The NHAPEXCLUDE file provides a way to exclude sources from the NONHAPVOC or NONHAPTOG calculation. For SMOKE versions 2.6 and higher, a new special header in the NHAPEXCLUDE file to allow Smkinven to either include or exclude sources from NONHAPVOC or NONHAPTOG calculation. When the header is defined as /INCLUDE/, Smkinven will treat selected sources as integrated sources; Smkinven will use the toxics pollutants from the selected sources to compute NONHAPVOC or NONHAPTOG. The toxic emissions will be retained or dropped by Smkinven, depending on the status of the pollutants in the INVTABLE file (see Section 8.10.3, “INVTABLE: Inventory table”). If the pollutant is a model species and an explicit species, then the toxic emissions will not be dropped. If the pollutant is only a model species but not an explicit species, it will be renamed by appending “_NOI” to the species name. If it is neither a model species nor an explicit species, the toxics mass will be dropped to prevent double counting of the inventory mass. When the header is defined as /EXCLUDE/ which is the default setting, Smkinven willl exclude the selected sources from the HAP-CAP integratoin approach. All other inventory sources will be used to compute NONHAPVOC or NONHAPTOG.

The NHAPEXCLUDE file is only used when SMK_PROCESS_HAPS is set to PARTIAL. If SMK_PROCESS_HAPS is set to ALL or NONE, the NHAPEXCLUDE file is not required (Section 6.13.3.2, “Input Environment Variables”). Once integration/non-integration processing is done, Smkreport can create a report that separates integrated and non-integrated sources using the BY INTEGRATE instruction (Section 7.3.3, “Create-report Section”).

NOTE: Whenever SMK_PROCESS_HAPS is set to process HAPs, a new inventory pollutant, “VOC_INV” or “TOG_INV”, will be created to retain the original VOC or TOG values for the purpose of creating quality assurance reports with Smkreport.

The NHAPEXCLUDE file contains the country/state/county and SCC codes of those sources that SMOKE will include or exclude from the NONHAP calculation. The file format is shown in Table 8.86, “Format for NHAPEXCLUDE”.

For area/nonpoint, on-road mobile, and nonroad mobile sources, zeros can be used within the country/state/county code and the SCC code to make an entry more generic. For example, a SCC-only entry would have a zero for the country/state/county code. For a left-2 SCC entry, the final eight characters of the SCC would be zero. The following list illustrates entries for each of the 14 possible cross-reference levels. See Section 2.3.5, “Source Classification Codes” for more information about the different levels within an SCC.

For point sources, the available combinations depend on the source definition. A header is used in the file to indicate the source definition. (The header is required for IDA inventories). For IDA-formatted inventories, a source is defined as the unique combination of country/state/county code, plant ID, point ID, stack ID, segment, and SCC. This documentation applies to IDA-formatted inventories only. “5-digit SCC” means a 10-digit SCC with the last 5 digits set to zero. If only 8-digit SCCs are available, these can be used and SMOKE will assume leading zeros. In this case, the “5-digit SCC” becomes a “3-digit SCC”.

The hierarchy of cross-referencing is the following.
