Introduction As a direct result of the Canada - U.S. Great Lakes Water Quality Agreement of 1978 and its 1987 revisions (GLWQA), participating federal, state and provincial agencies, in cooperation with the International Joint Commission (IJC), identified 43 polluted areas on the Great Lakes as individual Areas of Concern (AOCs), for which a cleanup or Remedial Action Plan (RAP) was required. Seventeen AOCs are in Ontario, and four are located on the north shore of Lake Superior. Nipigon Bay is the lake's most northerly AOC. The Stage 2 document Remedial Strategies for Ecosystem Restoration, building on the remedial actions selected in the Discussion of Remedial Options in the Nipigon Bay AOC, outlines stakeholder commitments and implementation timetables necessary to restore the impaired beneficial uses identified in Stage 1 Environmental
