(a)Source Test requirements.(1) All Facilities that use Hexavalent Chromium for the purposes of Functional Chrome Plating must conduct an initial Source Test on all Tier III Tanks by January 1, 2026, to demonstrate compliance with the Hexavalent Chromium Emission Limitations in section 93102.4(c)(2) and section 93102.4(f)(2).(2) Functional Chrome Plating Facilities that undergo Modification(s) to Tier III Tanks that are not complete by January 1, 2026, must conduct an initial Source Test on these Tank(s) no later than 60 days after Initial Start-Up to demonstrate compliance with the applicable Hexavalent Chromium Emission Limitations in section 93102.4(e)(2)(B).(3) All Functional Chrome Plating Facilities that use Hexavalent Chromium must conduct a Source Test on all Tier III Tanks every 2 calendar years after the date of the previous Source Test.(4) The Source Test must be conducted using one of the approved test methods specified in section 93102.7(b). The Hexavalent Chromium emission rate shall be multiplied by the Facility Annual Permitted Ampere-Hour usage to determine the annual emissions of Hexavalent Chromium for the Facility.(5) Trivalent Chromium Plating facilities meeting the mg/dscm Emission Limitation specified in section 93102.6(a)(1)(A) must conduct a Source Test to demonstrate compliance with the total chromium Emission Limitation upon Initial Start-Up.(b)Approved test methods(1) A Source Test shall be conducted with a minimum of three test runs in accordance with one of the following test methods:(A) CARB Test Method 425, last amended July 28, 1997, (section 94135, Title 17, California Code of Regulations (CCR));(B) U.S. EPA Method 306, (40 Code of Federal Regulations, Part 63 Appendix A) with or without Hexavalent Chromium option (Method 306, section 2.2.3) provided that, if the total chromium option is used, the total chromium measurement must be assumed to be all Hexavalent Chromium; or(C) South Coast Air Quality Management District Method 205.1.(2) Smoke test to verify the seal integrity of covers designed to reduce chromium emissions from Chrome Plating Tanks (See Appendix 4).(3) When using a Tensiometer, Surface Tension shall be measured in accordance with U.S. EPA Method 306B (40 Code of Federal Regulations, Part 63 Appendix A). When using a Stalagmometer, Surface Tension shall be measured using the procedure set forth in Appendix 7, or an alternative procedure approved by the District.(c)Pre-Test protocol. Facilities subject to the provisions of section 93102.7(a) must submit a pre-test protocol to the District at least 60 days prior to conducting a Source Test. The pre-test protocol shall include the Source Test criteria for the Facility and all assumptions, required data, and calculated targets for testing the source target chromium concentration, the preliminary chromium analytical data, and the planned sampling parameters, including test methods. In addition, the pre-test protocol shall include information on equipment, logistics, personnel, and other resources necessary for an efficient and coordinated test.Cal. Code Regs. Tit. 17, § 93102.7
