BACKGROUND: OPLAN 600-77 tasks the HQS JTG with the responsibility for providing recreation services support to the cleanup project personnel on both Enewetak and Lojwa. DISCUSSION: a. The most significant participation is in outdoor sports. The lst-1979 softball season was completed on 20 May 1979 with HQJTG beating the Lojwa Officers in the Championship Game. The CJTG presented individual and team trophies to Lojwa Officers and HQS JTG. A basketball season is tentatively scheduled to begin in June. b. Leathercraft continues to be the most actively supported craft activity. The Photo Lab has seen increased usage as the talents of the Motion Picture Photographer are used to assist interested personnel in developing and printing photographs as well as processing of slides. c. USO Shows are popular. The last show, George King and the Fellowship on 9-10 May was seen by over 450 people here and at Lojwa. The next show is Sunshine Express scheduled for 4-5 July. Free movies are well attended each night - the new speakers installed at Enewetak theatre have improved performances. · Mov.ie projectors are adequate but due to the harsh environment breakdowns are frequent. AFRTS programming is in an expansion phase as increased emphasis is being placed on Command Information topics and safety announcements are broadcast each week in response to RSAIT recommendations. d. Water activities are very popular. At present, two sunfish are operable and are located at Lojwa. · Two sunfish were recently surveyed and destroyed after inspection certified that these boats were unsafe. The four hobie-cats were painted and three are operational. The swimming pool at Enewetak has been repaired. The chlorinators removed,after Typhoon Alice to assist life support system are back at the pool; · A diving board was installed, the deck painted and the .pool thoroughly cleaned. 0 0 FCRA MAJ Haraszko 1S \fay 1979 i FACT SHEET SUBJECT: Military Award Status PURPOSE: To provide the current awards status for awards submitted for personnel assigned or attached to the Enewetak Cleanup Project. BACKGROUND: Enewetak Atoll Instruction 1301, Military Awards and Decorations in consonance with FCDNA Instruction 1348.16 and DNA Instruction 1348.lC established procedures for submission of awards for military personnel assigned or attached 'to the Enewetak Cleanup Project. DISCUSSION: a. Recommendations for awards submitted for personnel assigned to HQJTG and those Joint Service recommendations submitted by Element Commanders on behalf of their personnel are reviewed by an Awards Board at Enewetak for content and substance. Recommendations are provided to the Commander, Joint Task Group and if approved are sent to Field Command for further processing. b. During the past few months the number of recommendations from Element Commanders has risen considerably as a result of increased emphasis on the p·art of the Commander, Joint Task Group. c. Timely feedback of results from the Awards Board meetings held at Field Command has assisted in maintaining and monitoring status of awards. Information from DNA as to approvals/disapprovals is extremely useful. d. Attached as an inclosure is the cumulative status of Awards submitted by the Joint Task Group since the beginning of the project until 1 May 1979. 1 Incl as {1'. \ EFFECTIVE AS OF 1 MAY 1979 0 0 JOINT SERVICE AWARD RECAP ' JOINT SERVICE COMMENDATION MEDAL I i SUBMISSIONS/APPROVALS .

