(b) The owner or operator of an affected facility, which is controlled by a solvent recovery device, shall maintain a calendar month record of the amount of solvent applied in the coating at each affected facility.

(c) The owner or operator of an affected facility, which is controlled by a solvent recovery device, shall install, calibrate, maintain, and operate a monitoring device for indicating the cumulative amount of solvent recovered by the device over a calendar month period. The monitoring device shall be accurate within +2.0 percent. The owner or operator shall maintain a calendar month record of the amount of solvent recovered by the device.

(d) The owner or operator of an affected facility operating at the conditions specified in Rule 260.440(b) shall maintain a 12-month record of the amount of solvent applied in the coating at the facility.
