SUMMARY
OF AUDIT ,;n,y 8 in Ben CFe b b l,,t h A. A Pre-Audit Conference was held on August 31, 1977 office with those in attendance as noted in Sections II and III above. 1 The audit scope was the only item discussed. The audit scope criginally f was to observe soil placement, however, due to heavy rains and no soil ~P placement in "Q" areas, the audit scope was changed to that given in 4 y Section I. C t B.* The audit was performed on soil reports North Plant Dike MD 72 (5-23-74) .W through MD 514 (9-21-74), West Plant Dike MD 25 (9-12-74) through MD 307 [ (9-27-76), Structural Backfill MDR 611 (10-7-76) through MDR 1121 (8-11-77), Plant Area Fill MD 1122 (10-7-76) through MD 1854 (8-12-77) and gradation [ reports for structural backfill material received February 4, 1977 through ~ 1 [ August 31, 1977 to assure failing tests have been cleared by passing tests; t correct optimum moisture ' contents, maximum and minimum dry lab densities h j have been used; the test results were properly evaluated for acceptance; and test reports could be located in the Quality Control Documentation l { Vault using the attached checklist. ~L C.

-.h'C! P.! Lhi'Di N l March 7, 197b i- .CU L l To: B. Marguglio Ben - In Decccher of 1977, you requested that I look into the quality perfor=ance of the US Testing activities for the Midland project's Soils Testing Program. I incurn asked Gary Richardson to, develop information and analyses from our Quality Trend Program. The following notes reflect the analyses: 4 1. The Trend Program was reviewed in this area from 1975 to January 16, 1978 in the categories involving US Testing and Soils results. t' 2. There were a total of 176 test variances documented during the afore=entioned l period involving three categories. These were: Reports with moisture out. of j specification - 41 cases; density not as required by specification - 92 casoc; ~ ~q and gradation techniques not performed as required - 49 cases. (Some dual classifications were involved). 3. These were further broken into the following categories: 3 Method of Detection Category Number Found Per Total I ( Audit & Review No tests taken 8 out of 176 5 Audit Technique Incorrect 48 out of 176 Review Wrong Criteria 45 out of 176 Review Hissed pass or fail specification require-6 out of 176 i r.cnt Review Retests not performed 73 out of 176 4. The review method of detection to identify 134 of the 176 itets described j above was performed during a 1001" review of all of the records in turnover i packages.. A total tally was conducted and the rejection rate of the turnover [ packages indicated a 4.8% documentation variance rate. The majority of the discrepancies identified were for early work (prior to 1977). There was an a improvement in 1977. All of the findings or variances were dispositioned as 4 { use-as-is, except for one where a nonconformance report number 1004 asked for borings to validate the quality of material. 5. Corrective actions and corzents applicable to this performance: I 1. During the course of QA activity in 1977 by your and Bechtel's Quality { Assurance, US Testing assigned new supervision to the laboratory. f 2. A new man was assigned from Bechtel Quality Control in November 1977, who j reported directly to Barclay (PFQCE), to provide closer inspection i surveillance of the activity. 3. US Testing lab has instituted a double check procedure before subr.ittal of reports to Ecchtcl. This was instituted in Dececber of 1977. 4. There has been no recurrence of technique failures since the tr..ininr,prcrr.n I .i was initiated. I 5. There has been a definite improvinent in the performance.

