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.

Memo introducing guidance for all EPA offices on cumulative risk assessment.
on Cumulative Risk Assessment. Part 1. Planning and Scoping
First link is to memo directing use of this guidance and second link is directly to the guidance. This guidance directs each office to take into account cumulative risk issues in scoping and planning major risk assessments and to consider a broader scope that integrates multiple sources, effects, pathways, stressors and populations for cumulative risk analyses in all cases for which relevant data are available.

- 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.
- Guidance for Data Useability in
Risk Assessment (Part B), May 1992
This document is the second part of the two-part Guidance for Data Useability in Risk Assessment. Part B provides supplemental guidance to Part A on planning and assessing radioanalytical data needs for the baseline human health risk assessment conducted as part of the remedial investigation process at sites containing radioactive substances. Part B is not a stand alone document and at all times should be used in conjunction with Part A.
