Superfund: evaluating the impact of executive order 12898.
BACKGROUND: The U.S. Environmental Protection Agency Environmental Protection Agency (EPA), independent agency of the U.S. government, with headquarters in Washington, D.C. It was established in 1970 to reduce and control air and water pollution, noise pollution, and radiation and to ensure the safe handling and (EPA EPA eicosapentaenoic acid.

OBJECTIVE AND METHODS: I use event history analysis to evaluate the impact of Executive Order 12898 on the equitability of the Superfund program.
DISCUSSION: Findings suggest that despite environmental justice legislation, Superfund site listings in minority and poor areas are even less likely for sites discovered since the 1994 Executive Order.
CONCLUSION: The results of this study indicate that Executive Order 12898 for environmental justice has not increased the equitability of the Superfund program.

In the early 1980s environmental justice became widely recognized, as minority and low-income neighborhoods fought to keep environmental hazards 'Environmental hazard' is a generic term for any situation or state of events which poses a threat to the surrounding environment. This term incorporates topics like pollution and Natural Hazards such as storms and earthquakes. out of their communities and away from their families. Researchers began to analyze and document environmental injustices around the country and found that minorities and poor were in fact, more frequently living near environmental hazards [Bullard 1983; United Church of Christ United Church of Christ, American Protestant denomination formed in 1957 by a merger of the General Council of Congregational Christian Churches (see Congregationalism) and the Evangelical and Reformed Church. (UCC An abbreviation for the Uniform Commercial Code. ) 1987; U.S. Government Accounting Office (U.S. GAO) 1983]. As the environmental justice movement began to grow in strength, the U.S. Congress and President Carter established the Comprehensive Environmental Response Compensation and Liability Act or CERCLA CERCLA Comprehensive Environmental Response, Compensation, and Liability Act (aka SuperFund) (1980). As part of CERCLA and in an effort to address hazardous waste sites across the country, the U.S. Environmental Protection Agency (EPA) must locate and prioritize pri·or·i·tize

Although the specific ways in which toxins in the ground, water, or air produce adverse health effects in humans are still disputed, the toxicity toxicity /tox·ic·i·ty/ (tok-sis´i-te) the quality of being poisonous, especially the degree of virulence of a toxic microbe or of a poison. of such sites and potential risks posed to human populations and the environment certainly warrant attention. As of March 2003, there were 1,484 sites on the Superfund list, and over 6.5 million people living in census tracts A census tract, census area, or census district is a particular community defined for the purpose of taking a census. Usually these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county. with Superfund sites (O'Neil 2005).
Ideally the process of moving a site to the federal Superfund list would be related solely to the severity of hazard posed to the surrounding populations. However, other social forces shape the listing of a Superfund site. A site could be listed because of its hazardousness, or conversely con·verse 1

2. it could be listed because it is less hazardous and therefore easier to clean (Daley and Layton 2004). Moreover, a site could also move more quickly through the listing process because it is in a community perceived to have more power through access to resources because individuals residing in the area have higher incomes or because of racial or ethnic composition of the area. This environmental cleanup injustice has been supported by research demonstrating that representation of minorities and low-income populations is lower in areas with Superfund sites, indicating these populations are not benefiting equally from the Superfund program (Anderton et al. 1997; Hird 1993; O'Neil 2005). In this article I describe the analysis of how of a hazardous site is placed on the Superfund list and further evaluate the effects of legislation intended to make such processes more equitable.
In February 1994, in an attempt to remedy environmental injustice, President Clinton established Executive Order 12898. The order required that each Federal agency shall make achieving environmental justice part of its mission by identifying and addressing, as appropriate, disproportionately dis·pro·por·tion·ate

2. To refine or purify, especially by distillation. environmental problems that have disproportionately affected minority and low-income populations. The order specifically names these populations and requires that agencies address policies and programs that may adversely affect these populations in particular. However, the order and its implementation have been criticized [Murphy-Green and Leip 2002; U.S. Government Accountability Office The Government Accountability Office (GAO) is the audit, evaluation, and investigative arm of the United States Congress, and thus an agency in the Legislative Branch of the United States Government. 2005 (the U.

