As long as the control equipment is properly maintained and <br /> operated the proposed equipment will meet the health risk policy of less than 10 cases <br /> in a million . <br /> Emissions will not impose any nuisance or discomfort to any individuals if the equipment <br /> is operated and maintained properly. <br /> 10 <br />
