Superfund: State Voluntary Programs Provide Incentives to Encourage Cleanups

Letter

Introduction

In 1980, the Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) to clean up hazardous waste sites. Since that time, the federal government has made some progress in cleaning up sites that have been labeled as the worst in the nation, and the states have identified and cleaned up additional hazardous waste sites. However, thousands more sites have not yet been addressed at either the federal or the state level. To manage these sites, states began to develop new voluntary cleanup programs that would leverage private funds to pay for cleanups and return the sites to productive use.

Federal and State Hazardous Waste Cleanup Policies

Under Superfund, the Environmental Protection Agency (EPA) has established a process for assessing hazardous waste sites, selecting appropriate techniques for cleaning them up, constructing cleanup methods or remedies, and maintaining the remedies. The law requires EPA to develop and maintain a list of hazardous sites it considers to be the most seriously contaminated, known as the National Priorities List (NPL). If EPA, a state, or any other party identifies a contaminated site, the site can be referred to EPA, which in turn includes it in the agency’s inventory of potential sites. Once in the inventory, the site is assessed to determine whether it is contaminated seriously enough to be placed on the NPL.

The law makes parties responsible for the contamination—including current and former site owners and site operators, waste generators, and waste transporters—liable for cleanup costs. The federal government may take action to compel a responsible party to perform or pay for a cleanup. Under Superfund, any party that contributed to the contamination, even if this action was legal at the time, is liable and under certain circumstances may be held responsible for the entire cost of the cleanup. EPA may also use the Superfund trust fund, supported primarily by a tax on crude oil and certain chemicals, to pay for the cleanup and then seek reimbursement from responsible parties. Under EPA’s regulations, the fund may be used to finance long-term cleanups only at sites on the NPL. EPA may also use the fund to take short-term actions that address contamination at any site posing an imminent and substantial threat to human health and the environment, regardless of whether the site is included on the NPL.

Over the past 16 years, the Congress has authorized a total of $15.2 billion to be appropriated from the Superfund. The NPL currently consists of about 1,300 sites. At the time of our review, remedies had been completed at 412 of these sites. EPA has also taken about 4,000 short-term cleanup actions. Approximately 70 percent of the cleanups at NPL sites are now funded by responsible parties, and EPA funds the remaining cleanups from the trust fund. EPA also has a list of about 12,000 sites in various stages of assessment to determine whether they meet NPL criteria, and it expects more sites to be identified and referred for its consideration.

Forty-one states have followed the federal government’s lead and established their own version of the Superfund law in order to identify and address sites not covered by the federal program. As a result, most states now have departments and staff dedicated to managing hazardous waste cleanups. The states generally address the thousands of sites that do not meet the risk criteria for placement on the NPL. In addition, a state may choose to forgo having EPA assess a site for placement on the NPL and, instead, handle it under the state’s cleanup program. Some states have adopted liability provisions similar to Superfund’s and have developed lists of sites in their state requiring cleanup. These states have relied primarily on enforcement actions against responsible parties to clean up sites, using state funds only to clean sites where responsible parties are recalcitrant or cannot be found.

After over a decade of federal and state efforts, significant numbers of sites remain to be cleaned up. Because of limited resources, EPA and the states have targeted their enforcement and cleanup efforts to the worst sites on their lists. Furthermore, cities, lenders, developers, and others with an interest in returning contaminated sites to productive use have been reluctant to begin cleanups on their own because, under Superfund’s or the state’s liability provisions, they could then be held liable for entire cleanups. In addition, they might later be held liable for further cleanup actions at the sites if new or more contamination were discovered or stricter environmental standards were established.

State and Federal Actions to Encourage Voluntary Cleanups

To encourage redevelopment and help clean up sites that have not yet been addressed, most states, in the last few years, have created voluntary cleanup programs. In contrast to the state cleanup programs that rely on enforcement to compel cleanups by responsible parties, these programs allow volunteers, such as site owners or developers, to approach the state and initiate cleanups on their own. As a result, volunteers can avoid the delays and costs associated with the enforcement process and conduct cleanups within the time frames needed for redevelopment or sale. Once a volunteer has completed a cleanup, a state typically certifies that the cleanup meets the state’s requirements and standards, giving the volunteer some assurance that the state is unlikely to require further cleanup in the future.

Voluntary programs were a natural outgrowth of property transfer laws that many states already had in place. These laws require property owners to disclose whether their property is contaminated with hazardous wastes, either by including this information in the deed or by notifying the potential purchaser directly. However, disclosing the existence of contamination sometimes prevented property sales because of the uncertainty surrounding the cost of cleanup. Voluntary cleanup programs provided owners or buyers with a method for assessing the existing contamination and cleaning it up on their own while affording some assurance that the state would be unlikely to impose additional cleanup requirements at a later date. This arrangement allowed property transactions to move forward.

Because voluntary programs are likely to produce more cleanups than the states can compel under their enforcement programs alone, the states can also benefit from these programs. However, sites with low development potential—such as those in areas with inadequate infrastructure, high taxes, crime, congestion, or other problems— are unlikely candidates for voluntary cleanups. The states will have to continue handling these types of sites, as well as any others they exclude from their voluntary programs, through traditional enforcement cleanup programs.

EPA saw state voluntary cleanup programs as a way to leverage the limited state and federal resources available for hazardous waste cleanups. The agency is currently drafting guidance for establishing agreements with states that would specify, for programs meeting EPA’s criteria, that generally EPA will plan to take further action at sites in a state’s voluntary program only in limited circumstances. By reducing the threat of federal Superfund liability, these agreements could increase potential volunteers’ interest in the programs. In addition, EPA has allowed states to use funds from their fiscal year 1995 and 1996 Superfund cooperative agreements with the agency to develop voluntary programs.

The Congress has also taken actions to encourage voluntary cleanups of hazardous waste sites. Lenders had feared being named as a responsible party if they foreclosed on a contaminated property. In 1996, the Congress passed legislation limiting lenders’ liability at contaminated sites. As a result, lenders may be more willing to finance projects to redevelop or clean up contaminated sites.

At the same time states began developing voluntary programs, the federal government’s interest in redeveloping brownfields began to grow. Brownfields are abandoned or underused facilities, usually in industrial or commercial areas, where redevelopment has been hampered by real or perceived environmental contamination. Voluntary cleanup programs are viewed as an important tool for facilitating the redevelopment of brownfields because they allow owners and developers to identify potentially valuable sites and clean them up independently. EPA took several initiatives to encourage the redevelopment of these sites. For example, the agency funded 78 pilot brownfields projects around the country to promote creativity in addressing these types of sites. In addition, to reduce the stigma of association with the Superfund program, EPA classified approximately 29,000 sites from its inventory of potential NPL sites as needing no further action. To focus national attention on brownfields, EPA convened a series of conferences about them and created an interagency working group to draft a coordinated federal brownfield policy.

Objectives, Scope, and Methodology

The Chairmen of the Senate Committee on Environment and Public Works and its Subcommittee on Superfund, Waste Control, and Risk Assessment asked us to review state voluntary cleanup programs. We agreed to (1) identify voluntary cleanup programs’ accomplishments; (2) describe these programs’ organization, funding, and major characteristics; and (3) determine the effects of federal hazardous waste policies on voluntary cleanups and the types of federal assistance that could further support voluntary programs.

