 Project Summary
 Reclamation  and
 Redevelopment  of
 Contaminated  Land:
 Volume  I.  U.S.  Case Studies
G. L Kingsbury and R. M. Ray
  The full report. Volume I of a two-
volume set, presents information on
reclamation and redevelopment of con-
taminated land in the United States.
Case studies describe land use history,
nature of the contamination, redevel-
opment objectives, site remediation,
and criteria for cleanup.
  In  numerous cases in the United
States, uncontrolled dumping and in-
dustrial spills have contaminated prop-
erties with hazardous materials (now
more than  18,000 sites  have been in-
ventoried by the U.S. EPA). Since many
of these properties are in prime urban
locations, issues surrounding the recla-
mation and redevelopment of contami-
nated properties have  assumed na-
tional importance. The principal
objective of this study has been to doc-
ument with case studies relationships
between site remediation methods,
cleanliness criteria, and redevelopment
land uses.
  After extensive interviews with  fed-
eral and state officials in all 50 states,
16 uncontrolled hazardous waste sites
were selected for detailed study. For
each of these sites, remedial actions
have been undertaken or are planned,
with some upgraded redevelopment of
the property in mind. Redevelopments
include single- and multi-family resi-
dential, recreational, commercial, insti-
tutional, and light industrial land uses.
  This Project Summary was devel-
oped by EPA's Hazardous Waste Engi-
neering Research Laboratory, Cincin-
nati,  OH, to announce key findings of
the research project that is fully docu-
mented in a separate report of the same
title (see Project Report ordering Infor-
mation at back).

Introduction
  In view of the large number of uncon-
trolled hazardous waste sites in the
United States and the extent of effort
required to properly  remediate these
sites, issues related to uncontrolled haz-
ardous waste site remediation and re-
development are of  national signifi-
cance. However, because site
remediation  and reuse are relatively
new public concerns, very little informa-
tion concerning hazardous waste site
redevelopment has previously been
compiled to  describe instances where
redevelopment has occurred following
site cleanup.  The full report presents a
beginning in  this new area.

Purpose
  The purpose of the full report is to
document the value and importance of
land reuse planning in the design of
hazardous waste remediation meas-
ures. Major^emphasis is placed on pre-
senting the  functional relationships
among alternatives with respect to site
remediation methods, cleanup criteria,
and options for reuse. The three main
objectives are to:
  1. identify and document specific in-
    stances  where uncontrolled haz-
    ardous  waste sites have been
    cleaned up and redeveloped;
  2. assemble information on the
    criteria used to guide hazardous
    waste cleanups; and

-------
  3.  examine the relationships  be-
     tween site reuse and the extent of
     remediation or cleanup criteria.

