- Table 8 to Subpart IIIII of Part 63—Requirements for Cell Room Monitoring Program

As stated in § 63.8192(g)(1), your mercury monitoring system must meet the requirements contained in the following table:

If you utilize an . . . Your . . . Must . . . 1. Extractive cold vapor spectroscopy systema. Mercury vapor analyzerBe capable of continuously monitoring the elemental mercury concentration with a detection level at least two times lower than the baseline mercury concentration in the cell room. b. Sampling systemObtain measurements at three or more locations along the center aisle of the cell room at a height sufficient to ensure that sample is representative of the entire cell room. One sampling location must be above the midpoint of the center aisle, and the other two an equidistance between the midpoint and the end of the cells. 2. Open path differential optical absorption spectroscopy systema. Mercury vapor analyzerBe capable of continuously monitoring the elemental mercury concentration with a detection level at least two times lower than the baseline mercury concentration in the cell room. b. PathBe directed along the center aisle at a height sufficient to ensure that the sample is representative of the entire cell room.
