I’m trying to find any information on the drill stem tests conducted in Itkillik Unit 1. The AOGCC well history file is very sparse, only 29 pages long. And I’m in Texas so I can’t go review the logs, but the data list seems complete with no mention of any drill stem test info. From the 10-407: I appreciate any assistance you can provide. And if Hilcorp doesn’t retain the data, any suggestion of someone else I can ask would also be appreciated.

The test wasisucc)essful with no plugging of the tools evident in the chants. There was a good air blow to surface immediately after opening the tool, followed by gas; in 5 mins. It is evident from this test that the formation is tight, i,ea, it _ has no permiability, but that it does contain gas un&er moderate pressure. No water was evident in the drilling fluid recoveredkfrom the drill string, The low methane and ethane counts -.in the recovered mud samples are believed to be caused -.'by the escape of these lighter gases; before the mud samples could be analyzed, A sample of gas: was: caught after 20 minutes of surface flowand is, being sent to London for analysis:. This sample was caught at the end of the flare line at a temperature of +100 F, DEPT.

The list was addressed to your office and dated January, I2. 1995. Four sites were inadvermnttv omitted by ADEC ~om the list of closure approvals, and two additional omissions were identified by the Department while reviewing Mr. Lowe's letter. Furthermore, four sites recei:,ed conditional closure status contingent upon surfac~ rehabilitation: three or. her locations were mentioned, as candidates for further remedial action. Surface work is complete or in pro~ess ar these latter sites and the/r stares is now subject :o further review bv the Department. This corres~)ondence describes our review procedures, puts forward the Department's f'mdings, and takes action upon the closure requests. The sites have been reviewed in accordance with the ,4JDEC Interim Site Assessment Guidance for Inactive Drilling Waste Sites. June 1991. The third draft of Alaska's new Solid Waste Regulations. i 8 AAC (50. is currently under review, and this third draft contains a chapter on Inacuve Reserve Pit closures. The closure criteria in this proposed re~m~lation parallels the closure criteria in the 1991 Guidance Document. Closure under the 1991 Guidance Document should constitute closure under the proposed Solid Waste Regulations. The review procedures include an evaluation of the risk screening assessment required in the 1991 Guidance Document. and is summarized in our previous correspondence ~'Januar),' !2. 19953. Briefly, the significance of risk to local receptors is evaluated through study of contaminant release, exposure criteria, and consequence criteria. Mr. Steven D.

