      POLLUTION  PREVENTION IN ENFORCEMENT SETTLEMENTS:

                          A HANDBOOK FOR EPA REGIONS



               I PURPOSE AND ORGANIZATION OF THE HANDBOOK

 The purpose of this handbook is to motivate interested agency personnel to broaden the use of,
 pollution prevention as  the  means of  correcting  violations  (i.e.,  injunctive relief)  and as
 Supplementary Environmental Projects (SEPs), i.e., pollution prevention hi exchange for some
 degree* of penalty reduction.

 This handbook follows a study1 conducted by the authors of the role of, and opportunities  for,
 the use of pollution prevention in the agency's enforcement programs.  The primary objective
 of the study was  to evaluate the inclusion of  pollution  prevention hi  selected enforcement
 settlements. Ten specific settlements-negotiated  by the EPA regions before or during FY 1992-
 were analyzed.2

 This handbook is organized into five sections. In Section II we review the concepts of pollution
 prevention,  technology innovation, and diffusion.  Section III contains a discussion of the role
 of pollution prevention in the agency's enforcement program.   Section IV contains suggested
 approaches for recognizing and creating the potential for pollution prevention in firms. Section
 V presents  strategies  that can  facilitate the inclusion of pollution prevention  conditions as
 injunctive relief or as SEPs.   Finally, in  Appendix A we present a summary of ten case studies
 of enforcement settlements containing pollution prevention conditions, case study commentary
 and  analysis.

  II POLLUTION PREVENTION, TECHNOLOGY INNOVATION AND DIFFUSION

A.  POLLUTION PREVENTION

Pollution prevention, according to the Pollution Prevention Act of 1990, is:

       the reduction or prevention of pollution at the source by any practice which reduces the
       amount of any hazardous substance, pollutant or contaminant entering any waste stream
       or  otherwise  released  into the environment  (including fugitive emissions)  prior  to
       recycling, treatment or disposal; and which reduces the hazards to public health and the
       environment associated with the release of such substances, pollutants, or contaminants.

While  pollution can  often be prevented  by changing operating practices,  the focus of this
handbook is on pollution prevention through technological change involving one or more of the
following activities:  materials substitution, product reformulation, and process modification.
Based on the above definition, Figure  1 presents the possible locations of technological change
for pollution prevention.

                             Pollution  Prevention.
B.  TECHNOLOGY DIFFUSION

Pollution prevention technological changes may be achieved either through technology diffusion
or innovation (described below).  The term diffusion is typically used to mean the widespread
adoption of existing technology, involving minor adaptation but little or no innovation. The term
technology transfer refers to diffusion between different industries or countries.  A significant
array of effective pollution prevention technology exists and can be adopted with little or no
adaptation.  Aqueous-based and mechanical cleaning  alternatives  to  organic  solvent-based
                                         II-l

-------
 systems, water-based paints and powder coating alternatives to organic solvent-based coatings,
 and water or soy-based inks as an alternative to solvent-based inks are but a few examples of
 pollution prevention technologies which are fairly well developed for many applications.

 The accessibility of technical information and assistance (e.g., through consultants and equipment
 vendors) is a critical factor in diffusing pollution prevention technology, particularly where small
 and medium-sized firms are concerned.  In contrast  to technological innovation (described
 below), as a general rule diffusion of pollution prevention technologies requires little structural
 or cultural change in the firm.
C. TECHNOLOGY INNOVATION

Innovation is the first  commercial exploitation of a new invention and can be categorized hi
various  ways.3  Major  or radical innovation represents  a significant shift in  technology;
incremental innovation involves smaller changes or significant adaptation of existing technology.
Along another dimension,  the categories termed product and process innovation  refer to the
creation of a marketable new end-product and a change in production process, respectively.  Still
another  dimension—primary versus secondary versus ancillary process change—addresses the
locus of the technical change within the manufacturing process.  A primary process is one which
yields the key functional property(s) of the product (e.g., metal casting in the case  of a  steel
bolt);  ancillary processes are,  for example,  cleaning,  degreasing, and defluxing operations.
Using the example of a steel bolt, the primary production process is the casting of the part.  An
example  of  a secondary process  is the  metal plating of the part.  Plating may provide  a
functional (e.g., non-corrosive) or aesthetically-pleasing finish, but  it is not primary to the
function of the product.  An ancillary process is, for  example, cleaning of the bolt prior to
plating.

Technological innovation is considered by many to be an important force in inducing economic
growth by increasing productivity,  opening up new markets, and helping to create new firms and
jobs.  Although technological innovation has, in some cases, created environmental problems,
research  has shown that innovation is  one important pathway to solving technology-based
environmental,  health, and  safety problems particularly  where  the adoption  of existing
technology brings only limited benefit.

      V
POLLUTION CONTROL
Traditionally, innovation designed to solve environmental problems has been both compliance-
motivated and end-of-pipe oriented. This type of innovation is quite distinct from what is termed
main-business innovation; i.e., innovation which occurs as a traditional activity of a firm, aimed
at increasing  the  firm's economic  competitiveness and  profitability.4  A firm's  pursuit  of
pollution prevention innovation,
however, may be motivated both
by  compliance concerns—over
current   and   anticipated
regulatory  standards—as well as
a desire to enhance profitability
and competitiveness  by  cutting
waste and  liability costs and/or
by opening up markets for new
processes or unproved products.
Pollution prevention  innovation
is   the    integration   of
environmental   concerns   into
main   business    innovation
activities.   This is in contrast to
pollution   control   where  the
technology    of   production
remains  essentially   unchanged
and end-of-pipe approaches are used.

Pollution prevention innovation can be directed at either reducing the environmental impact of
existing products and processes, or at creating "environmentally cleaner" substitute products and
processes.  Examples of the these two types of  innovative pollution prevention activities are
found in the case  studies.  In one .case, Casted  Metal Products Manufacturer (CMPM), the
company redesigned rinse systems for their acid cleaning, bluing, and phosphate coating areas
to reduce  water use (by approximately 100,000  gallons per day)  and wastewater generation.
These changes were significant—technically, economically and environmentally—but they did not
involve a fundamental and radical change in the product or in key manufacturing processes.„

In contrast, in the Bleached Kraft Pulp Manufacturer (BKPM) case, the company developed a
non-chlorine-based substitute  bleaching  process  to replace its  chlorine-based system.   This
process change, currently being implemented as part of an EPA consent agreement, eliminates
the generation and emission of toxic chlorinated organic compounds in the  mill's bleaching
process and the risk of chlorine exposure to workers and the public.

Industry," in Law and Contemporary Problems. Vol. 46, No. 3., 1983.

-------
The willingness and capacity of the firm to undertake pollution prevention innovation can be
affected by factors internal and external to the firm. Several factors, taken from the innovation
literature, are highlighted here.5

Internal factors include:

1.  Maturity of the firm and industry.  Some researchers have found that the firm's capacity to
innovate decreases as it evolves from a small technology-based enterprise to a high volume
producer.  In the early stages, the firm is flexible and can accommodate product and process
innovations relatively easily.  In its most mature stage of development, the  firm focuses  on
selling  a standardized product at low cost  with capital-intensive mass production equipment.
Since the cost of major innovation is high, the firm tends to make only incremental changes in
products and processes aimed at reducing cost.6 The "rigidity" of the mature firm's technology
can beget a corporate structure and attitude that can act as another barrier to technical change.

An exception to this general picture of technological development are those firms, such as the
3M Company, that produce a diverse  and constantly changing array of products.   These firms
tend to remain technologically and
managerially flexible,  resulting  in
greater capacity and opportunity for
pollution prevention innovation.
2.  Size of the
Factors Internal to the Firm Affecting the Potential
for Pollution Prevention Innovation:

•  Maturity of the firm and industry

•  Size of the firm

•  Economic position of the firm and industry

•  Markets for new processes  and products
                  Ek  Large firms
are often identified  as  the major
sources  of  innovation,  in  part
because  they tend to have larger
R&D budgets and better access to
information  on  already  existing
technology.   Innovation  at  large
firms, however, may be  hindered
by   a   desire   to  protect   old
technologies, indifference  to technological advances, and misdirected research.  Smaller firms
may have an innovative advantage through more flexible markets, dynamic and entrepreneurial
management, and better internal communication.7

-------
3.  Economic position of the firm and industry.  The financial capacity of the firm,  i.e., cash
flow and access to financing (partly an external factor) for R&D and investment, is an important
factor affecting a firm's ability to innovate.  The present economic position and future outlook
for the firm and industry are relevant factors, although they have been shown to cut both ways.
A period of growth is conducive  to technical change in general and represents a window of
opportunity for addressing  environmental concerns since pollution prevention  can more easily
be built into a new investment than be retrofitted onto existing technology.  On the other hand,
while economic recession (an external factor) or industrial decline can slow technical change
generally, research has documented increased investment in pollution prevention technologies
during such periods, motivated by a desire to cut costs.8

4.  Markets  for new processes and products.  Innovation can be stimulated by the prospect of
developing new technology or products for the market. The existence of a marketing capacity
to exploit these opportunities is critical to the success of the innovation.
External factors affecting  the  willingness  and capacity of the firm to undertake pollution
prevention innovation include the following:

1.  Regulation and liability. Strict regulation, enforced in a stringent yet flexible way9, has been
found  to stimulate innovative and efficient (with regards to energy and raw material costs)
technological changes.10   Some industry  members  claim  that  the  threat  of liability,  for
environmental  impairment (under  RCRA)  and cleanup (under  CERCLA) has  stimulated
innovation and preventive technological changes; others  suggest that the cost associated with
posting performance bonds, as required by these acts, impedes innovation.11 Liability concerns
on the  part of large firms have been translated into requirements on component suppliers to meet
certain environmental  standards  (e.g.,  hazardous   waste  reduction  efforts  or  CFC-free
manufacturing), these requirements have given some smaller supplier firms incentives to change
their technology.

Stringent regulation can stimulate technical change either within the regulated firm, on  the part
of equipment or chemical suppliers  to the regulated firm, and/or can motivate a  non-regulated
       8       OECD cited an example of this phenomenon.  In France, during the period 1974-1977, the
adoption of "cleaner technologies" was greatest in industries where there was a relative decline in investment (except
food production).  (OECD, 1985. op.cit.)

       9      Flexibility may take several forms, including:  varying length of time to comply with regulations
to permit R&D, varying strictness according to special industry circumstances,  and temporary exemptions tied to
a "contract" between the industry and the agency to carry out an R&D program in new technologies. (OECD,
1985. op.cit.)

-------
                                           Factors External to the Firm Affecting the
                                           Potential for Pollution Prevention Innovation:

                                           •  Regulation and liability

                                           •  Public and market pressure

                                           •  Technical  expertise
 firm  to   enter  the  market  with  a
 substitute product.  An example of the
 first response is the Bleached Kraft Pulp
 Manufacturer   (BKPM)   case
 (summarized in  Appendix  A).   This
 regulated mill changed its manufacturing
 technology  to  meet  effluent  toxicity
 standards.  The second type of response
 characterizes   the  development   of
 aqueous   degreasing   technology--
 developed  by equipment and  chemical
 vendors—to replace chlorinated organic
 solvent-based degreasing systems  at regulated firms.   Finally, the third type of response--
 innovation by a new market entrant-occurred when EPA phased-out the production and use of
 PCBs. Monsanto, the sole manufacturer of PCB transformer fluid, sought to find a replacement!
 for PCBs,  but could not.12 Dow-Silicone replaced PCBs with silicone-based fluid which was
 developed  originally  for other purposes but recognized by Dow-Silicone  as having suitable
 dielectric properties.  Silicone has since become one of the principal transformer dielectrics on
 the market today.  Figure 2-2 presents this model for regulation-induced technological change
 in schematic form.

 2  Public and market pressure.  Armed with data from the SARA Toxics Release Inventory and
 other sources of information on emissions and impacts,  the public is exerting pressure on firms
 to change their technology to less polluting modes of production.  In addition, a growing demand
 for lower-impact products has stimulated product and process change within existing firms and
 has created new "green  product" market entrants.   These developments are slowly creating a
 new arena of competition around  environmental  performance, resulting hi an incentive for
 technical change.                                                    ;

In conclusion, pollution prevention innovation holds great promise for solving environmental
problems and for realizing increased efficiencies or expanding markets. However, uncertainty
associated with innovative technical change can be a significant barrier to industry's willingness
to undertake it.  The firm may face technological uncertainty concerning the success or failure
of the technical change, financial uncertainty over the full cost of developing and implementing
the innovation, and market uncertainty regarding the ability of the firm to market a new product
or process along with changing market conditions. Furthermore, there may be regulatory
uncertainty,  particularly  for  firms acting  in anticipation of future  regulatory  standards.13
    12  The company's inability to find a suitable substitute may be attributable to its attempts to develop another
fluid based on the basic molecular structure of PCB (i.e., the biphenyl ring).  Monsanto's former PCB dielectric
business can be described as mature, large-scale, and automated.   According to the framework described in Section
C.l. above, a firm with this technology profile is an unlikely candidate for innovation.

-------
Innovation is risky, but larger returns (measured both in dollars and environmental improvement)
over diffusion-driven pollution prevention can be realized only with some risk taking.

3.  Technical expertise.  Technical change for both main business and environmental purposes
requires that the "problem space" of the engineer and scientist expand to include environmental
concerns along with performance and cost considerations.14  This mode of thinking has not yet
been widely embraced by universities, treating environmental concerns as a design problem that
is separate from the manufacturing process itself.

          Ill THE ROLE OF POLLUTION PREVENTION IN ENFORCEMENT

 Pollution prevention is one of the major priorities of the United States Environmental Protection
 Agency (EPA).   In June 1989, the Office of Enforcement issued  its Pollution Prevention
 Strategy.  The strategy identified several methods by which enforcement could be used  to
 promote the agency's pollution prevention goals.  The primary tool is  through the settlement
 process.  While the agency has relatively little statutory or regulatory  authority  to  require
 violators to implement pollution prevention technology, the settlement process provides a mutual
 opportunity for both the agency's negotiators and the violators to consider pollution prevention
 as part of the overall settlement process.

 By early 1991, the Office of Enforcement (OE) had issued  an Interim Policy on the Use of
 Pollution Prevention Conditions in Enforcement Settlements and  a Policy on the Use of
 Supplemental Environmental Projects (SEPs) in Enforcement Settlements (called the "Pollution
 Prevention Enforcement Policy" and "SEP Policy", respectively, for short). Together, these two
 policies provided formal guidance and  criteria for negotiating pollution prevention  conditions
 either as injunctive relief (i.e., the actual steps taken to correct the violation), or as supplemental
 conditions incidental to the correction of the  violation.

 Pollution prevention injunctive relief offers  the opportunity  for both the agency and firm to
 reduce  or eliminate an  environmental problem at the source,  without cross-media transfer of
 pollutants. Pollution prevention SEPs, and injunctive relief in some cases, offer the possibility
 of  reducing  environmental  impacts  in  excess  of that which is  required by  regulation.
 Furthermore, a prevention remedy or SEP may also reduce  impacts to media other than that
 which is targeted by the enforcement action,  if the technology is chosen or designed to deliver
 multi-media  environmental pay-offs.  Taken together, these benefits can enhance the firm's
 prospects for future environmental compliance.

 Significant "indirect" environmental, health, and economic benefits can be achieved through the
 transfer of pollution prevention technology to other  processes in the subject  plant or to other
plants owned by the firm; organizational changes that lead to improved environmental practices;
 and further implementation of other pollution prevention technology. Furthermore, particularly
 in the case of SEPs (where penalty relief is granted), the option to include a pollution prevention
project  creates an opportunity to turn a  negative situation into a better or positive  situation for
the firm and  to improve the relationship between the firm and the agency.

By including pollution prevention in enforcement settlements,  the agency can translate its stated
preference for pollution prevention into action—within the context of enforcement.   Pollution
prevention knowledge and skill-gained  by agency negotiators-can help to build the agency's
overall base of prevention expertise which can be leveraged in standard setting, permitting, and
inspection activities as well as in industry outreach programs.

Enforcement activities can serve as a vehicle by  which the agency encourages or partially
underwrites technological risk-taking in pursuit of innovative pollution prevention solutions to
challenging environmental problems.  This strategy can be targeted toward certain industries,
technologies, or high-risk chemicals (e.g., 33/50 chemicals) that have been assigned top priority
for risk reduction,  and/or where no or few cleaner technological alternatives are available.
Although the enforcement setting, with its adversarial backdrop and somewhat rigid legalistic
framework, is a challenging setting within which to facilitate innovation, evidence from the cases
demonstrates that the enforcement context has two distinct advantages.  First, firms can be
motivated to innovate, i.e., to overcome the barriers  to pollution prevention innovation that often
exist hi firms, through penalty reduction,  improved relations with the agency, and unproved
public relations (via publicity through press releases).  Second, since the firm has committed to
implement  the innovative project in its consent agreement with the agency (or to pay stipulated
penalties),  there is a strong incentive to stick with  the project even when technical difficulties
arise. Enforcement thus creates a "window of opportunity" in which options for technological
change receive more serious consideration than usual.

