DMG Permit C-81-071 <br />Dear Mr. Gorham: <br />Enclosed are two copies of the 1994 Annual Hydrology Report for the above- <br />referenced permit. The report contains tables, figures, and a discussion of the <br />results of the hydrologic monitoring for water year 1994. Also attached is a revised, <br />complete data listing of all data collected in 1994 and 1995. No significant <br />unpredicted impacts have been observed to date. <br />I apologize for the delay in providing the report. It was CYCC's understanding, <br />based upon conversations between yourself and Mr. Karl Koehler, that submitting <br />the report at the same time as the 1995 water year report was acceptable. CYCC <br />encountered problems in moving our water quality database from a mainframe to a <br />PC. Most of the problems have been corrected; however, some additional <br />programming will be required and will not be completed until mid-1996. <br />If you have any questions, please contact me. <br />Sincerely, <br />~i ~~~/ i~~Z~ <br />Richard A. Mills <br />Manager, Environmental Affairs <br />Enclosures <br />
