KODIAK -- A federal grand jury has indicted a Kodiak man on charges of dumping pollutants from his vessel into the harbor at St. Paul in the Pribilof Islands.

The Kodiak Daily Mirror reports 56-year-old Victor Buchanan is charged with dumping oil-contaminated bilge water and raw sewage from the 86-foot commercial fishing boat Chisik Island between Sept. 30 and Oct. 4.

The Coast Guard investigated the incident.

Federal prosecutors say Buchanan faces a felony count of violating federal laws that prohibit discharge of any form of oil into U.S. navigable waters or shorelines and a misdemeanor charge of dumping refuse into navigable waters without a permit.

St. Paul is a village of 481 on the southern tip of St. Paul Island, the largest of the four Pribilof Islands in the Bering Sea.
