3. OVERVIEW OF TASK ORDERS AND RECOMMENDATIONS TO THE CITY COUNCIL:
a. Interconnect Pipeline
1. Alternatives Overview
2. Recommendation: Selection of Preferred Approach.
b. Instrumentation and Controls Review
1. Findings from 10/17 Site Visit
2. New PLC system is needed to accommodate required instrumentation.
3. A temporary local PLC will be installed at CCB
4. Additional improvements TBD...
c. Tracer Study
1. Tracer study to be completed after the irrigation season is over.
2. Protocol (which must be approved) will need to address how the system will be operated in 2024 season (with improvements made this winter) and operated after all improvements are made.
3. Goal is to complete tracer study (and Title 22 Report) before beginning of 2024 Irrigation Season
4. Title 22 Report will also include description of how system will operate in 2024 season (with improvements made this winter) and operated after all improvements are made.
5. Recommendation: that City move forward with all necessary control system improvements in FY 24/25.
1 d. Title 22 Report:
1. COGC Investigation
A. Mapping
1. Mapping completed successfully.
2. Storm drains are present in the irrigated area.
3. Mapping team did observe several areas where overspray into yards is likely
B. Cross Connection Study
4. Study will be completed after the irrigation season has ended. (Potable/Stormwater, which is used in the winter months for irrigation, will be pumped into the recycled water system for the study)
5. Study will need to be coordinated with installation of new irrigation system at the neighborhood entrance.
C. Dye Study
6. Mapping information should be adequate to satisfy the Regional Board that interconnect with the storm drain system is not likely.
7. Dye Study, which would involve adding dye to the irrigation system water and observing the water goes to prove there is no interconnection, would only be needed if City feels it is needed to address concerns raised by the community.
8. If dye study were to move forward, it should happen after the Cross- Connection study. We do not want dye to sprayed into people's yards.
9. Recommendation: Should the Dye testing be removed from the scope or should it be done after the irrigation system improvements are made? If the dye testing is removed, the funds may be adequate to allow for West Yost re-inspection of the irrigation system.
e. Cease and Desist Order Recensions
1. Project put on hold until FY 24/25 to accommodate the need to complete the Instrumentation and Controls Review and Pretreatment Program f. Pretreatment Program
1. Scope of work proposed for Council approval on 11/7
