The Environmental Protection Agency (EPA) has fined Waste Management of Massachusetts for the third time this year for exceeding the state’s five minute idling limit. Waste Management will pay $27,200 for excessive idling at its Stoughton, Taunton and West Boylston, MA depots.

EPA has collected $329,500 in penalties this year from Capitol Waste Services, Allied Waste Services, and Waste Management for idling violations following inspections in 2007 and 2008 of numerous locations where trucks park.

According to EPA, Waste Management and Allied Waste have agreed to make operational changes to limit idling, and Waste Management promised to retrain drivers and inspect all of its Massachusetts facilities daily.
