TABLE 5-2
Control Methods
I. Applicable to all emissions
A. Decrease or eliminate production of emission
1. Change specification of product
2. Change design of product
3. Change process temperature, pressure, or cycle
4. Change specification of materials
5. Change the product
B. Confine the emissions
1. Enclose the source of emissions
2. Capture the emissions in an industrial exhaust system
3. Prevent drafts
C. Separate the contaminant from effluent gas stream
1. Scrub with liquid
II. Applicable specifically to particulate matter emissions
A, Decrease or eliminate particulate matter production
1. Change to process that does not require blasting, blending, buffing,
calcining, chipping, crushing, drilling, drying, grinding, milling,
polishing, pulverizing, sanding, sawing, spraying, tumbling, etc.
2. Change from solid to liquid or gaseous material
3. Change from dry to wet solid material
4. Change particle size of solid material
5. Change to process that does not require particulate material
B, Separate the contaminant from effluent gas stream
1. Gravity separator
2. Centrifugal separator
3. Filter
4. Electrostatic precipitator
III. Applicable specifically to gaseous emissions
A. Decrease or eliminate gas or vapor production
1. Change to process that does not require annealing, baking, boiling,
burning, casting, coating, cooking, dehydrating, dipping, distilling,
expelling, galvanizing, melting, pickling, plating, quenching,
reducing, rendering, roasting, smelting, etc.
2. Change from liquid or gaseous to solid material
3. Change to process that does not require gaseous or liquid material
B. Burn the contaminant to CO 2 and H 2O
1. Incinerator
2. Catalytic burner
C. Adsorb the contaminant
1. Activated carbon

structures, animals, the atmosphere, and human health. These costs are
called Damage Functions. To the extent that there is knowledge of Cost
Functions and Damage Functions, the Cost Effectiveness of control methods
and strategies can be determined by their interrelationship. Cost Effective-
ness is an estimate of how many dollars worth of damage can be averted
