Title: Calculating the potential to emit particulate matter

As the implementation of the 1990 amendments to the Clean Air Act, and Title V in particular, continues, questions regarding the calculation of a facility`s potential to emit continue to surface. The US Environmental Protection Agency (EPA) has provided limited guidance decisions, although many are still being made during Title V implementation. This paper discusses what is meant by PM-10 and the validity of using sieve analysis in estimating particulate emissions. Title V of the Clean Air Amendments of 1990, and the accompanying regulations in 40 CFR Part 70, defines a major source subject to Title V by calculating its potential emissions of all regulated pollutants, both criteria and hazardous air pollutants. For PM, the threshold emission rate is 100 tons per year (tpy) for applicability to Title V. Much discussion has ensued regarding a definition of PM for the purpose of determining a facility`s potential to emit. Recently, EPA provided guidance which indicated that only PM-10 should be considered for making this determination although many states regulate larger particles through their state implementation plan (SIP) as a surrogate for PM-10.
