Habitat preferences and distribution of the brown rat (Rattus norvegicus Berk.) in the city of Salzburg (Austria): implications for an urban rat management Abstract The population of Rattus norvegicus was assessed using live traps and hair sampling tubes in 71 discrete patches distributed in the urban area of the city of Salzburg, Austria. R. norvegicus occurred in 35% of the examined habitats and reached a maximum density of 113.12 individuals/km along water banks. The occurrence of rats was strongly influenced by vegetation, habitat modification and man-made impact in the area. The results of this study could be used to support the development of a new, more scientifically based rat management plan in cooperation with the city of Salzburg.

The CPP-603 (annex) Chloride Removal System (CRS) Decontamination and Decommissioning (D&D) Project is described in this report. The CRS was used for removing Chloride ions and other contaminants that were suspended in the waters of the underwater fuel storage basins in the CPP-603 Fuel Receiving and Storage Facility (FRSF) from 1975 to 1981.The Environmental Checklist and related documents, facility characterization, decision analysis 1, and D&D plans 2 were prepared in 1991. Physical D&D activities were begun in mid summer of 1992 and were completed by the end of November 1992. Ali process equipment and electrical equipment were removed from the annex following accepted asbestos and radiological contamination removal practices. The D&D activities were performed in a manner such that no radiological health or safety hazard to the public or to personnel at the Idaho National Engineering Laboratory (INEL) occurred.
