Product summary description: Facility-process level summary with various fields, including added fields for Pb categories and the mechanism used to assign the categories.  The mechanism can inlcude, in descending order of priority:
- rule assignments or "Rule" (as set within the Emission Inventory System at the time the data were pulled);
- Plant type assignments or "Plant Type" (as defined by the Facility Type field in EIS)
- Source classification code or "SCC"

In addition to the standard EIS fields, this file contains three additional fields as follows:
"New Source_Type": This field indicates when a new source type assignment was used.  These source types will be added to EIS in the future, such that future EIS reports will show this type in the Facility Type field

"Summary sector": This is the Pb summary sector

"AssignType": Includes "Rule", "Plant Type" or "SCC" as described above

STANDARD METADATA:

Data source(s), emissions year(s) & version(s): 2008 NEI version 3

Pollutant(s): Pb (lead)

Sector(s): Point sources only, all records.  Added field with Pb categorization included

Purpose: Lead Policy Assessment and Pb categorization

Full description and/or special instructions, 
including level of spatial and temporal aggregation:

Spatial aggregation is point sources (lat lons are provided in the dataset) and temporal aggregation is annual emissions in tons/year.

Created from Access database "2008 NEI v3 Pb Sector Summary.accdb", query "10a OUTPUT 2008 v3 Pb Facility-Process (for website)".

Special Notes:

The file "2008 v3 pb facility-process w categories" contains the same data used in the Pb Policy Assessment, except for the airports.  In the Policy Assessment, the airports data were replaced with the EPA-only airports emissions.  The 2008 NEI version 3 data included here contains state data that in some cases has overridden the EPA-only data.
