The United Steelworkers says that Sunoco Inc. has agreed to disclose information on its safety policies and track record at refineries and other production facilities.

The steelworkers, who represent refinery workers, said the Philadelphia refiner agreed to disclose process safety management events in its annual corporate responsibility report. The union said Sunoco will also disclose and explain its worker fatigue policy and has agreed to work with the steelworkers to develop a tracking system to report on the company's performance.

The AFL-CIO Reserve Fund filed shareholder proposals this year calling for similar disclosures at seven refining companies, but said that Sunoco was the only one that complied with the fund's call for increased transparency.

Company spokesmen were not available for comment.    - Andrew Maykuth
