PART 63_NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR 

SOURCE CATEGORIES--Table of Contents

 

Subpart UUU_National Emission Standards for Hazardous Air Pollutants for 

  Petroleum Refineries: Catalytic Cracking Units, Catalytic Reforming 

                    Units, and Sulfur Recovery Units

 

Sec.  63.1562  What parts of my plant are covered by this subpart?



    (a) This subpart applies to each new, reconstructed, or existing 

affected source at a petroleum refinery.

    (b) The affected sources are:

    (1) The process vent or group of process vents on fluidized 

catalytic cracking units that are associated with regeneration of the 

catalyst used in the unit (i.e., the catalyst regeneration flue gas 

vent).

    (2) The process vent or group of process vents on catalytic 

reforming units (including but not limited to semi-regenerative, cyclic, 

or continuous processes) that are associated with regeneration of the 

catalyst used in the unit. This affected source includes vents that are 

used during the unit depressurization, purging, coke burn, and catalyst 

rejuvenation.

    (3) The process vent or group of process vents on Claus or other 

types of sulfur recovery plant units or the tail gas treatment units 

serving sulfur recovery plants, that are associated with sulfur 

recovery.

    (4) Each bypass line serving a new, existing, or reconstructed 

catalytic cracking unit, catalytic reforming unit, or sulfur recovery 

unit. This means each vent system that contains a bypass line (e.g., 

ductwork) that could divert an affected vent stream away from a control 

device used to comply with the requirements of this subpart.

    (c) An affected source is a new affected source if you commence 

construction of the affected source after September 11, 1998, and you 

meet the applicability criteria in Sec.  63.1561 at the time you 

commenced construction.

    (d) Any affected source is reconstructed if you meet the criteria in 

Sec.  63.2.

    (e) An affected source is existing if it is not new or 

reconstructed.

    (f) This subpart does not apply to:

    (1) A thermal catalytic cracking unit.

    (2) A sulfur recovery unit that does not recover elemental sulfur or 

where the modified reaction is carried out in a water solution which 

contains a metal ion capable of oxidizing the sulfide ion to sulfur 

(e.g., the LO-CAT II process).

    (3) A redundant sulfur recovery unit not located at a petroleum 

refinery and used by the refinery only for emergency or maintenance 

backup.

    (4) Equipment associated with bypass lines such as low leg drains, 

high point bleed, analyzer vents, open-ended valves or lines, or 

pressure relief valves needed for safety reasons.

    (5) Gaseous streams routed to a fuel gas system.
