Over a period of thirty-eight years, Unocal Corporation spilled as much as
20 million gallons of petroleum into Central California's Guadalupe/Nipomo
Dunes fouling the ground water, the beach, and other habitat pro during wha
t may be the largest petroleum spill in United States' history. A whistlebl
ower finally reported this spill in February of 1990. which led to the shut
down of their oil field fines, and criminal charges. Through the analysis o
f oilfield social and organizational dynamics. this article maker three int
errelated contributions to current understandings of hazard creation and re
sponse and organizational deviance. First, it builds on and extends researc
h on "man-made disasters." I argue that commonplace social and organization
al structures. combined with equally unremarkable, yet incrementally cumula
tive petroleum spillage to produce a remarkable outcome-millions of gallons
of petroleum contamination. Second, in addressing the social dynamics at t
he oil field, I develop the theoretical concept of a culture of silence to
capture the collective secrecy that surrounded the spill once the local wor
kgroup recognized the danger ii presented to their ongoing organizational v
iability. Finally an understanding of these serial and organizational dynam
ics suggests significant policy ramifications concerning the viability of c
urrent industrial self-regulation as a strategy for monitoring environmenta
l compliance.
