Case Study: Romo, Inc.
By Jon Weber, Quality Manager, Romo, Inc.

Federal and state environmental regulations have become more strict each year,requiring businesses to
find ways to reduce or eliminate the pollutants they are putting into the atmosphere and the harmful
chemicals that they use daily, or suffer the consequences. The following is a story of how a small
company reduced its waste voluntarily by 90% over the span of a few years, and has received national
recognition for it.

33/50 Pragram Background

The Environmental Protection Agency’s (EPA) 33/50 Program is a voluntary pollution reduction
initiative that focuses on 17 different Toxic Release Inventory (TRI) chemicals for reduction in direct
releases (through the air, etc.) and off site transfers (in your hazardous waste barrels). This program gets
its name from the goals that it set - a short term reduction of these TRI chemicals of 33% by 1992, and
an ultimate reduction of 50% by 1995, using 1988 TRI reports as a baseline. About 1,300 companies
responded to this initiative that focused on voluntary pollution source reduction. The goal of the
program was to reduce the 1.5 billibn pounds of pollution reported to TRI to 750 million pounds. By
1994, the 33/50 Program led companies to decrease the chemical pollution by 757 million pounds,
beating the goal by 1 year.

                     THE 17 TFU CHEMICALS OF
                     THE 33/50 PROGRAM

                     CADMIUM & COMPOUNDS
                     CARBON TETRACHLORIDE
                     CHROMIUM & COMPUNDS
                     LEAD & COMPOUNDS
                     MERCURY & COMPOUNDS
                     METHYL ETHYL KETONE
                     METHYL ISOBUTYL KETONE
                     NICKEL & COMPOUNDS
                     1,1,1 - TRICHLOROETHANE
    The company’s next step was to address the use of emulsion remover. In the past, employees dipped a
    brush into the emulsion remover container and then used the brush on the screen to remove the
    emulsion. To gain efficiency in this process, a spray nozzle was connected to the 15-gallon container so
    that an employee could evenly mist the screen with the emulsion remover. To speed up this process,
    Romo installed a high-pressure water blaster (290 psi) to spray the screens. This increased pressure did
    not degrade screen quality. Additional pressure (1,500 - 4,000 psi) proved overall more effective. The
    increased pressure aiso cut back on the amount of emulsion remover needed, going from 1 gallon for
    every 3 gallons water to 1 gallon for every 6.5 gallons water. By using a water/emulsion remover
    solution, the company was able to cut back on emulsion remover use by 75%. This reduction resulted in
    a $3,80O/year savings, allowing the $4,900 pressure washer to pay for itself after only 15 months.

    With only a few minor process, product, and equipment changes, Romo was able to easily reach its
    33/50 Program seal. By 1993, the company’s total TRI release goal was 20,368 (33% less than the
    1988 figures) pounds, and by 1995, the company’s goal was 15,200 pounds. By the end of 1992, the
    actual amount of TRI chemicals released was 5,390 pounds, 10,000 pounds less than the overall goal
    and 3 years ahead of schedule.

    After 3315.9 .   ~       -   ^   -

    Romo’s releases held steady for about 3 years, with no drastic process or product changes. However, in
    the silmmer of 1996, Romo management wanted to find a new screen wash product in order to stay
    proactive and to reduce chemical releases even further. A “Solvent Team” was created with production
    employees who use the solvents on a daily basis. This team tested a number of company’s products in
    actual production environments, in some cases for 2 to 3 weeks at a time. The team collected data on
    each product batch, including how much was used, how easy the product was to use, and whether any
    changes in the recommended application procedure were required. The Solvent Team met on a weekly
    basis to discuss test results and to plan future testing. The group also studied MSDS sheets of the
    products tested so that Romo did not take an accidental step backward when it was trying to go forward.

    After a couple of months of testing, the solvent team chose one company’s products. While certain
    situations still require the use of the old solvents, the new product line has virtually replaced the old
    solvent. A new organic solvent mixture, which contains no SARA reportable ingredients, replaced the
    press solvent that employees had used since 1992. This new product separated the ink from the screen
    mesh whereas the old solvent packed the ink into the mesh more. In essence, the new product
    significantly decreased the number of screens that needed to be hazed to 5% overall.

    Romo also switched its screen wash solvent and eliminated the need for the still. The new screen wash.
    like the press solvent, contains no SARA reportable ingredients. The screen wash system now uses. a
    recirculation tank that reuses all solvents that do not fall directly on the screen. The tank reuses all
    solvents drained into it. Finally, Romo switched its emulsion remover to a product that contains no
    reportable chemicals.

     Along with the product changes Romo made, employees needed to make equipment and process
    changes. First, Romo covered its overhead lighting (which contained ultraviolet light) with an UV
    inhibative material so that light from the ceiling would not dry the UV ink into the screens, which
    promotes screen hazing. Second, when employees need to leave their press for any reason, they must
    wash the substrate side of the screen with the press wash to prevent ink from drying into the mesh. The
    p r o d u c t k d prmxss changes dramatically reduced screen hazing. When Romo made their most recent
    product and process changes, the percentage of screens hazed dropped from 33% of all screens to 5 % ,

Manage inventories on a first-in, firstaut basis.
  This will minimize the disposal of expired materials.
Maintain accurate logs of your chemical and materials
stock, use and waste generation rates.
   This will help you evaluate your shop's materials flow and

Minimize the amount of chemicals i the production area
   This will encourage materials conservation.

