HAPs -- hazardous air pollutants, VOCs -- volatile organic compounds, ODCs -- ozone depleting chemicals. What do you think of when you see these acronyms? Probably the first thing that comes to mind is your favorite cleaning and degreasing solvent. The next thing is regulations, lots of regulations that may be giving you a cause for concern. If this is so, take some comfort in the fact that you are not alone.
Right now, companies throughout Arizona and the U.S. are in the process of eliminating their use of traditional solvents such as trichloroethane (TCA), trichloroethylene (TCE), perchloroethylene (PCE), chlorofluorocarbons (CFCs, e.g. Freon TF, Freon-113, CFC- 113), methyl ethyl ketone (MEK), acetone, toluene, xylene, and methylene chloride as these solvents become subject to more stringent regulations.
With all the attention focused on these solvents and efforts to reduce their use, it seems appropriate at this time to pause and take note of the accomplishments that have already been achieved by companies in Arizona to find alternatives. Over the past few years, numerous Arizona companies have been actively looking for cleaning and degreasing alternatives and many have made considerable progress, as reported in pollution prevention plans.
By sharing their successes, as well as providing some general guidance, we hope to help some of you in your efforts to find alternatives also.
As you conduct your search, however, realize that there are neither quick and easy solutions for your cleaning challenges nor "drop-in" replacements for your traditional solvents. As we all know, these traditional solvents have been widely used because of their excellent cleaning performance in diverse cleaning applications. Alternative cleaners or cleaning methods, by contrast, typically have limited applicability, and the following approach can be taken when searching for alternatives.
First, take a good, in-depth look at your current cleaning processes to understand what you are cleaning and why. Cleaning is the process of removing soils or contaminants from the surface of a substrate, and things to look at in your evaluation are:
[1]Freon, a registered trademark name for Dupont, is used generically in this article to represent the general class of similar CFC products.
Next, consider changes that will eliminate or minimize the need for cleaning, such as process changes equipment modifications, material substitutions, or product redesigns or reformulations. Mesa Fully Formed (Mesa) installed an enclosed, automated casting machine and high efficiency gelcoat spray guns for manufacturing cultured marble, replacing a cement mixer, plastic buckets, and paint brushes, and as a result, significantly reduced the quantity of acetone used for equipment and tool cleaning.
Intel Corporation converted from ink markings of logos on some finished packages to laser marking, and eliminated the need for package pre-cleaning with Freon. Hexcel Corporation (Casa Grande), manufacturer of structural composite honeycomb core, found that by implementing improved materials handing procedures, such as wearing gloves and using plastic covering, a final cleaning of the core with TCA to remove particulates and body oils could be eliminated, while still meeting customer (e.g. Boeing) specifications.
Lambda Electronics (Tucson) eliminated the use of Freon for removing flux from printed circuit boards by switching to Alpha Metals and Kester no-clean fluxes. Microsemi (Scottsdale) requested that their supplier of piece parts for semiconductor devices ship the parts in light rather than heavy preservative oil and eliminated the internal use of silicon grease, both of which reduced cleaning requirements.
Motorola Government and Systems Technology Group (Scottsdale) switched to an inert gas soldering system, eliminating the need for cleaning of some electronic assemblies altogether, and replaced some rosin fluxes with citric acid fluxes during wave soldering, allowing the use of water for cleaning instead of TCA.
McDonnell Douglas Helicopter (Mesa) switched to a World Wide Lubricants water-soluble drawing and now uses deionized water for cleaning instead of TCA. ESH, Inc. (Tempe) switched to a Kester water-soluble fluxes for solder assembly operations and now cleans with water instead of Freon.
Sea Ray Boats (Phoenix) found that by installing a dedicated gelcoat line for each color of gelcoat, they could eliminate the need for flushing the lines with acetone between color changes. Sea Ray also modified their foam blowing equipment so that it could be cleaned with Ivory dish soap rather than TCA, and switched from a paste to a liquid wax mold release agent, eliminating the need for cleaning the molds with toluene.
Once you have done everything to eliminate or minimize cleaning requirements, next consider using a less toxic material or cleaning method for each of your specific cleaning applications. In general, alternative cleaners or methods include aqueous, semi- aqueous, and nonaqueous cleaners, and mechanical and thermal cleaning methods.
Aqueous cleaners are waterborne solutions that typically contain rust inhibitors, surfactants, or emulsifiers, and include acid, alkaline or neutral cleaners. These cleaners are generally used for wipe cleaning, or in enclosed parts washers, spray tanks or immersion dip tanks, and are followed by a water rinse stage, and sometimes a drying stage.
Semi-aqueous cleaners consist of water-immiscible solutions used in conjunction with a water rinse and include terpenes, esters, petroleum hydrocarbons, and glycol ethers. Nonaqueous cleaners do not require the use of water in the cleaning process and include high flashpoint hydrocarbon or nonchlorinated cleaners, such as stoddard solvent, kerosene, or mineral spirits, as well as alcohols such as ethanol, isopropanol (IPA), and methanol and hydrochlorofluorocarbons (HCFCs). Mechanical and thermal cleaning methods include dry abrasive cleaning with plastic media or sandblasting, and bake-off ovens.
Overall, the use of alternative cleaners or cleaning methods seems to be the preferred option for many companies in Arizona. Allied Signal Controls & Accessories (Tucson) replaced TCA and Freon used for removing flux from printed circuit boards with an Alpha Metals saponified aqueous cleaner. Anocad Plating and Painting (Phoenix) replaced TCA used for degreasing brass and steel parts with BioCat 145, an alkaline cleaner used in a dip tank.

