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)
![Page 5: Below Hoover Dam 723 mg/L](https://reader035.vdocuments.site/reader035/viewer/2022062501/56816474550346895dd65861/html5/thumbnails/5.jpg)
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%

Title II Salinity Control Program
• 1984 Amendment- –Authorized 2 units, de-authorized 1–Authorized USDA’s on-farm salinity
control program–Cost share of 30%

Natural Resources Conservation Service
The USDA Program
• Environmental Quality Incentives Program (EQIP)
– Technical Assistance to improve irrigation efficiency
– Financial assistance –
• Provides financial incentives of 75 to 90% of the cost
of the irrigation improvements
• Remaining costs paid by the producers

Title II Salinity Control Program
• 1995 Amendment–Created Reclamation’s Basinwide
Salinity Control Program•Cost share of 30%
• 1996 Amendment–Authorized Up-front Cost Sharing

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 applications receive grants for
construction of salinity control measures• Most projects have been improving irrigation
delivery systems

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.
![Page 24: Below Hoover Dam 723 mg/L](https://reader035.vdocuments.site/reader035/viewer/2022062501/56816474550346895dd65861/html5/thumbnails/24.jpg)
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
