EPA has established a docket for this action under docket identification (ID) number EPA–HQ– OPP–2006–0351. Publicly available docket materials are available either in the electronic docket at http:// www.regulations.gov, or, if only available in hard copy, at the Office of Pesticide Programs (OPP) Regulatory Public Docket in Rm. S–4400, One Potomac Yard (South Building), 2777 S. Crystal Drive Arlington, VA. The hours of operation of this Docket Facility are from 8:30 a.m. to 4 p.m., Monday through Friday, excluding legal holidays. The Docket telephone number is (703) 305–5805. 2. Electronic access. You may access this Federal Register document electronically through the EPA Internet under the ‘‘Federal Register’’ listings at http://www.epa.gov/fedrgstr. II. What Guidance Does this PR Notice Provide? The EPA is concerned that sanitizer, disinfectant and other antimicrobial products are being used to treat surfaces of HVAC&R systems, including but not limited to use as a part of an air duct cleaning program. When initially registered, these products were approved for use on hard surfaces such as countertops, but air ducts were not intended to be included in the broad hard surface category. EPA is concerned that data demonstrating efficacy when used in air ducts have not been submitted for review by the Agency. Moreover, use of these products in HVAC&R systems such as air ducts pose potential human exposure and health risks to applicators and building occupants which have not been assessed by the Agency. This draft PR Notice provides guidance which, once final, the Agency would provide to registrants concerning labeling language that EPA believes would address its current concerns for sanitizer, disinfectant and other antimicrobial products whose labels bear directions for use on, or incorporation within, hard, non-porous surfaces, but which have not been specifically approved for use in PO 00000 Frm 00040 Fmt 4703 Sfmt 4703 HVAC&R systems. The PR Notice describes an Agency approach that registrants of products subject to this Notice should add a ‘‘Do Not Use’’ statement to the labeling of such products. Supporting documents for this draft PR Notice are contained in the docket. EPA originally published this document for comment in the Federal Register on September 22, 2006 (71 FR 55471). The public comment period ended on November 21, 2006. EPA received a request from The Chlorine Institute to extend the comment period. The Chlorine Institute has requested that the Agency provide additional information which was utilized in support of the draft guidance. They have requested additional time to evaluate this information. EPA agrees to reopen the comment period for an additional 60 days. III. Do PR Notices Contain Binding Requirements? The PR Notice discussed in this notice is intended to provide guidance to EPA personnel and decision makers and to pesticide registrants. While the requirements in the statutes and Agency regulations are binding on EPA and the applicants, this PR Notice is not binding on either EPA or pesticide registrants, and EPA may depart from the guidance where circumstances warrant and without prior notice. Likewise, pesticide registrants may assert that the guidance is not appropriate generally or not applicable to a specific pesticide or situation.

SUPPLEMENTARY INFORMATION: I. Information About the Document IRIS is a database that contains Agency scientific positions on potential adverse human health effects that may result from chronic (or lifetime) exposure to specific chemical substances found in the environment. The database (available on the Internet at http://www.epa.gov/iris) contains qualitative and quantitative health effects information for more than 500 chemical substances that may be used to support the first two steps (hazard identification and dose-response evaluation) of the risk assessment process. When supported by available data, the database provides oral reference doses (RfDs) and inhalation reference concentrations (RfCs) for chronic health effects, and oral slope factors and inhalation unit risks for carcinogenic effects. Combined with specific exposure information, government and private entities use IRIS to help characterize public health risks of chemical substances in a site-specific situation and thereby support risk management decisions designed to protect public health. 2,2,4-Trimethylpentane, also known as isooctane or isobutyltrimethylmethane, is a PO 00000 Frm 00041 Fmt 4703 Sfmt 4703 78435 hydrocarbon used primarily in deriving high-octane fuels. It comprises about 10% of unleaded gasoline. 2,2,4Trimethylpentane is released into the environment through the manufacture, use, and disposal of products associated with the gasoline and petroleum industry. The current assessment posted on IRIS (1991) does not include an evaluation of the oral non-cancer or the cancer literature; for the inhalation RfC, a message indicates that the health effects data for 2,2,4-trimethylpentane were considered inadequate for the derivation of an inhalation RfC. A review of the more recent literature identified mechanistic studies, gavage studies, and toxicokinetic studies, the majority of which were designed to specifically address and characterize the involvement of alpha2u-globulin accumulation in the renal toxicity observed in the male rat. Little or no evaluation of other endpoints in tissues/ organs other than the kidney was reported. Therefore, the major issues discussed in the draft assessment are: (1) the association of TMP-induced renal effects in male rats with alpha2uglobulin accumulation, and (2) the lack of studies with sufficient duration and dose-response information for any endpoint from which to derive reference values.

ACTION: Notice; request for public comment. AGENCY: SUMMARY: Notice is hereby given that a proposed Administrative Order on Consent (‘‘Agreement’’) concerning portions of the Fort Ord Superfund Site (‘‘Site’’) in Monterey, California has been negotiated by the United States Environmental Protection Agency (‘‘EPA’’), the California Department of Toxic Substances Control (‘‘DTSC’’) and the Fort Ord Reuse Authority (‘‘Respondent’’) subject to the final review and approval of the EPA, DTSC and the U.S. Department of Justice. The proposed Agreement concerns cleanup of portions of the Site pursuant to the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. 9604, 9606 and 9622 (‘‘CERCLA’’). Pursuant to a Federal Facilities Agreement (‘‘FFA’’), the U.S. Army (‘‘Army’’) is required to perform the CERCLA response actions for the Site; however, the FFA will be amended to suspend the obligations of the Army to conduct those response actions that will be undertaken by the Respondent pursuant to the Agreement. The Army is preparing a Finding of Suitability for Early Transfer (‘‘FOSET’’), which will be submitted to EPA Region 9, and the State of California for their approval after a public comment period. Upon approval of the FOSET, the Army will transfer portions of the Site to the Respondent. The Army and the Respondent will enter into an Environmental Services Cooperative Agreement, which will require the Respondent to perform certain CERCLA response actions on the transferred portions of the Site, using grant monies from the Army. The proposed Agreement would require the Respondent to prepare and perform removal actions, one or more remedial investigations and feasibility studies and one or more remedial designs and remedial actions for certain contaminants present on the transferred portions of the Site, under the oversight of EPA and the State of California. The proposed Agreement includes EPA and DTSC covenants not to sue or to take administrative action against the Respondent, provided that the PO 00000 Frm 00042 Fmt 4703 Sfmt 4703 Respondent complies with all the terms and conditions of the Agreement. The Agreement also commits the Respondent to reimburse direct and indirect future response costs incurred by EPA and DTSC in connection with actions conducted under CERCLA at the transferred portions of the Site. For thirty (30) calendar days following the date of publication of this notice, EPA will receive written comments relating to the proposed Agreement. EPA’s response to any comments received will be available for public inspection at the U.S. Environmental Protection Agency, 75 Hawthorne Street, San Francisco, CA 94105.
