The Rogers Delinted Cottonseed Co. site is located near Farmersville in Collin County. The site occupies 81-acres. The cottonseed delinting facility operated from 1965 to 1984, when it was abandoned. The site may be divided into three separate areas:
Arsenic compounds were used to defoliate the cotton plants. The facility then delinted the cottonseeds by washing them with five percent sulfuric acid to chemically remove husks, lints, fibers, and other suspended particulate matter. The process also included the use of a fungicide to protect the delinted cottonseeds. The spent acid solution from the process area was collected in two surface impoundments. The impoundments were used as settling ponds to separate the suspended solids from the acid solution. The water from the impoundments was discharged by evaporation and irrigation of the cotton fields. A screening site inspection conducted in 1995 identified and investigated the specific areas where hazardous substances were either used, stored, or spilled. Twenty acres, formerly used to grow cotton, were sold to Step of Faith Worship Center on April 27, 1999. The religious group planned to operate a church and a private school on the property.
