20250102 13220300 1.0 ISO19115_3 TRUE This feature layer is associated with the Uniform Buffers dashboard of the Power Plants and Neighboring Communities (PPNC) 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. The PPNC Uniform Buffer feature layer includes the points (PPNC_Points) and 3-mile buffers (PPNC_Buffers) for PPNC 2022 eGRID power plants for the Power Plants and Neighboring Communities application. The 3-mile buffer methodology creates summary information for the surrounding areas of a power plant. This feature layer is generated by joining fossil fuel-fired power plant characteristics and emissions data with socioeconomic characteristic data. 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 EPA including <a href='https://wcms.epa.gov/egrid' rel='nofollow ugc'>Emissions & Generation Resource Integrated Database (eGRID)</a> and <a href='https://www.epa.gov/power-sector/power-sector-data' rel='nofollow ugc'>Power Sector Emissions Data</a>. 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. Additional total population data and socioeconomic information including age distributions, income, educational level, race, household language, and employment status are calculated for the 3-mile 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 Summary dataset (2018-2022</a>) (ACS).
