INSTRUCTIONS FOR
COMPLETION OF ADEM FORM 112
Item 1:
Self-explanatory.
Item 2:
Each degreasing unit should be identified here. This identification should
be used consistently throughout this form to describe the actual degreasing
unit. List all solvents utilized by each degreasing unit. Solvent consumption
should be based on the amount of solvents purchased minus the amount of
solvents reclaimed if any. Reclaimed solvents include only those solvents
which have been recovered for reuse or have been separated for disposal.
Estimates of disposed solvent amounts must be based on accurate and well
kept records. Use additional sheets if necessary.
Item 3:
The type of solvent metal cleaning operation is to be indicated here. This
form may be completed for more than one type of operation.
Item 4:
Self-explanatory.
Item 5:
The description of the solvent metal cleaning device(s)should be given here.
The vapor area should be equal to that area within the degreasing unit,
length x width, in which the solvent remains in a gaseous form.
The
freeboard ratio is equal to the freeboard height divided by the width of the
degreaser. For cold cleaning devices, the freeboard height is equal to the
distance from the solvent liquid level in the degreaser tank to the lip of the
tank. For vapor degreasers, the freeboard height is equal to the distance
from the solvent vapor level in the tank to the lip of the tank. The operating
time should include only that time in which the degreasing unit is being
operated in terms of hours per day, days per week and weeks per year.
Item 6:
Give a chronological history of the degreasing operation including the
original installation date, modification dates and a detailed description of
each modification made.
Include in this description, the effect the
modification(s) had on the capacity of the unit as well as any effects the
modification(s) had on the amount or type of air contaminants emitted from
the degreasing operation.
Include a separate history for each unit
identifying the unit with the appropriate degreaser identification.
Use
additional sheets if necessary.

Item 7
Self-explanatory
Item 8
Each stack, vent, etc. which may emit air contaminants is to be separately
identified with a number which is also used in Item 12. Stack height is that
Universal Transverse
above ground level. UTM Coordinates, which means
Mercator
Coordinates, for Alabama, N-S is between 3337.000km-
3875.000km and E-W is between 362.000km-709.000km; Zone 16. Standard
temperature is 70°F; standard pressure is 29.92 inches of Hg. Volume of gas
discharged can be calculated with the gas velocity (FPS) and stack diameter
(Ft).
Item 9:
Each stack, vent, etc., which may emit air contaminants, along with its
appropriate degreaser identification, is to be separately identified with a
number which was also used in Item 8. Pollutants should not be listed as
"VOC's" in Item 9 but should include the actual chemicals which make up the
solvent i.e. xylene, toluene, etc.. The basis of the estimates should include
material balance, stack test, emission factors manual, etc.. Emission points
not associated with a stack or vent should be labeled as "Fugitives".
Flow
If applications for more than one permit are being submitted for a facility, the
diagram
use of a single flow diagram for the entire facility is allowed. The use of one
flow diagram is suggested for integrated operations.
Points of air
contaminant emissions are to be numbered and degreaser identifications
are to be labeled to correspond with the numbers and labels listed in Items
8 and 9.
