Use of the National Air Toxics Emissions Inventory for prioritizing Title I programs

The Clean Air Act (CAA) requires the US Environmental Protection Agency (EPA) to identify sources and assess the public health and environmental impacts of hazardous air pollutant (HAP) emissions. The CAA, which takes a proactive approach by listing 188 HAPs, requires EPA to list source categories with significant emissions of the listed HAPs, and to issue technology-based emissions standards for those categories. Congress further required that EPA determine whether these standards are adequate to prevent adverse health effects and serious or widespread environmental effects, and to take additional actions as necessary. Additional toxic requirements specified in the CAA include the Urban Area Source Program, Section 112(c)(6), the Great Waters Program, and special studies. Although much has been achieved by the various CAA programs to date, the potential remains for duplication of effort between the various EPA program offices, establishment of redundant or conflicting requirements, and disproportionate spending on relatively low priority program elements. These potential problems underscore the challenge to EPA to create a unified and comprehensive approach to the air toxics problem. In 1996, EPA developed an air toxics strategy that presents a comprehensive vision of how the CAA authorities addressing air toxics should work together in order to be most effective. In order to prioritize and integrate elements within the air toxics programs, data are needed to provide an assessment of the air toxics problem. One tool being used is the National Toxics Inventory (NTI), developed by EPA`s Emission Factor and Inventory Group. This paper discusses the use of the NTI for prioritizing efforts related to Title I Programs, as well as its use supporting the goals of the programs.
