A member of the FOX19 News Nation spotted gas prices at $3.95 in Northern Kentucky on Wednesday
Gas prices are creeping up again across the Tri-State to nearly $4 a gallon.
Prices have been spotted at $3.95 in several stations in Northern Kentucky, and $3.99 across the river in Ohio.
This comes after gas prices declined leading up to Memorial Day. The average price in Cincinnati was $3.78 on Tuesday, according to the website GasBuddy.com.
Wednesday's spike could be blamed on reports of a minor spill at a pump station in Kansas. TransCanada temporarily shut down the Keystone Pipeline after noticing the spill.
The pipeline delivers a half million barrels of oil per day to the U.S. from Alberta. It feeds supplies to Cushing, Okla., the delivery point for benchmark crude, and a sustained shutdown could push prices higher this week.
