":'. .:, File No..300.15.217 Re: Amoco Production Company - Drilling Waste Reserve Pits Final Closure Approval of 25 Inactive Facilities The Alaska Desartment of Environmental Consem'ation (ADEC) has evaluated ,/our co~es=ondence, dated Februav: 19. 1992. requesting closure of 29 .aa-noco Production Company ~.~ocol inactive reserve pit disposal facilities. Surface evaluations were pe,~ormed at the sites in ! 989 and ! 990. T:2s corresvondence describes our review procedures, puts forward the De:~trnent's findings, and takes action upon the closure request. The 29 facilities were assessed by Aa'noco prior to the issuance of the ADEC Interim Site -~ <sessment Guidance for Inactive Drilling Waste Sites, June t C~Ol. The ne:v Alaska Solid Waste Reguiations. 18 AAC 60, became err%ctive January. 28. 1996 and contains a chapter on inactive reset'ye pit closures ~I 8 A-kC 60.440). The closure criteria in the new regulations parallel the closure criteria in the 1991 guidance document, and the review procedures require a discussion of :he risk screening assessment as required in the 1991 document. Briefly, the significance of risk to local receptors is evaluated through study of contaminant release, exposure criteria, and conseauence criteria. The i98%1990 Arnoco assessment program included acquisition of numerous (10-30) shallow cores within and adjacent to each drill r~ad. sampling of the cored material at five-toot intervais, and installation of monitorina ,.,,'ells on several facilities from which shallow groundwater was encountered while coring.

Napamk Creek No. 1 Concern is expressed bv the U.S. Fish and Wildlife Service over surface conditions at Nar~aruk Creek No. 1. which appear to be impacted by abandoned drilling-related trash and eaui=ment. Of particular :.oncem are references in the original assessment document to drums, batteries, and sac:cs of dr-ilIinz mud and/or mud additives. Recent documentation {'8/19,,'96'~ sur~otied bv Amoco to the ADEC demonstrates that further clean-uo was ?e:,'ormed after ',.he assessment date. and the de~ris was removed or disr~osed of properly. Tinis ir.formation has been forwarded to the U.S. Fish and Wildlife Se,vice for review. Tvonek State No. i Cohos:., is exaressed bv the Contaminated Sites Section of ADEC over potential groundwater contamination fi'om buried rese~'e pit wastes at the Tyonek Stare No. 1 location, especially with freauent summer habitation of the site by Tyonek village residents. Evidence from the i990 monitoring well data indicate substantial water quality, exceedances with respect to c.hromium, lead. barium. TPH. and the BTEX components. Subsequent analyses ::rom saint>les collected in 1991 and 1993 indicate the BTEX concentrations are dimirushing: however, metal analyses were not reported and TPH concentrations appear to increase significandv in 1993. Final closure approval of the reserve pit may be granted under l $ AAC 60.4400)(5) -if the owner or operator demonstrates that water pollution in the affected water body is dimimshing~. Therefore. it is requested that ,~d'noco re-sample the two monitorin*_ wells to verify that BTEX. DRO. and metal c0ncentrarions are dimimshin*_. Ac:.urate analyses of the metal and hydrocarbon (DRO and BTEX) ..~ ir. ~,.n A. Bovce f Semernber 6. 1996 :omsonents listed in Table D of section 18 AAC 60.440. with the appropriate analytical memodology, are recuired prior to closure.