The option to promote pollution prevention within the enforcement context permits the agency
to pursue a settlement that optimizes environmental performance, rather than a settlement aimed
only at achieving compliance.
Other Reports and Guidance on Pollution Prevention in Enforcement

At least three  other  studies have been  conducted on the agency's experience in including
pollution prevention in enforcement.  They are:  "Investigation of Environmentally Beneficial
Expenditures for Settlement Agreements," by IT Environmental Programs, Inc.  for U.S. EPA
Off ice of Compliance Monitoring, Toxics Enforcement Branch, May 1992; "Pollution Prevention
Through Compliance and Enforcement:  A Review of OPTS Accomplishments",  U.S. EPA
Office  of Compliance  Monitoring,  January 1992;  and  "Innovations  in  Compliance and
Enforcement:  Supplemental Environmental Projects in EPA's Toxics and Pesticides Program",
U.S. EPA Office of Compliance Monitoring, Office of Prevention,  Pesticides,  and Toxic
Substances, November  1992.   Our study has  benefitted greatly  from, and builds on, this
previous work.

In addition, we refer the reader to a November 1993 memo from the Region I Administrator's
office that contains practical guidance on negotiating SEPs.

       IV  RECOGNIZING AND CREATING THE POTENTIAL FOR POLLUTION
     PREVENTION IN A FIRM:  TECHNICAL AND ORGANIZATIONAL FACTORS

 The success of the agency's efforts to include pollution prevention in an enforcement settlement
 is contingent upon the firm's willingness and capacity to change its production systems.  This
 section addresses both technical and organizational factors that affect the willingness and capacity
 of the firm, and ways in which agency negotiators can help to create conditions that are
 favorable to pollution prevention injunctive  relief and SEPs.
         The success of the agency's efforts to include pollution prevention in an
         enforcement settlement  is contingent upon the firm's -willingness  and
         capacity to change its production systems.
 A. TECHNICAL FACTORS

 1. Pollution Prevention Information. Knowledge and Expertise on the Part of the Firm

 Firms come to the negotiation table  with vastly different levels of pollution prevention
 knowledge, expertise, and general technological sophistication.  Larger companies tend to have
 greater in-house technical, regulatory, and R&D resources and therefore are more likely than
 smaller companies to have prior knowledge of, and expertise in, pollution prevention.  With
 respect to SEPs, larger companies may have one or more pollution prevention projects "in the
 wings" at  the time of the violation, making the task  of proposing an SEP to the agency
 negotiators somewhat simpler. For companies with little or no prior knowledge and experience
 in pollution prevention (typically smaller firms), the pollution prevention SEP process presents
 many  challenges,  including:   learning  the
 pollution prevention  concept and how  the
 techniques can be integrated into their existing
 manufacturing processes, developing an SEP
 proposal that is acceptable to the regional
 negotiators, and instilling confidence in the
 agency that  they  are able  to  execute  the
 project.

 The  process  of  encouraging  a  pollution
prevention  outcome within the firm could be
facilitated by the involving so-called "change
agents" and  "technical gate-keepers" within
the firm in the negotiation process.  A change
agent may be  a  technical or non-technical
person that  sees,  and can  champion,  the
Technical Factors

•  Pollution prevention information,
knowledge and expertise on the part of
the firm

•  Consultants

•  Potential to transfer technology within
the company

•  Potential for innovation
                                         V-l

-------
benefits of pollution prevention within the firm.  A technical gate-keeper is an individual that
effectively brings into the firm, and disseminates within the firm,  the technical information
needed [to change technology or] to fuel the research and development processes that are key
to the creation and implementation of new technical ideas.15  Production line staff are often the
source of important information on the sources of waste and ideas  on how to reduce it; and
union representatives are becoming increasingly aware of the sources of,  and remedies for,
environmental problems in industrial operations.

If the subject plant is one of several owned by the firm, other plants may be a source of ideas
or pollution prevention technologies that can be transferred to the subject facility.  Furthermore,
if the plant is a subsidiary  of a foreign corporation, the foreign owner may be a source of new
manufacturing technologies.

2.  The Role of the Consultant

Many firms,  particularly  smaller firms,  choose to rely on outside technical consultants to
supplement in-house technical capabilities. Outside consultants not only fill a need for additional
technical  expertise, as  we  heard in  several  company  interviews, they  also  help to build
confidence  for  the  SEP proposal in  the regional negotiators (whether the technical ideas
originated from within the firm or the consultant).  Therefore, some firms may face a barrier
to SEP inclusion if they do not use a technical  consultant.                             ,

The choice of consultant will, in part, determine the type of project proposed. If the company
hires a  consultant to assist  in correcting a violation, it is  likely that the  consultant will be
retained to develop a pollution prevention SEP proposal.16 Few environmental consulting firms,
i.e., those firms that have traditionally focused on compliance audits, design and implementation
of pollution control systems, and other regulatory services, have experience in assisting firms
to implement pollution prevention.                                              ,      -:

With respect  to injunctive relief,  many environmental consulting firms have strong incentives
to recommend capital intensive pollution control projects to solve environmental problems, since
these firms derive a large share of their income from  pollution control system design  and
construction (not from recommending that firms redesign their production processes or to switch
to a new process chemical).17 In addition, these consulting firms (particularly the larger firms)
prefer to recommend and install the same pollution control system as often as possible since it
is cost effective to duplicate plans and specifications (e.g., recommending a cyanide chlorination
    15 See for example, "Chakrabarti, A.K. and Hauschildt, J., The Division of Labour in Innovation Management."

Cambridge, Mass.: MIT Press, 1977.

    16 See Metal Filing Furniture Manufacturing (MFFM) and Casted Metal Products Manufacturer (CMPM) cases.

    17 See the Casted Metal Products Manufacturer (CMPM) case.                 ..,

-------
  system  rather  than cyanide  elimination).18  Consulting  departments/divisions of  equipment
  vendors have great incentive to sell their equipment or chemicals and will tend to solve problems
  accordingly (see for example, the Metal Machining Company (MC) case).19 20

  Increasingly,  environmental  consulting  firms  are  upgrading  their  services  to  include
  recommendations and design services for "off-the-shelf" waste minimization techniques; though
  the tailor-made changes that would be optimal for a given production situation are unlikely to
  be suggested from sources outside the firm.  These changes  are  generally  too risky  for  the
  average environmental  consultant to recommend and undertake.

 3. Potential to Transfer Technology Within the Company

 Firms with more than one production line and/or plant often test a  new technology on a single
 line an'd, if successful,  transfer the technology to  their other lines or plants.21  This strategy
 offers great potential to multiply the impact of a single pollution prevention project  where  the
 technical change implemented as an SEP or injunctive relief is made to one of several  similar
 processes operated by  the firm.  While there  is theoretical potential  to license  or sell new
 technologies to other firms, firms tend to regard their technologies  as proprietary-giving them
 competitive advantage.

 4. Potential for Innovation

 Section II C contains  an enumeration of several factors-internal and external to the  firm-that
 affect its willingness and capacity to innovate. While these factors do not, and cannot,  constitute
 hard-and-fast rules  to determine the  potential of a particular  firm to  innovate for pollution
 prevention,  they can serve to illuminate favorable conditions. From the narrative in  Section II
 C, the presence of the following factors may be indicative of a climate conducive to innovation:
     1ft
        Personal conversation with Daryl Beardsly, pollution prevention consultant, August 4, 1993.

        Alternatively, a firm that hires a consultant with pollution prevention expertise may constrain the
consultant's ability to propose certain projects either by giving them a fairly narrow compliance problem to solve,
requiring a quick-fix solution, a low-risk solution, or a "low maintenance" solution (e.g., a metals precipitation system
as opposed to a recommendation that the plant optimize their production process to reduce metals dragout which may
require operator education and training and may at times affect product quality), (personal conversation with Joseph
Conzano, Case Officer, EPA Region I.

        The small consulting firm, or the one or two-person operation, with pollution prevention knowledge and
experience (of which there are a few) are less likely to be encumbered by the issues raised in this paragraph.

    21   This was evident in several of the case  studies, notably Lid Manufacturer, Medical Device Manufacturer,
and Metal Machining Company.
                                             V-3

-------
      •      production units that are relatively small-scale and flexible, as opposed to large-
      scale, highly automated, mass production systems

      •      production units that produce a diverse and constantly changing array of products

      •      firms that have engineering and R&D departments               ......

      •      firms that have significant positive cash flow

      •      firms that are expanding, or are part of a growing industry

      •      firms that have a prospect of developing new  technology or products for the
      market, and marketing capacity to exploit these opportunities

      •      firms anticipating stringent future environmental and/or occupational safety and
      health regulation

      •      firms experiencing  public and/or market pressure to reduce the environmental
      and/or public health impacts of their processes or products

5. Fear of Technical Failure

When considering technology options for injunctive relief, the firm has great incentive to pick
a option that is perceived to have a low risk of failure  since, if the project fails to meet the
regulatory requirement, the firm  will incur:  additional cost  in developing and implementing
another technical option, additional legal and administrative  costs, as well as prolonging the
uncertainty associated with a pending enforcement case.  Therefore, where pollution control and
prevention options exist,  if a pollution control option appears  to have a lower risk of failure, it
will have greater appeal to the firm.

Fear of technical failure is also a consideration in the context of an SEP;  if the SEP fails, the
company may have to pay the mitigated portion of the penalty in addition to the administrative
costs associated with SEP progress reporting and the project  development and implementation
costs.
 B. ORGANIZATIONAL FACTORS

 1. Support from Top-Level Decisionmakers

 For pollution prevention SEPs to be included in negotiated settlements, firm owners, CEOs, or
 senior managers must be supportive of the SEP concept and must approve the use of resources-
 in-house staff  technical and legal consultants,  and other development  and implementation
 expenditures-to support the SEP process.  We found that a decision, by these actors, to pursue


                                           V-4

-------
  a pollution prevention SEP is typically based on some combination of a desire to mitigate the
  penalty and  recognition of the benefits  of the  pollution prevention project to the firm.   In
  competition with these two incentives is the desire to settle the case quickly to avoid a prolonged
  negotiation or "contractual relationship" with the agency (and the accompanying added legal and
  financial uncertainty) as well as the perceived risk of project failure.  Therefore, the desire to
  mitigate the  penalty plus the perceived value of the pollution prevention project will have to
  outweigh the desire for a quick settlement plus  perceived risk.
Organizational Factors

•  Support from top-level decisionmakers

•  The firm's legal counsel

•  Economic considerations
 With   regard   to   pollution   prevention
 injunctive relief, the preceding narrative on
 the firm's fear of technical failure is relevant
 here as well.

 Beyond conferring approval for the project,
 the commitment and involvement of top-level
 firm   decisionmakers  in  choosing   and
 implementing a  pollution prevention  course
 can improve the prospects of success  for the
 project  itself  (by   ensuring   a   steady
 commitment of resources and high priority status), facilitate top-level learning about the merits
 of pollution prevention, and promote organizational change toward a more environmentally
 responsible company.  Numerous business executives and studies have stressed the importance
 of top-level commitment to the success of corporate environmental initiatives.22

 2.  The Role of  the Firm's Legal Counsel

 Many of the case studies demonstrated the importance of the role of the firm's legal counsel in
 negotiating pollution  prevention  SEPs, specifically  with  regard  to  helping to  establish
 implementation schedules, milestones, and stipulated penalties. The cases suggest that attorneys
 with experience  in environmental  settlements, and, more  specifically, with  experience  in
 negotiating SEPs may facilitate the  inclusion of pollution prevention SEPs, particularly where
 the nature of the technological change or the firm requires complex settlement terms.

 3.  Economic Considerations

 Pollution prevention  investments often carry with them both "hard" economic benefits (e.g.,
 material, energy, water, and waste disposal cost reductions) and "softer" economic benefits
 (e.g.,  improved  future  compliance/liability position, improved rapport with agency, public
 image, etc.). So-called hard economic benefits are directly linked to investment choices and are
 quantifiable;  whereas  softer benefits  are less direct, difficult to trace and to quantify (e.g.,
    22  See, for example, Schmidheiny, S. with the Business Council for Sustainable Development," "Changing
Course:  A Global Business Perspective on Development and the Environment." Cambridge:  MIT Press, 1992.
                                           V-5

-------
longer-term benefits such as avoided future liability).  Firms are motivated by both types of
economic factors in making investment decisions, to different degrees and in different fashions.
For example, harder costs are typically quantified and included in the calculation of profitability
indicators  (e.g.,  payback  and  return-on-investment  (ROI));  softer costs  are  considered
qualitatively and not  included in profitability calculations.   For  smaller firms, with shorter
planning horizons, hard cost factors tend to drive investment decisions.23

With respect to SEPs, where the capital cost of the project is high, the financial payback of the
project is low, and the penalty reduction is relatively small (as  a percentage of capital cost), the
firm  may see  little financial incentive to implement a pollution prevention SEP or may have
difficulty raising the necessary capital (particularly hi the case of small firms).  In these cases,
it is especially important that the firm be cognizant of the indirect [softer] economic and other
benefits that can accrue from undertaking pollution prevention.   These benefits may  well be
more significant than the more direct economic savings.24              ,
     23  For further reading on the subject of financial analysis of pollution prevention investments, see:  White,
 A., Becker,  M. and Goldstein, J.  "Total Cost Assessment:  Accelerating Industrial Pollution Prevention through
 innovative Project Financial Analysis, with Applications to the Pulp and Paper Industry."  A report to the U.S.
 Environmental Protection Agency, Office of Pollution Prevention and Toxics.  May 1992.

     24  None of the case study firms faced these barrier as such; however, several EPA case officers and attorneys
 interviewed  stated that their inability to reduce the economic benefit portion of the penalty has  constrained their
 ability to leverage pollution prevention SEPs. The full report suggested that agency negotiators should be less
 generous with penalty mitigation when economic benefits of the project are direct and quantifiable, and more
 generous where benefits are indirect and difficult to estimate.

-------
  V  ELEMENTS  OF A SUCCESSFUL NEGOTIATION PROCESS AND SETTLEMENT

This section covers a number of elements that emerged from the case studies  (and other
research)  as important determinants of success, both in realizing  opportunities for pollution
prevention hi SEP  and  injunctive relief negotiations, as well as in crafting the terms of the
settlement. The elements are organized into three sections: elements relevant for both pollution
prevention injunctive relief and SEPs; elements particularly relevant to SEPs; and finally,
elements particularly relevant to injunctive relief.
A.  ELEMENTS RELEVANT TO BOTH INJUNCTIVE RELIEF AND SEPS

1.  Structuring the Negotiation Process

The negotiation process itself should be specifically designed to encourage and accommodate
pollution prevention SEPs and injunctive relief in the context of the particular situation facing
the parties, rather than letting an ad hoc process evolve. For example, when violators have little
or no familiarity or experience with pollution prevention, pollution prevention audits should be
encouraged  and the cost  of these audits should be considered  in the determination  of the
appropriate level of penalty mitigation (particularly for smaller  firms).

For both the agency and the company, the
different roles of the technical  and legal
participants must be carefully delineated.
It may be difficult to have a constructive
technical   discussion   in  a   charged
atmosphere characteristic of the adversary
process.   Preparing  ahead  of  time and
charting the evolving  roles of the various
players    would   be   worthwhile.
Furthermore, because the interactions of
the parties will  continue  over a year or
more, continuity of personnel assigned to
a  particular  negotiated  settlement  is
important.
 Elements Relevant to Both Injunctive Relief
                and SEPs

•  The negotiation process design and
structure

•  Information

•  Tuning and time allowed for pollution
prevention responses

•  Project monitoring
Where  innovation rather than  diffusion-driven technological  solutions  offer  the greatest
environmental  benefit,  if necessary,  the  pollution prevention agreement should  contain
appropriately flexible terms and conditions to permit some  experimentation and technology
development.  The Medical Device Manufacturer (MDM) settlement contained such terms.  In
this case project milestones and stipulated penalties where structured to allow the firm to test and
develop the deionized water degreasing system before committing to purchase the equipment.
These types of settlements should be reserved for those firms that have demonstrated good faith
                                         VI-1

-------
and could  be encouraged  where  the new technology  addresses  a  particularly problematic
environmental problem and/or where few  "cleaner" technology alternatives currently exist.

2. Provision of Information

It is important that the  agency give pollution prevention/enforcement policy and SEP policy
information to the company early on in  the process and to stress that  pollution  prevention
responses are at the top of the EPA hierarchy.  Policy information can be delivered,  as done by
several attorneys, by giving the violator copies of the actual agency policies.

The agency negotiators can also serve a useful role in steering those firms with little pollution
prevention knowledge and  expertise to sources  of technical information.  Furthermore, where
the firm is seeking  a technical consultant, the agency can suggest  that the firm  look for  a
consultant  that has a proven record in facilitating pollution prevention for their client firms.

Ideally, industry should be provided with a handbook on pollution prevention in general, relevant
portions  of the agency's enforcement policy,  sources of technical information and suggested
guidelines  for choosing a technical consultant.

3.  Timing and Time Allowed for Pollution Prevention Responses

The timing of the agency's recommendation that the violator pursue pollution prevention for
compliance or the  timing  of the  agency's "offering"  of  an SEP  option  may be particularly
important.  The suggestion or offer should occur early enough in the agency-company dialogue
to receive serious consideration  by the firm  and not too far along such that the interaction
becomes too adversarial.  The firm should be granted adequate time for proposal development
and implementation.

