- area classification
(1)
The commission shall, within one hundred eighty days after June 20, 1979, and thereafter from time to time, if evidence indicates a need, review the current classification of any attainment, nonattainment, or unclassifiable area within the state and shall revise the classification of any such area or part thereof which is calculated by air quality modeling or shown by monitored data or other reliable methods to be invalid.(2)
The commission shall, upon application by the owner or operator of any existing or proposed stationary source, review the designation of any attainment, nonattainment, or unclassifiable area within the state and shall revise the designation of any such area or part thereof which is calculated by air quality modeling or shown by monitored data or other reliable methods to be invalid.(2.5)
Whenever monitoring data for any pollutant for which an area is designated nonattainment demonstrate that the national ambient air quality standard for that pollutant has been attained in accordance with the criteria required under the federal act, the division and commission shall take expeditious action to redesignate the area as attainment for that pollutant.(3)
In making any determination regarding the attainment, nonattainment, or unclassifiable designation of any area within the state with regard to particulate matter, the commission shall consider and, if consistent with the requirements of Part D of the federal act, discount the effects of particulate matter not of a size or substance to adversely affect public health or welfare.(4)
All revisions of designations shall be submitted to the administrator of the United States environmental protection agency.
