In 2010, theKeystone-Cushing Pipeline (Phase II) was constructed north to south through Butler County (nearPotwin,Towanda,Augusta,Douglass), with much controversy over tax exemption and environmental concerns (if a leak ever occurs).[9][10] A pumping station namedBurns was built two miles north ofPotwin, and new power lines were built from a high-voltage line 0.3 mile east ofDe Graff.[11]
In an unusual technical glitch, a farmstead approximately four miles northeast of Potwin became the default site of 600 millionIP addresses (due to their lack of fine granularity) when the Massachusetts-based digital mapping companyMaxMind changed the putativegeographic center of the contiguous United States from 39.8333333,-98.585522 to 38.0000,-97.0000.[12][13]