(..i er Quality Assurance Midland, MI g207 y Job 7220 1; Described below is a series of problems and actions being taken involving J l procurement, inspection, testing and installatsion of structural backfill. 'f
- 1. 'On 1-31-77 Bechtel QA identified that all structural backfill material i
b purchased to date was purchased as " Hon-Q" which is inconsistent with } the."Q" list. This resulted in the material not being receipt inspected .y by Quality Control as is required by the " Bulk Items List" prepared by 1 i Project Engineering. (Ref. QAR SD-24) J 2. Concurrent with Iten 1 CPCo QA identified that structural backfill { delivered to the jobsite during ~12/76 and 1/77 had not in all cases b been tested for gradation on a daiTy~biiiis as required by Spec. I r 7220-C-211. (Ref. CPCo NCR QF-147) Lack of testing has been previously j identified by Bechtel QA on 10/21/76 (Ref. QADR SD-0) and by CPCo QA M g on 10/14/74. (Ref. CPCo NCR QF-29) i,'. c. 3 On 2/10/77 CPCo QA, as a result of an audit, identified that ir. many '1 I cases the gradation _ tests performed on structural backfill were I not performed using proper testing procedures. Specifically ASTfl C-135-71 states that amounts of material retained on an individual j sieves shall not exceed.200 grams. Scme tests noted had as much as 360 grams retained on an individual sieve. (Ref. audit report F-77-5 ). a 4. To assure material presently is use was acceptable Bechtel QA reviewed the test results and noted the following: 1 a. Tests run on 2/4/77, 2/7/77, 2/8/77 and 2/9/77 all had weights I retained in excess of 200 grams. l,* 4 b. Bechtel DC had not appro'ved this test and the material was still b. in the process of receipt inspection. { Bechtel Field Engineering was using this caterial without reler.sa c. by QC. NOTE: The Asst. PFQCE and PFE stopped use when notified of the discrepancy. 7 h i 00125665 l5 ....m... W
p i J. Klacking } GLR:2-7,7-32 [. Page 2 4 t i-s d. A retest of the test run on 2/4/77 resulted in a failing cradation. IlCR 700 was ganerated. fiOTE: QAR 50-25 has been issued to cover item 4c. i - Quality Control has requested U.S. Testing to review all structural 5. backfill gradation tests run to date and to identify all those that do not comply with the technique requirements of ASTM C-136-71. ,j i-6. After completion of Item 5 Quality Control will evaluate the results ~l and obtain necessary P.E. input to resolve the problem. 3 7. U.S. Testing's Project Manager will be on site 2/14/77 to investigate y l ;. ' the cause of the testing technique problem. ii In addition your atten. tion is drawn to Bechtel tiCR-578 which resulted ( i from our QADR SD-6. This I;CE has been dispositioned by Project Engineering ',i as "Use As Is" based on satisfactory test results. It is not known at this time as to the acceptability of the test techniques used for these tests. 1 Additional information will be provided as it becomes available. j. t 2 % 4 ro lV w 1 jd. CL lM G.

During review of the records in the QC Vault to verify actions taken in response to QAR 50-40 it was noted that there is no evidence of these record tests being taken. Upon further investigation it was discovered that U.S. Testing maintains a log for these tests and they are not being reviewed by Q.C. We feel that these tests should be maintained in the vault and reviewed, by Q.C. for adequacy. Please take appropriate actions to locate the moisture tests, review these tests and file them in the vault. It is requested that these actions be taken by March 1,1978 so that QAR 50-40 can be closed out. ii l1 J.:r'/2 d s G. L.

Reference:
- 1) Memo from G.L. Richardson to R.L. Castleberry dated 5/16/78 The purpose of this letter is to clarify the intent of controlling moisture content in the borrow areas as requested in Reference 1.
Sub saragraph 12.6.1 of Specification C-210 requires (" Insofar as t practicable....") qualitative control of moisture conditioning in.the borrow areas so that the soil is not "too wet" or "too dry" to be compacted with the least amount of effort after being placed on the plant fill. The only quantitative control of moisture content is specified for soil during compaction. Insufficient moisture control may lead to considerable increase in work effort and is therefore to be avoided. But moisture content is not necessarily a measure of a soil's adequacy to act as a foundation or as backfill material. If the density of a soil meets the requirements of the specification, in accordance with the correct standard, then the soil is acceptable. [ The intent of this letter is to point out that a soil with the specified i density following compaction should not be rejected on the basis that ( its moisture content was not controlled in the borrow area. On the other hand, we do not intend to eliminate moisture control in the borrow I areas because this procedure minimizes the work effort required to attain the desir m p Aant It11 de,sity. e QA f 'I* /&' :~fY.Sec.-- ( _A A7 R.