To identify examples of voluntary cleanup programs’ accomplishments, we surveyed the administrators of 17 of these programs in 15 states, concentrating first on 5 well-established programs in the Midwest and then choosing additional programs in each of EPA’s regional offices to obtain geographic diversity and a mix of program models. These 15 states constitute over 40 percent of the 35 states that we found had created voluntary programs nationwide. The 15 states were California, Colorado, Delaware, Indiana, Illinois, Massachusetts, Minnesota, Missouri, New Jersey, Ohio, Pennsylvania, Tennessee, Texas, Washington, and Wisconsin. Massachusetts and Washington each administer two different voluntary cleanup programs, which we included in our research, for a total of 17 programs in 15 states. We conducted a telephone survey with the managers of the 17 programs and asked them for information on their program’s success in achieving cleanups. We also reviewed materials on the programs that they provided.

To evaluate these programs’ organization, funding, and major characteristics, we surveyed officials in the 17 programs and asked them to compare the procedural and cleanup requirements of their state’s voluntary cleanup program with those of their state’s enforcement program. We also interviewed national representatives of lenders; developers; and environmental, state, and community development organizations about their experiences with voluntary programs. We reviewed studies on voluntary cleanups conducted by other organizations.

To determine the effects of federal hazardous waste policies on voluntary cleanups and the types of federal assistance that could help the states develop effective voluntary cleanup programs, we reviewed EPA’s and the Congress’s efforts to support voluntary programs. We surveyed officials of the 17 voluntary programs to obtain their opinions on the current federal efforts and asked them whether the federal government could provide any additional assistance. We interviewed officials in 13 states that currently do not have a voluntary program about their plans for creating one. We also interviewed EPA headquarters officials and officials in four EPA regions for their views on EPA’s efforts to support voluntary cleanup programs.

We conducted our work from June 1996 through March 1997 in accordance with generally accepted government auditing standards.

Agency Comments

We obtained comments on a draft of this report from officials in EPA’s Office of Solid Waste Emergency Response, including the Director of Outreach and Special Projects Staff, the office responsible for EPA’s voluntary cleanup and brownfield initiatives. We also obtained comments from the Deputy Director of the State, Tribal, and Site Identification Center in the Office of Solid Waste and Emergency Response and from an official in EPA’s Office of Enforcement and Compliance Assurance. We responded to their comments throughout the report and summarized their views in the executive summary and in chapter 4. For each of the 17 voluntary programs that we reviewed, we provided state officials with the information we planned to report, asked them to verify its accuracy, and revised the information in response to their comments. Finally, we obtained comments on the draft report from a representative of the Association of State and Territorial Solid Waste Management Officials who has been involved in the organization’s task force on cleanup programs. In response to his comments, we made several changes to clarify portions of the report.

Voluntary Programs Allow More Sites to Be Cleaned Up Faster and at Less Cost

Through voluntary programs, thousands of sites are being cleaned up, including those that a state or EPA has identified as a problem and those that a volunteer has discovered. Without the voluntary programs, these cleanups would generally not have occurred because the federal and state enforcement programs have not had the resources to support them. Voluntary cleanups can be completed more quickly than cleanups under state enforcement programs, according to state officials, because the voluntary approach eliminates some of the cleanup and enforcement steps. For the same reasons, voluntary cleanups are also less costly for both the states and volunteers. As a result, voluntary cleanups are encouraging economic redevelopment, including that of former industrial sites known as brownfields, by expediting the sites’ return to productive use.

Volunteers Identify and Clean Up More Sites

All of the 17 voluntary programs we reviewed reported identifying and cleaning up significant numbers of sites. Officials for each program we reviewed said that their state’s voluntary program is addressing more potentially contaminated sites than their state’s enforcement program alone could have accomplished. (See fig 2.1.)

The number of completed cleanups varied from program to program, in part because of differences in the ages of the programs, the attractiveness of the incentives they offered, and the ability of the states to track cleanups (some programs do not learn about voluntary cleanups until after the cleanups have been completed). For example, at the time of our survey, four cleanups had been completed through Tennessee’s voluntary program, which is relatively new (1994) and offers fairly limited incentives, whereas 198 cleanups had been completed through Illinois’ 8-year-old program, which offers more incentives. New Jersey and Massachusetts, with the highest numbers of voluntary cleanups, have large staffs devoted to hazardous waste cleanups and long histories of administering these cleanups.

Voluntary programs address sites that the federal or state enforcement programs could not manage, given their existing cleanup workloads and resources. For example, according to an EPA study, the states in our review had identified about 54,000 sites that could be contaminated enough to merit cleanup under the states’ enforcement cleanup programs. EPA has approximately 12,000 sites that have been identified and await evaluation and approximately 1,300 evaluated sites that have been placed on the NPL and remain to be addressed. Since both the states and the federal government have limited program resources, they will not be able to address all of these sites at once. When volunteers clean up these sites, they free the government programs’ resources for other sites.

State officials attributed the success of their voluntary programs to the incentives these programs typically provide to attract participants, including (1) relief under state law from future liability—and therefore relief from the risk of incurring additional costs—for past contamination; (2) clearly defined cleanup standards that identify the extent of the necessary cleanup—and therefore the time and costs involved—at the start of a cleanup; and (3) reduced paperwork and cleanup requirements. These incentives allow volunteers to predict their costs and estimate their long-term responsibility for a site more accurately, improving their ability to weigh the costs and benefits of a cleanup and determine whether to make the investment.

Besides promoting cleanups, voluntary programs have encouraged owners to identify contaminated properties. Every state program official said that volunteers have identified and cleaned up hazardous waste sites that the state had not known of or had not listed as priorities for cleanup before the volunteers initiated the cleanups. Since owners can better assess the cleanup actions and costs they will face under voluntary cleanup programs, they are more willing to notify state officials of their contaminated sites and take action. Two voluntary cleanup programs have explicitly allowed volunteers to assess sites where contamination has been perceived, determine that no contamination is present, and certify the sites as clean if they meet the state’s cleanup standards and need no additional action. This certification helps to remove the stigma of association with hazardous waste at these sites and encourages owners and developers to enter them into the real estate market. Two states reported that such sites represent a substantial portion of the sites in their programs. According to the managers of the Illinois and Minnesota voluntary programs, about half of their completed sites fall into this category.

Voluntary Cleanups Cost Less and Take Less Time

Because voluntary programs have fewer paperwork and oversight requirements than enforcement programs, they cost less both for the state and for volunteers, according to officials in every program we reviewed. The states receive funding for their programs by charging volunteers to participate, so their programs are, to some extent, privately financed. Volunteers either pay a fee when they apply for the program or reimburse the state for its costs of overseeing the cleanup. The states also avoid the costs, incurred under enforcement programs, of investigating sites, identifying responsible parties, legally compelling these parties to perform cleanups, and trying to recover their costs. All of the state program officials said that cleanup costs were lower for volunteers than for parties compelled to clean up a site through an enforcement program, although the managers could not quantify the savings. Volunteers avoid the legal costs of responding to an enforcement action and can scale back or eliminate some cleanup steps, according to these officials.

