Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
Ampere-Hours.
Each Chrome Plating Tank, or group of Chrome
				  Plating Tanks, shall have installed a continuous recording, non-resettable,
				  Ampere-Hour meter that operates on the electrical power lines connected to the
				  Tank or group of Tanks. A separate meter shall be hard-wired for each
				  rectifier.
(b)
Pressure
				  drop.
The Owner or Operator shall continuously monitor the pressure
				  drop across an Add-on Air Pollution Control Device such as a Composite Mesh-Pad
				  (CMP), Packed-Bed Scrubber (PBS, a CMP/PBS, Fiber-Bed Mist Eliminator, and a
				  HEPA Filter with a mechanical gauge. The gauge shall be located so that it can
				  be easily visible and in clear sight of the operation, or maintenance
				  personnel. The pressure drop shall be maintained within plus or minus 2 inches
				  of water of the value established during the Source Test to demonstrate
				  compliance with the Emission Limitation for CMP, PBS, a CMP/PBS, and a
				  Fiber-Bed Mist Eliminator. The pressure drop shall be maintained within -
				  ½ times to +2 times the inches of water of the value established during
				  the Source Test to demonstrate compliance with the Emission Limitation for HEPA
				  Filters.
(c)
Inlet velocity
				  pressure.
The Owner or Operator shall continuously monitor the inlet
				  velocity pressure of a Packed-Bed Scrubber with a mechanical gauge. The gauge
				  shall be located so that it can be easily visible and in clear sight of the
				  operation, or maintenance personnel. The inlet velocity pressure shall be
				  maintained within plus or minus 10 percent of the value established during the
				  Source Test to demonstrate compliance with the Emission Limitation.
(d)
Surface Tension.
(1) The Owner or Operator of a Facility that
				  is required to use a Chemical Fume Suppressant as specified in section
				  93102.8 to comply with section
				  93102.4 shall measure and monitor
				  the Surface Tension of the Chrome Plating Bath(s) that contains a Chemical Fume
				  Suppressant listed in Table 93102.8 of section
				  93102.8 with either a
				  Stalagmometer using the procedure in Appendix 7 of section
				  93102.16 or a procedure approved
				  by the District, or with a Tensiometer using U.S. EPA Method 306B (40 Code of
				  Federal Regulations, part 63, Appendix A). The Surface Tension shall be
				  maintained below the value required by section
				  93102.8. Surface Tension shall be
				  measured Daily for 20 Operating Days, and Weekly thereafter as long as there is
				  no violation of the Surface Tension requirement. If a violation occurs, the
				  measurement frequency shall return to Daily for 20 Operating Days, and Weekly
				  thereafter.
(2) The Owner or
				  Operator of a Facility using a Chemical Fume Suppressant containing a Wetting
				  Agent that is not required to use a Chemical Fume Suppressant listed in Table
				  93102.8 of section
				  93102.8 shall measure and monitor
				  the Surface Tension of the Chrome Plating Bath(s) with either a Stalagmometer
				  using the procedure in Appendix 7 of section
				  93102.16 or a procedure approved
				  by the District, or with a Tensiometer using U.S. EPA Method 306B (40 Code of
				  Federal Regulations, part 63, Appendix A). If the Surface Tension is measured
				  with a Stalagmometer, the Surface Tension shall be maintained below 45
				  dynes/centimeter. If the Surface Tension is measured with a Tensiometer, the
				  Surface Tension shall be maintained below 35 dynes/centimeter. Surface Tension
				  shall be measured Daily for 20 Operating Days, and Weekly thereafter as long as
				  there is no violation of the Surface Tension requirement. If a violation
				  occurs, the measurement frequency shall return to Daily for 20 Operating Days,
				  and Weekly thereafter.
(3)
				  Facilities with an approved alternative method of compliance as specified in
				  section 93102.14 and using Chemical Fume
				  Suppressants as all or partial control of Hexavalent Chromium emissions must
				  measure and monitor the Surface Tension of the Chrome Plating Bath Daily. The
				  Surface Tension must be maintained at or below the Surface Tension measured
				  during the Source Test.
