The “Greatest”Water Quality Improvement Effortin the History of the World Facts/Results: The Colorado River Basin Salinity Control Program… • reduced the annual salt load by about 1.2M tons • reduced the concentration at Imperial Dam by 90-100 mg/L • reduced quantified damages by several hundred million $/yr • $50/ton Facts: The Colorado River Basin Salinity Control Program… • existed for more than 35 years • approximately $555 M spent • ($384 M in appropriations and $171 M in cost share) • plus potentially maybe $50- $80M from Program participants Facts: The Colorado River Basin Salinity Program… • multiple federal agencies (Reclamation, NRCS and BLM) • 7 states • hundreds of local agencies, organizations and companies • thousands of individual producers Facts: The Colorado River… • is more than 1450 miles long • drains 246,000 sq-miles (1/12 of the continental US) • has an annual flow of about 16 M acre-feet • had an annual salt load of approximately 9 million tons Facts: The Colorado River supplies… drinking water to more than 30 million people in the US irrigation water to nearly 4 million acres
Salinity Control Program Genesis • Early 1970’s
Salinity Control Program Genesis • Early 1970’s • Salinity of the Colorado River was rising • Significant concerns by Mexico • States were concerned about the implications of the Clean Water Act
Salinity Control Program Genesis • 1973 – created the Colorado River Basin Salinity Control Forum (Forum) • 1974 – passed the Colorado River Basin Salinity Control Act (Act) • 1975 – adopted salinity standards for the Colorado River
Standard (1975) 879 mg/L • Established the numeric criteria. • Initiated a Plan of Implementation. 747 mg/L 723 mg/L
Salinity Control Program 2001 • Funded at about $26 M per year • $10.8 M – Reclamation • $6.9 M – NRCS • $0.8 M – BLM • $7.9 M – cost share • Had put in place measures which would remove approximately 775,000 tons per year • 388,000 tons per year – Reclamation • 324,000 tons per year – NRCS • 63,000 tons per year – BLM
Salinity Control Program 2011 • Funded at about $40 M per year • $ 8.1 M – Reclamation • $19.7 M – NRCS • $ 0.7 M – BLM • $ 11.9 M – cost share • Had put in place measures which would remove approximately 1,218,000 tons per year • 546,000 tons per year – Reclamation • 572,000 tons per year – NRCS • 100,000 tons per year – BLM
2011 Review • Reviewed the numeric criteria and determined to not change it. • Identified a Plan of Implementation.
2011 Review • There are currently measures in place to control 1.2 million tons per year. • This equates to about 90-100 mg/L lower TDS at Imperial Dam.
2011 Review • Modeling by Reclamation shows that without additional salinity control the TDS at Imperial will increase on average by 100 mg/L by 2030. • The Plan of Implementation is to control an additional 644,000 tons by 2030 which will reduce this projected increase by about 50 mg/L.
Reclamation’s Basinwide Program • 2010 Funding Opportunity Announcement • More than $100 million dollars of proposals • Selected 11 projects • Will control about 39,000 tons of salt annually • Cost of about $35 million dollars • $20 million from appropriations • $15 million from cost-share • Will be implemented over the next three to five years • Will open up opportunities for on-farm work
NRCS – EQIP Salinity Control • In 2011 had about $19 million in funding of which about $12 million was obligated in EQIP contracts as follows:
2012 Farm Bill • Since 1996 on-farm salinity control efforts have been funded through NRCS’s Environmental Quality Improvement Program (EQIP) which was last authorized in the 2008 Farm Bill • The Colorado River Salinity Control Program is a small piece of EQIP which is a very small piece of the Farm Bill • Authority under the 2008 Farm Bill expires on September 30, 2012 • 2012 Farm Bill?
Summary • Have put measures in place that reduce the salt load by 1.2 M tons per year or a concentration of 90-100 mg/L • However, salinity levels are projected to increase by 100 mg/L by 2030 without continuation of the program • In order to offset that increase by 50 mg/L we need greater funding under Reclamation’s Basinwide Program and continuation of NRCS’s EQIP with current funding levels, and This is the Greatestwater quality improvement effort in the history of the world!
