摘要

This document has been developed in response to the recognition that there may be a number of States revising their State Implementation Plans (SIP) for Particulate Matter (PM) following the recently proposed revision to the National Ambient Air Quality Standards (NAAQS) for PM(10). State and local agencies need a method of estimating background for size-fractioned particulate as part of SIP development for PM(10) and Fine Particulate (FP). The method for estimating background concentration that is specified in Section 51.13c of Federal regulations uses a concentration measured at a nonurban site in or near the analysis area that is unaffected by near emission sources. This document provides information on how to estimate a PM(10) background value from other measurements when PM(10) monitoring data are not available.
