent NTR criteria which have not been promulgated Woodward-C1yde fì S:\PROJECTS\WCC\9B6003NA\Template Material\APPENDIXS\Append A AWQS.doc\ A-1 I- I I I I I I I I I I I I I I I I I I ¡r-"""', ,~ APpendIX A Water Qualitv Criteria aetennlnadon for Alaska. Therefore, these values were not considered when identifying the most restrictive criteria. Freshwater aquatic life criteria for chromium, lead, nickel, and zinc are hardness dependent. The 1991 field program did not include hardness as a sample parameter. The NTR allows hardness values of 25 to 400 mgIL for hardness dependent criteria. Lower hardness values result in more stringent criteria. Therefore, the minimum hardness value of25 mgIL was used for hardness dependent criteria. Criteria shown in Table A.I are calculated for the minimum hardness values allowed by the NTR (25 mg/L). Petroleum Hydrocarbons, Oils and Grease Total extractable petroleum hydrocarbons (TEPH), total volatile petroleum hydrocarbons (TVPH) , and benzene, toluene, ethylbenzene, and xylene (BTEX) are specified as parameters in the Interim Site Assessment Guidance For Inactive Drilling Waste Sites (June 1991). In 18 AAC 70.020 there is no numerical standard for TEPH or TVPH; however, petroleum hydrocarbons, oils and greases may not cause films, sheens or discoloration on the surface or floor of the waterbody. Total BTEX may not exceed 10 µg/L and benzene may not exceed 5 µgIL. pH pH values characterize the acidity (or alkalinity) of an aqueous solution and numeric standards are present inI8 AAC 70.020. The most restrictive A WQS values for pH are found under the "Water Supply -Aquaculture" classification and specify that the pH of a waterbody may not be less than 6.5 or greater than 8.5. Additionally, the pH may not vary by more than 0.5 pH units from natural conditions. Variation of pH for waters naturally outside the range must be toward the range. Dissolved Inorganic Substances The numeric criteria in this regulatory group principally address total dissolved solids (TDS) content and TDS is not a target constituent of the reserve pit closure program. Conductivity measurements are, however, required. Although conductivity may be viewed as an indirect measure ofTDS, there are no numerical standards for conductivity in 18 AAC 70.020. In 18 AAC 70.020 there is a 200 mgIL standard for chlorides. This value is shown in table A.I. However, the A WQS value for chlorides is being reviewed and the May 4, 1998 public review draft of the A WQS includes a proposed value of 250 mg/L. This would make the A WQS chloride value consistent with the State and Federal drinking water regulations.

I I I I I I I I I ,{~ ,~ Appendix B Risk Screening MethodoloUV Closure plan requirements in 18 AAC 60.440 (f) include submitting a qualitative discussion of material and probable risks to public health or the environment posed by the inactive reserve pit. The regulations do not specify a particular risk evaluation procedure, so the risk screening process in Section ill of ADEC's Interim Site Assessment Guidancefor Inactive Drilling Waste Sites (June 1991) was used Sections I, II, and V of the guidance have been superseded by 18 AAC 60.440. Based on discussions with the ADEC, two modifications were made to the risk screening guidance: . The requirement to evaluate corrective action if risk is found to be negligible was eliminated. · An option to perform a risk assessment was added if the risk screening approach indicates significant risk. The 1991 guidance outlines a screening process for determining if an inactive reserve pit poses a risk to human health or the environment. This risk screening process is qualitative, and uses a decision analysis approach. This is a helpful tool to differentiate drilling waste sites with negligible risk from those sites that present significant risk. The 1991 guidance approach is consistent with current state and federal procedures for performing risk assessments. The risk screening process uses two steps to determine risk. The first step establishes if there is a basis of concern. If there is none, then risk is determined to be negligible, and site closure is warranted. If there is a basis of concern, the second step is necessary to determine if that concern constitutes a significant risk. If the risk is not significant, then site closure is warranted. In cases, where risk is determined to be significant, a corrective action plan is developed and implemented. The following sections discuss each of these steps in greater detail. Figure C 1 presents a flowchart of the risk evaluation methodology. B.1 STEP 1 - IS THERE A BASIS OF CONCERN? The first step in the decision analysis is to detennine if a basis of concern can be established. If there is no pit or the pit cannot be located, the site is declared eligible for closure without risk screening. Some wells were drilled without storing the drilling wastes in a reserve pit. If site records indicate that no reserve pit existed at a site, then there is no basis for concern, and the inactive reserve pit is closed. In some cases it is not possible to locate reserve pits. ADEC specifies that if the reserve pit cannot be located, it will allow closure if the pit cannot be found based on a reasonable search. The definition of what constitutes a reasonable search is presented in 18 AAC 60.440 (h)(I). If a reserve pit is present or likely to be present, then the risk screening process is initiated. Since the regulations only identify compliance points for water (18 AAC 60.440 (e)), water is the pathway for which it is necessary to determine if there is a basis for concern. There are two primary criteria that must be met to establish a basis for concern. The criteria are as follows: Woodward..clyde ., S:\PROJECTS\WCC\986003NA\Template Material\APPENDIXS\APNDB·RISK.doc\15-0CT -98\ANC B-1 I- I I I I I I I I I I I I I I I I I I ,~, ,.