Topeka ? The United States Postal Service plans to consolidate seven mail processing centers in Kansas to reduce costs.

The Postal Service said in a news release Thursday that processing centers in Hays, Salina, Dodge City and Hutchinson will be consolidated with the processing and distribution center in Wichita.

It says work at the Liberal processing center will be moved to Amarillo, Texas; the processing center in Topeka will be consolidated with one in Kansas City, Mo., and the Colby processing center operations will move to North Platte, Neb.

No specific dates have been set for the consolidation. Once the centers are consolidated, mail processing work will end but retail and business activity at the seven centers will continue.
