). ABSTRACT IMMimuffKOOworsn 



The DAMOS (Disposal Area Monitoring System) Program has evolved a great deal over the past 15 years in the course of 

 monitoring nine regional and several project-specific disposal sites extending from western Long Island Sound to Maine. During the 

 past four years, scientists at NED and SAIC, along with a Technical Advisory Committee (TAC), have developed a tiered monitoring 

 protocol for the DAMOS Program to provide guidelines and a logical structure for the monitoring program, and to establish a system 

 of decision criteria based on program management objectives. 



This tiered monitoring protocol is a major advance from past monitoring programs, because it is based on the testing of null 

 hypotheses. The null hypotheses that serve as a foundation for the DAMOS tiered monitoring protocol help focus the field monitoring 

 program on critical issues for making management decisions. This eliminates the tendency for a "shotgun" approach to monitoring. 

 Each observation is required to answer a question, and each question ultimately leads to a management decision. 



The tiered monitoring/management program was designed to address compliance with permit regulations, model 

 verification to check the validity of predictions and assumptions underlying the tiered sampling design, and identification of long-term 

 trends in the environment that might be related to disposal activity. Separate tiered monitoring protocols have been developed for 

 both confined and unconfined dredged material mounds in open-water containment disposal sites. 



This is one of the first tiered programs developed for dredged material disposal site monitoring and, as such, it has evolved 

 through a process of periodic public review and has undergone substantial revision. The flow charts presented in this document are 

 not inflexible protocols, but instead provide a framework for NED's overall management and monitoring of the DAMOS disposal sites; 

 their application requires a degree of both common sense and best professional judgement. It is the intention of the DAMOS program 

 to continue to revisit the monitoring and management issues periodically to improve the program further as we gain a better 

 understanding of the environmental responses to dredged material disposal.
