Issues Concerning the Use of Precision and Accuracy Data. Special Report

摘要

This report represents the efforts of the Work Group on the Utilization of Precision and Accuracy (P&A) data, which was formed to determine how P&A data should be utilized relative to the EPA regulatory decision-making process. The report discusses ten issues concerning the utilization of P&A data and summarizes the calculations specified in 40 CFR 58 Appendix A, 'Quality Assurance Requirements for State and Local Air Monitoring Stations (SLAMS).' P&A data is reported by the National Aerometric Data Bank (NADB), along with the associated air quality. The P&A data bank is maintained by the Environmental Monitoring Systems Laboratory (EMSL) and contains the P&A data reported by the States to the EPA Regional offices and EMSL.
