### facility is a new building intended to consolidate the repair and painting of aircraft parts, and operations carried on in several buildings into this one facility.**~1aterial** 

### consumptions are based on existing operations and should potentially decrease because of operating efficiency in new facility. Efficiency is based on equipment specification for equipment not yet purchased. A. Operation: t'1in;J Surface Repair #112 1. 

### Pr imer Bex>th

- Operation moved from Building #220 to north center of new building. vertical exhaust discharge located 54' above grade. CFM total discharge. Air cleaning device

- 95% efficient water spray and wet plate baffles. 'Ibtal paint consumption for the entire operation includes:

a. 5 kits (2 gallons per kit) per month of MIL-C-83286: FSCM 

# ­ 33461, Deft Chemical Coatings, polyurethane coating. b. 1 aersol can per month of one of the following: (1) FSC1 09859 Arneron Industrial Coating Division, lacquer, acrylic. (2) FSQ1 12904, Lenrnar Lacquers, Inc., lacquer. (3)**FS~i**

### Tank #4

- Water only

- no exhaust. Tank #5

- Hater only

- no exhaust. Tank #6
