Requirements", was signed by President Clinton on
August 3, 1993, The primary objectives of EO 12856 are
to encourage Federal facilities to:
•	Develop pollution prevention plans to reduce toxic
releases by 50%;
•	Collect and report data on the quantity of hazardous
materials stored, used, and released at the facility;
•	Ensure public access to use and release information.
Federal facilities are required to submit annual TRI reports
starting in 1995 for data collected in 1994,

Approach
A study was undertaken to analyze Federal facility TRI data for 1994 and 1995 to: 1) determine the most commonly
used and released chemicals. 2) identify currently used pollution prevention (P2) approaches and on-going pollution
prevention research and development to lower or substitute the use of a chemical; and 3) identify potential
RD/transition needs. As of January 1998, fifteen chemical Fact Sheets have been developed. Please refer to the
back page to order Fact Sheets for other chemicals.

CHEMICAL PROFILE: TETRACHLOROETHYLENE
CAS#: 127-18-4
SYNONYMS
TETRACHLORETHYLENE
PERK
PERCHLOROETHYLENE
COMMON USES IN THE U.S.
www. eoa. g o v/ttn/u atw#http://www.eoa.ao v/ttn/uat •
w#
Tetrachloroethyiene is used for rubber coatings, solvent soaps, printing inks, adtieswes and
glues, sealants, polishes, lubricants, and silicones,
Tetrachloroethyiene is used for dry cleaning and texi le p ~ce rig as a chemical intermediate,
and as a degreasmg agent.
ACUTE HEALTH HAZARDS
www.epa qov/ttn/uatwghttp //www.eoa gov/ttn oat
w#
Acute animal tests, such as the LC50 and LD50 tes!s in mice have shown tetrachloroethyiene
to have low toxicity from inhalation and oral exposure.
Animal studies have reported effects on the liver, kidney, and central nervous system (CNS)
from acute inhalation exposure to tetrachloroethyiene.
Acute exposure to very high levels of tetrachloroethyiene in humans has caused death. Effects
noted from acute, inhalation exposure include intense irritation of the upper respiratory tract and
eyes, kidney dysfunction, and neurological effects such as reversible mood and behavioral
changes, impairment of coordination, and anesthetic effects.
CHRONIC HEALTH HAZARDS
www..epa.Bov/ttn7uatw#http://www.epa.govrttn/uat e EPA has classified tetrachloroethyiene as a Group B2/C. probable human carcinogen.
w#
•	One human study reported that there was a potential association between drinking water
contaminated with tetrachloroethyiene and other chemicals and an increased risk of childhood
leukemia Other studies reexamined the data and did not agree with the association because
the people were exposed to multiple chemicals and the statistical significance of the incidence
of leukemia has not been resolved.
•	Tetrachloroethyiene, via inhalation exposure, has not been shown to cause birth defects or to
impact reproductive performance in animals Epidemiological studies of dry cleaning workers
exposed to tetrachloroethyiene and other solvents have shown mixed results; some studies
reported an increased incidence of a variety of tumors, while other studies did not show any
carcinogenic effects. All of these studies are complicated by potential exposure to numerous
chemicals.
•	In a study of residents exposed to drinking water contaminated with solvents, including
tetrachloroethyiene. there was a suggestion that birth defects were associated with exposure.
However, no firm conclusions can be drawn from this study due to multiple chemical exposures
and problems with the analysis.
•	Some adverse reproductive effects, such as menstrual disorders and spontaneous abortions,
have been reported from occupational exposure to tetrachloroethyiene. However, no definitive
conclusions can be made because of the limitations of the studies.
•	Animal studies have reported effects on the liver, kidney, and CNS from chronic inhalation
exposure to tetrachloroethyiene.
•	The major effects from chronic (long-term) inhalation exposure to tetrachloroethyiene in
hum3ns are neurological effects, including headaches, and impairment of memory,
concentration, and intellectual function. Other effects noted in humans include cardiac
arrhythmia, liver damage, and possible kidney effects.

