Introduction and Overview
Superfund is the nation's program for cleaning up
uncontrolled hazardous waste sites. Established by the
Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) of 1980,
Superfund is in many ways two programs. The Removal
Program responds quickly to emergencies where
hazardous materials are, or may be, released. The
Remedial Program is dedicated to long-term cleanup of
hazardous waste sites that pose the greatest threat to
public health or the environment. Removals can occur
anywhere, at any time. Federally funded remedial
actions are limited to sites on the National Priorities List
(NPL).

The Superfund process is rigorous and detailed. It has to
be to ensure that the greatest protection is afforded the
public and the environment, while at the same time the
rights of Potentially Responsible Parties (PRPs) and other
participants are protected. The flow chart below shows
the Superfund cleanup process. The major steps in the
process are:
Site discovery and investigation.
EPA evaluation of possible hazards from site
contaminants and, if warranted, addition of the site to
the NPL. Sites ineligible for federal cleanup are
referred to state or local government, business, or
individuals for cleanup.

Negotiations to compel-Responsible Parties (RPs) to
pay for cleaning up the hazardous waste problems they
helped create.
On-going community relations.
Thorough studies to develop detailed site
characterization in order to determine which cleanup
methods may be most effective, given the contaminants
present and their potential harm to public health or the
environment.
Selection, design, and implementation of a cleanup
plan, including periods of public comment on proposed
cleanup techniques.
Follow-up to ensure cleanup is effective.
EPA records in its CERCLIS database every
hazardous waste site considered for a Superfund
cleanup and every site where a removal action is
performed. (CERCLIS stands for the
Comprehensive Environmental Response,
Compensation, and Liability Information System.)
The system tracks the identification, evaluation,
and, if necessary, cleanup of hazardous waste sites.
Whether a site requires a short- or a long-term
cleanup is determined by the oil and hazardous
materials National Contingency Plan. The
Remedial Project managers in each EPA Region,
who oversee cleanup efforts, add information about
trie sites they manage to CERCLIS. Currently, there
are 35,984 sites in CERCLIS. The Superfund Site
Tally shows the current status of each CERCLIS
site.
More than 90 percent of the sites in CERCLIS have been
evaluated to determine whether they pose immediate
threats to public health or the environment. Emergency
removals have been, or are being, taken where
warranted. NPL sites are inspected at least once every
two years to determine if changing conditions mean a
removal action is required.
The hazardous waste sites on the NPL are the nation's -
worst. They are eligible for federally funded cleanup,
although Superfund's "enforcement first" policy means
that Responsible Parties (RPs) pay for as much of the
cleanup work as possible. But no matter who pays for, or
performs, the cleanup work, EPA is in charge of selecting
cleanup methods, setting, cleanup levels, and overseeing
site work to make sure sites are safe and people and the
environment are protected.

This report documents the progress Superfund is making in fulfilling its mission of protecting people and the environ-
ment from exposure to hazardous waste. The Superfund Progress Report on this page summarizes these activities, and the
sections that follow detail the progress EPA is making at each step in the Superfund process.
It is important to note that those 1,275 NPL sites have been placed on the list in phases with the most recent addition of 30
proposed sites in FY 92. Sites are not eligible to receive long-term funds until they are listed on the NPL.

Emergency Removal
The Superfund Removal Program
responds to short-term emergencies that
involve hazardous materials and threaten
public health. By law, they can take up to
a year to finish and can cost as much as $2
million. However, exemptions to this can
be granted. By law, EPA's removal
activities can include:
Evacuating, if necessary, people living
near a hazardous materials emergency.
Removing the hazardous substances
from the area to be disposed of properly.

Posting warning signs and taking other precautions to keep people and animals away from hazardous waste sites.
A single hazardous waste site or accidental spill may require more than one removal action if more than one pollutant is
present. The removal of pollutants that pose different hazards and require different cleanup techniques could be
considered separate actions. Each action is known as a clean-up project (CP).
While Responsible Party cleanup is desirable, the key is quick response. PRPs are encouraged to participate in the
Removal Program wherever possible, provided EPA's ability to respond quickly is not limited.

Disposition of Preliminary Assessments/Site Inspections
A Preliminary Assessment (PA) is the first
step in determining whether a hazardous
waste site requires long-term cleanup. EPA
or the State reviews site reports and
documentation to identify what hazardous
materials may be at the site and how they
may spread. They also identify who may
be harmed by the chemicals. If a PA
indicates that a site is dangerous, EPA will
conduct a more detailed inspection called a
Site Inspections (SI).
Sites determined by the PA to warrant
further inspection become the subject of Site
Inspections. In a typical SI, a Regional EPA
staff member visits a site to collect
information about its soil types, the streams or rivers that flow through or near it, the local weather, the people who live
nearby and the site's owner (s). Air, soil, and water samples taken on and off the site help investigators determine
whether hazardous materials have traveled away from a site.
Usually, the PA or SI shows that a Superfund cleanup action is not warranted. This does not mean, however, that the site
is safe. It just means that this particular site is unlikely to qualify for a Superfund cleanup. Instead, other federal
programs, or state or local governments, companies, or private citizens become responsible for cleaning up these sites.

