                                           Quick Reference Fact Sheet
    Section 121(d) of CERCLA, as amended by the 1986 Superfund Amendments and Reauthonzauon Act (SARA),
requires that on-site remedial actions must attain (or waive) Federal and more stringent State applicable or relevant and
appropriate requirements (ARARs) of environmental laws upon completion of the remedial action. The revised National
Contingency Plan of 1990 (NCP) requires compliance with ARARs during remedial actions as well as at completion, and
compels attainment of ARARs during removal actions to the extent practicable, considering the exigencies of the situation.
See NCP, 40 CFR section 300.415(i) (55 FR 8666, 8843) and section 300.435(b)(2) (55 FR 8666, 8852) (March 8, 1990).

    To implement the ARARs provisions, EPA has developed guidance, CERCLA Compliance With Other Laws Manual:
Parts 1 and II (Publications 9234.1-01 and 9234.1-02), and has provided training to Regions and States on the identification
of and compliance with ARARs. These "ARARs Q's and A's' are part of a series of Fact Sheets that provide guidance on
a number of questions that arose in developing ARARs policies, in ARARs training sessions, and in  identifying and
complying with ARARs at specific sites. This particular Q's and A's Fact Sheet addresses the Fund-balancing waiver, which
is one of  six statutory waivers that may be invoked to allow the selection of a remedy that does not meet all ARARs.
Ql.  What is the Fund-balancing waiver?
     work?
How does it
     The Fund-balancing waiver is one of the six statutory
     waivers  that  may be  invoked  under  specified
     circumstances  to allow selection of a remedy that
     does not meet all  ARARs (see CERCLA Section
     121(d)(4)(F)).  A  waiver based on Fund balancing
     first appeared in the 1985 NCP at 40 CFR section
     300.68(i)(5)(ii).  The concept of a Fund-balancing
     waiver was codified by the Superfund Amendments
     and Reauthonzation Act  of  1986 (SARA), which
     amended the Comprehensive Environmental  Re-
     sponse,  Compensation,  and Liability Act of 1980
     (CERCLA) (see Highlight 1  for specific statutory
     language and citation).

     The Fund-balancing waiver may apply when the costs
     needed to meet an ARAR for an action would be so
     high as  to threaten the  availability of Fund monies
     for remedies at other sites (see Preamble to the NCP,
     55 FR 8666, 8750). Highlight  2 provides an example
     of the Fund-balancing  waiver.  The waiver applies
     only  to Fund-financed  remedial  actions  under
     CERCLA Section  104.   Even  when the waiver is in-
     voked, the alternative remedy selected must still be
     protective of human health and the environment and
     meet all other standards (e.g., cost-effectiveness,
     permanent  solutions, etc.).  (See Preamble to the
     NCP. 55 FR  8666. 8750.)  Regions should consult
     with  Headquarters when considering use of this
     waiver.
Q2. What is the purpose of the Fund-balancing waiver?

A:  The purpose of this waiver is to ensure that EPA's
    ability  to  carry out  a comprehensive  national
    response  program  is  not compromised  by  a
    disproportionately  high  expenditure at a  single
    Superfund site.
                       Highlight I: STATUTORY LANGUAGE

                     Section !21(d)(4)(F) of CERCLA, as amended,
                  states that a remedial action not meeting an
                  ARAR may be selected if:

                     "in the case of a remedial action to be
                     undertaken solely under Section 104 using
                     the Fund, selection of a remedial action that
                     attains such level or standard of control will
                     not provide a balance between the need for
                     protection of public health and welfare and
                     the environment at the facility under con-
                     sideration, and the availability of amounts
                     from the Fund to respond to other sites
                     which present or may present a threat to
                     public health or welfare or the environment,
                     taking into consideration the relative
                     immediacy of such threats.*

