When the wind blows a certain way, residents know to head inside. Quickly. They claim the stench from an industrial hog farm on the edge of town is unbearable. The gigantic “finishing” barn confines as many as 4,800 hogs. That many animals produce a lot of waste, and it’s what Will-O-Bett Farm does with the liquid manure — applying tens of thousands of gallons to nearby farm fields — that prompted a nasty legal dispute with neighbors. Pennsylvania law shields farms from most suits making a nuisance claim, helping Will-O-Bett prevail in the lower courts. The Pennsylvania Supreme Court must now decide whether it will hear the case after plaintiffs filed a last-gasp appeal this month.“People spent their entire life working to pay the mortgage and they can’t go outside now and sit on their own deck and have a glass of wine because it’s putrid here,” said Malcolm Plevyak, a recycling company owner so upset over the hog farm that he ran for and won local office.Will-O-Bett’s owner, Paul Dagostin, declined comment, citing the pending litigation. His lawyer, Lou Kozloff, called the plaintiffs’ claims hyperbolic and unsubstantiated in a legal filing that asked the Supreme Court to decline the case. State regulators have found the farm to be in compliance and said it voluntarily implemented an odor-control plan even though it wasn’t legally required.
