Table 1 to Subpart HHHH of Part 63—Minimum Requirements for Monitoring and Recordkeeping
As stated in § 63.2998(c), you must comply with the minimum requirements for monitoring and recordkeeping in the following table:
You must monitor these parameters: | At this frequency: | And record for the monitored parameter: |
---|---|---|
1. Thermal oxidizer temperature 14 | Continuously | 15-minute and 3-hour block averages. |
2. Other process or control device parameters specified in your OMM plan 24 | As specified in your OMM plan | As specified in your OMM plan. |
3. Urea-formaldehyde resin solids application rate 4 | On each operating day, calculate the average lb/h application rate for each product manufactured during that day | The average lb/h value for each product manufactured during the day. |
4. Resin free-formaldehyde content 4 | For each lot of resin purchased | The value for each lot used during the operating day. |
5. Loss-on-ignition 34 | Measured at least once per day, for each product manufactured during that day | The value for each product manufactured during the operating day. |
6. UF-to-latex ratio in the binder 34 | For each batch of binder prepared the operating day | The value for each batch of binder prepared during the operating day. |
7. Weight of the final mat product per square (lb/roofing square) 34 | Each product manufactured during the operating day | The value for each product manufactured during the operating day. |
8. Average nonwoven wet-formed fiberglass mat production rate (roofing square/h) 34 | For each product manufactured during the operating day | The average value for each product manufactured during operating day. |
1 Required if a thermal oxidizer is used to control formaldehyde emissions.
2 Required if process modifications or a control device other than a thermal oxidizer is used to control formaldehyde emissions.
3 These parameters must be monitored and values recorded, but no operating limits apply.
4 You are not required to monitor or record these parameters during periods when using a non-HAP binder. If you do not monitor these parameters during periods when using a non-HAP binder, you must record the dates and times that production of mat using the non-HAP binder began and ended.
