The Texas Petrochemicals, Inc. facility located near the Houston Ship Channel is the target of a recent lawsuit by the City of Houston stemming from two emissions incidents in 2006. The City became aware of the releases while investigating odor complaints from neighbors. The petition claims that the unauthorized releases of chemicals including butadiene violated the plant’s air permits and Texas’ regulation against nuisance conditions created by air emissions and that Texas Petrochemicals failed to accurately report the incidents. The City seeks penalties of $400,000, attorney fees, costs of court, and costs of its investigation in addition to a permanent injunction prohibiting the plant from violating the Texas Clean Air Act.
