This is an annual emissions inventory of the following pollutants that large facilities in Delaware submit to the State: carbon monoxide, lead, ammonia, nitrogen oxides, coarse particulate matter, fine particulate matter, sulfur dioxide, and volatile organic compounds. Not every facility emits all these pollutants. For instance, a given facility may not use equipment that emits a specific pollutant. This can lead to blank cells within the dataset. Also, it should be noted that emissions values of 0.0001 or less are reported as 0.0001. Please see the "Notes" column of the dataset for facility-specific information.
