Section 391-3-1-.02(2)(e), Particulate Emissions from Manufacturing Processes, is hereby approved only to the extent that it provides for the establishment, as permit conditions, of emission limits more stringent than those otherwise applicable under the currently approved Georgia regulations. Any application of this regulation which would result in permit provisions less stringent than those otherwise required by the State's regulations must be formally submitted to EPA for prior approval as a plan revision pursuant to section 110(a) of the Clean Air Act.