The less adversarial, more streamlined voluntary process also leads to faster cleanups, according to cleanup managers of the voluntary programs we reviewed. For example, according to Texas cleanup managers, a voluntary cleanup is typically completed within 1 year of a site’s entering the program. Massachusetts’ programs provide specific incentives for volunteers to complete a cleanup within 1 year of discovering contamination. Cleanups are also completed faster because 11 of the 17 voluntary programs set deadlines for reviewing and approving volunteers’ plans and cleanup activities. For example, program officials must often approve a site’s cleanup plan within 30 to 60 days of the plan’s submission. As a result, some states have given very high priority to their voluntary program. Officials in Delaware, Washington, and Wisconsin said that they sometimes give higher priority to overseeing voluntary cleanups than to overseeing state-initiated cleanups because their voluntary programs have shorter time requirements and the volunteers are paying for the oversight.

Voluntary Cleanups Lead to Property Redevelopment

Officials in all 17 voluntary programs we reviewed said that their program has restored some unused or underused sites to productive use. Since the cleanups are self-initiated, volunteers can identify potentially valuable pieces of contaminated property for cleanup and target them for redevelopment. The reduced costs and time for cleanup are making the voluntary cleanup and redevelopment of some contaminated sites a viable investment option. Most of these voluntary programs also limit a volunteer’s future liability under state law for a site’s contamination once the site has been cleaned according to the program’s requirements, reducing the risk that the volunteer will face future cleanup costs.

These incentives to clean up and redevelop sites are especially important for brownfields, the former industrial properties whose redevelopment is hampered by contamination. Several of the voluntary programs we reviewed provided incentives targeted specifically to these sites. Without voluntary programs that set out a method for evaluating and cleaning up these sites, developers may find it easier and cheaper to locate on “greenfields”—undeveloped property in suburban or outlying areas. By redeveloping brownfields, cities and states hope to boost employment and tax revenue in central urban districts and reduce suburban sprawl.

Voluntary program managers reported that new businesses have located on some of the brownfield sites addressed through voluntary programs. Examples of successful redevelopment projects include the following:

Chicago’s brownfield program cleaned up a closed wire-manufacturing facility in cooperation with the Illinois voluntary cleanup program. The site contained underground tanks and vaults filled with solvents and fuel oil that had to be removed. The city then sold the property to an adjacent fuel pump manufacturer, Blackstone Manufacturing. Blackstone built a secured parking lot on the site, allowing the business to add an extra shift of workers and increase production.

The Cellular One Corporation cleaned up several adjacent lots in New Berlin, Wisconsin, through the Wisconsin Land Recycling Program. The lots had been used for a variety of businesses, including those that repaired, maintained, and stored heavy vehicles. The site had a history of chemical spills, and the ground was contaminated with waste oil sludge, underground and aboveground storage tanks, and miscellaneous debris. Now that the soil has been excavated and treated and the tanks and debris removed, Cellular One plans to build a warehouse and office building on the site.

Occidental Chemical Corporation operated a facility in Clarksville, Indiana, from 1950 to 1992. The facility, which manufactured laundry detergents, produced sodium and potassium phosphate products and phosphoric acid. The facility’s cleanup was conducted under the Indiana voluntary cleanup program and consisted of demolishing all existing structures and removing over 25,000 cubic yards of soil contaminated with arsenic and phosphorus. Occidental then sold the 26-acre property to a real estate developer after receiving a covenant-not-to-sue from Indiana. A retail developer bought the site and constructed a large retail shopping center.

Thonet Manufacturing produced furniture in York, Pennsylvania, until the facility burned in 1993. A volunteer cleaned the property under Pennsylvania’s cleanup program, removing debris from the fire, paint containers and other drums, soil contaminated with lead and benzene, and asbestos. The groundwater was also contaminated and had to be cleaned to standards for industrial use. The volunteer is now building a 37,000-square-foot facility to manufacture countertops.

Voluntary Cleanup Programs Differed Significantly From One Another and From Enforcement Programs

Our review of 17 voluntary programs in 15 states showed considerable variation in their organization and incentives to attract participants. For example, some states established independent voluntary programs, while others combined their voluntary and enforcement programs or relied solely on a voluntary approach to cleanup. While all voluntary programs collected fees from participants to fund their voluntary activities, most programs also used some state support. Although nearly all of the voluntary programs relied on incentives—rather than enforcement—to encourage the transfer and economic redevelopment of potentially contaminated properties, these incentives differed from program to program. Whereas nearly all of the voluntary programs admitted sites contaminated enough to qualify for federal cleanup, two programs managed such sites only through the federal or their state’s enforcement program. A few voluntary programs were more willing than others to release participants from further liability for contamination after completing cleanups. All of the 17 programs reduced the requirements they imposed on cleanups to attract participants, but the changes varied extensively. Some programs significantly reduced the requirements for monitoring nonpermanent cleanups, overseeing cleanups, and involving the public in cleanup decisions, while other programs varied the requirements they placed on cleanups with the risks and conditions at individual sites.

Voluntary Cleanup Programs Differed in Their Organization and Funding

Most of the voluntary cleanup programs we reviewed were relatively new and differed significantly from one another in their organization, staffing, and sources of funding. When we conducted our review, 35 states had developed voluntary cleanup programs. All of these programs have been established in the last 9 years. State legislatures established 31 of these programs by statute, and state environmental agencies created the other 4 through regulation. Ten of these programs have negotiated agreements with EPA which state that the agency will generally not plan to take further action at sites involved in the program except in limited circumstances. Figure 1 shows the status of voluntary cleanup programs throughout the nation at the time of our review.

Most of the voluntary cleanup programs we reviewed were administered either as part of a state’s Superfund program or as an alternative to it. Ten of the 17 programs were managed by the same staff who managed the enforcement program, 5 were managed by separate staff, and 2 had almost or fully taken the place of the enforcement program. Pennsylvania relied on its voluntary cleanup program for most of its cleanups, and Colorado had no enforcement program—all nonfederal cleanups in the state were voluntary.

All of the voluntary programs we reviewed charged volunteers a fee to help cover the costs of administering the program and overseeing the cleanups; however, the amount and type of the fee varied. For example, some of the programs charged volunteers a fee to apply for participation. This fee, which ranged from $200 to $5,000, covered the states’ oversight costs to varying degrees. Other state programs billed volunteers directly to cover their oversight costs for such activities as reviewing the reports that volunteers submit and visiting the sites. (See table 3.1.)

