Harold Hommes, fuel specialist for the Iowa Department of Agriculture, says drivers needing diesel in Sioux City, Waterloo, Mason City and the surrounding areas are have had a hard time locating it:
Hommes says there's nothing wrong with the pipeline, one of the suppliers is just low on fuel. While the problem is a frustration to those who use diesel, other drivers are finding some welcome price relief at the gas pump.
Hommes says gas prices in Iowa dropped in part as a result of Wall Street trading.
Hommes says prices dropped over 20 cents a gallon in some areas. Here on the northside of Sioux City, regular unleaded gas is selling for around $3.08 per gallon at many stations. Morningside area stations have been around $3.14.
