Such notice shall be given to the department not less than 30 days in advance of the proposed relocation unless a different time duration is previously approved by the department.
NR 405.07(5)
(5) The requirements of
ss. NR 405.08 to

NR 405.07 Note
Note: No de minimis air quality level is provided for ozone. However, any source with a net increase of 100 tons per year or more of volatile organic compounds or nitrogen oxides subject to regulation under this chapter would be required to perform an ambient impact analysis, including the gathering of ambient air quality data.
NR 405.07(8)(b)
(b) The concentrations of the air contaminant in the area that the source or modification would affect are less than the concentrations listed in
par. (a).
NR 405.07 Note

1m. A new major stationary source for a regulated NSR contaminant other than GHG, which will emit or will have the potential to emit 75,000 tpy or more of GHG on a carbon dioxide equivalent basis.
NR 405.07(9)(a)2m.
2m. An existing major stationary source for a regulated NSR contaminant other than GHG, which will have an emissions increase of a regulated NSR contaminant other than GHG, and an emissions increase of 75,000 tpy or more of GHG on a carbon dioxide equivalent basis.
NR 405.07 Note
Note: The department intends to regulate GHG consistent with the
40 CFR 51.166 (June 3, 2010). In the event of litigation or congressional action which impacts the federal regulations, the department will commence rulemaking to remain consistent with the resulting federal regulations.
NR 405.07(9)(b)
(b) For purposes of this subsection, emissions of GHG on a carbon dioxide equivalent basis shall be determined by multiplying the mass amount of emissions, in tons per year, for each of the constituent gases in the pollutant GHG by the associated global warming potential for the gas in Table B, and then summing the products obtained.
