(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.
