Development of a Fugitive Dust Handbook for the WRAP

摘要

This paper describes the development of a comprehensive fugitive dust handbook prepared for theWestern Regional Air Partnership’s (WRAP) Dust Emissions Joint Forum (DEJF). The handbookcontains separate, stand-alone chapters for eight major fugitive dust source categories with the chaptersgrouped into two broad categories, as follows: (a) Mechanically Generated Fugitive Dust that includeagricultural tilling, construction and demolition, materials handling, paved roads, and unpaved roads;and (b) Wind Generated Fugitive Dust that includes agricultural wind erosion, open area wind erosion,and storage pile wind erosion. The handbook addresses the estimation of uncontrolled fugitive dustemissions and emission reductions and costs associated with demonstrated control techniques. Themethods for estimation of emissions draw primarily from AP-42 and secondarily from alternate methodsadopted by state and local air control agencies in the WRAP region. Sources of data are identified anddefault values are presented for emission factor correction parameters, source extent/activity levels, andcontrol efficiencies for natural mitigation and add-on control measures. Data sources for costs of add-oncontrols are also presented, along with step-by-step case studies for calculating control measure costeffectiveness.In addition, regulatory formats and compliance tools are discussed. Other itemsappended to the handbook include a discussion of test methods used to quantify fugitive dust emissionrates; a summary of alternative emission estimation methods not addressed in the main body of thehandbook, as well as methods that are still in the “developmental” stage and have not been approved byfederal or state agencies; and a step-wise method to calculate the cost-effectiveness of different fugitivedust control measures.
