Shelley Ross Saxer (Pepperdine) has posted Managing Water Rights Using Fishing Rights as a Model, forthcoming in Marquette Law Review Vol. 95 (2011). The abstract:
This Article addresses the need to view water rights as licenses subject to government revocation, without just compensation, in the same way that fishing rights are viewed as licenses subject to government management. It focuses specifically on the methods used to address water resource allocation in the Sacramento-San Joaquin River Delta in California, and on fish allocation issues in the Pacific Northwest. It explores property rights in water and fish, particularly in regard to Fifth Amendment takings challenges when government regulations diminish water rights and fishing rights. The Article concludes by recognizing that both water and fish resources should be managed as ecosystems and governed by the public trust doctrine, and rejecting private property rights in either fish or water as a violation of the public trust doctrine, in which public resources are given away to private interests.

I'm proud to announce that today UGA Law Public Interest Fellow David Deganian and the fine folks at GreenLaw published "The Patterns of Pollution: A Report on Demographics and Pollution in Metro Atlanta." They were assisted by the consultants of NewFields LLC (who have also helped us in our work in the Newtown community of Gainesville, Georgia).
From GreenLaw's media release:
The report analyzes publicly available information to identify eight types of air, water, and land pollution points and compares this pollution information with demographic data on people living in the 14-county region. Using cutting edge mapping technology to visually combine these areas, we were able to see an overall pattern across the region indicating that a person’s race, income, and primary language spoken have a strong relationship to his or her distance from pollution.
The report website features an interactive map where you can enter an address in the metro Atlanta area and view pollution points nearby.
This report contains extensive fact-based analysis of the impact of pollution on communities of color in Atlanta, and I think it will be an influential part of environmental justice initiatives in the region for years to come. Land Use Clinic students have been working with David and GreenLaw throughout his fellowship, and it's so exciting to see the work come to fruition in such a palpable way.

During his great guest-blogging stint here in January, it appears that Stephen Miller (Idaho) was also busy finishing his article Building Legal Neighborhoods, which has been accepted for publication by the Harvard Environmental Law Review. The abstract:
Political and legal tools have emerged since the Seventies, and especially in the last two decades, that provide political and legal power to neighborhoods. However, these tools are often used in an ad hoc fashion and there has been scant analysis of how these tools might work together effectively. This article seeks to explore this trend, and further argues that cities consciously overlay these neighborhood legal tools. This approach is referred to in the article as a de facto “legal neighborhood.” This approach does not call for secession of neighborhoods from cities or for the wholesale privatization of public functions, as have others that argue for neighborhood empowerment. Rather, the article asserts that the collective operation of these neighborhood tools is greater than the sum of their parts, providing a method for civic engagement at a level city-wide politicians feel comfortable serving and in which residents feel comfortable participating. The article also provides approaches for linking the neighborhood to city and regional affairs, and a history and theory of the concept of the neighborhood as an argument for the important role and function of neighborhoods in American life.
Looks like a very timely and interesting piece.

David L. Markell (Florida State) has posted Climate Change and the Roles of Land Use and Energy Law: An Introduction, Journal of Land Use & Environmental Law, Vol. 27 (2012). It's the intro to a Symposium issue. The abstract:
The challenges posed by climate change are daunting and have spawned an enormous literature, indeed many literatures. The legal regimes that govern our use of land and energy have already been and will continue to be integral to the effort to devise effective responses. My aim in this introductory essay is to identify and review six aspects of climate change in an effort to capture some of the ferment that now exists as policy makers, scholars, and others wrestle with the challenges that climate change poses for extant legal regimes. I then briefly summarize the articles in this symposium volume.

Patricia Salkin (Albany) has posted a review essay called David L. Callies, Regulating Paradise: Land Use Controls in Hawai’i (2d Ed. 2010) (Book Review), published in The Urban Lawyer, Vol. 43, No. 4, p. 1107, 2011. The abstract:
In 1984, Professor David Callies wrote Regulating Paradise to describe the regulatory scheme in Hawai’i. In 2010, he followed up that book with Regulating Paradise: Land Use Controls in Hawai’i to reexamine the issues as they have developed over the last 25-plus years: housing affordability, the subjects of development agreements, condemnation, defining open space and agricultural lands, takings, cultural sensitivity, environmental assessment, the prevalence of covenanted communities, and redevelopment.
This essay is a review of Professor Callies work which is a must read for anyone involved in land use in Hawaii. What emerges from his work are lingering questions about whether the regulatory scheme has over protected paradise.

