Mineral Environmental Assessment at Regional Scale
The Mineral Resources Program has successfully completed, and continues to
implement, various mineral-environmental assessments at the site, watershed
and regional scale. These assessments have been able to collect extensive new
geoenvironmental data for the areas in question. However, further method development
is needed to conduct a national-scale Mineral Environmental Assessment (MEA) that
optimally integrates information developed in a Quantitative Mineral Resource Assessment (QMRA) and
that, because of the scale and expense involved, cannot be heavily based on newly
collected geoenvironmental data.
In order to establish the best methodologies for the national MEA, it is advantageous to
carry out a prototype MEA of a large region of the U.S. for which a quantitative mineral
resource assessment has been completed. The prototype assessment would ideally be
done within a 2-year framework, so that lessons learned from its implementation can be
integrated into the planning process for the formal national QMRA-MEA to be started in
Fiscal Year 2013.
The primary objective of this task will be to plan and implement a prototype qualitative mineral environmental assessment (MEA) on a selected large region of the Nation for which a quantitative mineral resource assessment (QMRA) has been completed. This GIS-based prototype assessment will:
- test a variety of methodologies,
- identify data gaps,
- evaluate approaches for presenting the results, and
- evaluate the extent to which a more rigorous, less qualitative approach can be applied to the MEA.
Subtasks to accomplish these objectives are:
Statement of Work
- Write up methodologies for use in national MEA
- Evaluate how results from multiple regions can be scaled up for depiction on national
scale maps likely to be produced as part of the National QMRA
