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 temperature14Continuously15-minute and 3-hour block averages.
2. Other process or control device parameters specified in your OMM plan24As specified in your OMM planAs specified in your OMM plan.
3. Urea-formaldehyde resin solids application rate4On each operating day, calculate the average lb/h application rate for each product manufactured during that dayThe average lb/h value for each product manufactured during the day.
4. Resin free-formaldehyde content4For each lot of resin purchasedThe value for each lot used during the operating day.
5. Loss-on-ignition34Measured at least once per day, for each product manufactured during that dayThe value for each product manufactured during the operating day.
6. UF-to-latex ratio in the binder34For each batch of binder prepared the operating dayThe value for each batch of binder prepared during the operating day.
7. Weight of the final mat product per square (lb/roofing square)34Each product manufactured during the operating dayThe value for each product manufactured during the operating day.
8. Average nonwoven wet-formed fiberglass mat production rate (roofing square/h)34For each product manufactured during the operating dayThe average value for each product manufactured during operating day.

1Required if a thermal oxidizer is used to control formaldehyde emissions.

2Required if process modifications or a control device other than a thermal oxidizer is used to control formaldehyde emissions.

3These parameters must be monitored and values recorded, but no operating limits apply.

4You 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.