4.  Project Monitoring

Adequate monitoring of project progress is essential for a variety of purposes: to keep sufficient
pressure on company to pursue and complete the project,  to ensure continuing agency interest
and support,  and to promote both agency and firm learning in the implementation process.
Settlements with pollution prevention conditions generally have more milestones than the usual
settlements. Regions are beginning to implement Local Area Network-based  computer tracking
systems (e.g., Region 1) to follow compliance milestones-these systems can ease somewhat the
additional monitoring burden associated with increased monitoring requirements.

 5. Multi-media Approaches and Multi-Media  Pav-offs                           ,

 The adoption of pollution prevention technologies with multi-media pay-offs will be facilitated
 by a  shift, wherever possible, from  single-medium enforcement strategies  to a multimedia
 approach.'  Through multi-media inspection, the firm may  listen with a  "number of ears" and
 be prompted to think of more comprehensive solutions to their pollution problems. Multi-media

                                           VI-2

-------
 inspection and enforcement can provide an opportunity for  single-medium technical  experts
 within the agency to pool their pollution prevention know-how to create multi-media pollution
 prevention expertise within the agency.25 Particularly in the context of injunctive relief, where
 a  multi-media pollution prevention  response can be  identified, the  firm may  be more
 economically attracted to this option-than to a single-medium pollution prevention project or
 pollution  control-because  a  single  production  change  may  solve  several  problems
 simultaneously.
 B.  ELEMENTS PARTICULAR TO SEPs

 !•  The Need for, and Use of. Pollution Prevention Knowledge and Expertise

 There are five major activities within the pollution prevention SEP process where a case officer's
 knowledge of, and expertise in, pollution prevention can be an asset.  The five activities are:
        1.
        2.
        3.
        4.
        5.
encouraging the firm to propose a pollution prevention SEP;
facilitating the development of an SEP proposal;
evaluating the SEP proposal;
monitoring the implementation phase; and
evaluating the success of the SEP.
 Three types of pollution prevention knowledge and expertise seem to be important for supporting
 and enhancing these five activities: (1) a clear general understanding of the concept and benefits
 of pollution prevention, (2) a case officer's ability to ask exploratory questions that generate
 "pollution prevention'thinking" on the part of the firm, and (3) a  case officer's knowledge of
 pollution prevention techniques.
           Elements Particular to SEPs

           •  Pollution prevention knowledge and expertise:

              - a clear understanding of the concept and benefits of pollution
              prevention

              - a case officer's ability to ask exploratory questions that generate
              "pollution prevention thinking" on the part of the firm

              - a case officer's knowledge of pollution prevention techniques

           •  Technically difficult or risky  projects

           •  Adequate incentives to firms  without  "giving away the store"
                                           VI-3
    25
       EPA's "Multi-Media Screening Inspection Program Guidance 'and National Checklist" (May 1993) is a
useful tool for planning, coordinating and conducting multi-media inspections.

-------
In order to encourage  a firm to propose a pollution prevention SEP, arid to elicit a suitable
project proposal, it is important for the case officer and attorney to clearly convey the concept
and benefits of pollution prevention as well as the oft-mentioned list of pollution prevention
strategies—process  modifications, reformulation or redesign of products, substitution of raw
materials, good housekeeping practices,  etc..                                     ,

Beyond a general understanding  of the pollution prevention concept and general prevention
strategies,  the case officer may be  able  to stimulate and direct a firm's  "pollution prevention
thinking" when the firm is beginning to consider a SEP proposal.  Using even a limited amount
of information on the firm's technology-gathered during the inspection26 or during subsequent
discussions—a case officer can ask open-ended questions which may prompt the firm to recognize
pollution prevention opportunities.  Examples of open-ended questions are as follows:  "why are
you using'a solvent in mis process?" and "do you know the source of this contarninant?" Broad
familiarity and experience with pollution prevention approaches is necessary to effectively Use
this approach, though this  tact does not require specific expertise in the subject technology.27
In cases where the firm is unwilling to engage region negotiators in a discussion  about their
manufacturing processes (possibly  fearing further incrimination), this approach  may not be
feasible.

Knowledge of specific  pollution prevention techniques can be an  asset in negotiating pollution
prevention  SEPs or, more  likely,  in fully  exploiting the "pollution prevention potential"
associated  with a particular  settlement.   For this  discussion,  the  definition of "pollution
prevention  techniques" is important.   Used here,   the  term includes  both "general" ;arid*
"particularized"  pollution prevention  techniques.  General techniques can be thought of as
universal pollution prevention techniques that apply to many industries; examples are: switching
from organic solvent to aqueous-based cleaners, solvent distillation systems,  and closed-loop
cooling. The term particularized refers to those techniques that apply to a given manufacturing
process; examples are:  replacing solvent-based coatings with powder coatings in the coatings
industry and switching from hexavalent to trivalent chromium in metal finishing.   General and
particularized knowledge are important for all five activities listed above.  At minimum, case
officers  should be able to determine whether the project is  environmentally beneficial  and
whether there is unreasonable risk of failure (i.e.,  whether or  not the project is on  sound
technical footing). Ideally, the case officer should be able to provide guidance; general ideas
(if the company is open and receptive), constructive feedback on project shortcomings;  and
suggestions for project improvements during  the SEP proposal  development, evaluation and
implementation stages  (i.e., activities 2, 3, and 4 above).  The post-implementation evaluation
    26 The case officer can increase his or her knowledge of the facility (and potentially opportunities for pollution
prevention) by conducting the inspection with pollution prevention as well as regulatory compliance in mind. This
strategy was used by the case officer in the CMPM case.

-------
(activity 5) may require less technical expertise but can provide an excellent opportunity for case
officers to learn about pollution prevention, and to critically evaluate the technological changes
made and  their associated environmental benefits.

The case studies revealed that some firms  are already well versed in pollution prevention, are
technologically sophisticated/have retained a skillful pollution prevention technical consultant,
and have a good "ready-waiting" pollution prevention project. Several of the more innovative
or technically complex pollution prevention SEPs,  and the sole injunctive relief project in the
case study sample, were negotiated by case  officers with  little or no prior knowledge  or
experience in  pollution  prevention.28 . The companies  involved in these cases were quite
technologically sophisticated and/or had good technical consultants. In these cases, the technical
challenge for the case officer was to apply good engineering judgement to determine whether
the project seemed technically feasible and implementable within a given time period. However,
there may have been missed, better opportunities stemming from the case officers' lack of
pollution prevention expertise.   Unfortunately, this type of missed opportunity is difficult to
uncover in retrospective  case study research.

Pollution prevention technical expertise-either general or particularized~is gained primarily "by
doing", by verbal information sharing/pooling among technical colleagues,29 and can probably
be supplemented by effective training.  As more and more case officers have the opportunity to
negotiate pollution prevention into enforcement settlements, the expertise base will grow. This
process could be supported by encouraging and providing opportunities—formally and informally-
-for case officers to share knowledge and experience.

2. technically difficult or risky projects

Technically difficult pollution prevention projects,  projects that require R&D, and innovative
projects may require relatively long implementation periods, require fairly complex settlement
terms (e.g.,  a  complex schedule of stipulated penalties where R&D is required),  and carry a
higher risk of failure.   However, these projects may generate environmental benefits  in excess
of low risk,  diffusion-based pollution prevention projects at  the subject plant. These projects
may require  longer implementation periods,30 "creative" or somewhat flexible settlement terms,
    28  Industrial Coater, Metal Finishing Company, Medical Device Manufacturer and Bleached Kraft Pulp
Manufacturer.

    29  According to one EPCRA case officer actively involved in pollution prevention SEPs, the group works
effectively as a team, discussing projects and pooling their technical resources. This group is relatively small and
this facilitates information sharing.
    30
       Implementation periods over a year are generally considered long.
                                           VI-5

-------
 and risk-taking and risk-sharing.31

 Clearly,  not all technically difficult projects should be accepted as SEPs.  There are many
 concerns that need to be considered in a SEP decisionmaking process (e.g., if the company has
 not sufficiently demonstrated technical feasibility (i.e., is going on a "fishing expedition"), or
 if the time needed for implementation is so long  that it creates a  risk of either company
 personnel or EPA personnel changing). (The latter concern was cited by several case officers
 and attorneys as a reason why they prefer not to extend the implementation schedule beyond one
 year.)

 3-  Providing Adequate Incentives to Firms Without  "Giving Away the Store"

 Even though the agency should ensure that the penalty mitigation conferred does not exceed the
 direct economic benefits to the firm, the  agency should exploit and leverage the substantial
 indirect economic and other benefits that accrue to firms undertaking a significant technological
 transformation.  Firms are motivated by hard economic factors (e.g., material, energy, water, and
 waste  disposal  cost  reductions)   and   soft   economic  factors   (e.g.,  improved   future
 compliance/liability position,  improved rapport with agency,  public  image,  etc.).   Where
 economic benefits are direct, traceable, and quantifiable, agency negotiators should not, and tend
 not to, confer significant credit in penalty reduction.   Where benefits are indirect, difficult to
 trace,  and  to quantify (e.g., longer-term  benefits such as avoided future liability), agency
 negotiators should be willing to accord these benefits to the firm through penalty mitigation.

 Providing penalty mitigation for a pollution prevention project can be used to  "reward" those.
 firms that have a history of compliance, employ good environmental practices, have shown good
 faith in coming into compliance and in settlement negotiations, and in cases where the violation
 or its impact are not egregious (e.g., failure to submit a Form R under EPCRA).
C.  ELEMENTS PARTICULAR TO INJUNCTIVE RELIEF

1.  Achieving Compliance

Unlike SEPs, the question  of whether  pollution  prevention is included in  a settlement as
    31  "Risk-taking" in this context implies a strategy where the agency would agree to a pollution prevention SEP
that involves a higher than average level of technical uncertainty if the short and long-term potential benefit
associated with the project is great.  "Risk-sharing" implies that the agency is sharing the risk (and very likely the
cost) of developing and implementing a technically difficult/potentially high payoff project with the firm.  In Section
VII we suggest that this  strategy requires the agency to take a "portfolio approach" to pollution prevention SEPs by
allowing or expecting some technical failures, thereby encouraging some risk-taking as described here. Since
pollution prevention SEPs are, by  definition, supplemental and not designed to bring the company into compliance,'
there is less  environmental and political risk associated with a SEP that fails as a result of technical reasons as
compared to pollution prevention-based injunction relief.  Therefore, within reasonable bounds, SEPs may be an ideal
context for risk-sharing where a firm is a willing participant and has shown good faith.

                                            VI-6

-------
injunctive relief is typically a question of whether pollution prevention will be used instead of
pollution  control to bring the company back into compliance.   The stakes for the agency
negotiators tend to be higher in this context—as compared to the SEP context—because the agency
has a duty to the immediate and larger community to bring the violator into compliance and keep
it there.  (In the case of SEPs, the inclusion of pollution prevention represents an extra benefit,
albeit at the price of a reduced penalty.)  Therefore, where a firm is in violation of an emissions
limit and must effectuate a technology-based remedy (rather than, for example, a paperwork filing
response), the technological response must have a low risk of failure and must bring the plant into
compliance quickly.

To the degree that an effective, established, and familiar end-of-pipe technology will achieve this
objective, it will be an attractive choice.   If a pollution prevention alternative  appears to have a
higher risk of failure, or will take longer to  effectuate, it will be perceived as a less desirable
option. The Pollution Prevention in Enforcement Policy seeks to address this issue by "granting"
agency negotiators the flexibility to extend the average timeline for resolving the violation with
a pollution prevention remedy, if:  (a) the prevention  option will produce an  aggregate gain in
pollution reduction over the pollution control option, (b) the prevention technology is reliable and
available, (c) the prevention technology  is applicable to other facilities, and (d) the prevention
approach offers the best prospects for permanent return to compliance.  The agency negotiators
must make this determination.

2. Pollution Prevention Knowledge and Expertise

Where both pollution prevention and control remedies exist, the pollution prevention option will
be implemented only if the benefits associated with this choice are perceived to be superior, by
the firm and the agency, to the pollution control strategy.  Pollution prevention knowledge and
expertise within the agency are important to
encourage  and guide a  firm to consider
pollution prevention, as well as to evaluate
the merits of the firm's pollution prevention
injunctive relief proposal.
Elements Particular to Iniunctive Relief
•  The need to achieve compliance

•  Pollution prevention knowledge and
expertise:  advantages over pollution
control
                                           VI-7

-------
                                   VI CONCLUSION
The, benefits of negotiating pollution in enforcement agreements are realized directly through
changes in firm technology and associated environmental and human health benefits, as well as
through many tangible and highly valuable indirect environmental, health, and economic benefits
from:  the transfer of SEP technology to other processes in the subject plant or to other plants
owned by the firm;  organizational changes that can lead firms to view and address .pollution
sources in a more holistic fashion; further implementation of other pollution prevention projects;
and  changes in vendor/consultant relations  that will facilitate future adoption of preventative
rather than control strategies.  Furthermore, firms tend to see the  opportunity to implement
pollution prevention—either as an SEP or as injunctive relief—as a way to rum a negative situation
into  a better or positive situation for themselves, for their firm, and for their relationship with the
agency.

Enforcement settlements can be  structured to facilitate the adoption of innovative pollution
prevention technology,  and by doing  so, push the "technological frontier" to help overcome
challenging environmental problems.  Although the enforcement setting, with its adversarial
backdrop  and somewhat rigid  legalistic framework, is a challenging.setting  within which to,
facilitate  innovation, the  cases demonstrate  that the enforcement  context  has  two distinct
advantages. First, firms can be motivated to innovate, i.e., to overcome the barriers to pollution
prevention innovation that often exist in firms, through penalty reduction, improved relations with
the agency, and improved public relations (via publicity through press releases). Second-, since
the firm has committed to implement  the innovative project in its consent agreement with the
agency (or to pay stipulated penalties), there is a strong incentive  to stick with the project even
when technical difficulties  arise.  Enforcement thus creates a "window of opportunity" in which
options for technological change receive more serious consideration than usual.

                      QUESTIONS TO GUIDE NEGOTIATION OF
        POLLUTION PREVENTION IN SEP'S AND INJUNCTIVE RELIEF CASES
There are a number of technical and organizational factors that affect a firm's willingness and
capacity to adopt pollution prevention in an enforcement context.  To assist agency negotiators
in evaluating the potential for pollution prevention during the negotiation process, these factors
have been reformulated into a series of questions.  The questions are structured so that a positive
response indicates potential for pollution prevention.
Evaluating Technical Factors:

Q.  Is pollution prevention likely to decrease the firm's costs of pollution control, save material,
energy or water costs, or increase productivity?

Q.  Is the firm, its consultants, suppliers or other technical assistance providers familiar with the
concept and techniques of pollution prevention?

Q.  Are the firm's consultants likely to recommend or entertain pollution prevention projects, if
they are feasible and attractive?

Q.  Does the  firm  have one or  more appropriate pollution prevention projects that it had
considered prior to  violation?

Q.  Are  important   "technical  gate-keepers"  (including the  firm's  engineering  and  R&D
departments or consultants)  and/or potential "change-agents" participating in the negotiation?
If not, and they exist in the  firm, can they be brought in?

Q,  Is the subject plant one of several owned by the firm or foreign-owned? Can the plant obtain
information or technical assistance from other plants or its owner?

Q.  Is the pollution prevention project proposed likely to be transferred to other production lines
or to another plant owned by the firm?

Q.  Is the firm in a good cash flow position, a promising or growing market, or dependent  on
innovation to prosper?

Q.  Is the firm's technology  characterized by relatively small-scale and flexible production units
rather than large-scale, highly automated, mass-production systems?
                                          VII-2

-------
Evaluating Organizational Factors:

Q.  Are senior-level officers/managers of the firm supportive of pollution prevention approaches
and the opportunity to undertake the project in exchange  for penalty mitigation  or for other
strategic reasons?

Q.  Is the firm's  legal counsel experienced in environmental matters?  in negotiating SEPs?

Q.  Is the firm willing to take technical risks?

Q.  Are there indirect economic benefits (i.e., reducing current and/or future regulatory costs,
potential future liability), as well as direct economic benefits that are highly valued by the firm?

Q.  Is the firm concerned about their "environmental image"?
A set of organizational factors, concerning EPA regional offices, can enhance the ability of case
officers and attorneys to successfully negotiate pollution prevention conditions. These factors are
embodied in the next set of questions.

Evaluating Agency Factors:

Q.  Are the case officer and attorney sufficiently knowledgeable about pollution prevention and
negotiating pollution prevention settlements?             .'       .

Q.  Is the Regional Office philosophically supportive of these projects?

Q.  Are the case officer and the attorney in agreement on the necessary elements for approving
or encouraging a pollution prevention SEP or injunctive relief settlement?

Q.  Have the case officer and attorney agreed  upon their respective roles in encouraging such
settlements?

Q.  Is there potential for cooperation between the agency and the firm, i.e. is there a proper
atmosphere for negotiating pollution prevention agreements?

Q.  Is the agency willing to dedicate resources to monitoring and shepherding the project?

Q.  Has the idea of a pollution prevention project come up relatively early on in the
negotiation process?

Q.  Is the time allocated for the project to be completed realistic and acceptable to the
agency?

Q.  Is there appropriate "risk sharing"  between the agency and  the firm in case of technical
failure?

Q.  Has the agency provided reasonable incentives to the firm without "giving away the store"
or compromising the deterrence effect of inspection?

