| Abstract | This report summarizes the first year's audit results of Continuous Emission Monitoring Systems (CEMS) installed at scrubber-equipped power plants. The audits were conducted to support a draft quality assurance appendix for 40 CFR 60 entitled 'Quality Assurance Procedures for Gas CEMS Used for Compliance'. The procedures call for a quality performance audit of the CEMS using certified cylinder gas or reference method tests. Audit data have been collected for sulfur dioxide, nitrogen oxides, oxygen and carbon dioxide. EDC, Contraves, Lear Seigler and DuPont CEMS have been audited, with the results indicating the need for frequent audits with effective corrective action to be taken when excessive inaccuracies are measured. |
