T.F. Green Airport Improvement Program - FEIS Chapters - PVD

T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationAlternatives B2 and B4 is the ability for T.F. Green Airport to handle longer haul flights. Aircraft fuelconsumption will increase due to the increased fuel requirements of long-haul flights. Flight times on approachor departure paths are not expected to change.Ground Service EquipmentFuture estimates of fuel consumption by GSE, GSV, and generators that use gasoline and diesel is shown inTable 5-130. Changes to the terminal and apron as part of the Improvement Program would not substantiallyincrease the number of on-Airport service vehicles or substantially alter the time needed for the existing servicefleet to arrive at gates. However, indirectly aircraft operations and load factors are projected to increase duringAlternatives B2 and B4, and No-Action Alternative, requiring more GSE or extended use of GSE vehicles whichwould cause an increase in fuel usage.Table 5-130 Future Estimated Annual Energy Consumption by Source Category and Alternative 12015 2020 2025Alternative Alternative Alternatives Alternatives B2Source No-Action B2 B4 No-Action B2 and B4 No-Action and B4Stationary FacilitiesElectricity 1 (kilowatts-hours per year) 15,537,300 15,537,300 15,537,300 15,537,300 33,398,100 15,537,300 33,398,100Natural Gas 2 (cubic feet per year) 17,055,000 17,055,000 17,055,000 17,055,000 20,931,100 17,055,000 20,931,100AircraftJet A (gallons) 3 36,205,500 36,205,500 57,064,100 38,766,300 59,337,400 41,182,900 61,639,700Av Gas (gallons) 126,700 126,700 138,600 135,700 146,600 144,200 155,000GSE/GSV/GeneratorsGasoline (gallons) 47,900 47,900 52,400 51,300 55,400 54,500 58,500Diesel (gallons) 99,700 99,700 109,100 106,800 115,300 113,500 121,900Note: A public access compressed natural gas station (CNG) opened in 2006. Average annual gallons dispensed are approximately 57,500 gallons which is not expectedto change as a result of the proposed airport enhancements.1 Future year electricity based on the following data: parking garage – 720,000 sq ft @ 1.5w/sq ft = 1080KW, Terminal expansion – 50,000 sq ft @ 12w sq ft = 600KW,Cargo building – 20,000 sq ft @ 1.5w/sq ft= 30KW and 10kw for additional airside electricity load for new lights, signs, and cable, multiplied by 24 hours, multiplied by365 days to be expressed in kWh/Yr. If the Runway 5-23 extension for Alternatives B2 or B4 would require additional gates, electricity consumption could go up to33,758,100 kWh/Yr by 2020.2 Future year usage of natural gas based on estimated energy needs for the terminal expansion. Natural gas usage is extremely variable and dependent on weather conditions.3 Future year fuel usage based on aircraft operations from the EIS Forecast which assumes additional long-haul flights. This assumes the average short-hauloperation is 600 nm, the average long-haul operation is 2,700 nm.Motor VehiclesMotor vehicle fuel consumption includes fuel use by motor vehicles on airport roadways, in parking facilities, andidling at terminal curbsides. The Improvement Program will not increase access time (the time it takes for motorvehicles to travel to and from the Airport) because on-Airport traffic patterns are not expected to change substantially.Fuel consumption by individual motor vehicles associated with accessing the Airport will not change substantially.Indirectly related to these enhancements, the quantity of passengers is projected to increase in Alternatives B2 and B4,and the No-Action Alternative, which would increase the overall quantity of vehicles, thereby increasing overall motorvehicle fuel consumption. This estimated increase would not adversely affect regional supplies of motor vehicle fuel inNew England. Roadway changes in the City of Warwick under Alternatives B2 and B4 are not expected to causechanges in fuel consumption when compared to the No-Action Alternative.Chapter 5 - Environmental Consequences 5-279 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