B.  A BRIEF TEXT DESCRIPTION OF INDIVIDUAL CASES

1.  Supplemental Environmental Projects

a.  Casted Metal Products Manufacturer (CMPM)

CMPM produces casted ferrous metal products using a variety of operations, including:  wax
pattern and sand/plaster mold production; mold dewaxing with heat; acid and caustic cleaning,
degreasing, bluing, phosphate coating, and tumbling of metal parts.  CMPM has approximately
1,200 employees and 3 buildings at the subject facility. The company owns two other plants; one
plant makes similar products, another produces only aluminum products.

The company was cited with two violations under the Clean Water Act: failure to file a Baseline
Monitoring Report (Section 403.12) and exceeding the chromium discharge limits and effluent
pH. The company was originally fined $95,000.  In consideration of their willingness to include
a SEP in their settlement, EPA reduced the fine to $30,000.

The SEP has two parts.  The first part consists of process and facility modifications to be made
by the company to reduce water and chemical use, and wastewater and hazardous  waste. The
second part  consists  of a Water Use and Wastewater Reduction Program designed  to identify
further measures to reduce water use and wastewater generation.

Part I requires the company to:

       A.    Reduce flow in its dewax cooling plates to reduce non-contact cooling water to the
             maximum extent safely possible.
       B.    Implement the following measures in the acid cleaning process:
             1.     Install a countercurrent rinse tank following the Hydrochloric Acid baths;
                    and
             2.     Route caustic rinse water as a reactive rinse to the countercurrent rinse
                    tank.
       C.    Implement the following measures in the acid cleaning area:
             1.     Eliminate the use of Nitric Acid;
             2.     Install countercurrent rinse tanks following the Sodium Hydroxide bath and
                    the caustic neutralizer baths;
             3.     Route  water from the countercurrent rinse tank  following the caustic
                    neutralizer bath to  the cold water rinse following the Hydrochloric Acid
                    bath; and
             4.     Route the water from the cold water rinse following the Hydrochloric Acid
                    bath to the countercurrent rinse following the Sodium Hydroxide bath.
       D.    Implement the following measures in the bluing area:
             1.     Install a two-stage  bluing bath on the electric bluing line;
             2.     Install flow control devices;
                                         A-8

-------
              3.      Investigate during summer shutdown, and if doing so will not negatively
                     impact product quality or manufacturing efficiency, route rinse water from
                     the cold water rinses following the bluing tanks in both lines .to the,cold
                     water rinses following the caustic cteane* baths; and.
              4.      Investigate during summer shutdown, and to the extent doing stj.will not
                     negatively impact product quality or manufacturing efficiency, reduce flow
                     in all process lines.
       E.     Implement the following measures in the phosphate coating area:
              1.      Replace caustic water rinse with  a dead rinse and a countercurrent rinse;
              2.      Use rinse water from the dead rinse as make-up water for caustic cleaner;
              3.%     Use a single cold water rinse following the phosphoric acid solution;,    7
              4.      Use a cold water rinse following the phosphoric acid solution bath as  a
                     reactive  rinse for the countercurrent rinse; and              .
              5.      Install a timer or conductivity flow controls to limit flow to after usage
            ,         necessary for product quality or manufacturing efficiency.,
       F.     Install flow control devices as appropriate in the tumbling area of Building C to
              reduce water use to the maximum extent possible without negatively impacting
              product quality  or manufacturing efficiency.
       G.     Eliminate the use of perchloroethylene, Freon, and  nitric acid in those processes
              discharging wastewater.                                     ;        ,    :,'
       H.     Reduce the  use of 1-1-1  trichloroethane  and isopropyl alcohol  to the  extent
              possible.

Part II includes implementation of a Water Use/Wastewater Reduction Program  designed to
reduce the Facility's water consumption  and wastewater generation to the  maximum  extent
practicable without negatively  impacting product quality or manufacturing efficiency as follows:

       A.     The company shall complete and provide to EPA a  Water Balance Survey of the
              Facility and a report describing all sources and amounts of intake water, all points
              of wastewater discharge, including evaporation, and  a description of the Facility's
              processes and activities that generate wastewater,  including contact  and non-
              contact cooling water. The report shall include a water balance schematic diagram
              illustrating the  above information, including daily volumes of water used and
              wastewater generated.

       B.     The company shall  complete and provide  to  EPA a  Water Use/Wastewater
              Reduction Study for  the Facility.  The Study shall  include plans and a schedule
              for, facility  and process modifications that the  company  will implement to
              minimize the Facility's water use and wastewater generation.

       C.     The company shall implement those plant and process modifications identified in
              the  Water Use/Wastewater Reduction Study to minimize  the Facility's water
              consumption and wastewater generation.
                                          A-9

-------
Through process modifications, the company has reduced wastewater discharges by approximately
100,000 gallons per day (approximately 75% reduction) and energy consumption by close-looping
water cooling processes. The SEP will leverage additional wastewater and energy reductions
since the company's ultimate goal is to close-loop the entire plant. The following table illustrates
chemical use reductions made by the company from the period of 1989 to May of 1991.

CMPM's Environmental Program Summary, June 1991.
While the changes made by the company are significant, they have not fundamentally changed
their core manufacturing processes, e.g., metal casting, acid and caustic cleaning, bluing, and
phosphate coating.

The average payback period of all SEP projects implemented  is 5 to 8 years.   While the
company's investment threshold is one year, they believe that the projects ware in their best
interest—economically and environmentally.  They have realized water savings of about 100,000
gallons per day and energy savings from close-looping water cooling processes.

The company was dissatisfied with their technical consultants~a geotechnical/environmental
engineering consulting firm.  In the course of the negotiations, the consultants recommended a
large and expensive treatment plant that the company ultimately realized was not needed. The
consultant contributed to  some degree with process change ideas—by reviewing and modifying
recommendations from the EPA case officer-but largely recommended traditional technical
problem-solving approaches.  The EPA attorneys, however, trusted the consultants and therefore,
the consultants helped to win agency approval for the technical changes that the company sought
to implement. The consultants were "educated" in the course of this process and they now use
the company as a reference for their pollution prevention work.  The company would not use
them again.
                                         A-10

-------
EPA compelled the company to implement water-use reduction measures far in advance and in
excess of what they would have done without the enforcement action.  In addition, the company
has implemented  some waste and water reduction measures in another plant.

Many of the technical ideas for the SEP came from the EPA case officer, who obtained insight
and project ideas from the shop floor, particularly from the line supervisors. Often, when the case
officer had a question about a process, he was invited to talk to the supervisors for explanations
and suggestions.

The  company  now  sees the connections between all of their emissions/waste compliance
obligations and source reduction activities; they have "tied it all together." They will not allow
any new chemicals into the plant without prior approval from the environmental engineer and
compliance officer.

Because the company did not initially have the capacity  (i.e., mode of inquiry and knowledge of
basic techniques), it was necessary for the EPA case officer to take a very technically involved
role in the process. Today, the company does not need  an external actor to play this role,  they
now have the in-house capacity to pursue further pollution prevention.  Prior to the complaint,
the company had  one person  in charge  of environmental compliance, and compliance was  only
one of his many responsibilities.  Today,  there are four people with environmental compliance
responsibilities-one full-time and three part-time.
b. Industrial Coater (1C)

Industrial Coater manufactures coated plastic film. In 1989,1C had projected sales of $20 million
and  employed  150-170  people. The company  is a  wholly-owned  subsidiary of a  foreign
corporation.  This parent  corporation operates a coating research and development facility at the
same site.  The research facility provides R&D support to Industrial Coater.

In August 1989, EPA issued a complaint against the company stating that they had failed to file
Form Rs for  toluene and  methyl ethyl ketone under EPCRA 313.

During the settlement process, the company proposed, and ultimately agreed to, implement a SEP
consisting of the reformulation of a toluene-based coating to a low or non-organic solvent-based
coating and alteration of the production process used to apply this coating to plastic film.  The
settlement requires the company to reduce by 90% the concentration of toluene (as compared to
dry chemical) in the coating and reduce by at least 50% the ratio of methyl ethyl ketone used in
cleaning  to production volume.

The current process of applying a coating to film involved the liquefaction, floating or dissolving
of a dry chemical in a solution with the solvent toluene. The new process will use a heat source
to melt the  dry chemical mix to a point where its liquefaction will be sufficient  for it to coat the
film without  the use of toluene. The project will include the installation of two banks  of high
                                         A-ll

-------
intensity infrared heat lamps to flow the coating prior to curing, and to stabilize and dry the
coating on the plastic web.   While solventless coating technology is not new in other industrial
applications, to the company's knowledge, this was the first attempt at solventless coating in this
niche of the coatings industry.

The company expects the new infrared heat lamps to dry the product more quickly thereby
allowing them to increase the speed of the coating machine. With increased speed, the company
can produce the same quantity of product during fewer production runs; fewer runs means fewer
clean-ups; 1C estimates that this changes will enable them to reduce its use of methyl ethyl ketone
in cleaning by an estimated 50% of current levels, from 4,600  to 2,300 pounds of MEK per
million feet of product.

The current solution of dry chemical and toluene applied  as a coating consists of approximately
70% toluene and 30% dry chemical. Approximate levels of use in 1991 were 24,000 pounds of
dry chemical  and 56,000 pounds of toluene.   The proposed change to the  process would,
assuming  a constant level of production, reduce the level of toluene used by 90%, to  5,600
pounds annually.  The amount of dry chemical used would remain the same.

The coating process currently uses an estimated total of 3.7 million Btus per hour, of which
approximately 525,000 Btus  come from burning solvent and the balance (3.2 million Btus) from
natural gas. Approximately 3,500 cubic feet per hour of natural gas are currently used in the
process. The process also uses approximately 9.7 kw per hour  of electricity.  The project is
expected to eliminate the use of natural gas and the burning of solvent in the coating process.
It will, however, require an increase of approximately 190 kw per hour of electricity to operate
the infrared heaters.  Because the project is expected to reduce gas and solvent energy use by the
equivalent of 1,080 kw per hour, the project is projected to reduce net energy use by 890 kw per
hour.

The total cost of the project was projected at $54,000, including $5,000 for development of the
new coating formulation done under contract by a consultant (Phase I), $25,200 for installation
and testing of new infrared lamps  (Phase II), $19,000 for  installation and testing of new coating
heating unit (Phase III).  The CA/FO stipulated that the company  shall expend not less than
$25,000 on the project.  In consideration of the SEP, the penalty was reduced from $50,000 to
$30,000.

The company estimated  the payback for this project to be 6  months  to 2 years, including
approximately $800 saved per day in energy conservation alone.

In developing their  SEP proposal, the company had assumed that they could use their existing
coating equipment to apply the new formulation. During pilot testing, they experienced problems
with this equipment and sought alternatives; as a result they were not able to switch to the new
formulation in time to meet the  SEP implementation deadline.  The company asked for  an
extension and EPA  granted one.   However, the company found it necessary to pay the penalty
and table  the  project because of seasonal,  high  production  demands, and the time and
                                         A-12

-------
administrative pressures created by the SEP process.  They are planning to re-initiate the project
in the near future since they consider it to be a "bonefide win-win situation" for the environment
and [their] enterprise.

The environmental benefits from this project derive from reductions in toluene and MEK use.
Based on the CA/FO Scope of Work, the quantity of MEK used would be reduced by 50%, or
2,300 pounds of MEK per million feet of product.  Since the CAFO did  not contain an annual
production figure, we are unable to estimate MEK reductions in pounds per year. Assuming a
constant level of production, toluene use would drop from 56,000 to 5,600 pounds annually—a
90% reduction.  The amount of dry chemical used would remain the same.

Fugitive toluene and  MEK air emissions are released into  the  plant and to the outdoor
environment in virgin and waste material handling and storage. Fugitive toluene emissions (i.e.,
emissions not captured by the  thermal  oxidizer) are also released from the coating process.
Toluene emissions from the coating operation may not be completely combusted in the thermal
oxidizer or may react under high temperature with other volatile materials  in the coating to form
toxic substances. These emissions are released into the environment.  Waste MEK solvent from
cleaning activities and waste coating containing toluene is sent to a hazardous waste incinerator.

By reducing the use of toluene and MEK, both fugitive and point source emissions from the
thermal oxidizer will be reduced.  A reduction in fugitive emissions inside the plant will reduce
exposure of workers to these solvents. The reduction of MEK and toluene waste will result in
reduced  hazards associated with transport of waste as well as reductions in emissions  from
hazardous waste incineration.

Recently, the company has used the services of the state technical assistance office and was very
pleased with their service and the fact that they are separate from the regulatory process. They
now use the state office for technical advice and a private consultant for compliance audits.
c.  Lid Manufacturer (LM)

The  subject plant is one  of several owned by a large manufacturing company.  The  plant
employees approximately  200 people in the production of metal lids with gaskets on four
production lines.

The company applied coatings containing VOCs in excess of limitations set forth in the federal
revisions to the State Implementation Plan under the Clean Air Act, Section 133d, and failed to
certify to EPA that its coating lines would either be exempt or in compliance with SIP emissions
limitations. The subject plant is located in a non-attainment area for VOCs.  The complaint was
issued in July  1992.

Prior to the implementation of the SEP, the company produced a gasket material by blending
rubber, heptane and other substances (the mixture is referred to as "compo"). Compo was coated
                                         A-13

-------
onto a metal lid and sent through curing ovens to drive off the heptane and form the gasket. The
heptane vapors were pulled into a recovery system. Since this system operated at approximately
76%  efficiency, almost  a quarter of the  heptane  emissions  (VOCs) were  released to the
environment.

The SEP consisted of the conversion of one of four production lines (constituting 1/3 of total lid
production) from the rubber and heptane-based gasket formulation to a new material containing:
PVC, BaSO4, dioctyl phthalate (DOP), soybean oil, CO2, and carbon black (the mixture is called
Plastisol).  DOP--20% of the new formulation—is an organic plasticizer and is not listed as a
toxic substance under the Clean Air Act Amendments of 1990. The formulation does not contain
VOCs other than soybean oil which has a negligible vapor pressure.

The conversion requires the modification of the gasket coating applicator and purchase of a new
curing'Oven. The company elected to equip the new process with a thermal oxidizer (afterburner)
to control air opacity if the Plastisol smokes in the drying oven.  It was not necessary to modify
its coating formulation process or change its operation of the gasket coating process.  The cost
of the SEP, according to  the company's October 1992 estimate was $298,000, and includes the
purchase price of the curing oven, thermal oxidzer (18% of the total cost), and lid curing trays;
in addition to oven installation, lid curing tray R&D, modifications to and relocation of the dryer
front.

The company estimated that heptane usage would decrease by 203 tons per year, resulting in a
reduction in VOC  emissions of 50  tons per year. They projected a potential emissions rate of
particulates from manufacturing, natural gas usage and oven emissions of 3.65 tons per year, and
less than 1 ton per year of each NOx, CO, HC and SO2 from the new process.

The original penalty of $123,947 was reduced to $76,000 for good faith and to $38,000 for the
SEP.

The company utilized a technical consultant who is a former employee of the state environmental
agency. Her knowledge of environmental regulations and the materials and techniques that satisfy
regulatory requirements was extremely beneficial to the company. Her main focus was technical
assistance for compliance, but she assisted in the design of the new system as well.

The company is working to ensure  that all of their plants are in  compliance with environmental
regulations.   It  held a compliance workshop  for representatives of each plant to stress the
importance of environmental compliance. LM has a corporate environmental manager and each
plant has an on-site person who is  responsible for plant environmental compliance.

The environmental benefit of the project is the elimination of 203 tons per year of heptane usage,
resulting in a reduction in VOC emissions of 50 tons per year.   The subject plant is located in
a non-attainment area for VOCs.
                                          A-14

-------
The  conversion may increase  the plant's particulate emissions by 3.65 tons per year from
manufacturing, natural gas usage and oven emissions, and less than 1 ton per year of each NOx,
GO,  HC.and SO2.

Plastisol contains PVC.  Thermal decomposition products of PVC have been shown to cause
"asthma"-like symptoms in workers who were heat sealing PVC films, although proper ventilation
and worker protection have tended to  minimize toxic effects.1  This may be a concern in the
subject facility since the Plastisol gaskets  are dried with heat.

Dioctyl phthalate (DOP) is one of a number of commonly used organic plasticizers which has
shown a low order of acute toxicity in laboratory animal trials2. In studies of teratogenic effects,
DOP and other esters  of  Phthalic Acid showed deleterious effects on the developing embryo
and/or fetus although  DOP was  considered one  of two of the least toxic esters of the eight
phthalate esters evaluated  in this study.3 Barium sulfate, an insoluble form of barium metal has
been found to be non-toxic owing to its inability  to absorbed by the body.4
d. Medical Device Manufacturer (MDM)

MDM is a medical device manufacturer that is highly regulated by the FDA.  In 1991, MDM
generated more than $50,000,000 in annual sales from several manufacturing facilities. Today,
through acquisition of several small companies, sales are considerably greater.  At the time of
violation, the subject plant employed approximately  100 people.

MDM failed to file Form Rs for xylene,  trichloroethane and trifluoroethane.  They agreed to
include a SEP in their settlement with the  agency and, as a result, the agency lowered their
penalty from $31,350 to .$24,000.

