Point Source Emissions
for permitted criteria and hazardous/toxic pollutants.
  • NC Emissions Summary Tool 1993-2012
    includes criteria pollutant, hazardous/toxic pollutant and greenhouse gas emissions for 1993 to 2012.
  • NC Emissions Mapping Tool 2010
    Mapping utility that displays facility location and emissions; parses emissions by facility permit classification as well as by criteria, toxic, and hazardous air pollutants.
Reported and Assumed Emission Inventory
These Excel spreadsheets include all emissions reported for the specified calendar year (like 2012) as well as assumed (most recent previously reported) emissions for all permitted facilities that operated in the selected calendar year. For example, if a facility reported emissions in 2008 and the next collection is 2013, the 2008 emissions will be included in these spreadsheets until the 2013 emissions have been reviewed. The data has been reviewed by DAQ staff and is posted in January 13 months after the end of the specific calendar year. Information about the spreadsheet data is included on the Explanation tab or you can contact Tammy Manning by phone at 919-707-8717 or by email at tammy.manning@ncdenr.gov.
