The Department of Environment has issued a directive to Northern Pulp to complete an independent engineering review and evaluation for the entire power boiler system by Nov. 30. The evaluation must include recommendations for any necessary operational modifications, and capital upgrades intended to bring power boiler emissions to within the company’s approval limit. According to stack test results conducted at the mill in September by Stantec, the power boiler emissions are above the acceptable limit. The results also show that the new precipitator installed earlier in the year continues to operate well below the mill’s approval limit. The emissions limit in the 2015 industrial approval is almost 80 per cent lower than the mill’s previous approval. Testing was done Sept. 15-18 by Stantec Consulting Ltd. The stack test results can be found at http://novascotia.ca/nse/issues/northern-pulp.asp .
