  15. 15. Test Programs Large Stockpiles Nutrient Testing Compost Amendment Goals$ Observe the behavior of parameters in large stockpiles with no treatment Assess impacts of adding nitrogen, heat retention & anoxic conditions Accelerate reduction of PAH and PHC concentrations by adding to compost Length$ 2 years 1 year 6 months Lab$Results$$Table$ 1$&$2$SC$ Reduction PAHs EC, boron, SAR were just above Table 2 SCS in one or more samples Variable results for PHCs N was being used to support bacterial growth Thinner stockpile – most promising results Reduction in PAH Samples met CCME & Ontario stds for metals Consulting with MOE re acceptable limits for PAHs and PHCs
  16. 16. ! Database$Framework:$$Start$using$as$a$planning$ tool$for$proactively$managing$excess$material$ ! Betaftesting:$$Provide$access$to$Region$and$Area$ Municipalities$Staff$$ ! Continue$dialogue$with$the$MOE(CC)$on$options$ for$beneficial$sediment$end$uses$
