' QI-057 Rev. 6 7s 1.0 PURPOSE This Quality Instruction (QI) presents the attributes and accept /

reject criteria for the performance of a documentation review for fill,and backfill placement.

2.0 APPLICABILITY This QI applies to the performance of an independent review of the documentation for the safety-significant attributes for all

, safety-related soil / rock fill and backfill placement in Unit 1, 4 Unit 2, and common areas. It applies to the samples selected from the population described in the Population Description for Fill and Backfill Placement.
