Response to Comments, AP42 Section 11.19.2 Crushed

2015-9-10  The revised AP-42 Emission Factors for Crushed Stone Processing should, therefore, be viewed in this context as a last resort method of estimating pollutants attributable to crushed stone processing. Many of the revisions to the PM10 and PM2.5 emission factors are generated from mathematical extrapolation methods. With one exception, there is no new test data. Utilization of the old Method 5 data or other EPA approved test methods that generated information for the previous AP-42 versions in 1994 and 1995 are probably more acceptable in the EPA hierarchical scheme than the extrapolated
