Public Health Assessment for Patrick Bayou Deer Park, Harris County, Texas. EPA Facility ID: TX0000605329 March 20, 2003

Patrick Bayou is a small tidal tributary of the Houston Ship Channel (HSC) that flows through a heavily industrialized area in Deer Park, Harris County, Texas. This 3 mile long, shallow bayou flows past the property boundaries of three petrochemical industries that discharge treated plant wastes and cooling tower wastewater under permit into the bayou. In addition, Patrick Bayou receives effluent discharges from the City of Deer Park wastewater treatment plant and discharges from an air separation plant located along the east side of the tributary. On June 14, 2001, Patrick Bayou was proposed to the National Priorities List (NPL), because sediment contamination in the wetlands bordering the Bayou posed a threat to downstream fisheries
