Antarctic Environmental Protection Act of 1991 - Amends the Antarctic Conservation Act of 1978 to require the Director of the National Science Foundation to: (1) prepare, periodically update, and implement a waste management plan for waste produced or disposed of in Antarctica by U.S. citizens; and (2) issue regulations requiring U.S. citizens in Antarctica to comply with specified waste management practices.

Requires the Director to establish a long-term program for the removal of specified wastes.

Requires the Director to implement an environmental education and training program for all persons engaged in the U.S. Antarctic Program.

Directs the Secretary of the department in which the Coast Guard is operating to issue regulations requiring all vessels to: (1) install compaction, storage, and incineration equipment in the construction of any vessel built after the promulgation of such regulations; (2) stockpile waste, plastic, and other garbage (other than untreated sewage) outside of the Antarctic Treaty area or at U.S. facilities in Antarctica; (3) incinerate waste if stockpiling interferes with the operation of a vessel or affects the life and safety of the crew as long as such incineration is conducted in incinerators designed to eliminate harmful emissions; and (4) discharge waste, plastic, and other garbage at reception facilities outside of the Antarctic Treaty area.

Makes it unlawful for any U.S. citizen to charter, contract for, or employ a vessel unless such citizen has certified to the Secretary that the vessel will comply with the requirements of this Act.

Directs the Secretary to issue regulations requiring potential dischargers to maintain evidence of financial responsibility to cover such costs and damages.

Permits the Secretary to take the following actions with respect to vessels that do not produce evidence of financial responsibility: (1) deny the vessel entry to any U.S. facility in Antarctica; or (2) detain the vessel at the facility. Subjects vessels without evidence of financial responsibility at such facilities to seizure and forfeiture by the United States.

Directs the Secretary to issue regulations requiring owners or operators of vessels operating in Antarctica to submit plans for responding to substantial threats of a hazardous substance discharge into the Antarctic marine environment. Lists plan requirements. Prohibits vessels without approved plans from operating in the Antarctic Treaty area. Absolves the United States from liability for damages resulting from actions or omissions relating to response plans.

Requires the United States to retain civil penalties collected under this Act or restoration and removal costs and damages in a revolving trust account to be used for Antarctic Treaty area protection and for the environmental education and training of U.S. Antarctic Program personnel.

Requires the Under Secretary of Commerce for Oceans and Atmosphere to develop and implement an environmental monitoring program for Antarctica.

Requires regulations promulgated pursuant to the Antarctic Conservation Act of 1978 to include requirements for specially-protected areas. Establishes deadlines for the promulgation of specified regulations concerning: (1) the designation as pollutants of substances liable to create health hazards or harm Antarctica; and (2) actions to prevent or control the discharge of pollutants in Antarctica.
