Sec. 12.

(a) The owner or operator of a secondary lead smelter shall use the following test methods to determine compliance with the emission standards for lead compounds:

(1) 40 CFR 60, Appendix A-1, Method 1* to select the sampling port location and the number of traverse points.

(2) 40 CFR 60, Appendix A-1, Method 2* or 40 CFR 60, Appendix A-3, Method 5D, Section 8.3* for positive pressure fabric filters, to measure volumetric flow rate.

(3) 40 CFR 60, Appendix A-2, Method 3*, 40 CFR 60, Appendix A-2, Method 3A*, or 40 CFR 60, Appendix A-2, Method 3B* to determine the dry molecular weight of the stack gas.

(4) 40 CFR 60, Appendix A-3, Method 4* to determine moisture content of the stack gas.

(5) 40 CFR 60, Appendix A-8, Method 12* or 40 CFR 60, Appendix A-8, Method 29* to determine compliance with the lead compound emission standards. The minimum sample volume must be two (2.0) dry standard cubic meters (seventy (70) dry standard cubic feet) for each run. The owner or operator of a secondary lead smelter shall perform three (3) test runs and determine compliance using the average of the three (3) runs.

(b) The owner or operator of a secondary lead smelter shall use the following test methods to determine compliance with the emission standards for total hydrocarbons:

(1) 40 CFR 60, Appendix A-1, Method 1* to select the sampling port location and number of traverse points.

(2) The Single Point Integrated Sampling and Analytical Procedure in 40 CFR 60, Appendix A, Method 3B* to measure the carbon dioxide content of the stack gases when using either 40 CFR 60, Appendix A-2, Method 3A* or 40 CFR 60, Appendix A-2, Method 3B*.

(3) 40 CFR 60, Appendix A-3, Method 4* to measure moisture content of the stack gases.

(4) 40 CFR 60, Appendix A-7, Method 25A* to measure total hydrocarbon emissions. The minimum sampling time must be one (1) hour for each run. The owner or operator of a secondary lead smelter shall perform a minimum of three (3) test runs. The owner or operator of a secondary lead smelter shall calculate a one (1) hour average total hydrocarbons concentration for each run and use the average of the three (3) one (1) hour averages to determine compliance.

(c) The owner or operator of a secondary lead smelter shall correct the measured total hydrocarbon concentrations to four percent (4%) carbon dioxide, specified as follows:

(1) If the measured percent carbon dioxide is greater than four-tenths of one percent (0.4%) in each compliance test, the owner or operator of a secondary lead smelter shall determine the correction factor using the following equation:

Where:	F	=	Correction factor (no units).
	CO₂	=	Percent carbon dioxide measured using 40 CFR 60, Appendix A-2, Method 3A* or 40 CFR 60, Appendix A-2, Method 3B*, where the measured carbon dioxide is greater than four-tenths of one percent (0.4%).

(2) If the measured percent carbon dioxide is equal to or less than four-tenths of one percent (0.4%), the owner or operator of a secondary lead smelter shall use a correction factor (F) of ten (10).

(3) The owner or operator of a secondary lead smelter shall determine the corrected total hydrocarbons concentration by multiplying the measured total hydrocarbons concentration by the correction factor (F) determined for each compliance test.

(d) The owner or operator of a secondary lead smelter shall use the following test methods to determine compliance with the emission standards for dioxins and furans:

(1) 40 CFR 60, Appendix A-1, Method 1* to select the sampling port location and the number of traverse points.

(2) 40 CFR 60, Appendix A-1, Method 2* or 40 CFR 60, Appendix A-3, Method 5D, Section 8.3* for positive pressure fabric filters to measure volumetric flow rate.

(3) 40 CFR 60, Appendix A-2, Method 3A* or 40 CFR 60, Appendix A-2, Method 3B* to determine the oxygen and carbon dioxide concentrations of the stack gas.

(4) 40 CFR 60, Appendix A-3, Method 4* to determine moisture content of the stack gas.

(5) 40 CFR 60, Appendix A-7, Method 23* to determine the dioxins and furans concentration.

(e) The owner or operator of a secondary lead smelter shall determine the dioxins and furans toxic equivalency through the following procedures:

(1) Measure the concentration of each dioxins and furans congener shown in the following table using 40 CFR 60, Appendix A-7, Method 23*:


Dioxin/furan congener	Toxic equivalency factor (TEQ)
2,3,7,8-tetrachlorinated dibenzo-p-dioxin	1
1,2,3,7,8-pentachlorinated dibenzo-p-dioxin	0.5
1,2,3,4,7,8-hexachlorinated dibenzo-p-dioxin	0.1
1,2,3,7,8,9- hexachlorinated dibenzo-p-dioxin	0.1
1,2,3,6,7,8- hexachlorinated dibenzo-p-dioxin	0.1
1,2,3,4,6,7,8-heptachlorinated dibenzo-p-dioxin	0.01
Octachlorinated dibenzo-p-dioxin	0.001
2,3,7,8-tetrachlorinated dibenzofuran	0.1
2,3,4,7,8-pentachlorinated dibenzofuran	0.05
1,2,3,7,8-pentachlorinated dibenzofuran	0.5
1,2,3,4,7,8-hexachlorinated dibenzofuran	0.1
1,2,3,6,7,8-hexachlorinated dibenzofuran	0.1
1,2,3,7,8,9-hexachlorinated dibenzofuran	0.1

(2) Correct the concentration of dioxins and furans in terms of toxic equivalency to seven percent (7%) oxygen using the following equation:

Where:	C_adj	=	Dioxins and furans concentration adjusted to seven percent (7%) oxygen.
	C_meas	=	Dioxins and furans concentration measured in nanograms per dry standard cubic meter.
	(20.9-7)	=	Twenty and nine-tenths percent (20.9%) oxygen minus seven percent (7%) oxygen (defined oxygen correction basis).
	20.9	=	Percent of oxygen concentration in air.
	%O₂	=	Percent of oxygen concentration measured on a dry basis.

(3) For each dioxins and furans congener measured as specified in subdivisions (1) and (2), multiply the congener concentration by its corresponding toxic equivalency factor.

(4) Sum the values calculated as specified in subdivision (3) to obtain the total concentration of dioxins and furans emitted in terms of toxic equivalency.
