# §60.6000. How do I monitor the temperature of flue gases at the inlet of my particulate matter control device?

- (a) You must install, calibrate, maintain, and operate a device to continuously measure the temperature of the flue gas stream at the inlet of each particulate matter control device.
- (b) **Calculate the temperature of the flue gas stream in 4-hour block arithmetic averages.**
- (c) Determine the maximum demonstrated particulate matter control device temperature for each particulate matter control device during the initial performance test for dioxins/furans and each subsequent performance test specified in [§ 60.5970](/cfr/40/60.5970.md) during which you achieve compliance with the dioxins/furans emission limit. The maximum demonstrated particulate matter control device temperature is the highest 4-hour arithmetic average temperature achieved at the particulate matter control device inlet during four consecutive hours during the most recent test. If a subsequent dioxins/furans performance test is being performed on only one municipal waste combustor as specified in [§ 60.5980](/cfr/40/60.5980.md), you may apply the same maximum particulate matter control device temperature from the tested facility for all the similarly designed and operated municipal waste combustors.
