T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluation5.7.5.2 Alternative B4Annual construction phase and maximum construction-related emissions associated with Alternative B4for the 2010 and 2020 construction phases are provided in Table 5-88. During the 2015 phase ofconstruction, 2014 is forecasted to have the highest total construction-related emissions for all pollutantsanalyzed due to the amount of construction equipment utilized in this time period. During the 2020phase of construction, 2016 is expected to have the highest total construction related emissions for allpollutants; due to the amount of construction equipment deployed in this timeframe. These values arewell within the General Conformity applicability thresholds for VOC and NO Xof 50 and 100 tons peryear, respectively (see Section 5.7.6, General and Transportation Conformity).Table 5-88Alternative B4: Maximum Construction Emissions Inventory (tpy)Maximum AmountsPollutant 2015 Phase 1 2020 Phase 2CO 18.9 17.8VOC 4 3.8 3.9NOX 5 38.3 31.6SOX 0.1 0.1PM10 6.8 6.4PM2.5 2.3 1.9Construction YearPollutant 2013 2014 2015 2016 2017 2018 2019 2020CO 4.0 18.9 18.6 17.8 15.5 16.8 9.3 10.0VOC 3 0.6 3.8 3.3 3.9 2.5 2.6 1.3 2.3NOX 4 6.6 38.3 32.5 31.6 18.0 16.6 7.4 12.1SOX 0.0 0.1 0.1 0.1 0.1 0.1 0.0 0.1PM10 5.1 6.8 6.5 6.4 5.7 5.6 5.1 5.3PM2.5 0.8 2.3 2.1 1.9 1.3 1.2 0.8 1.0Source: KB Environmental Services, Inc., 2011.Note: See Table 5-75 for explanatory abbreviations.tpy tons per year.1 The results shown are for the year 2012; the year of greatest emissions in the 2015 timeframe.2 The results shown are for the year 2016; the year of greatest emissions in the 2020 timeframe.3 General Conformity de minimis threshold for VOC is 50 tons/year.4 General Conformity de minimis threshold for NOx is 100 tons/year.Chapter 5 - Environmental Consequences 5-164 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
