Additional RCRA Information:
This is the stage in the Ecological Risk Assessment process where it is determined what the extent of the problem is likely to be. The scope of US EPA risk assessments describes what is currently known about the environmental risk at a particular site that will (or can) be analyzed. The scope is defined according to who or what is at risk of adverse effects from identifiable sources and stressors through several routes of exposure over varied time frames.

- Guidance for Data Useability in
Risk Assessment (Part A) April 1992
Guidance for Data Useability in Risk Assessment, Part A, is designed to provide data users with a nationally consistent basis for making decisions about the minimum quality and quantity of environmental analytical data that are sufficient to support Superfund risk assessment decisions, regardless of which parties conduct the investigation. Part B of this guidance addresses radioanalytical issues.
