Dear Colonel Judd: 

Re:	 Approval Order for Paint Distillation Unit in Building 514
 

Davis County, CDS A1
 

The above-referenced 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 comment period was held and all comments 

received were evaluated. '!'he 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 

the following conditions and failure to comply with any of the conditions may 

constitute a violation of this order: 

1.	 Hill Air Force Base shall install and ouerate the two distillation 

units to be located in building 514 according to the information 

submitted in the notice of intent dated August 2, 1988. 

2.	 The total amount of nonexempt paints I solvents to be distilled in both 

units shall not exceed 40,000 gallons per 12-month period without 

prior approval in accordance with Section 3.1, UACR. Compliance with 

the limitations shall be determined on a rolling monthly total. On 

the first day of each month a new 12-month total shall be calculated 

using the previous 12 months. Records of usage shall be kept for 

all periods when the plant is in operation. Records of usage shall 

be made available to the Executive Secretary upon request, and shall 

include a period of two years ending with the date of the request. 

Usage shall be determined by maintenance of an operations log which 

shall be kept in building 514. Entries for the volumes of liquids 

distilled shall be made on a daily basis. 

3.	 Both distillation units shall be equipped with a water cooled shell 

and tube condensers. They shall operate whenever distillation is 

taking place. 

4.	 All installations and facilities authorized by this approval order 

shall be adequately and properly maintained. 

5.	 The Executive Secretary shall be notified in writing upon start-up 

of the installation, as an initial compliance inspection is required. 

?_~y future modifications to the equipment approved by this order must also be 

approved in accordance with Section 3.1.1, UACR.

This approval order in no way releases the owner or operator from any liability 

for compliance with all other applicable federal, state, and local regulations 

including the Utah Air Conservation Regulations. 

The fee for issuing this approval order is $278.56. The amount is payable to 

the Bureau of Air Quality, sent to the Executive Secretary, Utah Air Conservation 

Committee, 288 North 1460 West, P.O. Box 16690, Salt Lake City, Utah 84116-0690

Dear Mr Cordner 

In compliance with Section 3.1 of the State Air Conservation Regulations,

NOTICE OF INTENT TO CONSTRUCT
 

SOLVENT AND WASTE PAINT DISTILLATION UNITS - BLDG 514
 

1. PROJECT DESCRIPTION:
 

We propose to install two distillation units in bldg 514. A Finish 

Engineering Co's Model BCF-380, solvent distillation unit will be used to 

distill only the "exempt solvent" l,l,l-trichloroethane (TCA) and 

possibly freon. A waste paint distillation unit (not yet selected) will 

be used to distill solvents from waste paints and paint cleanup 

solvents. Both of these projects are waste reduction projects aimed at 

substantially reducing hazardous waste while recovering valuable solvents 

for recycle and reuse. Each unit comprises of a still pan with heating 

coils, a water cooled condenser, associated controls and a clean solvent 

receiving drum. Brochures from two manufacturers of this type of 

equipment are attached. 

2. AIR EMISSIONS: 

The possible air emissions from this equipment are non-condensible 

and fugitive hydrocarbon vapors displaced during filling of clean solvent 

drums. These Volatile Organic Compounds (VOCs) may consist of, but not 

limited to, methyl ethyl ketone, toluene, xylene, methyl isobutyl ketone, 

methyl cellosolve, etc. 

For calculation and estimation purposes, it is assumed that all emissions 

consist of methyl ethyl ketone (MEK). Air is saturated with MEK vapors 

as drums are being filled. Temperature of emissions is 400 C and ideal 

behavior is applicable. 

Waste paint material recycled 20,000 gals/yr 

Assume saturated air displaced = volume of material recycled. 

Vapor pressure of MEK at 400 C = 188 I:lIll Hg 

Use ambient pressure = 640 mm Hg 

188 mID Hg MEK x 20,000 Gal total = 5,875 gal MEK Vapor 

640 mm Hg Total Yr Yr 

Density of MEK Vapor: 

p

5,875 gal MEK vapor x cu ft x 6.77 Lb = 116 Lb MEK Vapor/yr 

Yr 7.48 gal cUft 

= 0.06 ton/yr 

Likewise, emissions from TCA solvent distillation unit may be calculated 

as follows: 

Vapor pressure of TCE at 400 C = 233 mm Hg
 

TCE emissions 233 x 20,000 7,281 gals/yr
 

640
 

Density of TCA 1 x 998.9 x 313 = 3.66 eu ft
 

640 x 133.4 Lb
 

Pounds of TCE emitted 7,281	 = 266 Lb/Yr 

7.48 x 3.66 

0.13 Ton/Yr 

Note: TCE & freon are exempt solvents. 

3. AIR CLEANING DEVICES: 

Hydrocarbon emissions from distillation units will be controlled by 

use of water cooled shell and tube condensers. 

4. EMISSION POINTS: 

Distillation units have no stacks. Fugitive hydrocarbon emissions 

will be exhausted via building vent fan. The vent is approximately 20 ft 

high and two feet in diameter. 

5. SAMP1E POI~~S:

No sampling points are provided 

6. OPERATING SCHEDULE: 

These units may be operated 2-3 weeks a month depending on paint and 

solvent wastes inventory on hand.

How it Works •••
 

Automatic Fill Activated 

Contaminated solvent is fed into the BCF 

boiling chamber one drum at a time or 

continuously from an existing solvent 

storage tank. 

Solvent Heated 

After a minimum liquid level is achieved 

within the boiling vessel, the heat source 

is circulated through our unique, integral 

steam coils. The heat source can be 

existing in-plant steam or produced by 

our pr~packaged stearn boiler or thermal 

oil system. 

Vapors Condensed 

After a time penod the solvent will boil and 

produce vaoors which nse and leave the 

heat chamber through the vapor tube into 

the conoenser. This air or water-cooled 

condenser will restore the vaoors to a 

liquid state. Tne clean. clear solvent then 

gravity flows into a 55-gallon drum or 

automatically into an existing S!orage tank. 

Cycle Repeated 

The process is repeated several ,Imes 

as the unit automatically cydes betv.'een 

high and low level sensors. With each 

cycie. residue in the vessel bottom will 

become more viscous This matenal is 

kept in susoenSlon by iour rotating seraoer 

blades ana our exclUSive VISCOSity 

monltor/reclrculalion system until reaay 

,0 gravity drain into a standard 55-gallon 

drum. 

Automatic Shut-off 

Should the supply of solvent terminate in 

the automatic operation, the unit will 

simply reclaim down to a low level sensor 

and shut off. In batch operation, the unit 

will shut off after each drum. 

Special Applications 

The BCF Model 600 is a special high 

output unit designed for waste solvent 

contaminated with little or no solids. 

It utilizes a twin heat exchanger system 

rather than integral steam coils and does 

not require scraper blades. The unit processes uo to 200 gallons per hour.
