Long <br />Division Director <br />Thank you for your Yearly Impoundment Inspection Report, submitted under your letter of April 9, 2002. <br />The report has been reviewed, and the following adequacy issues have been identified. Please supplement <br />the report with the requested information. <br />Rule 4.05.9(]5) Certified inspection reports required by 4.05.9(14) for all impoundments shall include <br />discussion of~ Rule 4.05.9(15)(6) Existing and required monitoring procedures and instrumentation; The <br />report states that there are no required monitoring procedures or instrumentation. However, quarterly and <br />annual inspections are required and have been accomplished. Please cite monthly and yearly <br />inspections as monitoring procedures. <br />Rule 4.05.9(IS)(c) The depth and elevation of any impounded waters at the time of the certified report; <br />Actual depths of water in the impoundments and elevations of water surfaces were not found in the report. <br />The report does state that the long pond and treatment ponds T-1 and T-2 were full. Depths reported for <br />the long pond and ponds T-1 and T-2 appear to be as-built values rather than depths at the time of <br />inspection. The pictures indicate some water in Pond 9 and the Refuse Pond. Please add the depths and <br />elevation of impounded waters to the report. <br />Rule 4.05.9(15)(d) Existing storage capacity of the impoundment; and As-built storage capacities are <br />reported. However, this entry needs to report existing storage capacity. It would be as-built less occupied <br />(accumulated) sediment storage. Please add existing storage capacities to the report. <br />Please call me if you have any questions. <br />Yours truly, <br />.>~ ~ ~~~ <br />Byro G.
