30-40 DRILLING MUD TYPES- JHE INFORMATION FROM THIS PROGRAM HAS AND 
WILL HAVE CONSIDERABLE APPLICATION IN EPA’S REGULATORY PROGRAM: 
OcEAN DISCHARGE (OUTFALL) RESEARCH 
EMPHASIS WILL BE ON THE DEVELOPMENT OF TECHNIQUES FOR ASSESSING 
THE ECOLOGICAL IMPACTS OF DISCHARGES FROM OCEAN OUTFALLS AND ON 
CONDUCTING STUDIES WHICH SUPPORT MANDATORY MONITORING PROGRAMS FOR 
301(H) PERMIT MODIFICATIONS: [HE RESEARCH ACTIVITIES ON OCEAN DISPOSAL 
HAVE BEEN ORGANIZED INTO THE PROCEDURES FOR EVALUATING SEDIMENTS NEAR 
OCEAN OUTFALLS, AND MIXING ZONE DEFINITION: 
A- PERSISTENCE AND FATE oF POLLUTANTS IN MARINE FooD WeBs 
THE OBJECTIVE OF THIS RESEARCH IS TO DETERMINE IF TOXIC POLLUTANTS 
FROM OCEAN OUTFALLS ARE A PROBLEM TO MAN- JHIS RESEARCH WILL ANALYZE 
THE POTENTIAL FOR HUMAN EXPOSURE FROM FISHERIES SPECIES CONTAMINATED BY 
POLLUTANTS RELEASED FROM OCEAN OUTFALLS- DIRECT UPTAKE WILL BE 
COMPARED WITH FOOD CHAIN ACCUMULATION TO DETERMINE THE MOST IMPORTANT 
ENTRY ROUTE: RELATIONSHIPS BETWEEN INPUT ROUTES, SEDIMENT 
ACCUMULATION, ENVIRONMENTAL DEGRADATION PROCESSES, AND FOOD CHAIN 
UPTAKE WILL BE EXAMINED- IT IS EXPECTED THAT THIS RESEARCH WILL LEAD 
TO BETTER DEFINITION OF EFFLUENT RESTRICTIONS- 
B- PROCEDURES FOR EVALUATING SEDIMENTS NEAR OCEAN OUTFALLS 
THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP PROCEDURES TO 
EVALUATE THE LOCATION, SIZE AND IMPACT OF CONTAMINATED SEDIMENTS NEAR 
OCEAN OUTFALLS AND OCEAN DUMPING SITES- THESE PROCEDURES MAY BE USED