HAND-WIPE SOLVENT
•	KC-135 Systems Program Office. (OC-ALCt, switched to cleaners under the MlL-C-87937 specification including DS-1Q8 for wipe-prior-so-paint
applications. They are continuing to test and evaluate other commercially available solvents including borothene and hydrofluoroethers Tinker
AFB, Oklahoma City ALC
•	Replaced 1,1,1-trichloroethane (TCA) and methyl ethyl ketone (MEK) with a terpene cleaner for hand wiping operations Martin Marietta
Astronautics
•	Replaced MEK with a cleaner approved by the KC-135 SPO at Tinker AFB. methyl-n-propyl ketone (MPK) ASC/RAS, Wright Patterson AFB
•	Isopropyl alcohol (IPA) is approved as an alternative to MEK. Technical Order 1-1-8 which references T O. 1-1-691 contains specific
procedures for the use of IPA T O 1-1-691 recommends cleaning products qualified to MIL-C-87937, Type II. Cleaners qualified to MIL-C-
87937B are the most environmentally friendly cleaners authorized for use on C-141 aircraft and its components (Reference: PRO-ACT
Technical Inquiry 8200)
HEAVY-DUTY SOLVENT
•	For heavy soil removal, NAVAIR recommends low vapor pressure (LVP) organic solvents. These solvents are volatile organic compounds, but
due to their low vapor pressures and slower evaporation rates, they may be exempt from certain air regulations and produce lower air emissions
depending on how they are used, managed, and stored. LVP solvents are generally composed of aliphatic petroleum hydrocarbons, terpenes,
esters, or organic blends with vapor pressures below 5 mmHg at 72 degrees F Normally, these solvents are applied with a solvent soaked
cloth, followed by a surface wipe with a clean cloth In some cases, a second clean cloth wipe may be required to remove residual solvent to
speed drying.
•	Nonhalogenated Systems for Cleaning Metal Parts: Production testing demonstrated the viability of spray and immersion cleaning systems for
specific cleaning applications. Based on the bench scale testing, NDCEE determined that Brulin formula 815GD is the preferred aqueous
chemistry for mechanically and ultrasonically agitated immersion systems and will be used for production testing in the Advanced Ultrasonic
Cleaning System. Daraclean 282 was selected for use in the Power Washer Cleaning System, although al! of the chemistries downselected for
the bench scale testing effectively emulsified the soils and prevented recontamination of the parts. NDCEE, POC: Richard Pirotta 814-269-
2810.
•	The Corrosion Control Element, 437 Equipment Maintenance Squadron (EMS), Charleston AFB, South Carolina significantly reduced their
hazardous waste stream by reclaiming a majority of the Methyl Ethyl Ketone (MEK) used in their aircraft refinishing operation. They did this
using an off-the-shelf recycling unit purchased from a local automobile body shop supply store. This is one example of many recycling options
implemented by Federal Facilities to reduce the disposal of used solvents.
•	Abrasive blasting is an alternative to solvents for cleaning. In the blasting process, particulate media is propelled by compressed gases or a
liquid to impinge on the contaminated surface. No toxic or hazardous chemicals are used; however, the blasting media can become
contaminated with the material being blasted from She surface. There are several different types of blasting media, some multi-purpose and
others single purpose. The various types of blasting media are: Mineral Grit/Sand Blasting. Steel Shot. Plastic Media, Plastic Foam, Dry Ice
(C02). Wheat Starch, Walnut Shells and Other Food By Products, and Sodium Bicarbonate.
•	Nonhalogenated Systems for Cleaning Metal Parts: Production testing demonstrated the viability of spray and immersion cleaning systems for
specific cleaning applications Based on the bench scale testing, NDCEE determined that Brulin formula S15GD is the preferred aqueous
chemistry for mechanically and ultrasonically agitated immersion systems and will be used for production testing in the Advanced Ultrasonic
Cleaning System Daraclean 282 was selected for use in the Power Washer Cleaning System, although all of the chemistries downselected for
the bench scale testing effectively emulsified the soils and prevented recontamination of the parts. NDCEE, POC: Richard Pirotta B14-269-
2810.
•	Hill AFB switched to terpenes and an ethyl lactate blend for aircraft cleaning operations. Hill AFB, Ogden ALC
•	Steam cabinets or vacuum vapor degreasers will most likely be used at OC-ALC for penetrant removal prior to plating. Steam cleaning is a
viable solvent alternative for removing oily or greasy residue. The heat accelerates emulsiftcaiion break-down, and removal of caked-on dirt and
grease The high temperature of steam is used to heat surfaces long enough for the steam to vaporise or liquefy the oil. grease, or dirt. The
residue can then be effectively washed away with the steam condensate. Steam cleaning can also be used with a degreasing agent (often a
surfactant) to enhance the solubility of grease in water. Steam cleaners are available to perform medium duty to heavy duty cleaning jobs and
are available in a variety of different system configurations. Portable steam cleaners are available through the national stock system. These
have been used at DOD facilities for removing oil, grease, sand, rust, carbon, and burnt propellant from weapons. The wastewater generated
from the steam cleaning process may be treated at an industrial wastewater treatment plant, depending on the toxicity of the dirt and grease
removed.
•	Switched to alternative cleaners for MEK and TCA: Pensolv L805 (a terpene-based, four part cleaner); a four part cleaner (containing MEK and
toluene), and DS-108. Commodities Directorate, OC-ALC
•	Using carbon dioxide blast media system for cleaning KC-135. C-141. B-52, B-1. and F-16 engines. C02 is used in conjunction with solvent
cleaning methods as an initial cleaning step in the process. Both G.E. and Pratt and Whitney approved the use of C02 for cleaning engines.
Additional technologies successfully implemented to replace solvent usage in propulsion include: power spray washers, water-based cleaners,
and water jet. (Reference: B. Ley "Solvent Substitution in Jet Engine Maintenance at Tinker AFB" Proceedings from the 1996 Tri-Services
World-Wide Pollution Prevention Conference"). Tinker AFB
•	Resolved by switching to terpenes and an ethyl lactate blend for aircraft cleaning operations. Hill AFB, Ogden ALC

