### . The information is provided in 

### the same· order as requested in Mr. 

### Ricker's· letter of··l March 1978.

1. 

### rume scrubber and mist eliminator in 

### ·the chemical cleaning area,**~lso** 

### quantity of cleaning fluids used:

a. The fume scrubber**~stem** 

### is a water wash, impingement ball type pack 12 inches thick with 1,200 square feet of surface area. Water is sprayed: through 

# a pressure nozzle**~stem** 

### across the entire face of the scrubber pack at a rate of 1 1/3 gallons per minut"e per square foot of pack. The tank

. ventilation discharge air is distributed across. the fac.e of the pack. The maximum 

### velocity through the scrubber system shall not exceed 400 FPM. 

### Downstream from the scrubber pack system will be 800 square feet ·of Z-frame moisture eliminators. This system 

### shall be certified ·to remove at least 99 percent of the soluble contaminates from the**v~tilation** 

### effluent air stream.
b. The total volume of paint st.ripping and cleaning agents used in 

### this process is 116,300 gallons.

. 2. Paint booths with scrubber, also quantity and type of paints and paint thinner:

a. All paint spray operations in 

### building 507 will 

### be accomplished in
seven water wash type paint booths. These booths will 

### be four DeVilbiss Model XXW-6848, size 8' X 9' X 10' working area with 14,000 CFM exhaust

. fans, and three Model XSW, size lb' X 12' X 14' worldng area and 27,175 

# crn fans. Attached is a copy of the manufacturer's specifications fc;>r these paint booths. The booth dimensions listed in the attachment do not correspond exactly w:i.th those given, because the booths were custom built for previous

## 3. 'IYPeof emissions from process ovens: There will be five process ovens

. installed in the landing gear overhaul facility.

a. Three each expansion ovens with thru.-belt conveyors to be llsed to thermally expand aircraft wheels so the bearing cups can be removed. These
ovens are electrically heated with a maximum 

### temperature of 

### 400 0 

### F. No product
or combustion emissions will- be generated.
b. One each paint.drying oven that is heated by infrared lamps to a 

### maxirrium temperature of 250 o F. Emissions will be 

### small quantitieo of**volatil~** 

### paint**thinn~rs,.** 

### which are included in the emissions estimated in 

### part .2c.

c. ·One each· steel bake oven to be used to release entrapped hydrogen in steel aircraft components that was introduced· during chemical cleaning. This
oven is heated by 

### natUral gas firing with an electrically heated backup system and' has a capacity of' 

### 6 million BTU per hour. The maximum 

### temperature will be 375 0 

### F and no product emissions will 

### be generated. The only emission to the

. atmosphere will be the combustion by-products of the natural gas firing system. The average heating rate' of this unit is estimated to. be 2 miJJion BTU per hour and the oven 

## w:i.li be used 16 hours per day, 5 days a week. Using the heating value of natural gas provided in 

## AP-42 (10 

## 50 BTUI cu ft), the furnace will 

### require 152,400 cubic feet per week or 7.924 million cubic feet per year. Using factors provided by Table 1.4-1 of AP-42 (commercial heating) the following emissions are estimated from this oven: Emissions Pollutant Factor

. Baghouse :in the mechanical cleaning area along with efficiencies, types and flow rates:

. There will be five bag house type dust collectors installed outside the building to support all 

### mechanical 

## (air blast) cleaning of aircraft parts. The parts air blasted are steel and aluminum. 

### The blast media will 

### be 80-180 grit alumaxide or agasite (walnut shell or cracked bard wheat). Three of these unitswill be 10,000 CFM cloth screen collectors with 

### 2,800 square feet of filtering fabric, one 6,.9J0 eFM unit and one 6,000, CFM unit. One 

### 10,000 

# cm unit is a Pangborn CH-3 type and· four are American Air Filter Corporation Fabric Pulse machines (size 12-168-2694). Both Units have' automatic·reverseair cleaning and 

### a..--re designed to comply with current. OSHA requirements. According to "Air Pollution :Engineering 

## Manual", pUblished by 

### the 'U. 

### S. ' Department of Health, Education and 

### Welfare (Public Health Service, Cincinnati, Ohio, 1967), baghouses are the most wide:q used type of collector for blasting operations and "the positive collection mechanism of .the baghouse ensures virtually 100 

### percent collection efficiency for an adequately ,sized unit in 

### good condition."

. 

