From the dryer during aeration. Fresh air is introduced into the dryer to evaporate residual perc remaining in the cloth. The perc-containing air is then vented through a control device or directly to the outside air.

NOTE: AQMD Rule 1421 prohibits the operation of any vented machine within AQMD jurisdiction as of 10/1/98.

Transfer Machine

• From the washer vent in the washer unit.

• From the manual transfer of clothing from a washer to a dryer.

Fugitive emissions:

• From fans when the machine door, button and lint traps are opened,

• From leaks around pumps, valves, flanges, seals, gaskets, and hose couplings.

• As a result of spotting and pressing operations, water-proofing treatments, waste distillation, evaporation losses from spent filters, and evaporation of residual perc remaining in clothing.
