ECHO Clean Air Tracking Tool - Emission Screener

Related Links

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:

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.

Reporting Years Information

Reporting years may differ between air emission inventory programs. TRI and Greenhouse Gas reporting occur annually. Greenhouse gas reporting began in 2010, so no emissions data will be populated prior to that year. NEIs are released on a triennial basis (e.g., 2008, 2011, 2014). Searching for interim years will display results for the most recently released NEI as of the selected year (e.g., selecting 'Current as of 2012' will display 2011 NEI data). The reporting year will be displayed on the results page.

Required Field

Please enter either a pollutant name or CAS number

Elevated Risk Areas Information

This search criterion will also include facilities within 5 km of any resulting census tract when an EPA Region or State is selected.

EJScreen Indexes

The checkbox to include facilities within 5 km of a census tract should be used in conjunction with an EPA Region or State.

EJScreen Indexes At or Above 80th Percentile

Select facilities with an 80th or higher percentile of one or more of the supplemental indexes of EJScreen, EPA's screening tool for environmental justice (EJ) concerns. EPA uses these indexes to identify geographic areas that may warrant further consideration or analysis for potential EJ concerns. 

Note that use of this criterion does not designate an area as an "EJ community" or "EJ facility." EJScreen provides screening level indicators, not a determination of the existence or absence of EJ concerns. For more information, see the EJScreen home page.

EJScreen Indexes: Index Type

Select from two methodologies for calculating EJScreen indexes. The indexes are a combination of environmental and socioeconomic information.

The Supplemental Index uses a five-factor demographic index that averages Percent Low Income , Percent Unemployed , Percent Limited English Speaking, Percent Less than High School Education, and Low Life Expectancy.

The Environmental Justice Index uses a two-factor demographic index that averages Percent Low Income and Percent People of Color.

EJScreen Indexes: Based On

This option selects whether the EJScreen index percentiles of a facility are calculated based on a facility’s Census block group or 1-mile maximum. The default is Census block group.

EJScreen Indexes: Compare To

This option selects whether national percentiles or state percentiles are used when determining if a location has one or more of EJScreen's indexes at or above the 80th percentile. The default is national percentiles.

Toxic Weightings

"No Toxic Weightings," will display emissions on the results page as mass quantities. The "Apply RSEI Score" selection will display emissions on the results page as both mass quantities and RSEI toxic-weighted equivalents (mass quantity multiplied by the RSEI toxicity weight), for chemicals that have a toxicity weight.

RSEI uses relative toxicity weights that describe each chemical's toxicity relative to other TRI-reported chemicals. RSEI toxicity weights are based solely on human health effects associated with long-term exposure to chemicals. RSEI toxicity weights range from 0.02 to 1,400,000,000 and are available for over 400 of the more than 600 chemicals and chemical categories on the TRI list. See RSEI Toxicity Weights for more information.

Classification

The ICIS-Air source categorization of the facility/source and pollutant emission status. A facility may have more than one classification, depending on its air emissions. Search by the maximum facility classification:

  • Major - Facilities which meet the definition of a Major source under the 1990 Clean Air Act Amendments. A Major source is one for which actual or potential emissions are above the applicable major source threshold. Major source thresholds for regulated pollutants run from 100 tons down depending on the pollutant toxicity and ambient air quality.

  • Minor - A Minor source subject to Part 61 National Emissions Standards for Hazardous Air Pollutants (NESHAP). These sources are kept under close scrutiny because the standards are health based, and violation could imperil human health.

  • Synthetic Minor - A facility that avoids Major source requirements by accepting permit conditions which limit emissions below major source thresholds.

Benzene Fenceline Monitoring

Please be aware that benzene fenceline monitoring only applies to petroleum refineries.
