COMPTUEX/JTFEX EA/OEA Final Chapter 4emissions levels specified in the law. The South Coast Air Quality Management District (SCAQMD) hasnot yet developed and received approval for a SIP for the Federal 8-hour ozone standard or the FederalPM 2.5 standard. In accordance with the General Conformity Rule, as adopted by the SCAQMD inRegulation XIX, of which Rule 1901 applies to Federal Actions, the de minimis levels for ozoneprecursors (based on the current approved SIP), CO, PM 10 , and PM 2.5 and precursors are as follows:Ozone precursors (NO x and ROGs)COPM 1010 tons per year100 tons per year70 tons per yearPM 2.5 and precursors (NO x , SO x , NH 3 , ROGs) 100 tons per yearThe estimated emissions for COMPTUEX/JTFEX training events within 3 nm of shore within the SouthCoast Air Basin were estimated. The results are shown in Table 4.1-1.Because the number of COMPTUEX/JTFEX training events that would occur during a single year wouldnot increase, the net emissions associated with implementation of the Proposed Action in comparisonwith the No Action Alternative would be zero for all criteria pollutants. The Proposed Action does notrepresent an increase in emissions over the No Action Alternative, and net emissions are therefore belowthe de minimis thresholds for requiring a full conformity determination. Furthermore, emissions ofcriteria pollutants are within the emissions budget contained in the SCAQMD SIP for Navy activitieswithin 3 nm of shore.Table 4.1-1.

The provisions of the General Conformity Rule state that a Proposed Action isexempt from the requirements of a full conformity demonstration for those pollutants for which emissionsincreases are below the de minimis emissions levels specified in the law. The San Diego Air PollutionControl District (SDAPCD) has not yet developed and received approval for a SIP for the Federal 8-hourozone standard or the Federal PM 2.5 standard. In accordance with the General Conformity Rule, asadopted by the SDAPCD in Regulation XV, of which Rule 1501 applies to Federal Actions, the deminimis levels for ozone precursors (based on the current approved SIP), CO, and PM 10 are as follows:February 2007 4-4
