Water resource issues are a special concern in the development of conventional oil and gas and coalbed natural gas (CBNG) in the Powder River Basin, Atlantic Rim, and Pinedale areas of Wyoming. To date, the APD NEPA analysis has been a very time-consuming process using the data and analysis tools available for assessing effects of energy development upon soil and water resources.
This project is the third phase of a multi-year, three-phase research and development project under an Assistance Agreement between BLM and WyGISC. Matching funding committed to this phase of the project includes $26,000 from the University of Wyoming, $14,000 from BLM, and an allocation of $46,100 from DOE. This project involves the research and development of an enhanced version of the U.S. Environmental Protection Agency’s Basins 3 software package that incorporates available high-resolution, 1:24,000-scale watershed and hydrographic geospatial datasets. It incorporates a link with 1:24,00-scale soils geospatial data and associated databases (soil properties and interpretations) and the development of a standard GIS (geographic information system) protocol for use of the package in APD environmental analysis and Water Management Plan (WMP) preparation/evaluation.
Results
WyGISC delivered Phase I and II products to BLM in August 2005. Further enhancement of these products and development of additional functionality in the toolkit is underway in this third phase of product development. A beta test of the toolkit has been completed for the Fortification Creek sub-basin (of the Powder River Basin in Wyoming) in support of the oil and gas environmental impact statement for the subject sub-basin. Outputs of the toolkit analysis will be incorporated in the associated National Environmental Policy Act (NEPA) analysis.
Benefits
Utilization of models in support of decision making provides resource managers with a defensible mechanism for resource management. Spatially distributed models that can compute and model for runoff, erosion, and water quality at these different scales can assist resource managers in addressing these spatial complexities, validating sound management decisions, and making more timely permitting decisions. Money and time will be saved by the Federal and State regulatory agencies as well as the industry, and greater effort can be allocated to preservation or conservation of the resources on these lands.
Summary
Upon completion of Phase III, this project will deliver a cost-effective, multi-resource GIS analysis package equipped with the best available GIS datasets and associated navigation, query, and analysis tools. It will provide 1) a more rapid, comprehensive, and accurate analysis of water, watershed, and soils resource impacts (e.g., erosion, runoff, sedimentation); 2) a data archive platform; 3) a standard resource analysis protocol that will not only speed the environmental analysis process but will also provide a consistent, well-documented protocol that will aid BLM in more quickly evaluating WMPs required as part of APDs; and 4) a means to accumulate analysis results from the sub-watershed to sub-basin scale so that larger-scale cumulative water resource impact analysis and monitoring is possible. The enhanced Basins 3 package will be public domain and available to land management and regulatory agencies and industry as well. This enhanced Basins 3 package will serve the same function in other areas of the State as high-resolution soils datasets become available.