JO 733c l m-- n\\ This is a complete response to Reference 1. i It should be noted that it is ideal to control the moisture of backfill j material at the borrow areas by conditioning. It is true that moisture content tests should be conducted at the borrow areas in order to establish tha control to cost the specification requiremento. However, in che placing of soil in large quantities, it should be noted that after placement and compaction, the moistura is not necessarily the same due to drying and i mixing with oths: 1cada. This implies that a r.oisture content check is needed after tha ce=paction is acheived. Therefore, the procedure used to tcha the coistura content cents after compaction would not have direct l i=pset on the quality of work. Based on the above, we agree with field and backfill placed prior to modifi-cation of,the moisture testing methods to be accepted es is. ,4 'i q R. L.

r I called Rao, the originator of letter BEBC-1859, to clear up any misunderstanding I had on the letter. HOOK: In the past, we controlled the moisture by taking the test at the same time we took our density tests. Was this acceptable? RAO: Yes, it is, as indicated in letter,BEBC-1859. HOOK: Should we continue in the same manner as we have in the past? RAO: No. Moisture should be controlled in the borrow area prior to compaction. HOOK: Should a compaction area be rejected because it did not have the proper moisture content (+ 2". of optimum) even though the density was a'cceptable. ~ RAO: There is no moisture requirements at the time of density testing, only a density requirement. The moisture requirement is prior to compaction. I Q$ h j ROUTE 1 l[ I LQAE cm.ocJg 'cism# tAEC.M l l

0.uality Action Request - QAR No. SD-40 This memo is to bring to your attention itam 2 un6r "Recomended Corrective. Action" of the attached " Quality Action Raquest", wherein we are asked to advise Project Engineering of past moisture tasting methods In the past, it was found that densities meeting the specification requirements could be at ained, irrespective of the use of moisture T.ests, because of the uni-formity of materials. Therefore, moisture tests were taken after ccmpaction for datarmining dry densities and acceptanca or rejection was basac on c:m- .paction tasts. Moisture tests were not used to control backfill moisture. This practice has since been changed to making one moisture tast each day at the beginning of backfill operations at 500 cubic yards intarvals per spec. C-210, and one after the density of the area compacted has reached 95%. Based on the above, the Field requests that Project Engineering agree to acceptance of backfill materials installed in the past, along with records thereof, irrespective of the use of the moisture tests.

It should be noted that it to ideal to control the mois%rc of backfill materini at the borrow araas by conditioning. It is true that moistura content tests should be conducted at the borrow areas in order to establish the control to meet the specification requiremento. However, in the placing of soil in large quantitics, it should be noted that after piscament and compactics, the moisture is not necessarily tha same due to drying and mixing with other iceds. This i= plies that a moisture content check is needed after the co=paction is acheived. Therefore, the procedure used to tche the moisture content tests after co:paccion would not have direct 1 pcet on the quality of work.

for compaction." i "P.olling of any section of embankment containing material too wet or too dry to obtain the required compaction shall be delayed until the moisture content of the material is brought to within the recuired limits or the material shall be removed and replaced with suitable material..." Contrary to the above: The field does not take moisture control tests prior to and during placement of the backfill, but rather rely on the moisture results taken from the in-place sJil density tests. Recommended Corrective Action
- 1) A system for testing the soil for moisture content prior to compaction should be developed and implemented by Bechtel and the subcontractor. OC
+ should make any necessary revisions to the QCI.
- 2) Recognizing that the soil has been tested for noisture content after conpaction and meets the recuirecents o' tSe specification it is not necessary to identify these materials as nonconforming. However Troject Engineering should be apprized of the past testing methods.
In addition it is recommended that engineering concur with the interpretation that moisture contents taken after compaction are for determining-dry densities and should not be used for specified moisture control.
- 3) Assure responsible personnel are aware of the testing system.

OAR S0-40 was issued on 7/22/77 to request testing of soils for proper moisture content prior to compaction. Several IOMs and telecons were written to resolve this QAR cumulated by the attached IOM BEBC-1998 and J. Hook's telephone call record of 10/13/77 These documents indicate that rnisture content for "0" listed material must be controlled to assure that it is within +2',' of ootimum prior to compaction as required by Snecification 7220-C-2?iS. I'.oisture content after compaction not within the raauired rance is not to be considered a problem. Subsequent to this a telephone call record (attached)' dated 4/7/73, was r;ade to record a call to S. Rao requestino further clarification. Part II of this telecon appears to be in conflict with the foregoing. The current interpretation by Guslity Control is to allow compaction j to take place where the initial test indicates out of tolerance f moisture content concurrent with corrective actions to correct the i Goisture. ij Concerns in this area have been raised by D. Horn of CPCo QA who has _j requested that this area be clarified prior to resumption of work upon -j settlement of the laborers work stoppage. Jj It is requested that you take action to resolve this situation and to provide clear direction for the control of moisture content. 1 One ~possible solution would be to delete the requirement to control the moisture content and rely on the compaction requirement only for the completion of soils work realizing that the only "Q" listed work remaining is in the plant fill area.

