PPM (VOLUME) DRY	CONDITION
Recovery furnace-old design (without welded wall or membrane wall construction or emission-control designed air systems)	20	12 hour average-correctedto 8% oxygen by volume.
Recovery furnace-new design (with both welded wall ormembrane wall constructionor emission-control designedair systems)	5	12 hour average-correctedto 8% oxygen by volume.
Lime kiln (a rotary or fluosolidunit used to calcine calciumcarbonate into calcium oxide)	20	Never to be exceeded-corrected to 10% oxygen by volume.

(b) Total reduced sulfur emissions shall be monitored continuously at recovery furnaces, digester systems and multiple effect evaporator systems unless emissions are incinerated at 1,200°F for .5 seconds or incinerated to provide equivalent total reduced sulfur control.

(1) Monitors, installation, operation, maintenance and reporting shall be as prescribed in Chapter 139 (relating to sampling and testing).

(2) TRS monitoring systems installed under this section shall meet the minimum data availability requirements in Chapter 139 Subchapter C (relating to requirements for source monitoring for stationary sources).

(3) The Department may use the data from the monitoring systems or from an alternate monitoring system to determine compliance with subsection (a).

(4) Source owners and operators shall achieve compliance with these monitoring provisions by May 7, 1991.

(c) Compliance with subsection (a) shall be achieved in accordance with the following schedule:
