# 52.928 Control strategy: Sulfur oxides.

The revised SO<sub>2</sub> emission limit for large coal-fired boilers in Bell, Clark, and Woodford Counties, submitted on June 29, 1979, is disapproved since it does not provide for attainment and maintenance of all SO<sub>2</sub> NAAQS. The limit approved by EPA on May 10, 1976 (41 FR 19105), remains the limit applicable to these sources.

[49 FR 11091, Mar. 23, 1984]
