40 CFR Appendix 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.
