"On 24 May, an inspection of the Black Sea waters found a spill of oil-containing fluid 790 meters (0.5 miles) off Tuapse's coast. City authorities introduced the high alert to arrange for cleaning work," the statement read.
Six vessels designed specifically to tackle emergencies were deployed to treat the spill, according to EMERCOM.
While the emergency authority did not specify the size of the oil patch, the regional office of Russia's environmental watchdog, Rosprirodnadzor, said that the threshold limit set for dangerous water pollutants hadn't been breached.