The medical device manufactured in the subject plant is degreased and sterilized using freon. At
the time of the agreement, the company used approximately 16,000 pounds of freon per year.
For their SEP, the company agreed to  engineer and test deionized water degreasing machinery
to determine if deionized  water can be used in place of freon.  If the testing demonstrated that
the new machinery is effective, the company will purchase, install and calibrate the machinery.
If the new machinery is not effective, the company will either stop manufacturing products that
require the use of freon, or pay an additional penalty.

-------
The deionized water system uses a two-step cleaning process.  First the product is washed with
deionized water and detergent; second, it is rinsed with deionized water in an ultrasonic bath.
The vendor has sold this system, with and without ultrasonic cleaners, for degreasing computer
chips in clean room environments.

The cost of the project  is  approximately  $80,000,  including  second-stage  testing, design
engineering and equipment purchase.  The project is not considered to be economically beneficial
to the company; it is favorably regarded by the Division Head for its environmental rather than
economic benefits.

The SEP stipulates that the company will incur no less than $10,000 for engineering and testing
of deionized water process machinery and not less than $65,000 to purchase, install and calibrate
machinery (unless they choose to discontinue production of products that use freon).

The company required  FDA approval prior to changing their  manufacturing  process.  This
requirement complicated the negotiation process—the company was able to test the new process
but had to submit the test data to the FDA prior to implementation and wait for FDA approval.
This additional step made  it difficult for the company and EPA to structure the agreement, and
particularly to develop the implementation schedule. The CA/FO had to be designed to give the
company an alternative to implementing the deionized water process in the event that:  (a) the
tests were unsuccessful, (b) their process change proposal was rejected by FDA, or (c) FDA
approval was  not received prior  to the SEP  deadline.  In addition, the time  line had to be
sufficiently long (16 months), and structured  in several steps, to allow for the FDA approval
process.

The company undertook the second stage evaluation, as outlined in the SEP, and considered the
new system to be a technical success.   However, for two reasons they have chosen not to
purchase the equipment and to pay the stipulated penalty. First, the subject facility is scheduled
to close in February of 1994. The company is moving its operations to another  plant.  Second,
the company is in a long and complex FDA product approval process and the submission of a
request to modify their process at this time could jeopardize the  entire approval.

MDM's engineering group has advanced the deionized project to a point where they have shown
that it can work well on their products.  The engineer that had worked on this project in the
subject plant will be transferred to the new site and will work to secure FDA approval for the
deionized system on that production line. This line will use a freon-based degreasing system until
FDA  makes a decision.

If the company had implemented the deionized water system in the subject plant, the SEP would
have accelerated the elimination of Freon in this facility.  The company, however, is planning
to pursue FDA approval for the  deionized system in their  new facility, based in part on the
research  and development conducted under the SEP.  The  SEP, therefore, may have had the
effect of accelerating Freon reduction in the  new  facility.  Additionally, the deionized water
equipment vendor may be  able to use the results of its evaluations on the company's product in
                                         A-16

 other applications and for other Companies.  To this extent, there  may be future technology
 transfer benefits associated with this project.       ,
e.  Metal Filing Manufacturer (MFFM)

MFFM employs 65 factory workers in the manufacture of steel  filing equipment and steel
shelving, using a  thermal setting paint resin on an automatic electrostatic paint line.   Paint
overspray is captured by filters and cardboard on the floor of the spray booths.  This waste and
straight paint waste are considered hazardous wastes. When these wastes are dried in a curing
oven they are no longer considered hazardous waste; just as the products painted and dried are
not considered hazardous waste.  Therefore, this company and many others like it sought to
reduce their hazardous waste disposal costs  by drying their  paint wastes.  Under RCRA,  this
activity is considered waste treatment and in October 1991, the company was cited for conducting
this activity without a waste treatment permit.

The company agreed to a SEP which required them to  investigate, and insofar as practicable
implement several identified process changes in an amount not less than $218,000. The company
committed to,  and ultimately implemented,  the  following:   installation of an on-site solvent
recycling system, installation of a baffle collection system for paint overspray in their electrostatic
sprayer, installation of improved paint collection systems in paint bays and electrostatic sprayer
to prevent overspray from collecting on floor, installation of paint drum agitators and pumps for
nonstandard color paint transfer, improvement of spray efficiency of the electrostatic sprayer and
hand held spray guns, and  continuous training of painters and operators in efficient painting
techniques.

As agreed to in the SEP, the company  instituted several administrative measures, including:
development of a pollution prevention policy, promotion  of plant engineer to vice president for
manufacturing  and environmental quality to carry out  the pollution prevention policy and
Program, training of all plant employees on pollution prevention strategies and opportunities for
waste reduction, attendance by management personnel at pollution prevention seminars for the
industry, development of an inventory control system,  improve the spray efficiency  of the
electrostatic sprayer and hand held spray gun, and continuous training of painters and operators
in efficient painting techniques.

The original penalty  was reduced from  $360,000 to $330,000 as a result of a downward
recalculation of the willfulness/negligence component of the penalty, and to $93,130 for the SEP.

All capital projects implemented under the SEP were  completed in beginning of June 1993.  It
is too early to tell whether the projects are economically successful.  The President has not seen
any payoffs so far from these changes although he thinks they may payoff in the future.  He
thinks that they are reducing pollution to a small extent.

f. Metal Finishing Company (MFC)

MFC manufactures solid cast brass nuts and bolts and chrome plated tubular plumbing supplies.
In 1991, they employed approximately 80 people and sales were in the range of $18 million. The
company operates one nickel and chrome plating line.  They discharge directly, after treatment,
to a canal with low water flow.

Prior to the SEP, the company generated a variety of hazardous wastes:  metal hydroxide sludge
(F006) and spent alkaline solution (which were manifested as characteristically hazardous for
chromium and lead), and lead contaminated polishing waste and spent chromic acid.  The facility
is a treatment, storage and disposal facility (TSDF).

The company was found to be out of compliance with  several requirements under  RCRA,
including:  failure to properly close hazardous waste storage containers of oil  and alkaline
solutions from machine shop and chromic acid from plating area; failure to label hazardous waste
containers  of lead contaminated polishing dust, mixed oil and alkaline solutions,  and chromic
acid.

After the EPA inspection, the V.P. of Operations learned of EPA's SEP policy in a class that he
attended on environmental compliance and pollution prevention.  This class is sponsored in part
by the state's technical  assistance program.  He decided to propose a SEP to EPA that would
eliminate the activities that contributed to the company's violations.  The SEP proposed by the
company consists of significant modifications to the company's automatic plating line to reduce
the  generation  of lead contaminated polishing dust waste and to convert from hexavalent to
trivalent chromium plating solution. At the request of the EPA negotiators, the company agreed
to implement a second SEP which was a measure designed to collect lead containing polishing
dust waste more  effectively.

In  order to reduce the  generation of lead  contaminated  polishing  dust waste, the company
replaced the existing nickel tank with a longer tank. The longer tank, plus an increase in the part
cycle time, is designed to improve the surface finish of the part so that a larger percentage of
parts do not need polishing to achieve satisfactory chrome plating.   Prior to the SEP, the
company generated 77 pubic yards of polishing dust waste annually. The reduction in polishing
was designed to  reduce generation of polishing dust by 65 to 85%, and to  decrease the lead
content in the dust. The change was projected to increase the company's use of nickel by 130%,
from 5,500 to 12,650 pounds per year.

To reduce the generation of metal hydroxide sludge, the company proposed to convert the chrome
bath from hexavalent chromium to trivalent  chromium. The company generated 16,700 gallons
of F006 metal hydroxide sludge from its nickel and chromium plating operation prior to the SEP.
They  projected this  change to reduce the  proportion of solids in the waste stream (metal
hydroxide sludge) by 33% and reduce metal hydroxide sludge generation by 5,500 gallons per
year.
                                          A-18

-------
Prior to the SEP, the company generated approximately 330 gallons of chromic acid per year
during their annual clean up and disposal of the chrome plating tank--a source of one violation
alleged in the complaint.  The switch to trivalent chromium eliminates this activity and the
resultant wastestream.  In addition, the elimination of hexavalent chromium decreases their use
of sulfur  dioxide which is used to reduce hexavalent chromium in the waste water treatment
process.

The company estimated that the lengthening of the nickel tank and conversion to trichrome (i.e.,
the first SEP) would cost $167,149, take two to four weeks to implement, and would require the
company  to invest $70,000 in inventory to supply their customers while the conversion is under
way. The company was required to spend not less  than $165,000 (including capital, design and
engineering labor costs, and construction  labor) on these two components of the SEP, according
to the CA/FO. The actual cost, determined after implementation, was $244,110.  The estimated
cost for the second SEP (i.e., the dust collection system) was $5,400; the actual cost was $5,173.
The original penalty was set at $325,000, was revised to $150,900 as a result of documentation
and  affidavits provided by the company.  The final penalty was set at $23,300 in consideration
of the two SEPs.

The company projected a  net yearly positive  operating  cash flow of $4,000 in the first year of
full  operation.5  This includes a reduction in hazardous waste disposal costs of approximately
$29,000 per year and a reduction in chromic acid costs of $1,000 per year. Increased nickel and
utility costs (100%  increase due to increased cycle  time and size of nickel bath) were projected
at $38,000 and $2,000 per year, respectively.  By planning to reconfigure product holding racks,
the  company did not project a slow down in output or increased labor costs.

Finally, at the request EPA, the company  agreed to modify their polishing dust collection system
by  the  constructing a fixed sheet metal waste collection unit that,  when  closed, provides
secondary containment around fifty-five gallon storage drums. This system is intended to provide
additional protection to the environment which is beyond the requirements of existing law and
regulations. The company was required to spend not less than $5,000 on these modifications.

The SEP  promised a 65  to 85%  reduction in the generation of polishing dust waste.  The
company  has cut its waste by  83  -  85%.  By reducing  the generation of lead  contaminated
polishing  dust and  the lead content in the dust, the SEP  reduces worker lead exposure and
disposal of lead and nickel waste generation.  However, the  company accomplished this by
increasing its use of nickel and electricity and consequently their associated environmental and
resource utilization  impacts.

The  switch from hexavalent chromium to trivalent chromium, results in several environmental
and worker health and safety benefits. First, less chromium is used in trivalent chrome systems
5       This calculation included depreciation.  However, the agreement subsequently reached prohibited the
company from depreciating its capital costs for the SEP. When recalculated omitting depreciation, the net yearly
operating cash flow is reduced to -$10,000.

                                          A-19

-------
than in hexavalent systems (their trivalent chromium bath  is 1/30 as strong  as their former
hexavalent bath and is considered about 1/10 as toxic).  In addition, the trichrome process has
decreased their F006 metal hydroxide sludge generation by  about 2/3. This has the benefit of
reducing environmental, public and worker health and safety impacts all along the lifecycle of
the product: chromium extraction, processing, transportation, use in plating, and ultimate product
disposal.

Hexavalent chrome has been shown to cause adverse health effects in workers.  While hexavalent
is considered  more harmful, health effects from trichrome have not been well researched or
documented.  Trivalent baths have a higher pH than hexavalent and thus pose  less of an acute
hazard to workers when bath materials are handled.  In addition, trivalent chromium systems
produce less hazardous chromium hydroxide sludge waste, eliminate the need for annual cleanup
and  disposal of chromic  acid bath, and elimination of use of sulfur dioxide in wastewater
treatment.

The company thinks that the change to trivalent chromium is in their long term interest. They
believe that regulations  are getting tighter and that all companies will eventually be required to
eliminate hexavalent chromium from their process.  They feel that they have an advantage over
companies who have not yet made this change—trivalent technology may get more expensive and
they will have the experience of operating the system.  The company instituted three major
changes in its operating procedures as a result of the enforcement action and SEP.  First, they
set up a chemical laboratory to monitor and maintain proper plating bath chemistry.  Second,
the Vice President takes an "environmental compliance" tour of the facility every six weeks; the
President participates in every second tour.  Third, the company will not bring new chemicals
into the plant without:  a thorough review of the Material Safety Data Sheet (MSDS) for each,
consideration  of the type of waste  that will be created by  the  use of the material,  and
consideration of how the waste will have to be handled if the material is used. If the material
will  pose problems in waste management and/or disposal, the company will not purchase the
material.

While the company did not use the state technical assistance program prior to or during the SEP
process, they are working with them now and are satisfied with  their assistance.
g. Metal Machining Company (MMC)

MMC is a plant owned by a multinational corporation; the plant employs 1,000 people and
generates sales of about $200 million per year.  The company produces engineered pump
components from metal and ceramic materials using machining and lapping6 equipment.
       A process designed to accurately refine the surface of parts using abrasive, rotating plates.

                                          A-20

-------
 In April of 1990, a EPA issued a complaint stating that MMC failed to file Form R's in 1988
 for phosphoric acid; 1,1,1 trichloroethane; xylene; methyl ethyl ketone under EPCRA 313. In
 October 1991 the company signed a CA/FO agreeing to implement a SEP.  In consideration of
 the SEP and  good faith efforts, the original assessed penalty  was reduced from $76,000 to
 $11,400.                                ,

 Prior to the SEP, the company utilized 1,1,1 trichloroethane (abbreviated 1,1,1) solvent immersion
 cleaning units for the majority of both in-process and final cleaning operations. Cleaning is done
 for both functional and aesthetic reasons.   The SEP consists of several changes to a subset of
 the company's parts cleaning systems designed to reduce the amount of 1,1,1 used by 130,000
 pounds per year^  MMC agreed to spend no  less than $201,000, by September 30, 1991, to
 retrofit a 1,1,1 degreaser used on non-metal  lapped parts to reduce organic solvent use and
 emissions (estimated reduction  in use of 1,1,1  of 3,000 gallons per year); and purchase, install
 and test equipment to switch from organic solvent to semi-aqueous-based cleaning of ferrous and
 non-ferrous metal parts.

 The primary environmental benefit  of this project is  the reduction in the use, emission and
 disposal of 1,1,1 trichloroethane~an ozone depleting substance.  1,1,1 is also a central nervous
 system depressant7 and is therefore hazardous to workers. Since emissions within the plant will
 be reduced, the project will have a positive effect on worker health. Since 1,1,1  is slated for
 phase-out under the Montreal Protocol, this and many other companies have been working toward
 the elimination of this ubiquitous and effective cleaning solvent. The SEP  has accelerated the
 company's reduction and ultimate elimination of this substance.

 In addition, the company conducted extensive evaluations of aqueous and semi-aqueous cleaning
 systems at a time when there was relatively little field experience with this technology.  This
 project has  paid-off in several  ways:   in-plant 1,1,1  reductions; transfer  of knowledge  and
 experience  to  other parts of the plant, other plants, and repair shops owned by the company;
transfer of knowledge and experience to other companies invited to examine the equipment and
talk to plant technical  staff; and education of the manufacturers and vendors of cleaning systems
that plant personnel dealt with during the course of their cleaning system evaluations.,
       Tbid.
                                          A-21

-------
The company considers the return on investment (ROI) for the project to be good, particularly
given the rising cost of 1,1,18.  1,1,1 use in the plant has been reduced from 30,000 to 17,000
gallons per year.9

There are about 43 other MMC plants and maintenance shops. All of these plants are moving
to eliminate the use of 1,1,1, in part because of the work done at the subject plant.  Other plants
have contacted the subject plant's plant engineer for information on alternatives.  Some plants
have already eliminated  1,1,1.

The company has recently engaged the services of a consulting branch of a organic  solvent
manufacturer to help them convert their remaining 1,1,1-based cleaning  systems  over to non-
organic solvent systems.  They chose this company because they are a manufacturer of 1,1,1 and
other organic solvents used  for cleaning and they  specialize in cleaning operations.   The
manufacturing engineer  is not  satisfied  with  the consultants because they proposed a very
expensive new cleaning system and the engineer does not trust that they are providing complete
information. Therefore,  the company is conducting their own investigation of the systems that
the consultants have suggested as well as other alternatives.
//. Powder Metallurgy Manufacturing Company (PMMC)

PMMC uses brass, steel, stainless steel, and metal alloy powders to produce machine screw nuts,
steel structural and special parts, and steel fasteners. Powder  metallurgy technology produces
precision parts that require little or no secondary machining.   The company has 50 employees.
and sales of between $5-6 million per year. The company is a member of the Metal Powder
Industrial Federation—a federation of four trade associations.  There are about  140  similar
companies in this country.

In 1989, the company was cited with failure to file Form R's under EPCRA 313 for the reporting
year 1987, for copper, chromium, trichloroethylene, and ammonia.

Prior to the  SEP, production of a finished part typically  included the following  steps:   (1)
compaction of metal powder in a mold to create "green" parts, (2)  sintering of "green" parts in
electric  ovens in either a  disassociated ammonia (hydrogen-nitrogen) or  methanol/nitrogen
atmosphere to prevent oxidation and corrosion, (3) burnishing of sintered parts to remove excess
metal and provide a smooth finish, (4) brightening of brass parts with chromic acid, (5) drying,
(6) resin impregnation for corrosion prevention, (7) tapping (thread cutting) of brass parts using
1      1,1,1 trichloroethane is an ozone-depleter and is being phased-out under the Montreal Protocol. Phase-out
is scheduled to begin in 1994 and prices for this widely-used solvent have been escalating.

