Emissions of combustion ash from ash conveying systems (including conveyor transfer points) at large HMIWI shall not be visible for more than five percent (5%) of an observation period (i.e., nine (9) minutes per 3hour period), as determined by 40 C.F.R. § 60, Appendix A-1, Method 22, incorporated in § 39.4(A) of this Part, except as provided in §§ 39.9(B)(2) and (3) of this Part;2.

The provisions specified in § 39.9(B)(1) of this Part do not apply during maintenance and repair of ash conveying systems. Maintenance and/or repair shall not occur on more than 10 (ten) operating days per calendar quarter unless the owner or operator obtains written approval from the Office of Air Resources establishing a date whereby all necessary maintenance and repairs of ash conveying systems shall be completed.C. The emission limits in §§ 39.9(A) and (B) of this Part do not apply during periods of startup or shutdown, provided that no hospital waste or medical/infectious waste is charged to the HMIWI during those periods. During periods of malfunction the operator shall operate within established parameters as much as possible, and shall continue monitoring all applicable operating parameters until all waste has been combusted or until the malfunction ceases, whichever comes first. In addition, the malfunction must be reported to the Office of Air Resources within twenty-four (24) hours. A written report must be submitted to the Office of Air Resources within seven (7) days, which includes the cause of the malfunction, any exceedance, and actions taken to prevent reoccurrence.D. Any violation of the emission limitations in §§ 39.9(A) and (B) of this Part must be reported to the Office of Air Resources within twenty-four (24) hours.
