Mr Gallagher vendered hov ve could have been placing soils since last su==er if a qualification repcrt had net been revieved and apprcved by quality. he stated it vould be a very sericus sitw. tion if the analysis of the report shesed there was equip =ent dee=ed to be not qualified which had been used for scil.,

Den Horn stated that his review to date has resulted in :ene questiens on qualificatiens for place =ent of clay but that se Q place = ente have *i:een =ade with this equipnent. The qualification of the equip =ent for place =ent cf sands appear to be sub:tantiated. To cur kncviedge, no Q place:ents had been =ede prior to Bechtel Pro,)ect Engineering's release of the equipment in writing to the fieJd.

l'e stated that the qualificatice repcrt was planned to be sub=itted in a June

s Was/lr Editerial Note - Neither our 50.5h(f) response ner the Bechtel P o.ra= require =ents require a Quality Assurance line involvement in the Engineering activities to certify the qualification of the cc=pection equips.ent. FIC 1.100 places the qualification and records for qualification of co=paction equip =ent with Geotech.

Dear Mr. Keeley:
This letter is written to provide a complete and factual response to reference 1), an " Article 9" letter regarding the use of the permanent air piping due to the temporary air line leak in the tank farm area.
Confirming previous discussions between Joel Newgen of Bechtel and Tom Cooke of Consumers, we identified this leak in the fall of 1978 started excavating in early spring 1979 in an attempt to locate and repair We the source of the leak in the air line.
We stopped this effort shortly af ter it started because we were in a "stop work" wde on Q-listed soils work.
We felt that continuing the excavation (to r6ech the leak) would only expose a larger area to weathering during the ground thawing and spring rains period with no quick recourse for refilling because 1
l 5R178157 JAN 141981 l
BLC-8313 Mr. C. S. Kotley October 18, 1979 Page 2 of the stop work. It is important to note t a beisiontostop was also based on the feeling that the disruption to the soil was local and, in that respect, posed no great overall threat to the entire tank firm area. We believe that subsequent investigations have adequately substantiated that position. In stopping, we planned to resume ou investigation in early summer.
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 and Consumers Power Company worked very closely on this matter since shutting down this air line would require a cessation of many work activities in the auxiliary building which required construction air service. It was the project's considered A
decision that work must continue and, also, that the temporary air line be shut down. Tom Cooke'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 Consumers Power Company's concerns expressed in reference 3).
In effect, our response in reference
- 4) acknowledges that we did not properly coordinate the use of part of the permanent plant air system with 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, Bechtel was acting purely in line with Consumers Power Company's overriding decision, namely, work in the auxiliary buildhg must not be stopped because of a shut down of the temporary leaking line. Moreover, work did continue on a rerouting of the temporary air system with the work being completed in mid-June, 1979.
Based on the facts presented above, it is Bechtel's considered opinion l
that subsection B.3 of Article 9 dots not apply to the contamination of the permanent plant air system, and that the limitation of liability in subsection A.2.c of Article 9 epplies to the damage to property by contamination as encoutered in this matter.

Tables 1 6 2 attached (taken from Dames & Moore's soils report of i
June 28,1968, Page 15 and its supplement of March 15, 1969, Page 16) present coupaction reconnendations for fill and backfill.
In the June 28, 1968 report, the minimum clay compaction is recommended to
\\
be 95% for support of c,rihic'jf structures, 90% for support of non-
~
critical structures, and 90% adjacent to structures, respectively; all percent compaction values are according to ASTM D 1557 Method D (abou t 56,000 ft-lb cenpaction energy).
In the March 15, 1969 report, the minitum clay compaction is recommended to be 100% for support of structures, 95% adjacent to structures, and 90% for area fill (not supporting or adjacent to structures); all percent compaction values are according to Bechtel Modified Co=paction (BMC:
co=paction energy).
20,000 ft-lb Specification 7220-C-210 (Section 13.7) requires 95% of ASTM D 1557 Method D for in-situ clay in the plant area and bern.
In comparing the reports w'ith the specification for in-situ clay supporting structures, it is seen that 1968 Dames & Moore report are identical.the specification and the Also, the specification and the 1969 report are consistent since 95% of ASU! D 1557 Method D is approximately equivalent to 100% EMC in some soils.

