Risk assessments can be more efficiently completed if planning and scoping of the information and data needed to complete the assessment is considered before the field investigations and site characterization work are completed. Although this is sometimes an iterative process (with some collected data revealing the need for more information), planning and scoping before data collection generally reduce both time and cost for the site. Documents and links related to planning and scoping are presented on this webpage.

Documents

  1. Role of the Baseline Risk Assessment in Superfund Remedy Selection April 22, 1991
    This memo describes the process and purpose of the baseline risk assessment (the latter steps) in terms of remedy selection.
  2. (Revised) Policy on Performance of Risk Assessments During RI/FSs Conducted by PRPs (PDF) (3 pp, 43K,  About PDF)
    As part of the recently announced administrative reforms to the Superfund program, the Administrator stated that EPA would reaffirm its commitment to "allow PRP's to conduct risk assessments under proper circumstances as part of the overall site study (RI/FS)." This memorandum announces EPA's revised policy on allowing PRP's to conduct the risk assessment portion of the RI/FS.
  3. Presenters' Manual for: Superfund Risk and Assessment and How You Can Help (PDF) (77 pp, 1 mb,  About PDF) EPA developed the 40-minute videotape "Superfund Risk Assessment and How You Can Help" to help explain in plain terms the Superfund human health risk assessment process and how communities can be involved.
  4. Risk Assessment Guidance for Superfund, Volume I - Human Health Evaluation Manual
    Part A: Baseline Risk Assessment (1989)
    Supplement to Part A: Community Involvement in Superfund Risk Assessments (1999)
    The purpose of this guidance document is to provide the site team--risk assessor, remedial project manager (RPM), and community involvement coordinator--with information to improve community involvement in the Superfund risk assessment process
    Part B: Development of Risk-based Preliminary Remediation Goals (1991)
    Part C: Risk Evaluation of Remedial Alternatives (1991)
    Part D: Standardized Planning, Reporting and Review of Superfund Risk Assessments (2001)

  6. Soil Screening Guidance July 1996, December 2002
    The Soil Screening Guidance (SSG) presents a framework for developing risk-based, soil screening levels (SSLs) for protection of human health.
  7. Vapor Intrusion Guidance
    OSWER Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (Subsurface Vapor Intrusion Guidance). Provides current technical and policy recommendations on determining if the vapor intrusion pathway poses an unacceptable risk to human health at cleanup sites.
  8. Analytical Methods
    The following EPA Forum on Environmental Measurements link provides information on the collection and analysis of environmental samples.
  9. Data Quality Objectives
    Sampling and analysis activities undertaken during the RI should provide adequate data to evaluate all appropriate exposure pathways. Therefore, risk assessors should be involved in the development of the data quality objectives for sampling and analysis and in selecting the types of sampling and analyses that will be done. The DQOs should address the qualitative and quantitative nature of the sampling data in terms of relative quality and intent for use, to ensure that the data collected will be appropriate for the intended objectives. DQOs are discussed under Section 2.2 of RAGS Part D (PDF) (4 pp, 21K,  About PDF).
  10. Data Useability in Risk Assessment
    Data quality is an important component of the risk assessment and the evaluation of data quality should be documented. RAGS Part D includes Data Useability Worksheets (ZIP 7KB) to address this need. In addition, Section 3.1.1 of Risk Assessment Guidance for Superfund (RAGS) Part D (PDF) (30pp, 59KB,  About PDF) discusses standard tables, worksheets, and supporting information.
