2. Permit holder shall comply with the following requirements of 30 TAC Chapter 111:
A. Visible emissions from stationary vents constructed on or before January 31, 1972, shall not exceed 30% opacity averaged over a six-minute period as required in 30 TAC § 111.111(a)(1)(A). Compliance with the visible emission standard of 30 TAC § 111.111(a)(1)(A) shall be determined as required in 30 TAC § 111.111(a)(1)(F)(ii) by Test Method 9 (40 CFR Part 60, Appendix A), or as required in 30 TAC § 111.111(a)(1)(F)(iii) by Alternate Method 1 to Method 9, Light Detection and Ranging (40 CFR Part 60, Appendix A), or other equivalent test method approved in accordance with 30 TAC § 111.111(a)(1)(F)(iv). The permit holder shall also comply with the following periodic monitoring requirement: For purposes of the annual compliance certification under 30 TAC § 122.146, the permit holder is required to conduct an observation of stationary vents once during each 12-month certification period. If liquid fuel is fired for a period greater than or equal to 24 consecutive hours, the permit holder shall conduct an observation of the stationary vent for each such period to determine if visible emissions are observed.

If visible emissions are not observed in either case above , the RO may certify that the source is in compliance with the applicable opacity requirement in 30 TAC § 111.111(a)(1) and (a)(1)(A). Documentation is not required for observations where no visible emissions are present. However, if visible emissions are present during either case, the permit holder shall either list this occurrence as a deviation on the next deviation report as required under 30 TAC § 122.145(2) or conduct the appropriate opacity test specified in 30 TAC § 111.111(a)(1)(F) to determine if the source is in compliance with the opacity requirements. If an opacity test is performed and the source is determined to be in compliance, the RO may certify that the source is in compliance with the applicable opacity requirement. However, if an opacity test is performed and the source is determined to be out of compliance, the permit holder shall list this occurrence as a deviation on the next deviation report as required under 30 TAC § 122.145(2).
Visible emissions shall be determined with all sources in clear view of the observer. The observer shall be at least 15 feet, but not more than 0.25 miles, away from the emission source during the observation. For outdoor locations, the observer shall select a position where the sun is not directly in the observer’s eyes. Documentation is not required for observations where no visible emissions are present.
B. Visible emissions from stationary vents constructed after January 31, 1972, shall not exceed 20% opacity averaged over a six-minute period as required in 30 TAC § 111.111(a)(1)(B). Compliance with the visible emission standard of 30 TAC § 111.111(a)(1)(B) shall be determined as required in 30 TAC § 111.111(a)(1)(F)(ii) by Test Method 9 (40 CFR Part 60, Appendix A), or as required in 30 TAC § 111.111(a)(1)(F)(iii) by Alternate Method 1 to Method 9,

Light Detection and Ranging (40 CFR Part 60, Appendix A), or other equivalent test method approved in accordance with 30 TAC § 111.111(a)(1)(F)(iv). The permit holder shall also comply with the following periodic monitoring requirement:>469e23ed.000
