Acquisition of suitable land for confined disposal of dredged material is becoming increasingly difficult. This problem could be minimized if the useful life of disposal areas could be extended, allowing reuse over longer periods. The concept of disposal site reuse involves the reduction in volume andor actual removal of dredged material from the disposal area for use elsewhere thereby allowing additional placement of dredged material at the site. Among the advantages to be realized through site reuse are 1 A permanent reusable site would be provided for the maintenance dredging at a centralized location 2 Operation of reusable sites would be environmentally compatible because facilities could be properly planned and engineered, greater control is possible, and site operation is better supervised 3 Valuable resources could be reclaimed from the dredging operation and donated or sold for productive use and 4 Expense and public objection to new disposal areas would be greatly reduced. For site reuse to be successful, the material must be in a usable condition, potential uses must be identified, and site management must be tailored to meet requirements for continued reuse. Research completed to date has identified methods of separating, drying, and rehandling dredged material, legal and policy constraints regarding marketing and disposition of the material, and potential use of dredged material for landfill and construction purposes.
