EDF statement: Trump EPA’s withdrawal of proposed bans on dangerous uses of three chemicals is shameful

By / Published: January 14, 2021

Decision epitomizes administration’s disdain for public health protection

(Washington, DC – January 14, 2021) Tomorrow, the Trump EPA will announce the formal withdrawal of proposed bans on high-risk uses of the dangerous chemicals methylene chloride, trichloroethylene, and N-methylpyrrolidone. By taking this action, the Trump EPA seeks to prevent the new administration from finalizing any of these bans without starting the process over.

“It appears that blocking these bans and denying crucial protections to workers and consumers for four years was not enough for the Trump EPA. This shameful move that epitomizes the Trump EPA’s concerted attacks on public health is a transparent attempt to further constrain the incoming administration. It is yet another stain on Mr. Wheeler’s dismal record,” said Dr. Richard Denison, Lead Senior Scientist, EDF Health. “We are counting down the days until the EPA’s decisions, once again, reflect its mission to protect health and the environment.”

EPA’s final risk evaluation of trichloroethylene is scientifically flawed and understates risks to workers, the general public and those most susceptible

By / Published: November 23, 2020

Today the Trump Environmental Protection Agency (EPA) issued its final risk evaluation for trichloroethylene (TCE).  It largely tracks the agency’s draft document, retaining numerous flaws that severely understate the highly toxic chemical’s risks to workers, the general public and those most susceptible to its health impacts.

Among the evaluation’s most serious deficiencies is the abandonment of a bedrock principle of chemical risk assessment: that risk estimates be based on the most sensitive health effect.  Sadly, the final document retains the unprotective approach the Trump White House forced EPA to adopt, as reported in detail by Elizabeth Shogren of Reveal News.

Exposure to TCE is ubiquitous, coming from ambient and indoor air, vapor intrusion from contaminated sites, groundwater and drinking water wells, and food – yet EPA’s evaluation ignores or downplays each of these exposure sources and pathways.

Below we summarize some of the major concerns in EPA’s evaluation that we addressed in detail in our comments.

One silver lining:  Despite its glaring deficiencies, the risk evaluation did find that the great majority of TCE’s conditions of use present unreasonable risks—even as it grossly understated the extent of those risks.  As a result, EPA must now proceed to regulate those activities, providing the new Administration an opportunity to rectify the serious problems created by the Trump EPA.  Read More »

EPA refuses to extend TCE comment deadline, ignoring requests from Congress, health groups

By / Published: April 28, 2020

Joanna Slaney, Legislative Director and Lindsay McCormick, Program Manager. 

Yesterday, in the midst of the COVID-19 national emergency, the Environmental Protection Agency (EPA) closed the comment period on an extremely flawed draft risk evaluation on the toxic chemical, trichloroethylene (TCE).

Due to the many scientific and legal concerns raised by the draft risk evaluation, and its significance for any future regulation of TCE, the draft needs thorough and careful review from experts, the public, and other affected stakeholders. However, EPA refused to delay the deadline for the draft risk evaluation’s comment period, despite the growing hardships and major disruptions resulting from the current COVID-19 crisis.  EPA now seems intent on racing to the finish line with its flawed evaluation, ignoring multiple requests to ensure the document is fully vetted:

  • Congress: In two separate letters from the House and Senate, Members of Congress raised concerns with EPA moving forward with various rulemakings and scientific reviews without sufficient opportunity for expert and public input in light of the pandemic – explicitly referencing the TCE draft risk evaluation as a prime example.
  • Health groups: Health organizations whose staff and members are on the front lines of the pandemic requested that EPA extend the public comment period until after the national emergency is lifted due to severe capacity constraints. EPA did not respond.
  • Impacted communities: In early March, nearly 300 people from communities grappling with TCE contamination asked EPA to hold a public meeting to allow them “to ask questions of the agency and engage in critical dialogue.” EPA denied the request.

Former chemical industry official Beck, now at Trump White House, again interferes to weaken EPA action on dangerous chemicals: This time it’s PFAS

By / Published: April 20, 2020

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

It was only in February that Reveal News’ Elizabeth Shogren exposed the Trump White House’s role in dramatically weakening the Environmental Protection Agency’s (EPA) draft risk evaluation for the solvent trichloroethylene (TCE), which is linked to fetal heart defects at low doses.  The White House’s 11th-hour intervention, led by former chemical industry official Dr. Nancy Beck, forced EPA to rely on a different health effect that would allow 500 times greater exposures to the ubiquitous toxic chemical.