-.", Appendix B Risk ScreenlnU'Melhodolouv · Evidence of release of any target constituents in excess of applicable Alaska Water Quality Standards 18 AAC 70, or mechanisms for potential release, and · Proximity of the waste site to any biological receptors. B.1.1 Evidence of Release or Mechanisms for Potential Release The evidence of release criteria is satisfied if a water sample collected on or within 1,000 feet of the reserve pit has levels of target constituents above applicable water quality standards relative to background concentrations. Evidence of release is based upon visual field observations when no samples are collected. Mechanisms for the potential release of target constituents include the following: · A reserve pit dike with unstable sloped, breached, or eroding dikes · Significant negative disturbance of site thennal processes · Standing water in a clearly observable depression on the pad or in the reserve pit · Standing water on the reserve pit cover material Field observations were used to identify if any of these potential release mechanisms were present. Additionally, historical infonnation was used to supplement this visual evaluation. B.1.2 Proximity to Biological Receptors A site is considered to be in close proximity to biological receptors if there is evidence of biological receptors at the site. This includes proximity to nearby towns or villages, or habitat suitable to support wildlife species mown to frequent the area. Certain sites would receive increased scrutiny during the decision analysis process, including those: · With state or federal endangered species habitat · Which supply unique or important food sources · With certain state and federal land designations 8.1.2.1 Threatened and Endangered Species The USFWS lists threatened and endangered species under authority of the Endangered Species Act of1973. The ADF&G lists endangered species and species of concern under authority of the State Endangered Species Law. Table Cl summarizes these species that potentially may be found in areas where AAI has inactive reserve pits. Sites within or near habitat that supports these species will be given additional consideration by the risk screening process. Habitat which supplies unique or important food sources is identified and evaluated on a case-by-case basis.

The Alaska State Legislature has classified game refuges, critical habitat areas, and game sanctuaries essential to wildlife and fisheries resources. Only the Susitna Flats State Game Refuge on the west side of Cook Inlet, and the Yakataga State Game Refuge located along the Gulf of Alaska, west of Icy Bay, contain inactive AAI reserve pit sites. Federal lands designated for habitat conservation include National Forests and National Wildlife Refuges (NWR). There are 16 federally designated areas in Alaska. Only two federal areas contain inactive AAI reserve pit sites: Chugach National Forest and the Kenai National Wildlife Refuge. Inactive reserve pit sites occurring on state or federal lands designated for conservation are given additional consideration by the risk screening process. B.1.3 Establishing a Basis of Concern If evidence of release is found or there is a mechanism for potential release, and proximity to biological receptors is established, then there is a basis for concern that the reserve pit could present a significant risk to human health and the environment. Screening then proceeds to Step 2, to evaluate significance of the risk. Absent a basis for concern, risk is determined to be negligible, and the site is declared eligible for closure without corrective action or further investigation. Note: At this point, the methodology used for these reserve pit closures deviates slightly from the 1991 guidance. The guidance suggests that a corrective action plan be prepared for sites at which there is no basis of concern, and for which risk has been determined to be negligible. This revžsed screening approach allows the site to be declared eligible for closure without corrective action or further investigation based solely on establishing that there is no basis of concern. 