## 5. Melt furnaces, type of firing and control:

a. There will 

### be four melt furnaces installed in the frnmd.ry area. Two of these furnaces are 1,000 pound capacity**.~:'il}:.** 

## tlPe units and will be used to pour lead and Kirksite (lead zinc copper alloy) drop hanuner dies, with a maximum 

### temperature of 1,OOOoF. Two 

### furnaces of' 

## 250 pound capacity will be used for aluminum and brass casting. The furnaces ·are used to melt virgin materials (no contaminants) and fit into the category of "crucibles or pots"
as defined by 

### AP-42.
b. There are no cleaning devices planned for the emissions from these furnaces. 'However, as indicated in our earlier submittal, the fumes from these furnaces are exhausted through a 30 foot stack which will 

### allow some particulates to drop out. Using emission factors from 

## AP-42 and assuming
no removal in the stack, the estimated particulate emissions from· the metal melting is: Yearly Melt &ti.ssion Factor Particulate Ernissic (Tons) (Lb/Tons) (Lbs/Year)
Lead 

## 0.8 15.6 Kirksite ]2.0* 

## 288.0 Aluminum 

## 1.9 

## 3.6 Brass 12.0* 

## 3.0
Total: 

## 310.2
*AP-42 gives no factors for Kitksite so the factor for brass was utilized (both are zinc copper alloys).

### c. The four melt furnaces are all 

### fired by 

### natural gas and forced air 

### draft. '11le two 1,000 ,pound capacity units have maximum ratings of 

## 2. 5**milli~** 

### BTU per hour to melt 3,000 pounds per hour. No rating could be found on the 

## ,250 pound capacity units, but it is assumed they are similar (i.e.

### BTU per hour to melt 7r;IJ 

### pounds per hour). Using these maximum

Powerful scrubbing i1ction with

.. 11ellJGc of wiltcr-r)S only a multiple-nozzle-type spray produces-removes' paint particles from the exhaust air. The design of the swirl-type nozzles and their spacing provide a thick, dense curtain of coarse drops that trap paint arid carry it into the tank for easy removal. Baffles between the washing area and the fan are so positioned as to throw out and catch any tree water before it reaches the stack. When the ilir reaches the exhaust system, it is free of paint and water particles. This simple principle of

. operation is highly efficient and easily maintained; it

. has been proved in thousands**o~** installations. Water wash booths with ei.ther the elevated or low level chambef" are availabln in a variety of capacities to efficiently remove the air·borne paint**p~rticles** result· ing from spraying operations. . ' Elevated chambers are- preferred whenever suffiCient building ceiling height is available. low type chambers
are employed where building ceiling heights restrict tne! use of the elevated type. Standard duty chambers provide sufficient washing capacity for applications involving a moderate amount of painting, such as maintenance painting, or moderate speed conveyorized jobs. Heavy duty chambers provide extra air washing capa­ bility for high production. applications**invqlv~ng** high painting rates. Two standard air velocities of 125 and 150 FoPM are offered to meet industry and code standards. Generally 125 FPM meets most requirements and 150 FPM is avail.

