<br />1992, 1993, 1994 AHR Review <br />Bear Coal Company <br />April 19, 1995 <br />Page 2 <br />required to be collected between May and November. The results of <br />this monitoring should appear in the 1994 AHR. <br />The monitoring plan for the 1993 AHR was on page 2.04-30b, revised <br />August 4, 1993. The monitoring plan for the 1994 AHR is also on <br />page 2.04-30b, revised March 4, 1994. <br />1. An annual full suite sample is required for alluvial wells AA1 <br />and AA3, and these were taken on December 20, 1993 (1993 AHR) <br />and January 2, 1995 (1994 AHR). The full suite sample should <br />be taken during the monitoring year, and at approximately the <br />same time period as the year before. <br />A visual inspection of the sample for oil and grease is also <br />required and this information was not included for the 1992, <br />1993, or 1994 AHR. In addition, Total Dissolved Solids (TDS) <br />were not analyzed for the samples collected for the 1994 AHR. <br />Please provide this information or explain why it is not <br />available. <br />2. Quarterly samples are also required for the alluvial wells and <br />include only the collection of water level and field <br />parameters. These data were collected for all quarters during <br />1993 and 1994; however, a visual inspection of the sample for <br />oil and grease is also required, and not included for the <br />1992, 1993, or 1994 AHR. Please provide this information or <br />explain why it is not available. <br />3. Monthly flow and field parameters are required for the upper <br />and lower french drains. Flow for three months, April, May, <br />and August, is noted in the text of the 1993 AHR for the upper <br />french drain. The table indicates that attempts were made to <br />collect samples on October 8, November 11, and December 23, <br />1993, but there was no flow. Assuming the drain was installed <br />in March or April, please explain why field parameters were <br />not collected when flow was observed in April, May, and August <br />and why there are no data for June, July, and September. <br />In 1994, the upper drain was checked every month and only <br />found to be flowing during March, April, and May. Field <br />parameters were also collected. <br />Temperature should also be included in the required list of <br />parameters for the upper and lower french drains. Please <br />provide a revised permit page. <br />4. Sediment Pond 004 did not discharge during the 3rd and 4th <br />quarters of 1993. The pond did discharge during the 1st <br />
