EPA proposes restrictions on toluene diisocyanates in consumer products.

/in , ,

Today, EPA released a proposed rule regulating toluene diisocyanates (TDI), a group of chemicals mainly used to make polyurethanes like the flexible foam in furniture, as well as other consumer products, including coatings and adhesives. According to the agency, diisocyanates are “well known dermal and inhalation sensitizers in the workplace and can cause asthma, lung damage, and in severe cases, death.” Today’s proposal is a Significant New Use Rule (SNUR) under the Toxic Substances Control Act (TSCA), and applies to the domestic manufacture, processing, or import of TDI in consumer products.

The proposed SNUR [PDF] designates as a “significant new use” the use of certain types of TDI in any consumer products; for three other types of TDI, the “significant new use” designation contains a carve-out for use in coatings, adhesives, elastomers, binders, and sealants at no greater than 0.1% by weight. Under the SNUR, manufacturers, processors, and importers would be required to notify EPA at least 90 days before beginning or resuming the manufacture, processing, or import of TDI in a consumer product. The 90-day period would allow the EPA to evaluate the potential uses for any associated risks or hazards.

Following a recent trend, EPA has proposed making inapplicable the general SNUR exemption for importing or processing the SNUR chemical as part of an article. In the proposal, EPA explains that the articles exemption “is based on an assumption that people and the environment will generally not be exposed to chemical substances in articles…. However, TDI and related compounds are volatile and as such could migrate out of articles that contain them.” The agency cites studies finding that TDI have migrated from products, leading to potential exposure.

EPA notes that TDI, also a high production volume chemical (HPV), are “widely used in residual amounts.” According to the proposed rule, TDI use in consumer products was not reflected in Chemical Data Reporting (CDR) data, and agency staff only learned of its use, at residual concentrations no more than 0.1% by weight, in coatings, adhesives, and similar products, from direct conversations with manufacturers and a review of published literature and Safety Data Sheets for products in stores. Moreover, due to expected growth in the market for such products, “EPA is concerned that consumer products in the future might contain amounts of TDI above [current] levels.”

The chemicals covered by the proposed SNUR are:

  • Toluene diisocyanate trimer
  • Poly(toluene diisocyanate)
  • Toluene diisocyanate dimer
  • Toluene diisocyanate “cyclic” trimer
  • 2,4-toluene diisocyanate
  • 2,6-toluene diisocyanate
  • Toluene diisocyanate unspecified isomer

EPA requests comment on the proposed SNUR, and is particularly interested in “whether there are any ongoing uses of these consumer products of which the Agency is currently unaware and would welcome specific documentation of any such ongoing uses.” The proposal released today is a prepublication version [PDF], and is expected to appear in the Federal Register in the next week or two; comments will be accepted within 60 days after the proposal’s Federal Register publication. Additional material may be found and comments may be filed on Regulations.gov using the proposed rule’s docket number: EPA-HQ-OPPT-2011-0976.

EPA sued over lack of nanosilver regulations.

/in , ,

On December 16, a group of NGOs sued [PDF] the U.S. EPA over the agency’s failure to regulate nanosilver in consumer products. The plaintiffs, which include the Center for Food Safety, Center for Environmental Health, and Beyond Pesticides, seek to compel EPA to take action in response to their 2008 petition for rulemaking. The groups’ petition requested that EPA regulate nanosilver products as pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), thus requiring product manufacturers to obtain pesticide registrations. The petition also asked EPA to analyze “the potential human health and environmental risks” of nanosilver under FIFRA and other environmental statutes, including the Endangered Species Act (ESA) and National Environmental Policy Act (NEPA).

Since the 2008 petition, EPA has accepted comments on the petition, enforced against companies making antimicrobial claims about nanosilver-containing products, convened a scientific advisory panel, and proposed a policy statement on the subject, but the NGOs maintain that EPA’s actions constitute an “ongoing failure to meaningfully regulate nanotechnology.” The plaintiffs contend that EPA has violated the Administrative Procedure Act by failing to provide a timely response to the 2008 petition.

The case is Center for Food Safety et al v. McCarthy, Case No. 14-cv-2131, in the U.S. District Court for the District of Columbia.

EPA finalizes SNURs, revokes articles exemption for benzidine dyes.

