30 Tex. Admin. Code § 112.112 - Control Requirements
(a) Production
Units 1 and 2 together are prohibited from operating with only one furnace
on-line and Production Unit 3 is prohibited from operating with only one
furnace on-line. Affected sources in §
112.110 of this title (relating to
Applicably) may not exceed the following pounds per hour (lb/hr) sulfur dioxide
(SO2) limits based on the number of furnaces on-line in
Production Units 1 and 2 and in Production Unit 3:
(b) If during any block one-hour
period the number of furnaces on-line changes, the emission limit must be
determined by one of the following methods:
(1) the fewest number of furnaces on-line in
each production unit during any fraction of the hour; or
(2) the time-weighted average of all limits
applying during any fraction of the hour, calculated using the following
equation:
(c) The maximum
emission rate of SO2 allowed under this section during
any block one-hour period must be determined on a block one-hour
average.
(d) The emission cap
identified in §112.112(a) of this section is the maximum emission limit
that applies to the sum of the emissions from the Incinerator + HRSG (EPN 13A),
Flare 4 (EPN Flare 4), Dryer Stack Units Nos. 1 & 2 (EPN 7A), and Dryer
Stack Unit No. 1 (EPN 12A), and the subcap identified in §112.112(a) of
this section is the maximum emission limit that applies to the sum of the
emissions from Dryer Stack Units Nos. 1 & 2 (EPN 7A) and Dryer Stack Units
No. 3 (EPN 12A).
(e) Tail gas may
only be combusted in sources whose emissions are routed to the Incinerator +
HRSG (EPN 13A), Flare 4 (EPN Flare 4), Dryer Stack Units Nos. 1 & 2 (EPN
7A), and Dryer Stack Unit No. 1 (EPN 12A).
(f) Simultaneous operation of the Incinerator
+ HRSG (EPN 13A) and Flare 4 (EPN FLARE 4) during any block one-hour period is
prohibited.
(g) Sulfur or sulfur
containing compounds may not be routed to Flare 1 (EPN Flare-1), Flare 2 (EPN
Flare-2), or Flare 3 (EPN Flare-3) on or after the compliance date in §
112.118 of this title (relating to
Compliance Schedule).
(h) After
construction and commencement of operation, if authorized, Flare 4 (EPN FLARE
4) must have a stack height of 60.35 meters and must be located at Universal
Transverse Mercator (UTM) coordinates UTM East Meters 273185 and UTM North
Meters 3573987 in UTM Zone 14.
(i)
Incinerator + HRSG (EPN 13A) must have a stack height of 65.00 meters no later
than the compliance date in §
112.118 of this title (relating to
Compliance Schedules).
(j) The
owner or operator may request an alternate means of control under the
provisions of §
112.102(i) of
this title (relating to Control Requirements).
