the user wishes to utilize one of the three output options, then c1 are should be taken in developing
2the model inputs to ensure accurate design value calculations.
4Situations that would effectively preclude the use of the MAXDCONT option to calculate
5meaningful AERMOD design value calculations include the following examples:
6• Separate AERMOD runs for each source or groups of sources.
7o SIP modeling includes 10 facilities for 5 years of NWS data and each facility is
8modeled for 5 years in a separate AERMOD run, resulting in ten separate AERMOD
10• Separate AERMOD runs for each source and each modeled year.
11o 10 facilities are modeled for 5 years of NWS data. Each facility is modeled
12separately for each year, resulting in fifty individual AERMOD runs.
14In the two situations listed above, the MAXDCONT option would not be useful as the
15different AERMOD runs do not include a total concentration with contributions from all
16facilities. In these situations, the use of 24-hour POSTFILES, which can be quite large, and
17external post-processing would be needed to calculate design values.
19Situations in which the MAXDCONT options may be used but may necessitate some
20external post-processing afterwards to calculate a design value include:
21• The receptor network is divided into sections and an AERMOD run, with all sources and
22years, is made for each sub-network.
