RICHMOND — The Chevron oil refinery in Richmond has agreed to pay $192,000 in fines to settle 19 air quality violations that occurred over a two-year period and are unrelated to the big fire at the plant on Aug. 6 last year.

The infractions covered a range of problems, from inadequate record keeping and maintenance to excessive emissions from plant flares, according to the Bay Area Air Quality Management District

“We take record keeping seriously because without records, you don’t know what pollution is going on at the plant,” said Wayne Kino, the air district’s director of compliance and enforcement.

The penalties — averaging $10,000 per violation — are intended to remind Chevron to be vigilant in operating and maintaining its plant to minimize emissions, he said. The violations occurred during a two-year period from 2010 to 2012.

Meanwhile, the air district and several other pollution enforcement agencies are conducting a separate investigation into the Aug. 6 refinery fire that sent 15,000 people to visit area hospitals and shut down the heart of the refinery for months.