There was every reason to expect this episode was not a one-off, given Beck’s other actions both while at EPA and once arriving at the White House.  Sure enough, last week Ellen Knickmeyer of the Associated Press exposed another such incident, this time involving a group of chemicals collectively known as “perfluoroalkyl and polyfluoroalkyl substances” or PFAS that are showing up as environmental contaminants all over the country.

Beck’s first order of business was to compel her former colleagues at EPA to submit the proposed PFAS rule for White House review, which neither the Obama administration nor the Trump administration up to that point had deemed necessary.

Knickmeyer reported on documents obtained by Senator Tom Carper of Delaware, ranking member of the Senate’s Environment and Public Works Committee, that detail Beck’s largely successful effort to scale back a rule EPA first proposed in 2015.  Called a Significant New Use Rule, or SNUR, it would require companies seeking to import products containing certain PFAS to notify EPA in advance, thereby allowing EPA to determine whether to allow the import and impose needed restrictions.  Sen. Carper made the documents public via a letter he sent to EPA Administrator Andrew Wheeler calling on EPA to finalize the original rule instead of the watered-down re-proposed rule EPA released for public comment in February.  Read More »

Peer reviewers of EPA’s TCE report must affirm that the key risk is fetal heart damage

By / Published: April 1, 2020

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

Last week, the EPA Science Advisory Committee on Chemicals (SACC) conducted a virtual peer review meeting for the Agency’s draft risk evaluation of trichloroethylene (TCE). As expected, there was substantial discussion on the appropriateness of EPA’s decision to make risk determinations based on immune endpoints rather than fetal cardiac malformations (FCMs). Unfortunately, the review panel lacked anyone with specific expertise in cardiac development.

During the meeting, many of the peer review panelists signaled an initial inclination toward supporting EPA’s decision to use immune endpoints for risk determinations. However, panel members also noted with serious concern the recent investigations that have uncovered political influence exerted on EPA that led it to base the risk determinations in the draft risk evaluation on immune endpoints instead of FCMs.

Stepping back from the specifics of the discussions last week, it is important to understand the longstanding basis and support for EPA’s reliance on FCMs, the unprecedented nature of EPA’s decision to now move away from it, and the adverse implications of the decision for EPA’s ability to adequately manage the risks of TCE to all relevant subpopulations.

This decision is a major departure from thoroughly peer-reviewed science, fails to protect the most sensitive populations as mandated by TSCA, and deviates dramatically from existing Agency guidance. These concerns, discussed at length in EDF’s comments in the TCE Docket, are briefly summarized below:  Read More »

EPA’s draft risk evaluation of trichloroethylene contains major scientific flaws that understate the chemical’s risk and demand robust review

By / Published: March 19, 2020

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

Yesterday Environmental Defense Fund (EDF) filed comments on the Environmental Protection Agency’s draft risk evaluation for the highly toxic chemical trichloroethylene, or TCE.

This draft, readers will recall, is the document that the Trump White House forced EPA to dramatically weaken just prior to public release, as reported in detail by Elizabeth Shogren of Reveal News.

It is also the document that EPA seems intent on subjecting to a rushed peer review next week in a 4-day virtual meeting of the Scientific Advisory Committee on Chemicals (SACC) – despite numerous reasons why, in the midst of the current COVID-19 public health crisis, such a meeting simply will not provide the robust scientific review that this draft warrants.  EDF has urged EPA to postpone the SACC review so that it can be done under circumstances that are conducive to a proper review and fair to SACC members and stakeholders who would like to participate.

EDF submitted comments yesterday in order to meet the very tight deadline EPA set for comments if they are to be considered by the SACC.  Our comments raise numerous scientific deficiencies in EPA’s draft.  These flaws arise from a host of unwarranted and unsupported assumptions and methodological approaches that systematically lead EPA to understate the risks posed by this chemical to pregnant women, infants and children; to workers; to consumers; to the public; and to the environment.

Exposure to TCE is ubiquitous, coming from ambient and indoor air, vapor intrusion from contaminated sites, groundwater and drinking water wells, and food – yet EPA’s draft ignores or downplays each of these exposure sources and pathways.

It is vital that the current public health crisis caused by COVID-19 not be allowed to compromise the quality and integrity of scientific assessments of other critical public health risks we face.

Below I summarize some of the major concerns in EPA’s draft that we address in detail in our comments.  Read More »