-------
Q3. When should the Fund-balancing waiver be
considered? Is there an absolute threshold for
Invoking the waiver?
A. The Fund-balancing waiver is to be routinely con-
sidered when the cost of meeting an ARAR for an
operable unit is four times the national average cost
of remediation of all operable units. (See Preamble
to the NCP, 55 8666, 8750.) However, there is
no set amount at which the waiver must be invoked.
Currently the threshold for considering the waiver is
4 x $14.4 million, or $57.6 million. This average cost
for an operable unit is based on the Outyear Liability
Model (OLM), which is EPA ’s approach to esti-
mating its long-term resource needs. The average
cost figure was developed through an analysis of
nearly 200 Records of Decision (RODs) that have
been signed since the passage of SARA (i.e., FY 1987
to present). As a group, this body of documents Is
the most comprehensive and representative source of
remedial action cost estimates available within the
Agency. The OLM average cost of an operable unit
is reported in the FY 1989 Superfund Annual Report
to Congress. (Revisions will be reported in
subsequent Annual Reports and also made available
to Regions through subsequent fact sheets.)
Q4. Does the waiver have to be Invoked when the costs of
meeting an ARAR are estimated to exceed the dollar
threshold?
A. No. Exceeding the threshold establishes a presump-
tion that the waiver should be considered , but does
not require that it be invoked . In instances where the
threshold is reached but the Fund-balancing waiver is
not invoked, either the ROD or the Adminiqra ve
Record should document the fact that the waiver was
considered and provide the rationale. For aYnple,
the Region might determine that the cost of
performing this remedy is not so disproportionately
high as to threaten the availability of the Fund to
respond to other sites that may present a threat to
hnman health and the environment.
Q5. Can the Fund-balancing waiver be Invoked even
when the cost threshold Is exceeded?
A. Yes. EPA has reserved the right to invoke this
waiver in specific situations when the cost of meeting
the ARAR Is expected to fall below the threshold
but EPA has determined that the single site
expenditure would place a disproportionate burden
on the Fund. (See Preamble to the NCP, 55 EB
8666, 8750.)
Q6. Is the waiver available for other Federal agencies or
potentially responsible parties (PRPs)?
A. No CERCLA Section 121(d)(4)(F) dearly restricts
usc of this waiver to remedial actions conducted
under CERCL.A Section 104 and financed by the
Fund. The waiver is unavailable to other Federal
agencies or PRPs, which use other monies for their
C CLA activities. (See also Preamble to the NCP,
55 8666, 8750.)
Q7. Most remedies have to comply with more than one
ARAR. If the Fund-balancing waiver Is being
ci Idered, which ARAR should be waived?
A. The ARAR that increases the potential rentedial
action costs by the threshold amount should be
considered for the Fund-balancing waiver. However,
the remedial action must comply with other ARARS
that do not excessively raise the cost of remediation.
Q8. Can the Fund-balancing waiver be used with other
walvvii ?
A. Yes. For example, the Fund-balancing waiver could
be used to waive an excessiveLy expensive ARAR at
the same site where it is necessary to waive another
ARAR because of technical impracticability.
Q9. Can the Fund-balancing waiver be used for removal
a ons?
A. In theoly, yes, but this is highly unlikely given the
monetaty limits and limited scope of removal actions.
It is more Likely that compliance with an excessively
expensive ARAR for a removal action would be
determined to be beyond the scope of the action, and
therefore Impracticable under the NCP. (See NCP at
40 CFR section 300.415(i)(2) and Preamble to the
Nap, 55 f 8666 86% )
mghalglit 2: EXAMPLE OF THE
BAL4 N G WAWER
At site X, a State water-quality standard was
Identified as an ARAR. Attaining this State
standard would ha required the removal and off-
site disposal of millions of cubic yards of
contaminated sed1m nis in the streams and
reservoir, at an estimated cost of more than Si
billion. The cost of attaining the ARAR exceeds
the threshold of four times the cest of a typical
operable unit, and thus, the Fund-balancing waiver
was considered. Based on an assessment of the
Fund, and needs at other sitei the Agency decided
to Invoke the waiver. The waiver allowed selection
of an alternative remedy that Involved partial
capping and surface-water diversion at a fraction of
the original cost, while still achieving protectiveness
and complying with other ARARS.

-------
Q1O. Can the Fund-b nclng waiver be invoked only at
Fund-lead orphan sites (I.e., sites where no PRPs
have been identified)?
A. No. The Fund-balancing waiver may also be invoked
at a Fund-lead site where PRPs exist and may
potentially settle. However, if PRPs do settle and
subsequently take over the project, they cannot take
advantage of the waiver — the action will no longer
be solely funded under SectIon 104 and the Fund-
balancing waiver will no longer be available.
Likewise, the waiver is not available for mired-
funding cases involving contributions by both PRPs
and the Fund. Therefore, where circumstances for
settlement with PRPs potentially exist, the Region
should anticipate this possibility by including a
contingent remedy (without the waiver) in the ROD.
11 such a contingent remedy has been included in
the ROD, and a settlement with PRPs Is reached, the
ROD should be amended to remove the waiver or an
Explanation of Significant Differences (ESD) should
be issued. The ROD should be amended if removing
the waiver would fundamentally alter the basic
features of the selected remedy. (See NCP at 40
CFR section 300.435 (c)(2)(li) and Preamble to the
NCP, 55 FR 8666, 8771-8772.) An ESD may be
issued if removing the waiver significantly changes,
but does not fundamentally alter, the remedy selected
in the ROD. (See NCP at 40 CFR section
300.435(c)(2)(i) and Preamble to the NCP, 55
8666,8770-8772.)
Qil. If the Fund-balandng waiver has been Invoked In
the ROD because a PRP settlement was antldpated,
can It be subsequently Invoked If no settlement ever
o rs?
A. Yes. If a settlement with PRPs is not reached, and
the remedy will be performed using Fund monies
under CERCLA Section 104, the Fund-balancing
waiver can be invoked by a ROD amendment or, in
appropnate cases, an ESD.
Q12 Will the answer to the previous questions ever lead
to an Incentive for PRPs not to settle?
A. It could. However, the statute is clear that the Fund-
balancing waiver is available o for Fund-financed
actions. Of course, if such an incentive not to settle
exists, PRPs may be encouraged to settle through the
issuance of a unilateral order and the resulting
possibility of fines and treble damages. (See
CERCLA Sections 106 and 107(c)(3).)
Q13. If a remedy Is undertaken solely usIng the Fund, and
the Fund-b ndng waiver is Invoked, can the Agency
later bring in action to re ov Its costs?
A. Yes. The fact that the statute allows EPA to select
a remedy made less expensive by the waiver does not
affect the right of the Agency to be reimbursed later
under CERCLA Section 107 for the costs of that
remedy.
Q14. What language should be used In the ROD for
invoking the Fund-balancing waiver?
A. IlighUght 3 provides sample language for various
sections of the ROD. This language is based on the
hypothetical site circumstances presented in 1 Igh -
light 2 of this fact sheet and a hypothetical State
law. For additional language, see Guidance on Pre-
paring Superfund Decision Documents (the ROD
Guldance), EPA/540/G-89, )07, July 1989, page 6-5.
