Abstract In FY96 and FY97, preliminary assessments were conducted of the potential risk from legacy waste to the American peregrine falcon (Fulco peregrimrs), the bald eagle (Haliaeetus kucocephalus), and the Mexican spotted owl (Strix clccidentalis lucida). Estimated doses were compared against toxicity reference values (TRVs) to generate hazard indices that included a measure of cumulative effects from multiple contaminants (radionuclides, metals, and organic chemicals). The tools used included a custom FORTRAN code ECORSK, and a geographic information system. The assessments originally included only the soil ingestion contaminant pathway. Since the initial assessments, a food consumption contaminant pathway has been added, bioaccumulation and biomagnification of some contaminants have been factored into the food consumption pathway, and some of the TRVs against which estimated doses are compared have been changed to values which relate more closely to the Aves taxonomical class. With these and other more subtle improvements in model input parameters, ECORSK has been revised and the model has been re-executed for the owl and peregrine exposure units that originally generated the highest risk indices. This report contains the updated results. On average, results indicate a small potential for impact to the peregrine falcon, but no appreciable impact to the spotted owl nor the bald eagle. The original reports cited in this document should be consulted for details on methods.

“…Occupancy has been confirmed for only two federally listed species: the bald eagle and Mexican spotted owl (LANL 1999, 062887). Results of preliminary risk assessments for the Mexican spotted owl, bald eagle, and southwestern willow flycatcher are available in Gallegos et al (1997, 057915); Gonzales et al (1997, 062879); Gonzales (1998, 062349); Gonzales (1998, 062350); and Gonzales et al (2004, 085207).

This document provides guidance for screening-level assessments of potential adverse impacts to ecological resources from release of environmental contaminants at the Los Alamos National Laboratory (LANL or the Laboratory). The methods presented are based on two objectives, namely: to provide a basis for reaching consensus with regulators, managers, and other interested parties on how to conduct screening-level ecological risk investigations at the Laboratory; and to provide guidance for ecological risk assessors under the Environmental Programs (EP) Directorate. This guidance promotes consistency, rigor, and defensibility in ecological screening investigations and in reporting those investigation results. The purpose of the screening assessment is to provide information to the risk managers so informed riskmanagement decisions can be made. This document provides examples of recommendations and possible risk-management strategies. This document describes the Laboratory-wide information needed for the screening-level ecological risk problem formulation, including the environmental setting, contaminant fate and transport, exposure pathways, and food webs. Screening assessments are performed on solid waste management units (SWMUs) 1 or areas of concern (AOCs); the area may also be a collection of SWMUs and/or AOCs in a watershed or some other aggregate. In this document, the term site is used broadly to include these different possibilities.

Federal laboratories are often caught between the need to meet mission objectives and the mandate to act as national stewards for natural resources. Following the initiation of the Manhattan Project in 1943, restricted land use at Los Alamos National Laboratory (LANL) retained many undisturbed areas that function as ecosystem sanctuaries for plants and animals throughout the 43 mi2 site. We developed a Quantitative Habitat Analysis (QHA) that enables both managers and scientists to better meet the goals of ecosystem management and sustainable development for LANL. QHA is a multi-faceted modeling, planning, and management tool with the goal of applying existing models in a new way. QHA provides an objective, standardized, and replicable system for management of wild areas by federal agencies. As part of the development of QHA, we reviewed 42 existing wildlife and habitat models, assessments, or evaluation methods and 12 computer programs. A pilot field study was conducted on 12 plots testing five different methods to determine the most suitable for data collection for the tool. Once methods were selected and models determined, a QHA application tool was created in ArcView to test the pilot data within the tool for user-friendly application. This year, 45 field sites were sampled. QHA currently comprises five main sub-models analyzed within a geographic information system using ArcView: 1) Ecological Land Classification (landscape level effects), 2) Rapid Ecological Assessment (general assessment)/U.S. National Vegetation Classification Element Occurrence (ecosystem “health”), 3) BEHAVE (wildfire and fuels monitoring), 4) Habitat Analysis and Modeling System (wildlife), and 5) ECORSK.6 (bio-contaminants). Key to this QHA tool was the use of “common currencies.” The common currencies consist of weighted scores that calculate a “grade” or means of comparison between different programs and scoring methods. Development and calibration of the QHA continues.
