A. Start-up Provisions
1. A four-hour (continuous) start-up exemption from the emission limitations of LAC 33:III.1503.A may be authorized by the administrative authority for plants not subject to LAC 33:III.3232 and 3233 which have been shut down. A report in writing explaining the conditions and duration of the start-up and listing the steps necessary to remedy, prevent and limit the excess emission shall be submitted to the administrative authority within seven calendar days of the occurrence.
2. This provision is applicable to infrequent start-ups only. Before the exemption can be granted the administrative authority must determine the excess emissions were not the result of failure to maintain or repair equipment. In addition the duration of excess emission must be minimized and no ambient air quality standard may be jeopardized.
B. On-Line Operating Adjustments
1. A four-hour (continuous) exemption from emission limitations of LAC 33:III.1503.A may be extended by the administrative authority to plants not subject to LAC 33:III.3232 and 3233 where upsets have caused excessive emissions and on-line operating changes will eliminate a temporary condition. A report, in writing, explaining the conditions and duration of the upset and listing the steps necessary to remedy, prevent and limit the excess emission shall be submitted to the administrative authority within seven calendar days of the occurrence.
