I.   BACKGROUND AKD PURF'OSE

     Attempts to reach settlements under  the Comprehensive

Environmental Response, Compensation, and Liability Act

(CERCLA), 42 U.S.C. §§9601 e^_sg.g. , as amended by  the

Superfund Amendments and Reauthorization  Act (SARA) of  1986,

Pub. L. No. 99-499, pose difficult problems for both the

regulated community and the Agency.  Potentially responsible

parties (PRPs) are often reluctant to settle hazardous  waste

enforcement cases because future  cleanup  costs are unknown;

they seek broad covenants not  to  sue in an effort  to provide

a final determination of the extent of their liability.

EPA, on the other hand, is reluctant to assume the risk that

further site remediation •» 111  be  required foilovmg

agreement or i,har the cost estimate is inaccurate.
                                  '    i '.cl '    , 'i
     One way to address these obstacles to settlement is for
                                  't ,
EPA to require, in appropriate situations,' a ".premium

paymem" from PRPs in exchange for the Agency assuming

future remediation'and financial-risks.  The-term "premium

payment" refers to a risk'apportionment device, similar to
                i        .1
an insurance premium, unde^ which the" risk taken by the

government .for providing  PRPs with a  release from liability

not usually available (e.g., a covenant not to sue without

the usual "reopeners" or  a covenant not to'sue for certain

types of cost" overruns) is offset by  a payment- in excess of

the cost projected to complete the remedy.  The premium

should be sufficient to compensate EPA for taking the risks

associated with the following types of contingent future
         ~-          i-               -^  _-»  ~

costs:   (1) cost overruns wh-en the selected remedy costs

more to complete than estimated;_ and  (2) additional costs

when more remedial work is required because the selected

remedy is not adequately,protective of human health and the

environment.*  .

    . The purpose of this  memorandum is to provide guidance

on the use of premium payments in CERCLA settlements.  It
     1  As discussed  in Section IV,  iflfja.  "Timing of
Premium Payment Settlements," premium payment settlements
will not usually occur until after the remedy has been
selected.  Thus, the  permanence of the remedy chosen will
not be affected by the -existence of  a premium payment and
such settlements are  not considered  to be  inconsistent  «ith
Section  122(c)(l) of  CERCLA.

       As tojfuture liability, Section I22(f)(6) provides that

  in-most-situations, a covenant not to sue for future

  liabi-lity must include a "reopener" that allows EPA to

  pursue the -settling PRPs concerning conditions that were

  unknown at the time EPA certified that the remedial action

  was complete.   Agency policy also requires that.settlements

  include a reopener to the covenant for future liability

-"where new information reveals that the remedy is not
                                          '  "  - -j
- protective ;of  human health and the environment.5
       4  In Section l22(fUl) of CERCLA,' Congress authorizes
  EPA to issue covenants not to sue for both present liability
  and future liability.  In the context of covenants not to
  sue involving .remedial action, "EPA interprets present
  liability as a responsible party's obligation'to pay those
  response costs already incurred by the United States related
  to a site and to complete those remedial activities set
  forth in the Record of Decision for that site.  Future
  liability refers to a responsible party's obligation'to
  perform any additional response activities--at- the site which
  are-necessary to protect public health and the environment."
  See EPA's '"Interim Guidance on Covenants Not to Sue Under
  Section 122(f) of SARA," 52 Fed. Reg. 28038, 28040' (July 27,
  1987).

-------
                             5

     Under Section 122(f)(6), the Agency may exclude the

"unxnown conditions" reopener from the covenant not to sue

for future liability if EPA determines that "extraordinary

circumstances" exist.6  For purposes of this memorandum, the

"unknown conditions" and the "new information" reopeners

will be treated together.  In determining whether

extraordinary circumstances exist, each case should be

evaluated using the various factors specified in Section
     6  However, under Section 122(f)(6)(B) ,  even if
extraordinary circumstances exist, the unknown conditions
reopener may not be waived if the settlement does not
otherwise provide reasonable assurance that public health
and the environment vill be protected from any future
•releases.

