Read this as a district figure, not a state figure. The EIA weekly on-highway diesel survey prices the United States, its districts and California, and nothing else. It does not price South Dakota. The number above is Midwest (PADD 2), series EMD_EPD2D_PTE_R20_DPG, and it is the closest published federal figure for South Dakota. We do not estimate a price for South Dakota from it. 4 of South Dakota's neighbouring states sit in the same district and therefore show the same price below.
EIA does not publish a weekly on-highway diesel price for South Dakota.

Neighbours in the same EIA district carry the same published figure. A matching price here means the federal survey shows no measured gap across that border, not that pumps are identical.