Ccopressibility tests may also be required.
The berm fill must be conpacted to 95% of ASTM D 1557 Method D to insure adequate scepage protection and stability.
Category I fill placed within the failure zone of a slip circle may require a degree of compaction higher than 95% of BMC, because of design for the full SSE.
However, it is conceivable that in place fill compacted to 95% of the EMC will be adequate if strength and permeability properties are shown to be adequate Similarly, in-place fill supporting light structures may be adequate at 95% of BMC provided its strength and compressiblity are shown to be adequate.
Fill in the plant area which will not support structures or pipes or be placed within the failure zone of Category I slopes may be compacted to a lesser degree than 95% of ASTM D 1557 Method D (e.g. 95% of BMC).
This agrees with Dames & Moore's 1969 report and is consistent with their 1968 report which requires only 90% of ASTM D 1557 Method D.
In-Situ Sands The Dames & Moore June 1968 report presents recommendations for cocpacting sand in terms of maximum density while their March 1969 report presents recommendations in terms of. relative density.

9 ACTION PLAN 1.
Define problem areas better by boring logs and TOPO's (PMO - work on this).
2.
Define problems by elevations (use boring logs) (PMO - OA later).
3.
Define difference between C-211 and C-210 (QA).
4.
Define what work was done by Bechtel and Canonie (PMO).
5.
Define where trenches were made (excavations) (photos, TOPO's, etc) (PMO - QA).
6.
List all equipment used by a) Bechtel b) Canonie (photos, rental sheets).
7.
Look at changes in personnel / qualifications (QA, PMO).
8.
Look at assignments of supervision to earthwork by period.
9.
Look at celecons/FCR's to spec, DR's (QA).
10.
Look at specs and also photos.
11.
Look at rate fill in areas where there was problems (PMO).
12.
Check problem areas with completion of the year's work (freeze - thaw) do with 4.
13.
Look at number of QC people assigned to soils, their time involved with soils (IR's, FE Reports).
14.
Ramps - Check photos, TOPO's, compare with borings (also gravelly areas in borings)
(can do in conjunction with 12, 4) (QA, PMO).
15.
Review weather date for periods of problems (PMO).

This is a witness point.
Contrery to this requirc=ent 5C-1.05-180 was signed off for activity 2.2a9 on 6/9/80.- 6/13/80 as NA scoped for 6/9/80 thrountL 6/_13,/.80.and _ test 6182 taken 6/3/80 and test 6184 taken 6/5/80 had 108.1 and 106.6 percent relative density recpectivaly.

8.
This itees was incorporated in the QCI at client' 04 insistence, bened on a 50.54(f) re.g e consultment to this effect.
C.
The QCI' requirement was overruled.by the GeoTech personnel instructing U. S. Testing personnel that retests will not.be i
required.
This review'was conducted on all teste subsequent to the Rev. 8 of QCI SC-105 from the period of December 3,197%
i Enrougn tne tidiffe';T~perica.
n D.
The GeoTech engineer is reputed to have given his direction to
j U. S. Dtesting under the authority of Paragraph S.3.5 of Spec.
C-211, which maya that all soils work shall be performed under
]
the direction of a qualified soils engineer.,.
i 6
RECONMENDED SOLUTION The recommended solution for this itein is for QC to implement t.he existing l,
quality program.
That is, when a test-is recorded with greater than i.
105% of the theoretical, a retest. will' be perforrmed.
QC will not accept or approve the U. 5. Testing Report that identifies a test or 105 or j
greater.
I a
CAR will be issued for corrective action.
NCR 3041 has been issued to
}
document areas where retests'ivere not performed.
s i
ADDITIDMAL ACTION r
Since this requirement is not a spec. requirement, a retest that results in 105 or greater would allow acceptance of the area without further test.

INVESTIGATION A.
QC recognizes that a number of QCIR's have not been reviewed by Q*
a Level II.
8.
The daily QC soil placement reports are reviewed and signed off by a Level II.
The daily soil test reports include the detail calculations and data of the tests and ard supplemental to the IR.
C.
Paragraph 8.9' of PSP G-6 indicates that ttw QC Engineer confirms his acceptance of the activities described in the QCI by initialing and dating the apprcpriata algn-o'fr blocks in the inspection record.
Paragraph 8.10 of the same PSP indicates that completeness and acceptance of the recorded data la =mlished by a Level II in the same discipline.
D.
There is apparently no requirement written for a timely review of the data by a Level II.
In addition to tha' daily soil placement reports being reviewed by the Level II Civil DC Engineer, the U. 5. Testing Field Density Report Test weeulta are also reviewed and signed off by the corresponding subcdntrach QC Engineer, Cavel II.
SUMARY The apparent lack of timeliness of a Level II r'eview of this data does not appear to constitute a quality problem in the acceptability of the soils work, but indicates a lack of availatle manpower in the Quality l Control organization for clearing up quality cuntrol inspection records.

