# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Withdrawal of final rules.

# SUMMARY:

                        EPA is withdrawing two significant new use rules (SNURs) promulgated under section 5(a)(2) of the                               ( print page 42178)                            Toxic Substances Control Act (TSCA) for chemical substances which were the subject of premanufacture notices (PMNs), i.e., multi-walled carbon nanotubes (PMN P-08-177) and single-walled carbon nanotubes (PMN P-08-328). These chemical substances are subject to TSCA section 5(e) consent orders issued by EPA. EPA published the SNURs using direct final rulemaking procedures. EPA received a notice of intent to submit adverse comments on these rules. Therefore, the Agency is withdrawing these SNURs, as required under the expedited SNUR rulemaking process. EPA also intends to publish in the                         **Federal Register**                        , under separate notice and comment rulemaking procedures, proposed SNURS for these two chemical substances.                    

# DATES:

This final rule is effective August 21, 2009.

# SUPPLEMENTARY INFORMATION:

## I. Does this Action Apply to Me?

                    A list of potentially affected entities is provided in the                     **Federal Register**                     of June 24, 2009 (74 FR 29982) (FRL-8417-6). If you have questions regarding the applicability of this action to a particular entity, consult the technical person listed under                     **FOR FURTHER INFORMATION CONTACT**                    .                

## II. What Rules are Being Withdrawn?

                     In the                     **Federal Register**                     of June 24, 2009 (74 FR 29982), EPA issued several direct final SNURs, including SNURs for the two chemical substances that are the subject of this withdrawal. These direct final rules were issued pursuant to the procedures in 40 CFR part 721, subpart D. In accordance with 40 CFR 721.160(c)(3)(ii), EPA is withdrawing the rules issued for multi-walled carbon nanotubes (PMN P-08-177) and single-walled carbon nanotubes (PMN P-08-328) because the Agency received a notice of intent to submit adverse comments. EPA intends to propose SNURs for these two chemical substances via notice and comment rulemaking in a future                     **Federal Register**                     document.                

                     For further information regarding EPA’s expedited process for issuing SNURs, interested parties are directed to 40 CFR part 721, subpart D, and the**Federal Register**                     of July 27, 1989 (54 FR 31314). The record for the direct final SNURs for these chemical substances which are being withdrawn was established at EPA-HQ-OPPT-2008-0252. That record includes information considered by the Agency in developing these rules and the notice of intent to submit adverse comments.                

## III. How Do I Access the Docket?

                     To access the electronic docket, please go to                     *http://www.regulations.gov*                     and follow the online instructions to access docket ID no. EPA-HQ-OPPT-2008-0252. Additional information about the Docket Facility is provided under                     **ADDRESSES**                     in the                     **Federal Register**                     document of June 4, 2009 (74 FR 29982). If you have questions, consult the technical person listed under                     **FOR FURTHER INFORMATION CONTACT**                    .                

## IV. What Statutory and Executive Order Reviews Apply to this Action?

                     This final rule revokes or eliminates an existing regulatory requirement and does not contain any new or amended requirements. As such, the Agency has determined that this withdrawal will not have any adverse impacts, economic or otherwise. The statutory and executive order review requirements applicable to the direct final rule were discussed in the                     **Federal Register**                     document of June 24, 2009 (74 FR 29982). Those review requirements do not apply to this action because it is a withdrawal and does not contain any new or amended requirements.                

## V. Congressional Review Act

                    The Congressional Review Act, 5 U.S.C. 801*et seq*., generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report to each House of the Congress and the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the                     **Federal Register**                    . This rule is not a “major rule” as defined by 5 U.S.C. 804(2).
