Sec. 60.44c  Compliance and performance test methods and procedures for
sulfur dioxide.

    (a) Except as provided in paragraphs (g) and (h) of this section and 
Sec. 60.8(b), performance tests required under Sec. 60.8 shall be 
conducted following the procedures specified in paragraphs (b), (c), 
(d), (e), and (f) of this section, as applicable. Section 60.8(f) does 
not apply to this section. The 30-day notice required in Sec. 60.8(d) 
applies only to the initial performance test unless otherwise specified 
by the Administrator.
    (b) The initial performance test required under Sec. 60.8 shall be 
conducted over 30 consecutive operating days of the steam generating 
unit. Compliance with the percent reduction requirements and 
SO2 emission limits under Sec. 60.42c shall be determined 
using a 30-day average. The first operating day included in the initial 
performance test shall be scheduled within 30 days after achieving the 
maximum production rate at which the affect facility will be operated, 
but not later than 180 days after the initial startup of the facility. 
The steam generating unit load during the 30-day period does not have to 
be the maximum design heat input capacity, but must be representative of 
future operating conditions.
    (c) After the initial performance test required under paragraph (b) 
of this section and Sec. 60.8, compliance with the percent reduction 
requirements and SO2 emission limits under Sec. 60.42c is 
based on the average percent reduction and the average SO2 
emission rates for 30 consecutive steam generating unit operating days. 
A separate performance test is completed at the end of each steam 
generating unit operating day, and a new 30-day average percent 
reduction and SO2 emission rate are calculated to show 
compliance with the standard.
    (d) If only coal, only oil, or a mixture of coal and oil is 
combusted in an affected facility, the procedures in Method 19 of 
appendix A of this part are used to determine the hourly SO2 
emission rate (Eho) and the 30-day average SO2 
emission rate (Eao). The hourly averages used to compute the 
30-day averages are obtained from the CEMS. Method 19 of appendix A of 
this part shall be used to calculate Eao when using daily 
fuel sampling or Method 6B of appendix A of this part.
    (e) If coal, oil, or coal and oil are combusted with other fuels:
    (1) An adjusted Eho (Ehoo) is used in Equation 
19-19 of Method 19 of appendix A of this part to compute the adjusted 
Eao (Eaoo). The Ehoo is computed using 
the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.033

Where:

Ehoo = Adjusted Eho, ng/J (lb/MMBtu);
Eho = Hourly SO2 emission rate, ng/J (lb/MMBtu);

[[Page 225]]

Ew = SO2 concentration in fuels other than coal 
and oil combusted in the affected facility, as determined by fuel 
sampling and analysis procedures in Method 9 of appendix A of this part, 
ng/J (lb/MMBtu). The value Ew for each fuel lot is used for 
each hourly average during the time that the lot is being combusted. The 
owner or operator does not have to measure Ew if the owner or 
operator elects to assume Ew = 0.
Xk = Fraction of the total heat input from fuel combustion 
derived from coal and oil, as determined by applicable procedures in 
Method 19 of appendix A of this part.

    (2) The owner or operator of an affected facility that qualifies 
under the provisions of Sec. 60.42c(c) or (d) (where percent reduction 
is not required) does not have to measure the parameters Ew 
or Xk if the owner or operator of the affected facility 
elects to measure emission rates of the coal or oil using the fuel 
sampling and analysis procedures under Method 19 of appendix A of this 
part.
    (f) Affected facilities subject to the percent reduction 
requirements under Sec. 60.42c(a) or (b) shall determine compliance 
with the SO2 emission limits under Sec. 60.42c pursuant to 
paragraphs (d) or (e) of this section, and shall determine compliance 
with the percent reduction requirements using the following procedures:
    (1) If only coal is combusted, the percent of potential 
SO2 emission rate is computed using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.034

Where:

%Ps = Potential SO2 emission rate, in percent;
%Rg = SO2 removal efficiency of the control device 
as determined by Method 19 of appendix A of this part, in percent; and
%Rf = SO2 removal efficiency of fuel pretreatment 
as determined by Method 19 of appendix A of this part, in percent.

    (2) If coal, oil, or coal and oil are combusted with other fuels, 
the same procedures required in paragraph (f)(1) of this section are 
used, except as provided for in the following:
    (i) To compute the %Ps, an adjusted %Rg 
(%Rgo) is computed from Eaoo from paragraph (e)(1) 
of this section and an adjusted average SO2 inlet rate 
(Eaio) using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.035

Where:

%Rgo = Adjusted %Rg, in percent;
Eaoo = Adjusted Eao, ng/J (lb/MMBtu); and
Eaio = Adjusted average SO2 inlet rate, ng/J (lb/
MMBtu).

    (ii) To compute Eaio, an adjusted hourly SO2 
inlet rate (Ehio) is used. The Ehio is computed 
using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.036

Where:

Ehio = Adjusted Ehi, ng/J (lb/MMBtu);
Ehi = Hourly SO2 inlet rate, ng/J (lb/MMBtu);
Ew = SO2 concentration in fuels other than coal 
and oil combusted in the affected facility, as determined by fuel 
sampling and analysis procedures in Method 19 of appendix A of this 
part, ng/J (lb/MMBtu). The value Ew for each fuel lot is used 
for each hourly average during the time that the lot is being combusted. 
The owner or operator does not have to measure Ew if the 
owner or operator elects to assume Ew = 0; and
Xk = Fraction of the total heat input from fuel combustion 
derived from coal and oil, as determined by applicable procedures in 
Method 19 of appendix A of this part.

    (g) For oil-fired affected facilities where the owner or operator 
seeks to demonstrate compliance with the fuel oil sulfur limits under 
Sec. 60.42c based on shipment fuel sampling, the initial performance 
test shall consist of sampling and analyzing the oil in the initial tank 
of oil to be fired in the steam generating unit to demonstrate that the 
oil contains 0.5 weight percent sulfur or less. Thereafter, the owner or 
operator of the affected facility shall sample the oil in the fuel tank 
after each new shipment of oil is received, as described under Sec. 
60.46c(d)(2).
    (h) For affected facilities subject to Sec. 60.42c(h)(1), (2), or 
(3) where the owner or operator seeks to demonstrate compliance with the 
SO2 standards based on fuel supplier certification, the 
performance test shall consist of the certification from the fuel 
supplier, as described in Sec. 60.48c(f), as applicable.
    (i) The owner or operator of an affected facility seeking to 
demonstrate

[[Page 226]]

compliance with the SO2 standards under Sec. 60.42c(c)(2) 
shall demonstrate the maximum design heat input capacity of the steam 
generating unit by operating the steam generating unit at this capacity 
for 24 hours. This demonstration shall be made during the initial 
performance test, and a subsequent demonstration may be requested at any 
other time. If the demonstrated 24-hour average firing rate for the 
affected facility is less than the maximum design heat input capacity 
stated by the manufacturer of the affected facility, the demonstrated 
24-hour average firing rate shall be used to determine the annual 
capacity factor for the affected facility; otherwise, the maximum design 
heat input capacity provided by the manufacturer shall be used.
    (j) The owner or operator of an affected facility shall use all 
valid SO2 emissions data in calculating %Ps and 
Eho under paragraphs (d), (e), or (f) of this section, as 
applicable, whether or not the minimum emissions data requirements under 
Sec. 60.46c(f) are achieved. All valid emissions data, including valid 
data collected during periods of startup, shutdown, and malfunction, 
shall be used in calculating %Ps or Eho pursuant 
to paragraphs (d), (e), or (f) of this section, as applicable.
