Louisiana Administrative Code, Title 33 ENVIRONMENTAL QUALITY, Part III Air (LAC 33:III)

Chapter 15. Emission Standards for Sulfur Dioxide

Section 1511. Continuous Emissions Monitoring
As adopted in the Louisiana Register April 20, 1992 (LR 18:0375) (AQ057)
Approved by EPA July 15, 1993 (58 FR 38060) effective September 13, 1993 (LAc59)

   A.  The owner or operator of any facility subject to the provisions of this Chapter shall install, calibrate, maintain and operate a measurement system or systems, installed in accordance with the manufacturers instructions, for continuously monitoring sulfur dioxide concentrations in the effluent of each process subject to this Chapter consistent with LAC 33:III.915.  The administrative authority shall not require continuous monitoring for flares and sources emitting less than 100 tons per year of sulfur dioxide into the atmosphere or as identified in 40 CFR, Part 51, Appendix "P".  "Continuous monitoring" is defined as sampling and recording of at least one measurement of sulfur dioxide concentration in each 15-minute period from the effluent of each affected process or the emission control system serving each affected process.

   B.  These measurement systems shall be certified according to the performance specifications in LAC 33:III.6105 (Performance Specification 2) and quality assured by the procedures in 40 CFR 60, Appendix "F".

   C.  As an alternative to continuous monitoring of sulfur dioxide emissions the administrative authority* may approve demonstration of compliance by monitoring the fuel hydrogen sulfide content and calculation of sulfur dioxide emissions for sources which burn fuel gas or refinery gas in multiple combustion units or by monitoring input sulfur and calculation of sulfur dioxide emissions for sources which burn or decompose sulfur-containing fuel and/or feedstock.
