Refer to Page 9 for an example PRS Cover. The covers of some of the earlier PRS Packages may be different from this format. More than one PRS may be combined into a single PRS Package if it is appropriate from the standpoint of location, clean-up parameters, and cost . The maps and photographs show the location of the PRS in relation to the Mound Site. The History gives the general location of the PRS, identifies any processes or incidents relevant to the site being declared a PRS and identifies the site's current status.
Building are examples of incidents which have produced PRSs due to radioactive contamination.
Someone remembered a historical process or incident which may have left residual contamination in the area. The Contamination Section identifies and describes any contamination found at the PRS location. This Section also provides a comparison of existing PRS contaminant levels to the applicable guideline criteria and applicable Mound background levels. This is information needed to decide if the PRS contains contaminants which may lead to human and environmental health concerns. A brief description of sampling and analysis methods for determining PRS contamination information are in Appendix C of this manual.
