SHREVEPORT, La. - A unanimous Second Circuit Louisiana of Appeal panel on Oct. 2 ruled that pollution exclusion clauses in commercial general liability policies issued to an oil and gas extraction company relieve the insurers from defending and indemnifying the insured in a legacy pollution lawsuit seeking groundwater and soil contamination damages (Lodwick v Chevron USA Inc., et al., No. 48,312, La. App., 2nd Cir.; 2013 La. App. LEXIS 20119).
