Section 1200-03-12-.04 - MONITORING REQUIRED FOR DETERMINING COMPLIANCE OF CERTAIN LARGE SOURCES(1) For a fossil fuel-fired steam generator using solid fuel subject to subparagraph 1200-3-14-.02(1)(d), the source owner or operator may choose the method of measuring sulfur dioxide in the stack gases depending upon the type of fuel burned. No later than 30 days after the effective date of this regulation, the source owner or operator must inform the Technical Secretary be certified mail of the method to be utilized. If no choice is made by that date the owner or operator must monitor using the method outlined in subparagraph (2)(b) of this rule.(2) The available sulfur dioxide measurement methods are as follows:(a) If low sulfur coal is the only solid fuel burned, fuel analysis procedures and methods of calculations as prescribed by the Technical Secretary may be used. The purpose of this rule, low sulfur coal is defined as coal containing less than 1.00% sulfur be weight on a dry basis. Determination will be based on records of fuel burning during calendar year 1974. The procedures used to determine if the sulfur content of the fuel meet this 1.00% limitation during this time period will be subject to approval by the Technical Secretary. If the source owner or operator elects this method, the Technical Secretary will specify the data to be submitted to verify that the sulfur content is less than the 1.00% limitation. For facilities that elect to use fuel analysis procedures, fuels are not required to be sampled or analyzed for preparation of reports of compliance until the Technical Secretary specifies the procedures and requirements. If the 1.00% limit is ever exceeded then the method specified in subparagraph (b) of this paragraph must be used for monitoring.(b) Measurement of sulfur dioxide in the stack gases may be accomplished by the installation and operation of a continuous in-stack sulfur dioxide monitoring instrument. The type of monitor and its location will be subject to approval by the Technical Secretary. The in-stack monitoring instrument will be subject to the provisions of paragraph 1200-3-10-.02(1)(f) of these regulations.(3) For sulfuric acid plants and liquid sulfur dioxide plants located in a Class I county and existing on January 1, 1979, the measurement of sulfur dioxide in the stack gases must be accomplished by the installation and operation of a continuous in-stack sulfur dioxide monitor. The type of monitor and its location will be subject to approval by the Technical Secretary. The in-stack monitoring instrument will be subject to the provisions of paragraph 1200-3-10-.02(1) of these regulations.(4) For recovery furnaces and lime kilns located at kraft mills the measurement of total reduced sulfur compounds in stack gases must be accomplished by the installation and operation of a continuous in-stack total reduced sulfur (TRS) monitor. Such TRS monitor shall be accompanied by a continuous monitoring system for the measurement of the percent oxygen. The type of monitor and its location will be subject to approval by the Technical Secretary. The in-stack monitoring instrument will be subject to the provisions of paragraph 1200-3-10-.02(1) of these regulations.Tenn. Comp. R. & Regs. 1200-03-12-.04
