Errata Sheet for Post-Closure Inspection and Monitoring Report for Corrective Action Unit 110: Area 3 WMD U-3ax/bl Crater, Nevada Test Site, Nevada. For the Period July 2006-June 2007

摘要

The last sentence of the second paragraph of the Executive Summary on page ix incorrectly states the period for repair. Cracks or areas of settling exceeding the 15 centimeters (6 inches) deep that extend 1.0 meter (3 feet) or more on the cover will be evaluated and repaired within 60 days of detection. The second sentence of the third paragraph of the Executive Summary on page ix incorrectly states the month that cover repair was performed while omitting the discovery of additional settling, which was repaired during the originally-stated repair month. The corrected sentence (with additional sentences added for clarification) reads, 'This area of settling on the cover was repaired in October 2006. Additional cracking was observed during the October 2006 repair that exceeded the action level and was repaired in December 2006.' The last sentence of the fourth bullet of Section 2.2 on page 5 incorrectly states the period for repair. Cracks or areas of settling exceeding the compliance criterion will be evaluated and repaired within 60 days. A repair event was omitted from Section 3.4 on page 13, which should be included as Subsection 3.4.1, 'October 26-30, 2006, Repairs'. The subtext included with this subsection should read, 'During the September 19, 2006, inspection, one area of settling on the southeast portion of the cover exceeded the settling compliance criterion. The area was repaired over the period of October 26-30, 2006. A portable, gas-powered tamper was used to compact the cracks in the cover. The area was backfilled with clean, native soil using wheelbarrows and shovels, and then compacted using the tamper.'
