Some US laws directly apply to Antarctica. For example, the Antarctic Conservation Act 16 U.S.C. section 2401 et seq., provides civil and criminal penalties for the following activities, unless authorized by regulation of statute: The taking of native mammals or birds; the introduction of nonindigenous plants and animals; entry into specially protected or scientific areas; the discharge or disposal of pollutants; and the importation into the US of certain items from Antarctica. Violation of the Antarctic Conservation Act carries penalties of up to $10,000 in fines and 1 year in prison. The Departments of Treasury, Commerce, Transportation, and Interior share enforcement responsibilities. Public Law 95-541, the US Antarctic Conservation Act of 1978, requires expeditions from the US to Antarctica to notify, in advance, the Office of Oceans and Polar Affairs, Room 5801, Department of State, Washington, DC 20520, which reports such plans to other nations as required by the Antarctic Treaty.
