Table 5 to Subpart IIIII of Part 63—Required Elements of Floor-Level Mercury Vapor Measurement and Cell Room Monitoring Plans
Your Floor-Level Mercury Vapor Measurement Plan required by § 63.8192(d) and Cell Room Monitoring Plan required by § 63.8192(g) must contain the elements listed in the following table:
You must specify in your plan . . .
Floor-Level Mercury Vapor Measurement Plan
1. Locations in the cell room where you will measure the level of mercury vapor
The locations must be representative of the entire cell room floor area. At a minimum you must measure the level of mercury vapor above mercury-containing cell room equipment, as well as areas around the cells, decomposes, or other mercury-containing equipment.
2. Equipment or sampling and analytical methods that you will use to measure the level of mercury vapor
If an instrument or other equipment is used, the plan must include manufacturer specifications and calibration procedures. The plan must also include a description of how you will ensure that the instrument will be calibrated and maintained according to manufacturer specifications.
3. Measurement frequency
Measurements must take place at least once each half day.
4. Number of measurements
At least three readings must be taken at each sample location and the average of these readings must be recorded.
5. A floor-level mercury concentration action level
The action level may not be higher than 0.05 mg/m3.
Cell Room Monitoring Plan
1. Details of your mercury monitoring system.
2. How representative sampling will be conducted
Include some pre-plan measurements to demonstrate the profile of mercury concentration in the cell room and how the selected sampling locations ensure conducted representativeness.
3. Quality assurance/quality control procedures for your mercury monitoring system
Include a description of how you will keep records or other means to demonstrate that the system is operating properly.
4. Your action level
Include the background data used to establish your level.
