CHEMTURA CANADA AUGUST 2013 PROGRESS REPORT



First off this report is being posted much later than usual. Apologies. With both the recently reduced pumping rate at W4 and the long ago reduced pumping rates at W5A & B; I can say that both the on and off-site pumping rates are back on track. Do keep in mind however that W4's target has been reduced from 11.4 to 3.5 litres per second. While there are some promises from a year ago still in the wind to triple the off-site pumping; the reality is that it has been reduced.
Oddly Conestoga Rovers didn't adjust their Figure A.3 to reflect the new lower W4 pumping rate. I did point this out to Chemtura at last months public CPAC meeting.

Appendix B relates to MISA (municipal industrial strategy for abatement) data. While it has a fancy name it's basically simply monitoring surface water combined with infiltrated groundwater discharges into the Canagagigue Creek. Distressing to me is the lack of steady reductions in various chemicals and chemical parameters indicating contamination. Lindane is an example of a chemical they haven't used for years yet its' concentrations at MISA 400 are not decreasing.

The only other issue I see is the ongoing discharges of ammonia and nitrosomorpholine into the Canagagigue Creek. While these are being kept below the requirements they are above the effluent objectives. These measured discharges along with all the unmeasured ones from the site limit any improvements in the "Gigs" quality.