TEe decision of :he ADEC is :o "Deny" c!osure approval of the following facilities ~til inrb~ation reauired to address ~e conditions is =rovided to the Dep~ment. The ~sessment ~'-~~ ~,..~.~ for these sites were not included for pubiic review: this ~roc, ~ss will be initiated upon ~';~;;-=- of~e seeciKc conditions. Ahtna Inc. No. 1 Barium. TPH. and BTEX concentrations in soil core's from the .X&tna Inc. No. i site (core '.ecations 5. 6. 12. !35 indicate drilling waste is present at or within a five foot depth within tine reserve pit depression. Standing water occurs within .the depression in possible contact with fine waste. Conseauenrly. closure of the reserve pit under i8 .<-kC 60..-!.40(j) requires sarnpiing and analysis of surface water at the site as' specified in Tables C and D. Water :'rom sends on the nor'& and south ends of the rese,,we pit and at background and down- ~.ame,t locations should be sam, sled. The analytical dam. an appropriate cmaiitative risk assessment, and analysis of feasible corrective action as outlined in 18 :X_-kC 60..2.40(f)(7,-10) are required prior to closure. Chuima River State Further information is required to reach a final decision on the closure status of the Chuima Kb'er State location. Hi.~h concentrations of BTEX (Level A and B soil exceedances), ~ ~ H. and several me'als in the rese~'e pit chilling waste exist at or within .~-!0 ti depths, and may contact the large pond of standing water. Groundwater from monitoring wells around the pit identified variable ieveis of pe=oieum hvdrocartmns. Large concentrations' ..~-f TPH at station MW28 (TPH=58 mg.,'I) and MW9 ~TPH= t0 mg,,'I) were observed in the ~995 data. ti'he down-gradient occurrence at .MW9 suggests that TPH-denved organics may be migrating outside the pit area. Groundwater metal anaiyses were not included. Surface water analyses from the 1993 program identified trace levels of the BTEX components: eievated levels of barium and lead ~'Pb=25 ppb) were detected in a 1989 surface sample. The Desarnnent re=uests that further sampling and analvses of the resuired metal and hydrocarbon components listed in Table D (18 AAC 60.440) be pert'ormed at the site, utilizing analytical me~odolog7 specified therein. At least one surface water sample from location SW4. and three groundwater samples from M-W9. MW17, and MW28 are reauested. The Deparnnent recommends that you bail/purge the monitoring wells prior to sampling and use a field-filtration method to eliminate particulates r'rom the groundwater ~i.e. measure only the dissolved metal concentrations'). Final closure approval of the site should then be possible under 18 A-kC 60.4400)(5) if the contaminant levels are indeed diminishing. Final closure approvai will be granted after it is demonstrated to the ADEC that drilling was:es within :he mis are not actively contaminating surface water or groundwater at the sites. Mr. D. A.

Attached is a list of all intervals sampled and examined -- 159 ditch and 5 core samples. In most cases there are two samples to each prepared slide. An analysis of the microfossil content shows the following general results: 50-6170' Upper Jurassic. Foraminiferal genera present include: Bathysiphon, Ammobaculites, Spiroplectammina, Haplophragmoides, Trochammina, Gaudryina, Recurvoides, Lenticulina, Astacolus, Dental ina, Eoguttulina, Conorboides. Both nassellarian and spumellarian radiolarians are present with spumellarians dominant in numbers. 6170-?14,360' Probably Middle Jurassic. Foraminiferal genera present in addition to those listed above include: Ammodiscus, Verneuilinoides, Textularia, Nodosaria, Lingulina, Marginulinopsis. Nassellarian and spumellarian radiolarians are present in most samples and abundances of both kinds are very high in many samples. Inoceramus fragments are present through most of this interval. Four core samples between 7405 and 7425 feet were essentially barren of organic material. One core sample at 12,100-12,110 feet contained rare arenaceous foraminifers', some nassellarian radiolarians, and fragments of Inoceramus. Abundant pyritic fragments present may represent remains of spumel~arlan radiolarians.

O. Box 779 Anchorage, Alaska Reference is to a telephone conversation this date between your Mr. Thomas Marshall and Amoco's Bill Halvorson regarding Amoco's plans to run casing in subject well. Attached are two copies of USGS Form No. 9-331 detailing the proposed changes in the drilling program. Hole problems which developed recently have resulted in the decision to log and run caSing at current TD, some 569' above the TD proposed by our letter of September 28, 1973, File: WMJ-522-WF. Please no'te that we propose to reduce mud weight to 12 ppg prior to cementing the 7" liner and to set the liner packer at 7800' to cover all 9-5/8" casing set below the theoretical collapse depth for 43.5# P-Il0 in 9.5 ppg mud, assuming a safety factor of 1.125.

ALAS�J- A SUX'•.ARY OF HISTORY In late 1967, Amoco was given approval by the U.S.r,.S. to form the Nelson River Development Contract. In early 1968, Amoco began an onshore seismic pro?ram west of the Caribou River and generally north of the David River fault (Encl. 1) to the Bering Sea, in which 112 miles of: 600% seismic was obtained. In addition, a geological field party was sent into the area during the summer months in order to Lather litho-stratigraphic, paleon-;. tologic, and structural data. -In the following year, 82 miles of 600% t seismic was shot east of the Caribou River to Herendeen Bay. Prior to drilling any wells, Amoco entered into a joint operations agreement with Standard of California covering the area north---.' of the David River fault. Subsequently, three wells were drilled: Pan Am David Riv er,#l-A and the Pan Am-SoCal USA Hoodoo Lake Units #1 and #2. All three.wells were unsuccessful. CONCLUSIONS Jk 1. The David River fil-A indicated the presence of gas in the Lower Tertiary and Upper Cretaceous and greatly expanded our knowledge of the stratigraDhy. 2. Our optimum mappable horizon is an unconformity between the Miocene and'Oligqcene based on well -to -seismic ties of the David River #1-A and Hoodoo Lake P2. 3. The interpreted Cathedral River structure is breached to the Upper Jurassic- Naknek Formation. The thickness and character rocks which underlie this feature are unknown due to lack o nearby AUG 24 197.1 Conservation Diriln, U.S. CE0L0('1(',1,L Su ..,E) Andi,va9C.

