In a statement, a unified command group said cleanup and assessment teams found no trace of oil sheen on waters or the shoreline near the refinery within the last 48 hours.

Immediately after the leak, observers saw sheen and residue on nearby beaches and the East Bay Regional Park Department staff closed its Miller/Knox Regional Shoreline for several days afterward.

But crews had seen no signs of oil sheen on open bay waters since Feb. 12, and no sign of impacted wildlife during their incident response.