   This allows wastes to be reused or recycled, and prevents

       Case Study #1:
       Beta Testing the CalComp EcoGraW lmagesetter
             Grady McCauley, Inc.. is a major screen printer in North Canton. Ohio, employing over 160 people. The company specializes in
       large format, point-of-saledisplays and fleet graphics.
             For the past year, Grady McCauley has been beta testing the CalComp EcoGrafiP digital dry film imaging system. This system
       allows Grady McCauley to produce film positives for complex line art and multicolor applications. Positives can measure up to 36
       inches wide, with a dpi range of up to 400.
             In addition to the EcoGrafix@     generated positives, the company also generates some Rubylith" positives using a plotter. A small
       number of photographic positives are still generated and tray developed. and four-color positives over 36 inches wide (a relatively small
       number of positives) are out-sourced.
             Dennis Grady. CEO of Grady McCauley, notes that the company has been successfully using the EcoGrafix" digital system to
       generate approximately 40 to 50 positives per week. By using the EcoGrafix" imagesetter along with a smaller number of plotter-
       generated Rubylith" positives. and out-sourcing photographic positives over 36 inches wide. Grady states that his facility has been
       able to reduce photographic wastes to Very negligible fractions of gallons per week."
             Grady observes that his main incentives to move to the EcoGrafiP system, however, were the advantages of digital flexibility and
       the fact that CalComp offered a format up to 36 inches. This allows the company to output to a full size positive that does not require
       resizing. meaning that they can..eliminate all the prepress work that a photographic positive resizing entails.
             In addition, digital flexibility allows the prepress specialist to work with text and graphic design to the limits oEhardware and
       software capability while producing a positive that is ready to image the screen, in a size that fits the needs of a largrzformat screen
       printer. This flexibility and increased productivity allow for significant savings in labor, making the cost of implementingthe CalComp
       system (around $35.000)a viable investment.
             The biggest challenge with the digital system, according to Grady, has been in the refinement of prepress technique. He states,
       "getting good, predictable resolution, density and sharp edges in both the black and four-color process work" took some time and effort
       to perfect. However, continued refinement in technique and practiw inmrbingwilh.the q s i p r s t iapqmp&rGsid@cGauley.
       The company is realizing increased productivity and enjoying the added benefit of nearly eliminating the generation of hazardous
       silver-bearing wastes from the prepress process.

    and placards, using enamels. Keeping the small business competitive is of prime importance to Sarjeant.
          Competitive concerns have led the company to switch from a diffusion transfer positives generation process using a laser Printer
    to a silver halide imagesetter. Sarjeant was originally using a laser printer to generate about 175 to 200 digitally produced images per
    week. But he was not pleased with the quality of the digital products.
          In addition. each one of the positives was produced on a single sheet of paper that was then taken to a camera operator for the
    preparation of a film positivo. The film positive was produced through a diffusion transfer process. This process eliminated silver halide
    chemistry, but it generated only a 60 Ipi, 600 dpi positive that sometimes performed poorly in regard to blends and tints. Additionally, the
    operators shooting the film positives for each individually generated digital image spent approximately half of their working day on this
    task alone.
          After investigating his options. Sarjeant came upon the CompuGraphics 94OOa imagesetter. This imagesetter uses silver halide-
    based films and chemical development processes. However, it delivers the 175 to 200 positives per week that Daytona produces at up
    to 1,200 dpi. This produces noticeably sharper blends and tints. The film for the imagesetter also comes in prespooled standard sizes
    that allow Safjeant to schedule positives production and shoot up to 25 linear feet of film before developing. This eliminates the need
    to have one prepress person devoted to image transfer for four hours per day and greatly increases productivity.
          Sarjeant investigated waste disposal costs and issues and found that adequate silver recovery services were available in the
    Daytona Beach area. Reclaiming his liquid silver wastes (lessthan five gallons per week) and tilms has allowed him to realize a net
    savings when increased productivity. quality, and time savings are considered.
          While this system has been a 'Volkswagen to Lamborghini" improvement according to Sa .eant, he is still keeping his eye on
    emerging silverless digital technologies. He notes that equipment such as the CalComp EcoGrafi and the LaserMaster laser printers
    are making strides to improve Ipi and dpi ranges.

        Basic RCRA Recordkeeping Requirements For Printers
The Resource Conservation and Recovery Act (RCRA) of 1984 gave the U.S. Environmental Protection
Agency (EPA) the authority to regulate municipal and hazardous waste. The purpose of this fact sheet is
to provide a basic understanding of the various recordkeeping requirements mandated by EPA.
Depending on state and local requirements, additional recordkeeping requirements and longer record
retention reqltiPerPreaAtsawq”p1y:- -- -

The information below in a starting point for determining if your RCRA required records are in order.
Since paperwork is one of the easiest noncompliance issues to spot during an EPA audit, keep your
paperwork in order. Here are some records to keep.

e       EPA Identification Number / Notice of Hazardous Waste Activity (40 CFR 262.11)
Prior to offering hazardous waste to transporters or treatment, storage, or disposal facilities a generator
must obtain a EPA (waste generator) identification number. The facility must complete EPA form
870012 and submit it to the Agency. Copies of the application and notificatiordassignment of the facilities
assigned identification number must be kept on file. No specified record retention period. Note, this
number does not expire or change, unless the facility relocates.

         Hazardous Waste Storage and Accumulation (40 CFR 262.34)
Facilities that generate greater than 221 Ibs per month (SQG & LQG) of hazardous waste are required to
train affected employees on proper waste Mdling and emergency procedures, maintain documentation
on waste handling procedures, which includes designated emergency response personnel; documentation
on duration and date of waste storage, and a written storage time compliance procedure. No specified
record retention period.

e        Manifests and Land Disposal Notification (40 CFR 262.40)
Facilities that generate greater than 221 Ibs per month (SQG & LQG) of hazardous waste are to maintain
copies of each signed manifest. One copy should be retained when the waste is transported from the
facility and the second copy must be signed and supplied by the disposal facility within 45 days after the
waste leaves the generator’s facility. The facility’s manifests or the signed manifests from the treatment
storage and disposal facility receiving the hazardous waste are to be retained for 3 years.

