### Project Description: I 

### A 1500 gallbn tank will be constructed outside of building 

### 2013. This tank vill**~ccept** 

### floor drains, 

### wash downs and any alcohol spill fro:D the dip 

### cleaning tanks. The tank 

### will be 

### provided W1th a**6~** single phase, 

### 208 volt

### heat the solution sufficient 

### to drive off alcohol vapors.! The tank will have a 

### cover with 

### four 4-inch vents to discharge 

### alcohtl vapors to the**at~osphere.** I 

### 2. Pollutant EJissions:

I 

### The primary!source of air**po11ut~ f~om**  

### the evaporation tank 

### will be isopropyl alcohdl vapors. 

### It is**es~imated** 

### that one day**opera~ion** 

### will yield**approxima~ely** 

### one quart of 

### alcohol per day per 

### tank and 

### the spray/cleaning qperations will yield about tvo 

### quarts of alcohol per 

### day. Thus, a**m~imum** 

### of one gallon alcohol per day vill**~e** 

### lost to the waste tank. :