FCRR CPT Cherry 19 May 1979 FACT SHEET' SUBJECT: Summary of Radiation Control Committee (RCC) Actions Since 14 February 1979 PURPOSE: To provide subject information. BACKGROUND: Federal and DoD regulations require that there be a committee such as the RCC to act as the advisory 'body to the responsible authority, in our case, CJTG. FCDNA OPLAN 600~77, in creating the RCC for the Enewetak Atoll Cleanup Project, further mandates the RCC as follows: The RCC shall advise the commander on all aspects of the radiological protection program, evaluate all real or alleged overexposures of personnel, make recommendations concerning levels of radiological protection, and evaluate all radiation protection SOPs and EAis, including revisions thereof. DISCUSSION: T'WO RCC meetings have been held since 14 February 1979. a. The 17 March meeting was concerned with the personnel protective measures which were being followed during the fission product survey. There had been discussion about relaxing the requirement for respiratory protection during the backhoe operations, but the final result was that respiratory protection would continue to be required during the digging operations. b. The 17 April meeting addressed rad.iation safety in the Cactus Crater., where soil-cement operations are underway, and on Lujor, where soil excision and movement are ongoing (these two subjects are discussed in separate Fact Sheets). Preliminary findings of the 7th RSAIT were also discussed: a short-coming (which has been corrected) of the swipe identification system, and the fact that an individual in Cactus Crater was not wearing proper respiratory protection. Finally, a criterion for detennining when a departing visitor will furnish a urine sample was recomrnended by the RCC and approved by CJTG (sample will be provided after a total of 30 days have been spent on controlled islands). 0 FCRR SFC Wendland 19 May 1979 FACT SHEET SUBJECT: Film Badge Handling PURPOSE: Provide information on past and current film badge handling. BACKGROUND: High incidence of film badge damage in the past has brought about continuing new methods of is.suing to minimize or prevent damage to badges. There has be.en from 20 to 100 percent damage during each film badge period since program went into effect during June 1977. The method used during the 20 February 1979 to 18 March 1979, perioq used a two mil (0.002 inch) sealed polyethelene inner bag with a three inch square, four mil (0.004 inch) vinyl outer bag which was double heat sealed along with a zip lock closure. During same period, one half of badges, had a small individual dessicant packet added to each inner bag with film badge and holder.· During following period 19 March 1979 to 14 April 1979, all badges were issued with individual dessicant packets. The last method is currently in use. DISCUSSION: Results from Lexington-Blue Grass Army Depot processors indicated 90 to 100 percent film badge damage for September 1978 thru January 1979 (four film badge periods). At that point it was found that possible damage was coming from moisture contamination in shipment between this Headquarters and LexingtonBlue Grass processors. As a result, J2 HQJTG started segregating badges into three groups for shipment to processor. The groups being: wet, suspected wet, and dry. Badges from each group are sealed in separate polyethelene bags with dessicant. Results for the 15 January 1979 thru 18 February 1979 period was reduced to only 49 percent damage. Qaulity control procedures during bagging improved the results for 19 February 1979 to 18 March 1979 period to only 19.7 percent damage. Through improved screening at turn-in, all wet or suspected wet badges are to be segregated for shipment to processor to prevent additional moisture contamination of undamaged badges. 0 FCRR CPT Cherry 19 May 1979 . I FACT SHEET ~ SUBJECT: Beryllium Air Sampling Program PURPOSE: To provide summary of subject program. BACKGROUND: Rocket engine tests, involving fuel containing beryllium, took place on Enjebi in 1968 and'l970. After operating nonnally for a short time, an engine exhibited uncontrolled burning which resulted in contamination of the location by chemicals containing beryllium. Decontamination efforts were performed at the time, but soil samples taken in January 1978 indicated that some beryllium remained. Some concentrations as high as 30 micrograms (µg) of beryllium per gram of soil were found, but as a general rule the most concen~ trations were much less than this. At present, there are no Federal guidelines for acceptable beryllium concentrations in soil, although industrial standards exist which allows 100 µg Be/g soil around beryllium plants. If this value is divided by ten, which is the ratios between radiological guidelines for radiation workers and those for non-radiation workers, then it is implied that 10 µg Be/g soil may be an acceptable guideline for public use. In any event, Federal guidelines do exist for beryllium concentration in air: 0.01 µg Be/m3 air, averaged over a 30-day period. The HQJTG;1 beryllium air sampling program, using aoot's air sawplers, began in early January 1979 and was completed in April 1979. DISCUSSION: Electric air sarrplers powered by an on-site generator originaliy were planned to be used. However, nu.