KIEV, June 26 - Ukraine’s third-largest oil refinery by capacity, Kherson Oil Refinery, will resume operation in July after more that three years of staying idle, an official at the local Kherson government said Thursday.

The refinery is expected to refine 450,000 metric tons of crude oil between July and the end of December, and will focus on purchasing Caspian Sea crude oil, the official said.

“The first contract on the supplies of 90,000 metric tons of Caspian oil has been already signed,” the official said.
