Pennsylvania-based utilities company, UGI, and the Bureau of Investigation and Enforcement have submitted a joint settlement regarding a deadly 2011 Allentown natural gas explosion. UGI has agreed to pay $386,000, the maximum fine possible. They also need to increase their efforts to replace cast-iron pipeline that played a role in the tragic incident. The natural gas explosion killed five people, injured dozens, and destroyed numerous homes. The investigation following the event alleged that UGI had ignored warning signs for the explosion. Had they been addressed the catastrophe could have been prevented.
