Effective Date: October 24, 2007(d)(e)Pre-Test protocol. Facilities subject to the provisions of section93102.7(a) must submit a pre-test protocol to the permitting agencyat least 60 days prior to conducting a performance test. The pretestprotocol shall include the performance test criteria of the enduser and all assumptions, required data, and calculated targets fortesting the source target chromium concentration, the preliminarychromium analytical data, and the planned sampling parameters.In addition, the pre-test protocol shall include information onequipment, logistics, personnel, and other resources necessary foran efficient and coordinated test.Test all emission points. Each emission point subject to therequirements of this regulation must be tested unless a waiver isgranted by U.S. EPA and approved by the permitting agency.NOTE: Authority cited: Sections 39600, 39601, 39650, 39658, 39659, 39666, and 41511,Health and Safety Code.

The surface tension value may bemeasured using either a stalagmometer or a tensiometer.Table 93102.8: Chemical Fume Suppressants Approved for Use atSpecified Surface TensionsChemical FumeSuppressant andManufacturerStalagmometerMeasuredSurface Tension(dynes/centimeter)TensiometerMeasured SurfaceTension(dynes/centimeter)Benchbrite CR 1800 ®Benchmark Products < 40 < 35Clepo Chrome ®MacDermid < 40 < 35Fumetrol 140 ®Atotech U.S.A. < 40 < 35HCA-6.2 ®Hunter Chemical LLC < 32 < 28HCA-4 ®Hunter Chemical LLC < 32 < 2826
Effective Date: October 24, 2007(b)Alternative chemical fume suppressants. Chemical fumesuppressants not listed in Table 93102.8 may be used uponapproval by the Executive Officer. The Executive Officer shallapprove the use of an alternative chemical fume suppressant if thefollowing criteria are met:(1) The chemical fume suppressant has been performance testedunder conditions that are representative of normal operationsin a hexavalent chromium electroplating or anodizing bath anddemonstrated to reduce the hexavalent chromium emissionsbelow 0.01 milligrams per ampere hour; and(2) In the performance testing, the hexavalent chromium emissionrate of 0.01 milligrams per ampere-hour was achieved underconditions in which the surface tension did not exceed45 dynes/cm, as measured by a stalagmometer or35 dynes/cm, as measured by a tensiometer.(c)A chemical fume suppressant that is listed in subsection 93102.8(a)or that has been approved under subsection 93102.8(b) may nolonger be used if the Executive Officer determines that the chemicalfume suppressant is no longer able to reduce the hexavalentchromium emission rate below 0.01 milligrams per ampere-hourunder conditions in which the surface tension does not exceed45 dynes/cm, as measured by a stalagmometer or 35 dynes/cm, asmeasured by a tensiometer.NOTE: Authority cited: Sections 39600, 39601, 39650, 39658, 39659, and 39666, Health andSafety Code.

Each electroplating or anodizing tank, or group ofelectroplating or anodizing tanks, shall have installed a continuousrecording, non resettable, ampere-hour meter that operates on theelectrical power lines connected to the tank or group of tanks. Aseparate meter shall be hard-wired for each rectifier.Pressure drop. The owner or operator shall continuously monitorthe pressure drop across an add-on control device such as acomposite mesh-pad (CMP), packed-bed scrubber (PBS), aCMP/PBS, fiber-bed mist eliminator, and a High EfficiencyParticulate Arrestor (HEPA) filter with a mechanical gauge. Thegauge shall be located so that it can be easily visible and in clearsight of the operation, or maintenance personnel. The pressuredrop shall be maintained within plus or minus 2 inches of water of27
