7. Work Plan

8. Policy Principles • SSMP – Chapter 3, adopted 2010 Inland Empire Brine Line Strategic Goals: • Facilitate water supply through groundwater desalting and protecting watershed resources. • Manage and operate the Brine Line system in an environmentally sound and sustainable way. • Provide adequate capacity for existing and projected future customers. • Continue to improve Brine Line system planning and operations.

9. SSMP Goals Immediate Goals • Track all SSO’s by size, cause, and location in GIS. • Reduce number and volume of SSO’s in the Brine Line. • Update and train on the Overflow Emergency Response Plan yearly. • Review Ordinance No. 5 and successors yearly for compliance with WDR updates. • Legally secure all easements required for the operation and maintenance of the Brine Line. • Clean 100% of known Fats, Oils, and Grease (FOG) problem areas according to a schedule that maintains Brine Line capacity. • Identify new dischargers that may contribute FOG and ensure implementation of FOG control devices and/or measures. • Place new FOG problem areas created by new dischargers or discovered by system reconnaissance on the known problem areas list.

10. SSMP Goals • Utilize standard drawings and specifications for all improvements on the Brine Line, and create new standards where necessary. • Complete development of Operations and Maintenance (O&M) Standard Operating Procedures (SOP’s) that have been identified. • Clean Problem Areas list as specified in SAWPA’s line cleaning program. • Clean laterals as specified in SAWPA’s line cleaning program. • Clean siphons as specified in SAWPA’s line cleaning program. • Perform Brine Line Reconnaissance at specified locations in order to determine system cleaning requirements. • Perform cleaning as required. • Update Capital Replacement Program yearly as projects are completed. • Complete Brine Line-Specific Training Protocols that have been identified.

11. SSMP Goals • Have all Brine Line O&M staff complete Brine Line-Specific Training Protocols yearly. • Update hydraulic model with existing and potential future users yearly. • Measure compliance with stated goals and make necessary modifications and adjustments on a yearly basis. • Focus on preventive maintenance, including but not limited to, regular inspection of blow-off valves, air release valves, and maintenance access structures. • Establish a GIS-based system to keep track of all inspections (GIS asset management). • Establish priority indices for structures inspected (based on NASSCO guidelines for sewer lines) • Create a Brine Line file and photograph database. • Establish procedures to follow-up with Dig-Alert requests.

12. Resolution No. 2011-10 Policies • SAWPA constructed the Brine Line for the treatment and disposal of non-reclaimable wastewater, temporary domestic wastewater, and truck dump station discharges • The best and highest use of the Brine Line is the export of salt with the ultimate goal of achieving watershed “salt balance” and requires maximum utilization of the Brine Line •  SAWPA’s vision is to maintain and operate the Brine Line as efficiently as possible, collect charges from SAWPA’s Member Agencies and dischargers for the treatment and disposal of non-reclaimable wastewater, temporary domestic wastewater, and collection station discharges, including charges for the discharge of total suspended solids (“TSS”) and biochemical oxygen demand (“BOD”);

13. Resolution No. 2011-10 Policies • It is the policy of the Commission to accurately and equitably allocate costs to those who generate the costs • SAWPA has implemented a rate structure using a characteristics-based rate that results in a “pass-through” of charges for Flow, BOD, and TSS from the Orange County Sanitation District (“OCSD”)

14. O&M Program Requirements • Defined in SSMP, Chapter 5 and Appendices D-1 through D-9 • Partial List of Activities

15. O&M Program Requirements • Line Cleaning • Mainline • Siphons • Sediment Traps • Laterals • Flumes • Unique features • MAS spacing, siphon shape, scale • 265+ tons of material removed so far FY12

17. O&M Program Requirements • Valve Maintenance • Mainline: gate valves, slide gates • Discharger shutdown • In-pipe storage • Air release/vacuum relief • Reach IV-B, IV-E, V (55) • At-grade, vault • Blow-off – direct bury and vault configurations • Vault locations being reconfigured to eliminate need for confined space entry to use

18. O&M Program Requirements • Line Location – Dig Alert • Automated system to receive work tickets and record action • Database - field marks, meeting results, upload photo • Location Map • Average 235 tickets per month • Maintenance Access Structures (MASs) • 385 inspected FY12

23. Implementation • Resources: • 2 SAWPA field staff • Service contracts with WMWD ($348,000), IEUA ($10,000) • Contracts w/various unit price service providers • Line cleaning • Debris disposal • Closed Circuit TV (CCTV) • Vacuum tanker trucks – normal and emergency response • Potholing • Surveying – pipeline, easement location • Traffic control

24. Activities • Process Improvements: • Collection Station “Fail Safe” Capability • Universal permit applications – hauler and generator • Single liquid waste hauler permit for all 4 collection stations • Coordination forum for Collection Station operators • Emergency notification system • On-line document library • Reach IV-E Shutdown, Cleaning, Inspection, Repair • April 16-25 (10 days) • Reach V – sonar/laser inspection near Cabot Road • 2011 line failure and SSO • April 2012

26. Work Plan • Evaluation • Validate requirements of SSMP • Confirm activities to meet requirements • Define implementation strategies • Strategy pros, cons, costs • Recommend course of action • Recommend any changes to allocation of costs • Goal: effective and efficient maintenance & repair, equitable distribution of costs
