A Kentucky man who owned a towboat that sank and discharged oil in a Tri-State river in 2018 was sentenced to federal probation Monday and his companies were fined. David K. Smith, of Paducah, Ky., was sentenced and his companies – River Marine Enterprises LLC and Western River Assets LLC – were each fined $100,000 and placed on corporate probation. The defendants were also ordered to pay $1.8 million in restitution. Prosecutors said a towboat, the Gate City, owned and operated by Smith’s companies sank while docked along the West Virginia shore of the Big Sandy River in January 2018, discharging oil and other substances in the river. As a direct result of the spill, the city of Kenova had to close its municipal drinking water intake for three days while various regulatory agencies took action and responded to the spill.
