TCEQ Evaluation of Wolf Eagle Study for DISH, Texas

Summary

• The highest potential 1-hour maximum benzene concentration is below the health effects level observed in short-term animal and human studies; however, it is possible that adverse health effects could occur from exposure to this concentration. It was not possible to determine if residents were exposed to this concentration of benzene based on the information provided.

• The Toxicology Division (TD) is concerned that the monitored concentrations of benzene at several of the sampling locations could pose a long-term health risk to residents in the area if the concentrations are representative of normal and prolonged ambient conditions.
• Several monitored and potential 1-hour maximum concentrations of target compounds and tentatively identified compounds (TICs) could have resulted in odorous conditions. Persistent or recurrent exposure to levels which significantly exceed the odor threshold may cause odor-related effects such as headache and nausea. This is consistent with citizen reports of odors in the area.
• The TD strongly recommends additional sampling in the area.
