Understanding water quality trading: the basics

The United States has entered a new era in water quality protection: the era of market-based incentives. In January 2003, the United States Environmental Protection Agency (EPA) issued its National Water Quality Trading Policy (Trading Policy) (USEPA, 2003). This action has generated greater interest in water quality trading and has prompted EPA to develop tools and training to assist interested parties in understanding what water quality trading is and what constitutes a successful trading program.     

Characterizing soils for hazardous waste site assessments

This paper provides a review and justification of the minimum data needed to characterize soils for hazardous waste site assessments and to comply with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Scientists and managers within the regulatory agency and the liable party need to know what are the important soil characteristics needed to make decisions about risk assessment, what areas need remediation and what remediation options are available. If all parties involved in characterizing a hazardous waste site can agree on the required soils data set prior to starting a site investigation, data can be collected in a more efficient and less costly manner. Having the proper data will aid in reaching decisions on how to address concerns at, and close-out, hazardous waste sites.This paper was prepared to address two specific concerns related to soil characterization for CERCLA remedial response. The first concern is the applicability of traditional soil classification methods to CERCLA soil characterization. The second is the identification of soil characterization data type required for CERCLA risk assessment and analysis of remedial alternatives. These concerns are related, in that the Data Quality Objective (DQO) process addresses both. The DQO process was developed in part to assist CERCLA decision-makers in identifying the data types, data quality, and data quantity required to support decisions that must be made during the remedial investigation/feasibility study (RI/FS) process. Data Quality Objectives for Remedial Response Activities: Development Process (US EPA, 1987a) is a guidebook on developing DQOs. This process as it relates to CERCLA soil characterization is discussed in the Data Quality Objective Section of this paper.     

Use of the instream flow incremental methodology: A tool for negotiation

The resolution of conflicts arising from differing values and water uses requires technical information and negotiating skills. This article outlines the Instream Flow Incremental Methodology (IFIM), developed by the US Fish and Wildlife Service, and demonstrates that its use to quantify flows necessary to protect desired instream values aids negotiation by illustrating areas of agreement and possible compromises between conflicting water interests. Pursuant to a Section 404 permit application to the US Army Corps of Engineers made by City Utilities of Springfield, Missouri, in 1978, IFIM provided the means by which City Utilities, concerned with a secure water supply for a growing population, and those advocating instream values were satisfied that their requirements were met. In tracing the 15-month process, the authors conclude that the application of IFIM, as well as the cooperative stance adopted by the parties involved, were the key ingredients of the successful permit application.     

Siting a liquid hazardous waste incinerator: Experience with California's tanner act

The siting of hazardous waste facilities is complex, controversial, time-consuming, expensive, and sometimes impossible. Pressures for and against these facilities are immense. California is developing the “Tanner process,” a one-stop concept in which a single agency serves as the focal point (lead agency) for all the state institutions involved. In this paper I review the experience gained to date with the proposal for the largest liquid toxic waste incinerator proposed for California. I present positive and negative aspects of the process, and draw some policy conclusions. I explore a key policy goal: the search for win/win solutions such that both the community and industry come out ahead environmentally and economically. The experience, especially the approach to negotiation/discussion, is a model for possible use elsewhere in California and the nation.     

Theory and practice of EIA implementation: A comparative study of three developing countries

This article offers a conceptual framework for analyzing institutional processes and performance outcome of EIA implementation for developing countries. Eight classes of participants in the EIA process are identified: (1) responsible agency; (2) action proponent; (3) preparer; (4) review agency; (5) rule-setting agency; (6) concerned agencies; (7) general public; and (8) licensing agency. Five types of performance outcome are suggested that may follow the introduction of EIA into a national planning system. These include EIA as (1) a fully internalized element of the planning process, (2) a support for a position of advocacy for the environment, (3) a process of adjustment among conflicting goals, (4) a process to remedy prior environmental damage, and (5) a perfunctory endorsement of public or private actions. Using these categories, the EIA system of the Philippines, Korea, and Brazil are analyzed. Three aspects of EIA implementation are compared: national development planning and environmental goals; institutional structure; and performance evaluation. Based on this analysis, the author concludes that while EIA in developing countries is being hampered in its early stages by institutional factors, there are some specific policies that, if adopted by national governments and international aid agencies, would enhance the integration of EIA into the planning and decision-making process and make EIA a more effective tool for environmental protection in the developing world.     

