40 CFR 63.7e3 Explained | NESHAP Performance Test Run Requirements

A comprehensive legal and technical breakdown of 40 CFR Part 63.7(e)(3), the crucial paragraph within the NESHAP (National Emission Standards for Hazardous Air Pollutants) General Provisions that governs performance test run requirements.

When testing for Hazardous Air Pollutants (HAPs) under Maximum Achievable Control Technology (MACT) standards, meeting the general testing guidelines is vital. Under 40 CFR 63.7(e)(3), the EPA mandates that each performance test must consist of at least three separate test runs, with specific requirements on sample runtime and arithmetic averaging. In this video, we break down how to

properly structure your field timeline, what constitutes a valid run, and how to stay strictly compliant during a source evaluation. 📌 What You'll Learn: • The specific rule text of 40 CFR 63.7(e)(3) and how it fits into Part 63 Subpart A • The 3-Run Rule baseline for compliance tracking of industrial toxic air emissions • Determining test run lengths (why 1-hour minimums are standard under NESHAP) • Data reduction protocols: Calculating the arithmetic mean of the test runs • Dealing with field variables: What happens if a run is cut short due to process disruptions?
