A geospatial data catalog and metadata management tools for the U.S. Environmental Protection Agency’s Western Ecology Division

Creator:: Bradford, David L.
Abstract:: The EPA’s Western Ecology Division (WED) had been accumulating geographic information system (GIS) data files for up to 20 years. There was no index or catalog for these files; locating data became more difficult over time. More that 4 Tb of data existed on numerous disk volumes in hundreds of...

Modeling the Environmental Protection Agency's level IV ecoregions within the Klamath Mountains of southern Oregon and northern California

Creator:: Zanger, Christopher
Abstract:: Ecoregions are regions of relative homogeneity with respect to specific ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing awareness that effective management of environmental resources must be undertaken with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial framework for assessing, managing, and monitoring ecosystems that...

Effects of timing and duration of flooding on phosphorus release in four restored wetlands around Agency and Upper Klamath Lakes, Oregon

Creator:: Stevens, Carla J.
Abstract:: Upper Klamath Lake (UKL) and Agency Lake in south-central Oregon are hypereutrophic due to phosphorus (P) loading from both geologic and agricultural sources in the watershed. Restoring historic lake-fringe wetlands to provide P sinks around the lakes has been accepted as a favorable means of reducing lake P levels and...

Judicial deference and its potential effect on agency science and natural resource management

Creator:: Grisa, Amanda Marie Schenk
Abstract:: The USDA Forest Services' actions have come under greater scrutiny by a public that has become increasingly concerned with the legality of their actions. Often, challenges involve the quality of science used in the decision-making. Congress has mandated that the agency use the "best available science" in its decision making...

Evaluation of cathodic protection in reinforced concrete bridges

Creator:: Abooameri, Farid
Abstract:: Steel corrosion in reinforced concrete is a major concern to transportation agencies nationwide because of the expenses incurred for repair and ultimate shortening of bridge life. Cathodic protection (CP), as a remedy, has been applied to reinforced bridges in the US since 1974. However, application of this technique is largely...

Prediction of Initial Mixing for Municipal Ocean Discharges

Creator:: Teeter, Allan M. and Baumgartner, D. J.
Abstract:: The purpose of this report is to present procedures by which applicants and reviewers can calculate initial dilution and describe the zone of initial dilution surrounding the discharge site. These calculations would be required under regulations proposed by the U.S. Environmental Protection Agency on April 25, 1978 (1) implementing section...

How environmental regulations affect productivity of U.S. and Mexican primary iron & steel and aluminum industries

Creator:: Hackenbruck, Satenik
Abstract:: Many economists believe that the slowdown of the productivity growth rates in the U.S. economy in early 1970's was a consequence of the increased level of environmental regulations. The main reason presented in support of this argument is that increased environmental regulations impose an additional burden to the firms, thus...

Evaluating the presence of radium-226 in soil surrounding a coal-fired power plant using the multi-agency radiation survey and site investigation manual (MARSSIM)

Creator:: Herring, Thomas A. (Thomas Andrew)
Abstract:: Coal-fired power plants constitute a significant source of energy production for the United States, and are projected to do so for decades to come. Most of the scrutiny coal-fired power plants receive is in the form of environmental concerns regarding green house gas emissions of carbon dioxide, sulfur dioxide, and...
