North Slope investigation report. Revision 1.

摘要

Approximately 190 square miles of the 570-square-mile Hanford Site is north and east of the Columbia river (referred to as the North Slope). In response to safety and environmental concerns reported from Washington Department of Ecology and the public to the US Department of Energy, Richland Operations Office, the North Slope area was investigated between December 1989 and April 1990. The investigation was limited to surface observation and comprised: review of historic records, interviews with people knowledgeable of the area, aerial search, and ground search. This investigation was used to develop an inventory of sites containing potential hazards on the North Slope and to verify whether there are any imminent safety or environmental threat(s) to the public. Potential safety hazards include open citerns, pits, and military target areas. 1 fig., 1 tab.