(U.S. OIG Noun 1. OIG - the investigative arm of the Federal Trade Commission

In this present study, I evaluate the effects of Executive Order 12898. It has now been over a decade since the executive order, yet the effect of this order on programs such as Superfund has not been critically examined. This historical, national, census tract-level study adds important new information to the field of environmental justice by examining justice in environmental remediation Generally, remediation means providing a remedy, so environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water for the general protection of human health and the environment or from a , also known as environmental cleanup justice. The main questions in the present study are a) what demographic factors are associated with the chances of being placed on the Superfund list, and b) has the executive order affected the chances of listing for minority and poor populations? This study includes U.S. EPA Hazardous Ranking Scores (HRS hrs abbr (= hours) → h

It reflects the phenomenon that a covariate is not necessarily fixed. For instance, if one wishes to examine the link between area of residence and cancer, this would be complicated by the . This is the first evaluation of the equitability of Superfund listings since Executive Order 12898 and will add significantly to environmental cleanup justice theory as well as policy debate regarding both Superfund and the executive order.

1. by environmental hazards. Although some researchers have asserted that the disproportionate burden of waste is solely associated with income (Bowen et al. 1995; Szasz 1994), other researchers have supported (to varying degrees) the claim that both minorities and the poor are disproportionately affected by environmental burdens (Anderton et al. 1994a, 1994b; Been 1993, 1994; Been and Gupta 1997; Bullard 1993; Bullard et al. 1994; Daniels and Friedman 1999; Downey 1998; Faber and Krieg 2001; Krieg 1995; Logan and Molotch 1987; Mohai and Bryant 1992).
Athough there is an abundance of research on environmental burdens and environmental justice, far fewer studies examine the relationship between environmental remediation and environmental justice, or environmental cleanup justice. The distinction between these two concepts has not been clearly demarcated. Environmental justice and cleanup justice studies have been combined indiscriminately, using Superfund as an indicator of environmental equity (Downey 2005; Krieg 1998; Stretesky and Hogan hogan
Dwelling of the Navajo Indians of Arizona and New Mexico. The hogan is roughly circular and constructed usually of logs, which are stepped in gradually to create a domed roof. 1998). However, this assumes that Superfund sites are similar to other environmental hazards such as toxic releases, incinerators, and other hazardous facility sitings. Superfund is and should be a distinctly different analysis in environmental justice. Unlike general environmental justice studies regarding disproportionate exposure or proximity to hazards at risk; liable to suffer damage or loss.
See also: Hazard , the Superfund program is an environmental cleanup program that requires resources and symbolizes an environmental benefit. The cleanup of hazardous waste sites is enormously costly, and therefore clean environments take up limited resources. These resources, not unlike other limited resources, may not be distributed evenly throughout the population, and it is likely that minorities and low-income groups are underrepresented un·der·rep·re·sent·ed

Sites may be discovered and never proposed to the Superfund list, or sites may be proposed to the Superfund list but never make the list.

rep equity, the degree to which populations are proportionately represented in the Superfund program (Anderton et al. 1997; Hird 1993; Zimmerman 1993). This small group of Superfund equity research includes a study claiming that minority and poor populations are found in higher percentages in communities with NPL sites (Zimmerman 1993). This suggests that Superfund mimics traditional environmental justice literature, which shows that minorities are overrepresented o·ver·rep·re·sent·ed
Represented in excessive or disproportionately large numbers: "Some groups, and most notably some races, may be overrepresented and others may be underrepresented" in proximity to environmental burdens and are also overrepresented in the Superfund program. However, Zimmerman's research excluded rural sites, and because of the strong association between urban environments and minority and poor populations, the exclusion of these sites may have severely biased results (Anderton et al. 1997; O'Neil 2005). Further research using a national sample and county-level data found inconsistent results and reported that although the poor were less likely to be represented in Superfund and the wealthy more likely to be represented in Superfund--as environmental cleanup justice would suggest--minorities were in fact also more likely to live near such sites (Hird 1993). Therefore, testing of the environmental justice hypothesis has, thus far, produced mixed results. A national censustract level, Superfund equity study (Anderton et al. 1997) further supported the idea that the wealthiest as well as the poorest were excluded from Superfund and concluded that census tracts with Superfund sites "are typically working class communities with fewer minorities, are less densely populated pop·u·late
tr.v. pop·u·lat·ed, pop·u·lat·ing, pop·u·lates