Case Studies
  To serve as case studies to illustrate
contaminated land reclamation and de-
velopment,  16 sites located in  nine
states were selected  and examined in
detail. Case study sites included former
Department of Defense (DOD) proper-
ties, defunct coal gasification sites,
abandoned  chemical recovery and
drum recycling facilities, a former steel
mill, munitions, fertilizer, and pesticide
manufacturing sites, a coal tar refinery,
a warehouse for chemical storage, and
several uncontrolled dump sites. Land
reuses at these sites included industrial
parks, recreation parks, a hotel and con-
vention complex,  single family  resi-
dences, a public school, residential con-
dominiums, a  housing complex for
handicapped and elderly, a neighbor-
hood playground, and State offices and
facilities.
  Six of the land  reuse case studies
were located in California. Concerns at
these sites pertained mainly to potential
exposure of persons who might live or
work at the site following redevelop-
ment. In most cases, material and soil
that  was determined by the California
Department of Health Services  (CDHS)
to be hazardous was removed to a per-
mitted  disposal facility. All of the Cali-
fornia case studies were located near
large metropolitan  areas.
  In Hercules, California, the former site
of the  Hercules  Powder Works which
manufactured dynamite and other mu-
nitions from 1912 until 1963, three cases
of successful redevelopment were doc-
umented. A residential subdivision (sin-
gle family homes) with a public school
was developed as Bayside Village on
the southernmost portion of the former
Hercules  property following  a  very
stringent  remediation  effort in 1981.
Cleanup operations on a second tract of
the property were completed in 1983 by
Bio-Rad Laboratories, and an industrial
park is currently being developed there.
Another tract of  50 acres was also
cleaned up in 1983 to make way for the
residential condominiums known as
Hercules Village.
   Residential condominiums were also
developed at former uncontrolled haz-
ardous waste sites in  Huntington Beach
and Yorba Linda, California. Contamina-
tion at these sites stemmed from dump-
ing  of refinery wastes including both
acid and alkali sludges. The removal op-
erations at these sites were complicated
by extensive foul odors from sulfur
compounds released from the
petroleum waste during excavation. All
waste material and contaminated soil
were removed to a landfill permitted to
receive hazardous waste.
  In south San Francisco a former steel
mill and fabrication plant site was rede-
veloped as "The Gateway," a hotel and
convention center complex. The reme-
diation agreement stipulated that the lo-
cation of the contaminated soils be
clearly designated on a site map and
that these areas not be excavated or
substantially disturbed in  the future
without CDHS approval. A deed restric-
tion was negotiated as a way of enforc-
ing these provisions over time.
  The Dade  County Transit Authority
has plans for a maintenance facility at
the former Miami Drum Services site in
Miami, Florida. The contamination re-
sulting from  the drum recycling opera-
tion caused major concern because the
Biscayne Aquifer,  which  supplies the
drinking  water for Dade  County, lies
only  one meter  below  the  natural
ground surface at the site. Although
total metal concentrations  in  the soil
were used as guidance in the initial ex-
cavations,  final  excavations were
guided by the results of chemical tests,
together with engineering and scientific
judgment.
  The former Chemical Metals Indus-
tries, Inc. sites in Baltimore, Maryland,
also presented an immediate potential
hazard. In this case, the major concerns
included  imminent threat  of fire or ex-
plosion in the residential neighborhood
due to the chemical incompatibilities of
the materials present and  to the poten-
tial hazard posed  by runoff from the
site. Following a remedial action under
CERCLA,  the site now serves as a neigh-
borhood playground and as the location
of a State office building.
  In Winooski, Vermont, a warehouse
formerly  occupied by a silk-screening
firm and used for storing a variety of
chemicals has been renovated to pro-
vide housing for  elderly and handi-
capped persons. Remedial action at the
site involved removal of piles of  solid
chemical wastes that had  filtered
through cracks and holes in the wooden
flooring.
  Remediation and redevelopment at
the Kapkowski Road site in Newark,
New Jersey, are underway by the Port
Authority of  New York and New Jersey.
Pockets of PCB-laden oil are being elim-
inated through a series of oil recovery
wells. The site had been used for mai
years as a dump, receiving solid refu
and waste oil. The property is adjacen
to the Newark Airport, a prime location
for an industrial park. The extent of the
remediation to be performed will be de-
termined when excavation begins for
building. If, during construction, soils
are encountered that contain more than
5 ppm of PCBs, the contaminated mate-
rial will be removed to a permitted dis-
posal facility.
  A local Industrial Foundation in Glen-
wood, Iowa, is currently seeking a ten-
ant for a site formerly occupied by a
pesticide plant. An extensive cleanup at
the site was carried out following a fire
in 1979.
  At Pittsburgh, New York, a. recre-
ation park now occupies a site where a
coal gas generating plant operated from
1896 until 1960. Large quantities of coal
tars stored in unlined ponds resulted in
the contamination. The site remediation
consists of containment onsite and a
cement-bentonite partial cutoff wall to
arrest any further migration of the con-
tamination into the Saranac River. In al-
lowing the material to remain onsite,
the New York State Department of Envi-
ronmental Conservation (NYSDEC) has
imposed certain restrictions to develop-
ment.
  Two other  coal gasification sites lo-
cated in Seattle and Bellingham, Wash-
ington, are now used as recreation
parks. The extent of the remediation ef-
forts at these sites is not documented
because at the time of the redevelop-
ment, hazardous wastes were not of
much concern. Recent investigations at
both sites have revealed the presence of
high levels of polycyclic aromatic hy-
drocarbons from coal tar.
  Among  the U.S. Department of De-
fense (DOD) sites where  remediation
and  redevelopment have been under-
taken is the Frankford Arsenal site lo-
cated in eastern Philadelphia on the Del-
aware River.  For more than 150 years,
this  110 acre site was associated with
federal  munitions research,  develop-
ment, and production. When the U.S.
Army decided to excess the facility in
1976, the U.S. Army Toxic and  Haz-
ardous Materials Agency (USATHAMA)
assumed responsibility for the site
cleanup to satisfy the requirements of
the  General Services  Administration
prior to sale  of the property to private
developers. A large portion of the old
arsenal has been sold to a development
consortium and will be developed for
use  by multiple tenants for light indus-

