EPA Federal Facilities Toxic Release and Reduction
Initiatives Fact Sheet
Background
Executive Order 12856, entitled "Federal Compliance with
Right-To-Know Laws and Pollution Prevention
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 report:
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.
This Fact Sheet contains two charts and four main sections:
• The charts represent the waste management distribution and percent change of TRI reported quantities.
• Chemical Profile section
• Identified and used P2 approaches section.
• On-going P2 research and development section
• P2 research and development/transition needs section

Forty-tour Federal facilities reported releases of xylene m their 1994 or 1995 TRI reports The
largest leasers were NASA Kennedy Space Center (7% of the total 1994 reported release of
xylene) and the US Marine Corps. Barstow (also 7% of the total for 1994)
Xylene is used as a solvent, as a raw material for the production of organic chemicals used to
make polyester fibers, and to make dyes Other uses are in stenlizmg catgut and m
micfoscopy Xylene a a by product of fuel combustion and a component of certain jet fuels (i.e.
JP-4), gasoline, paints and pamt thinners, cleaning products, and adhestves.
www epa oovrttn/uatw*http //www epa oov/ttn/uat • Exposure can irritate the eyes, nose, and throat Xylene can also cause headaches, nausea,
w* and vomiting, tiredness, and stomach upset. High levels can cause dizziness and fainting
Very high levels can cause death (source hit p.//mail odsnot com/TRIFacts)

Ftamemaster and GSA ar« current suppliers foe these sealants Results from tasting indicate the poly sulfide potting compound showed loss of
adhesion and severe shnnkage at 200 degrees F A warning label may be necessary Another concern is the possible requirement for high

• Toluene is found in many heavy degreasing and stripping products often as an additive instead of as the primary ingredient. It is a major
component in blanket wash cleaners used m lithographic printing Many Federal facilities have successfully found less toxic alternatives for
toluene in cleaning processes. In many cases, facilities have modified both the cleaning agent and the cleaning equipment Aqueous jet
washers, for example, are now commonly found at most DOO facikties. |
• Steam cabinets or vacuum vapor deg feasors will most kkely 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 emulslficttion break-down, and removal of caked-on dirt and j
grease The high temperature of steam is used to heat surfaces long enough for the steam to vaponze 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 tieanets are avail able through the national stock system. These
have been used at DOO facilities for removing oil. grease, sand. rust, carbon, and burnt propellant from weapons The wastewater generated
from the steam deaning process may be treated at an industrial wastewater treatment plant, depending on the toxicity of the dirt and grease

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 S mmHg at 72 degrees F Normally, these solvents are applied with a solvent soaked
doth, followed by a surface wpe with a dean doth In some cases, a second dean doth wipe may be required to remove residual solvent to

• 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 deamng is complete, the solvent vapors in the chamber are evacuated and captured by chiftng and carbon adsorption Once
the solvent in the chamber is evacuated, the door of the chamber is opened and the workload is withdrawn. The cleaned workload is also free

• According to statistics from the National Alternative Fuels Hotline. Federal facilities have steadily increased the* purchase of alternative fuels j
since 1993 By 1997. Federal facilities purchased 15.434 thousand gasoline-equivalent gallons up from 1,511 gaBons in 1993 Total !
consumption of alternative fuels in 1997 for Federal, state and local, and private users is repotted to be 338.817 thousand gasoline-equivalent j

• DOE conducted a survey of Federal fleet managers in 1996 regarding the use of alternative fuel vehicles 40% of the manager* (106 survey |
respondents) identified compressed natural gas (CNG) vehicles as the primary AFV in their fleets (source. USOOE "Perspectives on AFVs 1996
Federal Fleet Driver Survey. POC Patnck Summers (303) 275-4050). The five vehicle models most frequently reported by the fleet managers to
be the* primary AFVs were the Dodge Spirit. Ford Taurus, Dodge Caravan, Dodge Ram Van, and Chevrolet Lunmna Fleet managers were
asked whether drivers of the* fleet vehicle# specifically want AFVs. More than 65% of the managers whose primary vehicles are CNG-CON
(aftermarket conversion). E85, and M85 vehicles said their drivers are neutral about AFVs By contrast. 44% of the respondents whose primary j
AFV type » CNG-OEM (original eqwpment manufacturer) indicated their drivers do not want to drive them 42% of the respondents reported
that there was not an alternative fuel station reasonably dose by Fleet managers operating M8^ vehicles have the least access to fuels In (
terms of vehicle performance, 71% of the respondents said that they received about the same number of complaints about their AFVs and j

• As of September 1991. the Clean Cities Program had created partnerships in 57 communities. Program participants have more than 30.000
operational AFVs and represent more than 2,000 stakeholder organizations (source http://www.ccities.doe gov. or call the Clean Cities Hotline
800-CCITIES) Efforts to transition to AFVs are also underway at the municipal and State level, in many cases, the USE PA and DOE are
playing a coordinating role EPA Region 111 has launched a Green Communities program which includes an energy conservation component
(source http //www epa gov/regtonOS/greenkit).
• The Energy Policy Act of 1992 requires the Department of Energy to establish a program that promotes the replaoement of petroleum based
motor fuels to the maximum extent possftie DOE'S program consists of five major elements 1) establish a strong foundation for alternative
transportation fuels. 2) secure voluntary commitments to bring the neoessary AFV infrastructure, supply and demand on-line simultaneously. 3)
develop incentive programs to stimulate investment in alternative fuel vehicles and supporting infrastructure through Federal tax incentives and
grants to states. 4) secure fleet leadership from Federal fleets, state fleets, and alternative fuel provider fleets. 5) examine whether it is
technically and economically feasible to attain the petroleum displacement goals laid out in the Energy Policy Act within the statutory time limits
Some of the maior program initiatives supporting me adoption of AFVs are the Clean Cities Program, and the Alternative Fuels Transportation
Program (source US OOE "EPACT Initiatives for Alternative Fuel Vehicles an integrated strategy for «nplementing the Energy Policy Act"
