The Trump EPA is setting back chemicals policies by decades

Tacoma, WA 1972

As we approach the third anniversary of the historic passage of bipartisan legislation to overhaul our nation’s broken chemical safety system, we’re hearing that political appointees at the agency are gearing up to celebrate their “successes” in implementing the law.

Even more disturbing than its individual actions are the methodical steps the Trump EPA is taking to dismantle decades of progress in our country’s chemicals policies.

While the chemical industry may well have things to celebrate, it’s simply not the case for the rest of us:  Comments from former top EPA officialsmembers of Congressstate and local governments, labor groupsfirefighterswater utilitiespublic health groups, and a broad range of environmental groups make crystal clear that there’s nothing warranting celebration.  EPA’s actions are threatening the health of American families.

But as I reflect on how implementation of the Toxic Substances Control Act (TSCA) has gone off the rails under the Trump EPA, even more disturbing than its individual actions are the methodical steps it is taking to dismantle decades of progress in our country’s chemicals policies.  In this post, I’ll briefly highlight five such policies and how this EPA is undermining them:

  • Pollution prevention
  • Inherent safety and hazard reduction
  • Protection of vulnerable subpopulations and environmental justice
  • Holistic, real-world risk assessment
  • Public right to know

The Trump EPA is illegally denying requests for public files on new chemicals

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

For some time now, Environmental Defense Fund (EDF) has been requesting “public files” of new chemical notices the Environmental Protection Agency (EPA) receives under the Toxic Substances Control Act (TSCA).  The process is kludge-y to say the least.  We have to email our request to EPA’s Docket Center, and, typically, several weeks later the staff there copy the files that staff in the TSCA office have given them in response to our request onto a CD-ROM and snail-mail it to us.

This, despite the fact that EPA’s own regulations (see here and here) state unequivocally that EPA is to promptly make new chemicals’ premanufacture notifications (PMNs) and associated documents broadly available to the general public by posting them to electronic dockets.  One regulation states: “All information submitted with a notice, including any health and safety study and other supporting documentation, will become part of the public file for that notice, unless such materials are claimed confidential.”  The other regulation states that public files are to be made available in the electronic docket posted at http://www.regulations.gov.

We have blogged extensively about how, even once we receive the public files, they are rife with wholesale omissions, illegal redactions and myriad other problems.

After two years of our repeated requests to EPA to comply with its own regulations, it appears EPA may be taking a first step to try do so:  EPA recently announced (via email, but not anywhere on its website that we can find) that it will start posting PMNs and associated documents it receives in the future to its ChemView database, within 45 days of their receipt.  While this could be a welcome development, it does nothing to remedy EPA’s failure to provide access to the thousands of PMNs it has received in the past.  And it remains to be seen what EPA actually will and won’t be posting.

We’ll be watching closely to see when and what EPA actually makes available.  Part of the need for vigilance comes from a disturbing response we’ve been receiving from EPA’s Docket Center to some recent requests for new chemical public files:   Read More »

EPA distorts the scientific evidence and fails to protect kids’ brains in its proposed limit for perchlorate in drinking water

Tom Neltner, J.D.is Chemicals Policy Director and Maricel Maffini, Ph.D., Consultant

Today, the Environmental Protection Agency (EPA) proposed a Maximum Contaminant Level (MCL) of 56 parts per billion (ppb) for perchlorate in drinking water – more than three times less protective than an interim health advisory level set in 2008. To justify this increase, EPA turned its back on scientific evidence showing that this potent neurotoxin undermines childrens’ motor development and control and can increase their anxiety and depression. The agency’s reasoning is inconsistent with its own analysis published in a draft report in late 2017 and the findings of a peer review panel it convened last year to review that report.

If the agency had used the most protective scientific study and the most sensitive endpoint evaluated in the proposed rule, the MCL would likely be 4 ppb – more than three times more protective than the current health advisory. As a result, the agency fails to adequately protect children from a lifetime of harm. With this MCL, EPA is allowing pregnant women to be exposed to perchlorate in the first trimester of pregnancy at levels that pose much greater risk of impaired neurodevelopment in their children.

The proposed MCL – and how the agency reached it – was both a disappointment and a surprise to us. In late 2017, we applauded the agency’s scientists for developing an innovative model connecting a mother’s perchlorate exposure in the first trimester to fetal harm. We were not alone – in early 2018, EPA’s peer review panel congratulated the agency’s scientists on their analysis. We also complimented EPA’s population-based approach to developing an MCL by estimating the percent of pregnant women, and their children, with borderline thyroid dysfunction due to low iodine intake.

