Chapter 124 - TOTAL REDUCED SULFUR CONTROL FROM KRAFT PULP MILLS
Section 096-124-4 - Monitoring of Emissions and Operations

A.For any lime kiln or recovery furnace, a continuous emissions monitoring system to monitor and record the concentration of TRS emissions on a dry basis and the percent of oxygen by volume on a dry basis in the gases discharged into the atmosphere. These systems must be located downstream of the control device(s), and the spans of these continuous emissions monitoring system(s) must be set as follows:

B.For any incinerator, or boiler with a maximum designed heat input of less than 50 million BTUs per hour, a monitoring device which continuously measures and records the combustion temperature which ensures TRS incineration of the LVHC, HVLC and steam stripper collection systems. The monitoring device must be accurate within ± one (1)% of the temperature being measured and must achieve 95% uptime based on quarterly incineration time;

C.For any smelt dissolving tank, stack testing must be performed at least once every two calendar years to demonstrate compliance with the smelt dissolving tank TRS emission rate as specified in Section 3(J) of this Chapter;

D. All continuous emission monitoring systems installed and operated pursuant to this section to monitor the concentration of TRS emissions and the percent oxygen by volume shall meet the sampling and performance criteria of 40 CFR Section 60.13 and the Performance Specifications 5 and 3, respectively, of 40 CFR Part 60, Appendix B and Chapter 117 of the Department Regulations; and

E.The Department and EPA may, on a case by case basis, consider alternative compliance methods for monitoring TRS emissions, such as Predictive Emission Monitoring Systems (PEMS). An approved alternative method shall be specified in the source's air emission license.