-------
_try. The property closest to the water is
 intended  for use as a regional marina
 and park to be built by the Pennsylvania
 State  Fish Commission. Projected for
 completion in 1986, development of this
 18-acre facility is  expected to cost  $3
 million.
   The redevelopment of a former coal
 tar refinery site in Renton, Washington,
 is currently in the planning stage. The
 site has extensive contamination from
 slag and waste landfilled during the op-
 eration of the refinery which produced
 creosote and pitch for wood preserving.
 A private development consortium has
 proposed a remediation scheme which
 is considered by the Regional EPA offi-
 cials and  local authorities to be sound.
 The proposed remediation and redevel-
 opment plans have been delayed re-
 cently because the site was placed on
 the National Priorities List (NPL).

 Conclusions
  There are many  instances in the
 United States where uncontrolled haz-
 ardous waste sites have been  or soon
 will be redeveloped for some upgraded
 land use.  This trend is expected to in-
 crease as more sites are remediated.
 Sites that are redeveloped following
 hazardous waste cleanups are  not eas-
 ily documented through references  to
 the open literature, for several reasons.
 First, the brief history of federally sup-
 ported waste site remediation efforts in
 this country  has not  yet resulted in  a
 long list of completed projects.  Second,
 the substantial costs and investment
 risks associated with  hazardous waste
 site cleanup operations appear to have
 discouraged  developers from attempt-
 ing to reclaim many contaminated sites.
 Third, the delays associated with
 decision-making may stifle redevelop-
 ment projects where hazardous wastes
 are involved. When developers do be-
 come  involved with  an uncontrolled
 hazardous waste  site, they try to per-
 form the necessary remediation to the
 satisfaction of the regional and local au-
 thorities with little publicity, if possible.
  Uncontrolled waste site development
 projects appear to be of two distinctly
 different types. The first typ,  nay be
 termed the developer-initiated  ^devel-
 opment effort. Such  cases  of site
 cleanup and redevelopment occur  in
 large metropolitan regions and other
 areas where the locational advantages
 of a site alone are so great that cleanup
 costs can  be recovered through future
 resale  of  the remediated  property.  In
 such cases, the decision to remediate
and redevelop a specific site is made in
the private sector, and the public sector
simply regulates and certifies the
cleanup process. Such was the case for
several of the examples of site redevel-
opment case studies in California.
  The second type of hazardous waste
site redevelopment project is the public-
initiated project where reuse of the land
is clearly secondary  in importance to
the site remediation that is required for
public health and safety. This appears to
be the case, for example, with almost all
sites on the NPL. For most  public-
initiated cleanup  operations, remedia-
tion  activities are so complicated and
costly  that the economic value of  the
site following cleanup only partially jus-
tifies the cleanup operation, if at  all.
Where  a remediated  site passes into
public  ownership, reuse will probably
be determined by the specific property
needs of the governing body at that par-
ticular  location and time.
  It is important to note that these two
types of hazardous waste site redevel-
opments result from two entirely differ-
ent motivating forces. In the first case
(developer-initiated cleanups),  the  de-
veloper is simply responding  to land
market forces  and  diverting into
cleanup operations dollars that would
otherwise be used to purchase uncon-
taminated land.  In the second case
(public-initiated cleanups), the redevel-
