The ARTOPNT file provides the point-source locations to assign to stationary area and nonroad mobile sources. The file is separated into sections. Each section starts with a header that contains the SCCs that will receive the point-source locations and allocation factors contained in that section. Within the section, the content and format are similar to the EMS-HAP airport allocation factor files (e.g., ap_af1.sas7bdat).
Each section of the file starts with the following packet:
/LOCATIONS/ <SCC 1> <SCC 2> ... <SCC 9>
for SCCs 1 through 9 that apply to the section. The SCCs must be full 10-digit SCCs separated by spaces. A maximum of 9 SCCs may appear in one /LOCATIONS/ packet. If more than 9 SCCs are needed for a specific section, then multiple /LOCATIONS/ packets can be included in subsequent rows prior to the section to which they apply. In other words, two or more lines in sequence may include the/LOCATIONS/ packet, and all of the SCCs from both packets will be applied to the subsequent section of the file.
Within each section delineated by the /LOCATIONS/ packets, the format is shown in Table 8.88, “Format for ARTOPNT”.

The section ends with the start of another packet (indicated by a new /LOCATIONS/ header line or with the end of the file.
