In response to state and local agency requests for assistance in information exchange, EPA has designed and is implementing an information dissemination center, known as the Air Toxics Information Clearinghouse. The bibliography provides state and local agencies with citations to EPA publications useful to them in developing and operating air toxics control programs. It contains citations to such document types as health assessments and exposure assessments that have a clear, direct bearing on air toxics work. In addition, it contains references to background information documents for new source performance standards (NSPS) that discuss criteria pollutants. These document references are included because the sources described in the background information documents often also emit noncriteria pollutants and information relevant to noncriteria, potentially toxic pollutants is found in many background documents. Compilation of citations presented here was complete as of December 1984.
