BOD Load
Milk processor Total Plant BOD Load (kg/yr)
Extra Strength BOD Load (kg/yr)
Approximately 25 Extra Strength (high load) users Six of them are contributing to the higher load (80-85% of total)
Extra Strength BOD Load (kg/yr)
SLIDE 16
Extra Strength Industrial Load
Extra Strength (High Load) Industrial BOD growth could drive need for earlier plant expansion. Options
- Impose Pre-treatment for new industries to certain limits
- Impose limits for existing industries (phased in)
Such measures may impact industry investment in community.
