Canadian discrete water quality data and daily streamflow records were evaluated using the Weighted Regression on Time, Discharge, and Seasons (WRTDS) model implemented with the EGRET R package (Hirsch et al. 2010, Hirsch and De Cicco 2015). Models were used to estimate loads of solutes and evaluate trends for three constituents of interest (selenium, nitrate, and sulfate). Six models were generated; one model for each of the three constituents of interest, in each of the two major tributaries to Lake Koocanusa: the Kootenay River at Fenwick (BC08NG0009), and the Elk River above Highway 93 Near Elko (BC08NK0003). Data were obtained by downloading data from the British Columbia Water Tool (https://kwt.bcwatertool.ca/surface-water-quality,...
Costs and benefits of building energy efficiency are estimated as a means of reducing greenhouse gas emissions in Pittsburgh, PA and Austin, TX. The analysis includes electricity and natural gas consumption, covering 75% of building energy consumption in Pittsburgh and 85% in Austin. Two policy objectives were evaluated: maximize GHG reductions given initial budget constraints or maximize social savings given target GHG reductions. This approach evaluates the trade-offs between three primary and often conflicting program design parameters: initial capital constraints, social savings, and GHG reductions. Results suggest uncertainty in local stocks, demands, and efficiency significantly impacts anticipated outcomes....
Coal mining is one of the most important causes of environmental pollution, as large quantities of coal dust particles are emitted. Colombia-South America has large natural coal reserves and "El Cerrejón" is the world's largest open-cast mine located in the northern department of Guajira. The aim of the present study was to evaluate genotoxic effects in a population exposed to coal residues from the open-cast mine "El Cerrejón". 100 exposed workers and 100 non-exposed control individuals were included in this study. The exposed group was divided according to different mining area activities: (i). Transport of extracted coal, (ii). Equipment field maintenance, (iii). Coal stripping and, (iv). Coal embarking.

All mining lease boundaries found in the Powder River Basin. This data layer has many overlapping polygon features and is thus more applicable if used as Arc/Info regions. Each region is attributed relating to the name of the coal mine utilizing the leased area. The data layer was originally produced by the Bureau of Land Management and distributed in an ASCII text format which was then converted into a GIS layer.

Coal croplines found in the Powder River Basin, 1:24000 scale. Coal cropline is the exposed coal seam due to erosion and tectonics. Each linear feature is attributed with reference to the name of the coal seam that is exposed. The data were originally produced by digitizing photointerpreted coal cropline features off of 1:24,000 USGS quadrangles.

Clinker regions found in the Powder River Basin, 1:24000-scale. Clinker is baked and fused geologic material generated during the combustion of a coal seam. Each area is attributed with reference to the name of the coal seam responsible for producing the clinker. The data were originally produced by digitizing photointerpreted clinker polygons off of 1:24,000 USGS quadrangles.

This data set was developed from a Bureau of Land Management database containing information on coal thickness from core samples, converted into a spatial database using kriging techniques. The data set covers the Little Thunder Creek watershed in the Powder River Basin, Wyoming. Each polygon is attributed with reference to a range of thickness describing the coal seam (measured in feet).
Models that treat innovations to the price of energy as predetermined with respect to U.S. macroeconomic aggregates are widely used in the literature. For example, it is common to order energy prices first in recursively identified VAR models of the transmission of energy price shocks. Because exactly identifying assumptions are inherently untestable, this approach in practice has required an act of faith in the empirical plausibility of the delay restriction used for identification. An alternative view that would invalidate such models is that energy prices respond instantaneously to macroeconomic news, implying that energy prices should be ordered last in recursively identified VAR models. In this paper, we propose...
