On June 11, 2019, Energy Transfer announced a $3 million donation to the City of Mandan in North Dakota to help fund improvements at the Morton Mandan Public Library and Main Street parks that function as community gathering spaces. The donation assisted with a library refresh including a new atrium, office space and bookmobile garage, as well as making much-needed updates to the historic building. It also included enhancements to the adjacent Dykshoorn and Heritage Parks such as a new playground area with artificial turf, restrooms, shade areas, and lighting elements.