~erous difficulties with generators forced the use of the gasoline-powered R9ot's samplers. The project ran smoothly from that time except when rain damage to filter papers required additional sampling to make up for the lost periods. In mid~March, when only a week of sampling time remained, the program ran out of the proper kind of filter paper (only half of what originally ordered had been received). The sampling program was completed· upon the arrival of the requested paper in late March. A total of almost 12,000 m3 of air were sampled at the four locations on Enjebi. Results received from the Occupational and Environmental Health Laboratory at Brooks AFB, TX, indicated concentrations of less than 0.001 pg Be/m3 air. No further action is anticipated. FCRR CPT Cherry 19 May 1979 FACT SHEET SUBJECT: Radiation Safety at the Aomon Crypt PURPOSE: To provide a summary of the radiation protection program as it has been implemented at the Aomon Crypt. BACKGROUND: The excavation of radioactive soil and debris from the Aomon Crypt began after extensive planning and coordination. Discussion of radiation protection procedures at the Crypt was a part of the planning process. While the previously established radiation protection program was adequate for a large portion of the excavation operation, certain aspects peculiar to the excavation required special attention. DISCUSSION: The Aomon hotline, which is near the Crypt, is routinely manned by not less than two FRST members. In the early part of the operation, an additional FRST member was always present at the excavation site when work was underway to insure that appropriate radiation safety procedu:r:.es were being followed and to monitor personnel, equipment, and debris for radioactive contamination, as necessary.· As work progressed and personnel became·familiar with radiological requirements, only periodic checks were performed. Saturated soil and wet debris were removed from the Crypt, so respiratory protection was not normally required during excavation. However, when the dry~r soil was being moved from the Crypt to the beach stockpile and later loaded onto boats, the established protective measures were enforced, guch as requiring the dump truck drivers and bucket loader operators to wear respiratory protection. Air sampling also followed the established EAI: one air sampler at the hotline, one at the Crypt during excavation or soil movement, and one at the beach stockpile site when soil movement occurred there. No significant airborne activity has been found. Handling of debris by personnel (wearing gloves), rather than by machine, was kept to a minimum because of the likelihood that a person could be cut and the wound become contaminated. The debris was found to be plated with plutonium and coated with an asphalt-like substance which easily flakes off. These highly contaminated flakes fell into the Crypt water and thus the Cryp_t soil was declared to be contaminated and designated for removal to Cactus Crater whether or not actual measurements of transuranic contamination had been performed by the DOE/ERSP. Finally, rubber boots were required within the Crypt area near excavated soil and debris because the wet conditions in the Crypt enhanced the chances for contamination of footgear. However, significant levels of personnel contamination were never observed. FCRR SFC Wendland 19 May 1979 FACT SHEET SUBJECT: Personnel Dosimetry Program PURPOSE: To provide information and current status of program. BACKGROUND: A film badge program was instituted in June 1977, using the standard Army film badge holder with film dosimetry, being processed by Lexington-Blue Grass Army Depot. This program was to provide data for posting onto DD Form 1141 (Record of Occupational Exposure to Ionizing Radiation). Because of film badge damage during the first six month period, ranging from BO to 100 percent, Thermoluminescent Dosimeters (TLD) were obtained for use in conjunction with film badge by personnel on northern isl.and cleanup. The TLD co-issue with film badges began on 25 May 1978. Because of continued high percent damage to film badges, additional TLD's were obtained so that as of 18 March 1979 all personnel on film badge program have both film badge and TLD. Since the beginning of the personnel dosimetry program there have been 2,436 DD Form 114l's initiated~ DISCUSSION: During early months of program, the film badge damage created problems of coming up with an administrative dose for posting to 114l's. The period 17 June 1977 thru 20 November 1977, was first calculated by the Office of the Surgeon General and then posted to 114l's. All. the administrative doses for the same period were recalculated by FCDNA using island access information. This created a requirement to remake numerous 114l's. Delays were encountered in