/in , ,

Today, EPA announced the promulgation of a final Significant New Use Rule (SNUR) [PDF] under Toxic Substances Control Act (TSCA) targeting three different chemical types: certain benzidine-based dyes, di-n-pentyl phthalate (DnPP), and alkanes, C12-13, chloro, a short-chain chlorinated paraffin (SCCP). Benzidine-based dyes can be used in textiles, paints, and inks; DnPP in PVC plastics; and alkanes in industrial lubricants. EPA found that all of the affected chemicals can cause health effects including aquatic toxicity, cancer, persistence and bioaccumulation, and reproductive and developmental effects.

Like other SNURs, the rule requires manufacturers (including importers) or processors of the identified substances to notify EPA at least 90 days before beginning any significant new use. Under this SNUR, any new use is considered a significant new use for the benzidine-based dyes and alkanes. For DnPP, EPA has designated “any use other than as a chemical standard for analytical experiments” as a significant new use. For the benzidine-based dyes, EPA is adding nine chemicals to an existing rule regulating benzidine-based chemicals.

Notably, the SNUR makes inapplicable the usual TSCA exemption for importing or processing chemicals as part of an article, calling it a “loophole.” Thus, 90-day notification will be required of importers or processors of any articles containing benzidine-based chemicals, encompassing both the nine newly-added dyes as well as those first regulated in 1996. The elimination of this articles exemption has been questioned by the chemical industry, and marks a shift in EPA’s policy. In today’s SNUR, the agency notes that it is “concerned that commencement of the manufacture (including import) or processing for any new uses, including resumption of past uses… could significantly increase the magnitude and duration of exposure to humans.”

Today’s rule is not the agency’s only effort at regulating these chemicals; benzidine dyes and SCCPs are both already subject to Action Plans, while other phthalates (not including DnPP), as well as medium-chain and long-chain chlorinated paraffins have been added for assessment under the TSCA Work Plan. SCCPs have been nominated for addition to the Stockholm Convention for Persistent Organic Pollutants, and manufacturing and importing in the U.S. has ceased following EPA enforcement actions in 2012. EPA also notes that its Design for the Environment program has identified safer dye and colorant alternatives on its Safer Chemical Ingredients List.

The SNUR will go into effect 60 days after its publication in the Federal Register, which will likely occur in the next week.

EPA finalizes Significant New Use Rules for ethylene glycol ethers.

/in , ,

In today’s Federal Register, the EPA has published a final Significant New Use Rule (SNUR) under the Toxic Substances Control Act (TSCA) for seven ethylene glycol ethers, also known as glymes. Glymes are used as industrial solvents or processing aids, and in some consumer products, such as inks, paints, coatings, adhesives, graffiti removers, and soldering compounds. The seven chemicals affected are:

  • monoethylene glycol dimethyl ether (monoglyme);

  • diethylene glycol dimethyl ether (diglyme);

  • diethylene glycol diethyl ether (ethyldiglyme);

  • triethylene glycol dimethyl ether (triglyme);

  • diethylene glycol dibutyl ether (butyl diglyme);

  • ethylene glycol diethyl ether (ethylglyme); and

  • triethylene glycol dibutyl ether (butyl triglyme).

The SNUR will require manufacturers (including importers) to notify EPA at least 90 days before starting any activity identified as a significant new use. For six of the glymes, the agency is designating all new consumer uses as significant new uses, while any new use constitutes a significant new use for the seventh glyme, triethylene glycol dibutyl ether (butyltriglyme). Three of the glymes subject to the SNUR contain carve-outs for certain uses, such as when diethylene glycol diethyl ether (ethyldiglyme) is used as a component of inks, coatings and adhesives, and as a component of paint/graffiti removers. In addition, in response to comments, EPA clarified that ethylene glycol ethers in brake fluid contained in a motor vehicle at point of sale would not be considered to have been “’sold or made available to consumers for their use,’ merely because it has been made available to motor vehicle manufacturers (as part of a brake fluid mixture for their use in manufacturing customers’ motor vehicles) or used car dealers.” Likewise, monoethylene glycol dimethyl ether (monoglyme) contained in sealed lithium batteries does not constitute use in a consumer product.

The agency is issuing this SNUR because glymes “have been shown to cause damage to reproductive organs and DNA, as well as toxicity to blood and blood forming organs.” EPA first proposed a SNUR for 14 glymes on July 12, 2011, but is not currently finalizing the rule for the other seven glymes “because the Agency believes that these chemicals are not sufficiently similar to the seven chemicals subject to this SNUR and therefore do not raise the same concern for potential exposure to these chemicals.”

EPA also notes that ethylene glycol dimethyl ether (monoglyme) is on the Work Plan for Chemical Assessments, because it met the criteria for priority assessment due to toxicity and use in commercial and consumer products. Under the Work Plan, EPA will conduct a risk assessment and determine if further risk reduction is necessary.

