National Air Toxics Assessment - Emissions - Texas - 2002, 2005, 2011

The National-scale Air Toxics Assessment (NATA) is a comprehensive evaluation of air toxics in the USA from the EPA, and is based on modeled air quality. NATA also provides cancer and non-cancer risk estimates related to these emissions, but this dataset only contains emissions data. For the risk estimates, please see the "National Air Toxics Assessment - Risk Estimates" dataset in this catalog. This curated version (v1) offers the following benefits: (1) Data for the three years were standardized to have the same variable names and formats across years as appropriate; (2) Datasets are provided in SAS (.sas7bdat), STATA (.dta), and Text (.csv) formats; (3) Checking was done to confirm that there is a one-to-one correspondence between the pollutant code and description, that each pollutant is associated with only one HAP (Hazardous Air Pollutant), and that there is only one record per State, County, and Pollutant.
