What specific environmental violation is Chevron's Tengiz oil field accused of by Kazakh authorities?

Chevron-led Tengizchevroil LLP is accused by the Atyrau region’s Department of Ecology of 'accumulation of waste without an environmental permit stipulating accumulation limits,' as confirmed by the Ministry of Ecology and Natural Resources in its official reply.

What is the current legal status of the accusation against Tengizchevroil?

The inspection findings are under pre-trial appeal by Tengizchevroil to the Committee for Environmental Regulation and Control, and as a result, the procedure for holding the company administratively liable has been suspended pending resolution of the appeal.
