III. Summary of Public Comments Received and Agency Response to Comments

During the public comment period provided, EPA received no comments in response to the September 10, 2010 Federal Register notice (75 FR 55327) announcing the Agency’s receipt of the request to voluntarily amend registrations to terminate certain uses of products listed in Table 1.

IV. Cancellation Order

Pursuant to FIFRA section 6(f), EPA hereby approves the requested amendment to terminate uses of tetrahydro-3, 5-dimethyl-2 H -1,3,4- thiadiazine-2-thione registrations identified in Table 1 of Unit II anddelete uses of tetrahydro-3, 5-dimethyl2 H -1,3,4-thiadiazine-2-thione registrations identified in Table 2 of Unit II. Accordingly, the Agency orders that the product registrations identified in Table 1 of Unit II are hereby amended to terminate the affected uses, also listed in Table 1. Any distribution, sale, or use of existing stocks of the products identified in Table 1 of Unit II. in a manner inconsistent with any of the Provisions for Disposition of Existing Stocks set forth in Unit VI. will be considered a violation of FIFRA. V. What is the agency’s authority for taking this action?

Section 6(f)(1) of FIFRA provides that a registrant of a pesticide product may at any time request that any of its pesticide registrations be canceled or amended to terminate one or more uses. FIFRA, further provides that, before acting on the request, EPA must publish a notice of receipt of any such request in the Federal Register . Thereafter, following the public comment period, the Administrator may approve such a request. VI. Provisions for disposition of existing stocks

Existing stocks are those stocks of registered pesticide products which are currently in the United States and which were packaged, labeled, and released for shipment prior to the effective date of the action. The existing stocks provision for the products subject to this order is as follows.

Once EPA has approved product labels reflecting the requested amendments to delete uses, registrants will be permitted to sell or distribute products under the previously approved labeling for a period of 18 months after the date of Federal Register publication of the cancellation order, unless other restrictions have been imposed. Thereafter, registrants will be prohibited from selling or distributing the products whose labels include the deleted uses identified in Table 1 of Unit II., except for export consistent with FIFRA section 17 or for proper disposal.

Persons other than the registrant may sell, distribute, or use existing stocks of products whose labels include the deleted uses until supplies are exhausted, provided that such sale, distribution, or use is consistent with the terms of the previously approved labeling on, or that accompanied, products bearing the deleted uses.

**Official Release of the MOVES2010a and EMFAC2007 Motor Vehicle**  **Emissions Models for Transportation Conformity Hot-Spot Analyses and**  **Availability of Modeling Guidance**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Notice of Availability.

**SUMMARY :**  This Notice announces the availability of two new EPA guidance documents for: completing quantitative particulate matter (PM 2.5 and PM 10 ) hotspot analyses using EPA’s Motor Vehicle Emissions Simulator model (MOVES), California’s EMission FACtor model (EMFAC), and other models, and completing project-level carbon monoxide (CO) analyses using MOVES. These guidance documents will assist practitioners with implementing MOVES, EMFAC, air quality models, and applicable requirements.

EPA is approving the latest version of the MOVES model (MOVES2010a) for official use for quantitative CO, PM 2.5, and PM 10 hot-spot analyses outside of California. This notice also announces a two-year grace period before the MOVES2010a emissions model is required to be used in quantitative COand PM hot-spot analyses for projectlevel conformity determinations outside California.

EPA is also approving the latest version of the EMFAC model(EMFAC2007) for quantitative PM hotspot analyses for transportation conformity purposes within California. 1 This notice announces a two-year grace period before EMFAC2007 is required to be used for quantitative PM hot-spot analyses for project-level conformity determinations in California. While EPA is approving the MOVES2010a andEMFAC2007 models today for projectlevel transportation conformity purposes, this notice is applicable to current and future versions of the MOVES and EMFAC models, unless EPA notes otherwise when approving the models for conformity purposes.

**DATES :**  EPA’s approval of the MOVES2010a and EMFAC2007 emissions models is effective December 20, 2010. Today’s approval also starts a two-year transportation conformity grace period that ends on December 20, 2012, after which:

• MOVES2010a (outside of California) is required to be used for new quantitative CO, PM 10 , and PM 2.5 hot-spot analyses for transportation conformity purposes; and

• EMFAC2007 (within California) is required to be used for new PM 10 and PM 2.5 hot-spot analyses for transportation conformity purposes. These models can also be used during the grace period, as described further in this notice.

**FOR FURTHER INFORMATION CONTACT :**  For questions regarding the official release of MOVES2010a for quantitative CO, PM 2.5 , and PM 10 hot-spot analyses, contact Meg Patulski at patulski.meg@epa.gov, (734) 214–4842, Transportation and Regional Programs Division, Office of Transportation and Air Quality, EPA, 2000 Traverwood Road, Ann Arbor, MI 48105. For questions regarding the official release of EMFAC2007 for quantitative PM 2.5 and PM 10 hot-spot analyses in California, contact Karina O’Connor at oconnor.karina@epa.gov, (775) 833– 1276, Air Planning Office (AIR–2), Air Division, EPA, Region 9, 75 Hawthorne Street, San Francisco, CA, 94105–3901. Technical questions about completing emissions and air quality modeling for CO and PM hot-spot analyses can also be sent to conformity-hotspot@epa.gov.

**SUPPLEMENTARY INFORMATION :** 

The contents of this notice are as follows: I. Background II. Using MOVES at the Project Level III. Using EMFAC at the Project Level IV. Availability of Modeling Guidance I. Background A. What is transportation conformity?

Transportation conformity is a Clean Air Act (CAA) requirement to ensure that Federally supported highway and transit activities are consistent with ( ‘‘ conform to ’’ ) the State air quality implementation plan (SIP). Conformity to a SIP means that a transportation activity will not cause or contribute to new air quality violations, worsen existing violations, or delay timely attainment of the national ambient air quality standards (NAAQS) or any interim milestone. EPA’s transportation conformity regulations (40 CFR Parts 51.390 and 93) describe how Federally funded and approved highway and transit projects meet these statutory requirements. B. Hot-Spot Analyses

A hot-spot analysis in the context of transportation conformity is defined at 40 CFR 93.101 as an estimation of likely future localized pollutant concentrations and a comparison of those concentrations to the relevant
