The <br />analytical results presented herein are consistent with previously reported data. <br />A summary of the 1998 precipitation data for the site, with a comparison to the monthly and <br />annual values for 1995 through 1997, is also enclosed. As you are aware, above normal rainfall <br />was experienced at the Cresson Project during late July and August. In fact, a total of 16.03 inches <br />of rainfall were received during these two months. The average precipitation received in July and <br />August of 1995, ]996, and 1997 was 6.51 inches. The most intense rainfall occurred between July <br />24 and August 9, 1998. During a 24-hour period on July 24 and July 25, measured precipitation <br />totaled 3.4 inches. This is only slightly below the 100-year, 24-hour precipitation event for this <br />area of 3.5 inches and substantially in excess of the 10-year, 24- hour event. CC&V also recorded <br />about 2.0 inches of precipitation during a one hour period on July 28, 1998. The heavy rainfall <br />received in July and August resulted in increased flows at many monitoring locations at the <br />Cresson Project during August, September, and October 1998, However, the valley leach facility <br />continued to function as designed and constructed. <br />Please do not hesitate to contact me at 7] 9-689-4041, if you have any questions or comments. <br />Sincerely, <br />Scott A. Lewis <br />Manager, Environmental Affairs <br />
