EPA Proposes TSCA Inventory Reporting Modifications

In the Federal Register issue of 08/13/2010, the Environmental Protection Agency (EPA) released for public comment a proposed rule that would, if adopted, significantly change the TSCA Inventory Update Reporting (IUR).

The first part of the notice, "Supplementary Information", explains the proposed changes to 40 CFR Parts 704, 710, and 711. The text of the proposed rule follows the Supplementary Information.

In the Supplementary Information, EPA states that it is proposing modifications to the IUR

 to meet four primary goals:
    1. To tailor the information collected to better meet the Agency's
overall information needs.
    2. To increase its ability to effectively provide public access to
the information.
    3. To obtain new and updated information relating to potential
exposures to a subset of chemical substances listed on the TSCA
Inventory.
    4. To improve the usefulness of the information reported.
EPA believes that expanding the range of chemical substances for which
comprehensive information is to be reported and adjusting the specific
reported information, the method and

[[Page 49659]]

frequency of collecting the information, and CBI requirements will
accomplish these goals.

Reading the Supplemental Information reveals a fifth, unstated goal - the creation of uniform reporting standards that will provide EPA with the information it needs to "identify and take follow-up action on chemical substances that may pose potential risks to human health or the environment" in a more efficent and timely manner, cutting the amount of time EPA staff will need to spend reviewing submitted information, determining if EPA action is required and uploading the information to a publicly available databse.

Under the proposed rule, EPA would require information to be submitted via agency supplied web based application

EPA believes the proposed requirement to use e-IURweb to report
electronically would eliminate problems related to the scanning of
paper documents, incorrect chemical identities, and other errors
introduced by the submitter. These errors substantially delayed the
availability of the IUR information to both internal EPA programs, such
as the Existing Chemicals Program, and the public. . . . EPA believes the
required use of e-IURweb and CDX would reduce the reporting burden on
industry by reducing both the cost and the time required to review,
edit, and transmit data to the Agency.

The terms manufacture, manufacturer, and site  would be redefined:

with this proposal . . . manufacture would be defined . . . to mean "to manufacture, produce, or import for commercial purpose.

Also with this proposal, manufacturer would be defined . . . to mean "a person who manufactures a chemical substance. "

The term site

would be defined under the IUR
rule to mean ``a contiguous property unit. Property divided only by a
public right-of-way shall be considered one site. More than one plant
may be located on a single site.
    (a) For chemical substances manufactured under contract, i.e., by a
toll manufacturer, the site is the location where the chemical
substance is physically manufactured.
    (b) The site for an importer who imports a chemical substance
described in 40 CFR 711.5 is the U.S. site of the operating unit within
the person's organization that is directly responsible for importing
the chemical substance. The import site, in some cases, may be the
organization's headquarters in the United States. If there is no such
operating unit or headquarters in the United States, the site address
for the importer is the U.S. address of an agent acting on behalf of
the importer who is authorized to accept service of process for the
importer.
    (c) For portable manufacturing units sent out to different
locations from a single distribution center, the distribution center
shall be considered the site.''
 

The proposed rule would also modify the definitions of the terms "commercial use", consumer use" "reporting year" "submission period" and add a definition for the term "industrial function".

The method of determining if a manufacturer or importer is subject to IUR reporting would be changed:

EPA is proposing to modify the method used to determine whether a
person is subject to IUR reporting. The proposed method would be to
determine whether, for any calendar year since the last principal
reporting year, a chemical substance was manufactured (including
imported) at a site in production volumes of 25,000 lb. or greater. The
proposed method would be effective after the 2011 IUR submission
period.
 

EPA is proposing this change because of the mounting evidence that
many chemical substances, even larger volume chemical substances, often
experience wide fluctuations in manufacturing volume from year to year.
 

Chemical substances coverd by IUR reporting would be changed to exempt water, both naturally occuring and manufactured, fully exempt the polymers starch, dextrin, and maltodextrin, and making chemical substances subject to enforceable consent decrees ineligible for exemption.

Data to be reported would change as well. The company name to be reported would be the name of the parent company, including its Dunns & Bradstreet (DNB) number, the chemical name(s) supplied would be the name as listed on the TSCA Inventory, production volume of chemicals manufactured, exported and/or imported would be reported on one report rather than multiple reports. A check box, to indicate if a chemical substance is to be recycled, remanufactured, reprocessed, reused or reworked would be added.

Among other changes, EPA is proposing to revise and expand the list of industrial function categories and replace the NAICS codes with Industrial Sector Codes based on the European Union's "Guidance on information requirements and chemical safety assesment". The codes for consumer and commercial product categories would also be revised.

These lists of codes would be revised to bring them into harmony with existing codes used in Canada, to better facilitate the exchange of information between EPA and its Canadian counterpart and to serve as a model for Mexican agencies to develop an inventory of chemical substances.

Manufacturers and importers would be required to report the "total number of commercial workers likely to be exposed while using the reportable chemical substance(s):

iii. Number of commercial workers reasonably likely to be exposed.
EPA is proposing to require that submitters report the total number of
commercial workers, including those at sites not under the submitter's
control, that are reasonably likely to be exposed while using the
reportable chemical substance, with respect to each commercial use. The
approximate number of workers would be reported using the same
definitions and ranges used for manufacturing and industrial processing
and use workers required by 40 CFR 710.52(c)(3)(v) and (4)(i)(F)
(proposed 40 CFR 711.15(b)(3)(vii) and (4)(i)(F)), respectively. The
ranges are:

    Fewer than 10 workers.
    At least 10 but fewer than 25 workers.
    At least 25 but fewer than 50 workers.
    At least 50 but fewer than 100 workers.
    At least 100 but fewer than 500 workers.
    At least 500 but fewer than 1,000 workers.
    At least 1,000 but fewer than 10,000 workers.
    At least 10,000 workers.

