subject to improvement (i.e., reduction) to meet the glidepath for regional haze. Average the 5
yearly mean deciview values reflecting mean visibility on the days with best visibility.
Step 3. Estimate relative response factors (RRF) for each component of PM2.5 and
This should be done by using emissions during the base period in air quality model
simulations performed for a large number of days78. Air quality corresponding with future
77Pre-calculated and ranked extinction and deciview calculations for all Class I areas for
the base period 2000-2004 (using both the “old” and “new” IMPROVE algorithms) are available
on the VIEWS website athttp://vista.cira.colostate.edu/views/. This data can be used to satisfy
steps 1 and 2.
78How many and which days to simulate is discussed in Section 6.3 and in Section 14.1.
