Regional Counsel, Regions I-X
     This memorandum transmits to you the Agency's "Streamlined
Approach for Settlements With De Minimis Waste Contributors under
CERCLA Section 122(g)(1)(A)."  The guidance supplements existing
guidance for de minimis waste contributor settlements and to the
extent applicable, supersedes existing guidance.

     The guidance establishes the minimum level of information
necessary before a Region can consider a de minimis settlement,
provides a methodology to construct payment matrices in
appropriate circumstances,  and encourages .Regions to take a more
active role in facilitating the de minimis settlement.

     The guidance reflects input from the Regions, Headquarters
and the Department of Justice.  We thank you for your assistance.

            STREAMLINED APPROACH FOR SETTLEMENTS WITH
                DE MINIMIS WASTE CONTRIBUTORS UNDER
                   CERCLA SECTION 122(g)(l)(A)

     This guidance sets forth the Agency's new approach to
completing de minimis settlements.   This memorandum expands
upon the information provided in the "Superfund Administrative
Improvements - Final Report  (June 23, 1993)."

     Under Section 122(g) of CERCLA the Agency may settle with
persons who contributed to a facility hazardous substances which
are minimal, both in terms of volume and toxicity or other
hazardous effects, relative to other hazardous substances at a
site.  De minimis settlements may only address a minor amount of
response costs at a site.

     To encourage more,  early, and expedited settlements, and
reduce the transaction costs of all parties, the Agency
identified several actions to improve the de minimis program
during our review of administrative improvements to Superfund.
We are changing our existing guidance to simplify the
administrative determinations for finding a PRP eligible for a de
minimis settlement, and provide opportunities for streamlining
the de minimis settlement process.

Eligibility Determinations

     The Agency's previous guidance recommended that a de minimis
waste contributor settlement should not be considered until a
waste-in list and volumetric ranking is available.  It is no
longer necessary to prepare a waste-in list or volumetric ranking
before considering a party's eligibility for a de minimis
settlement.  To determine whether a PRP is eligible for a waste
contributor de minimis settlement, a Region need only, assess the
individual PRP's waste contribution relative to the volume of
waste at the site.   Comparing these two pierces  of information
allows the Region to determine whether that party's contribution
was minor compared to other hazardous substances at the facility.
Regions should use available documentary evidence to identify the
individual amount of contribution.  Regions nay estimate the
volume of waste present at the site using several methods,
including review of site volumetric records, process engineering
information, or site sampling results.  The volumetric estimate
        To the extent this memorandum changes past Agency
procedures or policies this memorandum supersedes those
documents, and Regions should follow the directives set  forth
herein.  Otherwise,  past guidance on de minimis waste contributor
settlements remains  in effect.

     2  Generally,  the Region should then divide the individual
contribution  by the  volume of waste at the site;  this establishes
the PRPs volumetric  percentage of waste contribution.

-------
 should reflect the Region's understanding of the waste present at
 the site;  the amount does not need to be a precise figure.   In
 circumstances where it is particularly difficult to quantify the
 waste  amount (especially early in the response  process)  a Region
 may identify the volumetric estimate as a range (e.g.,  between
 50,000 and 100,000 gallons,  or batteries,  etc.).

     While it is not necessary to prepare a  waste-in list or
 volumetric ranking for determining de minimis eligibility, when
 this information is available it  should be considered  in making
 the de minimis eligibility determination.  Consistent with the
 Agency's information release  policy,  Regions should  release  any
 waste-in list and volumetric  ranking to all  PRPs.

     It is  important to  reemphasize  the Agency's  approach to the
 toxicity component  of  the  de  minimis determination.  In both our
 1987 and 1989  de  minimis guidances the  toxicity  finding is met
 when the hazardous  substances  are  not "significantly more toxic
 and not of  significantly greater hazardous effect" than other
 hazardous substances  at the facility.   For example,  if the
 hazardous substances  at a  site are of similar toxicity and
 hazardous nature, a  Region does not  have to engage in further
 evaluation  to  make  the toxicity determination.

     Once the  above  information is available, a Region needs to
determine the  appropriate cutoff for de minimis and  non-de
minimis parties at the site.  This guidance does not establish a
set percentage for eligibility for a de minimis waste contributor
settlemen^; we believe that decision  is primarily site-
specific.

     Where a Region identifies the volume of the waste at the
site as a range, they should use the  lower estimate  for
establishing the eligibility of the PRP for a de minimis
settlement.  This ensures that the party is truly de minimis.
        "Releasing Information to  Potentially Responsible Parties
at CERCLA Sites," OSWER Directive 9835.12 (March 1, 1990);
"Revised Policy on Discretionary Information Release Under
CERCLA,"  OSWER Directive 9835.12-Ola (March 31, 1993).

