Environmental Protection Agency (EPA).
On October 18, 2006, EPA invited stakeholders to participate in the design, development, and implementation of a Nanoscale Materials Stewardship Program (NMSP) under the Toxic Substances Control Act (TSCA). NMSP is a voluntary program intended to complement and support EPA’s new and existing chemical programs under TSCA and will help provide a firmer scientific foundation for regulatory decisions by encouraging the development of key scientific information and appropriate risk management practices for nanoscale chemical substances (“nanoscale materials”). As part of this process, EPA is announcing the availability of two draft documents for public review and comment: “TSCA Inventory Status of Nanoscale Substances—General Approach” and “Concept Paper for the Nanoscale Materials Stewardship Program under TSCA.” The first document describes EPA’s current thinking regarding whether a nanoscale material is a “new” or “existing” chemical substance under TSCA. The second document describes the Agency’s general approach, issues, and considerations for NMSP and is intended to serve as a starting point for continuing work with stakeholders on the detailed design of NMSP.

A. What is the Applicable Legal Authority?
NMSP is a voluntary program intended to complement and support EPA’s new and existing chemical programs under TSCA. TSCA provides EPA authority to assure that new and existing chemical substances are manufactured, processed, used, and disposed of in a manner that protects against unreasonable risks to human health and the environment. TSCA applies to “chemical substances.” Nanoscale materials which meet the TSCA definition of “chemical substances” are subject to TSCA.
B. What Action is the Agency Taking?
EPA is announcing the availability of two documents for public review and comment. One document, entitled “TSCA Inventory Status of Nanoscale Substances—General Approach,” (“TSCA Inventory paper”) describes EPA’s general approach to determining whether a nanoscale material is a “new” or “existing” chemical substance under TSCA. The other document, entitled “Concept Paper for the Nanoscale Materials Stewardship Program under the TSCA,” is a concept paper describing a general approach, issues, and considerations for NMSP.
In a separate notice in this Federal Register, EPA is also issuing the draft Information Collection Request (ICR) covering the information collection related activities related to NMSP and the estimated paperwork burdens associated with those activities. Under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., an agency may not conduct or sponsor, and a person is not required to respond to, a collection of information, unless it displays a currently valid control number issued by the Office of Management and Budget (OMB). PRA also applies to voluntarily submitted information. Before submitting an ICR to OMB for review and approval, the agency must first solicit comment on the draft ICR. The draft ICR covering the potential information collection activities related to NMSP is also being made available for public review and comment.
C. Why is EPA taking this Action?
There is a growing class of materials commonly referred to as engineered nanoscale materials. Materials having structures with dimensions in the nanoscale (approximately 1-100 nanometers (nm)), also known as nanoscale materials or nanoscale substances, may have organizations and properties different than the same chemical substances with structures at a larger scale.
Nanoscale materials that meet the TSCA section 3(2)(A) definition of “chemical substance” are subject to TSCA. TSCA provides EPA with a strong framework for ensuring that new and existing chemical substances are manufactured and used in a manner that protects human health and the environment. TSCA distinguishes between “new” and “existing” chemical substances. Existing chemicals are those substances contained on the TSCA Inventory. New chemicals are those substances not contained on the TSCA Inventory. Under section 5 of TSCA, EPA requires manufacturers of nanoscale materials that are new chemicals, to notify the Agency 90 days prior to manufacture. The draft paper, “TSCA Inventory Status of Nanoscale,” is intended to explain the Agency’s current thinking on this question of “new” versus “existing” within the context of nanoscale materials.
On October 18, 2006, EPA launched a collaborative process and invited stakeholders to participate in the design, development, and implementation of a NMSP under TSCA. EPA is developing NMSP to complement and support its new and existing chemical efforts on nanoscale materials. As outlined in the “Concept Paper for the NMSP under TSCA,” the program is envisioned primarily for manufacturers of nanoscale materials that would be considered existing chemical substances under TSCA (though persons at a variety of stages of product development are also encouraged to participate). Manufacturers of existing chemical substances are not required to submit pre-manufacture notices to EPA under section 5 of TSCA. NMSP will also help provide a firmer scientific foundation for regulatory decisions by encouraging the development of key scientific information and appropriate risk management practices for nanoscale chemical substances (“nanoscale materials”).
EPA developed the concept paper to outline its initial thinking about NMSP. The Agency will be working collaboratively with other Federal agencies and stakeholders to further develop and implement NMSP. Although dependent on the outcome of this development process, the Agency envisions that the components of the program could include:Start Printed Page 38085
- 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.
- 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. 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 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 this program, 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.
This release of the two draft documents for public review and comment are an important part of the collaborative development process for NMSP. These draft documents are intended to further discussion about NMSP and will serve as the foundation for establishing the details of NMSP.
The Agency also intends to conduct a public meeting to obtain further public comment on these documents and any other issues pertaining to a NMSP and will announce that meeting date in a separate Federal Register notice. EPA will consider all comments and announce the availability in the Federal Register of the final versions of the ICR, TSCA Inventory paper and a document that describes NMSP. Once the details of NMSP have been announced, EPA will implement NMSP.
III. Request for Comments
While EPA is seeking comment on all aspects of NMSP and the TSCA Inventory paper, the Agency is especially interested in comments on the following items:
1. Whether the data elements that have been identified in 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 NMSP program evaluation and views on the timing and nature of any reports the Agency 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, in order to minimize the burden of information collection associated with NMSP.
8. Uses for the data submitted to EPA under the NMSP program.
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 referenced in Unit II.C.
11. Whether, in combination, the TSCA Inventory paper and the NMSP concept paper are sufficiently clear in how EPA plans at this time 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.
IV. Summary of Next Steps
As indicated previously, EPA intends to use a collaborative process that involves stakeholders in the design, development, and implementation of NMSP.