Records of test results, waste analyses, or other determinations that the waste is hazardous must be kept
for 3 years.

       PNEAC Fact Sheet: Basic OSHA Recordkeeping & Training Requirements Affecting Printers p.2

       0       Biennial Report (40 CFR 262.41)
       A Biennial Report (each even numbered year) must be submitted to the USEPA by Small Quantity and
       Large Quantity Generators no later than March 1"' (on odd numbered years most states require a report
       be submitted to the state agency). A copy of the Biennial Report and Exception Report must be kept for
       3 years.

       0       Exception Reporting (40 CFR 262.42)
       If the hazardous waste generator does not receive a signed copy of the manifest from the disposal facility
       within 45 days after the waste was accepted by the initial transporter, an Exception Report must be
       supplied to the state regulatory agency and a copy of this report must be retained w i t b h e manifest. The
       exception report must be retained for at least 3 years.

       present ar?d hture threat to human health and the environment; OR, if I am a small quantity generator, I
       have made a good faith effort to minimize my waste generation and select the best waste management
       method that is available to me and that I can afford." In other words a waste minimization and pollution
       prevention plan is required to be implemented. It is recommended that a written program be developed
       and retained on-site.

              Hazardous Waste Storage Area Inspection (40 CFR 265.1101)
       The hazardous waste storage area must be inspected at least every 7 days to monitor leak detection
       equipment and detect signs of releases of hazardous waste in or around the containment area. Records of
       weekly inspections must be maintained for at least 3 years.

       manifests when material is being transported for reclamation. Persons who store these materials
       (nonspeculatively) must keep records showing the volume of these materials stored at the beginning of
       the calendar year; the amount generated or received during the calendar year; and the amount of materials
       remaining at the end of the calendar year. No specified retention period for the documents.

       0      Used Oil Generators (40 CFR 279.74)
       Generators of used oil are to keep a record of each used oil shipment that is accepted for
       processinghe-refining and shipped to a used oil burner, processor/re-refiner, or disposal facility. These
       records may take the form of a log, invoice, manifest, bill of lading, or other shipping documents.
       Records are to be retained for 3 years.

PNEAC Fact Sheet: Basic OSHA Recordkeeping & Training Requirements Affecting Printers p.3

       Underground Storage Tanks (UST's) (40 CFR 280 & 281)
Owners and operators of new and existing USTs are to maintain records that demonstrate compliance
with performance standards (monitoring, testing, protection, repairs, and closure). These records are to
be maintained for the life of the tank and piping system.

     How to Read and Use an MSDS for Environmental Purposes
 OSHA mandates that each product used commercially which contains any hazardous ingredient must be
 accompanied by a Material Safety Data Sheet or MSDS upon entering a facility if there is one or more
 people employed at that location. The MSDS was initially designed to convey important safety hazard
 information and measures to protect persons who may come in contact with a product, including
 employees, fire fighters, etc. Current, revised, and obsolete MSDS must be kept on file at a facility for 30
 years or as long as the company is in business (whichever comes first).
- -

 The MSDS also sewes to provide important environmental compliance information, including VOC
 content, hazardous chemical ingredients and their CAS numbers, product density, and vapor pressure.
 This information is required for hazardous air pollutant (HAPS) and VOC emission calculations, as well
 as other annual record keeping and reporting requirements, such as S A R A 3 1 1 and 3 12 reporting

There is currently no required format for a MSDS, but the most common is the OSHA Form 174 which
contains 9 different sections. Other formats may illustrate the same required information, but in an
alternative lccation on the sheet. This guide follows the same sequence as the OSHA Form 174. Each
section of OSHA Form 174 is listed and environmental information or description is provided where

Section I. Basic Product Information

1. Trade Name or Synonym.
This name may not reflect the product’s use or the name the product is referred to in your facility. It is
recommended that the facility mark on the MSDS the department or application of the product if it is
unclear on the MSDS.

2. Manufacturers Name and Address.
This may be different than product source or supplier. It is advised that if the product supplier is different
write their name and phone number on the MSDS sheet.

3. Emergency Telephone Number.
There must be 24 hour telephone access to a company representative in case of a spill, reiease, or
personal injury. Many suppliers of hazardous materials contract out to an emergency answering service
provider such as Chemtrec.

4. Chemical Name of Product.
              PNEAC Fact Sheet: How to Read and Use an MSDS for Environmental Purposes p.2
       Refers only to products that are single substances, such as methyl ethyl ketone. This information may be
       sanitted ifthe product is a mixture or proprietary.

       5. Date Prepared.
       Signifies the date the original MSDS information was compiled or last updated. This information should
       be used to verify whether a new MSDS has been updated or is a duplicate of current MSDS on file.

       6 . Signature of Preparer.
       Optionai information, name andlor signature of the person who prepared the MSDS.

       Section TI: Hazardous Tnoredients

       This section lists the chemical name, CAS (chemical abstract service) number, and the quantity of the
       chemical within the product expressed in percent by volume or weight. This informationris needed to
       calculate the chemical usage and storage quantities for SARA Section 3 11,3 12, and 3 13 compliance as
       well as calculating HAPSand VOC emissions from the product for air p e - ~ t t i n calculations or quantity
       of chemical released. Some state air operating permits specify how the VOC information must be
       calculated and the printer may need to work with the supplier to provide the VOC information i then
       correct units of measure.

