Sec.  63.1325  Batch process vents--performance test methods and 

procedures to determine compliance.

    (a) Use of a flare. When a flare is used to comply with Sec.  
63.1322(a)(1), Sec.  63.1322(a)(3), Sec.  63.1322(b)(1), or Sec.  
63.1322(b)(3), the owner or operator of an affected source shall comply 
with Sec.  63.1333(e).
    (b) Exceptions to performance tests. An owner or operator is not 
required to conduct a performance test when a control device specified 
in paragraphs (b)(1) through (b)(5) of this section is used to comply 
with Sec.  63.1322(a)(2) or (a)(3).
    (1) A boiler or process heater with a design heat input capacity of 
44 megawatts or greater.
    (2) A boiler or process heater where the vent stream is introduced 
with the primary fuel or is used as the primary fuel.
    (3) A control device for which a performance test was conducted for 
determining compliance with a regulation promulgated by the EPA and the 
test was conducted using the same Methods specified in this section and 
either no deliberate process changes have been made since the test, or 
the owner or operator can demonstrate that the results of the 
performance test, with or without adjustments, reliably demonstrate 
compliance despite process changes. Recovery devices used for 
controlling emissions from continuous process vents complying with Sec.  
63.1322(a)(3) are also eligible for the

[[Page 332]]

exemption described in this paragraph (b)(3).
    (4) A boiler or process heater burning hazardous waste for which the 
owner or operator:
    (i) Has been issued a final permit under 40 CFR part 270 and 
complies with the requirements of 40 CFR part 266, subpart H; or
    (ii) Has certified compliance with the interim status requirements 
of 40 CFR part 266, subpart H.
    (5) A hazardous waste incinerator for which the owner or operator 
has been issued a final permit under 40 CFR part 270 and complies with 
the requirements of 40 CFR part 264, subpart O, or has certified 
compliance with the interim status requirements of 40 CFR part 265, 
subpart O.
    (c) Batch process vent testing and procedures for compliance with 
Sec.  63.1322(a)(2). Except as provided in paragraph (a) or (b) of this 
section, an owner or operator using a control device to comply with 
Sec.  63.1322(a)(2) shall conduct a performance test using the 
procedures specified in paragraph (c)(1) of this section in order to 
determine the control efficiency of the control device. An owner or 
operator shall determine the percent reduction for the batch cycle using 
the control efficiency of the control device as specified in paragraphs 
(c)(2)(i) through (c)(2)(iii) of this section and the procedures 
specified in paragraph (c)(2) of this section. Compliance may be based 
on either total organic HAP or TOC. For purposes of this paragraph (c), 
the term ``batch emission episode'' shall have the meaning ``period of 
the batch emission episode selected for control,'' which may be the 
entire batch emission episode or may only be a portion of the batch 
emission episode.
    (1) Performance tests shall be conducted as specified in paragraphs 
(c)(1)(i) through (c)(1)(v) of this section.
    (i) Except as specified in paragraph (c)(1)(i)(A) of this section, a 
test shall be performed for the entire period of each batch emission 
episode in the batch cycle that the owner or operator selects to control 
as part of achieving the required 90 percent emission reduction for the 
batch cycle specified in Sec.  63.1322(a)(2). Only one test is required 
for each batch emission episode selected by the owner or operator for 
control. The owner or operator shall follow the procedures listed in 
paragraphs (c)(1)(i)(B) through (c)(1)(i)(D) of this section.
    (A) Alternatively, an owner or operator may choose to test only 
those periods of the batch emission episode during which the emission 
rate for the entire episode can be determined or during which the 
emissions are greater than the average emission rate of the batch 
emission episode. The owner or operator choosing either of these options 
shall develop an emission profile for the entire batch emission episode, 
based on either process knowledge or test data collected, to demonstrate 
that test periods are representative. Examples of information that could 
constitute process knowledge include calculations based on material 
balances and process stoichiometry. Previous test results may be used 
provided the results are still relevant to the current batch process 
vent conditions.
    (B) Method 1 or 1A, 40 CFR part 60, appendix A, as appropriate, 
shall be used for selection of the sampling sites if the flow measuring 
device is a pitot tube, except that references to particulate matter in 
Method 1A do not apply for the purposes of this subpart. No traverse is 
necessary when Method 2A or 2D, 40 CFR part 60, appendix A is used to 
determine gas stream volumetric flow rate. Inlet sampling sites shall be 
located as specified in paragraphs (c)(1)(i)(B)(1) and (c)(1)(i)(B)(2) 
of this section. Outlet sampling sites shall be located at the outlet of 
the control device prior to release to the atmosphere.
    (1) The control device inlet sampling site shall be located at the 
exit from the batch unit operation before any control device. Sec.  
63.1323(a)(2) describes those recovery devices considered part of the 
unit operation. Inlet sampling sites would be after these specified 
recovery devices.
    (2) If a batch process vent is introduced with the combustion air or 
as a secondary fuel into a boiler or process heater with a design 
capacity less than 44 megawatts, selection of the location of the inlet 
sampling sites shall ensure the measurement of total organic HAP or TOC 
(minus methane and ethane) concentrations in all batch process

