T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluation5.7.5 Temporary Impacts from Short-Term Construction ActivitiesAir emissions would increase temporarily during the short-term construction activities associated withAlternatives B2 and B4. The air quality impact during construction would be a function of the number, types ofequipment, and operating hours.5.7.5.1 Alternative B2Annual construction phase and maximum construction-related emissions from Alternative B2 for the phases ofconstruction from 2015 and 2020 are provided in Table 5-87. During the 2015 phase of construction, 2013 isforecasted to have the highest total construction-related emissions for all pollutants analyzed due to the amountof construction equipment utilized for this time period. During the 2020 phase of construction, 2020 is expectedto have the highest total construction-related emissions for all pollutants (except for CO which would be 2018);due to the amount of construction equipment utilized for this timeframe. These values are well within theGeneral Conformity applicability thresholds for VOC and NO Xof 50 and 100 tons per year, respectively (seeSection 5.7.6, General and Transportation Conformity).Table 5-87Alternative B2: Construction Year and MaximumConstruction Emissions Inventory (tpy)Maximum AmountsPollutant 2015 Phase 1 2020 Phase 2CO 20.9 18.7VOC 3 4.4 3.8NOX 4 49.5 19.4SOX 0.2 0.1PM10 7.3 5.7PM2.5 2.7 1.3Construction YearPollutant 2012 2013 2014 2015 2016 2017 2018 2019 2020CO 3.1 20.9 13.2 9.7 3.6 15.6 18.7 7.7 13.8VOC 3 0.5 4.4 2.7 1.5 0.4 1.4 2.7 1.9 3.8NOX 4 6.1 49.5 27.6 14.8 3.0 10.0 17.1 10.5 19.4SOX
