(a) Except as provided in paragraph (b) of this section, you must conduct an initial performance test, as required under § 60.8, to determine compliance with the emission limitations in table 2 or 2a to this subpart and to establish operating limits using the procedures in § 60.3023 or § 60.3024. The initial performance test must be conducted using the test methods listed in table 2 or 2a to this subpart and the procedures in § 60.3027. In the event of any conflict between § 60.8 and the provisions of this subpart, the provisions of this subpart shall apply.

(b) For very small municipal waste combustion units and institutional waste incineration units with a capacity less than or equal to 10 tons per day, you must demonstrate initial compliance according to paragraph (a) of this section, unless you comply with the requirements for the substitute means of compliance demonstration requirements in § 60.3032.

(c) For each OSWI unit with a capacity greater than 10 tons per day, as an alternative to conducting a performance test under paragraph (a) of this section for carbon monoxide, you may use a 12-hour rolling average of the 1-hour arithmetic average CEMS data to determine compliance with the emission limitations in tables 2 and 2a to this subpart. The initial performance evaluation required by § 60.3039(b) must be conducted prior to collecting CEMS data that will be used for the initial compliance demonstration.
