Table 1 to Subpart HHHH of Part 63 - Minimum Requirements for Monitoring and Recordkeeping

As stated in ยง 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.
