T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationSanitary SewageMost of the airport facilities along the west side of the Airport, including the Airport terminal and belly cargo facilityare connected to the municipal sanitary sewer system along Post Road for treatment at the Warwick WastewaterTreatment Plant. Since the 2004 baseline assessment was conducted and the InterLink was opened in 2010, rental carfacilities are no longer located on the Airport. Sanitary waste from aircraft is pumped into lavatory trucks. Trucksoffload the waste at the triturator. The triturator is housed underground in an enclosed shed to minimize potentialstormwater contact with the sanitary waste. The waste is then gravity-fed into a holding tank. A pump stationconveys the waste to a sewer line connected to the municipal sewer system along Post Road.The majority of the Airport and tenant hangar facilities on the northern portion of the Airport have individualon-site septic disposal (ISDS) systems. The Airport and the individual tenants maintain these septic systems. In2010, RIAC installed a sewer line and pump station to serve Hangar No. 2. Waste from the Aircraft Rescue andFire Fighting (ARFF) Unit and the Airport Traffic Control Tower (ATCT) facilities are conveyed to the City ofWarwick sanitary sewer for treatment.Demolition DebrisHangar No. 1 is known to contain asbestos. Other buildings constructed prior to 1980 potentially includeasbestos-containing materials (ACM). Residential buildings constructed prior to 1978 and commercial orindustrial buildings constructed prior to the mid-1990s potentially contain lead-based paint building materials.Federal law now prohibits the widespread use of these materials, particularly in residential buildings. Due toless stringent regulations, commercial and industrial buildings are considered more likely than residentialbuildings to contain these materials.4.17 Light Emissions and Visual EnvironmentThis section describes the Baseline Condition for light emissions and the visual environment within the ProjectArea.4.17.1 MethodologyThe Baseline Conditions ambient light levels were assessed by inventorying the current lighting systemenvironment within the Project Area. The visual environment was subjectively characterized in regard to theexisting environment, architecture, historic or cultural setting, and land use planning.4.17.2 Affected EnvironmentThis section describes the Baseline Condition for lighting systems and visual environment the Airport.4.17.2.1 Lighting SystemsA variety of lighting systems are required by the FAA at airports that operate in all weather conditions. Thoselighting systems are designed to permit aircraft to operate safely and under all weather conditions, both dayand night.Chapter 4 – Affected Environment 4-83 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH04_Affected_Env_JUL_2011.doc
