Unless otherwise indicated, paragraphs are as previously approved by EPA 03/08/89 (54 FR 09795) effective 05/08/89 (LAc49) and revisions approved by EPA 06/15/89 effective 08/14/89 (LAc50)
A. The process weight rate per hour referred to in this Section shall be based upon the normal operation maximum capacity of the equipment and if such normal maximum capacity should be increased by process or equipment changes, the new normal maximum capacity shall be used as the process weight in determining the allowable emissions.
B. No person shall cause, suffer, allow, or permit the emission of particulate matter to the atmosphere from any process or process equipment in excess of the amount shown in Table 3 for the process weight rate allocated to such source. The rate of emission shall be the total of all emission points from the source.
C. The emission of particulate matter from any source
other than sources covered under Subsection D of this Section
shall be controlled so that the shade or appearance of the
emission is not denser than 20 percent average opacity (see
Table 4, Chapter 15); except the emissions may have an
average opacity in excess of20 percent for not more than one
six-minute period in any 60 consecutive minutes,
D. Fluid Catalytic Cracking Units. No owner or operator
shall discharge or cause the discharge into the atmosphere
from any new or existing fluid catalytic cracking unit catalyst
regenerator gases exhibiting greater than 30 percent opacity,
except for one six-minute average opacity reading in any one-hour
E. Emissions already less than that allowed by the process weight rate limitation (Table 3) will be considered by the administrative authority for exemption from the above state opacity limitation.
F. When the presence of uncombined water is the only reason for failure of an emission to meet the requirements of this Section, this Section will not apply.
G. Variances. Where upon written application of the responsible person or persons the administrative authority finds that by reason of exceptional circumstances strict conformity with any provisions of these regulations would cause undue hardship, would be unreasonable, impractical or not feasible under the circumstances, the administrative authority may permit a variance from or consider a change in these regulations upon such conditions and with such time limitations as it may prescribe for prevention, control or abatement of air pollution in harmony with the intent of the Act. No variance may permit or authorize the maintenance of a nuisance or a danger to public health or safety.