Hughes Missile also installed five in-line aqueous cleaners for defluxing operations in circuit card assembly areas. Microchip Technology (Chandler) uses Alconox for cleaning semiconductor high-vacuum equipment parts and IPA as a surficial degreaser on semiconductor manufacturing parts instead of Freon. Mesa Fully Formed replaced lacquer thinner used for cleaning contact cement from laminated countertops with a less volatile petroleum distillate, Super Electrosafe.
Motorola Semiconductor Products Sector facilities are using an ammonium hydroxide and hydrogen peroxide solution to clean electronic parts, and Mirachem 100 for machine shop cleaning, both replacing Freon. For wafer cleaning, these Motorola facilities are using Burmar NRS1020, an aromatic hydrocarbon mixture, and for wafer drying, forced hot air, or spin drying, replacing Freon in all applications. These facilities also replaced TCA used for cleaning in the chip assembly area with Bioact EC-7R and Axarel 32.
As these examples illustrate, Arizona facilities have made progress in finding alternatives. Overall, there is a broad spectrum of alternatives available and the one you choose will depend on your specific cleaning requirements. However, a good rule of thumb to follow when searching for an alternative is to find someone who has a similar application and see what they have done. If nothing else, this may give you a starting point or reaffirm what you already have learned. As you evaluate alternatives, you will need to consider the impacts any changes will have on production, product quality, or operations, including investment (equipment, qualification and development of the process), floorspace, employee training, health and safety, and handling or disposal requirements. Also consider constraints, such as customer specifications or industry quality standards, and the technology availability and track record.
A note of caution on alternative cleaners or cleaning methods. Although some alternatives may eliminate one regulatory headache, they may create another. For instance, the use of aqueous cleaners often results in increased wastewater generation, which may require some pretreatment and a permit. Some alternatives, such as alcohols, are flammable and thus present worker health and safety concerns, and many non-ODC alternative cleaners are either HAPs or VOCs.
Keep in mind as you search for alternatives, that there is a wealth of information available on cleaning and degreasing alternatives, and the ADEQ Technical and Air Small Business Assistance Program is one resource available to help you obtain that information with its free, nonregulatory technical assistance services.

The following additional Arizona facilities now have certified Pollution Prevention Plans required under ARS Sections 49-963 and 972 (as of March 10, 1994).
As part of the Department wide reorganization in December 1993, the Pollution Prevention Unit (PPU) was reorganized to separate the regulatory and nonregulatory aspects of the state pollution prevention program. Under the previous organization, the PPU was responsible for both the regulatory facility pollution prevention planning activities as well as the nonregulatory technical assistance activities.
Under the new organization, the PPU, which is located within the Division of Waste Programs, Division Support and Pollution Prevention Section, is now responsible for only the regulatory activities related to Pollution Prevention Plans (Plan), Forms Rs, and Toxic Data Reports (TDR). The PPU:
The TAU is responsible for planning, overseeing, and conducting voluntary technical assistance activities to promote technology transfer, including:

If you own and operate a small business and are thinking of implementing pollution prevention but need financing, you may be eligible for a U.S. Small Business Administration (SBA) guaranteed Pollution Control Loan (PCL), for up to a maximum of $1 million. These loans apply specifically to small businesses in need of capital to comply with environmental requirements, and/or to otherwise prevent or reduce pollution. The SBA will guarantee loans under this program providing that a business meets the SBA's credit and collateral criteria.
Loans can be used to finance the planning, design and installation of a project defined as real property which is likely to help prevent, reduce, abate or control noise, air or water pollution or contamination by removing, altering, disposing or storing pollutants, contaminants, wastes or heat, and such real or personal property which will be used for the collection, storage, treatment, utilization, processing or final disposal of solid or liquid waste. Any related "resource recovery" property (recycling) is also eligible if the proper regulatory authority determines it to be useful for pollution abatement.
To apply for a PCL, submit to the SBA department of your bank the project plans and specifications, a written cost estimate, a copy of applicable federal, state or local environmental regulations that require an expenditure of funds for the environmental remedy associated with the project, and a statement by the appropriate environmental agency validating the environmental benefits of the project. Interest rates and other criteria of the regulator 7(a) program apply.
For more information on obtaining a PCL, contact the SBA representative at your bank, or for general information, contact Gary M. Petersen, Deputy District Director, U.S. Small Business Administration, Phoenix, (602) 640-2316.

