WASHINGTON — The average on-highway price of a gallon of diesel declined half a cent to $2.971 for the week ending September 9, according to the Energy Information Administration of the Department of Energy.
It marked the ninth consecutive week the price has declined, according to EIA data.
The largest decline was 1.7 cents in the Central Atlantic states (New York, Pennsylvania, Maryland, Delaware and New Jersey) followed by a one cent a gallon drop in the Midwest (North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Missouri, Iowa, Minnesota, Wisconsin, Illinois, Tennessee, Kentucky, Ohio, Indiana and Michigan).
Only the Rocky Mountain States (Colorado, Utah, Wyoming, Idaho and Montana) at nine-tenths of a cent and the Gulf Coast (New Mexico, Texas, Arkansas, Louisiana, Mississippi and Alabama) at half a cent posted an increase.
The average price nationally is 27.7 cents a gallon lower than the comparable week last year.