2. , and have more industrial employment." This study also concludes that as the percentage of Blacks or Hispanics and socioeconomically disadvantaged families increases in a neighborhood, the risk that CERCLIS CERCLIS Comprehensive Environmental Response, Compensation, and Liability Information System (formerly ERRIS; US EPA) [Comprehensive Environmental Response and Liabilities Information System database] sites will be placed on the NPL decreases. (Anderton et al. 1997)
This clearly supports the environmental cleanup justice theory. Additionally, a ZIP code-level study claimed that Superfund sites in minority and poor areas take longer to reach the NPL and subsequently take longer to be cleaned. These authors also concluded that cleanups at sites in these areas are also not enforced to the same degree as in white or wealthier areas (Lavelle and Coyle 1992). Therefore, studies up to this point have shown mixed results regarding which populations are most likely to benefit from the Superfund program. However, there is evidence that the poor, and in some cases minorities, are underrepresented in the Superfund program and may not be benefiting equally from environmental cleanups.
Superfund at Zero
The Superfund program has been under intense scrutiny and criticism since its inception. When the program was created, there is no doubt that the depth, breadth, and complexity of the hazardous waste problem in our nation was seriously underestimated. It did not take long for critics to begin citing how the Superfund program had failed the nation. It was believed that the cleanups were taking too long, there were too few of them, and they were taking too many resources. Tracking progress for so many complicated projects was certainly a challenge (Probst and Sherman 2004). The program could be further criticized for not adequately addressing the potential risks of sites and not prioritizing site cleanups based on potential risk [Environmental Law Institute (ELI Eli (ē`lī), in the Bible, high priest and judge of Israel, teacher of the boy Samuel.

However, the U.S. EPA consistently has been given near impossible tasks, unrealistic deadlines, and inadequate funding (ELI 1999; Lazarus 1991; Probst and Sherman 2004).
Historically one of the main reasons for a community or local or state officials to support a Superfund listing was the eligibility to receive federal funding for cleanup through the Superfund. Because the cost of Superfund cleanups has proven to be exorbitant, the eligibility for federal cleanup funds has been imperative in many situations. In the early 1980s, most state agencies handed over sizeable hazardous waste sites to the U.S. EPA without delay. However, since that time many states have developed comprehensive state superfund programs, and often states are able to handle the cleanup of sites without any federal intervention Federal intervention (Spanish: Intervención federal) is an attribution of the federal government of Argentina, by which it takes control of a province in certain extreme cases.

[Latin d . The Superfund program was originally financed by a tax levied on the petroleum and chemical industries. However, this tax expired in 1995, and although the fund officially reached a zero balance by the end of 2003, it is partially replenished by cost recovery lawsuits against responsible parties. Additional funds are allocated to Superfund projects from the general fund by congressional appropriations. Total expenditures for Superfund programs have remained between $1.41 billion in 1995 to $1.24 billion in fiscal year 2004 [(U.S. GAO 2004]. Despite the decrease in the federal financing for Superfund projects, a listed Superfund site still has the potential for more funding when compared with the monies available at the state level. Therefore, despitethe criticisms levied at the program and how long site cleanups may take, and even though the Superfund program itself has reached a zero balance, the program is still beneficial for sites requiring massive cleanup and/or having no other potential sources for cleanup money. Becoming officially placed on the NPL is a critical step toward acquiring funding necessary for such cleanups.
Executive Order 12898
Since 1994, when President Clinton signed Executive Order 12898 for environmental justice (Clinton 1994), minority and low-income populations should have been benefiting proportionately from environmental cleanups through the Superfund program. The order specifically demands that agencies, including the U.S. EPA, ensure that their policies and programs do not disproportionately affect minorities and poor. However, whether the agency has complied with this order and to what degree has been questioned.
EPA is essentially relying on state and local governments to deal with the environmental justice concerns...even though the executive order does not apply to state or local governments, and, absent specific state or local law, they have no obligation to consider environmental justice. . . . (U.S. GAO 2005)
EPA has not fully implemented Executive Order 12898 nor consistently integrated environmental justice into its day-to-day operations. EPA has not identified minority and low-income, nor identified populations addressed in the Executive Order, and has neither defined nor developed criteria for determining disproportionately impacted. (U.S. OIG 2004)
A study examining the executive order as it applies to pesticides in the State of Florida concluded, "the goals of the Executive Order 12898 are not being achieved by the U.S. Environmental Protection Agency" (Murphy-Green and Leip 2002).
Although these reports indicate that the executive order has not been complied with or implemented, many regional U.S. EPA offices are working tirelessly tire·less

