Notes:

  1. Emissions from natural sources such as biogenics and wildfires are an option in the CEPAM Trend Tool. They are not included in the reports at the top of the page (reports for year across pollutant).

  2. Regarding emissions from Ocean Going Vessels (OGV) and Commercial Harbor Craft (CHC), the reports at the top of this page (emissions for year across pollutant) include emissions out to 100 nautical miles from shore. Regarding the CEPAM Trend Tool, the statewide reporting default for OGV and CHC is 3 nautical miles from shore. When running a statewide report from CEPAM, if the user desires emissions out to 24 or 100 nautical miles, it must be selected in the report run.
