Section NR 670.022 - Specific feasibility and plan of operation report information requirements for boilers and industrial furnaces burning hazardous waste When an owner or operator of a cement kiln, lightweight aggregate kiln, solid fuel boiler, liquid fuel boiler or hydrochloric acid production furnace becomes subject to hazardous waste licensing requirements after October 12, 2005, or when an owner or operator of an existing cement, lightweight aggregate kiln, solid fuel boiler, liquid fuel boiler or hydrochloric acid production furnace demonstrates compliance with the air emission standards and limitations in 40 CFR part 63, subpart EEE (for instance, by conducting a comprehensive performance test and submitting a notification of compliance under 40 CFR 63.1207(j) and 63.1210(d) documenting compliance with 40 CFR part 63, subpart EEE), the requirements of this section do not apply. The requirements of this section do apply, however, if the department determines certain provisions are necessary to ensure compliance with ss. NR 666.102(5) (a) and (b) 3. if the owner or operator elects to comply with s. NR 670.235(1) (a) 1. to minimize emissions of toxic compounds from startup, shutdown and malfunction events; or if the facility is an area source and the owner or operator elects to comply with the ss. NR 666.105, 666.106, and 666.107 standards and associated requirements for particulate matter, hydrogen chloride and chlorine gas and non-mercury metals; or the department determines certain provisions apply, on a case-by-case basis, for purposes of information collection according to ss. NR 670.010(11) and (12) and 670.032(2) (b) and (c).
