Chapter 13. Emission Standards for Particulate Matter

Subchapter B. Fluid Catalytic Cracking Units

Outline:
Section 1311.  Emission Limits-Including Fluid Catalytic Cracking Units


Section 1311.  Emission Limits-Including Fluid Catalytic Cracking Units
Approved by EPA 03/08/89 (54 FR 09795) at 52.970(c)(49) effective 05/08/89.  Revisions approved by EPA 06/15/89 at 52.970(c)(50) effective 08/14/89.

   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 new or existing fluid catalytic cracking unit incinerator waste heat boilers shall be controlled so that the shade or appearance of the emission is not denser than 20 percent average opacity (see Table 4); except that emitted may have an average opacity in excess of 20 percent for not more than one six minute period in any 60 consecutive minutes.

   D.  For new or existing fluid catalytic cracking unit incinerator waste heat boilers emissions shall not exceed 30 percent average opacity (see Table 4) except that emitted may be denser than 30 percent average opacity for not more than one six minute period in any 60 consecutive minutes.

   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.
