Health officials are monitoring levels of chemical exposure following last week's explosions at a petrochemical plant in Texas. Fires are still burning at the TPC site, but evacuation orders are lifted for Port Neches, Groves, Nederland and Port Arthur. The Texas Commission on Environmental Quality is monitoring the air because of a hazardous gas burning in the fire. Residents are also advised to look out for asbestos debris that might've been blown onto their properties in the explosions.
