Sec. 60.104  Standards for sulfur oxides.

    Each owner or operator that is subject to the requirements of this 
subpart shall comply with the emission limitations set forth in this 
section on and after the date on which the initial performance test, 
required by Sec. 60.8, is completed, but not later than 60 days

[[Page 318]]

after achieving the maximum production rate at which the affected 
facility will be operated, or 180 days after initial startup, whichever 
comes first.
    (a) No owner or operator subject to the provisions of this subpart 
shall:
    (1) Burn in any fuel gas combustion device any fuel gas that 
contains hydrogen sulfide (H2S) in excess of 230 mg/dscm 
(0.10 gr/dscf). The combustion in a flare of process upset gases or fuel 
gas that is released to the flare as a result of relief valve leakage or 
other emergency malfunctions is exempt from this paragraph.
    (2) Discharge or cause the discharge of any gases into the 
atmosphere from any Claus sulfur recovery plant containing in excess of:
    (i) For an oxidation control system or a reduction control system 
followed by incineration, 250 ppm by volume (dry basis) of sulfur 
dioxide (SO2) at zero percent excess air.
    (ii) For a reduction control system not followed by incineration, 
300 ppm by volume of reduced sulfur compounds and 10 ppm by volume of 
hydrogen sulfide (H2S), each calculated as ppm SO2 
by volume (dry basis) at zero percent excess air.
    (b) Each owner or operator that is subject to the provisions of this 
subpart shall comply with one of the following conditions for each 
affected fluid catalytic cracking unit catalyst regenerator:
    (1) With an add-on control device, reduce SO2 emissions 
to the atmosphere by 90 percent or maintain SO2 emissions to 
the atmosphere less than or equal to 50 ppm by volume (ppmv), whichever 
is less stringent; or
    (2) Without the use of an add-on control device to reduce 
SO2 emission, maintain sulfur oxides emissions calculated as 
SO2 to the atmosphere less than or equal to 9.8 kg/Mg (20 lb/
ton) coke burn-off; or
    (3) Process in the fluid catalytic cracking unit fresh feed that has 
a total sulfur content no greater than 0.30 percent by weight.
    (c) Compliance with paragraph (b)(1), (b)(2), or (b)(3) of this 
section is determined daily on a 7-day rolling average basis using the 
appropriate procedures outlined in Sec. 60.106.
    (d) A minimum of 22 valid days of data shall be obtained every 30 
rolling successive calendar days when complying with paragraph (b)(1) of 
this section.
