DUMPING PERMIT PROGRAM- ADDITIONAL DATA COLLECTED UNDER THE RCRA 
PROGRAM, THE NPDES PERMIT APPLICATION PROCESS, AND THE POTW 
PRETREATMENT REMOVAL PROGRAM, AS WELL AS OTHER SOURCES, WILL ALSO BE 
USED- CHEMICAL SCREENING RESEARCH WILL EVALUATE HIGH PRESSURE LIQUID 
CHROMATOGRAPHY AS A RAPID SCREENING PROCEDURE FOR COMPLEX WASTES- IF 
THIS PROCEDURE PROVES TO BE USEFUL ON A ROUTINE BASIS, THE AMOUNT OF 
THE MORE EXPENSIVE BIOLOGICAL SCREENING NOW REQUIRED COULD BE GREATLY 
REDUCED- 
B- Exposure ASSESSMENT 
THE EXPOSURE ASSESSMENT PORTION OF A HAZARD ASSESSMENT PROTOCOL 
PREDICTS THE ENVIRONMENTAL DISTRIBUTION AND FATE OF POLLUTANTS- IT IS 
NECESSARY TO DETERMINE NOT ONLY WHERE A POLLUTANT MAY GO IN THE 
ENVIRONMENT (I-E+, SEDIMENT, WATER, OR ORGANISMS) BUT ALSO TO DETERMINE 
AT WHAT LEVELS IT CAN BE FOUND- THIS INFORMATION IS NECESSARY IF 
REALISTIC DOSING LEVELS, AND MODES OF EXPOSURE ARE TO BE USED IN 
EFFECTS STUDIES- EMPHASIS WILL BE ON THE DEVELOPMENT OF EXPOSURE 
MODELS WHICH WILL PREDICT THE LEVEL OF THE POLLUTANTS IN THE 
ENVIRONMENT RESULTING FROM AN OCEAN DUMPING ACTION AND ON THE 
PARTITIONING (DISTRIBUTION) OF POLLUTANTS BETWEEN THE DISSOLVED PHASE 
AND THE PARTICULATE PHASE: 
C- Efrects ASSESSMENT 
THE EFFECTS ASSESSMENT PORTION OF A HAZARD ASSESSMENT PROCEDURE 
WILL DEFINE THE LIMITS OF POSSIBLE ECOLOGICAL IMPACTS OF OCEAN DUMPING- 
TO MAKE AN ACCURATE HAZARD ASSESSMENT FOR SPECIFIC OCEAN DUMPING
