EPA Proposes a Second SNUR for Multi-Walled Carbon Nanotubes

The U.S. Environmental Protection Agency (EPA) published on February 3, 2010, a proposed significant new use rule (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for multi-walled carbon nanotubes. The proposed rule would require persons who intend to manufacture, import, or process the substance for an activity that is designated as a significant new use by the proposed rule to notify EPA at least 90 days before commencing that activity. EPA states that the required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. Comments are due March 5, 2010.

The proposed rule provides the following basis for action:

The PMN states that the substance will be used as an additive/filler for polymer composites and support media for industrial catalysts. Based on test data on analogous respirable, poorly soluble particulates and on other carbon nanotubes (CNTs), EPA identified concerns for lung effects, immunotoxicity, and mutagenicity from exposure to the PMN substance. For the uses described in the PMN, worker inhalation and dermal exposures are minimal due to the use of adequate personal protective equipment. Therefore, EPA has not determined that the proposed manufacturing, processing, or use of the substance may present an unreasonable risk. EPA has determined, however, that use of the substance without the use of gloves and protective clothing, where there is a potential for dermal exposure; use of the substance without a National Institute for Occupational Safety and Health (NIOSH)-approved full-face respirator with an N100 cartridge, where there is a potential for inhalation exposure; or use other than as described in the PMN, may cause serious health effects. Based on this information, the PMN substance meets the concern criteria at 721.170(b)(3)(ii).

The proposed SNUR would apply only to the multi-walled carbon nanotubes described in premanufacture notice (PMN) P08-199. According to EPA, in the past, some stakeholders have asked whether these types of SNURs apply to all variants of carbon nanotubes. EPA states: “This is not the case.” The chemical name listed in the proposed SNUR is “multi-walled carbon nanotubes (generic),” and the CAS Number is “not available.” On November 6, 2009, EPA published a proposed SNUR for the multi-walled carbon nanotubes described in PMN P08-177.

EPA Proposes SNURs for Carbon Nanotubes

On November 6, 2009, the U.S. Environmental Protection Agency (EPA) proposed significant new use rules (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for two chemical substances that were the subject of premanufacture notices (PMN). EPA identified the substances generically as multi-walled carbon nanotubes and single-walled carbon nanotubes. According to the notice, these substances are subject to TSCA Section 5(e) consent orders issued by EPA. The consent orders require protective measures to limit exposures or otherwise mitigate the potential unreasonable risk. The proposed SNURs are based on and consistent with the provisions in the underlying consent orders, and designate as a significant new use the absence of the protective measures required in the corresponding consent orders. Persons who intend to manufacture, import, or process either of these two substances for an activity that is designated as a significant new use would be required by the proposed rule to notify EPA at least 90 days before commencing that activity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. Comments are due December 7, 2009.

ITC Issues Priority Testing List Report

In a notice in the August 4, 2009, Federal Register, the Toxic Substances Control Act (TSCA) Interagency Testing Committee (ITC) released its latest report to the Administrator. Under TSCA Section 4(e), the ITC is required ‘‘to make recommendations to the Administrator respecting the chemical substances and mixtures to which the Administrator should give priority consideration for the promulgation of rules for testing.” According to the report, “the ITC has no revisions to the TSCA section 4(e) Priority Testing List at this time.”

The report also describes the ITC’s emphasis during the reporting period (November 2008 to May 2009) on nanoscale materials and how best to regulate them. It summarizes the ITC’s recent reviews of the U.S. Environmental Protection Agency’s (EPA) Nanoscale Materials Stewardship Program’s interim report and the National Institute for Occupational Safety and Health’s (NIOSH) nanotechnology guidelines. The report concludes by recommending data needs of ITC organizations be addressed and lists many of the data deficiencies.

EPA Clarifies Final CNT SNURs

On July 28, 2009, the U.S. Environmental Protection Agency (EPA) clarified its June 24, 2009, final Significant New Use Rules (SNUR) for multi- and single-walled carbon nanotubes (CNT).  According to EPA, upon review of the final rule, stakeholders asked whether the SNURs applied to all types of CNTs.  EPA responded:

 

This is not the case.  These SNURs only apply to the specific carbon nanotubes that were the subject of the premanufacture notices (PMN) submitted under Section 5 of TSCA and not to any other carbon nanotubes.  Other carbon nanotubes must be notified through EPA's New Chemicals Program.  The U.S. EPA strongly encourages all manufacturers and importers of nanoscale materials that are intended for commercial use to consult with the Agency in advance of production or importation.