8.2 STEP 2 · IS RISK SIGNIFICANT? Step 2 is the decision point to detennine if conditions at a specific site constitute a significant risk to human health and/or the environment. Two sets of criteria are used to make this determination: the likelihood of exposure and the consequence of that exposure. Both exposure and consequence criteria must be met before a site is determined to pose a significant risk. 8.2.1 Exposure Criteria Receptor exposure is considered to be likely if any of the following conditions are met: · Contaminant release mechanisms are significant · Potential for contaminant migration is significant · One or more contaminants are environmentally persistent Woodward.clyde fì S:\PROJECTS\WCC\986003NA\Template MateriaI\APPENDIXS\APNDB-RISK.doc\ 15-0CT -98\ANC B-3 I- I I I I I I I I I I I I I I I I I I ¡~ c~ Appendix B Risk Screening MelhodoloDV B.2.1.1 Contaminant Release Mechanisms Contaminant release mechanisms are considered significant when a target constituent is detected in a water sample from the site (at detectable levels using standard analytical measures), and/or if the site has physical properties that make further release possible. High aqueous solubility and low soil sorption potential are examples of properties which may increase the probability of additional releases. Table C2 summarizes chemical, physical, fate, and persistence infonnation for target constituents. Site specific conditions may increase the potential for releases. Mechanical disturbances of muds and cuttings by wind or wave action, thennokarst activity, or animal disturbance are examples of site-specific considerations. B.2.1.2 Potential for Contaminant Migr2tiQQ~ To directly estimate contaminant migration potential, sample data for locations downgradient of the reserve pit must be available. Migration potential may be indirectly estimated by evaluating the likelihood that a mechanism exists to move contaminated waters away from the contaminant source. Migration mechanisms may include: wind action, freeze/thaw cycles, topography, lack of penna frost barriers, and general area hydrology. 8.2.1.3 Environmental Persistence Environmental persistence is indicated by the current levels of the contamination relative to the age of the pit or natural persistence in the environment. The target parameter's half-life in surface water (Table C2) can be used to indicate its resistance to biological degradation, chemical fixation, mineralization, and photolysis. 8.2.2 Consequence Criteria If none of the exposure criteria are met, then a finding of negligible risk is made. The site is declared eligible for closure without corrective action or further investigation. If any exposure criterion is met, then the risk screening process proceeds to evaluate consequence criteria. Adverse consequences of exposure to target constituents are considered likely if: . Duration or frequency of exposure is sufficient to cause adverse health or environmental effects, and either . Quantity or concentration of contaminant( s) exceeds applicable federal, state, or other protective water quality standards, or contaminant(s) exhibits high acute toxicity.

I I I I I I I I I I I I I I I I I I í~ ,---.. , Appendix B Risk Screening MelhodoloUV 8.2.2.1 Duration or Frequency of Exposure The likelihood that exposure duration and frequency would be sufficient to cause adverse human health or environmental effects are evaluated by reviewing human and wildlife use patterns at an inactive reserve pit site. Human use patterns means detennining the population(s) most likely to use the site (e.g., nearby residents, children, campers/hunters, site workers) and the activity perfonned at the site (e.g., recreation, food-gathering, year-round living). Significance of wildlife exposure is evaluated based on the species most likely to use the site, and the activity for which the site may be used (e.g., migratory stop, nesting, brood-rearing). Site accessibility, such as proximity to airstrips or roads, is an important factor for evaluating human exposure. Surrounding land use and migration patterns would influence the likelihood and significance of wildlife exposure. Other accessibility factors affecting both human and wildlife exposures include the availability of other water resources in the area, snow cover, and the uniqueness of the water or food sources. Groundwater and surface water use influences the significance of exposure. The way the water resource is or could be used (e.g., drinking water supply, contact recreation, subsistence food habitat) directly affects the potential duration and frequency of exposure to a contaminant. Professional judgment must be used to detennine if there is sufficient duration or frequency of exposure to cause adverse health or environmental effects. 8.2.2.2 Quantity or Concentration of Contaminant(s) Exceed Applicable Water Quality Standards Measured contaminant concentrations are compared with applicable health and environmental standards and criteria to detennine if the quantity or concentration risk criterion is met. When only human populations are at risk, health criteria are used. Other environmental criteria are used when comparing to non-human populations. Both human and environmental criteria are used if both human and non-human populations are potential receptors. 