Chemical Mass Balance Model
Entry ID: CMB8

Summary
Abstract: The Chemical Mass Balance (CMB) Model EPA-CMBv8.2 is one of several receptor
models that has been applied to air quality problems over the last two decades.
Based on an effective-variance least squares method (EVLS), EPA has supported
CMB as a regulatory planning tool through its approval of numerous State
Implementation Plans (SIPs) which have a source apportionment component. CMB
requires speciated profiles of potentially contributing sources and the
corresponding ambient data from analyzed samples collected at a single receptor
site. CMB is ideal for localized nonattainment problems and has proven to be a
useful tool in applications where steady-state Gaussian plume models are
inappropriate, as well as for confirming or adjusting emissions inventories.
