The files of the Office of the President of the Parliament of the Socialist Republic of Croatia in the period 1978-1982 include the preserved petition with copies of 3,002 signatures from Omiš residents opposing construction of a sintered magnesia factory in that area. The petition drive in Omiš was organised on 7 April 1979. It was signed by 3,002 persons: 2,540 eligible voters and 462 students under 18 years of age. According to the file cover, Parliament received the petition on 12 April 1979, and placed it ad acta ten days later, on 24 April. Besides Parliament, the conclusions from the town meeting and the petition with copies of all 3,002 signatures were also sent to the Omiš Municipal Assembly and to a range of republic-level institutions, and to participants in the Second Conference on Adriatic Protection, held at that time on the island of Hvar. That campaign resulted in further debate on the matter by the professional and general public.
