Backfill operations adjacent to the ERCW pipeline in the area of the A-1 spray pond.
Examination of backfill operations disclosed the following violation.
Specification N6C-875 and its referenced.,pecification G-9, specify that surfaces too smooth for proper bonding shall be scarified before placing-additional fill. Contrary to specification N6C-875 and G-9, on November 19, 1981, during backfill operations adjacent to the ERCW pipeline in the area of the A-1 spray pond, backfill was placed on the smooth surface of the previous lift without any prior scarifying.
The backfill surface had a smooth polished surface as a result of sealing the surface of the last lift of the previous day with tampers.
Failure to scarify earthfill surfaces which were too smooth for bonding was identified to the licensee as Viola-tion Item 50-518/81-20-01.