Proponent-Indigenous agreements and the implementation of the right to free,prior, and informed consent in Canada

Indigenous peoples have gained considerable agency in shaping decisions regarding resource development on their traditional lands. This growing agency is reflected in the emergence of the right to free, prior, and informed consent (FPIC) when Indigenous rights may be adversely affected by major resource development projects. While many governments remain non-committal toward FPIC, corporate actors are more proactive at engaging with Indigenous peoples in seeking their consent to resource extraction projects through negotiated Impact and Benefit Agreements. Focusing on the Canadian context, this article discusses the roots and implications of a proponent-driven model for seeking Indigenous consent to natural resource extraction on their traditional lands. Building on two case studies, the paper argues that negotiated consent through IBAs offers a truncated version of FPIC from the perspective of the communities involved. The deliberative ethic at the core of FPIC is often undermined in the negotiation process associated with proponent-led IBAs.     

Performance of EIA authority and effectiveness of EIA system in Pakistan

Environmental Impact Assessment (EIA) agencies worldwide face multiple challenges that compromise their performance and in turn EIA procedural effectiveness. The current study aimed to evaluate the performance of the Environmental Protection Agency (EPA) of Punjab, Pakistan and the problems it faces whilst implementing EIA and ensuring EIA effectiveness. Semi-structured interviews were used to collect data for the study. EPA performance and procedural effectiveness were evaluated using the formal and informal roles of EPA and EIA good practices respectively. They were also linked to regulatory framework, capacities of actors and contextual factors. Study found that EPA and EIA system performance is weak. Consequently, procedural effectiveness is compromised. The main causes include limited capacities of EPA, consultants and proponents; lack of political will; political interference and outdated regulations. A strong political will of the government is required to enhance the capacity of EPA and other actors in terms of motivation or “the will to” and means or “the ability to”. Measures taken by international EIA agencies to improve performance and effectiveness have also been discussed. Based on this study, lessons can be learnt by not only EPA Punjab but also other agencies in Pakistan and international agencies facing similar challenges.     

Exploring the use of computer models in participatory integrated assessment – experiences and recommendations for further steps

Integrated assessment (IA) can be defined as a structured process of dealing with complex issues, using knowledge from various scientific disciplines and/or stakeholders, such that integrated insights are made available to decision makers (J. Rotmans, Enviromental Modelling and Assessment 3 (1998) 155). There is a growing recognition that the participation of stakeholders is a vital element of IA. However, only little is known about methodological requirements for such participatory IA and possible insights to be gained from these approaches. This paper summarizes some of the experiences gathered in the ULYSSES project, which aims at developing procedures that are able to bridge the gap between environmental science and democratic policy making for the issue of climate change. The discussion is based on a total of 52 IA focus groups with citizens, run in six European and one US city. In these groups, different computer models were used, ranging from complex and dynamic global models to simple accounting tools. The analysis in this paper focuses on the role of the computer models. The findings suggest that the computer models were successful at conveying to participants the temporal and spatial scale of climate change, the complexity of the system and the uncertainties in our understanding of it. However, most participants felt that the computer models were less instrumental for the exploration of policy options. Furthermore, both research teams and participants agreed that despite considerable efforts, most models were not sufficiently user-friendly and transparent for being accessed in an IA focus group. With that background, some methodological conclusions are drawn about the inclusion of the computer models in the deliberation process. Furthermore, some suggestions are made about how given models should be adapted and new ones developed in order to be helpful for participatory IA.

Effective application of monitoring information: the case of San Francisco Bay

The San Francisco Estuary Regional Monitoring Program (RMP) for Trace Substances is an innovative partnership among a regulatory agency, more than 70 regulated entities, and an independent scientific organization. The institutional arrangement behind the RMP has made the regulatory system increasingly responsive to emerging management needs, particularly with regard to the development of total maximum daily loads and ecosystem impairment assessment. Through multi-agency partnerships within and outside the RMP institutional structure, major information gaps for several pollutants of concern have been narrowed, resulting in a successful consensus-based regulatory approach to managing copper and nickel mass inputs into the Estuary. Short-term research efforts, based upon monitoring results, helped identify the most cost-effective control and remediation options for various bioaccumulative substances. Additionally, adaptive changes to the monitoring program documented the existence of widespread aquatic toxicity in the Estuary that is apparently due to pesticide runoff from agricultural and urban areas. One of the most important contributions of this collaborative monitoring program is the deliberate and systematic adjustment of management and research questions that serve to influence and add relevance to the overall research agenda related to San Francisco Estuary ecosystem assessment.     

Environmental impact assessment (EIA) as collaborative learning process

A collaborative problem-solving approach was applied to environmental impact assessment of regional waste management strategy in Pirkanmaa, Finland. Various actors—interest groups, authorities, and experts—were invited to engage in joint fact finding and to exchange their views on the goals of alternative waste management strategies. The experiences of these encounters suggest that collaborative EIA can serve as a learning and civic discovery process where people can act together and find new solutions. During the process, the participants were able to reflect on their preferences and factual beliefs and to create a previously unconsidered waste management strategy that most parties found acceptable. The potential for learning and finding mutually acceptable solutions depended, however, on the legitimacy and institutional settings of the process: to what extent different perspectives were considered in the process, not only included, and how EIA was connected to a political decision-making process.     

