Abstract: The Idaho National Engineering and Environmental Laboratory (INEEL) is a Department of Energy (DOE) facility. To assess the impact of the site activities and releases on ecological receptors, the INEEL implemented a phased approach for conducting ecological risk assessments (ERAS). This approach applies an iterative, 'tiered' process, in which conservative preliminary assessments support progressively more refined assessments. The first phase is the screening-level ERA, which is a 'preassessment' performed at the Waste Area Group (WAG) level. This paper will address innovative methods, at the screening level, used to address systematically the complexity of the INEEL site, including adaptations of existing ERA methodologies to accommodate the functional grouping approach.
