(a) Greenhouse Gases (GHGs) are subject to Prevention
of Significant Deterioration (PSD) review under the conditions specified
in paragraphs (1) or (2) of this subsection. Projects with increases
in GHG emissions do not require a PSD applicability evaluation for
GHGs unless the project requires PSD review for a pollutant other
than GHGs.
(1) New source, major for non-GHGs. The stationary
source is a new major stationary source for a federally regulated
new source review (NSR) pollutant that is not GHGs, and will emit
or have the potential to emit 75,000 tons per year (tpy) or more carbon
dioxide equivalent (CO2 e); or
(2) Existing source, major for non-GHGs. The stationary
source is an existing major stationary source for a federally regulated
NSR pollutant that is not GHGs, and will have a significant net emissions
increase of a federally regulated NSR pollutant that is not GHGs,
and a net emissions increase greater than zero tpy GHGs on a mass
basis and 75,000 tpy or more CO2 e.
(b) New stationary sources with emissions of GHGs,
or existing stationary sources that undertake a physical change or
change in the method of operations that includes emissions of GHGs,
that do not meet any of the conditions in subsection (a) of this section
do not require authorization for emissions of GHGs under this subchapter,
Subchapter F of this chapter (relating to Standard Permits), Subchapter
G of this chapter (relating to Flexible Permits), or Chapter 106 of
this title (relating to Permits by Rule). Owners or operators of these
sources must keep records sufficient to demonstrate the amount of
emissions of GHGs from the source as a result of construction, a physical
change or a change in method of operation do not require authorization
under subsection (a) of this section. Records must be made available
at the request of personnel from the commission or any local air pollution
control agency having jurisdiction. Records must be maintained for
a minimum of five years from the date of the construction, physical
change, or change in method of operation.