opment decision is made in the public
sector, and there is no explicit require-
ment that cleanup costs be  recovered
through future uses of the property.
  Of the reuse sites  examined in this
study, few involved Super-fund monies.
The complexity of the legal process in
dealing with Superfund site cleanup is
not conducive to deliberate redevelop-
ment efforts. Even in cases where emer-
gency  remedial response actions have
been completed,  it appears that the site
may remain in receivership and go  un-
used for long periods of time (typically
several years) while the courts decide
cost  recovery and/or property owner-
ship  issues.
  A central issue for the planning of any
site redevelopment is the criteria to be
used in determining the extent of
cleanup that is to be  required. Accept-
able  concentration limits to establish
the extent of cleanup that is  necessary
to protect public health and welfare
have not been determined for  most
toxic substances of concern.
  Almost all states have problems deal-
ing with the "how-clean-is-clean?"
issue. Since  different uses may imply a
 need for different cleanup criteria, this
 type of judgment must be made on a
 case-by-case basis. Residential use  is
 generally felt to require the most strin-
 gent cleanup.
  In order to determine acceptable con-
 taminant levels in soils, two primary ex-
 posure routes are usually considered—
  1. inhalation of gases, vapors, or air-
     borne particulate emanating from
     the site; and
  2. ingestion  of contaminated drink-
     ing water.
 Other routes that can contribute to ex-
 posure include  absorption of pollutants
 through direct skin contact or uptake of
 water  or soil contaminants by plants
 and  subsequent ingestion by man.
  Recognized guidelines pertaining to
 acceptable pollutant levels include air
 quality standards, occupational expo-
 sure guidelines, drinking water stand-
 ards, and water quality criteria. Al-
 though developed for other purposes,
 these established sets of guidelines are
 frequently  relied upon  as  criteria for
 cleanup.
  Most states have not established  a
 systematic screening approach to iden-
 tify potential hazardous wastes sites in-
 cluding sites with potential for reuse. As
 a result, plans to develop an uncon-
 trolled hazardous waste site for a sensi-
 tive reuse could proceed without com-
 ing  to the attention  of  the State
 authorities. Most states  do  not have  a
 plan or formal  mechanism  for dealing
 with redevelopment of contaminated
 land. The only work that has been done
 in some states is the cleanup of spills or
 other emergency response action.
  California appears to lead other states
 in the formulation and enactment of leg-
 islation and regulations pertaining to
the cleanup and redevelopment of
 properties  contaminated  with haz-
ardous waste.  With adoption of the
CAM Standards, California has begun to
define  quantitatively what is meant by
 "hazardous waste contamination."
Their program  for guiding  redevelop-
 ment of contaminated land  appears to
be the most  advanced state program in
the Nation.
  There are many sites in  the  United
States that require remedial actions and
 reuse planning. The learning experi-
ences of developers and public agen-
cies addressing the issues arising from
contaminated land and  its  redevelop-
ment can benefit others who might be
involved in similar activities. Therefore,
an ongoing effort to assemble the type
of information  provided through this

-------
   study could serve as a valuable source
   of information  for federal, state, and
   local  authorities. Such information
   would also be of value to developers in
   the private sector who, having  more
   knowledge of successful redevelop-
   ment  projects as well as potential  pit-
   falls, might be more inclined to get in-
   volved in remedial actions.
