How do the section 182(f) NO X exemption provisions apply for the 8-hour NAAQS?

(a) A person may petition the Administrator for an exemption from NO X obligations under section 182(f) for any area designated nonattainment for the 8-hour ozone NAAQS and for any area in a section 184 ozone transport region. (b) The petition must contain adequate documentation that the criteria in section 182(f) are met. (c) A section 182(f) NO X exemption granted for the 1-hour ozone standard does not relieve the area from any NO X obligations under section 182(f) for the 8-hour ozone standard.