The Pollution Prevention Unit (PPU) has been awarded a $34,850 grant from the EPA Stratospheric Protection Division, entitled "Methyl Bromide Replacement Strategies". Methyl bromide is an ozone-depleting chemical scheduled for phase-out by the year 2001 under the Clean Air Act. Overall, the grant will be used to quantify the critical uses of methyl bromide in Arizona, assess the status of available alternatives, and develop a plan of action for managing the phase-out of this substance.
In Arizona, methyl bromide is used primarily for pest control during the quarantine fumigation of produce for export. As such, its elimination could have impacts on Arizona agriculture and interregional trade, especially along the border. The U.S. imparts nearly half of its winter fruits and vegetables from Mexico, and Nogales is the largest single port-of-entry for Mexican produce. Arizona produce exported to Mexico is also fumigated at the border to prevent spreading pests such as the whitefly into neighboring Sonora.
A major concern raised by the phase-out of methyl bromide is the potential for exotic pests to be introduced into Arizona or pests that may be transported out of state if replacements don't work well enough. Unfortunately, alternatives for methyl bromide may not be easy to find.
"Like with chlorofluorocarbons (CFCs) for refrigeration and 1,1,1- trichloroethane for high-tech industries, it will take a considerable effort to find something that works as well as methyl bromide for this particular uses," says PU environmental engineer and grant administrator John Hathaway. "It's a broad spectrum pesticide, it's fast acting, and when it's done its job, it dissipates into the atmosphere with nary a trace. It leaves no residue, and it doesn't harm delicate fruits or cut flowers!"
Hopefully, the research funded by this grant will identify some viable options for the immediate reduction of methyl bromide in certain applications, and at the same time establish a framework for investigating the options for the more complex applications. Overall, this approach may buy us time before the projected phase- out in 2001. For more information on methyl bromide phase-out or the grant, contact John Hathaway, PE at (602) 207-4219.

On January 3, 1994, Edward Z. Fox, Director of ADEQ, announced a proposed, waste minimization goal for reducing waste in Arizona by 25 to 50 percent by the year 2000. Under the Arizona Omnibus Hazardous Waste Act of 1991, the Director was required to establish a numeric waste minimization goal for the state by the beginning of 1994.
In announcing the goal, Mr. Fox emphasized that it was a preliminary target, and plans are underway to conduct meetings and obtain input from industry representatives, environmental groups, and the public in order to refine the goal. Based on this input and analyses by ADEQ-staff, the Director will establish a final goal, tentatively by May 1, 1994.
Some of the issues raised during the preliminary goal setting effort included what wastes or pollutants would be covered by the goal, the goal timeframe and percent reduction, how to take into account anticipated changes in the state's economy, and how to track progress for the goal. Part of the initial goal setting activities also involved an extensive survey to determine how other states that have similar goals for waste reduction, pollution prevention, or toxic use reduction established their particular goals.
Numerous states have established goals that stipulate a 25% or 50% reduction in hazardous waste generation or toxic substance usage.
The goals typically had a baseline year of 1987 or a year when reliable data on waste generation or toxics usage first became available. Timeframes for the goals varied from five years to the year 2000, and the definition of what was to be reduced varied greatly and included nonproduct output or byproduct generation (releases before treatment), hazardous waste, and Toxic Release Inventory (TRI) reported releases.
None of the other state goals were based on any rigorous analysis conducted on the part of the states, but many states cited the following studies as the basis for their goals:
At the present, ADEQ is proposing to use the TRI reported releases as the basis for measuring progress for the goal. The TRI releases are multi-media and are already tracked by ADEQ under its pollution prevention program. However, a recent announcement by EPA Administrator Carol Browner to roughly double the number of TRI reportable chemicals indicates that the use of these data for the goal may present some difficulties due to changing baseline. Questions about the goal setting may be directed to John Hathaway, PE at (602) 207-4219.

Q: Does ADEQ have grant funding available for pollution prevention projects?
A: At the present, ADEQ does not have any dedicated sources of funding available for pollution prevention projects. However, grant funding is available under the federal National Industrial Competitiveness through Energy, Environment, and Economics (NICE3), a joint U.S. Department of Energy and Environmental Protection Agency cost-sharing grant program. The objectives of this program are to demonstrate and encourage the use of less polluting, energy- efficient technologies and to promote cooperation between government and industry.
Industries must submit grant proposals with assistance from a state energy or pollution prevention office. These industry-state partnerships must cost-share at least 50% of the total project cost. Grant awards average about $250,000. Currently the ADEQ Technical and Air Small Business Assistance Unit is working with several Arizona industries on NICE3 proposals. For further information, please contact Kusuma Thallam at (602) 207-4217.
