(16)

Sources shall use the following procedures for converting monitoring data to units of the standard if necessary:

(a)

For indirect heat exchangers, the following procedures shall be used to convert gaseous emission monitoring data in parts per million to g/million cal (lb/million BTU):

1.

If the source elects to measure oxygen in the flue gases for an indirect heat exchanger pursuant to subsection (5)(a)2 of this section, the measurements of the pollutant concentration and oxygen concentration shall be on a dry basis and the following equation shall be used for the conversion procedure: E = CF(20.9) / (20.9-%O2);

2.

If the source elects to measure carbon dioxide in the flue gases pursuant to subsection (5)(a)2 of this section, the measurement of the pollutant concentration and the carbon dioxide concentration shall be on a consistent wet or dry basis and the following equation shall be used for the conversion procedure: E = CFc(100) / %CO2; and

3.

For subparagraphs 1 and 2 of this paragraph:

a.

E = pollutant emission, g/million cal (lb/million BTU);

b.

C = pollutant concentration, g/dscm (lb/dscf), determined by multiplying the average concentration (ppm) for each hourly period by 4.16 X 10-5 M g/dscm per ppm (2.64 X 10-9 M lb/dscf per ppm) where M = pollutant molecular weight, g/g-mole (lb/lb-mole). M = 64 for sulfur dioxide and 46 for oxides of nitrogen;

c.

%O2, %CO2 = oxygen or carbon dioxide volume (expressed as percent) determined with equipment specified in subsection (6) of this section; and

d.

F, Fc = a factor representing a ratio of the volume of dry flue gases generated to the calorific value of the fuel combusted (F), and a factor representing a ratio of the volume of the carbon dioxide generated to the calorific value of the fuel combusted (Fc) respectively. Values of F and Fc are given in 401 KAR 59:015 as applicable.

(b)

For sulfuric acid plants the owner or operator shall:

1.

Establish a conversion factor three (3) times daily pursuant to 40 C.F.R. 60.84;

2.

Multiply the conversion factor by the average sulfur dioxide concentration in the flue gases to obtain average sulfur dioxide emissions in kg/metric ton (lb/short ton); and

3.

Report the average sulfur dioxide emission for each averaging period in excess of the applicable emission standard in the quarterly report required in subsection (15) of this section.

(c)

The source may use data reporting or reduction procedures that vary from the provisions of this section if the source demonstrates that the alternate procedures are at least as accurate and protective as the requirements of this section and the alternative procedures may include:

1.

Alternative procedures for computing emission averages that do not require integration of data; and

2.

Alternative methods of converting pollutant concentration measurements to the units of the emission standards.

(17)

Sources may apply for approval of an alternative or equivalent method specified in 40 C.F.R. Part 60 or a test method specified in the Kentucky State Implementation Plan, if the alternative provisions are included in the source's permit and the source demonstrates:

(a)

The inability of CEMS to provide accurate determinations of emissions at the emissions unit;

(b)

The infrequent operation of the emissions unit;

(c)

The requirements of this section impose an extreme economic burden on the source; or

(d)

The CEMS is unable to be installed due to physical limitations at the source.
