Issues & Opportunities #1 Extra Strength (High Industry Load) 15
Load There are approximately 25 processing industries in Abbotsford and Mission, discharging high load to the Total Plant Load (kg/yr) JAMES Plant (Extra Strength Industries) 44% of Total Six of them are contributing to the Load Extra Strength Load (kg/yr) extra strength load (80-85% of total): - Milk Processor - Fruit Processor - Transportation of food grade liquid/dry goods - Chicken/turkey processor - Sprouted grain bread bakery Milk processor 16
Extra Strength Industrial Load - Significant increase in loading was observed in recent years - Increase in loading can accelerate the need for upgrading secondary treatment - Staff consulted with six highest load industry in May 2016: - All industries are expecting significant growth in the near future - Onsite pretreatment was discussed. Concerns about footprint, potential cross-contamination with food-grade processing plants - Staff to continue monitor the load from these industries, and to review the current rates for full cost recovery, and provide options.

Issues & Opportunities #3 Plant Resiliency Flooding & Seismic 24
Flooding • Plant currently is protected from Fraser River flood of record (1894) by Matsqui Dyke • Ability of the dyke to adapt to climate change is being reviewed as part of the City’s Drainage Master Plan 25
Seismic (Timeline) JAMES Plant Stage 7 Stage 2 constructed (Phase 1) Stage 3 (Stage 1) Stage 5 Stage 4 Stage 6 2000s 1980s 1990s 2010s 2017 Building Code Building Code (2005/2006) Building Code (Updated) (1:475 year) (1:2475 year) (2010/2012) - Tanks (Sloshing) - Concerns with liquefaction (soil to jelly) + (1:2475 year) - Building Horizontal/Vertical settlements - Slumping towards River 26
Seismic • Plant was designed to the 1:475 year event Structures meet requirements for normal importance factor for 1:475 – • magnitude ~ 6.5 Mirror other Municipal seismic upgrades – under review • Existing infrastructure will be used until end of life • • Objective for new structures to meet current standards • Potential seismic barrier at Fraser River • New buildings to 1:2475 - magnitude 7, for post disaster importance per BC Building Code, and incorporate changes in 2015 NBC. • New tanks design to engineering best practices for liquid retaining structures – more strict than building code 27
Issues & Opportunities #4 Odour 28
MISSION N JAMES Plant odor is in line with typical treatment plants • Goal is to meet ambient air quality objective of <0.005 ppm Total Sulphur (Desirable level from Metro Vancouver’s Ambient Air Quality Objectives) • This is being met at the property line JAMES Plant MATSQUI FIRST NATION 29
Odour Perform Odour Study • Audits - H2S continuous monitoring for up to 1 week Review current system for leaks and efficiency • Biofilter Sulfatreat 30
Odour Possible future upgrades: • Covering various primary and secondary tanks • Would require adding a second biofilter 31
Issues & Opportunities #5 Biosolids 32
Biosolids (Timeline) JAMES 5 year Ceased Val-E-Gro™ Biosolids hauling Expansion of Costly.

Biosolids (Production) 2016 2041 (Current) (Projection) Annual Production 5,400 8,250 (Wet Tonnes) Estimated Budget ~$400K ~$600K* *Note: Estimation based on current rate 34
Biosolids What solids treatment / biosolids disposal options are available? • Microwave enhanced oxidization, pilot project • Reduces biosolids & produces more gas in Digesters • Potential study - Drying Biosolids to reduce weight • Land application seems to be best current solution Long trucking distances to locations further away • How to Reduce, or Reuse sustainably? • Request for Proposals (RFP) in the future to determine options 35
Issues & Opportunities #6 Biogas 36
Biogas • Biogas is produced from the anaerobic digesters ~2,500,000 m 3 /year. • Half of this is used for process and space heating; half flared – unused resource. Flare at the JAMES Plant • Between 1983 to 2012, the Plant produced electricity using co- generation. • Explore opportunities: – Create electricity – Sell gas on grid 250 kW Waukesha Engine 37