tireless·ly adv. on programs to increase environmental equity. In 2004 the Office of Environmental Justice released a report (U.S. EPA 2005) highlighting regional environmental justice programs and pilot projects. There are a tremendous number of such projects, showing sincere commitment to environmental justice at the regional level. However, without support at the federal level, these programs are left without federal funding and are inconsistent across the nation. Because neither minority nor low-income have been defined at the federal level, regional offices are left attempting to create these definitions on their own and using regional funding to implement programs.
[In] the absence of environmental definitions, criteria, or standards from the Agency, many regional and program offices have taken steps, individually to implement environmental justice policies. This has resulted in inconsistent approaches by regional offices. (U.S. OIG 2004)
In 2001 then U.S. EPA administrator Christine Todd Whitman virtually rewrote Executive Order 12898 and removed the considerations for populations most affected by environmental hazards--minorities and the poor (Whitman 2001). In the memorandum she redefines environmental justice to mean the fair treatment of people of all races, cultures, and incomes with respect to the development, implementation and enforcement of environmental laws and policies, and their meaningful involvement in the decision making process of the government. (U.S. OIG 2004)

3. , the memorandum is and was not the letter or the spirit of Executive Order 12898. The original wording of the 1994 executive order, required specifically "identifying and addressing" programs that disproportionately affect "minorities and low-income groups." The order clearly requires agencies to take special consideration of populations that historically have been overburdened with environmental hazards. In contrast, Whitman's 2001 memorandum indicates a distinct policy shift; agencies are being told they no longer need to consider race, ethnicity ethnicity Vox populi Racial status–ie, African American, Asian, Caucasian, Hispanic , or other socioeconomic indicators in their programs or policies. Although this 'blind' justice may seem impartial Favoring neither; disinterested; treating all alike; unbiased; equitable, fair, and just. , these agencies, and the U.S. EPA in particular, were told nearly 7 years before to specifically target populations to ensure proper and proportional treatment. Furthermore, it disregards the historically inequitable treatment and burden that minorities and the poor have born and the reason why the order was constructed initially.
The lack of direction and guidance that appears to be coming from the highest levels at U.S. EPA certainly will have consequences on the ability for regional offices to effectively implement consistent environmental justice programs. Furthermore, it will undoubtedly affect a national evaluation of the Superfund program specifically. In this article I explore how effective Executive Order 12898 has been and what impact it has had on the equitability of Superfund listings.
Event history analyzes the risk of an event or hazard, given a set of influencing variables. Environmental cleanup justice research such as that presented in this article seeks to determine if population characteristics influence the Superfund listing process. Using time varying covariates in event history analysis assures that current demographic patterns are not used to explain past Superfund listings. Instead of including independent variable information for only one point in time, event history analysis allows the variable to change over time. This is particularly important for environmental justice research, which has been plagued with the inability to show which came first, hazards or marginalized populations.
The data used in this research are the total population of sites within the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. , in the Superfund program that have reached proposal to the Superfund list by March 2003 (N = 1,540) (U.S. EPA 2003). This is the entire set of such sites and is therefore, population-level data. Comparing the chance of listing for sites that have already reached the proposal stage allows for inclusion of HRS. This score is used to help the U.S. EPA decide whether a site qualifies for the Superfund program. However, using all proposed sites can and should be considered a very conservative measure of those at risk of making the Superfund list. There is no doubt a level of power is necessary to have a site officially recognized as discovered by the U.S. EPA, let alone proposed for the Superfund program. Therefore, the conclusions made within should be considered conservative.
Superfund sites were matched to demographic census data by 2000 census tract. The choice of spatial variables in environmental justice or environmental equity studies is always contentious. It is imperative that the unit of analysis accurately portrays the affected community (Bowen 2001; Mohai P, Saha R, unpublished data, 2003). Within traditional environmental justice research, arguments about spatial units are most often in reference to or questioning whether or chosen unit is truly an exposed population; this is not an issue in this present study. Here, the unit of analysis is the group that generally surrounds the site and is also considered to be or perceived as being affected by the site, not those that are exposed such as in traditional environmental justice research. Therefore, although a county would be much too large, a census block A census block is the smallest geographic unit used by the United States Census Bureau for tabulation of 100-percent data (data collected from all houses, rather than a sample of houses). Several blocks make up block groups, which again make up census tracts. would be far too small and could also contain a greater variation in population size. The unit that is most appropriate would be the ZIP code zip code

