EPA's Technology Transfer Network

Updated: Aug 28, 2023

The Technology Transfer Network (TTN) is a collection of technical web sites containing information about air pollution science, technology, regulation, measurement, and prevention. Currently, there are 17 web sites covering subjects such as New Source Review (NSR), emission inventories/emission factors (CHIEF), and news from the Federal Advisory Committee Act (FACA) relating to Ozone, Particulate Matter and Regional Haze . Through these sites one can find tools to estimate emissions, download computer code for models, read a summary of the Clean Air Act, or request technical support in implementing an air pollution control program. TTNWeb also features a public forum for exchange between participants and EPA staff.