So how did EPA abruptly change course and estimate an MCL less protective than the current health advisory? By altering its analysis in three subtle but significant ways:

  1. Rejecting five epidemiology studies showing harm at even lower exposure levels in favor of one IQ study by Korevaar et al. in 2016.
  2. Choosing an MCL that allows an IQ loss of 2 points even though the study showed a 1 point loss was statistically significant.
  3. Dismissing an alternative, population-based method that EPA proposed in 2017 that reinforces the need for a more protective standard.

Company safety data sheets on new chemicals frequently lack the worker protections EPA claims they include

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

Readers of this blog know how concerned EDF is over the Trump EPA’s approval of many dozens of new chemicals based on its mere “expectation” that workers across supply chains will always employ personal protective equipment (PPE) just because it is recommended in the manufacturer’s non-binding safety data sheet (SDS).

How much farther under the bus will the Trump EPA throw American workers?

The typical course has been for EPA to identify risks to workers from a new chemical it is reviewing under the Toxic Substances Control Act (TSCA), but then – instead of issuing an order imposing binding conditions on the chemical’s entry onto the market, as TSCA requires – to find that the chemical is “not likely to present an unreasonable risk” and impose no conditions whatsoever on its manufacturer.  This sleight of hand is pulled off by EPA stating that it:

expects employers will require and workers will use appropriate personal protective equipment (PPE) … consistent with the Safety Data Sheet prepared by the new chemical submitter, in a manner adequate to protect them.

We have detailed earlier the myriad ways in which this approach strays from the law, is bad policy and won’t protect workers.  But here’s yet another gaping problem:  When we are able to look at the actual SDSs – that is, when EPA has made them available and when they are not totally redacted – we are frequently finding that the specific PPE that EPA claims to be specified in the SDSs – and that EPA asserts is sufficient to protect all workers handling the chemical – is not in the SDSs.   Read More »

Round 2 on PV29 reveals even deeper flaws in EPA’s TSCA risk evaluation of the chemical

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

On Friday, Environmental Defense Fund (EDF) submitted a new set of extensive comments to the Environmental Protection Agency (EPA) in response to its March release of additional information on Pigment Violet 29 (PV29), the first chemical to undergo a risk evaluation under the Toxic Substances Control Act (TSCA) following the law’s amendment in 2016.

After EDF and others criticized both the dearth of health and environmental data on PV29, and EPA’s illegal withholding of those data, EPA released some additional information and opened a new comment period in mid-April.  In releasing the new information, EPA was quick to judgment, asserting that “[t]he release of these studies does not change the Agency’s proposed ‘no unreasonable risk’ determination as concluded in the draft risk evaluation published in November.”

EDF’s 100 pages of comments in Round 1 enumerated the myriad ways EPA has failed to demonstrate that PV29 does not present unreasonable risk.  Unfortunately, if anything, Round 2 has only deepened our concerns over the inadequacy of EPA’s risk evaluation.   Read More »

EPA says PV29 is perfectly safe. The EU, citing concerns and a dearth of data, begs to differ.

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

In contrast to the Environmental Protection Agency’s (EPA) asserted clean bill of health for Pigment Violet 29 (PV29) in its draft risk evaluation, authorities under the European Union’s REACH program have formally declared the chemical to be a suspected persistent, bioaccumulative and toxic (PBT) substance and a suspected very persistent and very bioaccumulative (vPvB) substance.  Either designation, if confirmed, would classify PV29 as a substance of very high concern (SVHC) under the EU’s REACH Regulation.

In EDF’s earlier comments on EPA’s draft risk evaluation, we noted that PV29 had been proposed to be so listed under REACH and to undergo a full substance evaluation in 2021.  Since we filed those comments, the European Chemicals Agency (ECHA) has published an update to its Community Rolling Action Plan (CoRAP) that now formally designates PV29 as a “suspected PBT/vPvB” that will be subject to a full substance evaluation.  The listing is accompanied by a “justification document” for PV29’s designation.

The justification document, prepared by the Belgian Competent Authority (BE CA) under REACH and endorsed by REACH authorities, echoes many of the concerns about PV29 and EPA’s draft risk evaluation that EDF had raised in our earlier comments.   Read More »