-------
122(f)(6)(B).7  The premium payment itself should be

considered in the analysis as well.

     If extraordinary circuihs'tances 'exist, the Agency may

which*,  when taken together, lead the Agency "'to conclude that
     7   Section 122(f)(6) refers to both the factors-"
specified in Section 122(ft(4t  and additional factors that
reiterate the guidance set forth in the Interim CERCLA
Settlement Policy.  The additional factors relate to the
volume and character of the substances at the site; to risks
associated with the strength of the government's case on
liability, ability to pay, precedential value, and
inequities and aggravating considerations; and also to
public interest considerations.  The factors Specified in
Section 122(f)(4) relate primarily to the nature of the
remedy.  They include:
     a.  The effectiveness and reliability of the remedy, in
light of the other alternative remedies considered for the
facility concerned.
     b.  The nature of the risks remaining at the facility.
     c.  Thr> extent to which performance standards are
included in the order or decree.
     d.  The extent to which the response action provides a
complete remedy for the facility, including a reduction in
the hazardous nature of the substances at the facility.
     e.  The extent to which the technology used in the
response action is demonstrated to be effective.
     f.  Whether the Superfund or other sources of funding
would be available for any additional remedial actions that
might eventually be necessary at the facility.
     g.  Whether the remedial action will be carried out, in
whole or in significant part, by the responsible parties
themselves. .
     What constitutes extraordinary circumstances must be
ba^ed on the facts of each case.

the circumstances and terms of the settlement warrant the
granting of a covenant not to sue without reopeners.8
B,   Premiums Designed to_ ftdflress. Cost Overruns
     In a settlement in which the PRPs agree to reimburse
the government for cleanup costs associated with present
liability, the issue of how to calculate as yet uncertain
costs associated with the anticipated remedy must be
addressed.  Generally, the government desires that PRPs
finance all response costs, and thus PRPs must await the
completion of the remedial action before the extent of their
present liability is established.  However, if the PRPs
would prefer to firmly establish the "price tag" for present
liability before cleanup  is completed, one option is to
require PRPs to provide funds believed to be sufficient to
cover projected cleanup costs, plus a premium to protect
against cost overruns.  Although the'government as a matter
of course seeks to avoid  assuming risks associated with the
uncertainties of cost projections, the payment of
appropriate cost overrun  premiums should ensure that,
viewing the cost recovery program as a whole, the government
is protected against those uncertainties.  Settlements which
include a premium for present liability, including cost
     8  In certain situations, EPA may reach settlements
where extraordinary circumstances exist without requiring .
premium payment.  For example, EPA may exclude the unknown
conditions reopener without a premium payment in a
settlement with a PRP who has invoiced the protection of
Chapter 1 bankruptcy laws.

 overruns premiums,  may be appropriate, but the traditional


 reopeners would be  applied to future liability in such

 settlements.


 III.  , AMOUNT OF THE PREMIUff ,PAY?lEKfT
                                            "*      * "

      As noted above,  premium payments may  se-ve two  purposes


 7-  to provide funds to protect public health  and the

 be  needed-at the site or to protect against the risk that


 site  remediation cost overruns may occur.   In evaluating  the


 offer*, EPA must determine whether the amount  of the  premium


 is  adequate given the risks assumed.  The  factors specified
                                        j       r

 be  considered in determining the amount of the premium


•payment.   The factors speci-fied in Section I22(f)(4) that


 relate to the effectiveness, reliability,  and permanence  of

 the remedy are particularly important in determining the
                                                      : i
 likelihood that additional response work may be necessary


,and the associated  possible costs.


