EPA is printing a summary of a pesticide petition received under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, proposing the establishment of regulations in 40 CFR part 180.503 for residues of cymoxanil in or on caneberry. EPA has determined that this pesticide petition contains data or information regarding the elements set forth in FFDCA section 408(d)(2); however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the pesticide petition. Additional data may be needed before EPA rules on this pesticide petition. Pursuant to 40 CFR 180.7(f), a summary of the petition included in this notice, prepared by the petitioner along with a description of the analytical method available for the detection and measurement of cymoxanil residues is available on EPA’s Electronic Docket at https://www.regulations.gov/. To locate this information on the home page of EPA’s Electronic Docket, select ‘‘Quick Search’’ and type the OPP docket ID number. Once the search has located the docket, clicking on the ‘‘Docket ID’’ will bring up a list of all documents in the docket for the pesticide including the petition summary. VerDate Aug<31>2005 15:00 Nov 14, 2006 Jkt 211001 New Tolerance PP 6E7100. Interregional Research Project Number 4 (IR-4), 500 College Road East, Suite 201 West, Princeton, NJ 08540, proposes to establish a tolerance for residues of the fungicide, cymoxanil, 2-cyano-N-[(ethylamino)carbonyl]-2(methoxyimino) acetamide in or on caneberry at 4.0 parts per million (ppm). An analytical enforcement method is available for determining these plant residues by high performance level chromatography (HPLC) with ultraviolet (UV) detection. The limit of quantitation allows monitoring of crops with cymoxanil residues at or above the levels proposed in these tolerances.

Manufacturer Guidance Certification Procedure for Light-Duty Diesel Vehicles Using Selective Catalyst Reduction (SCR) Technologies Dated: November 6, 2006. Margo Tsirigotis Oge, Director, Office of Transportation and Air Quality. [FR Doc. E6–19264 Filed 11–14–06; 8:45 am] A. Background On February 10, 2000, EPA published the Tier 2 emission standards for lightduty vehicles and trucks. These standards established common, ‘‘fuel neutral’’ emission requirements for gasoline and diesel vehicles. They also set common standards for all passenger cars, light trucks, and medium-duty passenger vehicles. The Tier 2 standards allow emission averaging and require new vehicles to meet an average NOX emission level of 0.07 grams per mile (g/ mi). On January 18, 2001, EPA published a rule setting stringent new requirements for heavy-duty highway engines and vehicles starting in 2007. Manufacturers plan to meet these requirements by optimizing engine designs for low emissions and adding high-efficiency aftertreatment. The diesel engine NOX standard, which is phased-in between model years 2007 and 2010, is 0.20 grams per brake horsepower-hour (g/bhp-hr). Diesel engine and vehicle manufacturers have examined the use of several different types of NOX reduction technologies in order to meet these requirements. One type of NOX reducing technology, selective catalyst reduction (SCR), is of particular interest to diesel manufacturers because it can achieve as high as 90% NOX conversion efficiencies. An SCR system uses a nitrogen containing reducing agent (usually ammonia or urea) injected into the exhaust gas upstream of the catalyst. The reducing agent needs to be periodically replenished. Without the reducing agent, the efficiency of the SCR catalyst drops to zero and NOX emissions can potentially increase substantially. EPA intends to issue guidance to vehicle and engine manufacturers to discuss our intended approach for the certification of light-duty diesel vehicles and heavy-duty engines using SCR systems.
