Title

Chino Basin Watermaster Optimum Basin Management Program Update (OBMPU)

Description

The proposed OBMPU continues the Optimum Basin Management Program’s (OBMP) nine Program Elements and describes facility improvements needed to meet the OBMPU’s long-term planning objectives over a 20-year planning horizon. The nine PEs defined in the 2000 OBMP included: • PE 1 – Develop and Implement Comprehensive Monitoring Program. • PE 2 – Develop and Implement Comprehensive Recharge Program. • PE 3 – Develop and Implement a Water Supply Plan for Impaired Areas. • PE 4 – Develop and Implement Comprehensive Groundwater Management Plan for Management Zone 1. • PE 5 – Develop and Implement Regional Supplemental Water Program. • PE 6 – Develop and Implement Cooperative Programs with the Regional Board and Other Agencies to Improve Basin Management. • PE 7 – Develop and Implement Salt Management Plan. • PE 8 – Develop and Implement Groundwater Storage Management Program. • PE 9 – Develop and Implement Storage and Recovery Programs. Project Description Changes from the Previous NOP: The OBMPU Project Description was revised to include any new projects or to omit any irrelevant or completed projects by Stakeholders of the Chino Basin. Projects proposed by Stakeholders were added and categorized by the Program Element within which a proposed project fit. The following is a general description of the changes to the Project Description that have been made: • The Project Description has been modified to consider the addition of 28 new wells, for a total of 206 new wells of various types considered by the overall Program. • The Project Description has been modified to consider the addition of 70,600 LF of pipeline, for a total of 620,600 LF of new pipeline of various types considered by the overall Program. • The number of booster pump stations has been quantified at up to 18 booster pump stations with capacities of up to 10,000 gpm considered by the overall Program. • The number of reservoirs has been quantified at 14 water storage reservoirs with an average storage capacity of 5 MG considered by the overall Program. • The maximum storage space (safe storage capacity) of the Chino Basin has been modified from between 700,000 af and 1,000,000 af to between 700,000 af and 900,000 af going forward. • The new advanced water treatment plant has been modified to a more specific 9,000 afy advanced water purification facility, inclusive of the anticipated appurtenances required to develop such a facility. • The new groundwater treatment facilities at or near well sites and at regionally located sites has been quantified at 20 new groundwater treatment facilities at or near well sites, and 4 new groundwater treatment facilities at regionally located sites.