Not all of the programs we reviewed charged volunteers enough to fully finance their program and had to cover some costs from their general revenues, hazardous waste cleanup funds, and/or federal Superfund cooperative agreement funds. Colorado’s program, for example, can charge a fee of up to $2,000, but this amount may not suffice to cover the costs of overseeing some cleanups. When the fee is insufficient for a Colorado site, the state and the volunteer agree to divide the site into parts, and the volunteer pays an application fee for each part. In Ohio, the program borrowed from the state’s general fund to pay its start-up costs. Low initial participation has since precluded the program from paying for itself or paying back the loan. In contrast, Minnesota’s program charges $75 to $90 per hour for oversight, depending on the salary levels of the staff assigned to the project and an overhead factor. This approach allows the agency to recoup all of its operating costs, including those for oversight and overhead, directly from the volunteer.

Voluntary Cleanup Programs Offered Different Incentives to Participants

For most of the voluntary cleanup programs we reviewed, the main objectives are to encourage and facilitate the transfer and economic redevelopment of contaminated property through environmental cleanup. In contrast to enforcement programs, which legally compel parties to clean up contaminated sites, these programs use incentives to attract volunteers to perform cleanups. Compared to enforcement programs, most voluntary programs have fewer administrative requirements to meet during the cleanup process and give volunteers more control over cleanup decisions. However, the voluntary programs differed, for example, in the types of sites and in the types of volunteers they allowed to participate in their programs. They also differed in the extent to which they released volunteers from future liability for past contamination and in the stringency of their requirements for monitoring, oversight, and public participation. (See app. I for a listing of each program’s components.)

Participation Varied for Highly Contaminated Sites and for Parties That Caused the Contamination

All but two of the voluntary programs we reviewed prohibited the enrollment of sites that were already involved in the federal Superfund program. Most of the programs also prohibited the enrollment of sites involved in their state’s enforcement program. However, the managers for 15 of the 17 programs reported that their program would admit sites that could be contaminated enough to qualify for federal cleanup but had not been referred to the Superfund program. Several of these managers expressed their willingness to rely on volunteers who are ready and able to clean up such sites as a means of returning the sites to productive use. The other two programs would not admit such sites because, according to their managers, sites with this level of contamination are more appropriately addressed under a state or federal enforcement program. Three of the 15 programs that admitted sites contaminated enough to qualify for federal cleanup restricted participation in their voluntary program to sites that do not pose an immediate risk to human health or the environment. (See table 3.2.)

Several states allowed sites needing cleanups normally regulated under a federal law other than Superfund to participate in their voluntary program. The programs in Texas, Washington, and Wisconsin also allowed the participation of some sites that require the type of cleanup required by the corrective action provisions of the Resource Conservation and Recovery Act (RCRA)., The managers of most of the other programs said they would admit such sites only on a case-by-case basis. For example, the managers of Indiana’s voluntary program explained that they would enroll RCRA sites if the managers of the state’s RCRA program agreed that the sites’ enrollment would be appropriate.

Although most program managers reported that, to date, few sites contaminated enough to qualify for federal cleanup had applied to their voluntary program, several factors could increase participation by these sites as the voluntary programs mature. First, EPA has been adding fewer sites to the federal Superfund program. Second, EPA recently issued a policy stating its intent to consult with a state’s governor and environmental agency officials before including a site on the NPL, even though a 1996 legislative requirement to obtain the governor’s concurrence has expired. In addition, as we reported in March 1996, some states still have undiscovered sites and significant numbers of sites awaiting assessment to determine the extent of their contamination. For example, a cleanup manager in Illinois reported that environmental officials were still identifying sites that were contaminated enough to qualify for the federal cleanup program.

Besides restricting the types of sites allowed to participate, some voluntary programs restricted the types of participants. These programs cited the principle that the polluter should pay for the cleanup and not reap certain benefits of voluntary programs, such as significant releases from liability. For example, Delaware and Wisconsin provide less comprehensive releases from liability for responsible parties than for parties that did not contribute to contamination. Officials in programs that did not restrict participation explained that they view cleaning up and redeveloping sites rather than letting them remain idle as more important than delaying cleanups by pursuing time-consuming legal actions to assign responsibility for the contamination.

Most Voluntary Programs Offered Volunteers a Release From State Liability, but the Strength of the Release Varied

A release from further liability for previous contamination at a site is a major incentive provided by most of the voluntary programs we reviewed, but the extent of the release varies significantly. When a volunteer follows a voluntary program’s requirements, the program certifies that the cleanup is complete. This state certification provides the volunteer with some assurance that the site will not require any further action—or costs—to alleviate past contamination at the site. The assurance is designed to encourage cleanups and stimulate redevelopment by relieving participants of fears about the extent of the liability and cleanup costs they could face.

Of the 17 voluntary programs we reviewed, 11 used only one of three main approaches for certifying cleanups, 5 used more than one approach, and 1 used a different approach. The first type of assurance, a covenant-not-to-sue, was used by four of the programs. This covenant, offered to some or all volunteers, provides that the state will generally not take any enforcement action against the volunteer once a cleanup has been completed.

The second type of assurance, a certificate of completion, was offered by seven of the programs. According to this certificate, the cleanup has been completed in accordance with the program’s standards and rules. Most—but not all—of these programs included language in the certificate releasing the volunteer from further liability for past contamination.

The third approach, a no-further-action letter, was used by 11 programs. The letter certifies, on the basis of the state’s review of information from the volunteer, that the state does not expect to require further action of the volunteer. The letter does not, in most cases, excuse the volunteer from further liability. Table 3 sets forth the types of cleanup certifications offered by the voluntary cleanup programs we reviewed.

Some Voluntary Programs Provide Financial Incentives

Nine of the 17 voluntary programs we reviewed offered participants financial incentives to clean up sites, mainly as a means to encourage the industrial or commercial redevelopment of brownfields. These programs tended to focus the incentives on the sites that were the least attractive to prospective purchasers and developers. (See table 3.4.)

Of the nine programs offering financial incentives, most offered several types. For example, five programs allowed volunteers to use grant funds to subsidize the costs of site assessments or cleanups. Four programs also offered low-cost loans for these purposes in some cases. Four programs provided tax incentives for voluntary cleanups, including tax abatements or tax credits, and targeted these incentives to specific localities and activities. Two programs made tax increment financing available specifically for voluntary cleanups that resulted in redevelopment in certain localities.

Eight programs did not offer financial incentives at this time. Some of the state representatives we contacted were wary of providing such incentives because they did not want polluters to take advantage of them. The representatives pointed out that rewarding some polluters financially did not seem appropriate when other polluters had paid for cleanups through either enforcement or voluntary programs.

Voluntary Programs Offer Flexibility in Cleanup Levels and Methods

To attract participants, the voluntary cleanup programs we reviewed gave volunteers the flexibility to choose appropriate levels and methods of cleanup, some of which were less costly than those required by the enforcement program. However, the extent of the flexibility given to participants varied from program to program.

Volunteers Can Choose Cleanup Levels

The 17 voluntary programs we reviewed set requirements for the amount of risk reduction that cleanups must achieve in order to be protective of human health and the environment. Participants in these programs generally must meet the requirements by selecting one of three approaches for achieving an appropriate level of cleanup: the amount of a chemical that naturally existed in the local soil and groundwater before the contamination occurred; the cleanup standard established by the state for a contaminant, based on a determination of the maximum amount of the contaminant that can remain in soil or water without posing a risk to public health or the environment: The state analyzes the toxicity of the contaminant and the likelihood that people will be exposed to it to establish this cleanup standard; or the amount of cleanup necessary to control the unique risks posed by a particular contaminant at a particular site, as determined by a formal assessment of that site’s risks. This cleanup level may differ from site to site.

