United States Environmental Protection Agency Hazardous Waste Engineering Research Laboratory Cincinnati OH 45268 Research and Development EPA/600/S2-86/066 Feb. 1987 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.