However, this property of the soil is not necessarily a measure of its adequacy after compaction. ji The primary goal is to obtain the specified dry density. In order to achieve this end, certain means are prescribed; e.g., ma=iv.im lift thickness, specified compactive effort and controlled coisture centent. Soil which has.been tested a few days folleving compaction and found to have suitabla dry density should not be rejected solely on the basis that its coisture content is not t.-ithin 2% of optimum.

dated 8/31/77 SECy NLW6' r Wo ; This is a complete response to Reference 2. '1. Project Engineering's earlier review.of test MD354 and MD356 was based on the naasured distance as "100'R" of the centerline dike. Normal survey practice would interpret this to mean 100 feet right + of the centerline, with the surveyor'looking ahead on statio.n. Because dike stationing is counterclockwise, the earlier evaluation assuming these two tests r:, be east of the centerline is appropriate. Not withstanding the above, Consuners Power apparently believes F E 1 these tests to be west of the dika centerline (Reference 1). If f MD354 and MD356 are indeed west of the dike centerline, these tests ? would be in the plant fill area. No safety related structure or U systen will be located in this area. Therefore, the four passes of the roller can be accepted.as adequate. t We concur that reference to MD359 in Reference 3, top of the'second ~ l page, should read MD356, 1 ~[ 2. The location of MD115 is 50 feet left or west of the dike centerline p at station 5+00. Section T. Drawing C-119 and Section K. Drawing C C-117 are identical on the plant side (i.e., west side) of the 5 fill. Therefore, test MD115 is shown in a zone 2 area, based on L either Section T, Drawing C-119 or. Section K. Drawing C-117. [ l [' Apparently our earlier evaluation of test MD358, 359, and 440 was . not understood. The earlier evaluation noted that there may "...- i have been an error in identifying the location of the test MD358 and MD440." Consumers also has recognized such a possibility in j their similar questions about NCR QF 172. It is agreed that there ~ .i-S8125580 3 ~. _. -,, ,-,, n n,-,..n
e Bechtel Associates Professional Corporation q IOM to G. L. Richardson i F I Page 2 1, are discrepancies in the soils test reports, wherein the test { location and soil types listed in the reports are not always i consistent with the design drawing dike cross-sections (e.g. l zone 2 material listed as material used where zone 1 material i However, we have reviewed reports for l should have been used). ~ adjacent tests in the same vicinity of test MD358, 359, and 440; again we conclude that the sone 2 material in a zone 1 area should be considered an e-aty. (See Attachment A) 4 While it is unlikely that the dikes would be acceptable if there were conclusive evidence that zone 2 material had been widely used in lieu of the specified impervious material, the test reports in The reports from adjacent test total do not support this position. J in the vicinity of MD358, 359, and 440 do not support the theorem l that a zone 2 material is at the locations as described in the tes i l report. a Therefors,the request for a Project Engineering evalua + about errors in recorded data is not appropriate, nor do we warranted in this case. based on the same test report information which already has been ques-d tioned as anomalous by Consuners; the conclusions would only be as gooA as the facts used as the basis of the evaluation. dd that documentation errors will infrequently occur, it is not recotenen e that each document discrepancy be evaluated as though if were fact. Our office is satisfied that appropriate quality control programs, j, including Geotech surteillance, should provide adequate confidence .j in the dike construction and its acceptability. To reiterate our earlier evaluation, we recomend acceptance of 4 test reports MD359 and 440, based on the soil classification as a 'j zone 2 material, albeit in a location other than as described in i the test report. l If requested, Project Engineering is available to visit the je'esite to further discuss this evaluation with your office and Consumers J QA. 4 ,6 .

