Yesterday, EPA proposed a rule to ban methylene chloride and either ban or restrict the use of N-methylpyrrolidone in paint stripping products, subject to certain national security exemptions. This proposal is the third such proposed action by the agency in the past month (see here and here). Below, find a short description of these chemicals and EPA’s proposed actions.

The Environmental Defense Fund applauds the Environmental Protection Agency (EPA) for meeting a major milestone in implementing the Frank R. Lautenberg Chemical Safety for the 21st Century Act, the landmark legislation reforming the Toxic Substances Control Act (TSCA) that passed in June 2016 with overwhelming bipartisan support.
EPA reached this milestone this week when it released proposals for the three foundational rules that the Lautenberg Act mandates be finalized by June of this year, as well as three proposed rules restricting specific high-risk uses of several chemicals.
The management and staff of EPA’s Office of Chemical Safety and Pollution Prevention and Office of General Counsel deserve major kudos for their tireless work over these past seven months to reach this milestone. This should also bring satisfaction to the Members of Congress who authored the Lautenberg Act and included aggressive deadlines as part of the bipartisan effort to reform the law. Read More

The Environmental Protection Agency (EPA) took another significant step yesterday to protect against exposures to the highly toxic chemical, trichloroethylene (TCE), proposing a rule to ban its use as a vapor degreaser.
The proposed rule is the second issued under section 6 of the Toxic Substances Control Act (TSCA) as amended by last year’s Lautenberg Act. It follows on EPA’s proposed rule last month to ban the use of TCE as an aerosol degreaser and spot cleaning agent in dry cleaning facilities. Both proposed rules on TCE are critical to protecting consumer and worker health from the harmful effects of TCE and should move swiftly toward finalization. Read More

Today, EPA issued its long-awaited rule to gather risk-relevant information on nanoscale materials. The new rule will finally allow EPA to obtain basic data on use, exposure, and hazards from those that manufacture or process these materials, which has long been recognized by experts as essential to understand and manage their potential risks.
Nanomaterials – a diverse category of materials defined mainly by their small size – often exhibit unique properties that can allow for novel applications but also have the potential to negatively impact our health and the environment. Some nanomaterials: more easily penetrate biological barriers than do their bulk counterparts; exhibit toxic effects on the nervous, cardiovascular, pulmonary, and reproductive systems; or have antibacterial properties that may negatively impact ecosystems or lead to resistance.

[UPDATE 1/17/17: Today EPA posted a full transcript of the public comments made at its December 14, 2016, meeting, along with the presentations made by EPA staff. MP3 audio files of the public comments are already posted (note they are huge files).]
EPA held a public meeting Wednesday on the implementation of the New Chemicals Review Program under the reformed Toxic Substances Control Act (TSCA). The Frank R. Lautenberg Chemical Safety for the 21st Century Act required EPA to begin implementation of the reforms to the program on the day the legislation was signed into law. The meeting was an opportunity to discuss the effort and progress to date.
As we’ve noted before, and as I noted on Wednesday, the changes made to the New Chemicals Review Program were fundamental to TSCA reform and the promise of a new system that better protects public health and the environment.
Representatives from state government, the Senate, NGOs, and industry gathered to hear a series of presentations by EPA about new chemicals reviews under the reformed law, scientific and data issues the Agency is navigating, and the types of information it needs from manufacturers and processors to facilitate a streamlined review process.
A series of oral comments from various stakeholders included a robust showing of support for EPA’s actions from public interest groups representing labor, the environment, and public health, as well as concerns from some in industry with certain aspects of implementation. EPA concluded with a commitment to meet again in six months to discuss its progress in implementing revisions to the New Chemicals Review Program.

All Americans who have been tested have perchlorate in their bodies. Perchlorate threatens fetal and child brain development by impairing the thyroid’s ability to transport iodine in the diet into the gland to make a thyroid hormone, known as T4, that is essential to brain development. Both the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) are scheduled to make decisions in 2017 that could significantly reduce exposure to this hazardous chemical.
Based on statements in a new report by EPA, we estimate that at least 20% of pregnant women are already iodine deficient, resulting in T4 levels that put the fetuses’ developing brains at risk. For this population of pregnant women, any perchlorate exposure results in an even greater risk of impaired brain development in their children and potentially a lifetime of behavioral and learning difficulties.
This is why it is critical that our public health agencies take actions to reduce exposure to perchlorate with a focus on this vulnerable population. There are three key decisions to be made in the coming year:
- EPA will decide in January 2017 whether hypochlorite bleach, an antimicrobial pesticide, degrades to perchlorate in significant amounts. If EPA agrees it does, the agency must set standards to limit that degradation as part of its 15-year update to the pesticide’s registration. Bleach is a widely-used disinfectant in food manufacturing facilities and likely a significant source of perchlorate in contaminated foods. Research shows that reducing hypochlorite concentration limits degradation and this, coupled with expiration dates on the product would significantly reduce exposure to perchlorate.
- FDA will decide whether perchlorate should continue allowing perchlorate to be added to plastic packaging for dry food at levels up to 12,000 ppm to reduce buildup of static charges. The agency has evidence that the perchlorate migrates from the packaging into food, especially when it flows in and out of the container. In response to a lawsuit filed by public interest organizations, FDA told a court that it aims to make a final decision by the end of March 2017. A 2008 report by FDA indicated that almost 75% of all food types are contaminated with perchlorate.
- EPA told a court that it will complete external peer review of a dose-response model in October 2017 and sign a proposed rule to regulate perchlorate in drinking water a year later. This model is a critical step in establishing a drinking water standard for perchlorate pursuant to its 2011 determination that an enforceable standard was necessary under the Safe Drinking Water Act. The perchlorate is most likely from contaminated source waters (e.g. from military and defense industry activities and some fertilizer use in agricultural regions) or from degradation of hypochlorite bleach used to disinfect water. EPA acted in response to a lawsuit by the Natural Resources Defense Council.
To guide their decision-making, FDA and EPA collaborated to develop a biologically-based dose-response model to predict T4 levels in pregnant women, fetuses, and infants exposed to perchlorate. EDF and NRDC submitted joint comments on the model and the summary report requesting that EPA ensure protection of fetuses during the first two trimesters for pregnant women with serious iodine deficiencies. These fetuses are particularly vulnerable because their thyroids is not yet functioning. The current fetal model only considers the third trimester when the fetus has a functioning thyroid. The current model fails to adequately protect their vulnerable subpopulations, falling shot of both the EPA's Science Advisory Board recommendation and the Safe Drinking Water Act requirements.
For decades, federal agencies have been charged with protecting children from environmental health risks with the recognition that they are uniquely vulnerable to chemical exposures. The upcoming decisions on perchlorate present critical opportunities to protect what many of us value the most—our children’s health and their ability to learn and thrive to their fullest potential.
