National priorities, changing

This Statement was prepared to give you information about acrylonitrile and to emphasize the human health effects that may result from exposure to it. The Environmental Protection Agency (EPA) has identified 1,177 sites on its National Priorities List (NPL). Acrylonitrile has been found at 3 of these sites. However, we do not know how many of the 1,177 NPL sites have been evaluated for acrylonitrile. As EPA evaluates more sites, the number of sites at which acrylonitrile is found may change. The information is important for you to know because acrylonitrile may cause harmful health effects and because these sites are potential or actual sources of human exposure to acrylonitrile.

The legislation was amended on October 17, 1986 with the enactment of the Superfund Amendments and Reauthorization Act (SARA). One of the changes in SARA was to increase the fund from 1.6 to 8.5 billion, and SARA required the EPA to make changes to the Hazard Ranking System to more accurately note the level of danger of sites to be placed on the National Priorities List (NPL). In addition, the NPL must be revised and republished every 2 years, and informally reviewed annually. The term Superfund is derived from the fund of money that is collected by EPA to investigate sites and to... 

Carbon disulfide has been identified in at least 200 of the 1,430 current or former EPA National Priorities List (NPL) hazardous waste sites (HazDat 1996). It is not known how many of the 1,430 sites have been evaluated for carbon disulfide. As more sites are evaluated by EPA, this number may change. The frequency of these sites within the United States can be seen in Figure 5-1. Of these sites, 1 is located in the Commonwealth of Puerto Rico.
