The purpose of this Article is to outline those key federal, state, and international regulations that expressly mention or materially affect marine terminal operators in the United States. There are four major areas in which these regulations fall. Part II of this Article will discuss the federal regulation of marine terminal agreements and tariffs. Part III will outline a marine terminal operator's liability for cargo damage under federal, state, and international law. Part IV will address the environmental regulation of marine terminal operators on the federal, state, and international levels, and Part V will discuss those state and federal regulations relating to the protection and security of waterfront facilities. The topic of federal, state, and international regulation of marine terminal operators is a very broad one. By focusing upon the foregoing four major areas of express regulation of marine terminal operators, this Article necessarily excludes the following from its scope: (1) federal, state, or international regulations that apply to United States marine terminal operators indirectly; (2) federal, state, or international regulations that apply to every business, including marine terminal operators, merely by virtue of being in business; and (3) minor or immaterial federal, state, or international regulations that pertain to United States terminal operators.
