Texas SIP: 30 TAC 112.6: Allowable Emission Rates—Sulfuric Acid Plant

Regulatory Text: 
Section 112.6.  Allowable Emission Rates - Sulfuric Acid Plant.

(Approved by EPA 08/30/93 (58 FR 45457) at 52.2270(c)(76) effective 10/29/93.)

   (a) Except as provided in Section 112.5 of this title (relating to Allowable Emission Rates - Sulfuric Acid Plant Burning Elemental Sulfur), and in Section 112.14 of this title (relating to Allowable Emission Rates - Nonferrous Smelter Processes), no person may cause, suffer, allow, or permit emissions of sulfur dioxide (SO2) from any sulfuric acid plant to exceed the emission limits specified by the equation:

E = 0.0347 q

Where:
E = allowable emission rate in pounds per hour
q = stack effluent rate in standard cubic feet per minute (scfm)


   (b) If a source has an effective stack height less than the standard effective stack height determined by the equation:

He = 1.17 q^0.5

Where:
He = standard effective stack height in feet
q = the stack effluent flow rate in scfm

then, the allowable emission limit in subsection (a) of this section must be reduced by multiplying it by the short-stack reduction factor.

   (c) Beginning September 30, 1994, sulfuric acid plants of greater than 300 tons per day production capacity, with production expressed as 100% acid, and to which this section applies, shall be equipped with a continuous emissions monitoring system (CEMS) for SO2.  The CEMS shall be installed, calibrated, and operated as specified in 40 CFR Part 51, Appendix P, hereby incorporated by reference. 

As adopted by TACB 09/18/92 effective 10/23/92