[[Page 333]]

vents and primary and secondary fuels introduced into the boiler or 
process heater.
    (C) Gas stream volumetric flow rate and/or average batch vent flow 
rate shall be determined as specified in Sec.  63.1323(e).
    (D) Method 18 or Method 25A, 40 CFR part 60, appendix A shall be 
used to determine the concentration of organic HAP or TOC, as 
appropriate. Alternatively, any other method or data that has been 
validated according to the applicable procedures in Method 301 of 
appendix A of this part may be used. The use of Method 25A, 40 CFR part 
60, appendix A shall conform with the requirements in paragraphs 
(c)(1)(i)(D)(1) and (c)(1)(i)(D)(2) of this section.
    (1) The organic HAP used as the calibration gas for Method 25A, 40 
CFR part 60, appendix A shall be the single organic HAP representing the 
largest percent by volume of the emissions.
    (2) The use of Method 25A, 40 CFR part 60, appendix A is acceptable 
if the response from the high-level calibration gas is at least 20 times 
the standard deviation of the response from the zero calibration gas 
when the instrument is zeroed on the most sensitive scale.
    (ii) If an integrated sample is taken over the entire test period to 
determine average batch vent concentration of TOC or total organic HAP, 
emissions per batch emission episode shall be calculated using Equations 
19 and 20 of this subpart.

least 20 times the standard deviation of the response from the zero 
calibration gas when the instrument is zeroed on the most sensitive 
scale.
    (2) When Sec.  63.116(c)(4) refers to complying with an emission 
reduction of 98 percent, for purposes of this subpart, the 90 percent 
reduction requirement specified in Sec.  63.1322(b)(2) shall apply.

performance testing procedures of Sec.  63.116(c)(3) and Sec.  
63.116(c)(3)(iii) is only required when supplemental combustion air is 
used to combust the emissions, for the purposes of this subpart.
    (f) Compliance with Sec.  63.1322(a)(3) [new SAN batch affected 
sources]. Except as provided in paragraph (b) of this section, an owner 
or operator using a control or recovery device to comply with the 
percent reduction requirement in Sec.  63.1322(a)(3) shall conduct 
performance tests as specified in either paragraph (f)(1), (f)(2), or 
(f)(3) of this section, as applicable. Compliance with Sec.  
63.1322(a)(3) shall be determined as specified in paragraph (f)(4) of 
this section.
    (1) For batch process vents, performance tests shall be conducted 
using the procedures specified in paragraph (c) of this section, except 
that the owner or operator is not required to determine the percent 
reduction for the batch cycle as specified in paragraph (c)(2) of this 
section.
    (2) For continuous process vents, performance tests shall be 
conducted as required by the applicable requirements of Sec.  63.1315(a) 
as specified in Sec.  63.1321(b).
    (3) For aggregate batch vent streams, performance tests shall be 
conducted as specified in paragraph (e) of this section.
    (4) Compliance with the percent reduction requirement of Sec.  
63.1322(a)(3) shall be demonstrated using the procedures specified in 
Sec.  63.1333(c) and the control device efficiencies specified in either 
paragraph (f)(4)(i) or (f)(4)(ii) of this section. Emissions for 
uncontrolled continuous process vents and aggregate batch vent streams 
shall be determined based on the direct measurement procedures specified 
in paragraph (f)(2) and (f)(3) of this section, respectively, or based 
on engineering assessment, as specified in Sec.  63.1323(b)(6)(i). At 
the discretion of the owner or operator, emissions for uncontrolled 
batch process vents shall be determined based on any of the procedures 
in Sec.  63.1323(b).
    (i) For noncombustion devices, the control efficiency shall be as 
determined by the performance test required by paragraph (f)(1), (f)(2), 
or (f)(3) of

[[Page 337]]

this section. Alternatively, if a performance test is not required by 
paragraph (c) of this section, the control efficiency shall be 
determined by the owner or operator based on engineering assessment.
    (ii) For combustion devices, the control efficiency shall be as 
determined by the performance test required by paragraph (f)(1), (f)(2), 
or (f)(3) of this section. Alternatively, if a performance test is not 
required, the control efficiency shall be 98 percent. The control 
efficiency for a flare shall be 98 percent.
    (g) Batch mass input limitation. The batch mass input limitation 
required by Sec.  63.1322(g)(1) shall be determined by the owner or 
operator such that annual emissions for the batch process vent remain 
less than the level specified in Sec.  63.1323(d). The batch mass input 
limitation required by Sec.  63.1322(f)(1) shall be determined by the 
owner or operator such that annual emissions remain at a level that 
ensures that said batch process vent remains a Group 2 batch process 
vent, given the actual annual flow rate for said batch process vent 
determined according to the procedures specified in Sec.  63.1323(e)(3). 
The batch mass input limitation shall be determined using the same 
basis, as described in Sec.  63.1323(a)(1), used to make the group 
determination (i.e., expected mix of products or highest-HAP recipe.) 
The establishment of the batch mass input limitation is not dependent 
upon any past production or activity level.
    (1) If the expected mix of products serves as the basis for the 
batch mass input limitation, the batch mass input limitation shall be 
determined based on any foreseeable combination of products that the 
owner or operator expects to manufacture.
    (2) If the single highest-HAP recipe serves as the basis for the 
batch mass input limitation, the batch mass input limitation shall be 
determined based solely on the production of the single highest-HAP 
recipe, considering all products produced or processed in the batch unit 
operation.