EPA Considering Test Rule For Multiwall CNTs

According to a notice in the U.S. Environmental Protection Agency's (EPA) May 11, 2009, Regulatory Agenda, a Toxic Substances Control Act (TSCA) Section 4(a) test rule “may be needed to determine the health effects” of multiwall carbon nanotubes (CNT). EPA states that the results of the tests that could be required under the rule could assist in understanding the health effects of the substance to manage/minimize any potential risk and exposure. Results could also help with establishing a correlation between the chemical/physical properties and health effects needed to protect the health of workers handling the substance. EPA has not determined when it will publish a notice of proposed rulemaking (NPRM).

EPA Publishes NMSP Interim Report

On January 12, 2009, the U.S. Environmental Protection Agency (EPA) released
its interim report on the Nanoscale Materials Stewardship Program (NMSP), which is a
voluntary program that EPA established to assemble existing data and information from
manufacturers and processors of certain nanoscale materials. Under the Basic Program, EPA
invited participants to voluntarily report available information on the engineered nanoscale
materials they manufacture, import, process, or use. As of December 8, 2008, 29 companies or
associations submitted information to EPA covering 123 nanoscale materials and a further seven
companies have outstanding commitments to the Basic Program. Under the In-Depth Program,
EPA invited participants to work on a plan for the development of data on representative
nanoscale materials over a longer time frame. As of December 8, 2008, four companies have
agreed to participate. EPA states that, based on the current interim results, “the NMSP can be
considered successful.” EPA notes that a number of the environmental health and safety data
gaps still exist, however, and “EPA is considering how to best use testing and information
gathering authorities under the Toxic Substances Control Act [(TSCA)] to help address those
gaps.”

EPA Announces Receipt of CNT PMNs

In a January 5, 2009, Federal Register notice, the U.S. Environmental Protection Agency (EPA) announces receipt of several premanufacture notices (PMN) concerning multi-walled carbon nanotubes (CNT). Under Section 5 of the Toxic Substances Control Act (TSCA), EPA requires any person who intends to manufacture (defined by statute to include import) a new chemical (i.e., a chemical not on the TSCA Inventory) to notify EPA and comply with the statutory provisions pertaining to the manufacture of new chemicals. According to the notice, EPA received the CNT PMNs on September 17, 2008, and the projected end date was December 15, 2008. The submitter name is claimed as confidential business information (CBI). Comments on the PMNs are due February 4, 2009.

EPA Regulatory Agenda Includes Item on Nanoscale Materials Stewardship Program

According to a notice in the U.S. Environmental Protection Agency’s (EPA) November 24, 2008, Regulatory Agenda, EPA intends to publish an interim evaluation in March 2009 of the Nanoscale Materials Stewardship Program (NMSP), and a final evaluation of the NMSP, including next steps, in April 2010. The NMSP is a voluntary program that EPA established to assemble existing data and information from manufacturers and processors of certain nanoscale materials. The notice states that, under the Toxic Substances Control Act (TSCA), EPA has the authority to require the development of data necessary for risk assessment when statutory findings concerning (1) production volume and exposure/entry into the environment or (2) potential hazard can be made, and to prevent and eliminate unreasonable risk of injury to human health and the environment.

EPA Posts TSCA 8(e) Submission for Carbon Nano Tubes

Last week, the U.S. Environmental Protection Agency posted a submission made by BASF Chemical Company under Section 8(e) of the Toxic Substances Control Act (TSCA), which requires U.S. chemical manufacturers, importers, processors and distributors to notify EPA within 30 calendar days of new, unpublished information on their chemicals that may lead to a conclusion of substantial risk to human health or to the environment. In its July 8, 2008, submission, BASF submitted the results of a subchronic inhalation study in rats, reporting that the no observed effect concentration is below 0.1 mg/m3. In a September 9, 2008, letter, EPA’s Office of Pollution Prevention and Toxics (OPPT) states that it conducts preliminary screens of all Section 8(e) submissions and routinely requests additional information from submitters to complete these preliminary screens or to evaluate submissions further. OPPT requested the complete report from BASF.

