March 11, 1981 Summary of PSD Policy Determinations Made by Region IV 3.16
|Summary of PSD policy determinations
during the period from November 13, 1980
to January 12, 1981:
Notebook Entries: 10.22; 12.9; 13.5; 2.15; 4.16; 5.9
- Treatment of fugitive emissions with
regard to PSD applicability.
- A proposed physical change must, by
itself, result in a net increase greater
than de minimus in order to be subject
to PSD (see PSD/120).
- Allowable emissions can be presumed to
represent actual emissions for new
sources and, therefore, an increase in
production at the PSD source is not an
increase in actual emissions. (Also see
- Example 3 above occurs at an existing
source which did not have a new source
construction permit under the SIP (see
- An iron foundry is considered to be one
of the 28 PSD categories (i.e., a
secondary metal production plant) if it
uses scrap metal to produce iron, even
if the metal is poured into molds.
- Applicability of offset requirements
from new source with a SIP construction
permit whose permit conditions did not
prohibit subsequent increases.
- A whiskey distillery is not considered
to be one of the 28 PSD categories,
specifically a chemical process plant.
A chemical process plant is any
establishment in Major Group 28 of the
SIC Code. Beverage distilleries are in
Major Group 20.
- A proposed increase in emissions is not
subject to PSD unless the triggering
increase is of the same pollutant as the
one for which a significant increase
results. (Also see PSD/120).
- The 50 ton per year exemption under 40
CFR 52.21(i)(7) is pollutant specific.
- Operating permits are not Federally
enforceable; however, the State can
impart Federally enforceable conditions
to a construction permit issued for the
source in accordance with the New Source
Review procedures of the SIP at the time