Officials from several voluntary programs told us that volunteers often select the second approach, cleaning up a site to the state’s established standards. While the first approach sometimes requires the volunteer to restore the site to “pristine” levels and the third approach is uncertain and sometimes costly, the second approach enables the volunteer, at the outset, to estimate the extent and the cost of the cleanup.

Both the second and third approaches also allow volunteers to link the cleanup standard to the use planned for the site. The standards are less stringent and less expensive to meet if the land will be used for industrial rather than residential purposes because people’s exposure to the site’s contamination will be more limited. The standards for industrial use are often appropriate because many sites are redeveloped for commercial or industrial purposes. Traditionally, the sites cleaned up under the federal Superfund program more often had to meet the most stringent standard for residential land use. In our review, we found that volunteers in 10 of the 17 programs used industrial standards most frequently for their cleanups. (See table 3.5.)

After selecting a level of cleanup, a volunteer must select a method of cleanup. The federal Superfund program establishes a preference for methods that result in a site’s permanent cleanup. Voluntary programs have not always adopted this preference for permanence, giving volunteers less expensive options to encourage their participation. A permanent remedy either removes or treats contamination in order to meet the applicable cleanup standards. A nonpermanent remedy typically prevents human contact with contamination by containing the waste—by, for example, placing a clay cap or a parking lot over contaminated soil, restricting the land’s use, or placing barriers around the contamination. Permanent remedies tend to be more expensive to implement than nonpermanent ones. The cleanup managers for 8 of the 17 programs we reviewed estimated that nonpermanent methods were used for at least half of their voluntary cleanups of contaminated soil. (See table 3.6.)

Some voluntary programs do not require the cleanup of contaminated groundwater. For example, to attract volunteers, some programs grant an exemption from their groundwater cleanup requirements if a volunteer can demonstrate that the waste at a site is not causing the contamination.Because groundwater cleanups are usually expensive and time-consuming, this exemption is an important incentive. It allows volunteers to control cleanup costs and increases the likelihood that investing in a site’s redevelopment will prove to be cost-effective.

Some voluntary programs also allow partial soil cleanups. For example, New Jersey’s program allows a volunteer to evaluate a site and clean up only the portion of a property that is to be redeveloped and to leave the remainder of the property untreated. In Illinois, a volunteer may decide to clean up just one of several chemicals at a site and receive a certification for that chemical alone. At a Superfund or state enforcement site, the cleanup would typically address all of the chemicals that threaten human health or the environment.

Programs Vary in Providing for Monitoring the Effectiveness of Less Permanent Cleanups

As we reported in 1995, the types of nonpermanent remedies used in many voluntary cleanup programs need ongoing monitoring and maintenance after the remedies have been implemented to ensure that they remain effective. Such activities can include mowing, inspecting, and repairing a clay cap; periodically sampling groundwater to ensure that chemicals are not leaching into it from the soil or migrating off-site; and inspecting and repairing signs and fences. Also, nonpermanent remedies premised on the restricted use of the land need a method to guarantee that the restrictions are maintained. The voluntary programs we reviewed varied considerably in their requirements for monitoring a site after its cleanup has been approved. (See app. II for a description of each state’s monitoring requirements.) As table 3.7 shows, 2 programs required extensive monitoring, 5 programs required no monitoring, and 10 programs required some monitoring.

Two of the programs we reviewed monitored cleanups at voluntary sites on a regular basis. Every 5 years, the voluntary program in California and the ordered site program in Washington review sites where follow-on operations and maintenance are necessary or land use is restricted. This approach parallels the Superfund program’s requirement that EPA conduct 5-year reviews of similar cleanups. Officials in these states said they would not feel comfortable releasing volunteers from liability unless the volunteers performed some monitoring.

Five programs did not provide for active monitoring by state officials after cleanup, even though most of these programs reported that volunteers used either industrial cleanup standards or nonpermanent cleanup methods for at least half of their sites. The program managers cited trade-offs between limiting volunteers’ choices of remedies and monitoring the remedies closely, on the one hand, and achieving high levels of participation, on the other. The Illinois official we spoke with partly attributed the significant numbers of participants in the state’s voluntary program to the availability of alternative remedies and limited monitoring requirements. According to the managers, the large number of cleanups accomplished through their voluntary programs preclude monitoring every site.

Instead of monitoring these sites themselves, the five voluntary programs generally relied on the private real estate market to enforce maintenance and land-use restrictions. When these programs certified a cleanup’s completion or released a volunteer from future state liability, they generally stipulated in the certification that it would be revoked if the land’s use changed or the cleanup method were not maintained. The program managers consider this stipulation sufficient to guarantee compliance because it would be discovered during the investigation preceding a site’s sale. They argue that if a volunteer does not comply, purchasers and developers will not choose the site for fear that the cleanup certification will be revoked and they will face liability for further action at the site.

The remaining 10 programs have tried to strike a balance between fairly rigorous and no requirements for monitoring after cleanup. Although these programs do not perform on-site reviews, they do require volunteers to periodically file reports on the conditions at sites with nonpermanent remedies. Compliance with these requirements is generally a condition of retaining the state’s limits on the volunteer’s future liability. For example, the Ohio voluntary program implements an operations and maintenance agreement with the volunteer that requires reporting in exchange for a state covenant not to sue the volunteer for past contamination at a completed site.

Programs Provided for a Range of Cleanup Oversight

To speed cleanups and attract participants, most voluntary programs require less oversight than enforcement programs. Both the federal and state governments typically oversee their enforcement program’s cleanups by requiring parties to submit their workplans and progress reports for review or by independently sampling and visiting sites. These procedures provide the enforcement agencies with important information on the quality and adequacy of the cleanups. In comparison, the amount of oversight for voluntary cleanups provided by the programs we reviewed ranged from extensive to minimal. (See app. III for a description of each state’s oversight requirements.) A few program managers in our survey reported providing substantially less oversight for their voluntary cleanups than for their enforcement cleanups. In contrast, several programs based their level of oversight on the characteristics of a site or reduced their oversight at certain stages of a cleanup when it was not critical to ensuring the cleanup’s effectiveness.

As table 3.8 indicates, five of the voluntary programs we reviewed provided for extensive oversight of voluntary cleanups, three programs required little oversight, and nine programs varied the level of oversight with the sites’ hazards or stage in the cleanup process.

The five voluntary programs that provide for extensive oversight of cleanups generally apply essentially the same requirements as their state applies to enforcement cleanups. These voluntary programs typically require participants to submit status reports at each stage of the cleanup—when assessing the nature of the site’s contamination, preparing a cleanup plan, and documenting the final cleanup. Officials from these states’ programs usually visit a site during a cleanup to determine whether the volunteer is completing the work according to the workplan. When the cleanup is complete, they may verify the volunteer’s final report by inspecting the site or by analyzing soil or water samples that they have taken to ensure that the cleanup meets the agreed-upon standards. According to one program manager in a state that releases volunteers from future liability, this level of oversight is important because the state may inherit responsibility for the site if the cleanup later proves to be inadequate. Oversight is also necessary because volunteers want to keep their costs as low as possible and the state needs to ensure that cost-cutting measures do not jeopardize the quality of the cleanup.