9      This converts to approximately 300,000 and 170,000 Ibs per year (based on a specific gravity of 1,1,1 of
1.3390), for a reduction of 130,000 Ibs per year of 1,1,1 trichloroethane.
                                           A-22

-------
 a water soluble cutting fluid or a heavy black sulfur oil cut with kerosene, (8) water washing to
 remove the tapping fluid, (9) vapor degreasing with trichloroethylene in a vapor degreaser.

 In their settlement with the agency, the company agreed to implement a SEP costing $78,300.
 The SEP consisted of five components:  an environmental audit ($4,350),  the implementation
 of a blended hydrogen/nitrogen sintering atmosphere system to eliminate the use and storage of
 anhydrous ammonia ($50,598),  decontamination and replacement of an existing 10,000 gallon
 anhydrous  ammonia storage  tank,  with a  1,000 gallon tank  ($2,400), elimination  of a
 trichlorethylene vapor degreaser by switching from an oil-based tapping fluid to a water-based
 alternative ($500),  and the implementation  of a closed loop cooling system for non-contact
 furnace water which will reduce the discharge of non-contact cooling water to the POTW and
 conserve water ($20,451).                       ,       ,.-.-

 By switching from ammonia to blended hydrogen/nitrogen gases, the company eliminated the use
 of 1.5 million pounds per year of ammonia and the threat of a catastrophic release of ammonia
 gas.  By eliminating the trichloroethylene vapor  degreaser, the plant cut approximately 26,860
 pounds per year of fugitive trichloroethylene air emissions. Trichloroethylene  is an  ozone
 depleting substance, targeted for phase-out under the Montreal Protocol. In addition, the company
 significantly reduced  its generation of waste oil  by switching to a water-based coolant.   The
 company generated 1,600 gal per year of waste oil prior to this change.            ,

 According to the company, the projects implemented under the SEP are expected to payback in
 the "long run"~5 to 7 years.

 While not included as part of the CA/FO, the company also eliminated their chromic acid-based
 brightening process.  This action eliminated the chromic acid treatment sludge generated in this
 process.  In addition, through a series of energy conservation projects, the company has cut its
 energy costs by $4,000 per month.

 In consideration of the SEP, the agency reduced  the company's fine  from $76,000 to $30,550.
 The company was required to implement all components of the SEP within a 360 day time line.

 The projects implemented under the SEP policy had been considered by various members of the
 company prior to the issuance of the complaint.  The SEP process  was  the impetus for their
 implementation.

 Through the process of implementing "environmental investments" under the SEP, the company
President  has "changed his thinking" about  "environmental investments."  He realized  that
environmental standards are going to get tighter  and decided that instead of trying- to keep up
with them, it is better to lead them. He decided to eliminate trichloroethylene, chromic acid and
ammonia. While it has not been easy, the company has been able to move away  from certain
hazardous operations and these changes have been  economically and environmentally sensible for
the  company.

The President believes that a vision of cultural change must come from the top. He is trying to
apply TIM principles to productivity, quality, environment and worker health and safety.
L  Pump Service and Sales Company (PSSC)

The subject facility is one of several owned by a large, diversified holding company.  The plant
markets, sells and services pumps manufactured by a sister plant. Pumps received for repair by
the plant must be decontaminated and degreased for service and testing.  As a result of PSSC's
failure to  file a Form R for Freon (under EPCRA 313), the company entered into a Consent
Agreement and Order with EPA on October 1991.

Prior to the Consent  Agreement, the  company was using freon for decontamination  and
degreasing.  The company had begun efforts to reduce Freon use in late 1988 with the purchase
of a soap  and water-based spray washer for some decontamination of its pumps.  In the their
settlement, the company agreed to reduce, by not less than 66%, its December  1990 Freon use
rate in connection with its pump repair processes both at the subject facility and at a second
facility owned by the company.

The SEP  consisted of two phases: the first phase consisted of the installation at the subject
facility of two semi-aqueous cleaning units, each of which includes an in-line paniculate filtration
system, and the conversion  of the facility's existing ultrasonic finishing system from a freon-
based system to  an agitation/filtration system utilizing a biodegradable cleaning  agent.  The
second phase consisted of the installation at a second facility, in a different state and EPA region,
two semi-aqueous cleaning units of the same type as described above.

The company estimated the cost for the  two plants to  be  $69,475, including  $56,475  for
equipment and $13,000  for installation.  The Original penalty was reduced from $17,000 to
$8,500.

The environmental benefits associated with the project is the elimination of the use of Freon 113,
an ozone  depleting chemical, at two plants—the subject facility and another facility in another
state and  EPA  region.. While the company  agreed to a 66% reduction in Freon, the project
resulted in the complete  elimination.

According to the Material Safety Data Sheets (MSDS), the cleaning agent contains:  1-T-Butoxy-
2-Propanol, Dipropylene Glycol 1 Monoethyl Ether, and  Monocyclic Terpene Hydrocarbons.
While animal studies conducted by NIOSH has found that certain glycol ethers10 are fetotoxicants,
such evidence has not been found for Dipropylene Glycol Monoethyl Ether.  Monocyclic terpene
10      Ethylene glycol monomethyl ether (EGME), ethylene glycol monoethyl ether (EGEE) and their acetates.
Based on evidence of fetotoxicity in animals, for these glycol ethers, OSHA has proposed a downward revision in
the TLV for certain glycol ethers from 100 to 0.1 ppm.
                                          A-24

hydrocarbons are a class of plant-based materials which many companies are turning to as an
alternative to chlorinated organic solvents.  Recent discoveries, however, have linked water
effluent containing terpenes with ecotoxicty.

Through the SEP, the company has completely eliminated their freon use.  The project had an
8  month payback period and the company estimates  that it has saved them between $300-
$400,000 over the past four years.
2.  Iniunctive Relief

a.  Bleached Kraft Pulp Mill (BKPM)

BKPM is a manufacturer of bleached kraft pulp from woodchips.

In July 1991, the Company entered into a Consent Decree with EPA and a citizen's group to
come into compliance with chronic toxicity limits under the Clean Water Act and to minimize
potential impacts of effluent on recreational users. The CA/FO required the Mill to study a range
of potential remedial measures (including fluent treatment systems and in-plant process changes)
and propose to EPA a measure(s) to bring the Mill into compliance with chronic toxicity limits
under the Clean Water Act. In addition, the mill was required to construct an outfall extension
pipe capable of ensuring that the surf zone will be essentially free of mill effluent.

The mill conducted a  variety of effluent treatabiliry studies, trials involving different levels of
chlorine dioxide  substitution and use of hydrogen peroxide, and five full-scale trials of totally
chlorine-free (TCP) bleaching.   The  mill assessed the environmental benefits (e.g., chronic
toxicity,  dioxin  levels and AOX11;  and effluent  color), pulp  quality,  and production  cost
differentials during each trial.  Based on information generated during treatability studies and
bleaching trials, chose to  propose the TCP pollution prevention project highlighted here. This
remedial measure, as well as the construction of an extended outfall pipe and a system for steam
stripping of condensate from digesters and black liquor recovery system12 was agreed upon, in
a second Consent Order (signed by company in September 1992), as the means by which the Mill
would come into compliance with the chronic toxicity limit established in the Clean Water Act
and improve surf zone water quality for recreational use.

The pollution prevention project consists of the total  elimination of chlorine in pulp bleaching.
The Mill will eliminate their use of both elemental chlorine and chlorine dioxide and substitute
other process steps.  In the new process, the pulp will be bleached with hydrogen peroxide and
oxygen, rather than chlorine and chlorine dioxide.  Anthraquinone will be added to the digester
       A measure of chlorinated organic compounds.

       Condensates contain toxic materials that, in part, end up in discharged effluents. Steam stripping removes
most of these materials for wastewater streams.
                                          A-25

-------
 to increase lignin removal.   The Mill's conversion to chlorine-free bleaching will also include
 the re-routing of bleach plant wastewater from the sewer to the oxygen delignification system and
 ultimately to the black liquor recovery cycle and incineration in the recovery boiler. As a result,
 the organic materials (BOD) in the bleach plant effluent will be removed from the wastewater
 stream and burned for energy in the recovery boiler.

 The conversion requires  the construction of new chemical storage tanks  and replacement of
 certain equipment such as pumps, chemical mixers, piping and possibly corrosion-resistant linings
 in retention towers (to handle different bleaching chemicals). The project must be completed in
 September 1995.  The cost  of the project is not available.

 From  the Mill's  standpoint, the  advantages of eliminating chlorine were  improvements in
 environmental quality, occupational health and safety, public health and "psychological comfort".
 This strategy results in maximum reductions in chlorinated organic compounds, color, odor, foam,
 and contact irritation for a wide array  of Mill constituencies: beach walkers, surfers, kayakers,
 and anglers.  During the first trial they realized that the Mill was a more hospitable place without
 the use  of chlorine and chlorine dioxide.   This translates  into worker health and safety
 improvements (e.g., eliminating the occasional acute hazard of inhalation of high concentrations
 of chlorine and chlorinated  byproducts) and  reduced  public health hazards associated with the
 elimination of chlorine  transport and storage.

 The Mill will benefit economically from TCP pulping through savings in such things as:  worker
 safety  training  and safety  equipment purchases (e.g.,  self-contained breathing  apparatus),
 expensive metals needed to provide resistance to the corrosive properties of  chlorine), expensive
 corrosion-resistant plastic, and  paint films (chlorine is inhospitable to paint).  During a recent
 two-week run, the Mill saw improvements in operating costs, but  it is still more expensive to
 product TCP pulp than  the normal chlorine bleached product.

 A key  factor in considering  chlorine elimination was market demand for TCP pulp. The mill is
 not able to achieve maximum pulp brightness, as seems to be required by  a large  share of the
 bleached kraft pulp market.  In  some U.S. markets, in  Germany, and in other parts of the world,
 TCP pulps are  in demand  because of the  environmental concerns associated with chlorine
 bleaching. The Mill has not fully developed a marketing strategy. They have located end-users
 for whom chlorine use or chlorine content in the final product is a concern.  They are promoting
the use of TCP pulp to  governmental and institutional purchasing agents.

As a result of this experience, the company has changed the way it approaches regulatory matters.
Although they have traditionally involved technical personnel early in the process, they will seek
to involve these personnel in initial discussions with Regulatory  Agencies and bring attorneys in
later on in the process.  In this way, the company believes that they can have more productive
discussions about the technical  aspects of the project and then negotiate a final agreement.

 C.  CASE COMMENTARY AND ANALYSIS

 1.  SEPs versus Iniunctive Relief

 Of our ten case studies of pollution prevention in enforcement, only one case involves pollution
 prevention as a means to come into compliance (i.e., injunctive relief).  The other nine cases
 involve SEPs.  The case study selection criteria were not inherently biased toward SEPs; rather
 we sought innovative, somewhat unique pollution prevention projects from among our sample
 population of both SEPs and injunctive relief cases. One case that we selected, Bleached Kraft
 Pulp  Manufacturer  (BKPM), was the  only injunctive  relief case reported that contained a
 pollution prevention compliance strategy. We selected it because the pollution prevention project-
 -elimination of chlorine in kraft pulp bleaching—was innovative and had great technology transfer
 potential.

 2.  Companies

 Since our selection of case studies  was made largely  on the basis  of the  nature of the
 technological change, the distribution of company type and size are an artifact and not criteria
 of,  our selection strategy. Our sample is dominated by metal products manufacturers (six out of
 ten  companies).   Considering   that many  processes   used by these manufacturers  are
 environmentally problematic (e.g., metal plating, painting, and degreasing), and that historically,
 a great deal of attention has  been focused on pollution prevention in these  industries, the
 dominance of these firms in  our sample is  not surprising.   The other  four case study firms
 represent a rather broad array of industries: plastics coating, medical device manufacturing, pump
 service and sales, and bleached kraft pulp production.

 With regard to size, three  case study  firms-MFFM,  MFC, and PMMC~are  single plant
 companies ranging from 50 to 80 employees.   Two case studies~IC and PSSC-involve small,
 autonomous divisions of larger holding companies. Four case studies-CMPM, LM, MDM, and
 MMC~involve small/medium-sized  plants (100 to 1,200  workers) that are owned-by  medium-
 sized, multiplant companies.  The injunctive relief case--BKPM~is a large manufacturing plant
 owned by a large corporation.

 3.  Nature of the Violation CRegulatory Program')

 Of  our ten case studies, five arose out of violations of Form R reporting requirements under
EPCRA, Section 313; two stem from CWA violations; one from a CAA violation; and  one from
RCRA.  The predominance of EPCRA cases in our study sample reflects the relatively large
number of pollution prevention SEPs in the larger sample population that were negotiated in
EPCRA 313 settlements.  There  are several  reasons why the majority of SEPs  have  arisen in
EPCRA cases. EPCRA violations occur in companies that are using or producing toxic chemicals
(so  called 313 chemicals). In recent years, pollution prevention efforts, within and outside the
agency have focused heavily on the elimination, reduction or  recycling of toxic substances (e.g.,
EPA'c 33/50 Program).   Thus,  EPCRA cases tend to be natural  candidates for  pollution
                                         A-27

-------
prevention SEPs.  This is particularly true for companies using chlorinated organic solvents that
are slated to be phased-out under the Montreal Protocol and amended U.S. Clean Air Act.
Spurred by the London Amendments (1990) to the Montreal Protocol, the amended U.S. Clean
Air Act established a phase-out of CFC-113 (also called Freon) and 1,1,1-trichloroethane (also
called TCA or 1,1,1) in the years 2000 and 2002, respectively. HCFCs will be banned between
2020 and 2040 or earlier as spelled-out in the London Amendments.  As these dates approach,
the costs of these materials are increasing and, as a result, the alternatives are becoming more
economically favorable. Numerous, relatively low-cost aqueous or semi-aqueous systems are now
widely available. A switch to these alternatives typically poses relatively low or no technological
risk to the firm13 and may save the firm considerable amounts of money.14  These features are
motivations for both the firm and the agency to negotiate SEPs into these cases.15

Finally, according to one regional attorney, since the penalty assessed for 313 violations constitute
"gravity" only,  and not "economic benefit" (because there  is no economic benefit to  be gained
by not filing a Form R), a large percentage of the penalty  can be used to leverage a  SEP.16

4. Original and Final  Penalties, Project Cost and Payback

Table A-2 summarizes the penalty information and pollution prevention project costs for the nine
SEP case studies.  Penalty reductions granted for SEPs range from $7,350 to $237,000. In seven
of nine cases,  the penalty reduction leveraged a significantly  greater pollution prevention
expenditure by the firm. One notable case is LM which expended $298,000 to reformulate their
lid gasket material for a penalty reduction of $38,000.   In one  case, MFC, the cost of the
pollution prevention project was 25% higher than the penalty reduction.
11      FDA-regulated firms, such as pharmaceutical and medical device manufacturers, are a notable exception.
In these cases, manufacturers must obtain FDA approval to switch from solvent to aqueous-based cleaners (FDA
regulates product and process). The approval process can take several years and can be very costly. Therefore, these
firms tend to choose solvent recycling strategies rather than chemical substitution since recycling does not generally
require FDA approval.

M      The SEP policy contains a limitation on projects that represent a "sound business practice", i.e., capital or
management improvements where the firm, rather than  the public, is likely to receive the substantial share of the
benefits.  However, this  limitation  can  be waived only for pollution  prevention projects having  significant
environmental benefit (SEP policy, page 9).

15 •     Region V Attorneys and Case Officers offered several other reasons for the preponderance of 313 SEPs.
The EPCRA 313 reporting requirement is relatively new (since 1988); it virtually "grew up" with the Agency's
initiative to  include SEPs and pollution prevention in enforcement agreements.  According to a Case Officer in the
Region's Pesticides and Toxic Substances Branch (housing the TSCA and EPCRA programs), company attorneys
and private law firms are as unfamiliar with 313  as they are with SEPs, and it is easier to couple SEPs with 313
settlements than with settlements arising out of other regulatory programs.

"      According to the SEP Policy, only the gravity  portion of the penalty can be mitigated by the SEP.

We obtained payback information from case study firms  during our interviews.  In one case,
MFC, we acquired a copy of the company's profitability analysis which they had submitted to
EPA  during their SEP negotiations. Our data are a mixture of numerical payback estimates and
qualitative impressions  of project profitability.  In some cases we were unable to gain this
information, either because it was too soon for the company to know (MFFM) or because they
considered this information to be somewhat sensitive (LM).

Project payback ranges  from a very profitable 8 months ($300-400,000 saved over a four year
period) to a less profitable 5-8 years. Projects that involve the reduction or elimination of ozone-
depleting chemicals seem to be  more profitable than others because the  cost of these  organic
solvents  is steadily increasing as the final  phase-ou;t date^ approaches.

It is important  to note that profitability analysis of pollution prevention investments is highly
subjective. In particular, companies tend to omit certain financial benefits of pollution prevention
projects,  such as avoided  liability  and regulatory costs,  because  these costs are  difficult to
estimate and are speculative. Therefore, caution should be exercised in drawing conclusions from
reported  payback data.

5. Environmental and Human Health Benefits

There are two categories of environmental benefits that arise from pollution prevention SEPs and
injunctive  relief projects.   The  first category constitutes  environmental benefits  directly
attributable to the SEP or injunctive relief project; these benefits are the subject of this section.
The secondary category consists of the indirect benefits from pollution prevention implemented
"beyond" the enforcement settlement which were leveraged by the SEP/injunctive relief either
through technology transfer within/outside of the firm, or through organizational change within
the firm.  While the former is easier to measure and evaluate, the latter may be significant and
should not be overlooked.  We  address indirect benefits in the section on technology transfer
below.