calculating the administrative dose thru the period ending 20 May 1978 because of the lack of back up dosimetry and compiling the island access and exposure information. Administrative doses are coming more rapidly allowing proper posting of data to the individual 114l's. To date 9,670 entries have been made to 1141 '.s using film badge results and administrative dose calculations which has allowed completion of 734 DD Form 114l's. As the administrative/TLD doses are compiled and returned, this.Headquarters will be able to complete the remaining 1200 DD Form 114l's on personnel who have completed their tour at Enewetak Atoll. FCRR CPT Cherry 19 May 1979 FACT SHEET SUBJECT: Radiation Safety at Cactus Crater PURPOSE: To provide the radiation protection program implemented at Cactus Crater on Runit. BACKGROUND: The majority of.personnel inside the hotline are now employed in or near Cactus Crater. The large number of personnel involved in the soil-cement operations and the distance between the crater and the Runit hotline necessitate special considerations in the implementation of the radiation protection program. First, it was necessary to establish a break area for water close to the job'..'site. A second consideration is the variety of activities in the crater: trucks, graders, rollers, dozers, surveyors, and keywall and·molewall construction. Not all of these operations require respiratory protection at all times, so when a change of the personnel protection level was appropriate it is preferred that personnel not have to return all the way to the hotline for the change. Third, it was also appropriate that the variety of operations should be constantly observed by a FRST member, who is respons_ible for the maintenance of appropriate personnel protection levels. DISCUSSION: Established policy in the Atoll requires all personnel downwind of contaminated soil movement operations to wear respiratory protection. However, only surgical masks are otherwise usually required in the controlled area of Runit. To enable personnel to switch between surgical masks and respiratory protective masks and also allow them to take breaks for water, a "break area" serves as a special "crater hotline." Personnel can be monitored by the FRST member, who is always present, before unmasking and taking a break, exchanging masks, or drinking water. The break area is on the ocean-side of the crater where cool breezes blow in and, at the same time, is located so that the FRST member can monitor the crater for radiological violations. It is set on clean beach sand in an area where the exposure rate is less than 50 microroentgens per hour. As required by EAI and SOP, an air sampler is operated downwind of crater operations. Also, trucks are routed such that those loaded with soil enter from the downwind s.ide of the crater,· dump their loads, and exit from the upwind side. Monitoring of personnel and air sampler filter papers at the crater so far have indicated no significant levels of contamination. 0 FCRR lLT Tupin 19 May 1979 FACT SHEET SUBJECT: Radiological Decontamination and Certification of Retrograde Equipment PURPOSE: To provide information on the radiological decontamination and certification of retrograde equipment. BACKGROUND: FCDNA OPLAN 600-77 and other Federal standards require that all equipment that has been used on radiologically controlled.islands and destined to be released for unconditional use be within the limits of ANSI N328-1976 Table 1 (as amended by DOE/NV) before release. All activities which have equipment that has been on any island while the ~sland was radiologically controlled must ensure that the equipment has been monitored and decontaminated as necessary to comply with the limits of the ANSI standards. DISCUSSION: All equipment identified as having been on a radiologically controlled island will be monitored by the FRST or HQ JTG RADCON Division personnel. If all radiological data-on JTG Form 39-R satisfy the criteria stated in the ANSI standards, then the.JTG Radiation Protection Officer or his alternate may issue JTG Form 40-R, RADCON Certification of Enewetak Atoll Retrograde Equipment, which appears at Attachment 1. Monitoring will consist of direct field instrument measurements (total contamination) and the use of paper swipes (removable contamination). Prior to monitoring, equipment will be cleaned by the user by steam cleaner, high pressure soap/solvent system or other appropriate method to remove accumulate grease, oil, or other foreign matter. A copy of JTG Form 39-R, which lists decontamination limits, appears at Attachment 2. 2 Attachments as 0 I J RADCml CERTIFICl\T!OH OF ENEvmTl.~ ATOLL RETROG:1ADE E~UIP!!ENT Equipment l:1or1enclature: ~~~~~~~~~~~~- Equipment Serial number: ~~~~~~~~~~~~ Certification: I hereby certify that the described equipment may be released for uncon- trolled.use based on portable instrument readings and swipe analysis procedures and limits as set forth in Tab n to Appendix 3 to Annex Y to FCD:.1A OPU>.i.1 600-77 dated 18 December 1978 and FCrul.

