T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluationin the 2002 T.F. Green Airport Master Plan Update, a separate analysis was conducted with the 2004 EIS Forecast 86 andhas been updated to reflect the 2010 FEIS No-Action and Build Alternatives Forecast demand levels, as shown inTable 2-10. The analysis indicates that there was an existing shortfall of approximately 128,000 gallons in the Airport’sthree-day Jet A fuel storage capacity in 2004. Although anticipated commercial service aircraft operations activity hasdeclined recently, as reflected in the latest EIS forecast revisions, up to 110,000 gallons of additional capacity by 2020 andup to approximately 135,000 gallons of additional capacity are needed by 2025.Table 2-9GSE Maintenance Building Requirements– 2010 FEIS No-Action Alternative and BuildAlternative Forecasts2010 FEIS No-Action Forecast Total Motorized Maintenance Building Requirements Surplus (Deficit)Year Cumulative GSE Growth Rate 1 GSE Units Bays 2 Square Feet 3 Bays Square Feet2004 4 — 70 9 15,700 0 (800)2015 (15.5)% 60 8 13,925 1 9752020 10.3% 67 9 15,656 0 (756)2025 12.6% 76 10 17,425 (1) (2,525)FEIS Build Alternative Forecast Total Motorized Maintenance Building Requirements Surplus (Deficit)Year Cumulative GSE Growth Rate 1,5 GSE Units Bays 2 Square Feet 3 Bays Square Feet2004 4 — 70 9 15,700 0 (800)2015 (0.6)% 70 9 15,700 0 (800)2020 10.1% 77 9 15,844 0 (944)2025 11.1% 86 10 17,613 (1) (2,713)Sources: T.F.

This analysis assumes that each bay would accommodate 8.25GSE units on average, which is consistent with the 2002 T.F. Green Airport Master Plan Update.3 Square footage requirements based on 1,280 square feet per bay for bay and support space, added to 15 square feet per GSE unit for storage, plus a 25 percent gross-up factor,which includes some inefficiency in dividing up space among tenants.4 A total of 9 bays and 14,900 square feet were available in 2004.5 Forecast includes 2010 FEIS No-Action Alternative Forecast and Incremental Build Alternative Forecast. The extension to Runway 5-23 for Alternative B4 would beimplemented by 2015. Alternative B2, including extending Runway 5-23, would be implemented by 2020. The facility requirements analysis provided in this chapteronly considers the 2015 implementation of the Build Alternatives (see Table 2-2).86 Existing and Future Fuel Demand and Fuel Farm Storage Capacity Expansion Analysis, T.F.
