33:III.2108.C.3 the following reference methods shall be used:
      a.  for the determination of volume at the exhaust vent:

AQ145   §2108.E.1.a.i;LAd34 LA021.02;AQ145;LR22:1212p7(12/20/1996)
            i. Method 2B (40 CFR part 60, appendix A, as incorporated 
by reference at LAC 33.III.3003) for combustion vapor processing 
systems (except flare stacks).

AQ145   §2108.E.1.a.ii;LAd34;LA021.02;AQ145;LR22:1212p7(12/20/1996)
            ii. Method 2A (40 CFR part 60, appendix A, as incorporated 
by reference at LAC 33:III.3003) for all other vapor processing systems.

AQ145   §2108.E.1.b;LAd34;LA021.02;AQ145;LR22:1212p7(12/20/1996)
         b. for the determination of total organic compounds concentration at 
the exhaust vent, Method 25A or 25B (40 CFR part 60, appendix A, as 
incorporated by reference at LAC 33:III.3003). The calibration gas shall 
be either propane or butane.

AQ171*   §2108.E.2;LAd34;LA021.05;AQ171*;LR24:1285(7/20/1998)
      2. Vapor processing systems utilizing a flare stack to 
destruct the collected VOCs will be exempt from testing and 
must be designed and operated in accordance with 40 CFR 
60.482-10(d), as incorporated by reference in 
LAC 33:III.Chapter 30.

AQ145   §2108.E.3;LAd34;LA021.02;AQ145;LR22:1212p7(12/20/1996)
      3. Immediately prior to the performance test for determination of 
compliance, all potential sources of vapor leakage in the faci1ity’s vapor 
collection system equipment shall be monitored for leaks using Method 21 
(40 CFR part 60, appendix A, as incorporated by reference at LAC 33:III.3003). 
The monitoring shall be conducted only while a ship or barge is being loaded 
and should cover all parts of the vapor system, including tank hatches, that 
operate at pressures above atmospheric pressure. All leaks shall be repaired prior 
to conducting the performance test.

    4.  The test procedure for determining compliance with LAC 33:III.2108.C.3 shall be that 
specified below:
      a.  All testing equipment shall be prepared and installed as specified in the appropriate test methods.
      b.  The time period for a performance test shall be not less than three hours.  As much as possible, testing should be conducted during the three-hour period in which the highest emissions normally occur (near the end of the loading).
      c.  For intermittent vapor processing systems:
        i.  the vapor holder level shall be recorded at the start of the performance test.  The end of the performance test shall coincide with a time when the vapor holder is at its original level;
        ii.  at least two startups and shutdowns of the vapor processor shall occur during the performance test.  If this does not occur under automatically-controlled operation, the system shall be manually controlled.
      d.  The volume of crude oil, gasoline and volatile organic compounds loaded during the performance test period, whose vapor emissions are controlled by the processing system being tested, shall be determined.
      e.  An emission testing interval shall consist of each five-minute period during the performance test.  For each interval:
        i.  the reading from each measurement instrument shall be recorded, and
        ii.  the volume exhausted and the average total organic compounds concentration in the exhaust vent shall be determined, as specified in the appropriate test method.  The average  total organic compounds concentration shall correspond to the volume measurement by taking into account the sampling system response time.
      f.  The mass emitted during each testing interval shall be calculated as follows:

  Mei = (10^-6)(K)(Ves)(Ce)

  where:
    Mei = mass of total organic compounds emitted during testing interval i, mg.
    Ves = volume of air-vapor mixture exhausted, m^3, at standard conditions.
    Ce = total organic compounds concentration (as measured) at the exhaust vent, ppmv.
    K = density of calibration gas, mg/m^3, at standard conditions.
      = 1.83 x 10^6 for propane
      = 2.41 x 10^6 for butane.
    s = standard conditions, 20 degrees C and 760 mm Hg.


      g.  The total organic compounds mass emissions shall be
calculated as follows:

      Sum from i = 1 to n {Mei}
  E = --------------------------
               L
  where:
    E = mass of total organic compounds emitted per volume of crude oil, gasoline and volatile organic compounds loaded, mg./liter.
    Mei = mass of total organic compounds emitted during testing interval i, mg.
    L = total volume of crude oil, gasoline and volatile organic compounds loaded, liters.
    n = number of testing intervals.

AQ145   §2108.E.5;LAd34;LA021.02;AQ145;LR22:1212p7(12/20/1996)
      5. The owner or operator may adjust the emission results to exclude 
the methane and ethane content in the exhaust vent by the chromatographic 
method shown in Method 25 (40 CFR part 60, appendix A, as incorporated by 
reference at LAC III.3003).
