Sec. 60.154  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 as 
specified in this section, except as provided for in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter emission standards in Sec. 60.152 as follows:
    (1) The emission rate (E) of particulate matter for each run shall 
be computed using the following equation:

[[Page 380]]

[GRAPHIC] [TIFF OMITTED] TR17OC00.005

Where:

E = Emission rate of particulate matter, g/kg (lb/ton) of dry sludge 
input.
cs = Concentration of particulate matter, g/dscm (gr/dscf).
Qsd = Volumetric flow rate of effluent gas, dscm/hr (dscf/
hr).
S = Charging rate of dry sludge during the run, kg/hr (ton/hr).
K = Conversion factor, 1.0 g/g (7,000 gr/lb).

    (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 for each run shall be at least 60 minutes and 0.90 dscm (31.8 
dscf).
    (3) The dry sludge charging rate (S) for each run shall be computed 
using either of the following equations:
[GRAPHIC] [TIFF OMITTED] TR17OC00.006

Where:

S = Charging rate of dry sludge, kg/hr (ton/hr).
Sm = Total mass of sludge charge, kg (ton).
Rdm = Average mass of dry sludge per unit mass of sludge 
charged, kg/kg (ton/ton).
[thetas] = Duration of run, hr.
Sv = Total volume of sludge charged, m\3\ (gal).
Rdv = Average mass of dry sludge per unit volume of sludge 
charged, kg/m\3\ (lb/gal).
Kv = Conversion factor, 1 g/g (2,000 lb/ton).

    (4) the flow measuring device of Sec. 60.153(a)(1) shall be used to 
determine the total mass (Sm) or volume (Sv) of 
sludge charged to the incinerator during each run. If the flow measuring 
device is on a time rate basis, readings shall be taken and recorded at 
5-minute intervals during the run and the total charge of sludge shall 
be computed using the following equations, as applicable:
[GRAPHIC] [TIFF OMITTED] TR17OC00.007

[GRAPHIC] [TIFF OMITTED] TR17OC00.008

Where:

Sm = Total mass of sludge charged to the incinerator during 
the test run.
Sv = Total volume of sludge charged to the incinerator during 
the test run.
Qmi = Average mass flow rate calculated by averaging the flow 
rates at the beginning and end of each interval ``i,'' kg/hr (ton/hr).
Qvi = Average volume flow rate calculated by averaging the 
flow rates at the beginning and end of each interval ``i,'' m\3\/hr 
(gal/hr).
[thetas]i = Duration of interval ``i,'' hr.

    (5) Samples of the sludge charged to the incinerator shall be 
collected in nonporous jars at the beginning of each run and at 
approximately 1-hour intervals thereafter until the test ends, and ``209 
F. Method for Solid and Semisolid Samples'' (incorporated by reference--
see Sec. 60.17) shall be used to determine dry sludge content of each 
sample (total solids residue), except that:
    (i) Evaporating dishes shall be ignited to at least 103 [deg]C 
rather than the 550 [deg]C specified in step 3(a)(1).
    (ii) Determination of volatile residue, step 3(b) may be deleted.
    (iii) The quantity of dry sludge per unit sludge charged shall be 
determined in terms of kg/m\3\ (lb/gal) or kg/kg (ton/ton).
    (iv) The average dry sludge content shall be the arithmetic average 
of all the samples taken during the run.
    (6) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity.
    (c) [Reserved]
    (d) The owner or operator of any sludge incinerator subject to the 
provisions of this subpart shall conduct a performance test during which 
the monitoring and recording devices required under Sec. 60.153(a)(1), 
(b)(1), (b)(2), (b)(3), and (b)(4) are installed and operating and for 
which the sampling and analysis procedures required under Sec. 
60.153(b)(5) are performed. The owner or operator shall provide the 
Administrator at least 30 days prior notice of the performance test to 
afford the Administrator the opportunity to have an observer present.
    (1) For incinerators that commenced construction or modification on 
or before April 18, 1986, the performance test shall be conducted within 
360 days of the effective date of these regulations unless the 
monitoring and recording devices required under Sec. 60.153(a)(1),

[[Page 381]]

(b)(1), (b)(2), (b)(3), and (b)(4) were installed and operating and the 
sampling and analysis procedures required under Sec. 60.153(b)(5) were 
performed during the most recent performance test and a record of the 
measurements taken during the performance test is available.
    (2) For incinerators that commence construction or modification 
after April 18, 1986, the date of the performance test shall be 
determined by the requirements in Sec. 60.8.
