Sec. 60.285  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures in 
this section, except as provided in Sec. 60.8(b). Acceptable 
alternative methods and procedures are given in paragraph (f) of this 
section.
    (b) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.282(a) (1) and (3) as follows:
    (1) Method 5 shall be used to determine the particulate matter 
concentration. The sampling time and sample volume for each run shall be 
at least 60 minutes and 0.90 dscm (31.8 dscf). Water shall be used as 
the cleanup solvent instead of acetone in the sample recovery procedure. 
The particulate concentration shall be corrected to the appropriate 
oxygen concentration according to Sec. 60.284(c)(3).
    (2) The emission rate correction factor, integrated sampling and 
analysis procedure of Method 3B shall be used to determine the oxygen 
concentration. The gas sample shall be taken at the same time and at the 
same traverse points as the particulate sample.
    (3) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity.
    (c) The owner or operator shall determine compliance with the 
particular matter standard in Sec. 60.282(a)(2) as follows:
    (1) The emission rate (E) of particulate matter shall be computed 
for each run using the following equation:

E=cs Qsd/BLS

where:

E=emission rate of particulate matter, g/kg (lb/ton) of BLS.
cs = Concentration of particulate matter, g/dscm (lb/dscf).
Qsd=volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
BLS=black liquor solids (dry weight) feed rate, kg/hr (ton/hr).


[[Page 423]]


    (2) Method 5 shall be used to determine the particulate matter 
concentration (cs) and the volumetric flow rate 
(Qsd) of the effluent gas. The sampling time and sample 
volume shall be at least 60 minutes and 0.90 dscm (31.8 dscf). Water 
shall be used instead of acetone in the sample recovery.
    (3) Process data shall be used to determine the black liquor solids 
(BLS) feed rate on a dry weight basis.
    (d) The owner or operator shall determine compliance with the TRS 
standards in Sec. 60.283, except Sec. 60.283(a)(1)(vi) and (4), as 
follows:
    (1) Method 16 shall be used to determine the TRS concentration. The 
TRS concentration shall be corrected to the appropriate oxygen 
concentration using the procedure in Sec. 60.284(c)(3). The sampling 
time shall be at least 3 hours, but no longer than 6 hours.
    (2) The emission rate correction factor, integrated sampling and 
analysis procedure of Method 3B shall be used to determine the oxygen 
concentration. The sample shall be taken over the same time period as 
the TRS samples.
    (3) When determining whether a furnace is a straight kraft recovery 
furnace or a cross recovery furnace, TAPPI Method T.624 (incorporated by 
reference--see Sec. 60.17) shall be used to determine sodium sulfide, 
sodium hydroxide, and sodium carbonate. These determinations shall be 
made 3 times daily from the green liquor, and the daily average values 
shall be converted to sodium oxide (Na20) and substituted 
into the following equation to determine the green liquor sulfidity:

Where:

GLS=green liquor sulfidity, percent.
CNa2S=concentration of Na2S as Na2O, 
mg/liter (gr/gal).
CNaOH=concentration of NaOH as Na2O, mg/liter (gr/
gal).
CNa2CO3=concentration of Na2CO3 as 
Na2O, mg/liter (gr/gal).

    (e) The owner or operator shall determine compliance with the TRS 
standards in Sec. 60.283(a)(1)(vi) and (4) as follows:
    (1) The emission rate (E) of TRS shall be computed for each run 
using the following equation:

E=CTRS F Qsd/P

where:

E=emission rate of TRS, g/kg (lb/ton) of BLS or ADP.
CTRS=average combined concentration of TRS, ppm.
F = conversion factor, 0.001417 g H2S/m\3\-ppm (8.846 x 
10-8 lb H2S/ft\3\-ppm).
Qsd=volumetric flow rate of stack gas, dscm/hr (dscf/hr).
P=black liquor solids feed or pulp production rate, kg/hr (ton/hr).

    (2) Method 16 shall be used to determine the TRS concentration 
(CTRS).
    (3) Method 2 shall be used to determine the volumetric flow rate 
(Qsd) of the effluent gas.
    (4) Process data shall be used to determine the black liquor feed 
rate or the pulp production rate (P).
    (f) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:
    (1) For Method 5, Method 17 may be used if a constant value of 0.009 
g/dscm (0.004 gr/dscf) is added to the results of Method 17 and the 
stack temperature is no greater than 204 [deg]C (400 [deg]F).
    (2) In place of Method 16, Method 16A or 16B may be used.
