1 min read

The Bay Area Air Quality District received another report of “coke dust” coming out of the refinery in Martinez Saturday evening

Air quality officials teamed up with Contra Costa Health (CCH) to investigate further.

Investigation reveals that CCH hazmat crews and the Bay Area Air Quality District did not find evidence of the coke dust in the surrounding areas of the refinery located at 1801 Marina Vista Ave.

Coke dust is a byproduct of refining petroleum. The release of the coke dust was reported to be at 6:04 p.m.

On July 11, hazmat crews responded to a similar incident.