INVESTIGATION A review of the Field Engineera Report Form, and the. Daily Soil Placement Report for the days in question shows e' videnes that the reports are correct.,
cm written.
The apparent dis'crepency is caused when soil is placed in an crea, but no tests are taken.
This is possible b'eb use tests are not required for each piecement lift, but rather the frequency of tests. is determined by the number of cubic yards of materi al placed, and/or at the' discretion of the GeoTech on-site engineer additional tests above the required frequency may be taken.

Specification C-211 Rev.10 section 8.6 states:
"S.6 COMPACTION EFTORT The onsite geotechnical soils engineer shall. verify.that the equipment used for compacting the backfill material is capable of obtaining the desired results and obtaining the same ace'eptable compaction effort achieved in the test pad area.
This verification shall include, but not limited to, the following:.:.a.

4 t-Contrary to this requirement, there is no Evidence in the Field Engineer Reports that this compaction effort has been verified.
(The onsite geotechnical soils engineer does not h' ave a copy of the.." Test Till Program."-)
l INVESTICATION Item No.11 related to the fact that per paragraph 8.6 of Specification C-211, the on-site GeoTech soils engineer shall verify that equipment used for corrpacting the backfill it capable of obtaining the desired results 'and obtaining the same acceptance compaction ef. fort.achi'eved in.the test pad area.
i-The auditors finding states that contrary. to this requirement, there is no evidence int he field engineer records that compaction effort has been verified.
The on-site GeoTech soils engineer does not have a copy of the test fill program.
Results of Investigation (based on conversations with Jim Wenzak and Rao) follows.
RESULTS OF INVESTICATION A.* Wonzak and Rao expressed thei.r opinion that the intent of this section df the specification was not to provide document ed ' vidence that this verifi-e cation. had been accomolished, but rather that the on-site GeoTech engineer was familiar with the soils compaction equipment capabilities and verified that they were properly used.
The precise wording in the specification is nct being adhered to.

Response to NRC Question 23, Part (3),
Section 5, Action Item 22 The referenced action ites requires that project engin'eering and geotechnical services develop guidelines for surveillance of testing
=
E operations by the onsite geotechnical soils engineer.
It is reonested that field engineering incorporate the following guidelines into.the appropriate field instruction and forward'a copy of the revised field. instruction to project engineering by February 22, 1980.
Guidelines for Surveillance of Testing Operations:
The onsite geotechnical soils engineer shall observe the testing-operations at least once a day while testing is in progress.
The testing operations to be observed shall include field density and moisture tests, laboratory prector tests, gradation tests, plotting of zero airvoid curves, etc..
Tests to be. observed vill be selected by the onsite geotechnical soils engineer.
The selection will be randon,. based on tsses being conducted on a particular day and' varied to his satisfaction such that all phases of testing are being conducted corree:17 and are providing the necessary control of the earthwork-operations.
The onsite geotechnical soils engineer shall inform appropriate authorities if the operations are carried'out incorrectly and/or if there are any other nethods or tests that could be utilized to l
l improve the control or provide increased assurance that testing operations are carried on correctly and effectively.

Reference:
BEBC-3633, dated January 30, 1980 The referenced memorandum was received by Field Engineering, on February 5, 1980.
This memo includes the following directions:
=r 5~
"The onsite GeoTechnical soils engineer shall observe the -testing operations at least once a day while testing is in progress.
The test-ing operations to be observed shall include field density and noisture tests, laboratory proctor tests, gradation tests, plotting of
=ero airvoid curves, etc.
Tests to be observed will be selected by the onsite GeoTechnical soils engineer.
The selection will be random, based on tests being conducted on a particular day and varied to his satisfaction such that all phases of testing are being conducted correctly..."
Based upon discussion among field personnel and telephone conversations with Proj ect Engineering, the field interprets this to mean that not all backfill related tests conducted each day must be observed but that at least one of the tect l
procedures on any day of testing must be observed.
We also interpret this direction to mean that all test pro-cedures related to backfill operation.s must be observed often enough so that the onsite GeoTechnical soils engineer can be satisfied as to the correctness and efficiency of testing operations and.can document such observation.