To evaluate environmental benefits of pollution prevention, used as a means to compliance, i.e.,
injunctive relief, we can analyse the absolute benefits of the project and the benefits relative to
the technology that the company might have implemented had they not  chosen a preventative
strategy. In the case of BKPM, the absolute benefits of eliminating chlorine are quite significant,
they include: the elimination of chlorinated organic compounds from wastewater; reductions in
wastewater color, odor, and foam; elimination of worker hazards associated with chlorine and
chlorine dioxide; and public health hazards associated with the elimination of chlorine transport
and storage.  In addition,  by eliminating chlorine, the mill can cycle bleach plant effluent into
their black liquor recovery  system to recover energy and pulping chemicals from  bleach plant
effluent and reduce BOD  in discharged effluent.

When considering how to meet  the wastewater toxicity limits in their  Consent Decree, BKPM
initially considered increasing chlorine dioxide and hydrogen peroxide substitution of elemental
chlorine—process changes that constitute preventative strategies for reducing chlorinated organic
compounds.  In addition, they considered conventional secondary wastewater treatment and non-
traditional  treatment  technologies (e.g.coagulation/precipitation, ultrafiltration, and catalyzed
ultraviolet  light treatment).  The mill's,chosen strategy appears far superior on environmental,
occupational/public health grounds to bom the alternative prevention strategies and the treatment
alternatives.  The TCP option will eliminate rather than simply reduce chlorinated organics in
effluent, will eliminate chlorine hazards to workers and the public rather than reducing them
under the other prevention options ~ or having no effect under the treatment strategies.
                           *
To evaluate the  environmental benefits of pollution prevention SEPs, we can also consider the
absolute benefits of the  project and  the benefits  relative  to a  hypothetical scenario of the
settlement  without a SEP. The environmental benefits of SEPs—summarized in Table  A-l and
in more detail in the full case studies—are presented again in summary form in Table A-3 for ease
of reference.
                                          A-30

-------
 The following is an characterization of the types of environmental benefits achieved,

              The implementation of  five of the nine SEPs have/will  result in significant
       reductions in use and emissions of ozone-depleting chlorinated organic solvents-Freon
       and 1,1,1 trichloroethane.  While the use of these solvents will be phased-out under the
       Montreal Protocol, and amended U.S. Clean Air Act, these  SEPs achieve an accelerated
       reduction of long-lived ozone-depleting substances.

              The use and emissions of seven of the list of 17 target chemicals  of EPA's
       Industrial Toxics Project were/will be reduced in the nine SEPs studied:  chromium -and
       compounds,  lead &  compounds, methyl ethyl ketone,  nickel and compounds, toluene,
       1,1,1-trichloroethane, trichloroethylene.

              Two  SEPs--IC and MFFM-will/have achieved reductions in non-chlorinated
       solvent use (including methyl ethyl ketone and toluene) that will, among other benefits,
       improve the quality of the  work environment.

              MFC switched from hexavalent to trivalent chromium, resulting in an improvement
       in conditions for workers as well as reduced chromium emissions to the environment.  By
       reducing the generation of polishing dust containing lead and nickel, MFC's SEP reduces
       worker lead exposure and environmental loading of lead and nickel.

       •       Through the reformulation of jar lid gaskets, LM has significantly reduced its VOC
       emissions in  a non-attainment area for VOCs.

While the  pollution prevention  projects implemented under  the nine SEPs studied result in
significant  environmental and human health benefits,  it is important to point but that in some
cases new  sources of exposure or  pollution are created by the new technology. For example,
aqueous  and semi-aqueous cleaning agents, used in several SEPs to replace organic solvents,
become  a  new wastestream either released in wastewater to  wastewater treatment  plants or
drummed and disposed of as hazardous waste. Aqueous cleaners are not typically hazardous but
may become contaminated with hazardous substances during cleaning.17 If this is the case, spent
cleaner must either be treated to  remove contaminants before discharge to the sewer or, like the
organic solvents they replaced, must be disposed of as hazardous waste. In these cases, it is the
contaminant (i.e., the material "cleaned-off the product) that is the  culprit, not  the aqueous
cleaner itself.

-------
While semi-aqueous cleaners are biodegradable, non-ozone depleting and often recyclable, they
may contain slightly hazardous constituents. For example, the cleaner adopted by PSSC contains
terpene, a plant-based hydrocarbon material which pose the risk of flashing at room temperature.
While EPA has not fully studied terpenes,  limited testing of a terpene called d-limonene by the
National Toxicology Program in 1990 has shown positive carcinogenicity in male rats.  The
strong odor of terpenes may be offensive to workers, requiring adequate ventilation.18 Like their
aqueous counterparts, semi-aqueous cleaners may be contaminated by hazardous materials during
cleaning.  For example, spent semi-aqueous cleaner used to de-contaminated pumps at Pump
Service and Sales Company (PSSC)  is disposed of as a hazardous waste.

In the case of LM,  reductions of VOC emissions came at the price of small increases in NOx,
CO, HC and SO2 emissions and MFC reduced the generation of lead contaminated nickel dust by
increasing its overall use of nickel by  130%.

What would have happened if SEPs were not included in these nine settlements? Certainly, the
nine companies would  have paid higher penalties to the U.S. Treasury.  Beyond this, in some
cases it is possible and in some cases it  is virtually guaranteed (e.g.,  Freon users), that the
pollution prevention projects implemented  as SEPs would have been implemented by the firms
some time in the future.  Several firms stated that they would have eventually implemented the
projects.   This issue will be examined in a subsequent section.  It is relevant to  consider the
environmental benefits of accelerated implementation where projects would most likely have been
implemented eventually.   The environmental benefit of accelerated elimination of long-lived
ozone-depleting substances-the outcome of five SEPs studied here~is probably most profound.

All but one case study consisted either entirely or partially of .multi-media pollution prevention
projects,  i.e., they  reduced  or  eliminated  two or more  of the following:  emissions to  air,
emissions to water,  generation of waste, and exposure of workers to hazardous substances.  The
exception is the gasket reformulation project implemented as a SEP by LM which was designed
as a VOC reduction measure and had no positive impacts on other media.  None of these SEPs
with multi-media impacts, however, were explicitly negotiated via a multi-media  enforcement
initiative.

6.  Source of the Technical Idea

Case study companies sought and obtained technical ideas from:  their own staff, environmental
consultants, technical consultants, trade journals, vendors, and their EPA case officer.  Several
companies used more than one source.

Companies switching from organic solvent to aqueous degreasing relied heavily on the expertise
of equipment/chemical vendors.  MFC learned of trivalent chromium technology from the
chemical supplier.   One company, MDM,  saw an advertisement for deionized water cleaning
       Ibid.
                                         A-33

-------
equipment in a trade journal.  One company, LM, used a technical rather than environmental
consultant, to help with equipment design.

In only one  case, CMPM, did the case officer play a significant role in providing technical
expertise and specific suggestions. In the case of MFFM, all technical ideas contained in the SEP
came from an environmental consultant hired by the firm.  The company did not feel that they
had the necessary expertise to develop pollution prevention ideas.

Most case study firms stated that they would prefer not to  involve the agency in the process of
developing technical proposals for a SEP, particularly if it would require repeated agency site-
visits.  Many of these  firms typically had, or quickly  developed,  project ideas that were
on/consistent with their long-term critical technology path.  One firm stated that they would not
reject a good idea provided by the agency, but they were certainly not looking to the agency for
ideas.

In one  exceptional case, MMC,  company representatives  indicated that they sought technical
assistance from  the regional case officer but the case officer was unwilling to  provide help.
MMC's manufacturing engineer was seeking (and was strongly encouraged by the agency to seek)
alternatives  to   1,1,1-trichloroethane-based  cleaning  systems for  technically  demanding
applications, at a time when  aqueous and semi-aqueous technology was fairly immature.

Several case officers reported that  they were reluctant to  provide  technical advice for two
principal  reasons. First, they are concerned that if the company follows their advice and the
project  fails, the case will be jeopardized and the case officer will be reprimanded.  Second, :
because companies understand their  processes better, they are in a  better position than case
officers to develop appropriate and creative technical ideas.  A suggestion from  a case officer
may also short-circuit the company's own creative technical process and lead to a less innovative
and/or less effective project.  Generally, case officers prefer to have the violator propose a SEP,
and  then  once proposed, the case officer can perform their role as evaluator of the project's
environmental merit and technical feasibility.

The role  of the environmental consultant19 in the CMPM and MFFM  cases was particularly
important and worth noting.  At  the outset of the enforcement process,  neither  company was
familiar with pollution  prevention concepts or  techniques, nor did  they  have the technical
capability to develop or implement prevention projects. Therefore, these companies entrusted
their hired consultants with the development of project proposals and implementation during the
settlement process.  In addition, the  regional negotiators,  knowing that the companies  lacked
necessary capabilities, openly relied on the expertise of the consultants (and in some ways used
the consultants as neutral arbiters) and thereby invested these consultants with significant power
in the settlement process. These factors elevated the role of the consultants in this process and,
19
       By environmental consultant, we mean consultants engaged primarily in studies, engineering design, and
implementation projects for environmental compliance, remediation and pollution prevention.

                                           A-34

-------
 to  a large  degree,  the  outcome  was determined  by the consultant's knowledge, expertise,
 experience with specific technologies (e.g., baffle collection system for paint overspray), and
 technical orientation (e.g., waste  minimization vs.  product reformulation), rather  than the
 knowledge, etc. of the companies.

 In the case of 1C, the environmental consultant designed the SEP and assumed a primary role hi
 monitoring and reporting project progress during the implementation phase.  It may be that the
 focus in this case-waste minimization as opposed to more "up-stream" process changes-is a
 result of the technical orientation of the consultant rather than a factor of what made most sense
 from a technical/environmental and  economical standpoint.   If this is so,  both the lack of
 technical expertise within the company and the orientation of the consultant may help to explain
 why the projects implemented are not performing well environmentally  or economically.

 At first, CMPM's environmental consultant-a geotechnical/environmental engineering firm-took
 a major role in making technical recommendations for bringing the company into and beyond
 compliance.  The consultants recommended  a  $250,000  combined-flow treatment plant that the
 company realized  they  did not need.20  This  realization came about as a result of a process
 investigation that the company performed at the request of the regional case officer.  At this
 point,  the company  lessened the role of the hired consultant and, to a  significant degree, the
 regional  case officer assumed the consultant's role in developing pollution prevention options.
 The outcome of the case—a SEP consisting mainly of the redesign of several rinsing and coating
 lines in the metal finishing area-is largely a function of the case officer's expertise.  The case
 officer had just finished a year-long rotation with  the state's pollution prevention  technical
 assistance program which has participated in numerous metal finishing, plating/rinsing redesign
 projects. According  to CMPM, the regional  attorneys trusted the consultants and therefore, they
 assisted the company throughout much of the  negotiation process by helping to win EPA approval
 for  the technical changes that the company sought to implement.

 In contrast to 1C and CMPM is the case of PMMC.  PMMC hired an environmental consultant
to perform an audit  (one part of the SEP), but all of the pollution prevention  ideas included in
the  audit came from within the plant.  The consultant served primarily-to endorse the  ideas.  It
 is interesting to note that in this case,  the company became extremely motivated by the success
 of the pollution prevention projects implemented in the SEP.
7. Type of Pollution Prevention Implemented in the Case Study Firms

The case studies contain a wide array of pollution prevention techniques, including:  chemical
substitution, product reformulation/redesign, process modifications to conserve water/energy, and
waste reduction measures.
       If CMPM built this plant, they would have had significantly less incentive to implement pollution prevention
in the context of the SEP and into the future.

                                          A-35

-------
 Six SEPs dealt with chemical substitution in cleaning processes.  Four consisted of substitution
 of chlorinated organic  solvent-based cleaning/degreasing systems with aqueous/semi-aqueous
 degreasing or deionized water-based processes. In one case, PMMC, the company switched its
 tapping  fluid  to  an aqueous formulation which enabled  them  to  shut-down  their  1,1,1
 trichloroethane degreasing unit—formerly needed to remove an oil-based tapping fluid.

 Three cases involved chemical substitution in non-cleaning processes. MFC substituted trivalent
 chromium for hexavalent chromium in its chrome plating line. PMMC replaced its ammonia
 sintering atmosphere with a safer blend of nitrogen and  hydrogen gases.  BKPM eliminated
 chlorine use in bleaching by making significant  changes to the chemistry of its pulping and
 bleaching processes.

 Three cases involved product reformulation/redesign (usually necessitating process changes as
 well). LM reformulated their gasket coating material to eliminate VOC-producing heptane from
 the recipe.  This change required modifications to drying equipment. 1C agreed to reformulate
 their coating in order to eliminate the toluene coating vehicle. This change required significant
 equipment redesign.  MFC  reduced lead contaminated dust generation by redesigning their
 product. They increased the thickness of the nickel plate on the product to improve surface finish
 so that a larger percentage  of parts do  not need polishing—the dust-generating process.  This
 change also required significant process modifications.

 Two  cases  involved process modifications  to conserve water  and energy, and  to  reduce
 wastewater.  CMPM redesigned rinsing  systems on several process lines to conserve water and
 reduce wastewater discharge.  PMMC implemented a closed-loop cooling system.

 One case, MFFM, implemented a SEP consisting of several waste reduction measures designed
 to reduce organic solvent and paint waste generation; these included a solvent recycling system
 and a paint overspray recycling system (baffled collection system).

 8.  Innovation vs. Diffusion and the Locus of Technological  Change

 The technological  changes undertaken by case study firms can be categorized by a framework
 that classifies  pollution prevention projects according to the  locus  and innovativeness of
technological change. By locus we mean whether the change was made to a primary, secondary
 or ancillary production process.   A primary process is one  which yields the key functional
property or properties of the product (i.e., defines the product).  Using the example of a steel
 bolt, the primary production process is the casting of the part.   An example of a secondary
process is the metal  plating  of the part.  Plating may provide a functional (e.g., non-corrosive)
 or aesthetically-pleasing finish, but it is not primary to the function of the product. An ancillary
process is,  for  example,  cleaning of the bolt prior to  plating.   Ancillary does  not mean
 unimportant. As any metal  plater will tell you, dirty parts do not plate properly.

 Innovation is the  first  commercial application of  a new technical idea.  To categorize the
innovativeness of the technological change, we use three general headings:  major  innovation,
                                          A-36

-------
  incremental innovation and diffusion. Major innovation involves a significant shift in technology
  incremental innovation involves smaller changes or the adaptation of existing technology, and
  diffusion  is  the  widespread  adoption of existing  technology  (i.e., involving  little or  no
  innovation).

  When the "locus" and "innovativeness" characterizations of technological change are combined
  we produce the three-by-three matrix pictured in Table A-4. Projects that are located in the upper
  left-hand corner of the matrix, i.e., major innovation in primary production processes, represent
.  dramatic changes m the core technology of the firm.  Generally, these projects tend to require
  relatively high capital investment and pose greater risk to the firm, particularly when changes in
  product characteristics may disrupt established markets or when new technical expertise is needed
  and old expertise  becomes obsolete.21

  When we locate the technological changes made by case study firms within this matrix (Table
  A-4), we can  see that the majority of changes are diffusion driven, while a smaller number can
  be  considered incremental  innovations and  only one-BKPM--can  be considered a major'
  innovation. There is a fairly even distribution of technological changes across the spectrum of
  primary, secondary and ancillary processes.

  When this distribution is considered in the context of the selection criteria used to choose  case
 studies, we note that although we selected me most innovative projects for study, our sample was
 largely made up of diffusion-driven technological changes.  In addition, by seeking case studies
 involving process redesign and product reformulation, our sample contains a significant number
 of changes to  primary  or secondary production processes. If we had used a random case study
 selection process, our sample would have been much more heavily weighted toward the lower
 right-hand corner of the matrix, i.e., diffusion-driven changes to ancillary production processes
 since a  large number of SEPs consisted of the replacement of organic solvent-based cleaning
 systems with aqueous/semi-aqueous-based systems.

 In Section 14  below, we discuss the length of the project implementation period as a factor in
 the inclusion of innovative projects in enforcement settlements.

9.  Technology Transfer Benefits

In  two cases, CMPM and MMC, the companies have  transferred the ideas for solvent use
reduction and water use reduction, respectively, to other plants. The SEP implemented in the
PSSC settlement included the substitution of aqueous cleaning systems in both the subject plant
and another plant in another state and EPA region (even though no violation had been cited in
the second region).

1C and LM will evaluate the success of the SEP projects to decide whether to implement the
technology on other product lines within the subject  facilities. In two cases, MFC and PMMC,
there is particularly significant potential  for technology transfer to other  firms since MFC
participates in a state-sponsored pollution prevention group of industries and uses the state
                                          A-38

 In the case of MDM, the company will not implement the deionized water degreasing system in
 the subject facility,  since this facility will  soon close.  However, the company will seek FDA
 approval to install the system in a new facility that will replace the production capacity of the
 subject plant.

 Finally, the technology transfer benefits arising from the  implementation  of TGF pulping in1
 BKPM are quite significant.  When the project is completed, BKPM will be the first mill in the
 U.S. to produce bleached kraft pulp without the use of chlorine. Since the company has disclosed
 information regarding process changes that they are implementing, the project will certainly push
 an important technological/environmental frontier in pulp and paper industry.


