Training

EPA has been developing training to support successful renewable projects on contaminated lands, landfills and mine sites.

EPA’s RE-Powering America’s Land Initiative encourages renewable energy development on current and formerly contaminated lands, landfills, and mine sites when such development is aligned with the community’s vision for the site.

AirData - Daily Air Quality Tracker (PDF Report)

This tool plots recent daily AQI values relative to the long-term high/low and recent 5-year average for a specific location and time period.

AirData - Ozone Exceedances

This tool compares 8-hour ozone exceedances between two years or multi-year periods for a city or county.

AirData - Concentration Map

Make a map of daily concentrations over several days. The daily air quality can be displayed in terms of the Air Quality Index or in concentration ranges for certain PM species like organic carbon, nitrates, and sulfates.

AirData - Concentration Plot

This tool makes a time series plot for a specific location and time period. This tool displays daily air quality summary statistics for the criteria pollutants by monitor.

AirData - Tile Plot

This tool plots daily AQI values for a specific location and time period. Each square or “tile” represents one day of the year and is color-coded based on the AQI level for that day. The legend tallies the number of days in each AQI category.
