Relating to the regulation of preproduction plastic by the Texas Commission on Environmental Quality.

HB 4028 defines "preproduction plastic" as plastic resin pellets, flakes, fibers, powders, and coloring used in manufacturing. It requires the Texas Commission on Environmental Quality (TCEQ) to classify this material as a Class II nonhazardous industrial waste through regulatory rules. The bill mandates that the TCEQ include pollution from preproduction plastic in water quality monitoring, assessments, and water quality standards under the Water Code. This directly affects the TCEQ's regulatory process and industries that handle preproduction plastic waste, such as plastic manufacturers.
