Hearing Before House MM&F-OGM&OCS on 30 March 1993 



Ocean Disposal of Contaminated Dredge Material 



Question from Mr. Green - What is considered "clean" dredge 

 material? 



ANSWER Dr. Engler: "Clean" dredged material refers to those 

 sediments that do not demonstrate an unacceptable adverse impact 

 on human health or the environment due to the presence of 

 contaminants when the material is dredged and disposed. "Clean" 

 dredged material may contain trace amounts of chemicals and other 

 materials that do not violate EPA and other federal and state 

 criteria for human and environmental impact for open water 

 disposal.
