Mapping Tool. The PPNC Mapping Tool is a product of the Clean Air Power Sector
Programs as the U.S. EPA Office of Air and Radiation. The tool allows users to explore and
visualize the relationship between power plant locations, their emissions, and
the socioeconomics of surrounding communities across the United States.</font></p>
<p><font color='#000000' size='4'>The PPNC Plant-Specific Buffers feature layer includes the points
(Aermod_Points) and plant-specific buffers (Aermod_Buffers) for PPNC 2022 eGRID
power plants for the Power Plants and Neighboring Communities application.
Plant-specific buffer methodology is produced using EPA’s <a href='https://www.epa.gov/power-sector/power-plant-environmental-justice-screening-methodology' rel='nofollow ugc'>Power
Plant Screening Methodology</a> (PPSM), specifically AERMOD
model outputs from 2021. PPSM uses air quality modeling combined with GIS
analysis to identify census block groups that are potentially exposed to air
pollution from each of the power plants.</font></p>
<p><font color='#000000' size='4'>This feature layer is generated by joining fossil fuel-fired
power plant characteristics and emissions data with socioeconomic characteristic
data.<span> Power plant data is sourced
from the <a href='https://www.epa.gov/power-sector' target='_blank' rel='nofollow ugc noopener noreferrer'>Clean Air Power Sector Programs (CAPD)</a> of

Emissions Data</a>.</span> <span>For all
grid-connected power plants located in facilities with a nameplate capacity of
at least 1 Megawatt (MW), the following data is available: plant attributes,
operating data, emissions, heat input, generation, emission rates, and resource
mix. Socioeconomic characteristics of surrounding communities include people of
color, low income, unemployment rate, limited English speaking, less than high
school education, under the age of 5, and over the age of 64</span><span>. Additional
total population data and socioeconomic information including age distributions,
income, educational level, race, household language, and employment status are
calculated for the Plant-Specific Buffers using the <a href='https://www.census.gov/programs-surveys/acs/technical-documentation/table-and-geography-changes/2022/5-year.html' target='_blank' rel='nofollow ugc noopener noreferrer'>US Census Bureau ACS 2022 5-Year