Sean F. Nolon (Vermont) has posted another article at the interface of land use and ADR: Do We Need Environmental Mediators? Indigenous Environmental Mediation: Exploring New Models for Resolving Environmental Disputes. The abstract:
According to the best practices of environmental mediation, mediators are professionals who come from outside the community. The conventional wisdom holds that this distance from the parties and the dispute increases the likelihood that the mediator will manage the process in an independent and neutral manner and decrease the likelihood of any substantive bias. Yet, in practice, many environmental mediations go forward without the use of outside mediators relying instead on mediators who come from within the community. While recognized in the theory as an option, the use of community mediators has not received much attention in the scholarship. When looking at disputes involving inside mediators more closely, a pattern of practice emerges that can benefit agencies and individuals in their decisions to employ environmental mediators. This article explores some of the disputes where inside mediators have been used to construct a complementary model to that of the outside model. This complementary model, labeled “indigenous environmental mediation,” relies on mediators who come from the community, instead of outsiders, to help parties improve relationships, ensure compliance with agreements, and advocate that decision making agencies respect stakeholder agreements. This article provides support for the continued use of outside mediators but also suggests a more intentional effort to employ indigenous mediators in environmental disputes.

Hannah Wiseman (Florida State) has posted Fracturing Regulation Applied, Duke Environmental & Policy Law Forum (forthcoming). The abstract:
America has a long history of oil and gas extraction, but a relatively new extraction technique called slickwater hydraulic fracturing has captured the attention of the public, academics, agencies, and politicians. The newly-revived focus on domestic oil and gas — and particularly on fracturing — has tended to center around the adequacy of environmental laws as written. A range of interested parties have questioned whether states, which shoulder the core responsibilities for regulating drilling and fracturing, have adequate regulatory regimes to address an array of potential environmental effects. The focus has tended to be on the text of regulations, however, and not on how regulations operate in practice: How states apply regulations by inspecting sites, noting violations, and enforcing violations when they believe that enforcement is justified. This paper expands the small literature that has emerged in this area, providing a preliminary glimpse into state environmental regulations applied to wells that are drilled and fractured. It briefly explores the types of violations that states have noted so far at fractured wells, the enforcement actions that they have issued in response, and the potential reasons for these patterns. Although much more detailed work will be necessary to accurately pinpoint regulatory patterns, the initial picture suggests a wide array of violations and enforcements associated with a range of potential environmental effects—many benign, but some serious. States have noted a number of substantial issues, from spills to improper maintenance of pits for waste, while others have tended to identify less pressing matters, such as operators’ failure to mow weeds around the wellhead. States’ enforcement responses to these violations also have varied substantially, perhaps due to differing policy directives and wills to enforce, budgetary needs, understaffing, or problems of regulatory capture.
Very interesting thoughts on what is fast becoming the critical issue in energy and environmental law and policy. I take pride in mentioning once again that Hannah was one of our outstanding guest-bloggers last year.

Reed Benson (New Mexico) has posted Public on Paper: The Failure of Law to Protect Public Water Uses in the Western United States, Journal of Rural Law and Policy, Vol. 1, No. 1, 2011. The abstract:
Water conflicts in the western United States increasingly arise from competition between traditional economic uses (especially irrigation, municipal supply and hydropower) and public uses (especially environmental protection and water-based recreation). Western United States water law, based on the prior appropriation doctrine, has always promoted maximizing ‘beneficial use’ of the resource and has effectively protected water allocations for traditional purposes. Public water uses also enjoy some legal protection, but it exists mostly on paper; in practice, neither statutory public interest provisions nor the non-statutory public trust doctrine has been widely effective.
This paper identifies the relevant legal principles and briefly explains how they have failed to protect public water uses in the western United States.

Holly Doremus (Berkeley) has posted Climate Change and the Evolution of Property Rights, University of California Irvine Law Review, Vol. 1 (2012). The abstract:
Climate change will unsettle expectations about both land and water. Those changes will reduce the extent to which existing resource allocations effectively serve societal interests. In the United States, we typically rely on market transactions to adjust property allocations as societal needs and interests change. Markets, however, will not adequately protect the collective, as opposed to the private, interests climate change will put at risk. Changes to underlying property rules will be needed if those interests are to be sustained.
Because current property rules stand in the way of efficient and effective adaptation to climate change, evolution of property law is an important aspect of adaptation. But because property rules are especially sticky, the needed changes will not come easily. Federal courts must play the keystone role because they control the interpretation of key constitutional doctrines. The chief legal impediment to climate adaptation at the moment is federal court resistance to changes in property rules. If that resistance can be softened, state courts and legislatures can, and likely will, make needed adjustments. Federal courts should be careful not to stand in the way of such adjustments, although they also have a role to play in ensuring that the costs of change are fairly distributed.