In this case, we have chosen census tract. Again, this should be considered a conservative choice. Support for the choice of census tracts as the unit of analysis is found throughout environmental justice and Superfund research (Anderton et al. 1994a, 1994b, 1997; Been 1994; Been and Gupta 1997; Boer et al. 1997; Bowen and Haynes 2000a, 2000b; Feldmen and Hanahan 1996; Mitchell et al. 1999; Stretesky and Hogan 1998; Stretesky and Lynch 1999; Yandle and Burton 1996).Because the 2000 census tract was available for each of the sites in the Superfund data set, it was the starting point Noun 1. starting point - earliest limiting point

Event history analysis requires that independent time-varying covariates change at the same interval as the dependent variable. This means that independent demographic census variables that change over time, such as percentage minority or mean family income, must be measured in the same time intervals as the dependent variable--U.S. EPA Superfund listing decisions. A yearly time interval was chosen as the most appropriate interval estimation In statistics, interval estimation is the use of sample data to calculate an interval of possible (or probable) values of an unknown population parameter. The most prevalent forms of interval estimation are confidence intervals (a frequentist method) and credible intervals (a of Superfund listings.

Environmental justice literature indicates that women and people of color have historically fueled the grassroots activism of the environmental justice movement (Brown and Mikkleson 1997; Bullard 1990, 1993; Cable 1992; Edelstein 1988; Faber 1998; Levine 1982). Additionally, research focusing on gender and the environment indicates that women display greater concerns regarding local environmental hazards (Blocker and Eckberg 1989; Davidson and Freudenburg 1996; Flynn et al. 1994; Krauss 1993; Stern et al. 1993; Van Liere and Dunlap 1980). This research implies that women exhibit more concern over local environmental hazards because of their role as caregivers and nurturers, which also implies a distinct relationship between environmental hazards and children, one in which children are protected from such hazards. Therefore, grassroots environmental justice, gender, and family indicators include percent of femaleheaded households and children. To control for the increases in industrialization industrialization

The changes that took place in Britain during the Industrial Revolution of the late 18th and 19th century led the way for the early industrializing nations of western Europe and that often occurred historically in highly populated city centers, two indicators of urbanization were included. The first is an urbanization indicator created by the U.S. census, which measures the percent of a tract living in an urban center (this is the only demographic variable that is does not vary over time; the value for the year 2000 is used for each case). The second, population density, is the number of persons (thousands) per square mile.

What Are the Chances of Making the Superfund List?
Generally, inclusion on the Superfund list does not appear as likely for sites in areas with high minority and poor populations (Table 1). Increases in minority populations, families in poverty, or people without high school diplomas all lower the chances of a Superfund listing. The data indicate that a 1% increase in minority is associated with a 0.2% decrease in the chance of a Superfund listing. Using the (Exp (b)-1) ??100 method, a multiplicative mul·ti·pli·ca·tive

2. Having to do with multiplication.
mul method, therefore indicates that a 10% higher minority population lowers the chance of a Superfund listing by 2%, whereas a 10% higher poverty rate lowers the chance of being listed by 13%. Conversely, a site with a $10,000 higher mean income has a 9% greater chance of making the Superfund list (note the variable was measured in thousands). These results further indicate that minorities and the poor are not benefiting from Superfund cleanups, whereas wealthier communities have a greater chance of obtaining this benefit.