        "Interim Guidance on Settlements  with De Minimis  Waste
Contributors under Section 122(g)  of SARA," OSWER Directive
9834.7 (June 19, 1987); "Methodologies for Implementation of
CERCLA Section 122 (g) (1) (A) De Minimis Waste Contributor
Settlements," OSWER Directive 9834.7-1B  (December 20, 1989).

         Please  note  that statistically  (of  the de  minimis
settlements entered to date), the de minimis cutoff has ranged
from .07% to 10.0%, the mean was 1.059%,  and the median was 1.0%.

-------
For example, if a PRP contributed 500 batteries to a site where
the Region estimates that between 50,000 and 100,000 batteries
are present, the PRP's assigned volumetric percentage should be
1.0% (500/50,000).

     In determining the cutoff point, the Region needs to make a
reasoned judgment regarding the effect of a possible settlement
on non-de minimis parties.  We recognize that there may be a
certain amount of imprecision, particularly in light of the
limited amount of volumetric information available at many sites.
Detailed information and extensive supporting documentation are
not necessary for this determination, although the Region will
need to explain the basis for the identified cutoff (i.e., what
factors they considered).  If information available at the time
of settlement indicates that there is or is likely to be a large
or very large orphan share, the Region should take this into
consideration in formulating the de minimis settlement (e.g.,  by
adjusting the premium upward).  In addition, a de minimis
settlement should not foreclose the Region's ability to pursue an
enforcement action against the non-de minimis parties to perform
or finance the remedy.

Streamlining the Payment Calculation

     A. Baseline Payment

     Consistent with past guidance we suggest establishing the
baseline payment amount by applying several factors: the
individual's percentage of waste contribution to the site, the
total past costs expended and an estimate of future costs.  To
establish the future cost estimate,  Regions are encouraged to use
the "Methodology for Early De Minimis Waste Contributor Set-
tlements under CERCLA Section 122(g)(1)(A)," OSWER Directive
9834.7-1C (June 2, 1992).  This guidance reaffirms the
methodology contained therein for estimating future costs, as
well as the Agency's commitment to developing early estimates of
future costs.

     If a Region can establish an individual's percentage,
identify past costs and estimate future costs with relative ease,
based on the available information (i.e., without expending
substantial resources or time to collect the relevant data), that
is the preferred approach for establishing the baseline payment
amount.   There may be situations where  there is uncertainty in
        To identify the past and future cost baseline payment a
Region would  first multiply the  individual volumetric percentage
by the total  past cost  amount; this provides a PRP's pro-rata
share of  past costs.  A similar  multiplication would be made to
establish the pro-rata  share of  future costs.  The pro-rata share
of the past and  future  cost components are added together to form

-------
 the  overall  volume  of  waste  at  the  site  (used to establish the
 individual percentage)  or  where the future estimate of site costs
 is particularly difficult  to establish other than to estimate the
 amount within  a range  (e.g., the  remedy  cost estimate is between
 10-20 million  dollars).  In  such  situations, a Region may
 construct a  payment matrix to assist in  establishing a PRP's
 baseline payment amount.   See Attachment 1 for an example payment
 matrix.

     B.   Premium

     A Region  should assign  an  appropriate premium to the
 baseline future payment amount.  The  amount of the premium will
 often bear close relation  to the scope of the covenant not to sue
 provided to  the de  minimis settlors.   Of the de  minimis
 settlements  reached to date, the premium assigned has generally
 ranged from  50 - 100%.   In an  effort to  streamline  the process,
 Regions may  assign  a 50% premium where PRPs agree to a covenant
 not to sue which contains a remedy  cost  re-opener.  Where the
 Region offers  a covenant not to sue without a remedy cost re-
 opener (and  thus provides the settlors with more finality), the
 premium may  be closer to 100%.   Regions  should consider offering
 both options in the same settlement document (i.e.,  a menu
 approach).   A Region should adjust  these numbers to reflect other
 uncertainties or concerns.   For example,  a Region should increase
 the premium  if the  settling parties decline a previous settlement
 offer.   On the other hand,  site conditions may justify a lower
 premium.

