| (a) Conduct initial, daily, quarterly, and annual evaluations of your continuous emission monitoring systems that measure carbon monoxide and oxygen. (b) Complete your initial evaluation of the continuous emission monitoring systems within 180 days after your final compliance date in Table 1 in §113.2357 of this title (relating to Tables Relating to Division 5). (c) For initial and annual evaluations, collect data concurrently (or within 30 to 60 minutes) using your carbon monoxide and oxygen continuous emission monitoring systems. To validate carbon monoxide concentration levels, use United States Environmental Protection Agency (EPA) Method 10, 10A, or 10B of 40 Code of Federal Regulations (CFR) Part 60, Appendix A. Use EPA Method 3 or 3A of 40 CFR Part 60, Appendix A to measure oxygen. Collect the data during each initial and annual evaluation of your continuous emission monitoring systems following the applicable performance specifications in 40 CFR Part 60, Appendix B. Table 4 in §113.2357 of this title shows the required span values and performance specifications that apply to each continuous emission monitoring system. (d) Follow the quality assurance procedures in Procedure 1 of 40 CFR Part 60, Appendix F for each continuous emission monitoring system. The procedures include daily calibration drift and quarterly accuracy determinations. |
