Supplemental Reports to the ASER 2009

• Statistical Methods Used in the Idaho National Laboratory Annual Site Environmental Report (pdf format) - Relatively simple statistical procedures are used to analyze data collected by the Idaho National Laboratory (INL) Environmental Monitoring Program. This supplement presents the methods used to evaluate sample results for this annual report.

• Summary of Historical Environmental Monitoring (pdf format) - Environmental monitoring has been performed at the INL Site by the Department of Energy Idaho Operations Office (DOE-ID) and its predecessors, the Atomic Energy Commission and Energy Research and Development Administration, as well as by other federal agencies, various contractors and state agencies since its inception in 1949. The organization of environmental monitoring programs has remained fairly constant throughout much of the history of the INL Site. The Atomic Energy Commission’s Health Services Laboratory, later named the DOE-ID’s Radiological and Environmental Sciences Laboratory, was responsible for conducting most environmental surveillance tasks from the early 1950s to 1993 both on and off the INL Site. Contractors operating the various facilities were responsible for monitoring activities performed within the facility boundaries, including effluent monitoring.

• Meteorological Monitoring (pdf format) - The Field Research Division of the National Oceanic and Atmospheric Administration Air Resources Laboratory (NOAA ARLFRD) provides meteorological support to the Idaho National Laboratory (INL) Site. This support includes maintaining the NOAA/INL meteorological tower network (the NOAA/INL Mesonet) and running atmospheric dispersion models for emergency response applications.
