Universal Citation: WI Admin Code ยง NR 408.05
Current through August 26, 2024
(1) By the time the proposed major source or major modification is to commence operation, sufficient offsetting emissions shall be in effect such that the total emissions from existing sources in the area, from new or modified sources which are not major sources and from the proposed source will be sufficiently less than total emissions from existing sources prior to the application for the permit to construct or modify so as to represent, when considered together with the plan provisions required under section 172 of the Act (42 USC 7502), reasonable further progress.
(2) For the purposes of satisfying the requirements of sub. (1):
(a)
The determination of total emissions at both the time prior to the application
for a permit subject to the requirements of this chapter and the time the
permitted source or modification would commence operation, shall be made in a
manner consistent with the assumptions in the applicable state implementation
plan approved by the administrator concerning baseline emissions for the
demonstration of reasonable further progress and attainment of the national
ambient air quality standards for the particular pollutant subject to review
under this chapter.
(b) To
demonstrate reasonable further progress a new or modified source subject to
review under this chapter shall obtain offsets in an amount equal to or greater
than the amount specified by the applicable offset ratio. If an offset ratio is
not specified, the offset ratio shall be at least 1 to 1.
