 (a)  A person may not cause or permit the emission into the outdoor atmosphere of total reduced sulfur from kraft pulp mills in excess of the quantities in the following table:

   

	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—corrected to 8% oxygen by volume.
Recovery furnace—new design (with both welded wall or membrane wall construction or emission-control designed air systems)	5	12 hour average—corrected to 8% oxygen by volume.
Lime kiln (a rotary or fluosolid unit used to calcine calcium carbonate into calcium oxide)	20	Never to be exceeded— corrected to 10% oxygen by volume.
Digester systems (continuous or batch process for cooking wood chips in sodium hydroxide and sodium sulfide to produce cellulosic material)	5	Never to be exceeded.
Multiple effect evaporator system (vapor heads, heating elements, hot wells, condensers and associated equipment used to concentrate spent pulp mill cooking liquid)	5	Never to be exceeded.
Smelt dissolving tank (the vessel used to produce an aqueous solution from the molten mixture discharged from the floor of a recovery furnace)	20	Never to be exceeded.

 (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:

	MONTHS AFTER MAY 7, 1988
ACTIVITY	EXISTING SOURCES	RECOVERY