EPA uses the Hazard Ranking System
(HRS) to evaluate the public health and
environmental threats posed by hazardous
waste sites considered for a Superfund
cleanup. Each site receives a numerical
score based on the likelihood that people
will be exposed to hazardous materials on
or off the site. Sites that score at least 28.50
on the Hazard Ranking System's 100-point
scale are eligible for the National Priorities
List (NPL) of Superfund sites. (The 28.50-
point cutoff has its origins in the 1980 law
that established Superfund.)
Sites that rank lower than 28.50 also may be potentially dangerous and should be considered as candidates for cleanup by
state or local government. , ...
i *
EPA also can place on the NPL sites that score less than 28.50 if (1) the Agency for Toxic Substances and Disease Registry
(ATSDR) of the U.S. Public Health Service has issued a public health advisory that recommends people be moved from
the site, (2) EPA determines that the site poses a significant threat to public health, and (3) EPA anticipates that a remedial
cleanup would be more cost effective than a removal action.
i *
The NPL is EPA's list of the nation's worst hazardous waste sites. Sites on the NPL are eligible for federally funded
cleanups. Between 5 percent and 10 percent of the sites EPA evaluates using the HRS eventually are placed on the NPL.
Currently, more than 1,200 sites are on the NPL, three times more than Congress envisioned in 1980, when Superfund
began. EPA lists sites on the NPL by state and indicates whether a site is a federal facility. About 100 sites are added to
the NPL each year, and EPA expects the NPL to grow to more than 2,000 sites by the end of the century.
Each NPL site has been assessed to determine if an emergency removal is necessary to protect neighboring populations.
And every NPL site is re-assessed at least every two years to determine if conditions have changed to warrant an
emergency removal.

NPL sites are considered for
long-term cleanup of their
contamination problems
under the Superfund
program. The cleanup
process has two major
phases. The first is the
Remedial Investigation/
Feasibility Study (RI/FS). It
includes a detailed review of.site conditions and a listing and evaluation of the possible courses of action that could
correct problems at the site. An RI/FS can begin even before a site is given an HRS score. On average, an RI/FS costs $1
million and takes 18 to 30 months to perform. Wherever possible EPA negotiates with Responsible Parties to conduct
these studies, but ultimately it is EPA's responsibility, with public input, to chose the long-term cleanup method.
Because many sites have more than one contamination problemand even a single problem has more than one aspect
EPA often breaks down the RI/FS and subsequent steps into clean-up projects (CPs). Each clean-up project is
tantamount to a phase of a particular activity. The most common CPs are the "source control clean-up project" and the
"management of migration clean-up project." The former is concerned with problems associated with the source of site
contamination; the latter is concerned with controlling the source of contaminants. Each step in the long-term cleanup of
a Superfund site may be performed separately for each clean-up project.

cleaned up and issues a
Record of Decision
(ROD). The ROD
discusses the various cleanup techniques that were considered and explains why a particular course of action was
selected. If a site has more than one CP, a ROD for each CP may be issued. The selection process solicits public
involvement, and the ROD also contains EPA's responses to public concerns regarding cleanup options for a site. Even if
responsible parties have conducted the RI/FS, it is EPA's responsibility to select the most cost-effective cleanup method
that will meet EPA cleanup goals.
Sometimes EPA determines that no cleanup activity is necessary; for example, a chemical may be so diluted in ground
water that the water meets national or state safety standards. (Or an Emergency Removal Action took care of the problem
before the ROD phase was reached.) In such cases where no cleanup activity is required, EPA may issue a "no-action
ROD." (The term is a bit of a misnomer, however, for monitoring or other activities will be performed even if no cleanup
is performed.) -..
Once EPA chooses a cleanTup remedy, it must fit the technique to the site conditions. This adaptation, .called the
Remedial Design (RD), kicks off the second phase of a cleanup. A Remedial Design can take 12 to 18 months and cost an
average of $1 million. If Responsible Parties are conducting the design, it is EPA's responsibility to approve final plans
and specifications for the actual cleanup. - ... _ .
This stage, in conjunction with the actual site cleanup, is the most costly, and Responsible Party participation in this effort
is essential. Thus, EPA negotiates with Responsible Parties to conduct the Remedial Design and Remedial Action. Given -
current resource levels, EPA would be unable to achieve the progress it has without Responsible Party participation. '

The actual clean-up work at a
Superfund site is done during the
Remedial Action phase. This is
when the earth-moving equipment
arrives and when necessary
structures are built to treat
contaminants on site. Depending
on the contaminants involved, and
the,treatment techniques used to
clean them up, this phase may take as long as six years to complete. If contaminated ground water must be cleaned up,
the work may continue for decades.
The cost of Remedial Actions averages $25 million. Thus, Responsible Party participation in this phase of the project is
most important. If Responsible Parties are conducting this phase, EPA conducts extensive oversight to ensure that the
remedy is implemented consistent with the ROD and the design specifications and that protective cleanup levels are
achieved.

Q
Whenever possible, EPA begins looking
for PRPs before beginning any clean-up
work paid for out of the Superfund Trust
Fund. PRPs are liable for all costs
incurred by the Federal Government.
The search for PRPs can be lengthy, and
site cleanup often begins before all PRPs
are identified. In any event, the search
for PRPs and the negotiations to get the
site cleaned up will not delay work to
reduce imminent threats to public health.
Once PRPs and RPs are identified, EPA
will attempt to negotiate consent decrees
with them. These documents specify the
duties and responsibilities of each RP
regarding a cleanup. If consent
negotiations fail, EPA can issue a
unilateral administrative order for
cleanup. The Agency also may begin
cleaning up the site, then sue the RPs to
recover its costs.
EPA can refer to the United States
Department of Justice for prosecution
cases against RPs who fail to comply
with federal cleanup orders. Under the
Superfund law, EPA can recover its
cleanup costs plus triple that amount in
damages for those that fail to comply
with these orders.
