Dear Mr. Judd: 

Re:	 Aoproval DrdeT for Two Cold Solvent Cleaning Tanks in Building 2013 

Weber County, CDS Al 

The above-!eferenced project has been evaluated and found to be consistent 

with the requirements of the Utah Air Conservation Regulations (UACR) and the 

Utah Air Conservation Act. A 30-day public com~ent period was held and all 

comments received were evaluated. The conditions of this approval order 

reflect any changes to the proposed conditions which resulted from the 

evaluation of the comments received. This air quality approval order 

authorizes the project with tne following conditions: 

1.	 Hill Air Force 3ase shall install the two cold solvent cleaning 

tanks and a 1,500 gallon waste storage tank at Building 2013 

according to the information submitted in the no~ice of in~ent

I 

I 

1. 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 Iheater ~o 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. : 

, 

.Therefore , tbtal alcohol emissions to atmosphere: 

I 

1 Gallon X I 7.4 Lbs X 5 Da.ys X 52 Wks X Ton 0.96 !on/Yr 

Day \ CallOn -W Yr 2,000 Lhs 

3. Air CleaniugiDevices: I 

No air cleaning	 devices are proposed. I
 

I


, 

4. Emission Poi*ts: , 

I 

Four 4-inch ~ents in the top of the tank ~ill discharge pollutan~ to 

the atmosphere. ' 

,
 

I
 5.	 Sample Point~:, 

i 

No sampling ~oints are an~icipated.

6. Operating ScJedule: 

I 

The proposed ~quiPQent will be operated eight nours a day, 5 days a 

veek and 52 weeks a year.

The p~opo$ed accion ?rovides for installacion of CYO (2) isopropyl alcohol 

dip clean~ng tanks in building 2013. These cold cleaning ~anks ~ill be used I

for cleaning F-16 emergency poyer uni~ (EPU) components including small tanks, 

valve co~bonencs, valve body ana ocher associated accessories. Each cleaning 

tank. will! be approxi':ll2cely 8 1 l{ X 4'-6"t.;T X 3'D, complete with vent-ilation hooc, 

an exhaust fan and a Stack. Each tank yill ~e provided ~ith a cover ~hich will be kept closed ac all times except for loadingiunloading parts. Each 

stack will exhaust approximately 2,100 cubic feec per minute (cfm) to che 

acmospher~.

2. POLLUtANT E."'1ISSIONS: 

The plimary source of air pollutan:s frOQ cold cleaning tanks is 

hydrocarb~n vapors. Using EPA Publication AP-42, second edicion, Table 4. 6-~~

the emissions from chese sources are· calculated as folloys;
