Actually, the issue in Philly was a late change in the EPA fule requirements as they transition from MTBE as an oxygenation additive to Ethanol.
The MTBE was there, but no longer able to be used.
And Ethanol demand is up, so there are not just tankers of it sitting around waiting to be added to gasoline to replace MTBE.
And thus once again, the actual SHORTAGES of fuel are caused by government regulation NOT actual shortages. Same thing we had several years ago when the MTBE requirement was first imposed… SSDD, your government inaction (pun intended)
