In March 1974, Soviet General Secretary Brezhnev proposed that the BAM would be one of the two major projects in the Tenth Five Year Plan (1976–80). He famously stated that "BAM will be constructed with clean hands only!" and firmly rejected the suggestion to again use prison labor. A few weeks later he challenged the Young Communist League (Komsomol) to join in "the construction project of the century". 17th Komsomol congress (held in April 1974) announced BAM a Komsomol shock construction project, created the central Komsomol headquarters of BAM construction, and appointed Dmitry Filippov the chief of the headquarters.
