EDF outlines steps for EPA to strengthen its plan to assess risks to frontline communities

Maria Doa, Senior Director, Chemicals Policy

This week Environmental Defense Fund (EDF) filed comments on EPA’s plan to assess the risks to frontline communities from nearby releases of chemicals to the air and water. The EPA’s proposal is an improvement from the previous administration, which failed to follow the requirements of the Toxic Substances Control Act (TSCA) and consider air and water releases and other significant exposure pathways for residents in “fenceline” communities near manufacturing or disposal facilities.

As we made clear in our comments, however, the agency’s planned screening approach is too narrow in scope and would underestimate the real-world risks faced by many communities.

Residents of these frontline communities often face exposure from multiple sources or higher levels of exposure than the general population, or both combined. Failing to consider the full scope of these risks could hamper EPA’s ability to craft protective rules that reduce the risks those living near industrial facilities.

We outline several areas where EPA can strengthen its screening approach Read More »

Changes for the better: EPA looks out for workers in revised risk finding for HBCD

By Samantha Liskow, Lead Counsel, Health

EPA has started to fulfill its promise to take another look at many of the chemical risk findings made during the Trump Administration. First up was “HBCD,” a collection of flame retardants present in many goods, including building insulation, furniture, and electronics. In its revised risk determination for the chemical EPA proposed important changes that are needed to protect health and the environment and are required under TSCA, our main federal law on chemical safety.

We highlighted these positive steps in our comments to the agency and urged EPA to formalize these changes when it releases its final revised risk determination for HBCD and other chemicals undergoing reevaluation.

Here is a look at the changes EPA made: Read More »

EPA can incorporate cumulative impacts in its chemical assessments right now

By Maria Doa, Senior Director, Chemicals Policy, and Lariah Edwards, Ph.D., EDF-George Washington University Postdoctoral Fellow

EPA recently asked its Science Advisory Board to provide advice on how it can incorporate cumulative impact assessments into its decisions making and on research to support cumulative impact assessments. At a public meeting of the SAB on March 2, we highlighted several areas where EPA can incorporate cumulative impact assessments right now.

Cumulative impacts refer to the total burden from chemical and non-chemical stressors and their effect on health, well-being, and quality of life. EPA asked the SAB for advice in two areas: First, what research should the agency conduct to strengthen the methods used in cumulative impact assessments. Second, and somewhat more important, how can EPA start now to incorporate cumulative impact assessments into its decision-making using data that is currently available.

People living in communities are often exposed to multiple chemical and non-chemical stressors. When individuals are exposed to multiple chemicals that cause a particular type of harm, they do not experience the risks for each chemical separately from the other. Nor are these chemical burdens experienced in isolation from other non-chemical stressors a person may face, like nutritional deficiencies or psychosocial stress. Cumulative impact assessments consider the combination and impact of both types of stressors, and therefore are more reflective of real-life conditions.

EPA assessments and decision making should take into consideration this reality and move away as much as possible from the status quo of evaluating one source, one chemical, and one environmental medium. Read More »

Re-visioning TSCA: Address the cumulative impacts of chemical exposures

Richard Denison, Ph.D., is a Lead Senior Scientist.

Part 4 of a 4-part series see Part 1, Part 2, and Part 3 here

This series of blog posts is looking ahead toward opportunities to advance a more robust and holistic vision for implementing the Toxic Substances Control Act (TSCA) as reformed in 2016.

We discussed in the preceding installments of this series the importance of ensuring that combined exposures to a chemical from multiple sources and the greater exposures and susceptibilities of certain groups are accounted for.  But it is critical to also recognize that many other factors influence the impacts chemical exposures have on our health.  This final installment in our series will discuss how TSCA can and should take into account all of these factors – that is, account for cumulative impacts.

Re-visioning TSCA: Better protect those at greater risk

Richard Denison, Ph.D., is a Lead Senior Scientist.

Part 3 of a 4-part series see Part 1, Part 2, and Part 4 here

This series of blog posts is looking ahead toward opportunities to advance a more robust and holistic vision for implementing the Toxic Substances Control Act (TSCA) as reformed in 2016.

In the preceding installment in this series, we discussed TSCA’s mandate for EPA to conduct comprehensive chemical evaluations.  The Trump EPA’s failure to do so especially detrimental to those groups at greater risk because they are more likely to face the precise exposures and susceptibilities that the Trump EPA excluded.  In this installment of our series, we will address how TSCA can and must be used to better protect those at greater risk from chemical exposures.

Re-visioning TSCA: Comprehensively assess and mitigate chemicals’ risks

Richard Denison, Ph.D., is a Lead Senior Scientist.

Part 2 of a 4-part series see Part 1, Part 3, and Part 4 here

After our look back in Part 1 of this series at the damage done over the past four years, the remainder of the series will look ahead and explore opportunities to advance a more robust and holistic vision for implementing the Toxic Substances Control Act (TSCA) as reformed in 2016.

In this installment, we will discuss why legal and effective TSCA implementation demands that EPA undertake comprehensive assessments of chemical risks that supersede the media-specific limitations of other environmental laws. Read More »