The siting puzzle: Balancing economic and environmental gains and losses

Traditional approaches to the siting of potentially hazardous but regionally necessary facilities are often ineffective and lead to drawn-out legal disputes ultimately satisfactory to none of the parties. Research at MIT over the last decade has indicated five factors that may solve the siting puzzle. Application of these principles do not guarantee that a decision will not be disputed but may enhance the possibility of a wise and durable agreement.

Comparing the quality of draft environmental impact statements by agencies in the United States since 1998 to 2004

Since the creation of the National Environmental Policy Act in 1970, the United States has required the Environmental Protection Agency (EPA) to rate draft environmental statements (DEISs) for both information adequacy and the impact of the preferred alternative on the environment. In a previous study by Tzoumis and Finegold (2000), these ratings were found to be declining from 1970 to 1997. This current study investigates if that trend continued from 1998 to 2004. In addition, the top producing agencies (the Forest Service, the Federal Highway Administration, Army Corp of Engineers, and the Bureau of Land Management) are compared for the achievement of DEIS ratings. The results show that when the ratings are disaggregated for these agencies, the results indicate that there continues to be weak performance. The DEISs continue to have insufficient and sometimes inadequate information. Agencies continue to propose projects that have environmental concerns and sometimes objections. The agencies have some similarities in not being able to achieve the highest ratings on a consistent basis over time. However, more disturbing is the profile of agencies that have episodic peaks of achieving the lowest ratings. Conclusions and recommendations are focused on the agencies who submit that DEISs and EPA. One major conclusion is to better track the ratings and make them collectively available for the public. Agencies are encouraged to develop a best management practice in preparing DEISs to promote agency learning.     

Regulating Water Quantity and Quality in Irrigated Agriculture: Learning by Investing under Asymmetric Information

An input-based incentive approach for controlling an agricultural non-point source pollution problem is developed. A regulatory agency designs a tax scheme and an investment policy to increase its informational base, in order to obtain the desirable water use and emissions for a set of agricultural producers whose individual water use and emissions cannot be observed without costly monitoring. The agency invests in order to increase observability of water use and emissions, and taxes the observed variables. Learning effects enhance the process of acquiring information about the individual producers' behavior. The optimal tax scheme and the cost minimizing monitoring program are determined.

HIA, the next step: Defining models and roles

If HIA is to be an effective instrument for optimising health interests in the policy making process it has to recognise the different contests in which policy is made and the relevance of both technical rationality and political rationality. Policy making may adopt a rational perspective in which there is a systematic and orderly progression from problem formulation to solution or a network perspective in which there are multiple interdependencies, extensive negotiation and compromise, and the steps from problem to formulation are not followed sequentially or in any particular order. Policy problems may be simple with clear causal pathways and responsibilities or complex with unclear causal pathways and disputed responsibilities. Network analysis is required to show which stakeholders are involved, their support for health issues and the degree of consensus.From this analysis three models of HIA emerge. The first is the phases model which is fitted to simple problems and a rational perspective of policymaking. This model involves following structured steps. The second model is the rounds (Echternach) model that is fitted to complex problems and a network perspective of policymaking. This model is dynamic and concentrates on network solutions taking these steps in no particular order. The final model is the “garbage can” model fitted to contexts which combine simple and complex problems. In this model HIA functions as a problem solver and signpost keeping all possible solutions and stakeholders in play and allowing solutions to emerge over time. HIA models should be the beginning rather than the conclusion of discussion the worlds of HIA and policymaking.     

Performance of poly(vinyl alcohol) gel columns on the ion chromatographic determination of perchlorate in fertilizers

Interest in possible sources of perchlorate (ClO4) that could lead to environmental release has been heightened since the Environmental Protection Agency placed this anion on its Contaminant Candidate List for drinking water. Although recent investigations have suggested that fertilizers are minor contributors to environmental perchlorate contamination overall, there is still interest in screening commercial products for possible contamination and quantitating perchlorate when it is found. Ion chromatography (IC) has been used for this application owing to its speed, low detection limits, widespread availability, and moderate ruggedness relative to other techniques. However, fertilizer matrixes complicate the IC analysis relative to potable water matrixes. In this study, the performance of poly(vinyl alcohol) gel resin IC columns (100 mm and 150 mm) was evaluated for fertilizer matrixes using method EPA/600/R-01/026. The NaOH eluent included an organic salt, sodium 4-cyanophenoxide. Detection was by suppressed conductivity. A set of 55 different field samples representing 48 products and previously used by the EPA to assess occurrence of perchlorate in fertilizers (EPA/600/R-01/049) was reanalyzed on the 150 mm column. The 100 mm column was used to further investigate the positive hits. Both columns gave satisfactory performance in fertilizer matrixes, with spike recoveries (+/- 15%), assured reporting levels (0.5-225 microg g(-1) except for one at 1,000 microg g(-1)), accuracy (relative error < 30% always and most < 15%), and precision [injection-to-injection reproducibility < 3% relative standard deviation (RSD)] comparable to those reported in other studies. Performance did not vary substantially between column lengths. Lastly, the results of this investigation provided further evidence in support of the conclusions that had been reached previously by the EPA on the occurrence of perchlorate in fertilizers.     

