Section III-1503 - Emission Limitations and Compliance

A. Sulfuric Acid Plants-New and Existing. The emissions of sulfur dioxide and acid mist from new sulfuric acid production units that commence construction or modification after August 17, 1971, shall be limited to that specified in 40CFR 60.82 and 60.83, as incorporated by reference in LAC33:III.Chapter 30, i.e., 4.0 pounds of SO₂/ton of 100 percent H₂SO₄ (2 kilograms/metric ton) and 0.15 pounds of sulfuric acid mist/ton of 100percent H₂SO₄ (.075 kilograms/metric ton), respectively (three-hour averages). Emissions from existing units shall be limited as follows:

1. SO2- not more than 2000 ppm by volume (three-hour average);

2. sulfuric acid mist- not more than 0.5pounds/ton of 100 percent H₂SO₄ (0.25 kilograms/metric ton) (three-hour average).

B. Sulfur Recovery Plants-New and Existing. The emission of sulfur oxides calculated as sulfur dioxide from a new sulfur recovery plant that commences construction or modification after October 4, 1976, shall be limited to that specified in 40 CFR 60.104(a)(2), as incorporated by reference in LAC 33:III.Chapter 30. The emission of sulfur oxides calculated as sulfur dioxide from an existing plant shall be limited to a sulfur dioxide concentration of not more than 1,300 ppm by volume (three-hour average).

C. All Other Sources-New and Existing. No person shall discharge gases from the subject sources that contain concentrations of SO₂ in excess of 2,000 parts per million (ppm) by volume at standard conditions (three-hour average), or any applicable Federal NSPS or NESHAP emission limitation, whichever is more stringent. Single point sources that emit or have the potential to emit less than 250 tons per year of sulfur compounds measured as sulfur dioxide may be exempted from the 2,000 ppm(v) limitation by the administrative authority.

D. Compliance

1. The methods listed in Table 4 or any such equivalent method as may be approved by the administrative authority* shall be used to determine compliance with the appropriate emission limitations set forth in Subsections A-C of this Section. These methods shall be used for the following:

a. initial compliance determinations; and

b. any additional compliance determinations as requested by the administrative authority.

2. Measurement equipment shall be periodically calibrated to comply with minimal American Bureau of Standards criteria.

3. The data collected from a sulfur dioxide continuous emission monitoring system (CEMS) may be used to determine initial compliance with the sulfur dioxide emission limitations of this Section.

4. As used in this Section a three-hour average means the average emissions for any three consecutive one-hour periods (each commencing on the hour), provided that the number of three-hour periods during which the SO₂ limitation is exceeded is not greater than the number of one-hour periods during which the SO₂ limitation is exceeded.
