The Ganga Action Plan (GAP) Phase - I which was taken up as 100% Centrally funded scheme and aimed at preventing the pollution of river Ganga and to improve its water quality. The plan was started in June 1985. The program of river cleaning was extended to other major rivers of the country under two separate schemes of GAP Phase - II and the National River Conservation Plan (NRCP). Yamuna and Gomati Action Plans were approved in April 1993 under Ganga Action Plan Phase - II. Programs of other major rivers were subsequently approved in 1995 under NRCP. After launching of NRCP in 1995, it was decided to merge GAP II with NRCP. A notification of this effect was issued on 5.12.96.