EPA Will Publish Notice Regarding TSCA Inventory Status of Carbon Nanotubes

According to the Office of the Federal Register, tomorrow the U.S. Environmental Protection Agency (EPA) will publish a notice regarding the Toxic Substances Control Act (TSCA) requirements potentially applicable to carbon nanotubes (CNT). EPA states that it “generally considers CNTs to be chemical substances distinct from graphite or other allotropes of carbon listed on the TSCA Inventory.” As a result, many CNTs may therefore be new chemicals under TSCA Section 5. Manufacturers or importers of CNTs not on the TSCA Inventory must submit a premanufacture notice (PMN) (or applicable exemption) under TSCA Section 5 where required under 40 C.F.R. Part 720 or Part 723. To determine the TSCA Inventory status of a CNT, a manufacturer may submit to EPA a bona fide intent to manufacture or import under 40 C.F.R. Section 720.25.  According to the notice, some time after March 1, 2009, EPA anticipates focusing its compliance monitoring efforts to determine if companies are complying with TSCA Section 5 requirements for CNTs.

EPA Prepared to Issue TSCA Section 8 Rule to Obtain Data

On July 22, 2008, Jim Willis stated that the U.S. Environmental Protection Agency (EPA) is prepared to issue a rule under Section 8 of the Toxic Substances Control Act (TSCA) to obtain data regarding nanoscale materials. Under the Nanoscale Materials Stewardship Program (NMSP) Basic Program, EPA asked companies to report data voluntarily on the engineered nanoscale materials they manufacture, import, process, or use. As of July 22, 2008, manufacturers of approximately 60 nanoscale materials had responded to EPA that they would participate in the NMSP. Willis stated that he hoped more companies would participate, so that data on about 100 nanoscale materials would be provided. The deadline for submissions under the Basic Program is July 28, 2008.

EPA invites companies that manufacture, import, process, or use nanoscale materials for commercial purposes to join the NMSP, including those who:

  • Manufacture or import engineered nanoscale materials;
  • Physically or chemically modify or process an engineered nanoscale material;
  • Physically or chemically modify or process a non-nanoscale material to create an engineered nanoscale material; or
  • Use engineered nanoscale materials in the manufacture of a product.
EPA also invites others, including researchers who develop or study engineered nanoscale materials, to participate. Any participation in the NMSP is voluntary.

EPA Unified Agenda Includes Item on Nanoscale Materials Stewardship Program

The U.S. Environmental Protection Agency’s (EPA) May 5, 2008, Unified Agenda includes an item regarding the Nanoscale Materials Stewardship Program (NMSP), which is a voluntary program that EPA established to assemble existing data and information from manufacturers and processors of certain nanoscale materials. The notice states that, under the Toxic Substances Control Act (TSCA), EPA has the authority to require the development of data necessary for risk assessment when statutory findings concerning (1) production volume and exposure/entry into the environment or (2) potential hazard can be made, and to prevent and eliminate unreasonable risk of injury to human health and the environment. On January 28, 2008, EPA announced the NMSP. According to the Unified Agenda notice, EPA intends to publish in March 2009 an interim evaluation of the NMSP, and a final evaluation of the NMSP, “including next steps,” in April 2010.

EPA Announces Voluntary NMSP

In today’s Federal Register, the U.S. Environmental Protection Agency (EPA) published a notice describing the design and format of EPA’s voluntary Nanoscale Materials Stewardship Program (NMSP) for nanoscale materials under the Toxic Substances Control Act (TSCA). EPA intends the NMSP “to complement and support its new and existing chemical efforts on nanoscale materials” under TSCA. Participants may participate in a basic program by submitting existing data, or may participate in an in-depth program to test engineered nanoscale materials. EPA intends to publish a summarized interim report approximately one year after the initiation of the NMSP, which will be based on data reported during the first six months of the basic program. EPA will then develop a more detailed report reflecting its evaluation of the NMSP approximately two years after initiation of the NMSP.

TSCA and Engineered Nanoscale Substances

Bergeson & Campbell, P.C. is pleased to announce that Lynn L. Bergeson and Ira Dassa published an article appearing in the Fall 2007 issue of Sustainable Development Law and Policy. The article discusses several issues in connection with the application of the Toxic Substances Control Act (TSCA) to engineered nanoscale materials.

