(Reuters) - A San Francisco Bay Area health officer on Thursday lifted
an advisory warning neighbors of a refinery not to eat produce grown in
potentially contaminated soil in the area, after a toxicologist found
public health was not at risk.
The U.S. Department of Justice is investigating the PBF Energy Inc unit
in Martinez, California, over a November emissions release of a "powdery
substance" later determined to be spent catalysts used in refining.
Contra Costa county officials are also probing the root cause of the
incident and the District Attorney is considering legal action against
PBF for not properly notifying the county of the release.
A county-hired toxicologist TRC said on Thursday the release did not
increase the public health risk of exposure to heavy metals in the soil.

The metals detected in 14 soil samples were within an expected range of
levels typically found in the state, the toxicologist said. County
health officials had advised caution in March until soil testing could
be complete.

personally would have no issue eating fruits and vegetables grown in
ground soil from one of the affected areas," said Dr. Ori Tzvieli,
the county's health officer.
A sample collected last year by Contra Costa Health Services showed
above-normal levels of aluminum, barium, chromium, nickel, vanadium,
and zinc.
In February, an analysis report by the refiner said the catalyst
overflowed after valves to keep pressure rising in the refinery's
reactor and regenerator were not adjusted properly.
