Summary Report #7 and Quarterly Data Report #7 cover the seventh quarter of exploration and environmental data for the Environmental Baseline Program of Tract C-b. These reports specifically cover the spring quarter of March 1975 through May 1976. Quarterly Data Report #7 consists of three volumes of the comprehensive data collected for Tract C-b and submitted to the Area Oil Shale Supervisor in Grand Junction on July 15, 1976. The purpose of Summary Report #7 is to provide the reader with a general overview of the information included in Quarterly Data Report #7. For a complete review of tract activities to date, reports from all quarters must be consulted. Parties interested in the project can review these volumes by contacting the Area Oil Shale Supervisor's Office. For ready reference, the reader is reminded that both outline and section numbering in summary and quarterly data reports are identical.