       Many MSDS omit the VOC containing products in this section, but will list the total volatile content of
       the product. The printer will need to consult the supplier to obtain a product data sheet which provides
       information about the actual chemical and its concentration that is a VOC.

       A supplier may list chemical content as a range due to proprietary concerns, for example 10-15%. In this
       case the printer should verify the VOC content with the product supplier. If the actual VOC content
       cannot be verified, consider the higher percentage when caicufating total concentration of VOC or HAP.

       VOC emission calculations and certificaiion that the information is correct is the responsibility of the
       printer. In other words it is the printer's responsibility to verify that the VOC information that the supplier
       provided is correct. One way to assure that the information is correct is to request that the supplier
. .'
       determine the,VOC: content of their products through EPA Test Method 24 or Method 2 4 4 which are ,
       analysis protocols for determining VOC content of liquids established by U.S. EPA.

       Section lII: Phvsical Data

       1. Boiling Point:
       The temperature in degrees F at whch a liquid boils under normal atmospheric conditions.

       2. Vapor Pressure:
       The pressure of saturated vapor above the liquid in mercury at 68 degrees F.

       Boiling point (bp) and vapor pressure (vp) indicate how rapidly the material evaporates or how much
       VOC and HAPSare in the product. For example, Isopropyl alcohol has a boiling point of 180 degrees F
       and a vapor pressure of 33 mm Hg. Where as ethylene glycol has a&g,a&?ZL&grees F and a vp of 0.1 . -

       PNEAC Fact Sheet: How to Read and Use an MSDS for Environmental Purposes p.3
mm Hg. Products with a low boiling point, vapor pressure and vapor density typically are high VOC
products. Some state air regulations limit the vapor pressure of certain printing products, such as blanket
wash or fountain solution (used in offset printing).

When considering alternative products in order to reduce VOC emissions, the vapor pressure of a
solution is a key factor. It is best to select products with low VOC and no or low HAP content andlor
products with a vapor pressure of 10"        Hg at 20 C or less. A product which contains 100% VOC, but
has a vapor press of 10" of Hg at 70 at 20 C will emit approximately 30% VOC's by weight because
the product does not evaporate as quickly.

3 . Vapor Density:
The weight of a vapor or gas compared with an equal volume of air measured at 60-90 degrees F.

Vapor density indicates whether the vapor is heavier or lighter than air. With flammable materials, when
the vapor density is greater than one, vapors will tend to move or collect in a low spot. Flame sources
should be carehlly controlled or avoided in these areas. For example the vapor density of isopropyl
alcohol is 2.07, propane is 1.52, and helium is 0.1 114; which means P A and propane are an immediate
fire hazard because the gas can collect in low spots within a building and easily ignite.

4. Soiubility in Water:
Indicates how quickly the material combines with distilled water at 50 F. It is measured in the following
        Negligible    less than 0.1%
        Slight        0.1 to 1%
        Moderate       1 to 10%
        Appreciable more than 10%
        Complete      in all proportions

5. Specific Grzvity
This is the ratio of the density of a material to the density of water. In other words, it compares the
weight of water to the weight of material. This information is especially important in the event of a spill
which can reach a lake or stream.

6. Evaporation Rate
This the rate the material evaporates compared to either butyl acetate or ethyl ether

7. Appearance and Odor
A brief description of the material. Ex. viscous colored liquid with ammonia odor

8. Percent Volatile by Weight
This information may not be included (required on old format); the printer may need to ask the supplier in
writing, to include this information on a 1 MSDS or provide a product data sheet.

 This is the total VOC content of the product. This number should correspond with the sum of the VOC
-products listed in Section 11. This number should be used to calculate th-missions           of the
       PNEAC Fact Sheet: How to Read and Use an MSDS for Environmental Purposes p.4
product. This is calculated by multiplying the total pounds of material by the %VOC content listed (or gal
product x density x %VOC). Some state air regulations limit the VOC content of products commonly
used by printers.

For S A R A reporting purposes each reportable chemical listed, the printer must calculate the amount
consumed or stored on site by the % content listed in the health hazard section. The total amount (in all
mixtures and pure form) stored or consumed on site must then be compared to the reporting limit. If the
reporting limit for any &quot;listed&quot; chemical is Zess than what was consumed or stored on site
during any month or calendar year reporting requirements may apply.

Section TV: Fire and Exdosion Data

1. Flash Point
The minimum temperature in degrees fahrenheit, at which a liquid gives off enough vapor for the material
to auto ignite. The most common test method is the closed cup method.

2. Flammable or Explosive Limits
The range of gas or vapor concentrations (percent by volume in air) which will bum or explode if an
ignition source is present. This is expressed as the lower explosion limit or LEL and the upper explosion
limit or UEL.

3. Extinguishing Media
Lists the fire fighting media suitable for use on the burning material. Some chemicals may negatively react
to water which is the most common extinguishing media. Therefore alternative methods, such as carbon
dioxide may be more suitable for extinguishing the flames.

4.Special Fire Fighting Procedures
This includes information about the toxicity of combustion products, any special personal protective
equipment, etc.

5. Unusual Fire and Explosion Hazards
This describes any special potential hazards which may need attention. For example, if water is
improperly applied to a flammable liquid with a flash point greater than 2 12 F, a violent boiling reaction
could occur.

Section V. Reactivity Data

1. Stability
Indicates whether a chemical is stable or unstable under reasonably foreseeabie conditions of storage, use
or misuse. If unstable, the potential reactions will be listed.