Jessica Owley (Buffalo) has posted Exacted Conservation Easements: Emerging Concerns with Enforcement, Probate & Property, Vol. 26, No. 1, p. 51, 2012. The abstract:
Enforceability of exacted conservation easements is uncertain. Legislators, activists, and academics did not contemplate the proliferation of exacted conservation easements when enacting, advocating for, and writing about state conservation easement statutes. Despite this early oversight, exaction has become one of the most common ways that conservation easements come into being. Enforceability of exacted conservation easements is a threshold question of analysis for the continued use of the tool. Assessing the validity, and thus legal enforceability, of the exacted conservation easements involves examining the state’s conservation-easement statutes and state servitude law as well as the underlying permit scheme.
This article presents a roadmap for investigating the enforceability of exacted conservation easements and makes three suggestions for improvement. First, states should address exaction in their state conservation-easement acts. Second, drafters should increase the precision and detail of the agreements, acknowledging and explaining the nature of the exaction and the underlying permitting law. Third, to clarify the elements and uses of exacted conservation easements to both agencies and citizens, government agencies that use exacted conservation easements should promulgate regulations related to their use. Such regulations should include ensuring that permit issuers retain third-party right of enforcements. This will keep the permitting agency involved even if it is not the holder of the exacted conservation easement.
Uncertainty in enforceability of exacted conservation easements calls into question their use as a method of land conservation. Furthermore, the questionable validity of exacted conservation easements indicates that the permits relying upon such exactions could be ill advised and potentially in jeopardy.
This accessible piece builds on some of the concerns outlined in her recent Vermont Law Review piece, The Enforceability of Exacted Conservation Easements.

Via Jessica Owley, news of an interesting upcoming conference at Buffalo:
Save The Date and Call for Papers
Wetlands Policy for the Next Generation
26-27 April 2012 at SUNY Buffalo Law School
Buffalo, New York
Beyond Jurisdiction: Wetlands Policy for the Next Generation will bring together academics from law and other fields to join advocates in an exploration of the future of wetlands law and policy from a variety of perspectives (normative, empirical, instrumental, etc.). As is true of many areas of law and social policy, the world of wetlands is inherently political and value-laden—the law is often be a poor means of accomplishing contested social objectives in this area. A debate sparked by U.S. Supreme Court decisions and related federal actions have focused wetlands scholarship and advocacy during the past decade on exploring the parameters of which “waters of the United States” fall under federal jurisdictional. Such concentration has detracted from scholarship and study of many other important issues related to wetlands policy, such as mitigation, the Tulloch rule, nationwide permits, local and state policy developments, international treaty obligations, and other matters. This conference is designed to broaden the focus of exploration and include voices of scholars, activists, scientists, media professionals, and others.
We welcome many voices to this discussion, and invite submissions on any related topic of legal, policy, or additional matters related to wetlands and other jurisdictional waters, including:
· Tulloch/discharge issues
· Ecosystem services
· State and local governance
· Permit processes (including nationwide and regional permits)
· Administration of the Clean Water Act
· International and transnational protections
Accepted papers will be published either in a special journal issue or as a chapter in an academic press book. You are invited to submit a paper abstract or presentation proposal of no more than 400 words by Monday, 13 February 2012 to http://baldycenter.info/cgi-bin/applications/rfp.cgi <http://baldycenter.info/cgi-bin/applications/rfp.cgi> .

