December 20, 1988 Thayne Judd, Colonel United States Air Force Headquarters Ogden Air Logistics Center (AFLC) Hill AFB, Utah 84056-5149 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 paintsIsolvents 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.

4.2.4-894 AIR QUAUTYNOTICE 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 400C and ideal behavior is applicable. Waste paint material recycled 20,000 gals/yr Assume saturated air displaced

### 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 isfed intothe 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 withintheboiling 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 boilerorthermal oil system. Vapors Condensed Afteratime penodthesolventwill boil and producevaoorswhich nse and leave the heatchamberthroughthevaportube into the conoenser. This air or water-cooled condenser will restore the vaoors to a liquid state. Tne clean. clearsolventthen gravity flows into a 55-gallon drum or automatically intoan existing S!oragetank. 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 byiour rotating seraoer blades ana our exclUSive VISCOSity monltor/reclrculalion system until reaay 

# ,0 gravity drain into astandard 55-gallon drum. Automatic Shut-off Should thesupplyof solventterminate in the automatic operation, the unit will simply reclaim downto alowlevel 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 ratherthan integral steam coilsand does not require scraper blades. The unit processes uo to 200 gallons per hour.