2. Incompatibility
Lists chemicals and compounds that will negatively react with the product and should not be combined or
stored. This is important to review prior to use and/or disposal. Shop towels and waste storage
containers are one of the more common areas where incompatible -   -              advertently combined
            PNEAC Fact Sheet: How to Read and Use an MSDS for Environmental Purposes p.5
     and a negative reaction occurs.

     3. Hazardous Decomposition or By-Products                 ---- -
     Describes the products produced as a result of heating, burning or oxidizing. For example, thermal
     decomposition of vinyl chloride plastics produces carbon monoxide (CO), carbon dioxide (CO2) and
     hydrochloric acid (HCI)

     4.Hazardous Polymerization
     Describes the products that may be produced as a result of combining/exposing incompatible products.
     For example combining chlorine (bleach) with ammonia will produce hydrochloric acid.

     Section VI. Health Hazard Data

     1. Routes of Entry
     Ways the material could enter the body.

     2. Health Hazards (acute and chronic)
     Potential over exposure affects that will dissipate when moved away fiom product (acute) and potential
     health affects resulting fiom repeated, long term overexposure which leads to symptoms that remain fom
     greater than a few minuteshours (chronic).

     3. Carcinogenicity
     Indicates whether or not the product is known or suspect cause of cancer.

     4.Signdsymptoms of Exposure

     5 . Medical conditions generally aggravated by exposure
     Lists potential medical conditions which will worsen as a result of exposure to this product.

     6 . Emergency and First Aid Procedures.
     Recommendations on how to treat victims of over exposure.

     Section VU: Spill and Leak Procedures

A, Air

[ ] Annually prepare detailed facility wide emissions inventory which includes emissions of Volatile
    Organic Compounds (VOCs), Hazardous Air Pollutants 0 s ) Nitrogen Oxides (NOx), Sulfkr
    Oxides (SOX) ,Carbon Monoxide (CO) and Particulate Matter (e.g., paper dust or uncontrolied ink oil
    emissions), Emissions should be determined for both actual and potential emissions. Sources of
    emissions include film and plate processors, some proofing systems, printing presses, bindery lines,
    cyclones, bailers, boilers, dryers, furnaces, and other fuel combustion equipment. Emission
    detenninations can be based on either test data or mass balance incorporating appropriate engineering
    estimates and emission factors.

[ ] Determine thresholds for registration, constructioxhstallation and operating permits for existing
    operations which could be equipment specific (e.g., press, control device, or boiler) or facility-wide.
    Many statefiocal permitting programs are now focusing on facility permits and not per equipment
    permits. n e thresholds for registration and permits depend upon the current attainmentjnonattainment
   cl&ifica$on of the area, specific regulations being enforced by the appropriate government agency,         -
    and the amount or rate of air pollutants being emitted. Contact statellocal agency to obtain a copy of
    permit and air p o h t i o n control requirements.

[   3   Obtain appropriate permit(s) for existing operation. Keep copies of all permit application packages
        and emission determinations.

[ ] Determine permit thresholds for installation of new equipment to existing operations. New equipment
    could inciude presses, waters, emission control devices, boilers, cyclones, evaporators, distillation
    units,and some proofing and bindery equipment. The thresholds for new equipment and processes
    depend upon the current attainmentlnonatt3inment classification of the area, specific regulations being
    enforced by the appropriate government agency, and the amounthate of air pollutants being emitted.
    Contact stateflocal agency to obtain a copy of permit and air pollution control requirements.

[ ] Obtain appropriate permit(s) for existing operation. Keep copies of all permit application packagos
    and emission determinations.

[ ] Detennine thresholds for modifications to existing equipment that would require a permit amenGimt.
    Modifications to existing equipment includes changes in materials used (e.g., inks,dampening
    solutions, coatings, cleaning solvents, and other chemistries), increase in operating speeds, or matmal
    application rates. Keep copies of all correspondence and subsequent permit amendments. Modifica: ,on
    do not need to lead to an increase in emissions especially if an existing permit dictates the use of
    specific equipment, throughput rates, materials or chemicals. AI1 emission increases need to close$

      Document all actions taken to reduce or eliminate emissions. Reductions could be generated by
      changing process materials (e.g., use of isopropanol substitutes) or shutting down equipment.
      Typically, all creditable emission reductions must have occurred after 1990. Some states have specific
      forms to file for emission reduction credits. These credits can be used internally to net emission
      increases or sold to another company requiring offsets for emission increases.

      Establish appropriate recordkeeping and monitoring system. The system should be designed to allow
      for the demonstration of compliance with permit conditions and detection of potential violations.
      Permit conditions or regulations may require records of materials use, hours of operation, pollution
      control logs, temperatures of combustion or fountain solution, routine tests, etc. Depending upon the
      specific permit condition, it may be appropriate to periodically sample and test incoming materials,
      emissions, and control devices.

      File senli-annual emission reports and annual certification. Some permits, especially Title V, require
      facilities to submit reports and certification of compliance.

      File annual emission statements. Emission statements can be required of sources/facilities even if they
      are exempt from permitting. Thresholds for emission statements vary according to specific state/locrtI
      agency and attainmentfnonattainmentclassification. Some states require emission statements from
      facilities with emissions greater than 3 tons per year. Many states require them from facilities wt

      If necessary, develop and impIement (when required) an emission reduction plan. Emission reduction
      plans typically address emissions of VOCs and NOx during excessive day(s) of ozone formation.
      Cepending upon severity of ozone formation, actions taken could be minor (e.g., deiaylng certain non
      -critical operations, car pooling, keeping chemical containers closed) or major which wouid involve
      production curtailment.

