Fla. Admin. Code Ann. R. 62-212.400 - Prevention of Significant Deterioration (PSD)
(1) General Provisions.
(a) No person shall construct any new major
stationary source or undertake any major modification except in compliance with
the provisions of this rule and, where applicable, Rule
62-212.500, F.A.C. Emissions of
an affected pollutant from a new major stationary source or major modification
which is located in or proposed to be located in any nonattainment area are not
subject to this rule.
(b) The
Department shall include conditions in each permit issued to insure that the
provisions of this rule are not violated.
(c) For purposes of this rule, the term
"Administrator, " wherever it appears in any provision of
40 CFR
52.21 cited herein, shall mean
"Department."
(2)
Applicability.
(a) The requirements of
subsections 62-212.400(4) through
(12), F.A.C., apply to the construction of
any new major stationary source or the major modification of any existing major
stationary source. The Department shall determine whether a major modification
will occur for each PSD pollutant as follows:
1. Baseline Actual-to-Projected Actual
Applicability Test for Modifications at Existing Emissions Units. A significant
emissions increase of a PSD pollutant will occur if the difference, or the sum
of the differences if more than one emissions unit is involved, between the
projected actual emissions and the baseline actual emissions equals or exceeds
the significant emissions rate for that pollutant. If a combination of new and
existing emissions units is involved, then the major modification shall be
determined by the hybrid test for multiple types of emissions units pursuant to
subparagraph 62-212.400(2)(a)
3., F.A.C.
2. Baseline
Actual-to-Potential Applicability Test for Construction of New Emissions Units.
A significant emissions increase of a PSD pollutant will occur if the
difference, or the sum of the differences if more than one emissions unit is
involved, between the potential to emit from each new emissions unit following
completion of the construction and the baseline actual emissions of these units
before the construction equals or exceeds the significant emissions rate for
that pollutant. If a combination of new and existing emissions units is
involved, then the major modification shall be determined by the hybrid test
for multiple types of emissions units pursuant to subparagraph
62-212.400(2)(a)
3., F.A.C.
3. Hybrid Test for
Multiple Types of Emissions Units. A significant emissions increase of a PSD
pollutant will occur if the sum of the emissions increases for all emissions
units, using the method specified above for each type of emissions unit equals
or exceeds the significant emissions rate for that
pollutant.
(b) Any owner
or operator of any existing major stationary source seeking to establish or
change a plantwide applicability limitation (PAL) for a PSD pollutant shall
comply with the requirements under Rule
62-212.720,
F.A.C.
(3) Exemptions.
