Moscow — Reservoirs in Russia’s Ust-Luga port did not contain contaminated oil on Monday and had an organic chloride content of 3.5 parts per million (ppm), a level well within the normal range, the energy ministry said.
Organic chloride levels have been closely scrutinised following a major oil contamination earlier this year. Levels are expected to range this week from 3.1-4.4 ppm, the ministry said.
