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

(c) You must not operate your municipal waste combustor so that the temperature measured at the inlet of the particulate matter control device exceeds 17 °C above the maximum demonstrated temperature of the particulate matter control device (4-hour block average), as specified under “Definitions” (§ 60.6145) except as specified in paragraphs (c)(1) and (2) of this section. The averaging time is specified under § 60.6000. The requirements specified in this paragraph apply to each particulate matter control device used.

(1) During the annual dioxins/furans or mercury performance test and the 2 weeks preceding the annual dioxins/furans or mercury performance test, the particulate matter control device temperature limitations are not applicable if the provisions of paragraph (c)(2) of this section are met.

(2) The Administrator may waive in writing the particulate matter control device temperature limits for the purpose of evaluating system performance, testing new technology or control technologies, diagnostic testing, or related activities for the purpose of improving facility performance or advancing the state-of-the-art for controlling facility emissions. The temperature limits continue to apply, and remain enforceable, until and unless the Administrator grants the waiver.