The SNUR goes into effect on February 17, 2015.

EPA invites submissions to add ingredients to Design for Environment Safer Chemical Ingredients List.

/in ,

Today, the EPA’s Office of Chemical Safety and Pollution Prevention announced a new initiative to expand the number of chemicals and functional use categories on its Design for Environment (DfE) Safer Chemical Ingredients List (SCIL). Under the new initiative, EPA is inviting manufacturers to voluntarily submit chemicals/ingredients for review and inclusion on the SCIL. Submitters must “fully disclose” the chemicals to the agency’s DfE program as well as to one of EPA’s authorized third-party profilers, who will compile a hazard profile for each chemical. After receiving the submission from the profiler, DfE will review the chemical profile to determine whether it meets DfE criteria for inclusion on the SCIL.

Interested manufacturers are instructed to contact one of the two authorized third-party profilers, NSF or ToxServices. For chemicals that would be the first ingredient in a component class, EPA also recommends requesting a consultation with the DfE program to discuss broader context implications before the SCIL evaluation takes place.

In addition, EPA encourages cleaning product formulators to participate in the independent CleanGredients program, noting that profiles prepared for SCIL screening may also be used to qualify for CleanGredients.

Industry group questions EPA's trend toward eliminating TSCA's articles exemption.

/in , ,

This week, Bloomberg BNA reported that American Chemistry Council attorneys recently met with representatives of the Office of Management and Budget (OMB) to ask that the Environmental Protection Agency (EPA) be required to conduct further information-gathering on a proposed rule under the Toxic Substances Control Act (TSCA) that would regulate benzidine-based dyes, among other chemicals. The proposed Significant New Use Rule (SNUR), published in March 2012, would add nine chemicals to the SNUR already listed at 40 C.F.R. § 721.1660 and make unavailable the customary “articles exemption,” which exempts persons processing or importing the regulated chemicals as part of an article. Under this SNUR, importers or processors of articles containing benzidine-based dyes would have to provide 90-day advance notice to EPA. According to Bloomberg BNA, the ACC told OMB of its concern that the proposed SNUR “lacked a rationale explaining how or why the EPA decided it was necessary to regulate articles rather than focus solely on chemicals as it typically does in new use rules.”

In its June 2012 comments on the proposed rule, the ACC noted that the proposed revocation of the articles exemption “herald[s] a shift by the Agency towards greater regulation of chemicals in articles.” The ACC argued that removing the articles exemption “should be limited to exceptional circumstances” and be “based on sound criteria,” and recommended that EPA “define a clear policy framework including criteria for determining when TSCA regulation of articles is appropriate. In any proposed SNUR, the Agency should present a compelling basis for a decision to apply a SNUR to articles.”

The OMB’s Office of Information and Regulatory Affairs (OIRA) reviews all significant rulemaking before publication, and may return an agency rule for further consideration and review if, for example, OIRA finds that the proposed rule is not justified by the analysis.

The articles restriction in the benzidine-based dyes SNUR is in line with other recent SNURs regulating articles; Bloomberg BNA reports that since 2012, EPA has proposed at least four SNURs that would eliminate the articles exemption for certain chemicals, including the 2013 rule on carpets containing long-chain perfluoralkyl carboxylates.

EPA promulgates 52 SNURs.

/in , ,

In today’s Federal Register, the EPA published Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA) applying to 52 chemical substances, ranging from “functionalized carbon nanotubes” to amine adducts. The affected chemicals were all subject to Premanufacture Notices (PMNs), and nine are also subject to consent orders under TSCA § 5(e). Today’s SNURs extend the provisions of the § 5(e) consent orders and require manufacturers and processors of the chemicals to notify EPA prior to engaging in any activity designated in the rules as a significant new use. The SNURs were issued by Direct Final Rule, meaning that the SNURs will go into effect in 60 days unless EPA receives written adverse or critical comments, or notice of intent to submit such comments, by November 26.

EPA updates TSCA Work Plan, 23 chemicals added to list for further review.

/in , ,

Today, EPA released its first update [PDF] to the Toxic Substances Control Act (TSCA) Work Plan for Chemical Assessments. Drawing on new data collected through Chemical Data Reporting (CDR) and the Toxic Release Inventory program, EPA adjusted the exposure rankings for the chemicals initially screened for the Work Plan and added 23 chemicals to the Work Plan list for further assessment. The agency also removed 15 chemicals which are mostly no longer in commerce; of the 15, mercury (and mercury compounds) and quartz were removed because risks associated with those substances are already sufficiently managed. In addition, benzo[a]pyrene was designated to be evaluated as part of the assessment of creosote. Today’s changes had no effect on 67 chemicals and bring the Work Plan total to 90 chemicals.

