                          Primary Lead Smelting

 

Sec.  63.1546  Test methods.



    (a) The following procedure shall be used to determine compliance 

with the emissions standard for lead compounds under Sec.  63.1543(a):

    (1) The lead compound emission rate, in units of grams of lead per 

hour, for each source listed in Sec.  63.1543(a)(1) through Sec.  

63.1543(a)(9) shall be determined according to the following test 

methods in appendix A of part 60 of this chapter:

    (i) Method 1 shall be used to select the sampling port location and 

the number of traverse points.

    (ii) Method 2 shall be used to measure volumetric flow rate.

    (iii) Method 3 shall be used for gas analysis.

    (iv) Method 4 shall be used to determine moisture content of the 

stack gas

    (v) Method 12 shall be used to measure the lead emission rate of the 

stack gas. The minimum sample volume shall be 0.85 dry standard cubic 

meters (30 dry standard cubic feet) and the minimum sampling time shall 

be 60 minutes for each run. Three runs shall be performed and the 

average of the three runs shall be used to determine compliance.

    (2) The lead production rate, in units of megagrams per hour, shall 

be determined based on production data for the previous 12 calendar 

months according to the procedures detailed in paragraphs (a)(2)(i) 

through (a)(2)(v) of this section:

    (i) Total lead products production multiplied by the fractional lead 

content shall be determined in units of megragrams.

    (ii) Total copper matte production multiplied by the fractional lead 

content shall be determined in units of megragrams.

    (iii) Total copper speiss production multiplied by the fractional 

lead content shall be determined in units of megragrams.

    (iv) Total lead production shall be determined by summing the values 

obtained in paragraphs (a)(2)(i) through (a)(2)(iii) of this section.

    (v) The lead production rate, in units of megragrams per hours, 

shall be calculated based on the total lead production, as determined in 

accordance with paragraph (a)(2)(iv) of this section, divided by the 

total plant operating time, in hours, for the previous 12 months.

    (3) The sum of lead compound emission rates for the sources in Sec.  

63.1543(a)((1) through (a)(9), as determined in accordance with 

paragraph (a)(1) of this section, shall be divided by the lead 

production rate, as determined in accordance with paragraph (a)(2)(v) of 

this section, to obtain a production-based, lead compound emission rate 

in units of grams of lead per megagram of lead metal produced. The 

production-based, lead compound emission rate shall be used to determine 

compliance with the emissions standard for lead compounds under Sec.  

63.1543(a).

    (b) Owner and operators shall perform an initial compliance test to 

demonstrate compliance with the sinter building in-draft requirements of 

Sec.  63.1543(c) at each doorway opening in accordance with paragraphs 

(b)(1) through (b)(4) of this section.

    (1) Use a propeller anemometer or equivalent device.

    (2) Determine doorway in-draft by placing the anemometer in the 

plane of the doorway opening near its center.

    (3) Determine doorway in-draft for each doorway that is open during 

normal operation with all remaining doorways in their customary position 

during normal operation.

    (4) Do not determine doorway in-draft when ambient wind speed 

exceeds 2 meters per second.
