Keep Tri-County Beautiful began as a PA CleanWays chapter in Lawrence and Butler counties. Lawrence County formed its chapter in 1993, while Butler County formed a chapter in 2002. The two groups decided to become an affiliate of Keep Pennsylvania Beautiful in 2005, and thus formed PA CleanWays of Butler-Lawrence Counties, becoming their own 501(c)3 non-profit organization. They then added Mercer County shortly thereafter in 2011.  The organization is supported by the Lawrence County Recycling Office.
