SPRINGFIELD, Ill. - A pollution exclusion clause in an umbrella policy does not bar coverage for underlying claims arising out of the operation of a confinement hog farm because the smells emanating from the farm are not pollutants, the Fourth District Illinois Appellate Court said Nov. 13 (Country Mutual Insurance Co. v. Hilltop View LLC, et al., No. 4-13-0124, Ill. App., 4th Dist.; 2013 Ill. App. LEXIS 788).