•	Tinker AFB is installing two vacuum vapor degreasers for wax removal. Vacuum vapor degreasers release less solvent to the atmosphere
because the work chamber is completely enclosed The engine parts are placed in an airtight chamber into which solvent vapors are
introduced After cleaning is complete, the solvent vapors in the chamber are evacuated and captured by chilling and carbon adsorption Once
She solvent in the chamber is evacuated, the door of the chamber is opened and the workload is withdrawn. The cleaned workload is also free
from any residual solvent, and there are no subsequent emissions (Reference: USEPA-Guide to Cleaner Technologies Cleaning and

different DMB will be evaluated- acrylic, polymedia-lite and polymerized wheat starch. Material characterization data for comparison of the three
media will be developed from the JPATS airframe If successful, a follow-on integration project will be started in FY98. POC. WUMLSS - CTIO;

Development of NDE for Selective Stripping:
This effort is to develop non destructive evaluation techniques for determining the health of the primer or "foundation layer" that is to be left on the
substrate and to inspect for corrosion under the primer or "foundation layer." POC: WUMLSS - CTIO: MAJ W. Kevin Kuhn (937)-255-0943.
Aqueous Paint Coating & Stripping:
This Army project will design and produce new protein-based coatings for specific substrates (metals) and clean REMOVER strategy based on new
aqueous-based systems. Armament Research. Development and Engineering Center (ARDEC), POC: 201-724-6518.
Aircraft Pepatnttng Technology:	i
This program will identify the best alternatives from existing/developmental methods such as non-hazardous chemical paint strippers (i.e . no
chrome, MeCL. etc ) and mechanical procedures (PMB. Flash Lamp, dry ice, water jet, etc.). Procedure efficiency, substrate surface effects,
hazardous waste generation and A/C applicability will be investigated in order to determine the best procedure for Navy applications Comparison of
the advantages and disadvantages of each technique will also be performed Mechanical procedures eliminate hazardous chemicals, but can
damage substrate surfaces Since some aircraft skins are very thin, this is not acceptable. However, combinations of some techniques (i.e , flash
lamp'dry ice) could eliminate or minimize surface damage to an acceptable level. POC: NAWCAD, Patuxent River: Mr. Steve Hartle: (301)-342-

PAINT REMOVER
Plastic Laminate As A Replacement For Conventional Topcoats:
This Navy effort involves using plastic laminates developed by 3M as a total-body decal to replace traditional topcoats. The laminates are currently
being flight tested on F-3, F-18, and C-130 aircraft The plastic film is laminated to the aircraft's primer with an acrylic adhesive. Deiaminating an
aircraft is accomplished by using steam to release and remove the adhesive The used laminate can then be land-filled. Advantages over
traditional coatings include reduced environmental/OSHA issues associated with traditional paint booth applications, faster installation elimination
of depaint Hazardous waste and OSHA issues, lighter weight compared to typical multiple layer coatings, improved corrosion protection due to the
impenetrable nature of the plastic film, and improved survivability In addition to these advantages, commercial airline testinq of the laminates have
shown a fuel savings due to decreased drag Navy; POC Dave Pulley 301/342-8050.
Paint Stripping Methods - Autocrawler:
This program is aimed at developing an autonomous or remotely piloted vehicle prototype designed to remove aircraft coatings. The approach is to
take the existing autocrawler prototype and develop end effecter delivery systems capable of stripping coatings The end-effecters being evaluated
are 1) medium/high pressure water, 2) wheat starch, and 3) flash lamp. The program includes a prototype built for one system POC WUMLSS -

Biodegradable Plastic Media - Foster Miller (SBIR)
This effort is to develop biodegradable plastic media and an associated biotreatment system, which can be, used in current generation plastic media
blasting (PMB) aircraft coatings REMOVER processes. This could significantly reduce the amount of heavy metais contaminated waste from
stripping chromate and cadmium containing paints POC WL/MISS - CTIO; MAJ W. Kevin Kuhn (937)-255-0943.
