CROIX SENSORY PAGE 02 <br /> PAGE 2 OF 2 $omessence Fragrance Mitigation Plan <br /> The proposed exhaust system will achieve a noticeable reduction in the strength of the <br /> fragrance that is now observed in the surrounding neighborhood and will reduce the <br /> frequency that the fragrance is observed, The.reduction in strength and frequency of <br /> fragrance will come from the carbon filtration of the fragrance within the building and <br /> will come from the up-blast exhausting of the filtered air above the roof of the building. <br /> Overall,the neighbors will experience fragrance at less than one-third of the present <br /> levels. Further mitigation of the fragrancc is not realistic given the simple fact that wind <br /> conditions are sometimes Cahn and calm wind conditions are known to inhibit dispersion <br /> of any exhaust in the air. <br /> The proposed exhaust system,will have the flexibility to add additional ducting inside the <br /> building to adapt to changes in the production layout. The system will also have the <br /> flexibility to add additional filtration in the future. <br /> The Filtration System's quotation itemizes the cost of the replacement filter cartridges, <br /> both the"prefilters"and the"carbon filters". These filters,typically replaced as complete <br /> sets,will have a service life of 30 to 90 days. <br /> The performance of the proposed exhaust system is possible by collecting and testing the <br /> fragrance strength going in to the filtration unit and exiting the filtration unit. Monitoring <br /> the fragrance in the surrounding neighborhood is also possible in order to document the <br /> "before and afters'conditions. <br /> Please call with any questions. <br /> Respectfully submitted, <br /> Charles M.