      Keep records of any phone conversation, correspondence, testing, and calculations; and send all
      correspondence to any agency by retum registered mail.

B. Water Discharges

[ I   Inventory all sources of wastewater dxcharges. .

E 3   Determine fate of all sink drains,floor d a n ,processor and equipment drains and sewage lines.
      Direct discharges of wastewater are prohibited, unless permitted (see NPDES requiremeats .below).

[ I   Maintain copy of sewer connect permit or notification and other correspondence.

[ I   Annually determine total wastewater flow in gallons. The amount resulting from industrial water use
      should be either measured or estimated. Sources of information for estimating total flow include
      records indicating the volume of water purchased, other water purchased with process chemistry llke
      water-based coatings, water-based inks,film and fouitain solution concentrates, and any water
      pumped from weils. If necessary, gallons per month and day may also have to be determined.

El    Contact local publicly owned treatment works (POTW) or sewer authority for permission to dscharge
      process wastewater eauent and for permitting requirements and obtain a copy of the sewer code.

I 1 Most POTWs require silver recovery and may have specific limitations for certain chemicals, heavy
      metals, and physical charrreccrisc;iehCopper, Ammonia, pfi, COD, and BOD) contained in
      wastewater effluent. Contact P O W to determine specific limits.
[ ] Establish a system to track all permits and ensure that pexmit renewals are filed in a timely manner.

[ ] Some statesflocal POTWs require employees who operate and maintain any pretreatment equipment to
   be trained and certified as wastewater treatment operator. Contact local POTW/state agency to
   determine requirements.

[   9   Conduct testing of wastewater discharges. Permits andor sewer code may require periodic discharge
        testing and monitoring reports of effluents. Contact local P O W to determine requirements.

[ J When conducting wastewater sampling, especially during compliance determination testing, take a
    sample of incoming water to use as baseline. The preferred sampling protocol is a multiple-hour
    (ideally, 24-hour) composite sample versus a grab sample.

[ ] Establish policies and procedures to prevent inadvertent release of prohibited materials. EPA ban on
    discharging of oillgrease, materials that could create a fire or explosion, and chemicals that could
    produce toxic vapors and fumes. Many POTWs allow a small amount of oillgrease discharge, usually
    in the 50- to 100-ppm range. Some ignitables, especially those that contain less than 25% alcohol,
    could also be exempt from the discharge ban.

[ ] Permanently block all open floor drains in the fa.cility or if floor drain is necessary, provide drain
     covers. In the event of a spill, open floor d r a i n s ~ r m i d m m e a n s ~ ~ ~ ~bc l - e d ~ ~ ~ s ~
    discharged directly to the P O W and depending upon the material spilled, in a concentrated form.
    Alternately, a raised pipe or other device could be provided to prevent spilled che&stry Erom being
     released through the open floor drain.The alternate approach cannot present a tripping hazard.

[ ] Provide secondary containment for all processors or equipment using chemistry to help contain spills
    and prevent them from spreading. The secondary containment should be capable of holding at least
    110% of the volume of the contents of a single chemical container or processor. If more than one
    container or processor is included in the containment area, then the secondary containment must be
    capable of holding 150% of the volume of the largest primary contiher or 10% of the aggregate
    volume of all primary containers, whichever is greater.

[ ] Assemble and locate appropriate spiIl response and neutralization materials in prepress area.
    Materials include a wide variety of absorbents, two or three mops, mop bucket with wringer, several
    squeegees, several push brooms, traffic tape,spill-sign, small shovel, clean container with lid for
    receiving spilled materials and contaminated cleanup material, weak acids (for developer), alkali
                     ) ,
    material (for k containers, and personal protective equipment (e.g., rubber gloves, goggles, aprons,
    shoe covers, and general purpose respirators).

[ ] Discharges of more than 33 IbsJmonth of hazardous waste, especially listed ones, or any acute wastes
    mixed with domestic sewage requires written notification to local EPA office, state waste agency, and

[ ] Significant dischargers (those discharging more than 25,000 gallons/day) and occasionally smaller
    dischargers may be required to submit biannual effluent testing data and develop plans to respond to
    accidental spills and discharges. Contact local POTW to determine requirements.

[ ] File annual industrial wastewater discharge survey. Some local POTWs require annual reporting of
    industrial effluents. Some surveys can be extensive.

[ ] install and maintain backflow prevention system. Some water authorities require backflow prevention
    devices on each piece of process equipment connecte&toj”ingwater supply. Some water
    authorities require m u d testing and registration of all backflow preventors.
                                                    111- 49
[ ] National Pollutant Discharge Elimination System (NPDES) permit:

          [ ] Obtain permit for discharges of industrial and sanitary wastewater effluent, non-contact
              cooling water, and boiler blowdown water to navigable waterways (e.g., streams, creeks,
              lakes, rivers, etc.).

           [ ] Obtain NPDES stormwater discharge permit for any rain or. snow melt mnoff exposed to
               industrial activity (e.g., contaminated with chemicals) and discharged to navigable
               waterways. NPDES permits can be either group, individual, or general. Printers
               constructing shelters over sources of contamination (e.g., dumpsters) or bringing materials
         .     inside can exempt themselves from this regulation.

          [ ] If stormwater discharge permit is required, determine pollutant monitoring, sampling
              and testing requirements. Keep copies of all testing results.

          [ ] If stormwater discharge permit is required, devefop and implement pollution
              prevention pian designed to " i z e or eliminate sources of pollution.

          [ ] Contaminated stormwater discharges to municipal systems require notification to the
              municipality. Printers constructing shelters over sources of contamination (e.g.,
              dumpsters) or bringing matarids kick can-exeat;btha&~&m;1egulation.