~. ;. - NCR-d84 The QCE did use the work " rework" in his statement for disposition ', results (Block 25) however, the work was done in accordance with the ' f: approved disposition of standard repair. The use of the word " rework" 14;. ; in Block 25 does not have any effect on the item or the Nonconfomance Report.' ;/;? NCR-687 The disposition was not tied to slump loss in transit alone. The s.. i. i disposTtion indicated the cylinders at the batch plant made on the same M batch (13059) would meet the specification requirements and that an ..,yr? increase in strength beAween'the Batch Plant and placement is expected to '..c. occur. This disposition ~ha's been proved out in that the 90 day strengths V. s for cylinders #1378 (which ri.present batch 13059) was 6795 PSI whic considerably higher than the required 6000 PSI. that an additional increase in strength of 900 PSI is expected between the a "?s Batch Plant and placement, the disposition of "Use-As-Is" is acceptable.

Plotting these results on the Compaction Test (Proctor Curve) shows the results fall to the right of the zero air voids curve. The importance of understanding this anomaly cannot be too strongly stated based on the past sectiement problems for which no clear cut base cause has ever been ascertained.

Dear Sherif:
I have reviewed the modified Borroc anchor settlement data through August 2, 1979, recently sent to you by SRI, in an effort to see whether measurement objectives are being met. Plotted data is sum-marized on enclosed Table 1. The contours on Figure 1 are based on data from the four anchors set at elev. 535 ft. Figure 2 is pre-o pared from Table 1. I have the following comments: 1. BA 61 through 64 data indicates that those four points on the mezzanine floor are settling in a plane (i.e. 3 points define a plane, and the fourth lies on it). Referring to the set of Si" x 11" sheets handed out durir g a meeting in early June, the contour orienta, tion defining this plane is between the orientations on tte fifth sheet (attached here as Fig. 3) and the sixth sheet (Fig. 4). Hence orienta-tion appears consistent. I 2. I've used Fig. I to determine NW and SE absolute settle-ments for the 60-120 day elapsed time period, and added these to your third sheet from the early June meeting (at-tached Fig. 5). Settlement rates appear consistent. This fact supports the contention that BA 61 through 64 data are absolute settlements, i.e. that elev. 535 ft is below the seat of settlement, because your plotted data are re-ferenced to a deep' benchmark. Sondex data will give fur-ther imput to this, as they will include a pattern of ver-tical movement throughout the foundation above elev. 535 ft. SB171085 30 TOWER RO.. NEWTON UPPER FALLS.

Fig. 2 indicates the same type of scatter noted on the optical survey Borros anchor and se'.tlement platform plots (Eleventh sheet of your June meeting handout, here as Fig. 6) and I recommend that you work with these data in cluster groups, as you did to derive the twelfth sheet (Fig. 7). Fig. 2 shows, as it should, genert.lly lesser settlement with depth and ger.erally lesser settlement towards the NW zone. It also shows continuing settlement below elev. 585 ft. I believe it is realistic to add the fo'tr BA 61 thrcugh 64 points (0.230, 0.195, 0.140, 0.005 inches) en Fig. 2 at the elevation of the j bottom of the footings (628 ft ?), i.e. to assume no signif-icant length change between footings and mezzanine floor. 4. As described in Bill Beloff's July 13, 1979 letter to you, l the plotted data are not yet corrected for temperature per se, but in general exclude afternoon readings. A study cf temperature data to date (tempereture readings and invar rod ? deformation readings) indicate that any temperature correc-tions will be minor. t 5. Would you please give some thought to the need for settle-ment readings after surcharge removal, as per page 3 of my May 31, 1979 letter to you, so that we can be sura SP.I has sufficient lead time to obtain any required materials. Please call ma if you have any questions on this. Since 'lv, 7 { )W ~ c o CJD:me J n Dunnicliff i Geot chnical Instrumentation cc: Walter R.

Midland Project Contract Gentlemen: At the request of your jobsite personnel, consider this correspondence our request for a meeting to discuss the problems that have been, and are being, encountered with attempting to place Zone 1 fill en the sub-ject project. The difference in characteristics of the fill material, frou that on which our proposal was based necessitating the changs in spacification as per Change Notice #6F, has resulted in the following: 1. Psause of the finer gradation of the material, it has men nec-esaary to exert significantly more effort in order to get the mater-ial within the specification requirement on moist'.tre, resulting in higher cost. 2. This also results in our not being able to place fill on many days because it in hnpossible to dry the material to the specification requirement prior to receiving additional rainfall, resulting in delay time on our equipment and personnel as well as schedule. We feel a meeting could be significantly beneficial from both a schedule and ' financial standpoint. Possibly something can be done to initiate j a :nore workable specification that will enable the job to progress j much more rapidly and economically. B<tcause of the facar material encountered in the borrow area, we are luoking at a significant cost differential which could result in a le.rge claim if uhe present specification has to be adhered to. If the moisture requireraant can be relaxed, we feel that the required den-sities can still bs attained with a min 4== f additional compactive effort lessening tne possible claim very a tly. It would also enable us to wo

