PS 2 EPA Performance Specification 2 SO2 and NOx CEMS Guide

Learn the comprehensive field and regulatory workflow for US EPA Performance Specification 2 (PS 2)—the foundational standard for evaluating the acceptability of SO2 and NOx Continuous Emission Monitoring Systems (CEMS) at the time of installation or as required by regulations.

Master EPA Performance Specification 2 (PS 2) for SO2 and NOx CEMS validation! This step-by-step technical guide breaks down Calibration Drift (CD) assessments, Relative Accuracy Test Audits (RATA), and compliance procedures for continuous emission monitoring systems. Unlike individual emission test methods, PS 2 outlines the long-term operational accuracy framework for your plant's instrumentation, focusing heavily on measurement location, calibration drift, and relative accuracy testing. In this video, we break down the hardware alignment requirements, standard reference method selection, and the critical statistical calculations needed to pass your RATA. Key Metrics & Concepts Highlighted: • Calibration Drift (CD) Evaluation LESS THAN(2.5% of span requirement) • Relative Accuracy (RA) Criteria LESS THAN(20% of mean RM value or alternative limits) • Confidence Coefficient (CC) Math • Data Reduction and Outlier Handling If you want more technical guides on clean air compliance, CEMS engineering, stack testing QA/QC, or QSTI prep tutorials, make sure to subscribe to the channel! #EPAPS2 #CEMS #RATA #StackTesting #EnvironmentalCompliance #AirEmissions #SO2 #NOx #ContinuousEmissions #QSTI
