Note 3: If a chromium value is in excess of the Target Air Quality Level (0.6 ug/m3), this will result in a stoppage of work; and, that sample will be speciated for chromium VI to determine that its concentration does not exceed the USEPA Site Specific Trigger Level for chromium VI, and the appropriate actions pertaining to an exceedance of the USEPA Site Specific Trigger Level will continue to be conducted.
