14 Results of Records Review and Personnel Interviews
15
16 The operating records review and personnel interviews used to establish 2401-W spill history were
17 sufficiently diligent to allow PE certification of these closure activities and for use as a credible basis in
18 establishing conclusive 2401-W spill history.
19
20 Sufficient operating records and reports exist, and cognizant personnel were available for interview, to
21 establish that on authoritative and complete record of 2401-W operations exists.
22
23 Operating records and reports and personnel interviews identify no spills to 2401-W surfaces. No
24 occurrence reports were written to document releases to the-1401-W. No mention is made in'daily
25 operations logs or in weekly inspection reports of waste spills to 2401-W floors. All personnel
26 interviewed indicated that to their direct or indirect knowledge, nowaste leaks or container breaches
27 occurred that could have contaminated 2401-W surfaces. Further, stringent waste acceptance criteria for
28 containers, the relatively small quantity of waste managed at this unit, the minimal level of container
29 handling once waste was stored, and the fact that degradation of containers by weathering was not a
30 factor, greatly minimized the potential for spills.
31
32 From the records, reports, and interviews documented herein, it reasonably can be concluded that no
33 dangerous waste spills occurred to the floors of the 2401-W.
