• Description:
  Employee exposure control techniques associated with petroleum refining operations were identified. A site visit was made to Getty Refining and Marketing Company's Delaware Refinery (SIC-2911) in Delaware City, Delaware. The exposure controls studied were at the oil water separation area around the waste water treatment facility and at the benzene (71432) and aromatics product loading facilities. Improved oil water separation facilities and a sour water stripper had been installed at the waste water facility. Hydrogen-sulfide (7783064) concentrations were about 1 part per million (ppm) compared to concentrations of 4 to 5ppm before modifications were initiated. Concentrations of toluene (108883) and xylene (1330207) were minimal. Concentrations of benzene were less than 1ppm compared to an OSHA permissible exposure limit of 10ppm. At the tank loading dock, benzene and aromatic products were metered into tank trucks through a loading arm equipped with a dripless connector. The resultant seal minimized the potential for leaks and spills during loading. Fugitive vapors were recovered via a carbon-dioxide eductor and a flexible hose attached to the tank truck. Long term personal and area sampling indicated that the OSHA permissible limit of 10ppm was not exceeded for benzene, toluene, or xylene.
