Action Information

Action Date Action Description DEC Staff
4/15/2000 Site Added to Database Ordnance or ordnance-related problems. Elim Yoon
4/15/2000 Update or Other Action The Level I Screen is a framework intended to facilitate somewhat objective evaluation of subjective issues and information. The screen considers the ordnance characteristics of the site (i.e., type of ordnance and density) along with physical characteristics of the site (i.e., terrain and vegetation) to determine the qualitative risk associated and the general category of future action that may be needed at the site to minimize that risk (i.e., additional investigation, remedial action, or no action). The screen also incorporates evaluation of the strength of evidence upon which screening decisions are made to ensure that there is reasonable supporting data for the choices made at this stage of the process.