At the other end of the spectrum, three of the voluntary cleanup programs we reviewed—the Colorado, Pennsylvania, and Washington IRAP programs—provide little oversight for some or all of their cleanups, even though some of these programs admit sites that could meet the criteria for federal cleanup. For the majority of their sites, these three programs require few reports, seldom require site visits, and do not require verification of a volunteer’s final cleanup report through a site visit or other means. The Washington IRAP program, for example, which has approved 225 voluntary cleanups, allows a volunteer to clean up a site without obtaining the state’s approval or agreement. The program does not oversee the cleanup, but instead reviews the volunteer’s final report to determine whether the cleanup meets the state’s standards. Similarly, for the majority of Pennsylvania’s voluntary sites that use state-established or background cleanup standards, the volunteer is required to submit a final report upon completing a cleanup. A volunteer demonstrating compliance with applicable cleanup standards is relieved of further liability under state law for the contamination addressed by the cleanup and may not be sued either by citizens or by other parties connected with the site’s contamination. All of the voluntary programs requiring little oversight also limit the time available for oversight by providing for the automatic approval of reports that have not been reviewed on time.

According to the managers of these three programs, limiting oversight to attract participants is necessary and appropriate because voluntary cleanups usually address less contaminated sites than enforcement cleanups. Limiting oversight is further appropriate, managers in Colorado and Pennsylvania said, because voluntary programs are cooperative in nature. Volunteers want the certificate of completion and the release from liability that the state offers so they can use their properties; therefore, according to these managers, they are likely to do good work and provide the state with reliable information. Moreover, in the Pennsylvania program, for example, the liability release can be reopened if new contamination is discovered. As a result, the quality of the information provided by the volunteer is critical. The Colorado program manager also maintained that site visits would be too costly.

Nine of the voluntary programs have taken a variable approach to oversight that, they maintain, provides them with good information about cleanups without deterring participation. These programs have either reduced their oversight at certain stages or concentrated on more hazardous sites. They require volunteers to submit reports throughout the cleanup process but generally perform fewer site visits than the programs that provide for more extensive oversight. Some volunteers want the additional assurance of a cleanup’s adequacy that a site visit provides. New Jersey provides less oversight for small, less complex soil cleanups and more oversight for complex soil and groundwater cleanups and for longer cleanups. Minnesota bases the number of site visits on the severity of the contamination and the level of cooperation with the volunteer. Seven of these nine voluntary programs approve the final cleanup report submitted by the volunteer but do not independently verify the data because, as two managers explained, they believe the frequent reporting throughout the cleanup process has given them ample information about the quality of the cleanup. Tennessee, on the other hand, varies the number of reports it requires with the conditions at a site, but takes split samples at all sites, either during the cleanup or afterward, to verify the final report.

One-Half of the Programs Limit Opportunities for Public Participation

The voluntary programs we reviewed varied in their requirements for public participation, from those that always required formal public comments to those that made no provision for informing the public about the cleanup. (See app. IV for a description of each program’s public participation requirements.) In contrast, the Superfund program requires anyone conducting a long-term cleanup to give the public an opportunity to comment on the proposed cleanup plan. Public participation is required to assure an affected community that the planned cleanup actions will adequately address the risks that a site poses to public health and the environment. According to one observer and representatives of environmental groups, public participation can be especially important for sites with nonpermanent remedies because the public can help to identify the safeguards that will help keep people away from the contamination. Representatives from community action organizations pointed out that public participation is particularly important for voluntary programs when other checks and balances on cleanups, such as monitoring and oversight, have been reduced.

As table 3.9 indicates, three of the voluntary programs we surveyed always required public participation, eight required little or no participation, and the remaining five varied their requirements with the conditions at individual sites.

Three programs always require volunteers to consider how best to inform and involve the public in cleanup issues. The Indiana and Washington ordered site programs, much like the Superfund program, require volunteers to obtain and respond to public comments on cleanup plans. Volunteers may also be required to hold public meetings. In California, volunteers must prepare a community profile and work with state officials to determine appropriate avenues for public participation based on that profile and the site’s projected activities.

In contrast, eight programs require little public participation. Five require none, and three require only the publication in a local newspaper of a notice about the cleanup. However, as we noted in a 1994 report, newspaper notices are ineffective because community members do not always see them. Nevertheless, according to the managers of these voluntary cleanup programs and volunteers, the programs’ requirements for public participation are sufficient because most of the enrolled sites are only lightly contaminated and are located in industrial neighborhoods. These program managers do not view the Superfund model for public participation as appropriate for voluntary cleanup programs. They maintain that requiring extensive public participation would be counterproductive, adding unnecessary time and costs to cleanups and discouraging volunteers. Program managers in Illinois and New Jersey point out that arranging public meetings and obtaining public comments is very time-consuming. Moreover, according to one state official, the owners of contaminated sites are often anxious to rid themselves of the environmental liability associated with their site and do not wish to publicize its hazards. Finally, other officials explained that a volunteer planning to redevelop a site will have to obtain the approval of local officials, who are responsible for and answer to their constituents.

The six remaining voluntary programs agree that extensive public participation may not be necessary at every site and have tailored their public participation requirements to site-specific conditions. As discussed, several of these voluntary programs admit sites that are contaminated enough to qualify for the federal Superfund program and its more extensive public participation requirements. Texas requires a volunteer to notify neighboring property owners if the contamination at a site is found to exceed the state’s cleanup standards or if contamination could migrate from the site. Missouri requires the volunteer to hold a public hearing if the state plans to provide a covenant-not-to-sue. The Massachusetts and Tennessee programs require public meetings only if local officials or the public request them. Wisconsin’s requirements depend on a site’s risks and the public’s concerns; in some instances, holding public meetings or creating a local mailing list may be required to involve the public.

EPA Has Provided Financial Assistance to Voluntary Programs and Is Beginning to Clarify Its Role at Voluntary Sites

Because the current Superfund law gives EPA the authority to take cleanup or enforcement action at any hazardous waste site to protect human health or the environment, the states want to be able to assure their volunteers that EPA is unlikely to take future action at voluntary cleanup sites. At the same time, EPA has an interest in determining that the states’ programs are effective and protective before providing such assurance.

Recognizing these interests and the voluntary programs’ contributions to the cleanup of the nation’s hazardous waste sites, EPA has, since 1995, supported these programs. Both the agency and the Congress have supported the states’ efforts with funding for voluntary programs. Most of the states we surveyed found this federal assistance useful and wanted it to continue. To address volunteers’ concerns about federal liability for contamination at sites, a Superfund reauthorization bill recently introduced in the Senate would exempt from federal liability parties who are associated with a release of hazardous substances that is subject to a state’s cleanup plan. However, because the current Superfund law provides no such exemption from federal liability, EPA has outlined six elements in a memorandum to its regions that the states’ voluntary programs should include to receive the agency’s agreement not to plan to take federal enforcement action except in limited circumstances. These criteria, however, are very general, limiting EPA’s ability to ensure that these programs are protective of human health and the environment. The memorandum does not define the elements a voluntary program would need or the approaches EPA would accept in order for the program to qualify for an agreement with EPA.

