Impact Of Carb's Tailpipe Emission Standard Policy On Co2 Reduction Among The Us States, Jaewon Lim, Doohwan Won

Public Policy and Leadership Faculty Publications

U.S.Environmental Protection Agency (EPA) set the nationwide emission standard policy, but each state in the U.S. has an option to follow the higher emission standard policy set by CARB (California Air Resources Board) in 2004. There are 14 “CARB states” that follow California’s more restrictive standards. The purpose of this paper is to examine the impact of CARB’s tailpipe emission standard policy. Using the panel dataset for 49 U.S. states over a 28-year study period (1987–2015), this paper found the long-term policy effect in reducing CO2 emission from CARB’s tailpipe standard, and its long-run effect is 5.4 times higher than …

An Examination Of Rural Residents’ Perceptions Of Environmental Activities At The Nevada Test Site: Results Of A Mail Questionnaire 2008 – 2009, Helen R. Neill

Public Policy and Leadership Faculty Publications

Purpose:

Given the U.S. DOE's Environmental Management activities at the Nevada Test Site, what matters to rural residents living nearby?

DOE provided a grant to the University of Nevada, Las Vegas to conduct a questionnaire and analyses.

Rural Communities And Awareness Of Doe Environmental Management Programs At The Nevada Test Site: Do Outreach Efforts Matter?, Helen R. Neill, K. K. Snyder, Janet Ward

Public Policy and Leadership Faculty Publications

Are residents living in communities around the Nevada Test Site aware of environmental remediation activities and do outreach efforts contribute to awareness? Through a U.S. Department of Energy (DOE) grant, the University of Nevada, Las Vegas administered a mail questionnaire to 14,083 residents and received 1,721 responses. Approximately 90% of the respondents reported awareness of past nuclear tests at the Nevada Test Site; 63% reported awareness of low-level radioactive waste disposal at the site; and 41% are aware that the Yucca Mountain Project for high level waste disposal is part of the Office of Civilian Radioactive Waste Management and not …

Plant Recruitment In A Northern Arizona Ponderosa Pine Forest: Testing Seed- And Leaf Litter- Limitation Hypotheses, Scott R. Abella

Public Policy and Leadership Faculty Publications

Seed availability and leaf litter limit plant establishment in some ecosystems. To evaluate the hypothesis that these factors limit understory plant recruitment in Pinus ponderosa forests, I conducted a seeding and litter removal experiment at six thinned sites in the Fort Valley Experimental Forest, northern Arizona. Experimental seeding of four native species (Penstemon virgatus, Erigeron formosissimus, Elymus elymoides, and Festuca arizonica) and raking of litter occurred in 2005. Seeding resulted in a substantial recruitment of 14 to 103 seedlings/m2 (1 to 10/ft2) one month after seeding for two species (P. virgatus and E. elymoides), but these densities subsequently declined by …

Uncertainty, Climate Change And Nuclear Power, David M. Hassenzahl

Public Policy and Leadership Faculty Publications

Long time-horizon environmental risks with potential for global impacts have increased in visibility over the past several decades. Such issues as climate change, the nuclear fuel cycle, persistent synthetic chemicals, and stratospheric ozone depletion share some characteristics, including intergenerational impacts, strongly decoupled incidence of risks and benefits, substantial decision stakes and extreme uncertainty. What is not well understood are the similarities and differences among sources and implications of uncertainty among these global environmental threats, especially those associate with current and future human behavior. This describes the uncertainties associated with managing two global concerns: the nuclear (fission) fuel cycle and anthropogenic …

Converting Low-Level Mixed Waste Into Transuranic Waste For Geologic Disposal At Wipp: A Cost Analysis, Helen R. Neill, Robert H. Neill

Public Policy and Leadership Faculty Publications

The Department of Energy (DOE) has approximately 43,000 cubic meters of mixed-low-level waste (MLLW) with alpha emitting concentrations of 10 to 100 nanocuries per gram (nCi/g) generated from the nations defense programs requiring radioactive waste disposal [1]. DOE has decided to commingle MLLW containers with transuranic (TRU) waste containers in larger containers such that the average concentration in the larger container would qualify as TRU waste for deep geologic disposal at the Waste Isolation Pilot Plant (WIPP). Since Congress has exempted the WIPP mixed TRU waste from the Resource Conservation and Recovery Act (RCRA) [2] requirement to treat the waste …

Perspectives On Economic Analyses For High Level Waste Disposal, Helen R. Neill, Robert H. Neill

Public Policy and Leadership Faculty Publications

There are both internal and external pressures on the U.S. Department of Energy (DOE) to reduce costs of disposal and still maintain radiation protection to both present and future generations. The question arises whether both of these goals are attainable.

What Does Smart Growth Mean For Housing?, Karen A. Danielsen, Robert E. Lang, William Fulton

Public Policy and Leadership Faculty Publications

Barely noticed amid the returns from the 1998 midterm elections was a quiet revolution that goes to the heart of how and where Americans live. While most news accounts focused on the high-profile candidate elections, voters across the nation-in Democratic and Republican areas alike-approved more than 160 state and local ballot measures intended to preserve open space and limit urban sprawl.

The coalition forming around the idea of limiting sprawl includes environmentalists, farmers, big-city mayors, and some developers. But perhaps most important, the so-called "smart growth" movement also includes many suburban voters who are fed up with growth. For example, …

Describing The Elephant: Multiple Perspectives In New York City's Watershed Protection Conflict, Krystyna Anne Stave

Public Policy and Leadership Faculty Publications

New York City's efforts to avoid filtration mandated by the 1986 Safe Drinking Water Act Amendments and the 1989 Surface Water Treatment Rule have generated considerable controversy. Since the conflict began in 1990, a spectrum of stakeholder groups has emerged, representing land owners, sport fishermen, businesses, environmental groups, developers, and watershed communities. What was originally defined by New York City water supply managers as a scientific problem--identifying sources of water quality degradation and preventing contaminants from entering the water supply system--now has broadened to include a diverse set of social and economic issues as well.

Resource Use Conflict In New York City's Catskill Watersheds: A Case For Expanding The Scope Of Water Resource Management, Krystyna Anne Stave

Public Policy and Leadership Faculty Publications

In New York City's water supply watersheds, controversy over water quality protection underscores both the need to expand the scope of water resource management and the challenges to doing so. This paper describes the response of watershed residents to !'Jew York City's efforts to avoid filtration mandated by the 1986 Safe Drinking Water Act Amendments and 1989 Surface Water Treatment Rule. The emergence of a spectrum of stakeholder groups representing land owners, sport fishermen, businesses, environmental groups and local communities has brought social and economic issues not previously part of the City's water management program to the center of the …

Using Gis To Identify Critical Areas For Water Quality Protection In New York City's Water Supply System, Paul K. Barten, Krystyna Anne Stave

Public Policy and Leadership Faculty Publications

The protection of water quality at its source — the watershed — recognizes that minimizing land use impacts and allowing natural processes to provide in situ biological treatment can complement conventional engineering methods. In contrast to the enormous costs projected for drinking water filtration, the judicious application of watershed management principles and practices is a way to balance the needs of people with the capacity of the natural resource base over time. This paper describes the development and initial application of a geographic information system (GIS) to a ortion of New York City's 2,000 square mile water supply system, the …
