# 52.2237 NO RACT and NO conformity exemption.

*Approval.* EPA is approving the section 182(f) oxides of nitrogen (NO<sub>X</sub>) reasonably available control technology (RACT) and NO<sub>X</sub> conformity exemption request submitted by the Tennessee Department of Environment and Conservation on March 21, 1995, for the five county middle Tennessee (Nashville) ozone moderate nonattainment area. This approval exempts the area from implementing federal NO<sub>X</sub> RACT on major sources of NO<sub>X</sub> and exempts Tennessee from NO<sub>X</sub> conformity. This approval does not exempt sources from any State required or State Implementation Plan (SIP) approved NO<sub>X</sub> controls. If a violation of the ozone NAAQS occurs in the area, the exemption from the requirement of section 182(f) of the CAA in the applicable area shall not apply.

[61 FR 54946, Oct. 23, 1996]