 Facilitating the De Minimis Agreement

     To facilitate  the de minimis settlement process,  Regions may
 settle with  individual de minimis parties, settle after a de
minimis group forms, or settle with individual de minimis parties
 and combine the signature pages into one settlement document.
Although the Agency prefers settling with de minimis parties as a
group because it conserves government resources,  Regions should
 consider offering individual de minimis  settlements without
waiting for a de minimis group to form,  as this will reduce the
de minimis parties' transaction costs incurred while waiting for
 the group to form.  To reduce resource implications for de
 minimis parties,  Regions should actively assist in forming the de
 minimis group once  there is a potential  for a de minimis
the baseline payment amount.

        See "Guidance on Premium Payments in CERCLA Settlements,"
OSWER Directive 9835.6  (November 17, 1988).

     8  Of the 47  de minimis settlements with available premium
data, 29 settlements used a premium between  50 and 100%.

-------
settlement.   It  may  be  appropriate to offer the use of an
alternate dispute  resolution  (ADR) professional to assist in the
formation of  the group  and dissemination of information.

     Before the  Region  tenders a de minimis settlement offer
there are several  things the  Region should consider doing to
improve the chances  of  the offer's acceptance as well as to avert
potential controversy.  Frequently, de minimis parties are
unaware of the difference between a demand letter from a settling
PRP and an offer letter from  the government.  Moreover, some de
minimis parties  are  unfamiliar with the benefits that accrue from
settling with the  government, such as the covenants not to sue,
contribution protection and reduced transaction costs.  Members
of Congress and  other elected officials are also frequently
concerned about  the  effect of Superfund on their constituents and
thus may be another  important audience for information about
impending de minimis settlements.  Therefore, a Region should
consider developing  a communication strategy prior to initiating
settlement discussions.   In  addition,  information concerning
proposed de minimis  settlements should be provided to the non-de
minimis parties.

Elevating Issues

     Under existing delegations Regions must consult with the
Office of Enforcement and Office of Waste Program^ Enforcement
for all de minimis waste contributor settlements.    Under
Section 122(g)(4) of CERCLA,  the approval of the Department of
Justice is necessary for administrative de minimis settlements
when site costs  exceed  $500,000; the Department must approve all
Consent Decrees  regardless of site costs.  To provide assistance
in evaluating potential de minimis settlements before they are
transmitted to the PRPs, Headquarters and the Department of
Justice have each established a taskforce.   Senior managers
will also be available  to  discuss proposed settlements early in
the process.   Finally,  Headquarters and the Department of Justice
have agreed to provide  rapid elevation of key decisions regarding
the implementation of the new de minimis orocedures.
     g
        A model communications strategy for use in de minimis
settlements is forthcoming that includes a model notice letter
for de minimis parties.


         Current Agency guidance requires Headquarters
concurrence on the first de minimis waste contributor settlement
in each  Region.  Every Region has completed at least one de
minimis  waste contributor settlement.  Therefore, while only
consultation is necessary it  is important to begin discussions
with Headquarters early to ensure a quick resolution of issues.

     Set forth below is an example of a payment matrix a Region
might construct for determining a de minimis party's baseline
payment amount (i.e., the payment before a premium is assessed).
In this example,  both the individual contribution and total site
costs are expressed in ranges.  There may be situations where
only one of these factors will be uncertain, thus, a matrix would
only have one component expressed as a range while the other is
expressed as a set number.

     In designing a matrix, it may be useful to present total
site costs as one figure, or set up separate matrices for past
and future costs.  The example matrix provides payment amounts
for five classes of possible de minimis parties, ranging from
.001% to 1.00% contribution.   Classes II  through V represent
ranges of equivalent size.  We subdivided Class I into three
parts in order to tailor payment amounts more closely to the
contribution for the smallest de minimis waste contributors.
       Percentage contributions in four decimal places that end
in 5 or greater  should be rounded up to the next thousandth
(e.g.,  .0205% becomes  .021%).

-------
 In  our  example,  eligible  de  minimis parties contributed between
 .001% and  1.0%.

     The example payment  amounts  in matrix were calculated simply
 by  multiplying the  individual contribution  (expressed as a
 percent of the overall waste at the site) by the estimated total
 site costs.  The payment  amount was calculated using the average
 total site cost  in  each range and the average percent
 contribution in  each Class.  For example, the $250 payment for a
 Class I settlor  at  sites  that range from $0-10 million was
 calculated as follows: $5 million x .00005 = $250.
     2  The  range  of  contributions  provided  in this  example was
selected for two reasons. First, a separate draft guidance that
focuses on de micromis settlements may suggest that parties who
contributed less than .001% should be treated as de micromis
rather than de minimis parties.  Second, the example range
extends only to 1.0% because the average cutoff for eligibility
in de minimis settlements to date has been 1.0%.