Michael Allan Wolf (Florida) has a new book out called The Supreme Court and the Environment: The Reluctant Protector (CQ Press, 2012). Here's the Amazon blurb:
Silent Spring (1962) can arguable be cited as one of the most influential books of the modern era. This book, along with 1960's rampant activism reacting to high-profile ecological calamities, helped create the modern environmental movement. The Supreme Court and the Environment, written by Michael Wolf, discusses one of this movement's most important legacies, namely the body of federal statutory law amassed to fight pollution and conserve natural resources that began with the enactment of the National Environmental Policy Act of 1969. Instead of taking the more traditional route of listing court decisions, The Supreme Court and the Environment puts the actual cases in a subsidiary position, as part of a larger set of documents paired with incisive introductions that illustrate the fascinating and sometimes surprising give-and-take with Congress, federal administrative agencies, state and local governments, environmental organizations and private companies and industry trade groups that have helped define modern environmental policy.
And for a preview, Prof. Wolf has posted the introduction on SSRN. The abstract:
This document contains the Introduction and Contents for The Supreme Court and the Environment: The Reluctant Protector (CQ Press/Sage 2012). When one views the body of modern environmental law — the decisions and the other key documents — the picture that emerges is not one of Supreme Court dominance. In this legal drama, the justices have most often played supporting roles. While we can find the occasional, memorable soliloquy in a Supreme Court majority, concurring, or dissenting opinion, the leading men and women are more likely found in Congress, administrative agencies, state and local legislatures, nongovernmental organizations, private industry, and state and lower federal courts.
What one learns from studying the Supreme Court’s environmental law output is that the justices for the most part seem more concerned about more general issues of deference to administrative agencies, the rules of statutory interpretation, the role of legislative history, the requisites for standing, and the nature of the Takings Clause than the narrow issues of entitlement to a clean environment, the notion of an environmental ethic that underlies written statutes and regulations, and concerns about ecological diversity and other environmental values. When we widen the lens, however, and focus on the other documents that make up essential parts of the story of the Supreme Court and the environment — complaints by litigants, briefs by parties and by friends of the court, oral argument transcripts, the occasional stirring dissent, lower court decisions, presidential signing statements and press conference transcripts, media reports and editorials, and legislative responses to high court decisions — we discover what is often missing in the body of Supreme Court decisions.
Looks fascinating, and is a very original take that situates the cases themselves within a broader context of Supreme Court jurisprudence and goes beyond to the larger networks of actors that shape law.

Yes, more about "fracking", that is, oil and gas extraction through hydraulic fracturing. Erica Levine Powers (SUNY-Albany-Geography and Planning) has published Home Rule Meets State Regulation: Reflections on High-Volume Hydraulic Fracturing for Natural Gas, ABA St. & Loc. L. News (Vol. 35, No. 2, p.1). Here's the opening:
Hydraulic fracturing, or “fracking,” like all mining, is both a local matter impacting community development and environmental quality and a state matter impacting national energy security and regional economic development. Along with the discovery of new sources of natural gas—and methods for its recovery—have come increasing battles over local control and state interests. States have taken diverse positions on fracking, and, building on the experiences of other states, New York is the latest to wrestle with the issue. In the process, New York is defining the roles of local and state government by including an explicit role for local government in environmental review, by public input in the state review process, and through ongoing litigation that will define the rights of New York’s home-rule municipalities to regulate fracking.

Hannah Wiseman (Tulsa, Florida State)--who did some terrific guest-blogging with us last year and is part of the crew over at the Environmental Law Prof Blog--and Francis Gradijan (JD, Texas) have posted Regulation of Shale Gas Development, a white paper from the Center for Global Energy, International Arbitration and Environmental Law, University of Texas School of Law. The abstract:
Development of oil and gas from shale and tight sands formations in the United States is rapidly expanding, enabled in part by slickwater hydraulic fracturing (also called fracing, fracking, or hydrofracking). This boom in unconventional production has introduced new concerns in communities around the country, raising questions about potential impacts to surface and underground water supplies and air quality, for example. Some policymakers and administrators have recently updated laws to address these concerns, while others have attempted to fit evolving technologies and practices within existing frameworks. This white paper, written for the Energy Institute at the University of Texas, explores the environmental laws and regulations that apply to most stages of the oil or gas development process in shales and tight sands, from conducting seismic testing to constructing a well pad, drilling, completing a hydraulic fracture treatment, and storing and disposing of waste. It briefly describes federal regulations, including recently-announced EPA regulatory efforts, but focuses primarily on the states, comparing regulations in sixteen states that apply to most stages of the well development process. The paper's comparison tables show that state regulations in some areas vary substantially, and the paper attempts to connect the potential risks of oil and gas development from shales and tight sands -- which are addressed in another Energy Institute paper by Professor Ian Duncan -- to the regulation. The paper concludes that states should consider modifying certain regulations to address these risks. Some states do not require specific types of blowout prevention, for example -- offering only a narrative standard -- yet well blowouts are an important concern. Furthermore, states should consider whether federal Department of Transportation regulations addressing the movement of fracturing chemicals adequately protect against spills, and whether state casing and cementing regulations protect well integrity during the drilling and fracturing process and into the future. States also must explore better options for disposing of large quantities of new wastes. Finally, the collection of more and better data, including information from baseline and post-production water testing, is essential. With states at the regulatory helm, comparison of public law strategies to address development risks can produce fruitful cross-jurisdictional lessons.
Timely and important.