8.2.2.3 Acutely Toxic Contaminants The National Institute for Occupational Safety and Health (NIOSH) toxicity rating system is used to identify chemicals highly toxic to mammals. This infonnation is used to detennine whether a target constituent exhibits acute high toxicity. Chemicals with high acute toxicity are those which can threaten life or cause pennanent physical impairment from a low number of exposures. Toxicity is categorized as unknown, not toxic, slight, moderate, or severe. Highly toxic substances are defined as those with: · An oral lethal concentration fifty (LCso) equal to or less than 50 mg/kg · A dennallethal dose fifty (LD so) equal to or less than 100 mglkg · A inhalation LCso equal to or less than 43 mg/kg A similar national rating system is not available for aquatic organisms. Based on the 1991 guidance, an aquatic toxicity LCso value of 1 mglL is used as a criterion for identifying chemicals Woodward-Clyde fì S:\PROJECTS\WCC\986003NA\Template Material\APPENDIXS\APNDB-RISK.doc\1S-0CT-98\ANC B-5 I- I I I I I I I I I I I I I I I I I I r--. ---" Appendix B Risk Screening Methodolouv highly toxic to aquatic life. Additionally, toxicity testing data for species of concern may be used when it is available. Toxicity data for target constituents is presented in Table C3. 8.2.3 Significant Risk Evaluation If either the exposure or consequence criteria in Step 2 are not met, then a finding of negligible risk is made, and the site is declared eligible for closure without corrective action or further investigation. If both the exposure and consequence criteria in Step 2 are met, either a risk assessment is performed, or a corrective action plan is developed. Note: The option of doing a risk assessment is not included in the 1991 guidance document. However, this option was added in the event that a more detailed assessment of the risk at a site is warranted based on data obtained during the qualitative risk assessment. A risk assessment would follow current state and federal protocols for risk assessments. 8.3 REFERENCES Alaska Department of Environmental Conservation (ADEC). June 1991.

It stated that previously unsatisfactory items had been corrected and the location was approved for final abandonment as of September 3, 1974. At this time, the well marker \vas in place, the pit was filled, and the site was clean and fairly level. It also described some standing water and tracks in the filled pit area due to heavy rain during recent work at the location. A subsequent letter from USGS to Mobil Oil Corporation dated 10/16/75 agrees with the approval of final abandonment at this location, but informs that the land on which the well is located has been transferred to the State of Alaska and the final abandonment approval would have to be made from the appropriate State agencies. Another letter from DNR dated October 23, 1975 confirms the satisfactory condition of the Beli Unit 1 location. Field notes from an August 12, 1991 investigation by Woodward-Clyde located the reserve pit on the southern portion of the pad. It was covered with gravel which had some depressions that contained water. There was no evidence of seepage or overflow to the surrounding areas and the pit dike appeared to be intact and stable. There \vas no petroleum hydrocarbon odor, stains, or sheen evident anywhere on site, either on soils or \vater. Chemical analysis of the water from each of the two ponds in the reserve pit sho\ved al] constituents tested to be within Alaska Water Quality Standards except for Aluminum, \vhich exceeded the standards slightly. The eastern pond exceeded the drinking standards for aluminum by 0.2 mg/L and the limits were exceeded in the western pond by 0.4 mg/L. The aerial photo shows the site to be clean and partially re-vegetated. Another site photo indicates vegetation on the reserve pit to be similar to the natural vegetation surrounding this location. The topographic map shows Beli Unit 1 to be located far from any areas of human activity or means of access. It also shows that the site is not located in an area that is likely to be eroded by rivers or tides, because of distance from water bodies.. The 1991 field notes indicate that there was no evidence of human activity or habitation which could be affected by the site, such as dwellings or water wells. Conclusion: This reserve pit should receive Agency closure without further action since the reserve pit has been filled in, no mechanism for any waste to be exposed to the environment, and the site is in an area that is not susceptible to future disturbance of covered waste. The site has made no impact to the surrounding vegetation or the human environment. Aluminum was the only analyte (from the sampling required with the 1991 ADEC reserve pit closure guidance) which slightly exceeded A WQS. This detection may indicate some contact of water with waste, but it is not conclusive since other common drilling waste constituents were not detected. Because the aluminum is only slightly higher than the stand~, ~tŒsE I V E D unlikely the A WQS would be exceeded at the point of compliance. This location has begun to re-vegetate naturally and any further activity at this site may disturb natural resto)£tror[~ J 7{i00 processes. S '\PROJECTS\WCC\9660 12NA \CLA IT ACH. DOC 0 I-I 0-97 .

