Ecological risk assessment is a process for evaluating the likelihood that adverse ecological effects may occur or are occurring as a result of exposure to one or more stressors. A critical early step in conducting an ecological risk assessment is deciding which aspects of the environment will be selected for evaluation. This step is often challenging because of the remarkable diversity of species, ecological communities, and ecological functions from which to choose and because of statutory ambiguity regarding what is to be protected.
The purpose of this document is to build on existing EPA guidance and experience to assist those who are involved in ecological risk assessments in carrying out this step, which in the parlance of ecological risk assessment is termed “selecting assessment endpoints.” The document describes a set of endpoints, known as generic ecological assessment endpoints (GEAEs), that can be considered and adapted for specific ecological risk assessments. The document is intended to enhance the application of ecological risk assessment at EPA, thereby improving the scientific basis for ecological risk management decisions. However, the document is not a regulation, nor is it intended to substitute for federal regulations. It describes general principles and is not prescriptive. Rather, it is intended to be a useful starting point that is flexible enough to be applied to many different types of ecological risk assessments. Risk assessors and risk managers at EPA are the primary audience; the document also may be useful to others outside the Agency.Start Signature