EPA Retains Some Authority for Sites Cleaned Up Under States’ Voluntary Programs

Under the Superfund law, EPA has the authority, in certain circumstances, to take action at any hazardous waste site, including one being cleaned up outside the federal program. Specifically, the agency has the authority to (1) address any release or threatened release of hazardous substances that may endanger public health or welfare or the environment and (2) take enforcement action to ensure this protection.

Because EPA retains this responsibility, purchasers and real estate developers are sometimes reluctant to voluntarily clean up and redevelop sites because they fear EPA may require them to perform additional cleanup work in the future. Most states and volunteers are therefore interested in having EPA clarify the circumstances under which it would be likely to use its authority. For its part, EPA believes that it needs to determine that a state’s program is resulting in adequate cleanups before it agrees that it will not plan to take action at sites addressed by volunteers. Otherwise, if a remedy fails at a site cleaned up under a state’s voluntary program and the volunteer has been granted a release from state liability, EPA may have to address the problem itself or compel the responsible parties to do so. EPA is particularly concerned about quality and liability in connection with voluntary cleanups at sites that were contaminated enough to have qualified for the federal cleanup program.

States Encourage Federal Support for Their Voluntary Cleanup Programs

Because EPA and the Congress view voluntary cleanup programs as a way to increase the number of hazardous waste cleanups nationwide, they have supported the development of such programs. EPA has provided funds for the states to develop their programs and assess the sites enrolled in them. The Congress has also set aside funding for these programs. In addition, EPA is developing guidance to clarify its role at sites cleaned up through state voluntary programs. Most of the states we surveyed would like EPA and the Congress to continue this support.

EPA and the Congress Have Provided Funds

Since 1995, EPA has allowed the states to use a portion of the funds from their Superfund cooperative agreements to develop their voluntary cleanup programs. These agreements, which EPA has negotiated with the states since the beginning of the Superfund program, provide funds for the states to develop their Superfund programs, manage Superfund activities, and assess hazardous waste sites to determine their eligibility for the federal cleanup program. Cleanup managers for 15 of the 17 programs we reviewed said that EPA’s making some of this funding available for voluntary programs was helpful. For example, two managers explained that the funds were used for start-up costs, such as those incurred in hiring personnel, developing materials, or publicizing the program. Officials whom we surveyed in the states without voluntary programs also thought that such funds would help them initiate programs.

EPA has also allowed the states to use federal funds to assess brownfield sites. In fiscal year 1995, EPA began allowing the states to use funds from their Superfund cooperative agreements to assess brownfield sites.

The Congress has also provided funding for these programs. The House Conference Committee report accompanying EPA’s fiscal year 1997 appropriations act noted that the agency’s Superfund appropriation included $36.7 million for brownfield activities. EPA plans to use $10 million of these funds to develop and enhance states’ voluntary cleanup programs. Recently introduced legislation to reauthorize Superfund, the Superfund Cleanup Acceleration Act of 1997, would also provide annual grants to qualifying voluntary cleanup programs. The bill establishes criteria that require qualifying programs to provide (1) technical assistance to volunteers; (2) adequate opportunities for public participation; (3) streamlined cleanup procedures; (4) oversight and enforcement authorities adequate to ensure that voluntary cleanups will protect human health and the environment and that cleanups will be completed if volunteers do not finish them; (5) procedures for official approval of voluntary cleanup plans; and (6) official certification that cleanups are complete.

Most of the states we surveyed—even those with fees sufficient to cover the costs of their programs—identified ways in which they could use this support. Some states said the funds would help municipalities cover the costs of assessing sites where no parties had been identified as responsible for the contamination or where the cleanup costs would otherwise be too high to attract volunteers. One state was interested in using the federal grants to develop revolving loan funds to help municipalities clean up these types of sites. Others said they would use the funds to support their programs by, for example, publicizing the programs or developing better information systems to improve the programs’ management and evaluation.

EPA Is Developing Guidance for the States’ Programs

Although the recent Superfund reauthorization proposal would exempt releases of contamination subject to a state’s cleanup plans from federal liability, under the current law EPA retains the authority to clean up or order the cleanup of any release that threatens human health or the environment. As a result, in fiscal year 1995, EPA began developing guidance to clarify the role it expects to have at sites in states that have met its requirements for a voluntary cleanup program. Regions I, III, V, VI, VII, and VIII negotiated agreements with 10 states—Colorado, Illinois, Indiana, Maryland, Michigan, Minnesota, Missouri, Rhode Island, Texas, and Wisconsin. These agreements specify that EPA generally will not plan to take further action at sites in a state’s voluntary program except in limited circumstances, such as a new release of contamination from a site. Other states could also obtain an agreement if their EPA region determined that their voluntary program was adequate to protect human health and the environment. According to EPA officials, the 10 states find that the agreements are an efficient means of encouraging participation because they allay volunteers’ concerns about facing additional federal liability at a site in the future. Officials in many of the voluntary programs we reviewed that did not have an agreement also said that one would be useful for their state.

Because more states wanted an agreement, EPA used the initial agreements as models and in November 1996 issued an interim memorandum that its regional offices could use to develop other agreements. EPA is working with the states to publish draft guidance for public comment in the spring of 1997 and to issue final guidance to its regions in the summer of 1997. The interim memorandum sets forth six general criteria for voluntary programs, directing that they (1) provide for meaningful levels of community involvement, (2) use protective cleanup requirements, (3) have adequate resources, (4) ensure the completion of cleanups, (5) oversee cleanups, and (6) take enforcement action if necessary. According to EPA officials, the memorandum establishes broad criteria in order to encompass a wide variety of voluntary programs. EPA expects that individual regional officials will use their own judgment to determine whether a particular program is meeting the criteria. Upon determining that a program does meet the criteria, EPA plans to assume that it generally will not take additional action at sites in the program. Although the states would like EPA to release volunteers in programs meeting the agency’s criteria from any future federal liability, EPA reserves the right to invoke its federal enforcement authority if it determines that a voluntary cleanup in an approved program is not effective and protective.

Not all of the 10 initial agreements would satisfy all of the criteria set forth in EPA’s interim memorandum. For example, Colorado does not have the ability to take enforcement action at voluntary sites should such action become necessary. Also, some of the initial agreements contain provisions that are not included in other agreements or addressed in the interim memorandum. For instance, the agreement between Texas and Region VI allows some sites needing cleanups under RCRA to be cleaned up under the state’s voluntary program, while other agreements do not admit such sites into their program.

