40 CFR 60.6435: What are the operating practice requirements for my municipal waste combustor?

(a) You must meet the carbon monoxide emission limits specified in Table 2 to Subpart WWWW no later than March 10, 2031.
(b) You must not operate your municipal waste combustor at loads greater than 110 percent of the maximum demonstrated load of the municipal waste combustor (4-hour block average), as specified under “Definitions” (§ 60.6685), except as specified in paragraphs (b)(1) and (2) of this section. The averaging time is specified under § 60.6550.
(1) During the annual dioxins/furans or mercury performance test and the 2 weeks preceding the annual dioxins/furans or mercury performance test, the municipal waste combustor load limit is not applicable if the provisions of paragraph (b)(2) of this section are met.
(2) The Administrator may waive in writing the municipal waste combustor load limit 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 municipal waste combustor load limit continues to apply, and remains enforceable, until and unless the Administrator grants the waiver.
(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” (§ 60.6685), except as specified in paragraphs (c)(1) and (2) of this section. The averaging time is specified under § 60.6555. 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.
(d) If your municipal waste combustor uses activated carbon to control dioxins/furans or mercury emissions, you must meet the requirements for activated carbon injection rate during dioxins/furans or mercury testing as specified in § 60.6560.
