The primary goal of this document is 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.
