EPA Performance Specification 5 Study Guide
Master EPA Performance Specification 5 (PS-5) for Total Reduced Sulfur (TRS) Continuous Emission Monitoring Systems. This comprehensive tutorial breaks down installation criteria, 7-day drift assessments, and Relative Accuracy Test Audit (RATA) rules for stationary sources like pulp mills and refineries. Essential for environmental engineers and QSTI exam preparation.
In this guide, we dive deep into the unique compliance metrics mandated under PS-5:
Calibration Drift (CD) Requirements: Ensuring your daily zero and span checks stay within 5% of the span value.
Relative Accuracy (RA) Criteria: Achieving an RA of 20% of the Reference Method (RM) mean value, or within 10% of the applicable emission standard using EPA Method 16, 16A, or 16B.
Sampling Pitfalls: Managing scrubbers, particulate filters, and thermal converters to avoid low TRS bias.
