SANTIAGO, Feb 14 (Reuters) - Chile's environmental regulator, the SMA, said on Tuesday that it was eyeing sanctions of state-run energy producer ENAP after finding infractions relating to emissions and noise at its Aconcagua oil refinery.
The SMA said it had found 17 infractions, including carbon monoxide, nitrogen dioxide and sulphur dioxide over the allowed limit, and unacceptable noise levels during both day and night.
ENAP now has either 10 days to provide an action plan to address the issues, or 15 days to present its defense.
Chile has two main oil refineries, both run by ENAP - Aconcagua, in central Chile, and Bio Bio, in the south.