 A.   Future Liability Premiums


      Despite best efforts .by the Agency or PRPs to design


 and implement a satisfactory remedy, future problems may


 arise at the site due to remedy failure-or mistaken


 assumptions about the effectiveness of the remedy.   In


 addition, the discovery of hew information about site


 conditions or new scientific determinations regarding what

-------
                             9
levels of contaminants present a risk to humans or to the
environment may make additional work necessary.  One way
such new information may become available is through the
Section I2i(c) five year review EPA is required to conduct
for all remedial actions at sites where hazardous substances
remain.
     In determining the amount of a "future liability"
premium, two general factors should be considered:  the
likelihood that future remediation will be required and the
cost of such remediation.  The resulting premium could be a
percentage of the total estimated cost of the remedy.
     1 •   The_.J. Ike li hood that further jremedifltiqm will J^e
required:  The need for further work may depend on the
effectiveness and reliability of the remedy.  Factors such
as whether the remedy selected has been demonstrated to be '
effective under similar conditions at other sites, whether
the remedy selected involves treatment or incineration as
opposed to containment, whether the settlement agreement
includes specified performance standards, or the extent to
which  the remedy provides a comprehensive solution to site
contamination, all bear on the level of the premium.
     The risk that further work will be required also
depends on the extent to which all relevant environmental
conditions have been discovered and evaluated.  For  example,
additional information about relevant conditions developed

-------
                              10
 during'the remedial -design phase may'enhancer.the. Agency's
 confidence in the selected remedy.
      In addition, th'e time "necessary to complete .the  remedy
• may affect the risk of further co itamination occurring.  For
 example, if a long period of-temporary storage will precede
 disposal or treatment, the premium should be calculated so
 as to protect"against releases during storage.
      2.   The cost of further  remediation;  Any premium
 payment must be based in'part  on an estimate of.the cost of
 conducting additional remedial work should the chosen  remedy
 fail to abate the hazards posed by the site.  EP&'s estimate
 should be based on a site-specific estimate of the most
 probable costs "of the additional response action.  Where the
 estimated cost of' replacing, repairing, or otherwise
 supplementing the remedy'is very-high, the government  should
 either retain the right to pursue the settling PRPs for
 additional work or costs, or require-a premium payment
 commensurate with the cost and the risk that future
 remediation will be necessary. - i"
 B,  Qost Overrun, Premiums
      The Agency also recognizes the possibility  that  a
 selected remedial action win  cost" more than'originally
 estimated because, for example, (1) the cost-estimate  was
 inaccurate or (2) estimates concerning tiie am^-nt or  type  of
 material to be treated or the1 length of time for treatment

-------
                             11
were inaccurate.9  EPA can guard against these cost overruns
by reserving the /righi. to seek reimbursement for any
overruns or by requiring an up-front payment of a "cost
overruns" premium.  The amount of the premium should be
based "on the reliability of the Agency's cost estimate,
taking into account such factors as the length of time
needed to complete the remedy and any historical data on
instances where actual costs of site remediation exceeded
projected costs.  The premium could be a percentage of the
estimated cost of the remedy based on the risk of such cost
overruns.
c.
     In determining the total settlement amount, the premium
payment must be added to the total response costs.  This
base amount to which the .premium is added should include
past costs, indirect costs, pre judgment interest, the
estimated cost of the remedy (unless performed by PRPs )  ,
oversight costs, operation and maintenance costs, and
technical assistance grants.  The total settlement amount
vould be the base amount plus the premium.  Generally, the
settlement agreement should specify which portion of the
premium payment is allocated to present liability and which
portion to future liability.
     9  If estimates concerning the amount or type of
material to be treated were inaccurate because of unknown
conditions or new information, the resulting additional
costs would be considered part of the responsible party's
future liability.

