<br />The purposes of this report are: (1) To describe the program objectives
<br />of the Yampa River basin assessment, and (2) to outline the methodologies in
<br />carrying out the Phase-II investigations, The project is coordinating field
<br />activities and interpretative analyses with other related studies, both within
<br />and outside the U.S. Geol.ogical Survey. This work-plan report serves as an
<br />information guide in implementing the proposed Phase-II work tasks of the
<br />assessment.
<br />
<br />During 1975, a Regional Residuals-management study (referred to in this
<br />report as the reslduals-,management analysis) has been performed by the U.S.
<br />Geological Survey (1976). This research-oriented analysis seeks to define the
<br />r.elationships between water use; the prices of raw materials, and the costs of
<br />modifying residuals to meet environmental standards. Residua,ls management
<br />identifies and evaluates strategies for reducing or modifying discharge of
<br />waste materials in order to meet enVironmental-qual ity goals. The residuals-
<br />management approach concentrates on coal mining and conversion to electricity
<br />or gas products, The study, which deals with plant-level processes, provides
<br />an analytical bas is to assess the impact of coal-resource development on re-
<br />gional water resources and environmental quality. Certain components of this
<br />first-phase residuals-management analysis will provide input to the Yampa
<br />River basin' assessment,
<br />
<br />Both projects presently are enter ing second phases of thei r respective
<br />studies, This project work plan describes s.everal of the coordinated work
<br />a~tivities of the two projects.