EPA’s Criteria Do Not Clearly Define Elements of Voluntary Programs

To accommodate the differences in states’ voluntary cleanup programs, EPA developed very broad criteria for its interim memorandum. The states supported this approach because they were concerned that detailed criteria might require them to change the voluntary programs each has developed to respond to its unique conditions. Although EPA needs to make the criteria flexible to accommodate a wide range of voluntary programs, the interim memorandum provides very little information on the kinds of activities and approaches that EPA would find acceptable in exchange for a statement that it would generally not plan further action at sites involved in such programs. Using this memorandum, EPA regions may have difficulty determining which programs meet the criteria and are protective of human health and the environment. For example, the criterion specifying that voluntary programs should have protective cleanup requirements, while implying a need for adequate monitoring, does not explicitly mention the importance of monitoring a volunteer’s efforts to operate and maintain nonpermanent remedies or land-use restrictions. Similarly, the criterion for overseeing cleanups, while addressing a general need, does not specify what oversight practices are acceptable in voluntary programs. Given the wide range of oversight approaches in the states we surveyed, further definition of acceptable practices is needed. Finally, the criterion calling for voluntary programs to provide for meaningful levels of community involvement does not define what program provisions would constitute such involvement.

Without further clarification, states with a voluntary program will have difficulty determining whether their program meets EPA’s criteria and may be deterred from negotiating an agreement with EPA. States developing a program will be unsure what elements their program needs to qualify for such an agreement.

Conclusions

The states we surveyed have developed successful voluntary cleanup programs, in part by offering to limit future state liability for volunteers. These states believe that their programs would be even more successful if they could clarify the extent to which their volunteers are likely to face future federal liability. While EPA is interested in supporting voluntary programs in this manner, it also has an interest in ensuring that these programs are achieving protective cleanups before it agrees to plan taking no further action at sites in the programs.

Given that EPA’s regions will use the agency’s guidance to make this judgment, the guidance must clearly define the elements that EPA believes these programs should include, particularly in the three areas we identified. Without more clearly defined criteria, a region could enter into an agreement with a state whose program’s provisions might not be adequate for EPA to fulfill its responsibility under the current law to ensure protective cleanups. We recognize that neither EPA nor the states want to be overly prescriptive in the requirements they design for voluntary cleanups because many sites may not warrant such requirements and imposing them could discourage participation. Consequently, to better define its criteria for voluntary programs in its final guidance, EPA could look to the models implemented by several states that vary their requirements with the risks and conditions at individual sites.

Recommendation

We recommend that the Administrator, EPA, work with the states to more clearly define in the agency’s final guidance the criteria that state voluntary cleanup programs should meet to obtain an agreement limiting EPA’s involvement at sites, particularly in the areas of monitoring after cleanup, acceptable oversight practices, and public participation. EPA could consider as possible models the approaches that several state programs have taken to tailor the requirements for cleanups to the risks and conditions at individual sites.

Agency Comments

EPA officials, including the Director of the Outreach and Special Projects Staff, the office responsible for voluntary cleanup initiatives in EPA’s Office of Solid Waste and Emergency Response, agreed with the content and presentation of information in the report and suggested several technical revisions, which we incorporated. Observing that our recommendation addressed several of the most important issues in crafting a policy on state voluntary cleanup programs, these officials said they would consider it as they develop the agency’s final guidance. The representative of the Association of State and Territorial Solid Waste Management Officials, who has been involved in the organization’s task force on cleanup programs, also suggested several changes to clarify steps taken by the states to ensure effective voluntary cleanups, and we incorporated this information in the report. In commenting on our recommendation, he agreed that the states must work closely with EPA on the final guidance to ensure that it reflects the distinct perspectives and the variety of approaches that the states have taken in implementing voluntary cleanup programs.

Characteristics of Each Voluntary Program

X Volunteers in Massachusetts may attempt to clean their sites within 1 year of discovering them. If they cannot complete a cleanup in that time, they clean under the state’s longer-term program, which has different requirements.

Washington volunteers may choose between voluntary cleanup programs. Washington state officials have not kept statistics about cleanups at IRAP sites. As an alternative, volunteers may negotiate an agreement with the state and clean up under the state’s oversight.

Voluntary Cleanup Programs’ Requirements for Monitoring After Cleanup

The volunteer must submit progress reports on the status of any operating treatment system for the lifetime of the system and evaluate the cleanup every 5 years.

The volunteer must submit reports on site conditions to the state.

The volunteer must submit reports on site conditions to the state.

The state does not monitor a site after the final cleanup report is approved.

The volunteer submits reports and estimates when operations and maintenance will be completed.

The state uses licensed site professionals to manage and approve cleanups. These professionals must monitor any sites that require long-term monitoring and report periodically to the state. In addition, the state may audit sites for 5 years after their cleanup is complete and audits 20 percent of all completed sites. If a problem is found at this time, the state may continue to monitor for another 5 years.

Voluntary Cleanup Programs’ Requirements for Oversight

Review of final report; sampling Review of final report; sampling if needed The state specifies reporting, oversight, and approval requirements, but the licensed site professional carries them out. The state conducts its own oversight at sites that pose high risks or imminent hazards. The state audits up to 20 percent of all completed cleanups.

For the few sites that are cleaned up to site-specific standards, Pennsylvania establishes more stringent oversight requirements, including requirements for three or more reports and site visits.

For sites where cleanups are carried out without the state’s approval or agreement, only the final report is reviewed.

Voluntary Cleanup Programs’ Requirements for Public Participation

The volunteer must describe the community near the site as part of the application. The state bases the public participation requirements and the proposed cleanup activities on this profile. The volunteer is required to hold a public meeting for sites costing more than $1 million.

The volunteer must publish a notice in a local newspaper about the cleanup before the cleanup begins. If there is public interest, the state may require a public meeting.

The volunteer is required to make the cleanup plan available for public comment for 30 days. The volunteer may hold a public meeting if one is requested.

The volunteer must make the cleanup plan publicly available and publish information on major milestones in a local newspaper. If at least 10 people request a public participation plan, the volunteer must develop one.

The volunteer must make the cleanup plan publicly available and publish information on major milestones in a local newspaper. If at least 10 people request a public participation plan, the volunteer must develop one.

The state does not have specific requirements but may require public participation activities in some cases. At a minimum, the state notifies local officials that a voluntary cleanup is planned for their community.

When a volunteer wants a covenant-not-to-sue, which provides the maximum release from state liability, the volunteer must conduct hearings. The volunteer must publish a notice in a local newspaper if the selected cleanup standards do not allow for future residential use.

After the cleanup is completed and the state has awarded a covenant-not-to-sue, the state publishes a notice in a local newspaper.

If the volunteer plans to use the state-established cleanup standards, it must publish a notice in a local newspaper before starting the cleanup. If the volunteer plans to develop its own standards instead of using the state-established standards, local government officials may require public participation.

The volunteer must publish a notice in a local newspaper upon entering the program and after completing the cleanup plan. The public may request a meeting.

The volunteer must notify owners of neighboring property if contamination at the site could migrate to the other property.

The volunteer must publish a variety of notices in a local newspaper, obtain public comments, and hold public meetings.

The state may require activities such as publishing a notice in a local newspaper, holding public meetings, or creating local mailing lists, depending on conditions at the site and the level of public concern.
