This Act is P.L. 93-320 (June 24, 1974), and the laws authorising three other conservation cost-sharing programs, were repealed in the FAIR Act of 1996 and replaced by a new cost-sharing program, the Environmental Quality Incentives programme (EQIP). Until it was replaced, the Colorado River Basin Salinity Control programme provided cost-sharing assistance to producers to instal on-farm irrigation system improvements to prevent irrigation water heavily charged with salts and minerals from reentering the river. Participating farmers received up to 70% of total project costs and technical assistance. Participation was concentrated at sites where problems existed. This programme was available to producers in the seven states of the Colorado River watershed. The law was administered by the Farm Service Agency until FY1996, when administration was transferred to the Natural Resources Conservation Service.