    Information on the number of commercial workers reasonably likely
to be exposed to the reportable chemical substance would be used to
characterize the commercial population reasonably likely to be exposed
to the subject chemical substance. The population characterization is
important to the development of the overall exposure characterization.
 

Claims of "Confidential Business Information" - also known more commonly as "trade secrets" - would be required to be substantiated and claimed at the time the IUR is submitted and "should be limited only to those data elements the release of which would likely cause substantial harm to the business' competitive position. . . . EPA expects that reducing the number of CBI claims would increase the amount of information available to the public and improve the timeliness of its public availability". In a previous section, EPA noted that manufacturers would submit claims for CBI on information that was publicly available from other sources and thus was not CBI at all.

In Unit V of of the Supplemental Information, EPA requests comments on the proposed rule and various other topics, ranging from how best to use IUR data to take action on chemical substances that might pose "unreasonable risks" with particular emphasis on protecting children from exposure to harmful chemical substances to changing the reporting cycle, changes in how EPA should collect the information, and whether IUR reporting requirements should be changed to include processors as well as manufacturers and importers.

Comments must be submitted by October 12, 2010. The notice describes how comments need to be submitted. After receiving and reviewing the comments submitted, EPA hopes to publish a final rule in Spring 2011. As with any proposed rule submitted for public comment by any Federal agency, there may be a "Notice of Further Proposed Rulemaking" (NPRM) or the agency may also issue an interim rule before the final rule is published.

EPA has established a docket (EPA-HQ-OPPT-2009-0187) on www.regulations.gov  where documents referenced in the Supplemental Information and comments on the proposed rule may be found.

A shorter discussion of the proposed rule may also be found on the OMB Watch website.

EPA Reopens Comment Period for Proposed SNUR for MWCNT

In a notice published in the Federal register on July 28, 2010, the Environmental Protection Agency (EPA) announced that it was adding new information to its public docket EPA-HQ-OPPT-2009-0686 and was reopening the comment period for  a proposed Significant New Use Rule (SNUR) for multiwalled carbon nanotubes (MWCNTS) first published in the Federal Register on February 3, 2010.

The proposed rule requires "persons who intend to manufacture, import, or process the substance" - described elsewhere in the notice as "multi-walled carbon nanotubes(generic)" to "be used as an additive/filler for polymer composites and support media for industrial catalysts" - "for an activity that is designated as a significant new use by this proposed rule to notify EPA at least 90 days before commencing that activity". This would give EPA time to assess "risks that may be presented by the intended uses and, if appropriate, to regulate the proposed use before it occurs."

Information regarding submission of comments will be found in the original notice of February 3, 2010.

The "Significant New Use" for the MWCNTS (generic) are described in the Feb. 3, 2010 notice as

certain changes from the use scenario described in the
PMN could result in increased exposures, thereby constituting a
``significant new use.'' EPA has determined that activities proposed as
a ``significant new use'' satisfy the two requirements stipulated in
Sec.  721.170(c)(2), i.e., these significant new use activities, ``(i)
are different from those described in the premanufacture notice for the
substance, including any amendments, deletions, and additions of
activities to the premanufacture notice, and (ii) may be accompanied by
changes in exposure or release levels that are significant in relation
to the health or environmental concerns identified'' for the PMN
substance.
 

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 Sec.  721.170(b)(3)(ii).
 

Following the closing of the comment period and review of the comments received, EPA will publish summaries and EPA's replied to the submitted comments in a future issue of the Federal register, along with the final rule.

EPA Proposes Significant New Use Rules for Single and Multi Walled Carbon Nanotubes

On Friday, 11/06, 2009, the Environmental Protection Agency (EPA) published a "Proposed Significant New Use Rules on Certain Chemical Substances" in the Federal Register (74 FR 57430). The "certain chemical substances" that the new use rules would affect are multi-walled carbon nanotubes and single-walled carbon nanotubes. This would amend 40 CFR Pt. 721 by adding Pts 721.1055 and 721.1056. The text of these new parts can be found at the end of this entry.

The  proposed SNURs on these substances are based on and consistent with the
provisions in the underlying consent orders. The proposed SNURs
designate as a ``significant new use'' the absence of the protective
measures required in the corresponding consent orders. This action
would require persons who intend to manufacture, import, or process
either of these two substances for an activity that is designated as a
significant new use by this 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.

 

Information on submitting comments may be found in the link to the proposed rule. Comments must be filed on or by December 7, 2009.

The EPA had issued a direct final rule  regarding SWCNs and MWCNs in the Federal Register of June 24, 2009 (74 FR 29982), but this was withdrawn after EPA received notice that adverse comments were going to be filed.

As explained in the notice, based on test data, the EPA has concluded that SWCNs and MWCNs pose risks to human health, particularly the lungs. To reduce that risk, EPA would require that workers exposed to carbon nanotubes wear an NIOSH approved full face respirator and protective clothing. Any purposeful disposal of these substances into US waters or waterways would be illegal under the proposed rules. The proposed rule would be applicable to manufacturers, importers and processors.

The record for the proposed SNURs may be found on Regulations.gov as docket EPA-HQ-OPPT-2008-0252.