BACKGROUND: In addition to.the Atoll established radiation protection program, two aspects of the situation on Lujor cause special emphasis on certain parts of the radiation protection program and require special coordination between all concerned. First, the boat ramp and soil stockpile are do\omwind of the soil excision areas. This means that the hotline must be located in the interior of the island, upwind of soil excision areas, making it difficult to observe the arrival of boats and to observe the stockpile area without moving to another position. Second, the soil on Lujor is generally more easily blmm about than that encountered elsewhere in the Atoll. The hazard due to airborne contamination extends to longer downwind distances than usual and the possibility of personnel and equipment becoming radioactively contaminated is increased. DISCUSSION: The hotline has been located upwind of the soil excision area near ·the mess and motor pool areas. To closely monitor the operations at. the stockpile and boat ramp, a FRST member remair.s in this vicinity during .the day and is able to avoid being downwind of any soil movement operations by remaining on the beach north of the boat ramp where the wind blows in from the ocean. The FRST member also controls access to the drinking water at this point so personnel can be monitored for contamination before drinking water (this also eliminates the requirement to travel all the way to the hotline for water). Coordination has been achieved with the Lojwa Naval Element so that Whalers bringing personnnel in during the day wait until operations at the boat ramp cease. The FRST member at the ramp also can control this situation. Finally, water pumps and sprinklers are being used on the soil stockpile and at soil excision sites to reduce the suspension of dust which may be radioactively contaminated. With these special efforts being made, personnel monitoring and air sampling have so far given no indication of significant radiation hazards to the workers. .o 0 FCRR CPT Cherry 19 May 1979 FACT SHEET SUBJECT: Plutonium Contaminated Rocks on Aomon PURPOSE: To discuss the pickup of plutonium contaminated rocks in the area of the Kickapoo ground zero on Aomon. BACKGROUND: Plutonium contaminated rocks at the Kickapoo ground zero were first discovered and picked up last Fall (reference Fact Sheet, FCRR, 1 Dec 78, subject as above). Estimates by ERSP personnel of the TRU activity in these rocks are on the order of picocuries to microcuries per gram of material, dep·ending on the sample. With about 150 pounds being picked up last October, it may be estimated that as much as a few rnillicuries of pl·utonium was involved. It was thought at that time the problem was solved. However, a large number of these rocks were again noticed at the Kickapoo ground zero in early May, largely as a result of Typhoon Alice on 5 January 1979. DISCUSSION: ERSP personnel now believe that these rocks may be a recurring problem. It is probable that when the. Kickapoo shot occurred, pieces of the molten tower were impregnated with plutonium and then imbedded in the reef. Now, as surf action and storms operate on the deteriorating metal fragments, the fragments are breaking loose and gradually washing ashore. It may be that this debris will continue to wash ashore for many years. DOE/ERSP is currently considering recorrunendations for solving the long term problem. As for the present, the area has again been cleaned by J2, HQJTG, and the FRST (about 200 pounds were picked up) and been placed off limits to vehicles (to preclude the crushing of the brittle fragments and spreading contamination). \ FCRE LTC Erickson 24 Hay 1979 FACT SHEET SUBJECT: Aomon Crypt PURPOSE: To provide current status of the Aomon Crypt Excavation. BACKGROUND: The Aomon Crypt was a known, marked AEC burial crypt located on the Ao.man (Sally)/Bijire (Tilda) Land bridge. Between April 1978 and Jan 1979, · the crypt was e}.1)1ored using various methods to determine the type and extent of contaminated material in the crypt. Excavation began on 15 January 1979. The estimated excavation depth (18 ft), required construction of a sheet pile.enclosure. DISCUSSION: a. Excavation presented numerous challenges. Since the isolation area enclosed by the sheet pile remained filled with water, the crane clamshell operation was very slow. Also, DOE/ERSP sampling techniques required moo7 S5/£;)07 49,587 2,CoOO 521187 4 · 21-7'7 • I TOTAL SUB/SUR i NONE. 9,200 10,003 TOTAL -101 ~0~ 3-2'1-7?