Project risk and appeals in U.S. Forest Service planning

The National Environmental Policy Act (NEPA) requires U.S. Forest Service planning processes to be conducted by interdisciplinary teams of resource specialists to analyze and disclose the likely environmental impacts of proposed natural resource management actions on Forest Service lands. Multiple challenges associated with these processes have been a source of frustration for the agency. One of these challenges involves administrative appeals through which public entities can challenge a Forest Service decision following a NEPA process. These appeals instigate an internal review process and can result in an affirmation of the Forest Service decision, a reversal of that decision, or additional work that re-initiates all or part of the NEPA process. We examine the best predictors of appeals and their outcomes on a representative sample of 489 Forest Service NEPA processes that were decided between 2007 and 2009. While certain factors associated with pre-existing social contexts (such as a history of controversy) or pre-determined elements of a proposed action (such as the extraction of forest products) predispose certain processes to a higher risk of appeals, other practices and process-related strategies within the control of the agency also appear to bear meaningful influence on the occurrence of appeals and their outcomes. Appeals and their outcomes were most strongly related to programmatic, structural (turnover of personnel in particular), and relationship risks (both internal and external) within the processes, suggesting the need for greater focus within the agency on cultivating positive internal and external relationships to manage the risk of appeals.     

The impact of stormwater treatment areas and agricultural best management practices on water quality in the Everglades Protection Area

Half of the original Everglades system has been lost to drainage and development. What remains is included within the boundaries of the Everglades Protection Area (EPA), comprised of three Water Conservation Areas (WCAs) and Everglades National Park (Park). Inflows to the EPA contain elevated nutrient concentrations. Best management practices (BMPs) were implemented and six large wetlands called stormwater treatment areas (STAs) were constructed to improve water quality. We analyzed water quality in the WCAs and Park and performed an economic analysis of the STAs to remove nutrients from EPA inflows. In general, nutrient concentrations in all WCAs were higher during the pre-STA period than after the STAs became operational. In WCA2 and the Park, total phosphorus (TP) trends showed more negative slopes prior, as compared to after, the STAs became operational. These results suggest that BMPs lead to large initial decreases in nutrient export resulting in improved downstream water quality. A preliminary economic analysis shows that operation and management of the STAs are complicated and cost intensive. Comparing the cost of phosphorus (P) removal from water entering the EPA using BMPs and STAs may not currently be viable. BMPs prevent P from being applied to, or leaving from agricultural fields while STAs remove P from stormwater. We expect nutrient concentrations in water flowing into and out of the STAs to decline as both BMPs and STAs become more effective. We suggest an economic analysis of BMPs, STAs, and other potential approaches to determine the most cost-effective methods to reduce nutrient concentrations and related stressors affecting the Everglades.     

A nationally consistent framework for identifying interstate waters with applications for the national listing of fish advisories

A 1988 survey, funded by the US Environmental Protection Agency (EPA) and conducted by the American Fisheries Society, identified the need to standardize the approaches for evaluating risks and developing fish consumption advisories that are comparable across different jurisdictions. A major tool for evaluating the progress in developing such nationally consistent information is EPA??s web-based National Listing of Fish Advisories (NLFA) database, which has archived fish advisory information since 1993. The NLFA comprises both a database and Geographic Information System mapping components that are implemented using the National Hydrography Dataset (NHD). EPA and the US Geological Survey have developed an enhanced NHD product (NHDPlus) that is applied to define an interstate waters framework for the conterminous USA. This NHDPlus-based framework provides an efficient watershed-oriented approach for identifying interstate advisories from NLFA. We provide summaries of (1) the degree of consistency documented for inland waters where states have issued advisories for shared interstate NHD reaches and (2) the patterns for interstate advisories organized according to the ecoregions developed for EPA??s Wadeable Streams Assessment. Approaches are also discussed for addressing interstate consistency issues for fish advisories in coastal waters making use of the NHDPlus combined with other nationally consistent frameworks, such as the 12-digit hydrologic unit code subwatersheds in the Watershed Boundary Dataset. Probability survey methods are recommended as a way to promote increased interjurisdictional consistency in the development of the monitoring and risk assessment conclusions reflected in NLFA, as well as in other EPA water quality-based programs.