' IV.  TIMING OF  PREMIUM  PAYMENT  SETTLEMENTS	
      'The -Agency usually should  not conside^ a .premium
 payment "settlement unless  it has adequate information about
 the  idpntrty, waste 'contributions. and viability of PRPs  for
 the  sire^coricerned," and- about the costs of remediating site
 contamination.  The Agency develops;information  about PRPs
 through PRP" searches". the  remedial inve_stigation and
 T •       ,.
 feasibility study" (RI'/FS) ,  and  informatiohTgathering
 activities under  Sections  104{e) and  122(e) of CERCLA and
 Section "3007 of the Resource"Conservation and Recovery Act,
 A Nonbinding Preliminary Allocation  of Responsibility
 (NEAR), authorized by Section 122(e){3) of CERCLA,  if
 prepared, may also provide significant information-for
 evaluating"a premium payment settlement.^0
      Premium payment settlements should not be pursued until
 the  Agency is'able to determine the  likely remedial action
 and  estimate, with a reasonable degree-of confidence, the
 total cost of cleaning  up  the site,  including oversight and
 operation and maintenance.  -The Agency,usually will arrive
 at this level of  confidence only after the RI/FS and a
      10  see.  EPA's  "interim  Guidelines  for  Preparing'
 Nonbinding Preliminary Allocations  of  Responsibility
 INBAR) ," 52 Fed. Reg. 19919  (Hay  28, 1987K   Section
 122(e)(3) of CERCLA  authorizes .EPA, at its discretion,  to
 prepare an NEAR which allocates  100 percent  of  response
 costs  among PRPs in  order  to  promote and expedite  settlements

-------
                             13
Record of Decision (ROD) have been completed.11  A premium
payment settlement could be considered earlier if the Agency
is relatively confident of its ability to estimate future
response costs, and the premium payment amount reflects the
increased level of uncertainty.12
V.  Ugp OF THE
     Normally, premium payments will be made to the
Hazardous Substances Super fund.  The Agency is exploring the
circumstances under which it may be appropriate for
settling PRPs to establish site-specific trust fund or
escrow accounts.  Further guidance on this issue will. be
provided by separate memorandum.
     if the costs of the remedy exceed the recovery from
settling PRPs (including the premium), EPA will generally
seek "to recover remaining costs from other PRPs.  The Agency
may also approve comprehensive settlements in which certain
PRPs pay a premium to other PRPs who, in exchange, agree to
accept the responsibility of those premium-paying PRPs
regarding site liability, including any possible future
liability.
     H  Timing considerations for settlements with fle.
min,i,ad,,s PRPs are discussed  in greater detail  in EPA's
"Interim Guidance on settlements with D.e......Minuni^ Waste
Contributors Under Section  122Cg) of SARA," 52 Fed. Reg.
24333  (June 30, 1987) .
     12  Early premium payment settlements may also be
appropriate in exceptional  cases, such  as where bankruptcy
exists.

-------
                             14

     Normally, both the base amount and the premium will

reduce the government's "claim  for costs'associated with"

performance of the remedy.  However,' in settlements

involving a premium for future "liability, EPA'may segregate

the portion of the premium paid for future-liability.  In

certain cases, EPA may determine that it is appropriate to

require PRPs to set aside the premium in a site-specific

account established by the PRPs for use if the remedy fails.

If such an account is established, future liability premiums

would not reduce the amount owed by subsequent settlors or

non-settlors for present liability (i.e., the present -

remedy).  Rather, premiums for future liability win only

reduce subsequent settlors' or non-settlors'- future

liability when "and if additional' cleanup is required to

protect public health or the environment.  Until- then, the

government will not have accepted the premium payment..13

     Premium payments may be particularly useful in mixed
    i     ^ i    ' '   f
funding or mixed work situations.  For example, EPA may

require a premium payment from PRPs to'protect against cost
                 «.         "*     *
overruns and remedy'failure fo'r EPA's portion of the work in

a mixed funding or mixed work  site.14
     *3  'The settlement agreement also should specify how
the premium payment is to be distributed if it  is not used
for remedial activities.

     14  Where a fle minimis settlement precedes a mixed
fundin- agreement, any premium payment obtained from de
        parties would reduce the share to be contributed by
the Fund as cart of the subseauent  settlement.