Oversize rocks and organic material inadvertantly placed in Zones 1 & 2 by Subcontractor. j Whenever this violation was encountered, empty motor scrappe:s l were routed over the affected area for removal of these non-conforming materials from the Dike. 2. Contamination of Sand Drain caused by traffic (c;nstruction equipment) crossing over it. ] Contamination was the result of clay soils bing udxed into the j clean Zane 3 material. This situation was remedied by the re-moval of the contaminated soils from the Zone 3 areas and reusing j it in the Zone 2 areas. I l 3. Material being placed on Dikes without cor. trol during shaping of j , slopes. \\
- .i The Subcontractor was informed that whenever this situation existed, 1
the material being pushed up onto the top of the Dikes from the i slopes would be considered aa a tutorial placement and would have to be documented and controned as such (i.e.; compaction and moisture requirements). 4. Saturated soils placed oc. Dikes. When this situation existed, the Subcontractor was instructed to either remove or recondition this material before placement of r additional materials would be allowed. 5. Sandy soils being placed as zone 1 material. Any soils inadvertently placed in Zone 1 that could not be classified as impervious were removed by routing empty motor scrappers over the i affected area.

i j Dear Mr. Keeley i This letter is writtaa to provide a complete and factual response to reference 1), as " Article 9" letter regarding the use of the perennent i air piping due to the temporary air line leak in the tank farm area. l Confiratag previous discussions between Joel Newges of Bechtel and j Tom C4.oka of Consumers, we identified this leak ta the fall of 1978. We started escavating in early spring 1979 in an attempt to locate and repair the source of the leak in the air lina. 'We stopped this effort shortly af ter it started because we were in a "stop work" unde on Q-listed soils work. We felt that contimulag the escavetion (to reach the leak) would only espose a larger area to weathering during the ground thewing and spring raias period with no quick recourse for refilling because 4 50178157
I BLC-8313 Mr. C. S. Keeley October 18, 1979 Fage 2 of the stop work. It is important to nota kekision to stop was also based on the feeling that the disruption to the soil was local and, in that respect, posed no great oserall threat to the entire tank farm area. We believe that subsequent investigations have adequately substantiated that position. In stopping, we planned to resuas our investigation in early sisaner. When the NRC inspector, Mr. Callagher, visited the site the week of May 14, 1979, he showed great concern over the presence of air bubbles in the tank farm area. He, in effect, demanded that the air line be shut down. Bechtel sad Consumers Power Company worked very closely on this matter since shutting down this air line would require a ? cassation of many work activities in the audif ary building which required construction air service. It was the project's considered decision that work must continua and, also, that the temporary air line be shut down. Tau Cooka's letter (reference 3) formalized this decision. Reference 3) presented Consumers Power Company's concern over the fact that a portion of the permanent plant air system was used after the decision to shut off the leaking temporary line. Reference 4) was prepared to provide Bechtel's response to Censumers Power Company's concerns expressed in reference 3). In effect, our response in reference
- 4) acknowledges that we did not properly coordinate the use cf part of the permaner.c plant air system tith Consumers Power Company when we learned that it would take additional time beyond that originally estimated to tie in a new construction line. In making the decision to use a portion of the permanent system, Bactical was acting pure!.y in line with Consumers Power Compant's overriding doctsion, namely, work in the at.zimry building must act be secyped be.ause of a shut down of the temporary laaking line. Moreovar, verk did continue on a rerouting of te tapporary air system with the work being completed in mid-June, 197!.
Based on the facts presented above, it is Bee.htel's considered opinion that subsection B.3 of Article 9 does not apply to the contaMnation of the permanent plant air systes, anl that the lia!tation of liability in subsection A.2.c of Article 9 spplies to the damage to property by contanination as encoutered in this metter.