Results for Hispanic and Native Americans, more specifically, are not the same. Sites in areas with higher Hispanic or Native American populations actually have greater chances of being placed on the Superfund list. Sites in areas with high percentages of female-headed households have greater chances of being listed. Because women, and specifically women of color not of the white race; - commonly meaning, esp. in the United States, of negro blood, pure or mixed.

Whether these women have had a great impact on the Superfund program cannot be discerned from these data, but considering these women may otherwise be considered a marginalized population, it is interesting to find this population has a greater chance of Superfund listings.
Site-specific variables also help in identifying the chance of a Superfund listing. Specifically, the identification of a PRP PrP A prion protein.

To evaluate the impact of Executive Order 12898 on Superfund listings pre-and postexecutive order, Superfund sites were tested using the previous model. The data set was split into sites discovered before 1994 and sites discovered in 1994 or later. The number of sites discovered in 1994 or later is small (61 cases), but this should not affect the conclusions drawn from this group, as these arepopulation data. However, this should encourage further research into these trends when more data are available.

v.intr. from this comparison is that the chance of listing for several marginalized and poor populations actually worsens for sites discovered since the executive order (Table 2). For example, for sites discovered in 1994 or later, a 10% higher minority population lowers the chance of listing 7% (compared with 3% for early sites), and a 10% higher Native American population lowers the chance of a site making the list by almost 80% (compared with a 3% greater chance pre-executive order). Poorer populations are also less likely to be placed on a Superfund list after the executive order; a 10% increase in poverty decreases the chances of listing by 31% after the executive order (as opposed to 16% before the executive order).

Conversely, increases in income continue to be associated with greater chances of Superfund listing. Housing becomes an even stronger indicator of the chance of listing; increases in housing values and housing ownership indicate an increased chance of Superfund listing post-executive order. Other indicators of wealth are, at best, mixed for sites discovered in 1994 or later. For example, for sites discovered in 1994 or later, college educations and professional careers become associated with a decreased chance of making the list.
Another interesting finding post-executive order, is that higher percentages of people without high school diplomas actually increases the chance of listing. Other indicators such as lower incomes and lower housing values as well as higher poverty rates are associated with a lower chance of listing, whereas sites with greater percentages of people without high school diplomas increase the chance. It is possible that Superfund listings are more likely in areas where homeowners are less educated or are considered working class. This is supported to varying degrees by previous research, which indicated that both the wealthiest and poorest populations were not represented in Superfund and that Superfund is a working-class program (Anderton et al. 1997; Hird 1993; O'Neil 2005). It is possible that more powerful communities may attempt to rectify or remediate re·me·di·a·tion

Evidence further supports an environmental cleanup justice theory, suggesting that marginalized and poor populations are less likely to benefit from a cleanup program such as Superfund despite their overrepresentation in proximity to environmental hazards. These data indicate that even if sites in minority and poor areas do make it into the Superfund program, they have less chance of making the official Superfund list. Being placed on the official Superfund list is a critical step in securing funding for hazardous sites, especially as these sites are now financed through Senate appropriations. Sites not officially listed in the program will have significant difficulty obtaining necessary funding from the government. For sites with exorbitant cleanup costs and no other potential funding sources, listing on the Superfund is still critical.
Past research-excluding factors such as the HRS and PRPs may have missed important aspects of the Superfund process. Despite that the U.S. EPA uses the HRS only to qualify sites for the NPL and not for a literal In programming, any data typed in by the programmer that remains unchanged when translated into machine language. Examples are a constant value used for calculation purposes as well as text messages displayed on screen.

