Texas City Refinery Incident:

Some of the things that Dick did not mention. The Texas City refinery was built and operated by AMOCO, BP acquiring it as a running concern in 1998. Now the proposed modifications that could have prevented the explosion all pre-date 1998 (i.e. The modifications were turned down not by BP but by AMOCO)

In 1998 how many AMOCO employees were changed out, or did the work-force remain in place?

If the work-force remained in place then so would the work practices and safety culture. What did the OSHA reports on the Texas City refinery state about the place when AMOCO ran it?
