Appendix C C-1

The air quality analysis examined impacts from air emissions associated with the proposed action. As part of the analysis, emissions generated from construction, aircraft operation, aerospace ground equipment (AGE), motor vehicles, and other area (nonmobile) sources were examined for carbon monoxide (CO), nitrogen oxides (NOX), sulfur dioxide (SOX), volatile organic compounds (VOCs), and particulate matter (PM10). Kern County Air Pollution Control District (APCD) is in serious nonattainment for ozone; Mojave Desert (AQMD) and Antelope Valley APCD are currently in severe nonattainment for ozone and moderate nonattainment for PM10 (See Table 3.5-4). The Feather River AQMD is a maintenance areas for ozone, and the air quality control region associated with Wright-Patterson AFB and is also a maintenance area for ozone. De minimis levels for the associated criteria pollutants are presented in Tables 3.5-2 and 3.5-3. CONSTRUCTION EMISSIONS: Construction activities would generate both combustive emissions from heavy equipment use and fugitive dust from ground-disturbing activities. Fugitive dust would be generated during construction activities associated with building construction and modification. These emissions would be greatest during site clearing and grading activities. Particulate matter emissions from ground-disturbing activities were computed are a rate of 220 lbs per acre per month (EPA 1995a) wit
