ECHO Clean Air Tracking Tool - Emission Screener
The ECHO Clean Air Tracking Tool (ECATT) is a US EPA interface and repository for Clean Air Act data that can be used to evaluate emissions at stationary sources of air pollutant and analyze general air quality.
The Emission Screener search provides data on stationary sources regulated under the Clean Air Act. These data are reported to several EPA air emission inventory programs:
- National Emissions Inventory
- Greenhouse Gas Reporting Program
- Toxics Release Inventory, and
- Clean Air Markets Division Acid Rain Program and Cross-State Air Pollution Rule.
By comparing data reporting to these emissions inventories, users can identify top emitters and answer questions such as: who is emitting, where are they emitting, which pollutants are they emitting, and how much are they emitting? The search organizes emissions data by facility, industry, or pollutant. Through the facility report, users can access each facility's Air Pollutant Report to view detailed emissions data.
