- Table 36 to Subpart UUU of Part 63—Work Practice Standards for HAP Emissions From Bypass Lines
As stated in § 63.1569(a)(1), you shall meet each work practice standard in the following table that applies to you.
| Option | You shall meet one of these equipment standards . . . | 1. Option 1 | Install and operate a device (including a flow indicator, level recorder, or electronic valve position monitor) to demonstrate, either continuously or at least every hour, whether flow is present in the by bypass line. Install the device at or as near as practical to the entrance to any bypass line that could divert the vent stream away from the control device to the atmosphere. | 2. Option 2 | Install a car-seal or lock-and-key device placed on the mechanism by which the bypass device flow position is controlled (e.g., valve handle, damper level) when the bypass device is in the closed position such that the bypass line valve cannot be opened without breaking the seal or removing the device. | 3. Option 3 | Seal the bypass line by installing a solid blind between piping flanges. | 4. Option 4 | Vent the bypass line to a control device that meets the appropriate requirements in this subpart. |