          [ ] Establish tracking system to ensure permit renewals are filed in a timely manner.

[ ] Septicsystem:

          [   3   Ensure that all septic systems are installed in accordance with state/local requirements.
                  Permits for installation may be necessary.

          [ ] Conduct annual inspection of septic system to ensure it is operating properly. Some
              statdocal agencies require annual inspections by qualified engineers.

          [       Prohibit discharges of industrial wastewater effluent into septic system. In some instances,
                  states will allow discharges of certain industrial wastes into septic systems, but discharger
                   will typically be required to obtain aNPDES permit.

          [ ] Ifa septic system had been previously used and/or removed, keep copies of all sampling
              and test results indicating contamination wt industrial effluents. If remediation actions
               were taken, copies of all pertinent records and test results must be maintained.

[ ] Drinkingwater:

          [ ] Make sure that lead-free solder for pipes and drinkmg water fouitains is used.

          [ ] Use lead-free drinking fountains t a have not been citdrecalled for lead-lined cooling

          [ ] Water being supplied from wells for drinking may have to be periodically tested for
              presence of contaminants. This testing is usually mandatory for plants with more than 25
C . Hazardous Waste

         [ J Determine if hazardous waste is generated. A waste is any material that has been
             abandoned or discarded that is unsuitable for use without treatment or recycling. The U.S.
             Environmental Protection Agency (USEPA) has established a protocol of using process
             knowledge, chemical identification, or testing (flashpoint, pH, Toxicity Characteristic
             Leaching Procedure, etc.) to determine classification of wastes. USEPA also provides for
             many exceptions, while some state agencies do not observe the same exemptions. For
             example, in some states, silver-laden fixer must be counted as a hazardous waste, whie
             USEPA exempts it. In addition, some states regulate other materials like used oil as
             hazardous wastes. Please check with your state agency to see if they regulate materials
             USEPA does not.

        [ ] Ignitable Wastes

                [ ] A liquid that has a flashpoint below 60°C or 140°F. Aqueous solutions containing
                    less than 24% alcohol by volume are not included in this definition.

                [ ] A non-liquid capable of spontaneous and sustained combustion under normal

                [ ] An ignitable compressed gas as defined by DOT.

                [ ] An oxidizer as defined by DOT.

      [ ] Corrosive Wastes

                [ ] An aqueous material with a pH less than 2.0 or greater than 12.5.

                [ ] A liquid that corrodes steel at a rate greater than one-forth inch per year at a
                    temperature of 55'C or 130°F.

      [ ] Reactivewastes

                [ ] Normally unstable and reacts violently without detonating.

                [ ] Reacts vioiently with water.

                [ ] Forms an explosive mixture with water.

                [ ] Generates toxic gases, vapor, or h e s when mixed with water.

                [ ] Contains cyanide or sulfide and generates toxic gas vapors or fumes at a
                    pH between 2 and 12.5.

      [ ] ToxicWastes

                [ ] Requires testing by Toxicity Characteristic Leaching Procedure (TCLP)
                    for 25 organic chemicals, 8 metals, and 6 pesticides and sets threshold levels above
                    whch the waste would be classified as hazardous.

         [ ] Listed Wastes

                     [ ] Waste contains or is completely composed of chemicals fiomfour separate lists of
                         hazardous wastes. Some “F” listed wastes must contain chemicals on the list that
                         exceed at least 10% of the original mixture.

[ ] Determine generator status (e.g., exempt;smll, or large), which is dependent upon the amount of
    hazardous waste generated per month. Some states do not recognize dstinctions between exempt and
    small and between small and large quantity generaiors, thus requiring either exempt quantity
    generators to observe smallquantity generator requirements and smallquantity generators to observe
    largequantity requirements.

         f ] Exempt quantity generators are those generating less than 220 poundshonth of hazardous
             waste and less than 2.2 poundshonth of acute waste.

         [ ] Small quantity generators are those facilities who generate between 220 and 2,200
             pounddmonth of hazardous waste and less than 2.2 poundshonth of acute

         [ ] Large generates over 2,200 poundshonth of hazardous waste and/or more than

     [ ] Any material already counted once during a calendar month,’treated or reclaimed, and
         used again.

 [ ] Used oil sent off-site for disposal or recycling and not mixed nith listed hazardous waste
     and contains less than 1,000 ppm total halogens. Chlorofluorocarbon-bearing compressor oils are
     exempt, if not mixed wt other oils and recycled or reclaimed. Oils burned’either on-site or off-
     site for energy recovery that contain more than 2 ppm cadmium, 10 ppm chromium, 100 ppm
     lead, or 5 ppm arsenic must be burned in specially equipped furnaces, boilers, or incinerators
     w t scrubbers.

[ ] Any material left in containers emptied through conventional means. If a container is less than
     1 10 gallons, then one inch or 3% by weight of the total capacity is allowed in the container for it
    to be considered empty. For example, 5 5 - h i l o n drums are allowed one inch of material
    remaining in it for them to be considered empty. A five pound ink can would be allowed to have
    about one-eighth of an inch of ink in it to be considered empty. Containers greater than 100
    gallons are allowed either one inch or 0.3% by weight of the total capacity. Containers with acute
    wastes must be tripled rinsed.

[ ] For reusable shop towels contaminated wt hazardous waste (e.g., some solvents and inks),
    states may require written contractwt laundry facility; laundry uses own trucks to pick up and
    deliver shop towels; shop towels not saturated with solvent and pass paint filter test (under these
    conditions, shop towels being washed and returned should be exempt from regulation). Some

management costs are based on the
volume of solution, evaporation and
distillation may help to reduce costs.

