   A. The emission of smoke from a flare or other similar

that the shade or appearance of the emission does not exceed
20 percent opacity (LAC 33:III.1503.D.2, Table 4) for a
combined total of six hours in any 10 consecutive days. If it
appears the emergency cannot be controlled in six hours,
SPOC shall be notified by the emitter in accordance with

authority will automatically grant an exemption to the
source(s) of excessive emissions.