BACKGROUND: Only three islands remain for removal of debris, are Enewetak, Medren and Runit. These islands DISCUSSION: a. The large quantities. of debris on these islands and the unknown quantity to be generated during demobilization calls for innovative planning to insure timely completion of debris lagoon dumping. b. There are currently two barges (Y.C & BC) configured for debris haul with cranes on board. Two LCU's and five (5) LCM B's have been configured for bulk soil haul. After the soil haul has been completed ·a number of boats will be converted to debris haul configuration. The number to be converted is under study. c. The LARC's are available for debris removal but their production capability is limited in comparison with the other craft. d. Maintenance, especially of the loading and unloading equipment will continue to be a problem. The cranes and bucket loaders have done an outstanding job but the climate, and wear and tear are taking their toll on the equipment. e. STATUS: (1) All known red debris has been encrypted. (2) On Medren there remains approximately 18,000 cy of concrete rubble, to be moved to the northern point of the island for shore protection. Mixed with this rubble is a significant quantity of metal debris which must he removed to dump site "Alpha" in the lagoon. (3) The stockpiling of debris on Enewetak continues. The Navy Water Beach Cleanup Team has begun working on the many Master Index debris items around the island. (4) Runit debris stockpile and removal to dump site "Bravo" in the · lagoon will be executed as resources are available, (5_)_ The bulk haul boats will be available after 1 July to.haul debris. FCRE LTC Erickson 24 May 1979 -FACT SHEET SUBJECT: PACE Crater PURPOSE: To provide current status of PACE Crater backfill. BACKGROUND: a. The Pacific Area Crater Experiment (PACE) conducted by the USAF during 1971 - 1973 involved the moving of more than 110,000 cy of soil to prepare an area on Aomon (Sally) for conventional explosive cratering experiments on.bare coral surface. b. As a result of the amended stipulation of U. S. District Court, HI, Civil Case No 72-3649; HQ JTG was tasked by FCDNA in January 1978 to ~ .. assure restoration of Aomon island ••• " in accordance with the.Court directives. The only specific Court stipulation was that " •.• materials used to .fill the salt pond to the north of the test bed will remain in place.·.• 11 DISCUSSION: a. A cut/fill study by the USAE in July 1978, indicated over 100,000 cy of soil would have to be moved by bulldozer from the surrounding berms of the PACE area to the PACE Crater. Borrow areas for clean soil were Imp'ed by DOE/ERSP and work began in late July 78. b. The final grade in the crater is approximately +6 foot in reference to the mean low sea level datum and graded so that normal drainage will occur toward the lagoon. Re-Imping of the area proved that the island remains at 40 pCI/G, meeting condition "C"~ c. The PACE Crater backfill was completed on 29 March 1979 and involved the movement of over 141,000 cy of soil. Natural reseeding should occur during the current rainy season. 0 0 FCRE LTC Erickson 22 May 1979 FACT SHEET SUBJECT: Lujor (Pearl) Soil Haul PURPOSE: To provide the status of Lujor (Pearl) soil haul. BACKGROUND: c.· \i a. On 12 Feb 79, FCDNA directed HQJTG to advise on the feasibility of cleaning Lujor to 80 pCI/G (agriculture). b. HQJTG then tasked the JTG elements on 6 Mar 79 to plan for Lujor cleanup guided by the following principles: (1) Remove the minimum amount of soil to meet the criteria. (2) Transport soil to Runit in time to complete encryptment. (3) Tentative milestones: '. Lujor channel cleared Completed 18 Mar 79 Concrete ramp construction Completed 31 Mar 79 Berms and debris stockpile on beach Und~rway Re-Imping and detailed excision maps Underway· Movement of soil to Runit Underway c. Assuming a 20 