§ 52.623 Approval status.

(a) With the exceptions set forth in this subpart, the Administrator approves Hawaii's plan for attainment and maintenance of the national standards. The State included various provisions in its plan to provide for the attainment of the State ambient air quality standards. As described in the Governor's letters of January 28, May 8, and May 22, 1972, these provisions were included for information purposes only and were not to be considered a part of the plan to implement national standards. Accordingly, these additional provisions are not considered a part of the applicable plan.
