As pollution from cars, trucks, and land-based stationary sources has been more tightly controlled over the last 40 years, the contribution of ships and port operations to air pollution in port cities has become more important. In the same period, foreign trade has grown dramatically; thus, pollution from shipping and port operations would be growing as a percentage of total emissions, even if the emissions were regulated to the same degree as other sectors. This book provides information regarding pollution from ships and port facilities and discusses some of the measures being implemented and considered by local, state, and federal regulatory agencies. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.