cm cut, DOE-ERSP estimates excision of 23,500 cy of soil to meet 80 pCI/G. d. On 13 Mar 79 tasking received from FCDNA directed that Lujor cleanup begin ASAP and run concurrentl_y with other operations. DISCUSSION: The swift current and narrow channel made it impossible to use the LCU's for soil haul. Limited to LCM 8s, it was apparent that the quantity of soil exceeded the capability of the three (3) LCM 8s. An aggressive program to modify 3 additional LCM 8s for bulk soil was undertaken. The total soil in the windrows was re-estimated and several factors became significant: . a. Lujor soil is a fine powder and little or no fluffing takes place when the soil is removed from its in situ location. 0 d FCRE SUBJECT: Lujor (Pearl) Soil Haul b. The total soil excilsed is approximately 16,000 cy. c. STATUS: 22 May 1979 (1) A total of five (5) LCM 8s have been converted to handle bulk haul soil loads and convers:fon of a sixth is almost complete. The estimated completion date for the six!th boat is 1 June 1979. I (2) Re-Imping is P:~eceeding as quickly as the material is removed from the windrows.

FCRE LTC Erickson 24 May 1979 FACT·SHEET SUBJECT: Runit Overview PURPOSE: To provide the current status of the Runit encryptment operation. BACKGROUND: Runit (Yvonne) is the site of the contaminated soil encryptment operation. There are three distinct elements to this task: Tremie operation, soil-cement placement, and keywall/dome construction. DISCUSSION: a. Tremie operations (underwater concrete placement) i.n the Cactus Crater were completed in February 1979. b. In March 1979, HQJTG was directed to construct a 25 foot dome. Work progressed ahead of schedule for the soil-cement operation uhtil the middle of April. The continuous flow volume of contaminated soil arriving at Runit decreased due to completion of Boken and Enjebi; the Lujor access problem which limited soil movement to only LCM S's; and the need to dredge a channel to remove the Aomon Crypt soil. All channels were closed by Typhoon Alice. The U•. S. Army Element (USAE) is now estimating soil-cement completion date as 23 July, which constitutes a slip of three weeks from the original schedule. Now that transport of soil from both Aomon and Lujor is again in full swing, USAE cannot maintain front loader capability on a continuous basis to load/off load boats. With the completion of· debris removal from the Aornon Crypt, the debris donut hole (center of the dome) can be closed. c. Keyv,all construction is nearing completion. A portion of the Cactus Crater JJ.p had to be removed to ensure proper alignment IAW the Pacific Ocean Division Engineer Design. Soil from the Cactus Crater lip has been stockpiled and tested by DOE/ERSP. Preliminary results indicate that the lip material is below 40 pCI/gm. Most of those sections of the keywall removed have been placed as armor rock on the molewall. d. Although cap placement was not originally scheduled by USAE to begin until July 1st, the initial 20x20 cap section was placed on 14 Nay 1979, and five additional sections have been placed. It was estimated by the USAE that a capability existed to place four cap· sections a day. This has now been decreased to three sections per day. On 22 May 1979, CDR, USAE informed CJTG that estimates now indicate a 25 ft dome completion date of 1 November 1979. This completion could be accelerated by a dual team placement effort; however, a second power screed would he needed. FCDNA was notified in a effort to obtain the screed. Upon early arrival of the screed, a completion date of the dome is possible for 30 September-first week in October 1979 time frame. FCRE LTC Erickson 24 May 1979 FACT SHEET ! SUBJECT:. Typhoon Alice PURPOSE: iI To provide storm damage repair ·update. BACKGROUND: :On 5 January 1979, Typhoon Alice hit the Enewetak Atoll causing extensive damage to the main base camp. DISCUSSION: a.