It is possible that sites with high HRSs are sites that also often require intensive negotiation with PRPs. Extremely hazardous sites with a viable PRP may become enmeshed en·mesh also im·mesh

It is also possible that very hazardous sites are also more difficult (and take longer) to analyze, create a hazard score for, and prepare for proposal and therefore listing. Alternatively, previous research has indicated, "EPA is more likely to tackle "easier" or low-risk sites" (Daley and Layton 2004). These authors theorized that tackling the lower-risk sites was a pragmatic approach for an agency faced with serious financial constraints CONSTRAINTS - A language for solving constraints using value inference.
["CONSTRAINTS: A Language for Expressing Almost-Hierarchical Descriptions", G.J. Sussman et al, Artif Intell 14(1):1-39 (Aug 1980)]. and much criticism in terms of results. These data further support this theory and suggest that less hazardous sites have a greater chance of reaching an official Superfund listing.
Perhaps more important, the use of HRS controls for the hazardousness of the site in this analysis. Therefore, although it could be argued that perhaps sites in minority and poor areas are not making the list because they are not as hazardous, this analysis controls for just that fact. Furthermore, because the data set includes sites already proposed for Superfund listing, the sites have all qualified for the Superfund in terms of their hazard.
The relationship between the chance of listing and the identification of a PRP is complex. Results show an inconsistent relationship and suggest further research into the nuances of this association. For all sites in the data set, and for the first 13 years of Superfund specifically, the identification of a PRP actually increased the chance of a Superfund listing. Because of the severe financial constraints on the Superfund program and the exorbitant costs of cleanups coupled with inadequate funding, it is possible thatsites with PRPs move through the program more quickly because of the potential for external funding. A site is placed on the official Superfund list has legal benefits through the long reach of the Superfund's joint and several liabilities clause. This clause states that parties responsible for waste at a Superfund site can be held liable even if they did not intend to pollute pol·lute

2. To make less suitable for an activity, especially by the introduction of unwanted factors. and that all parties that handled the waste can be pursued. The percentage of sites cleaned using funds from PRPs is estimated as high as 70% (U.S. EPA 2000). Therefore, sites with PRPs may be easier to list because they may be perceived as not competing for the scarce cleanup resources provided by the Superfund.
However, for sites discovered since 1994, the opposite was found; sites with identified PRPs have a lower chance of reaching official Superfund listing designation. There are several possible reasons why a site with a PRP may take longer or have a lower chance to reach the list. First, a PRP may wish to contest the listing process to avoid the stigma stigma: see pistil.

scarlet letter and financial burden that comes with a Superfund label. Furthermore, a company could enter into an agreement with the U.S. EPA to clean the site, with the understanding that the U.S. EPA will not put the site on the official Superfund list. This would cause a site to remain in the proposal stage until the company and the U.S. EPA decide that the site is clean, lowering the chance of reaching listing. These results may indicate that PRPs now more than ever avoid or attempt to avoid Superfund and negotiate and pay for cleanups outside the boundaries of the Superfund program. However, the complex relationship between PRPs and listing cannot be fully established with these data, and further research is encouraged.

However, the results of the present study show the opposite; in general, the results further support the conclusion that sites discovered in 1994 or later put minorities and the poor at even lower chances of listing than in previous years--a conclusion that is quite controversial considering the specific requirements of Executive Order 12898. It is possible that the benefits of environmental justice programs implemented in the wake of the order are not yet showing in the results of this study, or that the addition of new sites will show a more equitable trend. It is also possible that the U.S. EPA has focused environmental justice efforts toward other programs such as the Brownfield See greenfield. cleanups.

Last, it is possible that the U.S. EPA has chosen to focus on the cleanup of Superfund sites rather than the equitable listing of such sites. Nearly 80% of all deleted sites have been deleted since 1994 (214 of 269) (O'Neil 2005).
The results of the present study suggest that for sites discovered after the 1994 Executive Order 12898, there is even a lesser chance for Superfund listing for marginalized and poor populations.

In addition, the order fails to define minority or low income that has caused regional discrepancies. Furthermore, the Office of Environmental Justice, "does not provide funding, and has no authority over the program and regional offices regarding efforts to integrate environmental justice" (U.S. OIG 2004). The commitment to environmental justice at the highest levels of the U.S. EPA could be described as inconsistent and even contradictory.

The U.S. EPA needs to recognize the original intent of Executive Order 12898 and reestablish the environmental justice mission. The order expressly notes that, each Federal agency shall conduct its programs policies and activities that substantially affect human health or the environment, in a manner that ensures that such programs, policies and activities do not have the effect of excluding persons (including populations) from participation in, denying persons (including populations) the benefits of, or subjecting persons (including populations) to discrimination under, such, programs, policies, and activities because of their race, Color or national origin.
