Bio-Solids Processing Options Report
In both cases, the base assumption is that the products would be used for soild amendment in the tre
planting operation of the mine reclamation project. In the case of the Class A dried granular material,
other options are available.
There is a greater capital investment required to produce a Class A biosolids product at the Lot L site of
approximately $1.3 million. The annual processing cost is also higher. However, the hauling costs are
reduced from $75,000 per year to $10,000 per year. Overall, it results in a Present Worth difference of
approximately $520,000.
The improvements at the Ebb Tide plant required for safety and greater efficiency ar estimated at
$600,000. The combined cost of aerobic digestion and dewatering for a Class B product results in a total
of $4,827,000.; very close to the current $4.8 million budget.
The investment required to produce a dried Class A biosolids product is $6,006,000.; or roughly $1.2
million over the current budget. This additional funding must come from the District of Sechelt, as the
Federal/Provincial contribution $3.2 million is a fixed amount.
