(a)Conduct initial, daily, quarterly, and annual evaluations of your continuous emission monitoring systems that measure carbon monoxide and oxygen.
(b)Complete your initial performance evaluation of the continuous emission monitoring systems within 60 days after your OSWI unit reaches the maximum load level at which it will operate, but no later than 180 days after its initial startup.
(c)For initial and annual performance 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 EPA Method 10, 10A, or 10B of Appendix A to this part. Use EPA Method 3A or 3B of Appendix A to this part or ASME/ANSI PTC 19.10-1981 (incorporated by reference, see § 60.17), in lieu of Method 3B, to measure oxygen. Collect the data during each initial and annual evaluation of your continuous emission monitoring systems following the applicable performance specifications in Appendix B to this part. Table 3 to this subpart 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 appendix F of this part for each continuous emission monitoring system. The procedures include daily calibration drift and quarterly accuracy determinations. [70 FR 74892, Dec. 16, 2005, as amended at 90 FR 27945, June 30, 2025]