EPA Unified Agenda Includes Item on Nanoscale Materials Stewardship Program

The U.S. Environmental Protection Agency’s (EPA) December 10, 2007, Unified Agenda includes a notice regarding the Nanoscale Materials Stewardship Program (NMSP), which is a voluntary program that EPA established to assemble existing data and information from manufacturers and processors of certain nanoscale materials. The notice states that, under the Toxic Substances Control Act (TSCA), EPA has the authority to require the development of data necessary for risk assessment when statutory findings concerning (1) production volume and exposure/entry into the environment or (2) potential hazard can be made, and to prevent and eliminate unreasonable risk of injury to human health and the environment. On July 12, 2007, EPA announced the availability of an NMSP concept paper, a proposed information collection request (ICR), and a paper that describes determining the TSCA Inventory status of nanoscale materials. According to the Unified Agenda notice, EPA intends to publish in February 2008 a final NMSP notice, including final versions of any documents.

EPA Holds Public Meeting on the NMSP

On August 2, 2007, the U.S. Environmental Protection Agency (EPA) convened a public meeting on the Nanoscale Materials Stewardship Program (NMSP) under the Toxic Substances Control Act (TSCA). The meeting, which EPA had announced in a July 12, 2007, Federal Register notice, was well attended, with approximately 100 people in attendance. After introductory remarks by several EPA officials, various organizations presented their views on the NMSP and the associated draft documents made available by EPA on July 12, 2007. Among those offering comments were the American Chemistry Council (ACC) Nanotechnology Panel, Environmental Defense (ED), Consumers Union, the NanoBusiness Alliance, the International Council on Nanotechnology, and Dr. J. Clarence Davies of the Project on Emerging Nanotechnologies (PEN).

EPA Will Hold NMSP Public Meeting and Releases Draft Documents

On June 9, 2007, the U.S. Environmental Protection Agency (EPA) signed three Federal Register notices related to the Nanoscale Materials Stewardship Program (NMSP) under the Toxic Substances Control Act (TSCA) (appended). EPA intends to publish the notices in the July 12, 2007, Federal Register. The first notice announces a public meeting on August 2, 2007, to receive comments on the development of the voluntary NMSP. The second notice announces the availability of two draft documents for public review and comment: (1) “Concept Paper for the Nanoscale Materials Stewardship Program under TSCA” (Concept Paper); and (2) “TSCA Inventory Status of Nanoscale Substances -- General Approach” (TSCA Inventory Paper). The third notice solicits public comments on specific aspects of the proposed information collection request (ICR) for the voluntary NMSP. According to EPA, the purpose of the August 2, 2007, public meeting, which will occur during the comment period on the draft documents, is to further discussion and development of the NMSP. Registration for the meeting will be open until July 30, 2007, but is not necessary to attend the meeting. Registration will be available through the NMSP website at http://www.epa.gov/oppt/nano. Requests to make oral comments at the meeting are due July 30, 2007.

Draft Documents

The TSCA Inventory Paper describes EPA’s current thinking regarding whether a nanoscale material is a “new” or “existing” chemical substance under TSCA. The Concept Paper describes EPA’s general approach, issues, and considerations for the NMSP, and is intended to serve as a starting point for continuing work with stakeholders on the detailed design of the NMSP. Comments will be due 60 days after EPA publishes the notice of availability in the Federal Register, which EPA expects to occur on July 12, 2007.

EPA states that it developed the concept paper to outline its initial thinking about the NMSP.  EPA will be working collaboratively with other federal agencies and stakeholders to further develop and implement the NMSP.  Although dependent on the outcome of this development process, EPA envisions that the components of the NMSP could include:

  • Assembling existing data and information from manufacturers and processors of existing chemical nanoscale materials;
  • Encouraging the development of test data needed to provide a firmer scientific foundation for future work and regulatory/policy decisions; and
  • Identifying and encouraging use of a basic set of risk management practices in developing and commercializing nanoscale materials.

The concept paper outlines proposed ideas for reporting on nanoscale materials in commerce, developing data on representative nanoscale materials, and identifying risk management practices.  According to EPA, it describes who may wish to participate, the reporting expectations for participants, what the program could entail, and what EPA intends to do with the data generated from the program.  It also describes the potential benefits of participation.

EPA will use the data from the NMSP to gain an understanding of which nanoscale materials are produced, in what quantities, how they are used, and the data that is available for such materials.  EPA scientists will use data collected through the NMSP, where appropriate, to aid in determining how and whether certain nanoscale materials or categories of nanoscale materials may present risks to human health and the environment.

