Can TRI be used to determine risk to public health resulting from air toxic emissions?
While the TRI data represent a useful means of identifying potential air toxics sources, these data are not sufficient to accurately determine the magnitude of the public health hazard posed by the emissions from a given facility. For example, TRI provides no information concerning the potential exposure to these emissions. These data are most useful to point out the direction for further analyses of public health risk. In addition to identifying new regulatory projects, these data can be used to make priority decisions for the air toxics regulatory agenda. • What does a TRI deepwell injection discharge listing mean to an area’s ground water resources? A listing for any particular facility may, depending on well classification and operating status, pose a threat to underground sources of drinking water. For that reason, each underground injection listing in the TRI database is checked against authorized facilities; if not properly authorized, the operation will be subject to a complian
