NEW YORK - Valero Energy Corporation said on Friday that a leak in the kerosene product cooler of its hydrotreating unit at its 325,000-barrel-per-day Port Arthur, Texas refinery did not have any impact on production.

The leak was discovered on Thursday and may result in emissions from the refinery for a week, the company said in a filing with the Texas Commission for Environmental Quality. (Reporting by Rebekah Kebede; Editing by John Picinich)
