Air, Noise, and Water Quality Monitoring Program, Airport Construction Site, Moen Island, Truk District, Trust Territory of the Pacific Islands, Part A, Pre-Construction

No abstract was published. A summary of the Introduction and Objectives follows.

The existing runway at the Truk International Airport on Moen Island will be lengthened and widened to provide capability for supporting existing and forecast air transportation requirements and for handling medium range jet aircraft without operating restrictions or safety hazards. The 5100-ft long runway will be repositioned approximately 150 ft northwest, so that the new runway centerline coincides with the northeast edge of the existing runway, and extended to 6000 ft long. The runway fill area will be extended 1400 ft southwest and 600 ft northeast. The runway extensions into the Truk Lagoon will consist of protective embankment and dredged coral fill. Basaltic rock obtained from the existing upland quarry near the northeast end of the existing runway will be used for the protective embankment. Approximately 2,100,000 cubic yds of dredged coral material will be used as fill for the airport extension.

This study of air, noise, and water quality prior to construction was requested by the U.S. Navy in accordance with Contract No. N62742-78-C-0029, Part A. It is a portion of the first part of a three-part environmental monitoring program which will consist of:

  1. Part A. Pre-Construction Monitoring Program
  2. Part B. Construction Monitoring Program
  3. Part C. Post- Construction Monitoring Program

Each of these parts is further divided into two portions: a water (and, for Part A, noise and air) quality monitoring program, and a biological monitoring program. The biological monitoring program is being undertaken by the Marine Laboratory of the University of Guam and is described in a separate report.

The objectives of this study were to:

  1. obtain (prior to construction) air, noise and/or water quality information for the airport, rock quarry and dredging/dragline sites; and
  2. develop turbidity limits to be used for controlling changes caused by construction activity.