Drilling Waste Disposal Facilities on the North Slope. These sites have been reviewed in accordance with the ADEC Interim Site .*ssessment Guidance for Inactive Drilling Waste Sites. June i991. This correspondence describes our review proceaures, puts lo,yard the department's findings, and takes action on the r:auests. Currently, the second draft of Alaska's new Solid Waste Regulations. iS.AAC 60. are under review, and this second draft contains a chapter on Inactive Resetwe Pit closures. The closure criteria in th/s proposed regulation parallels the closure criteria in the 1991 Guidance Document. Closure under the 199! Guidance Document should constitute closure under the proposed Solid Waste Regulations if they are adopted as current drafted. The Review Procedure The cmaiitative risk screening procedure required in the above referenced document determines whether a site presents negligible levels of risk. or if it is a significant risk generator. A decision scheme is then employed to establish { 1') whether or not there is a Mr. Steven D. Tavior January 12. 1995 BPXA Inactive Drilling Waste DisDosai Faciiitv Closure Approval basis of concern, and (2') whether or ntt a. waste site :s iikeiv to sresent si2nificant risk to human or environmental receptors. - . The first step in this screening criteria is establishing a basis of concern: "If the waste site has released contaminants or there are.mechanism for potential releases and there are receptors nearby, then. there may be cause for concern, and the waste site should be studied further." and "If there is no release of contamination or no mechanisms for potential releases and there are no recestors nearby, then there is not a basis for concern and the waste site should be considered ciosed." The criteria that are measured a: a waste site to sausfv :ne above lo~ical ar_*uments are: Evidence or' release of ~"~ '~; ,.n,~mn.~. contamination ar the waste site in excess of Alaska Water Quality Standards :'or one or more target comsounds, or Mechanism for potenuai release, and Proximity of the waste site to bioio~icai recestors. If either of the first two criteria and the last criteria are met. there is a basis for concern, and before proceeding with Step" a corrective action plan shall be prepared for the site which shall idenufy alternative wavs to correct or mitigate the basis o~' concern, prevent its recurrence, and seiect a srefe,,-red approach. Corrective action alternatives shall be described at a conceptual level, and the seiection or' a preferred approach shall be based on balancing protectiveness with imstementabiiitv and cost-effectiveness. The second step determines whether contamination at a waste site present a risk to receptors that is si2nificam, tf risk is found not to be significant, it is considered to be "negligible." The finding or"-si2nificant risk is based on the likelihood of exposure and the likelihood of adverse consequences of exposure: "For risk to be considered significant, the receptors must be vulnerable to exposure, and the consequences of exposure must be 'adverse' to human or animal health or the environment." and. conversely, "If exposure is unlikely or the conseauences of exposure are not 'adverse.' then the risk is negligible. Xlr. Steven D. Taylor Januarx' 1.2. 1995 BPXA inactive Drilling Waste Disposal Faciiitv Ciosur,, Ar~provai tf risk at a waste site is si2nficiant, then corrective action should be taken. The criteria that are evaluated at a waste site to satisfy tt-',e tomcai armaments above .,,re exposure criteria and conseauence criteria. Exposure Criteria: Receptor exposure is considered to be likelv when: Contaminant release mechanisms are iud~ed ~:znificant . or Containmem migration is judged significant. One or more contaminants are envirorumenrzily persistent. If exr~osure is found to be uniikeiv, a findin*_ of ne_~i.i~ible risk is made on the basis of absence of a iikeiv exaosure item and the action aian is evaiuated under the Impact/Benefit Evaluation stea. The purpose of this step is to dete,,'-:'nine whether the benefits of taking a corrective action would be greater than the impacts of taxing such a corrective action. If any one of the exposure criteria are met. a finding is made that exposure is likely. Further screening then continues to evaluate Consequence CNteria. Consequence Criteria: Adverse consequences of exposure to contaminants from reserve pits are considered to be likeiv when: ia} The duration or freauencv of exposure is sufficient to cause adverse health and environmental effects. This is evaluated bv reviewing human and wildlife use patterns at a given waste site, waste site accessibility, and ground and surface water uses, and either; (b) The quanti~' or concentration of one or more contaminants exceeds pertinent federal or sate water cmalitv criteria or standards protecting health and/or the environment. Measured contaminant concentrations in the water will be compared with health and environmental standards and criteria for each target contaminant, to identify' exceedances. When only human populations are at risk. health criteria are used. When only populations at risk are nonhuman {e.g., z~sh, wildlife, vegetations, environmental criteria and standards are used, or: (c) One or more contaminants e,'daibit high acute toxiciw. The NIOSH toxicity rating system [NIOSH 1974¢ will be used to identify contaminants highly toxic to mammals. This Mr. Steve,n D. Tavtor Janua~' 1"_. 1995 BPXA Inactive Drilling Waste Disposal Facility Closure Approval information ;,,'ii! be used to dete,wnine whether a target comoound exhibits acute high toxicitY. If the duranon and freauencv of exposure is insufficient to cause adverse effects, there is no need to evaluate the other two conseauence criteria, and a findin2 of netiihible risk is made. If the duration and freauencv term is sufficient, but neither of the other two conseauence criteria are met. a finding or' negiigible risk is made. The action plan is then evaluated under the imaact.'Benefit Evaluation step. If the duration and freauencv of exposure is dete~,'-mined to be sufficient to cause adverse effects aha e:~qer or' the other two conseauence criteria are satisfied, then a finciint is made that adverse conseauences are iikei,,,, and the risk at a waste site is said to be si_onificant. If the screemng indicates that r:sk is significant, then the responsible part3.' shall rroceed with implementations of con-ecti:'e actions.
