HERCULES -- Phillips 66 will make a presentation to the Hercules City Council on Tuesday to promote a modernization project at its Rodeo refinery that would increase the recovery of propane and butane from the refining process.

The presentation is part of a campaign to generate public support for the project, which Phillips says will benefit the environment by reducing sulfur dioxide emissions, as well as create well-paying jobs at the refinery and in the surrounding community.

But some residents, especially in Rodeo and Crockett, say the new jobs would be mostly temporary and that the project would bring noise and threaten public safety. Some have warned of the dangers of storing hydrocarbons and transporting them by rail, citing the July 6 explosion of tank cars in Lac-Mégantic, Quebec, that killed more than 40 people.

Phillips' presentation will immediately follow the Pledge of Allegiance and the Moment of Silence shortly after the 7 p.m. start of Tuesday's meeting, at Hercules City Hall, 111 Civic Drive.
