"Businesses in the Bay Area have a responsibility to protect public health by following air quality regulations," Jack Broadbent, air district executive director, said.
The payment settles 23 violations issued by the air district to the refinery, none of which posed a significant threat to air quality or public health, according to the air district, which said that the violations were "corrected promptly."
Only one violation -- brief offsite odor -- impacted the surrounding community. Six were administrative violations and 15 involved brief violations of emissions limits, according to the air district.
"When violations are discovered, the air district will pursue the necessary enforcement actions," Broadbent said.
When the air district issues the notices, violators must generally respond within 10 days and submit a plan outlining actions to resolve the issue, according to the air district, which has some of the most stringent refinery regulations in the country.
