| Appendix A - Emission Quantification Techniques
Appendix A contains a discussion of two basic test methods used to quantify fugitive dust emission rates: (1) the upwind-downwind method that involves the measurement of upwind and downwind particulate concentrations, utilizing ground-based samplers under known meteorological conditions, followed by a calculation of the source strength (mass emission rate) with atmospheric dispersion equations; and (2) the exposure-profiling method that involves simultaneous, multipoint measurements of particulate concentration and wind speed over the effective cross section of the plume, followed by a calculation of the net particulate mass flux through integration of the plume profiles.

Appendix C - Methodology for Calculating Cost-Effectiveness of Fugitive Dust Control Measures
Appendix C contains a step-wise methodology that allows one to calculate the cost-effectiveness of different fugitive dust control measures. In compiling information regarding control cost-effectiveness estimates (i.e., $ per ton of PM10 reduction) of different control options for the fugitive dust handbook, Countess Environmental discovered that many of the estimates provided in contractor reports prepared for air quality agencies for PM10 SIPs contain either hard to substantiate assumptions or unrealistic assumptions. Depending on what assumptions are used, the control cost-effectiveness estimates can range over one to two orders of magnitude. Consequently, users of the fugitive dust handbook would get a distorted view if these estimates were published. It is recommended that one calculate the cost-effectiveness values for different fugitive dust control options using the step-wise methodology developed by Countess Environmental utilizing current cost data and assumptions that are applicable for their particular situation.
