The Plan of Implementation • Offset the effects of human-caused activities in the Upper Basin • Maintain the numeric criteria thru 2030 • Target objective – control 1.8 M tons/year • Reduce the economic damages • Enactment of the Colorado River Basin Salinity Control Act (Public Law 93-320)
Salinity Control Act • 1974 – PL 93-320 enacted • Title I – Addresses US commitment to Mexico – Yuma Desalting Plant • Title II – Measures Upstream of Imperial Dam • Authorized 4 units • Cost share of 25%

Reclamation’s BasinwideSalinity Control Program • Reclamation solicits new projects based on a competitive process open to the public • Funding Opportunity Announcement (FOA) • Applications ranked on cost effectiveness ($/ton) and risk factors • Highest ranking applicationsreceive grants for construction of salinity control measures • Most projects have been improving irrigation delivery systems
Basinwide Program Projects • Big Sandy (4) • Manila (1) • Uinta Basin (23) • Price-San Rafael (17) • Paria (1)
Basinwide Program Projects continued • Grand Valley (2) • Lower Gunnison (12) • McElmo Creek (1) • San Juan (2)

Title II Salinity Control Program • 2008 Amendment • Created the Basin States Program • Basin States Program (BSP) • Reclamation administers the BSP in consultation with the Colorado River Basin Salinity Control Advisory Council • Amounts from the Basin Funds used for up-front cost sharing are now administered through the BSP.
Basin States Program (BSP) Reclamation administers the BSP with assistance from state agriculture agencies (SAG) and NRCS thru agreements • Projects will be selected thru a competitive process, i.e. Funding Opportunity Announcement (FOA) or NRCS batching process. • Projects that are too small for Basinwide Program and not eligible for NRCS’s EQIP. • Ranked on cost effectiveness ($/ton) and other factors. • Selected projects will be awarded agreements with the SAG or with Reclamation for construction of salinity control measures
