Environmental Assessment for Replacement of Taxiway Sierra, Taxiway Whiskey, Pad 12, and Pad 13 at Joint Base Andrews-Naval Air Facility Washington, Prince George's County, Maryland.

摘要

JBA proposes to improve its operational efficiency by replacing Taxiways Sierra and Whiskey and Pads 12 and 13 on the airfield. The task for Taxiway Sierra would include demolishing and replacing approximately 49,500 square yards (10 acres) of existing pavements and shoulders and improving or replacing the taxiway's drainage, signage, and lighting systems. The task for Taxiway Whiskey would include replacing approximately 208,100 square yards (43 acres) of existing pavements and shoulders and improving or replacing the taxiway's drainage, signage, and lighting systems. Taxiway Sierra would be replaced before work on Taxiway Whiskey began. The area of Pad 12 is approximately 7,340 square yards (1.5 acres), and the area of Pad 13 is approximately 7,280 square yards (1.5 acres). The pavement on both pads is about 10 inches thick. Replacing the pads would include excavation, site preparation, striping, restoration of disturbed areas, and all necessary and essential utilities work to satisfy JBA operational requirements. Pads 12 and 13 would be replaced after work on Taxiway Whiskey was completed. This environmental assessment (EA) has been prepared to address the potential impacts of undertaking the abovementioned project. This EA has been prepared to report an evaluation of the proposed action and alternatives, including the No Action Alternative. Resource areas addressed in the EA are noise, air quality, safety and occupational health, earth resources, water resources, infrastructure/utilities, transportation, hazardous materials and wastes, biological resources, cultural resources, historic and archaeological resources, socioeconomics (including environmental justice and protection of children), land use and visual resources, and sustainability and greening. The Draft EA was made available to agencies and the public for a 30-day comment period from March 7, 2013, to April 7, 2013.