This article from the L.A. Times discusses recent changes to California's stringent environmental review statute (CEQA) that permit the governor to "fast-track" certain development projects through the review process. The merits of CEQA are certainly subject to debate, with business and development groups claiming the law is a job-killer and environmental groups crediting it with preserving important natural resources. I have not read enough to opine on the merits of CEQA, but if there's one thing I do know it's that giving elected officials discretionary authority to decide what gets fast-tracked and what does not is a recipe for trouble. As the article notes ominously, there are already complaints that only politically-connected parties are qualifying for special treatment.

John R. Nolon (Pace) has posted Land Use for Energy Conservation and Sustainable Development: A New Path Toward Climate Change Mitigation. The abstract:
Land use tools and techniques have impressive potential to reduce energy consumption, improve the economy, and mitigate climate change. This article explores the little understood influence of local land use decision-making on energy conservation and sustainable development and how it can mitigate climate change if properly assisted by the federal and state governments. The construction and use of buildings combined with extensive vehicular travel throughout the nation’s human settlements consume large amounts of energy, and much of that consumption is highly inefficient. By enforcing and enhancing energy codes, encouraging the use of combined heat and power and district energy systems, properly orienting and commissioning buildings, incorporating renewable energy resources, and promoting transit and other methods of reducing vehicle miles travelled, local land use law’s potential to achieve energy conservation and sustainable development can be unlocked. These techniques can be organized at the neighborhood level and aggregated by adopting local Energy Conservation Zoning Districts in neighborhoods where significant energy conservation can be achieved. The article proposes federal and state policies, combining features of both the Coastal Zone Management Act and the Enterprise Zone initiative, that can facilitate local land use initiatives that will shape human settlements and control the built environment as a new path toward energy efficiency and climate change mitigation.
In the footnotes, Prof. Nolon notes that this is part of a trilogy:
FN.1. This article is one of three that examine how local land use law that can be used as an effective strategy to mitigate climate change. See John R. Nolon, The Land Use Stabilization Wedge Strategy: Shifting Gound to Mitigate Climate Change, 34 WM. & MARY ENVTL. L. & POL’Y REV. 1 (2009) [hereinafter Land Use Stablization Wedge] and John R. Nolon, Mitigating Climate Change through Biological Sequestration: Open Space Law Redux, 31 STAN. ENVTL. L.J. (forthcoming Winter 2011) [hereinafter Open Space Law Redux].
This is a great set of articles for anyone interested in the subject from one of the leaders in land use and local environmental law.

From the "You Must Hear This" Dept., we have a really interesting NPR report this morning on attempts by some citizens of the town of Dryden, NY to zone out hydraulic fracturing ("hydrofracking") as a means of removing oil and gas from local shale deposits. The report features commentary on crucial state preemption issues by Eduardo Peñalver (Cornell).
I think siting of hydraulic fracturing operations is a terrific subject for discussion in a Land Use, Environmental or Property law class. I even used a hydraulic fracturing hypothetical on my Property final last Spring to test on inquiry notice and reciprocal servitudes. Focusing on public rather than private land use regulation, this story frames the state and local government issues nicely. Enjoy.

John G. Sprankling (Pacific McGeorge) has posted The Emergence of International Property Law, forthcoming in the North Carolina Law Review. The abstract:
Title to deep seabed minerals, ownership of cultural objects, transferable allowances to emit greenhouse gases, security interests in spacecraft, and rights of indigenous peoples in ancestral lands are all components of a new field: international property law.
Scholars have traditionally viewed property law solely as a national concern. Indeed, the conventional wisdom is that international property law does not exist. But if we ask how international law affects private property, we find a substantial body of international property law that governs the rights of individuals, businesses, and other non-state actors. Some components are well established, while others are still evolving.
This article first examines the antecedents of international property law. It then develops the thesis that this law stems from four main sources: regulation of the global commons; coordination of transboundary property rights; adoption of global policies to prevent specific harms; and protection of human rights. It concludes by analyzing the challenges that arise from the emergence of international property law.
Forty years ago, international environmental law emerged as a new field. Today we stand on the threshold of a similar era in international property law. This article argues that the time has come to recognize international property law as a discrete subject, and thereby promote its coherent evolution in future decades.
