Chevron stated that the commission must certify the environmental impact report and issue a conditional use permit before construction of the improvements can begin.

The project will upgrade three existing refinery units including the replacement of the hydrogen plant, replacement of a power plant with a new cogeneration facility, and replacement of the current catalytic reformers with a continuous catalytic regeneration reformer.

The project will reportedly improve the refinery’s ability to more efficiently remove sulfur to produce the low sulfur, high-quality transportation fuels like gasoline, jet and diesel, that fuel specifications require.

Mike Coyle, general manager of the Richmond refinery, said: We are pleased to present a comprehensive review of the renewal project to the community. For more than three years, we have worked with the city of Richmond and the Bay Area Air Quality Management District to help ensure this project meets or exceeds regulatory requirements.
