Design Values are the metrics (i.e. statistics) that are compared to the National Ambient Air Quality levels to determine compliance with the Federal regulations for air quality (40 CFR Part 50). They are specific to each criteria pollutant. For pollutants with more than one NAAQS, distinguished by averaging period, statistical form, and/or level, there is a distinct design value for each NAAQS.
The Design Value Report provides a way of retrieving the Design Values for the pollutants where 3-year statistics are required (instead of annual statistics). These are Ozone, PM 2.5, and PM 10. The Design Value report provides both a formatted report output and a workfile output. Both the report and the workfile have pollutant specific formats – i.e. each pollutant has its own report or workfile format to display the Design Value statistics that are specific to that pollutant.
The following types of data selection are allowed:
• Any Geographical Selection (Required)
• Pollutant: Pollutant Type and Parameter Code (Required)
• Screening Group (Optional)
•
• Monitor Type (Optional)
• Land Use (Optional)
• PQAO (Optional)
The sort order for the report is fixed (not user changeable). The following is the sort order:
Parameter Code (page break)
Design Value Year (page break)