Tuesday September 9, 1975 - We departed Texaco's Kad River location at 3:12 PM heading east for the Canning River area but shortly before reaching the river we turned south and soon found Mobil's location. Mobil's Be1i Unit No.1, Sec. 8, T4N., R23 E., UM.; P&A 6/24/73; F-034405 I made two inspections of this location last summer and had given Mobil my approval on September 3, 1974 (see report of 9/14/74). The USGS and the BLM people had not revisited the lease since then. We landed, after circling and making the usual pictures. 1. took Photo No.8 from the air which shows almost all of the well site pad and the camp area pad. The old pit area is still the wettest portion of the pad with some water stand- ing in ruts. After landing, I tooK Photo No.9 showing the wellhead marker with gravel mounded over the casinghead in the background looking across the worst part of the reserve pit area which still appears to be in good shape and very similar to the way I left it on my previous visit. Photo No. 10 is a por- tion of the mousehole pipe with rocks in it sticking up near the mound of dirt by the wellhead marker. We kicked some more gravel and dirt over this. Every- one was well satisfied with the condition of this location, so we soon took off and headed southeast again. immediately after leaving the location we flew over a hilltop and found the gravel pit that had been used to build the location. I took Photo No. 11 looking north across this gravel pit area. There is some snow obscuring the ground but it appeared in relatively good shape. This is the second of 14 well locations inspected on federal leases ~hich are to become state leases. In discussing this location with Bill Wunn~ke we ~reed that nothing further needed to be done at this locatinn--- S:-..'

OF ENVIRONMENTAL CONSERVATION Telephone: (907) 465-5162 Fax: (907) 465-5362 April 24, 1998 170-0S3 Mr. Albert Robb m Mobil Business Resources Corporation P.O. Box 650232 Dallas, TX 75265-0232 Reference: Issuance of Approval for Final Closure for Seven Inactive Reserve Pits Dear Mr. Robb: The Alaska Department of Environmental Conservation (ADEC) has completed review and public notice for the Mobil Business Resources Corporation closure applications and requests for final closure approval for inactive reserve pits. The closure applications, received January 21, 1997, provided the required information showing that previous closure was approved by a state of federal agency and that water does not accumulate in direct contact with drilling waste. The documents also provided acceptable aerial photographs of the site and a statement explaining why further action is not necessary to protect public health or the environment. ADEC coordinated review of closure requests and field inspections of the sites with the Alaska Department of Natural Resources (DNR), Bristol Bay Native Corporation, Tyonek Native Corporation, the Kenai Peninsula Borough, and fee simple private land owners. Public notice requesting comments on the closure requests was published January 30 & 31, 1998 in the Anchorage Daily News and February 2 & 3, 1998 in the Peninsula Clarion. No public comments were received in response to this public notice. ADEC has determined that the reserve pits at these sites meet all the closure requirements of 18 AAC 60.440(b). Closure Approval Under authority of 18 AAC 60.440(c), ADEC grants final closure approval to Mobil Business Resources Corporation for the inactive reserve pits at the following seven drill sites: Well Name 1.

Three Mile Creek State #1 Terms and Conditions This final closure approval is subject to the following tenns and conditions: 1) In accordance with 18 AAC 60.440(1), the Department will require additional investigation, assessment, monitoring or remediation if new infonnation regarding conditions at the reserve pit facilities indicates that further actions are necessary to protect human health or the environment. 2) The approval granted by this letter is for the inactive drilling waste reserve pit(s) only. Closure for the pad as a whole (if required) must be coordinated between the owner/operator and the appropriate land owner/manager. Any person who disagrees with any portion of this decision may request an adjudicatory hearing in accordance with 18 AAC 15.200-310. The request should be mailed to the Commissioner of the Department of Environmental Conservation, 410 Willoughby Avenue, Suite 105, Juneau, Alaska 99801-1795. If a hearing is not requested within thirty (30) days of the date of this letter, the right of appeal is waived. Please remember that even if an adjudicatory hearing has been requested and granted, this decision remains in full effect during the process. Sincerely, .-../} /ì ,~1 ,., - ./ ~ _ / t:" 1,-, . :.
