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 perameter:|
|1. Thermal oxidizer temperature a||Continuously||15-minute and 3-hour block averages.|
|2. Other process or control device parameters specified in your OMM b plan.||As specified in your OMM plan||As specified in your OMM plan.|
|3. Urea-formaldehyde resin solids application rate.||On each operating day, calculate the average lb/hr application rate for each product manufactured during that day.||The average lb/hr value for each product manufactured during the day.|
|4. Resin free-formaldehyde content||For each lot of resin purchased||The value for each lot used during the operating day.|
|5. Loss-on-ignition c||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 c||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) c||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 squares per the hour) c||For each product manufactured during the operating day.||The average value for each product manufactured during operating day.|
a Required if a thermal oxidizer is used to control formaldehyde emissions.
b Required if process modifications or a control device other than a thermal oxidizer is used to control emissions.
c These parameters must be monitored and values recorded, but no operating limits apply.
