Eight months after EPA's interim report on industry participation (or lack thereof) in its Nanoscale Materials Stewardship Program, EPA's Toxic Substances Control Act's ("TSCA") Interagency Testing Committee ("ITC") published a report in today's Federal Register mentioning that EPA intends to issue a new mandatory data collection rule for nanoscale materials under TSCA Section 8(a):

"EPA intends to develop a proposed TSCA section 8(a) rule to obtain information on the production, uses, and exposures of existing nanoscale materials.  EPA has indicated that it will ensure that the chemicals where there is ITC interest as described in this unit are either included in that action or are otherwise new chemical substances subject to premanufacture notifications (PMN) reporting under TSCA.  EPA also intends to develop a proposed TSCA section 4 rule to develop needed environmental, health, and safety data."

Among other things, TSCA section 8(a) allows EPA to issue a rule requiring the mandatory submission of data regarding:

(A) The common or trade name, the chemical identity, and the
molecular structure of each chemical substance or mixture for which
such a report is required.

(B) The categories or proposed categories of use of each such
substance or mixture.

(C) The total amount of each such substance and mixture
manufactured or processed, reasonable estimates of the total amount
to be manufactured or processed, the amount manufactured or
processed for each of its categories of use, and reasonable
estimates of the amount to be manufactured or processed for each of
its categories of use or proposed categories of use.

(D) A description of the byproducts resulting from the
manufacture, processing, use, or disposal of each such substance or
mixture.

(E) All existing data concerning the environmental and health
effects of such substance or mixture.

(F) The number of individuals exposed, and reasonable estimates
of the number who will be exposed, to such substance or mixture in
their places of employment and the duration of such exposure.

(G) . . . the manner or method of its disposal, and in any
subsequent report on such substance or mixture, any change in such
manner or method.
 

Some of the nanoscale materials prompting ITC's interest appear to be: fullerenes; titanium oxide nanowires; titanium oxide nanoparticles; nano zinc oxide; nanosilver; silica; quartz; cerium oxide; indium tin oxide; dendrimers; single-walled carbon nanotubes; multi-walled carbon nanotubes; carbon nanofibers; Se and Cd quantum dots; nanoceramic particles; and nanoclays.

In the June 24, 2009 federal register, the U.S. Environmental Protection Agency (EPA) issued two proposed Significant New Use Rules (SNUR) under Section 5(a) of the Toxic Substances Control Act (TSCA) for multi-walled and single walled carbon nanotubes.  The SNURs followed up on the EPA's prior September 2008 consent orders entered into with Thomas Swan & Co. Ltd. (Swan) for two of its Elicarb carbon nanotube products.

Under TSCA, the prior September 2008 consent orders were only binding on Swan.  "Consequently, after signing a Section 5(e) Consent Order, EPA generally promulgates a Significant New Use Rule (SNUR) that mimics the Consent Order to bind all other manufacturers and processors to the terms and conditions contained in the Consent Order.  The SNUR requires that manufacturers, importers and processors of certain substances notify EPA at least 90 days before beginning any activity that EPA has designated as a "significant new use. These new use designations are typically those activities prohibited by the Section 5(e) Consent Order."

Under the terms of the Septmeber 2008 consent orders which are incorporated into the new proposed SNURs, significant new uses of multi-walled and singled-walled carbon nanotubes are deemed to occur when employees do not “use gloves impervious to nanoscale particles and chemical protective clothing;” and/or fail to “use a NIOSH-approved full-face respirator with an N-100 cartridge while exposed by inhalation in the work area.”

Thus, the new proposed SNURs require these same conditions.

Manufacturers should also be aware that the EPA considers carbon nanotubes new chemical substances requiring full PMN notice, registration, and approval under Section 5 of TSCA, and has initiated at least one recent enforcement action against a carbon nanotube manufacturer who has failed to properly register its products.
