Re: Construction Approval Order 

Dea r t·1r. Lammi: 

On May 14, 1978 notice o~ intent to approve the construction of a landing gear overhaul facility at ~il1 Air Force Base, Utah was published in 

the Salt Lake Tribune. The thirty-day comment period has expired and no co~ments were received. 

This order authorizes the construction of the plant. Conditions of 

the order are that the plant will conform to the plans and specifications 

on file and the pollution control devices be kept in proper op~rating conditions. 

,. Please notify this office when the plant becomes opera'cional as a " 

final inspection is required.

.AIRCRAFT LANDlNG GEAR OVERHAUL FACILITY 

·NOTICE OF INTENT TO CONSTRUCT - ADDITIONAL INF01MJ\~ON

.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 

use in another facility, but the booth operation is the same. 

b. The ;c,ypes of paint,. thinners and anticipated weekly volumes of
 

sprayed finished are: .. . .
 

(l) Acrylic lacquer, MII.-l-1953-7,. 15 gallons 

(2) Lacquer primer, MIL-C-8514, 5 gallons 

(3) Polyurethane paint, MII.-C-8328-6B, 10 gallons 

(4) Epo~ base paint, MIL-C-23377C, 10 gallons 

(5) Polyurethane thinner, MIL-T-81772, 12 gallons

c. According to EPA publication AP-42 (Compilation of Air Pollutant 

Emission Factors) water curtains have 'little or no effect on escaping solve~

vapors but are used to stop paint particulate emissions. Water curtain 

. and sprays have paint particulate removal efficiencies of up to 95 percent. 

Using emission factors provided in AP-42 (assuming paint weighs 12. 5 pounds 

per gallon, and all of the alcohol and thinners are evaporated) the estimated 

hydrocarbons emitted from the painting operation are: 

Used/Yr Weight Wr.!ight Percent Emissions 

(Gal) Factors (Lbs) Emissions Year (Lbs)._ 

Lacquer 1040 J.2. 5 13,000 77 1O,OJO 

Paint 1040 J.2. 5 13,000 56' 7,2f30 

Thinner 3224- 8 25,792 100 25,792 

Alcohol 700 7 5,460 100 5,460 

Total: 48,542 

= 24..3 Tons 

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 4000 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 250oF. 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 

3750 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 BTUIcu 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 (~!JQ6Fi2l.. _ (Lb/Year) 

Particulates 10 79.2 

Sulfur Oxides 0.6 4.. 8 

Carbon Monoxide 4) 158.5

Nitrogen Oxides 12) 9r;;J.9

4. . 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). 

3 

4.2.4-1046 
,--'" 

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. 0.63 

nd.llion BTU per hour to melt 7r;IJ pounds per hour). Using these maximum 

capacity rates, the yearly natural gas consumption to melt the identified 

quantities is esti.mated as, follows: 

Yearly Melt BTU 6 Nat Gas 

(Tons) Reg1d (10 ) (CuFt) 

Lead ,19.5 32.5 30,400 

Kirksite 2.4.0 40.0 38,100 

Aluminum 1.9 3.2 3,050 

Brass 0.25 0.42 40Q 

,Total: 72,030

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. 

oable for heavy duty application. and where preferred 

or specified by industry and codes.

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 4000F. 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 2S00F. 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
