[Code of Federal Regulations] [Title 40, Volume 12] [Revised as of July 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR63.1546] [Page 97-98] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 63_NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES--Table of Contents Subpart TTT_National Emission Standards for Hazardous Air Pollutants for 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: [[Page 98]] (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.