SUMMARY OF EX' LCRj.TORY WELLS The Dav'.d River Al was spudded on 11/6/68 in Section 12-T50S- R30W, SM. Due to hole problems, the well was abandoned at 2300 feet and the rig was skidded to a new location. The David River #1-A was spudded en 12/30/68 and was drilled to a TMD of.13,769 eet, with numerous mechanical difficulties involving several whipstocks. The well bottomed in the Upper Cretaceous'Chignik Formation and was PEA -on 8/14/69. The top of the Chignik was encountered at a measured depth of 12,200' The strata drilled is composed of shale, siltstone, sandstone, conglomerate, and coal, and is interpreted as having ` been deposited in .a, predominantly nonmarine to near -shore shallow marine -' environment Sample oil and gas shows were recorded intermittently from 10,000 feet to TD The mud gas chromatograph detected methane through butane while drilling this section. Three drill -stem tests were run: two in the Lower Tertiary and one in the Cretaceous. All three tests -flowed from 5 to 10 MCFGD and 310-548 EWPD. The waters are brackish with salinities of 6100-8900 ppm. Due to mechanical. difficulties, the log quality was such that reliable Porosity and water saturation calculations could not be obtained. A dip meter survey was run cnly from 11,800 feet to TD. Lack of rPt;ahto dipmeter and hole deviation data precludes calculation of true stratigr ohi.c thickness. r AIiG 24. 197' Consprvati'1)i, U.S. GEOI.00aCAL Aneborage. l =:.e ;oin ....-SOCal USA hoodoo Lake Unit i;l (Gcec. 21 o:-. 12/17/69 and bottvc;ed In"addle , io;ene strata - at a ix'P of 049 =eec, t:o shows were noted in this well. A drill -stem test o-" the loser sands recovered 7000 feet of formation water (sal. = 4200 ppm mud, and sand. The well penetrated a basically marine, highly sandy section with good to excellent porosity and permeability based on sidewall cores, logs,`and drill -stem test results. The well was PEA on 1/9/70. The second hoodoo Unit well was located approximately three miles southeast of the first Hoodoo well. The objectives of this well were to re -test the Lower Tertiary rocks, which had gas shows in the David River #1-A, and to test the Upper Jurassic strata. The joint Pan Am- SoCal USA Hoodoo Lake Unit' #2 (Sec. 35-T50S-R76W) was spudded on 2/13/70 and bottomed in the Lower Cretaceous -Upper Jurassic Staniukovich Formation .at a TMD of 11,243 feet This well was PEA on 4/28/70. The top. of the Oligocene is at a TMD of 2060 feet, which is 6000 feet higher than in the Hoodoo #1 well. The base of.the Tertiary is at a TMD of 7770 feet and overlies the Upper Cretaceous Coal Valley Member.. Three drill -stem tests 5 were run: two in the basal Tertiary sands and onein the Upper Cretaceous. All recovered mud or water -cut mud, and a light oil scum was present in two of the tests. The Lower Cretaceous Herendeen Limestone is tight and sandy, and no shows were recorded. Approximately 1600 feet of the Staniukovich For-mation was drilled and consists of a tight, feldspathic sandsto.e-siltstone. Several andesite intrusives were cut, and the well bottomec in a similar intrusive of Lower Eocene age. In its outcrop area, the Staniukovich has fair porosity and permeability; however, well this section is tight.

Designation of which manufacturer's equip- ment will be used to be determined after selection of drilling contractor. B. BOP Testing Procedures and Frequency Ram-type blowout preventers shall be tested to the rated .work- ing pressure of the BOP stack assembly when initially installed; before drilling out after each string of casing is Set; not less than once each w~ek while drilling; and following ~any repairs that require disconnecting a pressure seal in the assembly. The Hydril- type blowout preventer will be tested to its rated working pressure after initial installation, and to at least 50 percent of rated working pressure with the same test frequency as the ram-type preventers. -3- While drill pipe is in use, ram-type preventers will be actu- ated once each trip to test for proper functioning. The Hydril- type blowout preventer will be closed on the drill pipe at least once each week to test for proper functioning. Rig supervisor will schedule BOP drills to familiarize crews with operation of BOP equipment. ® Drilling Fluid Program A. For Depth Interval O- 2000': Plan to use bentonite-fresh water low solids non-dispersed mud system, utilizing Amoco Drillaid 420. B. For Depth Interval 2000'-10,000': Plan to use bentonite-fresh water low solids non-dispersed mud system containing Drillaid 421, Drillaid 425, and Drillaid 405.