Because evaporation releases fumes to the
air, permits are often required to operate

                        support staff who will help you locate the materials you need.
                        SGIA maintains an extensive database of product information that

                                                 voluntary effort between representatives of the screen printing industfand the U.S.
                                                 Environmental Protection Agency. The goal of the project is to provide screen
                                                 printers with information that can help them design an operation that is more
                                                 environmentally sound, safer for workers, and more cost-effective.

                                                 The DtE Screen Printing Project encoltrages the nation's 20,000 graphic art screen
                                                 printers to consider environmental and worker safety concems along with cost and
                                                 performance when purchasing materials and designing systems. The praject focused
                                                 prirxarily on the process of screen reclamation and evaluated several different
                                                 reclamation systems. Information was gathered on the performance, cost, and health
                                                 and environmental risk trade-offs of the components of each screen reclamation
                                                 system (ink removers, emulsion removers, and haze removers). The Project partners
                                                 provide this information to help printers make more informed decisions about the

                                                 WHY IS EPA WORKING WITH SCREEN PRINTERS?                                             ?

                                                 There are about 20,000 graphic art screen printing shops in the United States. These
                                                 mostly small- and mediun-sized businesses perform diverse functions ranging from
                                                 the printing of billboard advertisements and posters to printing onto electronic
                                                 equipment. Screen printing involves stretching a porous mesh material over a frame
                                                 to form a screen. Then a rubber-type blade (squeegee) is swept across the screen
                                                 surface, pressing ink through a stencil and onto the print material. In the course of
                                                 providing their services, screen printers can reclaim the screens using solvents to
                                                 remove inks, emulsion (stencils), and remnant image elements so the screens can be
                                                 used again. The use of these solvents, however, can pose potential risks to the
                                                 people who work with them and to the environment.

                                                 The Design for the Environment (DE) Screen Printing Project is a unique, voluntary
                                                 effort between the screen printing industry and the U.S. Environmental Protection
                                                 Agency (EPA) dedicated to helping screen printers prevent pollution and reduce
                                                 risks to their workers and the environment in cost-effective ways. Printers, EPA,
                                                 product manufacturers, and the screen printing trade association are all concerned
                                                 with minimizing the environmental and health risks of screen reclamation chemicals
                                                 currently used in screen printing shops. DWs goal in working with screen printers
                                                 is to help them make more informed choices, now and in the future, by promoting
                                                 the search for and evaluation of cleaner products, processes, and technologies.

                                                 HOW DID THE DFE PRINTING PROJECT GET
                                                 DfE began working with the printing industry in 1992, when the Printing Industries
                                                 of America (PIA) requested EPAs assistance in evaluating environmental claims for
                                                 products. This effort ultimately grew into two separate projects aimed at preventing
                                                 pollution in the industry, one focused on the screen printing sector and the other on
                                                 the lithography sector. Each project addresses a different area of environmental
                                                 concern in the printing process. In lithography, the focus is on blanket washes,
                                                 while for screen printing the project partners chose to look at screen reclamation.
                                                 DfE Screen Printing Project partners include the Screenprinting and Graphic
                                                 Imaging Association (SGIA), the University of Tennessee, and individual printers
                                                 and suppliers.

                                                 Technical Studies

                                                 The DtE Screen Printing Project completpd a comparison of the environmental and
                                                 human health risk, performance, and cost of 14 substitute screen reclamation
                                                 product systems and technologies. The project collected hazard and environmental
                                                 release information (Le., releases to air, water, land) on 72 different chemicals that
                                                 are found in these screen reclamation systems. With this information, the project
                                                 assessed the risks to human health and the environment posed by the substitute
                                                 product systems and technologies.

                                                 Performance was evaluated in two phases:

                                                      1 . The Screen Printing Technical Foundation's laboratory evaluated the
                                                         products under controlled conditions, and
                                                      2. Field demonstrations at volunteer printers' facilities provided performance
                                                         information under "real world" conditions of production.

                                                 Twenty-three screen printir?gshops volunteered to use the substitute product
                                                 systems for 1 month. The participating printer recorded the amount of product used,
                                                 the length of time needed to reclaim the screens, and their opinion of how well the
                                                 product cleaned the screen.

                                                 The information collected in the performance demonstration was used to develop
                                                 cost data for each of the demonstrated product systems and technologies. The Screen
                                                 Printing Project also identified simple workplace practice changes that printers can
                                                 easily and cheaply implement. In addition, new methods and technologies were
                                                 examined that might help printers improve their bottom line while reducing human
                                                 health and environmental impacts.

                                                 Business Development Center, and SGIA, the project has produced a training video
                                                 entitled Saving Money and Reducing Wnsre . The video provides screen printers
                                                 with concrete ideas on how to prevent pollution and reduce waste in their shops, as

                      Additional Technical Assistance Resources
Clean Air Act Small Business Assistance Programs (SBAPs)
The Clean Air Act Amendments of 1990 require that all States develop an assistance program to help
smaller businesses understand air pollution and air permitting requirements. Through factsheets and
publications, workshops, on-site visits and phone consultations, these free confidential, non-regulatory
programs assist thousands of businesses around the country. SBAPs help businesses answer such
questions as:

       How is your business affected by new state and federal air pollution replatiorzs?
       Will you need to file f o r an air operating permit?
       What can a small business do to comply with air pollution regiilntioiis.?

To find the Small Business Assistance Program in your state:
e      check the World-Wide Web at html
e      or call the EPA Small Business Ombudsman Office toll-free hotline, 1400-363-5888..
