Section III-1511 - Continuous Emissions Monitoring

A. Except as provided in Subsections C and D of this Section, the owner or operator of any facility subject to the sulfur dioxide emission limitations 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. Continuous monitoring is defined as sampling and recording of at least one measurement 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 Performance Specification 2 ( 40 CFR Part 60, Appendix B as incorporated by reference at LAC 33:III.3003) and quality assured by the procedures in 40 CFR Part 60, Appendix F.

C. As an alternative to continuous monitoring of sulfur dioxide emissions the administrative authority* may approve demonstration of compliance as follows.

1. For combustion units that burn fuel gas or refinery gas, calculate sulfur dioxide emissions by continuously monitoring the fuel hydrogen sulfide content and fuel consumption rate.

2. For any single point source that burns or decomposes sulfur-containing fuel and/or feedstock, calculate sulfur dioxide emissions by monitoring the fuel and/or feedstock consumption rate and determining input sulfur as follows.

a. For fuel supplied from a bulk storage tank, values for input sulfur shall be determined on each occasion that the fuel is transferred to the storage tank from any other source. Fuel consumption rates shall be monitored continuously.

b. For feedstock or any other method of supplying fuel, values for input sulfur shall be determined daily. Fuel consumption rates shall be monitored continuously.

3. As an alternative to Paragraphs C.1 and 2 of this Section, the owner or operator may develop custom schedules and methods for determination of sulfur dioxide emissions based on the design and operation of the emissions unit and characteristics of the feedstock or fuel supply. These custom schedules must be substantiated by data and approved by the administrative authority prior to implementation.

D. The administrative authority shall not require continuous monitoring for:

1. flares;

2. single point sources that have the potential to emit less than 100 tpy of sulfur dioxide;

3. single point sources identified in 40 CFR Part 51, Appendix P; and

4. single point sources subject to the provisions of 40 CFR Part 75 -Continuous Emission Monitoring.

E. For sulfuric acid plants, the production rate of H₂SO₄ shall be monitored daily.
