Sec. 63.7142  What are the requirements for claiming area source status?



    (a) If you wish to claim that your LMP is an area source, you must 

measure the emissions of hydrogen chloride from all lime kilns, except 

as provided in paragraph (c) of this section, at your plant using 

either:

    (1) EPA Method 320 of appendix A to this part,

    (2) EPA Method 321 of appendix A to this part, or

    (3) ASTM Method D6735-01, Standard Test Method for Measurement of 

Gaseous Chlorides and Fluorides from Mineral Calcining Exhaust Sources--

Impinger Method, provided that the provisions in paragraphs (a)(3)(i) 

through (vi) of this section are followed.

    (i) A test must include three or more runs in which a pair of 

samples is obtained simultaneously for each run according to section 

11.2.6 of ASTM Method D6735-01.

    (ii) You must calculate the test run standard deviation of each set 

of paired samples to quantify data precision, according to Equation 1 of 

this section:

Where:



RSDa = The test run relative standard deviation of sample 

pair a, percent.

C1a and C2a = The HCl concentrations, milligram/

dry standard cubic meter(mg/dscm), from the paired samples.



    (iii) You must calculate the test average relative standard 

deviation according to Equation 2 of this section:

[GRAPHIC] [TIFF OMITTED] TR05JA04.004



Where:



RSDTA = The test average relative standard deviation, 

percent.

RSDa = The test run relative standard deviation for sample 

pair a.

p = The number of test runs, =3.



    (iv) If RSDTA is greater than 20 percent, the data are 

invalid and the test must be repeated.

    (v) The post-test analyte spike procedure of section 11.2.7 of ASTM 

Method D6735-01 is conducted, and the percent recovery is calculated 

according to section 12.6 of ASTM Method D6735-01.

    (vi) If the percent recovery is between 70 percent and 130 percent, 

inclusive, the test is valid. If the percent recovery is outside of this 

range, the data are considered invalid, and the test must be repeated.

    (b) If you conduct tests to determine the rates of emission of 

specific organic HAP from lime kilns at LMP for use in applicability 

determinations under Sec. 63.7081, you may use either:

    (1) Method 320 of appendix A to this part, or

    (2) Method 18 of appendix A to part 60 of this chapter, or

    (3) ASTM D6420-99, Standard Test Method for Determination of Gaseous 

Organic Compounds by Direct Interface Gas Chromatography-Mass 

Spectrometry (GC/MS), provided that the provisions of paragraphs 

(b)(3)(i) through (iv) of this section are followed:



[[Page 50]]



    (i) The target compound(s) are those listed in section 1.1 of ASTM 

D6420-99;

    (ii) The target concentration is between 150 parts per billion by 

volume and 100 parts per million by volume;

    (iii) For target compound(s) not listed in Table 1.1 of ASTM D6420-

99, but potentially detected by mass spectrometry, the additional system 

continuing calibration check after each run, as detailed in section 

10.5.3 of ASTM D6420-99, is conducted, met, documented, and submitted 

with the data report, even if there is no moisture condenser used or the 

compound is not considered water soluble; and

    (iv) For target compound(s) not listed in Table 1.1 of ASTM D6420-

99, and not amenable to detection by mass spectrometry, ASTM D6420-99 

may not be used.

    (c) It is left to the discretion of the permitting authority whether 

or not idled kilns must be tested for (HCl) to claim area source status. 

If the facility has kilns that use common feed materials and fuel, are 

essentially identical in design, and use essentially identical emission 

controls, the permitting authority may also determine if one kiln can be 

tested, and the HCl emissions for the other essentially identical kilns 

be estimated from that test.