SUBJECT: Landing Gear Overhaul Facility

- Notice of Intent to Construet (Your 

### Ltr, 6 Mar 1978)

TO: DE
The questions asked by the attached Social Services letter of 1 March 1978
are as follows:

a. Fume scrubber and mist eliminator in the chemical cleaning area, also quantity of cleaning fluids used: (1) The fume scrubber system is a water wash, impingement ball type pack 12 inches thick with 1,200 square feet of surface area. Water is sprayed through a pressure nozzle system across the entire face of the scrubber pack at a rate of 1 1/3 gallons per minute per square foot of pack. The tank ventilation discharge**a~r** 

### is distributed across the face of the pack. The maximum velocity through the. scrubber system shall no1: exceed 400 FPM. Downstream from the s.crubber pack system will be 800 square feet of Z-frame moisture eliminators

.. This system shall be certified to remove at least 99 percent. of the soluble contaminates from the ventilation effluent air stream. (2) The total volume of paint stripping. and cleaning agents used in this process is 116,300 gallons.
b. Paint booths with scrubber, also quantity and type of paints, and paint thinners: (1)· All pain1: spray operations in building 507 will be accomplished in seven water wash type paint booths.' These booths will be four DeVilbiss Model XXW-6848, size 8' X 9' X 10' working area with 14,000 CFM exhaust fans, and three Model XSW, size 10' X 12' X 14' working area and 27,175 CFM fans. Exhaust air from'these booths will be to the atmosphere. (2) The types of paint, thinners and anticipated weekly volumes of sprayed finished are: (a) Acrylic.lacquer, MIL-L-1953-7, 15 gallons (b) Lacquer primer, MIL-C-8514, 5 gallons

. (c) Polyurethane paint, MIL-C-8328-6B, 10 gallons

(d) Epoxy base paint, MIL-C-23377C, 10 gallons (e) Polyurethane thinner,**MIL-T~81772,** 

### 12 gallons



### 4.2.4-1055

# , 

# . •

(f) Cellulose nitrate thinner, MIL-TT-T2660, 50 gallons (g) Denatured alcohol, 15 gallons

c. Type of emissions from process' ovens: There will be five process ovens installed in the landing gear overhaul facility. (1) Three eachexpansibn ovens with thru-belt conveyors to be used to thermally expand· aircraft wheels so the bearing cups can be removed. These ovens are electrically heated with a maximum. temperature of 400 0 F. No product or combustion**emission~** 

### will be generated. (2) One each paint drying oven that 

### is heated by infrared lamps to a maximum temperature of 2S0 0 F. Emissions will be small quantities 6f volatile paint thinners. (3) One each steel bake oven to be used to release entrapped hydrogen in steel aircraft components that was introduced·during. chemical cleaning.. This oven 

### is heated by natural gas firing with an' electrically 0 heated backup system.' The maximum temperature will be:375 F.and no product emissions will be generated. The only emission to the atmosphere will be the combustion by-products of the natural: gas firing system

.. d. Bag house in the mechanical cleaning area along with efficiencies, types and flow rate: There will be five bag house type dust collectors installed outside the building to support all mechanical (air blast) cleaning of aircraft parts. The parts air blasted are steel and aluminum. The blast media will be 80-180 grit alum oxide or agasite (walnut shell or cracked hard wheat). Three of these units will be 10,000 CFMcloth
screen cOl+ectors with 2,800 square feet.of filtering fabric, one 6,500 CFM unit and one 6,000 CFM unit. One 10,000 CFM unit 

### is a Pangborn CH-3 type and four are American Air Filter Corporation Fabric Pulse machines. Units are designed to comply with current OSHA requirements.

e. Melt furnaces, type of firing and control: There will be four each melt furnaces installed in the fdundry area. 'Two of these furnaces
are 1,000 pound capacity tilt type units and will be used to pour lead and Kirksite (lead zinc**copp~r** 

### alloy) drop hammer dies, with a maximum temperature of 1,0000F. Two'furnaces of 250 pound capacity will be used for aluminum and brass .casting. These units are fired by natural gas and forced air draft. All controls**~re** 

### automatic. The only emissions· from these units will be the products of combustion from natural gas and forced air draf