Included in the 23 new Work Plan chemicals, EPA added the following five Action Plan chemicals or chemical groups to the Work Plan for further assessment:

  • Bisphenol A (BPA)
  • Decabromodiphenyl ether (decaBDE)
  • Hexabromocyclododecane (HBCD)
  • Nonylphenols and nonylphenol ethoxylates (NP/NPE)
  • Group of phthalates (dibutyl phthalate (DBP), butyl benzyl phthalate (BBP), di(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DnOP), di-isononyl phthalate (DINP), di-isodecyl phthalate (DIDP), and di-isobutyl phthalate (DIBP)

These Action Plan chemicals were all identified as highly-ranked for hazard and exposure; decaBDE and HBCD also had high rankings for persistence/bioaccumulation. The other five Action Plan chemicals not added to the Work Plan were not selected for reasons including lower toxicity and potential exposure or because they are no longer produced or imported into the United States. Of these non-Work Plan chemicals, the agency plans to propose Significant New Use Rules (SNURs) for benzidene dyes and toluene diisocyanate (TDI). In the case of long-chain perfluorinated chemicals (PFCs), EPA noted that while it has already begun risk management actions, including a voluntary stewardship program, it intends to gather “additional data regarding use of PFCs in imported articles before determining if these chemicals should be candidates for the assessment process.”

In addition to the Action Plan chemicals, EPA added ten chemicals which were previously screened for the Work Plan in 2012. These ten chemicals now have increased exposure scores, according to recent CDR and TRI data, due to “being domestically produced or imported in greater quantities and …used in a larger variety of consumer and children’s products.” Two flame retardants, triphenyl phosphate (TPP) and isopropylated phenol, phosphate (iPTPP), were also added.

U.S.-Canada joint consultation process for new substances in the works.

/in ,

Last week, Chemical Watch reported that the U.S. EPA and Environment Canada are developing a joint process that will allow “companies planning to introduce a new substance in both countries to approach both governments simultaneously.” The joint consultation process, called the North American Notification Consultation (Nan-C), was described by an Environment Canada official on October 8 at a conference in Mississauga, Canada. Although it is still in an early stage of development, the official described it as based on the OECD’s “Parallel Process” standard operating procedures for new substance notifications. One company is already participating in the Nan-C process, and other companies interested in trying it are encouraged to contact Environment Canada through their substances management information line.

The idea for the process reportedly emerged from a nanotechnology workshop held earlier this year by the US-Canada Regulatory Cooperation Council. However, Environment Canada representatives stressed that Nan-C is not meant to replace the OECD parallel process, but is simply a more streamlined and bilateral version specific to the U.S. and Canada. Nan-C is also not a wholly new process, since bilateral consultation is already an option – instead, it is a response to a perceived need among stakeholders for a more formalized version of a pre-existing mechanism.

EPA's ChemView database updated with new chemical SNURs and consent orders.

/in , , , , ,

Yesterday, EPA announced updates to ChemView, its public online tool for accessing information about chemicals regulated under the Toxic Substances Control Act (TSCA). The updates include enhanced data functions as well as updated, more comprehensive information.

The improved data functions include:

  • Improving the display and content for the Chemical Data Reporting information;
  • Adding a new link that displays the pollution prevention information generated as part of the Toxics Release Inventory program; and
  • Launching an administrative tool that will save EPA resources by streamlining the loading of future information.

ChemView’s databases were updated with the following new information:

  • 244 consent orders;
  • An additional 1,205 Significant New Use Rules (SNURs) for new and existing chemicals;
  • 16 additional chemicals with test rule data, and
  • Updates to the Safer Chemicals Ingredient List (part of the agency’s Design for Environment program).

In EPA’s press release, Assistant Administrator for the Office of Chemical Safety and Pollution Prevention Jim Jones explained that the agency was acting since Congress’ attempts to reform TSCA have so far been unsuccessful: “In the absence of TSCA reform, EPA is moving ahead to improve access to chemical health and safety information, and increase the dialogue to help the public choose safer ingredients used in everyday products.”

With the updates, ChemView now covers 10,000 chemicals and includes for the first time consent orders and new chemical SNURs. ChemView was first launched in 2013 to improve the availability of information on existing chemicals by displaying “key health and safety information and uses data in a format that allows quick understanding.”
