Petroleum Imports and Coastal Zone Management
With its growing net petroleum import position, the U.S. must accept continued dependence on tankers plying its coastal areas. Tankers also carry product exports, of course, a critical...
Results from Minerals Management Service Funded Oil Spill Response Research 1991-1993
Large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil spill response capabilities. This paper discusses Minerals Management...
Recovery of Shoreline Ecosystems Following the
High-pressure, hot-water washing was evaluated as one of several countermeasures for cleaning oiled shorelines. This was the primary treatment method for nearly all treated shorelines...
State Implementation and Enforcement of the Alaska Coastal Management Program
Section 306 the Coastal Zone Management Act of 1992 required participating states to develop a means to implement and enforce their coastal programs. The Alaska Coastal Management Act,...
Guidelines for Digital Environmental Sensitivity Index Maps
New national and international requirements for oil spill planning and response capabilities include identification and mapping of fish and wildlife resources and oil-sensitive habitats....
HAZMAT?Protecting Coastal Resources from Pollution Emergencies
As we've seen over the years, pollution from accidental spills and hazardous waste sites can harm the coastal environment. What can be done? A critical step towards ameliorating the problem...
NOAA, Bioassessment Techniques and the Superfund Process
The National Oceanic and Atmospheric Administration's (NOAA) assessments of SUperfund sites require an evaluation of whether contaminants are present in an aquatic environment of concern,...
Sonoma Baylands: Creating an Environmental Benefit Out of the San Francisco Bay Dredging Crisis
The dredging of shipping channels and ports in San Francisco Bay has reached a crisis. Continued disposal of dredge material in the bay is controversial and an ocean disposal site is not...
