    Abstract

    Nowadays,air pollution has become a major concern. Typically construction equipment plays a major role in emitting a huge amount of pollutants. In order to address this issue, there is a need to measure the level ofuncertainty for decision making of air quality modeling and emission inventories' This paper aims to propose a methodology for quantifuing uncertainty of emission rates of heavyduty diesel (IIDD) consffuction equipment. The objective of this paper is to quantifu the variability and uncertainty of emission rates of HDD construction equipment for three different pollutants (NO*, CO, and HC). The study conducts its study based on 17 backhoes obtained from the City of Stillwater's fleet management database. Horse power (IIP), cumulative hours, activity factor, and emission factors at steadystate condition are assigned as uncertain variables. Monte Carlo simulation was used to model the distributions of the uncertain variables by randomly selecting input values to produce a wide range of output using cumulative distribution functions. A sensitivity analysis was also performed in order to determine which variables that have the greatest impact on the total emission rates.