 10.  Organizational Change                                                  ;     ,/

 In our interviews with case study firms, we attempted to identify whether and how the company
has made organizational changes as a  result of implementing pollution prevention  SEPs or
injunctive relief projects. It is difficult, in some cases, to determine whether changes made were
a result of implementing pollution prevention or a result of the enforcement action in general.
With this caveat in mind, this section contains an overview  of the organizational changes made
by case study firms as communicated to us by the companies.

              In the case of PMMC, the President's perception of environmental investments has
       changed.  He now believes that ii is economically  sensible  to stay one step ahead of
       environmental regulations by eliminating hazardous operations.

       •       CMPM increased their environmental staff by adding one full time engineer and
       three part-time technicians.                           ..    . ,,  ',,:  .,   .  ,        ,.„.„.,'

             Through  the  SEP process,  technical staff  at CMPM and  MMC developed,
       knowledge and skills to enable them to pursue pollution prevention beyond the SEP, and
       they are applying their abilities  to  management goals of total elimination of organic
       solvents and zero-discharge, respectively.

             MFFM's SEP contained specific organizational change initiatives, proposed by the
       firm's  environmental   consultants,   including pollution prevention  training  and  the
       promotion of plant engineer to vice president for manufacturing and environmental quality
       to carry out a pollution prevention policy and program.

             It was not apparent that the SEP process catalyzed organizational change in MDM.
       Prior to the enforcement action, a new state hazardous waste reduction law motivated the
       company to reevaluate their approach to environmental compliance and the true cost of
                                         A-39

-------
       the materials they use.  They had already made significant strides toward reduction of
       Freon use and pollution prevention in general.

       •      BKPM had also implemented many process changes, prior to their consent order,
       to improve  the  efficiency  and reduce the waste generated by its processes.  Their
       experience in seeking EPA approval for the TCP project has changed their views on the
       best way to approach regulatory matters in the future.  They will seek to involve technical
       people only in initial discussions with EPA and bring attorneys in later on in the process.

       •      Two companies have instituted new policies that prohibit new chemicals from the
       plant without approval of environmental personnel.
              Two companies started working with state pollution prevention technical assistance
       offices.

       •     No organizational change was apparent in either LM or PSSC.

It is also important to consider whether in-house counsel or retained private bar were supportive
or skeptical of SEPs and whether their views changed. With respect to in-house counsel, we have
only one case upon which to draw insight.  In the case of MDM, we interviewed the company's
in-house corporate environmental attorney who played a significant role in negotiating the SEP.
The attorney was, and continues to be, supportive of the SEP policy as a way to recognize the
efforts of a violator (via penalty mitigation) to make  environmental improvements through a
project that is beneficial to the company as well.

The majority of case study firms relied primarily on outside counsel during the negotiation
process.  The next section considers the  role of outside counsel in the settlement process.
11. The Role of Outside Counsel (Retained Private Bar)

Six out  of the  ten  case  study  firms  stated  that  their  outside counsel was instrumental in
negotiating SEPs and, in particular, helping to establish implementation schedules, milestones,
and stipulated penalties.  The following summarize relevant portions of our interviews.

       •       MFC  stated  that they had  a good outside attorney—with  experience in
       environmental litigation—who was instrumental in crafting the company's SEP proposal.

       •       MDM's in-house environmental counsel gives substantial credit for the successful
       inclusion of the SEP to their outside counsel.  The idea of a SEP came out of an initial
       meeting between EPA negotiators and the outside attorney who conveyed to the company
       that the  agency  was very interested in including  a pollution prevention SEP  in the
       settlement and asked the company if they had an appropriate project.  The attorney was
       both assertive and creative in his dealings with the  company and EPA and he managed
                                         A-40

-------
        to work out an agreement between the two parties despite the difficulties that arose over
        the implementation schedule.

              According to EPA negotiators, MFFC's outside counsel was formerly with  the
        U.S. Attorney General's Office and had worked on EPA settlements in that capacity. She
        was very familiar with  the settlement process and this made the negotiations  much
        smoother.  The region considered her involvment to be a contribution to the success of
        the SEP negotiation.

              The regional negotiators stated that LM used an outside attorney who understood
        the SEP policy well and was very proactive.

        •      PMMC stated that their outside counsel was very helpful in negotiating the SEP,
        particularly in establishing the implementation schedule.

In one case, CMPM, the firm stated that their outside attorney hampered the process because he
was unfamiliar with environmental regulations and agencies.

Although we did not have the opportunity to directly interview the outside counsels spoken of
by the case study firms and described above, our general impression is that these counsels were
supportive of SEPs.  Since the firms view SEPs positively, the outside counsels role is viewed
as a beneficial contribution since they helped the firm to negotiate a SEP. For their part, the
counsels can point to their role in reducing the penalty--a tangible "value added" service.

We were not able to determine whether the views of outside counselors changed in the course
of the settlement process.

12.  Change in Vendor/Consultant Relations

Two case provide contrasting experiences in changed relations with consultant/vendor. CMPM
was  dissatisfied with their technical consultants~a geotechnical/environmental engineering
consulting firm that  contributed to some degree with process change ideas~by reviewing and
modifying recommendations from the EPA case officer-but largely recommended traditional
technical problem-solving approaches. The company would be hesitant to use them again. LM
was  very  pleased  with  their  technical consultants who were  knowledgeable about  both
manufacturing technology and environmental  regulations.

Two companies now have begun to use state pollution prevention technical assistance programs.
MMC hired a consulting branch of a chemical manufacturing company.  MMC's manufacturing
engineer has found that his knowledge of pollution prevention technology has enabled him to  be
a better evaluator of technical options for his company than these potentially biased consultants.

In four  cases, no change  in vendor/consultant relations was  apparent.
                                          A-41

-------
13.  Projects Not Completed Under the SEP

In two cases, 1C and MDM, the companies did not fully implement the SEP projects within the
established timeline and, as  a result, paid stipulated penalties to the agency.  During project
implementation, 1C experienced unanticipated technical problems in using their existing coating
equipment to apply the new coating formulation.  Therefore, they were not able to meet the SEP
implementation deadline. Despite the regions' willingness to grant an extension, the company
paid the penalty to eliminate the SEP deadline pressures.  They are planning to  re-initiate  the
project in the near future since they consider it to be a "bonafide win-win situation for  the
environment and [their] enterprise."

MDM has chosen not to purchase the deionized water cleaning  system for the subject plant
because they will be closing the subject facility in February of 1994 and will be moving its
operations to another plant.  However, given the success of the technical evaluation conducted
under the SEP, the company will seek FDA approval for the deionized system at the new site and
implement it if approval is granted.22

14.  Time to Implement the Pollution Prevention Project

For each case study,  Table A-5 below presents information on the timeline established in  the
consent agreement and final order (CA/FO) for  SEP/injunctive relief project implementation.
Specifically, the table contains: the date of the agency's complaint23, the date of the CA/FO (i.e.,
the date it received final signature(s)), and the implementation deadline contained within  the
CA/FO.

By reading  the notes that accompany the entries, one  can see that these dates do not always
present a clear picture of the actual time taken to implement the projects.  In three cases—CMPM,
MMC, and PSSC~the companies began implementation of the projects prior to the finalization
of the CA/FOs. In two  cases~IC and MDM~the projects were  not completed  as SEPs (see
Section 13 above). Looking only at those SEPs where project implementation began at or near
the CA/FO date, and was completed under the agreement (i.e., LM, MFFM, MFC, and PMMC),
implementation periods ranged from 3 to 17 months.  The shortest period,, 3 months for the MFC
case, is a result of the fact that the company needed to compress the implementation process into
its one-week scheduled shut-down period, which fell within 3 months of CA/FO  finalization.
22
       Given the uncertainty of FDA approval and the need for R&D, agency and company negotiators put
significant effort into developing the stipulated penalty schedule.  Stipulated penalties did not appear to be a major
concern, or to require much negotiation effort, in other cases.
21
       The agency files a complaint, after an inspection, if violations were found during the inspection. The
complaint typically contains the findings of the violation, notice of the proposed assessment of a civil penalty against
the respondent, and notice of respondent's opportunity to request a hearing on the proposed penalty assessment.

-------
The unique circumstances of each case, and the limited size of our sample, make it difficult to
draw generalizations on the length of time needed to implement projects.  However, it is worth
noting one point that relates the type of technological changes made (as discussed in Section 8
above) to implementation periods. The changes characterized as incremental innovations in Table
A-4 are: CMPM (redesign of rinse systems), 1C, LM, MDM and MFC (nickel tank extension
project), and with  the exception of MFC,  each of these  required more than one year for
implementation. The single case of major innovation~BKPM~is on a 3-year implementation
timeline.  With the exception  of 1C, agency negotiators were willing to  accommodate longer
timelines in these cases.  The approximately 10 month timeline established in the 1C case was
a factor in the company's inability to complete the project as a SEP. These observations provide
a preliminary indication that innovative projects may often require more than the "maximum 1-
year implementation timeline rule-of-thumb  that is often applied by agency negotiators.

15. An Examination of Whether Pollution Prevention Projects Have Been Implemented Without
the SEP

Most of the projects implemented as SEPs had been considered by the  case study firms before
they were cited for violations by the agency.  It is difficult  to know whether, and when, these
projects might have been undertaken if the regions  had not granted penalty reductions in
exchange for the firm's commitment to implement the projects. By examining the information
that the companies provided during our interviews, we can gain insight into this question.

       •      1C considered reformulating their coating prior to the SEP, but the concept and
       implementation had been accelerated through the SEP process in two principal ways: the
       project was initiated sooner and it maintained high priority status despite difficulties in
       development and pilot testing.

       •      LM had considered the gasket formulation project prior to the enforcement action
       and may have otherwise implemented it. The SEP provided an impetus to undertake the
       project and was, from  the company's perspective, an alternative to litigation over the
       penalty amount and to spending additional money on attorneys'  fees.

              The projects implemented by PMMC under the SEP policy, had been proposed by
       various members  of the company  (in manufacturing) prior to  the issuance  of the
       complaint  The SEP process was the necessary impetus for implementation.

       •      In the months prior to the complaint, MDM explored the possibility of eliminating
       freon use in degreasing through the substitution of a deionized water degreasing system.
       They began conducting first-stage evaluations of the performance of the equipment on the
       company's products.

       •      MMC's plant engineer stated that the plant would have  eventually moved to
       eliminate their use of 1,1,1-trichloroethane, particularly given the increasing cost of the
       material. The SEP process was considered a stimulus.
                                         A-44

-------
              The facilities manager at PSSC stated that the SEP did not accelerate the aqueous
        degreasing system; the company would have implemented the project on roughly the same
        schedule without the SEP.

              Prior to EPA's complaint, CMPM realized their water usage costs were high and
        that they  should  reduce water consumption but had made no efforts to do so.    The
        company stated that EPA compelled them to implement water-use reduction measures far
        in advance and in excess of what they would have done without the enforcement action.

        •      MFC had reviewed vendor information on trivalent chromium plating prior to the
        complaint but there were no plans to convert over at that time since the trivalent system
        produced an unacceptable surface finish. They felt able to propose the trichrome system
        as a SEP because by that time, the process had been sufficiently improved.

              It  is unlikely  that MFFM  would have  implemented the pollution prevention
        measures without the SEP.

              The EPA case officer believes that BKPM chose to implement the TCP project to
       meet the toxicity limits in the consent order in anticipation of state promulgation of new,
        stringent effluent  limitations for dioxin.

It is difficult to evaluate the validity of these statements particularly because discretionary projects
(e.g., many pollution prevention projects)  are  often carried along  from year-to-year  and only
implemented when and if the will and resources exist to do them. In many cases it appears that
the SEPs serve as a catalyst to pollution prevention implementation by overcoming financial and
institutional barriers within firms.
D.   IMPACT ON THE FIRM

There are many impacts on the firm stemming from the inclusion of pollution prevention in
enforcement. In this section we present our observations and analysis, organized into two parts:
impact during the enforcement process and impact beyond enforcement.   We note the same
limitation of our study here as is given in Section D above, namely that the  majority of our
observations came about in the context of studying SEPs; however, we believe that most of the
conclusions reached in this section apply both to SEPs and injunctive relief.

1. The Enforcement Process

All nine SEP case study firm representatives interviewed stated that they support the SEP policy.
Whether  or not their projects were successfully implemented as spelled out in the  CA/FO,  and
whether or not they expended  far more or slightly more  resources on the project than they
received in penalty relief,  they were gratified to have had the option to implement a pollution
prevention project in exchange for some penalty reduction.  Before discussing the reasons why
                                         A-45

-------
these companies support this policy, it is important to note that while in the final analysis, the
SEPs took some of the sting out of the enforcement process for our case study companies, it did
not eliminate the very significant economic and psychological impacts associated with being
caught out of compliance by EPA.

With or without a SEP, attorney's fees and staff resources needed to negotiate the settlement take
a direct economic toll on the firm. Some firms, particularly those still in the implementation
stages of their projects, were initially reluctant to talk to us. This indicated to us that these firms
were concerned about continued agency oversight. This factor may be more pronounced in our
SEP case study firms because they tended to  be either small or medium-sized companies for
which the impact of an enforcement case was particularly  significant.

In most of our cases, the companies were pleased to have negotiated a pollution prevention SEP
because they could achieve a reduction in the fine for implementing a project that was beneficial
to them either  because the project cut their costs, eliminated a source of current24  or future
regulation, or  gave them  a competitive edge (e.g.,  switching  from  hexavalent to trivalent
chromium).  In some cases, pollution prevention projects secured a combination of these benefits.
In many cases the projects had been considered prior to the enforcement action.  The reasons why
these firms did not implement the projects prior to the enforcement action vary from the lack of
top  management  interest/approval,  to  a profitability  estimate  that did  not meet  company
performance criteria, to the absence or shortage of the necessary in-house technical staff or time
burdens on existing staff.

All companies  see SEPs as an opportunity to turn a negative situation into a more positive one..
Some companies stated that SEPs help to recognize their efforts to make improvements. They
rekindle staff morale because they send out a  message that while the company broke the law,
EPA reduced the fine because the company elected to implement an environmentally beneficial
project,

2.  Beyond Enforcement

While the pollution prevention projects themselves create environmental benefits, greater benefits
may be realized if pollution prevention implemented in an enforcement context is a catalyst for
additional prevention beyond the enforcement  process.  The discussions on technology transfer
and organizational change in Section C demonstrate that many of the firms studied have taken
or are working toward, further pollution prevention steps and that these steps seem to be linked
to their experience with SEPs.

It is difficult to tell, at this stage, which firms will implement the most pollution prevention
beyond their SEP/injunctive relief project. It appears that within the most active firms-CMPM,
24     This does not mean being required by the Agency to implement the project under current regulations.
Rather, this refers to, for example, eliminating a wastewater pollutant for which the company has a permitted
discharge limit.  The SEP policy explicitly excludes projects that are required by regulation.

                                          A-46

-------
 MFC, MMC-there is great potential for fur-tiiec pollution prevention.  At this early stage, we
 cannot conclude that the type of project impkmented~classified by the framework presented in
 Table A-4--is a strong determinant of the company's pollution prevention activities beyond the
 enforcement settlement.
 3-   The Impact of Pollution  Prevention  SEPs on the Deterrence Effect  of the  Agency';
 Enforcement Programs
Based on our interviews, we learned that none of the case study firms knew of the SEP policy
prior to EPA's inspection.25  This is not surprising since the policy is relatively new and many
of the inspections were conducted between 1988-91,  We can be reasonably sure, that within our
sample, knowledge of the  SEP policy did not act to compromise the deterrence effect of the
agency's enforcement  programs.  This profile is changing.  According to one EPCRA  case
officer, several attorneys representing EPCRA 313 violators  have asked him at the outset of the
negotiation process whether a  SEP  can  be included in the settlement  As more arid more
companies and corporate attorneys learn of the SEP policy this may become the norm.

It is  difficult to predict whether and  to what degree, the  SEP policy will compromise the
deterrence impact of the agency's enforcement programs. Some critics believe that firms  will
make a calculated decision to save money by not investing in pollution control or prevention
because the financial risk of enforcement coupled with the "relief offered through SEPs is less
than the savings  associated with non-compliance.          "

Under this  scenario, our research tells us that these incentives for non-compliance should be
weighed against  incentives  for compliance, such as:

              a company's desire to  avoid bad publicity and the associated negative outcomes
       from their geographical community, community  of manufacturers, and current/potential
       customers

              a company's desire to avoid future regulatory  scrutiny and the financial  risk  that
       such scrutiny poses

             a company's desire to avoid the expenditure on attorney's fees and staff resources
       in negotiating an enforcement settlement

             a company's  desire to avoid closure costs for improper waste treatment operations

             the agency's right to refuse to negotiate a SEP based upon a company's prior non-
       compliance history or "bad faith" negotiating posture.
      One firm, MFC, learned about SEPs after the EPA inspection and before the first settlement conference.
                                         A-47

-------
The collective experience of our case study firms illustrates a different scenario since these firms
believed, through their ignorance or misunderstanding  of the regulations, that they were  in
compliance.  Thus, for them there is no balance sought between incentives for compliance and
incentives for non-compliance; SEP policy would not be expected to encourage non-compliance.
