New guidelines to inform EPA’s approach to cumulative risk

By Paige Varner, PhD, Scientist, Healthy Communities / Published: September 12, 2023

What’s New?

The Environmental Protection Agency (EPA) recently released and solicited public comments on its draft Cumulative Risk Assessment (CRA) Guidelines for Planning and Problem Formulation. The purpose of a CRA is to determine the combined health and/or environmental risks from multiple stressors and chemicals that can cause the same harms. These guidelines, intended to be applied to all of EPA’s programs and regions, describe how the agency will determine when to use CRAs and the steps it will take to plan them.

Why It Matters

Currently, many EPA programs assess the health and environmental risks of single chemicals, without considering the multiple chemicals that cause the same harms and non-chemical stressors we are exposed to every day. Assessing risks cumulatively, and making regulatory decisions based on this, represents real-world exposures more accurately than single-chemical stressor risk assessments. Read More »

ICYMI: EDF Cumulative Risk Assessment Framework Webinar

By Maria Doa, PhD, Senior Director, Chemicals Policy / Published: September 12, 2022

On Wednesday, September 7, 2022, Sarah Vogel, EDF’s Senior Vice President for Health, welcomed over 150 attendees to a webinar on EDF’s new Cumulative Risk Assessment Framework (CRAF). The event featured presentations by:

  • Lariah Edwards, PhD, EDF post-doctoral fellow and Associate Research Scientist, Department of Environmental Health Sciences, Mailman School of Public Health, Columbia University.
  • Devon Payne-Sturges, DrPh, Associate Professor, Maryland Institute for Applied Environmental Health, School of Public Health, University of Maryland.
  • Deborah Cory-Slechta, PhD, Professor of Environmental Medicine, Pediatrics, Public Health Sciences, and Neurosciences, University of Rochester Medical Center.

EDF staff developed this new tool to provide a practical pathway for applying comprehensive, cumulative chemical risk evaluations within the framework of the Toxic Substances Control Act (TSCA).

The tool is designed to support EPA’s mandate under TSCA to provide: 1) A holistic consideration of chemical risks, and 2) Special consideration of those who may be at greater risk because they are more susceptible to a chemical’s effects or more highly exposed.

The framework begins with the evaluation of a single chemical and moves toward an approach that takes into account multiple chemical exposures, as well as other, non-chemical stressors—like racism, poverty, and lack of access to health care. In combination, these factors lead to higher risks of disease and disability from cancers and heart disease to poor birth outcomes and childhood asthma.