While EPA is seeking comment on all aspects of the NMSP and the TSCA Inventory Paper, EPA states that it “is especially interested in comments on the following items”:

  1. Whether the data elements that have been identified in the NMSP are appropriate for nanoscale materials.
  2. Timing and phasing of submissions under the NMSP basic and in-depth programs and whether approaches for tiering data submissions are appropriate.
  3. Who would participate in NMSP and how to encourage participation, especially from small- and medium-sized enterprises.
  4. What criteria to use for the NMSP program evaluation and views on the timing and nature of any reports EPA may issue.
  5. How to engage industry and other stakeholders in the NMSP in-depth program and approaches for generating test data.
  6. The processes and roles for EPA, participants, and other stakeholders during development and evaluation of data for the in-depth program.
  7. Possible approaches for identification and use of alternative sources of data, to minimize the burden of information collection associated with the NMSP.
  8. Uses for the data submitted to EPA under the NMSP.
  9. Issues relevant to scope, definitions, and descriptions.
  10. The suitability of the approach for determining the TSCA Inventory status of nanoscale materials discussed in the TSCA Inventory Paper.
  11. Whether, in combination, the TSCA Inventory Paper and the NMSP Concept Paper are sufficiently clear in how EPA plans to address nanoscale materials that are new or existing chemicals under TSCA and the NMSP and, if needed, an indication of areas where further clarification may be warranted.

Draft ICR

The draft ICR covers the information collection-related activities related to NMSP and the estimated paperwork burdens associated with those activities. EPA is soliciting public comments on specific aspects of the proposed information collection for the voluntary NMSP.  Comments on the draft ICR are due 60 days after it is published in the Federal Register, which EPA expects to occur on July 12, 2007.

PEN Report Recommends TSCA Amendments

On May 23, 2007, the Woodrow Wilson International Center for Scholars Project on Emerging Nanotechnologies (PEN) released a report entitled EPA and Nanotechnology: Oversight for the 21st Century, which identifies actions that should be taken to establish an oversight system. The report focuses in particular on the U.S. Environmental Protection Agency (EPA), which it describes as “a key agency in any oversight effort because of its numerous regulatory authorities and its mission to protect the environment and human health.” According to the report, a review of existing EPA authorities reveals a number of weaknesses. In particular, the report states that the Toxic Substances Control Act (TSCA), “which is the only law potentially capable of providing general oversight for nanotechnology, is extremely deficient in many respects and needs to be amended.” Moving beyond TSCA, the report states further that “virtually every authority that EPA has at its disposal has weaknesses in terms of nanotechnology oversight.” The report discusses tools that will need to be combined in an oversight system, including information tools, voluntary efforts, economic tools, and liability. The report also discusses the role of state and local governments, and public participation, and outlines nine different examples of the ways the tools could be used. The report concludes with an action agenda containing more than 25 actions necessary to improve the oversight of nanotechnologies.

ED Will Hold Webcast on REACH, TSCA, and CEPA Best Practices

Environmental Defense (ED) will hold a webcast regarding its recent report, Not That Innocent: A Comparative Analysis of Canadian, European Union and United States Policies on Industrial Chemicals, on May 24, 2007, from 3:00 p.m. to 4:30 p.m. (EDT). The webcast will include a 45-minute presentation and a question and answer period. Dr. Richard Denison, Senior Scientist at ED, will present the findings and discuss his report, which compares the European Union’s new Registration, Evaluation, and Authorization of Chemicals (REACH) regulation, the Toxic Substances Control Act (TSCA), and the Canadian Environmental Protection Act (CEPA).

Best practices for and a comparison of how each of these policies addresses the following “core functions” will be presented:

  • Identify and prioritize chemicals of concern;
  • Track chemicals and their production and use;
  • Foster the generation and submission of risk-relevant information;
  • Assess information to determine hazard/exposure/risk;
  • Impose controls to mitigate risk; and
  • Share and disclose information while protecting confidential business information.

Implications of the findings for chemicals policy reform will also be discussed.

To participate, contact Cathy Malina by COB May 22, 2007. Details and a toll-free call-in number will then be forwarded prior to the call. In addition to a telephone line, Internet access is needed to view presentation materials. If this is not possible, please advise Ms. Malina so alternative arrangements can be made.
