Petrochemical releases disproportionately affected socially vulnerable populations along the Texas Gulf Coast after Hurricane Harvey.

Hurricane Harvey resulted in a natural-technological disaster in which flooding caused petrochemical facilities to release hazardous chemicals. Natural-technological disasters are rarely analyzed from an environmental justice (EJ) perspective. We calculated a Hurricane Harvey petrochemical hazard density index (PHDI) based on the locations of 42 facilities with reported releases along the Texas Gulf Coast. We used sociodemographic data from the American Community Survey to examine census tract-level social inequalities in PHDI (n = 1099 tracts). Results from generalized estimating equations indicate that tracts with higher proportions of Hispanic, disabled, or young residents had greater PHDI. PHDI was positively associated with tract poverty, with a slight downward curve at high poverty. Under conditions of higher Hispanic composition, the positive effect of poverty on PHDI was amplified. With more frequent storms predicted, regulatory agencies need to ensure that the petrochemical industry prepares for rapid shutdowns in order to protect residents from natural-technological disasters.
