§111.151.  Allowable Emissions Limits.
1-07: As adopted by TACB June 16, 1989 effective July 18, 1989 (1-07).
Approved by EPA April 28, 2009 (74 FR 19144) effective May 28, 2009 (TXd103).

      (a)  No person may cause, suffer, allow, or permit emissions of particulate matter from any source to exceed the allowable rates specified in Table 1 as follows, except as provided by §111.153 of this title (relating to Emissions Limits for Steam Generators).

      (b)  If a source has an effective stack height less than the standard effective stack height as determined from Table 2 as follows, the allowable emission level must be reduced by multiplying it by:

                      Effective Stack Height 
               (---------------------------------)²
                 Standard Effective Stack Height 

      (c)  Effective stack height shall be calculated by the following equation:

                              T_e - 550
h_e = h + 0.83v_eD_e[1.5 + 0.82(----------)D_e]
                                  T_e 

Where:

    h_e = Effective stack height in feet (ft)
    h  = Physical stack height above ground level in feet (ft)
    v_e = Stack exit velocity in feet per second (ft/sec) 
    D_e = Stack exit inside diameter in feet (ft) 
    T_e = Stack exit temperature in degrees Rankine (ER)



TABLE 1.  ALLOWABLE PARTICULATE EMISSION RATES FOR SPECIFIC FLOW RATES
 

Interpolation and extrapolation of the data in this table shall be accomplished by the use of the equation E = 0.048(q^0.62)  for total suspended particulate (TSP) where E is the allowable emis­sion rate in pounds per hour (lb/hr) and q is the stack effluent flow rate in actu­al cubic feet per minute (acfm).


TABLE 2.  STANDARD EFFECTIVE STACK HEIGHT BASED ON SPECIFIC FLOW RATES
 

Interpolation and extrapolation of the data in this table shall be accomplished by the use of the equation H_e = 1.05(q^0.35) where H_e is the standard effective stack height in feet and q is the stack efflu­ent flow rate in acfm.


Adopted June 16, 1989, Effective July 18, 1989 (1-07).

§111.153.  Emissions Limits for Steam Generators.
1-07: As adopted by TACB June 16, 1989 effective July 18, 1989 (1-07).
Approved by EPA April 28, 2009 (74 FR 19144) effective May 28, 2009 (TXd103).

      (a)  Section 111.151 of this title (relating to Allow­able Emis­sions Limits) shall not apply to any oil or gas fuel-fired steam gen­erator with a heat input greater than 2500 million British thermal units per hour or any solid fossil fuel-fired steam generator.

      (b)  No person may cause, suffer, allow, or permit emis­sions of particulate matter from any solid fossil fuel-fired steam generator to exceed 0.3 pound of total suspended particu­late per million Btu heat input, averaged over a two-hour period.

      (c)  No person may cause, suffer, allow or permit emissions of particu­late matter from any oil or gas fuel-fired steam gen­erator with a heat input greater than 2500 million Btu per hour to exceed 0.1 pound of total suspended particulate per million Btu input averaged over a two-hour period.

Adopted June 16, 1989, Effective July 18, 1989 (1-07).
