Dredged Materials

Dredged materials subject to the requirement of a CWA permit are not considered hazardous wastes under RCRA. 

There are two major areas of overlap between MPRSA and RCRA. MPRSA prevents waste from an RCRA generator or TSDF from being deposited into the ocean, except in accordance with a separate MPRSA permit. In addition, dredged materials subject to the requirement of an MPRSA permit are not considered as hazardous wastes under RCRA.2...

Dredge materials subject to the permitting requirements of Section 404 of the Federal Water Pollution Control Act of Section 103 of the Marine Protection, Research, and Sanctuaries Act of 1972 are not considered hazardous wastes. 

In situ methods have potential use as an interim or emergency measure until dredging can be undertaken or as a primary remedial action where it is determined to be more cost-effective than removal. The biggest advantages are that they are much less costly than dredging, eliminate the need for dredged material management, and minimize the resuspension of contained sediments.15...

There is a potential for endrin to be present in soils and sediments at hazardous waste sites. Endrin has been detected in soil samples collected at 44 of the 102 NPL sites and in sediment samples collected at 19 of the 102 NPL sites where endrin has been detected in some environmental medium however, concentrations were not reported (HazDat 1996). Endrin was not detected (detection limit 0.01 ppm [10 ppb] wet weight), however, in soils derived from dredged materials at 9 confined disposal facilities bordering the Great Lakes (Beyer and Stafford 1993).

Given the potential environmental consequences of chemical exposure by the disposal of dredged material worldwide, it is vital that we improve our understanding of its impact on the environment. Through an improved understanding we can minimize the risks associated with the disposed dredged materials. 

The aim of the present study was to identify the DR CALUX bioassay performance criteria for the analysis of PHAHs in sediment samples in order to implement the bioassay in the assessment of dredged materials for systematic monitoring in the eoming years. Therefore, both an intra-and interlaboratory validation study was performed.
