OSHA has cited Valero Energy Corp. and proposed penalties totaling $101,750 for alleged safety violations, according to an OSHA press release.

The agency issued the citations alleging 13 serious, two repeat and one other-than-serious violation following an investigation that began Oct. 16, 2007, at the company's Port Arthur refinery. The inspection was initiated as part of OSHA's National Emphasis Program for petroleum refineries.

Serious violations include failing to: implement accurate process safety information, provide employees with accurate operating procedures, have an adequate system in place to advance recommendations from process hazard analysis and correct equipment deficiencies.

The repeat violations address the company's failure to implement inspection and testing procedures that follow OSHA's standards and regulations.

Headquartered in San Antonio, Valero has about 830 employees at its Port Arthur facility, the press release said.
