_2-SEP 17IM ENTRANCE INTERVIEW:
Following an introduction of all participants, the NRC staff indicated that the review would consist of a tour of the site, observation of testing, review of records, and an exit interview. John Jones, the RAC site manager, described the status of remedial action construction and the activities presently in progress, and indicated that he and his QC Supervisor (Bill Tate) would be available to accompany the NRC staff on the site tour.
SITE TOUR:
The RAC personnel conducted the NRC representatives and the other participants on a tour of the site. Activities observed include the following major work areas:
Placement and compaction of the geochemical flow barrier (in final stageofcompletion).
Placement and compaction of tailings (approximately 300-500 cubic yards).
Fill and compaction of excavated vicinity property near Precision Pines railroad bed.
Other aspects of the project that were observed include the following:
1.
Observed rock cover (riprap) source.
2.
Transport of tailings from processing site to disposal site.
3.
Observed location of monitoring wc11s at disposal site and processing site.
4 Observed liner in waste retention pond at disposal site.
5.
Observed relocation of Hammersley Creek at processing site.
TESTING OBSERVATION:
During the site review, staff observed quality control personnel during their performance of field sand cone testing of the vicinity property area near the Precision Pine railroad grade. The quality control 0FC :

RECORDS REVIEW:
The staff selectively reviewed testing and daily inspection records and found them to be complete and to verify performance of construction in accordance with applicable specifications. Reviews were conducted on the following records:
1.
Gradation tests.
2.
Sand cone and nuclear density tests (96 tests recorded).
3.
Proctor dynamic test (8 four-point tests were recorded and 10 one-point tests were recorded).
4.
Instrument calibration / frequency (nuclear density gauge).
5.
Survey equipment calibration / frequency (counters, meters and cone).
6.
Staff qualifications.
a RESOLUTION OF ISSUES FROM PREVIOUS SITE REVIEW:
There were no previous issues to be resolved.
EXIT INTERVIEW:
Prior to leaving the site, the NRC staff met with DOE and RAC personnel to discuss issues identified during the site review.
ISSUES:
The subgrade (natural material) located in the east-southeast area of the disposal site (embankment apron) does not meet compaction specifications. Recorded readings show only 78 to 80 percent compaction is being obtained on this material. The RAC stated that they are presently reviewing this problem and work in this area is temporarily being halted.
Monitoring wells at the site were not secured.

The RAC is presently reviewing this issue. The RAC personnel did state that there is an alternate source near the site that will meet specifications.
