  • Air Quality Testing
    SCAQMD collected samples inside the following facilities to identify the specific equipment or processes within the facility that could be the sources of hexavalent chromium emissions that could explain the elevated levels seen at the ambient monitors.  Once the sources of emissions have been identified, SCAQMD can guide the facility to then reduce the emissions from those possible sources. Several possible sources were identified from the facilities that showed elevated levels of hexavalent chromium.  
  • Calculation Methodology for Evaluating Sampling Results for Curtailment Threshold for Orders for Abatement (PDF)  - March 2, 2017
    This calculation methodology describes the approach used to determine each facility’s contribution to a local monitor’s level of hexavalent chromium. Under the Stipulated Orders for Abatement for Anaplex and Aerocraft, curtailment of any chrome emitting operation is required if hexavalent chromium levels are more than 1.0 ng/m3 of hexavalent chromium to any monitor, averaged over three samples. This calculation methodology takes into account each facility’s contribution, typical levels of hexavalent chromium found regionally, and contributions from local sources. This approach may be modified in the future as more information becomes available.
