The purpose of this document is to describe the Environmental Plan which was designed to assess the environmental aspects of Equity's in situ oil shale project. Although the project is of pilot scale, the plan was designed so that the data can be used to assess the potential environmental impact of possible future commercial development. The project and the environmentally oriented work to be done under the project are discussed. The section has been segmented such that for each subprogram, i.e., Air Resources, Water Resources and Aquatic Biology, the program background, purpose, objectives and research needs are presented. Also included in the program discussions is a presentation of the applicable Federal, state and local regulatory requirements. Another section details the environmental mitigation and monitoring reporting requirements. The methodologies, sampling techniques, sampling frequency, and the quality assurance/quality control procedures that have been implemented for each environmental activity are also detailed.
